Abstract

The invention relates to a hydraulic system for synchronously and continuously conveying drill pipes with a locking function, which belongs to the technical field of hydraulic control and includes a fuel tank, a manual reversing valve, a hydraulic control reversing valve, a hydraulic lock, a diverting and collecting valve, a left lifting oil cylinder, The right lift cylinder, bracket, downstroke valve and upstroke valve; among them, the working oil port A and working oil port B of the hydraulic control reversing valve are connected with the two oil inlet ports of the hydraulic lock one by one, and the hydraulic lock's One oil outlet is connected to the rod cavity of the left lift cylinder and the right lift cylinder, the other oil outlet is connected to the oil inlet of the diverter-collector valve, and the oil outlet of the diverter-collector valve is connected to the left lift cylinder and the right lift cylinder. Rodless cavity of the liter cylinder. Through the downstroke valve and upstroke valve on and off, the bracket connected with the piston rods of the two oil cylinders is controlled to move up and down reciprocally, and the drill pipe is lifted to send it to the drill pipe box, so as to improve the drilling efficiency of the automatic drilling rig. The double oil cylinders ensure stable lifting, the diverter and flow valve ensures the synchronous action of the double oil cylinders, and the hydraulic lock enables the bracket to stay at any position within the stroke range.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control, and relates to a hydraulic system for synchronously and continuously conveying drill pipes with a locking function. Background technique [0002] In the process of coal mining, because of safety requirements, operations such as gas drainage and water exploration are often performed, and drilling operations are required for these tasks. Hydraulic drilling rigs are commonly used production equipment in coal mine gas drainage operations. The capacity of the drill pipe box of the drilling rig is limited, and the empty box of the drill pipe box will inevitably affect the working efficiency of the drilling rig. Therefore, it is necessary to invest in research on how to increase the drill pipe carrying capacity of the drilling rig, thereby improving the working efficiency of the drilling rig. Contents of the invention [0003] In view of this, the object of the present invention is to prov...
