It sets.It compensates for simulant building tangential displacement of the isolation rubber pipe in earthquake, to test tubing under corresponding condition
Life expectancy and endurance ratio.
Background technique
Architectural vibration-insulation rubber tube is largely buried use, is affected by formation variation.When earthquake or stratum become
When change, tubing will receive corresponding power and change.And the variation on stratum be it is uncertain, not only have lateral stretching or pressure
Contracting, while also having longitudinal rise or fall.It therefore, is axial and radial combination to the influence of tubing.
Existing tubing test device such as has the drawback that one, can only the axial direction of tubing be stretched and be compressed at the objects
Property test, cannot effectively simulate tubing by it is axial with radial binding force the case where, affect the accuracy of test；Two,
Existing test device has a single function, and does not have the function of a tractor serves several purposes；Three, its tangential displacement rate of existing test device
400mm/s that is low, not reaching requirement, especially in commutation, the time is long, and speed is slow, affects test result.
Summary of the invention
The object of the present invention is to provide a kind of architectural vibration-insulation rubber tube tangential displacement test devices, can give test tubing
Simultaneously or separately apply the axial power with radial direction, to effectively simulate the stress condition in practical application, makes test result more
Accurately.
The present invention is achieved through the following technical solutions: a kind of architectural vibration-insulation rubber tube tangential displacement test device,
It is characterized in that: including rack, slipping the vertically-mounted seat of cooperation with rack and be horizontally mounted seat；Fixation is set above vertically-mounted seat
There is limit skateboard, limit skateboard slips on the upright slide rail of rack two sides, first hydraulic cylinder is fixed with above rack,
The free end of first hydraulic cylinder passes through rack and fixes with slide plate；It is horizontally mounted below seat and is fixed with sleeve, sleeve is slipped in platform
On horizontal slide rail below frame, it is fixed with second hydraulic cylinder in the side of rack, the free end of second hydraulic cylinder passes through rack
It is fixed with seat is horizontally mounted；Vertically-mounted seat and the opposite face for being horizontally mounted seat are equipped with mounting hole, mounting hole and building to be measured
The end socket of isolation rubber pipe matches.
Further, being equipped with sensor in vertically-mounted seat and/or the inside for being horizontally mounted seat.
The invention has the advantages that structure of the invention can a tractor serves several purposes, when vertically-mounted seat and be horizontally mounted seat and fix one
When, it can be achieved that the individually load in horizontal and vertical direction；When being not fixed, can be realized simultaneously both vertically as well as horizontally plus
It carries；By the cooperation of the two, the simulation of a variety of use conditions may be implemented, to improve the accuracy of test result, be conducive to
The performances such as destruction and fatigue to tubing are monitored, in addition, the machine tangential displacement rate is fast, direction conversion time is non-every the time
It is often small, substantially increase the accuracy of test.Using the angle of rolling guide slide block mechanism constraint test specimen mounting surface, it is allowed to cutting
It does not rotate, is reduced because test specimen stretches radial load caused by axial force increase during to racking test.

Specific embodiment
It is as shown in Figs. 1-3 a kind of architectural vibration-insulation rubber tube tangential displacement test device of structure of the invention, it is possible to provide 10 lis
Meter or more tangential displacement；It includes rack 1, slips the vertically-mounted seat 2 of cooperation with rack and is horizontally mounted seat 3；Vertical peace
It is fixed with limit skateboard 4 above dress seat, limit skateboard slips on the upright slide rail 5 of rack two sides, solid in the top of rack
Surely it is equipped with first hydraulic cylinder 6, the free end of first hydraulic cylinder passes through rack and fixes with slide plate；It is horizontally mounted below seat and is fixed with
Sliding block 7, sliding block slip on the horizontal slide rail 8 below rack, are fixed with second hydraulic cylinder 9, the second liquid in the side of rack
The free end of cylinder pressure passes through rack and fixes with seat is horizontally mounted；Vertically-mounted seat and the opposite face for being horizontally mounted seat are equipped with installation
Hole, mounting hole are matched with the end socket of architectural vibration-insulation rubber tube to be measured.
It is preferred: to be equipped with sensor in vertically-mounted seat and/or the inside for being horizontally mounted seat.
It is preferred: locking device to be equipped on limit skateboard, which includes the limit screw hole being arranged on limit skateboard
10, be arranged in limit screw hole on caging bolt 11, caging bolt and limit screw hole threaded, and may pass through limit screw hole with
Upright slide rail matches.
Preferred: the mounting base (vertically-mounted seat and/or be horizontally mounted seat) is the box body that side is equipped with opening 33
Structure, the other side of box body are equipped with the bolt mounting holes 32 and a through-hole 31 of multiple strips, and mounting hole is used for and mounting base
Fixing bolt match, installation site is conveniently adjusted, by for passing through the pressure supply sebific duct etc. of connecting pipe and from opening
Side is pierced by be connected with external equipment of suppressing, to pressurize during the experiment to tubing.It is horizontally mounted below seat and is provided with sliding block,
