Description

Technical Field

[0001] The invention relates to the technical field of insulating centipede ladders, in particular to a high-efficiency operating insulating centipede ladder. Background Art

[0002] With the continuous development of my country's economic construction, it is necessary to vigorously carry out the inspection and maintenance of live working. According to incomplete statistics, my country is currently carrying out a large number of inspections and maintenance of live working to improve the reliability of power supply, but the results are not satisfactory in some special terrains. At present, the average time for insulated centipede ladder operation is about 89.38 minutes, of which the average time for personnel displacement is 41.96 minutes, accounting for 73.37% of the total time. The time for the displacement of personnel on the insulated centipede ladder is long, and the small transfer angle makes the transfer time of live working in different spaces long. Through time analysis, it can be seen that the longer the electrician stays on the insulated centipede ladder, the slight impact on the transfer time. Therefore, there is an urgent need for an insulated centipede ladder that can improve work efficiency. Summary of the invention

[0003] The present invention solves the problems of small indexing angle and small contact surface force point of the existing centipede ladder, and provides a high-efficiency working insulating centipede ladder. An operating platform board is quickly installed on the existing centipede ladder, and the rod-shaped horizontal ladder at the top of the rod is replaced with an operating platform board. Shifting operations are performed on the operating platform board to improve working efficiency.

[0004] In order to achieve the above objectives, the following technical solutions are proposed: A high-efficiency insulating centipede ladder comprises an insulating centipede ladder main body and a quick-connect platform, wherein the quick-connect platform is provided with at least one and is quickly connected and fixed on the insulating centipede ladder main body, the quick-connect platform comprises an operating platform plate and a support rod, one end of the operating platform plate is vertically fixed on the insulating centipede ladder main body through a first locking device, the other end of the operating platform plate is rotatably connected to one end of the support rod, the other end of the support rod is rotatably connected to a second locking device, and the first locking device and the second locking device are quickly connected and fixed on the insulating centipede ladder main body.

[0005] The high-efficiency insulating centipede ladder of the present invention comprises an insulating centipede ladder main body and at least one quick-connect platform, wherein the insulating centipede ladder main body comprises an insulating cylinder and a rod-shaped horizontal ladder staggered on both sides of the insulating cylinder, and the quick-connect platform comprises a support rod and an operating platform plate, one end of the operating platform plate is fixed with a first locking device which is quickly connected and fixed on the insulating centipede ladder main body, and the operating platform plate is vertically fixed on the insulating centipede ladder main body through the first locking device, one end of the support rod is rotatably connected to the other end of the operating platform plate, and a second locking device is quickly fixed on the insulating centipede ladder main body, and the second locking device is rotatably connected to the other end of the support rod.

[0006] Since live line operations are required, the operating platform board should meet the requirements of increased area and improved indexable angle performance within a limited space while meeting insulation performance. The operating platform board is designed as an integrated insulation panel of 0.6m×0.21m, using an integrated carbon fiber winding Class III composite material cutting process, which reduces weight while ensuring insulation strength to meet the requirements of increased area.

[0032] Embodiment 1: This embodiment provides an efficient working insulating centipede ladder, referring to Figure 1 , including an insulating centipede ladder main body and at least one quick-connect platform, the insulating centipede ladder main body includes an insulating cylinder and a rod-shaped horizontal ladder staggered on both sides of the insulating cylinder, the quick-connect platform includes a support rod 3 and an operating platform board 1, one end of the operating platform board 1 is fixed with a first locking device 2 quickly fixed on the insulating centipede ladder main body, the operating platform board 1 is vertically fixed on the insulating centipede ladder main body through the first locking device 2, one end of the support rod 3 is rotatably connected to the other end of the operating platform board 1, a second locking device 4 is quickly fixed on the insulating centipede ladder main body, and the second locking device 4 is rotatably connected to the other end of the support rod 3.

[0033] Since live line operations are required, the operating platform board 1 should meet the requirements of increasing the area while meeting the insulation performance requirements, ensuring the performance of increasing the indexable angle within a limited space. The operating platform board 1 is designed as an integrated insulation panel of 0.6m×0.21m, using an integrated carbon fiber winding Class III composite material cutting process, which reduces the weight while ensuring the insulation strength to meet the requirements of increasing the area.

[0034] In order to provide a fulcrum for personnel on the operating platform board 1 and prevent personnel from falling, the present invention provides a rod-shaped guardrail 5 on the operating platform board 1. The guardrail 5 is specifically arranged at one end where the operating platform board 1 is connected to the support rod 3.

[0035] The present invention sets the ratio of the length of the operating platform plate 1 to the length of the support rod 3 so that the ratio ranges from 1 / 2 to The purpose is to make the angle between the operating platform board 1 and the support rod 3 when fixed to the insulating centipede ladder body be between 45° and 60°, thereby ensuring the supporting strength of the support rod 3 and preventing the support rod 3 from being too long and inconvenient to be folded and stored after disassembly.

