Description

Technical Field

[0001] The present invention belongs to the technical field of cable support, and in particular relates to a cable support device for disaster relief emergency of a transmission tower. Background Art

[0002] Emergency cable support devices are often used to provide temporary support for existing cable support components on utility poles damaged by natural disasters. Their main features are easy installation and quick assembly and disassembly. Existing temporary cable support devices are generally fixed to the utility pole using clamps, and a temporary cable mount is installed on the support cantilever. During the assembly and disassembly process, workers usually need to carry the entire device up the utility pole, install the support device on the utility pole, and then connect the cables. The bolt connection process using clamps is also relatively cumbersome. Currently, there is also a type of cable support device that uses a buckle connection. Although it facilitates installation, its support strength is relatively low. Moreover, when disassembling it after the task is completed, workers need to carry it down the utility pole with them. In addition to the tools, they also need to hold the support device with both hands, which poses certain safety risks. Simply dropping it will cause the support device to deform and damage, which is relatively inconvenient.

[0003] Therefore, the present application proposes a cable support device for disaster reduction emergency of transmission towers to overcome the above-mentioned defects. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a cable support device for disaster reduction emergency of transmission towers.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a cable support device for disaster reduction and emergency use on a transmission tower, wherein the cable support device comprises a mounting seat which is attached to the circumference of the utility pole; A cantilever arm is fixedly mounted horizontally on a mounting base; A cable mounting assembly is installed on the cantilever along the extension direction of the cantilever; The embracing assembly is mounted on the electric pole in an embracing manner in conjunction with the mounting base; The clasping assembly includes two fixing members arranged on a mounting seat, and a mounting belt and a clamp are used between the two fixing members to form a clamp that is wrapped around the electric pole. At least three sliders are installed at equal angles on the clamp and the mounting seat. The roller of the slider 2 arranged on the clamp contacts the electric pole, and the slider 2 arranged on the mounting seat contacts the electric pole in an adjustably manner.

[0006] Preferably, the mounting seat comprises a first square steel and a second square steel respectively mounted on the upper and lower ends thereof, the first square steel and the second square steel are both provided with a locking knob, and the end of the locking knob is connected to the second slider; The second sliding block located on the mounting seat contacts the electric pole via a through slot provided on the mounting seat.

[0007] Preferably, the cantilever includes positioning grooves, and every two positioning grooves form a group. The cantilever is provided with a plurality of groups of positioning grooves along its extension direction. The cantilever is mounted on the channel steel of the square steel 1 through the positioning grooves and bolts. The cantilever is further provided with a strip-shaped through slot, and the strip-shaped through slot is provided in a plurality of groups along the extending direction of the cantilever.

[0008] Preferably, the cable mounting assembly includes a slide rail arranged inside the linear groove of the cantilever, and a plurality of sliders are slidably installed on the slide rail. The sliders are fixed to the cantilever by bolts passing through the strip groove, and a mount for supporting the cable is fixedly installed on the front of the slider.

[0009] Preferably, the cable mounting assembly also includes a gas rod connected between two adjacent sliders, and a conduit is connected between the two adjacent gas rods. The interior of the gas rod is divided into two parts by the piston of the piston rod, and the conduit connects two different cavity parts in the two adjacent gas rods to keep the telescopic condition of each gas rod consistent.

[0010] Preferably, the two parts of the installation belt and the clamp are fastened by buckles to form an embracing structure, and the installation belt always tightly embraces the pole body after the buckles are fastened.

[0011] Preferably, the fixing member is installed in the middle of the mounting seat; The mounting base extends downward by a length of not less than 15 cm based on the height of the fixing member.

[0012] Preferably, the square steel is further hinged with a support arm, the telescopic end of the support arm is hinged with one end of the cantilever, and the support arm is self-locking through the knobs on the telescopic sleeves at various levels. Compared with the prior art, the present invention has the following beneficial effects: The present invention unfastens the mounting strap and tightens the locking knob inward. The locking knob pushes the second slider on the mounting base into rolling contact with the pole. This creates a three-point rolling structure supported circumferentially around the pole, allowing the device to automatically slide downward along the pole. Compared to simply dropping the device, the speed of the rolling device is more controllable, resulting in a slow, low-impact landing and no deformation damage. This also frees the operator's hands, allowing them to hold onto the pole while climbing downward, reducing safety risks.

