Description
Technical field
The utility model relates to the field tests of mechanical part, is specifically related to a kind of tensile test seat.
Background technology
Chain is generally chain link or the annulation of metal, multiplexly does mechanical drive, traction.Chain is four kinds, driving-chain, carrier chain, dragging chain and special chain by different purposes and function distinguishing.
Dragging chain is mainly used in the chain of towing and lifting.Dragging chain is mainly used in traction elevator.Traction elevator uses the most general a kind of elevator in vertical transportation means of transport.It is all overlength chains that usual chain manufacturer produces dragging chain, and overlength chain refers to the chain of length more than 27.5m.Overlength chain, when specifically using, blocks by client according to specific needs again.
Dragging chain usually needs to carry out leaching and moulds process, and the processing technology referred to chain surface coating plastic is moulded in leaching.Leaching mould after chain has low temperature resistant, shock-resistant, wear-resisting, salt spray resistance, resistance toly to draw, acid and alkali-resistance, ageing-resistant, high pressure resistant, chemicals-resistant, weatherability are excellent, and outdoor use such as can not to crack at the advantage.
The leaching creeping journey of dragging chain mainly comprises :-stamp-discharging is moulded-cooled in charging-leaching.Need to test the performance of chain before feed step, object checks that whether the tensile property of chain is qualified, in order to avoid the inadequate chain of stretching resistance carries out after leaching moulds, coming into the market.Because dragging chain is mainly used in elevator industry, the quality of chain quality directly has influence on the life safety of passenger, therefore the quality of chain is particularly important.Therefore carry out needing before leaching is moulded to carry out tensile test to every shot of a cable ring at dragging chain.
When usually tensile test being carried out to the chain link of chain, not separately tensile test is carried out to every shot of a cable ring, but carry out tensile test in units of the chain of a certain length.A kind of chain tension parameter test device of such as publication number CN103245564A, discloses, comprises worktable, holder, adapter, tautness meter, dial gauge and acting device; Described acting device is for the tested chain that stretches, and described adapter ensures that the acting force of the height of tested chain and acting device is in same level.This device all needs when often testing the pulling force of one section of chain to be manually locked to chain.Testing efficiency is low as can be seen here.
In sum, for chain manufacturer, being now badly in need of a kind of stationary installation can carry out, in tensile test process, fixing fast chain at chain, has become the sector problem demanding prompt solution.
Utility model content
The purpose of this utility model is providing a kind of in chain pull test process, the tensile test seat can fixed fast chain.
For achieving the above object, the technical solution of the utility model is as follows:
Tensile test seat, comprise holder, holder is provided with limitting casing and back up pad, this back up pad is provided with executive component, swing arm and the first pulley, swing arm is provided with the second pulley, and the first pulley is positioned at above the second pulley, and this swing arm and back up pad are rotationally connected, the end of described executive component and swing arm is rotationally connected, and the second pulley is positioned at directly over limitting casing; Described limitting casing comprises limiting plate, and this limiting plate is provided with the bayonet socket for blocking chain.
Adopt the tensile test seat of the utility model scheme, the first pulley plays a supportive role to chain, and the second pulley changes the direction of chain.Swing arm and back up pad are rotationally connected, and guarantee that swing arm can realize swinging.The end of described executive component and swing arm is rotationally connected, and actuator movement drives swing arm motion.Second pulley is positioned at directly over limitting casing, guarantee that swing arm is when swinging to a certain angle, second pulley can be positioned at limitting casing, thus the limiting plate realized on the limited frame of certain shot of a cable ring of chain below swing arm is blocked, and reaches the fixing object of chain.When swing arm swings to a certain angle, the second pulley is positioned at above limitting casing, and the chain below swing arm departs from from limiting plate.Swing arm reciprocally swinging realizes the fixing and movable of chain.
Principle of work: during concrete use this tensile test seat, first make chain successively through the first pulley and the second pulley, when guaranteeing that chain chain pulls, the first pulley is contrary with the rotation direction of the second pulley.Chain below swing arm is positioned at above limiting plate.When needing the chain below to swing arm to carry out tensile test, start executive component, swing arm is swung, and now the second pulley swings with swing arm, and when the second pulley is positioned at limitting casing, executive component keeps this state.Now swing chain below this wherein shot of a cable ring be stuck in the bayonet socket place on limiting plate.Now the limited board of chain is lived, thus realizes fixing chain.When needs are to when on chain, another section of chain carries out tensile test, make executive component do reverse direction motion, the second pulley moves to the direction away from limitting casing, when the second pulley is positioned at above limitting casing, pull chain, the chain segment needing to carry out tensile test is positioned at below swing arm.Make actuator movement, swing arm swings, and the second pulley moves near the direction of limitting casing, and when the second pulley is positioned at limitting casing, executive component keeps this state.Now swing chain below this wherein shot of a cable ring be stuck in the bayonet socket place on limiting plate.Now the limited board of chain is lived, thus realizes fixing chain.Make executive component to-and-fro movement, can realize fixing fast each chain segment of overlength chain.
Beneficial effect: relative to traditional device for testing tensile force, when carrying out tensile test to chain, manually install bearing pin and be fixed, this tensile test seat can need the chain segment of carrying out tensile test fix fast and switch to overlength chain.
Further, described back up pad is provided with and works to the second pulley the 3rd pulley regulating cornerite, and the cornerite can guaranteed on the second pulley by the 3rd pulley is greater than 120 °, increases the transmission stationarity of chain.
Further, described swing arm is also provided with the passive support bar of chain below to swing arm, when avoiding the second pulley to be positioned at above limitting casing, the chain below swing arm contacts with limiting plate, occurs the phenomenon that the limited board of chain is lived.
Further, described back up pad is provided with the guide plate play the guiding role to swing arm, and reduce swing arm when the tie point place be rotationally connected around swing arm and back up pad, swing arm makes swing arm rock because chain slides on the second pulley.
Further, described executive component is pneumatic cylinder or hydraulic cylinder, for linkage assembly, pneumatic cylinder and hydraulic cylinder more steady.
Further, described limitting casing also comprises U-shaped frame, and limiting plate and U-shaped frame removably connect, and facilitate the processing of limiting plate upper latch notch.
