Abstract
Description
Technical Field
[0001] This invention relates to the field of power engineering technology, and in particular to a height-adjustable cable bracket for power design. Background Technology
[0002] Cable laying is a fundamental and crucial construction step in the construction and maintenance of power systems. To ensure neat cable routing, even stress distribution, and to prevent damage to power transmission safety caused by dragging on the ground, excessive bending, or external forces, cable supports are typically used for temporary cable support.
[0003] Traditional cable supports are mostly fixed-height structures with non-adjustable support height, making it difficult to adapt to the diverse needs of different construction environments for cable laying height. Secondly, when faced with cables of different specifications, existing supports lack effective clamping and limiting mechanisms, which can easily lead to cable slippage, displacement, or even detachment, affecting not only construction quality but also potentially causing safety accidents.
[0004] To address these issues, current market-available supports incorporate hydraulic lifting or electric push rod structures. However, these devices rely on external power sources or hydraulic systems, limiting their applicability in complex or power-free operating environments such as the field, tunnels, and substations. Furthermore, their complex structure, high cost, and risks such as oil leaks, motor failures, and control malfunctions pose serious safety hazards. Summary of the Invention
[0005] The technical problem to be solved and the technical task proposed by this invention is to improve and refine existing technical solutions, and to provide a height-adjustable cable bracket for power design, so as to facilitate the fixing and convenient adjustment of the support height for cables of different specifications. To this end, this invention adopts the following technical solution.
[0006] A height-adjustable cable bracket for power design includes: a support frame, a receiving platform disposed on the top working surface of the support frame, a height adjustment mechanism disposed on the receiving platform, and a cable fixing mechanism connected to the telescopic end of the height adjustment mechanism via a working plate; the support frame has a preset load-bearing capacity, capable of supporting the weight of the components on it and various forces generated during operation; the receiving platform has a preset depth and an open top, which is adapted to the size of the working plate; the cable fixing mechanism is symmetrically disposed on both sides of the top working surface of the working plate, and is used to limit and fix cables of different specifications.
[0007] This bracket modularly integrates height adjustment and cable fixing functions, enabling flexible adjustment of cable support height without the need for external power or complex power systems. It can also effectively limit cable movement. With its simple structure and strong adaptability, it is particularly suitable for use in power construction sites without power or in complex environments.
[0008] Furthermore, the support frame is equipped with casters at its four corners at the bottom, and multiple auxiliary mechanisms for auxiliary support are provided on the working surfaces on both sides of the bottom of the support frame. A preset working distance is maintained between the auxiliary mechanisms and the casters. The casters provide excellent mobility for the entire support structure, facilitating rapid transfer between different work positions and improving construction efficiency. Simultaneously, the preset working distance between the auxiliary mechanisms and the casters, along with the adjustable support function of the auxiliary mechanisms themselves, allows the support structure to quickly and stably transition from a mobile state to a fixed support state after being moved to a designated position, effectively preventing slippage during operation and enhancing work stability and safety.
[0009] Furthermore, the receiving platform is equipped with limiting mechanisms at its four corners, and the telescopic ends of the limiting mechanisms are fixedly connected to the working plate. This provides an independent mechanical locking device for the height-adjustable working plate. After the height is adjusted to the correct position, the limiting mechanisms can securely lock the working plate, forming the first safety barrier to prevent accidental descent. Combined with the self-locking characteristics that the height adjustment mechanism itself may possess, this provides double safety assurance, significantly improving the safety of high-altitude cable laying operations.
[0010] Furthermore, the height adjustment mechanism includes a transmission mechanism and a connecting mechanism movably connected to the transmission mechanism; the transmission mechanism is arranged along the transverse direction of the receiving platform and is rotatably connected to the receiving platform, with one end connected to a hand crank. Height adjustment via manual operation with the hand crank does not rely on external power sources such as electricity or hydraulic pressure, avoiding risks such as electric leakage, motor failure, and hydraulic leakage. It is simple and intuitive to operate, highly reliable, and easy to maintain.
