Before do not have.However steel wire rope sleeve pressing sliding, in the operational process that wirerope uses, the influence to safety is particularly significant, such as cannot
Its true force value is accurately measured, will lead to major safety risks.
Summary of the invention
The purpose of the present invention is to solve the technical problems that steel wire rope sleeve pressing skid force cannot be measured directly, provide
A kind of a kind of measurement method that can quick and precisely measure steel wire rope sleeve pressing skid force and its device.
The present invention utilizes the measuring principle of hollow jack, is adopted using the signals such as hydraulic pump and electric controller closed-loop control
Collection technology installs digital display dynamometer additional by the output end in hollow jack, by the adjustment of parameter, dexterously by installing number additional
Aobvious dynamometer and hydraulic control device, to reach the measurement of steel wire rope sleeve pressing sliding test power fast accurate.Hollow jack two
End should all be placed in steel wire rope sleeve pressing measurement end and fixed end face, it is ensured that uniform force, steady.
A kind of steel wire rope sleeve pressing sliding test detection method and device of the present invention, it is by hollow jack, hollow jack
The devices composition such as stress ring, hydraulic control pump, digital display dynamometer and pressure input, output pipe.
The hollow jack, it is steady that when measurement, ensures to adjust pressurization, pressure release.
A kind of steel wire rope sleeve pressing sliding test detection method and device, it is characterised in that by step is implemented as follows:
(1) hydraulic pump is placed in by tests exemplar, hollow jack be mounted on steel wire rope sleeve pressing one end and another fixation by
Between power end face, hydraulic pump and hollow jack are connected, connects hydraulic pumping source.
(2) relevant parameter for adjusting digital display dynamometer, is allowed to the measurement unit for being shown as needing, and guarantees that pressurization is steadily held
It is continuous, after pressing sleeve is mobile or reaches the sliding force value being pre-designed requirement, stops applying pressure immediately, retract the work of pump
Plug closes power supply, terminates detection test.
The present invention have it is easy to operate it is understandable, steel wire rope sleeve pressing can be quickly detected bear maximum skid force, to produce
Process provides reliable parameter, to guarantee wirerope operational safety.
Detailed description of the invention
It Fig. 1, is a kind of steel wire rope sleeve pressing sliding test detection method and device instrumentation plan.
In figure: 1-hydraulic pump, 2-digital display dynamometers, 3-power supplys, 4-oil pipelines, 5-steel wire rope sleeve pressings, 6-steel

8.Device connection as shown in Figure 1, which is combined, to be constituted, the output end of hollow jack 8 install additional by install additional hydraulic control device and
Digital display dynamometer 2, to reach the measurement of 5 sliding test power fast accurate of steel wire rope sleeve pressing.8 both ends of hollow jack should all place
In 5 measurement end of steel wire rope sleeve pressing and fixed end face, hollow jack stress ring 7, the other end are set in one end of hollow jack 8
If steel wire rope sleeve pressing 5,8 side of hollow jack is connect by the hydraulic device based on oil pipeline 4 and hydraulic pump 1, hydraulic dress
Set setting connection digital display dynamometer 2, by power supply 3 be hydraulic pump 1 provide power and be show dynamometer 2 power supply is provided.
The hollow jack stress ring 7 is to be fastened on cutting ferrule by 2-3 bolt by two semicircular arc cutting ferrules
Its limit is set to bear the pressure of hollow jack 8 on wirerope.
The steel wire rope sleeve pressing 5, one is extended to deform by pressurization with the metal alloy pressing sleeve for having certain ductility
It is fixed on wirerope；Another kind is to use golden pressing sleeve block of the casting of metals on wirerope outer diameter, and it is hollow very heavy to play limit receiving
The pressure effect on top 8.
The hydraulic pump 1, when detection, which ensures newly to pump, should infuse the hydraulic oil met the requirements, steady convenient for loading when measurement
Property；Hollow jack 8 should be accurately installed in place before sliding test detects.
A kind of steel wire rope sleeve pressing sliding test detection method and device, by step is implemented as follows:
(1) hydraulic pump is filled to the hydraulic oil source met the requirements, to more than 3/4 scale of the oil ga(u)ge of oil cylinder, is installed hollow very heavy
