Problems solved by technology

However, when two-way push-pull is required in many cases, two hydraulic cylinders need to be set back to back, but in some cases the equipment space is limited, so the layout will waste unnecessary space or weaken the strength of the equipment

Embodiment Construction

[0015] exist figure 1 In , piston rod 1 (2) is a piston rod that pushes and pulls to the left. Piston rod 2 (4) is a piston rod that pushes and pulls to the right. The lower chambers of the piston rods on both sides are connected, and the upper chambers are independent of each other. In use, the liquid supply to the lower chamber is controlled by the reversing valve, and the opening and closing of the independent upper chamber is adjusted at the same time to realize the push-out action of a single piston rod. By opening the lower chamber, liquid is supplied to each independent upper chamber to realize the pull-back action of the piston rod. After both sides are extended, such as Figure II shown.

Abstract

The invention discloses a bidirectional single-flexible hydraulic cylinder which is characterized in that a guide cylinder body and a set of piston rods with opposite directions are additionally arranged inside the single-flexible hydraulic cylinder through an overlapping method, and the piston rods extend out from holes in the rear side of an external cylinder body. Meanwhile, a lower cavity is shared through a method of providing a communicating hole in the guide cylinder body, thus the single flexing capable of being bidirectionally independently controlled is realized. Meanwhile, through regulating the acting area of one piston rod, the bad pressurizing effect is avoided.

Description

Technical field [0001] The invention relates to a bidirectional single-telescopic hydraulic cylinder, in particular to a hydraulic cylinder capable of realizing bidirectional telescopic function in a small space. Background technique [0002] At present, domestic and foreign hydraulic cylinders perform push-pull operations in one direction. Whether they are single-telescopic or double-telescopic, they are generally divided into fixed ends and movable ends. After the fixed ends are fixed, the movable ends can perform push-pull actions. However, when two-way push-pull is required in many cases, two hydraulic cylinders need to be set back to back, but in some cases the equipment space is limited, so the layout will waste unnecessary space or weaken the strength of the equipment. Contents of the invention [0003] The present invention overcomes the above disadvantages, and provides a bidirectional single telescopic hydraulic cylinder capable of bidirectional push-pull action,...
