Abstract
The utility model discloses an elongation performance testing device of a wire rope for an elevator, which comprises a support frame, a fixed plate, a moving plate, a hydraulic cylinder and a control box, wherein the fixed plate and the moving plate are arranged on the support frame in parallel, and the fixed plate is fixedly connected with the support frame; the moving plate is slidably connected with the support frame, and a piston rod of the hydraulic cylinder is fixedly connected with the moving plate; a cylinder body of the hydraulic cylinder is connected with the support frame, and an oil port of the hydraulic cylinder is connected with a hydraulic power system in the control box through oil pipes; travel switches are also arranged on the support frame, and triggering pieces are arranged on the moving plate corresponding to the travel switches; and the travel switches are electrically connected with a control system in the control box. In the utility model, the elongation of the wire rope can be more precisely measured, and the error generated by the manual measurement of the elongation of the wire rope can be avoided.
Description
Technical field
The utility model relates to a kind of performance testing device, relates in particular to a kind of elevator rope stretch performance testing device.
Background technology
At present with the method for testing of rope stretch performance be: wire rope is fixed on the bottom plate to elevator, on wire rope, do two marks with marking pen, rotary handle, wire rope is applied the pulling force of 3%MBL by oil circuit, measure length between two marks with chi then, note is initial length L, will apply pulling force again and be increased to 8%MBL, the back unloading, 5 times repeatedly, be forced into 3% then, measure length between two marks with chi, note is done length L 1, be forced into 8% again, measure length between two marks with chi, it is L that note is done length L 2. steel wire original lengths, and the construction of wire rope length growth rate is (L1-L)/L under the 3%MBL pulling force so; The elastic extension of wire rope is (L2-L1)/L under the 3%-8%MBL pulling force.This testing apparatus falls behind, and can accurately not load, and simultaneously, the measurement of rope stretch amount is by draw two marks on wire rope, and is not enough to carrying out measuring accuracy before loading and after loading respectively with the length chi.
The utility model content
The utility model is intended to overcome above the deficiencies in the prior art, and a kind of measurement elevator rope stretch performance testing device accurately is provided.
The utility model technical solution problem adopts following technical scheme:
A kind of elevator rope stretch performance testing device, comprise bracing frame, fixed head, movable plate, hydraulic cylinder, control box, described fixed head and movable plate are set in parallel on the bracing frame, described fixed head is fixedlyed connected with bracing frame, described movable plate slidably is connected with bracing frame, the piston rod of described hydraulic cylinder is fixedlyed connected with movable plate, and the cylinder body of hydraulic cylinder is connected with bracing frame; Be provided with control system and hydraulic power system in the described control box; The hydraulic fluid port of described hydraulic cylinder is connected with hydraulic power system by oil pipe, also is provided with displacement transducer on bracing frame, and described displacement transducer one end is connected with movable plate by nylon wire, and the other end is connected with control system.
Further, on bracing frame, also be provided with travel switch, the corresponding triggering part that is provided with on movable plate with travel switch, described travel switch is electrically connected with control system.
Elevator of the present utility model with the principle of work of rope stretch performance testing device is: wire rope one end is connected with fixed head, the other end is connected with movable plate, control system control hydraulic power system loads movable plate by hydraulic cylinder, movable plate applies pulling force to wire rope, rope stretch, the rotating shaft of displacement transducer by inside be wound in rotating shaft on and the nylon wire that is connected with movable plate go out the elongation of wire rope, and this signal passed to control system, thereby calculate the elastic extension of wire rope, the effect of travel switch is to prevent that fortuitous event from occurring, in case wire cable rupture, movable plate is run into travel switch, and equipment will be out of service.
The beneficial effects of the utility model are embodied in the following aspects:
1, the use of displacement transducer is more accurate to the measurement of steel wire elongation, the error of having avoided manual measurement rope stretch amount in the past to be produced.
2, by control system control hydraulic cylinder wire rope is loaded, load more accurate.
3, elevator of the present utility model is simple in structure, easy to make, easy to use with the rope stretch performance testing device.
