Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe production gripping equipment, specifically a steel pipe production gripping device. Background Technology

[0002] The steel pipe production gripping device is a mechanical device used for the automated gripping, handling and stacking of steel pipes on the steel pipe production line. Its core function is to achieve precise gripping, efficient transfer and orderly stacking of steel pipes through mechanical structure and automated control system, thereby improving production efficiency, reducing labor intensity and ensuring operational safety.

[0003] Steel pipe production gripping devices precisely grip steel pipes using clamping components, and then achieve rapid transfer and precise stacking through a multi-axis linkage system. This not only significantly improves production efficiency and reduces manual labor intensity, but also avoids collision damage during steel pipe handling, ensuring product quality. However, existing steel pipe production gripping devices have insufficient adaptability in their gripping components, gaps in the mechanical structure, and a lack of supplementary clamping mechanisms. They are unable to adapt to differences in the surface of the steel pipes, resulting in unstable clamping. Even with electromagnet attraction, steel pipes may fall if the electromagnet malfunctions, causing safety accidents or damaging surrounding equipment. Utility Model Content

[0007] As a further embodiment of this utility model: the reinforced clamping mechanism includes a support plate, a back bracket, and an electric push rod. The support plate is fixedly connected to one end of the back side of the clamping plate, the back bracket is fixedly connected to the other end of the back side of the clamping plate, and the electric push rod is fixedly connected to the top of the back bracket; a sliding pressure plate and an arc-shaped rubber patch are also included. The sliding pressure plate is slidably connected to the middle of the clamping plate, and the arc-shaped rubber patch is fixedly connected to one end of the front side of the sliding pressure plate.

[0008] As a further embodiment of this utility model: the support mechanism includes a second cylinder and a support plate, the second cylinder is fixedly connected to the middle of the bottom bracket, and the support plate is fixedly connected to the movable end of the second cylinder; an arc-shaped support block and a ball bearing, the arc-shaped support block is fixedly connected to one end above the support plate, and the ball bearing is movably embedded in one end of the inner side of the arc-shaped support block; the support plate and the arc-shaped support block are vertically and slidably connected to the first clamping plate and the second clamping plate.

[0009] As a further embodiment of this utility model: the sliding base and the lead screw are threadedly connected, the other end of the lead screw passes through the fixed long box frame and is fixedly connected to the output end of the motor, the bidirectional lead screw is threadedly connected to the clamping plate and the clamping plate, the other end of the bidirectional lead screw passes through the movable box frame and is fixedly connected to the output end of the motor, and the back of the clamping plate is also provided with a reinforced clamping mechanism structure.

[0010] As a further embodiment of this utility model: the connecting frame, the movable box frame, the second motor, the first clamping plate, the second clamping plate, and the bidirectional lead screw are all provided in two sets, and the two sets of connecting frames are symmetrically arranged at the bottom of the sliding base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the device is placed in front of the steel pipe production equipment. Motor 1 drives the lead screw to rotate, causing the sliding base to slide to a suitable gripping position. Clamping plates 1 and 2 are perpendicular to the support mechanism. Cylinder 1 pushes the moving frame downwards, positioning the clamping plates above the support mechanism. Cylinder 2 adjusts the height of the support plate. The arc-shaped support block and ball bearings provide adaptive support for the steel pipe, ensuring stable support for steel pipes of different diameters. Motor 2 drives the bidirectional lead screw to rotate, causing the clamping plates to slide towards each other to form a clamping state and provide protection, ensuring even force distribution on the steel pipe and reducing the risk of slippage, shaking, safety accidents, and impact on subsequent processes. After the clamping plates clamp the steel pipe, cylinder 2 moves the support mechanism downwards to avoid interference. The electric push rod then pushes the sliding pressure plate, causing the arc-shaped rubber pad to adhere to the surface of the steel pipe. The same operation is performed on the back of the second clamping plate. Multiple sets of arc-shaped rubber pads increase the contact area, improve clamping stability, and adapt to different specifications of steel pipes. This avoids the difficulty in adapting to the surface characteristics of different specifications of steel pipes when using only the first and second clamping plates, which cannot ensure reliable clamping force under various conditions. This reduces the problem of clamping instability caused by differences in specifications. Finally, the first motor starts again, and the sliding base slides the steel pipe to the designated position. The ground support frame, top mounting frame, and mounting plate ensure the stability of the device and do not affect the lowering of the steel pipe, ensuring a smooth and safe lowering.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figures 1 to 6In this embodiment of the utility model, a steel pipe production gripping device includes: a fixed long box frame 1, which serves as the basic frame of the entire device, providing an installation foundation and support for other components, ensuring the overall stability and structural integrity of the device; and a ground support frame 2 is fixedly connected to one end of the fixed long box frame 1 to support the fixed long box frame 1 and ensure the stability of the device during steel pipe gripping and handling.

