Technical Field

[0001] The utility model relates to the field of mining engineering, in particular to a temporary supporting device for a tunnel. Background Art

[0002] Underground mining is an important means of resource extraction. It aims to excavate ores or minerals from underground rock formations to serve multiple fields such as industry and construction. The mining process is complex, covering geological exploration, mine planning, tunneling, support and reinforcement, ore mining and transportation, etc. Among them, a large number of tunnels need to be excavated underground, so tunnel support devices need to be installed to slow down the movement of surrounding rock, maintain tunnel stability, prevent surrounding rock from dispersing and falling, and ensure the safety and efficiency of mining operations.

[0003] However, in the prior art, the support device is only fixed at a single point by an anchor rod at the lower end during use, which results in poor stability of the device and thus affects safety during use. Utility Model Content

[0004] The purpose of the present invention is to provide a temporary support device for a tunnel to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a temporary support device for a tunnel, comprising a support plate, wherein the upper end of the support plate is fixedly connected to a connecting plate, a threaded hole is formed inside the connecting plate, a guide hole is formed inside the connecting plate near the threaded hole, a guide rod is slidably connected to the inside of the guide hole, a movable plate is fixedly connected to one side of the guide rod, and an anchor rod is provided inside the movable plate;

[0006] A clamping ring is fixedly connected to the right side of the movable plate near the guide rod, a clamping ring is movably connected inside the clamping ring, a screw rod is fixedly connected to the right side of the clamping ring, the lower end of the support plate is fixedly connected to the base, and the lower end of the base is fixedly connected to the connecting rod.

[0007] Preferably, the upper end of the support plate is fixedly connected to a short rod, the upper end of the short rod is fixedly connected to a fixed seat, a rotation groove is opened on one side of the fixed seat, a limiting rod is provided inside the rotation groove, a rotating rod is sleeved on the outside of the limiting rod, the upper end of the rotating rod is fixedly connected to a threaded column, and a fixing ring is provided on the outside of the threaded column.

[0009] Preferably, the screw rod is movably connected to the movable plate through a clamping ring and a clamping ring.

[0010] Preferably, the rotating rod is movably connected to the fixing seat via a limiting rod.

[0011] Preferably, the number of the mounting blocks is two groups, and they are symmetrically arranged about the center line of the support beam.

[0012] By adopting the above technical solution, by rotating the screw rod, under the action of the threaded hole inside the support plate, the movable plate moves to one side and fits tightly against the side wall of the tunnel. At this time, the staff can insert the anchor rod in the movable plate into the side wall, thereby achieving double limiting of the movable plate, that is, completing the secondary fixation of the device. Similarly, when dismantling, it is only necessary to rotate the screw rod in the opposite direction to release the limit on the movable plate. During the movement of the movable plate, the guide rod slides inside the guide hole.

The position of the movable plate can be adjusted by means of components such as the screw rod, the retaining ring, the retaining ring, the support plate, and the guide rod, so that the two sides of the device can be fixed, which greatly improves its stability and safety during use.

[0013] By adopting the above technical solution, by rotating the fixing ring, the internal thread of the fixing ring cooperates with the external thread of the threaded column, the fixing ring moves away from the mounting plate, and the rotating rod can drive the threaded column to rotate out of the rotating groove, thereby realizing the separation of the mounting block and the fixing seat, and completing the disassembly of the support beam. Similarly, during installation, it is only necessary to press the bottom of the mounting plate against the fixing seat and rotate the rotating rod and the fixing ring. The rotating rod will rotate outside the limiting rod into the rotating groove, and the fixing ring will move in the opposite direction and press against one side of the mounting block to complete the installation of the support beam. The support beam can be loaded and unloaded through components such as the fixing seat, limiting rod, rotating rod, threaded column, and fixing ring, and can be flexibly replaced according to usage requirements, while also reducing the difficulty of replacement.

[0023] Specifically, by rotating the screw rod 10, under the action of the internal threaded hole 3 of the support plate 1, the movable plate 6 moves to one side and fits tightly against the side wall of the tunnel. At this time, the staff can insert the anchor rod 7 in the movable plate 6 into the side wall, thereby achieving double limiting of the movable plate 6, that is, completing the secondary fixation of the device. Similarly, when dismantling, it is only necessary to rotate the screw rod 10 in the opposite direction to release the limiting of the movable plate 6. During the movement of the movable plate 6, the guide rod 5 slides inside the guide hole 4. With the cooperation of the guide rod 5 and the guide hole 4, the stability of the movable plate 6 during movement can be increased. The position of the movable plate 6 can be adjusted by means of components such as the screw rod 10, the retaining ring 9, the retaining ring 8, the support plate 1, and the guide rod 5, thereby achieving fixation on both sides of the device, greatly improving its stability and safety during use.

