Description

Technical Field

[0001] This utility model relates to the technical field of pipe handling devices, specifically to a pipe picking device. Background Technology

[0002] While handling devices equipped with multi-degree-of-freedom robotic arm systems are highly flexible and can adapt to various grasping and handling scenarios during pipeline movement for construction operations, their cost and maintenance are considerable, making them unsuitable for low-cost pipeline operation scenarios.

[0003] Currently, in low-cost pipeline operation scenarios, manual handling of pipelines is often used, which is slow and unsafe. Furthermore, when stacked pipelines are removed one by one by hand, they are prone to slipping and other phenomena, making them inconvenient to handle and highly dangerous.

[0004] Therefore, there is an urgent need for a pipe retrieval device to solve the problem of the inconvenience of manually removing pipes one by one from a pile of pipes. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a pipe retrieval device to solve the problem of the inconvenience of manually removing pipes one by one from a stack of pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pipe-handling device includes two eccentric wheel supports symmetrically arranged, with pipe grooves symmetrically formed on opposite sides of each support. The upper ends of the pipe grooves are open, allowing for the placement of both ends of a pipe assembly. Each eccentric wheel support also has an inverted "L"-shaped moving groove, with an open front end and a retaining slope at the upper corner. The lower end of the pipe groove is connected to the retaining slope of the moving groove. Either eccentric wheel support... The side wall of the wheel support is also rotatably provided with a non-powered eccentric wheel. The side of the non-powered eccentric wheel is provided with a concave groove arc surface. The two sides of the groove arc surface are a large convex arc with a larger radius and a small convex arc with a smaller radius. The non-powered eccentric wheel can rotate to the side of the small convex arc where the pipe groove and the moving groove are connected due to its own weight, or the groove arc surface can support a single pipe falling on the retention slope, or rotate to the side of the large convex arc where the pipe groove and the moving groove are connected, and the pipe can detach from the groove arc surface and slide out of the moving groove.

[0008] To optimize the above technical solution, the specific measures also include:

[0009] Furthermore, the lower end face of the pipe groove is set as a slope surface with a height that gradually decreases from back to front, and the front end of the slope surface is connected to the movable groove.

[0010] Furthermore, the connection between the pipe channel and the moving channel is only open to a single pipe.

[0011] Furthermore, the unpowered eccentric wheel is rotatably mounted on the eccentric wheel support via a pin.

[0012] Furthermore, it also includes a rotating pusher device, which is disposed between the two eccentric wheel supports and is used to push the pipe, which is supported by the groove arc surface of the unpowered eccentric wheel and falls on the retention slope, toward the front opening of the moving groove.

[0013] Furthermore, the rotary push tube device includes a stepper motor, a rotary short handle, a connecting long handle, a push rod, and a push tube base. The push tube base is disposed between the two eccentric wheel supports, and a sliding elongated groove in the front-back direction is provided on the push tube base. The stepper motor is mounted on the push tube base, and the output shaft of the stepper motor rotatably passes through the push tube base and is connected to one end of the rotary short handle. The other end of the rotary short handle is hinged to one end of the long handle. The other end of the connecting long handle is fixedly connected to one end of the push rod, and the connection between the push rod and the connecting long handle is slidably connected in the sliding elongated groove through a sliding shaft. The other end of the push rod is used to push the pipe, and the stepper motor is used to drive the rotary short handle to rotate and drive one end of the push rod to slide along the sliding elongated groove.

[0014] Furthermore, the push rod is provided with a push gripper at the end of the pipe used to push the pipe.

[0015] Furthermore, the push tube base is provided with a shaft hole through which the output shaft of the stepper motor can rotatably pass.

[0016] The beneficial effects of this utility model are:

[0017] In use, this utility model device allows for the placement of pipes at both ends of a pipe group via pipe grooves on two eccentric wheel supports, thus achieving stable placement of the pipe group. Simultaneously, as shown in the attached diagram, when there are no pipes in the pipe grooves of the eccentric wheel supports, the small convex arc of the unpowered eccentric wheel rotates under gravity to the side of the connection between the pipe groove and the moving groove, blocking the outlet of the pipe groove. As shown in the attached diagram, when there are several pipes in the pipe groove, the unpowered eccentric wheel can be rotated under gravity or manually, causing each pipe in the pipe groove to fall one by one into the grooved arc surface of the unpowered eccentric wheel, and then into the moving groove, landing on the retention slope. Then, as shown in the attached diagram, the unpowered eccentric wheel continues to rotate under gravity or manually, causing the pipes in the grooved arc surface to slide out along the moving groove. At this point, the large convex arc can block the outlet of the pipe groove. Therefore, it is possible to conveniently stack pipe groups and remove pipes one by one as needed, solving the problem of the inconvenience of manually removing pipes one by one from a stacked pile.