[0024] A motor 3 is fixedly connected to the outside of the fixed long box frame 1, and a sliding base 4 is slidably connected inside the fixed long box frame 1. A lead screw 5 is rotatably connected to the inside of the fixed long box frame 1. The rotation of the motor 3 drives the lead screw 5 to rotate, thereby driving the sliding base 4 to slide inside the fixed long box frame 1, realizing the function of adjusting the position of the sliding base 4 so as to accurately reach the position suitable for gripping the steel pipe.

[0025] A connecting frame 6 is fixedly connected to the bottom of the sliding base 4. A cylinder 7 is fixedly connected to one end inside the connecting frame 6. The connecting frame 6 serves as a support for fixing the cylinder 7. A movable box frame 8 is fixedly connected to the movable box frame 8. A motor 9 is fixedly connected to the outside of the movable box frame 8 as a driving component. A clamping plate 10 is slidably connected to one end of the bottom of the movable box frame 8, and a clamping plate 11 is slidably connected to the other end of the bottom of the movable box frame 8. The movable box frame 8 is pushed downward by the cylinder 7, causing the clamping plates 10 and 11 to move downward, which can be used to clamp the pipe.

[0026] The back of the clamping plate 10 is provided with a reinforced clamping mechanism 12, which serves as an additional clamping component after the clamping plate 10 and the clamping plate 2 11 clamp the steel pipe, preventing gaps from causing unstable clamping. The inner side of the movable box frame 8 is rotatably connected to a bidirectional lead screw 13, which is driven to rotate by the motor 2 9. The rotation of the bidirectional lead screw 13 will cause the clamping plate 10 and the clamping plate 2 11 to slide towards each other along the bottom of the movable box frame 8, thereby clamping.

[0027] The lower inner side of the floor support frame 2 is fixedly connected to a bottom bracket 14. The bottom bracket 14 has a support mechanism 15 in the middle. The bottom bracket 14 and the support mechanism 15 provide the installation foundation and support. The support mechanism 15 supports the steel pipe. The sliding base 4 and the lead screw 5 are threadedly connected. The other end of the lead screw 5 passes through the fixed long box frame 1 and is fixedly connected to the output end of the motor 1 3. The bidirectional lead screw 13 is threadedly connected to the clamp 1 10 and the clamp 2 11. The other end of the bidirectional lead screw 13 passes through the movable box frame 8 and is fixedly connected to the output end of the motor 2 9. The back of the clamp 2 11 is also provided with a reinforced clamping mechanism 12. There are two sets of connecting frames 6, movable box frame 8, motor 2 9, clamp 1 10, clamp 2 11 and bidirectional lead screw 13. The two sets of connecting frames 6 are symmetrically arranged at the bottom of the sliding base 4.

[0028] Reference Figure 1The other end of the fixed long box frame 1 is fixedly connected to the top mounting frame 16, and the top of the top mounting frame 16 is fixedly connected to the mounting plate 17. The design of the top mounting frame 16 and the mounting plate 17 takes into account that when the steel pipe is clamped and moved to the designated position, it will not interfere with the lowering operation of the steel pipe. This design not only improves the stability of the device, but also ensures the smoothness and safety of the steel pipe when it is lowered.

[0029] Reference Figure 1 , Figure 3 and Figure 5 The enhanced clamping mechanism 12 includes a support plate 1201, a back support 1202, and an electric push rod 1203. The support plate 1201 is fixedly connected to one end of the back of the clamping plate 10, the back support 1202 is fixedly connected to the other end of the back of the clamping plate 10, and the electric push rod 1203 is fixedly connected to the top of the back support 1202.

[0030] The sliding pressure plate 1204 and the arc-shaped rubber patch 1205 are slidably connected to the middle of the clamping plate 10. The arc-shaped rubber patch 1205 is fixedly connected to one end of the front of the sliding pressure plate 1204. The support plate 1201 and the back bracket 1202 are fixedly connected. The output end of the electric push rod 1203 is fixedly connected to the sliding pressure plate 1204. There are multiple sets of arc-shaped rubber patches 1205, which are symmetrically arranged on the front of the sliding pressure plate 1204. After the steel pipe is clamped by the clamping plate 10 and the clamping plate 2 11, the electric push rod 1203 pushes the sliding pressure plate 1204 through the clamping plate 10 and moves it toward the steel pipe, so that the arc-shaped rubber patch 1205 is tightly attached to the surface of the steel pipe. The reinforced clamping mechanism 12 on the back of the clamping plate 2 11 operates in the same way. The design of multiple sets of arc-shaped rubber patches 1205 can increase the contact area with the steel pipe and improve the stability of clamping.

