The present invention relates to the field of electronic power maintenance technology. The electronic power equipment maintenance auxiliary device can adjust the standing area of ​​the maintenance personnel on the lifting platform, which not only increases the activity space of the maintenance personnel, but also facilitates the maintenance personnel to better perform maintenance work, effectively improves the safety of the maintenance personnel's high-altitude maintenance, meets the simultaneous use of multiple maintenance personnel, and greatly improves the function of the electronic power equipment maintenance equipment.

[0004] However, in the above-mentioned electronic power equipment maintenance auxiliary device, during the maintenance of power equipment, it is not possible to conveniently transport tools from the ground to a high place for maintenance personnel to use, which means that maintenance personnel need to frequently go up and down the high working platform to obtain tools, which increases the time cost and physical exertion of work. For example, when repairing large power tower equipment, if there is a lack of maintenance tools, maintenance personnel need to descend the platform to get them, and then ascend the platform to continue working, which is not only inefficient, but also increases the fatigue of maintenance personnel, which may affect the quality and safety of maintenance;

[0005] At the same time, when pushing up the work platform, the bottom support cannot be stabilized according to the terrain to avoid tilting. Summary of the invention

[0006] The purpose of the present invention is to provide an auxiliary device for the maintenance of electric equipment to solve the problem raised in the above-mentioned background technology that during the maintenance of electric equipment, tools cannot be conveniently transported from the ground to a high place for maintenance personnel to take and use. This means that maintenance personnel need to frequently go up and down high working platforms to obtain tools, which increases the time cost and physical exertion of work. At the same time, in the process of pushing up the working platform, the bottom cannot be supported steadily according to the terrain to avoid the problem of tilting and falling.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An auxiliary device for maintenance of electric power equipment, comprising: a chassis, rollers are rotatably mounted on both sides of the chassis, and support mechanisms are rotatably mounted on both ends of the lower surface of the chassis, so that the support mechanisms can support the chassis top support;

[0009] A lifting mechanism is rotatably mounted on the upper surface of the chassis, a working platform is fixedly mounted on the upper surface of the lifting mechanism, a ladder is fixedly mounted on one end of the working platform, and the bottom of the ladder is supported on the upper surface of the chassis so that workers can climb into the working platform and be lifted up by the lifting mechanism;

[0010] Among them, one end of the work platform is connected and installed with an equipment conveying mechanism, which can extend to the upper surface of the chassis and can hang the required equipment to be reeled up and lifted up by the equipment conveying mechanism for the staff to take and use.

[0011] Preferably, the lifting mechanism includes a frame plate, and docking plates are fixedly installed on the four corners of the upper and lower surfaces of the frame plate, and support rods are rotatably installed in the docking plate. The four groups of support rods on the lower surface of the frame plate are rotatably installed on the upper surface of the chassis, and the four groups of support rods on the upper surface of the frame plate are rotatably connected to the four groups of support rods on the lower surface of another group of frame plates, and connecting rods are rotatably installed between the four groups of support rods on the left and right sides.

[0012] Preferably, transmission columns are fixedly installed on the lower surfaces of the two groups of connecting rods, and the two groups of transmission columns are respectively threadedly installed on the outer surfaces of the positive threaded rod and the reverse threaded rod, and the positive threaded rod and the reverse threaded rod are fixedly connected together, and the positive threaded rod and the reverse threaded rod are fixedly installed on one end of the output shaft of the first motor, the first motor slides in the first guide cylinder, and the second guide cylinder is slidably installed in the first guide cylinder, and the first guide cylinder is fixedly installed on the upper surface of the chassis, so that when the positive threaded rod and the reverse threaded rod are driven to rotate by the first motor, they can threadably drive the two groups of connecting rods to push outward, and then the support rods rotatably installed between the frame plates can be pushed to the outer ends and expanded to a vertical shape, thereby increasing the spacing between the two groups of frame plates, and a working platform is fixedly installed on the upper surface of the topmost frame plate, so as to perform a jacking operation on the working platform.

