Description

Technical Field

[0001] This invention relates to the field of high-voltage circuit maintenance equipment technology, specifically an auxiliary trolley for high-voltage power supply line maintenance. Background Technology

[0002] During construction, workers need to drag pulleys along the cable. When the cable needs to be moved uphill, it takes a lot of physical strength to drag the pulleys, which can affect the progress of the work. As the workers' physical strength is depleted, their personal safety will also be affected.

[0003] In addition, when carrying out power transmission line maintenance, since line maintenance is a high-altitude operation, the construction workers walk on the high-voltage cables, which places extremely high demands on the psychological quality and construction experience of the construction workers. If the cable is too long, the construction workers will spend a lot of time walking on the cable to carry out maintenance. The cable will sway violently while walking, which will put a great burden on the physical strength and energy of the construction workers. Summary of the Invention

[0012] The present invention has the following beneficial effects: (1) This invention addresses the problems of slow movement and swaying at heights in auxiliary trolleys used for circuit maintenance. The device incorporates a roller mechanism and a mechanical mechanism. The overall weight of the trolley creates a downward force on roller one, which, through a spring-loaded sliding column, creates an upward force on base one and roller two, squeezing the cable. The three wheels tightly press the cable into the grooves of the rollers, greatly increasing stability. Roller mechanisms are located on both sides. This design enhances the stability and safety of the trolley when handling cables at heights. The control lever of the roller mechanism is rotatably connected to connecting rod two, and the fulcrum on bracket two controls the movement. Roller two is fixedly connected to the roller shaft. A cross groove is provided at the connection point between the roller shaft and the cross connecting rod for easy connection and separation. Connecting rod two rotatably connects to the cross connecting rod. When the control lever is moved, the cross connecting rod separates from the cross groove, thus losing the force provided by the roller shaft. When the trolley moves downwards from the height of the cable… When in motion, roller one rotates clockwise, and roller two rotates counterclockwise. The other end of connecting rod two is rotatably connected to gear six and a staggered gear five. When the cross groove coincides with the cross connecting rod, the other gears connected to connecting rod two are disconnected. The force during downhill movement drives the cross connecting rod to rotate counterclockwise. Then, gear one and gear two are meshed together, causing gear two to rotate clockwise. Gear two and gear three are meshed together, causing gear three to rotate counterclockwise. Gear three is fixedly connected to shaft four. When gear three rotates counterclockwise, it drives shaft four to rotate. Shaft four is fixedly connected to the slot. When the slot rotates, it drives the vortex spring to rotate counterclockwise. The vortex spring's energy storage process not only accumulates forward power for the next stage but also slows down the downhill speed, achieving a gradual deceleration effect. This reduces the need for manual braking and foot pedaling, indirectly improving the stability of the equipment during operation.

[0013] (2) This invention utilizes the characteristic of the above-mentioned vortex spring to accumulate mechanical power during operation and uses a control lever to control it. When the vortex spring is accumulating power downhill, when the vortex spring rotates and accumulates power to the limit, the tail block will disengage from the first slot due to the limit force, releasing some of the accumulated power. After releasing some of the accumulated power, it will be locked by the next slot, repeating the process to avoid excessive power accumulation that could cause the vortex spring to break, until the power of the vortex spring is completely released. In addition, when the trolley moves downhill on the cable, the vortex spring on the trolley can effectively play a role in energy storage and deceleration. However, when the speed is too fast, it can be decelerated by using a brake lever. The brake lever is connected to the brake caliper through the brake cable and works with the deceleration groove on the shaft to decelerate, preventing the speed from being too fast when reaching the next power tower downhill.

