How should the production and management measures of asphalt mixing equipment be strengthened?
April 14, 2022
There is a close relationship between the scientific production and management of asphalt mixing equipment. Combined with relevant practical construction experience, there are the following suggestions:
1. Crew management
The crew is the main body of operating the asphalt mixing equipment. Only with excellent professional skills and the strengths of each crew member can the production and management level of the asphalt mixing equipment be improved. First of all, the crew members are required to hold a certificate, they are non-professional members, and they are not allowed to engage in professional work. For example, the weak current control system must be handled by operators with weak current knowledge and relevant work experience; The safety operation procedures shall not operate other types of work other than the work of the post; again, when working in one's own post, it is required to strictly abide by the labor discipline, and when necessary, it is necessary to make technical disclosures, otherwise it is impossible to leave the post.
2. Production organization management
Asphalt mixing equipment is a professional construction equipment, its safe operation is the focus of equipment production and management, and is also the basic premise to give full play to equipment efficiency. First of all, during the use of the equipment, the unit operators are required to undergo professional training on safe electricity use knowledge to ensure the safe operation of the equipment in terms of subjective behavior; secondly, the plant area of the asphalt mixing equipment needs to do a good job in protecting the corresponding safety facilities, such as Install lightning rods and equip with fire-fighting equipment, etc., and lay out eye-catching safety signs on the site; thirdly, the asphalt equipment itself should be equipped with safety protection measures, such as setting up equipment fire walls, etc., to ensure that the equipment is used in the best safe state.
4. Equipment maintenance management
(1) Effectively strengthen the optimization of personnel allocation
The maintenance of asphalt mixing equipment should run through the entire construction process to ensure that the equipment can be maintained before, during and after construction. Under normal circumstances, each asphalt mixing equipment needs at least 4 personnel for inspection and maintenance. One of them is responsible for cold material transportation and asphalt heating transmission, one is responsible for supplying fuel oil, conveying and processing mineral powder, and one is responsible for vibrating screen and trolley layer. A person operates the equipment. All personnel responsible for equipment inspection and maintenance need to be equipped with walkie-talkies to facilitate communication, and forklift operators also need to be equipped with walkie-talkies.
(2) Do a good job in all inspections
Before the official construction, it is necessary to check the air compressor and each cylinder, check whether the cylinder connecting bolts are stable, and also need to check the circuit. During the construction process, the inspectors should do their job well, report the problems in time, and carry out maintenance to eliminate the faults. After the construction is completed, the equipment should be maintained in time.
(3) Main points of maintenance work
The maintenance work mainly includes the following: filling the mixing shaft of the mixing tank with high temperature resistant lithium base grease; checking and strengthening the cylinder screw of the hot aggregate silo; timely removing the residual mixture inside the mixing cylinder and the trolley, etc. The first thing to do is to remove the residual mixture, which is mainly due to the difficulty in removing the viscous modified asphalt in the mixture after cooling. The mixing tank mainly relies on hot aggregate stirring to complete the cleaning, and the residual mixture inside the small town needs to be cleaned with the help of small electric picks and Luoyang shovels. Check the hydraulic oil in the cylinder filter cup every day, and replenish it in time if it is found to be insufficient. Fill the grease filling port every 20 days, and the gear oil of the reducer can be replaced once a year under normal circumstances.
5. Formulate equipment management system to improve equipment management level
The management of asphalt concrete equipment must be based on a strict system of use, maintenance and repair. The equipment management personnel shall formulate a management plan that conforms to the actual production in accordance with the requirements of the system. The equipment installation personnel, operators, management personnel and maintenance personnel shall strengthen the disclosure work, and arrange special personnel to conduct random inspections on the daily management work. At the same time, in the name of personnel management, establish reward and punishment measures for equipment management, and include the installation, maintenance, management, repair and use of equipment into the scope of rewards and punishments, so as to urge equipment managers to consciously improve their work responsibility and equipment management level, improve Equipment use efficiency and life, reduce equipment management costs.
Therefore, the application of asphalt mixing equipment requires maintaining the stability of equipment operation, and the failure of mixing equipment not only affects the efficiency of mixing equipment, but also may lead to the decline of asphalt mixing quality. Here, we improve the scientific level of the production and management of asphalt mixing equipment. On the one hand, the crew is required to hold a certificate, and when operating the equipment, it is necessary to strictly abide by the relevant safety operation procedures, so as to control the quality of the asphalt production process, and on the other hand The aspect is that during the use of the equipment, the unit operators are required to undergo professional training on safe electricity use knowledge, and do a good job in the protection of corresponding safety facilities, as well as carry out regular inspections, and timely repair and maintain the existing faults and hidden faults.
1. Crew management
The crew is the main body of operating the asphalt mixing equipment. Only with excellent professional skills and the strengths of each crew member can the production and management level of the asphalt mixing equipment be improved.

2. Production organization management
In the asphalt mixing process, it is required to control the quality of the asphalt production process. During the application of asphalt mixing equipment, the following technical details must be taken into account: First, according to the heating requirements of the asphalt, the temperature should be controlled within a suitable range, For example, the suitable temperature of ordinary asphalt is between 150 ℃ and 180 ℃, and then the heating time should be controlled according to the actual production situation. The operator needs to regularly check the fuel supply status and inspect the operation of the mixing equipment. If there is any abnormal problem with the equipment, report it to the captain in time; secondly, during the asphalt production period, the inspectors should check the operation of the equipment at any time, and it is strictly forbidden for non-equipment operators to operate the equipment. If it is found that the asphalt mixing equipment overflows due to improper asphalt mixing ratio Material problems should be dealt with in time, and there must be no mechanical disease operation; finally, after the production is completed, the operators should carefully clean the mixing equipment according to the specification requirements, and carry out lubrication and maintenance to ensure that the asphalt mixing equipment is in the best condition. Operating status.
Asphalt mixing equipment is a professional construction equipment, its safe operation is the focus of equipment production and management, and is also the basic premise to give full play to equipment efficiency.