[0013] Preferably, when the support rods rotatably installed between the two groups of frame plates are pushed outward and expanded to a vertical state, a square frame can be formed between the two groups of frame plates, and the expanded square frame can increase the bearing capacity while improving the stable supporting force.

[0014] Preferably, when the frame plate is pushed and unfolded, the positive threaded rod and the negative threaded rod are also driven to rise a certain distance, thereby driving the first motor to slide vertically upward in the first guide cylinder.

[0015] Preferably, the first motor between the two groups of frame plates on the upper layer slides in the second guide cylinder, and when the two groups of frame plates on the upper layer are pushed and unfolded, the first motor can push the second guide cylinder to slide upward in the first guide cylinder.

[0016] Preferably, the supporting mechanism includes a docking rod, which is fixedly mounted on both sides of the lower surface of the chassis, a first connecting arm is rotatably mounted on one end of the docking rod, a second connecting arm is rotatably mounted on the lower surface of the first connecting arm, a universal ball is fixedly mounted on the other end of the second connecting arm, and a support plate is rotatably mounted on the outer surface of the universal ball.

[0017] Preferably, a connecting plate is fixedly installed at one end of the docking rod, and a first hydraulic rod is rotatably installed in the connecting plate. The piston rod of the first hydraulic rod is rotatably installed at one end of the first connecting arm, so that the first hydraulic rod can push the first connecting arm to flip and unfold. A second hydraulic rod is rotatably installed on the lower surface of the first connecting arm, and the piston rod of the second hydraulic rod is rotatably installed at one end of the second connecting arm, so that the second hydraulic rod can push the second connecting arm to flip and unfold. The flipping and unfolding of the first and second connecting arms can increase the supporting area of ​​the chassis, and the height distance supported by the chassis can be regulated by the inclination angle of the second connecting arm when it is pushed open, and the pushing of the second connecting arm can adjust the supporting position of the support plate.

[0018] Preferably, the equipment conveying mechanism includes an installation frame, which is fixedly mounted on one end of the working platform. A second motor is fixedly mounted on one end of the installation frame. The output shaft of the second motor passes through the installation frame and a winch is fixedly mounted on the end so that the winch is rotatably mounted on the installation frame. The head of the rope that is wound up on the outer surface of the winch is fixedly connected with a spring buckle.

[0019] Preferably, the rope of the winch passes through the upper surface of the placement box to the lower surface. The placement box is fixedly installed at one end of the working platform and is located directly below the installation frame. There is a rotating closing cover in the placement box, and the closing cover is flipped upward, so that the closing cover can be pushed open when pulled by a spring buckle, and after the spring buckle is pulled into the placement box by the rope, the closing cover can naturally fall down to close the bottom of the placement box, so that the instrument hung by the spring buckle can be placed in the placement box.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the design of chassis, working platform, supporting mechanism, lifting mechanism and equipment conveying mechanism, when in use, the chassis can be moved to the area that needs maintenance by rollers, and then the supporting mechanism is started to support the chassis according to the ground, and the chassis can be tilted and adjusted in height according to the terrain to ensure the level of the chassis. This adaptive adjustment capability can ensure that the working platform is in a horizontal and stable state for maintenance work. For example, near the outdoor power tower base, there may be slopes or potholes on the ground. The supporting mechanism can be adjusted according to these terrains, which improves the applicability and stability of the entire device. After that, the staff can enter the working platform through the ladder and start the lifting mechanism to lift the working platform to the height required for maintenance for maintenance operations. In the process of maintenance, if any maintenance tools are forgotten, the staff below can hang the maintenance tools on the outer surface of the tool conveying mechanism and be lifted into the working platform. This function greatly improves the efficiency of maintenance work, avoids the staff from frequently going up and down the working platform due to lack of tools, and ensures the continuity of maintenance work. In some complex maintenance tasks, timely obtaining the required tools can shorten the maintenance time, reduce the power outage time of equipment, and improve the reliability of power supply.