[0014] (3) In this invention, the spiral spring in the above-mentioned mechanical mechanism is used. One end of the connecting rod 2 is rotatably connected to gear 6 and gear 5. Moving the connecting rod 2 to the right by one gear will disconnect the cross connecting rod from the roller shaft. At the same time, gear 6, which is rotatably connected to the connecting rod 2, will mesh with gear 7 and gear 4. Because the connection of the cross connecting rod is disconnected, the spiral spring no longer stores energy and instead releases clockwise kinetic energy. This energy is then used to drive gear 4 to rotate clockwise through shaft 4. Gear 4 drives gear 6, which has just been meshed, to rotate counterclockwise. The counterclockwise rotation of gear 6 drives gear 7 to rotate clockwise. Gear 7 is fixedly connected to shaft 2 and drives shaft 2 to rotate clockwise. Shaft 2 and roller 1 are fixedly connected. The spiral spring no longer stores energy but releases clockwise kinetic energy. Through the connecting rod, shaft 2 drives roller 1 to rotate clockwise, thus providing power for the trolley to move forward. When connecting rod 2 moves one position to the right, the mechanical structure causes the spiral spring to change from storing energy to releasing energy. Because of the force provided by the spiral spring, workers can use the foot pedal structure more effortlessly when going uphill.

[0015] (4) This invention utilizes the aforementioned mechanical mechanism. When the control lever is moved to the far left, the roller shaft and the cross connecting rod are fixedly connected, causing gears six and five on the rear end of connecting rod two to move to the left. Gear six is ​​not connected to any gear, but gear five is meshed with gears seven and four. Through the locking wheel between the gears, and the roller mechanism, roller one moves forward with a clockwise force and roller two moves forward with a counterclockwise force, causing them to conflict and stop rotating, thus stabilizing the roller on the cable. When the control lever is to the far right, all the gears on connecting rod two are shifted to the right, and the roller shaft separates from the cross connecting rod. Gears six and five are disconnected, preventing the force from the foot pedal driving the roller mechanism from reaching the vortex spring and rendering it useless. Additionally, due to the foot pedal mechanism, the power provided by the foot pedal during high-altitude work inevitably causes the trolley to sway from side to side. A retractable box mounted on support one controls the counterweight hanging below support one. When the foot pedal sways, the retractable box lowers the counterweight, acting as a balancer. In strong winds, the retractable box raises the counterweight to the bottom of support one to balance the trolley, securing the cable within the spring sliding column of the roller mechanism.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1-7 This invention relates to an auxiliary trolley for the maintenance of high-voltage power supply lines, comprising an integral support frame 11, which includes a crossbar support 12 fixedly connected to the inner wall of the support frame 11, a seat 13 fixedly connected to the outer wall of the crossbar support 12, a support frame 31 fixedly connected to the outer wall of the support frame 11, a safety hole 38 formed on the outer wall of the support frame 31, a support frame 61 fixedly connected to the end of the support frame 11 away from the support frame 31, a safety hole 68 fixedly connected to the outer wall of the support frame 31, a foot pedal mechanism 2 fixedly connected to a foot pedal housing 21 on the outer wall of the support frame 11, a drive wheel 22 rotatably connected to the inner wall of the foot pedal housing 21, a foot pedal 23 fixedly connected to the outer wall of the drive wheel 22, and a roller mechanism 3 fixedly connected to the support frame 31 on the outer wall of the support frame 11. Roller 32 is rotatably connected to the inner wall of bracket 31, and an adjusting base 33 is fixedly connected to the outer wall of bracket 31. Two spring sliding columns 34 are connected through the upper part of the adjusting base 33, and base 35 is fixedly connected to the upper part of the two spring sliding columns 34. Roller shaft 37 is rotatably connected to the inner wall of the two bases 35, and roller 36 is fixedly connected to the outer wall of the roller shaft 37. The overall weight of the trolley causes the roller 32 to exert a downward force, which is then transferred to the base 35 and roller 36 through the spring sliding columns 34 to exert an upward force to squeeze the cable. The three wheels tightly squeeze the cable into the middle of the roller groove, greatly increasing its stability. Roller mechanisms 3 are set on both sides. The design of this device improves the stability and safety of the trolley for high-altitude cables.

