[0040] This invention proposes an automatic drill rod feeding device and a pipe jacking machine, which aims to transport drill rods quickly and conveniently through a conveying pipe, a feeding assembly, and a tilting assembly. This greatly improves the automation level of the equipment, saves time, reduces the labor intensity of operators, and effectively improves the production efficiency of enterprises.

[0041] Please refer to Figures 1 to 8 The specific structure of the automatic drill rod feeding device 10 proposed in this invention will be described below in a specific embodiment. In one embodiment of this invention, the automatic drill rod feeding device 10 includes a conveying pipe 1, a feeding assembly 2, and a tilting assembly 3. The conveying pipe 1 has a conveying cavity 11 with an inlet 121 and an outlet 131. The feeding assembly 2 is located on one side of the outlet 131 and is used to intermittently convey the drill rod 4. The tilting assembly 3 is located on the side of the feeding assembly 2 away from the conveying pipe 1 and is movably pressed against the feeding assembly. The tilting assembly 3 is used to tilt and transport the drill rod 4. Thus, the drill rod 4 can be transported quickly and conveniently through the conveying pipe 1, the feeding assembly 2, and the tilting assembly 3, which greatly improves the automation level of the equipment, saves time, and reduces the labor intensity of the operators.

[0042] In this embodiment, the automatic drill rod feeding device 10 includes a conveying pipe 1, a feeding assembly 2, and a tilting assembly 3. The conveying pipe 1 has a conveying cavity 11 with an inlet 121 and an outlet 131. The conveying pipe 1 is used to convey the drill rod 4 to the feeding assembly 2, that is, the feeding assembly 2 is located on one side of the outlet 131. The tilting assembly 3 is located on the side of the feeding assembly 2 away from the conveying pipe 1, and the tilting assembly can move against the feeding assembly so that the feeding assembly can feed intermittently. Then, the drill rod 4, which passes through the conveying pipe, comes to the tilting assembly 3 through the feeding assembly 2, and is then transported to the required location by the tilting assembly 3, thereby realizing the transportation of the drill rod 4.

[0043] Specifically, the feeding assembly 2 is used to intermittently convey the drill rod 4, and under the pressure of the tilting assembly, the drill rod 4 passing through the feeding assembly can be intermittently conveyed, thereby enabling the tilting assembly to transport the drill rod 4 in a timely manner. The drill rod 4, entering the conveying pipe 1, is sequentially conveyed onto the tilting assembly 3 under the drive of the feeding assembly 2, thus achieving orderly conveying of the drill rod 4. Through the orderly cooperation between the feeding assembly 2 and the tilting assembly 3, the drill rod 4 can be quickly and conveniently transported to the required location.

[0044] It should be further explained that the conveying pipe 1 is L-shaped, that is, the conveying pipe 1 has two mutually perpendicular first ends 12 and second ends 13, and the first end 12 is located above the second end 13. At the same time, the feed inlet 121 is located on the first end 12 and the discharge outlet 131 is located on the second end 13. Then the drill rod 4 passes through the feed inlet 121, passes through the first end 12 and the second end 13 in sequence, and is then conveyed by the feeding assembly 2 and the tilting assembly 3.

[0045] Please refer to Figure 3 and Figure 4 In an optional embodiment, the conveying pipe 1 has a through-hole 14 in the wall of the conveying chamber near the discharge port;

[0046] The feeding assembly includes a base plate 21, a lifting member 22, and a driving member 23. The base plate 21 is installed at the bottom of the conveying pipe 1 and covers the through opening 14. The driving member 23 is located on one side of the base plate 21. The flipping member is movably pressed against the driving member 23. The driving member 23 is driven to connect to the lifting member 22 at the end away from the flipping member, so that the lifting member 22 can be movably inserted through the base plate 21 and can be movably extended and retracted in the through opening 14. The lifting member 22 is used to block or avoid the drill rod 4, so as to achieve the purpose of orderly conveying of the drill rod 4.