[0036] The inner side walls of the movable clamp 9 and the fixed clamp 7 of the present invention are fixed with an insulating protective pad 12 by screws. The surface of the insulating protective pad 12 is rough and can provide sufficient friction.

[0037] The invention improves the top of the insulating centipede ladder by installing a quick-connect platform on the top of the insulating centipede ladder, thereby improving the efficiency of working on the insulating centipede ladder. Once the upper platform of the insulating centipede ladder is successfully built, it can be greatly transferred by simply turning the body, so that the operator can sit on the insulating platform to complete the work, which improves efficiency and greatly reduces the physical exertion of the operator, thereby improving the satisfaction of front-line employees.

[0038] Using the improved centipede ladder for live working greatly increases the working surface of live working, and at the same time provides a better fulcrum, providing strong support for operations at a relatively far distance. Increasing the working surface can keep a larger air gap between the live working personnel and the phases, and the air gap is the main insulation between personnel and live parts, greatly reducing the risk of work.

[0039] Table 1 Average time for insulating centipede ladder operation month Insulated centipede ladder operation times Average time per session August 3 52.8 September 7 53.4 October 5 53.34 Refer to Table 1 and use the data from the improved insulated centipede ladder device for benefit analysis: The insulated centipede ladder was used for 15 operations in total, saving 89.38-52.8 minutes × 3 + 89.38-53.4 minutes × 7 + 89.38-53.18 minutes × 5 = 542.6 minutes, or about 9.04 hours, in 3 months.

[0040] Since the use of the improved insulated centipede ladder device, the overall work efficiency has been improved: 542.6 minutes ÷ 89.38 minutes × 15 = 40.5%.

[0041] Due to the improvement of the top of the insulating centipede ladder, the present invention improves the efficiency and benefit of working on the insulating centipede ladder, reduces the physical consumption of operators, and improves the satisfaction of front-line employees.

[0042] The improved insulated centipede ladder has the following advantages: 1 Reduce electricity costs. The insulated centipede ladder can be used in "all-terrain" areas, such as special areas such as fields, hillsides, and grass that traditional insulated boom trucks cannot reach, or pole towers with too many pole devices and other accessories. However, during live operations, if there are sporadic user loads on the branch side, a power supply vehicle must be dispatched to provide low-voltage terminal power supply or medium-voltage power supply on the branch side. The improved insulated centipede ladder greatly shortens the working cycle, improves work efficiency, and thus reduces the power supply time, fundamentally saving electricity costs.

[0043] 2 Environmental benefits. Most of the common power supply vehicles are still traditional diesel generators, which produce serious noise and air pollution, seriously affecting the normal rest and air environment of surrounding residents. In some special areas, live operations can only be carried out through centipede ladder operations and may require the cooperation of power supply vehicles. After the improvement, the power supply time is shortened, thereby reducing the impact of diesel generators.

Using the improved centipede ladder for live work greatly increases the working surface of live work, and at the same time provides a better point of force, providing strong support for operations at a relatively far distance. Increasing the working surface can keep a larger air gap between the live workers and the phases, and the air gap is the main insulation between the personnel and the live body, greatly reducing the risk of operation.

The structural rod 6 passes through the connecting holes of the two support rods 3, and part of the structural rod 6 passes through the outside of 2 and the support rods 3. The passed part can be used as a fulcrum for climbing, which is convenient for employees to climb.

[0080] refer to Figure 2The main bodies of the second locking device 4 and the first locking device 2 of the present invention are both quick-connect clamps, and the quick-connect clamps are provided with a movable clamp 9 and a fixed clamp 7. One end of the movable clamp 9 is hinged to one end of the fixed clamp 7, and the other end of the movable clamp 9 is connected and fixed to the other end of the fixed clamp 7 by rotating bolts. During installation, the movable clamp 9 and the fixed clamp 7 are opened so that the movable clamp 9 and the fixed clamp 7 clamp the insulating centipede ladder main body, and the movable clamp 9 and the fixed clamp 7 are connected and fixed by rotating bolts so that the second locking device 4 and the first locking device 2 are fixed to the insulating centipede ladder main body.

[0081] The second locking device 4 and the fixed clamp 7 of the first locking device 2 of the present invention are both welded to the connecting I-beam frame 8. The connecting I-beam frame 8 of the first locking device 2 is provided with a platform fixing seat 11 connected and fixed to the operating platform plate 1. The operating platform plate 1 and the platform fixing seat 11 are fixedly connected by screws. The connecting I-beam frame 8 of the first locking device 2 is provided with a rotating ear plate 10 for hingedly connecting to the other end of the support rod 3.

