[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-4 As shown, this example provides a lever-type propulsion mechanism, including: a propulsion beam 100, a propulsion assembly 200, and a transfer assembly 300.

[0022] The propulsion beam 100 has guide rails 101 on both sides along its length. The propulsion assembly 200 includes a support plate 201 mounted on the guide rails 101 and movable along its length. The support plate 201 has a power output shaft 202 that rotates around its own axis. Below the power output shaft 202, there is a bearing plate 203 that moves along its axis. The transfer assembly 300 includes a support plate 301 mounted on the propulsion beam 100 for abutting against the top surface of the bearing plate 203. The support plate 301 has a bracket 302 that moves along its length. The bracket 302 has two connecting shafts 303 arranged sequentially. One connecting shaft 303 has a push rod at its end, and the other connecting shaft 303 has a drill rod at its end. One side of the support plate 301 has two coaxially arranged and synchronously rotating first levers 304 for pushing the bracket 302. One end of the support plate 301 has two coaxially arranged and synchronously rotating second levers 305 for pushing the connecting shafts 303 onto the bearing plate 203.

[0023] Specifically, the power output shaft 202 is rotatably mounted on the side plate 209 and connected to the output end of the first power device. The first power device is mounted on the side plate 209, which is mounted on the support plate 201. The end of the power output shaft 202 is provided with a transmission shaft 210. The side wall of the transmission shaft 210 is provided with multiple spaced positioning pins 211 along the circumferential direction. The inner wall of the connecting shaft 303 is provided with multiple positioning grooves 317 along the circumferential direction. When the connecting shaft 303 is located on the support plate 203, the positioning pins 211 are engaged in the positioning grooves 317. At this time, the power output shaft 202 is driven to rotate by the first power device, which will drive the connecting shaft 303 to rotate. The support plate 201 moves synchronously along the length direction of the guide rail 101, thereby realizing the pushing operation of the top rod or drill rod.

[0024] Specifically, the support plate 203 is sleeved on the connecting rod 204, and both ends of the connecting rod 204 are mounted on the convex plate 205. The convex plate 205 is mounted on the support plate 201. A spring 206 is sleeved on the connecting rod 204. The two ends of the spring 206 abut against the support plate 203 and the convex plate 205 located below, and are always in a compressed state. Under the action of the spring 206, the support plate 203 always tends to move towards the power output shaft 202. After the connecting shaft 303 is placed on the support plate 203, the support plate 201 is moved along the length direction of the guide rail 101. Under the action of the spring 206, the support plate 203 will move relative to the support plate 201, thereby ensuring that the transmission shaft 210 enters the connecting shaft 303 and the two mesh.

[0025] Specifically, the support plate 203 is provided with a groove 207 that extends through one end, and limiting grooves 208 are provided on both sides of the groove 207 along its length direction. The connecting shaft 303 is provided with two retaining rings 306. When the connecting shaft 303 is transferred to the support plate 203, the retaining rings 306 cooperate in the limiting grooves 208 to provide limiting and support for the connecting shaft 303.

[0026] Specifically, the support plate 301 has a through groove 307 along its length, and sliding grooves 308 are provided on both sides of the through groove 307 along its length. When the connecting shaft 303 is located on the bracket 302, the retaining ring 306 is engaged in the sliding groove 308. The through groove 307 has a notch 309 on the side near the bearing plate 203. The sliding groove 308 extends to the outer end of the notch 309. When the support plate 301 abuts against the top surface of the bearing plate 203, the spring 206 is further compressed, and the connecting shaft 303 and the power output shaft 202 are separated. The notch 309 is aligned with the groove 207 and is used to pass through the connecting shaft 303 so that the connecting shaft 303 can move back and forth between the bearing plate 203 and the support plate 301.

[0027] Specifically, the bracket 302 is slidably fitted in the through groove 307. The bracket 302 includes two U-shaped parts with the openings of the U-shaped parts facing the notch 309. The connecting shaft 303 is located in the U-shaped part, and the retaining rings 306 are located on the upper and lower sides of the U-shaped part respectively, so as to facilitate the transfer of the connecting shaft 303 from the bracket 302 to the support plate 203.

[0028] Specifically, both ends of the bracket 302 are provided with protruding rods 310. The inner side of the first lever 304 contacts the inner side of the protruding rod 310. The first lever 304 is mounted on the first rotating ring 311. The first rotating ring 311 is mounted on the first rotating shaft 312. The first rotating shaft 312 is rotatably mounted on the support plate 301 and connected to the output end of the second power device. The second power device is mounted on the support plate 301. When it is necessary to transfer the connecting shaft 303, the first rotating shaft 312 is driven to rotate by the second power device. Then the first lever 304 will rotate synchronously and force the bracket 302 to move along the length direction of the through groove 307 until one of the U-shaped parts is aligned with the notch 309. At this time, the connecting shaft 303 can be transferred to the bearing plate 203 by the second lever 305.

[0029] Specifically, the second lever 305 is mounted on the second rotating ring 313, which is sleeved on the second rotating shaft 314 with a keyway fit. The second rotating ring 313 is rotatably mounted on the moving ring 315, which is connected to the moving end of the telescopic mechanism. The telescopic mechanism is mounted on the horizontal plate 316, one end of which is connected to the support plate 301, and the other end is mounted on the push beam 100. The second rotating shaft 314 is rotatably mounted on the horizontal plate 316 and connected to the output end of the third power device. The third power device is mounted on the horizontal plate 316 when it is necessary to... When the connecting shaft 303 moves back and forth between the bearing plate 203 and the bracket 302, the telescopic mechanism drives the moving ring 315 to move toward the horizontal plate 316, so that the connecting shaft 303 is located between the two second levers 305. At this time, the second rotating shaft 314 is driven to rotate by the third power device, which in turn drives the second levers 305 to rotate, thereby moving the connecting shaft 303 back and forth between the bearing plate 203 and the bracket 302. In order to avoid affecting the smooth movement of the propulsion component 200, the second levers 305 are located above the support plate 301 during the movement of the pallet 201.

[0030] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
