Description

Technical Field

[0001] This utility model relates to a rapid muck removal device for vertical shafts, belonging to the field of vertical shaft construction technology. Background Technology

[0002] Before the initial lining is carried out after the excavation of the inner wall of the shaft is completed, the inner wall surface will be loosened due to the vibration of the construction environment. In order to meet the later construction requirements of the inner wall of the shaft, the loosened soil and stone need to be treated by spreading the slag.

[0003] The existing muck-laying technology, see Chinese Patent Publication No. CN114856603A, involves a steel wire rope fixedly connected to a trolley, on which a mini excavator is mounted. Because the end of the steel wire rope connecting to the trolley is in a free state, the mini excavator will swing and become unstable when working on the trolley, reducing the muck-laying efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rapid slag removal device for vertical shafts.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a rapid muck removal device for vertical shafts, comprising:

[0007] It can lift the top slab located within the vertical shaft;

[0008] The bottom of the slider is fixedly connected to the operating platform by a hanging rod, and there is an operating space between the top surface of the operating platform and the bottom surface of the slider for the operator to stand in.

[0009] A retractable push rod is installed on the side of the top plate, and a grab plate is fixed to the telescopic end of the push rod. The grab plate has grab nails.

[0010] The top plate has a passageway in the middle for personnel to enter and exit. A protective steel mesh plate is hinged to the top of the passageway. The protective steel mesh plate can be rotated to open or cover the passageway in the middle of the top plate. The operating platform is located below the top plate, and the top plate can intercept falling objects from above the shaft.

[0011] The top surface of the top plate is fixed with a hoisting cable; it also includes a pulley and a winch installed on the ground at the top of the shaft, with the hoisting cable wound around the pulley and connected to the winch.

[0012] The top plate is equipped with a slide rail, on which a slider is mounted that can only slide horizontally. The slider is pushed and pulled by a telescopic push-pull rod.

[0013] The telescopic end of the push-pull rod is fixed to the slider, and the fixed end of the push-pull rod is fixed to the bottom surface of the top plate.

[0014] A slag-laying boom is installed on the operating platform via a ball joint; the end of the slag-laying boom away from the inner wall of the shaft is located at the operating platform, and a slag-laying bag is fixed to the end of the slag-laying boom that is close to the inner wall of the shaft.

[0015] The beneficial effects of this utility model are as follows: when the top plate is raised to the corresponding height, the push rod, along with the grab plate, is locked onto the inner wall of the shaft, so that the top plate is stably placed inside the shaft. When the operator operates the muck-lowering arm on the operating platform, it will not swing freely, which can improve the muck-lowering efficiency of loose muck and rocks on the inner wall of the shaft. It solves the problem that the wire rope end of the existing technology will swing and become unstable, reducing the muck-lowering efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figure 1 As shown.

[0020] This application discloses a rapid muck removal device for vertical shafts, comprising:

[0021] A top plate 1 with a hoisting cable 11 is fixed on the top surface. The hoisting cable 11 is tied and fixed to the hoisting lugs on the top surface of the top plate 1. The top of the hoisting cable 11 is wound around a pulley 12 on the ground at the top of the shaft 2 and then connected to a winch 13. The winch 13 winds up and lifts or winds down and lowers the hoisting cable 11, so that the hoisting cable 11 carries the top plate 1 up and down in the shaft 2.

[0022] The top plate 1 is equipped with a slide rail 14. A slider 3 is mounted on the slide rail 14 and can only slide horizontally. The slider 3 is pushed and pulled by a telescopic push-pull rod 31. The telescopic end of the push-pull rod 31 is fixed to the slider 3, and the fixed end of the push-pull rod 31 is fixed to the bottom surface of the top plate 1.

[0023] The bottom of the slider 3 is fixedly connected to the operating platform 4 via a hanging rod 32. There is an operating space between the top surface of the operating platform 4 and the bottom surface of the slider 3 for the operator 5 to stand in. A slag-laying arm 6 is installed on the operating platform 4 via a ball hinge. The end of the slag-laying arm 6 away from the inner wall of the shaft 2 is located at the operating platform 4, and the end of the slag-laying arm 6 closer to the inner wall of the shaft 2 is fixed with a slag-laying bag 61. The operator 5 operates the slag-laying arm 6 on the operating platform 4 to make the slag-laying bag 61 lay down the loose slag and rocks in the shaft 2.

[0024] The top plate 1 is smaller than the vertical shaft 2. When the top plate 1 is inside the vertical shaft 2, there is a gap between the side of the top plate 1 and the vertical shaft 2. A telescopic push rod 21 is installed on the side of the top plate 1. A grab plate 22 is fixed to the telescopic end of the push rod 21. The grab plate 22 has grab nails that are stuck to the inner wall of the vertical shaft 2. The fixed end of the push rod 21 is fixed to the side of the top plate 1.

[0025] When the top plate 1 is raised and lowered to the corresponding height by the hoisting cable 11, the push rod 21, along with the grab plate 22, is locked onto the inner wall of the shaft 2, so that the top plate 1 is stably placed inside the shaft 2. When the operator 5 operates the muck-lowering arm 6 on the operating platform 4, it will not swing freely, which can improve the muck-lowering efficiency of loose muck and rocks on the inner wall of the shaft 2. This solves the problem that the wire rope end of the existing technology will swing and become unstable, reducing the muck-lowering efficiency.

[0026] The top plate 1 has a passageway in the middle for personnel to enter and exit. A protective steel mesh plate 23 is hinged to the top of the passageway. The protective steel mesh plate 23 can be rotated to open or cover the passageway in the middle of the top plate 1 to protect the operators 5 on the operating platform 4. The operating platform 4 is located below the top plate 1, and the top plate 1 can intercept falling objects from above the shaft 2.
