[0001] The present invention relates to the technical field of cable protection, and in particular to a mechanical traction cable laying device and a use method thereof. Background Art

[0002] With the reform and opening up, my country's economy has grown rapidly, the scale of the domestic electric power industry and data communication industry has continued to expand, and the demand for cables has also grown rapidly. At the same time, with the application of electricity and the Internet in life, people are becoming more and more dependent on the two, so the laying of traction cables has become very popular. Most of the existing cable protection devices are for protection during cable installation or movement. Merely relying on naked eye observation can only play a preventive role. When the most common underground cables are transporting electricity, changes in external climate and construction conditions lead to excessive traction, which is one of the main factors for the breakage of the matching traction rope. Once the matching traction rope breaks, it will cause safety problems to the surrounding residents and bring inconvenience to the users of this section of the line in their lives or work. Therefore, the inventors found that it is very important to be able to scientifically detect the traction force during the cable traction laying process. Summary of the invention

[0003] In view of the deficiencies in the prior art, an object of the present invention is to provide a mechanical traction cable laying device and a method of using the same, which can effectively ensure that the traction force can be scientifically detected during the cable traction laying process.

[0004] In order to achieve the above object, the present invention is implemented through the following technical solutions: In the first aspect, an embodiment of the present invention provides a mechanical traction cable laying device, characterized in that it includes a motor, a reel, a base, a first bracket, and a second bracket. The upper surface of the base is connected to the lower surface of the reel bracket by bolts. A reel is arranged in the middle of the reel bracket, and the reel is fixedly connected to the output end of the motor. Two first brackets are welded to the sides of the base respectively, and the two first brackets are arranged in parallel, the first bracket and the base are arranged in a vertical relationship, a first roller and a second roller are arranged between the two first brackets, the end of the first rotating shaft is fixedly connected to the upper part of the second bracket, the lower end of the second bracket is placed on the upper surface of the open space on the outer periphery of the tunnel, and the upper part of the second bracket provides vertical upward support force for the first rotating shaft.

[0005] As a further implementation, the first roller includes a first rotating shaft, a seal, a bearing seat, a roller skin, and a bearing.

[0006] As a further implementation, the structure of the second rolling drag is consistent with that of the first rolling drag.

[0007] As a further implementation, the first rotating shaft is an integrally formed structure.

[0008] As a further implementation method, a lightweight through hole is set on the first bracket. The lightweight through hole is rectangular, and the long side of the lightweight through hole is parallel to the line connecting the first roller and the second roller. At the same time, the lightweight through hole is set on the side length of the first bracket away from the base.

[0009] As a further implementation, the upper surface of the first roller and the upper surface of the reel are arranged at the same height.

[0010] As a further implementation method, when looking down at the device, the distance between the first roller and the second roller is the same as the diameter of the wire rope of the present application, and one end of the wire rope is fixedly connected to the drum. At the same time, the other end of the wire rope passes through the upper surface of the first roller, and then passes through the gap between the first roller and the second roller. Finally, the wire rope bypasses the bottom of the second roller and extends into the underground tunnel.

[0011] As a further implementation method, the cross-section of the base is rectangular. The base serves as a load-bearing body, and its shape can be set according to actual requirements. A wooden board or wood can be placed between the lower surface of the base and the ground to adjust the height of the base. Similarly, the lower surface of the second bracket can also achieve the same height adjustment as the base.

[0012] In a second aspect, an embodiment of the present invention further provides a method for using a mechanical traction cable laying device, comprising the following steps: In the first step, one end of the wire rope is fixedly connected to the drum. At the same time, the other end of the wire rope passes through the upper surface of the first roller, then passes through the gap between the first roller and the second roller, and finally the wire rope goes around the bottom of the second roller and extends into the underground tunnel. The other end of the wire rope is connected to one end of the rotary connector, and the other end of the rotary connector is connected to the cable wire mesh, and finally the cable wire mesh is connected to the cable; The second step is to start the motor. Since one end of the wire rope is fixedly connected to the drum and the other end of the wire rope is finally connected to the cable, the motor makes the wire rope rotate around the drum, so that the wire rope finally pulls the cable to move in the underground tunnel or pit. The third step is to control the motor to pause and install a tension meter in the horizontal section near the drum support: fix it to the traction wire rope through a clamp, and connect the other end to the extension section of the traction wire rope to measure the reading. ; Step 4: According to the calculation formula ; Where e represents the base of natural logarithms; Represents the density of the wire rope; D represents the diameter of the wire rope when it is bent, which can be regarded as the diameter of the first rolling drag; represents the friction coefficient; Represents the central angle of the wire rope when it is bent. For the convenience of calculation, When considered vertical ; Step 5: If > , it means that the wire rope is currently overloaded and there is a danger of the wire rope breaking, so the operation needs to be stopped.

[0013] As a further implementation method, the following steps are also included: Step 6: If necessary and under actual on-site operating conditions, after the wire rope passes through the bottom of the second roller, the tension meter can be installed on the wire rope away from the second roller to measure the reading. , Step 7: According to the calculation formula ; Where e represents the base of natural logarithms; Represents the density of the wire rope; D represents the diameter of the wire rope when it is bent, which can be regarded as the diameter of the second rolling drag; represents the friction coefficient; Represents the central angle of the wire rope when it is bent. For the convenience of calculation, When considered vertical ; Step 8: If > , it means that the wire rope is currently overloaded and there is a danger of the wire rope breaking, so the operation needs to be stopped.

[0014] The beneficial effects of the present invention are as follows: The second roller has the same structure as the first roller. The upper surface of the first roller and the upper surface of the drum are set at the same height. When looking down at the device, the distance between the first roller and the second roller is the same as the diameter of the wire rope of the present application. One end of the wire rope is fixedly connected to the drum. At the same time, the other end of the wire rope passes through the upper surface of the first roller, and then passes through the gap between the first roller and the second roller. Finally, the wire rope bypasses the bottom of the second roller and extends into the underground tunnel. If adjustment is necessary, a wooden board can be placed between the lower surface of the base and the ground to adjust the height of the base. Similarly, the lower surface of the second bracket can also be adjusted to the same height as the base. After adjusting the height in this way, the wire rope can maintain a stable angle in both the horizontal and vertical directions, which is conducive to scientific measurement and collection of numerical values. Through the objective calculation of the above two different formulas, the traction force can be scientifically detected during the cable traction and laying process to find out whether there is a risk of breakage.
