Description

Technical Field

[0001] This application relates to the field of safety protection technology for power transmission tower construction, and in particular to a protective device for power transmission tower construction. Background Technology

[0002] With the accelerated construction of ultra-high voltage power grids, the height of transmission towers generally exceeds 50 meters, which places higher demands on construction safety. Traditional scaffolding protection has many shortcomings, such as long construction periods and high costs.

[0003] Currently, traditional solutions include full-coverage protection for steel pipe scaffolding, speed-delay automatic controllers combined with full-body safety belts, and folding fall arrest nets. While steel pipe scaffolding boasts high load-bearing capacity, its time-consuming assembly and high material wastage rate make it unsuitable for efficient construction environments. Speed-delay automatic controllers combined with safety belts effectively ensure worker safety, but while providing vertical protection, they struggle to address the risk of falls in the horizontal direction or at intersections of inclined members. Folding fall arrest nets, although quick to deploy, are prone to tipping over in winds of force 6 or higher, significantly reducing their protective effectiveness.

[0004] Existing protective devices cannot be fixed according to the tilt angle of the tower, and cannot provide sufficient stability. This can easily lead to an unstable connection between the protective device and the tower, thereby reducing the overall safety and stability. Utility Model Content

[0005] In order to address the problem that existing protective devices for tower construction, due to their inherent design characteristics, cannot be fixed according to the tower's tilt angle, thus failing to provide sufficient stability and easily leading to an unstable connection between the protective device and the tower, thereby reducing overall safety and stability, this application provides a protective device for tower construction.

[0006] The protective device for tower construction provided in this application adopts the following technical solution: it includes a first support column, a second support column opposite to the first support column, lifting lugs respectively installed at the four corners of the first and second support columns, a first clamp installed on one side of the first support column, a second clamp installed on one side of the second support column, an adjustment component for adjusting the first and second clamps, a connecting beam installed between the first and second support columns, and a protective component suspended from the lower end face of the connecting beam. By adopting the above technical solution, the device is first hoisted onto the tower using lifting lugs. Then, the distance between the first and second clamps is adjusted using an adjusting assembly to accommodate the tower's tilt. The tower is then secured using the first and second clamps. A connecting beam connects the two support columns, enhancing the fixation effect, while a protective assembly is installed below the connecting beam to provide cushioning in the event of falling debris, effectively protecting the tower structure.

[0007] As a preferred embodiment, the inner sides of the first clamp and the second clamp are respectively provided with "V" shaped grooves, and the inner walls of the first clamp and the second clamp are respectively provided with protective pads.

[0008] By adopting the above technical solution, the "V"-shaped grooves set on the inner sides of the first clamp and the second clamp can effectively increase the contact area between them and the tower body, improve the fastening and stability, and prevent the tower body from sliding under force; while the protective pad set on the inner wall can form a protective layer between the clamp and the tower body, preventing the clamp from directly contacting the tower body and causing damage, and also increasing the reliability of the tower body fixing.

[0009] As a preferred embodiment, the protective pad is made of rubber and has a Shore hardness of 65-70.

[0010] By adopting the above technical solutions, the rubber protective pads have good elasticity and wear resistance, and a Shore hardness of 65-70, which means that while maintaining a certain hardness, they have good cushioning performance and can effectively absorb impact and vibration.

[0011] As a preferred embodiment, the adjustment assembly includes a first support rod fixedly connected to the first clamp, a first traction rod hinged to the first support rod, a second support rod fixedly connected to the second clamp, a second traction rod hinged to the second support rod, a push seat hinged to the other end of the first and second traction rods, a plunger pump connected to the push seat, and a mounting seat for fixing the plunger pump. A rotating pin is provided between the first and second support rods and the first and second support columns, respectively. Both ends of the rotating pin are fixedly connected to the first and second support columns, and the rotating pin is rotatably connected to the first and second support columns.

