Description

Technical Field

[0001] The utility model belongs to the technical field of box girder body welding, in particular to a box girder body welding auxiliary device. Background Art

[0002] In the process of welding the box girder body, most of the time, the steel box girder is tied up with a lifting rope, and then tilted and flipped. However, the steel box girder is large in size and weight, and it is difficult to tie the steel box girder with the lifting rope. It is difficult to pass through the bottom of the steel box girder and wrap it tightly around the surface of the steel box girder, which can easily cause the steel box girder to fall when flipped, resulting in accidents and endangering the lives of workers.

[0003] Although the existing box girder welding auxiliary equipment can meet the basic needs of solid and auxiliary support for the box girder body, when it needs to be flipped and adjusted, the two sides of the box girder are often lifted up by the support structure so that the user can conveniently bundle the box girder and flip it. However, due to the heavy weight of the box girder body, the auxiliary equipment needs to be equipped with an auxiliary support structure with a stronger lifting function, which will increase the user's use cost and cannot fully meet people's use needs. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides a box girder welding auxiliary equipment, which not only meets the basic needs of flexibly fixing the box girder body and thus assisting in welding, but also enables the user to conveniently pass the rope through the bottom of the box girder body without lifting the box girder body, thereby conveniently bundling the box girder body and then flipping it over.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a box girder welding auxiliary equipment, including a base, support legs are respectively provided at the bottom corners of the base, and fixing modules for fixing the box girder body are respectively provided at the front and rear ends of the top of the base, and a placing table located between the two fixing modules is also provided on the top of the base, and rope threading holes are respectively provided at the front and rear ends of the placing table along the left and right directions, and the top of the rope threading hole also passes through the top of the placing table, and a rope threading auxiliary module corresponding to the two rope threading holes is also provided on the top of the base; the rope threading auxiliary includes an L-shaped mounting frame arranged at the side end of the base along the left and right directions and located on the outside of the corresponding rope threading hole, and a telescopic push rod is horizontally provided on the vertical part of the mounting frame, and a U-shaped rope body fixing unit adapted to the rope threading hole is provided at the end of the output shaft of the telescopic push rod.

[0006] As a further improvement of the present invention, support pads are respectively provided at the bottom of the four supporting legs, and anti-slip pads are respectively provided at the bottom of the four supporting pads.

[0007] As a further improvement of the present invention, the rope fixing unit includes a U-shaped rope release rack arranged at the end of the output shaft of the telescopic push rod, and the side end of the rope release rack is provided with a compression bolt for fixing the rope body, and the gap between the side end of the rope release rack and the side end of the rope threading hole is adapted to the rope body.

[0008] As a further improvement of the present invention, the compression bolt is a hand-tightened bolt.

[0009] As a further improvement of the present invention, a fixed pressure plate is further provided at the inner end of the compression bolt.

[0010] As a further improvement of the present invention, the fixing module includes a vertical plate arranged on the top of the base and located on the outside of the placing table, the inner end of the vertical plate is provided with a mounting groove along the left and right directions, a bidirectional screw is provided in the mounting groove for rotating along the left and right directions, and a driving motor for driving the bidirectional screw to rotate is provided at the side end of the mounting groove, and mounting blocks slidably connected to the mounting groove are respectively screwed at both ends of the bidirectional screw, and fixing splints for fixing the box girder body are respectively provided on the two mounting blocks.

[0011] As a further improvement of the present invention, a protective pad is further provided on the inner side wall of the fixed splint.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] Firstly, the technical solution of the present application is to place the box girder body on a placement table and fix the front and rear side ends of the box girder through a fixing module. The presence of the rope holes allows the user to directly pass the rope through the bottom of the front and rear sides of the box girder body without lifting the box girder body, to bundle the box girder body, and thus flip and adjust the box girder body. Therefore, it can more conveniently meet people's usage needs, so that the auxiliary equipment does not need to add an auxiliary support structure with a strong jacking function, which can reduce the user's cost.

[0014] Secondly, the user can fix the free end of the rope through the rope fixing unit, and then use the telescopic push rod to quickly pass the free end of the rope through the rope hole. After that, the free end of the rope only needs to be separated from the rope fixing unit and the rope fixing unit is reset, and the side end of the box girder can be conveniently tied through the rope.

[0015] Third, it is only necessary to place the box beam body on the placement table and make the side ends of the box beam body between the fixed splints on both sides, and then the bidirectional screw can be rotated by driving the motor to make the fixed splints contact the side ends of the box beam body, thereby clamping the box beam body.

[0016] Fourthly, the protective pad can prevent the fixed pressure plate from directly squeezing the box girder body and causing pressure loss. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] To better understand the present invention, the following examples further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be practiced without one or more of these details.

