Embodiment Construction

[0010] like figure 1 and figure 2 As shown, the power faucet of the preferred embodiment of the present invention includes a power faucet 10 , a hydraulic motor 20 and a hydraulic drive system 30 . The hydraulic drive system 30 is used to power the hydraulic motor 20 . The hydraulic motor 20 is fixed on the power faucet 10 .

[0011] The power faucet 10 includes a housing 11 , a flush tube 12 , a central tube 13 and a gooseneck 14 . The flushing tube 12 is disposed in the casing 11 . The central tube 13 and the gooseneck 14 are respectively connected to two ends of the flushing tube 12 and communicated with the flushing tube 12 , and the central tube 13 can rotate relative to the flushing tube 12 . The other end of the central pipe 13 is connected to a drilling tool (not shown), and the other end of the gooseneck 14 is connected to a hose (not shown). Drilling fluid can flow in from the hose, after passing through the gooseneck 14, the flushing pipe 12 and the center pip...

Abstract

The invention relates to a power water tap. The water tap comprises a washing pipe and a central pipe communicated with the washing pipe and capable of rotating relative to the washing pipe. The power water tap also comprises a variable pump, a hydraulic motor, a first reversing valve, a second reversing valve and a container, wherein the hydraulic motor is used for driving the central pipe to rotate; the first end of the variable pump is connected with a port P of the first reversing valve and a port T of the second reversing valve; the second end of the variable pump is connected with a port T of the first reversing valve; a port P of the second reversing valve is connected to the container; a port A is connected with a control port X1 of the first reversing valve; a port B is connected with a control port X2 of the first reversing valve; the port A and the port B of the first reversing valve are connected with the hydraulic motor; and a port Y is connected with the container. The power water tap is driven by a hydraulic system and the output volume of the variable pump can be adjusted continuously, so that stepless speed regulation of the power water tap can be realized.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a power water tap of the drilling machine. Background technique [0002] The existing power faucet direct drive system includes a faucet, a frequency conversion motor, an electrical control system and a reduction box. The faucet includes a casing, a flushing pipe arranged in the casing, and a center pipe that communicates with the flushing pipe and can rotate relative to the flushing pipe. The central pipe is fixedly connected with the drilling tool. The variable frequency motor is connected with the reduction box, and the reduction box is used to transmit the power of the variable frequency motor to the central tube and reduce the transmission speed. The electrical control system is used to control the variable frequency motor. When the frequency conversion motor is working, the center pipe is driven to rotate through the reduction box, thereby driving the drilling tool to rotate. When i...
