The invention belongs to the technical field of walking beam type steel coil transport, discloses a hydraulic control valve stand of a walking beam type steel coil transportation device, and is used for a transverse moving hydraulic cylinder and a lifting hydraulic cylinder. The hydraulic control valve stand of the walking beam type steel coil transport device comprises an electro-hydraulic directional valve, a first double-hydraulic-control one-way valve, a double-one-way throttle valve, a double-overflow valve, a first proportional direction valve, a first hydraulic-control one-way valve, a second hydraulic-control one-way valve, a first overflow valve, a second overflow valve, a first one-way valve, a second proportional direction valve, a third hydraulic-control one-way valve, a fourth hydraulic-control one-way valve, a third overflow valve, a fourth overflow valve, a second one-way valve and an electromagnetic directional valve. According to the hydraulic control valve stand of the walking beam type steel coil transport device, the function of a large-drift-diameter proportional valve can be achieved through a small-drift-diameter proportional valve assembly, and the technical effect of stably and reliably achieving hydraulic control over the walking beam type steel coil transport device is achieved.
Description
technical field [0001] The invention relates to the technical field of walking beam type steel coil transportation, in particular to a hydraulic control valve table of a walking beam type steel coil transportation device. Background technique [0002] In the strip processing line, the walking beam coil transport device is one of the very important process equipment. In order to meet the large load requirements of the walking beam, hydraulic cylinders are usually used to drive the lifting and lateral movement of the walking beam. In order to ensure the stability and safety of the lifting and lateral movement of the walking beam, a large-diameter proportional valve group must be used to control the lifting and lateral movement of the hydraulic cylinder; however, the price of the large-diameter proportional valve is expensive, and its diameter specification is Level, the price will increase exponentially, so the cost of the hydraulic control valve table of the walking beam typ...