[0011] Furthermore, the transmission mechanism includes a double-ended reverse threaded rod and a bearing seat rotatably connected to the double-ended reverse threaded rod; one end of the double-ended reverse threaded rod is rotatably connected to the receiving platform, and the other end passes through the receiving platform and is connected to the hand crank; both ends of the double-ended reverse threaded rod have a first thread and a second thread, respectively, and the first thread and the second thread are threadedly connected to two connecting mechanisms; the bearing seat is fixedly connected to the receiving platform. Utilizing the characteristic that the threads at both ends of the double-ended reverse threaded rod have opposite directions, when the hand crank is turned, the connecting mechanisms on both sides can be synchronously driven to move in opposite directions or in opposite directions, thereby achieving smooth, synchronous, and vertical lifting of the working plate, avoiding jamming and tilting problems caused by unilateral force or asynchronous lifting. The bearing seat ensures smooth transmission and reduces friction and wear.
[0012] Furthermore, each of the connecting mechanisms includes a movable block, connecting arms connected to both ends of the movable block, and ear plates symmetrically arranged on the working surface at the bottom of the working plate; the movable block is threadedly connected to a double-ended reverse threaded rod, and its two ends are connected to the connecting arms via connecting rods; the connecting arms are hinged to the ear plates. This connecting structure is simple and reliable. When the hand crank drives the double-ended reverse threaded rod to rotate, the two movable blocks move in opposite directions. At this time, the connecting arms drive the working plate and the cable fixing mechanism to rise, realizing an efficient and compact force transmission and motion conversion structure.
[0013] Furthermore, the cable fixing mechanism includes a clamping seat and a clamping plate movably connected to the clamping seat; the clamping seat has a wedge-shaped groove, and a rotating shaft is provided on one side of its top, through which the clamping plate is rotatably connected to the clamping seat; a threaded hole is provided on the other side of the top of the clamping seat; a fixing bolt is provided on the clamping plate, which can be threadedly connected to the threaded hole. The wedge-shaped groove design can accommodate cables of different diameters, allowing them to be naturally centered and positioned, thus offering strong versatility; the clamping plate can be flipped open around the rotating shaft, facilitating the insertion and removal of cables, making operation convenient. Tightening the fixing bolt allows for quick and secure clamping of cables of different specifications, solving the problems of traditional brackets being unable to securely fix cables of different specifications and being prone to slippage.
[0014] Furthermore, the limiting mechanism includes a fixed cylinder and a movable plate slidably connected to the fixed cylinder; the fixed cylinder is provided with a positioning pin; the movable plate has multiple limiting holes along its axial direction, and the positioning pin can be inserted into the limiting holes. This provides a simple, reliable, and easily adjustable mechanical limiting solution. The movable plate rises and falls synchronously with the working plate, and the multiple limiting holes on it provide multiple preset locking heights. By inserting the positioning pin into the corresponding height of the limiting hole, a fast and secure mechanical locking can be achieved. The operation is intuitive, the locking status is clearly visible, and the safety factor is high.
[0015] Furthermore, the auxiliary mechanism includes an extension plate, which is threadedly connected to an adjusting rod. One end of the adjusting rod is provided with a stop plate, and the stop plate has anti-slip textures. The contact force between the stop plate and the ground, as well as the support height, are precisely adjusted via a threaded transmission. The adjustment process is smooth and controllable. The anti-slip textures on the stop plate effectively increase friction with the ground, preventing the support from sliding under load. This significantly improves the adjustment accuracy and stability of the auxiliary support, further ensuring the stability of the support under various ground conditions.
[0016] Compared with the prior art, the present invention has the following beneficial effects: (i) The present invention uses a height adjustment mechanism to achieve smooth lifting and lowering of the cable fixing mechanism through a hand crank. No external power supply is required, and the operation is simple. Users can accurately adjust the cable support height according to the on-site construction needs. Furthermore, the cable fixing mechanism can be adapted to different specifications of cable laying operations, significantly improving work efficiency and applicability. (ii) The bottom of the present invention is equipped with casters, which makes the whole device highly mobile and easy to move quickly on the construction site. At the same time, combined with the auxiliary mechanisms on both sides of the bottom, a stable support pad can be formed to quickly switch the device from a mobile state to a fixed state. (iii) The present invention, through the setting of the limiting mechanism, can lock the working plate after it is raised and lowered to a preset height to prevent accidental descent and provide double safety protection for high-altitude cable laying.

