Description

Technical Field

[0001] The present invention relates to the technical field of cable brackets, and particularly to a cable trench cable bracket facilitating cable installation. Background Technique

[0002] A cable trench refers to a dedicated underground passage for laying cables. Before laying cables, a cable trench is first excavated, then cable brackets are laid in the cable trench, and then the cables are laid on the cable brackets for installation. Existing cable brackets are generally made of simple angle steel profiles formed by welding or die-casting, and are provided with rotatable cable laying support arms. During laying, the cables are unrolled and expanded manually, and then carried and placed on the support arms. However, there are still some problems with existing cable brackets, which are as follows:

[0003] The support arms of existing cable brackets for supporting cables are simply hinged to the bracket body. However, this method not only requires manual up-and-down handling of the cables during cable installation, making the cable installation very time-consuming and laborious, but also the existing cable brackets cannot effectively fix the cables after cable installation, resulting in easy displacement of the cables on the support arms. Moreover, if there is subsequent maintenance and repair of the cables, it will also form an obstruction between adjacent cables, affecting the subsequent installation after cable repair.

[0004] Therefore, we propose a cable trench cable bracket facilitating cable installation. Summary of the Invention

Detailed implementation manners

[0030] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of each structure described in the following embodiments are only examples. The cable trench cable bracket for facilitating cable installation involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1-3, A cable trench cable support facilitating cable installation, comprising a support body 1 and a straight plate 2. An end support assembly 3 is movably installed inside the support body 1, and a jacking assembly 4 is movably installed inside the end support assembly 3. A lining block 5 is embedded and installed inside the support body 1. Side strip assemblies 6 are respectively installed on both sides of the support body 1. An external drive motor 7 is fixedly installed on one side of the straight plate 2, and a clamping and moving assembly 8 is fixedly installed on the other side of the straight plate 2. A clamping head 9 is movably installed at the bottom end of the clamping and moving assembly 8;

[0032] In this embodiment, it should be noted that by providing a movable jacking assembly 4 on the end support assembly 3, the rotation of the drive screw 405 drives the entire jacking assembly 4 to move up and down. In this way, the support roller 404 can be jacked up during the cable installation process, and then it can be used to support and guide the cable during the installation process. The upper clamping head 9 will pull the cable to move continuously. Thus, during the cable installation process, as long as the cable is fixed on the clamping head 9, the cable can be pulled by it and placed on the end support assembly 3 to complete the installation. After the installation is completed, the air bag 406 will be compressed, and then the outer arc plate 409 will be pushed out of the end support assembly 3. At the same time, in combination with the inner arc plate 411 and the docking head 412, it can ensure that the cable is locked after being placed, thereby ensuring the stability of the cable after installation. At the same time, by providing a bottom groove 32 and a positioning groove 33 on the support arm 31, the jacking assembly 4 can support the cable upward when the cable needs to be installed, and the positioning groove 33 can limit the placement of the jacking assembly 4 after it is retracted after the cable is laid. In combination with the setting of the reinforcing rod 34, it can ensure the support effect on the cable while ensuring the overall strength of the support arm 31, thereby making the cable installation more convenient and reliable.

[0033] Please refer to Figures 1-4 , A cable trench cable support facilitating cable installation, comprising an end support assembly 3. The number of end support assemblies 3 is multiple and they are rotatably installed at uniform intervals inside the support body 1. The number of jacking assemblies 4 located inside the end support assembly 3 is also multiple and they are movably installed at uniform intervals. The lining block 5 is inserted and installed inside the support body 1 and is located above the corresponding end support assembly 3;

[0034] In this embodiment, it should be noted that the clamping and moving assembly 8 can be used to move in the side strip assembly 6 to pull the cable to move on the jacking assembly 4, thereby realizing the laying of the cable, ensuring that the cable will not damage the outer skin during the laying process, and also being more time-saving and labor-saving.

[0035] Please refer to Figures 1-4, A cable trench cable support facilitating cable installation, comprising a lining block 5. The two sides of the lining block 5 are respectively inserted into the inner parts of side strip assemblies 6 arranged on both sides of the support main body 1, and the upper and lower parts at both ends are inserted into the support main body 1 through bumps. The lining block 5 and the side strip assemblies 6 can be completely and flushly butted, that is, the structures opened on both are exactly the same;

[0036] In this embodiment, it should be noted that this can ensure that the clamping and moving assembly 8 can drive the clamping head 9 to move very smoothly during the moving process, and then drive the cable end held by the clamping head 9 to pull the subsequent cable for laying. This can greatly reduce the difficulty of cable laying and improve the laying effect and convenience.

