The utility model has the advantages of easy operation, application scope are extensively.
Description
Technical field
The utility model relates to a kind of test platform for static loading and fatigue loading, is specifically related to a kind of Multifunction levelling test base.
Background technology
Existing test base is mainly steel plate or framed structure, and structure is comparatively simple, is mainly test test specimen and provides a horizontal operation plane.In use, mainly there is following shortcoming in existing test base:
(1) height can not be regulated.Existing test base is substantially all a fixing specification, limits its scope of application to a certain extent, if the distance of test test specimen and charger excessive or too small time, test is possibly cannot be carried out.
(2) levelness is difficult to control.Existing test base does not possess the function of adjustment levelness, although can by regulating at bottom pad pad or other forms, precision be difficult to control.
How to design a kind of test base simple to operate, wide adaptability and become technical matters urgently to be resolved hurrily.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of Multifunction levelling test base of simple to operate, wide adaptability.
Technical scheme: for solving the problems of the technologies described above, the Multifunction levelling test base that the utility model provides, comprising:
Upper strata steel plate, for carrying test specimen;
Leveling bolt, is located between upper strata steel plate and concrete pit guidance tape, for adjusting the levelness of upper strata steel plate;
Foot bolt, for connecting upper strata steel plate and concrete pit guidance tape;
The linkage interface of described leveling bolt and upper strata steel plate is wedge structure.
As preferably, described wedge structure comprises steel diagonal brace and jacking block, and described steel diagonal brace is fixed on the back side of upper strata steel plate, and described jacking block has the inclined-plane matched with steel diagonal brace.
As preferably, described upper strata steel plate is rectangular, the length direction of described rectangle is fixed with pair of parallel steel floor, and described steel diagonal brace is fixed between steel floor and two long limits of rectangle, and described foot bolt is arranged along the length direction of rectangle.
As preferably, described foot bolt is connected to the two ends of rectangle, and is positioned on the center line of rectangle.
As preferably, nut and the upper strata steel plate of described foot bolt press-fit fixing, and the two ends of described rectangle have the U-shaped breach of the screw rod for embedding foot bolt.
As preferably, between described leveling bolt and concrete pit guidance tape, be provided with steel plate washer.
During use, two steel floors are welded in steel plate both sides, upper strata, steel diagonal brace keeps at a certain distance away and is welded in upper strata steel plate and steel floor, leveling bolt unidirectional connection upper strata steel plate, bottom and layer contacts, steel plate washer is placed on concrete pit guidance tape, and base entirety and concrete pit guidance tape are fixed together by foot bolt.
The course of work is as follows:
The first step: according to design drawing welding upper strata steel plate, steel floor and steel diagonal brace composition top work body, meanwhile, leveling bolt is screwed in the work body of top.
Four pieces of steel plate washers are placed in place by second step: experimentally requirement.
3rd step: regulate leveling bolt.Tentatively adjust the height of leveling bolt according to the distance testing test specimen and charger, test specimen be can be good at stressed, afterwards by surveyor's staff, fine setting leveling bolt, makes upper strata steel plate be up to the standard.
4th step: mounting foot bolt, is fixed together base entirety and concrete pit guidance tape.
Beneficial effect: the design except upper strata steel plate, steel floor and steel diagonal brace be except welding operation, all the other components all can be processed separately, and take assembling method can assemble experiment bottom platform, simple to operate, realizability is large.Provide Level tune hold concurrently highly regulate test platform, applicability is wider.Be not only applicable to static loading, and be applicable to fatigue loading, the test specimen offset problem that when having stopped fatigue loading, test platform levelness causes not.
Except technical matters, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the utility model recited above solves, the advantage that the other technologies feature comprised in the other technologies problem that Multifunction levelling test base of the present utility model can solve, technical scheme and these technical characteristics bring, will be described in more detail by reference to the accompanying drawings.
