Anchor drilling machine independent rack for machine

Abstract

The independent frame of the mechanical rock bolter overcomes the problem that the existing drilling rig frame has a complex structure and a large volume, and is limited by the width of the roadway and the height of the roof of the roadway, and it is difficult to arrange multiple frames. The sliding guide rail, the first guide post oil cylinder and the second guide post oil cylinder form a two-stage sliding guide rail. The drilling rig sliding bracket, the drilling rig oil cylinder, the top plate and the bottom plate support oil cylinder, and the swing side swing oil cylinder and bracket are also installed on the drilling rig frame, which is beneficial The effect is that the sliding guide column cylinder and its piston rod play multiple roles of cylinder, guide rail and mutual support. The structure is compact and ensures the strength and rigidity of the entire frame. The drilling rig sliding bracket is located at the bottom of the drilling rig bracket. The secondary sliding makes The shorter drilling rig has a large stroke and also has the function of temporary support, which enhances the safety and stability of the anchor protection work. The compact structure design enables multi-frame installation when realizing the integration of digging and anchoring On fully mechanized excavator or continuous miner.

Description

technical field [0001] The invention belongs to the technical field of tunneling and supporting in coal mine roadways, and in particular relates to an independent machine frame of a bolter drilling machine used for an integrated mechanized excavation machine and a continuous mining machine. Background technique [0002] In the prior art, the support work of the roadheader after the roadway is excavated is a difficult, complicated and extremely inefficient work. The main reason is that the split work of the roadheader and the bolter causes a lot of waste of time, and the effective working time The ratio is very small; manual bolting is not only labor-intensive, but also requires a large number of personnel, so the efficiency is very low. Therefore, there is a great need for an airborne bolter that can be quickly carried out during or immediately after the excavation of the roadheader. The bolt support work can improve the working efficiency of the roadheader, reduce the labor...

Problems solved by technology

But because this utility model installs the bolter on the side of the cutting part of the roadheader to realize the integrated structure of the bolter and the cutting part of the roadheader, this structure has brought the following problems: one is to install the anchor The installation of the rod machine on the side of the cutting part of the roadheader affects the working range of the cutting part of the roadheader, and also affects the operator's line of sight when cutting; Strong, it will seriously affect the safe service life of the bolter; the third is that when the cutting part is cutting, there will be a large amount of mineral fragments and dust or piles on the cutting part when the roof falls, which will cause the bolter The fourth is that when the utility model needs the work of the bolter, the bolter needs to rely on the lifting and swinging of the cutting part and the function of the bolter itself to complete the anchoring work of the roadway bolt. Safety production has formulated a series of standardized operating standards. When carrying out anchor protection work, it is required to stop all roadheaders. This does not allow the use of lifting or rotation of the cutting part of the roadheader to cooperate with anchor protection work during anchor protection work. Like this, the structure of this utility model just can't work

However, all telescopic parts in this invention need to be provided with corresponding guide parts, and the oil cylinder only plays a role in power. The fixing or working angle adjustment structure of the drilling rig in this invention is more complicated, and the fixing is achieved by tightening or loosening the compression handle. The purpose of the drilling rig or the working angle of the drilling rig is that the work efficiency is very low. In general, the structure of the invention is complicated, resulting in a relatively bloated and bulky structure, which is not conducive to the arrangement and use of the coal mining machinery and the narrow space in the roadway
