Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, and more particularly to a cable protection device for electric power engineering. Background Art

[0002] Power engineering refers to a series of projects involving power generation, transmission, transformation, distribution and consumption. During the cable laying process, it is usually necessary to install cable supports on the walls near the substation and on the poles used to deliver electricity to residents' homes to support and protect the cables. In the use of existing power engineering cable protection devices, the two protection plates for the cables are usually connected by multiple screws before the cables can be installed. During installation, workers need to use professional tools to screw multiple screws to complete the operation. The operation is relatively complicated, which reduces the efficiency of cable installation and is very inconvenient to use. Secondly, in the use of existing power engineering cable protection devices, since the edges on both sides of the support plates for installing the cables are relatively sharp, the cables often vibrate under the action of wind during use, causing friction between the cables and the two sides of the support plates. After a long time, the outer layer of the cable is easily scratched, thereby reducing the service life of the cable. Utility Model Content

[0031] In this embodiment, when it is necessary to install the cable, the cable to be installed is passed through the openings 10 on the first clamping plate 3 and the second clamping plate 8 to the bottom of the first clamping plate 3 and the second clamping plate 8 in turn, and the handle 6 is turned. The handle 6 drives the first screw 5 to rotate. Since the first screw 5 is threadedly connected to the drive seat 7, the drive seat 7 moves along the drive chamber 4, and the drive seat 7 drives the two second clamping plates 8 to move, so that the second clamping plate 8 moves along the limit groove 9. With the cooperation of the first clamping plate 3 and the second clamping plate 8, the cable is restricted to the position between the support plate 2 and the first clamping plate 3 and the second clamping plate 8, and the clamping of the cable can be completed. The first clamping plate 3 and the second clamping plate 8 protect the installed cable.

[0032] More specifically, the cable is sequentially moved from the openings 10 of the first and second clamping plates 3 and 8 to the lower ends of the first and second clamping plates 3 and 8. The second clamping plate 8 is moved by rotating the handle 6, thereby completing the installation of the cable. The first and second clamping plates 3 and 8 protect the cable. The two guide wheels 11 can rotate and support the cables on both sides of the support plate 2, thereby protecting the cables.

[0033] See also Figure 1-5, as an implementation method for installing the wire wheel 11: an insertion rod 12 is respectively provided on both sides of the wire wheel 11, and the outer sides of the two insertion rods 12 are movably connected to a first bearing 13, and the wire assembly also includes a mounting shell 14 fixedly arranged on one side of the support plate 2, and a second screw 15 is rotatably provided in the mounting shell 14, and one end of the second screw 15 passes through the mounting shell 14 and is fixedly connected to a handle 16, a movable seat 17 is threadedly connected to the second screw 15, and one end of the movable seat 17 passes through the mounting shell 14 and is fixedly connected to a movable plate 18, and mounting holes 19 are respectively provided on the movable plate 18 and the support plate 2, and the two first bearings 13 are respectively mounted in the two mounting holes 19.

[0034] Specifically, the wire wheel 11 drives the two insertion rods 12 to move, and one end of the insertion rod 12 is inserted into the first bearing 13 installed on the support plate 2. The handle 16 is turned, and the handle 16 drives the second screw 15 to rotate. The second screw 15 drives the moving seat 17 to move, and the moving seat 17 drives the moving plate 18 to move. The moving plate 18 drives the first bearing 13 thereon to move, so that the other insertion rod 12 of the wire wheel 11 is inserted into the first bearing 13 on the moving plate 18, and the installation of the wire wheel 11 can be completed.

[0035] See also Figure 1-5 , as an implementation method for fixing the cable: the first clamping plate 3 and the second clamping plate 8 are respectively threaded with bolts 20, and the first clamping plate 3 and the second clamping plate 8 are slidably connected with a fixing plate 21 through a track structure, each of the fixing plates 21 is provided with a second bearing 22, and the fixing plate 21 is rotatably connected to the bolt 20 through the second bearing 22, and two placement grooves 23 are provided on the support plate 2.

[0036] Specifically, when laying the cable, the cable is placed in the placement groove 23 of the support plate 2, and the bolt 20 is rotated. Since the bolt 20 is threadedly connected to the first clamping plate 3 or the second clamping plate 8, the bolt 20 rotates and moves downward. The lower end of the bolt 20 rotates through the second bearing 22. At the same time, the bolt 20 pushes the fixed plate 21 to move downward, so that the fixed plate 21 moves downward along the first clamping plate 3 or the second clamping plate 8. The fixed plate 21 cooperates with the support plate 2 to fix the cable in the placement groove 23, thereby fixing the cable.

[0037] In summary, when the overall equipment is in use:

[0038] When the cable needs to be installed and protected, the mounting plate 1 is provided with a plurality of fixing holes, which can be installed on the wall where the cable needs to be installed. The cables to be installed are passed through the openings 10 on the first clamping plate 3 and the second clamping plate 8 in turn to the bottom of the first clamping plate 3 and the second clamping plate 8, and the handle 6 is turned. The handle 6 drives the first screw 5 to rotate. Since the first screw 5 is threadedly connected to the drive seat 7, the drive seat 7 moves along the drive chamber 4, and the drive seat 7 drives the two second clamping plates 8 to move, so that the second clamping plate 8 moves along the limit groove 9. With the cooperation of the first clamping plate 3 and the second clamping plate 8, the cable is restricted to the position between the support plate 2 and the first clamping plate 3 and the second clamping plate 8, and the cable clamping can be completed. The first clamping plate 3 and the second clamping plate 8 protect the installed cable.

[0039] When the installed cable needs to be fixed, when installing the cable, the cable is placed in the placement groove 23 of the support plate 2, and the bolt 20 is rotated. Since the bolt 20 is threadedly connected to the first clamping plate 3 or the second clamping plate 8, the bolt 20 rotates and moves downward. The lower end of the bolt 20 rotates through the second bearing 22. At the same time, the bolt 20 pushes the fixing plate 21 to move downward, so that the fixing plate 21 moves downward along the first clamping plate 3 or the second clamping plate 8. The fixing plate 21 cooperates with the support plate 2 to fix the cable in the placement groove 23, thereby fixing the cable.

[0040] When it is necessary to protect the cables on both sides of the support plate 2, the wire pulley 11 drives the two rods 12 to move, and one end of the rod 12 is inserted into the first bearing 13 installed on the support plate 2. The handle 16 is turned, and the handle 16 drives the second screw 15 to rotate. The second screw 15 drives the moving seat 17 to move, and the moving seat 17 drives the moving plate 18 to move. The moving plate 18 drives the first bearing 13 thereon to move, so that the other rod 12 of the wire pulley 11 is inserted into the first bearing 13 on the moving plate 18, and the installation of the wire pulley 11 is completed. The two wire pulleys 11 can rotate and support the cables on both sides of the support plate 2, thereby protecting the cables.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