[0022] 2. Through the design of the frame plate, the support rod, the positive thread rod, the reverse thread rod, the first motor, the first guide cylinder and the second guide cylinder, when the work platform is supported, the three first motors can be started to drive the positive thread rod and the reverse thread rod to drive the two groups of connecting rods to push outward, so that the support rods rotatably installed between the frame plates can be pushed outward and expanded vertically, so that a square frame can be formed between every two groups of frame plates. The expanded square frame structure has better stability in mechanics than the scissor lift, and can increase the bearing capacity of the work platform. During the maintenance of power equipment, the work platform needs to bear the weight of maintenance personnel, maintenance tools and equipment, etc. This stable support structure can ensure The working platform is ensured not to be deformed or collapsed when bearing a heavy weight, and the positive threaded rod and the reverse threaded rod are also driven to rise a certain distance in the process of the frame plate being pushed and unfolded, thereby driving the first motor to slide vertically upward in the first guide cylinder, and the first motor between the two sets of frame plates on the upper layer slides in the second guide cylinder, so that the first motor can push the second guide cylinder to slide upward in the first guide cylinder in the process of being pushed upward. This linkage design enables the working platform to automatically adapt to changes in height during the jacking process, without the need for additional complex operations to adjust the position of the first motor. This feature enables the working platform to maintain a stable support structure and normal operating state under different working height requirements.

[0023] 3. Through the design of the first connecting arm, the second connecting arm, the first hydraulic rod, the second hydraulic rod, the universal ball and the support plate, when supporting the chassis, the first hydraulic rod can be activated to push the first connecting arm to a rotating and unfolded position according to the terrain area, and because the support plate at one end of the second connecting arm is rotatably installed at one end of the first connecting arm, the support point position of the support plate can be adjusted according to the flip-open angle position of the first connecting arm, so that suitable support points can be found in terrain areas of different shapes and sizes. For example, when supporting equipment in irregular mountainous areas or narrow urban building gaps, the support points can be flexibly adjusted according to the actual terrain to improve the adaptability of the chassis support, and then the second hydraulic rod can be activated to tilt and unfold the second connecting arm and drive The support plate is supported on the ground, and the support plate is rotated on the outer surface of the universal ball installed at one end of the second connecting arm, so that the support plate can be accurately fitted to the support point through the rotation of the universal ball, and the height distance supported by the chassis can be adjusted by the inclination angle of the second connecting arm being pushed away, and a longer distance of support can be applied according to the potholes on the ground. When the ground is potholes or uneven, the height distance of the chassis support can be adjusted by adjusting the inclination angle of the second connecting arm being pushed away, which can ensure that the chassis can remain stable on uneven ground. For example, in a field work site, there may be potholes of various depths on the ground. This support method can ensure that the chassis is not affected by the potholes and the equipment can be placed stably.

[0024] 4. Through the design of the placement box, the closing cover, the second motor, the winch and the spring buckle, if any maintenance tools are forgotten during the maintenance of the power equipment, the ground staff can hang the maintenance tools on the spring buckle, and then start the second motor to drive the winch to reel in the rope, so that the spring buckle at the lower end of the rope can be pulled into the placement box. When the spring buckle is pulled into the placement box, the spring buckle will push the top of the closing cover open, and then the spring buckle will pull the maintenance tools into the placement box, so that the closing cover can fall naturally to close the bottom of the placement box, and the tools hung by the spring buckle can be placed in the placement box for the staff to take and use. This avoids the maintenance personnel from moving up and down frequently due to lack of tools, saves time, and improves the overall work efficiency of power equipment maintenance. For example, when repairing a power tower at a higher place, if the maintenance personnel finds that they have forgotten to bring a special wrench, they can quickly get the tools in this way, thereby reducing delays in maintenance work.

