When a steel wire rope suddenly breaks off during a tensile test, the spring can reduce the tensile applied by the front top beam under instant impact to the guide screws, and the guide screws are prevented from being snapped off.
Description
Technical field
The present invention relates to a kind of device for tensile testing machine, specifically, relate to a kind of lineoutofservice signal pull testing machine rupture test buffer unit based on helical compression spring.
Background technology
Steel wire rope is mainly used in the occasion such as lifting, traction, and applying working condition is comparatively severe, in use can produce fretting wear, fatigue rupture, local fracture of wire and deformation, reduce the tensile strength of steel wire rope.For guaranteeing the reusable reliability of steel wire rope, it is carried out pull force calculation according to relevant national standard regulation.In pull test, when the pulling force that steel wire rope bears ruptures suddenly more than self tensile strength, tensile testing machine hydraulic cylinder piston rod back timber before moment impact under hydraulic oil effect, cause force bulb excessive with the guider screw moment pulling force of force seat junction and break, cause that tensile testing machine cannot normally use.
Testing machine working environment is comparatively severe, and force bulb, force seat, guider screw etc. expose for a long time and make sand and dust adhere to, and affect its service behaviour.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, and a kind of lineoutofservice signal pull testing machine rupture test buffer unit based on helical compression spring is provided.
The purpose of the present invention completes by following technical solution: a kind of lineoutofservice signal pull testing machine rupture test buffer unit based on helical compression spring, primary structure includes front back timber, sensor, force seat, guide positioning plate, screw, guider screw, left platen, spring, force bulb, right platen, protective cover, hydraulic cylinder, described sensor is fixed on described front back timber by soket head cap screw, and described force bulb, force seat are connected with described hydraulic cylinder piston rod, sensor respectively through helicitic texture.
Described left platen, right platen are respectively fitted on described force bulb, hydraulic cylinder piston rod, and six equally distributed described guider screws exert a force bulb and described force seat couples together by described left platen, right platen by described.
Described spring housing is on described hydraulic cylinder piston rod, and between described left platen and described right platen.
Described guide positioning plate is welded on described front back timber, and described protective cover is embedded in described guide positioning plate, and by described screws clamp.
The actual gain that the present invention produces is as follows: (1) spring housing is on hydraulic cylinder piston rod, and the utilization of left platen and right platen, can make guider screw uniform force, improves force bulb and the axiality of force seat.
(2) when steel wire rope ruptures suddenly in pull test, the characteristic of spring-compressed energy storage is relied on, pulling force to guider screw when back timber is subject to moment impact before reducing, it is prevented that guider screw breaks, and reduces device vibrations, it is ensured that equipment is properly functioning.
(3) protective cover is embedded in guide positioning plate, and by screws clamp, protection force bulb, force seat, guider screw etc. are not damaged by the external world, and is easy to dismounting and checks.
