Description

Technical Field

[0001] This application relates to the technical field of cable laying, and in particular to a cable bracket and cable laying method that are convenient and quick to operate. Background Technology

[0002] When laying cables in cable trenches, cable supports are typically installed on the walls of the trenches to support the cables. Besides clamping the cables and improving the reliability of cable fixation, the cable supports also isolate each cable, preventing interference between them. However, the existing cable supports have independently installed clamps. After the cables are laid, each cable's corresponding clamp needs to be closed one by one, requiring each clamp on each cable support to be closed individually. This results in a heavy workload for workers. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient and quick cable bracket and cable laying method, which can solve the above-mentioned problems existing in the prior art.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On the one hand, a convenient and quick-to-operate cable holder is provided, including:

[0006] The main support structure includes vertically connected vertical bars and horizontal bars;

[0007] Multiple wire clamps are spaced apart on the crossbar. Each wire clamp includes a fixed wire clamp and a movable wire clamp. The fixed wire clamp is fixedly installed on the crossbar, and the movable wire clamp is rotatably installed on the fixed wire clamp. The opening and closing of the wire clamp is controlled by the rotation of the movable wire clamp. The movable wire clamp is also connected to a closing torsion spring, which drives the movable wire clamp to rotate in the closing direction.

[0008] The closing control lever includes a main rod and multiple limiting plates disposed on the main rod. Each limiting plate corresponds to one of the wire clamps. The closing control lever has a locked state and an unlocked state. In the locked state, all the limiting plates can limit the corresponding movable wire clamps, locking the wire clamps in the open state. In the unlocked state, all the limiting plates disengage from limiting the movable wire clamps, and the wire clamps can be closed freely. The state of the closing control lever can be switched by rotating or moving the main rod.

[0009] Optionally, the movable clamp includes a clamping part and a handle. The handle includes a support part and a movable part. The middle part of the support part is rotatably connected to the fixed clamp, and one end of the support part is fixedly connected to the clamping part, while the other end is hinged to the movable part. The movable part is used to cooperate with the limiting plate for limiting. The angle at which the movable part can rotate relative to the support part is limited such that: when the closing control lever is in the locked state, during the process of opening the movable clamp, the movable part can rotate relative to the support part, allowing the movable part to pass over the limiting plate. The movable part is restricted by the limiting plate to keep the clamp open, and the movable part cannot rotate relative to the support part to pass over the limiting plate.

[0010] Optionally, the support portion and the movable portion are hinged together by a hinge, and the hinge is installed on the side of the clamp that abuts against the limiting piece to keep the wire clamp in the open state.

[0011] Optionally, the hinge is provided with a reset torsion spring, which is used to drive the movable part to rotate and reset, so that the movable part that has passed the limiting piece returns to the angle that can be limited by the limiting piece.

[0012] Optionally, the main rod is fitted with a limit spring, which is used to drive the main rod to rotate or move toward the locked state.

[0013] Optionally, the main rod switches between the locked state and the unlocked state by rotation; the limiting spring is a torsion spring.

[0014] Optionally, the crossbar is provided with a rotating mounting seat, and the main rod is rotatably mounted on the rotating mounting seat; the two ends of the limiting spring are respectively a first lever and a second lever, and a swing arm is provided on the side of the main rod. The first lever abuts against the rotating mounting seat, and the second lever abuts against the swing arm, so that the limiting spring can drive the main rod to twist.

[0015] Optionally, the crossbar is provided with a plurality of fixed supports corresponding to the wire clamps, and the fixed wire clamps are fixedly installed on the fixed supports.

[0016] Optionally, the fixed support includes a base plate and two vertical plates respectively connected to both ends of the base plate. The vertical plates extend upward, and both ends of the fixed wire clamp are respectively connected to the two vertical plates. The vertical plates are provided with a clearance hole in the middle to allow the main rod to pass through.

[0017] On the other hand, a cable laying method based on the aforementioned convenient and quick-operation cable bracket is provided, including the following steps:

[0018] Fix the vertical rod of the main support body to the wall or column surface, and open all the wire clamps on the horizontal rod;

[0019] Pull the cables and place multiple cables into each of the fixing clamps;

[0020] Once all cables are in place, operate the control lever to the unlocked position to close all the clamps and secure the cables.

