Description

Technical Field

[0001] The utility model belongs to the technical field related to lifting platforms, and particularly relates to a lifting platform applicable to a tricycle. Background Technique

[0002] A lifting platform is a vertical transportation device widely used in industrial, commercial, and household fields. It can lift or lower goods or personnel through power sources such as electricity, hydraulics, or pneumatics to improve work efficiency and convenience. The types of lifting platforms include fixed, mobile, and guide rail types, which have the characteristics of simple structure, easy operation, safety and reliability, and are regularly inspected and maintained. However, there are still the following disadvantages in actual use:

[0003] When the lifting platform is working, its movement is basically through external structure traction, or it is forked by a forklift and then transported to a suitable position for use. During the transportation process, other equipment is required for cooperation and slow traction to the place, and the use is not flexible enough;

[0004] When the lifting platform is working, an additional auxiliary support structure is required to support on the ground to prevent the lifting platform from tipping over during work, causing potential safety hazards. During the auxiliary support process, it presses tightly against the ground, but during the transportation process, it needs to be folded and the position restricted before transportation. During the transportation process, it is likely to open due to shaking, affecting the transportation stability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lifting platform applicable to a tricycle, which solves the problems that the transportation process of the lifting platform is not flexible enough and the support structure of the lifting platform is likely to open due to shaking during transportation, affecting the transportation stability, by setting a bottom plate, a movable sleeve, a movable arm, and a limit sleeve.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a lifting platform applicable to a tricycle, which comprises a bottom plate, movable sleeves, movable arms and limiting sleeves. Both ends of the bottom plate are fixedly provided with movable sleeves. Two mutually parallel movable arms are movably connected in each movable sleeve. The two movable arms in the same movable sleeve are arranged in central symmetry. One end of the movable arm extending out of the limiting sleeve is rotatably connected with a rotating arm. The lower part of the outer side of each movable arm extending out of the movable sleeve is movably connected with a limiting sleeve. A T-shaped strip is fixedly arranged at the inner bottom of the limiting sleeve along the central line parallel to the length direction of the movable arm. The thickness of the T-shaped strip is equal to the height difference between the top of the rotating arm and the top of the movable arm. During operation, the lifting assembly is fixed on the bottom plate, and the movable arms are movably limited in the movable sleeves, so that when the electric tricycle transports the bottom plate, the movable arms can be retracted. The supporting area of the bottom plate is increased by the movable arms. After the movable arms are turned over, the position of the movable arms is changed by the limiting sleeves.

[0008] Furthermore, a lifting assembly is fixedly arranged on the top of the bottom plate. A lifting plate is fixedly arranged at the top of the lifting assembly. A guardrail is fixedly arranged at the top of the lifting plate. The bottom plate drives the lifting plate to lift through the lifting assembly, and the people and tools working on the lifting plate are protected by the guardrail.

[0009] Furthermore, mounting square steels are symmetrically and fixedly arranged on both sides of the bottom plate. A jack penetrating through the whole mounting square steel is vertically opened at the center of each mounting square steel. The bottom plate is mounted at a suitable position of the electric tricycle through the mounting square steels.

[0010] Furthermore, a partition plate is fixedly arranged between the two movable arms in the movable sleeve. Activity grooves are vertically and penetratingly opened at the bottoms of the movable sleeves on both sides of the partition plate along the direction parallel to the length direction. The two movable arms in the movable sleeve are separated by the partition plate through the movable sleeve.

[0011] Furthermore, a T-shaped groove is opened at the edge of the bottom of the movable arm close to the rotating arm. A plug rod is fixedly arranged at a position of the bottom of the movable arm symmetric to the center of the T-shaped groove. The plug rod is penetrated and inserted into the activity groove. The T-shaped strip is movably connected in the T-shaped groove. The movable arm is movably connected with the T-shaped strip through the T-shaped groove.

[0012] Furthermore, a screw rod is vertically and penetratingly threadedly connected at the center of the inside of the rotating arm. A rotating frame is fixedly arranged at the top end of the screw rod. A supporting disc is rotatably connected at the bottom end of the screw rod. By rotating the rotating frame of the rotating arm, the screw rod is driven to rotate, so that during operation, the supporting disc is pressed onto the ground and pressed tightly.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the lifting platform is not flexible enough during the transportation process by setting a bottom plate. After the electric tricycle transports the bottom plate and the components thereon to the appropriate position, the tricycle brakes first, and then the lifting components can work immediately. After the work is completed, the lifting components are started to descend. After the personnel and tools are evacuated from the lifting plate, the rotating arm is flipped, the limiting sleeve is pushed to the bottom end of the rotating arm, the rotating frame is rotated to press the limiting sleeve, and then the electric tricycle is driven away to complete the work. The working process is more flexible, and the positioning operation of the lifting platform is more convenient.