[0013] The present invention employs gas rods positioned between two adjacent sliders (one) and interconnected gas rods. This allows workers to adjust the poles on-site by simply horizontally shifting one slider (one) to simultaneously move the remaining sliders (one). Furthermore, the extension and contraction lengths of each gas rod are consistent, allowing multiple sliders (one) to simultaneously adjust the spacing between two adjacent sliders, ensuring consistent and synchronized spacing between multiple adjacent sliders (one). This eliminates the need for measurement and calibration, avoiding the potential for errors and inconvenience associated with visual adjustments. Operation is also relatively quick and easy.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figures 1 to 9 As shown, the present invention provides a cable support device for disaster reduction emergency of a transmission tower, the cable support device includes a mounting base 100, which is attached to the circumference of the utility pole; The cantilever 200 is horizontally fixedly mounted on the mounting base 100; The cable mounting assembly 300 is installed on the cantilever 200 along the extension direction of the cantilever 200; The embracing assembly 400 cooperates with the mounting base 100 to be mounted on the utility pole in an embracing manner; The clamping assembly 400 includes two fixing parts 401 arranged on the mounting base 100. The two fixing parts 401 are connected by a mounting belt 402 and a clamp 403 to form a clamp that surrounds the utility pole. At least three sliders 500 are installed at equal angles on the clamp 403 and the mounting base 100; the clamp 403 is made of elastic plastic or metal and has elastic bending properties.

[0018] The roller of the second slider 500 disposed on the clamp 403 contacts the electric pole, and the second slider 500 disposed on the mounting base 100 contacts the electric pole in an adjustable manner.

[0019] The cable is supported by the cable mounting assembly 300 provided on the cantilever 200, and when the device is installed on the utility pole, it is installed by means of the mounting strap 402 and the clamp 403, both of which can play a fixing role when the slider 2 500 on the mounting seat 100 is not in rolling contact with the utility pole. The fixing effect is more stable than that of the existing single strap. When the device needs to be removed, the slider 2 500 on the mounting seat 100 is adjusted to contact and connect with the utility pole, and the mounting strap 402 is untied. The slider 2 500 then forms a roller structure that automatically slides down along the utility pole. There is no need for workers to carry down the utility pole, freeing up their hands.

[0020] like Figure 1 、 Figure 7-Figure 9 As shown, the mounting base 100 includes a square steel 101 and a square steel 102 mounted on the upper and lower ends thereof, respectively. The square steel 101 and the square steel 102 are both provided with a locking knob 103, and the end of the locking knob 103 is connected to the slider 2 500; The second sliding block 500 on the mounting base 100 contacts the electric pole via the through slot provided on the mounting base 100 .

[0021] When the slider 2 500 is not subjected to radial inward pressure from the locking knob 103, it is simply confined within the through-slot of the mounting base 100. The inner side of the mounting base 100 is in direct contact with the utility pole. At this point, the mounting base 100 forms a clamp that is fixed to the pole body by cooperating with the clamping assembly 400. When the support device needs to be disassembled downward, the mounting strap 402 is unfastened and the locking knob 103 is tightened inward. The locking knob 103 pushes the slider 2 500 on the mounting base 100 into rolling contact with the pole. The slider 2 500 on the mounting base 100 and the slider 2 500 on the clamp 403 then form a three-point support rolling structure around the pole, allowing it to automatically slide downward along the pole. The speed of the rolling device is more controllable than simply dropping it, with a slow speed and minimal impact, preventing deformation and damage. Once the device has slid to the bottom of the pole, the clamp 403 is unfastened for easy disassembly.

[0022] like Figure 1 and Figure 2 As shown, the cantilever 200 includes positioning grooves 201, and each two positioning grooves 201 form a group. The cantilever 200 is provided with a plurality of groups of positioning grooves 201 along its extension direction. The cantilever 200 is mounted on the channel steel of the square steel 101 through the positioning grooves 201 and bolts. The cantilever 200 is further provided with strip-shaped through slots 202 , and a plurality of strip-shaped through slots 202 are provided along the extending direction of the cantilever 200 .

[0023] The positioning grooves 201 are arranged in pairs, vertically aligned with the two connecting holes on the channel steel, and the positioning installation is completed by bolts. There are multiple groups of positioning grooves 201 on the cantilever 200. The multiple groups of positioning grooves 201 can be fixed to the channel steel after the cantilever 200 is adjusted to extend in any direction on both sides of the utility pole, so as to facilitate the adjustment of the alignment between the cable support devices of two adjacent utility poles. This avoids the problem of the cable being arranged not straight due to the relatively fixed design length of the cantilever 200 in a certain direction, which reduces the fault tolerance. The main function of the strip through groove 202 is to cooperate with the cable mounting device to fix its position. The distribution range of the strip through groove 202 is relatively wide, and it can be fixed at almost most positions on the cantilever 200.