[0024] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0025] like Figure 1 , 2 As shown, this embodiment provides a height-adjustable cable bracket for power design, including: a support frame 1, a receiving platform 2 located on the top working surface of the support frame 1, a height adjustment mechanism 4 located on the receiving platform 2, and a cable fixing mechanism 5 connected to the telescopic end of the height adjustment mechanism 4 via a working plate 3; the support frame 1 has a preset load-bearing capacity, capable of supporting the weight of the components on it and various forces generated during operation, ensuring that the entire device remains stable in complex working environments; a groove 8 is formed on it for placing tools required during cable laying; the receiving platform 2 has a preset depth. Furthermore, the top is open, which is compatible with the working size of the working plate 3; the four corners of the receiving platform 2 are equipped with limiting mechanisms 9, the telescopic ends of the limiting mechanisms 9 are fixedly connected to the working plate 3, and the limiting mechanisms 9 play a precise limiting role in the operation of the entire cable support, preventing the working plate 3 from falling unexpectedly; the cable fixing mechanism 5 is symmetrically arranged on both sides of the working surface at the top of the working plate 3, which is used to limit and fix the cable, so that different types of cables can be stably supported and positioned on the working plate 3, preventing the cable from shifting or falling off due to external forces during operation, and effectively ensuring the stability and safety of power transmission. The support frame 1 is equipped with casters 7 at the four corners of its bottom end, and multiple auxiliary mechanisms 6 are provided on the working surfaces on both sides of the bottom end of the support frame 1. A preset working distance is left between the auxiliary mechanisms 6 and the casters 7. The casters 7 are made of high-strength wear-resistant material. At the power construction site, the operator can move the device by simply pushing it, which improves the construction efficiency and convenience. The preset working distance between the auxiliary mechanisms 6 and the casters 7 ensures that the movement of the casters 7 will not affect the auxiliary mechanisms 6, and also ensures that the device can remain stable during use.
[0026] like Figure 2 , 3As shown, the auxiliary mechanism 6 includes an extension plate 601, which is threadedly connected to an adjusting rod 602. One end of the adjusting rod 602 is provided with a stop plate 603, which has anti-slip textures. Once the position of the device is determined, the operator can rotate the adjusting rod 602 to move the stop plate 603 until it is in close contact with the ground. This prevents the device from sliding or shifting when cables are placed or when it is subjected to external forces, providing additional stable support for the cable support and ensuring that it remains stable in various complex working environments, thereby ensuring the safety of cable laying and operation.
[0027] like Figure 3 As shown, the height adjustment mechanism 4 includes a transmission mechanism 401 and a connecting mechanism 402 movably connected to the transmission mechanism 401. The transmission mechanism 401 is arranged along the transverse direction of the receiving platform 2 and is rotatably connected to the receiving platform 2. One end of the transmission mechanism 401 is connected to the hand crank 403. When the operator needs to adjust the height of the device, he or she rotates the hand crank 403. The hand crank 403 drives the transmission mechanism 401 to rotate. The two connecting mechanisms 402 move in the direction of rotation of the threads on the transmission mechanism 401, thereby adjusting the height of the device. This process is simple to operate and does not require external power equipment or additional power source.
[0028] like Figure 4 As shown, the limiting mechanism 9 includes a fixed cylinder 901 and a movable plate 902 slidably connected to the fixed cylinder 901; the fixed cylinder 901 is provided with a positioning pin 904; the movable plate 902 has multiple limiting holes 903 along its axial direction, and the positioning pin 904 can be inserted into the limiting hole 903. After the height of the working plate 3 and the cable fixing mechanism 5 is adjusted, the operator inserts the positioning pin 904 into the corresponding limiting hole 903, thereby fixing the lifting height and position of the working plate 3, ensuring that the cable fixing mechanism 5 can reliably limit and fix the cable at a stable height and position.
