The rod 6 rotates to ensure the stability of the entire device during movement. The bottom of the vehicle body 1 is equipped with tracks 3, which can move the entire device and change direction simultaneously. Each track 3 has several moving gears 301 meshing inside, which can drive the track 3 to rotate. Each set of moving gears 301 has stabilizing plates 304 on both its inner and outer sides. The stabilizing plates 304 are made of alloy material and are used to position the moving gears 301. Reversing rods 7 are slidably connected to both the left and right ends of the vehicle body 1. The reversing rods 7 are made of alloy material and are used to position the adapter rods 701. Each reversing rod 7 has a reversing auxiliary gear 704 fixed externally. A reversing main gear 705 is meshed with the inner side of wheel 704. The reversing main gear 705, by rotating, drives the reversing secondary gear 704 to rotate, thereby driving the reversing rod 7 to rotate. This ensures the entire device remains horizontal on the inclined clamp, guaranteeing operator safety when boarding. Each reversing rod 7 has an adapter rod 701 slidably connected inside. The adapter rod 701 is made of alloy material and is used to position the support block 801. Each adapter rod 701 has a stabilizing rod 8 at its outer end.

A layer of rubber material is fixed to the bottom to achieve anti-slip purpose. Each support plate 802 is slidably connected to a flange 803, which is made of alloy material. A layer of rubber material is fixed to the bottom of the flange 803 to ensure anti-slip properties. At the same time, the flange 803 is provided with several through holes, so that the entire device can be adapted to clamps with bolt holes as well as smooth clamps, thereby improving the applicability of the entire device. Several sets of lifting frames 2 are provided on the top of the vehicle body 1. The lifting frames 2 are made of alloy material and are used to position the lifting plate 202. Each set of lifting frames 2 has locking rods 9 at both the front and rear ends. The locking rods 9 are retractable, so as to fit tightly with the locking holes 902.This locks the locking plate 901, thereby locking the lifting plate 202. Each set of lifting frames 2 has a slidingly connected lifting plate 202 inside. The lifting plate 202 is made of alloy material. The outer lifting plate 202 supports the lifting frame 2 on top of it, and the innermost lifting plate 202 supports the lifting box 5. The lifting box 5, also made of alloy material, is fixed to the top of the innermost lifting plate 202. The lifting box 5 is convenient for the operator to board and alight from. A door 501 is rotatably connected to the front end of the lifting box 5. The lifting box 5 can be locked to ensure operator safety. Several hinge blocks 403, made of alloy material, are fixed to the top of the innermost lifting frame 2. These hinge blocks 403 are used to position the diagonal brace 4. Each hinge block 403 has a diagonal brace 4 hinged inside. The diagonal brace 4 is telescopic, allowing the pressure sensor 401 to rise and fall. Each diagonal brace 4 has a diagonal brace plate 402 at its bottom, made of alloy material. Rubber material is fixed to the bottom of the diagonal brace plate 402 to ensure anti-slip properties.

