Hydraulic grab driven by diesel through wireless remote control

Abstract

The invention relates to a hydraulic grab driven by a diesel through wireless remote control. The hydraulic grab comprises a hoisting ring, a shackle, an outer shell, a through girder, two bucket bodies, a hydraulic device and a wireless remote control device, wherein the hydraulic device is provided with a hydraulic pump, an oil cylinder, and a control valve block system, the oil cylinder is connected with the hydraulic pump by a solenoid valve and is driven by the hydraulic pump through power provided by the diesel connected with the hydraulic pump, and two ends of a connecting rod are respectively connected at the inner side edges of the two bucket bodies through pin rolls so as to play a position limiting and protecting role in closing and opening of the grab. The grab can be remotely controlled to grab cargoes or when no power is available, the oil cylinder can be driven to close or open the grab to grab the cargoes, and the hydraulic grab is applicable to poor working environments, can work regardless of high frequency service conditions, is long in work service life, improves the efficiency of enterprises, overcomes potential safety hazards of the production and is convenient to operate.

Description

technical field [0001] The invention relates to a grab bucket used for bulk cargo loading and unloading, in particular to a radio-controlled diesel engine-driven hydraulic grab bucket used on single-cable hoisting equipment to grab bulk cargo of various specific gravity. Background technique [0002] The electro-hydraulic grab is an important component of lifting equipment, but because the crane is often in harsh working environments such as high temperature and humidity, dust, sea salt spray, etc., the lifting speed is fast and the lifting frequency is high, especially when the cable is pulled There is a large pulse tension, and the thinner control line in the cable that controls the work of the grab is easy to be broken after a long time. Breaking the cable will cause great economic losses to the enterprise and even bring great economic losses. Potential safety hazards. Some cranes are not equipped with power supply systems, so they cannot provide electro-hydraulic grab po...

[0002] The electro-hydraulic grab is an important component of lifting equipment, but because the crane is often in harsh working environments such as high temperature and humidity, dust, sea salt spray, etc., the lifting speed is fast and the lifting frequency is high, especially when the cable is pulled There is a large pulse tension, and the thinner control line in the cable that controls the work of the grab is easy to be broken after a long time. Breaking the cable will cause great economic losses to the enterprise and even bring great economic losses. Potential safety hazards. Some cranes are not equipped with power supply systems, so they cannot provide electro-hydraulic grab power and cannot grab goods.