[0047] In this embodiment, the conveying pipe 1 has a through-hole 14 in the wall of the conveying chamber 11 near the discharge port 131. The base plate 21 is installed at the bottom of the conveying pipe 1 and covers the through-hole 14. The feeding assembly includes the base plate 21, the lifting plate and the driving member 23. The driving member 23 is disposed on one side of the base plate 21, and the flipping assembly moves against the driving member 23. The driving member 23 is driven to be connected to the lifting rod at the end away from the flipping assembly. When the flipping assembly moves against the driving member 23, the lifting rod extends and retracts within the base plate 21, thereby allowing the drill rod 4 or the blocking drill rod 4 to move towards the conveying assembly or to block subsequent drill rods 4 from moving towards the flipping assembly.

[0048] It should be noted that the substrate 21 is plate-shaped and is mounted on the bottom of the conveying pipe 1 by screws or the like.

[0049] Please refer to Figure 4 and Figure 5 In an optional embodiment, the driving component 23 further includes two oppositely arranged connecting rods 231 and a first connecting shaft 232. The first connecting shaft 232 is rotatably connected to one side of the substrate 21, and both ends of the first connecting shaft 232 are respectively connected to and pass through the middle position of the two connecting rods 231. The lifting component 22 is connected to the two connecting rods 231 at one end away from the substrate 21. The flipping component is movable against the connecting rods 231 so as to drive the lifting component 22 to block or avoid the drill rod 4 through the connecting rods 231.

[0050] In this embodiment, the driving component 23 further includes two opposing connecting rods 231 and a first connecting shaft 232. The first connecting shaft 232 is installed on the side of the substrate 21 away from the conveying pipe 1 and is rotatably connected to the substrate 21. Both ends of the first connecting shaft 232 are connected to and pass through the middle of the two connecting rods 231. It should be noted that the relationship between the first connecting shaft 232 and the two connecting rods 231 is a fixed connection. Meanwhile, the lifting component 22 is connected to the two connecting rods 231 at one end of the substrate 21, and the flipping assembly movably presses against the connecting rods 231, so that the lifting component 22 can be driven by the connecting rods 231 to block or avoid the drill rod 4.

[0051] It should be further explained that the substrate 21 is provided with two oppositely arranged mounting seats, and the two mounting seats are disposed between the two connecting rods 231. The first connecting shaft 232 passes through the two mounting seats in sequence, and the two ends of the first connecting shaft 232 are respectively connected to the two connecting rods 231, so that the connecting rods 231 can be mounted on the substrate 21. The first connecting shaft 232 is rotatably connected to the two mounting seats.

[0052] Please refer to Figures 4 to 6 In an optional embodiment, the driving member 23 further includes a linkage member 233, the two ends of which are respectively connected to the first connecting shaft 232 and pass through the two ends of the two connecting rods 231, and the linkage member 233 extends out of the substrate 21 at the end away from the first connecting shaft 232.

[0053] The flipping component can be movably pressed against one end of the linkage 233 extending out of the base plate 21, so that the linkage 233 drives the lifting component 22 to extend and retract on the base plate 21, thereby achieving the interception or avoidance of the drill rod 4.

[0054] In this embodiment, the driving component 23 further includes a linkage 233. The two ends of the linkage 233 are respectively connected to the first connecting shaft 232, which extends through the two ends of the two connecting rods 231. The linkage 233 extends out of the substrate 21 at the end away from the first connecting shaft 232. The flipping component presses against the end of the linkage 233 that extends out of the substrate 21, thereby driving the first connecting shaft 232 to rotate on the mounting base through the linkage 233. Since the relationship between the first connecting shaft 232 and the two connecting rods 231 is fixed, the first connecting shaft 232 rotates while driving the two connecting rods 231 to rotate, thereby driving the lifting component 22 to extend and retract within the substrate 21, thereby realizing the interception or avoidance of the drill rod 4 by the lifting rod.

