Compared with the prior art, this application can remove and fix along with the welded joint, has solved the wet seam of overpass roof beam tradition and has connect the sediment fill simple structure, have enough to meet the need and use inconvenient, workman's use will not be strong scheduling problem in welding construction operation process.
Description
Technical Field
The utility model relates to the field of wet seam welding, in particular to the field of welding slag collection during wet seam welding.
Background
At present, a flat plate type slag receiving hopper is generally adopted in the construction of wet joints of prefabricated small box girders in an overhead engineering, and a rope or a hook is used as a safety protection tool in welding construction. Because the characteristics of the viaduct beam construction structure, the height is higher during construction, the construction platform is narrow and small, the installation, the turnover and the use of the structure are inconvenient, and the structure is fixed on the steel bars in a wet welding seam welding area by ropes in a working state, the ropes are easy to break in the welding process, and high-altitude falling objects, casualties and property loss are caused.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides the device for preventing the welding slag of the wet joint welding of the viaduct girder from falling off, and the device has the characteristics of light structure, easiness in operation, convenience in movement, strong protection, remarkable improvement on the working efficiency of workers and the like. The problems that the traditional slag receiving bucket is simple in structure, inconvenient to use in circulation, not strong in use intention of workers and the like in the welding construction operation process of the wet joint of the viaduct are solved.
In order to solve the technical problem, the utility model is solved by the following technical scheme: the device for preventing welding slag from falling off during welding of wet seams of viaducts comprises a slag receiving hopper, one end of the slag receiving hopper is provided with an inclined support rod, the inclined support rod is provided with an anti-falling rod, the anti-falling rod is provided with a plurality of sliding wheels, the anti-falling rod is further connected with a tail rod, and the tail rod is provided with an adjustable hook.
Preferably, the slag receiving hopper can pass through the wet seam between the box girder top plates on two sides of the wet seam.
Preferably, the width of the slag receiving hopper is at least 20cm wider than the width of the wet joint.
Preferably, the tail rod is parallel to the slag receiving hopper.
Preferably, the sliding wheels are respectively arranged at two ends of the anti-falling rod.
The device for preventing the welding slag from falling is movable and simple and convenient to operate, and meets the requirement of preventing the welding slag from falling during high-altitude welding. The device determines the width of the slag receiving hopper according to the width of a wet joint of a bridge, the width is generally 20-30cm wider than the wet joint, the horizontal height of the slag receiving hopper and a falling prevention rod is determined according to the thickness of box girder top plates on two sides of the wet joint, a balance system is formed by utilizing an inclined strut, the falling prevention rod, a tail rod and an adjustable hook, the balance system is placed at the position of the wet joint needing to be welded and serves as a device for preventing the falling of the spot welding slag, and the device can move and be fixed along with the device after the welding is finished and can be used along with the welding until the slag receiving hopper is full.
Compared with the prior art, this application can remove and fix along with the welded joint, has solved the wet seam of overpass roof beam tradition and has connect the sediment fill simple structure, have enough to meet the need and use inconvenient, workman's use will not be strong scheduling problem in welding construction operation process.

Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.
Example 1: as shown in fig. 1, the device for preventing welding slag from falling off during welding of wet seams of viaduct bridges comprises a slag receiving bucket 1, wherein an inclined strut 2 is arranged at one end of the slag receiving bucket 1, an anti-falling rod 3 is arranged on the inclined strut 2, a plurality of sliding wheels 5 are arranged on the anti-falling rod 3, the anti-falling rod 3 is further connected with a tail rod 4, and an adjustable hook 6 is arranged on the tail rod 4. The slag receiving hopper 1 can pass through the space between the top plates of the box girders A at the two sides of the wet joint. The width of the slag receiving hopper 1 is at least 20cm wider than that of the wet joint. The tail rod 4 is parallel to the slag receiving hopper 1. The sliding wheels 5 are respectively arranged at two ends of the anti-falling rod 3.
As shown in fig. 2 to 4, the placing process of the present application is: the assembled slag receiving hopper 1 part of the device is firstly vertically placed below the top plate of the small box girder A along the gap between the wet joints. The device is rotated to ensure that the anti-falling rod 3 is perpendicular to the wet joint and is firmly fixed. The tail rod 4 is pressed down to ensure that the part of the slag receiving hopper 1 is closely attached to the bottom of the wet joint of the box girder A. The adjustable hook 6 on the tail rod 4 is fixed on the wet joint reinforcing steel bar B to prevent the end of the lower slag receiving hopper 1 from drooping and leaking out of the gap to cause the dropping of the spot welding slag. After the welding of the part under the slag receiving hopper 1 is completed, the adjustable hook 6 is loosened, and the sliding wheel 5 is utilized to slide forwards, so that the subsequent wet joint reinforcing steel bar welding construction can be carried out.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
