The utility model relates to hoisting tool technical field, especially point to a kind of carrying hoisting tool in field operation without network power supply, solve the problem of inconvenient equipment disassembly and carrying, poor assembly convenience in prior art, including crane frame and crane chassis, be equipped with middle shaft outer sleeve pipe on crane frame, be equipped with chassis central shaft on crane chassis, chassis central shaft and middle shaft outer sleeve pipe plug-in cooperation, the length of chassis central shaft is less than one half of middle shaft outer sleeve pipe length;Rotary drive mechanism is equipped between crane frame and crane chassis;Crane frame is detachably connected with lifting arm, take-up assembly and power generation component on it.Affirmative effect is: reduce assembly labor intensity, improve field deployment efficiency, chassis central shaft length is designed as less than one half of middle shaft outer sleeve pipe length, only need to lift crane frame to slightly higher than chassis central shaft height during assembly, it can be realized that chassis central shaft and middle shaft outer sleeve pipe plug-in cooperation, without auxiliary equipment, substantially improve the deployment efficiency of field operation.

An automatic sealing ring fitting device for a large-diameter spiral welded pipe hydraulic press includes a sealing platform, an axis determining mechanism, a centering drive, and a control unit. The sealing platform is located between the hydraulic press side seal and the end of the spiral welded pipe, serving to support and fix the sealing ring. The axis determining mechanism is used to calculate and determine the height H of the spiral welded pipe's central axis relative to the hydraulic press foundation based on the diameter of the spiral welded pipe to be tested. O The centering drive is used to move the sealing ring to align the center of the sealing ring with the central axis of the spiral welded pipe; the control unit is used to control the centering drive to position the center of the sealing ring on the central axis of the spiral welded pipe according to the axis determination result, so as to achieve coaxial positioning of the center of the sealing ring and the central axis of the spiral welded pipe.

This utility model discloses a marine containerized power supply, relating to the field of containerized power supply technology. The utility model includes a container body; several battery module assemblies are fixedly installed at the bottom of the container body. Each battery module assembly includes a frame, and several L-shaped support plates arranged in a linear array are symmetrically fixedly connected to opposite sides of the frame. A first baffle is fixedly connected between two L-shaped support plates at the same horizontal level, and several heat dissipation holes are evenly distributed on one side of the baffle. A first rotating shaft and a second rotating shaft are rotatably connected to the bottom of the frame. This utility model, through the use of this device, allows several batteries on the frame to be simultaneously sealed and fixed, and to be simultaneously disassembled, while avoiding the use of several bolts required for traditional battery fixing. This reduces the number of steps involved in installing several batteries, thereby reducing labor and improving the efficiency and convenience of battery installation and disassembly.