[0012] By adopting the above technical solution, the first support rod and the second support rod are connected to the first support column and the second support column through a rotating pin, and can rotate relative to the support column to adjust the position of the equipment; the first traction rod and the second traction rod are connected to the first support rod and the second support rod through a hinge; the push seat is connected to the free end of the first traction rod and the second traction rod, and is used to drive the first traction rod and the second traction rod to change their angle; the plunger pump is connected to the push seat and fixed by the mounting seat, and is used to generate thrust to push the push seat; the mounting seat is used to fix the plunger pump and ensure its stable operation.

[0013] As a preferred embodiment, the system also includes a hydraulic lock connected to the plunger pump, wherein the hydraulic lock is configured as HSGK-08 type.

[0014] By adopting the above technical solution, the plunger pump is responsible for providing power, while the HSGK-08 hydraulic lock ensures that pressure can be reliably locked or released when it is necessary to maintain pressure or restrict flow, thereby improving the safety and reliability of the system.

[0015] As a preferred embodiment, the protective component includes a support frame, a first protective net disposed within the support frame, and a second protective net disposed opposite to the first protective net. The first protective net is woven from 8 strands of Φ6mm stainless steel wire with a mesh size ≤50×50mm, and the second protective net is made of aluminum honeycomb core material.

[0016] By adopting the above technical solution, the support frame is mainly used to fix and protect the entire protective assembly, ensuring its stable installation in the protected location and preventing external objects from being ejected from the protected area. The first protective net is made of 6mm diameter stainless steel wire, with each wire twisted and woven together, and the mesh size controlled within 50×50mm. Its main function is to undergo plastic deformation upon impact, absorbing 60% of the kinetic energy. The second protective net is made of aluminum honeycomb core material, which collapses upon impact, extending the impact buffer time to 0.3 seconds, further absorbing impact energy and providing additional cushioning. When an object impacts between the first and second protective nets, their synergistic effect effectively reduces kinetic energy and extends the buffer time, thereby protecting the target object from impact damage.

[0017] As a preferred embodiment, pressure sensors are respectively provided on the inner sides of the first clamp and the second clamp, and the signal output terminal of the pressure sensor is electrically connected to the signal input terminal of the plunger pump.

[0018] By adopting the above technical solution, the output pressure of the plunger pump reaches 6MPa, ensuring that the first and second clamps fit snugly against the outer periphery of the tower body. The first and second clamps are responsible for fixing and supporting the tower body, respectively. A pressure sensor installed inside monitors the contact pressure between the clamps and the outer periphery of the tower body. The plunger pump receives the signal from the pressure sensor through its signal input terminal and outputs sufficient hydraulic pressure when the pressure reaches 6MPa, ensuring that the first and second clamps fit tightly against the outer periphery of the tower body, thereby ensuring the stability and safety of the tower body. When the pressure sensor detects that the pressure between the clamps and the tower body reaches 5MPa, it triggers a hydraulic lock connected to the plunger pump, locking the pressure between the clamps and the tower body and preventing loosening of the clamps due to external pressure changes or other reasons.

[0019] In summary, this application includes the following beneficial technical effects: 1. This technology mainly consists of a first support column, a second support column, lifting lugs, a first clamp, a second clamp, an adjustment assembly, a connecting beam, and a protective assembly. The first and second support columns provide stable support for the overall device, while the lifting lugs facilitate the installation of the protective device at the target location using lifting equipment; 2. The adjustment component allows for flexible adjustment of the distance between the first and second clamps, thus adapting to tower structures with different tilt angles and ensuring efficient and reliable fixing; 3. The connecting beam links the first and second support columns, enhancing the overall structural stability; 4. The protective components are located below the connecting beam and can effectively buffer falling debris, preventing it from directly impacting the tower structure and thus protecting the tower's safety.