[0029] like Figure 5As shown, the transmission mechanism 401 includes a double-ended reverse threaded rod 4011 and a bearing seat 4014 rotatably connected to the double-ended reverse threaded rod 4011. One end of the double-ended reverse threaded rod 4011 is rotatably connected to the receiving platform 2, and the other end passes through the receiving platform 2 and is connected to the hand crank 403. When the operator holds the hand crank 403 and applies torque, the driving force is directly transmitted to the double-ended reverse threaded rod 4011, driving it to rotate around its own axis. The two ends of the double-ended reverse threaded rod 4011 have a first thread 4012 and a second thread 4013, respectively. The first thread 4012 and the second thread 4013 are in opposite directions and are threadedly connected to two connecting mechanisms 402, respectively, realizing the rotational conversion of the transmission mechanism 401. The vertical lifting and lowering motion of the working plate 3 is achieved by: bearing seat 4014 fixedly connected to the receiving platform 2, providing stable support for the double-headed reverse threaded rod 4011 and reducing frictional loss during rotation; the connecting mechanism 402 includes a moving block 4021, a connecting arm 4023 connected to both ends of the moving block 4021, and ear plates 4024 symmetrically arranged on the working surface at the bottom of the working plate 3; the moving block 4021 is threadedly connected to the double-headed reverse threaded rod 4011, and the two moving blocks 4021 are respectively threadedly connected to the first thread 4012 and the second thread 4013 on the double-headed reverse threaded rod 4011, and both ends are connected to the connecting arm 4023 through the connecting rod 4022; the connecting arm 4023 is hinged to the ear plate 4024.
[0030] When adjusting the height of the working plate 3 and the cable fixing mechanism 5, the operator turns the hand crank 403, which drives the double-headed reverse threaded rod 4011 to rotate. At this time, the two moving blocks 4021 move in opposite directions. The connecting arm 4023 drives the working plate 3 and the cable fixing mechanism 5 to rise. At this time, the moving plate 902 moves vertically along the preset trajectory of the fixed cylinder 901. When the height reaches the operator's preset height, the operator stops turning the hand crank 403. Then, the positioning pin 904 is inserted into the limiting hole 903 to limit and fix the working plate 3 and the cable fixing mechanism 5. The limiting mechanism 9 and the double-headed reverse threaded rod 4011 achieve double fixation of the working plate 3 and the cable fixing mechanism 5, preventing accidental descent and providing double safety protection for high-altitude cable laying.
[0031] like Figure 6As shown, the cable fixing mechanism 5 includes a clamping seat 501 and a clamping plate 502 movably connected to the clamping seat 501. A wedge-shaped groove 504 is provided on the clamping seat 501. The wedge-shaped groove 504 can accommodate cables of different diameters. When a cable is placed in the wedge-shaped groove 504, the cable will naturally be positioned due to the wedge shape, finding a relatively stable placement position regardless of the cable's thickness. A rotating shaft 503 is provided on one side of the top of the clamping seat 501. The clamping plate 502 is rotatably connected to the clamping seat 501 via the rotating shaft 503, allowing the clamping plate 502 to rotate flexibly within a certain range. A threaded hole 506 is provided on the other side of the top of the holder 501; a fixing bolt 505 is provided on the clamping plate 502, which can be threadedly connected to the threaded hole 506. A slot with a matching shape is also provided on the opposite side of the wedge-shaped groove 504 provided on the clamping plate 502 and the holder 501; when the operator needs to fix the cable, he puts the cable into the wedge-shaped groove 504, and then rotates the clamping plate 502 to fix the slot on the clamping plate 502 to the cable. Then, he screws on the fixing bolt 505 to tightly engage the fixing bolt 505 with the threaded hole 506, thereby completing the fixing of the cable.
[0032] The above-described specific embodiments of the present invention demonstrate the outstanding substantive features and significant progress of the present invention. Based on the actual needs of use, equivalent modifications in shape, structure, etc., can be made to the present invention, and all such modifications are within the scope of protection of this solution.
