Adjustable limiting device applied to underground scooptram

Abstract

The invention particularly relates to an adjustable limiting device applied to an underground scooptram, which comprises a first fixed block and / or a second fixed block, wherein the first fixed block is in fixed connection fit with a boom or rocker, and the second fixed block is in fixed connection fit with a bucket. The adjustable limiting device further comprises adjusting pads which are in detachable fit with the first fixed block and / or the second fixed block, and the adjusting pads are in contact fit with each other, or the adjusting pads are in contact fit with the corresponding second fixed block and / or first fixed block. The whole adjustable limiting device is more flexible in mounting. The fixed blocks serves as bases for fastening the adjusting pads, both the thickness and the size of each adjusting pad can be standard, and in practice, the adjustable limiting device can be reused only by reasonably inserting and fixedly connecting a certain amount of adjusting pads of certain thickness according to a gap between actual fitting faces of the boom or rocker and the bucket, and the whole adjustable limiting device is convenient in mounting and high in efficiency.

Description

technical field [0001] The invention specifically relates to an adjustable limiting device applied to an underground scraper. Background technique [0002] Underground LHDs are mainly used in underground mines to shovel and transport loose materials after blasting. They can also be used in tunnel projects such as railways, highways, and hydropower. They are suitable for harsh working conditions, narrow, low, and muddy job sites. work surface. Between the bucket and the boom or between the bucket and the rocker, the scraper must be supported by a limit block, so that it can be in two positions: the retracted bucket position after shoveling and the dumping position where the boom is lifted to the highest point In the state, it can always ensure the stability of the working mechanism, protect the oil cylinder, and at the same time play the role of shaking off the mineral material. The existing limit blocks often have the following defects: First, due to the influence of compr...

AI Technical Summary

Problems solved by technology

The existing limit blocks often have the following defects: First, due to the influence of comprehensive factors such as welding errors and processing errors, the production of limit blocks in the past is based on on-site measurement, drawing, processing and welding, which is highly specific and complicated. , many people are involved, and the efficiency is low; secondly, the limit blocks are designed in one piece, which is heavy and difficult to operate, and the operation space is limited during welding, and the appearance is difficult to guarantee; When the block is used, it needs to be welded at the tipping position where the arm of the scraper is lifted to the highest point, and there is also a big safety hazard
