Abstract
The invention discloses a lifting rotation roller which comprises a supporting plate, rotation rollers, a base, a guiding rod, a guiding sleeve and an oil cylinder. A group of rotation rollers are arranged on the supporting plate. A guiding rod with a long diameter is arranged between the supporting plate and the base. The guiding sleeve is arranged outside the guiding rod. The oil cylinder is arranged in the guiding rod. The two ends of the oil cylinder are fixedly connected with the base and the supporting plate through rings respectively. Sliding faces of the guiding rod and the guiding sleeve undergo chromate finish. The guiding rod has the diameter ranging from 500mm to 800mm. The lifting rotation roller is simple in structure, reliable in performance, capable of reducing an omission rate and labor intensity of detecting staff and capable of improving production efficiency.
Description
Technical field
The present invention relates to a kind of lifting rotating roller, relate in particular to a kind of for the lifting rotating roller on the spiral welded pipe production line.
Background technology
Rotating roller is a kind of general subsidiary engine on the spiral welded pipe production line, is divided into fixedly two kinds of rotating rollers and lifting rotating roller, and its effect is to drive the steel pipe rotation.Rotating roller is mainly used in operations such as flame tack, x-ray examination, ultrasonic examination, product inspection, and the performance quality of rotating roller has very big influence to above-mentioned operation, and what wherein ultrasonic examination operation was used is the lifting rotating roller.
The structure of the lifting rotating roller of prior art as shown in Figure 1, find also to exist some problems in actual use, at first because the lifting of rotating roller 2 guiding adopts the guide post 4 of two minor axis, its guiding length is short, rock thereby produce when causing the steel pipe lifting, structural instability, secondly the afterbody of oil cylinder 6 is connected to the flange connection, head is connected to sphere and connects, so in use, the controlled variable of oil cylinder 6 is limited, and oil cylinder 6 force-bearing situations are bad, and dismounting is very inconvenient during oil cylinder 6 maintenance, and Hydraulic Synchronizing Valve is adopted in the lifting of two rotating rollers 2, and this structure poor synchronization just makes the probe tracking weld seam very difficult, increase loss and reviewer's labour intensity, reduced production efficiency.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of Stability Analysis of Structures, oil cylinder convenient disassembly and two lifting rotating rollers that the rotating roller synchronism is good.
Technical solution of the present invention is achieved in that.
A kind of lifting rotating roller comprises gripper shoe, rotating roller, base, guide post, fairlead and oil cylinder, and described gripper shoe is provided with one group of rotating roller, is provided with the guide post of major diameter between described gripper shoe and the base; Described guide post is provided with fairlead outward; Be provided with oil cylinder in the described guide post; Described oil cylinder two ends are fixedly linked with base and gripper shoe respectively by the earrings connection.
Preferably, the sliding surface of described guide post and fairlead adopts chromium plating to handle.
Preferably, the diameter of described guide post is 500-800mm.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Lifting rotating roller of the present invention, the diameter of guide post is long, and its steering capability is good, and is steadily reliable during the rotating roller lifting, and oil cylinder is that earrings connects, and has guaranteed that cylinder force is reasonable, and the oil cylinder repair demolition is convenient; And every group of rotating roller lifting adopts independent one group of hydraulic valve to control, and its synchronism is good, is adding man-hour like this, and probe can trace into weld seam, has reduced loss and reviewer's labour intensity, has improved production efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the lifting rotating roller structural representation of prior art;
Accompanying drawing 2 is lifting rotating roller structural representation of the present invention;
Wherein: 1, gripper shoe; 2, rotating roller; 3, base; 4, guide post; 5, fairlead; 6, oil cylinder.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of lifting rotating roller as shown in Figure 2, comprise gripper shoe 1, rotating roller 2, base 3, guide post 4, fairlead 5 and oil cylinder 6, described gripper shoe 1 is provided with one group of rotating roller 2, is provided with the guide post 4 of major diameter between described gripper shoe 1 and the base 3; The described guide post 4 outer fairleads 5 that are provided with; Be provided with oil cylinder 6 in the described guide post 4; Described oil cylinder 6 two ends are fixedly linked with base 3 and gripper shoe 1 respectively by the earrings connection; The sliding surface of described guide post 4 and fairlead 5 adopts chromium plating to handle; The diameter of described guide post 4 is 500-800mm.
Lifting rotating roller of the present invention, the lifting guide frame of its rotating roller adopts a long guide post, guide post and fairlead sliding surface adopt plating to press against processing, its guiding length is long, such structure directing is functional, steadily reliable during the rotating roller lifting, the connected mode of oil cylinder changes earrings into and connects, and has guaranteed that like this cylinder force is reasonable, and the oil cylinder repair demolition is convenient, when dismounting, only need utilize fairlead and guide post installing/dismounting fabrication hole that bearing pin is pulled down and get final product, every group of rotating roller lifting is separately by one group of hydraulic valve control, and the adjustable height of every group of rotating roller is controlled by mechanical position limitation, adjust highly consistent as long as guarantee machinery like this, can realize that two groups of rotating rollers are highly consistent after hoisting, it is simple in structure, dependable performance, reduce loss and reviewer's labour intensity, improved production efficiency.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
