Description

A kind of buffer unit for Head end of cable pulley
Technical field
The present invention relates to logistics equipment technical field, more specifically to a kind of buffering for Head end of cable pulley is filled Put.
Background technology
Number of patent application be CN 201310558776.0, the applying date be 2013.11.12 Chinese invention patent disclose A kind of elastic buffer for cable trailing, including the cylinder body with plunger shaft, the piston rod in the plunger shaft, The plunger shaft is divided into rod chamber and rodless cavity by the piston rod, and the piston rod includes guide ring and solid with the guide ring Surely the sliding bar connected, filled with hydraulic oil in the rodless cavity, is provided with extension spring in the rod chamber, the guide ring is provided with the It is provided with one intercommunicating pore and the second intercommunicating pore, first intercommunicating pore and prevents the hydraulic oil in the rodless cavity from having described in Second check valve is installed, when the pressure of hydraulic oil in the rodless cavity in the first check valve in rod cavity, second intercommunicating pore So that the hydraulic oil enters the rod chamber when reaching the second unidirectional valve opening pressure.
But, the elastic buffer is complicated, and fault rate is higher in real work.
The content of the invention
It is an object of the invention to provide with a kind of buffer unit for Head end of cable pulley, prior art can be overcome Weak point, its structure is novel, and easy to make, with low cost, fault rate is low, good buffer effect.
The present invention is achieved by the following technical solutions, a kind of buffer unit for Head end of cable pulley, including peace Fill plate, in addition to be located on the installing plate mounting seat, be located in the mounting seat the first sliding cavity, be located at described first The first sliding bar in sliding cavity, the first buffer gear for entering row buffering to first sliding bar and described first are slided The second sliding cavity that dynamic chamber is communicated and the second buffer gear being located in second sliding cavity.
Preferably, second buffer gear includes slip crash panel, the fixation point being located in second sliding cavity Cut multiple mounting holes that plate is located on the fixed fragmenting plate and the sliding plunger being located on the mounting hole, the fixation point Cut and the closed chamber full of grease is formed between plate and the second sliding cavity bottom surface.
Preferably, provided with cunning in the radial cavity that the mounting seat is provided with and the closed chamber is communicated, the radial cavity Motion block, the disc spring for adjusting plug screw and being located between sliding shoe, regulation plug screw.
Preferably, the quantity of the disc spring is 5-8.
Preferably, described first slides boom end provided with block rubber.
Preferably, first buffer gear includes compression spring.
In summary, the invention has the advantages that:
Simple in construction, easy to make, with low cost, operating efficiency is high, and fault rate is low, good buffer effect.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