[0055] It should be noted that the linkage 233 is U-shaped, meaning it has two opposing mounting feet 2331 and a connecting end 2332. The connecting end 2332 is connected to both mounting feet 2331. One mounting foot 2331 is connected to one end of the first connecting shaft 232, and the other mounting foot 2331 is connected to the other end of the second connecting shaft 234. The connecting end 2332 extends out of the base plate 21, allowing the flipping assembly to press against the connecting end 2332, thereby driving the first connecting shaft 232 and the two connecting rods 231 to rotate. Furthermore, the linkage 233 is a one-piece molded structure, ensuring structural strength and stability.

[0056] Please continue to refer to Figures 4 to 6 In an optional embodiment, the lifting member 22 includes a first lifting rod 221 and a second lifting rod 222. At least two first lifting rods 221 and at least two second lifting rods 222 are provided. At least two first lifting rods 221 and at least two second lifting rods 222 are respectively arranged at intervals on the base plate 21 in a conveying direction perpendicular to the drill rod 4.

[0057] At least one first lifting rod 221 and at least one second lifting rod 222 are connected at one end to one end of a connecting rod 231, and at least one other first lifting rod 221 and at least one other second lifting rod 222 are connected at one end to another connecting rod 231. By setting at least two first lifting rods 221 and at least two second lifting rods 222, the movement of the drill rod 4 can be effectively blocked, so that the drill rod 4 can be transported to the required location in an orderly manner through the flipping assembly.

[0058] In this embodiment, to facilitate effective interception of the drill rod 4, at least two first lifting rods 221 and two second lifting rods 222 are provided, for example, two, three, or more. At least two first lifting rods 221 and at least two second lifting rods 222 are spaced apart on the substrate 21 in a conveying direction perpendicular to the second end of the drill rod 4. On one hand, increasing the number of first lifting rods 221 and second lifting rods 222 increases the blocking stability of the drill rod 4. On the other hand, the spaced arrangement on the substrate 21 perpendicular to the conveying direction of the drill rod 4 ensures effective interception of the drill rod 4. Of course, the number of first lifting rods 221 and second lifting rods 222 should not be excessive. Here, two first lifting rods 221 and two second lifting rods 222 are provided, and the two first lifting rods 221 and two second lifting rods 222 are spaced apart on the substrate 21 in a conveying direction perpendicular to the drill rod 4, thereby effectively blocking the drill rod 4 and ensuring subsequent transport stability.

[0059] Specifically, at least one end of the first lifting rod 221 and the second lifting rod 222 is connected to one end of the connecting rod 231, and at least one end of the other first lifting rod 221 and at least one other second lifting rod 222 is connected to one end of the other connecting rod 231. A first connecting shaft 232 is positioned between the first lifting rod 221 and the second lifting rod 222, and is connected to the middle of the connecting rod 231. In the non-operating state, when the flipping assembly is flipped to a certain angle, it does not press against the linkage 233. At this time, the second lifting rod 222 extends out of the substrate 21, while the first lifting rod 221 retracts into the substrate 21. Thus, the drill rod 4 can smoothly enter the substrate 21 from the delivery pipe 1 and be blocked by the second lifting rod 222. The flipping assembly flips back to the side of the discharge port. At this time, the linkage 233 is pressed by the flipping assembly, which in turn drives at least two first lifting rods 221 to extend out of the substrate 21, and the second lifting rod 222 retracts into the substrate 21. At this time, the drill rod 4 that enters the substrate 21 enters the flipping assembly and is transported by the flipping assembly. The subsequent drill rod 4 is blocked by at least two first lifting rods 221 so that the subsequent drill rod 4 cannot pass through the substrate 21 to reach the flipping assembly.