[0018] The rotating pusher device of this utility model can make the pipe fall into the groove arc surface of the unpowered eccentric wheel along the pipe groove, and fall on the retention slope after entering the moving groove. When the pipe cannot continue to slide out from the retention slope on its own, the rotating pusher device can push it to complete the subsequent movement, so there is no need to manually drive the unpowered eccentric wheel.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] As attached Figure 1 Appendix Figure 3 and attached Figure 5 As shown, a pipe-handling device according to an embodiment of the present invention includes two eccentric wheel supports 2, which are symmetrically arranged. Pipe grooves 9 are symmetrically formed on opposite sides of the two eccentric wheel supports 2. The upper end of each pipe groove 9 is open, and the two pipe grooves 9 on both sides can accommodate the two ends of a pipe group 8. An inverted "L"-shaped moving groove is also formed on each of the two eccentric wheel supports 2. The front end of the inverted "L"-shaped moving groove is open, and a retaining slope 5 is formed at the corner of the upper end of the moving groove. The lower end of the pipe groove 9 is connected to the retaining slope 5 of the moving groove. Either eccentric wheel support... The side wall of 2 is also provided with a non-powered eccentric wheel 1. The side of the non-powered eccentric wheel 1 is provided with a concave groove arc surface 11. The two sides of the groove arc surface 11 are a large convex arc 13 with a larger radius and a small convex arc 12 with a smaller radius. The non-powered eccentric wheel 1 can rotate to the side of the small convex arc 12 where the pipe groove 9 is connected to the moving groove due to its own weight, or the groove arc surface 11 can support a single pipe 6 that falls on the retention slope 5, or rotate to the side of the large convex arc 13 where the pipe groove 9 is connected to the moving groove, and the pipe 6 can detach from the groove arc surface 11 and slide out of the moving groove.

[0035] In use, this utility model device allows for the placement of both ends of the pipe 6 in the pipe group 8 via the pipe grooves 9 of the two eccentric wheel supports 2, thereby achieving stable placement of the pipe group 8. Additionally, as shown in the attached... Figure 2 As shown, when there is no pipe 6 in the pipe groove 9 of the eccentric wheel support 2, the small convex arc 12 of the unpowered eccentric wheel 1 will rotate to the side of the connection between the pipe groove 9 and the moving groove under the action of gravity, and block the outlet of the pipe groove 9; as shown in the attached figure Figure 6As shown, when there are several pipes 6 in the pipe groove 9, the unpowered eccentric wheel 1 can be rotated under the action of gravity or manually, causing the several pipes 6 in the pipe groove 9 to fall one by one into the groove arc surface 11 of the unpowered eccentric wheel 1 along the pipe groove 9, and then fall onto the retention slope 5 after entering the moving groove. After that, as shown in the attached figure... Figure 7 As shown, under the action of gravity or by manual driving, the unpowered eccentric wheel 1 continues to rotate, causing the pipe 6 in the groove arc surface 11 to slide out along the moving groove. At this time, the large convex arc 13 can block the outlet of the pipe groove 9. In this way, the pipe group 8 can be stacked conveniently, and the pipe 6 can be taken out one by one as needed, solving the problem of the inconvenience of manually taking out the pipe 6 one by one from the stacked pipes.

[0036] In the above scheme, the setting of the retention slope 5 can buffer the pipe 6 after it falls into the arc surface 11 of the groove, and prevent several pipes 6 from continuously sliding out automatically under their own gravity.

[0037] As attached Figure 4 As shown, the outer structure of the unpowered eccentric wheel 1 in the above scheme can be composed of four circular arcs with radii of diameters R1, R2, R3 and R4 respectively.

