Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bidirectional steering oil cylinders, in particular to a bidirectional steering oil cylinder for aerial work. Background Art
[0002] The working principle of the bidirectional oil cylinder is mainly realized by the pressure difference of the hydraulic oil. When the hydraulic pump inputs the hydraulic oil into one of the piston chambers, the hydraulic oil forms a certain pressure in the piston chamber, and this pressure pushes the piston to the other piston chamber. At the same time, the hydraulic oil in the other piston chamber is squeezed and the pressure increases. In this way, the piston will move toward the other piston chamber, thereby achieving a push-pull effect. The bidirectional steering oil cylinder refers to a bidirectional oil cylinder specially used for steering in aerial work.
[0003] After searching, the patent with announcement number CN208236806U discloses a two-way oil cylinder for fitness equipment, and its content records "including an outer cylinder body, an inner cylinder body, a piston rod, a decorative sleeve and a rear end cover, the decorative sleeve is connected to the front end of the outer cylinder body, the rear end cover is connected to the rear end of the outer cylinder body, and a front end cover is also arranged in the outer cylinder body, the front end cover has a horizontal through hole for the piston rod to insert and a vertical connecting hole for connecting the adjusting rod, the vertical connecting hole and the horizontal through hole are connected, an adjusting hole for the adjusting rod to extend out is opened on the outer cylinder body, and a limiting member for preventing the adjusting rod from falling out is arranged between the front end cover and the outer cylinder body. It sets the adjusting rod on the front end cover, and at the same time avoids adjustment through the limiting member..." From the above, it can be seen that the piston rod of the two-way oil cylinder of the patent has a limited range of movement, cannot be adjusted, and has a small range of use, which has certain shortcomings.