[0021] Example 2, based on Example 1, is... Figures 4-5 , Figures 7-9As shown, two tilting motors 601 are fixed on the vehicle body 1. The tilting motors 601 can drive the tilting rods 6 to rotate. Each tilting motor 601 is rotatably connected to one end of the tilting rod 6. Each tilting rod 6 and the tilting block 602 is provided with a tilting locking hole 604. The tilting locking hole 604 cooperates with the tilting locking rod 603 to prevent the tilting locking rod 603 from rotating, thereby preventing the tilting rod 6 from rotating on its own, thus ensuring the stability of the entire device. The telescopic end of the tilting locking rod 603 is slidably connected to the tilting locking hole 604. The tilting block 602 is fixedly connected to the outer stabilizing plate 304. Several movable bearings 305 are fixed on each inner stabilizing plate 304. 305 is used to position the moving gear 301. The inner ring of each moving bearing 305 is fixedly connected to the shaft of the moving gear 301 at one end. The outer end of the shaft of each moving gear 301 is rotatably connected to the outer stabilizing plate 304. The shaft of the leftmost moving gear 301 is rotatably connected to a moving motor 306, which can drive the moving gear 301 to rotate. The moving motor 306 is fixedly connected to the inner stabilizing plate 304. A moving camera 101 is fixed to the top right end of the vehicle body 1. The moving camera 101 is used to observe the movement of the entire device. Two levels 102 are fixed to the top left end of the vehicle body 1. The levels 102 are used to monitor the levelness of the entire device. To ensure the lifting box 5 remains level and thus guarantee operator safety, a vehicle anti-slip plate 103 made of rubber is fixed to the bottom of the vehicle body 1 to prevent the entire device from sliding and ensure its stability. Several reversing slots 104 are provided at both ends of the vehicle body 1. These slots are used to position the steering wheel 702, thereby positioning the reversing lever 7. A steering wheel 702, made of alloy material, is slidably connected inside each slot 104. Each steering wheel 702 is fixedly connected to the reversing lever 7 within it. A seatbelt positioning rod 50 is fixed to the top of the lifting box 5. 5. The safety belt positioning rod 505 facilitates the operator's fastening of the safety belt, thus ensuring the operator's safety. A toolbox 504 is also fixed inside the lifting box 5, providing convenient storage for tools. A controller 502 is fixed to the left end of the toolbox 504, controlling the entire device. A battery 503 is fixed to the rear end of the controller 502, providing the necessary power to the entire device. A positioning strip 512, made of alloy material, is tightly fitted to the rear end of the lifting box 501, providing fixed connection to the lifting box 5. The positioning strip 507 is used to position the lifting box 501. A locking block 511, also made of alloy material, is fixed to the front left side of the lifting box 5.The locking block 511 is used to position the lock head 508. The lock head 508 is slidably connected within the groove of the locking block 511. The lock head 508 cooperates with the locking block 511 to lock the cabinet door 501. Several locking rods 509 are fixed to the right side of the lock head 508. The locking rods 509 are made of alloy material and are used to position the lock head 508. The several locking rods 509 are fixedly connected to each other by a cabinet door handle 506. The cabinet door handle 506 allows the operator to easily pull the lock head 508 to open the cabinet door 501. Each locking rod 509 is externally equipped with a locking spring 510. The locking spring 510 is elastic, thereby ensuring that the lock head 508 is tightly attached to the locking block 511. A fixing strip 507 is slidably connected to the several locking rods 509. The fixing strip 507 is used to position the locking rod 509 and is fixedly connected to the cabinet door 501. When using this device, the operator places the entire device on the clamping plate. The operator then uses the controller 502 to control the two moving motors 306, which drive the moving gears 301, thereby rotating the two tracks 3. This allows the entire device to move and change direction. The controller 502 can observe the relationship between the entire device and the required maintenance position via the top camera 201. When the device moves to the required position, if the clamping plate is horizontal, the controller 502 controls the two tilting motors 601 to operate, thereby rotating the tilting rod 6. At this time, the universal wheels 303 allow the two tracks 3 to move outwards. The tilting block 602 causes the vehicle body 1 to descend. When the anti-slip plate 103 is in close contact with the clamping plate, the anti-slip plate 103... To ensure the stability of the entire device, when the entire device needs to be moved, the controller 502 controls the flip motor 601 to work in reverse, thereby driving the flip rod 6 to rotate to a vertical position. At this time, the controller 502 controls the flip locking rod 603 to extend, so that the telescopic end of the flip locking rod 603 is tightly attached to the flip locking hole 604, thereby ensuring the stability of the entire device when it is moved. When it is necessary to board the lifting box 5, the operator pulls the box door handle 506 to drive the lock head 508 to move, thereby facilitating the opening of the box door 501. When the operator boards the lifting box 5, the operator releases the box door handle 506. At this time, due to the action of the locking rod 509 and the locking spring 510, the lock head 508 is tightly attached to the locking block 511, thereby ensuring the stability of the lifting box 5 and ensuring the safety of the operator.