[0060] Please continue to refer to Figure 4 and Figure 5 In an optional embodiment, the feeding assembly further includes a second connecting shaft 234 and a third connecting shaft 235. Both ends of the second connecting shaft 234 and the third connecting shaft 235 are connected to both ends of the two connecting rods 231. One end of at least two first lifting rods 221 is connected to the second connecting shaft 234, and one end of at least two second lifting rods 222 is connected to the third connecting shaft 235. Through the second connecting shaft 234 and the third connecting shaft 235, the first lifting rods 221 and the second lifting rods 222 can be stably connected to the connecting rods 231.

[0061] In this embodiment, the feeding assembly further includes a second connecting shaft 234 and a third connecting shaft 235. The two ends of the second connecting shaft 234 are respectively connected to one end of each of the two connecting rods 231, while the third connecting shaft 235 is respectively connected to the other end of each of the two connecting rods 231. That is, the first connecting shaft 232, the second connecting shaft 234, and the third connecting shaft 235 are arranged parallel to each other and are respectively connected to the two connecting rods 231, with the first connecting shaft 232 positioned between the second connecting shaft 234 and the third connecting shaft 235. It should be noted that the connection between the second connecting shaft 234, the third connecting shaft 235, and the two connecting rods 231 is a fixed connection. When the linkage 233 is pressed against the flipping assembly, the linkage 233 drives the first connecting shaft 232 to rotate within the mounting base. Since the connection between the first connecting shaft 232 and the two connecting rods 231 is fixed, the linkage 233 drives the two connecting rods 231 to rotate, thereby driving the second connecting shaft 234 and the third connecting shaft 235 connected to both ends of the two connecting rods 231, thus enabling the first lifting rod 221 to extend or retract, or the second lifting rod 222 to extend or retract. When the flipping assembly presses against the linkage 233, the first lifting rod 221 extends and the second lifting rod 222 retracts. The first lifting rod 221 serves to prevent the drill rod 4 from entering the flipping assembly through the base plate 21. When the flipping assembly drives the drill rod 4 to flip, the flipping assembly no longer presses against the linkage 233, and the second lifting rod 222 extends out of the substrate 21. At this time, the first lifting rod 221 retracts into the substrate 21, and the drill rod 4 enters into the substrate 21 and is blocked by the second lifting rod 222.

[0062] Please refer to Figures 4 to 6 In an optional embodiment, the feeding assembly further includes at least two elastic members 24, one end of each elastic member 24 is connected to each second lifting rod 222, and the other end of each elastic member 24 is connected to the substrate 21. By setting the elastic members 24, the second lifting rod 222 can always extend out of the substrate 21 without the action of external force, while the first lifting rod 221 is always retracted into the substrate 21, so that the drill rod 4 can smoothly enter the substrate 21.

[0063] In this embodiment, the feeding assembly further includes at least two elastic elements 24, with one end of each elastic element 24 connected to each second lifting rod 222, and the other end of each first elastic element 24 abutting against the substrate 21. Under the rebound action of the elastic elements 24, the second lifting rod 222 can always extend out of the substrate 21 without external force, while the first lifting rod 221 is always retracted into the substrate 21, thus allowing the drill rod 4 to smoothly enter the substrate 21. When the flipping assembly is not pressing against the linkage 233, the second lifting rod 222 extends out of the substrate 21 under the rebound action of the elastic elements 24. At this time, the first lifting rod 221 retracts into the substrate 21 under the drive of the connecting rod 231, and the drill rod 4 enters the substrate 21 and is intercepted by the second lifting rod 222. It should be noted that the elastic element 24 is a spring or the like.

[0064] It is understood that the substrate 21 has through holes 211 for the extension and retraction of the first lifting rod 221 and the second lifting rod 222, and the number of through holes 211 corresponds to the number of the first lifting rod 221 and the second lifting rod 222. That is, one end of the elastic member 24 abuts against the bottom wall of the through hole 211, and the other end abuts against the end face of the second lifting rod 222.

