Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] This embodiment provides a steel pipe transfer device. Refer to Figures 1 to 3 As shown in the figure, it includes a frame 100, and also includes a driving device 200, a power shaft 300 and a plurality of material supporting arms 400 provided on the frame 100.

[0023] Among them, the power shaft 300 can be driven by the driving device 200 to rotate. The material supporting arms 400 are arranged at intervals along the axial direction of the power shaft 300. Each material supporting arm 400 respectively includes a box body 410, two material supporting pieces 430 and a central gear 420. The box body 410 is in a long strip shape, and the middle part of the box body 410 is fixedly sleeved on the power shaft 300. The two material supporting pieces 430 are respectively rotatably arranged on the box body 410 and are disposed on two opposite sides of the power shaft 300. The two material supporting pieces 430 are respectively provided with material supporting grooves 401.

[0024] The central gear 420 is located inside the box body 410 and is coaxial with the power shaft 300, and has a fixing part 421 fixedly connected to the frame 100. The two material supporting pieces 430 are respectively coaxially and fixedly provided with first gears 431, and a plurality of transmission gears 432 are respectively arranged between the two first gears 431 and the central gear 420. When the power shaft 300 drives the box body 410 to rotate, with the driving of the central gear 420 on the first gear 431, the material supporting groove 401 keeps facing upward.

[0025] That is, in the steel pipe transfer device of this embodiment, by setting the above-mentioned mechanism, the driving device 200 can drive the power shaft 300 to rotate. The rotation of the power shaft 300 will drive the box body 410 to rotate. When the box body 410 rotates, it will drive the transmission gears 432 meshing with the central gear 420 to revolve around the central gear 420, so that each central gear 420 and the first gear 431 rotate.

[0026] Through the self-rotation of the first gear 431, the brackets 401 on the two supporting members 430 can remain facing upward when the two supporting members 430 rotate with the box body 410; thereby, the two brackets 401 can alternately lift the steel pipe on one side and put it down on the other side, for example, lift the steel pipe on a frame with a single steel pipe and place it on a conveying mechanism.

[0027] refer to Figure 2 and Figure 4 As shown, in this embodiment, a connecting member 411 is provided on the box body 410, and the connecting member 411 has a sleeve portion mounted on the power shaft 300, and a first locking member 440 is provided on the sleeve portion. The first locking member 440 can be connected to or disconnected from the power shaft 300, and when the first locking member 440 is connected to the power shaft 300, the power shaft 300 can drive the sleeve portion to rotate.

[0028] Specifically, when the first locking member 440 is connected to the power shaft 300, the rotation of the power shaft 300 will drive the box 410 to rotate through the connecting member 411; and when the first locking member 440 is detached from the power shaft 300, the rotation of the power shaft 300 will not drive the box 410 to rotate.

[0029] In this embodiment, by setting the above-mentioned connecting member 411 and the first locking member 440, the support arm 400 can be selectively operated, so that the steel pipe transfer device can be better adapted to steel pipes of different lengths. Specifically, when the steel pipe is longer, more support arms 400 can be rotated with the power shaft 300 to better support the steel pipe; and when the steel pipe is shorter, fewer support arms 400 can be rotated with the power shaft 300 to reduce the load of the drive device 200.

[0030] In this embodiment, a plurality of threaded holes are evenly and spaced apart on the outer circumference of the sleeve portion along the circumference of the sleeve portion; the first locking member 440 is a top screw that is screwed to each threaded hole in a one-to-one correspondence.

[0031] Based on the above structure, when the top screw rotates to abut against the power shaft 300, the power shaft 300 can drive the box 410 to rotate, and when the top screw rotates to be separated from the power shaft 300, the power shaft 300 will not be able to drive the box 410 to rotate.

[0032] In some embodiments, multiple pin holes can also be set on the power shaft 300, and through holes corresponding to each pin hole can be set on the sleeve part. The first locking member 440 corresponds to the pin shaft. When the pin shaft passes through the through hole and is inserted into the corresponding pin hole, the power shaft 300 can drive the box body 410 to rotate, and when the pin shaft escapes from the pin hole, the power shaft 300 cannot drive the box body 410 to rotate.

[0033] refer to Figure 1As shown, the driving device 200 of this embodiment is a double-output shaft motor provided on the frame 100; the power shafts 300 are two groups respectively connected to the motor shafts on both sides of the double-output shaft motor.

[0034] In this embodiment, referring to Figure 1 and Figure 2 As shown, corresponding to each material supporting arm 400, brackets are provided on the frame 100 and located on two opposite sides of the material supporting arm 400 respectively. A first through hole is provided on one of the two brackets, which is hereinafter referred to as the first bracket 510 in the following description of this embodiment. A bearing is installed in the first through hole, and the power shaft 300 passes through the bearing so that the power shaft 300 can rotate.

[0035] A second through hole is provided on the other of the two brackets, which is hereinafter referred to as the second bracket 520 in the following description of this embodiment. The fixing part 421 of the aforementioned central gear 420 is a cylinder coaxially and press-fitted into the second through hole with the central gear 420 to realize the fixation of the central gear 420 relative to the frame 100. The above-mentioned power shaft 300 passes through the cylinder and can rotate in the inner hole of the cylinder to realize the avoidance of the power shaft 300.

[0036] In this embodiment, referring to Figure 2 and Figure 4 As shown, a second locking member 450 is provided on the connecting member 411. The second locking member 450 can be connected to or disengaged from one of the transmission gears 432. When the second locking member 450 is disengaged from the transmission gear 432, the box body 410 can rotate relative to the central gear 420.

[0037] In this embodiment, by providing the above-mentioned second locking member 450, when the second locking member 450 is connected to the transmission gear 432, since the rotation of the transmission gear 432 is restricted, the revolution of the transmission gear 432 relative to the central gear 420 is also restricted, so that the position of the box body 410 can be locked to avoid unexpected rotation of the box body 410 when the power shaft 300 does not drive the box body 410 to rotate; and when the second locking member 450 is disengaged from the transmission gear 432, the power shaft 300 can drive the box body 410 to rotate.

[0038] Overall, the working process of the steel pipe transfer device of this embodiment is as follows:

[0039] The rotation of the power shaft 300 drives the box body 410, and the two material supporting members 430 on the box body 410 rotate with the box body 410. Since the material supporting grooves 401 of the two material supporting members 430 always face upward; as the two material supporting members 430 rotate, the steel pipe can be moved from one side to the other side, for example, the steel pipe is placed from the steel pipe storage rack onto the conveying mechanism;

[0040] When the steel pipe is relatively short, it is possible to select to disengage the first locking member 440 on a part of the material supporting arm 400 from the power shaft 300 and connect the second locking member 450 to the transmission gear 432. At this time, this part of the material supporting arm 400 will be fixed relative to the central gear 420 and will not rotate with the power shaft 300. When this part of the material supporting arm 400 needs to work, just disengage the second locking member 450 from the transmission gear 432 and connect the first locking member 440 to the power shaft 300.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
