Description
Technical Field
[0001] The utility model relates to the technical field of lifting devices for construction, in particular to a lifting device for building construction. Background Art
[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place of construction is called "construction site" or "construction site", also called construction site. In the process of house construction, due to the gradual increase of the floor level of the house, it is not convenient to deliver materials, so there will be special lifting devices for construction.
[0003] At present, electric scaffolding is often used on construction sites to lift building materials. Generally speaking, people stand in the middle of the lifting frame, and the building materials are placed on both sides, or only the building materials are lifted, the building materials are placed in the middle area, and the objects and people are lifted by the winch and pulley group, but this method has some problems:
[0004] 1. When building materials (such as bagged cement and stone, etc.) are placed on both sides of the lifting frame, it is not easy to know the force on both sides of the lifting frame. It is usually difficult to ensure that the building materials are evenly placed on both sides of the lifting frame, which easily leads to one end of the lifting frame being light and the other end being heavy, resulting in poor stability of the items during the lifting process;
[0005] 2. Because the common electric scaffolding currently has its own walking wheels, there is a certain height difference between the lifting frame and the ground. When transporting construction materials to the lifting frame, it is often easier to carry and unload at the edge of the lifting frame, while the middle of the lifting frame requires people to step on the lifting frame and walk to the middle of the lifting frame to unload. During the transportation process, people may accidentally step on empty space, which poses a safety hazard and is inconvenient to transport. Utility Model Content

The supporting frame is provided with walking wheels and corresponding brake pads to facilitate the movement of the electric scaffold 1.
[0027] Two loading plates 7 are provided and are arranged relatively above both sides of the lifting frame 9. The corners of the loading plate 7 are slidably connected with columns 12, and the bottom of the columns 12 is fixed to the lifting frame 9, so that the loading plate 7 can move up and down relative to the lifting frame 9. The outer sleeve of the column 12 is provided with a spring 11, and the two ends of the spring 11 are respectively connected to the lifting frame 9 and the loading plate 7. The outer surfaces of the columns 12 on both sides are provided with scale lines 8 inwardly. By placing building materials on the loading plates 7 on both sides, the loading plates 7 are subjected to pressure drop and the springs 11 are compressed. By observing the descending distance of the two loading plates 7, the weight on the two loading plates 7 can be judged. Then, when carrying building materials onto the loading plates 7, the position of the loading plates 7 on the scale lines 8 is observed, and the weight difference on the loading plates 7 on both sides can be intuitively observed. According to the weight difference between the two loading plates 7, the building materials are carried to the corresponding loading plates 7 to keep the weight of the loading plates 7 on both sides relatively balanced, so that the lifting frame 9 is more stable when lifting building materials.
[0028] A cavity is provided on the upper surface of the loading board 7, which runs through the upper and lower parts. Rollers 10 in a linear array are rotatably connected in the cavity. By means of the rollers 10, the building materials can be placed on the edge of the loading board 7, freeing the hands, and then the lifting frame 9 can be walked to pull the building materials to the middle position of the loading board 7, which is convenient for transportation and safe.

[0030] Two fences 5 are arranged above the loading board 7. Through the arranged fences 5, the fences 5 can play a role of longitudinal limiting the construction materials on the loading board 7. One end of the fence 5 is rotatably connected to a rotating shaft 6, and the bottom of the rotating shaft 6 is fixed on the loading board 7. The other end of the fence 5 is slidably connected to a positioning rod 3, and a positioning hole matched with the positioning rod 3 is opened at the corresponding position of the loading board 7, so that the positioning rod 3 can be inserted into the positioning hole to realize the positioning of the fence 5. The two fences 5 are correspondingly distributed on both sides of the loading board 7 and play a role of longitudinal limiting the construction materials on the loading board 7. Through the arranged rotating shaft 6, positioning rod 3 and positioning hole, the rotating shaft 6 can be used as the rotation center to release the limit on the movable end of the fence 5, and the fence 5 can be swung to one side, so as to facilitate the transportation of construction materials to the loading board 7.

As the building materials on the loading board 7 increase, observe the position of the loading board 7 on the scale line 8, and you can intuitively observe the weight on the loading boards 7 on both sides, and according to the weight difference between the two loading boards 7, carry the building materials to the corresponding loading board 7 to keep the loading boards on both sides The weight of 7 is relatively balanced. After the transportation is completed, the multi-section pressure plate 4 is covered on the building materials, and the rope 2 is tightened and fixed to the connecting rod 13 on the other side of the loading plate 7. The multi-section pressure plate 4 can better fit the building materials and apply pressure, so that the multi-section pressure plate 4 can press the building materials on the loading plate 7 and play a role in lateral limitation.
