Description

Technical Field

[0001] This utility model relates to the field of power plant cable transportation, and in particular to a foot-operated high-voltage cable transportation device. Background Technology

[0002] In the power generation industry, heavy-duty high-voltage cable relocation is frequently encountered. Currently, there are two main methods for high-voltage cable relocation: First, purely manual operation, where workers directly pull or carry the cable by hand or in a coordinated effort. This method is inefficient and poses safety hazards. Relying entirely on manual labor is extremely strenuous, requires multiple workers, and is highly likely to cause occupational health problems such as muscle strains. Second, using simple auxiliary tools such as rollers, crowbars, or manual hoists. While these tools provide some assistance, they cannot provide continuous and controllable moving force and are difficult to use in confined spaces such as transformer substations and switchgear. The common problems are inflexible movement, difficulty in using them in confined spaces, and even inability to place them, rendering them ineffective and ultimately requiring manual operation, failing to fundamentally solve the problem.

[0003] In addition, tools such as rollers and crowbars are mostly made of metal or hard plastic, and their surfaces lack cushioning protection. When they come into contact with the cable sheath, they cannot avoid potential damage to the cable sheath, leaving safety hazards such as leakage and short circuits. Utility Model Content

[0004] This utility model provides a foot-operated high-voltage cable transport device, which solves the problems of manual operation being extremely labor-intensive, requiring multiple people to cooperate, and easily causing muscle strain; simple auxiliary tools being inflexible in movement, difficult to use in confined spaces, or even impossible to place, and simple auxiliary tools potentially damaging the cable sheath.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a foot-operated high-voltage cable transport device, including a gearbox, a lever mechanism and a gear assembly on the gearbox, the lever mechanism including a pedaling mechanism, a transmission mechanism and an inertia wheel, the inertia wheel being connected to the gear assembly, a pulley group being provided on the top of the gearbox, the pulley group including a first side wheel, a second side wheel and multiple side wheels, the first side wheel and the second side wheel being connected to the gear assembly.

[0006] In the preferred embodiment, the gearbox has a base plate at the bottom, a pedal groove on one side, a rotating frame on one side, and a rotatably connected guide wheel on the rotating frame.

[0007] In a preferred embodiment, the pedaling mechanism includes a connecting plate, one end of which is provided with a foot pedal that extends out of the pedal groove.

[0008] In a preferred embodiment, the transmission mechanism includes a base and a connecting rod. The base is provided with a rotatably connected side rod, and a connecting plate is rotatably connected to the base. One end of the side rod is provided with a counterweight, and the connecting rod is rotatably connected to the counterweight. The side rod is connected to the connecting plate.

[0009] In a preferred embodiment, the inertia wheel includes a wheel body, a vertical shaft on the wheel body, a rotating seat at the bottom of the vertical shaft, the rotating seat being rotatably connected to a connecting rod, an inlaid key at the top of the vertical shaft, and a crank on the vertical shaft.

[0010] In a preferred embodiment, a jacking device is provided on one side of the inertia wheel. The jacking device includes a rotating top seat, which is rotatably connected to the vertical shaft. A U-shaped block is provided on one side of the rotating top seat, and a sliding frame is provided on the U-shaped block.

[0011] In the preferred embodiment, a spring is provided between the sliding frame and the bottom of the U-shaped block, and a push wheel is provided at one end of the sliding frame for rotational connection. The push wheel abuts against the crank, and the U-shaped block is connected to the gearbox.

[0012] In a preferred embodiment, the gear assembly includes a rotating shaft, an inlaid key is inlaid on the rotating shaft, a main gear is provided on the rotating shaft, meshing driven gears are provided on both sides of the main gear, and two side shafts are provided on the two driven gears respectively, and the two side shafts are respectively connected to a first side wheel and a second side wheel.

[0013] In the preferred embodiment, both the rotating shaft and the side shaft are rotatably connected to the gearbox, and a second side shaft is provided on both sides of the side shaft. The second side shaft is connected to the side wheel and is rotatably connected to the gearbox.

