Description
Technical Field
[0001] This utility model relates to the field of lifting platform technology, specifically a simplified lifting platform. Background Technology
[0002] In industrial production, overhead cranes are crucial lifting equipment with high usage frequency, making regular inspection and maintenance essential. Traditional overhead crane repair methods rely heavily on manual labor and simple tools, resulting in low efficiency and safety hazards when disassembling motors at heights. Therefore, there is an urgent need to design a simple lifting platform specifically for overhead crane repair to effectively handle motor disassembly and installation, improve repair efficiency, and ensure the safety of maintenance personnel.
[0003] Existing publicly available technical solution CN203255933U provides a repair crane lifting platform, including a square frame.

A first support rod is mounted between the second and third fixed rods, and a first handrail is mounted on top of the second and third fixed rods. A plurality of second support rods are mounted between the third and fourth fixed rods. A third support rod is mounted between the first and fourth fixed rods, and a second handrail is mounted on top of the first and fourth fixed rods. A square support plate is mounted at one-third of the length of each of the first, second, third, and fourth fixed rods. Two connecting blocks are longitudinally mounted at the bottom of the two long sides, each connecting block having a socket. This utility model has a simple structure and low cost, and can replace traditional expensive lifting platforms when used with a forklift.
[0004] However, when implementing existing technical solutions, forklifts are used to adjust the height of the overhead crane lifting platform. But forklifts cannot precisely adjust the vertical movement distance, which may lead to excessive adjustment range and affect maintenance efficiency. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] Given that existing technologies use forklifts to adjust the height of overhead crane lifting platforms, but forklifts cannot precisely adjust the vertical movement distance, this may result in excessive adjustment range, affecting maintenance efficiency.
[0007] To solve the above problems, this utility model provides the following technical solution:
[0008] A simple lifting platform includes a bracket, a first lead screw, a V-block, and an anti-slip pad. The first lead screw is threaded into the interior of the bracket; the V-block is externally bolted to the upper end of the first lead screw; the anti-slip pad is installed at the lower end of the bracket; the simple lifting platform further includes:
[0009] The system includes a lifting assembly, a limiting assembly, and an adjusting assembly; the lifting assembly is mounted on the surface of the first lead screw; the limiting assembly is mounted on the upper end of the bracket; and the adjusting assembly is mounted inside the V-block.
[0010] As a further embodiment of this utility model: the lifting assembly includes: a first handwheel and a stabilizing plate; the first handwheel is threadedly connected to the surface of a first lead screw; the stabilizing plate is slidably connected to the middle of the bracket.
[0011] As a further embodiment of this utility model: the lifting assembly further includes: a clamping plate; the clamping plate is fixed to the lower end of the first lead screw; the diameter of the clamping plate is larger than the diameter of the first lead screw.
[0012] As a further embodiment of this utility model: the limiting component includes: a fixing block and a first connecting block; the fixing block is welded to the upper end of the bracket; the first connecting block is connected to the inside of the fixing block through a rotating shaft.
[0013] As a further embodiment of this utility model: the limiting component further includes: a limiting post and a return spring; the limiting post is threadedly connected to the inside of the first connecting block; the return spring is connected to one side of the first connecting block.
[0014] As a further embodiment of this utility model: the adjustment component includes: a second lead screw and a second handwheel; the second lead screw is installed inside the V-block; the second handwheel is fixed to one end of the second lead screw.
[0015] As a further embodiment of this utility model, the adjusting assembly further includes a second connecting block and a third connecting block; the second connecting block is threadedly connected to the surface of the second lead screw; and the third connecting block is disposed on one side of the second connecting block.
