The lifting platform 22 moving upward drives the stepping platform 24 installed thereon to move, and adjusts the height of the operator standing on the stepping platform 24, thereby avoiding the situation where the operator needs to adjust his or her posture and height to complete special actions such as anchor clamping, anchor net installation and anchor agent filling due to the non-adjustable height of the standing platform on the left and right sides of the anchor drill, thereby reducing the labor intensity of the work and facilitating the support operations of auxiliary anchors and top anchors.

[0030] In one embodiment, since the double-top anchor assembly 4 is installed on one side of the lifting platform 22 through the mounting plate 28, when performing anchor support operations, the hydraulic cylinder 23 can be used to drive the hydraulic extension rod at its output end to extend, and push the lifting platform 22 installed thereon to move upward. The lifting platform 22 moving upward drives the double-top anchor assembly 4 installed on one side of it through the mounting plate 28 to move, and the position of the double-top anchor assembly 4 can be adjusted, making the double-top anchor assembly 4 suitable for operations in tunnels of different heights, thereby improving the applicability of the anchor mining machine.

[0032] In one embodiment, when adjusting the height of the lifting platform 22, the lifting platform 22 is displaced upward under the action of the hydraulic cylinder 23 and the hydraulic extension rod, and pulls the limit link 33 installed and rotated at its bottom to displace, and then the displaced limit link 33 pulls the first link 32 and the second link 34 rotated thereon through the hinge shaft 35 to displace, so that the limit link 33, the first link 32, the second link 34 and the base 31 form a quadrilateral above the mounting platform 21 to assist in supporting the lifting platform 22, preventing the lifting platform 22 from falling, and avoiding the situation where the lifting platform 22 fails due to the failure of the hydraulic cylinder 23 on one side of the mounting platform 21, causing the operator to fall, thereby playing a role of safety protection and improving the safety of the lifting platform 2.

[0033] In one embodiment, when the auxiliary support mechanism 3 is used to support the lifting platform 22, its position can be limited by the limit link 33 installed at the bottom of the lifting platform 22 to prevent the lifting platform 22 from tilting or shaking on the hydraulic extension rods at the output ends of the hydraulic cylinders 23 on both sides, thereby avoiding the trouble of unstable standing of the operators due to the tilting or shaking of the lifting platform 22, improving the stability of the lifting platform 22 and having strong practicality.

[0034] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, slide seats 221 are provided at both ends of the top of the lifting platform 22, and guide rails 241 are provided at the bottom of the treading platform 24 at positions corresponding to the slide seats 221. The guide rails 241 are slidably installed inside the slide seats 221. In addition, a horizontal push cylinder 25 is provided at the top of the lifting platform 22 between the two slide seats 221, and a horizontal push extension rod is provided at the output end of the horizontal push cylinder 25. A connecting seat 242 is provided at the middle position of the bottom of the treading platform 24, and the horizontal push extension rod is installed inside the connecting seat 242.

[0035] In one embodiment, when adjusting the position of the stepping platform 24, the horizontal push extension rod at its output end can be driven to extend through the horizontal push cylinder 25, and then the horizontal push extension rod installed at the bottom of the stepping platform 24 through the connecting seat 242 pushes it to move, so that the stepping platform 24 can move toward the outside of the anchor mining machine body through the cooperation of the guide slide rail 241 and the slide seat 221, adjust the position of the stepping platform 24 and the operator standing on it, expand the operating space of the operator standing on the stepping platform 24, shorten the distance between the operator and the two side arms, which is beneficial to the implementation of the anchor support operation and improves the operation efficiency.

[0036] In one embodiment, since guardrails 26 are provided on both sides of the stepping platform 24, when the stepping platform 24 is in use, the guardrails 26 can protect the operator standing on the stepping platform 24 to prevent the operator from falling from the stepping platform 24, thereby improving the safety of the operation.

[0037] Combination Figure 1 , Figure 4 and Figure 7 As shown, the escalator 27 is composed of an upper guard ladder 271 and a lower guard ladder 272, wherein the lower guard ladder 272 is slidably installed inside the upper guard ladder 271 and extends to the bottom thereof, and a fixing sleeve 273 is provided at one end of the lower guard ladder 272 located inside the upper guard ladder 271, and the fixing sleeve 273 is slidably installed on the end surface of the upper guard ladder 271, and a locking bolt 274 is provided on the end surface of the fixing sleeve 273, and a plurality of adjusting screw holes 275 are evenly arranged on the end surface of the upper guard ladder 271, and the locking bolt 274 passes through the fixing sleeve 273 and is threadedly installed inside the adjusting screw hole 275.

Then, the locking bolt 274 is screwed to fix the locking bolt 274 inside the adjusting screw hole 275 to limit the position of the fixing sleeve 273, thereby completing the adjustment of the ladder 27, which is suitable for workers of different heights to climb. Moreover, the workers can also climb away from the stepping platform 24 via the ladder 27, thereby avoiding the situation where it is inconvenient for the workers to get off the stepping platform 24 due to the high position of the stepping platform 24, and facilitating the use of the workers.

[0039] In one embodiment, when the escalator 27 is not in use, the lower guard ladder 272 can be completely stored into the upper guard ladder 271 to reduce the volume of the escalator 27, avoid the escalator 27 occupying a large space, and facilitate the storage of the escalator 27.

At the same time, the limiting link 33 in displacement pulls the first link 32 and the second link 34 rotated thereon through the hinge shaft 35 to displace, so that the limiting link 33, the first link 32, the second link 34 and the base 31 form a quadrilateral auxiliary support lifting platform 22 above the mounting platform 21 to prevent the lifting platform 22 from being lifted. The lifting platform 22 is stopped from falling, and the situation that the lifting platform 22 falls and the operator falls due to the failure of the hydraulic cylinder 23 on one side of the mounting platform 21 is avoided, which plays a role of safety protection and improves the safety of the lifting platform 2. In addition, the horizontal push extension rod at its output end can be driven to extend through the horizontal push cylinder 25, and then the horizontal push extension rod installed at the bottom of the stepping platform 24 through the connecting seat 242 pushes it to move, so that the stepping platform 24 can be moved to the outside of the anchor mining machine body through the cooperation of the guide slide rail 241 and the slide seat 221, and the position of the stepping platform 24 and the operator standing on it is adjusted, the operating space of the operator standing on the stepping platform 24 is expanded, and the distance between the operator and the two side parts is shortened, which is conducive to the anchor support operation and improves the operation efficiency.
