When the diameter of the steel pipe is small, multiple steel pipes may be pushed to the quantitative pipe feeding device, causing the device to fail to realize the orderly rolling of the steel pipes to the inspection station one by one, and the upper surface of the pipe storage rack is a gradually downward plane from the inlet to the outlet, but in the next process, there is a height higher than the height of the rack, which makes it impossible to push the steel pipes to the next process with an increased elevation. Summary of the invention

[0004] The embodiment of the present application provides a steel pipe positioning and pulling device, comprising:

[0005] A platform mechanism, the platform mechanism comprising a platform supported on the ground for positioning the conveying steel pipe, a V-shaped groove provided on the platform for positioning, and a pipe-pumping mechanism provided in the V-shaped groove;

[0006] The platform is divided into a first platform for feeding pipes and a second platform with an adjustable height to be level with the height of the subsequent process platform by a V-shaped groove;

[0007] The pipe shifting mechanism includes a shift fork disposed in the V-shaped groove and detachably connected to the second platform and a driving mechanism for driving the shift fork to rotate and lift to shift the pipe. The shift fork and the driving mechanism are detachably connected so that shift forks of different lengths can be replaced to adapt to the height of the second platform.

[0008] In some embodiments, the height of the shift fork near one end of the first platform is lower than the height of the first platform;

[0009] The height of the shift fork near one end of the second platform is higher than the height of the second platform.

[0010] In some embodiments, the second platform includes a base and a conveying platform disposed above the base;

[0011] A cavity is provided inside the base, and an adjusting mechanism for adjusting the height of the conveying platform is arranged inside the cavity.

[0021] The beneficial effects of the technical solution provided by this application include:

[0022] The V-shaped groove is opened between the first platform and the second platform. By opening the V-shaped groove on the platform, the steel pipe will fall into the V-shaped groove when feeding and be carried by the shifting fork, so that the steel pipe can be positioned during supply and then the pipe shifting operation can be performed, thereby preventing the platform from being a straight line segment, causing the steel pipe to automatically roll from the storage rack to the inspection post during supply, causing harm to the staff of the next process, disrupting the process rhythm, and reducing work efficiency.

The shift fork and the driving mechanism are detachably connected. When the height of the second platform is increased, the shift fork and the driving mechanism can be quickly disassembled, and the shift fork and the second platform can also be quickly disassembled. Then, shift forks of different lengths can be replaced to adapt to the height of the second platform after lifting. The structure of the detachable connection between the shift fork and the driving mechanism is the same as the structural principle of the detachable connection between the shift fork and the second platform. The shift fork and the driving mechanism are detachably connected in an articulated manner, and the shift fork and the second platform are also detachably connected in an articulated manner.

[0025] The detachable shift fork can be replaced with shift forks with different opening angles, making it easy to position steel pipes of different diameters. This can prevent the situation where the steel pipe has a small diameter and the shift fork has a large opening angle, causing multiple steel pipes to roll into the shift fork. It can also prevent the situation where the steel pipe has a large diameter and the shift fork has a small opening angle, causing the steel pipe to be unable to enter the shift fork for positioning and supply.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The embodiment of the present application provides a steel pipe positioning and pipe-moving device, which can solve the problem that when the diameter of the steel pipe is small, multiple steel pipes may be moved to the quantitative pipe feeding device, causing the device to be unable to realize the orderly rolling of the steel pipes to the inspection station one by one, and the upper surface of the pipe storage rack is a gradually downward plane from the inlet to the outlet, but in the next process, there is a height higher than the height of the rack, resulting in the problem that the steel pipes cannot be moved to the next process with an increased elevation.

[0035] See also Figure 1-5 As shown, the embodiment of the present application provides a steel pipe positioning and pipe pulling device, comprising:

[0036] The platform mechanism includes a platform supported on the ground for positioning the conveying steel pipe, a V-shaped groove 17 opened on the platform for positioning, and a pipe-pumping mechanism arranged in the V-shaped groove 17.

[0037] The platform is divided into a first platform 11 for feeding pipes and a second platform 2 with an adjustable height to be level with the subsequent process platform by a V-shaped groove 17 .

