A suspension tool for lifting springs

Abstract

The invention provides a hanger fixture for hoisting a spring. The hanger fixture comprises a hanging base plate, wherein the direction, corresponding to the circumferential direction of a to-be-hoisted spring, of the hanging base plate is defined as the circumferential direction of the hanging base plate; the direction, corresponding to the radial direction of the to-be-hoisted spring, of the hanging base plate is defined as the radial direction of the hanging base plate; the hanging base plate is pivoted with more than two hinging arms capable of swinging along the radial direction of the hinging base plate; the lower ends of the hinging arms are provided with hook heads used for hooking spiral spring silks of the spring, the more than two hinging arms are uniformly distributed along the circumferential direction of the hinging base plate, the hook heads on the lower ends of the hinging arms are respectively bent outwards in a manner of departing from each other. Because the hook heads on the lower ends of the hinging arms are respectively bent outwards in a manner of departing from each other, when the spring is hoisted, each hoisting arm is capable of stretching into the spring, and when each hinging arm is strutted along the radial direction of the hoisting base plate, the hooking heads at the lower ends of each hinging arms hook the spiral spring silks of the spring from the interior, and then the spring is upward hoisted, so that the transfer of the spring is finished. The hoisting tool is positioned in the spring during a hoisting process, the hoisting tool is relatively low in hoisting space requirement and high in universality.

Description

technical field [0001] The invention relates to a hanger tool for lifting a spring. Background technique [0002] In the technical field of high-voltage electrical equipment, it is often necessary to assemble springs inside the barrel to play the role of energy storage and buffering. Due to the large size and weight of some springs, it is time-consuming and labor-intensive for workers to carry, and it is not easy to grasp the balance, and the assembly accuracy cannot be guaranteed. It needs to go back and forth many times for adjustment. The labor intensity of the workers and the assembly efficiency are low. [0003] A Chinese utility model patent with the authorized announcement number CN201102857Y discloses a spring transportation device, which includes a suspension plate, on which a plurality of booms evenly distributed around the circumference are pivotally connected, and each boom extends along the up and down direction , the upper end of the boom is pivotally connecte...

AI Technical Summary

Problems solved by technology

[0004] When using the above-mentioned spring transportation device to hoist the spring into the tube, because the hooks at the lower end of the boom are all bent inward, the above-mentioned spring transportation device can only hook the spring from the outside of the spring. Due to space constraints, it is not impossible to enter the assembly tube. , that is, after the hoisting is completed, the boom cannot be opened to realize decoupling, and the spring transport device cannot be separated from the spring, which requires a relatively high installation space, resulting in the lack of versatility of the above spring transport device