[0024] like Figure 1-Figure 3 As shown, the cable mounting assembly 300 includes a slide rail 301 arranged inside the linear groove of the cantilever 200, and a plurality of sliders 302 are slidably installed on the slide rail 301. The sliders 302 are fixed to the cantilever 200 by passing through the strip groove 202 through bolts 305. A mounter 303 for supporting the cable is fixedly installed on the front of the slider 302.

[0025] The cable mounting assembly 300 is used to mount cables. Multiple sliders 302 are slidably mounted on rails 301, adjusting the position of the mount 303 along the extension of the boom 200. This allows for convenient adjustment of the mount's position, allowing alignment with the cable support. Adjustment requires only a simple adjustment of the sliders according to the cable's extension direction. The position is then secured by tightening the nuts on the bolts 305.

[0026] like Figure 3 and Figure 5 As shown, the cable mounting assembly 300 also includes a gas rod 304 connected between two adjacent sliders 302, and a conduit 3041 is connected between the two adjacent gas rods 304. The interior of the gas rod 304 is divided into two parts by the piston of the piston rod. The conduit 3041 connects the two different cavity parts in the two adjacent gas rods 304 to keep the telescopic state of each gas rod 304 consistent.

[0027] By installing gas rods 304 between two adjacent sliders 302 and interconnecting them, workers can adjust the poles on site by simply moving one slider 302 horizontally to synchronize the movement of the remaining sliders 302. Furthermore, the extension and contraction lengths of each gas rod 304 are consistent, allowing multiple sliders 302 to adjust the spacing between them simultaneously and ensuring consistent, synchronized spacing between adjacent sliders 302. This eliminates the need for measurement and calibration, and avoids the inconvenience and potential errors associated with visual adjustments.

[0028] In order to further facilitate the staff to identify and adjust the length, technicians in the relevant field can engrave scales on the cantilever 200, and the staff can obtain the full length information by comparing the distance between one group of adjacent sliders 302.

[0029] like Figure 7 and Figure 8 As shown, the two parts of the installation belt 402 and the clamp 403 are buckled together by the buckle 404 to form an embracing structure. After the buckle 404 is buckled, the installation belt 402 is always tightly wrapped around the pole body.

[0030] The mounting strap 402 and the clamp 403 are both fastened together using a buckle 404, making the fastening process quick, convenient, and secure. When the clamp 403 is fastened and the mounting strap 402 is unlocked, it can help absorb the eccentric force exerted on the cable when it is loaded, providing a strong encircling and securing effect.

[0031] like Figure 1 As shown, the fixing member 401 is installed in the middle of the mounting base 100; The mounting base 100 extends downward by a length of not less than 15 cm based on the height of the fixing member 401 .

[0032] The inner side surface of the mounting base 100 is arc-shaped, and it can fit on the pole body of the utility pole. The cantilever 200 is also loaded with cables and the like due to its own weight. Therefore, relying solely on the embracing assembly 400 for encircling and fixing is not stable and may cause the cantilever 200 to fall. By setting the mounting base 100 to extend downward in contact with the surface of the utility pole, the eccentric force at the position of the cantilever 200 can be offset, providing support and anti-slip effect. There are also requirements for the length of the mounting base 100, which is generally not less than 15 cm. The specific length can be determined by people in the field according to the specific conditions of the use environment.

[0033] like Figure 1 and Figure 3 As shown, a support arm 600 is movably hinged on the square steel 102, and the telescopic end of the support arm 600 is movably hinged to one end of the cantilever 200. The support arm 600 is self-locked by knobs provided on the telescopic sleeves at various levels thereon.

[0034] The support arm 600 is used to support the cantilever 200. Its length can be adjusted according to the extension length of the cantilever 200 on both sides of the utility pole, and each level of the sleeve is provided with a self-locking knob, which can fix the adjusted length, forming a stable triangular structure between the cantilever 200 and the mounting base 100, effectively improving its supporting strength and preventing the cantilever 200 from breaking due to excessive load in harsh environments such as rain, snow or strong winds.

[0035] The working principle and use process of the present invention: When installing the device on a utility pole, the locking knob 103 is not tightened first. The slider 2 500 on the mounting base 100 is merely positioned within the through slot of the mounting base 100. The inner side of the mounting base 100 is in direct contact with the utility pole. The mounting base 100 is then secured to the utility pole body by cooperating with the clamping assembly 400 to form a clamp. When the support device needs to be disassembled downward, the mounting strap 402 is unfastened and the locking knob 103 is tightened inward. The locking knob 103 is used to push the slider 2 500 on the mounting base 100 into rolling contact with the utility pole. The slider 2 500 on the mounting base 100 and the slider 2 500 on the clamp 403 then form a three-point support rolling structure around the circumference of the utility pole, enabling the slider 2 500 to automatically slide downward along the utility pole.
