and in the in-process that workstation 220 goes up and down for frame 210, the position of tool bogie 230 is unchangeable for workstation 220, thereby can pass through such a mode, power output through tool bogie 230's power pack drives workstation 220 and goes up and down, and then change the height of tool bogie 230, thereby be convenient for overhaul the in-process to power equipment at the maintainer, for the maintainer provides electric power maintenance equipment 200 in the tool bogie 230, and then overhaul the in-process to power equipment at the maintainer, reduce the maintenance work degree of difficulty of power equipment, and improve the efficiency of overhauing, reduce maintainer's intensity of labour.

Further, referring to fig. 1-4, in the present embodiment, the electric power overhaul apparatus 200 includes a first movable wheel set 250 and a second movable wheel set 260, the first movable wheel set 250 and the second movable wheel set 260 are both rotatably connected to the workbench 220, the first movable wheel set 250 and the second movable wheel set 260 are both in transmission connection with the transmission shaft 241, and the first movable wheel set 250 and the second movable wheel set 260 are arranged at intervals along a direction (as indicated by an arrow a in fig. 1-3) in which the tool car 230 enters the workbench 220;

in order to enable the power assembly of the tool car 230 to drive the table 220 to move up and down relative to the frame 210, the first movable wheel set 250 abuts against the front wheel 231 of the tool car 230, the second movable wheel set 260 abuts against the rear wheel 232 of the tool car 230, and the first movable wheel set 250 and the second movable wheel set 260 are used for maintaining the position of the tool car 230 relative to the table 220 and driving the transmission shaft 241 to rotate so as to drive the table 220 to move up and down relative to the frame 210 when the power assembly drives the front wheel 231 and the rear wheel 232 of the tool car 230 to rotate.

Thus, since the first movable wheel set 250 abuts against the front wheel 231 of the tool wagon 230, the second movable wheel set 260 abuts against the rear wheel 232 of the tool wagon 230, the first movable wheel set 250 and the second movable wheel set 260 are both rotatably connected to the worktable 220, and the first movable wheel set 250 and the second movable wheel set 260 are both drivingly connected to the transmission shaft 241, so that when the power assembly of the tool wagon 230 drives the front wheel 231 and the rear wheel 232 of the tool wagon 230 to rotate, the first movable wheel set 250 and the second movable wheel set 260 can be driven to rotate relative to the working platform 220, and because the first movable wheel set 250 and the second movable wheel set 260 are both in transmission connection with the transmission shaft 241, the transmission shaft 241 is connected with the worm wheel 243, and the worm wheel 243 is matched with the worm 242, so that when the transmission shaft 241 rotates, the worm 242 can be driven to rotate relative to the frame 210, the table 220 engaged with the worm 242 is further driven to move up and down with respect to the frame 210 in this manner; in the process that the workbench 220 is lifted relative to the frame 210, because the front wheels 231 and the rear wheels 232 of the tool car 230 rotate in the process of driving the first movable wheel set 250 and the second movable wheel set 260 to rotate, the position of the tool car relative to the workbench 220 is kept unchanged, the tool car 230 can be lifted synchronously with the workbench 220, and thus in such a way, the height of the tool car 230 can be increased, so that a maintenance worker can use maintenance equipment placed in the tool car 230 conveniently, and further in such a way, the maintenance worker can perform maintenance work on the power equipment conveniently, and the maintenance work is prevented from being influenced by the maintenance equipment, so that the maintenance difficulty is reduced, the maintenance efficiency is improved, and the labor intensity of the maintenance worker is reduced. In this embodiment, the rotation directions of the front wheel 231 and the rear wheel 232 can be controlled by controlling the power assembly, and the lifting direction of the table 220 with respect to the frame 210 can be controlled by controlling the directions of the front wheel 231 and the rear wheel 232.

