Stoper

Abstract

The invention relates to a stopper which comprises a main machine and a two-stage air leg. The main machine consists of a machine head, a cylinder body and a handle body. The top end of an outer cylinder barrel of the two-stage air leg is hermetically connected with a lower port of the handle body through a fastening piece; a flow distribution hinged shaft is arranged on the wall of the handle body; and an operating arm consisting of an arm body, a hose and a control device is hinged on the flow distribution hinged shaft. The control device consists of a main machine operating valve and an air leg operating valve; control handles are respectively arranged on the main machine operating valve and the air leg operating valve; and the works of the main machine operating valve and the air leg operating valve can be controlled through rotating the control handle. After the operating arm is additionally increased in the invention, an operator can keep a certain distance with the stopper during the operation, so that the problems that rock magmas and falling-down rocks directly pound the operator, bits are blocked and the like are solved. The stopper has the advantages that the positioning and eye widening accuracy is good, and the main machine is not required to be dismounted during the replacement of gas-water needles and is a special device which not only can be used for vertical shaft and courtyard tunnelling and mining construction, but also can be used for roadway anchored bar support engineering construction.

Description

【Technical field】 [0001] The invention belongs to an upward rock drilling machine. 【Background technique】 [0002] In mine shaft and skyway excavation, mining and roadway bolting projects, it is necessary to drill a large number of rock holes with an upward direction and an angle of 60° to 90° with the horizontal line, especially the comprehensive promotion and application of roadway bolting technology. The demand for bolt holes on the roadway roof is increasing day by day. At present, the drilling equipment used for the above-mentioned operations is mainly divided into two categories: one is a pure rotary bolt drilling rig specially used for drilling bolt support holes in soft rock roadways, and the other is for drilling rock bolts in medium-hard rock roadways. Hole equipment, the former can basically meet the requirements of engineering technology, while the latter has many problems and needs to be continuously improved. [0003] The upward rock drill is a kind of drilli...

AI Technical Summary

Problems solved by technology

The machine has the following problems: 1. The air leg is a single-stage type, the telescopic stroke is small and the relative height is high, and it is difficult to adapt to drilling the bolt holes on the roof of the roadway in the roadway where the height and space are limited.

2. To replace the air and water needle device, it is necessary to disassemble the host, which is a heavy workload and inconvenient

3. The staff must stand directly under the machine, and the magma and possible falling rocks will be poured directly on the operator, causing many safety hazards and harsh working environment

However, this machine has the following deficiencies: 1. Like the upward rock drill, the operator must stand directly below the machine, and the magma and possible falling rocks will directly pour on the operator, resulting in many potential safety hazards and harsh working conditions

2. The telescopic stroke of the two-stage air leg is large. After the air leg is fully extended, the operator cannot control the main machine and the air leg because the hand cannot touch the control handle of the main machine, and it is easy to lose control and there is a major safety hazard.

3. The air leg and the main engine are connected by a hinged shaft, and the two are not on the same axis. Therefore, it is easy to cause problems such as inaccurate opening positions and straightness of the bolt hole that cannot meet the technical requirements of bolt support.

The machine adds an air leg control arm on the hinge shaft, through the control mechanism on the air leg control arm, the extension and retraction control of the two-stage air leg is realized, thus solving the problem that the operator must stand directly under the machine , the magma and possible falling rocks will be poured directly on the operator, but there are still problems that the main engine cannot be controlled when the air leg is fully extended and the drill is stuck, and the opening position is not accurate, and the straightness of the anchor hole cannot meet the requirements of the anchor. Technical requirements for rod support

[0006] To sum up, there is no ideal equipment specially designed for drilling bolt holes in roadways above medium-hard rocks.