[0065] Furthermore, to prevent wear between the first lifting rod 221 and the second lifting rod 222 and the substrate 21, the feeding assembly also includes at least four linear bearings 25, and each linear bearing 25 is installed in each through hole 211. Each first lifting rod 221 and each second lifting rod 222 passes through the inner peripheral wall of the linear bearing 25 to prevent direct contact between the first lifting rod 221, the second lifting rod 222 and the hole wall of the through hole 211. Since the linear bearing 25 is provided with balls, the friction and wear of the first lifting rod 221 and the second lifting rod 222 are further reduced.

[0066] Please refer to Figure 7 In an optional embodiment, the flipping assembly 3 includes a drive motor 31 and a flipping component 32. The drive motor 31 is connected to one end of the flipping component 32, and the other end of the flipping component 32 abuts against one side of the discharge port 131. The drill rod falls into the flipping component 32, and then the drive motor 31 drives the flipping component 32 to flip, thereby driving the drill rod to flip.

[0067] In this embodiment, the flipping assembly 3 includes a drive motor 31 and a flipping component 32. The drive motor 31 is connected to the flipping component 32, and the other end of the flipping component 32 abuts against one side of the discharge port 131. The drill rod enters the flipping component 32 through the feeding assembly 2, and under the drive of the drive motor 31, the drill rod is transported to the required location.

[0068] To further explain, the flipping component 32, driven by the drive motor 31, can movably press against the linkage component 233.

[0069] Please continue to refer to Figure 7 In an optional embodiment, the flipping member 32 includes two oppositely arranged flipping arms 321. One end of each flipping arm 321 is connected to the output shaft of the drive motor 31, and the other end of each flipping arm 321 is provided with a placement groove 3211 for the drill rod to fall into. By providing a placement groove 3211 on the flipping arm 321, the drill rod can be stably placed on the flipping member 32.

[0070] In this embodiment, in order to facilitate the stable entry of the drill rod into the flipping member 32, the flipping member 32 includes two opposing flipping arms 321, and each flipping arm 321 has a placement groove 3211 on one end near the discharge port 131. When the drill rod enters the flipping member 32, the drill rod falls into the placement groove 3211, and under the drive of the drive motor 31, the flipping arm 321 is flipped, so that the drill rod falling into the placement groove 3211 can be stably transported.

[0071] Specifically, the flipping component 32 also includes two pressure blocks 34. Each pressure block 34 is installed on one side of each flipping arm 321 away from the placement groove 3211. When the flipping arm 321 flips to face the discharge port 131, the pressure block 34 on each flipping arm 321 presses against the linkage 233, thereby enabling the linkage 233 to drive the connecting rod 231 to rotate.

[0072] Furthermore, in order to improve the stability of the drill rod in the placement groove 3211, the flipping assembly 3 also includes two opposing clamping members 33. Each clamping member 33 is installed on one side of each flipping arm 321, and each clamping member 33 is arranged close to the side wall of the placement groove 3211 away from the discharge port 131. Each clamping member 33 is used to clamp the drill rod in the placement groove 3211. Thus, the drill rod that falls into the placement groove 3211 can be stably fixed in the placement groove 3211 under the clamping action of the clamping member 33, thereby effectively preventing the drill rod from falling out of the placement groove 3211, and also effectively preventing the drill rod from falling out of the placement groove 3211 during the flipping process.

[0073] Specifically, each clamping component 33 includes a movable block 331, a fixed block 332, and a spring 333. The fixed block 332 is mounted on the tilting arm 321. One end of the spring 333 is connected to the movable block 331, and the other end of the spring 333 is connected to the fixed block 332. The movable block 331 is set towards the placement groove 3211. Thus, once the drill rod enters the placement groove 3211, the movable block 331 can clamp the drill rod in the placement groove 3211 under the rebound force of the spring 333.

[0074] The present invention further proposes a pipe jacking machine, which includes an automatic drill rod feeding device 10 as described in any of the above embodiments. Since the specific structure of the automatic drill rod feeding device 10 in this pipe jacking machine refers to the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0075] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
