[0002] After the prefabrication of the track beam is completed, it needs to be spliced with beams and columns. During splicing, the prefabricated track beam is hoisted to the designated position by a crane. After the track beam is in place, the track beam needs to be fine-tuned during splicing, generally The jack is used to fine-tune the track beam with the ejector pin. The strength of the ejector pin in the prior art is low. Due to the high gravity of the track beam itself, the reuse rate of the ejector pin is low, resulting in waste of resources, and the position of the adjustment hole reserved for the track beam Uncertain, when the position of the adjustment hole deviates, the jack power assembly needs to be shifted as a whole, and the work efficiency is poor

The invention discloses a pin-lift device for a track beam. The device comprises a force plate and a push plate arranged in parallel, a set of first fixing holes are formed in one side of the force plate, second fixing holes are formed in one side of the push plate, the first fixing holes are formed in one-to-one correspondence with the second fixing holes, connecting rods are fixedly connected between every two corresponding first fixing hole and the second fixing hole, reinforcing sleeves evenly sleeve the outsides of the connecting rods, a straight circular through groove is formed in one side of the push plate, a substrate is arranged on one side of the push plate, a mandril is cooperatively connected with the center of the substrate, the mandril passes through the straight circular through groove and protrudes to the outside of the push plate, and a fixing member for fixing the substrate to one side of the push plate is arranged on the mandril. The device has the advantages that apin-lift structure in the prior art is changed, the strength is high, the device is not easily damaged, and can be repeatedly used, the position of the mandril can be adjusted, and when the positionof a prepared adjustment hole of the track beam is deviated, the position of the mandril in the device is adjusted.
Description
technical field [0001] The invention relates to the technical field of rail beam manufacturing, in particular to a jacking device for a rail beam. Background technique [0002] After the prefabrication of the track beam is completed, it needs to be spliced with beams and columns. During the splicing, the prefabricated track beam is hoisted to the designated position by a crane. After the track beam is in place, the track beam needs to be fine-tuned during splicing, generally The jack is used to fine-tune the track beam with the ejector pin. The strength of the ejector pin in the prior art is low. Due to the high gravity of the track beam itself, the reuse rate of the ejector pin is low, resulting in waste of resources, and the position of the adjustment hole reserved for the track beam Indefinitely, when the position of the adjustment hole deviates, the jack power assembly needs to be shifted as a whole, and the working efficiency is poor.
