Description

Technical Field

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

[0002] Steel pipes are used for transporting fluids and powdery solids, exchanging heat energy, manufacturing mechanical parts and containers, and are also an economical steel material. There are extremely many types and specifications of steel pipes, and their performance requirements vary greatly; all of these should be differentiated according to changes in user requirements or working conditions. Typically, steel pipe processing involves gripping and transferring the pipe before further processing such as stamping.

[0003] In the use of existing steel pipe production gripping devices, it has been found that, in order to improve the gripping speed of steel pipes, powerful electromagnets are generally used to grip the steel pipes, and then they are transferred by steel wire ropes on a gantry. However, we have found that the electromagnets lack protective mechanisms when gripping steel pipes, and are prone to power failure during movement, which may cause the steel pipes to fall off the electromagnets. This reduces the efficiency and effectiveness of the gripping device, resulting in poor practicality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanism for protecting the steel pipe gripped by an electromagnet. This addresses the problem we have found where the lack of a protective mechanism for electromagnets gripping steel pipes leads to potential power outages during movement, causing the steel pipe to fall off the electromagnet. Therefore, this invention enhances the efficiency and effectiveness of the gripping device, thus improving its practicality in steel pipe production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe production gripping device, comprising a steel pipe body, a support plate, an electromagnet, and a hoisting assembly, wherein the hoisting assembly is fixedly installed at the top center of the support plate, an electromagnet is fixedly installed at the bottom of the support plate, the steel pipe body is attracted by the electromagnet, and a protective mechanism is provided at the top of the support plate.

[0006] The protective mechanism also includes a support block, a rotating plate, a mounting base, a first rod, a lifting plate, and a bracket. Two sets of brackets are symmetrically installed on the top of the support plate. The corresponding rotating plates are arranged on the front and rear sides of the support plate. The bottom of the corresponding rotating plate is fixedly connected to the top of the corresponding support block. The rotating plate is rotatably connected to the corresponding support plate through a rotating mechanism. Mounting bases are symmetrically installed on the top of the rotating plate. The corresponding mounting bases are hinged to the corresponding first rods. The tops of the multiple sets of mounting bases are symmetrically installed on the bottom of the lifting plate. The top areas of the multiple sets of first rods are hinged to the mounting bases on the corresponding lifting plates. The lifting plate is slidably connected to the bracket through a guide mechanism.

[0007] Furthermore, to facilitate the sliding of the lifting plate, the present invention includes an improvement in the guiding mechanism, which further includes guide rods and connecting plates. Multiple sets of guide rods are symmetrically installed on the inner wall of the bracket, and multiple sets of connecting plates are symmetrically installed on both sides of the lifting plate. The multiple sets of connecting plates are slidably connected to the corresponding guide rods.

[0008] Furthermore, to facilitate the rotation of the rotating plate, the present invention includes an improvement in the rotating mechanism, which further includes a rotating block and a fixed seat. The corresponding rotating block is fixedly connected to one side of the corresponding rotating plate, the fixed seat is connected to the top of the support plate, and the corresponding rotating block is hinged to the corresponding fixed seat.

[0009] Furthermore, to facilitate height adjustment of the lifting plate, the present invention includes a hydraulic push rod, wherein the mounting end of the hydraulic push rod is fixedly connected to the top of the bracket, and the output end of the hydraulic push rod is connected to the middle of the top of the lifting plate.

[0010] Furthermore, to improve installation stability, the present invention also includes stiffening plates, wherein stiffening plates are provided at the connection between the bracket and the support plate.

[0011] Furthermore, the present invention includes an anti-slip rubber pad, wherein the side of the support block that contacts the steel pipe body is adapted to the curvature of the corresponding steel pipe body, and the anti-slip rubber pad is fixedly connected to the inner wall of the support block.