Referring to fig. 5 and 6 in conjunction with fig. 1 and 2, fig. 5 and 6 show structures of a table, a first driving roller and a second driving roller in other embodiments of the present invention; in other embodiments of the present invention, in order to enable the front wheels 231 and the rear wheels 232 of the tool car 230 to drive the worktable 220 to ascend and descend, the electric power overhaul apparatus 200 further includes two first driving rollers 271 and two second driving rollers 272; the two first driving rollers 271 and the two second driving rollers 272 are arranged at intervals along a direction (a direction indicated by an arrow a in fig. 5) in which the tool wagon 230 is driven into the work table 220; because the electric power overhaul equipment 200 comprises two sets of transmission mechanisms 240, two first transmission rollers 271 and two second transmission rollers 272 are both rotatably connected with the workbench 220, the two first transmission rollers 271 and the two second transmission rollers 272 respectively correspond to the set of transmission mechanisms 240, and the two first transmission rollers 271 and the two second transmission rollers 272 are respectively in transmission connection with the transmission shafts 241 of the two sets of transmission mechanisms 240; namely, the two first driving rollers 271 and the two second driving rollers 272 are respectively arranged in a delta shape with the driving shafts 241 of the corresponding driving mechanisms 240, and the two first driving rollers 271 and the two second driving rollers 272 are in driving connection with the corresponding driving shafts 241 through gears; two first driving rollers 271 are disposed side by side and are each adapted to abut against the front wheel 231 of the tool cart 230, and two second driving rollers 272 are disposed side by side and are each adapted to abut against the rear wheel 232 of the tool cart 230; that is, the two first driving rollers 271 and the two second driving rollers 272 are respectively arranged in a delta shape with the driving shafts 241 of the corresponding driving mechanisms 240, and the two first driving rollers 271 and the two second driving rollers 272 are both in driving connection with the corresponding driving shafts 241 through gears.

The two first driving rollers 271 and the two second driving rollers 272 are used to maintain the position of the tool wagon 230 with respect to the table 220 and to drive the driving shaft 241 to rotate when the front wheel 231 and the rear wheel 232 of the tool wagon 230 rotate, thereby driving the table 220 to ascend and descend. Therefore, when the tool car 230 is located on the workbench 220 and the front wheel 231 and the rear wheel 232 of the tool car 230 are respectively abutted with the two first driving rollers 271 and the two second driving rollers 272, the two first driving rollers 271 and the two second driving rollers 272 are both rotatably connected with the workbench 220 and are both in transmission connection with the transmission shaft 241; therefore, the front wheel 231 and the rear wheel 232 can drive the two first transmission rollers 271 and the two second transmission rollers 272 to rotate under the driving action of the power assembly, so that the transmission shaft 241 can be driven to rotate, and the working table 220 can be driven to move up and down relative to the frame 210 through the matching of the worm wheel 243 and the worm 242.

Referring to fig. 1 and 7, fig. 7 shows a structure of the workbench in a second position according to an embodiment of the present invention, in the embodiment, the workbench 220 has a first position (as shown in fig. 1) engaged with the worm 242 and a second position (as shown in fig. 2) disengaged from the worm 242; when the workbench 220 is located at the first position, the rotation of the front wheels 231 and the rear wheels 232 of the tool cart 230 located on the workbench 220 can drive the workbench 220 to ascend and descend relative to the frame 210.

When the workbench 220 is at the second position, the workbench 220 is located at the bottom of the frame 210, and the first movable wheel set 250 and the second movable wheel set 260 contact the ground and support the frame 210; in the process, since the workbench 220 is disengaged from the worm 242, the relative position of the electric power overhaul device 200 on the ground can be conveniently changed by the rolling contact between the first movable wheel set 250 and the second movable wheel set 260 and the ground. In this process, since the first movable wheel set 250 and the second movable wheel set 260 are in transmission connection with the transmission shaft 241, the transmission shaft 241 is connected with the worm wheel 243, and the worm wheel 243 is engaged with the worm 242, the rotation of the first movable wheel set 250 and the second movable wheel set 260 drives the worm 242 to rotate through the transmission shaft 241 and the worm 242, but since the workbench 220 is disengaged from the worm 242 at this time, the rotation of the worm 242 does not drive the workbench 220 to ascend and descend, so that the electric power overhaul device 200 does not interfere with the ascending and descending movement of the workbench 220 through the movement of the first movable wheel set 250 and the second movable wheel set 260 on the ground.

