Problems solved by technology

However, the walking and transportation of the tire-type beam moving machine does not require rails, and its walking foundation needs to be handled separately, and it needs a large walking and turning space when using it.
In addition, the cost of the tire-type beam moving machine is expensive, and the prefabrication site needs to invest a high cost. It is generally used in large or even super large prefabrication sites

Embodiment 2

[0055] On the basis of Embodiment 1, the beam-moving trolley 6 includes a front trolley and a back trolley whose spacing can be adjusted along the extending direction of the orthogonal track 12, and the step b also includes: adjusting the front trolley and the back trolley according to the length of the transported prefabricated beam The distance of the car in the background. The beam moving trolley can adjust the spacing according to the size of the prefabricated beams by setting the front truck and the back truck, which improves the flexibility of beam transportation.

Embodiment 3

[0057] On the basis of Example 1, such as figure 2 As shown, the gantry crane is connected to the rails through outriggers 100, and the spacing of the orthogonal rails 12 is the same as that of the outriggers 100 on one side of the steering device 5 of the gantry crane. The supporting legs 100 of the gantry crane 4 are connected to the track through the traveling beam 90 and the traveling gear 30. The bottom of the leg 100 of the gantry crane 4, the travel gear 30 is driven by the travel motor 50 to move along the track, and the gantry crane steering device 5 includes a walking beam 90 connected with the track to lift the The jack 40 of walking beam 90. One side of the travel gear 30 is provided with an anti-collision device 60 . The traveling gear 30 is controllably locked to the beam making track 10 through the locking track device 20 . In this embodiment, by setting the traveling gear, the gantry crane can travel along the track. At the same time, by setting the jack, t...

Abstract

The embodiment of the invention discloses a novel broken-line-shaped beam transferring construction method and device in a track orthogonal type precast yard. The construction method includes the steps that a beam moving trolley is controlled to travel to orthogonal tracks intersecting with beam manufacturing tracks; a portal crane is controlled to perform beam lifting on a prefabricated beam in abeam manufacturing table base to go out of a groove through two lifting appliances, and the prefabricated beam is transported to the positions of the orthogonal tracks from the beam manufacturing table base; the prefabricated beam is installed and firmly fixed to the beam moving trolley, so that the portal crane and the beam moving trolley form an independent traveling system; due to a portal crane turning device, the portal crane is turned; the portal crane is adjusted to be in a no-load travelling state; the portal crane is turned through the portal crane turning device; and after the portal crane is controlled to lift up the prefabricated beam on the beam moving trolley through the two lifting appliances, moving to a beam storing table base along beam storing tracks to perform beam storing is performed. The novel broken-line-shaped beam transferring construction method and device in the track orthogonal type precast yard can achieve broken-line-shaped beam transferring in a track orthogonal type precast yard.

Description

technical field [0001] The embodiments of the present invention relate to the field of building technology, and in particular to a construction method and construction equipment for a new type of track-orthogonal prefabricated in-site zigzag transfer beam. Background technique [0002] Since the site selection of the prefabrication site is affected by the location of the bridge to be erected and the distribution of surrounding structures, it should be comprehensively determined from various aspects such as meeting the construction period and reasonable cost. Resources and other factors are limited. Therefore, for a horizontally arranged precast yard with a small site area and poor geological conditions, in order to meet the construction period requirements, improve the utilization rate of the precast site, and reduce the input cost of the precast site, the track-orthogonal precast site can be used. [0003] At present, in the track-orthogonal prefabrication field, the const...
