[0002] The cables in the underground pipe gallery are generally installed on the cable rack. The cable rack generally includes a support arm fixedly installed on the side wall of the pipe gallery. The support arm is provided with multiple mounting holes. After the cables are placed on the support arm, they are fixed to the support arm with a U-shaped clamp.

[0003] However, when securing cables with existing cable racks, the U-shaped clamps need to be inserted through the mounting holes and then nuts installed on the ends of the U-shaped clamps, which is cumbersome and results in low installation efficiency. Furthermore, when inspecting the cables, the mounting nuts need to be loosened before the cables can be removed, which is inconvenient. Utility Model Content

[0004] The utility model aims to provide an underground pipe gallery cable rack to solve the technical problems in the prior art of using U-shaped clamps to fix cables, which requires screwing nuts and causes inconvenience in operation and low installation efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A cable rack for an underground pipe gallery includes a supporting arm with multiple groups of mounting holes provided along its length, each mounting hole group including a rectangular long hole and two circular holes respectively located on both sides of the rectangular long hole. The underground pipe gallery cable rack also includes a U-shaped piece, both ends of the U-shaped piece are rotatably provided with a clamping piece capable of passing through the rectangular long hole, both ends of the clamping piece are provided with a clamping protrusion for clamping into the corresponding circular hole, and the U-shaped piece is provided with an elastic piece for being compressed after fixing the cable so that the clamping protrusion and the circular hole maintain a clamping fit.

[0007] The utility model is further configured as follows: the elastic member is a spring, two springs are provided and are respectively arranged at both ends of the U-shaped member, both ends of the U-shaped member are provided with a gasket that abuts one end of the spring, the outer diameter of the gasket is greater than the width of the rectangular long hole and is used to abut against the support arm, and the end of the spring away from the gasket is provided with a limiting member for abutting against the spring and limiting the spring.

[0008] The utility model is further configured as follows: the limiting member is a U-shaped sleeve, and both ends of the U-shaped sleeve are respectively in contact with one end of the two springs.

[0009] The utility model is further configured as follows: the elastic member is an elastic sleeve, the elastic sleeve is arranged in the middle of the U-shaped member, and after the cable is fixed, the elastic sleeve is between the U-shaped member and the cable and is compressed.

[0010] The utility model is further configured as follows: the round holes and the rectangular long holes are alternately arranged along the length direction of the support arm, so that two adjacent mounting hole groups share one round hole.

[0011] The utility model is further configured as follows: the supporting arm is made of channel steel.

[0012] The utility model is further configured as follows: a mounting seat is provided at the root of the support arm, and a bolt hole for the bolt to pass through is opened on the mounting seat.

[0013] The utility model is further configured as follows: a triangular reinforcing rib is provided between the lower side of the root of the support arm and the mounting seat.

[0014] In summary, the beneficial technical effects of the present invention are:

[0015] After placing the cable on the support arm, turn the opening of the U-shaped part downward so that the cable is clamped inside the U-shaped part. Then, align the clamping part on the U-shaped part with the corresponding rectangular long hole and press the U-shaped part so that the clamping part passes through the rectangular long hole. During this process, the elastic part will be compressed and deformed. After the clamping part passes through the rectangular long hole, the operator rotates the clamping part 90° so that the clamping protrusion on the clamping part aligns with the corresponding circular hole. Finally, the U-shaped part is released. The elastic part generates a thrust on the U-shaped part under the action of returning to its original state, so that the clamping protrusion always remains clamped in the circular hole, preventing the clamping part from rotating, and further preventing the clamping part from falling out of the rectangular long hole, thereby ensuring the stability of the U-shaped part. Compared with the structure of tightening a nut to fix the U-shaped clamp in the prior art, the installation operation of this underground pipe corridor cable rack is simpler and the installation efficiency is higher.

[0021] The present invention will be described clearly and completely below with reference to the embodiments.

[0022] Example 1:

[0023] Referring to the accompanying drawings, an underground pipe gallery cable rack includes a support arm 1 and a U-shaped member for fixing cables.

[0024] The bracket arm 1 is made of channel steel with its opening facing downward. One end of the bracket arm 1 is the mounting end, and the other is the cantilever end. A camouflaged mounting base 2 is fixed to the mounting end of the bracket arm 1. The mounting base 2 has bolt holes 3 for bolts to pass through. A triangular reinforcing rib 4 is provided between the mounting end (i.e., the base) and the mounting base 2 to enhance the support capacity of the bracket arm 1.

[0025] The web of the support arm 1 is provided with multiple groups of mounting holes along its length. Each mounting hole group includes a rectangular elongated hole 5 and two circular holes 6 located on either side of the rectangular elongated hole 5. The length of the rectangular elongated hole 5 is perpendicular to the length of the support arm 1. The circular holes 6 and the rectangular elongated holes 5 are alternately arranged along the length of the support arm 1 so that two adjacent mounting hole groups share a circular hole 6.

[0026] Both ends of the U-shaped part 7 are rotatably provided with a clamping part 8 that can pass through the rectangular long hole 5. Both ends of the clamping part 8 are provided with a clamping protrusion 9 for clamping into the corresponding circular hole 6. In order to facilitate the clamping protrusion 9 to enter the circular hole 6, the top of the clamping protrusion 9 is rounded. The U-shaped part 7 is provided with an elastic part for keeping the clamping protrusion 9 and the circular hole 6 in a clamping fit after the cable is fixed.

[0027] In this embodiment, the elastic member is a rubber elastic sleeve 10 that is sleeved over the U-shaped member 7. The elastic sleeve 10 is located in the middle of the U-shaped member 7. After placing the cable on the support arm 1, the opening of the U-shaped member 7 is turned downward to lock the cable within the U-shaped member 7. The clamping member 8 on the U-shaped member 7 is then aligned with the corresponding rectangular slot 5 and the U-shaped member 7 is pressed to pass through the slot 5. During this process, the elastic sleeve 10 is compressed and deformed. After the clamping member 8 passes through the slot 5, the operator rotates the clamping member 8 90° so that the locking protrusion 9 on the clamping member 8 is aligned with the corresponding circular slot 6. Finally, the U-shaped member 7 is released. The elastic sleeve 10, in its original position, exerts a thrust on the U-shaped member 7, keeping the locking protrusion 9 locked in the circular slot 6, preventing the clamping member 8 from rotating and, in turn, from falling out of the slot 5, thus ensuring the stability of the U-shaped member 7.

[0028] Example 2:

[0029] This embodiment is based on the first embodiment, and differs from the first embodiment in that the elastic member in this embodiment is a spring 11. Two springs 11 are provided and are respectively mounted on both ends of the U-shaped member 7. Both ends of the U-shaped member 7 are provided with a gasket 12 that abuts one end of the spring 11. The outer diameter of the gasket 12 is greater than the width of the rectangular long hole 5 and is used to abut against the support arm 1. The end of the spring 11 away from the gasket 12 is provided with a limiter for abutting against the spring 11 and limiting the position of the spring 11. The limiter is a rigid U-shaped sleeve 13, and the two ends of the U-shaped sleeve 13 abut against one end of the two springs 11 respectively.

[0030] In this embodiment, the spring 11 is used as the elastic member, which can provide a greater elastic restoring force and further improve the stability of the U-shaped member 7.

[0031] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
