Description

The paver Wheel gripping device

The utility model relates to road construction equipment, especially relates to the paver Wheel gripping device.

At present, in the domestic road construction, paver is by the trailing wheel of the pushing tow roller contact dummy car of self, pushing away the dummy car walking, dummy car tilts to pour in the reception hopper of paver with material spreader simultaneously, by the paver paving concrete pavement, because only for the contacting of pushing tow roller get in touch between paver and the dummy car this moment, be provided with and tighten up linkage, paver and dummy car are not synchronous operation, have influenced at the uniform velocity advancing of paver on the one hand, ripple takes place in road surface easily that come out in the shop, dummy car is when the paver discharging on the other hand, takes place easily to leak material, influences that paver steadily advances and the pavement spread quality.

The purpose of this utility model provides a kind of Wheel gripping device, but folding with convenience ground dummy car and paver are closely coupled together, the dummy car and the function synchronization line that paves are sailed.

For achieving the above object, the main body of this Wheel gripping device is the crossbeam of a band cavity, the crossbeam front surface is provided with and the corresponding push roller of dummy car trailing wheel, in the cavity of crossbeam, be provided with two by the fixing symmetrical hydraulic cylinder of terminal pad, one end of expansion link and slide bar is fastening is connected as a single entity, the other end termination of slide bar in crossbeam is provided with position-limitting pin, it is corresponding that pin and big beam sides have stopper slot, the inboard of embracing the wheel arm is equipped with the limit roller, embrace wheel arm front end and be fitted with folding shape arm, the other end of folding shape arm is provided with embraces supporting-point roller.Adopt the utility model, when the needs dummy car travels with paver, hydraulic pressure folding control system is shunk expansion link, drive and embrace wheel arm and folding shape arm, make and embrace the rear wheel rotation net that supporting-point roller is held dummy car tightly, the limit roller can be adjacent to the rear tyre outside of dummy car, dummy car and paver close-coupled together, the trailing wheel of the dummy car of the push roller of Wheel gripping device contact simultaneously, push away dummy car by paver and advancing, realizing travelling synchronously of dummy car and paver, can effectively keep at the uniform velocity travelling of paver, also be difficult for the material phenomenon takes place to leak, guarantee the construction quality on road surface.

Be that embodiment elaborates to the utility model below with the accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

In Fig. 1, crossbeam 1 is made by seamless steel pipe, the back of crossbeam is welded with iron plate, have screw on the iron plate, can be fixed on crossbeam 1 on the paver, the front of crossbeam 1 is equipped with the push roller 11,12 of two symmetries, and its position is corresponding with the trailing wheel of dummy car, and push roller adopts the general carrying roller of market sale to get final product.The hydraulic cylinder 3,4 that two symmetries are arranged in the crossbeam 1, hydraulic cylinder 3,4 adopts the general hydraulic cylinder of market sale, and hydraulic cylinder 3,4 is fixing by terminal pad 2.Slide bar 5,6 adopts seamless steel pipe to make, and the end termination of slide bar 5,6 in crossbeam 1 has position-limitting pin 51,61, and a corresponding side at crossbeam 1 has stopper slot 15,16, and it is also spacing that slide bar 5,6 is tried to shirk responsibility.An end and an end of hydraulic cylinder expansion link 31,41 steel plate 52,62 welding of by the outside wearing projection of slide bar 5,6 outside crossbeam 1.Even be associated in together, simultaneously, on projection, be equipped with steel bushing 53,63, embrace the rear end and the steel bushing welding of wheel arm 7,8.The inboard of embracing wheel arm 7,8 is welded with limit roller 71,78, and its position is corresponding with the rear tyre outside of dummy car, during use, can be close to the dummy car rear tyre outside, and limit roller 71,81 adopts the general carrying roller of market sale to get final product.Embrace wheel arm 7,8 front ends and have folding shape arm 9,10, a folding shape arm 9,10 and an armful wheel arm 7,8 can weld, preferably movable connects, promptly have the edge at the front end of embracing wheel arm 7,8, the part of folding shape arm 9,10 is inserted the hole, utilize the screw 72,82 on the roof of hole to tighten, can regulate the lateral attitude of folding shape arm 9,10 as required like this.The other end of folding shape arm 9,10 is equipped with embraces supporting-point roller 91,101, embrace supporting-point roller 91,101 and the corresponding usefulness of dummy car rear wheel rotation net, can tightly embrace the rear wheel rotation net of dummy car during use, embrace supporting-point roller 91,101 and can make by oneself, be the round roller of a band of car inner chamber, inner chamber is loaded onto oscillating bearing and is got final product.
