Abstract
The utility model discloses a simple and easy device of hauler stopper gap monitoring that declutches mainly includes stopper, lifting hook, traction sheave, detects the piece, and the left and right sides symmetry of traction sheave is provided with the lifting hook, installs the stopper in the left and right sides symmetry of traction sheave simultaneously, it installs in stopper gap A to detect the piece. The utility model has the advantages that: the magnitude of brake release clearance tension pressure of the brake during the operation of the elevator is monitored in real time, so that the brake release effect can be controlled and adjusted.
Description
Technical Field
The utility model relates to an elevator technical field, concretely relates to simple and easy device of hauler stopper gap monitoring that declutches.
Background
With the rapid development of the modern building industry and the wide use of elevators, higher requirements are also put forward on the safety performance of elevator products. The safety performance of the traction machine as a power device of the elevator is particularly important. In recent years, energy-saving, environment-friendly and space-saving permanent magnet synchronous machine room-less elevators have been more and more favored by customers, but because the machine room-less elevators are compact in design and small in space and are not as convenient to operate as machine room elevators, the application of the electric brake release device of the elevator can just solve the problem. The elevator brake release power supply device is started by a starting button in the control cabinet under the condition of power failure of an external power grid, only enough voltage for enabling the brake to be opened is provided, the characteristic of self-generation of the permanent magnet synchronous motor is utilized, the input end of the motor is in short circuit, and the brake is opened to enable the elevator to stably run to a flat bed position in a heavy load direction and manually release trapped people.
At present, a drum type tractor braking device mainly comprises an electromagnetic brake, two braking arms and two braking springs. When the power is off, the brake arm is compressed through the brake spring to achieve the brake-contracting effect, and when the power is on, the brake arm is jacked open through the electromagnetic device to achieve the brake-releasing effect. The brake releasing effect is mainly realized by judging the size of the gap through the magnitude value of the tensioning pressure by the detection block, so that the brake releasing effect is adjusted.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a simple and easy device of hauler stopper gap monitoring that declutches.
The purpose of the utility model is accomplished through following technical scheme: the simple device for monitoring the brake release gap of the tractor brake mainly comprises the brake, lifting hooks, a traction sheave and detection blocks, wherein the lifting hooks are symmetrically arranged on the left side and the right side of the traction sheave, the brake is symmetrically arranged on the left side and the right side of the traction sheave, and the detection blocks are arranged in the brake release gap A of the brake.
The size of the brake release gap A of the brake is 1.0-1.2 mm.
The utility model has the advantages that: the magnitude of brake release clearance tension pressure of the brake during the operation of the elevator is monitored in real time, so that the brake release effect can be controlled and adjusted.
