Technical Field

[0001] This utility model relates to the field of tunnel support technology, specifically a mine tunnel support device with water drainage function. Background Technology

[0002] Mining roadways are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrian access, and preparation for mining operations. Vertical roadways have their long axis perpendicular to the horizontal plane, such as vertical shafts, and are directly connected to the surface. The main shaft is used to hoist ore, and the auxiliary shaft is used to hoist waste rock, lower equipment, and raise and lower personnel. Blind vertical shafts are not directly connected to the surface, and there are also special ore chutes. Horizontal roadways have their long axis approximately parallel to the horizontal plane. Adits are directly connected to the surface and include main adits and auxiliary adits. Stone gates are not directly connected to the surface, and their long axis is obliquely or perpendicular to the strike of the ore body. Horizontal roadways are not directly connected to the surface, and their long axis is parallel to the strike of the ore body. They can be divided into intra-vein horizontal roadways and extra-vein horizontal roadways.

[0003] Tunnel support devices are equipment or structures used to maintain the stability of the surrounding rock in tunnels and prevent its deformation and collapse. Most existing tunnel support devices only have basic support functions. However, during the tunnel excavation process, water may accumulate and cannot be drained quickly, which can easily affect the normal passage inside the tunnel. Utility Model Content

[0004] The purpose of this utility model is to provide a mine roadway support device with water drainage function to solve the problem mentioned in the background art that water may accumulate in the roadway during the excavation process and cannot be drained quickly, which may affect the normal passage inside the roadway.

The buffer mechanism uses the compression block to press down, thereby pushing two compression rollers to separate, while the compression rollers drive the linkage arm to rotate and compress the spring, thus providing buffering.

[0006] Preferably, the surface of the bottom support frame is provided with a positioning cone, the lower end of the suction pipe is flush with the lower surface of the bottom support frame, and the two bottom support frames are symmetrically arranged.

[0007] By adopting the above technical solution, the lower end of the suction pipe is flush with the lower surface of the bottom support frame, which can get as close as possible to the water at the bottom of the tunnel, avoiding the inability to suction the water at low levels due to the pipe being suspended, and ensuring more thorough drainage of the water.

[0008] Preferably, the width of the lower positioning frame is the same as the width of the upper positioning block, the upper surface of the upper positioning block is arc-shaped, the limiting slide post and the limiting slot form a sliding connection, and a spring connects the limiting slide post and the limiting slot.

[0009] Using the above technical solution, the sliding connection between the limiting slide column and the limiting slot provides guidance for the relative movement of the upper and lower structures, preventing deviation. The spring between the two can further absorb the impact load at the top of the roadway, alleviating the damage to the device caused by instantaneous pressure.

[0010] Preferably, the compression block is horizontally arranged, the lower end side surface of the compression block is inclined, and the buffer groove is correspondingly arranged with the compression block.

[0011] By adopting the above technical solution, the horizontal setting of the compression block can ensure that the pressure is transmitted vertically downward to the buffer mechanism, avoiding the force transmission offset caused by the tilt setting, and ensuring reliable buffering effect.

[0012] Preferably, the buffer mechanism includes a mounting post, which is fixedly connected to the bottom surface of the buffer groove. A linkage rotating arm is mounted on the surface of the mounting post, and a compression roller is installed between the two linkage rotating arms.

[0013] By adopting the above technical solution, the mounting column is fixed to the bottom surface of the buffer groove, providing stable support for the entire buffer mechanism and avoiding functional failure due to structural loosening during the buffering process.

[0014] Preferably, the mounting support and the linkage arm are rotatably connected, the linkage arm is designed to be inclined, and a spring is connected between the upper side surface of the linkage arm and the bottom surface of the buffer groove.

[0015] By adopting the above technical solution, the rotating connection between the mounting column and the linkage arm is installed, allowing the arm to rotate flexibly around the column, providing sufficient space for cushioning action, and ensuring that pressure can be smoothly converted into the elastic potential energy of the spring.

[0016] Preferably, the extrusion roller is disposed on the upper end of the linkage rotating arm, the extrusion roller and the linkage rotating arm are rotatably connected, and the extrusion roller is a cylinder made of rubber.

[0017] By adopting the above technical solution, the rotational connection between the extrusion roller and the linkage arm can convert the sliding friction between the extrusion block and the roller into rolling friction, reduce frictional resistance, make the buffering action smoother, and avoid local wear caused by jamming.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the mine roadway support device with water drainage function:

[0019] 1. This device effectively solves the problem of water accumulation in roadways by integrating pumping and support functions. The pumping pump, together with the suction pipe and the drainage pipe, can quickly pump out the water accumulated at the bottom, preventing water accumulation from affecting passage and work safety, and improving the adaptability of the roadway environment.

[0020] 2. The support structure is designed to fit the characteristics of the roadway. The arc-shaped surface of the upper limit block is adapted to the contour of the roadway top. The support cylinder can flexibly adjust the support height. The sliding cooperation between the limit sliding column and the limit slot ensures that the support process is stable and without deviation, significantly enhancing the support effect of the surrounding rock.