[0038] Among them, the V-shaped groove 17 is opened between the first platform 11 and the second platform 2. By opening the V-shaped groove 17 on the platform, the steel pipe will fall into the V-shaped groove 17 when feeding and be carried by the fork 1, so that the steel pipe can be positioned during supply and then the pipe shifting operation can be performed, thereby avoiding the platform being a straight line segment, causing the steel pipe to automatically roll from the storage rack to the inspection post at will during supply, causing harm to the staff of the next process, and causing the process rhythm to be disrupted and the work efficiency to be reduced.

[0039] The pipe shifting mechanism includes a fork 1 disposed in the V-shaped groove 17 and detachably connected to the second platform 2 and a driving mechanism for driving the fork 1 to rotate and lift to shift the pipe. The fork 1 and the driving mechanism are detachably connected so that the fork 1 of different lengths can be replaced to adapt to the height of the second platform 2.

[0040] The fork 1 is used to provide transportation power for the steel pipes that have fallen into the V-shaped groove 17, so that the supply of the steel pipes can be carried out in an orderly manner and chaos can be avoided. The fork 1 and the driving mechanism are detachably connected. When the height of the second platform 2 is increased, the fork 1 and the driving mechanism can be quickly disassembled, and the fork 1 and the second platform 2 can also be quickly disassembled. Then, the forks 1 of different lengths can be replaced to adapt to the height of the second platform 2 after lifting. The structure of the detachable connection between the fork 1 and the driving mechanism is the same as the structural principle of the detachable connection between the fork 1 and the second platform 2. The fork 1 and the driving mechanism are detachably connected in an articulated manner, and the fork 1 and the second platform 2 are also detachably connected in an articulated manner.

[0041] The detachable shift fork 1 can be replaced with shift forks 1 of different opening angles, so that steel pipes of different diameters are easy to position, and it is avoided that the steel pipe has a small diameter and the opening angle of the shift fork 1 is large, resulting in multiple steel pipes rolling into the shift fork 1, and it is also avoided that the steel pipe has a large diameter and the opening angle of the shift fork 1 is small, resulting in the steel pipe being unable to enter the shift fork 1 for positioning and supply.

[0042] In some optional embodiments, see Figure 1-3 and Figure 5 As shown, in the steel pipe positioning and shifting device, the height of the shift fork 1 near the first platform 11 is lower than the height of the first platform 11 , and the height of the shift fork 1 near the second platform 2 is higher than the height of the second platform 2 .

[0043] Among them, the hinged structure between the second platform 2 and the fork 1 is located on the side of the second platform 2 close to the first platform 11, and is located at the diagonal of the rolling surface of the steel pipe, wherein the two connecting plates in the hinged structure are located at the diagonal of the rolling surface of the steel pipe, so that the fork 1 and the two connecting plates can be detachably hinged through the rotating cylinder 13 and the bolt 14, so that when the fork 1 is driven to be lifted by the driving mechanism, because the hinge is located higher than the second platform 2, the height of the end of the fork 1 connected to the second platform 2 is higher than the second platform 2, so that the steel pipe in the fork 1 can roll onto the second platform 2 and apply gravity inertia to make its rolling smoother, and avoid the height of the fork 1 being lower than the second platform 2, which will cause the steel pipe to be blocked and limited by the second platform 2, so that the steel pipe cannot continue to roll and supply.

[0044] The height of the fork 1 close to the first platform 11 is lower than that of the first platform 11 so that the steel pipe will not be blocked and limited by the fork 1 when traveling, so that the steel pipe can smoothly roll into the fork 1 for positioning, and then be transported out through the fork 1.

[0045] In some optional embodiments, see Figure 1 and Figure 5 As shown, in the steel pipe positioning and pipe-pulling device, the second platform 2 includes a base 5 and a conveying platform 3 arranged above the base 5;

[0046] A cavity 4 is formed inside the base 5 , and an adjusting mechanism for adjusting the height of the conveying platform 3 is arranged inside the cavity 4 .

[0047] In this embodiment, the adjustment mechanism includes a sleeve 9 rotatably connected to the bottom of the cavity 4, a threaded rod 16 disposed in the sleeve 9, and a power device for driving the sleeve 9 to rotate;

[0048] One end of the threaded rod 16 away from the sleeve 9 extends out of the sleeve 9 and passes through the base 5 to be connected to the conveying platform 3 .

