Abstract
The utility model relates to a variable-length loading rack of a damper comprising a load frame. One end of the loading frame is a hydraulic loading end. The loading frame is provided with a guide rail and a walking device capable of moving along the guide rail. The walking device is provided with a cross beam, a lower part of which is movably provided with moving blocks in a suspended manner. The inner side of the loading frame is provided with a plurality of positioning blocks cooperated with the moving blocks, and each two adjacent positioning blocks can be used to clamp the corresponding moving block. The variable-length loading rack of the damper has advantages of convenient operation, firm fixation, and high reliability.
Description
Technical field
The utility model relates to the elongated degree loading frame of a kind of damper, relates in particular to a kind of loading frame being arranged on testing table for damper performance test.
Background technology
The development of damper is very rapid, has been widely used at present the fields such as space flight, aviation, military project, automobile, building, railway.For verifying the accuracy of the performance parameter of damper, need to it, test with damper is comprehensive performance test bed, loading frame on damper experiment table is generally divided into two kinds of measured length and elongated degree, the loading frame of measured length exists significant limitation, can not meet the test of the damper of different length specification, therefore loading frame of the prior art is in the majority with the form of elongated degree.
The elongated degree loading frame of damper of the prior art, its version is also often divided into two kinds: a kind of is the version that changes the long limit of loading frame, the length that changes loading frame by the structure on the long limit of sectional type, the loading frame of this structure is comparatively loaded down with trivial details in operation, uses comparatively inconvenience; Another kind is the length that the mode that adopts column hydraulic pressure to step up regulates loading frame, although this structure is easy to adjust, but it is comparatively obvious to step up the impact that power is subject to friction factor, when column surface is polluted and friction factor is changed, hydraulic pressure steps up power and also just changes thereupon, make loading frame fixing insecure, the slippage meeting of column simultaneously consumes larger hydraulic energy, can have influence on the accuracy of test when serious.
Utility model content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, provides a kind of damper elongated degree loading frame, and it is easy to operate, fixation, and reliability is higher.
The purpose of this utility model is to be achieved through the following technical solutions:
The elongated degree loading frame of damper, comprise loading frame, one end of described loading frame is hydraulic loaded end, the running gear that described loading frame is provided with guide rail and moves along described guide rail, described running gear has crossbeam, described crossbeam underside is hung and is provided with mobile block, and the inner side of described loading frame is provided with the locating piece that a plurality of and described mobile block matches, the described mobile block of adjacent two locating pieces clamping.
Further, the side that described mobile block is relative with described hydraulic loaded end is provided with damper connector.
Further, described running gear and described guide rail are rolling wheel guide rails formula.
Further, described crossbeam is established described mobile block by screw mandrel movable hanging.
Further, described crossbeam is provided with the worm gearing being connected with described screw mandrel, in order to drive described screw mandrel to rotate.
Further, between described locating piece and described mobile block, be provided with a pair of gap voussoir that disappears coordinating by inclined-plane, one of them gap voussoir that disappears is fixedly connected with locating piece, and another gap voussoir that disappears is fixedly connected with described mobile block.
Further, on described loading frame, be also provided with dismountable tie-beam.
The elongated degree loading frame of damper described in the utility model, comprise loading frame, one end of described loading frame is hydraulic loaded end, the running gear that described loading frame is provided with guide rail and moves along described guide rail, described running gear has crossbeam, described crossbeam underside is hung and is provided with mobile block, and the inner side of described loading frame is provided with the locating piece that a plurality of and described mobile block matches, the described mobile block of adjacent two locating pieces clamping.The elongated degree loading frame of damper of this structure, it is easy to operate, fixation, reliability is higher.
Accompanying drawing explanation

Fig. 2 is the local amplification stereogram at running gear place in Fig. 1.
Embodiment
According to drawings and embodiments the utility model is described in further detail below.
As shown in Figures 1 and 2, the elongated degree loading frame of damper of the utility model embodiment, comprise loading frame 1, one end of loading frame 1 is hydraulic loaded end 2, the running gear 4 that loading frame 1 is provided with guide rail 3 and moves along guide rail 3, running gear 4 has crossbeam 41, and crossbeam 41 underside are hung and are provided with mobile block 5, the inner side of loading frame 1 is provided with the locating piece 6 that a plurality of and mobile block 5 matches, the mobile block 5 of adjacent two locating pieces, 6 clamping.
The side that mobile block 5 is relative with hydraulic loaded end 1 is provided with damper connector 51.Running gear 4 is rolling wheel guide rails formula with guide rail 3.Crossbeam 41 is established mobile block 5 by screw mandrel 42 movable hangings.
Crossbeam 41 is provided with the worm gearing 43 being connected with screw mandrel 42, in order to drive screw mandrel 42 to rotate.
In order further to strengthen the stability between mobile block and locating piece, between locating piece 6 and mobile block 5, be provided with a pair of disappear gap voussoir 7a, the 7b coordinating by inclined-plane, one of them gap voussoir 7a that disappears is fixedly connected with locating piece 6, and another gap voussoir 7b that disappears is fixedly connected with mobile block 5.By the effect of gravity, mobile block 5 drops between adjacent locating piece 6 and closely and connects.On loading frame 1, be also provided with dismountable tie-beam 8.
The foregoing is only explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
