Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] This embodiment provides a two-way buffer hydraulic cylinder, which utilizes the orifice throttling feature to realize the buffer function of the piston rod 1 during the two-way process of extension and retraction, and can realize buffer functions under various load characteristics.

[0032] like figure 1 and 2 As shown, the two-way buffer hydraulic cylinder includes: piston rod 1, cylinder head 2, outer cylinder 3, inner cylinder 4, spacer sleeve 5, throttle rod 6, one-way valve A7 and one-way valve B8.

[0033] The connection relationship of the two-way buffer hydraulic cylinder is as follows: the throttle rod 6 is a hollow tube with an opening at one end and a hole at the other end, and its internal cavity is an oil chamber D15. It is fixedly connected with one end of the outer cylinder 3 to realize the coaxial assembly of the throttle rod 6 an...

Abstract

The invention discloses a two-way buffer hydraulic cylinder, comprising: a piston rod, a cylinder body, a throttle rod and a one-way valve A; the two-way buffer hydraulic cylinder of the present invention uses a built-in throttle rod to realize two-way buffer under variable load conditions Function, only relying on its own structure can realize the buffer braking control of the speed of the moving object during the two-way movement; it can instantly absorb the huge kinetic energy of the rapid turning of the large-mass object or the rapid stop of the high-speed reciprocating movement, so that it can stop smoothly; The cylinder body of the cavity cooperates with the throttle rod with multiple throttle holes, and realizes the two-way buffer function of the piston rod during the expansion and contraction process by using the throttle characteristics of the small holes; the overall structure is compact, the performance is superior, safe, reliable and practical Strong, especially suitable for buffer braking of high-speed, large-mass, and ultra-high-energy moving objects.

Description

technical field [0001] The invention relates to the technical field of fast turning or reciprocating motion start-stop of large-mass objects, in particular to a two-way buffer hydraulic cylinder. Background technique [0002] The function of the buffer hydraulic cylinder is to push and pull a reciprocating or overturning object, especially a large-mass and fast-moving object, to make it stop smoothly and slowly, and to protect the equipment from the strong impact of the object's motion energy. At present, the commonly used buffering methods of buffering hydraulic cylinders include variable cross-section type, annular gap flow type, buffering plunger type, multi-hole throttling type, etc., but the current buffering structure can only achieve single end buffering or piston retraction. One-way buffering. At present, there is no structure that can realize the two-way process buffering of moving objects only by its own structure; [0003] The large-mass object quickly flips and...
