By optimizing the design of the connecting rod and the connecting plate, this mechanism realizes the automatic opening and closing of the door, reduces energy consumption and maintenance costs, and improves the stability and service life of the door body.

[0027] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the accompanying drawings are not drawn in actual proportional relationship. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0028] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined or described in one drawing, it will not be necessary to further specifically discuss and describe it in the description of subsequent drawings.

[0029] To solve the technical problems in the background art, such as Figures 1-4 As shown, the present application provides a technical solution: a steel pipe rolling and clamping device, characterized as follows:

[0030] The fixed seat 1 is in a T shape for stabilizing the whole device, and a limiting hole 2 is provided thereon, and the limiting hole 2 is circular; the ring structure 3 is composed of an inner ring 4 and an outer ring 5, the inner ring 4 and the outer ring 5 are concentrically arranged and connected at the inner ring part, and a U-shaped semi-surrounding annular clamping groove 6 is formed in the middle. The annular clamping groove 6 is adapted to the limiting hole 2, so that the ring structure 3 can be clamped in the limiting hole 2; the protrusion 7 is fixed on the periphery of the inner ring 4, generally integrally formed with the inner ring 4 or fixed by welding, and a fixed block 8 is hinged to the protrusion 7; a through hole 9 is provided inside the fixed block 8, and the through hole 9 has internal threads; the positioning block 10 is hinged to the fixed seat 1, and the shape of the positioning block 10 is not limited, and a circular hole 11 is provided inside it; the screw rod 12 passes through the circular hole 11 and is threadedly connected to the fixed block 8; one end of the connecting rod 13 is hinged to the fixed seat 1, and the other end is connected to the roller 14, and the roller 14 abuts against the steel pipe to be processed and rolls on the steel pipe, and a plurality of rollers 14 cooperate to clamp and relax the steel pipe; the limiting block 15 is hinged to the inner ring 4, and a sliding groove 16 is provided inside. The connecting rod 13 can slide in the sliding groove 16; a sliding groove 16 is provided inside the limiting block 15, a plurality of connecting rods 13 are uniformly distributed along the outer periphery of the inner ring 4, a plurality of limiting blocks 15 are uniformly arranged along the axial direction of the inner ring 4, and the sliding grooves 16 of each connecting rod 13 and each limiting block 15 are all in one-to-one correspondence.

[0031] During use, the steel pipe is placed in the ring structure 3, and the roller 14 contacts the steel pipe, and preparation is made for adjustment operations. The screw rod 12 is rotated, so that the fixed block 8 drives the protrusion 7 to move along the screw rod 12, thereby driving the inner ring 4 to rotate; the rotation of the inner ring 4 causes the sliding groove 16 to also rotate. Because the sliding groove 16 is hinged to the inner ring 4, and at the same time the sliding groove 16 rotates around its own hinge axis, the connecting rod 13 slides in the sliding groove 16, and a plurality of connecting rods 13 achieve simultaneous swinging; each connecting rod 13 rotates around its hinge axis with the fixed seat 1, and the swinging of the connecting rod 13 causes the roller 14 to clamp the steel pipe, completing the clamping operation on the steel pipe with the corresponding pipe diameter; by adjusting the rotation direction of the screw rod 12, the roller 14 can be made to relax the steel pipe, completing the relaxation operation.

[0032] It should be noted that at the place where the inner surface of the limit hole 2 is connected and in contact with the annular slot 6, a certain number of ball bearings 17 are placed to form a structure similar to an annular bearing. In some embodiments, a certain number of grooves can be machined, and the number and positions of the grooves are determined according to actual requirements to ensure the uniform distribution of the ball bearings 17. Then, the ball bearings 17 are embedded in the grooves, and the size of the ball bearings 17 matches that of the grooves to ensure that the ball bearings 17 can be stably fixed on the inner surface. Finally, the limit hole 2 is connected to the annular slot 6 in an appropriate manner so that the ball bearings 17 are located on the inner surface where the limit hole 2 is in contact with the annular slot 6. When the limit hole 2 is in contact with the annular slot 6, the ball bearings 17 can effectively reduce the friction coefficient between the two, thereby reducing wear and increasing the service life. During the movement process, the ball bearings 17 roll between the limit hole 2 and the annular slot 6, making the movement smoother and reducing noise.

[0033] Furthermore, the diameter of the ball bearings 17 is adapted to the annular slot 6, enabling the ball bearings 17 to smoothly enter the interior of the annular slot 6. The adaptation relationship between the ball bearings 17 and the annular slot 6 ensures the movement performance and stability of the component.

[0034] It should be noted that the annular disk 18 is fixedly connected to the inner ring 4 by means such as welding or bolt connection to ensure a firm and reliable connection between the annular disk 18 and the inner ring 4. There is a certain distance between the annular disk 18 and the inner ring 4, which can accommodate the limit block 15 to ensure that the limit block 15 can be smoothly placed therein. The setting of the annular disk 18 increases the stability of the limit block 15. In addition, the fixed connection between the annular disk 18 and the inner ring 4 provides additional stability and support force.

[0035] Furthermore, both ends of the limit block 15 are hinged to the annular disk 18 and the inner ring 4 respectively and have the same hinge axis. This hinged manner ensures the movement coordination among the limit block 15, the annular disk 18, and the inner ring 4, and improves the stability of the limit structure.

[0036] It should be pointed out that the inner diameter of the annular disk 18 is equal to the inner diameter of the inner ring 4, so that when clamping a steel pipe, the annular disk 18 will not be hindered when dealing with a steel pipe with a large pipe diameter and can closely cooperate with the inner ring 4 to form a stable support structure. The material of the annular disk 18 should have high strength and wear resistance to ensure that it can bear a certain load during use and reduce wear at the same time.

[0037] It should be pointed out that one end of the connecting rod 13 is hinged to the fixed seat 1, and the other end extends into the ring structure 3. In the appendix Figure 1In it, the hinge axis of the connecting rod 13 and the fixed seat 1 is located on the outer periphery of the circular ring structure 3, that is, the hinge axis of the connecting rod 13 does not pass through the circular ring structure 3 but is located outside it, thus ensuring the stability and reliability of the device. The connecting rod 13 is made of high-strength material and has sufficient strength and stiffness to ensure that it will not deform during movement. The length of the connecting rod 13 can be adjusted according to actual needs to adapt to different working conditions.

[0038] It should be noted that the roller 14 is installed at one end of the connecting rod 13 and can freely rotate around the axis of the connecting rod 13 and can abut against the center position of the inner circular ring 4, so as to be able to clamp steel pipes with a smaller pipe diameter. The diameter of the roller 14 is slightly larger than the size of the connecting rod 13.

[0039] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