[0016] As a further embodiment of this utility model: the adjustment assembly further includes: a first connecting plate, a second connecting plate, a first rotating shaft, and a second rotating shaft; the first connecting plate is rotatably connected to the V-block via the first rotating shaft, and the second connecting plate is rotatably connected to the upper end of the second connecting block via the second rotating shaft; the first connecting plate is slidably connected to the surface of the second connecting plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This utility model rotates the second handwheel, which drives the second lead screw to rotate, thereby driving the second connecting block and the third connecting block to move. The internal threads of the second connecting block and the third connecting block are opposite, so they move in opposite directions, thereby driving the first connecting plate and the second connecting plate to move. The second connecting plate is slidably connected to the inside of the first connecting plate, so it can automatically extend and retract during the movement, thereby realizing the adjustment of the opening and closing angle of the V-block, which can adapt to motors of different shapes.
[0019] 2. In this utility model, by rotating the first handwheel, the first lead screw is threadedly connected to the inside of the first handwheel. The first handwheel is fixed to the bracket by the bearing, thereby driving the first lead screw to rotate. Therefore, the first lead screw moves upward, thereby driving the V-block to move upward until it reaches the position of the motor.
[0020] 3. In this invention, when the first handwheel rotates, it contacts the limiting post, causing it to rotate and compress the return spring. When the first handwheel disengages from the limiting post, the force generated by the deformation of the return spring pushes the limiting post back to its original position. If the first handwheel rotates in the opposite direction at this time, the limiting post will not be able to rotate when it contacts the limiting post, thus limiting the first handwheel and preventing accidental contact by the operator. When it is necessary to lower the V-block, the limiting post is turned, and the limiting post is threadedly connected to the first connecting block, causing the limiting post to lower until its height is lower than the first handwheel. At this time, the first handwheel can rotate freely. Attached Figure Description

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.
[0031] Please see Figures 1-6 This embodiment provides a simple lifting platform, which includes a bracket 1, a first lead screw 2, a V-block 3, and an anti-slip pad 4. The first lead screw 2 is threaded into the inside of the bracket 1; the V-block 3 is connected to the upper end of the first lead screw 2 by external bolts; and the anti-slip pad 4 is installed at the lower end of the bracket 1.
[0032] The simplified lifting platform also includes a lifting assembly 5, a limiting assembly 6, and an adjusting assembly 7; the lifting assembly 5 is installed on the surface of the first lead screw 2; the limiting assembly 6 is installed on the upper end of the bracket 1; and the adjusting assembly 7 is installed inside the V-block 3.
[0033] Specifically, the lifting assembly 5 includes a first handwheel 501 and a stabilizing plate 503; the first handwheel 501 is threadedly connected to the surface of the first lead screw 2; the stabilizing plate 503 is slidably connected to the middle of the bracket 1.
[0034] Furthermore, the stabilizing plate 503 prevents the first lead screw 2 from deviating during the rising or falling process.
[0035] Specifically, the lifting assembly 5 also includes a clamping plate 502; the clamping plate 502 is fixed to the lower end of the first lead screw 2; the diameter of the clamping plate 502 is larger than the diameter of the first lead screw 2.
[0036] Furthermore, the card plate 502 ensures that the stabilizing plate 503 is always located on the surface of the first lead screw 2.
[0037] Specifically, the limiting component 6 includes a fixing block 602 and a first connecting block 603; the fixing block 602 is welded to the upper end of the bracket 1; the first connecting block 603 is connected to the inside of the fixing block 602 through a rotating shaft.
[0038] Furthermore, when the first lead screw 2 reverses and contacts the first connecting block 603, the fixing block 602 will press against the first connecting block 603 to prevent it from rotating.
[0039] Specifically, the limiting component 6 also includes a limiting post 601 and a return spring 604; the limiting post 601 is threadedly connected to the inside of the first connecting block 603; the return spring 604 is connected to one side of the first connecting block 603.
[0040] Furthermore, when the limit post 601 rotates, it will drive the first connecting block 603 to rotate, thereby compressing the reset spring 604.