[0021] The balancing mechanism 1 also includes a retractable box 14 fixed to the outer wall of the crossbar support 12. A take-up shaft 15 is rotatably connected to the inner wall of the retractable box 14. A rocker arm 16 is fixedly connected to the outer wall of the take-up shaft 15.

A retractable rod 17 is fixedly connected to the bottom of the retractable box 14. A counterweight 19 is fixedly connected to the lower part of the retractable rod 17. The equipment is equipped with a balancing mechanism 1, a foot pedal mechanism 2, a roller mechanism 3, and a mechanical mechanism 4. Due to the foot pedal mechanism 2, the power provided by the foot pedal when the worker is working at height will inevitably cause the pulley to sway from side to side. The counterweight 19 hanging below the support 11 is controlled by the retractable box 14 installed on the support 11. When the worker steps on the foot pedal, the counterweight 19 is lowered by the retractable box 14, which acts as a balancing pulley. In strong winds, the counterweight 19 is raised to the bottom of the support 11 to balance the pulley.

[0022] Example 2, please refer to Figures 5-11 This invention is an auxiliary trolley for the maintenance of high-voltage power supply lines. Based on Embodiment 1, the foot pedal mechanism 2 further includes a transmission belt 24 rotatably connected to the outer wall of the power wheel 22.

An adjusting wheel 25 is rotatably connected to the inner wall of the foot pedal housing 21. The outer wall of the adjusting wheel 25 is rotatably connected to the inner wall of the transmission belt 24. A shaft 27 is rotatably connected to the inner wall of the second bracket 31.

[0023] The mechanical mechanism 4 also includes a roller shaft 37 with a cross groove 411 at one end close to the support 2 31. A cross connecting rod 42 is fixedly connected to the inner wall of the cross groove 411. A gear 1 43 is fixedly connected to the outer wall of the cross connecting rod 42. A shaft 3 41 is rotatably connected to the outer wall of the support 2 31. A gear 2 44 is fixedly connected to the outer wall of the shaft 3 41. The gear 2 44 and the gear 1 43 are meshed. A shaft 45 is rotatably connected to the outer wall of the support 2 31. A gear 3 46 and a gear 47 are fixedly connected to the outer wall of the shaft 45. A shaft 5 48 is rotatably connected to the outer wall of the support 2 31. A gear 5 49 is slidably connected to the outer wall of the shaft 5 48. A gear 6 410 is slidably connected to the outer wall of the shaft 5 48. The gear 6 410 and the gear 5 49 are fixedly connected.

[0024] A connecting rod 415 is rotatably connected to the end of gear 6 410 away from gear 5 49. A cross connecting rod 42 is rotatably connected to the end of connecting rod 2 415 away from gear 6 410. A sliding column 412 is fixedly connected to the outer wall of bracket 2 31. The bottom of connecting rod 2 415 is slidably connected to sliding column 412. An operating lever 416 is rotatably connected to the outer wall of connecting rod 2 415. The middle part of the operating lever 416 is rotatably connected to bracket 2 31. A gear 7 413 is fixedly connected to the end of shaft 210 away from roller 1 32. A spring housing 51 is fixedly connected to the outer wall of bracket 2 31. A slot 52 is rotatably connected to the inner wall of the spring housing 51. The slot 52 is fixedly connected to shaft 45. A spiral spring 53 is rotatably fixed to the inner wall of the spring housing 51. A tail block 54 is provided at the tail end of the spiral spring 53. A slot 55 is opened on the inner wall of the spring housing 51. The tail block 54 is fitted to the slot 55.

