Description

Quick connector of excavator

Technical Field

The utility model relates to the technical field of engineering machinery, in particular to a quick connector of an excavator.

Background

The excavator is used as the most common engineering machinery for daily construction and bears various operation functions. The multifunctional tool is also widely applied, and the quick connector is used as a connecting tool of an excavator and operation devices (such as a bucket, a breaking hammer and a hydraulic shear), so that the quick switching installation of various operation devices is realized, the application range of the excavator is enlarged, the waste of time and labor caused by replacing an accessory dismounting pin shaft is avoided, and the working efficiency is improved. The most commonly used quick connectors at present are hydraulic cylinder type quick connectors and screw mechanical quick connectors:

the hydraulic cylinder type quick connector is characterized in that one end of the hydraulic cylinder is used for supporting the lock hook, the other end of the hydraulic cylinder type quick connector is hinged with the main hook body, a whole set of pipeline is needed to be installed for supplying oil to the cylinder, the cylinder stretches out and draws back to enable the lock hook to be tensioned through the reversing electromagnetic valve, technical installation or manual installation cost is needed to be required for installation, the installation of the hydraulic cylinder type quick connector is about 5 hours, if the situation that spare parts are not matched is met, the hydraulic cylinder is used for a year normally, oil leakage and pressure relief of the cylinder exist, oil seal abrasion or aging phenomenon in the cylinder are caused, damaged oil leakage can occur after the pipeline is used for a long time, the phenomena of valve blocking and coil short circuit burning are easy to occur to the electromagnetic valve, great trouble is brought to users, the stroke of the main hook body and the lock hook design cylinder can only be within 60mm, the main hook body cannot reach or easily break, and only two auxiliary devices can be correspondingly replaced, the upper part of the design of the main hook body is transversely installed on the main hook body through a shaft, the lower part is provided with the cylinder support to push the lock hook to be subjected to downward pulling force and backward pushing force when working, and the shaft on the lock hook is easily broken.

The main part of the mechanical quick connector of the lead screw is that the lead screw is matched with a lead screw barrel to twist, so that the supporting lock hook stretches out and draws back, but the mechanical lead screw is respectively subjected to the impact force of three surfaces because of the design principle of the main hook body and the lock hook, so that the problem that the lead screw is easy to drop or break after being used for a period of time is solved, the failure rate is higher, the manual wrench is required to twist hard, the time is longer, the time is wasted, and the labor is wasted, if severe construction environments are met, such as: the screw can not be screwed up easily in the screw barrel of the conditions such as pond, silt, etc., and the driver gets back and forth to go down the excavator and twist the screw many times, and the stroke of main hook body and latch hook design hydro-cylinder can only be within 60mm, and too long then can not reach and easily fracture, and just can correspond to change two kinds of auxiliary equipment.

Therefore, an excavator quick connector is provided to solve the existing shortages.
