[0021] Please see Figure 1-5 One embodiment provided by this utility model:
[0022] A lining trolley traction device with a steep gradient includes a traction vehicle body 11. The bottom of the traction vehicle body 11 is equipped with pulleys, allowing it to slide and move inside the tunnel. A tunnel guide rail 1 is provided on one side of the traction vehicle body 11. An anchoring mechanism is provided at the bottom of the traction vehicle body 11. A movable base 12 is slidably connected to the surface of the tunnel guide rail 1. A lining trolley body 13 is mounted on the surface of the movable base 12. A traction mechanism is mounted on the surface of the traction vehicle body 11. The traction mechanism includes a high-power motor 2, which is fixedly connected to the surface of the traction vehicle body 11. A rotating rod 21 is fixedly connected to the surface of the high-power motor 2. A traction wheel 22 is fixedly connected to the surface of the rotating rod 21. A main traction rope 23 is fixedly connected to the surface of the traction wheel 22. A secondary traction rope 24 is fixedly connected to the surface of the main traction rope 23. The end of the secondary traction rope 24 away from the main traction rope 23 is hooked and connected to the surface of the lining trolley body 13. A ratchet column 25 is fixedly connected to the surface of the traction vehicle body 11. A support frame 26 is fixedly connected to the surface of the traction vehicle body 11. A ratchet plate 27 is rotatably connected to the surface of the support frame 26. A return torsion spring 28 is fixedly connected to the surface of the ratchet plate 27. The end of the return torsion spring 28 away from the ratchet plate 27 is fixedly connected to the surface of the support frame 26. A limit plate 29 is fixedly installed on the surface of the support frame 26. The traction mechanism needs to fix the traction vehicle body 11 to the bottom of the tunnel through the anchoring mechanism. Then, the traction mechanism drives the traction wheel 22 to rotate. The traction wheel 22 pulls the lining trolley body 13 through the traction main rope 23 and the traction auxiliary rope 24. During the traction process, the ratchet column 25, support frame 26, ratchet plate 27, return torsion spring 28 and limit plate 29 cooperate with each other to prevent the rotating rod 21 from rotating in the opposite direction, thereby preventing the lining trolley body 13 from sliding down due to the reverse rotation of the rotating rod 21, thus improving the safety of the traction device.
[0023] Furthermore, the anchoring mechanism includes a guide rod 3, which is fixedly connected to the bottom of the tractor body 11. A movable plate 31 is slidably connected to the surface of the guide rod 3, and a locking plate 33 is fixedly connected to the surface of the movable plate 31. A bidirectional electric push rod 32 is fixedly connected to the bottom of the tractor body 11, and the piston rod of the bidirectional electric push rod 32 is fixedly connected to the surface of the movable plate 31. An anchoring base 34 is inserted into the surface of the locking plate 33, and an expansion bolt 35 is provided on the surface of the anchoring base 34. The anchoring mechanism uses the expansion bolt 35 to... Anchor base 34 is restricted at the bottom of the tunnel, and then clamped on anchor base 34 by locking plate 33. At this time, anchor base 34 restricts the position of traction vehicle 11 inside the tunnel by locking plate 33 and moving plate 31, thereby restricting the position of traction vehicle 11 in the tunnel, which facilitates traction operation of traction device. Furthermore, traction vehicle 11 can change its position in the tunnel by sliding, which facilitates switching the position of traction vehicle 11 for traction, thereby improving the continuity of traction device pulling lining trolley body 13 to slide inside the tunnel.
[0024] Furthermore, the high-power motor 2 serves as the power source for the entire traction mechanism. Its output shaft is connected to the rotating rod 21 via a coupling. The high-power motor 2 drives the rotating rod 21 to rotate via its output shaft. The rotating rod 21 is made of high-strength alloy steel. Two sets of traction wheels 22 are provided, and the rotating rod 21 drives the two sets of traction wheels 22 to rotate synchronously. The traction wheels 22 wind around the traction main rope 23 by rotating. The central axis of the two sets of traction wheels 22 coincides with the central axis of the rotating rod 21, thereby ensuring their synchronicity during rotation.
[0025] Furthermore, multiple sets of auxiliary traction ropes 24 are provided to ensure the stability of traction on the lining trolley body 13. The main traction rope 23 pulls the lining trolley body 13 through multiple sets of auxiliary traction ropes 24 to slide on the tunnel guide rail 1 via the movable base 12, and the rotating rod 21 drives the ratchet column 25 to rotate synchronously.
[0026] Furthermore, the limiting plate 29 is connected to one side of the ratchet plate 27, and the limiting plate 29 restricts the ratchet plate 27 from continuing to rotate in the direction of the limiting plate 29. During the rotation of the ratchet column 25, the ratchet plate 27 is driven to rotate counterclockwise, and the return torsion spring 28 causes the ratchet plate 27 to rotate clockwise until it contacts the surface of the limiting plate 29. The ratchet plate 27 is rotatably connected to the support frame 26 through a pin. The pin is made of high-strength alloy steel, and the return torsion spring 28 is made of high-strength spring steel, which has good elasticity and fatigue performance. When one ratchet tooth of the ratchet column 25 passes the ratchet plate 27, the return torsion spring 28 causes the ratchet plate 27 to rotate clockwise until it contacts the surface of the limiting plate 29. The function of the limiting plate 29 is to restrict the ratchet plate 27 from continuing to rotate in its direction, ensuring that the ratchet plate 27 is in the right position so that it can engage with the ratchet tooth of the ratchet column 25 in time when the next ratchet tooth arrives.