The first support column 101 and the second support column 1021 provide stable support for the overall device, while the lifting lug 411 facilitates the installation of the protective device at the target location using lifting equipment. The adjustment assembly allows for flexible adjustment of the distance between the first clamp 21 and the second clamp 22 to adapt to tower structures with different inclination angles, ensuring efficient and reliable fixing. The connecting beam 103 connects the first support column 101 and the second support column 1021, enhancing the stability of the overall structure. The protective assembly 3 is located below the connecting beam 103 and can effectively buffer falling debris, preventing it from directly impacting the tower structure, thereby protecting the tower's safety. The working principle is as follows: First, the device is hoisted onto the tower using the lifting lug 411. Then, the adjustment assembly is used to adjust the distance between the first clamp 21 and the second clamp 22 to adapt to the tower's inclination, and the tower is fixed using the first clamp 21 and the second clamp 22. The connecting beam 103 connects the first support column 11 and the second support column 12 to enhance the fixing effect, while the protective component 3 is installed below the connecting beam 103 to provide a buffer when debris falls, effectively protecting the tower structure.

[0024] Please refer to the details. Figure 1 and Figure 2 The inner sides of the first clamp 21 and the second clamp 22 are respectively provided with "V" shaped grooves, and the inner walls of the first clamp 21 and the second clamp 22 are respectively provided with protective pads. The "V" shaped grooves provided on the inner sides of the first clamp 21 and the second clamp 22 can effectively increase the contact area between the clamp and the tower body, improve the fastening and stability, and prevent the tower body from sliding under force. The protective pads provided on the inner walls can form a protective layer between the clamp and the tower body, preventing the clamp from directly contacting the tower body and causing damage, and also increasing the reliability of the tower body fixing.

[0025] Please refer to the details. Figure 2 , Figure 3 and Figure 4 The protective pad is made of rubber with a Shore hardness of 65-70. The rubber protective pad has good elasticity and wear resistance. The Shore hardness of 65-70 means that while maintaining a certain hardness, it has good cushioning performance and can effectively absorb impact and vibration.

[0026] Please refer to the details. Figure 1 , Figure 3 and Figure 4The adjustment assembly includes a first support rod 5211 fixedly connected to the first clamp 21, a first traction rod 521 hinged to the first support rod 5211, a second support rod 5221 fixedly connected to the second clamp 22, a second traction rod 522 hinged to the second support rod 5221, a push seat 51 hinged to the other end of the first traction rod 521 and the second traction rod 522, a plunger pump 42 connected to the push seat 51, and a mounting seat 41 for fixing the plunger pump 42. A rotating pin 6 is provided between the first support rod 5211 and the second support rod 5221 and the first support column 101 and the second support column 1021, respectively. Both ends of the rotating pin 6 are fixedly connected to the first support column 101 and the second support column 1021, respectively. Support column 101 and second support column 1021 are rotatably connected. First support rod 5211 and second support rod 5221 are connected to first support column 101 and second support column 1021 through rotating pin 6, and can rotate relative to the support column to adjust the position of the equipment. First traction rod 521 and second traction rod 522 are connected to first support rod 5211 and second support rod 5221 through hinge. Push seat 51 is connected to the free ends of first traction rod 521 and second traction rod 522, and is used to drive the first traction rod 521 and second traction rod 522 to change the angle. Plunger pump 42 is connected to push seat 51 and fixed by mounting seat 41, and is used to generate thrust to push push seat 51. Mounting seat 41 is used to fix plunger pump 42 to ensure its stable operation. In terms of working principle, by adjusting the angle of the first traction rod 521 and the second traction rod 522, the thrust generated by the plunger pump 42 is transmitted to the first support rod 5211 and the second support rod 5221 through the push seat 51, thereby realizing the position adjustment of the tower body fixed by the first clamp 21 and the second clamp 22, thus meeting the requirements of tower bodies that are adapted to different tilt angles.

[0027] Please refer to the details. Figure 2 , Figure 3 and Figure 4 It also includes a hydraulic lock connected to the piston pump 42, which is configured as an HSGK-08 type hydraulic lock. The piston pump 42 is responsible for providing power, while the HSGK-08 type hydraulic lock ensures that pressure can be reliably locked or released when it is necessary to maintain pressure or restrict flow, thereby improving the safety and reliability of the system.

