Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a supporting device for cable channel installation which can prevent the cable channel from being dragged and cut. Background Art

[0002] Secondary control cables are special cables used to connect various measurement and protection devices in power systems. They play a vital role in the normal operation and safety protection of power systems. These cables are usually used to transmit control signals, measurement data and protection commands, ensuring that power equipment can be accurately monitored and controlled under various working conditions. Since they need to work stably under high voltage environments, secondary control cables usually have good electrical performance and mechanical strength, as well as high anti-interference ability.

[0003] In addition, the design and manufacture of secondary control cables must comply with strict industry standards and safety specifications to ensure reliability and durability in power systems. They usually use special insulation materials and sheaths to resist harsh environmental conditions and chemical corrosion, thereby extending the service life of the cables and reducing maintenance costs. In the process of modernization and intelligentization of power systems, the quality and performance of secondary control cables are crucial to achieving efficient and reliable power transmission and control.

[0004] In the process of installing and maintaining secondary control cables, dragging operations are inevitable. This operation may cause compression and damage to the outer sheath of the cable. Especially during the dragging process, if the cable rubs against the supporting structure such as the cross arm, since the edge of the cross arm is not completely smooth, there may be some sharp protrusions or burrs, which can easily cut or scratch the cable sheath during the friction process. This physical damage will not only reduce the mechanical strength of the cable, but also destroy its insulation performance, thereby increasing the risk of cable failure.

[0005] Furthermore, when the cable needs to make a bend or turn in the channel, if the dragging operation is improper, the friction between the control cable and the sheath will also increase. This local excessive stress may cause the sheath material to crack or peel. Under long-term stress, the cable sheath may gradually lose its protective function, making the internal conductor more susceptible to external environmental influences such as moisture and chemical corrosion, which may eventually lead to a decrease in cable insulation performance, or even a short circuit or other electrical failure.

[0006] Therefore, we propose a supporting device for cable channel installation that can prevent the cable channel from being dragged and cut to solve the above problems. Summary of the invention

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. Among them:

[0022] Figure 3 It is an enlarged schematic diagram of the fixing component structure and its partial structure in the present invention. DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a support device for cable channel installation that prevents cutting by dragging. The cable is supported by a support sleeve 300. During the process of dragging the cable, the support sleeve 300 will rotate accordingly to avoid cutting of the cable.

[0027] Specifically, the angle bracket 100, the shaft body 101 linearly arrayed on the outer wall of the angle bracket 100 and the accommodating cavity 101a integrally formed in the shaft body 101; wherein, the angle bracket 100 is used to support the entire device, and screw holes are also provided on the angle bracket 100, which can be installed on the channel wall by matching bolts.

[0028] A fixing assembly 200 is disposed in the accommodating cavity 101a; wherein the fixing assembly 200 is used to fix the support sleeve 300 so that it cannot rotate, which will be described in detail in subsequent embodiments.

[0029] A support sleeve 300 for installing a cable is sleeved outside the shaft body 101; wherein the inner diameter of the support sleeve 300 is larger than the outer diameter of the shaft body 101. When the cable is displaced outside the support sleeve 300, the support sleeve 300 will move eccentrically outside the shaft body 101.

[0030] It should be noted that in the prior art, angle irons are generally welded on angle brackets to support cables. However, the support sleeve 300 provided by the present invention will not be concentric with the shaft body 101 due to the influence of gravity, regardless of whether a cable is placed on its outer wall.

[0031] When the support sleeve 300 and the shaft body 101 are not on the concentric axis, the non-concentric sleeve design can disperse the tension generated by the cable during movement. That is, when the cable is pulled, the rotation of the sleeve can absorb part of the tension, thereby reducing the direct pressure on the cable.

[0032] Furthermore, the non-concentric sleeve design allows the support device to dynamically adjust when the cable moves. This adjustment can adapt to the direction and speed of the cable movement, reduce the additional pressure caused by the mismatch between the support structure and the cable, and the support sleeve 300 also allows the cable to move within a certain range while maintaining the connection.

[0033] Example 2, reference Figure 1 to Figure 3 , which is the second embodiment of the present invention, is different from the previous embodiment in that a fixing assembly 200 is provided to fix the supporting sleeve 300 when the cable is in place or does not need to be dragged, thereby optimizing the stability of the cable during installation.

[0034] Specifically, the fixing assembly 200 includes a pull rod 201 movably disposed in the accommodating cavity 101a, and a movable channel 101b communicating with the accommodating cavity 101a is provided in a circumferential array on the outer wall of the shaft body 101. In this embodiment, the number of movable channels 101b is 4, and the more the number of movable channels 101b is, the better the fixing effect of the support sleeve 300 is.

