Description

Technical Field

[0001] This utility model relates to a conveyor roller direct-connection lifting roller structure, belonging to the field of steel pipe straightening technology. Background Technology

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. It uses straightening rollers to compress the bar or other material, changing its straightness. Generally, there are multi-roller and two-roller straightening machines, which rely on the angle changes of two sets of rollers (with a concave center and hyperbolic shape) to straighten materials of different diameters. A steel pipe straightening machine, on the other hand, uses straightening rollers to compress the steel pipe, changing its straightness. Currently, steel pipes are linearly fed into the straightening machine via conveyor rollers. During operation, the steel pipes are placed directly on the rotating conveyor rollers. When the steel pipe enters the guide groove, it may swing its tail, damaging the conveyor rollers and reducing their service life. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a direct-connection lifting roller structure for conveyor rollers, which is simple in structure and convenient in operation. When the steel pipe enters the guide groove, it avoids the steel pipe tail swinging and damaging the conveyor roller, thereby improving the service life of the conveyor roller.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a conveyor roller direct-connection lifting roller structure, including a base, a plurality of roller units evenly spaced above the base, a plurality of horizontally arranged rotating shafts on the base, the rotating shafts corresponding to the roller units; the roller units are fixed on the corresponding rotating shafts, the rotating shafts are connected by a linkage mechanism, driving the linkage mechanism to swing, causing the rotating shafts to swing synchronously, so that each roller unit swings synchronously.

[0005] The linkage mechanism includes multiple swing arms, one end of each swing arm is fixed to a corresponding rotating shaft, and the multiple swing arms are fixedly connected by a connecting rod. Driving one swing arm to swing will cause the other swing arms and rotating shafts to swing synchronously.

[0006] It is also equipped with a horizontally arranged drive cylinder, the extension rod of which is fixedly connected to one of the swing arms.

[0007] The roller conveyor unit includes a roller conveyor mounting base, one end of which is fixed to a rotating shaft. Conveying rollers are respectively installed on the roller conveyor mounting base, and the central shaft of the conveying roller is fixedly connected to the output shaft of the reduction motor.

[0008] Compared with the prior art, the advantages of this utility model are as follows: a direct-connection lifting roller conveyor structure for conveyor rollers, in which a driving cylinder drives the connected swing arms to swing around a rotating shaft, and connecting rods connect each swing arm, enabling each swing arm to swing synchronously, thereby achieving synchronous lifting and lowering of each roller conveyor mounting base and conveyor roller. This application has a simple structure and is easy to operate. When the steel pipe enters the guide groove, it avoids the steel pipe tail swinging and damaging the conveyor roller, thus improving the service life of the conveyor roller.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , 2 As shown in Figure 3, this embodiment of a conveyor roller direct-connection lifting roller structure includes a base 1, with multiple roller conveyor units evenly spaced above the base 1. Multiple horizontally arranged rotating shafts 2 are mounted on the base 1, corresponding to the roller conveyor units. Both ends of the rotating shafts 2 are fixed to the base 1 via bearings, allowing the rotating shafts 2 to rotate on the base. The roller conveyor units are fixed to their corresponding rotating shafts. One end of a swing arm 4 is fixedly connected to each rotating shaft 2, and the multiple swing arms 4 are fixedly connected to each other via connecting rods 5, enabling synchronous movement of the multiple swing arms 4. A horizontally arranged drive cylinder 6 is provided on the base 1, with its extension rod fixedly connected to the other end of one of the swing arms 4. The drive cylinder 6 drives the connected swing arm to swing around its corresponding rotating shaft. Through the action of the connecting rods, the remaining swing arms swing synchronously around their corresponding rotating shafts, achieving synchronous lifting and lowering of each roller conveyor unit. When the roller conveyor unit rises, it is in a conveying state; when the roller conveyor unit descends, it facilitates the entry of the steel pipe into the guide trough, preventing the steel pipe from swinging off its tail and damaging the conveyor roller.

[0015] The aforementioned roller conveyor units each include a roller conveyor mounting base 3, one end of which is fixed to a rotating shaft 2. Conveying rollers 8 are respectively installed on the roller conveyor mounting base. The central shaft of the conveying roller 8 is fixedly connected to the output shaft of the reduction motor 7 through a coupling. The reduction motor drives the conveying roller to rotate, thereby realizing the conveying of steel pipes.

[0016] The hydraulic cylinder drives the connected swing arms to swing around the rotating shaft. The connecting rod connects each swing arm, enabling them to swing synchronously and achieve synchronous lifting and lowering of each roller conveyor mounting base and conveyor roller. This application has a simple structure and is easy to operate. When the steel pipe enters the guide trough, it avoids the steel pipe tail swinging and damaging the conveyor roller, thus improving the service life of the conveyor roller.

[0017] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
