[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3The utility model provides a technical solution: an auxiliary lifting platform with a locking and limiting structure, comprising a mounting base 1, a lifting assembly 2 and a platform body 3, wherein a caster 101 is mounted on the bottom of the mounting base 1, the mounting base 1 is connected to the platform body 3 via the lifting assembly 2, a plug-in slot 4 is provided inside the platform body 3, and a plug-in board 401 is plugged into the plug-in slot 4;

[0023] Pulling blocks 402 are welded on both sides of the plug board 401, and a first magnetic block 403 is installed inside the pulling block 402, and a second magnetic block 404 is provided on one side of the first magnetic block 403. A return spring 405 is installed inside the plug board 401, and the bottom of the return spring 405 is connected to a limiting block 406, and one side of the limiting block 406 is plugged into the limiting groove 407 on the adjacent side. An air cavity 5 is opened inside the plug board 401, and a piston rod 503 is plugged into the air cavity 5. The magnetic properties of the first magnetic block 403 and the second magnetic block 404 are opposite on the adjacent sides, and the outer side of the second magnetic block 404 is connected to the platform body 3. An inflatable column 501 is installed on the top of the plug board 401, and one side of the inflatable column 501 is threadedly connected to the blocking cover 502. The end of the piston rod 503 away from the air cavity 5 is connected to the plug slot 4, and the piston rod 503 is symmetrically arranged inside the plug slot 4.

[0024] During specific implementation, in order to improve the safety of the auxiliary lifting platform when in use, before entering the interior of the platform body 3, the limit block 406 is first pulled upwards to disengage the limit block 406 from the limit groove 407 at the bottom, and then the plug-in plate 401 is moved toward the inflatable column 501 by pulling the block 402 until the limit block 406 is moved to the limit groove 407 on the side of the inflatable column 501. The limit block 406 will pop out under the action of the internal return spring 405, limiting the position of the plug-in plate 401. At this time, the worker can smoothly enter the interior of the platform body 3. After the worker enters the interior of the platform body 3, he pulls the limit block 406 upwards again, repeats the above operation, moves the plug-in plate 401 back to its original position, and the position of the plug-in plate 401 can be preliminarily locked and limited.

[0025] When there is a problem with the return spring 405 and the limit block 406 and they cannot be used normally, unscrew the blocking cover 502 on the side of the inflation column 501, and the gas can be replenished into the air cavity 5 through the inflation column 501. When the air pressure inside the air cavity 5 is saturated, the air pressure in the air cavity 5 is limited by the piston rod 503, which can keep the plug board 401 in the closed state. At the same time, the first magnetic block 403 on the side of the pulling block 402 and the second magnetic block 404 inside the platform body 3 will attract each other to achieve a locking and limiting effect in an emergency situation. The auxiliary lifting platform with a locking and limiting structure is provided with a double locking and limiting structure, which can be selected according to the usage scenario, and the operation methods of both are simple and easy, which can improve the safety of the auxiliary lifting platform when in use to a certain extent.

[0026] See Figure 3 and Figure 4 It can be seen that a mounting column 6 is welded inside the platform body 3, and the mounting column 6 is rotatably connected to the threaded adjustment rod 601 through a bearing seat. The bottom of the threaded adjustment rod 601 is connected to the output end of the drive motor 602 through a coupling, and the upper side of the drive motor 602 is connected to the platform body 3. The outer side of the threaded adjustment rod 601 is threadedly connected to the threaded connection block 603. A guide groove 605 is provided inside the mounting column 6, and one side of the threaded connection block 603 passes through the guide groove 605 and is welded to the placement frame 604. A drain outlet 606 is provided inside the placement frame 604.

[0027] During specific implementation, the staff needs to squat or bend down repeatedly to pick up the tools while working, which is time-consuming and laborious. Before using the tools, the staff first places the tools on the upper side of the placement frame 604 and starts the drive motor 602 installed with the platform body 3. The output end of the drive motor 602 drives the threaded adjustment rod 601 inside the mounting column 6 to rotate through the coupling, and under the guide limit action of the guide groove 605 on one side of the mounting column 6, the threaded adjustment rod 601 and the threaded connection block 603 act in thread, thereby driving the placement frame 604 and the tools inside the placement frame 604 to move to a height that is convenient for the staff to pick up and place. In order to avoid water accumulation inside the placement frame 604 when it is used outside, a drain outlet 606 for drainage is opened at the bottom of the placement frame 604. The auxiliary lifting platform with a locking limit structure can adjust the placement height of the work tools, so that the staff can easily and quickly obtain the tools.

[0028] To sum up, when using the auxiliary lifting platform with a locking limit structure, the auxiliary lifting platform is moved to the bottom of the work site by installing the casters 101 at the bottom of the base 1. Before the worker enters the interior of the platform body 3, he first pulls up the limit block 406 and moves the plug-in plate 401 toward the inflatable column 501 by pulling the block 402, so that the limit block 406 and the limit groove 407 on the side close to the inflatable column 501 are plugged into the limit under the action of the internal return spring 405. At this time, the worker can smoothly enter the interior of the platform body 3. After the worker enters the interior of the platform body 3, he pulls up the limit block 406 again and repeats the above operation to move the plug-in plate 401 back to its original position. At this time, the lifting component 2 is started. The lifting component 2 can push the platform body 3 to the work site with the cooperation of the inner components.
