Description

Technical Field

[0001] The invention relates to the field of electric power equipment, in particular to a low-voltage overhead cable lead rope traction device. Background Art

[0002] In today's power supply system, the low-voltage overhead cable transformation project plays a vital role. With the continuous development and expansion of cities and the continuous growth of electricity demand in rural areas, higher requirements are placed on the performance and reliability of low-voltage overhead cables. On the one hand, many old urban areas have problems such as aging of low-voltage overhead cables and insufficient capacity. The environment of these old communities is complex, with dense buildings and narrow roads, which brings great challenges to the cable transformation project. In addition, natural obstacles such as rivers also bring technical difficulties to cable crossing. There are two main ways to place the traditional low-voltage overhead cable lead rope. One is the manual traction method. When the ground traction corridor is flat and unobstructed, without obstacles such as crowds and busy streets, the next section of the lead rope is thrown from the pole towers at both ends in the middle of the corridor. The ground personnel pull it together, tie it together and tie it firmly. After tightening it from the pole towers on both sides, it is fixed on the steel strand to pull the overhead cable. The second is the bamboo pole crossing method. When there are obstacles such as ditches, pits, and farmlands in the ground traction corridor, a lead rope is lowered from one side of the pole tower, and the lead rope is picked up with a bamboo pole to cross obstacles such as ditches, pits, and farmlands. However, the traditional method of placing the lead rope has obvious drawbacks when crossing ground obstacles. The placement of the lead rope between two towers is generally no more than 70 meters, and it takes an average of 120 minutes, which greatly leads to slow progress of the project. Due to the slow progress of the project, the low voltage situation in the substation area is difficult to be alleviated in time, which is easy to cause user complaints and have a negative impact on the company's benchmarking with peers. Therefore, it is urgent to develop an efficient low-voltage overhead cable lead rope traction device. Summary of the invention

[0003] The object of the present invention is to provide a low-voltage overhead cable rope traction device, through which the pull rod is pulled to drive the wheel seat to rise, so that the driven wheel is away from the driving wheel, and the steel strand is placed in the hollow warehouse position passing through the side of the support plate, and the cable traction is completed under the drive of the motor assembly to solve the above-mentioned problem.

[0004] To achieve the above object, the present invention provides the following technical solutions: A low-voltage overhead cable lead rope traction device comprises a support plate which provides a stable support structure for the entire traction device.

[0005] The upper and lower ends of the side of the support plate are respectively fixedly installed with an upper support seat and a lower support seat. The upper support seat and the lower support seat are L-shaped, and are surrounded by the support plate to form a hollow warehouse that penetrates the side. On the one hand, this structure provides an installation position for other components. On the other hand, the design of the hollow warehouse can reduce the overall weight of the device, and it also makes it easy for the steel wire rope to be inserted between the driven wheel and the driving wheel from the hollow position.

[0006] A handle is fixedly installed on the top of the upper support seat. A pair of sliding rods are fixedly arranged in parallel on the inner side of the handle, and the two ends of the sliding rods are respectively fixedly connected to the inner side of the handle and the top of the upper support seat, and the pair of sliding rods are slidably fitted with a pull rod, and the pull rod and the sliding rod of the handle are fitted with a spring, and the upper and lower ends of the spring are respectively fixedly connected to the inner side of the handle and the upper side of the pull rod, and a pair of pulling shafts extend downward from the lower end of the pull rod, and the function of this part is to adjust the position of the driven wheel by moving the pull rod up and down, so as to facilitate the steel strand to be clamped between the driven wheel and the driving wheel. The spring plays a role of buffering and resetting.

[0007] The pulling shaft slides through the upper support seat, and a wheel seat is fixedly installed at its bottom. The side plate of the wheel seat is rotatably installed with a driven wheel, and a U-shaped card slot is fixedly installed on the front and rear sides of the driven wheel on the bottom plate of the wheel seat, and the opening of the U-shaped card slot faces downward; the driven wheel cooperates with the driving wheel, and the driving wheel is driven to rotate through the motor assembly, thereby driving the steel strand to move and realize the traction of the cable guide rope. When the driven wheel and the driving wheel touch each other, the U-shaped card slot crosses each other to form a circular hole, which restricts the steel strand in the circular hole to prevent the steel strand from running away.

