[0011] Furthermore, the piston oil delivery component includes piston cylinders arrayed and fixed on the inner side wall of the base. Two connecting pipes are fixedly installed at the bottom of the piston cylinders. The bottom end of one connecting pipe is connected to the side of the sealing cylinder, and the bottom end of the other connecting pipe is located inside the bottom end of the base. Both connecting pipes are equipped with one-way valves. A piston body is slidably connected inside the top of the piston cylinder. An arc-shaped plate is fixedly installed at the top of the piston body. The arc-shaped plate is attached to the circumferential surface of the rotating cylinder. A sliding ball is fixedly installed on the inner arc surface of the arc-shaped plate. V-shaped grooves are arrayed on the circumferential surface of the rotating cylinder. The top ends of the V-shaped grooves are connected through arc-shaped grooves. The sliding ball is slidably connected in the V-shaped grooves and the arc-shaped grooves.

[0012] Furthermore, the oil flow channel is provided with a flow-blocking component, which includes a transition cavity opened in a fixed shaft. The transition cavity is connected to the oil flow channel. A guide rod is fixedly installed between the top wall and the bottom wall of the transition cavity. A sealing plug is slidably connected to the guide rod. The sealing plug is inserted into the bottom end of the transition cavity where it connects with the oil flow channel.

[0013] Furthermore, the dripping assembly includes an oil storage box fixedly installed at the top of the vertical guide rail. A holding groove is fixedly installed at the center of the bottom wall of the oil storage box, and the holding groove is connected to the oil delivery channel. Four protrusions are fixedly installed at the bottom of the oil storage box. The protrusions fit against the surface of the reinforcing edging.

The valve stem is inserted into the oil drain pipe, and the top end of the valve stem is in the shape of an inverted cone. A spring is fixedly installed between the bottom end of the oil drain pipe and the inner wall of the sliding sleeve. The spring is used to drive the sliding sleeve and the valve stem to move downward and to make the valve stem seal the bottom end of the oil drain pipe. A through hole two is opened at the bottom end of the sliding sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This automated pipe laying machine, by retracting the output end of the hydraulic cylinder, reduces the distance between the upper slide and the lower slide, and decreases the angle between the upper rotating arm and the support arm, thereby causing the casing to move from right to left. The casing moves to the vicinity of the drill string, and then the second motor drives the fifth bevel gear to rotate. In conjunction with the transmission action of the third, fourth, and fifth bevel gears, the inner shaft and the sleeve rotate in opposite directions, causing the first and second grippers to deflect towards each other and clamp onto the drill string. Then, by extending the output end of the hydraulic cylinder, the clamping assembly clamps the drill string to the right. The first motor then drives the second bevel gear to rotate, thereby driving the first bevel gear, the turntable, and the vertical guide rail to rotate. This causes the clamping assembly to clamp the drill string and rotate around the vertical guide rail, transferring the drill string. Afterwards, the second motor drives the fifth bevel gear to rotate in the opposite direction, causing the first and second grippers to release the drill string. Thus, the purpose of automatically transferring the drill string is achieved. When the vertical guide rail, turntable, and fixed shaft rotate, they drive the rotating drum and extension rod to rotate synchronously. The sliding ball slides along the V-shaped groove and arc groove, driving the piston body to slide vertically. With the guidance of the connecting pipe and one-way valve, the lubricating oil inside the base is delivered to the sealing cylinder. Then, the lubricating oil passes through the through hole and enters the oil delivery channel. The lubricating oil pushes the sealing plug upward and flows upward through the gap between the sealing plug and the side wall of the transition cavity. Then, the lubricating oil passes through the oil delivery channel inside the vertical guide rail and enters the holding tank. As the amount of lubricating oil in the holding tank increases, the lubricating oil overflows from the top of the holding tank into the oil storage box. Finally, the lubricating oil in the oil storage box drips through the drip channel onto the surface of the reinforcing edge, lubricating the reinforcing edge; thus achieving the purpose of self-lubrication. When the upper slide block slides along the vertical guide rail, it rolls on the reinforced edge. The lubricating oil on the surface of the reinforced edge can pass through the oil inlet slit on the roller surface to lubricate the roller and the horizontal shaft. It can also extend through the output end of the hydraulic cylinder to drive the upper slide block to move upward, so that the roller is pressed against the sliding sleeve. The sliding sleeve and valve stem move upward, the spring is compressed, and the valve stem no longer seals the bottom end of the oil drain pipe. The lubricating oil inside the holding tank can pass through the guide pipe, drip channel two, oil drain pipe, sliding sleeve and through hole two to drip onto the oil inlet slit of the support ring, thereby achieving the purpose of further lubricating the roller.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-3The present invention provides a technical solution: an automated pipe laying machine, including a base 100, a vertical guide rail 200 rotatably connected to the top of the base 100, a sliding component 300 provided on the vertical guide rail 200, a transmission component 400 hinged to the left side of the sliding component 300, and a clamping component 500 hinged to the left end of the transmission component 400; an oil pumping component 600 is provided between the base 100 and the vertical guide rail 200, and a dripping component 700 is fixedly installed at the top of the vertical guide rail 200.

