A type of underground cable crossing protection device

Abstract

This utility model discloses an underground cable crossing protection device, belonging to the field of underground cable laying technology. The utility model includes a cable sleeve and a support frame. The cable sleeve has a connecting hole on its side wall, which is detachably connected to the support frame via a connector. A cable passes through the cable sleeve. The support frame has a through hole, allowing adjustment of the cable sleeve height to maintain a safe distance between cables. This prevents cables from tangling at crossing points, reducing safety risks.

Description

Technical Field

[0001] This utility model belongs to the field of underground cable laying technology, and specifically relates to an underground cable crossing protection device. Background Technology

[0002] Underground cable laying is a core component of power and communication system construction in mines, tunnels, and underground engineering projects. Its technical complexity stems from the unique underground working environment and stringent safety requirements. In the confined space of a mine, cable laying must be carried out in accordance with geological conditions, tunnel structure, and safety regulations to ensure power supply reliability, communication stability, and personnel safety.

[0003] In existing technologies, cables are usually pulled manually by construction workers. Over long distances, mechanical devices such as explosion-proof winches and pulley blocks are also used for pulling. Currently, the safe spacing of cables can be basically guaranteed in straight tunnels. However, when the tunnel turns or the cable needs to cross the tunnel, it is easy for the cables to cross and become entangled, which can cause safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an underground cable crossing protection device, which aims to solve the problem of cables easily crossing and tangling in local areas of roadways in the aforementioned background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A downhole cable crossing protection device, characterized in that it includes a cable sleeve and a support frame, the side wall of the cable sleeve is provided with a connection hole, the connection hole is detachably connected to the support frame through a connector, a cable passes through the cable sleeve, and the support frame is provided with a through hole.

[0007] Furthermore, the support frame is an equilateral right-angle support frame with multiple through holes on one side to adjust the height of the cable sleeve.

[0008] Furthermore, there are several support frames, which are connected in sequence by bolts.

[0009] Furthermore, the connector is a bolt, which fastens the cable sleeve and the support frame.

[0010] Furthermore, the connecting hole is provided with an internal thread and is adapted to fit the bolt.

[0011] The beneficial effects of this utility model are: it can adjust the cable hanging height according to actual needs, avoid tangling in complex lines, and ensure the safe spacing of cables. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-4 As shown: A downhole cable crossing protection device includes a cable sleeve 2 and a support frame 3. The side wall of the cable sleeve 2 is provided with a connection hole 4. The connection hole 4 is detachably connected to the support frame 3 through a connector. A cable 1 passes through the cable sleeve 2. The support frame 3 is provided with a through hole 6.

[0019] Furthermore, the support frame 3 is an equilateral right-angle support frame with multiple through holes 6 on one side, which can adjust the height of the cable sleeve 2 and maintain a safe distance during cable laying.

[0020] Furthermore, the connecting element is bolt 5, which fastens cable sleeve 2 and support frame 3.

[0021] Furthermore, there are several support frames 3, which are connected in sequence by bolts 5.

[0022] Furthermore, the connecting hole 4 is provided with an internal thread and is compatible with the bolt.

[0023] During the underground cable laying process, the support frame 3 is selected at a suitable position and direction and fixed to the roadway wall with bolts 5. If the height of a single support frame 3 cannot meet the requirements, several support frames 3 can be connected end to end with bolts 5 to further adjust the direction and height of the cable sleeve 2. The cable sleeve 2 is fastened to the support frame 3 with bolts 5, and then the cable 1 is inserted into the cable sleeve 2. This ensures a safe distance during the cable laying process, solves the problem of cable entanglement when the roadway turns, reduces the safety risks during the cable laying process, and ensures a safe underground environment.
