Exchangeable crawler wheel of loading machine

Abstract

The invention discloses an exchangeable crawler wheel of a loading machine, which adopts a middle support base frame, wherein the base frame is formed by welding left and right web plates, a lateral connection plate, a lower connection plate and an outer shaft sleeve of a drive wheel. An inner shaft sleeve of the drive wheel is connected with the outer shaft sleeve of the drive wheel through a pair of conical roller bearings, and a shifting plate is connected to the two ends of the inner shaft sleeve of the drive shaft through bolts; the lower end of the base frame is connected with a support wheel set, a guide wheel set and a tension wheel set, wherein the support wheel set has a three-axis swing structure, so the impact load of the crawler wheel on the pavement is reduced; the guide wheel set and the tension wheel set are connected with the base fame through a clamping type structure; and the support wheel, the guide wheel and the tension wheel adopt a glue coating structure. A crawler belt adopts a gear wheel structure, and aramid fiber cord threads are used in the crawler in place of interior steel wires, so the weight of the crawler belt is effectively reduced, and a heavy crawler wheel product capable of being exchanged with the current tyre is obtained.

Description

technical field [0001] The invention relates to a replaceable track wheel, which is an all-terrain triangular track wheel unit capable of replacing tires of a four-wheel drive loader (type 50 loader). Background technique [0002] Track wheel is a tire structure product with both tire and track functions. It is mainly used to solve the problem of insufficient traffic capacity of vehicles in deserts, swamps, ice and snow, and soft ground. Compared with ordinary tires, track wheels have a larger contact area. , Reduce the grounding specific pressure of the equipment, good adhesion performance, large traction force, good stability, etc., and can be used in non-road conditions such as deserts, swamps, and fields. [0003] During the fight against ice and snow disasters in southern my country in 2008 and the emergency rescue process of snow disasters in Xinjiang in 2009, when the loader was walking and operating on ice and snow, muddy, sandy and other soft ground, the tires were ...

Problems solved by technology

[0003] During the fight against ice and snow disasters in southern my country in 2008 and the emergency rescue process of snow disasters in Xinjiang in 2009, when the loader was walking and operating on ice and snow, muddy, sandy and other soft ground, the tires were prone to slipping, sinking, and unstable center of gravity. , resulting in a great reduction in its passability and operating capacity, which affects the efficiency and progress of emergency rescue work; and the existing track wheel products mainly have the following two problems: one is that the carrying capacity is small, and it cannot be applied to a loader of more than 20 tons; The second is that the carrying capacity meets the requirements of use without interchangeability, and the interchangeability with the tires on the loader cannot be realized, which is very inconvenient to use
