Abstract

The invention relates to a synchronous and continuous drill rod conveying hydraulic system, and belongs to the technical field of hydraulic control. The synchronous and continuous drill rod conveying hydraulic system comprises an oil tank, a manual reversing valve, a hydraulic control reversing valve, a flow distributing and collecting valve, a left lifting oil cylinder, a right lifting oil cylinder, a bracket, a lower stroke valve and an upper stroke valve, wherein a working oil port A of the hydraulic control reversing valve is connected with rod cavities of the left lifting oil cylinder and the right lifting oil cylinder, a working oil port B of the hydraulic control reversing valve is connected with an oil inlet of the flow distributing and collecting valve, and an oil outlet of the flow distributing and collecting valve is connected with rodless cavities of the left lifting oil cylinder and the right lifting oil cylinder. Through on-off of the lower stroke valve and the upper stroke valve, the bracket connected with piston rods of the two oil cylinders is automatically controlled to ascend and descend in a reciprocating manner, a drill rod is lifted and conveyed into a drill rod box of an automatic drilling machine, and the drilling efficiency of the automatic drilling machine is improved. The double oil cylinders are adopted so that stable lifting of the drill rod conveying system can be guaranteed, the flow distributing and collecting valve guarantees synchronous action of the two oil cylinders, and stable conveying of the drill rod is guaranteed.

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. 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 provide a hydraulic system f...
