Description

Technical Field

[0002] The elevator system in building construction is an important tool to improve construction efficiency. It undertakes important transportation tasks in the process of high-rise building construction. In recent years, with the acceleration of urbanization, the number of high-rise buildings has continued to increase, and the demand for construction elevators has also increased. Compared with permanent elevators, construction elevators have slow running speeds and small loading capacity. Therefore, the present invention is based on the idea of ​​pre-installation of permanent elevators. The permanent elevator is installed during the construction of the construction elevator shaft. As the elevator shaft is constructed upward layer by layer, the machine room is jumped every 4 to 5 floors. After each jump, the connecting wire rope between the machine room and the car is installed and can be used normally. The use of a jump elevator can greatly improve the vertical transportation efficiency of super-high-rise construction.

[0003] In the prior art, in order to solve the problem of insufficient stability of construction elevators during use, complex suspension and support structures are usually used to improve stability. In addition, some designs use structural methods to strengthen the connection between the elevator machine room and the elevator car. These solutions can enhance the stability of the elevator system to a certain extent, but they also increase the complexity and cost of the system.

[0004] Although the existing elevator system can provide basic vertical transportation functions, in the construction of high-rise buildings, the elevator room and the car are prone to shaking during movement, especially in strong winds or overload conditions, and the elevator system often collides with the elevator shaft wall, posing a safety hazard. These problems show that conventional means in the existing technology have limited effects on improving the stability of the elevator system and are difficult to meet the high requirements in the actual construction process.

The elevator machine room 3 is connected to the lifting assembly 2, and the elevator machine room 3 and the elevator car 4 are connected through a traction machine 31. The lifting assembly 2 drives the elevator machine room 3 to slide along the height direction of the elevator shaft 1, and further drives the elevator car 4 to move. A person installs a guide rail 51 in the elevator shaft 1, and a mounting block 512 of the guide rail 51 is plugged into the mounting groove 12 of the elevator shaft 1. Multiple guide rails 51 are connected through plug-in grooves 514 and plug-in blocks 513, and rollers 52 slide along the guide rail 51;

[0071] The motor 73 drives the screw rod 72 to rotate, driving the sliding rod 61 to slide along the height direction of the elevator shaft 1, driving the ball 63 to contact the side wall of the second wedge block 62, and pushing the second wedge block 62 to abut against the side wall of the first wedge groove 5311, thereby realizing the locking and fixation of the fixed part 531 and the movable part 532. When the construction is completed, the screw rod 72 rotates in the opposite direction, driving the sliding rod 61 to slide in the opposite direction, so that the second wedge block 62 is disengaged from the side wall of the second wedge groove 5322, so that the movable part 532 can slide along the groove wall of the first wedge groove 5311, further disengaging the movable part 532 from the fixed part 531, and fixing the elevator machine room 3 to the elevator shaft 1.
