[0002] A steel structure bridge, also known as a steel structure bridge or steel bridge, is a bridge whose main load-bearing structure is made of steel. Steel structure bridges need to be assembled on site during construction, and auxiliary tooling is required for on-site assembly of steel structure bridges. The "A bridge steel beam assembly tooling" disclosed in the publication number "CN219837382U" has solved the technical drawback that connecting sections of different lengths cannot be effectively assembled. However, in actual use, auxiliary tooling of similar structures still has many defects. For example, it can only support and assemble horizontally installed secondary beams. When the secondary beam needs to be assembled at an angle with the main beam, it cannot be supported and assembled, resulting in high limitations of the tooling when used. For this reason, we have designed an auxiliary tooling for on-site assembly of steel structure bridges to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-6 The utility model provides a technical solution: an auxiliary tooling for on-site assembly of a steel structure bridge, comprising a fixing mechanism 1 and an adjusting mechanism 2 assembled on the top of the fixing mechanism 1, the fixing mechanism 1 comprising a bottom frame 101, both sides of the bottom frame 101 are fixedly installed with double-headed hydraulic cylinders 3 and double-headed motors 6 distributed up and down, the output ends of the two groups of double-headed motors 6 are fixedly installed with driving wheels 601, the output ends of the two groups of double-headed hydraulic cylinders 3 are fixedly installed with tightening hydraulic cylinders 4, the output ends of the four groups of tightening hydraulic cylinders 4 are fixedly installed with wheel plates 401, the inner sides of the four groups of wheel plates 401 are rotatably installed with tightening wheels 402, and an assembly groove 102 is provided at the central position of the bottom frame 101;

[0023] The adjusting mechanism 2 comprises a first hydraulic cylinder 201 and a third hydraulic cylinder 206, a measuring fixed plate 202 is fixedly mounted on the output end of the first hydraulic cylinder 201, a second hydraulic cylinder 204 is rotatably mounted on the inner side of the measuring fixed plate 202, a measuring clamping plate 205 is fixedly mounted on the output end of the second hydraulic cylinder 204, an adjusting fixed plate 207 is fixedly mounted on the output end of the third hydraulic cylinder 206, a fourth hydraulic cylinder 208 is rotatably mounted on the inner side of the adjusting fixed plate 207, an adjusting clamping plate 209 is fixedly mounted on the output end of the fourth hydraulic cylinder 208, and a speed change gear box 7 is fixedly mounted on the outer side of the adjusting fixed plate 207.

[0024] Based on the above-mentioned structural setting, the auxiliary tooling for on-site assembly of the steel structure bridge is composed of a fixing mechanism 1 and an adjusting mechanism 2, wherein the fixing mechanism 1 is a fixed installation structure of the tooling, with the help of the fixing mechanism 1, the tooling can be installed and fixed on the main beam of the steel structure bridge, and the adjusting mechanism 2 is an adjusting control mechanism of the tooling, with the help of the adjusting mechanism 2, the assembly angles of the main beam and the secondary beam during the construction of the steel structure bridge can be adjusted and controlled. Specifically, during the working process, the bottom frame 101 is placed on the main beam of the steel structure bridge, and the double-headed hydraulic cylinder 3 can expand the tightening hydraulic cylinder 4 by extending, and the tightening hydraulic cylinder 4 can lower the wheel plate 401 and the tightening wheel 402 by extending, so that the bottom frame 101 can be clamped on the outside of the main beam by retracting and raising the tightening wheel 402, and the driving wheel 601 can provide rolling support between the bottom frame 101 and the main beam, and the driving wheel 601 can be driven by the double-headed motor 6 to rotate and cooperate with the tightening wheel 402 to The bottom frame 101 is moved and adjusted on the main beam. The second hydraulic cylinder 204 measures the clamping plate 205 when it is retracted, so that the front of the secondary beam lifted by the crane can be clamped and fixed. The fourth hydraulic cylinder 208 adjusts the clamping plate 209 when it is retracted, so that the back of the secondary beam lifted by the crane can be clamped and fixed. At the same time, the contraction of the first hydraulic cylinder 201 and the third hydraulic cylinder 206 can lower the clamped and fixed secondary beam, and dock it with the main beam through the assembly groove 102. The docking of the main beam and the secondary beam of the steel structure bridge by the tooling is convenient for the staff to quickly assemble and fix them, which improves the speed of the staff when assembling the steel structure bridge. The output end of the speed change gear box 7 is fixedly connected to the fourth hydraulic cylinder 208, so that the angle of the fourth hydraulic cylinder 208 and the secondary beam fixed inside it can be adjusted through the speed change gear box 7, which is convenient for the staff to adjust the angle of the secondary beam and the main beam during assembly through auxiliary work, thereby increasing the functionality of the auxiliary tooling and reducing the limitations during use.

[0025] Furthermore, mounting plates 103 are fixedly installed on both sides of the bottom frame 101, and adjusting screws 5 are threadedly installed on the mounting plates 103. A locking plate 501 is rotatably installed at the bottom of the adjusting screw 5, and anti-skid patterns 502 are arranged at the bottom of the locking plate 501. The staff can lower the locking plate 501 by rotating the adjusting screw 5. The locking plate 501 will contact with the main beam when it is lowered. The contact between the locking plate 501 and the main beam can lock the mechanism during operation, ensuring the stability of the mechanism when operating on the main beam. The anti-skid patterns 502 increase the friction at the bottom of the locking plate 501, and increase the stability of the locking plate 501 when locking the mechanism.

[0026] Furthermore, a measuring dial 203 used in conjunction with the second hydraulic cylinder 204 is fixedly installed on the outer side of the measuring fixing plate 202. The input end of the measuring dial 203 is fixedly connected to the second hydraulic cylinder 204, so that the staff can measure when adjusting the angle of the secondary beam through the speed change gear box 7, which is convenient for the staff to accurately control the angle of the secondary beam during assembly based on the data detected by the measuring dial 203 at home, thereby improving the accuracy of the auxiliary tooling during on-site assembly of the steel structure bridge.

[0027] Furthermore, a drive shaft 701 extending to the outside is rotatably installed at the lower part of the speed change gear box 7. The drive shaft 701 is connected to the input end of the speed change gear box 7, and the staff can operate the drive shaft 701 through an adapted tool, so that the staff can operate and adjust the installation angle of the secondary beam during assembly through the speed change gear box 7.

[0028] Furthermore, the outer walls of the four sets of driving wheels 601 are equidistantly provided with anti-skid grooves 602. The anti-skid grooves 602 increase the friction of the outer walls of the driving wheels 601, improve the stability of the driving wheels 601 when driving the mechanism to move, and avoid or reduce the slipping of the driving wheels 601 when the mechanism moves.

[0029] Further, the bottom of the four sets of tightening hydraulic cylinders 4 and the top of the four sets of wheel plates 401 are fixedly installed with accordion covers 403. Among them, the accordion covers 403 can close and protect the output end of the tightening hydraulic cylinder 4, avoiding the situation that the tightening hydraulic cylinder 4 pinches people when shrinking.