[0037] Please refer to Figures 1-2 , A cable trench cable support facilitating cable installation, comprising a clamping and moving assembly 8. One end of the clamping and moving assembly 8 is movably inserted into the side strip assembly 6. The clamping head 9 is composed of two semi-circular ring blocks, and the bottom ends of the ring blocks are locked and connected by bolts. Rubber gaskets are attached to the inner surfaces of the two semi-circular ring blocks of the clamping head 9;

[0038] In this embodiment, it should be noted that by placing the cable end between the two semi-circular ring blocks of the clamping head 9 and then locking the cable end with bolts, one end of the clamping and moving assembly 8 can be driven by the external drive motor 7, so that the straight plate 2 and the other end of the clamping and moving assembly 8 can both move horizontally under the limiting action of the side strip assembly 6 and the lining block 5, realizing the automatic traction operation of cable laying and greatly increasing the convenience of cable installation operation.

[0039] Please refer to Figures 3-5 , A cable trench cable support facilitating cable installation, comprising a supporting assembly 3. The supporting assembly 3 includes a supporting arm 31. Bottom grooves 32 are evenly spaced inside the supporting arm 31. Positioning grooves 33 are opened on both sides above the bottom grooves 32. A reinforcing rod 34 is movably inserted into the supporting arm 31. Inner grooves 35 are opened in the supporting arm 31 on both sides of the positioning grooves 33;

[0040] In this embodiment, it should be noted that one end of the supporting arm 31 is movably installed inside the bracket main body 1 through a pin shaft. The positioning groove 33 is semicircularly opened and communicates with the bottom groove 32 at the bottom end. The reinforcing rods 34 are symmetrically inserted and installed on both sides of the supporting arm 31 in the transverse direction. A jacking assembly 4 is arranged through the inner groove 35. In this way, it can be ensured that the cable is supported by the jacking assembly 4 during the cable laying process, and the supporting effect of the jacking assembly 4 is removed after the laying is completed. Furthermore, the cable is positioned and restricted by the positioning groove 33, thereby avoiding the cables from winding and contacting each other after being laid on the traditional cable bracket, improving the heat dissipation during the use of the cable, and also avoiding affecting other cables when a certain cable is repaired during subsequent maintenance and repair.

[0041] Please refer to Figures 1-6 , a cable trench cable bracket convenient for cable installation, including a jacking assembly 4. The jacking assembly 4 includes a bottom plate 401. Two sides of the top end of the bottom plate 401 are respectively fixedly installed with vertical plates 402. The top ends of the vertical plates 402 are fixedly installed with cross plates 403. A support roller 404 is movably installed between the two cross plates 403. A driving screw 405 is movably installed at the bottom end of the bottom plate 401. An air collecting bag 406 is fixedly installed at the bottom end of the bottom plate 401. An air guide pipe 407 is connected through the air collecting bag 406. The top end of the air guide pipe 407 is fixedly installed with a jacking inner block 408. An outer arc plate 409 is movably installed at the end of the jacking inner block 408. A pleated cloth 410 is movably installed inside the outer arc plate 409. An inner arc plate 411 is movably installed inside the outer arc plate 409. A docking head 412 is fixedly installed at the top end of the inner arc plate 411;

[0042] In this embodiment, it should be noted that the cross-sectional shape of the toroidal surface of the support roller 404 is a concave structure, and this concave structure is upwardly protruding and supported within the bottom groove 32, that is, this docking position is the position where the support roller 404 rises to the maximum. The driving screw 405 is movably arranged through the bottom end of the supporting arm 31. The bottom end of the air collecting bag 406 is fixedly connected to the bottom end of the bottom groove 32. A compressed corrugated hose is arranged inside the jacking inner block 408, and one end of the hose is fixedly connected to the bottom end of the outer arc-shaped plate 409. The outer arc-shaped plate 409 is movably arranged inside the inner groove 35. The pleated cloth 410 and the inner arc-shaped plate 411 can extend and be movably arranged inside the outer arc-shaped plate 409. The docking head 412 is a magnetic block, and the two docking heads 412 on both sides can be magnetically docked. The bottom end of the inner arc-shaped plate 411 is fixedly connected to the top end of the pleated cloth 410. In this way, during the process of cable laying, the support roller 404 can be rotated to move upward to the bottom of the positioning groove 33 to support the cable. Under the clamping action of the clamping head 9 and the driving force of the outer driving motor 7 driving the clamping and moving assembly 8 to move, the cable is driven to unwind and lay. During the process, the rotation of the support roller 404 can enable the cable to be smoothly laid. And after the laying is completed, the support roller 404 can be moved downward by reversely rotating the driving screw 405, so that the laid cable falls into the positioning groove 33 for supporting placement. And during the downward movement, the compressed air collecting bag 406 will cause the gas therein to inflate the corrugated hose in the jacking inner block 408 through the air guide pipe 407, thereby ejecting the outer arc-shaped plate 409 from the inner groove 35. Then, in combination with manually pulling out the inner arc-shaped plate 411 from the outer arc-shaped plate 409, the docking heads 412 on both sides are magnetically docked to complete the position locking of the placed cable.

