Description

Technical Field

[0001] This utility model relates to the field of elevator shaft technology, specifically to a steel structure shaft component that is easy to assemble. Background Technology

[0002] An elevator shaft, or simply "shaft," is a vertical passageway in a building specifically for the vertical movement of elevators. It has a rectangular or square cross-section. Generally, one shaft is used by one elevator, but in special cases, two or more elevators can share a single shaft. A doorway is opened on each floor to install shaft doors. The shaft contains the elevator car and guide rails for the counterweight. The shaft pit contains the elevator car's buffer. The motor and transmission mechanisms are mostly located at the top of the shaft.

[0003] Chinese Patent Publication No. CN216974065U discloses an easily assembled steel structure shaft component, including a main frame and a central support frame. End strips are installed on the sides of the main frame, and auxiliary frames are installed on the sides of the end strips. Screws pass through the outer wall of the auxiliary frame, and a through hole is formed in the middle of the auxiliary frame. The central support frame is fixed to the side wall of the auxiliary frame by welding. An opening is formed inside the main frame, and a port is formed at the side end of the opening. A loading groove is formed in the middle of the main frame, and a carrier is placed at the inner end of the loading groove. A seat passage is formed on the side wall of the seat, and a passage opening is formed at the side end of the seat passage. This utility model allows the relative position of the end strips and auxiliary frames to be adjusted through mutual movement, enabling the structure of the device to be stretched for use, or conversely, to be retracted for a secure and compact combination. The design of multiple end strips and auxiliary frames allows for more connecting structures, resulting in higher safety performance during operation.

[0004] Existing elevator steel structure shafts are mostly welded from a single steel pipe. Therefore, when installing a steel structure shaft, it is necessary to first measure the height and then cut steel pipes of appropriate length for welding. This makes the welding and assembly of steel structure shafts time-consuming and labor-intensive. To address this, we propose a steel structure shaft component that is easy to assemble.

A first screw hole 7 is provided above the outer surface of the shaft riser 1, and a second screw hole 10 is provided below the outer surface of the shaft riser 1. A mounting bolt 11 passes through the second screw hole 10. A movable groove 2 is formed on the inner wall of the shaft riser 1, and an operating plate 3 passes through the movable groove 2. A limiting connecting post 8 is movably installed at the lower interior of the shaft riser 1. The shape and dimensions of the limiting connecting post 8 partially match the shape and dimensions of the interior of the shaft riser 1, and the operating plate 3 is fixedly connected to the limiting connecting post 8. The outer surface of the connecting post 8 is provided with mounting threaded holes 9 corresponding one-to-one with the second screw hole 10 and the first screw hole 7; the mounting bolt 11 is threadedly connected to the limiting connecting post 8 through the mounting threaded hole 9, and the limiting connecting post 8 is bolted to the shaft riser 1 through the mounting threaded hole 9, the second screw hole 10, and the mounting bolt 11; by setting the limiting connecting post 8 inside the shaft riser 1 and using bolts to bolt the limiting connecting post 8 to the two shaft risers 1 to be spliced, the splicing between the two steel structure shaft structural components can be completed, so that the two steel structures can be spliced ​​together.

[0020] Working Principle: When using this easily assembled steel shaft structure component, first place one shaft structure component on top of another, aligning their shaft risers 1. Then, push the operating plate 3 inside the movable groove 2 of the upper shaft structure component's shaft riser 1 to move the limiting connecting post 8 inside the shaft riser 1 downwards, inserting it into the shaft riser 1 of the lower shaft structure component. Next, insert the mounting bolt 11 into the second screw hole 10 and tighten it, connecting it to the limiting connecting post 8 through the mounting thread hole 9, thus fixing the shaft riser 1 and the limiting connecting post 8 together. Similarly, insert the bolt into the first screw hole 7 of the lower shaft structure component's shaft riser 1 and connect it to the limiting connecting post 8 through the threaded hole 9, thus fixing the shaft riser 1 and the limiting connecting post 8 together. 1. The two shaft structure components are fixed together, and then the connecting threaded rod 5 is inserted into the through hole 14 of the corresponding shaft horizontal pipe 4 on the upper and lower shaft structure components. Then, it is locked and fixed with nut 6. According to the height of the elevator shaft, the shaft structure components are spliced ​​upward to meet the height requirements.
