Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a deviation correction device for the butt joint construction of a combined highway-rail steel truss girder segment. Background Technique

[0002] In the field of bridge construction, especially in the construction of combined highway-rail bridges, the steel truss girder, as a common structural form, is widely used due to its high strength, light weight and good spanning ability. The traditional construction technology for the butt joint of steel truss girder segments usually relies on the combination of a tractor and a slideway beam. The tractor is installed on the surface of the slideway beam, and the steel truss girder segment is moved and butted through the tractor. Although this method realizes the precise butt joint of the steel truss girder to a certain extent, there are still some limitations;

[0003] The Chinese authorized utility model patent (publication number: CN219315522U) discloses a deviation correction device for the jacking construction of a steel truss girder. The device places the steel truss girder on the tractor in the deviation correction device, and the lower rim of the tractor is mutually restricted with the slideway beam track to ensure the lateral offset. However, the device supports the steel plate through a heightening block, and the height of the heightening block is fixed. During the butt joint construction of the steel truss girder segment, if there is a deviation in the height of the steel truss girder, it will directly affect the butt joint accuracy and the overall performance of the bridge. Although it can be tried to correct by adjusting the height of the slideway beam or the tractor, this method is complex in operation and difficult to precisely control, often resulting in low construction efficiency and increased costs. Therefore, a deviation correction device for the butt joint construction of a combined highway-rail steel truss girder segment is proposed to overcome the above defects. Content of the Utility Model

[0004] The purpose of the utility model is to provide a deviation correction device for the butt joint construction of a combined highway-rail steel truss girder segment. By limiting the bearing platform through an adjusting plate, the height of the steel truss girder on the steel plate is adjusted by a hydraulic cylinder, solving the problem that it is difficult to adjust the deviation in height during the butt joint construction of the steel truss girder segment.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model is a deviation correction device for the butt joint construction of a combined highway-rail steel truss girder segment, including a tractor body. Hydraulic cylinders are installed on both top sides of the tractor body. The output end of the hydraulic cylinder is connected with a bearing platform, and a bearing groove is opened in the bearing platform, and a steel plate is installed in the bearing groove.

[0007] A plurality of limiting mechanisms are installed on the top of the tractor body. The limiting mechanism has a support plate and an adjusting plate. A limiting groove is opened inside the support plate, a limiting plate is slidably matched in the limiting groove, an adjusting plate is installed on the top of the limiting plate, and the adjusting plate is connected with the bottom of the bearing platform.

[0008] Preferably, sliding grooves are provided on both sides of the load-bearing platform, and rectangular blocks are slidably fitted in the sliding grooves.

[0009] Preferably, rectangular grooves are provided on both sides of the steel plate, and one side of the rectangular block is fitted in the rectangular groove.

[0010] Preferably, a screw rod penetrates through the bottoms of the load-bearing platform and the steel plate, and the screw rod is threadedly fitted in the rectangular block.

[0011] Preferably, a pulling block is installed on one side of the rectangular block, and an anti-slip pad is installed on the pulling block.

[0012] Preferably, anti-slip lines are provided on the top of the steel plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. Under the combined action of the hydraulic cylinder and the adjusting plate, when there is a deviation in the docking height, the hydraulic cylinder is started at this time, so that the limiting plate slides in the limiting groove to limit the movement of the adjusting plate, and the output end of the hydraulic cylinder jacks up the load-bearing platform to drive the steel truss girder to move vertically, preventing the steel truss girder from shifting in position during docking, ensuring that the docking surface heights of each section are consistent, significantly improving the docking accuracy of the steel truss girder, thereby reducing the structural stress concentration and potential safety hazards caused by height deviation, and instantaneously responding to adjust the height of the steel truss girder according to the actual situation, ensuring the continuity and efficiency of construction, avoiding the use of additional manpower and material resources, reducing costs, and avoiding resource waste;

[0015] 2. Under the combined action of the rectangular block and the screw rod, when installing the steel plate, the steel plate is placed in the load-bearing groove. At this time, the rectangular block is inserted horizontally to initially limit the steel plate, and then the screw rod is rotated and threadedly fitted into the rectangular block to further increase the stability of the steel plate on the load-bearing platform, preventing the steel plate from shifting in position on the load-bearing platform during the movement and docking of the tractor body, thereby ensuring the construction efficiency, avoiding the inability to dock the steel truss girder sections due to the shift of the steel plate position, and avoiding the wear between the steel plate and the load-bearing platform, extending the service life of the device.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Referring to Figures 1-4 , a deviation correction device for the docking construction of a combined highway-rail steel truss girder segment, includes a tractor body 1. Hydraulic cylinders 2 are installed on both top sides of the tractor body 1. The output end of the hydraulic cylinder 2 is connected to a load-bearing platform 3. A load-bearing groove 301 is opened in the load-bearing platform 3. A steel plate 7 is installed in the load-bearing groove 301. Chutes are opened on both sides of the load-bearing platform 3. A rectangular block 8 is slidably fitted in the chute. A pulling block 9 is installed on one side of the rectangular block 8. An anti-slip pad is installed on the pulling block 9. The anti-slip pad is a rubber pad. By providing the pulling block 9, it is convenient to connect the rectangular block 8 to the rectangular groove 701. Rectangular grooves 701 are opened on both sides of the steel plate 7. One side of the rectangular block 8 is fitted in the rectangular groove 701. An anti-slip pattern 702 is opened on the top of the steel plate 7. By providing the anti-slip pattern 702, the friction force when the steel truss girder is installed on the steel plate 7 can be increased, and the stability during the use of this device is increased. A screw 10 penetrates through the bottom of the load-bearing platform 3 and the steel plate 7. The screw 10 is threadedly fitted in the rectangular block 8. By providing the screw 10, when the rectangular block 8 is connected to the rectangular groove 701, the rectangular block 8 can be fixed, and the stability of the connection between the steel plate 7 and the load-bearing platform 3 is increased. When installing the steel plate 7, place the steel plate 7 in the load-bearing groove 301. At this time, horizontally insert the rectangular block 8 into the rectangular groove 701 to perform preliminary limitation on the steel plate 7, and then rotate the screw 10 at the bottom of the load-bearing platform 3 to be threadedly fitted into the rectangular block 8 to further increase the stability of the steel plate 7 on the load-bearing platform 3, preventing the steel plate 7 from shifting in position on the load-bearing platform 3 during the movement and docking of the tractor body 1.

[0023] Multiple groups of limiting mechanisms are installed on the top of the tractor body 1. The limiting mechanism has a support plate 4 and an adjusting plate 6. A limiting groove 401 is opened inside the support plate 4. A limiting plate 5 is slidably fitted in the limiting groove 401. An adjusting plate 6 is installed on the top of the limiting plate 5. The adjusting plate 6 is connected to the bottom of the load-bearing platform 3. When the steel truss girder is docked and placed on the steel plate 7, when there is a deviation in the docking height, at this time, start the hydraulic cylinder 2, so that the limiting plate 5 slides in the limiting groove 401 to limit the movement of the adjusting plate 6. At this time, the adjusting plate 6 limits the movement of the load-bearing platform 3, so that the output end of the hydraulic cylinder 2 jacks up the load-bearing platform 3 to drive the steel truss girder to move vertically, preventing the steel truss girder from shifting in position during docking.
