Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for construction and maintenance of power and communication lines, and specifically relates to a modular cable maintenance suspension support based on a linkage hydraulic air spring. Background Technology

[0002] In the laying, inspection, and maintenance of cable lines, it is often necessary to temporarily lift a section of cable off the ground or its original support to facilitate jointing, troubleshooting, and other operations. Currently, on-site operations mostly rely on general-purpose lifting platforms (such as hydraulic lifting vehicles and scaffolding) or simple supports (such as wooden sticks and steel pipes with ropes). The former is bulky, inconvenient to transport and deploy, and particularly unsuitable for narrow or complex terrain; the latter suffers from insufficient stability, difficulty in height adjustment, insecure cable fixation, and easy damage to the cable insulation. Existing technology lacks a dedicated tool that integrates rapid deployment, stable lifting, reliable self-adaptive clamping, and portability, resulting in low on-site maintenance efficiency and safety risks.

[0003] In view of the above factors, a modular cable maintenance suspension bracket based on a linkage hydraulic air spring is provided as a special lifting bracket for temporary on-site support, lifting and fixing of cables. Summary of the Invention

[0049] The lower support sleeve 3 and the upper support sleeve 303 are integrally welded structures, and the upper transverse connecting plate 308 and the lower transverse connecting plate 312 of the frame are arranged in parallel.

[0050] The upper support column 4 is welded to the top of the upper support sleeve 303.

[0051] The lower end of another upper hydraulic gas spring 6 is hinged to the lower hinge seat 313 of the cylinder body, and the upper end is hinged to the other end of the transverse lower connecting plate 312 of the frame.

[0052] The two sets of hydraulic air springs 6 are equipped with an upper hydraulic air spring adjusting lock 601 and a lower hydraulic air spring adjusting lock 602. The upper hydraulic air spring adjusting lock 601 and the lower hydraulic air spring adjusting lock 602 are connected to the control valve adjusting rod 603 of a linkage control valve 604.

[0053] The upper hydraulic gas spring adjusting cable 601 is led out from the upper adjusting cable through hole 307, and the lower hydraulic gas spring adjusting cable 602 is led out from the lower adjusting cable through hole 311. The upper hydraulic gas spring adjusting cable 601 and the lower hydraulic gas spring adjusting cable 602 are inserted into the axial through hole 704 of one of the hollow stepped double-headed bolts 7, and then their ends are connected to the control valve adjusting rod 603 of the linkage control valve 604.

[0054] The upper hydraulic gas spring adjusting cable 601 and the lower hydraulic gas spring adjusting cable 602 are inserted into the axial through hole 704 of the hollow step double-headed bolt 7. The upper support column 4 is fixedly connected to the horizontal upper connecting plate 308 of the frame and rises and falls together with it.

[0055] The hollow stepped double-ended bolt 7 includes an upper optical shaft 701, an upper nut 702, and an upper threaded section 703. The upper threaded section 703 has a through hole 704, and its lower part is provided with a lower optical shaft 705 and a lower threaded section 706. The lower threaded section 706 is screwed onto the lower nut 707.

[0056] The hollow stepped double-headed bolt 7 passes through the lower optical axis 705 at one end of the lower support sleeve 3, is fitted with the horizontal lower connecting plate 312 of the frame, and then the lower end nut 707 is tightened. On the other end of the double-headed bolt 7, the optical axis 701 is fitted, the horizontal upper connecting plate 308 of the frame is fitted, and then the upper end nut 702 is tightened.

[0057] The main frame 503 of the lifting platform has screw holes 502, and wear-resistant anti-slip pads 501 are fixedly installed on the main frame 503. Several main frames 503 of the lifting platform are provided, and the several main frames 503 of the lifting platform are connected by mortise and tenon joints.

[0058] The cable adaptive clamping mechanism includes a hinged flap 504 on the main frame 503 of the lifting platform. The flap 504 is connected to a pressure plate 506 via a pin 505. The pressure plate 506 is connected to a high-strength nylon soft strip 507. The main frame 503 of the lifting platform is provided with a pressure working surface 508 and a dovetail groove 509. The dovetail groove 509 is connected and engaged with a dovetail tenon 5. A straight slide groove 512 is provided on the main frame 503 of the lifting platform. A slider 510 is embedded in the straight slide groove 512. The sliders 510 are connected to each other via a slider connecting rod 511. The dovetail groove 509 is provided with a dovetail groove positioning hole 513 and is engaged with a dovetail groove positioning knob 514.

[0059] The lifting platform main frame 503 has a dovetail groove 509 on one side, which can be spliced ​​with the dovetail tenon 5 of another identical lifting platform main frame 503 to realize modular expansion of the working area.

[0060] The main frame 503 of the lifting platform has a through hole for installing the clamping plate 506. One end of the high-strength nylon soft strip 507 can be pressed between the clamping plate 506 and the clamping working surface 508, and the other end is connected to the slider connecting rod 511. The size of the soft strip ring can be adjusted by sliding the slider 510 to accommodate cables of different diameters. Then, pressing down the clamping plate 506 can lock the soft strip, forming a flexible wrapping clamp.