[0015] The utility model solves the problem that the supporting structure of the lifting platform is likely to be opened due to shaking during the transportation process and affect the transportation stability by setting a bottom plate, a movable sleeve, a movable arm and a limiting sleeve. After the operation is completed, the rotating frame is rotated in the reverse direction to drive the screw rod to rotate, and the supporting disc is lifted by the rotation of the screw rod to restore the free rotation of the rotating arm. The rotating arm is rotated until the supporting disc faces upward, and then the limiting sleeve is pushed to the outside of the rotating arm. After the position is restricted by the rotating frame, the rotating frame is rotated until the rotating frame is stuck on the limiting sleeve and pressed tightly, so that the supporting structure of the lifting platform is more firmly restricted during the transportation process, and the transportation stability is increased.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. Specific embodiment 1

[0026] Please refer to Figure 1-6 , the present invention is a lifting platform applicable to a tricycle, including a bottom plate 1, a movable sleeve 2, a movable arm 3 and a limit sleeve 4. Movable sleeves 2 are fixed at both ends of the bottom plate 1. The bottom plate 1 fixes the lifting structure on it so that it can be supported on a suitable electric tricycle (the electric tricycle is an existing public technology, so it is not drawn in the attached drawings). The movable arm 3 is movably connected in the movable sleeve 2 through the movable sleeve 2, so that the movable arm 3 can be retracted when not in use. Two mutually parallel movable arms 3 are movably connected in each movable sleeve 2. After the movable arm 3 is pulled out of the movable sleeve 2, the supported area of the bottom plate 1 is increased. The two movable arms 3 in the same movable sleeve 2 are arranged in central symmetry. One end of the movable arm 3 extending out of the limit sleeve 4 is rotatably connected with a rotating arm 301. The rotating arm 301 and the movable arm 3 are rotatably connected along the center of the mutually coincident surface. The movable arm 3 penetrates and threadedly connects a screw 302 through the rotating arm 301. A limit sleeve 4 is movably connected to the lower part of the outer side of each movable arm 3 extending out of the movable sleeve 2. After the limit sleeve 4 rotates the rotating arm 301, it moves to the bottom end surface of the rotating arm 301 at this time to limit the position of the rotating arm 301. A T-shaped strip 401 is fixed at the inner bottom of the limit sleeve 4 along the center line parallel to the length direction of the movable arm 3. The thickness of the T-shaped strip 401 is equal to the height difference between the top of the rotating arm 301 and the top of the movable arm 3, so that during work, the movable sleeve 2 can smoothly move to the bottom end surface of the rotated rotating arm 301.

[0027] Specifically, a lifting assembly 101 is fixed to the top of the bottom plate 1. The top of the lifting assembly 101 is fixed with a lifting plate 102, and a guardrail 5 is fixed to the top of the lifting plate 102. The bottom plate 1 drives the lifting plate 102 to lift through the lifting assembly 101, providing a walking space for the staff during work through the lifting plate 102, and providing protection for the staff on the lifting plate 102 through the guardrail 5.

[0028] Furthermore, mounting square steels 103 are symmetrically and fixedly arranged on both sides of the bottom plate 1. A jack hole 104 running through the entire mounting square steel 103 is vertically opened in the center of each mounting square steel 103. During installation, first observe the mounting position on the electric tricycle. If there is a suitable bolt mounting position on the electric tricycle and it corresponds to the position of the mounting square steel 103, place the bottom plate 1 on the electric tricycle, move the mounting square steel 103 until the jack hole 104 on the mounting square steel 103 aligns with the mounting position on the electric tricycle, then insert the mounting bolt into the jack hole 104 on the mounting square steel 103 and screw it into the mounting position on the electric tricycle. When there is no suitable mounting structure on the electric tricycle, directly place the bottom plate 1 in a suitable position on the electric tricycle, and then weld the mounting square steel 103 and the electric tricycle together by electric welding, so that the bottom plate 1 is mounted on the electric tricycle.

