Embodiment 1

[0032] see Figure 1 to Figure 3 As shown, Embodiment 1 of the present invention provides an anti-displacement trigger device, which includes a touch mechanism and an electromagnetic holding mechanism. The touch mechanism includes two trigger plates 101, and an energy storage assembly is arranged between the two trigger plates 101. The energy component can release the elastic potential energy to push the two trigger plates 101 to move back; the electromagnetic holding mechanism is used to keep the energy storage component to maintain the elastic potential energy.

[0033] When in use, the anti-displacement trigger device is installed on the elevator speed governor. When the elevator safety system detects the moment when the elevator moves unexpectedly, the electromagnetic holding mechanism is separated from the energy storage component, and the elastic potential energy of the energy storage component is released. , and push the two trigger plates to move back, so that the cent...

Embodiment 2

[0051] In the second embodiment of the present invention, the anti-displacement trigger device provided by the first embodiment is added to the existing XS3 type elevator speed limiter to form a new elevator speed limiter, so that the braking of the safety gear is more efficient. Safety. The principles and specific structures of the involved centrifugal plate 112 , governor housing 114 , safety gear and other components are all in the prior art, and will not be described in detail here.

[0052] see Figure 4 As shown, the second embodiment provides an elevator speed governor, including a centrifugal plate 112, a speed governor housing 114, and the anti-displacement trigger device provided by the first embodiment. The touch piece is installed on the centrifugal plate; the anti-displacement trigger The device is installed on the housing of the speed governor, and is used to hit the touch piece to rotate the centrifugal plate, so that the speed governor of the elevator is trigg...

Abstract

The invention relates to the technical field of elevator safety devices, particularly to a motion prevention trigger device and an elevator speed limiter. The motion prevention trigger device comprises a touch mechanism and an electromagnetic maintaining mechanism, wherein the touch mechanism comprises two trigger boards; an energy storage assembly is arranged between the two trigger boards; the energy storage assembly can release elastic potential energy to push the two trigger boards to move in the reverse direction; and the electromagnetic maintaining mechanism is used for enabling the energy storage assembly to maintain elastic potential energy. The elevator speed limiter comprises a centrifugal board, a speed limiter shell and the motion prevention trigger device. The motion prevention trigger device has the characteristics that an elevator can be prevented from accidentally moving, and the safety coefficient of utilization of the elevator is strengthened.

Description

technical field [0001] The invention relates to the technical field of elevator safety devices, in particular to an anti-displacement trigger device and an elevator speed governor. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take advantage of people or carry goods. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. Modern elevators are mainly composed of traction machines (winches), guide rails, counterweight devices, safety devices (such as speed governors, safety gears an...
