Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] see figure 1 , The test bench for elevator emergency test includes: load motor 1, emergency workbench 2, host 3. The load motor 1 provides the load for the testing machine, the emergency workbench 2 simulates the emergency working condition of the elevator, and the host machine 3 needs to measure data related to its traction capacity.

[0021] see figure 2 , image 3 , Figure 4 , The emergency workbench 2 includes: a disc spindle 21, a disc 22, an adjustment bracket 23, a wire rope 24, a regulator 25, and a bracket 4. Wherein the disc 22 is connected to the disc main shaft 21, the disc main shaft 21 is mounted on the bearing mounting bracket 4, and the adjustment bracket 23 is inserted into the disc angle adjustment hole 221 of the di...

Abstract

The present invention relates to device for detecting the drag capacity in emergency work condition, and is especially one lift test table for detecting the drag capacity of lift in emergency work condition on the ground. The lift test table includes a system unit, a load motor, a disc, a steel cable, a disc main shaft, a regulating rack and a regulator. The emergency work condition is simulated with the emergency work condition workbench, the steel cable drives the system unit to run owing to the friction force between the drag wheel and the steel cable and the simulation load of the system unit is increased without load motor. After the speed of the system unit is increased to the rated value of the lift, the power is turned off before contracting brake while recording the rotation number and braking period of the system unit from deceleration to stop so as to obtain the deceleration and the displacement of the system unit and the sliding amount of the steel cable in emergency work condition.

Description

technical field [0001] The invention relates to a device for testing traction capacity in emergency working conditions, in particular to a test bench for testing elevator traction capacity on the ground in emergency working conditions. Background technique [0002] The lifting system of the elevator is composed of traction machine, car, counterweight, traction wire rope and main and auxiliary guide rails. The traction machine is fixed on the top of the hoistway. The friction between the wire rope and the wire rope makes the wire rope move up and down, and the traction car and the counterweight move up and down. When the elevator is in an emergency working condition, how to test the traction capacity of the elevator, how to obtain the speed, displacement, and relative slippage of the steel rope of the elevator host, Chinese patent announcement CN01822523.3 provides a state about the elevator traction rope or transmission belt Information checking device that checks the most ...
