Description

Technical Field

[0001] The utility model relates to the technical field of partial dismantling of a servomotor, in particular to a device for dismantling a cylinder cover of a guide vane servomotor. Background Art

[0002] When repairing the relay, the relay cylinder head needs to be removed. At present, when dismantling the above equipment, there are no special tools and it can only be removed manually. It is difficult to remove the relay cylinder head by manual removal, and it is time-consuming and labor-intensive. Even inaccurate operation may cause equipment damage and seriously reduce work efficiency. When reinstalling, it is impossible to correctly position the piston rod and the relay cylinder head, and it is difficult to install the cylinder head in place, which affects the maintenance of the relay cylinder head. According to previous maintenance experience, the removal of the relay cylinder head is done by pulling it out diagonally with two hoists at the upper end and forcibly pulling it out with a horizontal hoist. The copper sleeve and piston rod in the cylinder head are easily scratched. There are many safety hazards due to on-site conditions, and it takes a long time and has high labor costs. To this end, we propose a guide vane servo cylinder head removal device to solve the above-mentioned problems. Utility Model Content
