Abstract
The utility model relates to a lifting rotation roller which comprises a supporting plate, rotation roller bodies, a base, a guide rod, a guide sleeve and an oil cylinder. The supporting plate is provided with a set of the rotation roller bodies. The guide rod with the long diameter is arranged between the supporting plate and the base. The guide sleeve is arranged outside the guide rod. The oil cylinder is arranged in the guide rod. The two ends of the oil cylinder are respectively and fixedly connected with the base and the supporting plate through lug rings. The sliding face of the guide rod and the sliding face of the guide sleeve are processed through chromizing. The diameter of the guide rod is 500-800mm. The lifting rotation roller is simple in structure and reliable in performance, lowers the omission ratio and labor intensity of inspection personnel, and improves production efficiency.
Description
Technical field
The utility model relates to a kind of lifting rotation roller, relates in particular to a kind of for the lifting rotation roller on spiral welded pipe production line.
Background technology
Rotating roller is a kind of general subsidiary engine on spiral welded pipe production line, is divided into fixedly two kinds of rotating rollers and lifting rotation roller, and its effect is to drive steel pipe rotary.Rotating roller is mainly used in the operations such as flame tack, x-ray examination, ultrasonic examination, product inspection, and the performance quality of rotating roller all has a great impact above-mentioned operation, and what wherein ultrasonic examination operation was used is the lifting rotation roller.
the structure of the lifting rotation roller of prior art as shown in Figure 1, find also to exist in actual use some problems, at first adopt the guide post 4 of two minor axis due to the lifting guiding of rotating roller 2, its guiding length is short, rock thereby produce when causing 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, 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, this structure poor synchronization, just make the probe tracking weld seam very difficult, increased loss and reviewer's labour intensity, reduced production efficiency.
The utility model content
The utility model purpose is that a kind of Stability Analysis of Structures is provided in order to overcome the deficiencies in the prior art, oil cylinder convenient disassembly and two lifting rotation rollers that the rotating roller synchronism is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lifting rotation roller, comprise gripper shoe, rotating roller, base, guide post, fairlead and oil cylinder, 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 base; Described guide post is provided with fairlead outward; Be provided with oil cylinder in described guide post; Described oil cylinder two ends connect respectively by earrings and are fixedly linked with base and gripper shoe.
Preferably, the sliding surface of described guide post and fairlead adopts chromium plating to process.
Preferably, the diameter of described guide post is 500-800mm.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Lifting rotation roller of the present utility model, 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 solutions of the utility model are described further:
Accompanying drawing 1 is the lifting rotation roll structure schematic diagram of prior art;
Accompanying drawing 2 is lifting rotation roll structure schematic diagram of the present utility model;
Wherein: 1, gripper shoe; 2, rotating roller; 3, base; 4, guide post; 5, fairlead; 6, oil cylinder.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of lifting rotation 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 base 3; The outer fairlead 5 that is provided with of described guide post 4; Be provided with oil cylinder 6 in described guide post 4; Described oil cylinder 6 two ends connect respectively by earrings and are fixedly linked with base 3 and gripper shoe 1; The sliding surface of described guide post 4 and fairlead 5 adopts chromium plating to process; The diameter of described guide post 4 is 500-800mm.
lifting rotation roller of the present utility model, the lifting guide structure 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, guaranteed that like this cylinder force is reasonable, 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 gets final product, every group of rotating roller lifting controlled by one group of hydraulic valve separately, the adjustable height of every group of rotating roller is controlled by mechanical position limitation, like this as long as guarantee that the machinery adjustment is highly consistent, can realize that two groups of rotating rollers rear height that hoists is consistent, it is simple in structure, dependable performance, reduced loss and reviewer's labour intensity, improved production efficiency.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