[0014] The beneficial effects of this utility model are as follows: When transporting high-voltage cables, the cable is manually inserted between the first and second side wheels, with the cable on the gearbox side abutting against the guide wheel. Reciprocating foot pedal movement causes the pedal mechanism to reciprocate, rotating one end of the transmission mechanism, which in turn rotates the inertia wheel, the insert key, and the main gear of the gear assembly. This, in turn, causes the first and second side wheels to rotate, clamping and transporting the cable. Friction drives the cable forward in a straight line, requiring only manual guidance from the operator. This avoids the extreme labor intensity of manual pulling, which requires multiple people and is highly prone to muscle strain. The pulley system is equipped with rubber anti-slip pads, preventing potential damage to the cable sheath from tools such as rollers and crowbars, thus avoiding potential safety hazards such as leakage and short circuits.

[0015] The overall structure transforms multi-person collaboration into single-person or two-person operation: through a dual force-amplifying mechanism of pedaling, transmission, and gear assembly, the power of the human leg is amplified, enabling a single person's foot pedal force to generate the traction force required to drive a cable weighing hundreds of kilograms, completely eliminating the reliance on multiple human laborers and improving work efficiency.

[0016] With its compact and lightweight design, it can easily fit into confined spaces where traditional equipment cannot be used, such as transformer substations, switch cabinets, and cable trenches, greatly expanding its application scenarios.

[0017] The overall structure provides precise protection during dragging: it adopts a V-groove rubber anti-slip pulley system, which provides sufficient friction to prevent slippage, and its elastic material and reasonable layout can evenly distribute the clamping force, effectively avoiding permanent damage such as scratches and indentations to the cable sheath caused by traditional steel wire ropes or hard dragging, thus ensuring the long-term safe operation of the cable.

Detailed Implementation

[0019] Example 1: like Figure 1-6The foot-operated high-voltage cable transport device includes a gearbox 2, which is equipped with a lever mechanism and a gear assembly 3. The lever mechanism includes a pedaling mechanism 4, a transmission mechanism 5, and an inertia wheel 6. The inertia wheel 6 is connected to the gear assembly 3. A pulley system is provided on the top of the gearbox 2, which includes a first side wheel 10, a second side wheel 11, and multiple side wheels 12. The first side wheel 10 and the second side wheel 11 are connected to the gear assembly 3. With this structure, when it is necessary to transport high-voltage cables, the cable is manually inserted between the first side wheel 10 and the second side wheel 11, and the cable on one side of the gearbox 2 rests against the guide wheel 9. The foot pedal 401 is reciprocated, causing the pedaling mechanism 4 to reciprocate, which in turn rotates one end of the transmission mechanism 5, causing the inertia wheel 6 to rotate, the insert key 604 to rotate, the main gear 302 of the gear assembly 3 to rotate, and the first side wheel 10 and the second side wheel 11 to rotate. The first side wheel 10 and the second side wheel 11 then clamp and transport the cable. The cable is driven forward in a straight line by friction, requiring only manual guidance from the operator. This avoids the extreme labor intensity and need for multiple people to work together, which can easily lead to muscle strain. The pulley system is equipped with rubber anti-slip pads, and also prevents potential damage to the cable sheath from tools such as rollers and crowbars, thus avoiding potential safety hazards such as leakage and short circuits.

[0020] The overall structure transforms multi-person collaboration into single-person or two-person operation: through the dual force-amplifying mechanism of pedaling mechanism 4, transmission mechanism 5 and gear assembly 3, the power of the human leg is amplified, so that the pedaling force of a single person can generate the traction force required to drive a cable weighing hundreds of kilograms, completely solving the dependence on multiple people and improving work efficiency.

[0021] With its compact and lightweight design, it can easily fit into confined spaces where traditional equipment cannot be used, such as transformer substations, switch cabinets, and cable trenches, greatly expanding its application scenarios.

[0022] The overall structure provides precise protection during dragging: it adopts a V-groove rubber anti-slip pulley system, which provides sufficient friction to prevent slippage, and its elastic material and reasonable layout can evenly distribute the clamping force, effectively avoiding permanent damage such as scratches and indentations to the cable sheath caused by traditional steel wire ropes or hard dragging, thus ensuring the long-term safe operation of the cable.

