Abstract

The invention relates to a low-speed bidirectional regulating hydraulic buffer which 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, a damping hole is respectively arranged at both ends of a sliding sleeve in the shell, a regulating point is respectively arranged at the left end of the cylinder body and the right end of an end cover, and the sliding sleeve is matched with a regulating screw on the cylinder body. A clamp ring and a mounting flange are arranged on the shell. The opening regulation of the damping holes can be realized through regulating the regulating screw to enable the sliding sleeve to move left and right along an axial direction, the rotation stop between the cylinder body and the shell is realized through a guide pin, and the cylinder body and the end cover can be simultaneously rotated through a linked pin, thus, the opening regulation of the damping holes can be carried out respectively or simultaneously at the regulating points at both ends of the buffer, and bidirectional double-point regulation can be realized for the buffering speed of the buffer; the mounting flange and the clamp ring are designed at both ends of the buffer, thereby realizing the regulation of the buffering speed and the bearing capacity and the selection of a regulating mode and a mounting mode.

Description

technical field [0001] The invention relates to a motion buffer suitable for metallurgy, engineering machinery and hoisting equipment. The buffer realizes the purpose of buffering through the damping motion of a hydraulic oil mixed medium in a closed cavity. Background technique [0002] Mechanical buffers and hydraulic buffers are widely used auxiliary devices in the fields of metallurgy, engineering machinery and hoisting machinery. Most of the existing buffers are specially designed for certain fixed equipment. The buffering speed and carrying capacity are generally not adjustable, and the installation method is single. , the versatility is not strong. Contents of the invention [0003] The purpose of the present invention is to provide a multi-purpose low-speed buffer with adjustable buffer speed and bearing capacity, optional adjustment mode and installation mode, which is suitable for applications in the fields of metallurgy, engineering machinery and hoisting machin...