[0049] In this embodiment, the power device is a motor 8 .

[0050] In this embodiment, there may be multiple sleeves 9 and threaded rods 16, which are placed at different positions in the cavity 4, so that the lifting and lowering of the conveying platform 3 is more stable and smooth, and the skewness caused by uneven force is avoided. A motor 8 can simultaneously drive multiple sleeves 9 to rotate, and the sleeves 9 drive the threaded rods 16 to rotate to lift the conveying platform 3.

[0051] In some optional embodiments, see Figure 1 and Figure 5 As shown, in the steel pipe positioning and pipe-pulling device, the motor 8 is connected to the sleeve 9 through a transmission belt mechanism, and the transmission belt mechanism includes a first transmission wheel 6 arranged on the outside of the sleeve 9, a transmission shaft 19 arranged on the output shaft of the motor 8, a second transmission wheel 20 arranged on the outside of the transmission shaft 19, and a transmission belt 7 connected to the first transmission wheel 6 and the second transmission wheel 20.

[0052] By arranging a plurality of second transmission wheels 20 on the outer side of the transmission shaft 19 on the output shaft of the motor 8 , it is possible to drive a plurality of sleeves 9 to rotate simultaneously.

[0053] The motor 8 drives the transmission shaft 19 to rotate, and the transmission shaft 19 drives the second transmission wheel 20 to rotate. The second transmission wheel 20 rotates and is transmitted to the first transmission wheel 6 through the transmission belt 7. Then the first transmission wheel 6 drives the sleeve 9 to rotate, so that the threaded rod 16 can be raised and lowered, so that it drives the conveying platform 3 to rise and fall.

[0054] In some optional embodiments, see Figure 1 and Figure 4-5 As shown, in the steel pipe positioning and shifting device, a groove 12 is provided at the bottom of the shifting fork 1, a detachable hinge mechanism is provided in the groove 12, and a driving mechanism is connected to the hinge mechanism.

[0055] In this embodiment, the hinge mechanism includes a bolt 14 penetrating the groove 12, a nut 15 for fixing the bolt 14, and a rotating cylinder 13 sleeved on the outside of the bolt 14;

[0056] The driving mechanism is connected to the drum 13 .

[0057] In this embodiment, the driving mechanism is an oil cylinder 10 , and a piston rod of the oil cylinder 10 is connected to a rotating drum 13 .

[0058] The oil cylinder 10 drives the fork 1 to rise. When the fork 1 rises, the fork 1 is gradually turned over by the rotating drum 13 and the hinged structure with the second platform 2, so that the V-shaped angle of the fork 1 faces the direction of the next process, and the end of the fork 1 connected to the second platform 2 is inclined, so that the steel pipe can roll downhill to provide power.

[0059] When the shift fork 1 needs to be replaced, the nut 15 connected with the oil cylinder 10 and the second platform 2 is loosened, and then the bolt 14 is pulled out to disassemble the shift fork 1. Then, an appropriate shift fork 1 is replaced, and the bolt 14 is inserted and passed through the rotating cylinder 13 on the shift fork 1. Then, the nut 15 is screwed onto the bolt 14, and the bolt 14 is fixed and cannot rotate to complete the replacement.

[0060] Working principle and process of this application:

[0061] When the steel pipe is fed, it rolls into the fork 1, and then the fork 1 is driven to rise by the cylinder 10. When the fork 1 rises, the fork 1 is gradually turned over by the rotating drum 13 and the hinged structure with the second platform 2, so that the V-shaped angle of the fork 1 faces the direction of the next process, and the end of the fork 1 connected to the second platform 2 is inclined, so that the steel pipe can roll downhill to provide power, thereby feeding the steel pipe.

[0062] The motor 8 drives the transmission shaft 19 to rotate, and the transmission shaft 19 drives the second transmission wheel 20 to rotate. The second transmission wheel 20 rotates and is transmitted to the first transmission wheel 6 through the transmission belt 7. Then the first transmission wheel 6 drives the sleeve 9 to rotate, so that the threaded rod 16 can be raised and lowered, so that it drives the conveying platform 3 to rise and fall.
