Description

A kind of high driving bulldozer final drive component balance sling

Technical field

This utility model is related to a kind of device for lifting high driving bulldozer final drive component, belongs to workshop tools skill Art field.

Background technology

Height drives its end that is mainly characterized by of bull-dozer to be driven（Also it is drive sprocket）Departing from walker, with braking in a turn Clutch and central transmission arrange that on the same axis as viewed from bull-dozer side, crawler belt is shaped as triangle, this structure Drive sprocket can be prevented effectively from and directly bear temporary impact load from ground, the life-span that can make whole drive system improves about 30%.It is typically all first then again will to constitute the two together with eventually transmission is attached together with braking in a turn clutch during practical set Whole transmission component integral hoisting enter whole machine, because whole transmission component installation site is high, weight is big（About 800kg）, in geometry The heart and deviation of gravity center are more and without suspension centre, in addition many workpieces and hydraulic packing of the transmission with braking in a turn clutch eventually Part is all afraid of to collide with, and to the lifting of component very big difficulty is caused, and greatly reduces the efficiency of assembling of product, increased the work of workman Intensity.Therefore how while product safety is ensured, the efficient lifting of whole transmission component is realized, always perplexs relevant technology The difficult problem of personnel.

Utility model content

The purpose of this utility model is the drawback for prior art, there is provided a kind of high driving bulldozer final drive component Balance sling, to improve the efficiency of assembling and assembling quality of bull-dozer, mitigates the labor intensity of workman.

Problem described in the utility model is with following technical proposals realization：

A kind of high driving bulldozer final drive component balance sling, composition includes that main suspension hook, auxiliary suspension hook and center of gravity are inclined From segmental support, the bill of the main suspension hook and auxiliary suspension hook is hooked in respectively on the eventually boss of the sprocket both sides of transmission, main suspension hook and The neck of hook of auxiliary suspension hook by two spacing bearing pin connections, insert on the neck of hook of main suspension hook by one end of the deviation of gravity center segmental support Suspension ring in, the other end is connected with the suspension hook of crane.

Above-mentioned high driving bulldozer final drive component balance sling, the neck of hook of the auxiliary suspension hook arranges two, their phases Neck of hook both sides that are mutually parallel and being located at main suspension hook respectively.

Above-mentioned high driving bulldozer final drive component balance sling, the spacing pin shaft hole on the neck of hook of the auxiliary suspension hook is equal For circular hole, a spacing pin shaft hole on the neck of hook of the main suspension hook is circular hole, and another spacing pin shaft hole is slotted hole.

Sprocket as suspension centre, by the cooperation of two suspension hooks the quick, reliable of whole transmission component is realized by this utility model Hook, and make component keep balance by deviation of gravity center segmental support, it is with low cost with simple structure, it is easy to operate, safe etc. Feature, not only increases the efficiency of assembling and assembling quality of bull-dozer, and can mitigate the labor intensity of workman.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described in further detail.

Referring to Fig. 1～Fig. 6, this utility model includes main suspension hook 4, auxiliary suspension hook 5, spacing bearing pin 6 and deviation of gravity center arch Frame 7.

First 3 being driven during practical set by braking in a turn clutch 2 and eventually, whole transmission component is connected into by alignment pin, Whole transmission component is steadily positioned in Special station tool to carry out spacing, and prevents whole transmission component from being collided with or having different Thing is fallen in whole transmission component.

The whole transmission component balance sling of assembling, is first placed on the neck of hook of main suspension hook 4 between two necks of hook of auxiliary suspension hook 5, The bill of two suspension hooks is relative, and with a spacing bearing pin 6 through the slotted hole on the neck of hook of main suspension hook 4（Spacing pin shaft hole）With it is auxiliary The circular hole helped on the neck of hook of suspension hook 5（Spacing pin shaft hole）So that can rotate against between main suspension hook 4 and 25, so Hook the boss of the sprocket both sides of whole transmission component respectively with the bill of main suspension hook 4 and auxiliary suspension hook 5 afterwards, then it is spacing with another It is spacing that bearing pin 6 passes through another spacing pin shaft hole of main suspension hook 4 and auxiliary suspension hook 5 to carry out, and an elliptical closed suspension ring 10 are mounted in The upper end of main suspension hook 4, through oval suspension ring 10, the other end hangs on crane hook the one end of deviation of gravity center segmental support 7.Start After crane, by the effect of deviation of gravity center segmental support, whole transmission component can be made generally in horizontality, deviation of gravity center arch The size of frame is drawn by calculating according to the barycentre offset of whole transmission component.This structure can be prevented effectively from whole transmission Component collides with assembling process with frame rear axle box welding body 1, makes the connection of whole transmission component and rear axle box welding body It is safe and reliable, convenient, fast.
