Description

Technical Field

[0001] The utility model relates to the technical field of stope mining, in particular to a stope filling material-chemical combined top support device. Background Art

[0002] Filling and top connection is an important factor affecting the filling effect of the mine. If the filling and top connection effect is poor, the mine roof will be exposed too much. When it reaches or exceeds the maximum exposure area allowed to maintain the stability of the roof, disasters such as roof collapse, surrounding rock spalling, and filling body collapse will follow, endangering the safety of operators. Most of the existing ore body support devices are temporarily assembled on site, which is not convenient to move, and it is very troublesome to install and disassemble.

[0003] In the prior art, a Chinese patent document with publication number CN112943334A is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: A ore body support device for coal mining includes a base, and a first support column is fixedly connected to the edges of the upper side of the base. A second support column is arranged inside the first support column, and a limiting hole is opened at the upper end of the first support column. A plurality of sockets are vertically opened on one side of the second support column. The first support column and the second support column are fixedly connected by a fixing rod, and one end of the fixing rod passes through the limiting hole and the socket.

[0004] In order to solve the problem that most of the existing ore body support devices are temporarily assembled on site, inconvenient to move, and troublesome to install and disassemble, the existing technology adopts the method of setting support columns and rollers. However, the adjustment distance of the support columns is limited by the sockets, and it is inconvenient to adjust the angle by manual rotation, which leads to the problem that the support range of the top support device is limited and the flexibility of angle adjustment is poor. Utility Model Content

[0005] The utility model aims to provide a stope filling materialization and chemical combination top connection support device to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A stope filling materialization and chemical joint top support device, comprising a mobile base, a positioning mechanism movably mounted on the bottom of the mobile base, a rotating mechanism fixedly mounted on the surface of the positioning mechanism, a top support mechanism fixedly mounted on the surface of the mobile base, and a limiting mechanism movably mounted between the mobile base and the top support mechanism;

[0008] The limiting mechanism comprises a servo motor, a threaded rod, a limiting rod and a contact plate.

[0009] A further improvement of the technical solution of the utility model is that the mobile base includes a supporting base plate, universal wheels are fixedly installed at the four ends of the bottom surface of the supporting base plate, a positioning rod is fixedly installed at the bottom surface of the supporting base plate, and a gear ring is fixedly installed at the middle part of the bottom surface of the supporting base plate. By setting the gear ring, it is convenient to cooperate with the rotating mechanism to rotate the supporting base plate and realize the adjustment of the horizontal angle.

[0010] A further improvement of the technical solution of the utility model is that: the positioning mechanism includes a connecting plate movably installed inside the supporting base plate, a hydraulic cylinder is fixedly installed on the surface of the connecting plate, and a supporting plate is fixedly installed on the bottom surface of the hydraulic cylinder. By setting up the positioning mechanism, after using the universal wheel to move the overall top support device, the hydraulic cylinder can be used to adjust the supporting plate to contact the ground so that the universal wheel is away from the ground to reduce the loss of pressure, and at the same time, the rotating mechanism can be cooperated to rotate the overall device.

[0011] A further improvement of the technical solution of the utility model lies in that: the rotating mechanism includes a rotating motor fixedly mounted on the surface of the supporting plate, an electric telescopic rod is fixedly mounted on the output end of the rotating motor, and a gear plate is fixedly mounted on one end of the electric telescopic rod. By setting up the rotating mechanism, when rotation adjustment is required, the electric telescopic rod can be driven by the rotating motor to drive the gear plate to rotate, thereby contacting the gear ring to drive the supporting base plate to rotate, and at the same time, the electric telescopic rod can be extended and retracted along with the hydraulic cylinder, so that the gear plate maintains contact with the gear ring.

[0012] A further improvement of the technical solution of the utility model is that the top support mechanism includes a telescopic cylinder fixedly installed on the surface of the supporting bottom plate, a telescopic rod is movably installed inside the telescopic cylinder, and a top plate is fixedly installed on the top surface of the telescopic rod. The telescopic rod is driven upward by the telescopic cylinder to drive the top plate to contact the filling material in the mining area for support.

[0013] A further improvement of the technical solution of the utility model lies in that: the servo motor is arranged between the supporting bottom plate and the connecting top plate, the threaded rod is fixedly installed at the output end of the servo motor, the limiting rod is movably installed at one end of the threaded rod, and the contact plate is fixedly installed on the surface of the limiting rod. By setting a limiting mechanism, the servo motor can be used to control the threaded rod to drive the limiting rod while the telescopic cylinder cooperates with the telescopic rod to adjust the connecting top plate for support, so that the contact plate contacts the supporting bottom plate and the connecting top plate, thereby realizing the limiting function.

[0014] A further improvement of the technical solution of the utility model is that a friction ball is arranged on the bottom surface of the positioning rod to increase the friction with the bottom surface, and the surface of the gear ring is movably connected to the surface of the gear plate.

[0015] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0016] 1. The utility model provides a joint top support device for filling material and chemical in a mining area. By setting a positioning mechanism, after the overall top support device is moved using universal wheels, the support plate can be adjusted by a hydraulic cylinder to contact the ground so that the universal wheels are away from the ground to reduce the loss of pressure, and the overall device can be rotated in conjunction with a rotating mechanism.

[0017] 2. The utility model provides a field filling materialization and chemical joint top support device. By setting a rotating mechanism, when rotation adjustment is needed, the electric telescopic rod can be driven by a rotating motor to drive the gear plate to rotate, thereby contacting the gear ring to drive the support bottom plate to rotate. At the same time, the electric telescopic rod can be extended and retracted along with the hydraulic cylinder, so that the gear plate maintains contact with the gear ring.

[0018] 3. The utility model provides a joint top support device for filling material and chemical in the mining area. By setting a limit mechanism, the telescopic cylinder cooperates with the telescopic rod to adjust the top plate for support, and at the same time, a servo motor is used to control the threaded rod to drive the limit rod, so that the resistance plate contacts the supporting bottom plate and the top plate, thereby realizing the limit function.