[0024] Example 2

[0025] See also Figure 1-Figure 5The utility model provides a technical solution: a temporary support device for a tunnel, the upper end of the support plate 1 is fixedly connected to a short rod 13, the upper end of the short rod 13 is fixedly connected to a fixed seat 14, a rotation groove 15 is opened on one side of the fixed seat 14, a limiting rod 16 is arranged inside the rotation groove 15, and a rotating rod 17 is sleeved on the outside of the limiting rod 16, the upper end of the rotating rod 17 is fixedly connected to a threaded column 18, and a fixing ring 19 is arranged on the outside of the threaded column 18, and a mounting block 20 is provided at the upper end of the fixed seat 14, a card slot 21 is opened inside the mounting block 20, the upper end of the mounting block 20 is fixedly connected to a support rod 22, and the upper end of the support rod 22 is fixedly connected to a supporting beam 23, the rotating rod 17 is movably connected to the fixed seat 14 through the limiting rod 16, and the number of the mounting blocks 20 is two groups, and they are symmetrically arranged about the center line of the support beam 23.

[0026] Specifically, by rotating the fixing ring 19, the internal thread of the fixing ring cooperates with the external thread of the threaded column 18, and the fixing ring moves away from the mounting plate, and the rotating rod 17 can drive the threaded column 18 to rotate out of the rotating groove 15, thereby separating the mounting block 20 and the fixing seat 14, and completing the disassembly of the support beam 23. Similarly, during installation, it is only necessary to press the bottom of the mounting plate against the fixing seat 14 and rotate the rotating rod 17 and the fixing ring 19. The rotating rod 17 will rotate outside the limiting rod 16 into the rotating groove 15, and the fixing ring 19 will move in the opposite direction and press against one side of the mounting block 20 to complete the installation of the support beam 23. The support beam 23 can be loaded and unloaded through components such as the fixing seat 14, the limiting rod 16, the rotating rod 17, the threaded column 18, and the fixing ring 19, so that it can be flexibly replaced according to usage requirements, while also reducing the difficulty of replacement.

[0027] Working principle: When the temporary support device for the tunnel is in use, the connecting rod 12 at the lower end of the base 11 is first used to achieve preliminary stable installation. Subsequently, the anchor rods 7 on both sides of the device are used for secondary reinforcement to ensure that it is firmly and reliably fixed in the tunnel. The specific operation is to rotate the screw rod 10. Under the action of the threaded hole 3 inside the support plate 1, the movable plate 6 moves to one side and fits tightly against the side wall of the tunnel. At this time, the staff can insert the anchor rod 7 in the movable plate 6 into the side wall, thereby achieving double limit of the movable plate 6, that is, completing the secondary fixation of the device. Similarly, when dismantling, only the screw rod 10 needs to be rotated in the opposite direction to release the limit of the movable plate 6. During the movement of the movable plate 6, the guide rod 5 slides inside the guide hole 4. With the cooperation of the guide rod 5 and the guide hole 4, the stability of the movable plate 6 during movement can be increased. The position of the movable plate 6 can be adjusted by the screw rod 10, the clamping ring 9, the clamping ring 8, the support plate 1, the guide rod 5 and other components. The position can be adjusted, thereby achieving the fixation of both sides of the device, greatly improving its stability and safety during use. When it is necessary to replace the support beam 23 of different specifications, the fixing ring 19 is rotated, and the internal thread of the fixing ring 19 cooperates with the external thread of the threaded column 18, and the fixing ring is away from the mounting plate, and the rotating rod 17 can drive the threaded column 18 to rotate out of the rotating groove 15, thereby achieving the separation of the mounting block 20 and the fixing seat 14, that is, completing the disassembly of the support beam 23. Similarly, during installation, it is only necessary to place the bottom of the mounting plate close to the fixing seat 14 and rotate the rotating rod 17 and the fixing ring 19. The rotating rod 17 will rotate outside the limiting rod 16 into the rotating groove 15, and the fixing ring 19 moves in the opposite direction and close to one side of the mounting block 20 to complete the installation of the support beam 23. The support beam 23 can be loaded and unloaded through the fixing seat 14, the limiting rod 16, the rotating rod 17, the threaded column 18, the fixing ring 19 and other components, so that it can be flexibly replaced according to usage requirements, and the difficulty of replacement can also be reduced.
