Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, and in particular to a portable lifting platform for moving and installing wall panels. Background Technology

[0002] A lifting platform is a vertical transportation device used to lift or lower people, goods, or equipment between different heights. It typically consists of a platform or car, a drive system, guide rails, a control system, and safety devices. The drive system can be hydraulic, electric, or mechanical, transmitting power to move the platform vertically along the guide rails. Lifting platforms are widely used in many fields. In construction, they are used to transport building materials and workers to different floors; in factories and warehouses, they facilitate the loading, unloading, and storage of goods; and in shopping malls, hospitals, and other locations, they provide convenient vertical transportation.

[0003] When installing wall panels, a lift is also used to raise the workers to a suitable working height. In the existing technology, the standing platform of the lift is generally surrounded by only a fence, which can easily cause injury to the workers when subjected to external impact, resulting in a low safety factor. Therefore, this art proposes a portable lift for moving and installing wall panels to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable lifting platform for moving and installing wall panels, aiming to improve the problem that the standing platform of existing lifting platforms is generally surrounded by only a fence, which makes it easy for workers inside to be injured when subjected to external impacts, resulting in a low safety factor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable lifting platform for moving and installing wall panels, comprising a vehicle body, a lifting device installed on the top of the vehicle body, a base plate provided on the top of the lifting device, two fixed posts fixedly connected to the top of the base plate, two sliding rods fixedly connected to the outer side of the fixed posts, two sliders slidably connected to the outer side of the sliding rods, two springs sleeved on the outer side of the sliding rods, a connecting rod rotatably connected to one side of the sliders, a protective plate rotatably connected to one end of the four connecting rods, and an auxiliary boarding assembly provided on the top of the vehicle body for the user to easily board the top of the base plate.

[0006] Furthermore, the boarding assistance component includes a movable frame disposed on adjacent sides of the two fixed posts.

[0007] Furthermore, multiple fixed posts are fixedly connected to the inner side of the movable frame, and sliding posts are fixedly connected to both outer sides of the movable frame.

[0008] Furthermore, a groove is provided on one side of the fixed pile, and the outer side of the sliding column is slidably connected to the inner side of the groove.

[0009] Furthermore, two limiting blocks are rotatably connected to the outer side of the base plate, and the outer side of the limiting blocks fits against the outer side of the movable frame.

[0010] Furthermore, one end of the spring is fixedly connected to the outside of the fixed post, and the other end of the spring is fixedly connected to the outside of the slider.

[0011] Furthermore, the outer side of the slider is slidably connected to the outer side of the fixed pile.

[0012] Furthermore, the top of the lifting device is rotatably connected to the bottom of the base plate.

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

[0014] 1. In this utility model, after the protective plate is subjected to an impact force, the two connecting rods rotate and push the two sliders to slide along the outside of the sliding rods, thereby squeezing the two springs. At this time, the springs can absorb most of the impact force and buffer and remove the impact force, thus protecting the workers on the top of the base plate from being injured by too much impact force.

[0015] 2. In this utility model, by rotating the two limiting blocks and tilting the movable frame at a certain angle, the movable frame can be pulled down so that one end of the movable frame contacts the ground. In this way, the workers can step on the fixed posts to climb to the top of the base plate. Then, the movable frame can be retracted, and the limiting blocks can be rotated vertically upward to limit the movable frame. In this way, a complete fence can be formed with the two fixed posts to prevent workers from falling from the top of the base plate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a portable lifting platform for moving and installing wall panels, comprising a vehicle body 1, a lifting device 2 mounted on the top of the vehicle body 1, the lifting device 2 being a scissor-type connecting rod mechanism, a commonly used lifting mechanism in the prior art, a base plate 3 provided on the top of the lifting device 2, two fixed posts 4 fixedly connected to the top of the base plate 3, two sliding rods 5 fixedly connected to the outer side of the fixed posts 4, two sliders 7 slidably connected to the outer side of the sliding rods 5, two springs 6 sleeved on the outer side of the sliding rods 5, and a connecting rod 8 rotatably connected to one side of the sliders 7, with one end of the four connecting rods 8 rotating. The vehicle body 1 is equipped with a protective plate 9 and an auxiliary boarding assembly on its top. The auxiliary boarding assembly is used to facilitate users to climb onto the top of the base plate 3. When the fixed pile 4 is hit or collided by an external object, it will first contact the protective plate 9. After the protective plate 9 is hit, the two connecting rods 8 rotate and push the two sliders 7 to slide along the outside of the sliding rod 5, which in turn compresses the two springs 6. At this time, the springs 6 can absorb most of the impact force and can buffer and remove the impact force, thus protecting the staff on the top of the base plate 3 and preventing them from being injured by too much impact force.

[0024] Reference Figures 2-4The boarding assistance component includes a movable frame 11, which is positioned on the adjacent sides of two fixed posts 4. Multiple fixed posts 12 are fixedly connected to the inner side of the movable frame 11, and sliding posts 13 are fixedly connected to both outer sides of the movable frame 11. A sliding groove 10 is provided on one side of each fixed post 4, and the outer side of the sliding post 13 is slidably connected to the inner side of the sliding groove 10. Two limiting blocks 14 are rotatably connected to the outer side of the base plate 3, and the outer side of the limiting blocks 14 fits against the outer side of the movable frame 11. One end of a spring 6 is fixedly connected to the outer side of the fixed post 4, and the other end of the spring 6 is fixedly connected to the outer side of the slider 7. The outer side of the slider 7 is slidably connected to the outer side of the fixed pile 4. The top of the lifting device 2 is rotatably connected to the bottom of the base plate 3. After rotating the two limiting blocks 14, the movable frame 11 can be tilted at a certain angle and then pulled downward so that one end of the movable frame 11 contacts the ground. In this way, the workers can step on the fixed pile 12 to climb to the top of the base plate 3. Then the movable frame 11 can be retracted, and the limiting block 14 can be rotated vertically upward to limit the movable frame 11. The outer side of the limiting block 14 has a large coefficient of friction with the outer side of the base plate 3, making it easy to be in a vertical state.

[0025] Working principle: First, after rotating the two limiting blocks 14, the movable frame 11 is tilted at a certain angle, and then the movable frame 11 can be pulled downward so that one end of the movable frame 11 contacts the ground. In this way, the worker can step on the fixed post 12 to climb onto the top of the base plate 3. Then, the movable frame 11 is retracted, and the limiting blocks 14 are rotated vertically upward to limit the movable frame 11. The outer side of the limiting block 14 has a large coefficient of friction with the outer side of the base plate 3, making it easy to maintain a vertical position. In addition, when the fixed post 4 is hit or collided by an external object, it will first contact the protective plate 9. After the protective plate 9 is hit, the two connecting rods 8 rotate and push the two sliders 7 to slide along the outside of the sliding rod 5, which in turn compresses the two springs 6. At this time, the springs 6 can absorb most of the impact force and buffer and dissipate the impact force, thus protecting the workers on the top of the base plate 3 from being injured by too much impact force.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
