Problems solved by technology
[0002] In the prior art, during the transportation of the box girder, there are only beam transport vehicles and beam trolleys. This structure has the following disadvantages: the height adjustment range of the box girder to be transported is relatively small, and the platform adjustment range of the beam transport vehicle is generally ±300mm. The trolley cannot be adjusted. If there is a situation where the clearance height is relatively low, such as passing through a low tunnel, etc., it cannot pass through. It is necessary to use a beam transporter with a lower body to transport it first, and then hoist the box girder on this beam transporter. superior
Therefore, this structure is only suitable for open roads with low height requirements.

Embodiment Construction
[0017] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0018] Refer to attached figure 1 Shown: a lifting device for a beam transporting carriage box girder, including: a connecting seat 1, a sleeve 2, a jacking cylinder 3, and a hydraulic system 8. The sleeve 2 is installed in the connecting seat 1; the upper and lower ends of the jacking cylinder 3 are symmetrically provided with connecting pins 5 and baffles 6, and the upper connecting pins 5 and baffles 6 fix the jacking cylinder 3 and the sleeve 2, The connecting pin 5 and the baffle plate 6 at the lower part fix the jacking cylinder 3 and the connecting seat 1, and make the connecting seat 1 and the sleeve 2 be connected as a whole through the jacking cylinder 3. The hydraulic system 8 is respectively arranged on the jacking cylinder 3 symmetrically up and down, and is used to control the work of the jacking cylinder 3 . Two symmetrical limit pi...

The invention relates to a box girder lifting device of a girder transport carriage. The device comprises a connection seat, a sleeve barrel, a jacking oil cylinder and a hydraulic system, wherein the sleeve barrel is arranged in the connection seat; the upper end and the lower end of the jacking oil cylinder are symmetrically and respectively provided with a connection pin and a baffle plate; the connection pin and the baffle plate on the upper part are used for fixing the jacking oil cylinder with the sleeve barrel, the connection pin and the baffle plate on the lower part are used for fixing the jacking oil cylinder with the connection seat, and the connection seat and the sleeve barrel are connected into a whole through the jacking oil cylinder; and the jacking oil cylinder is controlled by the hydraulic system to work. The device effectively lowers the height of a finished vehicle and meets the requirement on clearance height when the vehicle passes through a tunnel with a heavy load. Meanwhile, the device has the advantages of convenient and simple operation, reduction of a step of box girder transport by changing vehicles, improved working efficiency simple structure, easy operation and lower manufacturing and maintaining cost.
