Abstract

The invention discloses an elevator baking device with a trigger mechanism. The trigger mechanism comprises a trigger part. The trigger part comprises a trigger mechanism hitting plate, a pair of springs, a pair of guide rods, a pair of spring seats, a pair of piston assemblies, an electromagnet actuating rod fixedly connected with the trigger mechanism hitting plate, and an electromagnet capableof driving the electromagnet actuating rod. The trigger mechanism hitting plate is arranged in a shaftway. The spring seats are fixedly mounted on the inner side of the trigger mechanism hitting plate, the guide rods are sleeved with the spring seats, the left ends of the guide rods are fixedly connected to fixing seats of the spring seats, the piston assemblies are connected to the right ends ofthe guide rods, and the piston assemblies are movably arranged in guide holes of fixing parts. Due to the adoption of the structure, the elevator braking device is good in balance performance, stablein running and good in guiding performance, dust in the guide holes can be cleared away, and therefore the service life of the elevator braking device with the trigger mechanism is prolonged.

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] With the development of the economic level, people have more and more requirements for buildings, making barrier-free buildings 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] Chinese patent CN201310717906.0 discloses an elevator stop device with a trigger mechanism, including a brake mechanism and a trigger mechanism; the brake mechanism includes a clamp body and a f...
