Embodiment 1

[0042] The embodiment of the present invention provides a construction method for falling beams at oblique angles within the span of a single-gantry crane. The construction method is carried out using construction equipment, such as Figure 1-2 As shown, the construction equipment includes a double spreader gantry crane, a crane track, a rotatable spreader 3, a fixed end spreader 4 and a beam carriage, and the double spreader gantry crane moves along the crane track , the beam-carrying cannon car includes a front car 1 of a beam-carrying cannon and a rear car 2 of a beam-carrying cannon, the front car 1 of the beam-carrying cannon and the rear car 2 of the beam-carrying cannon are arranged at intervals and the loading operation of the beam-carrying cannon When the total length of the profile is greater than the span of the double spreader gantry crane, the rotatable spreader 3 and the fixed end spreader 4 are respectively suspended on both sides of the double spreader gantry cra...

Embodiment 2

[0051] On the basis of Example 1, such as Figure 1-2 As shown, the double spreader gantry crane includes a gantry crane girder 7, two gantry crane flexible outriggers 12 connected under the two ends of the gantry crane girder 7 and a Two hoisting trolleys 6 above the beam 7 that can translate along the main beam 7 of the gantry crane, one of the hoisting trolleys 6 is connected with the rotatable spreader 3 located below and controls the rotatable spreader 3 The spreader 3 moves horizontally, moves up and down and rotates, and the other lifting trolley 6 is connected with the fixed end spreader 4 located below and controls the fixed end spreader 4 to move horizontally and move up and down. The crane track includes a steel rail 10 and a track foundation 11 arranged below the steel rail 10 , and the two flexible legs 12 of the gantry crane can translate along the steel rail 10 . A pedestrian ladder 13 is arranged on the flexible outrigger 12 of the gantry crane. The rotatable ...

Embodiment 3

[0053] On the basis of Example 1, such as Figure 1-2 As shown, the front carriage 1 of the beam-transporting artillery cart and the rear carriage 2 of the beam-transporting artillery carriage are respectively composed of a car body assembly, a bogie assembly, a braking device, a driving device, and a supporting and fixing device. The braking device and the driving device are arranged in the vehicle body assembly, and the bogie assembly and the supporting and fixing device are arranged on the vehicle body assembly. The bogie assembly is connected to the car body assembly through the pin shaft vertically arranged in the axial direction, and the friction pair is formed between the bottom through the wear plate and the car body assembly, and an oblique support or a fixed frame is arranged on the top, when the beam is transported When the gun carriage turns, the bogie assembly can form a relative rotation with the vehicle body. The beam transporting artillery cart is a tire-type b...

Abstract

The embodiment of the invention discloses a single-portal crane span oblique beam falling construction method and construction equipment. The construction method comprises the following steps that beam-transporting carriers are conveyed to the portion between crane rails; a portal crane is operated to lift a prefabricated U-type beam from a beam making pedestal; the portal crane is operated to move along the crane rails, and a fixed end lifting apparatus is located above the rear beam-transporting carrier; the portal crane is operated to make the fixed end lifting apparatus separated from oneend of the prefabricated U-type beam, and the fixed end lifting apparatus is lifted; the portal crane is operated to move so that a rotary lifting apparatus and the other end of the prefabricated U-type beam can be located above the front beam-transporting carrier; and the rotary lifting apparatus is operated to be separated from the other end of the prefabricated U-type beam, and the rotary lifting apparatus is lifted. According to the method, the rotary lifting apparatus is exquisitely used for rotating a beam body in the conveying process, so that the beam-transporting carriers are driven away from the beam falling area after beam falling conveniently, and the operation efficiency is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of geotechnical construction, in particular to a single-gantry crane construction method and construction equipment for dropping beams at oblique angles within the span. Background technique [0002] In the construction of transporting and erecting beams, gantry cranes and beam-carrying cannons are often used as process equipment for reversing prefabricated beams. Generally, gantry cranes are used to lift beams and move forward to the top of the beam-carrying cannons parked perpendicular to the track. , the prefabricated beams are placed on the beam transporting brackets of the front car and the rear car of the beam transporting gun car. However, engineering design beams are often complex and changeable, with different lengths. Limited by the large-scale equipment leasing market, the specifications and sizes cannot be flexible and comprehensive. Therefore, it often happens that the ...
