Technical Field

Background Art

[0002] With the development of the economy and the passage of time, cities are facing contradictions such as insufficient operation capacity of subways and congestion of underground spaces. These problems encourage people to develop and explore underground spaces, and become effective measures to relieve the bottleneck of urban development. Therefore, there is a need to expand existing structures.

[0003] The dock between the existing tunnel and the new tunnel is a reinforced concrete structure. By adopting the method of removing it by blasting, the stress of the existing tunnel is redistributed, so the existing tunnel is very likely to lose its stability. The method of cutting and removing with a high-pressure nozzle causes relatively small perturbation to the tunnel, but cutting and removing the reinforced concrete in the dock with a conventional high-pressure nozzle is a manual operation, which is time-consuming, and further safety problems arise, greatly reducing the removal efficiency of removing the existing structure by docking.

Embodiments for Carrying out the Invention

[0015] Referring to FIGS. 1-5, it is an embodiment according to the present invention.

[0016] The micro-perturbation dock removal device for the existing structure includes a moving trolley 1, on the surface of which a pushing rod 11 is fixedly connected, and a removal mechanism is installed on the surface of the moving trolley 1. The removal mechanism includes a water storage tank 2, which is fixedly connected to the surface of the moving trolley 1. A high-pressure plunger pump 21 is installed at the discharge port on the surface of the water storage tank 2. A high-pressure water pipe 22 is installed at the discharge port of the high-pressure plunger pump 21. A cutting gun head 23 is fixedly attached to the end of the high-pressure water pipe 22 away from the high-pressure plunger pump 21. The high-pressure plunger pump 21 transports the water in the water storage tank 2 to the cutting gun head 23 through the high-pressure water pipe 22. The cutting gun head 23 discharges water onto the cutting surface. Since the water contains an abrasive, the high-pressure water can cut the reinforced concrete at the dock part, thereby achieving the overall removal effect. An adjustment mechanism is installed on the surface of the moving trolley 1. The adjustment mechanism includes a fixed frame 3, which is fixedly connected to the surface of the moving trolley 1. A first motor 31 is fixedly connected to the surface of the fixed frame 3. A screw rod 32 is fixedly connected to the output shaft of the first motor 31. A nut 33 is screwed onto the surface of the screw rod 32. A connecting frame 34 is fixedly connected to the surface of the nut 33. A second motor 35 is fixedly connected to the surface of the connecting frame 34. A worm 36 is fixedly connected to the output shaft of the second motor 35. A rotating rod 37 is rotatably connected to the surface of the nut 33. A worm gear 38 is fixedly connected to the surface of the rotating rod 37. An adjustment rod 39 is fixedly connected to the surface of the rotating rod 37. The adjustment mechanism can adjust the cutting position of the cutting gun head 23 on the reinforced concrete at the dock part, thereby realizing the cutting of the reinforced concrete edge at the dock part, realizing the removal operation of the reinforced concrete at the dock part, saving the labor of the operator, improving the safety of use, and further improving the removal efficiency of removing the existing structure by docking.

[0017] Furthermore, a guide groove is formed on the surface of the fixed frame 3, the screw rod 32 rotates on the guide groove of the fixed frame 3, and the first motor 31 drives the screw rod 32 to rotate on the guide groove of the fixed frame 3 through the output shaft, so that the adjustment mechanism can adjust the position by adopting a machine.

[0018] Furthermore, the nut 33 is square in shape, and the screw rod 32 drives the nut 33 to slide up and down on the guide groove of the fixed frame 3 by rotation. When the screw rod 32 does not rotate, the screw rod 32 limits the position of the nut 33 on the fixed frame 3.

[0019] Furthermore, the nut 33 moves the second motor 35 and the worm 36 to move up and down synchronously through the connection frame 34, and the nut 33 moves the adjustment rod 39 and the worm gear 38 to move up and down synchronously through the rotating rod 37, so as to ensure the high consistency of the heights of the second motor 35, the worm 36, the worm gear 38 and the adjustment rod 39. At the same time, the up and down movement of the adjustment rod 39 can move the cutting gun head 23 to change the cutting height.

[0020] Furthermore, the connection frame 34 is in a "U" shape, the worm 36 rotates on the connection frame 34 through the output shaft of the second motor 35, and it is not necessary for the operator to rotate the worm 36. The worm 36 is directly below the worm gear 38.

[0021] Furthermore, the worm gear 38 and the adjustment rod 39 rotate on the nut 33 through the rotating rod 37. The cutting gun head 23 is fixedly connected to the end of the adjustment rod 39 away from the rotating rod 37. The adjustment rod 39 drives the cutting gun head 23 to rotate on the nut 33 by rotation. The cutting gun head 23 changes the cutting position by rotation and can cooperate with the up and down movement of the height, greatly improving the flexibility of the position adjustment of the cutting gun head 23.

[0022] Furthermore, between the worm gear 38 and the worm 36, they mesh with each other, and the worm 36 drives the worm gear 38 to rotate on the nut 33 by rotation. Between the worm gear 38 and the worm 36, they maintain a meshing state after termination, so that the worm 36 can drive the worm gear 38 to rotate on the nut 33.

[0023] Operating principle: When docking an existing tunnel and a new tunnel, remove the reinforced concrete between the existing tunnel and the new tunnel, push the moving trolley 1 to one side of the reinforced concrete through the push rod 11 on the new tunnel, drive the screw rod 32 to rotate through the output shaft of the first motor 31, and the screw rod 32 drives the nut 33 to slide up and down on the guide groove of the fixed frame 3 by rotation. The nut 33 moves the cutting gun head 23 up and down through the adjusting rod 39, thereby changing the cutting height of the adjusting rod 39. At the same time, move the worm 36 to rotate through the output shaft of the second motor 35. The worm 36 drives the worm gear 38 to rotate by rotation. The worm gear 38 moves the adjusting rod 39 to rotate through the rotating rod 37. The adjusting rod 39 changes the cutting position of the cutting gun head 23 by rotation, and cooperates with the movement of the moving trolley 1 on the new tunnel, so that the edge of the reinforced concrete can be cut and removed flexibly. Thereby, the operation of removing minute perturbations to the reinforced concrete at the docking part is realized, saving the labor of workers, improving the safety of use, and further improving the removal efficiency of docking and removing the existing structure.
