Description
Technical field
The utility model relates to a kind of bridge vertical shift hydraulic means, is applied in bridge construction.
Background technology
In railroad bridge construction; often can cannot construct because of many reasons bridge original position; therefore bridge rotating, vertical shift, traversing technology are widely used; vertical shift can be more utilize existing bridge pier; reduce temporary supporting facility, when possessing vertical shift execution conditions, preferentially selected, vertical shift bridge now adopts continuous very heavy cylinder and moves beam dolly; this process need is established and is moved beam orbit, and construction cost is higher.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple in structure and railless bridge vertical shift hydraulic means.
A kind of bridge vertical shift hydraulic means, comprise vertical hydraulic cylinder, it is characterized in that: the pallet that a square shape is set on the piston rod of described vertical hydraulic cylinder, the side of vertical hydraulic cylinder is provided with longitudinal hydraulic cylinder, longitudinally on the piston rod of hydraulic cylinder, connect a lifting apparatus, the height of lifting apparatus is between the minimum constructive height and maximum height of vertical hydraulic cylinder lifting pallet, bottom at vertical hydraulic cylinder and longitudinal hydraulic cylinder is provided with rectangle base, and the base longitudinally piston rod movement direction of hydraulic cylinder stretches out.
The utility model is the contact area of increase with bridge, the pallet of a square shape is set on the piston rod of vertical hydraulic cylinder, for ease of realizing, vertically move, side at vertical hydraulic cylinder is provided with longitudinal hydraulic cylinder, for ease of realizing, vertically move continuously, longitudinally on the piston rod of hydraulic cylinder, connect a lifting apparatus, and the height of lifting apparatus is between the minimum constructive height and maximum height of vertical hydraulic cylinder lifting pallet, be convenient to carry mutually bridge, and be provided with rectangle base in the bottom of vertical hydraulic cylinder and longitudinal hydraulic cylinder, the base longitudinally piston rod movement direction of hydraulic cylinder stretches out.
For reducing friction, between described base and lifting apparatus, be provided with the slide block of polytetrafluoroethylene (PTFE) material.
While using the utility model cylinder to push away bridge, first vertical hydraulic cylinder lifts bridge, then vertical hydraulic cylinder falls after rise bridge is placed on the lifting apparatus of longitudinal hydraulic cylinder drive, while then driving bridge level to move to range by longitudinal hydraulic cylinder, vertical hydraulic cylinder is lifted bridge again, the lifting apparatus that longitudinally hydraulic cylinder drives returns original position, and then bridge is placed on the lifting apparatus of longitudinal hydraulic cylinder drive, and then drive bridge horizontal movement by longitudinal hydraulic cylinder, above-mentioned steps iterative cycles, until complete bridge vertical shift operation.
The utility model is simple in structure, and without laying track, easy to operate, continuous movement, repeatedly moves and can realize the movement that surmounts longitudinal hydraulic cylinder range, and economic benefit is obvious.

In figure 1, vertical hydraulic cylinder, 2, longitudinal hydraulic cylinder, 3, piston rod, 4, lifting apparatus, 5 bases, 6 slide blocks, 7, pallet.
The specific embodiment
Below by embodiment, also by reference to the accompanying drawings the utility model is described further: this embodiment comprises vertical hydraulic cylinder 1, it is characterized in that: the pallet 7 that a square shape is set on the piston rod of described vertical hydraulic cylinder 1, the side of vertical hydraulic cylinder is provided with longitudinal hydraulic cylinder 2, longitudinally on the piston rod of hydraulic cylinder, connect a lifting apparatus 4, the height of lifting apparatus 4 is between the minimum constructive height and maximum height of vertical hydraulic cylinder 1 lifting pallet 7, bottom at vertical hydraulic cylinder 1 and longitudinal hydraulic cylinder 2 is provided with rectangle base 5, base 5 longitudinally piston rod 3 directions of motion of hydraulic cylinder stretches out, between described base 5 and lifting apparatus 4, be provided with the slide block 6 of polytetrafluoroethylene (PTFE) material.
As shown in accompanying drawing 1 or accompanying drawing 2, the utility model is comprised of one group of lifting apparatus 4 that is fixed on base 5 vertical hydraulic cylinder 1 and longitudinally drives to pressure-bearing cylinder 2, vertical hydraulic cylinder 1 plays bridge cylinder, longitudinal hydraulic cylinder 2 returns, the slow return bridge of vertical hydraulic cylinder 1 falls within on the drive lifting apparatus 4 of longitudinal hydraulic cylinder, longitudinally hydraulic cylinder 2 drives bridge to be moved horizontally to after range, vertical hydraulic cylinder 2 is jack-up again, longitudinal hydraulic cylinder 2 returns, and then bridge is placed on to horizontal movement on lifting apparatus 4, above-mentioned action iterative cycles, complete bridge vertical shift operation, this process can be organized the utility model by computer control more, realize synchronization job.
As shown in Figure 3, bridge is established nose girder to arrangement diagram while utilizing the utility model cylinder to push away bridge, and 1 or 2 group of bridge vertical shift hydraulic means of the present utility model is all set on each bridge pier, and base 5 is secured by bolts on bridge pier pre-embedded steel slab.
Other parts of the present utility model adopt known technology, do not repeat them here.