[0021] 3. The buffer mechanism achieves long-term durability through multiple shock absorptions. The squeezing block pushes the squeezing roller to drive the linkage arm to rotate, and the spring compression absorbs the impact energy, reducing the damage of roadway vibration to the device and greatly extending the service life of the equipment.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a mine roadway support device with water drainage, including a bottom support frame 1, a drainage pump 2, a suction pipe 3, a drainage pipe 4, a support cylinder 5, a lower positioning frame 6, a limiting sliding column 7, an upper positioning block 8, a limiting slot 9, a squeezing block 10, a buffer groove 11, a mounting column 12, a linkage rotating arm 13, and a squeezing roller 14. The drainage pump 2 is fixedly connected to the upper side surface of the bottom support frame 1, and the suction pipe 3 is fixedly connected to the lower end of the drainage pump 2. A positioning cone is provided on the surface of the bottom support frame 1, and the lower end of the suction pipe 3 is flush with the lower surface of the bottom support frame 1. Two bottom support frames 1 are symmetrically arranged and fixed to the roadway ground by the surface positioning cones. The symmetrical double-frame structure enhances stability. After the drainage pump 2 is started, the suction pipe 3 sucks in the water and discharges it from the roadway through the drainage pipe 4.

[0031] A drainage pipe 4 is installed through the surface of the pump 2. A support cylinder 5 is fixedly connected to the upper surface of the bottom support frame 1. A lower positioning frame 6 is fixedly connected to the output end of the support cylinder 5. A limit sliding column 7 is fixedly connected to the upper surface of the lower positioning frame 6. The width of the lower positioning frame 6 is the same as the width of the upper limit block 8. The upper surface of the upper limit block 8 is arc-shaped. The limit sliding column 7 and the limit slot 9 form a sliding connection. A spring is connected between the limit sliding column 7 and the limit slot 9. The support cylinder 5 outputs power to push the lower positioning frame 6 to rise. The upper limit block 8 moves up until it fits against the top of the tunnel. The limit sliding column 7 slides in the limit slot 9. The spring in the slot limits the offset and ensures the stability of the rising trajectory.

[0032] An upper limit block 8 is provided above the lower positioning frame 6. A limit slot 9 is provided on the lower surface of the upper limit block 8. A pressing block 10 is fixedly connected to the lower surface of the upper limit block 8. A buffer groove 11 is provided on the upper surface of the lower positioning frame 6. The pressing block 10 is horizontally set. The lower end side surface of the pressing block 10 is designed to be inclined. The buffer groove 11 is set correspondingly to the pressing block 10. The buffer mechanism includes a mounting column 12. The mounting column 12 is fixedly connected to the bottom surface of the buffer groove 11. A linkage rotating arm 13 is installed on the surface of the mounting column 12. A pressing roller 14 is installed between the two linkage rotating arms 13. The pressure at the top of the tunnel acts on the upper limit block 8, causing it to press down and drive the pressing block 10 to insert into the buffer groove 11. The inclined lower end of the pressing block 10 pushes the pressing rollers 14 on both sides to separate outward.

[0033] A buffer mechanism is provided on the bottom surface of the buffer groove 11. The mechanism pushes the two pressure rollers 14 apart by pressing down the pressure block 10. At the same time, the pressure rollers 14 drive the linkage arm 13 to rotate and compress the spring to buffer the impact. The mounting column 12 and the linkage arm 13 are rotatably connected. The linkage arm 13 is designed with an inclination, and a spring is connected between the upper side surface of the linkage arm 13 and the bottom surface of the buffer groove 11. The pressure rollers 14 are located on the upper end of the linkage arm 13 and are rotatably connected to the linkage arm 13. The pressure rollers 14 are cylindrical rubber cylinders. The pressure rollers 14 drive the linkage arm 13 to rotate around the mounting column 12. The arm compresses the spring connected to the buffer groove 11, converting the impact energy into elastic potential energy. After the pressure is removed, the spring rebounds and drives the linkage arm 13 and the pressure rollers 14 to reset.

[0034] Working principle: When using this mine roadway support device with water drainage, the bottom support frame 1 is fixed to the roadway ground by the positioning cone. The symmetrical double frame ensures overall stability. After the drainage pump 2 is started, the water is pumped out through the suction pipe 3 and discharged through the drainage pipe 4 to solve the water accumulation problem. During the support adjustment stage, the support cylinder 5 pushes the positioning frame 6 to rise, and the upper limit block 8 moves up to fit the top of the roadway. The limit sliding column 7 slides in the limit slot 9 and cooperates with the spring to prevent deviation. When pressure is applied to the top of the roadway, the upper limit block 8 drives the squeezing block 10 to insert into the buffer groove 11. Its inclined lower end pushes the two squeezing rollers 14 to separate. The rollers drive the linkage arm 13 to rotate around the mounting support 12. The compression spring absorbs the impact energy. After the pressure disappears, the spring rebounds and resets the linkage arm 13 and the roller, increasing the overall practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
