Problems solved by technology
After the oil cylinder is used for a long time, the various joints of the oil cylinder will wear more seriously, which will seriously affect the service time of the oil cylinder
Moreover, the piston rod of the current oil cylinder will come out of the cylinder during use, or the piston rod will interact with the inner sleeve that prevents the piston rod from coming out of the cylinder during use. After a period of use, the The connection between the inner sleeve and the cylinder is unstable, which will make the piston rod out of the cylinder and affect the service time

Embodiment Construction
[0016] Combine below figure 1 and figure 2 Specific description embodiment:
[0017] Such as figure 1 and figure 2 As shown, the upper luffing oil cylinder includes a cylinder body 1 and a piston rod 2. One end of the cylinder body 1 is connected with a cylinder head 3 through a pin shaft. The cylinder body 1 is provided with a piston rod 2, and the piston rod 2 One end of the piston rod is connected with the rod head 4 through the pin shaft, and the other end of the piston rod 2 is arranged in the cylinder body 1, and a slider 5 is arranged at this end, and the slider 5 can move along the cylinder under the drive of the piston rod 2. The inner wall of the body 1 slides in the cylinder body 1, and one end of the slider 5 is provided with a protrusion 6, and when the protrusion 6 contacts the cylinder head 3, the protrusion 6 forms an oil inlet groove 7 with the inner wall of the cylinder body 1; the cylinder The upper part of the body 1 is provided with an oil pipe 8, an...

The invention belongs to the technical field of oil cylinder tools and particularly relates to a cylinder body mechanism of an upper derricking cylinder. The cylinder body mechanism of the upper derricking cylinder comprises a cylinder body, one end of the cylinder body is connected with a cylinder head through a pin shaft, the cylinder body is internally provided with a slider, the slider can slide in the cylinder body along the inner wall of the cylinder body, and the outer wall of a sliding sleeve is provided with an annular clamp hoop locking slot. The cylinder body mechanism of the upper derricking cylinder has the advantages that the exposed and stretching-out portion of a piston rod is effectively protected, the appearance quality of an oil cylinder is improved, the wear resistance of an oil cylinder bearing is improved, meanwhile, the pin shaft is effectively lubricated and protected, the service life of the pin shaft is prolonged, work efficiency is improved, the production cost is lowered, and the piston rod can be well prevented from being separated out of the cylinder body.
Description
technical field [0001] The invention belongs to the technical field of oil cylinder appliances, in particular to a cylinder body mechanism of an upper luffing oil cylinder. Background technique [0002] At present, domestic oil cylinder valves are firstly welded on the cylinder body with a valve seat, and then the valve is installed on the valve seat to realize oil in and out and hydraulic control; medium and high pressure cylinders are generally made of No. 45 seamless pipes. When the rated working pressure is too high and the wall thickness of the cylinder is not enough, the main method is to thicken the wall thickness of the cylinder, but at the same time, the weight of the oil cylinder itself is heavy and the cost is increased. When the current oil cylinder is in use, when the piston rod moves inside the cylinder body, some parts of the piston rod will be exposed when they enter and exit the cylinder body. After a long period of use, the exposed part of the piston rod wi...
