Description

Technical Field

[0001] This utility model relates to the field of power engineering construction technology, and in particular to a wiring device for power engineering construction. Background Technology

[0002] In power engineering construction, cabling devices are key equipment to ensure the efficient and safe laying of cables. With the expansion of power engineering scale and the diversification of cable specifications, the limitations of traditional cabling devices in terms of adaptability, ease of operation, and cable protection are becoming increasingly prominent. Especially in complex construction environments, the diameter, material, and laying path of cables vary greatly, and there is an urgent need for a cabling device that can flexibly adapt to different cable specifications and has efficient clamping function. In addition, the requirements for construction efficiency and safety in power engineering are constantly increasing, and the design of cabling devices must take into account both versatility and reliability to reduce manual intervention and reduce the risk of cable damage. Therefore, developing a new type of cabling device for power engineering construction is of great significance for improving construction efficiency and ensuring cable integrity.

[0003] In existing technologies, the wiring devices commonly used in power engineering construction mostly adopt fixed clamping structures. Their core components are usually composed of a pair of rigid rotating wheels or clamps. The distance between the rotating wheels is fixed by bolts or a manual adjustment mechanism. Such devices rely on manual adjustment of the rotating wheel positions to accommodate different cable diameters. Their transmission methods are mostly gear or screw mechanical structures, using friction to clamp and pull the cable. Some improved devices will add a spring pre-tensioning mechanism, but the spring is only used to provide initial pressure and cannot dynamically adjust the clamping force. In addition, existing devices usually lack a buffer mechanism. When the cable is pulled by external force, the stress is directly transmitted to the clamping components, which can easily cause local stress concentration. Although these structures can meet basic wiring requirements, they are significantly lacking in flexibility and adaptability.

[0004] The main problem with existing cabling devices is their inability to adapt to cables of different specifications, resulting in cumbersome and inefficient cabling operations. Due to the use of fixed clamping structures or limited adjustment ranges, when the cable diameter changes, it is necessary to frequently manually adjust the wheel spacing or even replace special clamps. This not only increases construction time but also easily causes surface damage or insulation layer breakage of the cable due to uneven clamping force. In addition, the rigid design of traditional devices cannot dynamically respond to changes in cable size. During the laying process, the cable may slip due to excessively loose clamping or deform due to excessively tight clamping, which seriously affects the construction quality. This problem is particularly prominent in power engineering, requiring a solution that can automatically adapt to cable specifications and achieve stable clamping. Therefore, a cabling device for power engineering construction is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wiring device for power engineering construction, which aims to improve the problem that traditional wiring devices in the prior art are difficult to adapt to different specifications of cables, resulting in cumbersome wiring operations, low efficiency and easy damage to cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wiring device for power engineering construction, comprising a base, a sliding frame provided on the top of the base, a wire spool provided inside the sliding frame, a motor fixedly connected to the outer wall of the sliding frame, the output end of the motor fixedly connected inside the sliding frame, a fixed frame fixedly connected to the top of the base, a lower rotating wheel provided on the outer wall of the fixed frame, an upper rotating wheel slidably connected inside the fixed frame, a fixed block fixedly connected to the outer wall of the upper rotating wheel, the outer wall of the fixed block slidably connected inside the fixed frame, and a telescopic component provided inside the fixed frame;

[0007] The telescopic assembly includes a sliding rod and a spring sleeved on the outer wall of the sliding rod.

A limit ring is fixedly connected to the outer wall of the sliding rod, and a limit assembly is located inside the base.

[0008] As a further description of the above technical solution:

[0009] One end of the spring is fixedly connected to the top of the fixed block, and the other end of the spring is fixedly connected to the inside of the fixed frame;

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a retaining ball and a limiting block, wherein the side wall of the retaining ball is fixedly connected to the outer wall of the limiting block;

[0012] As a further description of the above technical solution:

[0013] A hollow column is fixedly connected inside the base, and a locking hole is opened on the outer wall of the sliding frame, and the locking ball engages with the locking hole;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the limiting block is slidably connected to the inside of the hollow column, and the outer wall of the ball is slidably connected to the inside of the hollow column;

[0016] As a further description of the above technical solution:

[0017] A second spring is installed inside the hollow column. One end of the second spring is fixedly connected to the inside of the hollow column, and the other end of the second spring is fixedly connected to the outer wall of the limiting block.

