A square key is installed on the first drive shaft 1105, and a square slot corresponding to the key is formed on the second engagement ring, ensuring that the second engagement ring can still slide along the first drive shaft 1105 even when rotating with it. The first and second engagement rings engage through teeth at their ends.

[0042] The second pulley 1108 is coaxially sleeved on the first drive shaft 1105 and fixedly connected to the first clutch 1107. The second pulley 1108 rotates with the first engagement ring. The second pulley 1108 is connected to the fourth pulley 1306 of the lifting assembly 13 via the second drive belt. The second pulley 1108 is a small pulley.

[0043] The first sprocket 1109 is coaxially mounted on the second end of the first drive shaft 1105, and the first sprocket 1109 rotates with the first drive shaft 1105. The first sprocket 1109 is a small sprocket.

[0044] The second drive shaft 1110 is mounted on the frame 1103 and can rotate around a horizontal line. The second drive shaft 1110 and the first drive shaft 1105 are arranged parallel to each other on the same plane.

[0045] The second sprocket 1111 is coaxially mounted on the second end of the second drive shaft 1110. The second sprocket 1111 is connected to the first sprocket 1109 via a drive chain, and the second sprocket 1111 drives the second drive shaft 1110 to rotate. The second sprocket 1111 is a large sprocket.

[0046] The second clutch 1112 includes a third engagement ring and a fourth engagement ring, both coaxially mounted on the second transmission shaft 1110. The third engagement ring slides relative to the second transmission shaft 1110 in the circumferential direction, while the fourth engagement ring meshes with the second transmission shaft 1110. The fourth engagement ring rotates with the second transmission shaft 1110, while the third engagement ring does not. The fourth engagement ring can slide along the second transmission shaft 1110 and engage or disengage with the third engagement ring, driving the third engagement ring, which is engaged with it, to rotate. A square key is installed on the second transmission shaft 1110, and a square slot corresponding to the key is formed on the fourth engagement ring, ensuring that the fourth engagement ring can still slide along the second transmission shaft 1110 even when rotating with it. The third and fourth engagement rings engage through teeth at their ends.

[0047] The wire rope drum 1113 is coaxially sleeved on the second drive shaft 1110 and fixedly connected to the third engagement ring. The wire rope drum 1113 rotates with the third engagement ring. The wire rope drum 1113 is connected to the wire rope 1301 of the hoisting assembly 13.

[0048] The clutch lever 1114 engages or disengages the second engagement ring from the first engagement ring, and engages or disengages the fourth engagement ring from the third engagement ring.

[0049] The main function of the frame assembly 11 is to support the lifting assembly 13 and the hammering assembly 12, and after completing the single-point probing operation, the whole machine can be moved to the next probing operation point with manual assistance.

[0050] See Figures 9-12 The hammer assembly 12 includes a hammer 1203, a slide 1201, a slide bar 1202, a third drive shaft 1204, a third pulley 1205, a lower sprocket 1206, an upper sprocket 1207, a chain 1208, and a slide bar 1202.

[0051] The slide 1201 is mounted on the frame and can slide up and down. The slide 1201 is connected to the wire rope 1301 of the lifting assembly 13. The slide 1201 has an upper support plate and a lower support plate, and the two vertical rods of the square frame are respectively embedded in the grooves on both sides of the upper and lower support plates. The steel chisel 2 is embedded in the U-shaped groove of the lower support plate.

[0052] The slide rod 1202 is vertically mounted on the upper support plate and the lower support plate of the carriage 1201. The slide rod 1202 includes two rods arranged side by side.

[0053] The hammer 1203 is used to hammer the steel chisel rod 2. The hammer 1203 is slidably mounted on the slide rod 1202.

[0054] The third drive shaft 1204 is mounted on the slide 1201 and can rotate around a horizontal line. The third drive shaft 1204 is arranged parallel to the first drive shaft 1105 on the same plane.

[0055] The third pulley 1205 is sleeved on the third drive shaft 1204 and is fixedly connected to the third drive shaft 1204. The third pulley 1205 is connected to the fourth pulley 1306 of the lifting assembly 13 via the third drive belt, and the third pulley 1205 drives the third drive shaft 1204 to rotate.

[0056] The lower sprocket 1206 is coaxially sleeved on the third drive shaft 1204 and fixedly connected to the third drive shaft 1204. The lower sprocket 1206 rotates with the third drive shaft 1204.

[0057] The upper sprocket 1207 is mounted on the frame and can rotate around a horizontal line.

[0058] Chain 1208 drives and connects lower sprocket 1206 and upper sprocket 1207. A detonator is mounted on chain 1208, which actuates the counterweight 1203. The detonator is a hook mounted on one side of chain 1208. The hook contacts a stop on the counterweight 1203, causing the counterweight 1203 to rise to the top of the carriage 1201 and then disengage from the stop.

[0059] The main function of the hammer assembly 12 is that when the chain 1208 rotates, the chain 1208 drives the hammer 1203 to rise to the top of the slide 1201 and then disengages from the hammer 1203. The hammer 1203 falls freely and hammers the drill rod 2. As the sprocket rotates, the hammer 1203 moves up and down to continuously hammer the drill rod 2. At the same time, the slide 1201 of the hammer assembly 12 moves down continuously under its own weight until the probing operation is completed.