[0038] See also Figure 1-Figure 11 , this embodiment provides the following technical solutions:

[0039] like Figure 1-Figure 5 As shown, an auxiliary device for maintenance of electric power equipment comprises: a chassis 1, rollers 101 are rotatably mounted on both sides of the chassis 1, and support mechanisms 2 are rotatably mounted on both ends of the lower surface of the chassis 1, so that the support mechanisms 2 can support and raise the chassis 1;

[0040] Among them, a lifting mechanism 3 is rotatably installed on the upper surface of the chassis 1, a working platform 102 is fixedly installed on the upper surface of the lifting mechanism 3, a ladder 103 is fixedly installed at one end of the working platform 102, and the bottom of the ladder 103 is supported on the upper surface of the chassis 1, so that the staff can climb into the working platform 102 and can be lifted by the lifting mechanism 3;

[0041] Among them, one end of the work platform 102 is connected and installed with an equipment conveying mechanism 4, which can extend to the upper surface of the chassis 1 and can hang the required equipment to be rolled up and lifted up again by the equipment conveying mechanism 4 for the staff to take and use.

[0042] Through the design of the chassis 1, the working platform 102, the supporting mechanism 2, the lifting mechanism 3 and the tool conveying mechanism 4, when in use, the chassis 1 can be moved to the area that needs to be repaired by the rollers 101, and then the supporting mechanism 2 is started to support the chassis 1 according to the ground, and can be tilted and adjusted in height according to the terrain to ensure the levelness of the chassis 1. This adaptive adjustment capability can ensure that the working platform 102 is in a horizontal and stable state for maintenance work. For example, near the outdoor power tower base, there may be slopes or potholes on the ground, and the supporting mechanism 2 can be adjusted according to these terrains, thereby improving the applicability and stability of the entire device. After that, the staff can enter the working platform 102 through the ladder 103 and start the lifting mechanism 3 to lift the working platform 102 to the height required for maintenance for maintenance operations. In the process of maintenance, if any maintenance tools are forgotten, the staff below can hang the maintenance tools on the outer surface of the tool conveying mechanism 4 and pull them into the working platform 102. This function greatly improves the efficiency of maintenance work, avoids the staff from frequently going up and down the working platform 102 due to lack of tools, and ensures the continuity of maintenance work. In some complex maintenance tasks, timely obtaining the required tools can shorten the maintenance time, reduce the power outage time of equipment, and improve the reliability of power supply.

[0043] like Figure 6-Figure 7 As shown, the lifting mechanism 3 includes a frame plate 301, and docking plates 302 are fixedly installed at the four corners of the upper and lower surfaces of the frame plate 301. Support rods 303 are rotatably installed in the docking plate 302, and four groups of support rods 303 on the lower surface of the frame plate 301 are rotatably installed on the upper surface of the chassis 1, and the four groups of support rods 303 on the upper surface of the frame plate 301 are rotatably connected to the four groups of support rods 303 on the lower surface of another group of frame plate 301, and connecting rods 309 are rotatably installed between the four groups of support rods 303 on the left and right sides.

[0044] The lower surfaces of the two groups of connecting rods 309 are fixedly installed with transmission columns 310, and the two groups of transmission columns 310 are respectively threadedly installed on the outer surfaces of the positive thread rod 306 and the reverse thread rod 305, the positive thread rod 306 and the reverse thread rod 305 are fixedly connected together, the positive thread rod 306 and the reverse thread rod 305 are fixedly installed at one end of the output shaft of the first motor 304, the first motor 304 slides in the first guide cylinder 308, and the second guide cylinder 307 is slidably installed in the first guide cylinder 308, and the first guide cylinder 308 is fixedly installed on the upper surface of the chassis 1, so that when the positive thread rod 306 and the reverse thread rod 305 are driven to rotate by the first motor 304, the two groups of connecting rods 309 can be threadedly driven to push outward, thereby enabling the support rods 303 rotatably installed between the frame plates 301 to be pushed to the outer end and unfolded vertically, thereby increasing the spacing between the two groups of frame plates 301, and the upper surface of the uppermost frame plate 301 is fixedly installed with a working platform 102, so as to perform a jacking operation on the working platform 102.

