Abstract

The invention discloses an elastic buffer of a festoon cable. The elastic buffer comprises a cylinder body with a piston cavity and a piston rod in the piston cavity, wherein the piston rod is used for dividing the piston cavity into a rod cavity and a rodless cavity and comprises a guide ring and a sliding rod which is fixedly connected with the guide ring; hydraulic oil is filled in the rodless cavity, and the rod cavity is internally provided with a tension spring; the guide ring is provided with a first communicating hole and a second communicating hole, the first communicating hole is internally provided with a first one-way valve which can prevent the hydraulic oil in the rodless cavity from entering the rod cavity, and the second communicating hole is internally provided with a second one-way valve; when the pressure of the hydraulic oil in the rodless cavity reaches the opening pressure of the second one-way valve, the hydraulic oil enters the rod cavity. The elastic buffer provided by the invention has the advantages that the structure is simple, the manufacture is easy, the service life is long, and the buffering effect is good.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an elastic buffer for a cable trolley or a cable trolley. Background technique [0002] The Chinese utility model patent with patent application number CN201220217072.8 and application date: 2012-05-15 discloses a cable block, including a mounting seat, a wheel set on the mounting seat, and a cable rack on the mounting seat. A protective block is provided on the side of the mounting seat; the distance between the corresponding side of the cable frame and the middle section of the cable trolley parallel to the side of the cable frame is smaller than the distance between the protective block and the middle section. This kind of cable pulley is provided with a protection block, and this protection block is exactly a buffer, and it protects the cable frames of the two cable pulleys from colliding when two cable pulleys collide. However, the existing elastic buffers are ge...