[0021] The beneficial effects of this application are as follows: This invention provides a convenient and quick-operating cable bracket and cable laying method. The cable bracket is equipped with multiple clamps for clamping multiple cables, thereby fixing multiple cables separately. Importantly, this solution provides a closing torsion spring on each clamp to drive the clamp to close, and also includes a closing control lever that can simultaneously operate multiple clamps. After placing each cable into its respective clamp, simply twisting or pulling the closing control lever unlocks it, and under the elastic force of the closing torsion spring, all clamps close synchronously. Therefore, this cable bracket solution allows for the synchronous closing of multiple clamps with a simple operation, effectively reducing the workload of workers closing the clamps and improving the efficiency of cable laying.

[0033] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] When laying cables in cable trenches, cable supports are typically installed on the walls of the trenches to support the cables. Besides clamping the cables and improving the reliability of cable fixation, the cable supports also isolate each cable, preventing interference between them. However, the existing cable supports have independently installed clamps. After the cables are laid, each cable's corresponding clamp needs to be closed one by one, requiring each clamp on each cable support to be closed individually. This results in a heavy workload for workers.

[0037] like Figure 1 As shown, this embodiment provides a convenient and quick-to-operate cable bracket, including:

[0038] The main support body 1 includes a vertically connected vertical rod 11 and a horizontal rod 12;

[0039] Multiple wire clamps 2 are spaced apart on the crossbar 12. Each wire clamp 2 includes a fixed wire clamp 21 and a movable wire clamp 22. The fixed wire clamp 21 is fixedly installed on the crossbar 12, and the movable wire clamp 22 is rotatably installed on the fixed wire clamp 21. The opening and closing of the wire clamp 2 is controlled by the rotation of the movable wire clamp 22. The movable wire clamp 22 is also connected to a closing torsion spring 23, which drives the movable wire clamp 22 to rotate in the closing direction.

[0040] The closing control lever 3 includes a main rod 31 and a plurality of limiting pieces 32 disposed on the main rod 31. Each limiting piece 32 is correspondingly disposed to one of the wire clamps 2. The closing control lever 3 has a locked state and an unlocked state. In the locked state, all the limiting pieces 32 can limit the corresponding movable wire clamps 22, so that the wire clamps 2 are locked in the open state. In the unlocked state, all the limiting pieces 32 are released from limiting the movable wire clamps 22, and the wire clamps 2 can be closed freely. The state of the closing control lever 3 can be switched by rotating or moving the main rod 31.

[0041] In this design, the wire clamp 2 includes a movable wire loop 22 that can be opened and closed, and it is connected to a closing torsion spring 23. Figure 1 Taking the angle shown as an example, the movable wire clamp 22 rotates clockwise and opens when it rotates counterclockwise. The closing torsion spring 23 is used to drive the movable wire clamp 22 to rotate in the closing direction. That is, the closing torsion spring 23 will always provide torque to push the movable wire clamp 22 to rotate clockwise. When there is no other external force to limit it, the closing torsion spring 23 will push the movable wire clamp 22 to rotate clockwise to close.

[0042] To facilitate the quick insertion of cables into the fixed clamps 21 during cable laying, all clamps 2 need to be kept open before cable laying. Therefore, this solution is equipped with a closing control lever 3 with multiple limiting plates 32. Each limiting plate 32 is used to restrict the rotation of each movable clamp 22, thereby locking each movable clamp 22 in the open state. Moreover, the closing control lever 3 is rotatable or movable. By rotating or moving the closing control lever 3, all limiting plates 32 can be moved synchronously, causing the limiting plates 32 to release their restriction on each movable clamp 22. After being released from restriction, all clamps 2 will quickly and automatically close under the elastic force of the closing torsion spring 23.