[0045] When the support rod 303 rotatably installed between the two sets of frame plates 301 is pushed outward and expanded vertically, a square frame can be formed between the two sets of frame plates 301, and the expanded square frame can increase the bearing capacity while improving the stable supporting force.

[0046] When the frame plate 301 is pushed and unfolded, the positive threaded rod 306 and the reverse threaded rod 305 are also driven to rise for a certain distance, thereby driving the first motor 304 to slide vertically upward in the first guide cylinder 308 .

[0047] The first motor 304 between the two sets of frame plates 301 on the upper layer slides in the second guide cylinder 307 . When the two sets of frame plates 301 on the upper layer are pushed and unfolded, the first motor 304 can push the second guide cylinder 307 to slide upward in the first guide cylinder 308 .

[0048] Through the design of the frame plate 301, the support rod 303, the positive thread rod 306, the reverse thread rod 305, the first motor 304, the first guide cylinder 308 and the second guide cylinder 307, when the work platform 102 is supported, the three groups of first motors 304 can be started to drive the positive thread rod 306 and the reverse thread rod 305 to drive the two groups of connecting rods 309 to push outward, so that the support rods 303 rotatably installed between the frame plates 301 can be pushed outward and expanded to a vertical shape, so that a square frame can be formed between every two groups of frame plates 301. The expanded square frame structure has better stability in mechanics than a scissor lift, and can increase the bearing capacity of the work platform 102. During the maintenance of power equipment, the work platform 102 needs to bear the weight of maintenance personnel, maintenance tools and equipment, etc. This stable support structure can To ensure that the working platform 102 will not deform or collapse when bearing a large weight, and the frame plate 301 will also drive the positive threaded rod 306 and the reverse threaded rod 305 to rise a certain distance in the process of being pushed and unfolded, so as to drive the first motor 304 to slide vertically in the first guide cylinder 308, and the first motor 304 between the two sets of frame plates 301 on the upper layer slides in the second guide cylinder 307, so that the first motor 304 can push the second guide cylinder 307 to slide in the first guide cylinder 308 in the process of being pushed up. This linkage design enables the working platform 102 to automatically adapt to changes in height during the jacking process, without the need for additional complex operations to adjust the position of the first motor 304. This feature enables the working platform 102 to maintain a stable support structure and normal operating state under different working height requirements.

[0049] like Figure 8-Figure 9 As shown, the support mechanism 2 includes a docking rod 201, which is fixedly mounted on both sides of the lower surface of the chassis 1. A first connecting arm 202 is rotatably mounted on one end of the docking rod 201, a second connecting arm 205 is rotatably mounted on the lower surface of the first connecting arm 202, a universal ball 207 is fixedly mounted on the other end of the second connecting arm 205, and a support plate 208 is rotatably mounted on the outer surface of the universal ball 207.

[0050] A connecting plate 203 is fixedly installed at one end of the docking rod 201, and a first hydraulic rod 204 is rotatably installed in the connecting plate 203. The piston rod of the first hydraulic rod 204 is rotatably installed at one end of the first connecting arm 202, so that the first hydraulic rod 204 can push the first connecting arm 202 to flip and unfold. A second hydraulic rod 206 is rotatably installed on the lower surface of the first connecting arm 202, and the piston rod of the second hydraulic rod 206 is rotatably installed at one end of the second connecting arm 205, so that the second hydraulic rod 206 can push the second connecting arm 205 to flip and unfold. The flipping and unfolding of the first connecting arm 202 and the second connecting arm 205 can increase the supporting area of ​​the chassis 1, and the height distance supported by the chassis 1 can be adjusted by the tilt angle of the second connecting arm 205 being pushed open, and the pushing of the second connecting arm 205 can adjust the supporting position of the support plate 208.