[0028] Please refer to the details. Figure 2 , Figure 3 and Figure 4The protective component 3 includes a support frame 31, a first protective net 321 disposed within the support frame 31, and a second protective net 322 disposed opposite to the first protective net 321. The first protective net 321 is woven from 8 strands of Φ6mm stainless steel wire with a mesh size ≤50×50mm. The second protective net 322 is made of aluminum honeycomb core material. The support frame 31 is mainly used to fix and protect the entire protective component 3, ensuring its stable installation in the protected location and preventing external objects from being ejected from the protected area. The first protective net 321 is made of 6mm diameter stainless steel wire, with each wire twisted and woven together, and the mesh size controlled within 50×50mm. Its main function is to undergo plastic deformation upon impact, absorbing 60% of the kinetic energy. The second protective net 322 is made of aluminum honeycomb core material, which collapses upon impact, extending the impact buffer time to 0.3 seconds, further absorbing impact energy and providing additional cushioning effect. When an object impacts between the first protective net 321 and the second protective net 322, the two work together to effectively reduce kinetic energy and extend the buffer time, thereby protecting the target object from impact damage.

[0029] Please refer to the details. Figure 1 , Figure 2 and Figure 3 Pressure sensors are respectively installed on the inner sides of the first clamp 21 and the second clamp 22, and the signal output terminals of the pressure sensors are electrically connected to the signal input terminal of the plunger pump 42. The output pressure of the plunger pump 42 reaches 6MPa, causing the first clamp 21 and the second clamp 22 to adhere to the outer periphery of the tower body. The first clamp 21 and the second clamp 22 are responsible for fixing and supporting the tower body, respectively. The pressure sensors installed on the inner sides are used to monitor the contact pressure between the clamps and the outer periphery of the tower body. The plunger pump 42 receives the signal transmitted by the pressure sensor through the signal input terminal, and outputs sufficient hydraulic pressure when the pressure reaches 6MPa, so that the first clamp 21 and the second clamp 22 can adhere tightly to the outer periphery of the tower body, thereby ensuring the stability and safety of the tower body. When the pressure sensor detects that the pressure between the first clamp 21 and the second clamp 22 and the tower body reaches 5MPa, it will trigger the hydraulic lock connected to the plunger pump 42 to lock the pressure between the clamps and the tower body, preventing the clamps from loosening due to external pressure changes or other reasons. The overall working principle is as follows: the pressure sensor monitors the pressure changes between the first clamp 21 and the second clamp 22 and the tower body, the plunger pump 42 provides hydraulic pressure to ensure the clamps are tight, and the hydraulic lock will lock the clamps when the pressure reaches a specific value, ensuring the stability and safety of the tower body under various working conditions.

[0030] The implementation principle of the protective device for tower construction in this application embodiment is as follows: In use, the device is first hoisted onto the tower using the hoisting lug 411. Then, by adjusting the angles of the first traction rod 521 and the second traction rod 522, the thrust generated by the plunger pump 42 is transmitted through the push seat 51 to the first support rod 5211 and the second support rod 5221, thereby adjusting the position of the tower body fixed by the first clamp 21 and the second clamp 22 to meet the requirements of tower bodies with different inclination angles. The pressure sensor monitors the first clamp... The pressure changes between the first and second clamps 21 and the tower body are controlled by hydraulic pressure provided by the plunger pump 42 to ensure the clamps are secure. A hydraulic lock will lock the clamps when the pressure reaches a specific value, ensuring the stability and safety of the tower body under various working conditions. The connecting beam 103 connects the first support column 11 and the second support column 12. The first protective net 321 is made of 6mm diameter stainless steel wire, with each wire twisted and woven together. The mesh size is controlled within 50×50mm. Its main function is to undergo plastic deformation upon impact, absorbing 60% of the kinetic energy. The second protective net 322 is made of aluminum honeycomb core material. Upon impact, it collapses, extending the buffer time to 0.3 seconds, further absorbing impact energy and providing additional cushioning. When an object impacts between the first and second protective nets 321 and 322, their synergistic effect effectively reduces kinetic energy and extends the buffer time, thereby protecting the target object from impact damage.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
