Problems solved by technology

The weight of the hoisting components is between 15-150 tons. According to the conventional construction method, large-scale hoisting equipment is used to hoist under the dam. The hoisting time is long, and the cost of extra-large hoisting equipment is very high. Installation and construction cannot be carried out in the rainy season.

Embodiment Construction

[0032] Such as figure 1 Among them, a gantry lifting device with vertical and horizontal walking functions, including a main steel beam 7, a lifting mechanism 4, and a first auxiliary leg 1, a first main leg 2, a second Two main outriggers 10 and a second auxiliary outrigger 11;

[0033] The wheel box running direction of the first main leg 2 and the second main leg 10 is perpendicular to the wheel box running direction of the first auxiliary leg 1 and the second auxiliary leg 11, so as to realize the function of walking laterally;

[0034] The height of the wheel box of the first main leg 2 and the second main leg 10 is different from the height of the wheel box of the first auxiliary leg 1 or the second auxiliary leg 11 . The difference in height is beneficial to the passage through the hole and the laying of the main outrigger running track 9 in the later stage. In this example, the first auxiliary outrigger 1 is higher than the second auxiliary outrigger 11, and the heigh...

Abstract

The invention discloses a gantry crane device with lengthways and transverse traveling functions. The gantry crane device comprises a main steel girder and a hoisting mechanism, wherein a first auxiliary supporting leg, a first main supporting leg, a second main supporting leg and a second auxiliary supporting leg are arranged on the main steel girder in turn; the roller box traveling direction of the first main supporting leg and the second main supporting leg is vertical to that of the first auxiliary supporting leg and the second auxiliary supporting leg; and the roller box height of the first main supporting leg and the second main supporting leg is different from that of the first auxiliary supporting leg or the second auxiliary supporting leg. The gantry crane device has the advantages of high hoisting capacity, novel concept, and simple structure and is convenient to operate, is safe and reliable and is not affected by a rainy season and a flood season. In the water conservancyproject flood discharge gate hoisting construction technology, compared with the normal large crane, the gantry crane device has great advantages in economy and technology, and can simplify construction procedures to adapt to various hoisting working conditions, speed up a construction progress and highly reduce a safety hazard.

Description

technical field [0001] The invention relates to a gantry lifting device and a hoisting method, in particular to a gantry lifting device and a hoisting method with vertical and horizontal walking functions, which are suitable for the top of the gate pier of a flood discharge dam section of a large and medium-sized water conservancy project. Background technique [0002] The flood discharge structures of large and medium-sized water conservancy projects are generally equipped with porous flood discharge gates, the height of the gate pier is 20m-40m, the thickness is between 3m-4m, and the distance between the two gate piers is 16m-22m. Prefabricated concrete road beams, track girders, oil pipe trenches and tension line trench beams are erected on the top of the gate piers, and oblique arm-type arc-shaped working doors and cylinder-type hydraulic hoists are installed between the gate piers. The weight of the hoisting components is between 15 and 150 tons. According to the conve...