[0051] Through the design of the first connecting arm 202, the second connecting arm 205, the first hydraulic rod 204, the second hydraulic rod 206, the universal ball 207 and the support plate 208, when supporting the chassis 1, the first hydraulic rod 204 can be activated according to the terrain area to push the first connecting arm 202 to the position of rotation and expansion, and because the support plate 208 at one end of the second connecting arm 205 is rotatably installed at one end of the first connecting arm 202, the support point position of the support plate 208 can be adjusted according to the angle position of the first connecting arm 202 flipped open, so that suitable support points can be found in terrain areas of different shapes and sizes. For example, when supporting equipment in irregular mountainous areas or narrow gaps between urban buildings, the support points can be flexibly adjusted according to the actual terrain to improve the adaptability of the chassis 1 support, and then the second hydraulic rod 206 can be activated to push the second connecting arm 2 05 is tilted and unfolded, and drives the support plate 208 to be supported on the ground, and the support plate 208 rotates the outer surface of the universal ball 207 installed on one end of the second connecting arm 205, so that the support plate 208 can be accurately fitted on the supporting point through the rotation of the universal ball 207, and the height distance supported by the chassis 1 can be adjusted by the tilt angle of the second connecting arm 205 being pushed open, and a longer distance of support can be applied according to the potholes on the ground. When the ground is potholes or uneven, the height distance of the chassis 1 can be adjusted by adjusting the tilt angle of the second connecting arm 205 being pushed open, so as to ensure that the chassis 1 can remain stable on uneven ground. For example, in a field work site, there may be potholes of various depths on the ground. This support method can ensure that the chassis 1 is not affected by the potholes, so that the equipment can be placed stably.

[0052] like Figure 10-11As shown, the tool conveying mechanism 4 includes a mounting frame 404, which is fixedly mounted on one end of the working platform 102, and a second motor 403 is fixedly mounted on one end of the mounting frame 404. The output shaft of the second motor 403 passes through the mounting frame 404 and a winch 405 is fixedly mounted on the end thereof. The winch 405 is rotatably mounted on the mounting frame 404, and a spring buckle 406 is fixedly connected to the head of the rope wound up on the outer surface of the winch 405.

[0053] The rope of the winch 405 passes through the upper surface of the placement box 401 to the lower surface. The placement box 401 is fixedly installed at one end of the working platform 102 and is located directly below the installation frame 404. There is a closing cover 402 that rotates inside the placement box 401. The closing cover 402 is flipped upward, so that the closing cover 402 can be pushed open when pulled by the spring buckle 406. After the spring buckle 406 is pulled into the placement box 401 by the rope, the closing cover 402 can naturally fall and close the bottom of the placement box 401, so that the instrument hung by the spring buckle 406 can be placed in the placement box 401.

[0054] Through the design of the storage box 401, the closing cover 402, the second motor 403, the winch 405 and the spring buckle 406, during the maintenance of the power equipment, if a maintenance tool is forgotten, the ground staff can hang the maintenance tool on the spring buckle 406, and then start the second motor 403 to drive the winch 405 to reel in the rope, so that the spring buckle 406 at the lower end of the rope can be pulled into the storage box 401. When the spring buckle 406 is pulled into the storage box 401, the spring buckle 406 will push the closing cover 402 open, and then the spring buckle 406 will After the maintenance tool is pulled into the placement box 401, the closing cover 402 can fall naturally to close the bottom of the placement box 401, and the tool hung by the spring buckle 406 can be placed in the placement box 401 for the staff to take and use. This avoids the maintenance personnel from moving up and down frequently due to lack of tools, saves time, and improves the overall work efficiency of power equipment maintenance. For example, when repairing a power tower at a higher place, if the maintenance personnel finds that they have forgotten to bring a special wrench, they can quickly get the tool in this way, thereby reducing delays in maintenance work.

