As an important part of the tensioning device, the trolley mainly provides the necessary belt tensioning capacity for the belt conveyor to ensure the stability of the belt conveyor during starting, running and braking. The chain conveyor is a transmission device that uses standard chain plates as the bearing surface and is driven by a motor reducer. The chain conveyor is composed of power unit, drive shaft, roller, tensioning device, sprocket, chain, bearing, lubricant, chain plate, etc. Chain conveyor is one of the mechanized storage and transportation systems of lime production enterprises Auxiliary equipment, its main function is to feed processed or unprocessed materials from a certain equipment (hoppers, storage bins, etc.) to the receiving equipment or transportation machinery continuously and evenly. The mesh belt is a kind of The static friction method is used to drive a machine that transports materials in a continuous manner by friction. Because the platform of this machine needs to be used repeatedly, it is rarely used alone. Instead, it forms a horizontal or vertical circulation system with various special machines such as jacking translator and jacking indexer. Logistics conveyor belt belt with traction parts The conveyor belt generally includes: traction parts, load-bearing members, driving devices, tensioning devices, redirecting devices and supports. The traction parts are used to transmit traction, which can be conveyor belts, traction chains or steel wire ropes; the load-bearing components are used to carry materials, including hoppers, brackets or spreaders, etc.; the driving device powers the conveyor, usually by electric motors, reducers and Brake and other components; the tensioning device generally has two types of screw type and heavy hammer type, which can maintain a certain tension and sag of the traction member to ensure the normal operation of the conveyor belt; the support member is used to support the traction member or load-bearing member, which can be Rollers, rollers, etc. The temperature of the delivered material is less than 60°C. The captain and assembly form can be determined according to user requirements, and the drive can be an electric drum or a drive device with a drive frame. The quality of the tensioning car directly affects the stability of the tensioning device, and then affects the overall performance of the belt conveyor, which is related to the safe operation and service cycle of the belt conveyor. With the continuous expansion of belt conveyor applications, it is particularly important to design the tension car reasonably. There are two belt conveyor tensioning devices with a tension trolley structure: one is a heavy-duty vehicle tensioning device, and the other is a hydraulic vehicle tensioning device. The improvement plan of the tension trolley introduced in this article is to add a set of locking structure between the tension trolley and the track at the four-roller installation position of the original belt conveyor tension trolley. The locking structure is composed of a support plate and a locking bolt (composition: head and screw). Schematic diagram of the improvement plan of the belt conveyor tensioning trolley. Schematic diagram of belt conveyor tension car improvement scheme In this scheme, the support plate mainly plays a role of support and protection, and the locking bolt can adjust and control the gap between the tension car and the track. In the normal use of the belt conveyor, the gap between the tensioning car and the crawler is controlled by adjusting the locking bolt. Due to the long-term use of the belt conveyor in the production process, it will lengthen the conveyor belt and cause some equipment failures. Therefore, it must be checked and adjusted before use to ensure the safe operation of the conveyor equipment. The tension force of the belt conveyor belt is generated by tightening the belt. When tilting upward, the gravity of the belt's own weight will also generate initial tension. For reliable operation, the equipment needs to be checked before operation and ensure that the tension of the conveyor belt is within a certain range. Please pay attention to the following points when adjusting: The main results are as follows: (1) Generally, the loading conveyor belt will be adjusted to the proper strength for the first time, and the conveyor belt between two adjacent rollers should not sag too much, causing materials to fall into After the belt is conveyed, it will not roll off after being supported by the idler rollers. (2) When adjusting the conveyor belt, the operation of the equipment after stretching must be considered. Avoid the occurrence of belt deviation. A deviation detection device can be considered, and when a deviation occurs, it will immediately warn the situation. (3) When the belt (Belt) conveyor is running, consider the pulling force it bears when conveying the material, and choose a suitable belt. (4) Adjust the position of the conveyor belt rollers.