[0020] Please see Figures 2-5 The vertical guide rail 200 has four reinforcing edgings 201 welded to its four edges. The reinforcing edgings 201 support the sliding assembly 300 and allow a gap between the vertical guide rail 200 and the sliding assembly 300. A turntable 202 is fixedly installed at the bottom of the vertical guide rail 200. A sealing ring 203 is provided between the turntable 202 and the inner wall of the base 100 to seal the gap between the turntable 202 and the inner wall of the base 100.

[0021] A filter hole 204 is formed through the surface of the turntable 202. A fixed shaft 205 is fixedly installed at the center of the bottom of the turntable 202. A support ring 206 is fixedly installed on the inner wall of the base 100. A bearing 207 is fixedly installed between the inner wall of the support ring 206 and the fixed shaft 205. A filter hole 208 is formed through the surface of the support ring 206. The lubricating oil inside the base 100 is delivered to the dripping assembly 700 through the oil pump assembly 600. The dripping assembly 700 applies the lubricating oil to the reinforcing edge 201. Then, the lubricating oil drips onto the turntable 202. The lubricating oil drips through the filter hole 204 onto the support ring 206. Under the guidance of the support ring 206, the lubricating oil enters the bearing 207 for lubrication. Finally, the lubricating oil flows back into the base 100 through the filter hole 208.

[0022] A bevel gear 209 is fixedly installed at the bottom of the turntable 202. The bevel gear 209 meshes with a bevel gear 210, and the bevel gear 210 is connected to a motor 211.

[0023] Please see Figure 2 and Figure 6 The sliding assembly 300 includes a lower sliding seat 301 and an upper sliding seat 302. The lower sliding seat 301 is fixedly installed on the bottom end of the vertical guide rail 200 by bolts. The upper sliding seat 302 is slidably connected to the vertical guide rail 200. A hydraulic cylinder 303 is fixedly installed between the right side of the lower sliding seat 301 and the right side of the upper sliding seat 302. By extending and retracting the output end of the hydraulic cylinder 303, the upper sliding seat 302 is driven to slide on the vertical guide rail 200, adjusting the distance between the lower sliding seat 301 and the upper sliding seat 302. In conjunction with the transmission action of the transmission assembly 400, the distance between the clamping assembly 500 and the vertical guide rail 200 is adjusted, so that the drill string clamped by the clamping assembly 500 moves laterally.

[0024] Both the upper slide block 301 and the lower slide block 302 have inclined chamfers on their inner top edges. When the upper slide block 302 slides relative to the vertical guide rail 200, the lubricating oil on the surface of the reinforcing edge 201, guided by these chamfers, can flow into the gap between the lower slide block 301 and the vertical guide rail 200, allowing the lubricating oil to continue flowing downwards along the vertical guide rail 200 or the inner wall of the lower slide block 301. In practice, a filter cotton is laid on the top of the turntable 202 to filter the lubricating oil dripping onto it.