[0041] In use, rotating the first handwheel 501 causes the first lead screw 2 to be threaded into the inside of the first handwheel 501. The first handwheel 501 is fixed to the bracket 1 by a bearing, which in turn drives the first lead screw 2 to rotate. As a result, the first lead screw 2 moves upward, which in turn drives the V-block 3 to move upward until it reaches the position of the motor. When the first handwheel 501 rotates, it contacts the limit post 601, causing it to rotate and compress the return spring 604. When the first handwheel 501 disengages from the limit post 601, the return spring 604 pushes the limit post 601 back to its original position due to the force generated by the deformation. If the first handwheel 501 rotates in the opposite direction, the limit post 601 will not be able to rotate when it contacts the limit post 601, thus limiting the first handwheel 501 and preventing accidental contact by the operator.
[0042] In summary, this utility model rotates the first handwheel 501, and the first lead screw 2 is threadedly connected to the inside of the first handwheel 501. The first handwheel 501 is fixed to the bracket 1 by a bearing, thereby driving the first lead screw 2 to rotate. Therefore, the first lead screw 2 moves upward, thereby driving the V-block 3 to move upward until it reaches the position of the motor. When the first handwheel 501 rotates, it contacts the limiting post 601, causing it to rotate and compressing the return spring 604. When the first handwheel 501 disengages from the limiting post 601, the force generated by the deformation of the return spring 604 pushes the limiting post 601 back to its original position. If the first handwheel 501 rotates in the opposite direction, the limiting post 601 will be unable to rotate when it contacts the limiting post 601, thus limiting the first handwheel 501 and preventing accidental contact by the operator. When it is necessary to lower the V-block 3, the limiting post 601 is screwed down. The limiting post 601 is threadedly connected to the first connecting block 603, causing the limiting post 601 to descend until its height is lower than that of the first handwheel 501. At this point, the first handwheel 501 can rotate freely.
[0043] Specifically, the adjustment assembly 7 includes a second lead screw 704 and a second handwheel 705; the second lead screw 704 is installed inside the V-block 3; the second handwheel 705 is fixed to one end of the second lead screw 704.
[0044] Furthermore, rotating the second handwheel 705 will cause the second lead screw 704 to rotate.
[0045] Specifically, the adjustment assembly 7 also includes a second connecting block 703 and a third connecting block 706; the second connecting block 703 is threadedly connected to the surface of the second lead screw 704; the third connecting block 706 is disposed on one side of the second connecting block 703.
[0046] Furthermore, the second connecting block 703 and the third connecting block 706 are both threaded to the surface of the second lead screw 704, and the internal threads of the second connecting block 703 and the third connecting block 706 are opposite.
[0047] Specifically, the adjustment assembly 7 also includes a first connecting plate 701, a second connecting plate 702, a first rotating shaft 707, and a second rotating shaft 708; the first connecting plate 701 is rotatably connected to the V-block 3 via the first rotating shaft 707, and the second connecting plate 702 is rotatably connected to the upper end of the second connecting block 703 via the second rotating shaft 708; the first connecting plate 701 is slidably connected to the surface of the second connecting plate 702.
[0048] Furthermore, the movement of the second connecting plate 702 causes the first connecting plate 701 to move. When the second connecting block 703 and the third connecting block 706 move, they cause the second connecting plate 702 and the first connecting plate 701 to rotate, thereby changing the opening and closing angle.
[0049] In use, rotating the second handwheel 705 drives the second lead screw 704 to rotate, which in turn drives the second connecting block 703 and the third connecting block 706 to move. The internal threads of the second connecting block 703 and the third connecting block 706 are opposite, so they move in opposite directions, which in turn drives the first connecting plate 701 and the second connecting plate 702 to move.
[0050] In summary, this utility model rotates the second handwheel 705, which drives the second lead screw 704 to rotate, thereby moving the second connecting block 703 and the third connecting block 706. The internal threads of the second connecting block 703 and the third connecting block 706 are opposite, so they move in opposite directions, thereby moving the first connecting plate 701 and the second connecting plate 702. The second connecting plate 702 is slidably connected to the inside of the first connecting plate 701, so it can automatically extend and retract during the movement, thereby realizing the adjustment of the opening and closing angle of the V-block 3 and adapting to motors of different shapes.
