Special hoisting tool for replacing capacitor bank

Abstract

The invention discloses a special hoisting tool for replacing a capacitor bank. The special hoisting tool comprises two landing leg sleeves; a connection rod and a bracket are arranged between the two landing leg sleeves; each landing leg sleeve is respectively provided with a transverse supporting sleeve; a gear box is arranged between the two supporting sleeves; a second lead screw is arranged in the two transverse supporting sleeves and the gear box and is provided with a second bevel gear and two extension rods; the two supporting sleeves are respectively provided with a landing leg; the bracket is fixedly provided with a support seat; a first lead screw and a guide rod are fixedly installed between the support seat and the connecting rod; one end of the first lead screw is provided with a rocker and the other end of the first lead screw is provided with a first bevel gear, and the two bevel gears are engaged; the guide rod is provided with a sliding seat on which a nut is installed; the nut is in threaded connection with the first lead screw; the sliding seat is fixedly provided with a hinge seat on which a suspension arm support rod is arranged; the upper end of the suspension arm support rod is provided with a suspension arm; a hydraulic cylinder is installed between the suspension arm support rod and the suspension arm; a support rod is installed on the suspension arm support rod; and the support seat is provided with a positioning groove matched with the lower end of the support rod.

Description

technical field [0001] The invention relates to a special hoisting tool for replacing capacitor banks. Background technique [0002] For a long time, the problem of difficult capacitor bank replacement has always plagued the ultra-high voltage power transmission and transformation industry. The main reason is: when replacing the capacitor bank, the equipment to be replaced needs to be hoisted and removed first, and then the new equipment should be hoisted to the original position; All kinds of existing hoisting machines cannot enter the capacitor bank installation space for effective hoisting. Therefore, until now, the work of hoisting equipment has been done manually by several strong and well-coordinated staff, and the replacement process is time-consuming. It is laborious, and it is very easy for the staff to cooperate improperly, and the suspended capacitor bank equipment falls and injures the staff or smashes the accident of the capacitor bank, which brings huge econom...

[0002] For a long time, the problem of difficult replacement of capacitor banks has always plagued the ultra-high voltage power transmission and transformation industry

The main reason is: when replacing the capacitor bank, the equipment to be replaced needs to be hoisted and removed first, and then the new equipment should be hoisted to the original position; All kinds of existing hoisting machines cannot enter the capacitor bank installation space for effective hoisting. Therefore, until now, the work of hoisting equipment has been done manually by several strong and well-coordinated staff, and the replacement process is time-consuming. It is laborious, and it is very easy for the staff to cooperate improperly, and the suspended capacitor bank equipment falls and injures the staff or destroys the capacitor bank, which brings huge economic losses and personnel losses to the ultra-high voltage power transmission and transformation enterprises.

In addition, it is not possible to determine whether the equipment in the capacitor bank needs to be replaced before the maintenance. During the work process, there will be a phenomenon that a single person is assigned to repair the capacitor bank at first, and when it is found that the capacitor bank equipment needs to be replaced, it is necessary to contact other maintenance personnel to send additional manpower. , or at the beginning, a number of staff members were assigned to overhaul the capacitor bank, but it was found that the capacitor bank equipment did not need to be replaced, and it could be repaired by a single person. Ultra-high voltage power transmission and transformation enterprises need to keep a large number of idle workers in case of insufficient manpower when replacing capacitor banks, which greatly reduces work efficiency and increases operating costs