[0025] Mounting beams 304 are fixedly installed on the front and rear sides of both ends of the sliding seat 301 and the upper sliding seat 302. Horizontal shafts 305 are fixedly installed on both ends of the mounting beams 304. Rollers 306 are rotatably connected to the horizontal shafts 305. The rollers 306 roll against the surface of the reinforcing edging 201. An oil inlet slit is provided in the middle of the rollers 306, and a connecting block 307 is fixedly installed inside the oil inlet slit. The oil inlet slit divides the rollers 306 into front and rear parts, which are connected into a single unit by the connecting block 307. When the rollers 306 roll on the reinforcing edging 201, lubricating oil on the surface of the reinforcing edging 201 can enter between the rollers 306 and the horizontal shafts 305 along the oil inlet slit, lubricating both the rollers 306 and the horizontal shafts 305.

[0026] Please see Figure 1 and Figure 7 The transmission assembly 400 includes an upper rotating arm 401 and a lower rotating arm 402. Both ends of the upper rotating arm 401 and the lower rotating arm 402 are U-shaped. The right end of the upper rotating arm 401 is hinged to the left side of the upper slide block 302, and the right end of the lower rotating arm 402 is hinged to the front and rear sides of the upper slide block 302. A first pin 403 is fixedly installed on the left end of the upper rotating arm 401, and a second pin 404 is fixedly installed on the left end of the lower rotating arm 402. Two connecting plates 405 are hinged to the first pin 403 and the second pin 404. The connecting plates 405 are hinged to the clamping assembly 500. Specifically, the connecting plates 405 are hinged to the middle of the right side of the covering shell 501. A support arm 406 is hinged between the bottom of the upper rotating arm 401 and the left side of the lower slide block 301, and the support arm 406 passes through the lower rotating arm 402. Connecting plate 407 is hinged to pin 1 403 and pin 2 404. Cylinder 408 is hinged to the bottom of connecting plate 2 407. The bottom output end of cylinder 408 is hinged to the lower half of clamping assembly 500. In practice, the bottom output end of cylinder 408 is hinged to the lower right half of the covering shell 501.

[0027] Please see Figure 8 The clamping assembly 500 includes a cover shell 501, with U-shaped plates 502 fixedly installed at both ends of the cover shell 501. The U-shaped plates 502 are U-shaped. An embedded shaft 503 and a sleeve 504 are provided at the center of the cover shell 501. The sleeve 504 is sleeved on the outside of the embedded shaft 503. The embedded shaft 503 is rotatably connected to the U-shaped plate 502. The sleeve 504 extends into the interior of the U-shaped plate 502.

[0028] Both ends of the embedded shaft 503 are fixedly equipped with jaws 505, and both ends of the casing 504 are fixedly equipped with jaws 506. Jaws 505 and 506 can be closed to form a ring structure for clamping the drill string. Both ends of the embedded shaft 503 are fixedly equipped with bevel gears 507, and both ends of the casing 504 are fixedly equipped with bevel gears 508. A bevel gear 509 meshes between bevel gears 507 and 508. Through the transmission action of bevel gears 507, 508, and 509, the embedded shaft 503 and casing 504 rotate in opposite directions, thus causing jaws 505 and 506 to deflect towards or away from each other when the embedded shaft 503 and casing 504 rotate. A motor 510 is connected to the center of one of the bevel gears 509.

[0029] Please see Figures 4-5 and Figures 9-10 The oil pump assembly 600 includes a rotating drum 601 fixedly installed at the bottom of the fixed shaft 205. An extension rod 602 is fixedly installed at the bottom of the rotating drum 601. An oil delivery channel 603 is provided at the center of the rotating drum 601, the extension rod 602, the vertical guide rail 200, the turntable 202 and the fixed shaft 205. The oil delivery channel 603 extends through to the top of the vertical guide rail 200 and communicates with the dripping assembly 700.

[0030] A sealing cylinder 604 is fixedly installed on the inner bottom wall of the base 100. An extension rod 602 is rotatably connected to the center of the sealing cylinder 604. A through hole 605 is opened on the circumferential surface of the bottom end of the extension rod 602. The oil delivery channel 603 communicates with the sealing cylinder 604 through the through hole 605. A piston oil delivery component is connected to the circumferential surface of the sealing cylinder 604. The piston oil delivery component is driven by the rotation of the rotating cylinder 601 to deliver lubricating oil into the sealing cylinder 604. After the lubricating oil enters the interior of the sealing cylinder 604, it passes through the through hole 605 and enters the oil delivery channel 603, and is finally delivered to the interior of the dripping assembly 700.