[0029] Furthermore, a partition 201 is fixed between the two movable arms 3 in the movable sleeve 2. Through slots 202 running through the bottom of the movable sleeve 2 parallel to the length direction are opened on both sides of the partition 201. The two movable arms 3 in the same movable sleeve 2 are separated by the partition 201 to limit the positions of the movable arms 3.

[0030] The operation process of this embodiment is as follows: During work, when the electric tricycle transports the bottom plate 1 and its components to a suitable position, the tricycle first brakes. After rotating the rotating frame 303 to release the limit sleeve 4, the limit sleeve 4 is pushed to separate from the rotating arm 301, and the rotating arm 301 is flipped. Immediately, the auxiliary support function of the bottom plate 1 can be carried out. When the movable arm 3 works, the supporting area of the bottom plate 1 is increased, and the working stability of the staff on the lifting plate 102 is increased. After the support is completed, when the staff climbs onto the lifting plate 102 and the working tools and the like are transported onto the lifting plate 102, the lifting assembly 101 is started to drive the lifting plate 102 to rise. After the lifting plate 102 rises to a suitable height, work starts. After work, the lifting assembly 101 is started to descend. After the personnel and tools are evacuated from the lifting plate 102, the rotating arm 301 is flipped, the limit sleeve 4 is pushed to the bottom end of the rotating arm 301, the rotating frame 303 is rotated to press the limit sleeve 4, and then the electric tricycle is driven away to complete the work. Specific Embodiment Two

[0031] Please refer to Figure 1 、 3, 4, 5, 6. On the basis of the first specific embodiment, a T-shaped groove 305 is provided at the bottom of the movable arm 3 near the edge of the rotating arm 301. A plug rod 306 is fixed at a position symmetric to the center of the T-shaped groove 305 at the bottom of the movable arm 3. The plug rod 306 is inserted through and connected in the movable groove 202. The T-shaped strip 401 is movably connected in the T-shaped groove 305. The movable arm 3 is movably connected to the T-shaped strip 401 through the T-shaped groove 305. By inserting the plug rod 306 into the movable groove 202 in the movable sleeve 2, the movement position of the movable arm 3 in the movable sleeve 2 is restricted, preventing the movable arm 3 from being completely withdrawn from the movable sleeve 2.

[0032] Specifically, a screw rod 302 is vertically and through-threadedly connected to the inner center of the rotating arm 301. A rotating frame 303 is fixed at the top end of the screw rod 302. The bottom end of the screw rod 302 is rotatably connected to a support disk 304. The movable arm 3 is connected to the rotating frame 303 and the support disk 304 through the screw rod 302. When the rotating arm 301 is flipped until the support disk 304 faces the ground, at this time, the rotating frame 303 is rotated to drive the screw rod 302 to rotate. Through the rotation of the screw rod 302, the support disk 304 is driven to descend to the ground and pressed against the ground, making the support of the bottom plate 1 more stable. When the operation is completed, the rotating frame 303 is rotated in the reverse direction to drive the screw rod 302 to rotate. Through the rotation of the screw rod 302, the support disk 304 is lifted upward to restore the free rotation of the rotating arm 301. The rotating arm 301 is rotated until the support disk 304 faces upward. Then, the limiting sleeve 4 is pushed to the outside of the rotating arm 301. Then, the rotating frame 303 is rotated until the rotating frame 303 is stuck to the limiting sleeve 4 and pressed tightly. After that, the tricycle can be started to transport the bottom plate 1 and the structures thereon to the next working position.

[0033] The operation process of this embodiment is as follows: When setting the support bottom plate 1, first push the limiting sleeve 4 away from the rotating arm 301. When the rotating arm 301 is flipped until the support disk 304 faces the ground, at this time, the rotating frame 303 is rotated to drive the screw rod 302 to rotate. Through the rotation of the screw rod 302, the support disk 304 is driven to descend to the ground and pressed against the ground, making the support of the bottom plate 1 more stable. When the operation is completed, the rotating frame 303 is rotated in the reverse direction to drive the screw rod 302 to rotate. Through the rotation of the screw rod 302, the support disk 304 is lifted upward to restore the free rotation of the rotating arm 301. The rotating arm 301 is rotated until the support disk 304 faces upward. Then, the limiting sleeve 4 is pushed to the outside of the rotating arm 301. After the position is restricted by the rotating frame 303, the rotating frame 303 is rotated until the rotating frame 303 is stuck to the limiting sleeve 4 and pressed tightly. After that, the tricycle can be started to transport the bottom plate 1 and the structures thereon to the next working position.
