Technical Field

[0001] The present invention relates to the technical field of cable installation equipment, and particularly relates to a cable hanger. Background Art

[0002] Cables are usually fixed to brackets, walls or equipment by means of arc-shaped clamping seats, bolts or straps to prevent the cables from sagging due to their own weight, vibration, external pulling or vibration-induced deformation and wear. However, rail transit equipment travels in underground tunnels and underground roadways, where piston wind is likely to be generated. The cable is affected by the piston wind and pulls the arc-shaped clamping seat on the hanger, which easily loosens the bolts between the two arc-shaped clamping seats, resulting in the separation of the two arc-shaped clamping seats and the inability to fix the cable.

[0003] Therefore, there is an urgent need for a cable hanger that is convenient to install and has strong anti-pulling force to solve the problems raised in the above background art. Summary of the Invention

[0016] Combined with Figures 1-8 As shown, in this embodiment, a cable hanger includes an upper fixing seat 1 and a lower fixing seat 2. Arc-shaped grooves for clamping the cable are provided at one end of the upper fixing seat 1 and the lower fixing seat 2 that are close to each other. The upper fixing seat 1 and the lower fixing seat 2 clamp the upper and lower ends of the cable through the arc-shaped grooves, defining the position of the cable and preventing the cable from sagging due to its own weight. At the same time, by adjusting the positions of the upper fixing seat 1 and the lower fixing seat 2, the size of the clamping groove between the upper fixing seat 1 and the lower fixing seat 2 can be changed to meet the suspension of cables of different specifications.

[0017] In this embodiment, the limiting component includes a connecting sleeve 3, a main screw 4 and a locking screw 5. Among them, the connecting sleeve 3 is arranged between the upper fixed seat 1 and the lower fixed seat 2. An annular baffle 31 is arranged on the outer wall of the connecting sleeve 3. Threaded teeth 32 are arranged on the part of the outer wall of the connecting sleeve 3 below the annular baffle 31. A lower threaded hole 21 is opened inside the lower fixed seat 2. The connecting sleeve 3 is threadedly installed inside the lower threaded hole 21 through the threaded teeth 32. The connecting sleeve 3 is installed into the lower threaded hole 21 by the threaded teeth 32, and the main screw 4 is installed inside the lower fixed seat 2 through the connecting sleeve 3, realizing the connection between the upper fixed seat 1 and the lower fixed seat 2. At the same time, the connecting sleeve 3 supports the upper fixed seat 1 through the annular baffle 31, facilitating the adjustment of the height of the upper fixed seat 1.

[0018] In this embodiment, one end of the connecting sleeve 3 above the annular baffle 31 is inserted into the upper fixed seat 1. An annular groove 12 is opened around the outside of the upper threaded hole 11 on the lower end face of the upper fixed seat 1. The annular baffle 31 is clamped inside the annular groove 12, and an annular slot 13 is opened around the outside of the upper threaded hole 11 on the inner wall of the annular groove 12. One end of the connecting sleeve 3 above the annular baffle 31 is inserted into the annular slot 13. The upper fixed seat 1 is clamped on the top of the connecting sleeve 3 through the annular slot 13 and the annular groove 12, and then the main screw 4 is used to fix the connecting sleeve 3 at the bottom of the upper fixed seat 1, connecting the upper fixed seat 1, the connecting sleeve 3 and the lower fixed seat 2 at the other end of the connecting sleeve 3 to form a whole, realizing the connection and limitation between the upper fixed seat 1 and the lower fixed seat 2.

[0019] In this embodiment, the main screw 4 is arranged above the upper fixed seat 1. The main screw 4 sequentially passes through the upper fixed seat 1 and the connecting sleeve 3 and extends into the lower fixed seat 2. Upper threaded holes 11 and threaded grooves 33 are respectively opened inside the upper fixed seat 1 and the connecting sleeve 3. The main screw 4 is threadedly installed inside the upper threaded hole 11 and the threaded groove 33 and extends out of the connecting sleeve 3. The inner diameters and pitches of the upper threaded hole 11 and the threaded groove 33 are the same. The main screw 4 is installed inside the upper threaded hole 11 and the threaded groove 33 to lock the upper fixed seat 1, the connecting sleeve 3 and the lower fixed seat 2, preventing the upper fixed seat 1 from detaching from the lower fixed seat 2.

[0020] In this embodiment, the locking screw 5 is arranged below the lower fixing seat 2. The top end of the locking screw 5 is threadedly installed inside the lower fixing seat 2 and abuts against the connecting sleeve 3. A connecting screw 51 is provided at the top end of the locking screw 5. A threaded cavity 41 is formed at the bottom end of the main screw 4. The connecting screw 51 is threadedly installed inside the threaded cavity 41. The top end of the locking screw 5 abuts against the bottom end of the main screw 4. By installing the connecting screw 51 inside the threaded cavity 41, the main screw 4 and the locking screw 5 are integrated to achieve secondary locking between the upper fixing seat 1 and the lower fixing seat 2. At the same time, the connecting sleeve 3 abuts against the locking screw 5, and the connecting sleeve 3 provides resistance to the axial tensile force of the main screw 4 and the locking screw 5, increasing the tensile strength of the upper fixing seat 1 and the lower fixing seat 2, preventing the cable from pulling the fixing seat off under the influence of piston wind, and improving the stability of cable installation.

[0021] In this embodiment, the length of the connecting sleeve 3 at the lower end below the annular baffle 31 is the same as the depth of the lower threaded hole 21. By adjusting the depth of the connecting sleeve 3 installed into the lower threaded hole 21, the distance between the upper fixing seat 1 and the lower fixing seat 2 can be adjusted.

[0022] In this embodiment, a locking nut 52 is provided on the outer wall of the locking screw 5. The locking nut 52 is threadedly installed on the outer wall of the locking screw 5 and tightened on the lower end face of the bracket. By tightening the locking nut 52 on the outer wall of the locking screw 5 on the lower end face of the bracket, the position of the locking screw 5 is limited, and the assembly of the upper fixing seat 1, the lower fixing seat 2 and the bracket is realized.

[0023] The working principle of the present invention is as follows: For the cable hanger proposed in this application, the main screw 4 and the connecting sleeve 3 are used to connect the upper fixing seat 1 and the lower fixing seat 2. By adjusting the depth of the connecting sleeve 3 installed into the lower threaded hole 21, the distance between the upper fixing seat 1 and the lower fixing seat 2 is changed, so that the upper fixing seat 1 and the lower fixing seat 2 clamp the outside of the cable through the arc-shaped grooves, preventing the cable from sagging due to its own weight and meeting the suspension of different specifications of cables. At the same time, the locking screw 5 passes through the through hole at the bottom of the bracket and is installed into the lower threaded hole 21, and the connecting screw 51 is tightened inside the main screw 4, so that the locking screw 5 tightens the connecting sleeve 3, connecting the main screw 4 and the locking screw 5 into a whole. Then, the locking nut 52 on the outer wall of the locking screw 5 is tightened on the lower end face of the bracket to complete the assembly of the upper fixing seat 1, the lower fixing seat 2 and the bracket, realizing the suspension of the cable. A composite tensile system can be formed by the axial tensile force of the main screw 4 and the locking screw 5 and multiple threaded friction resistances, increasing the tensile strength of the upper fixing seat 1 and the lower fixing seat 2, preventing the cable from pulling the fixing seat off under the influence of piston wind, and improving the stability of cable installation.