[0038] The lower end face of the pipe groove 9 is designed as a ramp 10 with its height gradually decreasing from back to front, and the front end of the ramp 10 is connected to the moving groove. This facilitates the guidance of the movement of the pipe 6 via the ramp 10.

[0039] The connection between the pipe groove 9 and the moving groove is only open to a single pipe 6.

[0040] Among them, the unpowered eccentric wheel 1 is rotatably mounted on the eccentric wheel support 2 via the pin 20.

[0041] In another specific embodiment based on the above, a rotary pusher device 4 is also included. The rotary pusher device 4 is disposed between two eccentric wheel supports 2 and is used to push the pipe 6, which is supported by the grooved arc surface 11 of the unpowered eccentric wheel 1 and falls on the retention slope 5, towards the front opening of the moving groove. Thus, in use, when the pipe 6 falls into the grooved arc surface 11 of the unpowered eccentric wheel 1 along the pipe groove 9 and falls on the retention slope 5 after entering the moving groove, and the pipe 6 cannot actively continue to slide out from the retention slope 5, the rotary pusher device 4 can push it to complete the subsequent movement, so there is no need to manually drive the unpowered eccentric wheel 1.

[0042] As attached Figure 8 and attached Figure 9As shown, the rotary push tube device 4 includes a stepper motor 3, a rotary short handle 15, a connecting long handle 16, a push rod 17, and a push tube base 14. The push tube base 14 is located between two eccentric wheel supports 2, and a sliding elongated groove 19 in the front-back direction is provided on the push tube base 14. The stepper motor 3 is mounted on the push tube base 14, and the output shaft of the stepper motor 3 rotatably passes through the push tube base 14 and is connected to one end of the rotary short handle 15. The other end of the rotary short handle 15 is hinged to one end of the long handle 16. The other end of the long handle 16 is fixedly connected to one end of the push rod 17, and the connection between the push rod 17 and the connecting long handle 16 is slidably connected in the sliding elongated groove 19 through a sliding shaft 18. The other end of the push rod 17 is used to push the pipe 6, and the stepper motor 3 is used to drive the rotary short handle 15 to rotate and drive one end of the push rod 17 to slide along the sliding elongated groove 19.

[0043] Therefore, when using it, as shown in the attached document Figure 11 As shown, the stepper motor 3 rotates at a preset angle, causing the short rotating handle 15 to start rotating clockwise. The short rotating handle 15 drives the connecting long handle 16 to rotate, while the sliding shaft 18 slides in the sliding elongated groove 19, causing the push rod 17 to approach the pipe 6 located on the retention slope 5, and as shown in the attached figure. Figure 12 As shown, push rod 17 pushes pipe 6 to gradually disengage from the grooved arc surface 11 of the unpowered eccentric wheel 1, and then... (See attached image) Figure 13 As shown, push rod 17 pushes pipe 6 to separate from unpowered eccentric wheel 1 and slides out of the moving slot to complete the retrieval.

[0044] When push rod 17 pushes pipe 6 to move gradually according to the unpowered eccentric wheel 1, the unpowered eccentric wheel 1 will rotate synchronously, so that the large convex arc 13 of the unpowered eccentric wheel 1 will block several pipes 6 in the pipe groove 9. When push rod 17 pushes pipe 6 away from the groove arc surface 11 of the unpowered eccentric wheel 1, the unpowered eccentric wheel 1 loses its constraint, returns according to its own weight, and receives the next pipe 6 into the groove arc surface 11.

[0045] The push rod 17 is used to push the end of the pipe 6, which is equipped with a push grip. This facilitates the connection of the pipe 6.

[0046] As attached Figure 10 As shown, the push tube base 14 has a shaft hole 7 through which the output shaft of the stepper motor 3 can rotatably pass.

[0047] The components of this utility model are symmetrically distributed, and the forces are balanced on both sides. The entire mechanism is simple in principle, low in cost, and easy to operate. It only requires setting the operating parameters of the stepper motor 3 in advance, setting the lengths of the rotating short handle 15, the connecting long handle 16, and the push rod 17, as well as the angle between the connecting long handle 16 and the push rod 17, to ensure the movement trajectory of the push rod 17 to push the end of the pipe 6. After that, the pipe 6 can be moved and used as soon as the machine is turned on, which is extremely convenient.
