Description

Technical Field

[0001] This utility model belongs to the field of steel box girder jacking technology, and particularly relates to a walking jacking device for steel box girders. Background Technology

[0002] When launching steel box girders using a step-by-step method, the launching jacks typically act directly on the sidewalls of the steel box girder to achieve longitudinal and transverse bridge launching displacement, or multiple identical bidirectional jacks can be used to achieve launching displacement of heavier bridges.

[0003] Currently, most of the jacking jacks used in the jacking process are temporary installations. During on-site construction, it is necessary to construct the pushing path. During the adjustment process, the steel box girder needs to be repeatedly adjusted when making multi-directional adjustments under the existing pushing method. The coordination between them is low, making it impossible to complete the jacking operation efficiently. Utility Model Content

The first hydraulic push rod pushes the lateral sliding base away from or closer to the lifting adjustment unit. The lateral adjustment unit moves perpendicular to the sliding direction of the lateral sliding base under the push of the second hydraulic push rod and the third hydraulic push rod.

[0010] Preferably, the first sliding area and the second sliding area are respectively provided with a longitudinal guide rail and a transverse guide rail, the longitudinal guide rail and the transverse guide rail do not contact each other, and the longitudinal guide rail and the transverse guide rail are arranged perpendicularly.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model embodiment provides a walking-type jacking device for steel box girders, such as... Figures 1-3 As shown, the walking-type jacking device for steel box girders is used for jacking steel box girders and includes:

[0026] A base platform 100 is provided with a first sliding area 101 and a second sliding area 102 arranged perpendicularly to each other.

[0027] The lifting adjustment unit 200 includes a longitudinal top plate 210, a hydraulic lifting component 220 for lifting the steel box girder, and a longitudinal sliding bottom plate 230. The longitudinal top plate 210 is connected to the top of the hydraulic lifting component 220, and the longitudinal sliding bottom plate 230 is disposed at the bottom of the hydraulic lifting component 220. The longitudinal sliding bottom plate 230 slides in a first sliding area 101. A second hydraulic push rod 410 and a third hydraulic push rod 420 are provided on both sides of the first sliding area 101 and are in contact with the lifting adjustment unit 200.

[0028] A lateral adjustment unit 300 slides in a second sliding region 102. The lateral adjustment unit 300 includes a lateral sliding base 320 and a first hydraulic push rod 330. The movement direction of the first hydraulic push rod 330 is perpendicular to the movement directions of the second hydraulic push rod 410 and the third hydraulic push rod 420.

[0029] The lifting adjustment unit 200 and the lateral adjustment unit 300 are respectively connected to the steel box girder. The first hydraulic push rod 330 pushes the lateral sliding base 320 away from or closer to the lifting adjustment unit 200. The lateral adjustment unit 300 moves perpendicular to the sliding direction of the lateral sliding base 320 under the push of the second hydraulic push rod 410 and the third hydraulic push rod 420.

[0030] Here, it is assumed that the sliding direction of the lateral adjustment unit 300 is the first direction, and the direction perpendicular to the first direction is the second direction. When the steel box girder needs to slide along the first direction, the hydraulic lifting component 220, made of jacks, lowers its height, disengaging the longitudinal top plate 210 from the steel box girder. At this time, only the lateral top plate 310 on the top of the lateral sliding base 320 supports the steel box girder. When the first hydraulic push rod 330 pushes the lateral sliding base 320 away from or towards the lifting adjustment unit 200, the steel box girder can move along the first direction. When the steel box girder needs to slide along the second direction, the hydraulic lifting component 220 will actively rise, allowing the longitudinal top plate 210 to move away from the steel box girder. The top plate 210 is connected to the steel box girder, while the transverse top plate 310 is disconnected from the steel box girder. Subsequently, the second hydraulic push rod 410 and the third hydraulic push rod 420 operate simultaneously, pushing the lifting adjustment unit 200 to slide along the first sliding area 101. The steel box girder slides along the second direction along with the longitudinal top plate 210. The lifting adjustment unit 200 and the transverse adjustment unit 300 complete the adjustment in different directions alternately, so that the jacking adjustment of the steel box girder in different directions will not interfere with each other. The lifting adjustment unit 200 and the transverse adjustment unit 300 independently complete the adjustment of the steel box girder in different directions with the cooperation of each other, avoiding the need for repeated adjustments and improving the efficiency of the jacking operation.

[0031] In a preferred embodiment of this invention, the first sliding area 101 and the second sliding area 102 are respectively provided with a longitudinal guide rail 110 and a transverse guide rail 120, which do not contact each other and are arranged perpendicularly; the longitudinal sliding base plate 230 is provided at the bottom of the hydraulic lifting component 220 and slides on the longitudinal guide rail 110; the bottom of the transverse sliding base 320 is provided with a transverse sliding plate and slides on the transverse guide rail 120.

[0032] In this embodiment, the third hydraulic push rod 420 and the second hydraulic push rod 410 are identical in structure and arranged opposite each other on both sides of the hydraulic lifting component 220. The third hydraulic push rod 420 and the second hydraulic push rod 410 adopt a hydraulic jack structure. One end of the jack is fixed on the base platform 100, while the plunger part of the jack abuts against the outer wall of the hydraulic lifting component 220. Here, the front end of the plunger is provided with an arc-shaped pad that fits the side wall of the hydraulic lifting component 220. In the actual adjustment process, the third hydraulic push rod 420 and the second hydraulic push rod 410 cooperate with each other, with one side pushing out and the other side needing to retract, to enhance the stability of operation.

[0033] The first hydraulic push rod 330 moves along the transverse guide rail 120. One end of the first hydraulic push rod 330 is fixed on the base 100, and the plunger part of the first hydraulic push rod 330 is fixedly connected to the transverse sliding base 320.

[0034] In a preferred embodiment of this invention, both the transverse sliding plate and the longitudinal sliding base plate 230 are T-shaped structures, and the longitudinal guide rail 110 and the transverse guide rail 120 are adapted to the longitudinal sliding base plate 230 and the transverse sliding plate, respectively.

[0035] In this embodiment, the steel box girder generally applies sufficient positive pressure to the longitudinal top plate 210 and the transverse top plate 310. Therefore, the transverse sliding plate and the longitudinal sliding bottom plate 230 are both T-shaped structures. The pressure is distributed by the longitudinal guide rail 110 and the transverse guide rail 120, and there is no need to set a ground-facing limiting structure.
