[0025] As Figure 1 shown, a device for detecting the propulsion pressure of an anchor drill includes a frame 1. The top of the frame 1 is fixedly connected with an anchor drill body 2, and one side of the anchor drill body 2 is fixedly connected with an oil delivery pipe 3 and an oil return pipe 4. One end of the oil delivery pipe 3 is provided with an installation component 5, and one side of the installation component 5 is provided with a sealing component 6. One side of the sealing component 6 is provided with a pressure detector 7; one side of the installation component 5 is provided with a connecting oil pipe 8;

[0026] As Figures 2 to 4 shown, the installation component 5 includes a three-way joint 501; one end of the three-way joint 501 is fixedly connected with a valve 502; the oil delivery pipe 3 is fixedly connected and communicated with the valve 502 through the three-way joint 501, and the three-way joint 501 is arranged between the oil delivery pipe 3 and the valve 502; one end of the valve 502 is fixedly connected with a sleeve 503; the three-way joint 501 is fixedly connected and communicated with the sleeve 503 through the valve 502, and the valve 502 is arranged between the three-way joint 501 and the sleeve 503;

[0027] The inside of the sleeve 503 is provided with an internal thread 504; and a solenoid tube 505 is threadedly connected inside the internal thread 504. The solenoid tube 505 is fixed on one side of the pressure detector 7. The sleeve 503 and the solenoid tube 505 form a threaded structure through the internal thread 504 to realize the connection and conduction between the pressure detector 7 and the valve 502; and the shape and size of the internal thread 504 match the shape and size of the solenoid tube 505, and the outer wall of the solenoid tube 505 is arranged in fit with the inner wall of the internal thread 504.

[0028] As Figures 2 to 4As shown, the sealing assembly 6 includes a gasket 606. The gasket 606 is arranged on the end face of the sleeve 503, and the gasket 606 is arranged between the pressure detector 7 and the sleeve 503. The pressure detector 7 and the sleeve 503 form a sealing structure through the gasket 606.

[0029] The sealing assembly 6 further includes a mounting disc 601 rotatably connected to the sleeve 503. One side of the mounting disc 601 is fixedly connected with a limiting rod 602, and one end of the limiting rod 602 is fixedly connected with a screw rod 603.

Thus, the axial locking force between the sleeve 503 and the screw pipe 505 is improved compared with only through threaded connection, and the connection stability between the sleeve 503 and the screw pipe 505 is improved, and the sealing effect is enhanced.
