[0002] In the production process of pipes, a traction machine is needed to transfer the pipes between different processing devices in the processing system.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0029] Embodiment 1:

[0030] A pipe pulling device, such as Figure 1 As shown, it includes a base plate 1, a pipe clamping part, a guide rail 3 and a driving mechanism. At least one pipe clamping part is installed on the base plate 1. The base plate 1 is slidably installed on the guide rail 3. Limit baffles 31 are respectively provided at both ends of the length direction of the guide rail 3. The limit baffles 31 can prevent the base plate 1 from sliding off the guide rail 3. An anti-collision layer can also be provided on the limit baffle 31. When the base plate 1 slides to the two ends of the guide rail 3 and stops, the anti-collision layer can avoid damage to the base plate 1 and the pipe due to impact force.

[0031] A sliding member 11 is provided at the bottom of the base plate 1. Under the action of the driving mechanism, the sliding member 11 slides along the guide rail 3 and drives the base plate 1 to slide along the guide rail 3.

[0032] The length of the guide rail 3 can be set according to actual needs, and multiple sections of the guide rail 3 connected together can also be used to flexibly adjust the length of the guide rail 3.

[0033] In this embodiment, there are two driving mechanisms, which are respectively installed at both ends of the guide rail 3 in the length direction. The driving mechanism includes a traction rope 43, a traction wheel 42 and a driving motor 41. One end of the traction rope 43 is connected to the base plate 1, and the other end of the traction rope 43 is wound around the traction wheel 42. The traction wheel 42 is connected to the driving motor 41 and rotates when the driving motor 41 is working.

[0034] In other embodiments, the number of driving mechanisms can be increased as needed. For example, when the base plate 1 is long or the mass of the pipe is large, two driving mechanisms are respectively provided at both ends of the guide rail 3 to ensure the sliding speed of the base plate 1 on the guide rail 3.

[0035] Driving mechanisms are respectively provided at both ends of the guide rail 3 in the length direction, and the two driving mechanisms work in turn to move the base plate 1 back and forth on the guide rail 3 .

[0036] In this embodiment, a pipe cutting machine is provided at one end of the guide rail 3 to continuously cut the pipe, and the other end of the guide rail 3 is provided at a pipe processing device to perform the next step of processing on the pipe.

[0037] The specific working process is as follows: the pipe clamping part on the bottom plate 1 fixes the multiple pipes cut by the pipe cutting machine on the bottom plate 1, and the driving motor 41 at one end of the pipe processing equipment works to drive the traction wheel 42 to rotate. One end of the traction rope 43 is wound around the traction wheel 42, and the other end is connected to the bottom plate 1. The traction wheel 42 rotates so that the traction rope 43 is continuously wound around the traction wheel 42, thereby driving the bottom plate 1 to move toward one end of the pipe processing equipment. When the bottom plate 1 moves to one end of the pipe processing equipment, the driving motor 41 stops working and the bottom plate 1 is moved to one end of the pipe processing equipment. The pipe clamped by the pipe clamping part on the plate 1 is unloaded; the driving motor 41 at one end of the pipe cutting machine works to drive the traction wheel 42 to rotate, one end of the traction rope 43 is wound around the traction wheel 42, and the other end is connected to the bottom plate 1. The traction wheel 42 rotates so that the traction rope 43 is continuously wound around the traction wheel 42, thereby driving the bottom plate 1 to move toward one end of the pipe cutting machine. When the bottom plate 1 moves to one end of the pipe cutting machine, the multiple pipes cut by the pipe cutting machine are fixed on the bottom plate 1 through the pipe clamping part on the bottom plate 1, and the above steps are repeated.

[0038] In actual use, the length of the traction rope 43 can also be limited to be equal to the length of the guide rail 3. In this way, when the base plate 1 moves to one end of the guide rail 3, the traction rope 43 is also the longest, cooperating with the limit baffle 31 to further prevent the base plate 1 and the pipe from being damaged due to impact force.

[0039] In this embodiment, the pipe clamping portion includes a first fixed plate 21, a first movable plate 22, a second movable plate 23 and a second fixed plate 24 which are sequentially mounted on the base plate 1; the first fixed plate 21 and the second fixed plate 24 are fixedly mounted on the base plate 1, and clamping blocks 25 for clamping the pipe are respectively mounted on the relative inner sides of the first fixed plate 21 and the first movable plate 22, and clamping blocks 25 for clamping the pipe are respectively mounted on the relative inner sides of the second movable plate 23 and the second fixed plate 24; the first movable plate 22 and the second movable plate 23 are slidably mounted on the base plate 1 and are connected by a reset spring 26, and electromagnets 27 are respectively mounted on the relative inner sides of the first movable plate 22 and the second movable plate 23, and the magnetism of the electromagnet 27 of the first movable plate 22 and the electromagnet 27 of the second movable plate 23 are opposite after power is supplied.