[0031] Reference Figure 1 and Figure 6 The support mechanism 15 includes a second cylinder 1501 and a support plate 1502. The second cylinder 1501 is fixedly connected to the middle of the bottom bracket 14, and the support plate 1502 is fixedly connected to the movable end of the second cylinder 1501.

[0032] The arc-shaped support block 1503 and the ball bearing 1504 are fixedly connected to one end of the support plate 1502. The arc-shaped support block 1503 is movably embedded in one end of the inner side of the arc-shaped support block 1503. The support plate 1502 and the arc-shaped support block 1503 are vertically and slidably connected to the clamping plate 10 and the clamping plate 11. The support plate 1502 is raised or lowered by the cylinder 1501, so that the arc-shaped support block 1503 and the ball bearing 1504 reach a suitable height position to provide support and movement for the steel pipe. The adaptive support method can be adjusted according to steel pipes of different diameters to ensure effective support regardless of the size of the steel pipe.

[0033] The working principle of this utility model is as follows:

[0034] Step one: During use, place the entire device in front of the steel pipe production equipment. When the produced pipe is sent out by the production line, motor 3 first drives the lead screw 5 to rotate. The rotation of the lead screw 5 causes the sliding base 4 to slide along the axis of the lead screw 5 inside the fixed long box frame 1, thereby adjusting the position of the sliding base 4 to a suitable position to grip the steel pipe, until the clamping plates 10 and 11 below it are perpendicular to the support mechanism 15. Then, cylinder 7 on the connecting frame 6 pushes the moving box frame 8 downward, so that clamping plates 10 and 11 are above the support mechanism 15. Then, cylinder 1501 drives the support plate 1502 to rise or fall, so that the arc-shaped support block 1503 and the ball bearing 1504 reach the appropriate height position to provide support and movement for the steel pipe. The adaptive support method can be adjusted according to steel pipes of different diameters. To ensure effective support regardless of changes in the size of the steel pipe, motor 29 drives the bidirectional lead screw 13 to rotate. The rotation of the bidirectional lead screw 13 causes clamping plates 10 and 11 to slide towards each other along the bottom of the movable box frame 8, forming a clamping state and providing protection on both sides to prevent the steel pipe from deviating when moving on the ball bearings 1504. This method ensures more even force distribution during the gripping and handling of the steel pipe, reducing the risk of slippage or shaking. It also avoids potential safety accidents or impacts on subsequent processing steps caused by shaking when the steel pipe is first discharged. Then, the movement of clamping plates 10 and 11 gradually clamps the steel pipe. At this time, the support plate 1502, arc-shaped support block 1503, and ball bearings 1504 complete their support tasks and can be driven downward by cylinder 2 1501 to prevent interference with the movement of the clamped steel pipe.

[0035] Step 2: After clamping the steel pipe with clamping plates 10 and 11, the sliding pressure plate 1204 is pushed through clamping plate 10 and moved towards the steel pipe by electric push rod 1203, so that the arc-shaped rubber patch 1205 is tightly attached to the surface of the steel pipe. The reinforced clamping mechanism 12 on the back of clamping plate 11 is operated in the same way. The design of multiple sets of arc-shaped rubber patches 1205 can increase the contact area with the steel pipe, improve the stability of clamping, and avoid the difficulty in adapting to the surface characteristics of different specifications of steel pipes when using clamping plates 10 and 11 alone. It is difficult to ensure reliable clamping force under various conditions, and reduce the problem of clamping instability caused by specification differences. After clamping plates 10 and 11 and reinforced clamping mechanism 12 firmly clamp the steel pipe, motor 3 is started again, driving screw 5 to rotate, so that sliding base 4 carries the gripped steel pipe and slides along the inside of fixed long box frame 1 to the designated position.

[0036] Step three, the ground support frame 2, the top mounting frame 16 and the mounting plate 17 are for the stability of the entire device. The design of the top mounting frame 16 and the mounting plate 17 is specifically designed to ensure that the steel pipe will not be disturbed when it is moved to the designated position after being clamped. This design not only improves the stability of the device, but also ensures the smoothness and safety of the steel pipe when it is lowered.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
