[0001] The utility model belongs to the technical field of steel structure bridge construction and relates to a steel structure U-rib plate unit rapid assembly operation platform. Background Art

[0002] Steel structures, with their advantages of light weight, high strength, and strong tensile and compressive properties, are widely used in bridge construction for large-scale transportation projects, including municipal, road, rail, and river / sea bridges. Orthotropic thin-walled steel beam structures, in particular, have become the predominant structural form for steel beam bridge decks due to their light weight, high rigidity, high ultimate bearing capacity, structural continuity, and ease of fabrication.

[0003] Orthotropic bridge decks made of steel structural panels and their fully welded U-ribs form the foundation for steel beams. The panel units require pre-positioning and assembly before welding, making the assembly process crucial for both panel unit welding and overall quality. This requires high precision in the gaps between the U-ribs. Currently, there are two primary methods for assembling U-rib panel units: manual panel placement and assembly using specialized equipment.

[0004] The current main production method for assembling U-rib panel units is manual positioning and assembly. First, the U-ribs are installed and positioned using equipment such as cranes. Then, multiple sets of L-shaped and wedge-shaped code plates welded to the panel are used to press and control the precision of the U-ribs. This assembly method is complex, inefficient, and costly. In addition, the installation and removal of the code plates can easily damage the panel base material, posing a quality risk. Summary of the Invention

[0024] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text.

[0025] like Figure 1 As shown, the utility model is a steel structure U-rib panel unit rapid assembly operation platform, including a panel placement base, and a U-rib adjustment crane mounted horizontally on the top of the panel placement base. The panel placement base and the U-rib adjustment crane are used together to assemble 15 U-rib panel units as a whole.

[0026] The panel placement base is rectangular, with a crisscross structure in the plane and an I-shaped cross section. The panel placement base is provided with base longitudinal beams 1 on both sides, and the base longitudinal beams 1 on both sides are connected by six base cross beams 2. The base is used to place the plate unit panel 14, and several panel side positioning blocks 4 are intermittently installed on the outer side of the top surface of the base longitudinal beam 1 on one side. The panel side positioning blocks 4 are the alignment structure between the plate unit panel 14 and the base. The base longitudinal beam 1 and the base cross beam 2 are both made of I-beams. A driving limit plate 3 is set at both ends of the two base longitudinal beams 1. The driving limit plate 3 is a U-rib adjustment driving limit structure. The driving limit plate 3 extends upward from the base longitudinal beam 1 to prevent the driving from leaving the base.

[0027] The U-rib adjustment crane has a door-shaped structure. There are columns 5 on both sides of the U-rib adjustment crane. The tops of the columns 5 on both sides are connected by a main crossbeam 6. The columns 5 and the main crossbeam 6 are both made of I-steel. The columns 5 and the main crossbeam 6 are perpendicular to each other. Main beam sealing plates 7 are set at both ends of the main crossbeam 6. The two columns 5 are rigidly connected to the two ends of the main crossbeam 6 by welding, and beam-column reinforcement ribs 8 are set at the connection positions of the columns 5 and the main crossbeam 6, so that the overall frame of the crane has a door-shaped stable structure.

[0028] A pulley frame is installed at the bottom of the column 5, and a pulley block H1 and a limiting wheel block H2 are installed on the pulley frame. The pulley block H1 and the limiting wheel block H2 are perpendicular to each other. The pulley block H1 contacts the top surface of the base longitudinal beam 1, and the limiting wheel block H2 contacts the side surface of the base longitudinal beam 1.

[0029] like Figure 3 As shown, the pulley frame consists of a pulley base plate 11 and pulley side plates 12. The pulley base plate 11 is connected to the bottom of the column 5. The pulley block H1 is located at the bottom of the pulley base plate 11. The pulley side plates 12 are bent structures, with the top of the pulley base plate 11 connected to the upper part of the pulley side plates 12. The limiting wheel blocks H2 are installed below the pulley side plates 12. The pulley side plates 12 are located on both sides of the column 5. The pulley blocks H1 and the limiting wheel blocks H2 are arranged perpendicularly, forming the travel and left and right limiting structure of the driving vehicle.

[0030] like Figure 2 As shown, a reinforcing plate 8 is installed between the column 5, the pulley bottom plate 11, and the pulley side plate 12 to increase the connection strength between the column 5 and the pulley frame.

[0031] The outer side of the column 5 is connected to a limit hook 9 by welding. The limit hook 9 is C-shaped, and the middle part of the limit hook 9 passes around the upper flange of the base longitudinal beam 1 from the outside, and the bottom of the limit hook 9 is located below the upper flange of the base longitudinal beam 1. When the limit hook 9 moves upward with the column 5, the limit hook 9 prevents the panel placement base from being separated from the U-rib adjustment carriage.

[0032] There is a certain gap between the limit hook 9 and the upper flange of the base longitudinal beam 1, which does not affect the movement of the crane in the non-working state, and limits the upper and lower positions of the crane in the working state and provides support force.

[0033] A pedestal 13 is slidably mounted on the bottom of the main beam 6. Specifically, the bottom of the pedestal 13 is a pad 13-1, which is located below the main beam 6. Sliding hooks 13-2 are symmetrically arranged on both sides of the pad 13-1. The upper portions of the sliding hooks 13-2 extend between the upper and lower flanges of the main beam 6. The main cross pulley H3 is mounted on the upper portions of the sliding hooks 13-2 and overlaps the top surface of the lower flange of the main beam 6.

[0034] The cushion 13 creates a uniform stress condition for the traveling crossbeam; the main transverse pulley H3 provides mobility for the cushion 13.

[0035] like Figure 4 As shown, the working process of the utility model is as follows:

[0036] Step 1: Place the board unit panel 14; the panel placement base with a mesh structure can provide multi-point support for the panel 14, reducing the impact of the deflection change of the panel 14 on the assembly gap, and the intermittent continuous panel side positioning blocks 4 arranged outside the longitudinal beam 1 of the panel placement base on one side can realize the alignment function of the panel 14 and the panel placement base, thereby completing the placement of the board unit panel 14.

[0037] Step 2: Place the U-rib 15 on the panel 14 of the plate unit; Use manual labor and a crane to place the U-rib 15 on the panel 14 and complete the unfixed positioning of the U-rib 15.

[0038] Step three: move the adjustment crane to the starting end of the U-rib 15 positioning welding, press the U-rib 15, eliminate the gap between the U-rib 15 and the panel 14, and perform positioning welding of the U-rib 15 within this range; the U-rib adjustment crane can be easily operated manually, and the screw jack 16 is manually operated to utilize the support force of the adjustment crane to achieve the compression of the U-rib 15; the crane beam is provided with a basket-type cushion seat 13, which can evenly transfer the supporting force required for the compression process to the beam, and a limiting hook 9 is provided at the bottom of the column 5 to transfer the compression support force to the panel placement base to ensure that the crane can provide the supporting force required for the compression process, and the beam-column reinforcement 8 provided at the same time can effectively ensure the stability of the crane door frame structure; the setting of the crane's walking pulley and the basket-type cushion seat 13 pulley ensures that the crane structure can provide the supporting force required for the compression of the U-rib 15 at all positions within the range of the panel 14.

[0039] Step 4: After completing the positioning welding of the starting end of the U rib 15, move the crane to the other end for a certain distance and continue to press and position weld the U rib 15. Repeat this step several times to complete the positioning assembly of the U rib 15.

[0040] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
