Description

Technical Field

[0001] The utility model belongs to the field of elevator shaft reinforcement, in particular to a pit reinforcement device. Background Art

[0002] Home elevators are becoming increasingly common. In building-within-a-building configurations, the presence of a passenger space beneath the elevator necessitates the installation of a counterweight safety clamp. Both the counterweight and car safety clamps are crucial safety devices for ensuring safe operation. The counterweight safety clamp is a safety brake device located on the elevator's counterweight. It prevents the counterweight from rapidly falling in the event of a wire rope break, protecting the passenger space below. In the event of a wire rope break, the counterweight rapidly falls and strikes the floor. When the speed reaches 115% of the rated speed, the counterweight safety clamp is triggered, clamping the counterweight to stop its descent and protecting the floor below from being pierced by the counterweight. The car safety clamp is primarily a safety device installed beneath the car. When the speed below the car reaches 115% of the rated speed, the safety clamp's clamp, driven by the speed limiter, locks the car's running track, preventing the elevator from descending further and protecting passengers. Unlike the counterweight safety clamp, the car safety clamp is triggered based on the car's operating height and only triggers under abnormal conditions such as overspeed or overload. In short, both the counterweight safety clamp and the car safety clamp are essential safety features in elevator design. Their function is to monitor and protect the safety of passengers at all times during elevator operation. The installation of the counterweight safety clamp is not only expensive, but also requires space in the hoistway, reducing the usable area of ​​the car.

[0003] In summary, the present invention provides a pit reinforcement device to solve the above problems. Utility Model Content

[0012] 1. The utility model fixes the reinforcing channel steel at the floor beam position and fixes the abutment block to the floor beam with expansion bolts. Even if the wire rope breaks and the counterweight falls to the ground, the reinforcing channel steel can still protect the floor slab from being penetrated and threatening the personal safety of the residents downstairs.