[0024] like Figure 1 、 2As shown in Figure 4, a box girder welding auxiliary equipment includes a base 101, support legs 102 are respectively provided at the bottom corners of the base 101, and fixing modules for fixing the box girder body are respectively provided at the front and rear ends of the top of the base 101, and a placement table 103 located between the two fixing modules is also provided at the top of the base 101, and rope threading holes 104 are respectively provided at the front and rear ends of the placement table 103 along the left and right directions. The top of the rope threading hole 104 also passes through the top of the placement table 103, and the top of the base 101 is also provided with rope threading auxiliary modules corresponding to the two rope threading holes 104 respectively; the rope threading auxiliary includes an L-shaped mounting frame 201 arranged at the side end of the base 101 along the left and right directions and located on the outside of the corresponding rope threading hole 104, and a telescopic push rod 202 is horizontally provided on the vertical part of the mounting frame 201, and a U-shaped rope body fixing unit adapted to the rope threading hole 104 is provided at the end of the output shaft of the telescopic push rod 202.

[0025] like Figure 2 As shown, the bottoms of the four support legs 102 are each provided with a support pad 105, and the bottoms of the four support pads 105 are each provided with an anti-slip pad 106. The support pads 105 increase the support area of ​​the device, thereby enhancing the stability of the device and reducing pressure loss on the ground; the anti-slip pads 106 increase the friction between the bottom of the device and the ground, thereby preventing the device from easily shifting.

[0026] like Figure 1 、 4 As shown, the rope securing unit includes a U-shaped rope-releasing bracket 203 mounted on the output shaft end of the telescopic push rod 202. A clamping bolt 204 is installed on the side of the rope-releasing bracket 203 to secure the rope. The gap between the side of the rope-releasing bracket 203 and the side of the rope-threading hole 104 is adapted to the rope. The clamping bolt 204 is a hand-tightened bolt. The user can conveniently adjust the clamping bolt 204 by hand, thereby conveniently securing or releasing the connection between the rope and the rope-releasing bracket 203.

[0027] As shown in the figure, the fixing module includes a vertical plate 301 arranged on the top of the base 101 and located on the outside of the placement table 103. The inner end of the vertical plate 301 is provided with a mounting groove 302 along the left and right directions. A bidirectional screw 303 is provided in the mounting groove 302 to rotate along the left and right directions. The side end of the mounting groove 302 is provided with a driving motor 304 for rotating the bidirectional screw 303. The two ends of the bidirectional screw 303 are respectively screwed with mounting blocks 305 that are slidably connected to the mounting groove 302. The two mounting blocks 305 are respectively provided with fixing splints 306 for fixing the box girder body.

[0028] The user can place the box beam body on the placement table 103, and make the front and rear side ends of the box beam body be located between the fixed clamps 306 on both sides, and then start the drive motor 304 to make the bidirectional screw 303 rotate and make the fixed clamps 306 on both sides simultaneously press against the side ends of the box beam body, thereby clamping the box beam body, and then the box beam body can be welded.

[0029] After a period of time, when the box girder body needs to be flipped and adjusted, the free ends of the rope bodies can be placed in the corresponding rope-releasing frames 203 respectively, and the compression bolts 204 can be turned and adjusted so that the two sides of the free ends of the rope bodies are respectively conflicted by the compression bolts 204 and the inner ends of the rope-releasing frames 203. Then, the output shaft of the telescopic push rod 202 can be extended to a certain length, so that the rope-releasing frame 203 and the free ends of the rope bodies can quickly pass through the rope-releasing frames 204 and move to the other side of the box girder body. After that, the compression bolts 204 can be loosened to release the fixation of the free ends of the rope bodies. After that, the free ends of the rope bodies can be taken out from the rope-releasing frames 203, and the output shaft of the telescopic push rod 202 can be shortened to a certain length so that the rope-releasing frames 203 are reset. After that, the side ends of the box girder body can be conveniently tied by the rope bodies, and then the box girder body can be flipped and adjusted, and then the box body can be removed and the box girder body can be welded.

[0030] According to another embodiment of the present invention, Figure 4 As shown, a fixing plate 205 is further provided at the inner end of the compression bolt 204. By fixing the plate 205, the user can simply place the free end of the rope into the rope rack 203 to fix the free end of the rope in the rack without having to deliberately align the free end of the rope with the inner end of the compression bolt 204.

[0031] According to another embodiment of the present invention, Figure 3 As shown, a protective pad 307 is also provided on the inner side wall of the fixed splint 306. The protective pad 307 can ensure the flexible fixation of the box girder body while preventing the fixed pressure plate 205 from directly and rigidly contacting the side end of the box girder body, thereby avoiding squeezing the box girder body and causing pressure loss.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
