Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electric power construction, in particular to a cable laying guide device for electric power construction. BACKGROUND

[0002] In the patent application with the application publication number CN219833571U, a cable guide unit and a telescopic component are included; the cable guide unit is arranged in a corner cable well for cable laying; the telescopic component is arranged between the cable guide unit and the inner wall of the corner cable well and connected with both. The advantages are: by adjusting the telescopic component to link the cable guide unit to a suitable position, the cable guide unit provides a guiding effect for the cable to be laid, thereby reducing the friction force of cable laying, ensuring the quality of cable laying and saving the pulling force of the traction machinery. In addition, the telescopic component and the cable guide unit have strong applicability when used in combination, and can be installed and used in different size corner cable wells and different pipe laying positions. Moreover, the structure is detachable, simple to manufacture and install, easy to operate, convenient to popularize, low in cost and easy to carry.

[0003] In the prior art including the above-mentioned patent, in the cable laying of electric power engineering, the cable well has narrow space, is easy to accumulate dust, mosquitoes and stones, and brings difficulties to cable laying. The existing guide and protection devices are difficult to consider the "narrow space adaptation, twist self-adaptation and debris protection" at the same time, and the specific problems are as follows:

[0004] I. Poor narrow space adaptability. The existing cable well guide devices are divided into two categories: one is a fixed angle steel support, which cannot be dynamically adjusted after being fixed, and rigid friction is easy to occur when the cable is twisted, causing the outer skin to be scratched; the other is a portable folding support, which needs to be repeatedly calibrated by workers up and down the well, which is low in efficiency and has safety risks. Both types of devices are rigid structures and cannot rotate synchronously with the cable twist, which is easy to form "stuck effect" and may cause the insulation layer of high-voltage cable to crack.

[0005] II. Split functions and high cost. The cable twist rate in the cable well is 15%-20%, but the existing twist detection requires additional equipment: manual observation has low accuracy, the distributed fiber system costs more than 20,000 yuan and is easily affected by moisture. At the same time, the rolling components (such as balls) of the guide device are easy to accumulate debris, which increases the traction resistance by 30%-50% and scratches the cable outer skin, causing the insulation performance to decrease.

[0006] III. Insufficient adaptability of cleaning solutions. The existing cleaning technology is difficult to adapt to the cable well environment: liquid flushing type is easy to accumulate water and rust the components, causing short circuit; electric brush type relies on power supply, has high failure rate in humid and dusty environment and high maintenance cost. SUMMARY

[0007] The present application aims to solve the problems of the current device, which has three major pain points of narrow space adaptation difficulty, function fragmentation, and cleaning solution inadaptation, and needs to integrate a low-cost and high-reliability device with dynamic guidance, torsional self-adaptation, and mechanical cleaning.

The fixed plate two is fixed only on one of the installation blocks. The remaining installation blocks are not provided with the fixed plate two. The spring two is used to assist the installation block to reset after torsion.

[0014] As preferred, four telescopic supports are arranged on each mounting block, and two telescopic supports are arranged in each group, one end of the telescopic support close to the inner side of the mounting block is fixedly connected with the mounting block, and the one end of the telescopic support in the mounting block is sleeved with a spring.

[0015] As preferred, an inner concave surface is arranged on each side of the rotating rod, the inner concave surface of the rotating rod is provided with an abrasive surface, and the surface of the telescopic support in contact with the rotating rod is also provided with an abrasive surface.

[0016] As preferred, a scale bar is fixedly arranged on one side of the mounting block at the upper end of the mounting ring, the scale bar is rotationally connected with the mounting ring, a pointer is fixedly arranged on the outer side of the scale bar at the upper end of the mounting ring, and the tip of the pointer is in contact with the side surface of the scale bar.

[0041] The working principle and use process of the present application are as follows:

[0042] When the device is installed:

[0043] First, the hanging plate 603 is clamped below the limiting ring 2, and the cable 602 is passed through the installation ring 1, then the rope is passed through the lifting lug 601, so that the rope can be used to lift the whole device and send it into the cable well; when the device moves to the appropriate position, loosen the rope, pull out the rope from the lifting lug 601 and at the same time pull the cable 602 tight, at this time the installation ring 1 freely falls under the action of gravity, and the limiting ring 2 will not move under the action of the cable 602, so that the supporting frame 3 can be opened by cooperating with the installation ring 1, and can be supported on the inner wall of the cable well to complete the installation; finally, when taking out the hanging plate 603, it only needs to be sent down by a distance, and after deflection, it can be pulled out;

[0044] It is worth noting that the rope passing through the lifting lug 601 is temporary fixed, and needs to be removed in time when the device is moved into position;

[0045] When guiding the cable:

[0046] Before the cable enters, a plurality of clamps 401 are first installed equidistantly on the surface of the cable, and then the cable can be sent in; in the process of sending in the cable, the colored rope 403 is put into the clamp 401, and the limiting clamp 402 is fixed; it should be noted that when installing the clamp 401, it is necessary to ensure that each limiting clamp 402 is on the same straight line;

[0047] When the cable enters the device, the rotating roller 504 and the telescopic support 502 cooperate with each other to restrict the cable at the center position of the device, and the rotating roller 504 can roll with the passing of the cable; as the cable continues to be laid, when the clamp 401 passes through the rotating roller 504, the rotating roller 504 and the telescopic support 502 will be forced to move outward to avoid the clamp 401, and when the clamp 401 leaves, the rotating roller 504 can be popped out to the middle under the action of its own elasticity and the spring 503 in the telescopic support 502, and the cable is clamped again, it is worth mentioning that at this time the rotating roller 504 can shake off the sundries adhered to its surface by using the vibration generated at this time;

[0048] It is worth noting that if the cable twists during laying, the twisted cable can rotate the mounting block 501 near it, and the worker can know where the cable twists and the twisting amplitude by observing the scale bar 505 interface. If the light is not good or the on-site conditions are not convenient for observation, the worker can know where the cable twists by observing the direction of the colored rope 403. After the cable laying is completed and the equipment is recovered, the paint wear on the side of the scale bar 505 can be observed to determine whether the cable has twisted and the maximum twisting angle.
