Description

Technical Field

[0001] The present invention relates to an integrated equipment for drilling, grouting, anchoring and net hanging in mines, belonging to the technical field of mine bolt support equipment. Background Technique

[0002] The support of mine roadways is mainly used to alleviate and reduce the movement of surrounding rocks, so that the roadway section will not be excessively reduced, and at the same time, to prevent the caving of the already scattered and damaged surrounding rocks.

[0003] Taking bolt support as an example, during the process of bolt support, it is necessary to first drill bolt holes, then hang the net, inject anchoring agents such as resin, and then knock in the bolts to fix the net; in the early stage of bolt support, YT28 pneumatic leg pneumatic rock drills were often used for manual drilling, and then manual net hanging, injection of anchoring agents, and installation of bolts; this kind of scheme has high working intensity, low operation efficiency, low support quality, and low safety factor. Therefore, in some subsequent mines, double-boom bolt drill jumbos are used instead. When the double-boom bolt drill jumbo works, one boom drills holes and the other boom installs bolts. Although it solves the initial technical problems such as low safety factor, because this scheme requires two sets of boom control systems, it has a large volume and complex operation. At the same time, the two booms are independent of each other, and it is difficult to align the holes during the process of installing bolts by the other boom after drilling is completed. That is, the initial technical problems such as high working intensity, low operation efficiency, and low support quality still exist, and manual net hanging and resin injection are still required, and the safety of personnel cannot be guaranteed during net hanging.

[0004] However, through research by the applicant, it is found that there are the following problems in the construction process of mine bolt drill jumbos:

[0005] At present, there are mainly three forms of mine bolt drill jumbos, all of which are improved by using the existing whole machine of mine tunneling drill jumbos:

[0006] 1. One of them is based on a single-boom mine hydraulic tunneling drill jumbo, and the operation of tunneling holes and bolt holes is realized by using a folding propulsion beam. This scheme can only realize the drilling operation, and the operations of net hanging, resin injection and bolt installation need to be assisted by personnel standing on the operation platform. During the operation of personnel, dangers such as cave-ins are likely to occur, and the installation speed is slow and the efficiency is low;

[0007] 2. One of them is based on a double-boom mine hydraulic tunneling drill jumbo, and one of the booms is modified into a bolt installation device. One boom is used to drill bolt holes and the other boom installs bolts. This scheme requires two sets of boom control systems, has a large volume and complex operation. At the same time, the two booms are independent of each other, and it is difficult to align the holes during the process of installing bolts by the other boom after drilling is completed; and this scheme can only realize the operations of drilling and bolt installation, and net hanging and resin injection still need to be manually operated. During the operation of personnel, dangers such as cave-ins are likely to occur, and it is impossible to form a full-process mechanized construction of bolt support to realize mechanized replacement of personnel;

[0008] 3. Based on a double - arm mine hydraulic tunneling jumbo, one of the arms is modified into an operation platform, and one drilling arm is used for drilling bolt holes. An auxiliary device for bolt installation is carried on the operation platform of the platform arm, which can assist manual mesh hanging and bolt installation. This solution can realize drilling, mesh hanging, and bolt installation operations. The mesh hanging and bolt installation operations require personnel to stand on the operation platform to assist. When personnel are hanging the mesh and installing bolts, dangers such as cave - ins are likely to occur, and the installation speed is slow, the efficiency is low, which is not conducive to replacing people with mechanization.