[0022] Example 3, based on Example 1, is... Figures 12-14 , Figures 17-19The vehicle body 1 has grooves 710 in the recesses at both ends. These grooves 710 are used to position the positioning blocks 707. Each groove 710 has a slidably connected positioning block 707 made of alloy material. The positioning blocks 707 are used to position the reversing main gear 705, thereby ensuring the stability of the reversing rod 7 and the entire device. Each positioning block 707 has a reversing main gear 705 tightly fitted to its outer side. The reversing main gear 705 can drive the reversing rod 705 to rotate. Each reversing main gear 705 meshes with a reversing secondary gear 704 at one end. The reversing secondary gear 704, by rotating, can drive the reversing rod 7 to rotate. A commutator motor 706 is rotatably connected to the front end of the main gear 705. The commutator motor 706 can drive the main gear 705 to rotate. Each commutator motor 706 is fixedly connected to the vehicle body 1. A positioning rod 709 is fixedly fixed to the front end of each positioning block 707. The positioning rod 709 is telescopic, thereby driving the positioning block 707 to move back and forth, thus facilitating the locking of the main gear 705. The other end of each positioning rod 709 is fixedly connected to the vehicle body 1. A commutator camera 708 is provided at the top of each positioning rod 709 and fixedly connected to the vehicle body 1. The commutator camera 708 is used to observe the position of the positioning block 707. Each commutator 709 has two sets of positioning holes 703. The positioning holes 703 are used for... For positioning the adapter head 713, each adapter rod 701 has an adapter shaft 711 fixed inside. The adapter shaft 711 is made of alloy material and is used to position the adapter head 713. Each adapter shaft 711 has an adapter head 713 slidably connected to its exterior. The adapter head 713 is also made of alloy material. The adapter head 713 and the positioning hole 703 cooperate to lock the adapter rod 701, thereby facilitating the movement of the stabilizing rod 8 and ensuring the stability of the entire device. Each adapter shaft 711 is also provided with an adapter spring 712 on its exterior. The adapter spring 712 is elastic, thereby ensuring that the adapter head 713 can fit tightly against the positioning hole 703 when no force is applied. Each adapter head 713 can be aligned with its top. The positioning holes 703 of the part fit tightly. Two support blocks 801 are fixed to the outer end of each adapter rod 701. The support blocks 801 are used to position the stabilizer rod 8, thereby ensuring the stability of the rise and fall of the stabilizer rod 8. Each support block 801 is slidably connected to one end of the stabilizer rod 8. A positioning ring 805, made of alloy material, is slidably connected between the two support blocks 801 in each group. The positioning ring 805 is used to position the screw tube 804. A screw tube 804, also made of alloy material, is fixed between the two positioning rings 805. Rotation of the screw tube 804 can drive the stabilizer rod 8 to rise and fall, thereby driving the support plate 802 to rise and fall, thus supporting the entire device.Each solenoid 804 is engaged with the internal stabilizer bar 8. A telescopic secondary gear 806 is fixed externally to each solenoid 804. Each telescopic secondary gear 806 is engaged with a telescopic main gear 807. A telescopic motor 808 is rotatably connected to the top of each telescopic main gear 807. The telescopic motor 808 can drive the telescopic main gear 807 to rotate, thereby driving the telescopic secondary gear 806 to rotate, which in turn drives the solenoid 804 to rotate, thus causing the stabilizer bar 8 to rise and fall. Each telescopic motor 808 is fixedly connected to a support block 801 at one end. When the clamping plate is horizontal, after the controller 502 controls the anti-slip plate 103 of the vehicle body to be tightly attached to the clamping plate, the controller 502 controls