Embodiment Construction

[0012] The clamping mechanism 13 of the present invention is installed in the guide rail groove 15 at the bottom of each floor of the building, and two pairs are installed on each floor, arranged symmetrically. Composed of rubber 5, one end of the clamping mechanism 13 is connected with the compression spring 6. When the elevator breaks down, the clamping mechanism 13 is ejected by the compression spring 6, and moves along the guide rail groove 15 to the side of the elevator car 4, directly clamping the falling car. The elevator car 4 makes the elevator car 4 brake in time, and the shock-absorbing steel plate 10 can buffer the huge instantaneous impact force produced by the falling elevator car 4, and prevent the clamping mechanism 13 from directly acting on the elevator shaft wall 11. damage, the shock-absorbing rubber 5 can reduce the damage and impact discomfort caused by the instantaneous braking of the elevator personnel; the electromagnetic mechanism 7 is composed of a co...

Abstract

The invention discloses a novel elevator car braking device, and in particular, relates to the field of mechanisms and electric engineering. The elevator car braking device comprises a tension sensor mounted at the top of an elevator car and connected with a load cable, clamp mechanisms mounted at the bottoms of all floors of a building, guide rails and guide rail grooves, electromagnetic mechanisms and compression springs positioned at control ends of the clamp mechanisms, and distance sensors, hand brakes and other auxiliary devices between the clamp mechanisms and the electromagnetic mechanisms. The power failure of the electromagnetic mechanisms is controlled through an automatic or manual mode, so that two pairs of the clamp mechanisms are ejected out to stop the falling of the elevator car. The elevator car braking device has important practical significance no matter in the industrial reform or in the social safety, and is worthy of being applied and promoted.

Description

technical field [0001] The invention relates to an elevator car braking device used in buildings, which belongs to the field of machinery and electricity. Background technique [0002] With the development of society and the advancement of science and technology, more and more buildings use elevators as the main means of transportation. The use of elevators provides a lot of convenience for people's life and production. From the initial unsafe elevators to the current intelligent control elevators, the safe operation of elevators has always attracted much attention. The history of elevator development is also a history of blood and tears with frequent accidents. Although the current elevators have achieved relatively safe operation, due to various reasons, elevator accidents are still happening every year. Especially in high-rise buildings, if the protective device of the elevator fails, the consequences of the elevator falling will be disastrous. Therefore, [STD1] is in u...
