Detailed Description

In order to make the features and advantages of the present utility model more comprehensible, the following description should be taken in conjunction with the accompanying drawings.

Embodiment one:

a lifting elevator with anti-pinch protection, as shown in fig. 1 and 2, comprises a car 1, two car doors 2 and two hoistway doors 3. The two car doors 2 are provided with a first light curtain emitter 4 and a first light curtain receiver 5 on one side close to the hoistway door 3, respectively, and the first light curtain emitter 4 and the first light curtain receiver 5 are matched for detecting whether foreign matters exist between the two.

The opposite side walls of the two car doors 2 are provided with grooves 6, the bottoms of the grooves 6 are fixedly provided with compression springs 7, the free ends of the compression springs 7 are fixedly provided with foam 8 with buffering effect, and the compression springs 7 are in a loose state, and the heights of the compression springs 7 and the foam 8 are greater than the depth of the grooves 6. When the two car doors 2 are closed, the foam 8 is fully compressed within the groove 6.

Two opposite side walls at the entrance of the car 1 are vertically provided with strip grooves correspondingly, the strip grooves are positioned on one side close to the car door 2, and a second light curtain emitter 9 and a second light curtain receiver 10 which are matched with each other are respectively arranged in the two strip grooves.

The first light curtain emitter 4 and the first light curtain receiver 5, and the second light curtain emitter 9 and the second light curtain receiver 10 are electrically connected with a control system of the elevator, when the elevator door is about to be closed, the first light curtain emitter 4 emits light curtains to the first light curtain receiver 5, meanwhile, the second light curtain emitter 9 emits light curtains to the second light curtain receiver 10, when any one of the two groups of light curtains is blocked, the existence of foreign matters between the two car doors 2 is indicated, the light curtain receiver feeds back the information to the control system, and at the moment, the car doors 2 are opened towards two sides under the control of the control system; only when the first light curtain receiver 5 and the second light curtain receiver 10 can receive the normal signal at the same time, it is indicated that no foreign matter exists between the two car doors 2, and the car doors 2 can be normally closed.
