Description
Technical field
The utility model relates to a kind of automatic following system, particularly rubber support pressure-shear test machine lateral shear device automatic following system.
Background technology
Usual rubber support is combined closely by rubber and sheet steel and is formed, and for supporting and transmitting upper load, regulates translation and rotation by the distortion of rubber, thus regulates the relative displacement between superstructure and substructure.The rubber support pressure-shear test machine lateral shear device of current production, general employing lift cylinders balance, its jacking gear adopts oil cylinder to support, or horizontal frame height of cutting is fixed, adjust height by four-column type pressure test Oil cylinder, do transverse shearing test, the defect existed is in test due to sample deformation, cause Heng Jian center of effort's point to change, affect test findings, the accurate requirement of test method(s) cannot be met.
Summary of the invention
The purpose of this utility model is to overcome the some shortcomings existed in above-mentioned prior art, provides a kind of rubber support pressure-shear test machine lateral shear device automatic following system rational in infrastructure, flexible and convenient to use.
For achieving the above object, the technical scheme of the utility model institute technical solution problem is: rubber support pressure-shear test machine lateral shear device automatic following system have employed lift cylinders and bearing pin equilibrium principle, rubber support pressure-shear test machine lateral shear device automatic following system is made to have accomplished real-time follow-up, horizontal acting force of cutting acts at the over center position all the time, like this when doing horizontal scissor test, the deadweight of lateral shear device can be eliminated completely, ensure that the accuracy of test findings.
The rubber support pressure-shear test machine lateral shear device automatic following system that the utility model provides, is mainly used in the shear test of rubber support.Its by hoist cylinder, track, horizontally cut arm-tie, pin framework, front straining beam, horizontally cut oil cylinder seat, horizontally cut oil cylinder, horizontally cut piston, load sensor, rear straining beam, nut, guide wheel, wheel, little car body, guide pillar, tie-bar, screw form.
Hoist cylinder is connected with little car body and horizontal oil cylinder seat of cutting respectively by screw, horizontal oil cylinder of cutting is contained in horizontal cutting in oil cylinder seat and is connected with load sensor, tie-bar is connected to form a pulling force framework by nut and front straining beam and rear straining beam, and pulling force framework by tie-bar scroll forward and backward on guide wheel, thus produces pulling force.Front straining beam is connected with horizontal arm-tie of cutting by bearing pin, and rear straining beam is connected with load sensor, relies on guide pillar guiding during hoist cylinder lifting, and lateral shear device entirety along track travel, realizes the movement of lateral shear device by wheel.
the beneficial effects of the utility model:the utility model have employed lift cylinders and bearing pin equilibrium principle, rubber support pressure-shear test machine lateral shear device automatic following system is made to have accomplished real-time follow-up, horizontal acting force of cutting is acted at the over center position all the time, automatically bearing pin adjusting mechanism is followed owing to have employed, the deadweight of lateral shear device can be eliminated completely, make sample horizontal axis stressed, solve in test due to sample deformation, cause Heng Jian center of effort's point to change.There is processing ease, the advantage that cheap, test findings is accurate, easy to use.
Accompanying drawing explanation

concrete implementing method
Below in conjunction with accompanying drawing, the utility model is described in further detail: rubber support pressure-shear test machine lateral shear device automatic following system, its by hoist cylinder 1, track 2, horizontally cut arm-tie 3, pin framework 4, front straining beam 5, horizontally cut oil cylinder seat 6, horizontally cut oil cylinder 7, horizontally cut piston 8, load sensor 9, rear straining beam 10, nut 11, guide wheel 12, wheel 13, little car body 14, guide pillar 15, tie-bar 16, screw 17 form.
Refer to shown in Fig. 1: hoist cylinder 1 is connected with little car body 14 and horizontal oil cylinder seat 6 of cutting respectively by screw 17, horizontal oil cylinder 7 of cutting is contained in horizontal cutting in oil cylinder seat 6 and is connected with load sensor 9, tie-bar 16 is connected to form a pulling force framework by nut 11 and front straining beam 5 and rear straining beam 10, pulling force framework by tie-bar 16 scroll forward and backward on guide wheel 12, thus produces pulling force.Front straining beam 5 is connected with horizontal arm-tie 3 of cutting by pin framework 4, and rear straining beam 10 is connected with load sensor 9, relies on guide pillar 15 to lead when hoist cylinder 1 is elevated, and lateral shear device entirety is walked along track 2 by wheel 13, realizes the movement of lateral shear device.
Transverse shearing test device automatic following system, the mainly lifting of hoist cylinder 1, the end play of pin framework 4 makes front straining beam 5 and horizontal automatic adjustment of cutting arm-tie 3, ensure that horizontal center of cutting arm-tie 3, driven by little car body 14, lateral shear device enters test space, and automatic following system starts, the deadweight of lateral shear device is eliminated completely, reaches tested sample horizontal axis stressed.
Owing to adopting the automatic following system of pin framework 4, horizontal deadweight of cutting device is eliminated completely, guarantee that tested sample horizontal axis is stressed identical with lateral shear center of effort, ensure that the accuracy of test findings, according in " JT/T4--2004 slab rubber bearing in Highway Bridge mechanical test method " A.3.2: when carrying out shear test, the cross cylinder of its shear test mechanism, the axis of load sensor should coincide with the axis of symmetry of middle steel arm-tie, guarantee the requirement that tested sample horizontal axis is stressed, make the requirement of the complete Pass Test method of whole test, meet the accurate requirement of test method(s), solve technician's puzzlement at work.
