The application discloses an independent closed stainless steel spray pipeline for a coal cutter drum, which comprises a main stainless steel water pipe, a branch water pipe, an internal thread joint, an O-shaped sealing ring, liquid sealing glue, a stainless steel ring and a fireproof shock-absorbing sponge sleeve pipe; the end disc water pipe and the blade water pipe are connected through numerical control pipe bending and argon arc welding, the main stainless steel water pipe is drilled at the position corresponding to the drum and is connected with the internal thread joint through argon arc welding, the internal thread joint is internally provided with the O-shaped sealing ring, the branch water pipe is screwed into the internal thread joint after being coated with the liquid sealing glue (the O-shaped sealing ring is compressed to form triple sealing), the gap between the branch water pipe and the water hole of the drum is filled with the stainless steel ring and is welded through argon arc welding, and the main stainless steel water pipe is coated with the fireproof shock-absorbing sponge sleeve pipe and is separated from the drum body. The independent closed water channel is realized, rust blockage and leakage are prevented, vibration resistance and drum cracking influence are avoided, and stable operation of the spray system is ensured.

The application discloses a self-anchoring structure for integral lifting of a steel box girder, comprising a bridge tower and a constructed steel box girder, wherein the bridge tower is provided with a ring-shaped self-anchoring support body, the bottom of the bridge tower is provided with a support bottom embedded steel plate, the ring-shaped self-anchoring support body is connected with the support bottom embedded steel plate and the constructed steel box girder, the top of the constructed steel box girder is provided with a self-anchoring truss, and the end of the self-anchoring truss towards a mounting surface is provided with lifting equipment. The application further discloses a self-anchoring method for integral lifting of a steel box girder, and the steps are as follows: 1, fixing the support bottom embedded steel plate at the bottom of the bridge tower; 2, installing the ring-shaped self-anchoring support body; 3, hoisting the prefabricated steel box girder in situ, and welding adjacent prefabricated steel box girders to make them into the constructed steel box girder; 4, installing the steel box girder inner support circular pipe and the self-anchoring truss on the constructed steel box girder; and 5, installing the steel box girder to be hoisted. The application can economically and rationally lift the steel box girder to a specified position, and can be widely applied in the field of building construction steel structure installation.

The utility model relates to a remedial connecting structure for dislocation of an anchor bolt foundation and a steel column base, which comprises a first foundation, a second foundation, a first steel column, a second steel column and a steel beam, and the center distance between the first foundation and the second foundation is larger than that between a first column base bottom plate and a second column base bottom plate; the first lower anchor bolt is connected with the first end of the steel beam through the first connecting assembly, and the first column foot bottom plate is fixed to the top face of the steel beam. The second column base bottom plate is fixed to the top face of the second end of the steel beam, and the second lower anchor bolt is connected with the second end of the steel beam and the second column base bottom plate through a second connecting assembly. Or, the second end of the steel beam is fixed to the side face of the second steel column, the second column base bottom plate is placed on the top face of the second foundation, and the second lower anchor bolt is connected with the second column base bottom plate through a third connecting assembly. The utility model can effectively solve the problem that the column foot anchor bolt and the column foot bottom plate cannot be installed due to large error caused by dislocation.

The utility model belongs to the field of medium equipment installation, and particularly relates to an adjustable set top box support structure. The technical problems that a set top box support is generally perpendicular to a wall surface and cannot be installed in a crowded narrow space, and the service life of the set top box is shortened due to the heat dissipation problem are solved. According to the technical scheme, the adjustable set top box support structure comprises a rotating assembly; the device further comprises a support assembly, a folding assembly, an installation assembly and a bunching assembly. According to the utility model, the second column block is rotated, the sleeve block is taken out, the first column block is rotated, whether the supporting base is perpendicular to the wall surface or parallel to the wall surface is determined according to the size of the space, and the quick mounting plate and the supporting base are quickly fixed through the second stud, so that the set top box can be conveniently taken out for maintenance; the problem that the space utilization rate is low due to the fact that the set top box support is not suitable for being installed in a narrow space is solved, the set top box is cooled through the fan fixedly connected to the lower end of the supporting base, and the problem that the set top box is too hot is solved.
