The invention discloses a maintenance method for a frame roller of a roughing mill, which uses a roughing mill frame roller maintenance fixture which comprises a push-pull trolley, a roller replacing hook, a roller replacing rail mechanism, a transverse moving trolley, a lifting device and the like. The maintenance method includes: integrally demounting the frame roller before lifting, erecting arail of the roller replacing rail mechanism below a frame roller mounting position, pushing the transverse moving trolley right below the frame roller, descending the frame roller on the transverse moving trolley, pulling out the frame roller along the roller replacing rail mechanism to a position above the transverse moving trolley, and using the lifting device for lifting before rotating at a certain angle, so that the push-pull trolley can be pulled out of a roughing mill gateway for maintenance and replacement. Using the maintenance method can realize demounting and lifting of the roughing mill frame roller, enable the demounting and lifting process to be convenient and quick, increase maintenance speed and reduce labor intensity. Therefore, continuity, high efficiency, stability and smoothness of hot rolling production can be guaranteed, high efficiency, orderliness and high quality of maintenance can be guaranteed, and online maintenance time for the frame roller is shortened.

The invention relates to a novel car coupler tail frame conveyor for a wagon. The novel car coupler tail frame conveyor for the wagon comprises a motor reducing gear 1, a driving chain wheel 2, a driven chain wheel 3, a chain 4, a supporting chain row 5 and a frame 6, and is characterized in that the car coupler tail frame conveyor drives the driving chain wheel 2 to run through the motor reducing gear 1, so as to enable a car coupler tail frame to convey with the running of the supporting chain row 5. The novel car coupler tail frame conveyor provided by the invention has the advantages as follows: the conveying of the car coupler tail frame is enabled to achieve automatic flow line production.

The invention relates to a novel wagon hook body conveyor which comprises a motor reducer 1, a drive chain wheel 2, a driven chain wheel 3, a chain 4, a supporting chain row 5 and a machine frame 6. The novel wagon hook body conveyor is characterized in that the wagon hook body conveyor drives the drive chain wheel 2 to operate through the motor speed reducer 1, so that a wagon hook body is conveyed along with the operation of the supporting chain row 5. The novel wagon hook body conveyor mainly has the advantage of achieving automatic flow process of conveying the wagon hook body.

The invention discloses a rack roller overhauling fixture for a rough mill. The rack roller overhauling fixture comprises a trolley, a roller replacement hook, a roller replacement rail mechanism, a translational trolley, a lifting device and the like. When the fixture is used for overhauling, a rack roller is wholly disassembled and lifted; a rail of the roller replacement rail mechanism is erected below a rack roller mounting position; the translational trolley is pushed to a position right under the rack roller; the rack roller is lowered onto the translational trolley, is pulled out to a position above the translational trolley along the roller replacement rail mechanism, and then rotates a certain angle after being lifted by the lifting device; and the trolley can be pulled out of a mill house by a roller replacement trolley of the rough mill for overhauling and replacement. The rack roller of the rough mill can be disassembled and listed, and the disassembly and lifting processes are convenient and fast; and the rack roller is disassembled and conveyed to the outside for overhauling, so that overhauling speed is increased, and labor intensity is reduced. Therefore, by the fixture, the continuity, high efficiency, stability and direct motion of hot rolling production can be ensured; the high efficiency, sequence and high quality of the overhauling are ensured; and the online overhauling time of the rack roller is shortened.

The invention discloses a classroom lighting intelligent control lighting system, which comprises an intelligent system control box body, an inspection port is opened on the top of the intelligent system control box body, and a sealed door is movably installed inside the inspection port, and the inspection port A circular placement groove is provided on the front side of the inner wall, an extruding device is fixedly installed inside the circular placement groove, and a circular groove is provided on the front side of the airtight door. In this invention, by setting the intelligent system control box body, inspection port, sealed door, circular placement groove, extrusion device, extrusion spring, moving block, connecting block, push-pull handle, pushing block, circular groove, fixing mechanism, The combination of pneumatic cylinder, piston, extrusion rod, circular stopper, fixed rod, limit groove, limit block, strip groove, hinged seat and lifting groove solves the troublesome process of existing maintenance, which is not conducive to For the problem of quick maintenance, the classroom lighting intelligently controls the lighting system, which has the advantage of quick maintenance.

A sliding type direct-current energy dissipation device unit fixing device comprises a main body; the main body is fixedly connected to an energy dissipation device frame; at least one set of sliding rail beams are fixed to the upper side of the main body; and a direct-current energy dissipation device unit is arranged above the sliding rail beams in a sliding mode so as to slide to a preset position above the sliding rail beams to be installed. A rear fixing plate is arranged at one end of each sliding rail beam, and the rear fixing plates are connected to the energy dissipation device frame, matched with the direct-current energy dissipation device unit and used for playing a role in guiding and positioning when the direct-current energy dissipation device unit is installed. According to the sliding type direct-current energy dissipation device unit fixing device, the purpose of flexible installation, overhaul and replacement of the direct-current energy dissipation device unit is achieved, the device is simple in structure, convenient to assemble, detachable, easy to operate and store, safe and reliable, and various operations such as installation, overhaul and replacement of the direct-current energy dissipation device unit can be completed rapidly, safely and stably.
