Description

Technical Field

[0001] The utility model relates to a vehicle-mounted drilling and anchor removal machine, belonging to the technical field of coal mine excavation tunnels. Background Art

[0002] There are huge safety hazards and high labor costs in the work of withdrawing anchors and removing tops in fully mechanized mining faces in underground coal mines. At present, almost all coal mines use the most primitive manual anchor remover to carry out the anchor removal and top removal operations. In this way, only the anchor and anchor bolt nut can be removed, and the anchor cable and anchor bolt cannot be taken out at all. When using the anchor remover to remove the top, 2-3 workers are required to hold the anchor jack or nut remover by hand, stand on the temporary construction scaffolding, and several people hold the anchor jack or nut remover to withdraw the anchor together, and at the same time direct the ground staff to manually pressurize the power pump, and then use the anchor jack after the anchor or nut is loosened. After removing the anchor jack or nut remover and returning the anchor jack or nut remover to the surface, workers return to the surface to dismantle and transfer the scaffolding. This complete process takes at least 2-3 hours to remove one or two anchors, costing the mine significant labor costs over the years. Furthermore, after the anchors are removed, the rock and coal blocks at the tunnel roof are at risk of collapse, making personnel safety impossible to guarantee. Furthermore, most anchors cannot be effectively and completely removed. Once the anchors are mixed with the coal and enter the belt, they can easily tear the belt, causing major production accidents and significant economic losses to the coal mine. If the anchors or nuts are not removed, the fully-mechanized mining roadway will fall into disrepair over time, and most of the anchors will rust and fall off, causing the entire roadway to collapse. Hazardous gases in the collapsed roadway will flood into the production working face, causing workers to inhale the harmful gases and suffer from poisoning and suffocation, which will harm their health. Therefore, any safety accident can have catastrophic consequences for coal mine safety. Summary of the Invention

DETAILED DESCRIPTION

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1As shown, in this embodiment, a vehicle-mounted drilling anchor winch is powered by a hybrid power source (emulsion and electric motor are switchable). The anchor winch includes a frame 1 with crawler tracks 2 provided on the left and right sides of the bottom of the frame 1. The crawler tracks 2 drive the frame 1 to move. A first rotary worktable 3 is provided on the frame 1, and a boom connection base 17 is provided on the first rotary worktable 3. The boom connection base 17 is hinged to one end of the tilted boom 6. The boom connection base 17 is connected to the bottom of the boom 6 via a boom hydraulic cylinder 7. The first rotary worktable 3 drives the boom connection base 17 to rotate 360 degrees about the Y axis, driving the boom 6 to rotate synchronously. The boom hydraulic cylinder 7 drives the boom 6 to rotate and swing up and down about the hinge point. The other end of the lifting boom 6 is hinged to the lifting arm 10. A lifting arm hydraulic cylinder 18 is provided on the top of the lifting boom 6. The cylinder body of the lifting arm hydraulic cylinder 18 is hinged to the lifting boom 6. The extension rod of the lifting arm hydraulic cylinder 18 is connected to the lifting arm 10. The lifting arm hydraulic cylinder 18 drives the lifting arm 10 to swing up and down around the hinge point. A second rotary table 11 is provided on the outer side of the lifting arm 10. A slide seat 8 is provided on the second rotary table 11. The slide seat 8 is perpendicular to the center line of the second rotary table 11. A slide 12 is fixed in the slide seat 8. A transverse cylinder 15 is provided on the top of the slide seat 8. The cylinder body of the transverse cylinder 15 is fixed to the slide seat 8. The extension rod of the transverse cylinder 15 is fixedly connected to the slide 12. The transverse cylinder 15 drives the slide 12 to extend from the slide seat or retract into the slide seat, thereby expanding the travel of the slide. The second rotary table 11 drives the carriage seat 8 to rotate 360° around the X-axis, thereby driving the carriage to move synchronously. A slide 16 is mounted on the carriage, which has two sliders. One slider is equipped with a working head, which is bolted to one slider. Tightening or loosening the bolts facilitates head replacement. A support seat 13 is mounted on the other slider. During drilling, the working head is a drilling head 14, with a drill rod inserted through the drilling head and one end of the drill rod positioned within the support seat. The carriage and drilling head are then controlled to approach the tunnel roof, where they rotate the drill rod, which then drills a hole in the tunnel roof around the anchor rod, loosening the tunnel roof around the anchor rod. After drilling, the carriage and drilling head are controlled to move away from the tunnel roof and withdraw to a safe position. The drilling head is removed, and a chuck is installed. The chuck is then controlled to approach the anchor rod, clamping it. The carriage and chuck are then controlled to move along the carriage seat, driving the anchor rod to move synchronously, thereby achieving anchor withdrawal.

[0017] A telescopic auxiliary ground support 9 is symmetrically provided at the front end of the frame. The auxiliary ground support is extended to support the ground or retracted to move away from the ground. The frame is also symmetrically provided with side supports 4. One end of the side support 4 is hinged to the lifting arm connecting seat 17. Side support cylinders 5 are symmetrically provided on the frame 1. The side support cylinders 5 extend rods to connect with the side supports 4. The side support cylinders 5 drive the side supports 4 to swing left and right around the hinge points, so that the side supports swing outward to support the tunnel wall or swing inward to retract. When the crawler tracks drive the frame to the working position, the bottom of the auxiliary ground support is against the ground and the side supports support the tunnel wall, ensuring the stability of the frame. When the anchor rods are withdrawn, the auxiliary ground support is away from the ground and the side supports are retracted, making it easier for the crawler tracks to move.

[0018] Tracks are used to drive the frame, adapting to the soft, uneven working conditions of the mine's tunnels. The frame is equipped with a boom and arm. The first rotary table drives the boom, arm, carriage, and carriage for 360° rotation in the Y-axis, while the second rotary table drives the carriage and carriage for 360° rotation in the X-axis. The boom and arm hydraulic cylinders raise the boom, arm, carriage, and carriage, driving the workhead to swing up and down, allowing it to operate within a 5m height range. The workhead's position can be fully adjusted to accommodate various drilling and anchoring positions.

[0019] The working head can be equipped with a drilling power head, chuck, anchor cutting head, anchor nut loading and unloading head and other working heads according to customer needs.

[0020] This application can drill holes and remove anchor rods at any working point at any angle, realize automatic anchor withdrawal, and improve work efficiency while ensuring safety.

[0021] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
