Problems solved by technology

[0003] In the market, the lifting force testing instrument of speed limiter is mainly measured by manual loading method, and electric method is also used, but the tensile structure adopts complex structures such as reverse rope pulley, which is complicated to operate and low in efficiency, which is not conducive to on-line detection in mass production
In addition, because the national standard requires the integrity of the cross-sectional shape of the steel wire rope, the steel wire rope needs to be replaced after use. The above two types of equipment have no relevant mechanisms to realize this function.

Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1The speed governor test device shown includes a test bench 10 , a rope winding mechanism 20 , a stretching mechanism 30 and a shearing mechanism 40 . The shearing structure 40 , the rope winding mechanism 20 and the stretching mechanism 30 are respectively connected and installed with the test bench 10 . The winding rope mechanism 20 is used for winding and placing the test rope, and the stretching mechanism 30 stretches the test rope during the test, while the stretching mechanism 30 detects the tension of the speed limiter, and the shearing mechanism 40 automatically stretches the test rope after the test is completed. cut.

[0035] Among them, refer to figure 2 The illustrated shearing mechanism 40 includes a first drive assembly 410 , a first rail assembly 420 and a shearing module 430 . The first driving assembly 410 is...

Abstract

The invention discloses a speed governor testing device which comprises a test table, a rope winding mechanism, a stretching mechanism and a shearing mechanism, wherein the shearing mechanism, the rope winding mechanism and the stretching mechanism are respectively connected with the test table; the rope winding mechanism is used for storing and placing the test rope; the stretching mechanism is used for stretching the test rope when testing to detect tension of the speed governor; and the shearing mechanism is used for shearing the test rope after the test. The speed governor testing device can automatically load and measure the speed governor, is simple in the structure, easy to operate, high in efficiency, and suitable for online detection of the speed governor batch production.

Description

technical field [0001] The invention relates to the field of detection devices for elevator components, in particular to a speed governor test device for detecting elevator speed governors. Background technique [0002] The overspeed governor that adopts on the market mainly has two kinds of clamping ways at present, and a kind of is to clamp steel wire rope with clamp block and sheave, and a kind of is to clamp steel wire rope with clamp block and baffle plate. The wire ropes of the two structures have different walking methods. The former needs the wire rope to be wound on the speed governor sheave, while the latter wire rope does not need to be wound on the sheave, and only needs to be put down to clamp the wire rope with the rope clamping block. [0003] The lifting force testing instruments of speed limiters in the market are mainly measured by manual loading, and some also use electric methods. However, the tensile structure adopts complex structures such as reverse ro...
