[0009] Advantages of the present invention:
[0010] 1. By setting the chute and the fixing piece, when it is necessary to temporarily align and fix the steel box girder, the butt joint position of the steel box girder can be controlled to be embedded inside the fixing piece, and then the control information is transmitted to the controller through the control switch. Then the controller controls the operation of the servo electric cylinder, so that the moving piece can be forced to displace in a guiding manner, and the chute controls the guiding sliding of the moving piece, so that the two moving pieces can move and adjust the alignment accuracy at will, so that the two steel box girders can be at the same height, improving the alignment effect, avoiding slight deviations in alignment and fixing, and improving the construction efficiency;
[0011] 2. By setting the pushing piece, after the two steel box girders are aligned and butted, a large frictional force will be generated at their contact position. During the process of trimming and adjusting the moving piece, the pushing piece can utilize its own elasticity, so that the outer end of the pushing piece can contact multiple force-receiving blocks, and then be pushed by multiple force-receiving blocks. After the pushing piece is pushed, it can strike the moving piece, and at the same time, the vibration effect is released through the rectangular inner cavity, so that when the moving piece drives the steel box girder to move and align, vibration alignment can be generated, reducing the frictional force and resistance, and improving the alignment efficiency;
[0012] 3. By setting the adjusting piece and the pushing block, the pushing block can be connected to the fixing piece through the connecting head, so that when the fixing piece moves and adjusts the height, it can drive the pushing block to move and adjust the height together. At the same time, the adjusting piece can be displaced in a guiding manner inside the guide groove. After adjusting the height, the spring can push the limiting piece to be clamped with the clamping block, thereby fixing the adjusting piece and the pushing block, so that the fixing block can be at an appropriate height to support at the bottom of the fixing piece, improving the fixing effect and the anti-impact strength, so that when the fixing piece aligns and positions the steel box girder and encounters collision and impact, the fixing piece will not be deformed and damaged, improving the bearing strength and the service life.

The fixing member 203 is of a U-shaped structure and made of metal material for enabling the edge position of the steel box girder to be inserted into the inside of the fixing member 203, and then being controlled for alignment. The upper and lower sides of the outer end inside each fixing member 203 are of an inclined structure for enabling the edge position of the steel box girder to be inserted; a top plate 3, the top plate 3 is of a U-shaped plate structure, located at the top of the main body 1. On both sides of the top plate 3, there is respectively connected to a side rod 301 through a rectangular block. There are two side rods 301 in total. On both sides of the two side rods 301, there are respectively installed two adjusting members 304. The adjusting member 304 is of an I-shaped structure and can drive the pushing block 307 to slide freely, enabling the pushing block 307 to support at any height.

[0031] See Figure 6, each moving member 2 is provided with a rectangular inner cavity inside, which can amplify the vibration effect when being struck. Each inner part of the chute 201 is provided with uniformly arranged force-bearing blocks 202. The force-bearing blocks 202 are arc-shaped structures used to make sliding contact with the pushing member 103, so that the pushing member 103 can continuously strike the moving member 2. The pushing member 103 is embedded between the force-bearing blocks 202. Each bottom of the fixing member 203 is provided with a connecting groove 204. The connecting groove 204 is a T-shaped structure used to embed the connecting head 308.

Each outer end of the moving member 2 is provided with an auxiliary plate 205. The auxiliary plate 205 is fixed at the top of the fixing member 203 and can be above the fixing member 203 to improve the strength. The auxiliary plate 205 is an inverted U-shaped plate structure. Triangular grooves are respectively arranged on both sides of the auxiliary plate 205. Two pulling grooves 206 are arranged inside the top of each auxiliary plate 205. The pulling grooves 206 are L-shaped structures used to enable the pulling plate 207 to displace inside them. Above the inner end of each pulling groove 206, there is a rectangular plate. A round hole is arranged inside each rectangular plate for inserting a guide shaft. A pulling plate 207 is inserted into each pulling groove 206. The pulling plate 207 is an L-shaped structure. A guide shaft is arranged inside each pulling plate 207. The guide shaft is a T-shaped shaft structure. A spring is sleeved outside each guide shaft and can continuously extend, thereby driving the pulling plate 207 and the clamping plate 208 to displace. The guide shaft is inserted into the round hole of the rectangular plate. A clamping plate 208 is arranged at the outer end of every two pulling plates 207. Uniformly arranged wedge-shaped blocks are arranged on the inner side of each clamping plate 208 for clamping and fixing with the outer end of the servo electric cylinder 106.
[0032] See Figure 7 and Figure 8, the side rod 301 is an L-shaped plate structure. The top end of the side rod 301 is fixedly connected to the top block 104 by bolts, which can improve the fixing effect. A guide groove 302 is provided on each side of each side rod 301. The guide groove 302 is a T-shaped structure. An adjusting member 304 is embedded inside the guide groove 302, so that the adjusting member 304 can drive the pushing block 307 to slide in a guiding manner, and then adaptively adjust the position; two rows of evenly arranged clamping blocks 303 are provided on each side of each side rod 301. The clamping block 303 is a wedge-shaped structure and is used for clamping and fixing with the limiting member 306. A connecting head 308 is provided inside the top end of each pushing block 307.

The connecting head 308 is inserted into the inside of the connecting groove 204 to connect the pushing block 307 with the fixing member 203; an inner groove 305 is provided inside each adjusting member 304. The inner groove 305 is a rectangular structure. A round rod is provided inside each inner groove 305. A spring is sleeved on the outside of each round rod and is used for continuously pushing the limiting member 306 to displace, so that the limiting member 306 can be clamped and fixed with the clamping blocks 303 at different positions. A limiting member 306 is slidably sleeved on the outside of each round rod. The limiting member 306 is an F-shaped structure. The inner side of the limiting member 306 is a wedge-shaped structure. The limiting member 306 is clamped with the clamping block 303.
[0033] The usage process and working principle of the present invention: After the two steel box girders are assembled, the control main body 1 is inserted into the gap between the two steel box girders, so that the edge position of the steel box girder can be inserted into the fixing member 203. Then, the control switch 108 is used manually to transmit the control information to the controller 105, and then the controller 105 controls the operation of the servo electric cylinder 106, so that the servo electric cylinder 106 can pull the auxiliary plate 205, the moving member 2 and the fixing member 203 to move together, so that the two fixing members 203 can drive the two steel box girders to perform precise alignment at the same time, improving the precision. While the moving member 2 is displaced, the force receiving block 202 can pass through the pushing member 103. After the pushing member 103 is pushed and displaced, it can be elastically pushed back to its original position, and then strike the moving member 2, thereby generating a vibration force. So that when the device is aligning, a vibration force can be generated, and then the vibration force is transmitted to the steel box girder, so that when the steel box girder is in local contact, there will be no large resistance and friction force, improving the alignment efficiency. After alignment, the wedge-shaped block of the clamping plate 208 can be clamped and fixed to the outside of the servo electric cylinder 106, thereby realizing secondary insurance fixation. While the fixing member 203 is moving, the pushing block 307 can be driven to rise together through the connecting head 308, so that the pushing block 307 can always be in contact with the bottom of the fixing member 203. At the same time, the limiting member 306 is clamped and fixed with the clamping blocks 303 at different positions. When the fixing member 203 is temporarily aligned and fixed at a fixed position, the strength of the fixing member 203 can be improved, so that when the steel box girder encounters collision and impact, the device will not be damaged and the fixing member 203 will not be deformed.
