In order to avoid overloading of the lifting hoist due to the excessive horizontal angle of the sling during the transfer and displacement process, the distance of each transfer and displacement is only 1.5-2 meters, and the entire disassembly process requires multiple changes The hanging position of the lifting hoist, so the traditional method of lifting, passing, disassembling, labor-intensive and low-efficiency, and the operation is carried out in the special working area of the hydraulic cylinder working room, because the ground is covered with oil, there is more safety. Hidden danger, extremely prone to injury accidents

Embodiment approach
[0066] like figure 1 and figure 2 As shown, preferably, two carriage rollers 20 and two rolling trolleys 30 are respectively provided, and the strength requirement of a single carriage roller 20 is usually able to safely carry 70% of the weight of the hydraulic cylinder 1, and the The carriage roller 20 includes a first carriage roller 21 and a second carriage roller 22 , and the rolling trolley 30 includes a first rolling trolley 31 and a second rolling trolley 32 . In step S4, the hydraulic cylinder 1 is pulled by the traction device 4 until the front end of the hydraulic cylinder 1 reaches the top of the rolling guide rail 3, then the traction is stopped to ensure that the carriage rollers 20 are not Leave the rolling platform 2; use the first rolling trolley 31 to support the front end of the hydraulic cylinder 1, remove the second bracket roller 22 at the rear end of the hydraulic cylinder 1; continue to pull the hydraulic cylinder 1 to roll, when the hydraulic cylinder...

The invention provides a dismounting method for a large horizontal type hydraulic cylinder from a restricted space. The dismounting method comprises the following steps of: arranging a rolling and transporting platform and a bracket roller, and regulating height of the bracket roller; arranging a rolling and transporting guide rail, wherein the rolling and transporting guide rail is positioned ona moving path of the hydraulic cylinder, and a rolling and transporting trolley is arranged on the rolling and transporting guide rail; arranging a traction device, and connecting the traction deviceto the front end of the hydraulic cylinder; dismounting a fixed bolt of the hydraulic cylinder, pulling out the hydraulic cylinder from a machine base through the traction device, and replacing the bracket roller with the rolling and transporting trolley to support the hydraulic cylinder when the hydraulic cylinder is rolled and transported to a position above the rolling and transporting guide rail; and pulling the hydraulic cylinder to continuously move along the rolling and transporting guide rail through the traction device until the hydraulic cylinder is completely separated from the restricted space. The dismounting method is simple, the sectionalized rolling and transporting platform and the sectionalized rolling and transporting guide rail are arranged, and the traction device pulls, so that the hydraulic cylinder does not deviate from towards the two sides while moving, and therefore, dismounting labor intensity is reduced, and dismounting efficiency is improved.
Description
technical field [0001] The invention relates to the field of maintenance of mechanical equipment, in particular to a method for disassembling a large horizontal hydraulic cylinder in a limited space. Background technique [0002] All kinds of large hydraulic cylinders are indispensable and important equipment in the production of metallurgical industry. During the frequent use of hydraulic cylinders, the plunger rods, sealing rings and other components in the cylinder body of the hydraulic cylinder will inevitably wear and damage. Cylinder disassembly, inspection and maintenance are necessary links to ensure the daily safe operation of hydraulic equipment. In the dismantling and maintenance of large hydraulic cylinders, removing tens of tons of hydraulic cylinders from the machine base and reinstalling the machine base after the hydraulic cylinder is repaired is an important process of hydraulic machine maintenance, labor load and safety construction. The demands are high. ...
