Closing coil overhaul apparatus of electromagnetic mechanism

Abstract

The invention discloses a closing coil overhaul apparatus of an electromagnetic mechanism. The closing coil overhaul apparatus comprises a jack and universal wheels; the jack consists of a bracket, athreaded rod and a hand-rocking handle; the bracket comprises four supporting rods which are connected end to end, wherein the connecting positions are hinged and fixed through a first hinged column,a second hinged column, a third hinged column and a fourth hinged column respectively; one end of the threaded rod is connected with the hand-rocking handle while the other end passes through the first hinged column and then is connected with the third hinged column; an upper connecting fixed sheet is arranged in the fixed position of the second hinged column; a lower connecting fixed sheet is arranged in the fixed position of the fourth hinged column; a fixed frame is welded on the upper connecting fixed sheet; a connecting plate is welded at the lower end of the lower connecting fixed sheet;and the universal wheels are arranged on the connecting plate. By virtue of the closing coil overhaul apparatus, the working apparatus of the closing coil overhaul apparatus of the electromagnetic mechanism is greatly improved, and in addition, the electromagnetic mechanism is relatively low in manufacturing cost.

Description

Technical field: [0001] The invention relates to a closing coil overhauling device, in particular to an electromagnetic mechanism closing coil overhauling device. Background technique: [0002] During the operation of the electromagnetic mechanism, the defect of the auxiliary switch node often causes the closing coil to be burned, and the working members must replace the closing coil of the electromagnetic mechanism many times, but the process of disassembling the bottom of the electromagnetic mechanism is complicated and inconvenient, especially when the coil is replaced. In the subsequent recovery work, the bottom of the electromagnetic mechanism has a ground clearance of 40 cm, and there are closing coils and iron cores inside, weighing about 30 kilograms. The entire closing coil replacement process is time-consuming and labor-intensive, and it takes at least 30 minutes to complete. Because the electromagnetic mechanism weighs up to 30 kilograms, the staff will be exhaust...

Problems solved by technology

[0002] During the operation of the electromagnetic mechanism, the defect of the auxiliary switch node often causes the closing coil to be burned, and the working members must replace the closing coil of the electromagnetic mechanism many times, but the process of disassembling the bottom of the electromagnetic mechanism is complicated and inconvenient, especially when the coil is replaced. In the subsequent recovery work, the bottom of the electromagnetic mechanism has a ground clearance of 40 cm, and there are closing coils and iron cores inside, weighing about 30 kilograms. The entire closing coil replacement process is time-consuming and labor-intensive, and it takes at least 30 minutes to complete. Because the electromagnetic mechanism weighs up to 30 kilograms, the staff will be exhausted after lifting for a long time. If they are not careful, they will be injured by the electromagnetic mechanism, or the new closing coil in the electromagnetic mechanism will be damaged, which will affect the progress of the work.

[0003] And due to the internal structure of the electromagnetic mechanism, in order to ensure the successful assembly of the electromagnetic mechanism, the travel rod of the iron core must be aligned with the stroke groove before installing the screws for fixing. Generally, four people are required to cooperate to replace the electromagnetic mechanism, and two people are responsible for it. To level the bottom of the electromagnetic mechanism, one person is responsible for aligning the stroke rod of the iron core with the stroke groove, and the last person fixes the bottom screw. The stamina and physical strength of the staff also need the tacit agreement of four people. Two people hold the bottom of the electromagnetic mechanism to ensure its stability. At the same time, one person is responsible for aligning the iron core stroke rod with the stroke groove. Screws can be fixed, but the progress of these operations is made more difficult due to the small space where the electromagnetic mechanism can move close to the switch cabinet
