The utility model belongs to the field of electric power overhaul auxiliary equipment, and particularly relates to auxiliary equipment for installing a current transformer. Comprising a placing platform used for placing a current transformer; the placement platform is located on the horizontal centering mechanism, and a transverse movement module and a longitudinal movement module on the horizontal plane are arranged on the centering mechanism; the lifting mechanism is located below the alignment centering mechanism; the current transformer is placed on the placing platform, and rapid installation can be carried out after connecting holes in the upper side and the lower side of the current transformer and installation holes in an installation plate in a switch cabinet are centered through the lifting mechanism and the horizontal centering mechanism. And the placing platform, the horizontal centering mechanism and the lifting mechanism are carried on the walking mechanism. And the traveling mechanism can complete the required transfer in the mounting process.

The utility model discloses a hydrostatic pressure test device for a water supply pipe. The hydrostatic pressure test device for the water supply pipe comprises a test main body, a water pumping pipe, a multi-stage mounting joint and a pressing mechanism, the multi-stage mounting connector is arranged on the first side of the test main body, the water pumping pipe is connected with the test main body and is communicated with the multi-stage mounting connector through the test main body, the pressing mechanism is arranged on the first side of the test main body, the pressing mechanism is arranged above the multi-stage mounting connector, and the pressing mechanism can tightly press the multi-stage mounting connector in a sealing mode. The test main body can detect the water pressure passing through the multi-stage mounting joint. According to the device, through the arrangement of the multi-stage mounting joints, water supply pipes of different models and the test device can be mounted, and through the arrangement of the multi-stage mounting joints, joints of different models do not need to be used. Moreover, due to the arrangement of the pressing mechanism, when the multi-stage mounting joint of the test device is connected with the water supply pipe, the pipe and the multi-stage mounting joint can be pressed and fixed through the pressing mechanism, so that the pipe is prevented from falling off.

This utility model discloses a plate adjustment mechanism for a sheet-fed offset printing press, relating to the field of offset printing plate technology. It includes a plate roller with sliders at both ends. A drive motor is controlled to rotate a driving gear above a support plate, causing the driving gear to rotate a driven gear. This, in turn, causes the driven gear to drive a lead screw to rotate on the inner wall of the support plate, thereby driving the sliders to slide up and down on the inner wall of the support, adjusting the distance between the plate roller and the transfer roller. This ensures better printing on single sheets of paper by the offset printing press. A protective post is fixed to the top of the support plate, and a connecting plate slides on top of the protective post. A limiting post, fixed at the bottom of a fixing plate, is fitted onto the inner wall of a horizontal plate, allowing the bottom of the limiting post to engage with the inner wall of the support plate. This provides protection for the outer walls of the driving and driven gears mounted above the support plate, ensuring stable up-and-down adjustment of the plate roller on the outer wall of the support.

The utility model discloses an assembly structure of a safety belt sliding plate, which relates to the technical field of safety belt sliding plates and adopts the technical scheme that the assembly structure comprises a sliding plate body, assembly shells are arranged at the top and the bottom of the sliding plate body, two sliding rods are fixedly arranged between the two assembly shells and penetrate through the sliding plate body, and a decorative plate is arranged on one side of the sliding plate body. Clamping shells are arranged on the two sides of the assembling shell and fixedly connected with the decorative plate, and an assembling assembly is arranged in the assembling shell. The assembling assembly comprises two vertical plates, the two vertical plates are fixedly arranged in the assembling shell, a threaded rod is connected between the two vertical plates through bearings, the screwing directions of threads on the two sides of the outer portion of the threaded rod are opposite, clamping blocks are arranged on the two sides of the outer portion of the threaded rod through threads in a sleeving mode, the clamping blocks extend out of the assembling shell, and the clamping blocks are buckled with the clamping shell. The safety belt sliding plate is convenient to maintain, can be adjusted up and down smoothly, and is convenient to slide and adjust.