the telescopic motor 808 to work, thereby driving the telescopic main gear 807 to rotate, thereby driving the telescopic secondary gear 806 to rotate, thereby driving the solenoid 804 to rotate, thereby driving the stabilizer bar 8 to rotate, thereby driving the support plate 802 to rotate, so that the flange 803 is tightly attached to the clamping plate. At this time, if there are pre-set screws or bolt holes on the clamping plate, the operator can adjust the flange 803 to make the entire device... The device is fixed to the clamping plate to ensure the stability of the entire device. If the maintenance position required is the top mechanism of the clamping plate ramp, when the anti-slip plate 103 of the vehicle body is in close contact with the ramp clamping plate, the flange 803 is in close contact with the ramp. The controller 502 controls the reversing motor 706 to work, thereby driving the reversing main gear 705 to rotate, thereby driving the reversing secondary gear 704 to rotate, thereby causing the stabilizer bar 8 to rotate to the vertical position. At this time, the controller 502 controls the telescopic motor 808 to work again according to the value of the level 102, thereby making the vehicle body... 1. Rotation causes the vehicle body 1 to rotate to a horizontal position. At this point, the rubber layer at the bottom of the flange 803 and the support plate 802 prevents the entire device from sliding, ensuring its stability. Furthermore, bolt holes in the clamping plate further enhance stability. The cooperation of the telescopic motor 808 and the reversing motor 706 allows the vehicle body 1 to rotate to a horizontal position, enabling the operator to enter the lifting box 5 and attach the safety belt to the safety belt positioning rod 505, ensuring operator safety. Further, the operator... By moving the adapter rod 701, the support block 801 can be moved, thereby causing the stabilizing rod 8 to move outward. When it moves to the desired position, the adapter spring 712 and the adapter shaft 711 ensure that the adapter head 713 is in close contact with the positioning hole 703, thus ensuring the stability of the adapter rod 701. This allows the position of the support plate 802 to be controlled according to the required height of the lifting box 5, thereby ensuring the stability of the vehicle body 1, the lifting box 5, and the operator's safety.

[0023] Example 4, based on Example 1, is... Figure 10 , Figures 20-21The outermost two sets of lifting frames 2 are fixedly connected to the bottom of the vehicle body 1. The middle lifting frame 2 is fixedly connected to the lifting plate 202 at its bottom. The top of the innermost left lifting frame 2 is fixedly equipped with a top camera 201. The top camera 201 can ensure the bottom of the lifting box 5 is at the required maintenance position by observing the top of the lifting frame 2, thus ensuring the accuracy of the entire maintenance process and the lifting effect. Each lifting frame 2 is also fixedly equipped with a laser displacement meter 207. The laser displacement meter 207 can determine the lifting height of the lifting plate 202 by monitoring the distance between the laser displacement meter 207 and the lifting plate 202. Thus, the height of the lifting box 5 can be determined by the laser displacement meter 207, thereby ensuring the lifting effect. To ensure the accuracy of the lifting and thus guarantee the lifting effect, a lifting motor 203 is fixed to the top of each lifting frame 2. The lifting motor 203 can drive the lifting screw 205 to rotate. A lifting screw 205 is rotatably connected to the bottom of each lifting motor 203. The lifting screw 205, by rotating, can drive the lifting plate 202 to rise and fall. Each lifting screw 205 is meshed with the external lifting plate 202. A lifting bearing 204 is fixed to the bottom of each lifting screw 205. The lifting bearing 204 is used to position the lifting screw 205. The outermost ring of the lifting bearing 204 is fixedly connected to the vehicle body 1, and the