[0027] Furthermore, the guide rod 3 is provided in two sets. The movable plate 31 slides at the bottom of the traction vehicle body 11 through the guide rod 3. The movable plate 31 drives the bidirectional electric push rod 32 to slide synchronously. The bidirectional electric push rod 32 drives the movable plate 31 to slide at the bottom of the traction vehicle body 11 through the piston rod. The movable plate 31 is provided in two sets, and the sliding directions of the two sets of movable plates 31 are opposite, which enables the locking plate 33 to clamp the anchor base 34 at the same time, thereby improving the stability and reliability of the anchoring.
[0028] Furthermore, limiting holes are opened on both sides of the anchor base 34, and the locking plate 33 is inserted into the limiting holes of the anchor base 34. The end of the locking plate 33 away from the moving plate 31 is in the shape of an isosceles trapezoid. During the insertion process, the isosceles trapezoidal end of the locking plate 33 will gradually contact the inner wall of the limiting hole. Through the gradually increasing friction and extrusion force, the locking plate 33 is firmly inserted into the limiting hole. The surface of the anchor base 34 is provided with installation holes. The expansion bolt 35 is installed through the installation holes of the anchor base 34. Before installing the expansion bolt 35, it is necessary to drill a hole at the bottom of the tunnel that matches the specification of the expansion bolt 35. The depth and diameter of the drilling hole are determined according to the size of the expansion bolt 35 and the geological conditions at the bottom of the tunnel. After inserting the expansion bolt 35 into the drilling hole, the bolt is expanded by tightening the nut and tightly bonded to the rock or concrete at the bottom of the tunnel. Multiple sets of expansion bolts 35 are provided to firmly fix the anchor base 34 at the bottom of the tunnel and ensure the normal operation of the traction device.
[0029] Working principle: Before the traction operation begins, the traction vehicle body 11 needs to be firmly fixed to the bottom of the tunnel using the anchoring mechanism. After fixing, the high-power motor 2 is started, and its output shaft drives the rotating rod 21 to rotate. Since the rotating rod 21 is fixedly connected to two sets of traction wheels 22, the rotating rod 21 will drive the two sets of traction wheels 22 to rotate synchronously. The rope grooves on the outer circumference of the traction wheels 22 will gradually wind the main traction rope 23. The multiple sets of auxiliary traction ropes 24 connected to the main traction rope 23 will then be stressed. The auxiliary traction ropes 24 are connected to the lining trolley body 13 through hooks, thereby driving the lining trolley body 13 to slide on the tunnel guide rail 1 via the movable base 12. During the entire traction process, the rotating rod 21 drives the ratchet... The ratchet column 25 rotates synchronously. When the rotating rod 21 rotates forward, the ratchet teeth of the ratchet column 25 push the ratchet plate 27 to rotate counterclockwise, causing the return spring 28 to deform. After a ratchet tooth passes the ratchet plate 27, the elastic force of the return spring 28 causes the ratchet plate 27 to rotate clockwise until it contacts the limiting plate 29, which facilitates the subsequent rotation of the ratchet column 25. The limiting plate 29 restricts the ratchet plate 27 from continuing to rotate, ensuring that it is in the correct position. If the rotating rod 21 shows a tendency to rotate in the opposite direction, the ratchet plate 27 will be stuck between the ratchet teeth of the ratchet column 25, preventing the rotating rod 21 from reversing and avoiding the lining trolley body 13 from sliding down due to the reversal of the rotating rod 21, which greatly improves the safety of the traction device.
[0030] Select a suitable location at the bottom of the tunnel and drill installation holes that match the expansion bolts 35. Place the anchor base 34 in place, aligning the installation holes. Then, insert multiple sets of expansion bolts 35 through the installation holes and screw them into the drilled holes at the bottom of the tunnel. Tighten the nuts to open the expansion tubes at the tails of the expansion bolts 35, tightly pressing them against the borehole wall, thereby firmly securing the anchor base 34 at the bottom of the tunnel. When it is necessary to fix the tractor body 11, activate the bidirectional electric push rod 32. Its piston rod pushes two sets of moving plates 31 to slide in opposite directions along the guide rod 3. The locking plate 33 connected to the moving plate 31 moves with the moving plate 31. Since the end of the locking plate 33 is an isosceles trapezoid, it can smoothly... The traction vehicle body 11 is inserted into the limiting holes on both sides of the anchoring base 34. At this time, the anchoring base 34 restricts the position of the traction vehicle body 11 inside the tunnel through the locking plate 33 and the moving plate 31, fixing the traction vehicle body 11 in a specific position in the tunnel and creating stable conditions for the traction operation of the traction device. When it is necessary to change the position of the traction vehicle body 11, the bidirectional electric push rod 32 is activated in the reverse direction, so that the locking plate 33 is pulled out from the limiting hole, and the traction vehicle body 11 can slide freely to a new position inside the tunnel. The fixing steps are repeated again, which facilitates the traction vehicle body 11 to switch positions for traction and improves the continuity of the traction device pulling the lining trolley body 13 to slide inside the tunnel.
