Construction method for horizontal moving beam of double-track trolley

A double-track, trolley technology, applied in the direction of manufacturing tools, ceramic molding machines, etc., can solve the problems of restricting the reverse transportation and loading of prefabricated beams, affecting the production capacity of prefabricated beam factories, and slow running speed, saving labor and T beams. The traverse process is safe and the effect of reducing displacement

Problems solved by technology

And because the traveling speed of the gantry crane is slow after loading, the more longitudinal pedestals, the longer the traveling distance of the gantry crane, which restricts the unloading and loading of prefabricated beams, and ultimately affects the production capacity of prefabricated beam factories

Abstract

The invention relates to a moving method for a T beam of a prefabricated beam factory, in particular to a construction method for a horizontal moving beam of a double-track trolley. The invention adopts two beam-moving trolleys to move beams in a horizontal direction along the track. Jacks are arranged the beam-moving trolleys, the jacks have an automatic lifting function, firstly, the trolleys are moved directly below the T beam in a longitudinal beam storage area, the jacks are started to hold the T beam, so that the T beam breaks away from an original beam storage pedestal. After the reinforcement and stability, the trolleys pull the T beam to move along a horizontal track to a horizontal beam storage area. Then the jacks are depressurized, the T beam is in place, and the trolleys return empty. The construction method realizes the horizontal beam moving, overcomes the problems of the T-beam stability during the cross construction and the beam moving process of the longitudinal andhorizontal tracks, fully utilizes the site width of a precast beam factory, and improves the beam storage capacity of the precast beam factory.

Description

technical field [0001] The invention relates to a method for moving a T-beam in a prefabricated beam factory, in particular to a construction method for laterally moving a beam by a double-track trolley. Background technique [0002] The original planning of the railway prefabricated girder factory is vertical vertical girder storage, that is, vertical gantry crane tracks are set in the prefabricated girder factory, and several girder storage pedestals are constructed at a certain distance between the longitudinal gantry crane tracks, and the T beams are stored on the beam storage pedestals. The beam storage pedestal can only be installed vertically along the longitudinal gantry crane track. The length of the longitudinal gantry crane track determines the beam storage capacity of the prefabricated beam factory. The vertical vertical beam storage cannot make full use of the site width of the prefabricated beam factory. And because the traveling speed of the gantry crane is re...