[0023] In the preferred embodiment, the gearbox 2 has a base plate 1 at the bottom, a pedal groove on one side, a rotating frame 8 on one side, and a rotatably connected guide wheel 9 on the rotating frame 8.

[0024] In a preferred embodiment, the pedal mechanism 4 includes a connecting plate 402, one end of which is provided with a foot pedal 401 extending out of a pedal groove. With this structure, by driving the pedal mechanism 4, the traction force required to drive a cable weighing hundreds of kilograms can be generated by a single person's foot pedal force, completely eliminating the reliance on multiple human laborers and improving work efficiency.

[0025] In a preferred embodiment, the transmission mechanism 5 includes a base 501 and a connecting rod 504. A side rod 502 is rotatably connected to the base 501. A connecting plate 402 is rotatably connected to the base 501. A counterweight 503 is provided at one end of the side rod 502. The connecting rod 504 is rotatably connected to the counterweight 503. The side rod 502 is connected to the connecting plate 402. With this structure, when the pedaling mechanism 4 reciprocates up and down, one end of the connecting rod 504 rotates, causing the inertia wheel 6 to rotate, which in turn causes the main gear 302 to rotate. The counterweight 503 serves as a counterweight.

[0026] In a preferred embodiment, the inertia wheel 6 includes a wheel body 601, a vertical shaft 603 mounted on the wheel body 601, a rotating seat 602 at the bottom of the vertical shaft 603, the rotating seat 602 being rotatably connected to the connecting rod 504, an inlaid key 604 at the top of the vertical shaft 603, and a crank 605 mounted on the vertical shaft 603. With this structure, when the pedaling mechanism 4 reciprocates up and down, the wheel body 601 rotates, causing the vertical shaft 603 to rotate, which in turn causes the crank 605 to rotate.

[0027] In a preferred embodiment, a pushing device 7 is provided on one side of the inertia wheel 6. The pushing device 7 includes a rotating top seat 701, which is rotatably connected to the vertical shaft 603. A U-shaped block 702 is provided on one side of the rotating top seat 701, and a sliding frame 703 is provided on the U-shaped block 702. With this structure, the lever mechanism has a dead point, which can slide past the dead point under the action of inertia. The crank 605 and the pushing device 7 cooperate, and when the dead point position is reached, the spring 704 pushes the sliding frame 703 to slide relative to the U-shaped block 702, so that the pushing wheel 705 pushes the crank 605, so that the inertia wheel 6 passes the dead point under the action of the spring force.

[0028] In a preferred embodiment, a spring 704 is provided between the bottom of the sliding frame 703 and the U-shaped block 702, and a pusher 705 is provided at one end of the sliding frame 703 for rotational connection. The pusher 705 abuts against the crank 605, and the U-shaped block 702 is connected to the gearbox 2.

[0029] In a preferred embodiment, the gear assembly 3 includes a rotating shaft 301, with a key 604 embedded in the shaft 301. A main gear 302 is mounted on the shaft 301, and meshing driven gears 303 are located on both sides of the main gear 302. Each driven gear 303 has a side shaft 304, which is connected to a first side wheel 10 and a second side wheel 11, respectively. This structure provides the first level of effort-saving leverage. The gears within the gearbox 3 have a large transmission ratio, with the transmission ratio between the main gear 302 and the driven gears 303 being 10:1 to 20:1. This drives the vertical shaft 603 with the inertia wheel 6, achieving the second level of force amplification and smooth power output. The rotational torque of the key 604 is transmitted to the pulley system, driving the cable to move linearly through friction.

[0030] In the preferred embodiment, both the rotating shaft 301 and the side shaft 304 are rotatably connected to the gearbox 2. A second side shaft is provided on both sides of the side shaft 304, and the second side shaft is connected to the side wheel 12, which is also rotatably connected to the gearbox 2. With this structure, the first side wheel 10, guide wheel 9, second side wheel 11, and side wheel 12 utilize V-groove rubber anti-slip components, providing sufficient friction to prevent slippage. Their elastic material and reasonable layout also evenly distribute the clamping force, effectively avoiding permanent damage such as scratches and indentations to the cable sheath caused by traditional steel wire ropes or hard dragging, thus ensuring the long-term safe operation of the cable.
