Problems solved by technology

[0002] At present, for some workpieces whose axial center of gravity is difficult to determine, there is no suitable spreader on the market, such as pot insulators. In many high-voltage electrical products, it is inevitable to use pot insulators to separate each air chamber. Among them, pot insulators When connected in a horizontal manner, due to the unique concave-convex structure of the pot insulator itself and the different parts installed on the concave-convex surface, it is difficult to ensure the parallelism of the butt joint surfaces during the docking process of lifting the pot insulator, which will cause certain problems for installation and disassembly. difficult, and it is easy to cause bumps on the sealing surface of the pot insulator, which affects its assembly quality

Embodiment Construction

[0015] a spreader, such as Figure 1-2 As shown, it includes a hanger, and the hanger includes an arc-shaped connecting plate 1 for bonding with the end face of the pot insulator and a guide rail 2 connected to the connecting plate 1 through a connecting bolt 4 at one end. The guiding direction of the guide rail 2 In the same direction as the axis of the pot insulator, a lifting device connector 3 is installed on the guide rail 2 for guiding movement. The arc-shaped connecting plate 1 is provided with 7 connection holes 5 at intervals along its circumferential direction, which are used to fix and connect the pot insulator. The pot insulator is embedded with a double-screw screw, and the axis direction of the double-screw screw is the same as the pot The axial direction of the insulator is the same and runs through the two end faces of the pot insulator. The connecting hole 5 and one end of the double-screw head screw are fixedly connected by a nut to fix the pot insulator on t...

Abstract

The invention relates to a lifting appliance. The lifting appliance comprises a lifting frame. The lifting frame comprises a connecting structure used for being fixedly connected with a to-be-hoisted workpiece, and a guiding structure with the guiding direction the same as the direction of the axis of the to-be-hoisted workpiece. A hoisting device connecting piece connected with a hoisting device is assembled on the guiding structure in a guiding and moving manner. The lifting appliance further comprises a fixing structure used for fixing the position of the adjusted hoisting device connecting piece. By moving the hoisting device connecting piece assembled on the guiding structure in the guiding and moving manner many times, a proper hoisting point is determined, the position of the hoisting device connecting piece is fixed through the fixing structure, and it is guaranteed that in the hoisting process, the axis of the to-be-hoisted workpiece is horizontal and hoisting of the to-be-hoisted workpiece is smooth and stable.

Description

technical field [0001] The invention relates to a sling. Background technique [0002] At present, for some workpieces whose axial center of gravity is difficult to determine, there is no suitable spreader on the market, such as pot insulators. In many high-voltage electrical products, it is inevitable to use pot insulators to separate each air chamber. Among them, pot insulators When connected in a horizontal manner, due to the unique concave-convex structure of the pot insulator itself and the different parts installed on the concave-convex surface, it is difficult to ensure the parallelism of the butt joint surfaces during the docking process of lifting the pot insulator, which will cause certain problems for installation and disassembly. It is difficult, and it is easy to cause bumps on the sealing surface of the pot insulator, which affects its assembly quality. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings in...
