The invention relates to the field of instrument maintenance, in particular to an electrical instrument maintenance platform. The height of an existing electrical instrument overhaul platform is difficult to adjust, an electrical instrument is inconvenient to overhaul and observe by a worker, and the angle of the electrical instrument is inconvenient to adjust in the overhaul process, so that the overhaul efficiency is low. An electrical instrument maintenance platform comprises a bottom frame and the like. A table is slidably connected to the bottom frame, a storage grating is fixedly connected to the top of the table, a clamping mechanism is arranged on the table, the clamping mechanism is used for limiting and clamping an electrical instrument, and a rotating mechanism is arranged on the bottom frame. The electric instrument is limited through the two first clamping plates and the two second clamping plates, the electric instrument can be more stable in the overhauling process, meanwhile, the guide groove table and the electric instrument are driven to rotate through the clamping block rotating shaft, the angle of the electric instrument can be adjusted more conveniently in the overhauling process, and then the overhauling efficiency of the electric instrument is improved.

The utility model discloses an SFP (Small Form-factor Pluggable) optical module, which comprises an external interface connector, an RS232 chip / RS485 chip, a network serial port unvarnished transmission chip, a transceiving chip, a golden finger and a singlechip, the singlechip is connected with the transceiving chip through a serial interface, the singlechip is connected with the golden finger through an IIC (Inter-Integrated Circuit) bus interface, and the serial port unvarnished transmission chip is connected with the golden finger. The golden finger is connected with a SERDES interface of the transceiving chip, the transceiving chip is connected with the network serial port unvarnished transmission chip, the network serial port unvarnished transmission chip is connected with the RS232 chip / RS485 chip, and the RS232 chip / RS485 chip is connected with an external interface connector. The SFP optical module provided by the utility model is plug-and-play, does not need tedious installation and wiring processes, greatly saves the space, and improves the convenience compared with a conventional serial server.

The utility model provides an elevator pulley convenient to overhaul, which belongs to the technical field of elevators and comprises an elevator car, a mounting rod, pulley mounting blocks and a pulley block, the mounting rod is fixedly arranged in the center of the upper surface of the elevator car, the pulley mounting blocks are mounted at the left end and the right end of the mounting rod, and the pulley block is fixedly mounted above the pulley mounting blocks; when the pulley block needs to be overhauled, the pawl is rotated to be separated from the gear, then the rotating shaft is rotated to drive the gear, the gear drives the rack to move, the two sliding blocks move in the opposite directions along the sliding grooves, and the sliding blocks drive the pulley installation blocks and the pulley block installed above the sliding blocks to move in the opposite directions. And the pulley block is separated from the sliding rail in the elevator shaft, so that the pulley block is convenient to overhaul.

The invention relates to the field of power system equipment, and discloses a high-voltage ring main unit which comprises a cabinet body and a controller, a plurality of cavities are formed in the cabinet body, a cabinet door is arranged on the front face of the cabinet body, an auxiliary maintenance mechanism is arranged on the back face of the cabinet body, and the auxiliary maintenance mechanism is used for opening a sealing door arranged on the back face of the cabinet body during maintenance. And the sealing door corresponds to the plurality of chambers. In the normal use state, the back face of the ring main unit is in a closed state, once the ring main unit needs to be overhauled, the two rotating handles are sequentially rotated downwards, the two rotating handles are converted into a vertical parallel state from a transverse opposite state, other spring bolts at the bottom lose upward lifting force and automatically fall under the action of the dead weight of the other spring bolts, and therefore the ring main unit can be overhauled. Therefore, the sealing door is opened; the rotating handle is arranged to be high, meanwhile, a plurality of rotating handles do not need to be arranged, short children lack acting points, the situation that the children touch the rotating handle at will can be avoided as much as possible, and the function of reducing potential safety hazards is achieved.