[0025] A roller 62 is rotatably connected to the upper end of bracket 361. A shaft 63 is fixedly connected to the inner wall of roller 362. A brake caliper 64 is rotatably connected to the outer wall of roller 362 and shaft 63. Brake caliper 64 is fixedly connected to bracket 361. A brake cable 65 is fixedly connected to the outer wall of brake caliper 64. It is controlled by a lever 416, which is rotatably connected to a connecting rod 415. The lever 416 passes through a fulcrum on bracket 231, allowing for easy prying control. Roller 236 is fixedly connected to roller shaft 37. A cross groove 411 is provided at the connection point of the cross connecting rod 42 to facilitate connection and separation. Connecting rod two 415 is rotatably connected to the cross connecting rod 42. When the control lever 416 is moved, the cross connecting rod 42 separates from the cross groove 411, thus losing the force provided by the roller shaft 37. When the trolley moves downwards from the cable height, roller one 32 rotates clockwise, and roller two 36 rotates counterclockwise. The other end of connecting rod two 415 is rotatably connected to gear six 410 and a staggered gear five 49. When the cross groove 411 coincides with the cross connecting rod 42, connecting rod two 415... All other gears connected to 5 are disconnected. The force of the downhill movement drives the cross connecting rod 42 to rotate counterclockwise. Then, through the fixed connection, gear 1 43 meshes with gear 2 44, causing gear 2 44 to rotate clockwise. Gear 2 44 meshes with gear 3 46, causing gear 3 46 to rotate counterclockwise. Gear 3 46 is fixedly connected to shaft 45. When gear 3 46 rotates counterclockwise, it drives shaft 45 to rotate. Shaft 45 is fixedly connected to slot 52. When slot 52 rotates, it drives the spiral spring 53 to rotate counterclockwise. As the needle rotates, when the spiral spring 53 reaches its limit, the tail block 54 will disengage from the slot 55, releasing some force. This process is repeated until the force of the spiral spring 53 is completely released. When the trolley moves down the cable, the spiral spring 53 on the trolley can effectively store energy and slow down the cable. However, when the speed is too high, it can be slowed down by using the brake lever 66. The brake lever 66 is connected to the brake caliper 64 through the brake cable 65, and works with the deceleration groove 67 on the shaft 63 to slow down the cable and prevent the speed from being too high when reaching the next power tower on the downhill slope.

[0026] A brake lever 66 is fixedly connected to the upper end of bracket 11. The brake lever 66 is fixedly connected to the brake cable 65. A reduction groove 67 is provided at the engagement point of the brake caliper 64 on shaft 63. Gear 2 44 and gear 3 46 are meshed. One end of connecting rod 2 415 is rotatably connected to gear 6 410 and gear 5 49. Moving connecting rod 2 415 one gear to the right will disengage the cross connecting rod 42 from the roller shaft 37, and simultaneously rotate the gear connected to connecting rod 2 415. Gear 410 engages with gears 413 and 47. Because the cross connecting rod 42 is disconnected, the vortex spring 53 no longer stores energy and instead releases clockwise kinetic energy. This energy is transmitted through shaft 45 to drive gear 47 to rotate clockwise. Gear 47 then drives gear 410, which was just engaged, to rotate counterclockwise. The counterclockwise rotation of gear 410 drives gear 7 413 to rotate clockwise. Since gear 7 413 is fixedly connected to shaft 210, it drives shaft 210 to rotate clockwise. Shaft 210 is fixedly connected to roller 32, thus providing forward force. Through the setting of mechanical mechanism 4, when the control lever 416 is moved to the leftmost position, the roller shaft 37 is fixedly connected to the cross connecting rod 42, and the gear 5 49 is meshed with the gear 7 413 and the gear 4 47. Through the direct locking of the gears, plus the setting of roller mechanism 3, it is stably stopped on the cable. When the control lever 416 is to the rightmost position, all the gears on the connecting rod 2 415 are dislocated, and it is not used or has any function.

