The invention provides a modular door leaf of a fabricated civil air defense door. The modular door leaf comprises multiple frame steel channels, multiple pieces of I steel and multiple fabricated modules. The frame steel channels are sequentially connected end to end to form a closed ring. A groove formed by each frame steel channel points to the center of the closed ring, and an embedded batten is formed on each frame steel channel, so that the frame steel channels are embedded into sealing adhesive tape on a fabricated civil air defense protection airtight door and a door frame of the airtight door. The multiple pieces of I steel are arranged in the closed ring and connected with the multiple frame steel channels to form lattices. The multiple fabricated modules are used for improving the strength of the modular door leaf and detachably connected into the multiple lattices in a one-to-one correspondence mode. The fabricated civil air defense door comprises the door frame, the door leaf, the sealing adhesive tape, a locking mechanism and hinges. The door leaf is the module door leaf. The door leaf can be produced on an assembly line and portably assembled, welding procedures during manufacturing are reduced, the quality guarantee coefficient is increased, and meanwhile positioning precision is guaranteed by the adoption of modular production.

The transmission line insulation sheath installation tool is characterized in that: an insulation sheath installation tool capable of realizing buckling and gluing processes at the same time simplifies the installation work of the transmission line insulation sheath and reduce the danger of the tower rack work.

The utility model relates to a floating object remover for live overhead wires, which belongs to the technical field of floating object removers for wires, and in particular relates to a floating object remover for live overhead wires, which is mainly used for ground potential operation of overhead transmission lines at voltage levels of 66kV and above. The invention provides a high-safety and easy-to-use floating object remover for live overhead wires. The present invention comprises a supporting body, the main points of the structure of which are the upper end of the supporting body provided with an upwardly curved first arc-shaped blade, one end of the first arc-shaped blade is connected to the center of the upper end of the supporting body, the inner side of the first arc-shaped blade is a blade, and the center of the upper end of the supporting body is provided with a The first fixed ring; the lower end of the support body is provided with a second arc-shaped blade bent downward, one end of the second arc-shaped blade is connected to the center of the lower end of the support body, the inner side of the second arc-shaped blade is a blade, and the center of the lower end of the support body is provided with a second fixed ring ; The middle part of the supporting body is provided with a transverse through hole, and multiple strands of steel wires are threaded through the transverse through hole.

The invention discloses a shaped and fabricated formwork construction process used for a shear wall at an expansion and contraction joint. The construction process includes making a shaped and fabricated formwork; setting up a common formwork by using wood boards on the other side, opposite to the expansion and contraction joint, of a wall body; arranging positioning rebars at the root of the wall body of the shear wall; hoisting the shaped and fabricated formwork to one side, facing the expansion and contraction joint, of the wall body, preliminarily positioning the shaped and fabricated formwork through the rebars, and fixedly connecting the shaped and fabricated formwork with the common formwork through a wall-penetrating screw. By the shaped and fabricated formwork construction process, the problem that the expansion and contraction joint is narrow in space and high in construction difficulty is solved; personnel only needs to hoist the shaped and fabricated formwork to the side, facing the expansion and contraction joint, of the wall face, set up the common formwork on one side of a non-contraction joint of the shear wall, perform operation on an operating face and utilize the wall-penetrating screw to fix the shaped and fabricated formwork with the common formwork, so that construction difficulty and operating risk are lowered, construction efficiency is improved, and construction cycle is shortened.

The invention relates to an automatic connecting device which comprises ship units, and is characterized in that the adjacent ends of the two adjacent ship units are respectively provided with a concave pit and a longitudinal hole, wherein the concave pit is internally provided with a locating box which is internally provided with an upper clamp shell and a lower clamp shell, and the upper clamp shell and the lower clamp shell are respectively and rotatablely arranged in the locating box by an upper fixed pin and a lower fixed pin; an upper limit column and a lower limit column are respectively arranged at the upper side of the inner end of the upper clamp shell and the lower side of the inner end of the lower clamp shell; a balance weight is arranged at the inner end of the upper clamp shell; the longitudinal hole is internally provided with a telescopic oil cylinder and a locating rod; the outer end of the locating rod is provided with a ball head; the adjacent surfaces of the upper clamp shell and the lower clamp shell are respectively provided with a spherical concave pit; and in a connecting state of the two adjacent ship units, the ball head arranged at the outer end of the locating rod is inserted into the spherical concave pits arranged on the adjacent surfaces of the upper clamp shell and the lower clamp shell; and the ball head arranged at the outer end of the locating rod is clamped between the upper clamp shell and the lower clamp shell by a bolt and the like.
