Prefabricated T beam transferring trolley

Abstract

The invention relates to building construction equipment, in particular to an omnidirectional chain wheel type beam transferring trolley and a construction method of a prefabricated T beam. The beam transferring trolley comprises a walking mechanism, a jacking mechanism arranged on the walking mechanism, and a T beam clamping device connected with the jacking mechanism and used for clamping the prefabricated T beam, wherein the cross section of the T beam clamping device is shaped as a Chinese character ao, the T beam clamping device mainly comprises a trimming beam bottom plate and two trolley brackets symmetrically arranged at two sides of the trimming beam bottom plate, the prefabricated T beam is fixed in a groove of the T beam clamping device, the trolley brackets comprise a verticalsupporting rod and a triangular bracket fixedly connected with the outer side of the vertical supporting rod, and the triangular bracket is supported on the jacking mechanism. The invention has the advantages that the prefabricated T beam is reliably fixed through a special T beam clamping device, which avoids inclining or turning during the transferring; and the beam rising action is stable, theadaptability is strong, the requirements on the foundation and the base are low, and the adaptability to the field conditions is strong.

Description

technical field [0001] The invention relates to building construction equipment, in particular to a prefabricated T-beam omnidirectional sprocket-type beam-moving trolley and a construction method thereof. Background technique [0002] Beam moving trolley is an important equipment for moving and transporting prefabricated reinforced concrete beams in the beam yard. At present, large-ton displacement beam trolleys are mostly developed for the movement and transportation of high-speed railway box girders. Two basic schemes are usually adopted. One is to use a traverse trolley to jack up the box girder from bottom to top and then move laterally. Sliding trolley plus special beam-moving slideway or wheel-rail type traversing trolley (divided into mechanical transmission and hydraulic push-push type) can be used; the second is to use a beam handling machine to lift from top to bottom, that is, the lifting beam According to the plan, the beam handling machine is divided into tir...

AI Technical Summary

Problems solved by technology

The lifting and moving beam equipment can realize double-layer beam storage and beam moving and loading at any position. The walkway covers a large area, the processing cycle of the equipment is long, the purchase cost, use cost and maintenance cost are high, and the operation is more complicated.

[0004] In addition, due to the difference in cross-sectional shape between the box girder and the T girder, if the long and irregular T girder is placed directly on the trolley for transportation, the T girder will inevitably overturn, so the box girder beam moving trolley cannot be used. For moving T-beam
