Description

Technical Field

[0001] The present invention belongs to the field of construction equipment, and in particular relates to an assembling platform and a translation and jacking construction method. Background Art

[0002] When a steel box girder is pushed across an existing highway or interchange ramp by means of jacking, a platform is usually built on the side of the highway, and the steel box girder sections are connected on the platform, and then the construction across the highway or interchange ramp is realized by jacking, that is, the steel box girder of a certain span is spliced ​​before jacking, so that the steel box girder is not further spliced ​​during the jacking process. However, in the actual construction process, for example, when constructing in mountainous areas, under the influence of the geographical environment and other factors such as the mountain, it is impossible to complete the splicing of the entire span of the steel box girder in one go when splicing the steel box girder. Therefore, it is necessary to complete the splicing of a part of the steel box girder span on the platform, and then directly push one end along the predetermined trajectory, and then connect the steel box girder at one end, and repeat the operation in this manner.

[0003] However, there are certain problems in the above process. When carrying out jacking construction across existing highways or related roads, the relevant roads need to be closed, affecting traffic. Secondly, the use of multiple on-site jacking and on-site assembly of extended steel box girders in a cyclic operation mode is time-consuming and inefficient. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] See also Figure 1-9 , the present invention provides a technical solution for an assembly platform:

[0033] An assembly platform includes an assembly bracket 1, a horizontal pushing device 2, and a rotating pushing device 3. Figure 1 The assembly bracket 1 is formed by splicing steel pipes and steel plates. The assembly bracket 1 is reasonably built in a limited space according to the size of the steel box beam. Under the condition of ensuring safety and operating space, two sections of steel box beams with a certain curvature are arranged side by side. In this embodiment, for a clearer description, as shown in FIG. Figure 1 As shown, the steel box girder is divided into a first segment box girder 04 and a second segment box girder 05. The rotating jacking device 3 and the transverse jacking device 2 are both arranged between the steel box girder and the platform above the assembly bracket 1. The transverse jacking device 2 is used to push the steel box girder to move in a straight direction, and the rotating jacking device 3 is used to push the steel box girder to rotate about a predetermined axis.

[0034] The lateral jacking device 2 includes a base 6, a lifting hydraulic cylinder 7, a pushing hydraulic cylinder 8, a correcting hydraulic cylinder 9, and a slide 10. The slide 10 is slidably set on the base 6. The pushing hydraulic cylinder 8 pushes the slide 10 to slide along the base 6. The lifting hydraulic cylinder 7 is set on the slide 10. The lifting hydraulic cylinder 7 is used to lift the steel box girder in the vertical direction. The correcting hydraulic cylinder 9 is set on the slide 10. The axis of the correcting hydraulic cylinder 9 is perpendicular to the sliding direction of the slide 10. The correcting hydraulic cylinder 9 is used to adjust the position of the lifting hydraulic cylinder 7.

[0035] The difference between the rotary pushing device 3 and the horizontal pushing device 2 is that the base 6 is arc-shaped as a whole, the sliding trajectory of the slide 10 along the base 6 is an arc, a rotating seat 11 is provided in the base 6, the lifting hydraulic cylinder 7 is provided on the rotating seat 11, an adjusting seat is provided between the pushing hydraulic cylinder 8 and the base 6, the pushing hydraulic cylinder 8 is provided on the adjusting seat, the adjusting seat is slidingly provided on the base 6, the sliding direction of the adjusting seat is along the radial direction of the base 6, the correcting hydraulic cylinder 9 is provided on the base 6, the correcting hydraulic cylinder 9 is used to drive the adjusting seat to slide, and the output end of the pushing hydraulic cylinder 8 is connected to the slide 10 through a ball hinge.

[0036] The segmental steel beam can be driven to rotate by two rotating jacking devices 3. The positions of the two rotating jacking devices 3 are set so that when the axis of the lifting hydraulic cylinder 7 of one rotating jacking device 3 is located at the rotation center of the sliding arc trajectory of the slide 10 of the other rotating jacking device 3, the segmental box beam can be rotated after the two rotating jacking devices 3 lift the segmental box beam.

[0037] When the rotating jacking device 3 is working, the lifting hydraulic cylinder 7 lifts the steel box girder, and the pushing hydraulic cylinder 8 pushes the slide 10 to slide along the base 6, thereby driving the steel box girder to rotate. At the same time, the lifting hydraulic cylinder 7 rotates around the rotating seat 11. Since the output end of the jacking hydraulic cylinder 8 and the slide 10 are connected by a ball hinge, as the angle changes during jacking, the adjustment seat is driven by the correction hydraulic cylinder 9 to make the jacking hydraulic cylinder 8 push the slide 10 to move more stably.

[0038] In this embodiment, ten rotating jacking devices 3 are provided, five of which are provided at one end of the two steel box girders, and the other five are provided at the other end of the steel box girders. A plurality of transverse jacking devices 2 are provided, which are not shown in the figure. When the steel box girder rotates, the axis of the lifting hydraulic cylinder 7 of one of the rotating jacking devices 3 at one end coincides with the axis of the arc formed by the base 6 of the five rotating jacking devices 3 at the other end.

[0039] The present invention provides a construction method for a longitudinal and transverse combined translation jacking beam, comprising the following steps:

[0040] S1: According to the installation requirements of the steel box girder segments, design the layout of the temporary assembly platform in a limited space, and install the required number of lateral jacking devices 2 and rotating jacking devices 3 that can be connected to each other.

[0041] S2: Complete the splicing of the first segment box girder 04 and the second segment box girder 05 on the supporting platform.

[0042] S3: The first section box girder 04 is pushed to move under the action of the lateral pushing device 2 .

[0043] S4: Continue to push the first segment box girder 04 to move under the action of the horizontal pushing device 2, and at the same time, under the action of the rotating pushing device 3, make the second segment box girder 05 rotate around one end first, and then rotate around the other end, so that the second segment box girder 05 falls to the position when the first segment box girder 04 has not moved.

[0044] S5: Connect the first segment box girder 04 and the second segment box girder 05 together.

[0045] S6: Push the first section box girder 04 and the second section box girder 05 as a whole to move simultaneously until they reach the designated position.