[0031] The piston oil delivery system includes piston cylinders 606 arrayed and fixed on the inner wall of the base 100. Two connecting pipes 607 are fixedly installed at the bottom of the piston cylinders 606. One connecting pipe 607 is connected at its bottom end to the side of the sealing cylinder 604, and the other connecting pipe 607 is located at its bottom end inside the base 100. Both connecting pipes 607 are equipped with one-way valves 608. Through the two one-way valves 608, lubricating oil inside the piston cylinder 606 can pass through one of the connecting pipes 607 into the sealing cylinder 604; lubricating oil inside the base 100 can pass through the other connecting pipe 607 into the piston cylinder 606.

[0032] A piston body 609 is slidably connected to the top of the piston cylinder 606. An arc-shaped plate 610 is fixedly installed on the top of the piston body 609. The arc-shaped plate 610 fits against the circumferential surface of the rotating cylinder 601. A sliding ball 611 is fixedly installed on the inner arc surface of the arc-shaped plate 610. V-shaped grooves 612 are arrayed on the circumferential surface of the rotating cylinder 601. The bottom of the V-shaped grooves 612 transitions into an arc shape. The tops of the V-shaped grooves 612 are connected by an arc-shaped groove 613. The center of the arc of the arc-shaped groove 613 coincides with the axis of the rotating cylinder 601. The sliding ball 611 is slidably connected within the V-shaped grooves 612 and the arc-shaped grooves 613. Thus, when the rotating cylinder 601 rotates, the sliding ball 611 slides along the V-shaped grooves 612 and the arc-shaped grooves 613, causing the piston body 609 to slide up and down reciprocally inside the piston cylinder 606.

[0033] The oil flow channel 603 is equipped with a flow-blocking component, which includes a transition cavity 614 opened in the fixed shaft 205. The transition cavity 614 is connected to the oil flow channel 603. A guide rod 615 is fixedly installed between the top wall and the bottom wall of the transition cavity 614. A sealing plug 616 is slidably connected to the guide rod 615. The sealing plug 616 is inserted into the bottom end of the transition cavity 614 where it connects to the oil flow channel 603. When the piston oil delivery component delivers lubricating oil into the oil delivery channel 603, the lubricating oil moves upward along the oil delivery channel 603, which can push the sealing plug 616 upward, so that the lubricating oil can flow upward through the gap between the sealing plug 616 and the side wall of the transition cavity 614; when the piston oil delivery component stops delivering lubricating oil into the oil delivery channel 603, the sealing plug 616 seals the connection between the bottom end of the transition cavity 614 and the oil delivery channel 603 under the action of gravity, preventing the lubricating oil inside the vertical guide rail 200 and the dripping assembly 700 from flowing downward along the oil delivery channel 603 under the action of gravity.

[0034] Please see Figure 11 The dripping assembly 700 includes an oil reservoir 701 fixedly installed at the top of the vertical guide rail 200. A holding groove 702 is fixedly installed at the center of the bottom wall of the oil reservoir 701, and the holding groove 702 communicates with the oil delivery channel 603. The piston oil delivery component delivers lubricating oil to the holding groove 702 through the oil delivery channel 603. As the amount of lubricating oil in the holding groove 702 increases, the lubricating oil overflows from the top of the holding groove 702 into the oil reservoir 701. Four protrusions 703 are fixedly installed at the bottom of the oil reservoir 701, and the protrusions 703 fit against the surface of the reinforcing edging 201. An oil leakage slit 704 is opened at the bottom end of the protrusions 703 facing the reinforcing edging 201. A dripping channel 705 is opened inside the oil reservoir 701 and the protrusions 703, and the oil leakage slit 704 communicates with the interior of the oil reservoir 701 through the dripping channel 705. The lubricating oil inside the oil reservoir 701 can drip through the drip channel 705 onto the surface of the reinforcing edging 201, thus lubricating the surface of the reinforcing edging 201. In practice, a filter cotton sheet can be inserted into the oil leakage gap 704 to reduce the downward flow speed of the lubricating oil.