It should be noted that, when the workbench 220 is located at the second position, the tool cart 230 may be located on the workbench 220 or outside the workbench 220, and in order to enable the first movable wheel set 250 and the second movable wheel set 260 to support the electric power overhaul device 200, at this time, the movement of the workbench 220 relative to the frame 210 needs to be limited, that is, the workbench 220 and the frame 210 need to be fixedly connected. At this time, in order to fix the worktable 220, the power overhaul apparatus 200 further includes a supporting block 201 movably connected to the frame 210; the supporting block 201 is used for moving towards the ground relative to the frame 210 under the action of external force, and is abutted with the ground so as to support the frame 210. Therefore, when the supporting block 201 moves towards the ground relative to the frame 210 under the action of external force and abuts against the ground, the bottom of the frame 210 can be spaced from the ground, so that a space for the movement of the worktable 220 is reserved, the frame 210 is prevented from contacting with the ground, and the movement of the worktable 220 to the second position is interfered; when the workbench 220 is moved to the second position and the workbench 220 is fixed to the frame 210, the supporting block 201 can be retracted, so that the frame 210 is in rolling contact with the ground through the first movable wheel set 250 and the second movable wheel set 260, and at this time, the electric power overhaul device 200 can be conveniently moved.

Further, referring to fig. 1-4, in the present embodiment, when the first movable wheel set 250 and the second movable wheel set 260 are disposed, in order to enable the front wheel 231 and the rear wheel 232 of the tool wagon 230 on the workbench 220 to simultaneously abut against the first movable wheel set 250 and the second movable wheel set 260 and drive the first movable wheel set 250 and the second movable wheel set 260 to rotate, a wheel spacing between the first movable wheel set 250 and the second movable wheel set 260 is greater than a wheel spacing between the front wheel 231 and the rear wheel 232 of the tool wagon 230, and the tool wagon 230 is disposed between the first movable wheel set 250 and the second movable wheel set 260. In addition, in order to prevent the position of the tool wagon 230 from being changed with respect to the table 220 during the rotation of the tool wagon, when the front wheel 231 and the rear wheel 232 of the tool wagon 230 are respectively in contact with the first movable wheel set 250 and the second movable wheel set 260, the front wheel 231 and the rear wheel 232 of the tool wagon 230 are out of contact with the table 220. Therefore, the front wheels 231 and the rear wheels 232 of the tool wagon 230 are spaced from the ground, and the position of the tool wagon 230 relative to the workbench 220 is prevented from being changed due to the contact between the front wheels 231 and the rear wheels 232 and the workbench 220 in the rotating process of the front wheels 231 and the rear wheels 232 of the tool wagon 230.

It should be noted that, in the present embodiment, in order to improve the operation stability of the workbench 220, when the transmission mechanism 240 is provided, the electric power overhaul device 200 includes two sets of transmission mechanisms 240, and the two sets of transmission mechanisms 240 are respectively in transmission connection with the front wheels 231 and the rear wheels 232 of the tool car 230; that is, one of the transmission mechanisms 240 is in transmission connection with the first movable wheel set 250 and the front wheel 231 of the tool car 230, and the other transmission mechanism 240 is in transmission connection with the second movable wheel set 260 and the rear wheel 232 of the tool car 230, and in this process, since the power assembly drives the front wheel 231 and the rear wheel 232 of the tool car 230 to synchronously rotate, the two transmission mechanisms 240 synchronously move, so that the stability of the lifting operation of the worktable 220 can be improved.

Further, referring to fig. 1 to 4, in the present embodiment, in order to enable the tool car 230 to drive the front wheel 231 and the rear wheel 232 to rotate through the power assembly and to be able to move into or out of the workbench 220, the electric power overhaul device 200 further includes a brake assembly, which is connected to the workbench 220 and is used for limiting the rotation of the transmission shaft 241. Therefore, when the tool car 230 is driven into or out of the workbench 220, the rotation of the transmission shaft 241 can be limited through the brake assembly, so that the rotation of the first movable wheel set 250 and the second movable wheel set 260 can be limited, and further, the rotation of the front wheel 231 and the rear wheel 232 of the tool car 230 can drive the tool car 230 to move relative to the workbench 220, so that the tool car 230 can be driven into or out of the workbench 220; in the process of raising and lowering the table 220, the worm 242 is driven to rotate by the rotation of the front wheel 231 and the rear wheel 232 of the tool wagon 230, so that the restriction of the rotation of the transmission shaft 241 by the brake assembly is eliminated. In addition, in other embodiments of the present invention, the rotation of the worm 242 and the worm wheel 243 of the transmission mechanism 240 may be restricted, and the rotation of the first movable wheel group 250 and the second movable wheel group 260 may be restricted.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
