Description

Technical Field

[0001] The present application relates to the technical field of anchor bolt installation, and in particular to an anchor bolt installation device for mining. Background Art

[0002] Mining anchors, also known as anchor rods, are the most basic component of contemporary coal mine tunnel support. The anchor rods penetrate deep into the stratum, one end is connected to the engineering structure, and the other end is deep into the stratum, playing a role of fixing and supporting. During the advancement of the coal tunnel, the coal mining face continues to advance forward, which will cause the pressure on the shaft wall to increase, easily causing the shaft wall to crack and collapse. The anchor rods can support the top and side of the coal tunnel to prevent it from collapsing and ensure the safety of the miners.

[0003] Application No. 202022778389.6 discloses an anchor bolt installation device for mining, including a box body, an inlet pipe, an outlet pipe, a servo motor and an anchor bolt socket, etc. By starting the servo motor, the output end of the servo motor rotates, the output end of the servo motor rotates, the first concave rotating wheel rotates, the first concave rotating wheel rotates, the first connecting column rotates, the first connecting column rotates, the first gear rotates, the second gear rotates, the second connecting column rotates, and the second concave rotating wheel rotates. By inserting the anchor bolt into the anchor bolt socket and the inlet pipe, when the anchor bolt is inserted to When it reaches between the first concave rotating wheel and the second concave rotating wheel, the first concave rotating wheel and the second concave rotating wheel are rotated to move the anchor rod into the outlet pipe, thereby realizing the installation of the anchor rod, and the expansion and contraction of the telescopic rod allows the box to rotate through the two first rotating shafts, and the angle of the outlet pipe can be changed by rotating the box, so that the anchor rod can be installed at different angles. Four internal threaded holes are drilled through the lower end of the base, and the four internal threaded holes are all threadedly connected with internal threaded holes, so that when the ground is uneven, the distance between the supporting foot and the base can be achieved by rotating the screw rod, so that the box can be placed flat on an uneven ground.

[0004] However, in use, there are the following defects:

[0005] Although two concave rotating wheels are used to move the anchor rods in the inlet pipe and the outlet pipe to complete the installation, during the support process, different surrounding rock reinforcements require the use of anchor rods of different sizes and lengths, resulting in the anchor rod sockets being stuck when inserting larger anchor rods, while smaller anchor rods cannot move forward under the drive of the concave rotating wheels, thus affecting the installation effect. Utility Model Content

[0006] The purpose of the present application is to provide an anchor installation device for mining, which solves the problem proposed in the background technology that although two concave rotating wheels are used to move the anchor in the inlet pipe and the outlet pipe to complete the installation, during the support process, different surrounding rock reinforcements require the use of anchors of different sizes and lengths, resulting in the anchor socket being stuck when a larger anchor is inserted, and the smaller anchor cannot move forward under the drive of the concave rotating wheel, thus affecting the installation effect.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: an anchor bolt installation device for mining, comprising a base, a No. 1 telescopic rod, a top box, a transmission rod, a fixing bolt and a limiting arc plate, wherein positive slide grooves are provided on both sides of the top of the base, and side slide grooves are provided on the left and right side walls of the base, the positive slide grooves are connected to the side slide grooves, the bottom of the No. 1 telescopic rod is laterally slidably connected on the inner side of the positive slide groove, the top end of the side wall of the No. 1 telescopic rod is fixedly connected with a support shaft, the other side of the support shaft is movably connected to the center of the side wall of the top box, a cross bar is fixedly welded on the top of the top box, a No. 2 telescopic rod is fixedly installed below the cross bar, a driving motor is fixedly installed on the bottom of the side wall of the No. 2 telescopic rod, and the side wall of the No. 2 telescopic rod on the opposite side of the driving motor is fixedly connected to one end of the transmission rod, and the other end of the transmission rod is fixedly connected to the upper concave rotating wheel.

At the same time, the angle and position can be freely adjusted to adapt to different installation environments through the support shaft, torsion switch and positive slide groove. According to the inclination degree and installation position of different surrounding rocks in the mine tunnel, the support shaft is rotated to adjust the angle of the top box and fix it with the torsion switch. If it is inconvenient to approach the base, the No. 1 telescopic rod can be directly slid on the surface of the positive slide groove, so that the top box follows the lateral movement, so that the opening can be aligned with the holes opened at different positions on the surrounding rock, which improves the installation efficiency and practicability of the device.