[0008] The driving wheel is rotatably mounted on the inner side of the side plate of the lower support seat, and a U-shaped slot is fixedly mounted on the bottom plate of the lower support seat at the front and rear sides of the driving wheel, and the opening of the U-shaped slot faces upward.

[0009] A power compartment is arranged on the outer side of the side plate of the lower support seat, and a motor assembly and a battery assembly are arranged inside the power compartment. The motor assembly provides power for the traction device, and the battery assembly provides power for the motor assembly.

[0010] A counterweight bin is fixedly arranged on the support plate on the opposite side of the power bin, symmetrically to the position of the power bin. A counterweight block is placed inside the counterweight bin. The weight of the counterweight block is the sum of the weights of the motor assembly and the battery assembly, which plays a role in balancing the center of gravity of the device and making the device more stable during operation.

[0011] The front and rear sides of the lower support seat are respectively equipped with a steel tail ring and a cable lead rope clamping structure. The steel tail ring includes a locking buckle, which locks the steel tail ring into a steel ring. The steel ring is fitted on the steel strand. After the device falls, the steel tail ring is used to suspend the device for protection, and the device is recovered through the steel tail ring. The cable lead rope clamping structure is relatively installed through a pair of arc components to form an internal elliptical space. Bolts are used to fix the two sides of the arc component to clamp the cable to ensure that the cable will not loosen or fall off during the traction process.

[0012] The motor assembly includes a remote control module, which is wirelessly connected to a remote controller, making it convenient for an operator to remotely control the start and stop of the device.

[0013] The motor component is provided with a current setting protection device, the current setting protection device sets the short-circuit current to 50A, the current setting protection constant is set to 50A, and the delay is 0S, which plays a role in protecting the motor component and preventing the motor from being damaged due to excessive current.

[0014] The device is provided with a color-changing safety warning light strip on the outside, which flashes red during the towing process to remind people around to pay attention to safety and avoid accidents.

[0015] The device is made of galvanized sheet material, has the characteristics of rust resistance and corrosion resistance, and improves the service life of the device.

[0016] The device pulls the pull rod to slide upward on the sliding rod and compress the spring. The pulling shaft at the lower end of the pull rod drives the wheel seat to rise, so that the driven wheel is away from the driving wheel. At this time, the steel strand is placed from the hollow position of the side of the support plate, which is located between the driven wheel and the driving wheel. After the pull rod is released, the pull rod moves downward under the reset action of the spring, driving the driven wheel close to the driving wheel, and clamping the steel strand between the driven wheel and the driving wheel. One end of the cable clamp is clamped by the cable lead rope clamping structure.

[0017] Then, the motor assembly located in the power compartment outside the side plate of the lower support seat starts to work under the power supply of the battery assembly. The motor assembly drives the driving wheel to rotate. Since the steel strand is clamped between the driven wheel and the driving wheel, the rotation of the driving wheel drives the steel strand to move, thereby realizing the traction of the cable guide rope. When the driven wheel touches the driving wheel, the U-shaped grooves on the bottom plate of the wheel seat intersect with each other to form a circular hole, which confines the steel strand in the circular hole and effectively prevents the steel strand from running away.

[0018] At the same time, in order to ensure the stability of the device during operation, a counterweight compartment is set on the support plate on the opposite side of the power compartment. The weight of the counterweight placed inside is equal to the sum of the weight of the motor assembly and the battery assembly, which plays a role in balancing the center of gravity of the device.

[0019] During the operation of the device, the color-changing safety warning light installed on the outside flashes red to remind people around to pay attention to safety and avoid accidents. If the device falls accidentally, the steel tail ring installed on the front and rear sides of the lower support seat can play a protective role. The locking buckle of the steel tail ring locks it into a steel ring, which fits on the steel strand, suspends the device to prevent it from falling further, and the device can be recovered through the steel tail ring.

[0020] In addition, the remote control module of the motor assembly can be wirelessly connected to the remote control, which is convenient for the operator to remotely control the start and stop of the device. The motor assembly is also equipped with a current setting protection device. When the current reaches the set short-circuit current of 50A, the protection device is activated to prevent damage to the motor due to excessive current.

[0021] The cable rope clamping structure consists of a pair of arc-shaped components installed relatively to form an internal elliptical space, which is fixed on both sides of the arc-shaped components by bolts to clamp the cable to ensure that the cable will not loosen or fall off during the traction process.

[0022] In summary, the low-voltage overhead cable rope pulling device realizes efficient, safe and stable cable rope pulling work through the coordinated action of various components.

