Abstract

A low-speed bidirectional regulating type hydraulic buffer comprises a shell, a cylinder body and a piston rod, wherein a spring is arranged between the other end of the piston rod and a contact; damping holes are respectively arranged at two ends of a sliding sleeve in the shell; the left end of the cylinder body and the right end of an end cover are respectively provided with regulating points; the sliding sleeve is matched with an adjusting screw rod on the cylinder body; and the shell is provided with a retainer ring and a mounting flange. In the utility model, the opening regulation of the damping holes can be realized as follows: the sliding sleeve moves horizontally along the axial direction by regulating the adjusting screw rod, the standstill between the cylinder body and the shell is realized by a guide pin, and the cylinder body and the end cover can rotate simultaneously by a linkage pin, therefore, the opening regulation of the damping holes can be conducted on the regulating points at two ends of the buffer respectively or simultaneously, and the buffering speed of the buffer can realize bidirectional double-point regulation; and two ends of the buffer are designed with the mounting flange and the retainer ring, thus realizing the adjustable buffering speed and bearing capacity, and selectable regulation methods and installation methods.

Description

Low-speed bidirectional regulating hydraulic buffer
Technical field
The utility model relates to a kind of motion buffering that is applicable to metallurgy, engineering machinery and crane gear, and buffer is realized the buffering purpose by the damped motion of hydraulic oil mixed medium in enclosed cavity.
Background technique
Mechanical damping device and hydraulic bjuffer are that auxiliary device is very widely used in metallurgy, engineering machinery and Hoisting Machinery field, existing buffer mostly is certain fixed equipment specialized designs, its buffer speed, bearing capacity are generally non-adjustable, and mounting type is single, and versatility is not strong.
Summary of the invention
The utility model purpose provides and a kind ofly is applicable to the buffer speed that use in metallurgy, engineering machinery and Hoisting Machinery field and bearing capacity is adjustable, regulative mode and the optional multipurpose low speed of mounting type buffer.
The purpose of this utility model is achieved in that a kind of low-speed bidirectional regulating hydraulic buffer, comprise housing, be provided with cylinder body in the housing, piston rod one end is positioned at cylinder body, is connected by set bar between cylinder body and the end cap, is provided with guide finger between cylinder body and the housing, be provided with spring between the piston rod the other end and the contact, flip sleeve two ends in the housing are respectively equipped with damping hole, are respectively equipped with point of adjustment at cylinder body left end and end cap right-hand member, and flip sleeve matches with adjusting screw rod.Housing is provided with collar.Housing is provided with mounting flange.
The low-speed bidirectional regulating hydraulic buffer that the utility model provides is with the hydraulic oil mixed medium, realizes the buffering purpose by the damped motion of hydraulic medium in enclosed cavity.The damping hole aperture of this device regulate can by adjust regulate screw thread make flip sleeve vertically move left and right realize, realize spline by guide finger between cylinder body and housing, can rotate simultaneously by set bar between cylinder body and end cap, so just can respectively or carry out the damping hole aperture in the point of adjustment at buffer two ends simultaneously and regulate.The buffer speed of buffer can be realized two-way two point adjusting; Buffer two ends designs has mounting flange and collar, so just can realize that buffer speed and bearing capacity are adjustable, regulative mode and mounting type be optional.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a sectional structure schematic representation of the present utility model.
Accompanying drawing 2 is the utility model outline drawings.
Embodiment
As shown in Figures 1 and 2, the utility model comprises housing 3, be provided with cylinder body 1 in the housing 3, piston rod 4 one ends are positioned at cylinder body 1, it is characterized in that: be connected by set bar 15 between cylinder body 1 and the end cap 6, be provided with guide finger 16 between cylinder body 1 and the housing 3, be provided with spring 8 between piston rod 4 the other ends and the contact 9, flip sleeve 5 two ends in the housing 3 are respectively equipped with damping hole 10,11, are respectively equipped with point of adjustment 12,13 at cylinder body 1 left end and end cap 6 right-hand members, and flip sleeve 5 matches with adjusting screw rod 14.Housing 3 is provided with collar 2 and mounting flange 7.
The utility model working principle is as follows:
Contact 9 promotes piston rod 4 and moves from right to left under the load effect, piston extruding hydraulic oil from rodless cavity through buffer cavity to rod chamber motion (along arrow indication path), rodless cavity produces instantaneous high pressure, rod chamber produces instantaneous negative pressure, hydraulic oil produces buffer function to load during by damping hole 10 and damping hole 11, arrive at cylinder bottom up to piston, spring 8 is compressed and stored energy simultaneously; After load disappeared, spring 8 discharged kinetic energy pulling piston rod 4 and moves from left to right, and piston extruding hydraulic oil slowly moves (along arrow indication reverse path) to rodless cavity through buffer cavity from rod chamber, all discharges up to spring 8 energy, and this moment, piston rod 4 resetted.
Damping hole 10 and damping hole 11 apertures size are directly proportional with buffer speed, the damping hole aperture regulate can by adjust adjusting screw rod 14 make flip sleeve 5 vertically move left and right realize, 3 of cylinder body 1 and housings pass through guide finger 16 and realize splines, can rotate simultaneously by set bar 15 between cylinder body 1 and the end cap 6, so just can carry out damping hole 11 or the adjusting of damping hole 10 apertures in buffer two ends point of adjustment 12 and point of adjustment 13 respectively or simultaneously.
By mounting flange 7 or collar 2, buffer can adopt multiple mounting type.
