Embodiment Construction

[0043] The following is attached Figure 1-2 The application is described in further detail.

[0044] The embodiment of the present application discloses a reciprocating pulling type continuous pulling device for super large tonnage steel box girder. refer to figure 1 , The reciprocating pull type super large tonnage steel box girder continuous traction device includes an anchor base 1, a main frame 2, a jacking mechanism 4, a pad beam 5, a deviation correction mechanism 6 and a traction mechanism 3.

[0045] refer to figure 1 The anchor base 1 includes an anchor base plate 11 and a limit strip 12. Two limit strips 12 are arranged at intervals along the length direction of the anchor base plate 11 on the anchor base plate 11. The two limit strips 12 are fixed on the anchor base plate 11 along the length direction by bolts. On both sides of the two limiting strips 12, the top wall of the anchoring bottom plate 11 has been mirror-polished and coated with lubricating oil.

Abstract

The invention relates to a reciprocating pulling type super-tonnage steel box girder continuous traction device and a using method thereof. The traction device comprises an anchoring base, a main frame, a traction mechanism and a jacking mechanism. The main frame is slidably arranged on the anchoring base, the traction mechanism is fixedly arranged on the anchoring base, the traction mechanism is used for driving the main frame to slide back and forth in the length direction of the anchoring base, and the jacking mechanism is arranged in the main frame. The using method comprises the steps: erecting the temporary piers, installing the traction device on the temporary piers, hoisting the steel box girders to the temporary piers, assembling the steel box girder sections, controlling the jacking mechanism to conduct synchronous jacking, and jacking up the steel box girder sections; controlling the traction mechanism to drive the whole steel box girder section to advance; controlling the traction device jacking mechanism to reset, so the steel box girder sections are parked to the temporary piers; controlling the traction mechanism to reset; and repeating the control process of the traction device until the steel box girder section is in place. The construction method has the effects of reducing the work amount during installation and construction of the super-tonnage steel box girder and improving the construction efficiency.

Description

technical field [0001] The present application relates to the field of installation and construction of super-large-tonnage steel box girders, in particular to a reciprocating pull-type super-large-tonnage steel box girder continuous traction device and its use method. Background technique [0002] In the process of basic transportation facilities construction, bridge construction is the key content and the lifeline of the whole transportation facilities. In the construction of roads and bridges, the construction of rivers, railways, highways and other areas is often involved, and these areas often have site restrictions, and steel box girders cannot be hoisted directly. At present, the jacking construction technology is often used for construction. [0003] The Chinese invention patent application with the application number 201611239080.1 discloses a steel box girder sliding traction system and its construction method. The steel box girder sliding traction system includes ...
