[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Reference Figure 3 At present, during the tunnel construction process, the steel bars 3 at the lower edge of the tunnel primary support structure need to be welded with the steel bars 3 on the tunnel short side wall. There is a phenomenon of mutual crossing between the two groups of steel bars 3, resulting in fewer parts that can be welded and the firmness of the welding is greatly reduced. It is necessary to level the two groups of steel bars 3 so that the welding ends of the two groups of steel bars 3 are close to being parallel to each other.

[0022] Therefore, refer to Figure 1 and Figure 2 The utility model provides a cross steel bar leveling device, comprising a flat plate 1, a leveling mechanism 2 and a working chamber 4, wherein the flat plate 1 is made of a steel plate.

[0023] Among them, there are two groups of leveling mechanisms 2, each group of leveling mechanisms 2 includes two groups of lever arms 20 movably connected to the flat plate 1, the lever arms 20 can be made of steel pipes or steel bars, and the two groups of lever arms 20 in each group of leveling mechanisms 2 are hinged at different positions on the surface of the flat plate 1. Therefore, the two groups of lever arms 20 can cross each other during the rotation process.

[0024] The lever arm 20 can be hinged on the plate surface of the flat plate 1 or on the side wall of the flat plate 1 in this embodiment.

[0025] In this embodiment, the force arms 20 in the two sets of leveling mechanisms 2 are hinged to the plate surface of the flat plate 1, and the rotation axes of the four sets of force arms 20 are parallel to each other.

[0026] In each set of leveling mechanisms 2, a working cavity 4 is formed between the intersection of the two sets of force arms 20 and the plate surface of the flat plate 1. With the crossing rotation of the force arms 20, the size of the working cavity 4 can change accordingly. By placing the crossed steel bars 3 in the working cavity 4, the bifurcated parts of the crossed steel bars 3 can be squeezed and gathered.

[0027] By arranging two sets of leveling mechanisms 2 on the flat plate 1, and the connecting line between the working chambers 4 in the two sets of leveling mechanisms 2 is parallel to the rotation axis of the force arm 20, the bifurcated parts on both sides of the crossed steel bars 3 can be squeezed simultaneously, so that the bifurcated parts of the crossed steel bars 3 are gathered and tend to be parallel.

[0028] In addition, in some embodiments, in each set of leveling mechanisms 2, at least one set of force arms 20 has an end close to the flat plate 1 and is provided with an arc portion 210 facing the working chamber 4. When the force arms 20 are made of steel bars, the arc portion 210 can be directly formed by bending and pressing the force arms 20. The arc portion 210 can buckle the crossed steel bars 3 on the flat plate 1 to limit the relative sliding between the crossed steel bars 3.

[0029] Reference Figure 2 In one embodiment, a group of pressing blocks 21 are welded on the lever arm 20, and the arc portion 210 is directly disposed on the lower end surface of the pressing block 21 for processing, thereby avoiding the problem that it is difficult to process the arc portion 210 when the lever arm 20 is made of a steel pipe.

[0030] In addition, the pressing block 21 can be directly welded to the side wall of the lever arm 20 .

[0031] In one embodiment, referring to Figure 2 The pressing block 21 is welded to the end of the force arm 20 , and the force arm 20 is connected to the flat plate 1 through the pressing block 21 , that is, the pressing block 21 is hinged to the flat plate 1 .

[0032] In the above embodiments, the axes of the arc portions 210 in the two sets of leveling mechanisms 2 are on the same straight line.

[0033] In this embodiment, the orthographic projection of the arc portion 210 in the normal direction of the plate surface of the flat plate 1 is located on the plate surface of the flat plate 1, that is, when the force arm 20 is squeezing the steel bar 3, the arc portion 210 will not rotate to the back side of the flat plate 1 to cause the steel bar 3 to be bent.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