[0061] The telescopic leg 103 and telescopic leg 104 are nested telescopic structures. The base 105 is a rubber adsorption base. The dovetail groove 509 and the dovetail tenon 5 are in clearance fit, and positioning and locking are achieved through the dovetail groove positioning knob 514 and the dovetail groove positioning hole 513.

[0062] During operation, place the bracket below or to the side of the cable, and wrap it with high-strength nylon strapping 507 to initially secure the cable. When lifting is required, operate the linkage control valve 604 with one hand. This, along with the valve adjusting rod 603, simultaneously pulls the two adjusting locks, causing the two hydraulic air springs 6 to extend synchronously, pushing the upper transverse connecting plate 308 of the frame relative to the lower transverse connecting plate 312. Due to the constraint of the double-headed bolts 7 and the support sleeve, the entire frame deforms into a parallelogram, thereby driving the upper support column 4 and the main frame 503 of the top lifting platform to rise vertically and smoothly, raising the cable to the required height. Lowering is achieved by reversing the operation.

[0063] An assembly method for a modular cable maintenance suspension support based on a linkage hydraulic gas spring:

[0064] First, assemble the base by attaching the four telescopic legs 103 to the four corners of the base 1 via the feet 105. Then, fit the lower support sleeve 3 onto the lower support column 2, and screw the lower end of the lower support column 2 into the base screw hole 101 of the base 1 and tighten it. Finally, install the plug 302 at the end of the lower support sleeve hole 301.

[0065] The second step is to assemble the parallelogram lifting frame. Take two hollow stepped double-ended bolts 7. Pass the first double-ended bolt 7 through the upper support sleeve hole 304 of the upper support sleeve 303 and the lower support sleeve hole 301 of the lower support sleeve 3. At the end of the double-ended bolt 7 that passes through the lower support sleeve 3, place the lower horizontal connecting plate 312 of the frame on the lower optical shaft 705, and then tighten the lower nut 707. At the other end of the double-ended bolt 7, place the upper horizontal connecting plate 308 of the frame on the upper optical shaft 701, and then tighten the upper nut 702. Install the second double-ended bolt 7 and the upper horizontal connecting plate 308 and the lower horizontal connecting plate 312 of the frame on the other side in the same way.

[0066] The third step is to install the hydraulic air springs and linkage control. The lower ends of the two upper hydraulic air springs 6 are hinged to the lower cylinder hinge seat 313 of the lower transverse connecting plate 312 of the frame, and the upper ends are hinged to the upper cylinder hinge seat 314 of the upper transverse connecting plate 308 of the frame. The upper hydraulic air spring adjusting cable 601 is led out from the upper adjusting cable through hole 307, and the lower hydraulic air spring adjusting cable 602 is led out from the lower adjusting cable through hole 311. These two cables are then inserted together into the axial through hole 704 of one of the hollow stepped double-ended bolts 7, and their ends are connected to the control valve adjusting rod 603 of the linkage control valve 604.

[0067] The fourth step is to install the upper support column and the working platform. The lower end of the upper support column 4 is screwed into the upper support sleeve hole 304 of the upper support sleeve 303 on the side of the horizontal upper connecting plate 308 of the frame. The main frame 503 of the lifting platform is fixed to the top of the upper support column 4 with bolts 102 through the lifting platform screw hole 502 at its bottom. A wear-resistant and anti-slip pad 501 is provided on the pressing working surface 508.

[0068] Fifth step, install the cable clamping assembly, place the slider 510 into the linear groove 512 of the main frame 503, and hinge the clamping plate 506 to the L-shaped flap 504 through the pin 505.

[0069] In field use, move the assembled bracket under the cable to be inspected, adjust the base telescopic legs 103 to stabilize the bracket, open the clamping plate 506, place one end of the high-strength nylon soft strip 507 on the clamping working surface 508, and then press down the clamping plate 506 to initially fix it. Wrap the other end of the nylon soft strip 507 around the cable and hook it into or connect it to the U-shaped ring or connecting part of the slider 510. Depending on the thickness of the cable, slide the slider 510 along the straight groove 512 to make the nylon soft strip 507 wrap around the cable with appropriate tightness. Finally, press down the clamping plate 506 again to firmly press the nylon soft strip 507 onto the clamping working surface 508, completing the cable clamping.

[0070] When it is necessary to raise the cable, the operator turns the linkage control valve 604 to the "raise" position with one hand. The linkage control valve 604, through the control valve adjusting rod 603, simultaneously tightens the two adjusting locks 601 and 602, triggering the two hydraulic air springs 6 to extend smoothly and synchronously. The thrust of the hydraulic air springs 6 pushes the frame's horizontal connecting plate 308 upward. Due to the hinge constraint of the double-headed bolts 7, the entire frame deforms like a parallelogram, thereby vertically lifting the upper support column 4 and the entire work platform unit, smoothly raising the clamped cable to a height convenient for maintenance. After maintenance is completed, the linkage control valve 604 is turned to the "lower" position. The hydraulic air springs 6 slowly retract under control, and the support smoothly descends and resets. If the working area of ​​a single platform is insufficient, the dovetail tenon 5 of another platform of the same model can be aligned with the dovetail groove 509 on the side of this platform and pushed in. Then, the dovetail groove positioning knob 514 is screwed into the insertion positioning hole 513 to achieve rapid splicing and expansion of the platform.