[0040] When in use, first energize the electromagnet 27, the first movable plate 22 and the second movable plate 23 approach each other, the interval between the first fixed plate 21 and the first movable plate 22 increases, the interval between the second movable plate 23 and the second fixed plate 24 increases, the pipe is placed in the two intervals, or the pipe is moved out of the interval, the electromagnet 27 is powered off, and under the elastic force of the return spring 26, the first movable plate 22 moves toward the first fixed plate 21 to fix the pipe, and the second movable plate 23 moves toward the second fixed plate 24 to fix the pipe.

[0041] In this embodiment, the pipe clamping part is suitable for pipes of different specifications, and the electromagnets 27 of multiple pipe clamping parts can be connected through a controller, and the electromagnets 27 of multiple pipe clamping parts can be powered on or off in batches. Multiple pipes can be fixed on the base plate 1 at the same time, or released from the base plate 1, which has a higher degree of automation and saves time and labor costs.

[0042] The clamping surface of the clamping block 25 is arc-shaped, and a buffer layer is provided on the clamping surface. A plurality of buffer blocks are evenly distributed on the buffer layer. The buffer blocks are elastic rubber blocks. A buffer layer is provided on the clamping surface of the clamping block 25, and the buffer layer is provided with buffer blocks, which can prevent the clamping block 25 from damaging the pipe by applying excessive force.

[0043] A slide groove is provided on the bottom plate 1, and the first movable plate 22 and the second movable plate 23 are slidably installed in the slide groove and slide back and forth between the first fixed plate 21 and the second fixed plate 24 along the slide groove. The slide groove is a dovetail groove or a T-shaped groove.

[0044] The number of the guide rails 3 is at least one, and the guide rails 3 are evenly distributed below the bottom plate 1 . The number of the sliding members 11 is the same as the number of the guide rails 3 , and each of the sliding members 11 is disposed in one of the guide rails 3 .

[0045] Since multiple pipes are clamped at the same time, the bottom plate 1 is relatively long, and multiple guide rails 3 can be set at the bottom of the bottom plate 1, which not only makes the load-bearing uniform and increases the reliability of the device, but also makes the movement of the bottom plate 1 more convenient.

[0046] In this embodiment, the sliding member 11 is a roller with low friction, which can make the bottom plate 1 slide more easily on the guide rail 3. In other embodiments, the sliding member 11 can be a slider, and the size of each slider is matched with the size of the guide rail 3 where the slider is located.

[0047] Each guide rail 3 is also provided with a limiting mechanism that cooperates with the sliding member 11. The bottom plate 1 can be fixed on the guide rail 3 through the limiting mechanism so as to perform various operations. In some cases, the bottom plate 1 needs to be fixed in the middle of the guide rail 3, and the position of the bottom plate 1 can be fixed by the limiting mechanism. The limiting mechanism cooperates with the sliding member, and can be a limiting block, a baffle, or other commonly used limiting methods.

[0048] The driving structure includes a bracket 44, a connecting shaft 45, a driving motor 41, at least one traction wheel 42, and at least one traction rope 43. The number of traction wheels 42 is not less than the number of traction ropes 43.

[0049] The driving motor 41 is connected to the connecting shaft 45, and the connecting shaft 45 is installed on the bracket 44. The connecting shaft 45 rotates when the driving motor 41 works; all the traction wheels 42 are sleeved on the connecting shaft 45, and the traction wheels 42 rotate when the connecting shaft 45 rotates; one end of each traction rope 43 is respectively connected to different positions of the base plate 1, and the other end of each traction rope 43 is respectively wound around a traction wheel 42.

[0050] The base plate 1 is provided with a plurality of buckles 12 at different positions, and each traction rope 43 is connected to the base plate 1 via the buckle 12 , so that it is convenient to replace the traction rope 43 of different lengths or to install the traction rope 43 at different positions of the base plate 1 .

[0051] A plurality of traction ropes 43 are connected to the bottom plate 1 , which can make the bottom plate 1 bear force more evenly and slide more stably when the bottom plate 1 is relatively long.

[0052] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
