Single-chain driven rear caterpillar track assembly

Abstract

The invention discloses a single-chain driven rear caterpillar track assembly. Free wheel axles are transversely arranged at the front end and the rear end of a longitudinal beam in a penetrating mode, a bearing chamber is arranged above the middle of the longitudinal beam, a front inclined supporting beam and a rear inclined supporting beam are symmetrically arranged between the bearing chamber and the longitudinal beam, and a front free wheel and a rear free wheel are mounted at the two end of each free wheel axle. A driving wheel is arranged on the rear side of a driving wheel support upper cross beam and is connected with the free wheels, tensioning wheels and supporting wheels through a rubber caterpillar band, a driven chain wheel is arranged on one side of the driving wheel, a driving wheel axle is sleeved with the driven chain wheel, and the driven chain wheel is connected with the driving chain wheel through a chain. The framework of the single-chain driven rear caterpillar track assembly can ensure position and size accuracy through mutually matched positioning structures among the parts, the structural strength and stability of the whole framework can be good, the welding precision is guaranteed, the reliability is good, the manufacturability of assembly manufacture is good, and the single-chain driven rear caterpillar track assembly has low-speed, heavy-load and smooth and steady characteristics and terrain adaptability.

Description

technical field [0001] The invention relates to a photovoltaic cleaning system, in particular to a single chain drive rear crawler assembly of a cleaning system of a large-scale ground photovoltaic power station. Background technique [0002] Photovoltaic module automatic cleaning equipment is a device that takes the cleaning of photovoltaic modules of large-scale ground photovoltaic power stations as its work task. It runs at a low speed higher than 1.5km / h, and the equipment is mainly operated in the wild in the northwest Gobi desert area. [0003] Chinese patent ZL201520324286.9 on October 7, 2015 discloses a large-scale ground photovoltaic power station cleaning system chain drive rear crawler assembly, which consists of rubber crawler, driving wheel, load-bearing wheel, tension wheel, load-bearing bracket, supporting wheel, chain wheel etc. The above-mentioned chain drive rear crawler assembly is replaced with the rear wheel of a light truck. Although it has the chara...

AI Technical Summary

Problems solved by technology

[0004] 1. The main shaft bearing chamber adopts the method of double round nuts tightened together + stop washers for round nuts, which is difficult to assemble and debug, and is limited by the material and machining accuracy of round nuts and stop washers. In actual use, there are the following Problems: 1) The dimensional accuracy of the round nut is poor, the gap between the thread teeth is too large, and the verticality between the nut thread and the end face of the nut is poor, resulting in uneven locking force, uneven force on the bearing, poor locking effect, and easy loosening of the spindle; 2 ) The thickness of the round nut is not enough, the chamfer of the thread teeth is not standard, the number of teeth is too small, and the locking force is not enough; 3) The thickness of the stop washer is not enough, the stop effect is not good, and it is easy to break

The above problems lead to loose faults when the spindle is subjected to repeated axial impact forces during use

[0005] 2. The structure of the load-bearing bracket is relatively complicated, and the manufacturing accuracy is poor. It is difficult to guarantee the position and dimensional accuracy of each component, and it does not meet the requirements of consistent production.

[0006] 3. Double chain transmission is adopted, and the precision requirements of the synchronous transmission of the two chains are high, making it difficult to manufacture and assemble