[0035] An oil drain pipe 706 is fixedly installed at the bottom of the boss 703. A sliding sleeve 707 is fitted at the bottom end of the oil drain pipe 706. A valve stem 708 is fixedly installed at the center of the inner bottom wall of the sliding sleeve 707. The valve stem 708 is inserted into the oil drain pipe 706. The top of the valve stem 708 is in the shape of an inverted cone. A spring 709 is fixedly installed between the bottom end of the oil drain pipe 706 and the inner wall of the sliding sleeve 707. The spring 709 is used to drive the sliding sleeve 707 and the valve stem 708 to move downward and to make the valve stem 708 seal the bottom end of the oil drain pipe 706. A through hole 712 is opened at the bottom end of the sliding sleeve 707. When the output end of the hydraulic cylinder 303 extends, causing the upper slide block 302 to move upward to the top of the vertical guide rail 200, the roller 306 presses the sliding sleeve 707 upward. The sliding sleeve 707 and the valve stem 708 move upward, and the valve stem 708 no longer seals the bottom end of the oil drain pipe 706. The lubricating oil inside the holding tank 702 can pass through the guide pipe 711, the second drip channel 710, the oil drain pipe 706, and the second through hole 712 and drip onto the oil inlet of the roller 306, directly lubricating the roller 306 and the horizontal shaft 305.

[0036] Working principle: The hydraulic cylinder 303 retracts, reducing the distance between the upper slide block 302 and the lower slide block 301, and decreasing the angle between the upper rotating arm 401 and the support arm 406. This causes the covering shell 501 to move from right to left, bringing it closer to the drill string. Then, the motor 2 510 drives the bevel gear 509 to rotate. With the help of the transmission of bevel gear 3 507, bevel gear 4 508 and bevel gear 509, the inner shaft 503 and the sleeve 504 rotate in opposite directions, causing the jaw 1 505 and jaw 2 506 to deflect towards each other and clamp onto the drill string. Then, the hydraulic cylinder 303 extends at its output end, and the clamping assembly 500 clamps the drill string to the right. Then, the motor 211 drives the bevel gear 210 to rotate, which in turn drives the bevel gear 209, the turntable 202 and the vertical guide rail 200 to rotate. This causes the clamping assembly 500 to clamp the drill string and rotate around the vertical guide rail 200, thus transferring the drill string. After that, the motor 510 drives the bevel gear 509 to rotate in the opposite direction, and the jaws 505 and 506 release the drill string. When the vertical guide rail 200, turntable 202 and fixed shaft 205 rotate, the rotating drum 601 and extension rod 602 rotate synchronously. The sliding ball 611 slides along the V-groove 612 and arc groove 613, driving the piston body 609 to slide in the vertical direction. With the guidance of the connecting pipe 607 and one-way valve 608, the lubricating oil inside the base 100 is delivered to the sealing cylinder 604. After that, the lubricating oil passes through the through hole 605 and enters the oil delivery channel 603. The lubricating oil pushes the sealing plug 616 upward and flows upward through the gap between the sealing plug 616 and the side wall of the transition cavity 614. Then, the lubricating oil enters the holding tank 702 through the oil delivery channel 603 inside the vertical guide rail 200. As the lubricating oil in the holding tank 702 increases, the lubricating oil overflows from the top of the holding tank 702 into the oil storage box 701. Finally, the lubricating oil inside the oil storage box 701 drips onto the surface of the reinforcing edge 201 through the drip channel 705 to lubricate the reinforcing edge 201. When the upper slide block 302 slides along the vertical guide rail 200, the upper slide block 302 rolls on the reinforcing edge 201. The lubricating oil on the surface of the reinforcing edge 201 can pass through the oil inlet slit on the surface of the roller 306 to lubricate the roller 306 and the horizontal shaft 305. It can also extend through the output end of the hydraulic cylinder 303 to drive the upper slide block 302 to move upward, so that the roller 306 is pressed on the sliding sleeve 707. The sliding sleeve 707 and the valve stem 708 move upward, the spring 709 is compressed, and the valve stem 708 no longer seals the bottom end of the oil drain pipe 706. The lubricating oil inside the holding tank 702 can pass through the guide pipe 711, the second drip channel 710, the oil drain pipe 706, the sliding sleeve 707 and the second through hole 712 to drip onto the oil inlet slit of the support ring 206.
