Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, this guard rail breakdown van anti-slip cramping apparatus, comprises contiguous block 1, upper connecting rod 4, two lower links 9 of frame 11, two and air spring 7; Contiguous block 1 is isosceles triangle shape, and contiguous block 1 drift angle end is provided with bearing pin 2; Upper connecting rod 4 is straight-arm structure, lower link 9 is structure of cranking arm, top of cranking arm is divided into linking arm 3, bottom of cranking arm is divided into jig arm 5, and on two, the upper end of connecting rod 4 is hinged with a base angle end of contiguous block 1 respectively, the lower end of upper connecting rod 4 and the upper end thereof of linking arm 3, frame 11 has two, lower link 9 is positioned in the middle of two frames 11, and two frame 11 medial surface two ends are hinged with a lower link 9 respectively, and pin joint is at lower link 9 bending part; Offer stopper slot inside jig arm 5, clamping fixture head 10 is threaded connection and is arranged in stopper slot, facilitates the replacing of clamping fixture head 10, is provided with rubber pad outside clamping fixture head 10, and when rubber pad contacts with steel, friction factor is large, contributes to anti-skidding; Air spring 7 has two, and the two ends of each air spring 7 are hinged with the linking arm 3 of the same side, frame 11 respectively.
Conveniently staff is to operation of the present utility model, sets up handle 6, and handle 6 is arranged on lower link 9; According to field experience, in order to increase work efficiency as much as possible, reducing the amplitude of accommodation, by setting up upper limit position block 31 and lower position block 32, limiting the minimum and maximum angular range of fixture, upper limit position block 31 is arranged on the inner side of linking arm 3, lower position block 32 is arranged on the outside of linking arm 3, and the limited block position that two linking arms 3 are arranged is corresponding, as shown in Figure 2, when lower position block 32 contacts with frame 11, fixture has maximum grip angle; As shown in Figure 3, when the upper limit position block 31 on two lower links 9 contacts with each other, fixture has minimum grip angle.
When fixture is not freely placed by External Force Acting, under the effect of air spring 7, lower link 9 rotates around the pivot point with frame 11, and clamping fixture head 10 will be in the state of minimum grip angle, before fixture being clipped in guardrail pile surface, handle 6 need be moved downwards, lower link 9 rotates around the pivot point with frame 11, gripping angle between clamping fixture head 10 is increased, as shown in Figure 4, frame 11 is placed on above guardrail pile 8, release handle 6 rear jig chuck 10 clamps guardrail pile 8 under air spring 7 acts on, the bottom of guardrail pile 8 deeply below ground, clamping fixture head 10 is clamped in the top of guardrail pile 8, the fixed pulley 13 walked around by wire rope 14 bottom hydraulic hammer mounting bracket 12 is connected to bearing pin 2 place, hydraulic hammer mounting bracket 12 can move straight up along the fixed guide of guard rail breakdown van, tense wire rope 14 also produces pile pulling power upwards at bearing pin 2 place, pile pulling power is larger, normal pressure between guardrail pile 8 and clamping fixture head 10 and frictional force also can increase accordingly, the frictional force of guardrail pile 8 pairs of clamping fixture heads 10 can be made to be greater than pile pulling power all the time by the design of clamp structure, thus realize the skidproof effect of fixture.
At present, the pile pulling operation of guardrail repairing operation is mainly divided into two kinds, one be directly adopt vertical telescopic oil cylinder upwards action realize pile pulling, another kind adopts vertical telescopic oil cylinder upwards action and hydraulic vibration driver vibration acting in conjunction realize pile pulling.Vibration due to hydraulic hammer can make the adhesion factor between guardrail pile and ground reduce, reduce the frictional force between guardrail pile and ground, make pile pulling more easy, so when cannot directly carry out pile pulling by first method, need to adopt second method to carry out pile pulling operation.But, when adopting second method to carry out pile pulling, because the piston on vibrating hammer in vibration processes is doing reciprocal low frequency vibration, can impact force be produced when piston stretches out time, but when piston retracts, impact force is zero.Due to the effect of air spring 7, when there is no External Force Acting, air spring 7 provides pretightning force can to clamping fixture head 10, effectively prevent in vibration processes when occurring that intermittent pile pulling power is zero, the phenomenon that clamping fixture head 10 departs from from guardrail pile surface, makes the utility model can be applied to above two kinds of pile pulling modes.
The damage guardrail pile will extracted in repairing operation process, its cross section scarcely for another example new pile is equally standard specification cross section, this clamp angle excursion is large, can meet the distortion of guardrail pile after the change of the grip dimensions that actual pile changes of section causes and clamp.
The rail pile column section specification that Domestic Road Maintenance department commonly uses mainly contains two kinds: diameter 114mm and diameter 140mm.Can be realized the clamp operation to different size pile by the clamping fixture head 10 changing different size, versatility is good, and it is convenient to change, and greatly can promote the efficiency of guardrail repairing operation.