remaining lifting bearings 204 are fixedly connected to the lifting plate 202 at their bottom. Each set... The lifting frame 2 has several locking holes 902 at both its front and rear ends. These locking holes 902 are used to position the locking rod 9, thereby locking the locking plate 901 and the lifting plate 202, ensuring the stability of the entire device. Each lifting plate 202 has a locking plate 901 fixed at both its front and rear ends. The locking plate 901 is made of alloy material, and a locking rod 9 is fixed to the outer end of each locking plate 901. The locking rod 9 is telescopic, and its telescopic end is slidably connected to the locking hole 902 on its inner side. Each diagonal brace 4 has a pressure sensor 401 hinged to its bottom. The pressure sensor 401 monitors the pressure on the diagonal brace 402, thereby monitoring whether the diagonal brace 4 is monitoring the entire device. To ensure the stability of the entire device, each pressure sensor 401 is fixedly connected to its bottom inclined support plate 402. Each hinge block 403 has a spreading motor 404 fixed to one end, which can drive the inclined support rod 4 to rotate. Each spreading motor 404 is rotatably connected to the shaft of the inclined support rod 4 at one end. A spreading plate 405, made of alloy material, is fixed to the other end of the shaft of each inclined support rod 4. The spreading plate 405 is used to position the inclined support locking rod 406. A inclined support locking rod 406 is fixed to each spreading plate 405. The inclined support locking rod 406 is telescopic, allowing it to fit tightly against the inclined support locking main hole 407 and the inclined support locking secondary hole 408.To ensure the stability of the diagonal brace 4, each hinge block 403 has two diagonal brace locking main holes 407 at one end near the expansion plate 405, with an included angle of 45° between the two diagonal brace locking main holes 407, thus ensuring the stability of the entire support device. Each diagonal brace 4 also has a diagonal brace locking secondary hole 408 at one end near the expansion plate 405. The diagonal brace locking secondary hole 408 is used to ensure the stability of the diagonal brace 4, and the diagonal brace locking rod 406 can fit tightly with the diagonal brace locking main holes 407 and the diagonal brace locking secondary holes 408. Once the entire device is fully positioned, the operator remotely controls the controller 502 to coordinate the operation of several lifting motors 203, thereby rotating several lifting screws 205 and raising or lowering the lifting plate 202. At this time, several laser displacement gauges 207 monitor the height of the lifting box 5. When the lifting box 5 reaches the desired height, the operator can easily move the adapter rod 701 based on the forces acting on the entire device, ensuring its stability. The operator then controls the lifting box 5 to reset, allowing them to climb inside and lock the door 501. The operator then uses the controller 502 to raise the lifting box 5 again to the desired maintenance height. The controller 502 then extends the locking rod 9, locking the device. Rod 9 engages with the locking hole 902, thereby ensuring the stability of the locking plate 901, the lifting plate 202, and the lifting box 5. At this time, the operator controls the opening motor 404 to rotate, which in turn drives the diagonal brace 4 to rotate, causing the diagonal brace 4 to tilt. Furthermore, the controller 502 controls the diagonal brace locking rod 406 to extend, causing it to fit tightly against the diagonal brace locking main hole 407 and the diagonal brace locking secondary hole 408, thus ensuring the stability of the diagonal brace 4. Further, the controller 502 controls the diagonal brace 4 to extend, thereby moving the pressure sensor 401, causing the diagonal brace plate 402 to fit tightly against the clamping plate, further ensuring the stability of the entire device, ensuring operator safety, and facilitating maintenance.