[0012] Compared with the prior art, this utility model provides a steel pipe production gripping device, which has the following beneficial effects:

[0013] This steel pipe production gripping device offers the following advantages: 1. Enhanced Safety: The protective mechanism effectively prevents the steel pipe from falling due to electromagnet power failure. After the electromagnet grips the steel pipe, the coordinated action of the lifting plate, first rod, rotating plate, and support block forms a protective support below the pipe, greatly improving safety during handling and reducing the possibility of equipment damage and personnel injury due to accidental drops. 2. Enhanced Practicality: It solves the problem of poor practicality caused by power failure risks in existing gripping devices. The protective mechanism is simple to operate and does not affect the normal gripping and transfer process. It significantly improves the reliability of the device without adding too many complex operations, thereby improving the overall efficiency and effectiveness of the gripping device and meeting the needs of actual production. 3. Structural Stability: The guide rod and connecting plate in the guiding mechanism ensure the stability of the lifting plate during the lifting process, allowing it to smoothly drive the rotating plate. The rotating block and fixed seat of the rotating mechanism ensure the smoothness and stability of the rotating plate's rotation. In addition, the stiffening ribs at the connection between the bracket and the support plate enhance the structural strength of the bracket, making the entire protective mechanism more stable and durable. By using a mechanism that facilitates protection when the electromagnet grips the steel pipe, the aim is to solve the problem we found that the lack of a protective mechanism when the electromagnet is adsorbing and gripping the steel pipe makes it easy for the power to be cut off during movement, thus causing the steel pipe to fall off the electromagnet. Therefore, the efficiency and effectiveness of the gripping device are enhanced, thereby improving its practicality. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 A steel pipe production gripping device includes a steel pipe body 1, a support plate 2, an electromagnet 3, and a hoisting assembly 4.

The steel pipe body 1 is attracted by the electromagnet 3, and a protective mechanism is provided at the top of the support plate 2.

[0021] The protective mechanism also includes a support block 5, a rotating plate 6, a mounting base 7, a first rod 8, a lifting plate 9, and a bracket 10. Two sets of brackets 10 are symmetrically installed on the top of the support plate 2. The corresponding rotating plate 6 is arranged on the front and rear sides of the support plate 2. The bottom of the corresponding rotating plate 6 is fixedly connected to the top of the corresponding support block 5. The rotating plate 6 is rotatably connected to the corresponding support plate 2 through a rotating mechanism. The top of the rotating plate 6 is symmetrically installed with a mounting base 7. The corresponding mounting base 7 is hinged to the corresponding first rod 8. The tops of the multiple sets of mounting bases 7 are symmetrically installed on the bottom of the lifting plate 9.

[0026] Start the electromagnet 3 so that it attracts the steel pipe body 1.

[0027] Protection phase:

[0028] Start the hydraulic push rod 15. The output end of the hydraulic push rod 15 extends and pushes the lifting plate 9 to move downward along the guide rod 11.

[0029] As the lifting plate 9 descends, the first rod 8, which is hinged to the lifting plate 9, pushes the rotating plate 6 to rotate around the rotating mechanism composed of the rotating block 13 and the fixed seat 14.

[0030] During the rotation of the rotating plate 6, it drives the support block 5, which is fixedly connected to it, to move downwards towards the steel pipe body 1 until the support block 5 moves to the bottom of the steel pipe body 1 and contacts the steel pipe body 1. At this time, the anti-slip pad 17 is tightly attached to the surface of the steel pipe body 1, providing support and protection for the steel pipe body 1.

[0031] Transfer phase:

[0032] The gripping device, which has been protected and has attached the steel pipe body 1, is moved to the designated position using the hoisting assembly 4.

[0033] Release phase:

[0034] Once the designated position is reached, the hydraulic push rod 15 is activated to retract its output end, thereby raising the lifting plate 9.

[0035] During the ascent of the lifting plate 9, the first rod 8 pulls the rotating plate 6 to rotate in the opposite direction, and the support block 5 moves away from under the steel pipe body 1 and returns to the initial position.

[0036] Turn off electromagnet 3 and release the steel pipe body 1.

[0037] Reset phase:

[0038] Move the gripping device back to its initial position and wait for the next gripping task.