[0043] In summary, the cable support based on this embodiment, which allows for convenient and quick operation, is equipped with multiple clamps 2 for clamping multiple cables, thus securing them individually. Importantly, this design includes a closing torsion spring 23 on each clamp 2 to drive its closure, and a closing control lever 3 capable of simultaneously manipulating multiple clamps 2. After placing each cable into its respective clamp 2, simply twisting or pulling the closing control lever 3 unlocks it, and the clamps 2 close synchronously under the elastic force of the closing torsion spring 23. Therefore, this cable support design allows for the synchronous closure of multiple clamps 2 with a simple operation, effectively reducing the workload of workers closing the clamps and improving cable laying efficiency.

[0044] In one embodiment, reference is made to Figure 4-5 The movable wire clamp 22 includes a wire clamping part 221 and a clamp handle 222. The clamp handle 222 includes a support part 2221 and a movable part 2222. The support part 2221 is rotatably connected to the fixed wire clamp 21 in the middle. One end of the support part 2221 is fixedly connected to the wire clamping part 221, and the other end is hinged to the movable part 2222. The movable part 2222 is used to cooperate with the limiting piece 32 for limiting. The angle at which the movable part 2222 can rotate relative to the support part 2221 is limited such that when the closing control lever 3 is in the locked state, during the process of opening the movable wire clamp 22, the movable part 2222 can rotate relative to the support part 2221, allowing the movable part 2222 to pass over the limiting piece 32. The movable part 2222 is restricted by the limiting piece 32 to keep the wire clamp 2 open, and the movable part 2222 cannot rotate relative to the support part 2221 to pass over the limiting piece 32.

[0045] Specifically, with Figure 4Taking the angle shown as an example, the movable clamp 22 opens by rotating counterclockwise and closes by rotating clockwise. In this design, the clamp handle 222 is configured to include two parts: a support part 2221 and a movable part 2222 that rotate relative to each other. The purpose is to facilitate manual opening and fixing of the clamp 2 at any time. That is, before opening the clamp 2, the closing control lever 3 is in a locked state. When the movable clamp 22 is rotated to open, the movable clamp 22 can also smoothly enter the position restricted by the limiting piece 32. Specifically, during the counter-clockwise opening of the movable clamp 22, when the movable part 2222 contacts the limiting plate 32, the movable part 2222 can rotate clockwise relative to the supporting part 2221, and the movable clamp 22 can continue to rotate counter-clockwise. When the bottom edge of the movable part 2222 is higher than the top of the limiting plate 32, the movable part 2222 can rotate counter-clockwise relative to the supporting part 2221 to reset. After that, the bottom edge of the movable part 2222 will be lower than the bottom of the limiting plate 32, and the movable part 2222 will be restricted to the left side of the limiting plate 32, thus locking the movable clamp 22. Therefore, this solution allows the movable clamp 22 to be opened and locked independently while the closing control lever 3 is in the locked state, making the operation simple and quick. Thus, this solution can simultaneously close multiple clamps 2 with a single operation of the closing control lever 3, and can also open a single clamp 2. This method is convenient for opening one clamp 2 independently during circuit maintenance while keeping the others closed.

[0046] Refer again Figure 4 In the open state, the limiting piece 32 is located on the left side of the handle 222, which can just restrict the entire movable wire clamp 22 from rotating counterclockwise. Therefore, the movable wire clamp 22 can be locked in the open state. In order to ensure the reliability of the locking, it is necessary to ensure that the movable part 2222 that cooperates with the limiting piece 32 is stable and does not move, that is, the movable part 2222 cannot rotate counterclockwise relative to the support part 2221.

[0047] In one embodiment, the support portion 2221 and the movable portion 2222 are hinged by a hinge 2223, and the hinge 2223 is installed on the side of the clamp 222 used to abut against the limiting piece 32 to keep the wire clamp 2 in the open state.

[0048] For ease of explanation, we will also use... Figure 4 For reference, Figure 4With the center clamp 2 in the open state and the entire clamp handle 222 in the upright state, the left side of the clamp handle 222 is the side used to abut against the limiting piece 32 to keep the clamp 2 in the open state. Therefore, the hinge 2223 is installed on the left side of the clamp handle 222. With the hinge 2223 installed in this way, the movable part 2222 can rotate clockwise relative to the support part 2221, but cannot rotate counterclockwise relative to the support part 2221. This just meets the requirement in this solution that when the movable clamp 22 is opened, the movable part 2222 can rotate freely to avoid the limiting piece 32, and after opening, the movable part 2222 can be stably limited by the limiting piece 32.

