[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Example

[0017] See also Figures 1 to 4, the present invention provides a technical solution: a resistance-sensing drill pipe pushing device, which includes a vertical column, a conveying guide rail 1, a pneumatic-assisted gripper 2, a propulsion unit 3, a pressure transmitter 4, and an operating platform 5. A rack 11 is provided inside the conveying guide rail 1. The operating platform 5 and the vertical column are respectively located on both sides of the conveying guide rail 1. A connecting device is provided between the vertical column and the conveying guide rail 1. The pneumatic-assisted gripper 2 and the propulsion unit 3 are respectively arranged at both ends of the conveying guide rail 1. The propulsion unit 3 includes a traveling reduction gearbox 31, a traveling motor 32, an air inlet and outlet 33 of the propulsion unit, and a rod storage groove 34. The pressure transmitter 4 is placed in the rod storage groove 34, and a circular groove for placing the drill pipe is provided on the pressure transmitter 4. The operating platform 5 includes an air source inlet 51, a first air inlet and outlet 52, a second air inlet and outlet 53, a second manual reversing valve 54, a first manual reversing valve 55, a hydraulic pressure gauge 56, and an air pressure gauge 57. The pressure transmitter 4 is connected to the hydraulic pressure gauge 56 through a connecting pipeline. When the propulsion unit 3 advances forward, the magnitude of the thrust can be observed through the reading of the hydraulic pressure gauge 56. The pressure transmitter 4 can monitor the pressure of the propulsion unit 3 in real time during the pushing process. Through this pressure, the situation of the explosive at the end of the ejector rod can be judged. When the pressure is too high, there may be abnormalities in the hardness of the coal seam where the explosive is located at the end of the ejector rod, and it is necessary to stop the machine for inspection.

[0018] In this embodiment, preferably, the traveling reduction gearbox 31 is connected to the traveling motor 32, and the air inlet and outlet 33 of the propulsion unit is arranged on one side of the traveling motor 32, and the rod storage groove 34 is arranged above the traveling reduction gearbox 31.

[0019] In this embodiment, preferably, the air source inlet 51 is arranged at the inner bottom end of the operating platform 5. The second manual reversing valve 54 and the first manual reversing valve 55 are symmetrically arranged. The first air inlet and outlet 52 and the second air inlet and outlet 53 are symmetrically arranged on both sides of the air pressure gauge 57. The first air inlet and outlet 52 is connected to the air inlet and outlet on the pneumatic-assisted gripper 2 through a connecting pipeline. By operating the second manual reversing valve 54 on the operating platform 5, the clamping and opening of the pneumatic-assisted gripper 2 can be realized. The second air inlet and outlet 53 is connected to the air inlet and outlet 33 of the propulsion unit through a connecting pipeline. By operating the first manual reversing valve 55 on the operating platform 5, the up and down movement of the propulsion unit 3 can be realized. The air source inlet 51 of the operating platform 5 is connected to the mine's intake pipe, and the working air pressure range of the operating platform 5 is 0.4 - 0.63 MPa.

[0020] In this embodiment, preferably, the connecting device includes a fixed locking sleeve installed on one side of the conveying guide rail 1. The other end of the fixed locking sleeve is fixed on the surface of the vertical column. The conveying guide rail 1 is connected to the vertical column through the fixed locking sleeve, thereby stabilizing the whole machine. A pusher and a push rod stabilizer are also provided on the conveying guide rail 1. The push rod stabilizer is located between the pusher and the pneumatic-assisted gripper 2 and can move along with the push rod on the conveying guide rail 1 to facilitate the drill pipe to smoothly enter the pneumatic-assisted gripper 2.

[0021] The pressure transmitter 4 in this device is a high-precision and high-sensitivity detection instrument. The pressure transmitter 4 is placed in the rod storage groove 34 of the propulsion unit 3. When drilling, the drill pipe is placed at the circular groove of the pressure transmitter 4 to start working. When the propulsion unit 3 moves forward, as the number of drill pipes increases, the force on the propulsion unit 3 increases, and the greater the pressure received by the pressure transmitter 4. As the pressure increases, the hydraulic fluid inside the pressure transmitter 4 is compressed to a certain extent, generating a certain hydraulic pressure. The hydraulic pressure is displayed by the reading of the pressure gauge 56 connected to the pressure transmitter 4. There is a safety protection pressure relief device inside this pressure transmitter 4 to prevent damage to the instrument due to excessive force.

[0022] All the connecting pipelines in this device are made of high-quality and high-grade pneumatic rubber hoses, which can efficiently and reliably ensure the normal operation of the mechanism.

[0023] The working principle and usage process of the present invention:

[0024] First step: Control the handle of the first manual reversing valve 55 on the control console 5 to place the propulsion unit 3 in the lowest position;

[0025] Second step: Control the handle of the second manual reversing valve 54 on the control console 5 to release the pneumatic assist gripper 2;

[0026] Third step: Place the drill pipe. When placing the drill pipe, directly place it at the circular groove in the pressure transmitter 4 in the rod storage groove 34;

[0027] Fourth step: Control the handle of the first manual reversing valve 55 on the control console 5 to move the propulsion unit 3 forward to the limit position;

[0028] Fifth step: Control the handle of the second manual reversing valve 54 on the control console 5 to clamp the pneumatic assist gripper 2;

[0029] Sixth step: Control the handle of the first manual reversing valve 55 on the control console 5 to move the propulsion unit 3 backward to the lowest position;

[0030] In this way, by repeating the above second to sixth steps, the purpose of continuous drilling can be achieved.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
