Subdivision excavator quick connector

Published by HuiTong 2023-12-20

Excavator quick connector, also known as quick-change connectors. Excavator quick connector can quickly install various configuration accessories on the excavator, such as buckets, rippers, breakers, hydraulic shears, wood grabs, stone grabs, etc., which can expand the scope of excavators, save time, and improve work efficiency. 

 

One: Classification of quick connectors for excavators:

Excavator quick connector joints are divided into mechanical and hydraulic types.

Two: Brief introduction of excavator quick connector:

(1) Use high-strength materials, South Korea uses 20M high-strength panels, and China uses Q345B panels;

(2) Suitable for various models of 4-50 tons;

(3) Use the safety device of hydraulic control check valve to ensure safety;

(4) The configuration parts of the excavator can be replaced without modification and without disassembling the pin shaft, so the installation is quick and the work efficiency can be greatly improved.

 

Three: Working principle of hydraulic excavator quick connector joint:

The hydraulic excavator quick connectorjoint is mainly used to fix and release the pins 1 and 2 by the action of the oil cylinder. When working parts need to be replaced, the oil cylinder is retracted, the hook-shaped clamp moves from position 1 to position 2, and the quick-change coupling is disengaged and replaced with other working parts. After the hook-shaped clamp is aligned with the pin, the cylinder is opened again. , The hook-shaped pressing block moves from position 2 to position 1 to lock the pin of the working fitting. Of course, except for this, there are external oil circuits and solenoid valves working at the same time.

Four: Working principle of mechanical excavator quick connector joint:

The products of various manufacturers of mechanical excavator quick connector are mainly divided into two types, one pin type and the other screw type. Take the bolt type as an example. When you need to replace the working parts, first pull out the wedge card and knock the T-shaped buckle in. (The T-shaped buckle can smoothly drive the red part of the press block to recycle, where the welding requirements are relatively high. , The slide rail is not welded and flat, and if it is not polished cleanly, the red part of the pressing block will hardly move smoothly.) The quick-change joint is separated from the bucket. When the required working parts are changed, the T-shaped buckle is pulled back, and the wedge-shaped card is inserted into the T-shaped buckle to lock.