[0049] In one embodiment, reference is made to Figure 4 The hinge 2223 is provided with a reset torsion spring, which is used to drive the movable part 2222 to rotate and reset, so that the movable part 2222 that has passed the limiting piece 32 returns to the angle that can be limited by the limiting piece 32.

[0050] A reset torsion spring is provided inside the hinge 2223. When the movable part 2222 passes the limiting piece 32, it can automatically push the movable part 2222 to rotate and reset, so that the movable part 2222 can be restricted to the right side of the limiting piece 32.

[0051] Among them, the hinge with integrated torsion spring is existing technology, and will not be elaborated on in this case.

[0052] In one embodiment, reference is made to Figure 3-4 The main rod 31 is fitted with a limiting spring 33, which is used to drive the main rod 31 to rotate or move toward the locked state.

[0053] Specifically, when the main rod 31 switches between the locked and unlocked states by rotation, the limit spring 33 is a torsion spring; when the main rod 31 switches between the locked and unlocked states by movement, the limit spring 33 is a linear spring. Setting the limit spring 33 to drive the main rod 31 to move freely towards the locked state ensures the reliability of locking the wire clamp 2 after it is opened. Furthermore, after unlocking, when the operator releases their grip, the main rod 31 automatically switches back to the locked state. When the wire clamp 2 needs to be opened again, there is no need to operate the closing control lever 3; simply manually flip the movable wire clamp 22 that needs to be opened.

[0054] In one embodiment, the main rod 31 switches between the locked state and the unlocked state by rotation; the limiting spring 33 is a torsion spring.

[0055] The closing control lever 3 is installed using a rotary mounting method, and the end of the closing control lever 3 can be directly twisted, making the operation simple. Preferably, a handle is bent at the end of the main rod 31 for easy manual twisting.

[0056] In one embodiment, combined with Figure 8 The crossbar 12 is provided with a rotating mounting seat 13, and the main rod 31 is rotatably mounted on the rotating mounting seat 13; the two ends of the limiting spring 33 are respectively a first lever and a second lever, and the side of the main rod 31 is provided with a swing rod 311. The first lever abuts against the rotating mounting seat 13, and the second lever abuts against the swing rod 311, so that the limiting spring 33 can drive the main rod 31 to twist.

[0057] A swing arm 311 is provided on the side of the main rod 31, which can cooperate with the second lever of the limiting spring 33 to facilitate the limiting spring 33 to drive the main rod 31 to rotate and reset.

[0058] In one embodiment, the crossbar 12 is provided with a plurality of fixed supports 14 corresponding one-to-one with the wire clamps 2, and the fixed wire clamps 21 are fixedly installed on the fixed supports 14.

[0059] A fixed support 14 is provided on the crossbar 12 to support the fixed wire clamp 21, which can easily and reliably fix the fixed wire clamp 21 and improve the reliability of the wire clamp 2 in supporting the cable.

[0060] In one embodiment, the fixed support 14 includes a base plate 141 and two vertical plates 142 respectively connected to both ends of the base plate 141. The vertical plates 142 extend upward, and both ends of the fixed wire clamp 21 are respectively connected to the two vertical plates 142. The vertical plates 142 are provided with a clearance hole in the middle to allow the main rod 31 to pass through.

[0061] The U-shaped fixed support 14 can provide convenient support and fixation for the arc-shaped fixed wire hoop 21, which facilitates the installation of the main rod 31 and has the advantage of low material consumption.

[0062] On the other hand, a cable laying method based on the aforementioned convenient and quick-operation cable bracket is provided, including the following steps:

[0063] Fix the vertical rod 11 of the main support body 1 to the wall or column surface, and open all the wire clamps 2 on the horizontal rod 12;

[0064] Pull the cables and place multiple cables into each of the fixing clamps 21;

[0065] Once all cables are in place, operate the closing control lever 3 to the unlocked state to close all the cable clamps 2 and secure the cables.

[0066] Based on the cable bracket of this embodiment, the cable laying method of this embodiment has the advantages of simpler operation and higher laying efficiency.
