Belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient programmed control and automatic operation. The self feeding cement mixer truck cannot lack belt conveyor and use belt conveyor to transport materials. Therefore, it also needs to pay attention to maintenance when in use.
Maintenance of transmission device. Add lubricating oil before use. The brand of lubricating oil is lkc100150# medium load extreme pressure industrial gear oil. Lubrication of roller bearings. The plain roller bearing is UCP series (commonly used ucp214), which is lubricated with grease and filled once a day.
Cleaning of roller and idler. Since the cement mixer truck is loaded, the accumulated materials on the roller and idler are often cleaned. Too much accumulated materials will affect the operation of the belt and lead to deviation. Regularly check the wear degree of the sand scraping device, and replace the sand scraping device in time after it is worn to a certain extent. The rubber retaining edge is seriously worn and should be replaced in time when materials are scattered.
Prevention and treatment of interface fracture and transverse tear. The joint vulcanization treatment is unqualified; The impact load is too large, and the weak part breaks under the influence of alternating stress; The interface direction is not suitable for the belt movement direction; If it is used for a long time, the belt will be seriously damaged.
When using the self loading cement mixer truck, the load shall be reduced as much as possible, especially the belt with counterweight tensioning device. The counterweight shall be controlled within 200kg ~ 300kg, and it is better not to slip in rainy season. Patrol inspection shall be strengthened to prevent foreign matters from blocking the belt and scratching the belt; Strengthen the training of belt assembly personnel to prevent reverse installation of belt interface.
When the mixer truck is parked in the open field, the mixing drum shall be reversed before loading, and the ponding (or rainwater) and sundries in the drum shall be unloaded to ensure the quality of concrete transportation. During the no-load operation and concrete transportation of the mixer truck, the mixing drum shall not stop rotating, so as to avoid local collision damage of the raceway and roller or segregation of the concrete.
In addition, when driving on the road, the extended chute must be turned over and placed on the discharge chute, hung firmly with a hook, and then turned to the position perpendicular to the vehicle body. The discharge chute and the extended chute are locked on the frame with a locking device to prevent shaking due to instability, resulting in personal injury accidents and affecting the operation of other vehicles.
This is the relevant content of precautions for belt conveying of self feeding cement mixer truck. Of course, regular inspection and maintenance are essential. I hope it will be helpful to you. For more information, please visit www.sdzkjf.com Cn for consultation.