[0023] Compared with the prior art, the present invention has the following beneficial effects: Driven by a motor, the device can quickly pull steel strands and cable ropes, greatly shortening the operation time and speeding up the progress of low-voltage overhead cable reconstruction projects. It helps to promptly alleviate low voltage conditions in the substation area, reduce user complaints, and improve the company's performance against peers.

[0024] The color-changing safety warning light strip installed on the outside flashes red during the traction process, which can effectively remind people around to pay attention to safety, avoid accidents, and ensure the safety of people on the construction site.

[0025] The steel tail ring can suspend the device to provide protection after it falls, and facilitate the recovery of the device, reducing the risks and losses caused by the falling of the device.

[0026] The motor assembly is equipped with a current setting protection device to prevent the motor from being damaged due to excessive current, thus improving the operating safety and reliability of the device.

[0027] The handle is designed to make it easy for the operator to carry and move the device.

[0028] The remote control module can be connected to the remote control wirelessly to start and stop the remote control device, making operation more convenient and reducing the operator's working time in dangerous areas.

[0029] The hollow chamber structure surrounded by the upper and lower support seats and the support plate not only provides installation locations for other components, but also reduces the overall weight of the device. At the same time, the counterweight block in the counterweight chamber balances the center of gravity of the device, making the device more stable during operation.

[0030] The U-shaped slot forms a circular hole when the driven wheel touches the driving wheel, which confines the steel strand inside and prevents it from escaping, ensuring the stability of the traction process.

[0031] The device is made of galvanized sheet material, which is rust-proof and corrosion-resistant, and can effectively extend the service life of the device and reduce maintenance costs.

[0032] The device has a unique structure that enables it to be operated with one hand, making it convenient for the operator to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The U-shaped slot 4 with the opening facing downward and the U-shaped slot 4 with the opening facing upward intersect with each other to form a circular hole when the driven wheel 31 touches the driving wheel 31. When the driven wheel 31 and the driving wheel 31 clamp the steel strand, the U-shaped slot can confine the steel strand in the circular hole to prevent the steel strand from escaping.

[0037] The motor assembly 81 includes a remote control module, and the remote control module is wirelessly connected to a remote controller.

[0038] The steel tail ring 6 includes a locking buckle 61, which locks the steel tail ring 6 into a steel ring. The steel ring is fitted onto the steel strand. After the device falls, the steel tail ring 6 is used to suspend the device for protection, and the device is recovered through the steel tail ring 6.

[0039] The motor assembly 81 is provided with a current setting protection device, and the current setting protection device sets the short-circuit current to 50A, the current setting protection constant is set to 50A, and the delay is 0S.

[0040] The device is externally provided with a color-changing safety warning light strip, which flashes red during the traction process to remind people around to pay attention to safety and avoid accidents.

[0041] The cable guide rope clamping structure 7 is relatively installed through a pair of arc-shaped components to form an internal elliptical space, and is fixed by bolts on both sides of the arc-shaped components.

[0045] The following is a specific implementation method of the low-voltage overhead cable rope traction device: First, the operator holds the handle 2 and carries the device to a suitable working position. Check whether the various components of the device are normal. Then, pull the pull rod 23 upward, and the pull rod 23 slides upward on the sliding rod 21 to compress the spring 22. The pulling shaft 24 at the lower end of the pull rod 23 drives the wheel seat 25 to rise, so that the driven wheel 31 is away from the driving wheel 32. Then put the steel strand into the hollow warehouse position that passes through the side of the support plate 1 so that it is located between the driven wheel 31 and the driving wheel 32. Release the pull rod 23, and under the resetting action of the spring 22, the driven wheel 31 approaches the driving wheel 32 to clamp the steel strand.

The motor assembly 81 drives the driving wheel 32 to rotate, driving the steel strand to move, thereby achieving the traction of the cable guide rope.

[0048] During the traction process, the color-changing safety warning light on the outside of the device flashes red to remind people around to pay attention to safety. If the device falls accidentally, the locking buckle 61 of the steel tail ring 6 locks the steel tail ring 6 into a steel ring, which fits on the steel strand, suspends the device for protection, and can be recovered through the steel tail ring 6.

[0049] like Figure 4 As shown, the device is driven by a motor and can quickly pull steel strands and cable ropes, greatly shortening the operation time and speeding up the progress of the low-voltage overhead cable reconstruction project.
