Problems solved by technology

Because the replacement of the seals and wear-resistant parts on the cylinder end cover and piston requires the removal of the nut on the piston rod to fix the piston, and the tightening torque of the cylinder nut used in large-scale equipment is very large, which makes disassembly and assembly very difficult

Embodiment Construction

[0021] see Figure 1-Figure 12 , the present invention has a base 1, the key technology of which is that the base 1 is combined into a frame structure by section steel, the ear end brackets 2 are respectively installed through bolts 7 on both sides of one end of the base 1, and the turntable 3 is installed between the ear end brackets 2, and the turntable 3. It is composed of an inner disc 11 with a rectangular hole in the center and an outer disc 12 with shaft holes evenly distributed on the outer ring. The turntable 3 is connected with the ear end bracket 2 by a pin shaft 10 through the shaft hole. The rectangular hole in the center of the turntable 3 is used to cover the On the ear end of the piston rod, the distance between the shaft holes of the outer disk 12 can be determined according to the jack stroke, and at least one hole distance can be rotated at a time when jacking up; The upper welding bracket ring 13 constitutes the rod end bracket 5, and a wrench 6 is installe...

Abstract

The invention belongs to the field of the manufacturing and maintenance of engineering construction equipment, and in particular relates to a device of a fixture for maintaining a large-scale hydraulic oil cylinder. According to a key technology, the device comprises a base; the base has a frame structure which is formed by combining profile steel; lug end supports are arranged on two sides of one end of the base respectively, and a rotary table is arranged between the lug end supports; support frames are arranged on two sides of the other end of the base respectively; support circular rings are subjected to assembly welding on the support frames to form rod end supports; a wrench is arranged between the rod end supports; and a jack is arranged below the end of a wrench rod on the base. The device has the advantages that the device is suitable for disassembling and assembling oil cylinder piston nuts of different specifications, and is particularly suitable for the on-site maintenance of oil cylinders of large-scale and ultra large-scale hydraulic equipment, and multiple oil cylinder piston nuts can be disassembled and assembled only by using one platform. By using the platform for disassembling and assembling an oil cylinder piston, the labor intensity is reduced greatly, and the platform is convenient to install in the using process, high in progress, high in replacement efficiency, high in quality, safe and reliable.

Description

technical field [0001] The invention belongs to the field of manufacturing and maintenance of engineering construction equipment, in particular to a large-scale hydraulic oil cylinder maintenance tooling device. Background technique [0002] Large-scale engineering construction will inevitably use large-scale and ultra-large-scale engineering construction equipment, and timely maintenance of construction site equipment is particularly important. Hydraulic equipment accounts for the vast majority of large-scale construction equipment, and it is common to replace hydraulic seals and wearing parts on site, such as hydraulic cylinders. Because the replacement of seals and wear-resistant parts on the cylinder end cover and piston requires dismantling the nuts that fix the piston on the piston rod, and the tightening torque of the cylinder nuts used in large equipment is very large, making disassembly and assembly very difficult. Contents of the invention [0003] The problem t...