[0027] A specific application of this embodiment is as follows: The balancing mechanism 1, foot pedal mechanism 2, roller mechanism 3, and mechanical mechanism 4 are used. Due to the foot pedal mechanism 2, the power provided by the foot pedal during high-altitude operations inevitably causes the trolley to sway from side to side. The counterweight 19 hanging below the support 11 is controlled by the retractable box 14 installed on the support 11. When the trolley sways while being stepped on, the retractable box 14 lowers the counterweight 19, thus balancing the trolley. In strong winds, the retractable box 14 raises the counterweight 19 to the bottom of the support 11 to achieve the same balancing effect. The cable is fixed within the roller mechanism 3 using a spring-loaded sliding column. The overall weight of the trolley causes a downward force on the roller 32, and the spring-loaded sliding column 34, along with the base 35 and roller 36, exerts an upward force to compress the cable. The three rollers tightly press the cable into the grooves of the rollers, greatly increasing its stability. Roller mechanisms 3 are installed on both sides. This device improves the stability and safety of the trolley for high-altitude cable operations.

[0028] Using the aforementioned mechanical mechanism 4, it is controlled by a lever 416. The lever 416 is rotatably connected to a connecting rod 415, which passes through a fulcrum on the bracket 31. This prying control is very labor-saving. Roller 36 is fixedly connected to roller shaft 37. A cross groove 411 is provided at the connection point between roller shaft 37 and cross connecting rod 42 for easy connection and separation. Connecting rod 415 rotatably connects to cross connecting rod 42. When the lever 416 is moved, cross connecting rod 42 separates from cross groove 411, thus losing the force provided by roller shaft 37. When the trolley moves downwards from the cable height, roller 32 rotates clockwise, and roller 36 rotates counterclockwise. The other end of connecting rod 415 is rotatably connected to gear 410 and a staggered gear 49. When cross groove 411 coincides with cross connecting rod 42, the other gears connected to connecting rod 415 are disconnected. The force during downhill movement drives cross connecting rod 42 to rotate counterclockwise. Gear 1 43 is meshed with gear 2 44 via a fixed connection, causing gear 2 44 to rotate clockwise. Gear 2 44 is meshed with gear 3 46, causing gear 3 46 to rotate counterclockwise. Gear 3 46 is fixedly connected to shaft 45. When gear 3 46 rotates counterclockwise, it drives shaft 45 to rotate. Shaft 45 is fixedly connected to slot 52. When slot 52 rotates, it drives the vortex spring 53 to rotate counterclockwise. When the vortex spring 53 rotates to its limit, the tail block 54 will disengage from slot 1 55, releasing some force. This process is repeated until the force of the vortex spring 53 is completely released. When the trolley moves down the cable, the vortex spring 53 on the trolley can effectively store energy and slow down the cable. However, when the speed is too high, it can be slowed down by using the brake lever 66. The brake lever 66 is connected to the brake caliper 64 through the brake cable 65, and works with the deceleration groove 67 on shaft 63 to slow down the cable, preventing the speed from being too high when reaching the next power tower on the downhill slope.

[0029] One end of connecting rod 2 415 is rotatably connected to gear 6 410 and gear 5 49. Moving connecting rod 2 415 one gear to the right will disconnect cross connecting rod 42 from roller shaft 37. At the same time, gear 6 410, which is rotatably connected to connecting rod 2 415, will mesh with gear 7 413 and gear 4 47. Because the connection of cross connecting rod 42 is disconnected, the vortex spring 53 no longer stores energy and instead releases clockwise kinetic energy. This energy is then used to drive gear 4 47 to rotate clockwise through shaft 4 45. Gear 4 47 then drives gear 6 410, which was just meshed, to rotate counterclockwise. The counterclockwise rotation of gear 6 410 drives gear 7 413 to rotate clockwise. Gear 7 413 is fixedly connected to shaft 2 210, thus driving shaft 2 210 to rotate clockwise. Shaft 210 is fixedly connected to roller 32, thus providing forward force.
