Problems solved by technology
[0006] In the above-mentioned invention, the rotating shaft of the motor under test is connected to the main shaft of the torque speed measuring instrument through a coupling, and the two brackets supporting the rotation of the main shaft are fixedly arranged. In this way, there are the following problems: when installing the above-mentioned torque speed When using a measuring instrument, the axis of the main shaft on it needs to coincide with the axis of the rotating shaft of the motor in order to obtain accurate measurement results. However, the two fixed brackets make it difficult to adjust the axis of the main shaft. The ground coincides with the axis line of the motor's rotating shaft

The invention discloses a torque and rotation speed measurement device of an anti-falling safety device, which comprises a support, a main shaft, a rotation speed measurement system and a torque measurement system, wherein the rotation sped measurement system is connected on a rotation speed gauge head by a speed measurement electric generator and used to read a rotation speed of an electric motor; the torque measurement system generates mutual acting force by electromagnetic induction force between a rotor which is connected to the tested electric motor and a shell which covers the rotor, and the torque measurement system also knows size of torque output by the tested electric motor according to a deflection range of the shell under a torque effect of the rotor; the support comprises a chassis, a left support and a right support; and the main shaft used for installation of the rotor is pivoted on the left support and the right support, heights of the left and right supports are adjustable, so that an operator can easily adjust levelness and a height of an axial line of the main shaft while installing the torque and rotation speed measurement device, and thus the main shaft axial line can be coincided with a rotation shaft axial line of the tested electric motor, and accuracy of measurement results can be guaranteed.
Description
Technical field: [0001] The invention belongs to the technical field of elevators or other electric-driven lifting equipment, and in particular relates to a torque and rotational speed measuring device for a safety device against falling. Background technique: [0002] Its main form of anti-falling safety device both at home and abroad at present has gear bevel drum shape progressive anti-falling safety device and instantaneous type anti-falling safety device. The traction machine used on the construction hoist does not have a two-way anti-drop safety device that automatically prevents the cage from falling and the heavy objects from falling. Therefore, it is urgent to install an overload protection device on the hoist. The rated weight of heavy objects and standardizing the installation or disassembly of traction-type cargo construction hoists are the most important work and direction of our lifting equipment management workers. Lifts generally have a mechanical self-locki...