[0082] refer to Figure 3 The rotating bolt of the present invention includes a locking column 13, a locking bolt 14 and a locking nut 15. The locking column 13 is rotatably connected to the fixed hoop 7. The locking bolt 14 is vertically welded to the locking column 13. The locking nut 15 is threadedly connected to the locking bolt 14. The other end of the movable hoop 9 is provided with a locking wing plate 17 with a bolt slot 18. The bolt slot 18 is used to clamp the locking bolt 14. During installation, tighten the locking nut 15 to fasten the locking wing plate 17 to the fixed hoop 7, so as to fix the movable hoop 9 and the fixed hoop 7. During removal, unscrew the locking nut 15, rotate and open the locking bolt 14, so that the locking bolt 14 is separated from the bolt slot 18, thereby separating the movable hoop 9 from one end of the fixed hoop 7, and realizing quick disassembly and fixation.

[0083] In order to facilitate disassembly and assembly, the present invention has a handle 16 on the outer side of the locking nut 15 for conveniently tightening or loosening the locking nut 15 .

[0084] Since live line operations are required, the operating platform board 1 should meet the requirements of increasing the area while meeting the insulation performance requirements, ensuring the performance of increasing the indexable angle within a limited space. The operating platform board 1 is designed as an integrated insulation panel of 0.6m×0.21m, using an integrated carbon fiber winding Class III composite material cutting process, which reduces the weight while ensuring the insulation strength to meet the requirements of increasing the area.

[0085] In order to provide a fulcrum for personnel on the operating platform board 1 and prevent personnel from falling, the present invention provides a rod-shaped guardrail 5 on the operating platform board 1. The guardrail 5 is specifically arranged at one end where the operating platform board 1 is connected to the support rod 3.

[0086] The present invention sets the ratio of the length of the operating platform plate 1 to the length of the support rod 3 so that the ratio ranges from 1 / 2 to The purpose is to make the angle between the operating platform board 1 and the support rod 3 when fixed to the insulating centipede ladder body be between 45° and 60°, thereby ensuring the supporting strength of the support rod 3 and preventing the support rod 3 from being too long and inconvenient to be folded and stored after disassembly.

[0087] The inner side walls of the movable clamp 9 and the fixed clamp 7 of the present invention are fixed with an insulating protective pad 12 by screws. The surface of the insulating protective pad 12 is rough and can provide sufficient friction.

[0088] The invention improves the top of the insulating centipede ladder by installing a quick-connect platform on the top of the insulating centipede ladder, thereby improving the efficiency of working on the insulating centipede ladder. Once the upper platform of the insulating centipede ladder is successfully built, it can be greatly transferred by simply turning the body, so that the operator can sit on the insulating platform to complete the work, which improves efficiency and greatly reduces the physical exertion of the operator, thereby improving the satisfaction of front-line employees.

[0089] Using the improved centipede ladder for live working greatly increases the working surface of live working, and at the same time provides a better fulcrum, providing strong support for operations at a relatively far distance. Increasing the working surface can keep a larger air gap between the live working personnel and the phases, and the air gap is the main insulation between personnel and live parts, greatly reducing the risk of work.

[0090] Table 1 Average time for insulating centipede ladder operation Refer to Table 1 and use the data from the improved insulated centipede ladder device for benefit analysis: The insulated centipede ladder was used for 15 operations in total, saving 89.38-52.8 minutes × 3 + 89.38-53.4 minutes × 7 + 89.38-53.18 minutes × 5 = 542.6 minutes, or about 9.04 hours, in 3 months.

[0091] Since the use of the improved insulated centipede ladder device, the overall work efficiency has been improved: 542.6 minutes ÷ 89.38 minutes × 15 = 40.5%.

[0092] Due to the improvement of the top of the insulating centipede ladder, the present invention improves the efficiency and benefit of working on the insulating centipede ladder, reduces the physical consumption of operators, and improves the satisfaction of front-line employees.

[0093] The improved insulated centipede ladder has the following advantages: 1 Reduce electricity costs. The insulated centipede ladder can be used in "all-terrain" areas, such as special areas such as fields, hillsides, and grass that traditional insulated boom trucks cannot reach, or pole towers with too many pole devices and other accessories. However, during live operations, if there are sporadic user loads on the branch side, a power supply vehicle must be dispatched to provide low-voltage terminal power supply or medium-voltage power supply on the branch side. The improved insulated centipede ladder greatly shortens the working cycle, improves work efficiency, and thus reduces the power supply time, fundamentally saving electricity costs.

[0094] 2 Environmental benefits. Most of the common power supply vehicles are still traditional diesel generators, which produce serious noise and air pollution, seriously affecting the normal rest and air environment of surrounding residents. In some special areas, live operations can only be carried out through centipede ladder operations and may require the cooperation of power supply vehicles. After the improvement, the power supply time is shortened, thereby reducing the impact of diesel generators.

[0095] 3 Reduce the risk of operation. Using the improved centipede ladder for live work greatly increases the working surface of live work, and at the same time provides a better point of force, providing strong support for operations at a relatively far distance. Increasing the working surface can keep a larger air gap between the live workers and the phases, and the air gap is the main insulation between the personnel and the live body, greatly reducing the risk of operation.
