Embodiment Construction

[0043] The preferred implementation of the present invention is a one-way mechanism similar to the safety gear of an elevator; taking the car (or counterweight) down-moving braking device as an example, when the elevator car (or counterweight) goes down, the braking mechanism acts It can produce a force that hinders the elevator car (or counterweight) from going down. When the elevator car (or counterweight) goes up, the force of the braking mechanism will decrease or disappear; because the elevator car (or counterweight) has already In the abnormal position of the overriding inspection operation, the maintenance personnel must first move the car (or counterweight) up to the normal position in the process of restoring the use of the elevator. If the force on the brake mechanism still exists, the up operation will become difficult; therefore, the braking mechanism should preferably act in one direction, as long as the car (or counterweight) can be stopped at a certain decelerati...

Abstract

The invention discloses an elevator brake device with a trigger mechanism. The elevator brake device comprises a brake mechanism and the trigger mechanism. The brake mechanism comprises a caliper and a fixed part; the caliper can move up and down relative to the fixed part. When an elevator is under maintenance, the trigger mechanism extends out; when a car of the elevator or its counterweight descends or ascends to a maintenance allowed limit position or exceeds the same, the trigger mechanism triggers the brake mechanism to move, and the caliper of the brake mechanism engages in friction with the fixed part so that the car or the counterweight slows down to descend or ascend and stops; after moving, the brake mechanism brakes the car or the counterweight in the height range, and the trigger mechanism keeps the caliper of the brake mechanism and the fixed part thereof attached; when the elevator runs normally, the trigger mechanism is collected, and the elevator runs normally in the travel range. By limiting the area which the car or the counterweight can reach during maintenance, staff on the top of the car or in a bottom pit can be provided with sufficient safety space when the elevator is under maintenance.

Description

technical field [0001] The invention relates to an elevator accessory, in particular to an elevator stopping device with a trigger mechanism. Background technique [0002] Barrier-free buildings are the trend of future buildings, and the need to install elevators in old multi-storey buildings has also been put on the agenda. For the elevators in this part of the building, it is usually necessary to install a shaft, but due to restrictions such as building standards, the installed shaft cannot meet the relevant requirements of GB7588-2003 "Safety Code for Elevator Manufacturing and Installation", especially during maintenance and operation. Operator escape space requirements. [0003] The structure of the elevator is as figure 1 As shown, the car 1 runs up and down along the car guide rail 6, and the counterweight 4 runs up and down along the counterweight guide rail 7; the suspension device 5 connects the car 1 and the counterweight 4; The weight 4 runs in the hoistway 10...
