Description
Technical field
The utility model is related to bituminous paving test apparatus field, more particularly to a kind of vehicle tracking test instrument.
Background technology
Vehicle tracking test instrument is the instrument for carrying out wheel tracking test to bituminous paving.
Common vehicle tracking test instrument is as shown in Figure 1, including test platform 1, be set on test platform 1 and for fixed examination
The fixing piece 2 of block 9, test cart 4, the actuator 8 for driving test cart 4 to move and placement for roll off test block 9
In the clump weight 43 on test cart 4, fixing piece 2 includes the fixed frame 21 being set on test platform, is threadedly connected to fixation
Four standing screws 22 of 21 surrounding of frame and be rotatably dispose on the one end close to each other of standing screw 22 and for contradict examination
The fixed plate 23 of block 9.When in use, rotation standing screw 22 makes close to each other to contradict test block 9 between four fixed plates 23, most
Test block 9 is fixed between four fixed plates 23 at last.
Since the structural strength of bituminous paving at different temperature can be varied from, often needed when carrying out wheel tracking test
It to be tested at different temperatures, in test since temperature change, the shape size of pitch test block can change, work as examination
Block becomes hour, and gap is will produce between fixed plate and test block, is loosened, and needing to rotate standing screw again makes fixed plate push against
Test block, operation are more troublesome.
Utility model content
The purpose of this utility model is to provide a kind of vehicle tracking test instrument, can be automatic when pitch test block size changes
Test block is pushed against to prevent test block from loosening.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of vehicle tracking test instrument,
Including test platform, be set on test platform and for fix the fixing piece of test block, the test cart being set in test block with
And the actuator for driving test cart to be moved in test block, counterweight is provided at the top of the test cart, it is described solid
Determine part to include the fixed frame being set on test platform, be threadedly connected to the standing screw of fixed frame surrounding and be rotatably dispose in
Fixed plate on standing screw one end close to each other and for contradicting test block, sets between the fixed plate and standing screw
It is equipped with bolster, the bolster includes that fixation is fixed in the buffer board being rotatably dispose on standing screw, at least two one end
On plate and the other end slides the slide bar being set on buffer board and the buffer spring being sheathed on slide bar, the buffer spring two
End contacts in fixed plate and buffer board respectively.
By using above-mentioned technical proposal, test block is positioned on test platform and is consolidated by fixing piece by when use
Fixed, counterweight is positioned on test cart, move in test block using actuator driving test cart thus to test block into driving
Rut is tested, and when fixed, makes standing screw move along fixed frame to drive fixation to test block direction by rotary fixing screw bar
Plate gives fixed plate due to test block and to delay to the active force in buffer board direction close to test block when fixed plate and test block conflict
Spring contraction is rushed, being rotated further standing screw makes active force between test block and fixed plate increase and buffer spring in the process
Continuation is compressed, and buffer board is moved to test block direction, and stop rotating standing screw when the length of buffer spring is less than setting value,
At this point, test block is fixed between fixed plate, when heating up to test block, test block expansion is to increase the active force of fixed plate
Greatly, buffer spring is made to continue to shrink, when cooling down to test block, test block is reduced, and test block reduces the active force of fixed plate, Gu
It is simple in structure between fixed board is fixed on fixed plate always to the movement of test block direction under the active force of buffer spring and by test block,
Test block can be fixed well when temperature change influences test block size.

It is equipped with hook, hook coordinates with barb to lift briquetting when the piston rod of the lifting cylinder is shunk, the lifting cylinder
Piston rod elongation when hook with barb be detached from.
By using above-mentioned technical proposal, briquetting is hung on by barb on hook, in use, the piston rod of lifting cylinder
Briquetting moves down under the effect of gravity when extending downwardly, when briquetting is pressed in test block upper surface, for test block to the branch of briquetting
Support acts on so that hook is detached from barb, when needing replacing test block, the piston rod of lifting cylinder is made to shrink upwards, and hook rises
And be gradually in contact with barb and barb is pulled to rise to lift briquetting, facilitate the replacement of test block, it is easy to operate, briquetting is slided
Shifting is connected to contradict and can be limited to briquetting on frame, prevents briquetting horizontal position from changing.
It is further arranged to：It is provided with lifting cylinder on the test platform, sliding slot, institute are provided on the test cart
The piston rod for stating lifting cylinder is vertically arranged and passes through sliding slot, the piston rod of the lifting cylinder to be located on the part below sliding slot
It is provided with conflict piece.
By using above-mentioned technical proposal, the bottom surface phase to contact assemblies with sliding slot when being lifted the piston rod contraction of cylinder
It contradicts to drive test cart to rise together, when actuator drives test cart to move horizontally, is lifted the piston rod of cylinder
It can be slid along sliding slot, it is simple in structure, test cart can be lifted and the installation for carrying out test block is facilitated to fix.
It is further arranged to：The actuator includes the second cylinder that piston rod is connect with test cart, second gas
Cylinder is set on test platform and piston rod is arranged in parallel with sliding slot, and the piston rod of second cylinder is with test cart vertical
Setting is slid on direction.
By using above-mentioned technical proposal, energy band dynamic test trolley is horizontal in test block when the piston rod of the second cylinder is flexible
It moves back and forth, piston rod and the test cart of the second cylinder slide setting in the vertical direction can ensure that being lifted cylinder pulling tries
Testing test cart when trolley rises can rise, and simple in structure, driving effect is good.
It is further arranged to：The piston rod part of second cylinder is provided with sliding sleeve, is provided on the test cart
Guide rod, the guide rod penetrate in sliding sleeve.
By using above-mentioned technical proposal, sliding sleeve is moved with the stretching for piston rod of the second cylinder, when sliding sleeve moves
The guide rod that penetrates in sliding sleeve is driven to move together to change test cart and rolled in test block.
It is further arranged to：The counterweight includes the balancing disk being set on test cart and is positioned in balancing disk
Clump weight.
By using above-mentioned technical proposal, using clump weight to balancing disk progress counterweight to change the load of test cart,
To carry out the wheel tracking test under different loads.
In conclusion the utility model has the advantages that：
1, fixed plate is contradicted in test block by the buffer spring of bolster, is made when the size of test block changes
Fixed plate is inconsistent with test block always, ensures that, in temperature change, test block can be fixed preferably always；
2, coordinated by sliding sleeve and guide rod, sliding sleeve with the piston rod of the second cylinder moves back and forth when drive and try
Trolley movement is tested, while ensure that up and down motion of the test cart with lifting cylinder, simple in structure, driving effect is good；