[0043] Please refer to Figures 2-7 , a cable trench cable support for facilitating cable installation, including a side strip assembly 6. The side strip assembly 6 includes a strip block 61. A central groove 62 is opened in the middle of one side of the strip block 61. Limiting grooves 63 are respectively opened at the upper and lower ends of both ends of the central groove 62. Straight grooves 64 are respectively opened at the upper and lower ends of the side of the strip block 61 where the central groove 62 is opened. A rack 65 is fixedly arranged at the bottom end inside the central groove 62. Clamping rings 66 are respectively fixedly installed on the outer sides of both ends of the strip block 61;

[0044] In this embodiment, it should be noted that one end of the strip block 61 is inserted into the side surface of the support main body 1. The cross-sectional shape of the central groove 62 is in a T shape. A lining block 5 is embedded and movably connected in the limiting groove 63. The straight groove 64 and the rack 65 are movably docked with one end of the clamping and moving assembly 8. In this way, the limitation of the central groove 62 and the straight groove 64 can ensure that the clamping and moving assembly 8 moves stably horizontally under the driving action of the outer driving motor 7, so as to ensure that the cable can be smoothly laid and placed in the supporting assembly 3 under the traction of the clamping head 9, avoiding excessive manual participation in the laying and improving the convenience of cable installation.

[0045] Please refer to Figures 2-8 A cable trench cable support facilitating cable installation, comprising a clamping and moving assembly 8. The clamping and moving assembly 8 includes a base block 81. A positioning convex rod 82 is fixedly installed at one end of the base block 81. A connecting rod is movably installed inside the base block 81, and a gear 83 is fixedly installed at the end of the connecting rod.

[0046] In this embodiment, it should be noted that the positioning convex rod 82 is movably arranged in the straight groove 64, the gear 83 is rotatably arranged in the central groove 62. One end of the connecting rod in the base block 81 is fixedly connected to the output shaft of the external drive motor 7. A roller is arranged at the bottom end of the straight plate 2. In this way, the external drive motor 7 can be used to drive the gear 83 to rotate. Under the action of the rack 65, the gear 83 can drive the whole straight plate 2 to move horizontally, and then the cable can be stretched and unreeled. It only needs to fix one end of the cable on the clamping head 9 manually throughout the process, so as to ensure the cable can be laid conveniently and efficiently.

[0047] Working principle: Insert the side bar assembly 6 into both sides of the support main body 1, then insert the inner lining block 5 into the side bar assembly 6 and the support main body 1 to complete the installation of the inner lining block 5 and the side bar assembly 6. Rotate the driving screw rod 405, and the driving screw rod 405 will drive the supporting roller 404 to move upward. All the supporting rollers 404 are adjusted and completed during the installation process of the support main body 1 according to the above steps. Then place one end of the cable into the clamping head 9, tighten the bolt below to complete the clamping of one end of the cable. Then insert the clamping and moving assembly 8 into the side bar assembly 6, place the straight plate 2 into the cable trench, and then start the external drive motor 7. The external drive motor 7 drives the gear 83 to rotate. Under the action of the rack 65, the gear 83 can drive the straight plate 2 to move horizontally, so that the clamping and moving assembly 8 drives the clamping head 9 to move, and thus the cable will be pulled continuously towards one end. During the process of the cable being unreeled and unfolded, the bottom end of the cable will be supported on the supporting rollers 404.

[0048] When the cable unreeling and unfolding is completed, loosen the bolt at the bottom of the clamping head 9, and then adjust all the driving screw rods 405 to make the driving screw rods 405 reverse to drive the supporting rollers 404 to descend. In this way, the cable will fall onto the positioning groove 33. During the descending process, the airbag 406 will be compressed, so that the gas therein will enter the jacking inner block 408 through the air guide pipe 407, and then the outer arc-shaped plate 409 will be jacked out of the inner groove 35. In this way, when manually completing the cable laying detection process, the used docking heads 412 can be magnetically docked to complete the laying and fixing of the cable.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
