Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a tunnel assembled danger removal rod. Background Technique

[0002] A tunnel is an engineering structure buried in the stratum and is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. The structure of a tunnel includes two parts: the main building and auxiliary equipment. The main building consists of the tunnel body and the portal, and the auxiliary equipment includes refuge bays, fire protection facilities, emergency communication, and drainage facilities. Long tunnels also have special ventilation and lighting equipment. According to the geological conditions where the tunnel is located: soil tunnels and rock tunnels, during the construction process of the tunnel, there may be a possibility of crushed stone collapse, which poses a certain safety hazard to construction workers.

[0003] Therefore, danger removal in tunnel construction is an essential and important link that cannot be ignored. All dangerous rocks that may pose risks should be removed to ensure the safety of construction workers. In addition to using large machinery to enter the site for danger removal, the common danger removal method mainly relies on personnel, and the danger removal is carried out carefully by observing and knocking.

[0004] Currently, the common tool in tunnel construction is a danger removal rod. However, the existing danger removal rods usually have a fixed structure, are not convenient for combined disassembly and use, have low convenience in use, and reduce work efficiency. Therefore, a tunnel assembled danger removal rod is proposed to solve the problems mentioned above. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tunnel assembled danger removal rod, including an installation rod, one end of the installation rod is slidably installed with a striking rod, the end of the installation rod away from the striking rod is provided with an extension rod, the end of the extension rod away from the installation rod is provided with a pointed cone head, both the installation rod and the pointed cone head are fixedly connected with threaded heads near the extension rod, and positioning components are arranged at both the upper and lower ends of the extension rod;

[0007] The positioning component includes a bidirectional screw. One end of the bidirectional screw is fixedly connected to a connecting shaft, and the end of the connecting shaft away from the bidirectional screw is fixedly connected to an adjusting knob. The outer side of the bidirectional screw is threadedly connected with two threaded sleeves. Fixedly connected to the outer sides of the two threaded sleeves are sliding sleeves. Fixedly connected to one side of each sliding sleeve away from the threaded sleeve is a mounting plate, and fixedly connected to the opposite sides of the two mounting plates are limiting blocks.

[0008] Further, the threaded head is threadedly connected to the inside of the extension rod. Threaded holes adapted to the threaded head are provided at both the upper and lower ends of the extension rod. The limiting block extends into the threaded hole and cooperates with the threaded head.

[0009] Further, blind holes are provided on both sides of the threaded head, and the inside of the blind holes is adapted to the limiting block.

[0010] Further, the two threaded sleeves on the bidirectional screw are respectively located on two sections of the bidirectional screw with opposite thread directions.

[0011] Further, the bidirectional screw is located inside the extension rod. One end of the bidirectional screw is connected to the inside of the extension rod through a bearing. The adjusting knob has a hexagonal shape and is located outside the extension rod.

[0012] Further, a guide shaft is fixedly connected to the inside of the extension rod, and the sliding sleeve is movably sleeved on the outer wall of the guide shaft.

[0013] Further, a spring is fixedly connected to the side of the mounting plate away from the limiting block, and the end of the spring away from the mounting plate is fixedly connected to the inside of the extension rod.

[0014] Compared with the prior art, the present utility model provides a tunnel assembled risk removal rod, which has the following beneficial effects:

[0015] For this tunnel assembled risk removal rod, the mounting rod and the pointed cone head are both assembled with the extension rod through the threaded head. The assembly is convenient. The setting of the positioning component on the extension rod realizes the fixation of the threaded head, avoiding the separation of the threaded head from the extension rod and improving the firmness of the installation. By rotating the adjusting knob to drive the bidirectional screw to rotate and drive the two threaded sleeves to move towards each other, the limiting block is driven to move through the mounting plate, so that the limiting block is separated from the threaded head, facilitating the disassembly of the threaded head. The combination is convenient to disassemble and use, which solves the problem that the existing risk removal rods usually have a fixed structure, are not convenient to be assembled and disassembled for use, have low convenience in use, and reduce the work efficiency.

Threaded heads 5 are fixedly connected to both the mounting rod 1 and the pointed cone head 4 near the extension rod 3, and the threaded heads 5 are threadedly connected to the inside of the extension rod 3

[0023] It should be noted that threaded holes adapted to the threaded heads 5 are provided at both the upper and lower ends of the extension rod 3

[0024] In this embodiment, positioning components are provided at both the upper and lower ends of the extension rod 3. The positioning components include a bidirectional screw 7. The bidirectional screw 7 is located inside the extension rod 3. One end of the bidirectional screw 7 is fixedly connected to a connecting shaft 8. The other end of the bidirectional screw 7 is connected to the inside of the extension rod 3 through a bearing. The end of the connecting shaft 8 away from the bidirectional screw 7 is fixedly connected to an adjusting knob 9. The outer shape of the adjusting knob 9 is hexagonal.
