Triangular rear crawler belt assembly

Abstract

The invention discloses a triangular rear crawler belt assembly. Tensioning wheels are connected with a driving wheel and dissociation wheels through a rubber crawler belt, outer teeth on the circumferential face of the driving wheel are meshed with inner teeth of the inner surface of the rubber crawler belt, steel baffles are installed on the two end faces of the driving wheel in an attached mode, and long bolts penetrate through assembling holes in the two steel baffles and via holes in the outer teeth, so that the two steel baffles and the driving wheel are fixedly connected together; an inner end of a driving main shaft is arranged in the driving wheel in a penetrating mode, a flange plate is welded to the end of the inner end of the driving main shaft, and a clamping plate is installed on the driving main shaft in a sleeving mode and fixedly connected with the driving wheel and the flange plate through bolts which are distributed circumferentially in an even mode. By means of the triangular rear crawler belt assembly, rigidity and bearing capacity of the high molecular material driving wheel are effectively improved, and stability of internal materials of the high molecular material driving wheel is guaranteed; by means of a driving main shaft assembly which is of a steel integrally-welded structure, high-rigidity and high bearing capacity requirements of a low speed and heavy duty triangular crawler belt can be satisfied sufficiently, materials are saved, and production cost is lowered.

Description

technical field [0001] The invention relates to a photovoltaic cleaning system, in particular to a triangular rear track assembly of a large-scale ground photovoltaic power station cleaning system. Background technique [0002] Photovoltaic module automatic cleaning equipment is a kind of equipment that takes the cleaning of photovoltaic modules of large-scale ground photovoltaic power plants as its task. The speed is higher than 1.5km / h, and the equipment is mainly operated in the wild in the Northwest Gobi Desert. [0003] Chinese patent ZL201520323614.3 disclosed on October 7, 2015 a triangular rear track assembly of a large-scale ground photovoltaic power station cleaning system, which consists of a rubber track, a driving wheel, a free wheel, a tensioning wheel, a load-bearing bracket, an adapter plate, a pendulum It is composed of arm, limit stopper, stainless steel protective plate and tension frame. The above-mentioned triangular rear track assembly is replaced wit...

Problems solved by technology

However, in actual use, due to the harsh operating environment, the swing drive spindle of the free wheel assembly may be locked, resulting in the loss of the free function of the free wheel assembly

[0006] 3. 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.
