Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as Figure 1 to Figure 14 As shown, an elevator overspeed governor safety gear linkage test platform includes:

[0043] A support 1, which is provided with two vertical guide rails 11 extending from the bottom of the support to the top of the support;

[0044] The test frame 2 used to simulate the movement of the car can save space and cost by replacing the real car with the test frame, making the structure simpler and more intuitive, which is convenient for students to observe and study. The first guide shoe 21 makes the test rack move up and down along the direction of the guide rail 1;

[0045] The speed limiter 3 used to detect whether the test frame 2 is overspeed is installed on the support 1;

[0046] The safety gear (not shown) linked with the speed limiter 3 is installed on the test frame 2, and under the manip...

Abstract

The invention relates to an elevator speed governor safety gear linkage testing platform, which comprises a bracket, a testing frame, a speed governor, a safety gear, a pulling frame, a lifting mechanism and a lifting hook mechanism, wherein the bracket is provided with two vertical guide rails; the testing frame is used for simulating movements of an elevator car, and the testing frame is provided with first guide shoes; the speed governor is used for detecting whether the testing frame is overspeed or not; the safety gear is in linkage with the speed governor; the pulling frame is provided with second guide shoes so as to enable the pulling frame to rise and fall along the guide rails, and the pulling frame is located above the testing frame; the lifting mechanism is used for driving the pulling frame to rise; and the lifting hook mechanism is arranged between the pulling frame and the testing frame, the pulling frame and the testing frame are hooked together through the lifting hook mechanism and rise together under driving of the lifting mechanism, the lifting hook mechanism unhooks automatically when the pulling frame and the testing frame rise to a certain height so as to enable the pulling frame to be separated from the testing frame, and the testing frame is released and falls freely along the direction of the guide rails. The elevator speed governor safety gear linkage testing platform is simple in structure, easy to implement, small in occupied space and more suitable for being used in teaching and training.

Description

technical field [0001] The invention relates to an elevator speed governor safety gear linkage test platform. Background technique [0002] Elevator is a kind of vertical lifting transportation equipment, which is used to carry passengers or goods. Existing elevators for use are composed of eight major systems such as guide, traction, car, door, balance, safety, drag, and control, and are scattered in places such as wells, machine rooms, and landings. With the development of economy and society, elevator professional and technical personnel are far from meeting the needs of the elevator market. In order to meet the needs of the market, some colleges and universities have set up elevator majors to train elevator professional and technical personnel. [0003] However, since the real elevator cannot break all the traction wires, during the teaching process of the linkage test of the speed limiter and safety gear of the car free fall and overspeed, it cannot directly reflect t...
