[0006] The screw jack is arranged between the steel member and the steel plate B.
[0007] Furthermore, the number of the transversely long and flat holes A and the number of the transversely long and flat holes B are at least three.

BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0012] The embodiments of the present invention are now described with reference to the accompanying drawings. It will be understood by those skilled in the art that the following embodiments are only used to illustrate the present invention and should not be considered as limiting the scope of the present invention. If no specific technology, connection relationship or condition is indicated in the embodiments, the technology, connection relationship, condition described in the literature in the field or the product specification is used. If the manufacturer of the materials, instruments or equipment used is not indicated, they are all conventional products that can be purchased.
[0013] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention will be understood according to specific circumstances.
[0014] like Figure 1 As shown, the utility model provides a steel member elevation adjustment device, comprising a steel plate A1, a steel plate B2, a screw jack 3 and a pin 4;
[0015] The steel plate A1 is fixed on the steel member 5, and a transverse long flat hole A11 and a longitudinal long flat hole A12 are opened on the steel plate A1; the steel plate B2 is an L-shaped structure, and its short end is vertically arranged, and a transverse long flat hole B21 and a longitudinal long flat hole B22 corresponding to the transverse long flat hole A11 and the longitudinal long flat hole A12 are opened on it; the pin 4 passes through the overlapping transverse long flat hole A11 and the transverse long flat hole B21 in sequence to fix the steel plate B2 on the steel plate A1; because the steel member 5 is still in an adjustable state before being fixed, the connection between the steel plate A and the steel member 5 whose elevation needs to be adjusted is spot-welded, so that the steel plate A can be removed after the adjustment is completed;
[0016] The screw jack 3 is provided between the steel member 5 and the steel plate B2.
[0017] According to the further optimization scheme, the number of the transverse long flat holes A11 and the transverse long flat holes B21 is at least 3, so that the utility model can adapt to the flexible adjustment of various elevations; the length of the transverse long flat holes A11 and the transverse long flat holes B21 is 60mm, the width is 10mm, and the distance between two adjacent transverse long flat holes A11 and two adjacent transverse long flat holes B21 is 30mm; of course, the above three dimensions can be adjusted according to the weight of the adjusting component when the tooling is manufactured. If the weight of the adjusting component is too large, the width of the hole can be enlarged to allow larger pins to be inserted when the tooling is working, to ensure that the pins are not deformed after being subjected to force.
[0018] Further optimization plan, the longitudinal long flat hole A12 of steel plate A1 is 2mm wider than the transverse long flat hole A11, the longitudinal long flat hole B22 of steel plate B2 is 2mm wider than the transverse long flat hole B21, and the longitudinal long flat hole A12 is opened along the midpoint of multiple transverse long flat holes A11, and the longitudinal long flat hole B22 is opened along the midpoint of multiple transverse long flat holes B21; the long flat holes opened in steel plates A and steel plates B are consistent in size and module to ensure that the pins can normally penetrate the two connecting plates during operation to form a force transmission system.
[0019] The utility model uses a spiral jack to accurately adjust the elevation of the steel component to ensure the flatness of the butt joint position of the steel component. The specifications of the spiral jack are generally 5t, 10t, 15t and 20t to meet the on-site requirements. Before the welding of the steel component, a layout drawing for installing the adjustment device is set on the layout drawing of the steel component, and the top plate, the bottom plate and the web of the steel component are laid out according to the layout drawing. After the laying out is completed, the steel plate A and the steel plate B are installed. After the installation of the steel plate A and the steel plate B is completed, the spiral jack is continued to be installed, and the handle is used for lifting to ensure that the top, bottom and web between the beam sections are in the same plane position. The precise adjustment of the elevation of the bridge component is achieved through the lifting of the spiral jack.
[0020] When in use, first spot weld steel plate A on the steel member that needs to be adjusted, place steel plate B and the jack on another fixed steel member or other force-applicable position, adjust the vertical displacement of the jack so that a row of long flat holes at one end of steel plate B is aligned with a row of long flat holes at one end of steel plate A; then insert two pins from the longitudinal long flat holes of steel plate A and slide them downward to the aligned position of the long flat holes of steel plates A and B, knock the pins horizontally into the overlapping transverse long flat holes (one on each side) to form a force transmission system; lift the jack to complete the elevation adjustment of the steel member; after the elevation adjustment is completed, fix the steel member, then knock out the pins, take the pins out of the longitudinal long flat holes of steel plate A, then remove steel plate B and the jack, and move them to the next position that needs to be adjusted.
[0021] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
