Supporting walking system for heavy transportation machinery

Abstract

The invention discloses a supporting walking system for heavy transportation machinery, belonging to the field of heavy transportation equipment. The supporting walking system comprises a hydraulic control system and supporting walking trolleys; wherein the supporting walking trolley consists of an idler wheel car, an oil cylinder, a top supporting seat and a supporting seat; a sleeve at the upper part of the top supporting seat is sleeved in the inner cavity of the supporting seat and matched with the inner cavity in a sliding way; the oil cylinder is arranged in the sleeve at the upper part of the top supporting seat; the free end of the oil cylinder stretches and props at the bottom of the top supporting seat; the fixed end of the oil cylinder is connected with the top of the supporting seat; a ball head at the lower end of the top supporting seat is hinged with a ball hinged seat at the top of the idle wheel car; and the walking supporting trolleys are orderly arranged and connected with the bottom of a lower transverse beam of the heavy transportation machinery by the supporting seat for supporting the walking of the heavy transportation machinery. According to the supporting walking system for heavy transportation machinery, the advantage of large loading capacity of the idle wheel car is fully used to totally avoid the rail gnawing phenomenon; the influence of unbalance loading on the walking wheel is greatly reduced by releasing degree of freedom due to the ball hinged structure arranged between the idle wheel car and the oil cylinder; and the supporting walking system can meet the requirements of different wheel pressure conditions by installing the walking supporting trolleys with different quantities.

Description

Technical field: [0001] The invention relates to a support running system for heavy transport machinery, which belongs to the field of heavy transport equipment. Background technique: [0002] There are usually two types of supporting running systems for existing transport machinery: [0003] 1) It is composed of rim-type traveling wheels, balancing devices and tracks. [0004] 2) Composed of tire-type traveling wheels and balancing devices [0005] During the operation of transport machinery, there are strict requirements on wheel pressure. If the load of the transport machinery is too large, in order to ensure that the wheel pressure is within the allowable range, the existing technology usually adopts the method of increasing the number of running wheels to reduce the wheel pressure. In order to make the wheel pressure of each wheel uniform, a balanced trolley type is used support device. There are some limitations in the design of this balanced trolley-type support d...

AI Technical Summary

Problems solved by technology

There are some limitations in the design of this balanced trolley-type support device: if the load capacity of the transport machinery and its own weight are very large, a large number of running wheels must be used, and the strength of the running wheels is very high. Once there are too many running wheels , in order to ensure that the force on each wheel is the same in theory, it is necessary to set up a multi-level equalization device, so that the lower beam of the transport machinery must have enough space to install the equalizer and the running wheels. influential

If the height of the lower beam is too high, it is easy to produce unbalanced load and rail gnawing

What's more, the support point is too high, which leads to the instability of the transport machinery in the main plane
