Abstract
The utility model discloses a front landing leg lifting device for a bridge girder erection machine. The front landing leg lifting device for the bridge girder erection machine comprises two front landing legs, a cross beam and a hydraulic cylinder, wherein the hydraulic cylinder is arranged on a base of the bridge girder erection machine, a piston rod of the hydraulic cylinder is connected with the cross beam, pin holes are formed in the two ends of the cross beam respectively, and the two ends of the cross beam are installed on the two front landing legs respectively through pin shafts. The front landing leg lifting device for the bridge girder erection machine has the advantages that working safety can be improved, the erection adaptive range under the longitudinal slope condition is wider, stability is improved, erection under different slope conditions can be achieved, and operation is convenient to achieve.
Description
Technical field
The utility model relates to lifting gear, relates in particular to a kind of front outrigger for bridge girder erection machine lifting gear.
Background technology
Development along with high-speed railway and highway, the problem of setting up of the prefabricated whole opening box girder of large-tonnage is further outstanding, various types of large box girder Bridge Erectors have been there are both at home and abroad, in the past the lifting of Bridge Erector often adopt the disconnected formula column of joint to adjust the gradient of ground, to setting up of different gradient, require compliance poor, the erection construction scope under longitudinal grade condition is little, poor stability, and total quality is larger, to operating personnel, makes troubles.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure with regard to being in order to address the above problem, convenient a kind of front outrigger for bridge girder erection machine lifting gear of adjusting ground angle of inclination.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises two front leg struts, crossbeam and hydraulic cylinders, described hydraulic cylinder is arranged on bridge machine base, the piston rod of described hydraulic cylinder is connected with described crossbeam, and the two ends of described crossbeam are provided with pin-and-hole, and the two ends of described crossbeam are installed on two described front leg struts by bearing pin respectively.
The beneficial effects of the utility model are:
The utility model can strengthen operational security, and the erection construction accommodation under longitudinal grade condition is larger, has improved stability, meets the different gradients and sets up, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-bridge machine base, 2-front leg strut, 3-crossbeam, 4-hydraulic cylinder, 5-snib, 6-latch, 7-groove, 8-piston rod.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model comprises two front leg struts 2, hydraulic cylinder 4 and crossbeam 3, described hydraulic cylinder 4 is arranged on bridge machine base 1, the piston rod of described hydraulic cylinder 4 is connected with described crossbeam 3, the two ends of described crossbeam 3 are provided with pin-and-hole, the two ends of described crossbeam 3 are installed on two described front leg struts 2 by bearing pin 6 respectively, on bridge machine base 1, be provided with and can hold the up and down groove of front leg strut 27, front leg strut 2 is arranged in the groove 7 of bridge machine 1, is provided with the snib 5 being fixedly connected with front leg strut 2 on bridge machine 1.
Operating principle of the present utility model is as follows: when needs set up highway, bridge machine base 1 plays main support effect, piston rod is under the effect of hydraulic cylinder 4, crossbeam 3 is applied to downward power, crossbeam 3 drives crossbeam 3 to do axially-movable, and double hydraulic cylinder 4 can make the stressed more even of crossbeam 4 simultaneously, reaches 3 static(al) equilibriums, by adjust front leg strut 2 rail level height, thereby realize the process of lifting.