[0060] See Figures 13-14The lifting assembly 13 is used to transmit the driving force of the drive motor 1104 to the hammer assembly 12 and the counterweight 1203, thereby driving the hammer assembly 12 and the counterweight 1203 to move up and down. The lifting assembly 13 includes a wire rope 1301, a fixed pulley 1302, an upper swing arm 1303, a lower swing arm 1304, a pin 1305, and a fourth pulley 1306.

[0061] The wire rope 1301 connects the wire rope drum 1113 and the slide 1201.

[0062] Fixed pulley 1302 is installed on the side and top of the frame and on the carriage 1103, and can rotate around a horizontal line. Fixed pulley 1302 supports wire rope 1301. The main function of fixed pulley 1302 is to change the direction of wire rope 1301 led out from wire rope drum 1113, so as to ensure that wire rope 1301 is smoothly connected to the upper part of the slide 1201 of hammer assembly 12.

[0063] The upper part of the upper swing arm 1303 is sleeved on the third drive shaft 1204, and the upper swing arm 1303 and the third drive shaft 1204 slide relative to each other in the circumferential direction of the third drive shaft 1204. The upper swing arm 1303 includes two arms arranged side by side.

[0064] The lower part of the lower swing arm 1304 is sleeved on the first drive shaft 1105, and the lower swing arm 1304 and the first drive shaft 1105 slide relative to each other in the circumferential direction of the first drive shaft 1105. The lower swing arm 1304 includes two arms arranged side by side.

[0065] Pin 1305 rotatably connects the lower part of upper swing arm 1303 and the upper part of lower swing arm 1304. Pin 1305, upper swing arm 1303 and lower swing arm 1304 slide relative to each other in the circumferential direction of pin 1305.

[0066] The fourth pulley 1306 is coaxially mounted on the pin 1305. The fourth pulley 1306 is connected to the second pulley 1108 via the second transmission belt, and to the third pulley 1205 via the third transmission belt. The fourth pulley 1306 is a double-groove pulley.

[0067] The main function of the aforementioned lifting assembly 13 is to, after the drive motor 1104 of the frame assembly 11 starts running, rotate the first pulley 1106 via belt drive, and transmit the power output of the drive motor 1104 to the upper hammer assembly 12 via the second pulley 1108 and the fourth pulley 1306. At the same time, the first sprocket 1109 and the second sprocket 1111 drive the wire rope drum 1113 to rotate, and the upper hammer assembly 12 can be lifted to the initial working height via the wire rope 1301.

[0068] With the above configuration, the frame assembly 11, lifting assembly 13, and hammering assembly 12 are integrated together. A drive motor 1104 is mounted on the lower part of the frame assembly 11. After the drive motor 1104 starts running, it controls the second clutch 1112 to close via the clutch lever 1114. The wire rope drum 1113 rotates and winds in the wire rope 1301, driving the hammering assembly 12 to rise to the working height. Then, the second clutch 1112 is opened via the clutch lever 1114, and the first clutch 1107 is closed. As the drive motor 1104 runs, the first pulley 1106 on the upper part of the belt-driven frame 1103 rotates, and then the lifting assembly 12 is lifted via the belt. The fourth pulley 1306 in the middle of the upper and lower swing arms 1304 of the lifting assembly 13 rotates. The fourth pulley 1306 is connected to the third pulley 1205 at the lower part of the hammer assembly 12. The third pulley 1205 at the lower part of the hammer assembly 12 is also mounted on the same drive shaft as the lower sprocket 1206, ultimately providing the operating power for the lower sprocket 1206 of the hammer assembly 12. As the lower sprocket 1206, upper sprocket 1207, and chain 1208 of the hammer assembly 12 rotate, the hammer 1203 will be driven to reciprocate up and down to continuously hammer the drill rod 2. At the same time, the slide 1201 of the hammer assembly 12 moves down continuously under its own weight, ultimately realizing the probing operation.

[0069] Specifically, after the power is turned on and the drive motor 1104 starts to run, as the second clutch 1112 closes, the wire rope drum 1113 starts to rotate and winds in the wire rope 1301. The hammer assembly 12 is finally lifted to the required working height through the fixed pulley 1302 and then the power is turned off. At this time, the steel chisel 2 is installed and the second clutch 1112 is released. Power is reconnected, and the motor reverses via the control button. The first clutch 1107 is engaged via the clutch lever 1114, causing the first engagement ring and second pulley 1108 to rotate. Simultaneously, the fourth pulley 1306 of the belt-driven lifting assembly 13 begins to rotate. The third pulley 1205, lower sprocket 1206, upper sprocket 1207, and chain 1208 of the hammering assembly 12 begin to rotate, driving the hammer 1203 upwards along the slide bar 1202. Upon reaching the highest point, the hammer 1203 disengages from the chain 1208 and begins to fall freely, striking the drill rod 2. As the chain 1208 rotates, the hammer 1203 is continuously lifted and then falls freely, ultimately completing the hammering of the drill rod 2. During the hammering process, the hammering assembly 12 falls continuously under its own weight, and the upper swing arm 1303 and lower swing arm 1304 swing with the falling hammering assembly 12, ultimately completing the single-point probing operation. After the single-point probing operation is completed, the first clutch 1107 is released to stop hammering, the second clutch 1112 is closed, the wire rope drum 1113 begins to wind in the wire rope 1301 and drives the hammering assembly 12 and the steel rod 2 to be lifted, and then manually moved to the next working point.
