[0002] Unloading platforms are temporary operating platforms often set up at construction sites, generally used for material turnover. With the continuous emergence of high-rise buildings, the role of unloading platforms has become particularly prominent. Traditional construction unloading platforms cannot be lifted automatically as the construction progresses, which seriously affects the construction progress. Later, liftable unloading platforms appeared, which can rely on their own synchronous lifting equipment to lift and lower along the building as the construction progresses. The existing liftable unloading platforms are mainly composed of vertical guide rails, adjustable pull rods, protective fences, operating platforms, wall-mounted supports, lifting equipment, etc.

[0003] When materials are placed on the existing liftable unloading platform, workers need to enter the platform to carry them. Since the unloading platform is located at a high altitude, there is a certain risk, and the long distance back and forth affects the carrying efficiency. Utility Model Content

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] Example: Please refer to Figure 1-6 The liftable unloading platform comprises a wall-attached structure, a lifting mechanism and a material platform 3.

[0026] The wall-attached structure is fixedly connected to the building, and includes a pre-attached plate 1, a pre-embedded attachment bolt 11, and a wall-attached support 12. The pre-attached plate 1 is arranged horizontally, and the wall-attached support 12 is arranged vertically. The pre-attached plate 1 is attached to the floor plate and is fixedly connected to the floor plate through the pre-embedded attachment bolt 11. The wall-attached support 12 is attached to the wall and fixedly connected. The wall-attached support 12 is also fixedly connected to the end of the pre-attached plate 1. The wall-attached structure is provided with two groups that are parallel and at a certain distance. The wall-attached structure limits the positional relationship between the lifting mechanism and the material platform 3 and the building, so that the lifting mechanism and the material platform 3 can only move up and down within a fixed distance from the building.

[0027] The lifting mechanism is detachably connected to the wall-mounted structure. The lifting mechanism includes a guide rail 2, a lifting frame 5, a lifting cable 6 and a traction motor. The guide rail 2 is detachably connected to a wall-mounted support 12. The guide rail 2 can slide on the wall-mounted support 12. The wall-mounted support 12 is a common structure in this field, which is used to clamp the guide rail 2 after it goes up or down a certain distance to fix it. The specific structure of the wall-mounted support 12 is not repeated here. There are two groups of guide rails 2. The lifting frame 5 is fixedly connected to the two groups of guide rails 2. The lifting cable 6 is connected to the lifting frame 5 through a hook. The lifting cable 6 is wound on a winding wheel connected to the traction motor. The traction motor can be started to reel in or release the lifting cable 6, so that the lifting frame 5 drives the guide rail 2 to move up and down.

[0028] The material platform 3 is detachably connected to the lifting mechanism, and one end of the material platform 3 close to the wall-attached structure is detachably connected to the guide rail 2. The detachable connection method can be bolt connection, etc. The middle two sides of the material platform 3 are detachably connected to the guide rail 2 through the pull rod 31, that is, the pull rod 31 can be removed from the guide rail 2, and the existing technology can be used. The material platform 3 is fixedly connected with a railing 32 or a guardrail to prevent the material on the material platform 3 from falling. In this embodiment, it is a railing 32, and the left and right railings 32 are respectively fixedly connected with guide blocks 33. A trolley 4 is provided on the material platform 3, and a roller 43 is provided at the bottom of the trolley 4. Guide rods 41 slidably connected to the guide blocks 33 are provided on both sides of the trolley 4. The guide rods 41 are fixedly connected to the trolley 4, and a slide groove is provided on the guide block 33. The guide rod 41 and the slide groove are gap-matched, so that the guide rod 41 can slide on the guide block 33. One end of the guide rod 41 is aligned with the end of the trolley 4, and the other end extends to the outside of the material platform 3. The length of the guide rod 41 is longer than the length of the trolley 4. In this embodiment, the length of the guide rod 41 is at least twice the length of the trolley 4, so that when the trolley 4 itself just moves completely from the material platform 3 to the floor, the trolley 4 and the material platform 3 are still connected by at least its own length. The guide rod 41 is connected to the material platform 3 to prevent the trolley 4 from slipping off the material platform 3 after a short distance of movement. It needs to be re-aligned and installed, and the distance that the trolley 4 moves is also increased. A stopper 411 is provided at the end of the guide rod 41 located on the outside of the material platform 3. When the guide rod 41 continuously enters the slide slot until the stopper 411 abuts against the guide block 33, the trolley 4 cannot continue to move due to the abutment of the stopper 411, thereby preventing the trolley 4 from moving too far and slipping off the guide block 33 on the material platform 3. A handle 42 is fixedly connected to the end of the trolley 4 close to the wall-mounted structure to facilitate pushing and pulling the trolley 4. The trolley 4 is fixedly connected with a small railing or a small fence, which is a small fence in this embodiment. The function of the small railing or the small fence is consistent with that of the railing 32 or the fence, and a distinction is made in the naming for the convenience of distinction. The end of the guide rod 41 close to the wall-attached structure is fixedly connected with a second positioning block 412, and the end of the guide block 33 close to the wall-attached structure is fixedly connected with a first positioning block 331. The first positioning block 331 and the second positioning block 412 are respectively provided with positioning holes of the same size. When the trolley 4 is pushed back to the material table 3 for loading, the trolley 4 can be fixed to prevent movement by inserting the stick-shaped positioning rod into the positioning holes on the first positioning block 331 and the second positioning block 412.

[0029] The working principle of this embodiment: the liftable unloading platform provided in this embodiment limits the positional relationship between the lifting mechanism and the material platform 3 and the building body through the wall-attached structure, so that the lifting mechanism and the material platform 3 can only move up and down within a fixed distance from the building body. The traction motor can be started to reel in or release the lifting steel cable 6, so that the lifting frame 5 drives the guide rail 2 to move up and down, so that the material platform 3 can be moved to different floors. After the material platform 3 is moved to a fixed floor, the guide rail 2 can be clamped by the wall-attached support 12 to fix the guide rail 2 and the material platform 3. When the material is hung on the material platform 3 for placement, it is directly placed in the trolley 4, and then the positioning rod is pulled out, and the handle 42 is pulled. Under the action of the roller 43 and the guide rod 41, the trolley 4 moves from the material platform 3 to the floor, so that the worker can directly carry the material from the trolley 4 on the floor. Compared with entering the material platform 3 to carry out material transportation, on the one hand, the distance is shortened and the transportation efficiency is improved, and on the other hand, the risk of falling from a high altitude is reduced. After the transportation is completed, the trolley 4 is pushed back into the material platform 3 and the positioning rod is inserted to fix the trolley 4 for the next loading.
