Abstract
The utility model provides a horizontal tunnel lining module test bed face soil sealing direction guide toggle plate, which belongs to the technical field of civil engineering. Toggle plates are simply arranged on a test bed face, and the bottoms of the toggle plates bear a uniform large friction force at the left and the right, therefore, the left and the right of the toggle plates bear a uniform force, the four toggle plates easily form a rhombus structure to enable wall rock and a lining module to bear a uniform force, and further the result of test is affected. A U-shaped groove is formed below two vertical cross ribs of a push plate; the U-shaped groove is welded on the test bed face; a cylindrical roller is arranged at the bottom of the U-shaped groove; the vertical lower end faces are in tangency with the cylindrical roller; a sliding plate has an I-shaped beam structure, one end of the sliding plate is arranged in a sliding plate groove and is in tangency with the cylindrical roller in the sliding plate groove. The toggle plates are mainly applied in a horizontal tunnel lining module test bed face soil sealing direction guide test.
Description
Technical field
The utility model belongs to technical field of civil engineering, particularly the thrust plate used of tunnel-liner model investigation.
Background technology
Whether but grave mound guiding thrust plate is a key structure in the tunnel-liner model investigation, relate to horizontal thrust and can accurately apply abreast, and whether country rock is inner stressed even, the stressed whether unanimity of lining cutting model etc.
Adopt thrust plate to realize that the level of square country rock loads on four sides, need prevent that country rock is excessive in a large number, therefore guiding and grave mound are the key Design of thrust plate.Existing apparatus mainly contains two kinds, all adopts to place four I shape push pedals of testing table table top to form the hollow structure, and every push pedal is carried out horizontal drive by two hydraulic cylinders.First kind is adopted four the same push pedals; Exceed a part between push pedal successively; When the four sides was stressed, each push pedal all had two kinds of motions: the one, and the reach of hydraulic drive mechanism pushing direction compresses country rock after push pedal, and the one,, contiguous push pedal moves under promoting to contiguous thrust direction.Second kind is adopted two long two short symmetrical structures, adopts L type angle steel and gravity rollers structure between contiguous push pedal, can realize grave mound and mutual slide-and-guide.
Adopt the problem of first kind of structure to be: push pedal simply is positioned on the test table top; The big friction force of inequality caused push pedal left and right sides unbalance stress about the bottom can receive, and four push pedals are prone to form diamond structures; Make and country rock and lining cutting model unbalance stress influence test result; Big friction force also can make the push pedal phenomenon that leans forward, and causes country rock unbalance stress up and down, influences test result.Adopt the problem of second kind of structure to be: because of every push pedal receives two Driven by Hydraulic Cylinder; Push pedal simply is positioned on the test table top; The big friction force of inequality caused push pedal left and right sides unbalance stress about the bottom can receive, and L type angle steel and corresponding gravity rollers are had relatively high expectations; L type angle steel and gravity rollers place that push pedal is inboard to be contacted with country rock, have taken the country rock inner space, make country rock stressed become two-layer, promptly push pedal plane and chute outward side plane all participated in the transmission of power, make the country rock unbalance stress.Because of the nearly 600kg of thrust plate quality, the thrust plate of two kinds of schemes all need utilize bigger external force when the hydraulic cylinder shrinkage direction moves, and like hydraulic pressure or boom hoisting, cost is bigger.
The utility model content
The purpose of the utility model just provides with low cost, the good operability of a cover, satisfies the testing table thrust plate guide frame of test condition.
The utility model is for solving the problem on the original structure, and the concrete technical scheme of being implemented is:
But horizontal tunnel-liner rig for model test table top grave mound guiding thrust plate; Comprise the push pedal and test table top that are provided with the cross muscle; The below of two vertical cross muscle of push pedal is provided with " recessed " shape groove; Recessed " the shape slot welding be connected on the test table top on, the bottom is provided with roller, the vertical lower surface and the roller of cross muscle are tangent; Slide plate is the i-shaped beams structure, and the one of which end places in the skateboards slot of thrust plate, and tangent with the roller in the skateboards slot.Slide plate successively near near slide plate exceed a part.
It is the same that but all grave mounds guiding thrust plates are designed to, and forms by push pedal, slide plate and " recessed " shape chute, and push pedal and slide plate can mutual vertical movements in surface level; Slide plate can be moved by force direction along contiguous push pedal; Vertical lower surface place in " recessed " shape groove, be used for the guiding and the carrying of push pedal, and make push pedal with the test table top minim gap is arranged.During assembling all push pedal slide plates successively near near slide plate exceed a part.
Compared with prior art, the advantage of the utility model has:
" recessed " shape groove ensured each push pedal after receiving thrust hydraulic cylinder working direction accurately, and the deflection phenomenon can not appear, make country rock stressed evenly, ensured the accuracy that safety and test load.
The design of roller makes that the friction force that receives reduced when push pedal received the hydraulic cylinder promotion in " recessed " shape groove, reduces noise, moves push pedal after also making and becomes very easy, can simply can accomplish with hand push, and need not boom hoisting.
The design of table top and push pedal minim gap, the outer leakage quantity that had both guaranteed country rock have been eliminated the frictional resistance of existing structure push pedal with the test table top again in allowed limits, make that lower stress is even on the country rock, have ensured the accuracy that test loads.
The design of push pedal and slide plate has realized the mobile decoupling of push pedal and slide plate, and the vertical and horizontal motion is not disturbed mutually, loads accurately, and is safe and reliable.
Contacting between slide plate and country rock is complete plane contact, has eliminated three plane contact of every side in original scheme, has reduced the influence of push pedal to test.

Fig. 3 is the utility model structure cut-open view.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
A kind of embodiment of the utility model is like figure.It is the same that but all grave mounds guiding thrust plates are designed to, and forms by push pedal 1, slide plate 5 and " recessed " shape chute 6, and push pedal 1 and slide plate 5 can vertical movements each other in surface level; Slide plate 5 can be moved by force direction along contiguous push pedal 1; Vertical lower surface place in " recessed " shape groove 6, be used for the guiding and the carrying of push pedal 1, and make push pedal 1 and test table top that minim gap arranged.During assembling all push pedal 1 slide plates successively near near slide plate 5 exceed a part.
According to drawing with the utility model push pedal 1, cross muscle 2, skateboards slot 3 processing after, respective rollers 4 is installed, and skateboards slot is welded on cross muscle 2 front sides, load onto slide plate 5 from the skateboards slot side, front and back promote, and clamping stagnation do not occur and get final product.By drawing " recessed " shape groove 6 is machined, be symmetrically welded on the existing testing table table top, respective rollers 7 is installed, cross muscle 2 is placed in it and adjusts the position get final product.