[0018] As a further description of the above technical solution:

[0019] A telescopic rod is provided inside the hollow column. One end of the telescopic rod is fixedly connected to the inside of the hollow column, and the other end of the telescopic rod is fixedly connected to the outer wall of the limiting block.

[0020] As a further description of the above technical solution:

[0021] The base has a sliding groove inside, and the outer wall of the sliding frame is slidably connected to the inside of the base. A rubber block is provided inside the sliding groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the linkage structure of spring 1, sliding rod, fixed block, and upper rotating wheel, when the cable is placed on the surface of the lower rotating wheel, the sliding rod is pulled to make spring 1 store elastic potential energy, which drives the upper rotating wheel to move. After being released, spring 1 releases potential energy to make the upper and lower rotating wheels fit tightly with the cable, thereby achieving the effect of clamping different cables. This solves the problem that traditional wiring devices are difficult to adapt to different specifications of cables, resulting in cumbersome wiring operations, low efficiency, and easy damage to cables, and improves the versatility of the wiring device.

[0024] 2. In this utility model, when the cable is stretched, the tensile force is transmitted to the sliding frame through the cable drum. When the tensile force exceeds a certain level, the locking hole on the outer wall of the sliding frame squeezes the locking ball, causing the locking ball to break free from the restriction of the sliding frame. The sliding frame can then slide within the groove, solving the problem that the cable is prone to breakage due to excessive tensile force and lack of a buffer mechanism, thus improving the safety of the cable during use.

One end is fixedly connected to the top of the fixed block 8, and the other end is fixedly connected to the inside of the fixed frame 5.

[0035] Reference Figures 3-5The limiting component includes a locking ball 15 and a limiting block 16. The locking ball 15 is used to cooperate with the locking hole 19 to limit and fix the sliding frame 2. The side wall is fixedly connected to the outer wall of the limiting block 16. A hollow column 14 is fixedly connected inside the base 1. The hollow column 14 is used to accommodate the limiting component and provide guidance. The outer wall of the sliding frame 2 has a locking hole 19, which is used to cooperate with the locking ball 15 to achieve locking. The locking ball 15 and the locking hole 19 are engaged. The limiting block 16 is used to drive the locking ball 15 to move and transmit the elastic force of the second spring 17. The outer wall of the locking ball 15 is slidably connected to the inside of the hollow column 14. The outer wall of the locking ball 15 is slidably connected to the inside of the hollow column 14. A second spring 17 is provided inside the hollow column 14. 17 is used to provide a reset elastic force and maintain the engagement state of the locking ball 15 and the locking hole 19. One end is fixedly connected to the inside of the hollow column 14, and the other end is fixedly connected to the outer wall of the limiting block 16. A telescopic rod 18 is provided inside the hollow column 14. The telescopic rod 18 is used to limit the movement range of the limiting block 16 and maintain the movement stability.

The rubber block 13 is used to absorb the impact force when the sliding frame 2 moves and provide a buffering effect.

[0036] Working principle: When cable laying is required, the cable is first placed on the surface of the lower rotating wheel 6. The operator pulls the sliding rod 9, compressing the spring 10 to store elastic potential energy, which simultaneously moves the fixed block 8 and the upper rotating wheel 7 upward. After releasing the sliding rod 9, the spring 10 releases its elastic force, pushing the upper rotating wheel 7 downward, which, together with the lower rotating wheel 6, clamps the cable. Due to the elasticity of the spring 10, the device can automatically adapt to cables of different diameters, ensuring that the clamping force is moderate, neither too tight and damaging to the cable, nor too loose and causing slippage. After the motor 4 starts, it drives the cable drum 3 to rotate, driving the cable to be transported smoothly. During normal cable laying, the sliding frame 2 is controlled by the ball clamp 1. 5. The engagement with the locking hole 19 maintains a fixed position to ensure stable cable delivery. When the cable is accidentally pulled, the tension is transmitted to the sliding frame 2 through the cable drum 3. When the tension exceeds the set threshold, the locking ball 15 is squeezed out of the locking hole 19, the sliding frame 2 slides along the slide groove 12, the second spring 17 is compressed, and the rubber block 13 absorbs the impact energy. Through the buffer mechanism, the risk of cable breakage due to sudden force is effectively avoided. When the external force is eliminated, the second spring 17 pushes the limit block 16 to reset, causing the locking ball 15 to re-lock into the locking hole 19 of the sliding frame 2, so that the sliding frame 2 returns to a fixed state. The telescopic rod 18 ensures that the limit block 16 moves in a straight line and maintains the reset accuracy.
