Abstract
The utility model discloses a front bracket provided with four pillars and used in a bridge girder erection machine. The front bracket comprises wheel boxes arranged on a front branch transversely-sliding track and a support beam arranged on the wheel boxes, wherein two telescopic pillars are respectively arranged on two sides at the upper part of the support beam; a plurality of adjusting holes are vertically formed on the lateral surfaces of the telescopic pillars respectively; telescopic oil cylinders are respectively arranged between the telescopic pillars; the cylinder body or a piston rod at one end of the telescopic oil cylinder is connected with the adjusting hole via a pin shaft; and the cylinder body or the piston rod at the other end of the telescopic oil cylinder is connected with a girder tray of the bridge girder erection machine. The front bracket provided by the utility model has the advantages that the plurality of adjusting holes are vertically formed on the lateral surfaces of the telescopic pillars, so that the height of the telescopic oil cylinders can be conveniently adjusted; and the two telescopic pillars are respectively arranged on the two sides of the supporting beam, so that the intensity is greatly enhanced and the use safety is improved. When the front bracket is used in the bridge girder erection, the last hole can climb an abutment to reach the appropriate position at one time, so that the front bracket is suitable for the longitudinal slope bridge erection with the slope not larger than 5%.
Description
Technical field
The utility model relates to the bridge construction mechanical field, especially relates to a kind of four pillar fore-stocks that are used to the machine of building bridge.
Background technology
Present bridge formation machine fore-stock is two telescopic mast structures, is very limited when Height Adjustment, and intensity and safety also are difficult to guarantee.
Summary of the invention
The utility model purpose is to provide a kind of and convenient regulates the telescopic oil cylinder height, and the four pillar fore-stocks that are used to the machine of building bridge of intensity height, safety and stability.
For achieving the above object, the utility model can be taked following technical proposals:
The four pillar fore-stocks that are used to the machine of building bridge described in the utility model, comprise the roller box on the cross moving track before placing, with the supporting beam that places on the described roller box, be respectively arranged with two telescopic masts in both sides, described brace summer top, vertically offer a plurality of adjustment holes in described telescopic mast side respectively along it, between described telescopic mast and telescopic mast, be respectively arranged with telescopic oil cylinder, the cylinder body of described telescopic oil cylinder one end or piston rod are connected with described adjustment hole by bearing pin, and the piston rod of the telescopic oil cylinder other end or cylinder body are connected with the girder pallet of bridge formation machine.
The utility model advantage is that the telescopic mast side along its a plurality of adjustment holes of vertically offering, can regulate the height of telescopic oil cylinder easily; Both sides are respectively arranged with two telescopic masts on the brace summer, have increased intensity greatly, have improved the safety of using.When setting a roof beam in place, last hole via hole climbs that abutment is disposable to put in place, is suitable for reaching≤the setting up of 5% longitudinal gradient bridge.