[0024] The workflow of this invention is as follows: When using this device, the operator places the entire device on the clamping plate. At this time, the operator controls the two moving motors 306 through the controller 502 to drive the moving gears 301, thereby driving the two tracks 3 to rotate. This allows the entire device to move and change direction. The controller 502 can observe the relationship between the entire device and the required maintenance position through the top camera 201. When the entire device moves to the required position, if the clamping plate is horizontal, the controller 502 controls the two tilting motors 601 to operate, thereby driving the tilting rod 6 to rotate. At this time, due to the action of the casters 303, the two tracks 3 can move outwards. Then, due to the action of the tilting block 602... The vehicle body 1 is lowered. When the anti-slip plate 103 is in close contact with the clamping plate, the anti-slip plate 103 ensures the stability of the entire device. When the entire device needs to be moved, the controller 502 controls the flipping motor 601 to work in reverse, thereby driving the flipping rod 6 to rotate to the vertical position. At this time, the controller 502 controls the flipping locking rod 603 to extend, so that the telescopic end of the flipping locking rod 603 is in close contact with the flipping locking hole 604, thereby ensuring the stability of the entire device during movement. If the clamping plate is horizontal, after the controller 502 controls the anti-slip plate 103 to be in close contact with the clamping plate, the controller 502 controls the telescopic motor 808 to work, thereby driving the telescopic main gear 80. 7 rotates, thereby driving the telescopic secondary gear 806 to rotate, which in turn drives the solenoid 804 to rotate, which in turn drives the stabilizer bar 8 to rotate, which in turn drives the support plate 802 to rotate, thus making the flange 803 tightly attached to the clamping plate. At this time, if there are pre-set screws or bolt holes on the clamping plate, the operator can use the flange 803 to fix the entire device to the clamping plate, thereby ensuring the stability of the entire device. If the maintenance position required is the top mechanism of the clamping plate ramp, when the vehicle anti-slip plate 103 is tightly attached to the ramp clamping plate, the flange 803 is tightly attached to the ramp. At this time, the controller 502 controls the reversing motor 706 to work, thereby driving the reversing main gear 705 to rotate, which in turn drives the reversing secondary gear 704 to rotate. The movement causes the stabilizer bar 8 to rotate to a vertical position. At this time, the controller 502 controls the telescopic motor 808 to work again based on the value of the level instrument 102, causing the vehicle body 1 to rotate and thus rotate to a horizontal position. The flange 803 and the rubber layer at the bottom of the support plate 802 prevent the entire device from sliding, ensuring its stability. Furthermore, bolt holes in the clamping plate further ensure stability. The cooperation of the telescopic motor 808 and the reversing motor 706 allows the vehicle body 1 to rotate to a horizontal position. At this point, the operator can enter the lifting box 5 and attach the safety belt to the safety belt positioning rod 505, ensuring the operator's safety.Furthermore, the operator can move the support block 801 by moving the adapter rod 701, thereby moving the stabilizing rod 8 outward. When it moves to the desired position, the adapter spring 712 and the adapter shaft 711 ensure that the adapter head 713 is tightly attached to the positioning hole 703, thus ensuring the stability of the adapter rod 701. This allows the position of the support plate 802 to be controlled according to the required height of the lifting box 5, ensuring the stability of the vehicle body 1, the lifting box 5, and the operator's safety. Once the entire device is fully positioned, the operator can remotely... The controller 502 controls several lifting motors 203 to work together, thereby driving several lifting screws 205 to rotate, which in turn drives the lifting plate 202 to rise and fall. At this time, several laser displacement gauges 207 monitor the height of the lifting box 5. When the lifting box 5 rises to the desired height, the operator can easily move the adapter rod 701 according to the force exerted on the entire device, thus ensuring the stability of the entire device. Furthermore, the operator controls the lifting box 5 to reset. The operator pulls the door handle 506 to move the lock head 508, thus easily opening the door 501. When the operator boards the... When inside the lifting box 5, the operator releases the door handle 506. At this time, due to the action of the locking rod 509 and the locking spring 510, the lock head 508 is tightly pressed against the locking block 511, ensuring the stability of the lifting box 5 and thus the operator's safety. The operator then uses the controller 502 to control the lifting box 5 to rise again to the required maintenance height. The controller 502 then controls the locking rod 9 to extend, causing it to engage with the locking hole 902, thus ensuring the stability of the locking plate 901, and consequently the lifting plate 202, and ultimately the lifting box 5. At this time, the operator controls the opening motor 404 to rotate, thereby driving the diagonal brace 4 to rotate, causing the diagonal brace 4 to tilt. Furthermore, the controller 502 controls the diagonal brace locking rod 406 to extend, causing the diagonal brace locking rod 406 to fit tightly against the diagonal brace locking main hole 407 and the diagonal brace locking secondary hole 408, thus ensuring the stability of the diagonal brace 4. Further, the controller 502 controls the diagonal brace 4 to extend, thereby driving the pressure sensor 401 to move, causing the diagonal brace plate 402 to fit tightly against the clamping plate, further ensuring the stability of the entire device, thus ensuring operator safety and facilitating maintenance.
