Abstract
The utility model relates to a case roof beam sideslip thrustor, including dull and stereotyped dolly, dull and stereotyped dolly bottom is equipped with the gyro wheel, and the top is equipped with the support jack, and the gyro wheel of dull and stereotyped dolly is located one and slides on the track, is equipped with a top and pushes away the jack on the track that slides, and top pushes away jack one end and fixed clamp rail ware on the track that slides and passes through the round pin hub connection, and the other end passes through the round pin hub connection with the rear end of dull and stereotype. The utility model is used for the case roof beam erects on the pier, hangs the case roof beam earlier on putting the travelling car, then realizes the accurate adjustment of case roof beam position through the removal that pushes away the dolly, can improve the case roof beam and erect efficiency of construction, shortens construction cycle.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a thereby carry out the thrustor that lateral displacement made the case roof beam accurately take one's place to the case roof beam when installing the case roof beam on the pier is related to.
Background
The upper structure of the highway and railway bridges mostly adopts prestressed concrete T-shaped or box-shaped beams, and the box beams are usually prefabricated in a beam yard and then transported to the site for erection. On-site erection is usually carried out by adopting hoisting equipment such as a bridge girder erection machine and a cable crane, and under the conditions of local widening, curve section and the like of a line route, the beam can not be accurately positioned once when falling, secondary transverse movement is often needed, but the construction environment restriction such as transverse clearance, width restriction and the like is adopted, and the difficulty of secondary transverse movement of the box girder by large-scale equipment such as the bridge girder erection machine and the cable crane is high, so that a large amount of working hours are consumed, and the construction progress is influenced.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a case roof beam sideslip thrustor is provided for case roof beam sideslip speed improves the efficiency of construction.
The technical scheme of the utility model as follows:
the utility model provides a case roof beam sideslip thrustor which characterized in that: the flat trolley comprises a frame, wherein the bottom of the frame is provided with a roller, the top of the frame is provided with a supporting jack, the roller of the flat trolley is positioned on a sliding track, the sliding track is provided with a pushing jack, one end of the pushing jack is connected with a rail clamping device on the fixed sliding track through a pin shaft, and the other end of the pushing jack is connected with the rear end of the flat trolley through a pin shaft.
The utility model discloses simple structure hangs the case roof beam earlier on the travelling car, then realizes the accurate adjustment of case roof beam position through the top dolly that pushes away, convenient operation, and the security is high, can improve the case roof beam greatly and erect efficiency of construction to shorten construction cycle. The utility model discloses can set up the dolly number according to the roof beam body size, the suitability is strong.
Drawings
Fig. 1 is a schematic side view of the present invention;
fig. 2 is a schematic view of the usage state of the present invention.
Detailed Description
As shown in fig. 1, the utility model discloses a flat car, flat car includes frame 1, and frame 1 bottom is equipped with gyro wheel 2, and the frame top is equipped with support jack 3, and the gyro wheel 2 of flat car is located one and slides track 4, it pushes away jack 5 to be equipped with one on the track 4 that slides, push away 5 one end of jack and the fixed rail clamping device 6 that slides on the track through the round pin hub connection, the other end and flat car frame 1's rear end through the round pin hub connection.
The idler wheels 2 of the flat car can adopt two-axis four-wheel.
The utility model discloses can link to each other two or more dollies according to the width of case roof beam, constitute a platform truck group. In the embodiment shown in fig. 1, there are two flat trolleys, wherein the rear end of the frame 1 of one flat trolley is connected with the pushing jack 5, the front end of the frame is welded with the rear end of the other flat trolley through a connecting rod 7, the rollers of the two flat trolleys are located on the same sliding track 4, and the top of each flat trolley is provided with a supporting jack 3.
The utility model is used for during the construction, install case roof beam sideslip thrustor simultaneously on two piers at support case roof beam both ends.
As shown in figure 2, the sliding rail 4 is transversely fixed at the top of the pier 8 in a bridging direction, the flat car is arranged on the sliding rail, and the pushing jack 5 is connected. The piston of the supporting jack 3 extends to be higher than the bridge support 9, the box girder 10 is lifted above the bridge pier by a bridge girder erection machine or a cable crane and then falls onto the supporting jack 3, then the pushing jack 5 is started, the pushing flat trolley moves along the sliding track, transverse movement is carried out according to the designed installation position of the box girder, the supporting jack 3 contracts after the box girder moves in place, and the box girder 10 falls onto the bridge support.