[0035] The fixing assembly 200 further includes a support plate 201a slidably connected to the inner wall of the movable channel 101b, and a connecting rod 201a-1 is hingedly connected to the outer wall of the support plate 201a. The connecting rod 201a-1 is hingedly connected to the pull rod 201 at one end away from the support plate 201a, and a receiving groove 201a-2 for connecting with the connecting rod 201a-1 is also provided on the outer wall of the pull rod 201. The movable channel 101b provides a movement stroke of the support plate 201a. In the initial state, the support plate 201a does not protrude from the shaft body 101. When the pull rod 201 moves, each support plate 201a will move synchronously and protrude from the surface of the shaft body 101 to support and fix the inner wall of the support sleeve 300.

[0036] It should be noted that, in order to further optimize the fixing effect of the support plate 201 a , a buffer layer made of rubber is further provided on the outer wall of the support plate 201 a to increase the friction between the support plate 201 a and the support sleeve 300 .

[0037] A clamping groove 300 a is formed on the end surface of the supporting sleeve 300 , and a positioning rod 202 is disposed at one end of the pull rod 201 .

[0038] The outer wall of the positioning rod 202 is provided with a positioning groove 202a, the inner wall of the positioning groove 202a is slidably provided with a positioning block 202a-1, and the first support rod 203 is rotatably provided in the positioning groove 202a. A second elastic member is also provided in the positioning groove 202a, and when the positioning block 202a-1 is displaced, the second elastic member will be deformed.

[0039] A transmission channel 203a is provided through the outer wall of the first support rod 203, and a second support rod 203a-1 is rotatably provided in the transmission channel 203a. The second support rod 203a-1 is rotatably connected to the positioning block 202a-1 at one end away from the first support rod 203. A positioning wheel 204 that can cooperate with the positioning groove 202a is provided at one end of the first support rod 203. When the positioning wheel 204 is located in the accommodating cavity 101a, the second elastic member is in a stressed state, and once the positioning wheel 204 is separated from the accommodating cavity 101a, the positioning wheel 204 will quickly move away from the positioning rod 202 under the support of the second support rod 203a-1, the first support rod 203 and other components.

[0040] In summary, when the cable is installed or no longer needs to be dragged, the staff can pull out the positioning rod 202 and drive the pull rod 201 to move. The movement of the pull rod 201 will lift the support plate 201a through the connecting rod 201a-1. Similarly, each support plate 201a moves synchronously to lift the support sleeve 300, and the friction between the two will fix the support sleeve 300.

[0041] It should be noted here that the fixing of the support sleeve 300 will make it concentric with the shaft 101, that is, the support sleeve 300 will undergo a vertical height change. This height change will allow the cable to have a certain tension after laying to ensure that it will not vibrate or be damaged due to being too loose during operation.

[0042] At this time, the positioning wheel 204 will also move out of the accommodating cavity 101 a , and the positioning wheel 204 can be brought into contact with the slot 300 a on the supporting sleeve 300 , thereby completing the position limiting of the pull rod 201 after it is pulled out.

[0043] It should be noted that the positioning rod 202 can rotate within a certain range at one end of the pull rod 201 to ensure that the positioning wheel 204 can enter the slot 300 a , but the pull rod 201 cannot rotate.

[0044] Example 3, reference Figure 1 to Figure 3 , which is the third embodiment of the present invention. Different from the previous embodiment, some adaptive adjustments are provided to meet the working requirements of the above components.

[0045] Specifically, the end surface of the positioning rod 202 is fixed with a fixing plate 301 by bolts, and the end surface of the fixing plate 301 is provided with a pull ring 301a, and the end surface of the fixing plate 301 is detachably provided with an arc-shaped clamping plate 302. In order to further optimize the stability of the fixing of the pull rod 201 after being pulled out, the arc-shaped clamping plate 302 can be detached and inserted between the fixing plate 301 and the supporting sleeve 300.

[0046] The pull ring 301a can facilitate the staff to control the positioning rod 202.

[0047] A buffer seat 101a-1 is provided in the accommodating cavity 101a, and the inner wall of the buffer seat 101a-1 is movably connected to the pull rod 201. A first elastic member 101a-2 is provided between the pull rod 201 and the buffer seat 101a-1. The first elastic member 101a-2 is a tension spring, and when the pull rod 201 is displaced in the buffer seat 101a-1, the first elastic member 101a-2 is deformed, thereby providing a certain preload force.