[0055] The working steps of this scheme are summarized and sorted out according to the above technical scheme: when in use, the chassis 1 can be moved to the area that needs maintenance through the roller 101, and then the first hydraulic rod 204 can be started to push the first connecting arm 202 to the position of rotation and expansion according to the terrain area. Since the support plate 208 at one end of the second connecting arm 205 is rotatably installed at one end of the first connecting arm 202, the support point position of the support plate 208 can be adjusted according to the angle position of the first connecting arm 202 being flipped open, so that suitable support points can be found in terrain areas of different shapes and sizes. For example, when supporting equipment in irregular mountainous areas or narrow gaps between urban buildings, the support points can be flexibly adjusted according to the actual terrain to improve the adaptability of the chassis 1 support, and then The second hydraulic rod 206 can be activated to tilt and unfold the second connecting arm 205 and drive the support plate 208 to support the ground. The support plate 208 can rotate the outer surface of the universal ball 207 installed at one end of the second connecting arm 205, so that the support plate 208 can be accurately fitted to the support point through the rotation of the universal ball 207. The height distance supported by the chassis 1 can be adjusted by the tilt angle of the second connecting arm 205 being pushed open, and a longer distance of support can be applied according to the pitted surface of the ground. When the ground is pitted or uneven, the height distance of the chassis 1 can be adjusted by adjusting the tilt angle of the second connecting arm 205 being pushed open, so as to ensure that the chassis 1 can remain stable even on uneven ground, and then the workers can The worker enters the working platform 102 through the ladder 103 and starts the three first motors 304 to drive the positive threaded rods 306 and the reverse threaded rods 305 to drive the two connecting rods 309 to push outward, so that the support rods 303 rotatably installed between the frame plates 301 can be pushed outward and expanded to a vertical shape, so that a square frame can be formed between every two sets of frame plates 301. The expanded square frame structure has better mechanical stability than a scissor lift, and can increase the bearing capacity of the working platform 102. During the maintenance of power equipment, the working platform 102 needs to bear the weight of maintenance personnel, maintenance tools and equipment, etc. This stable support structure can ensure that the working platform 102 will not deform or collapse when bearing a large weight. The first motor 304 is able to slide vertically upward in the first guide cylinder 308, and the first motor 304 between the two sets of frame plates 301 on the upper layer slides in the second guide cylinder 307, so that the first motor 304 can push the second guide cylinder 307 to slide upward in the first guide cylinder 308 during the process of being pushed upward, until the working platform 102 is lifted to the height position where maintenance is required for maintenance. If maintenance tools are forgotten during the maintenance process, the staff below can hang the maintenance tools on the spring buckle 406, and then start the second motor 403 to drive the winch 405 to reel in the rope.Then, the spring buckle 406 at the lower end of the rope can be pulled into the storage box 401. When the spring buckle 406 is pulled into the storage box 401, the spring buckle 406 will push the closing cover 402 open. Then, after the spring buckle 406 pulls the maintenance tool into the storage box 401, the closing cover 402 can naturally fall down to close the bottom of the storage box 401, and the tool hung by the spring buckle 406 can be placed in the storage box 401 for the staff to take and use.

[0056] In summary: the device can tilt and adjust the height position accordingly according to the terrain to ensure the levelness of the chassis 1. This adaptive adjustment capability can ensure that the working platform 102 is in a level and stable state for maintenance work. If any maintenance tools are forgotten during the maintenance process, the maintenance tools can be transported into the working platform 102 through the tool conveying mechanism 4. This function greatly improves the efficiency of the maintenance work, avoids the staff from frequently going up and down the working platform 102 due to lack of tools, and ensures the continuity of the maintenance work.
