Quick-change device capable of automatically conducting hydraulic and electrical channels

Abstract

The invention discloses a quick-change device capable of automatically conducting hydraulic and electrical channels. The quick-change device comprises an upper connecting frame and a lower connectingframe. The upper connecting frame comprises a machine frame, a signal rod, a supporting rod, hydraulic push rods, a valve body, hydraulic quick-plug female ends, electrical quick-plug female ends, spring bolts, a fender and a bracket. The lower connecting frame comprises a lower machine frame, hydraulic quick-plug male ends and electrical quick-plug male ends, the hydraulic push rods are installedin the valve body, and the telescopic ends of the hydraulic push rods are fixed to the machine frame; and the hydraulic quick-plug female ends, the electrical quick-plug female ends and the spring bolts are fixed to the valve body. By operating the quick-change device, the purpose of easily and quickly replacing different working accessories can be achieved; and meanwhile, automatic conducting ofa hydraulic oil way and a control circuit between a main machine and the lower connecting working accessory is achieved, and the quick-change device is particularly important to be applied to some high-risk environments and special working conditions.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a quick-change device used in conjunction with hydraulic excavators, engineering robots and other hosts to replace different work attachments. Background technique [0002] With the development of society, people increasingly hope to use robots to replace themselves to complete those boring, heavy and dangerous tasks, such as slag breaking, stripping and cleaning of brick kilns and smelting furnaces in cement, steel and other industrial industries. In special working conditions such as dismantling, handling, sorting, shipping, and some underwater conditions in nuclear energy facilities with strong radiation and chemical industries involving highly toxic liquids and gases, engineering robots and some After the transformation, hydraulic excavators and other equipment are used for operations. In order to meet the different work needs of users, different types of work ...

AI Technical Summary

Problems solved by technology

In order to meet the different work needs of users, different types of work attachments need to be replaced frequently during construction, such as some hydraulic hammers, hydraulic grabs, hydraulic rammers, hydraulic shears, hydraulic saws, etc. To connect oil circuits and control signals, etc., it is usually achieved by driving the equipment into a safe area, using hydraulic quick change and manual loading and unloading of oil pipes and circuits, which is time-consuming and laborious. In some environments such as underwater and nuclear radiation, relying on human Going to the scene to change equipment, this kind of operation method is almost difficult to realize, and it is very easy to cause accidents such as personal injury
