Problems solved by technology

[0003] In the current production of elevators, rope holding devices or safety gears are usually used to brake after accidental movement. However, due to the concentrated force of the rope holding device, due to problems such as aging of the traction rope and internal corrosion of the device, the rope will be pulled after the rope is held. The rope is broken, and a secondary accident occurs. The use of the safety gear in the braking of the elevator is easy to cause injuries to the passengers inside due to the excessive braking force and the rapid change of the elevator speed.

Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples. Based on the examples of the present invention, all other examples obtained by those of ordinary skill in the art without creative efforts belong to the protection of the present invention. range.

[0037] A rapid braking device for preventing accidental movement of an elevator, such as figure 1 and figure 2 As shown, it includes a housing 401, a mounting plate 402, a brake block 1 403, a brake block 2 404, a brake block 3 406, a sensor 408 and a brake wheel 410, wherein the housing 401 is fixedly installed on the elevator car On the car 3, it is passed by the guide rail 2 of the elevator. The brake wheel 410 is fixedly installed on the car 3, and it is located on the left and right sides of the guide rail 2. When the elevator moves normally, the brake wheel 410 and the guide rail 2 produce rolling friction. When the elevator moves unexpectedly,...

Abstract

The invention relates to the field of elevator braking, in particular to a rapid braking device for preventing accidental movement of an elevator, which includes a housing, a mounting plate, a brake block 1, a brake block 2, a brake block 3, a sensor and a brake wheel, Wherein, the housing is fixedly installed on the elevator car, which is passed by the elevator guide rail, and the brake wheel is fixedly installed on the car, which is located on the left and right sides of the guide rail. When the elevator moves normally, the brake wheel and the guide rail Rolling friction is generated. When the elevator moves unexpectedly, the brake wheel stops, and the rolling friction becomes sliding friction. The installation plate is fixedly installed on the car, which is located on the right side of the guide rail, and the inside of the installation plate is equipped with an electromagnetic Iron, the power on and off of the electromagnet is controlled by the output signal of the sensor. The brake block 1, brake block 2 and brake block 3 are respectively located on the upper left and right sides of the guide rail. When the elevator moves unexpectedly, the electromagnet When power is off, the brake block is driven by spring preload to brake the elevator from three sides of the guide rail.

Description

technical field [0001] The invention specifically relates to the technical field of elevator braking, in particular to a quick braking device for preventing accidental movement of an elevator. Background technique [0002] In social life, elevator falling accidents have occurred many times, causing serious casualties. In these accidents, most of them are due to the simultaneous existence of elevator braking devices after accidents (elevator traction rope breakage, traction machine failure, etc.) It can be seen that a reliable elevator braking device plays a vital role in the safety of the elevator. [0003] In the current production of elevators, rope holding devices or safety gears are usually used to brake after accidental movement. However, due to the concentrated force of the rope holding device, due to problems such as aging of the traction rope and internal corrosion of the device, the rope will be pulled after the rope is held. The rope breaks, and a secondary accide...
