Abstract

The invention discloses a remote control grab bucket capable of discharging in a stable mode, the grab bucket comprises an upper bearer and a lower bearer, the upper bearer is connected to a bucket body and a transmission apparatus, a hydraulic system is arranged at the lower bearer, the lower bearer and the bucket body enable rotatable connection, the bucket body completes opening and closing under cooperation of the transmission apparatus and the hydraulic system, the hydraulic system comprises a housing and a solenoid valve reversing valve fixed at top of the housing, an oil inlet interface of the hydraulic system and an oil outlet interface of the hydraulic system are arranged at bottom of two sides of the housing, a buffer speed regulating valve is arranged at upper part of the left side, a buffer pressure-regulating valve is arranged at upper part of the right side, a safety valve is arranged at front part, and an oil return tube is arranged in the the grab bucket. According to the invention, based on the conventional hydraulic system, the buffer speed regulating valve and the buffer pressure-regulating valve are added, large pressure is removed, then a main valve is opened, great shock generated through instant release by a high-pressure oil-way is prevented, so that stable discharging can be realized.

Description

technical field [0001] The invention relates to a mechanical device for grabbing and unloading goods, in particular to a remote control grab bucket for stable unloading. Background technique [0002] The grab bucket is a loading and unloading mechanical component suitable for transportation places such as railway freight yards, mines, and docks, and is used for loading and unloading bulk goods. The hydraulic grab is a working device that provides power for the hydraulic cylinder through the hydraulic power source, thereby driving the opening and closing of the left and right combined buckets or multiple jaw plates to grab and discharge bulk materials. The remote control grab is a hydraulic grab that cooperates with a single-rope crane to control the opening and closing through a wireless remote control transmitter. [0003] For the purpose of saving energy and reducing the heating of the hydraulic system of the hydraulic grab, no matter what control method is adopted, the c...
