[0034] The adjustable H-beam butt joint device provided in this embodiment is used for butt joint correction of H-beams at both ends during bridge construction.

[0035] like Figure 1 , Figure 2 As shown, a specific implementation of the adjustable H-beam docking device provided in this embodiment includes a first H-beam 1 and a second H-beam 2, wherein the second H-beam 2 is located on one side of the first H-beam 1, and the two extend in the same direction; the adjustable H-beam docking device includes: a correcting piece 3, a clamping assembly, and a jacking device 4. The first end of the correcting piece 3 is provided with a clamping assembly for clamping the first H-beam 1, and the clamping assembly can clamp the upper flange portion of the first H-beam 1, and the second end of the correcting piece 3 abuts against the upper end surface of the second H-beam 2; one end of the jacking device 4 is fixedly arranged, and the driving end of the jacking device 4 abuts against the correcting piece 3.

[0036] Specifically, Figure 3 As shown, during vertical adjustment: when the jacking device 4 is placed on the upper end surface of the second H-shaped steel beam 2, and the driving end of the jacking device 4 abuts against the lower end surface of the correcting member 3, the correcting member 3 is driven to move by the jacking device 4, thereby adjusting the drop between the first H-shaped steel beam 1 and the second H-shaped steel beam 2 in the vertical direction, so that the upper end surfaces of the first H-shaped steel beam 1 and the second H-shaped steel beam 2 are flush;

[0037] At the same time, if Figure 4 , Figure 5 As shown, during horizontal adjustment: when the jacking device 4 is placed flat on the second H-beam 2, one end of the jacking device 4 is fixed to the second H-beam 2, and the driving end of the jacking device 4 abuts against the correcting member 3; when the jacking device 4 is located on the side away from the second H-beam 2, the correcting member 3 is driven to move so as to make the first H-beam 1 away from the second H-beam 2; when the jacking device 4 is located in the correcting member 3, the first H-beam 1 is driven to approach the second H-beam 2 by driving the correcting member 3; in order to increase the structural strength of the correcting member 3, a first reinforcing plate 5 and a second reinforcing plate 6 are provided. The first reinforcing plate 5 is provided on the side end surface of the first end of the correcting member 3, and the extension direction of the first reinforcing plate 5 is the same as the extension direction of the first H-beam 1, and the first reinforcing plate 5 is a rectangular plate.

The second reinforcing plate 6 extends outward in the horizontal direction. When the jacking device 4 abuts against the correcting member 3 horizontally, the driving end of the jacking device 4 abuts against the correcting member 3 and also abuts against the second reinforcing plate 6.

The third reinforcing plate 7 has a first state in which the end face of the third reinforcing plate 7 abuts against the locking member 8 to form a fixed state, and a second state in which the fixation is released and the third reinforcing plate 7 is freely rotated. When the lifting device 4 is in horizontal adjustment, the third reinforcing plate 7 is lowered and clamped to the locking member 8 for fixing, and a frame structure is formed between the third reinforcing plate 7 and the correcting member 3. At this time, when the lifting device 4 drives the correcting member 3, the third reinforcing plate 7 can strengthen the structural strength of the correcting member 3. In addition, as an alternative embodiment, the third reinforcing plate 7 may not be arranged, and the lifting device 4 can also adjust the correcting member 3 in the horizontal and vertical directions. In addition, as an alternative embodiment, the rotating end of the third reinforcing plate 7 is arranged at the end of the first end of the correcting member 3. After rotation, a frame structure is formed between the third reinforcing plate 7 and the correcting member 3.

In addition, as an alternative embodiment, the positioning member 10 may not be provided, and the third reinforcing plate 7 can also be connected to the locking member 8 to increase the structural strength of the correcting member 3. In addition, as an alternative embodiment, the positioning member 10 may also be provided as a square column.

The limit members 13 are slidingly arranged on the extension plate 12, so that they can adapt to different models of first H-shaped steel beams 1. In addition, as a replaceable embodiment, the clamping assembly can also be set to two cylinders, and the two cylinders are symmetrically arranged on both sides of the first end of the correcting member 3, and the limit members 13 are installed at the driving end of the cylinder.

[0044] like Figure 2 As shown, in this embodiment, the extension plate 12 is symmetrically provided with a slide groove 15, the fastener 14 passes through the slide groove 15 and is connected to the limiter 13, the limiter 13 is slidably arranged in the slide groove 15 through the fastener 14, and the sliding direction of the slide groove 15 is perpendicular to the extension direction of the first H-shaped steel beam 1. One side of the slide groove 15 is an opening, and the limiter 13 can be slid out of the opening for removal, which is convenient for replacing different types of limiters 13, thereby clamping the upper flange of the first H-shaped steel beam of different thicknesses. In addition, as a replaceable embodiment, a slide rail is installed on the extension plate 12, and the limiter 13 is slidably arranged on the slide rail.

[0045] like Figure 2As shown, in this embodiment, the fastener 14 is a bolt, which passes through the slide groove 15 and is threadedly connected to the upper end surface of the limiter 13. When sliding is required, the bolt can be loosened to allow the limiter 13 to slide in the slide groove 15, and when fixing is required, the bolt can be tightened to fix it.

The first H-beam 1 is placed on one side of the second H-beam 2, and the extension directions of the first H-beam 1 and the second H-beam 2 are the same. The first end of the correcting member 3 is located on the first H-beam 1, and the second end abuts against the upper end surface of the second H-beam 2. Loosen the fastener 14 at the first end of the correcting member 3, move the limiting member 13 to be clamped on the upper flange of the first H-beam 1, and screw the fastener 14 to fix the limiting member 13.

[0048] Working principle of the adjustable H-beam docking device: When the jacking device 4 drives the correcting member 3 to move vertically, the first reinforcing plate 5 can abut between the correcting member 3 and the first H-beam 1, thereby increasing the structural strength of the correcting member 3. At the same time, when the jacking device 4 adjusts the correcting member 3 horizontally, the driving end of the jacking device 4 abuts against the second reinforcing plate 6, and the second reinforcing plate can play an auxiliary role. The rotating end of the third reinforcing plate 7 is set in the middle position of the first end of the correcting member 3, and after rotation, it is clamped to the second end of the correcting member 3, thereby helping to increase the structural strength.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
