Abstract

The invention relates to an adjustable roller carrier. A roller device capable of deflecting around a roller carrier base is adopted, and the roller carrier is provided with the arc base so that the heights of the self structure and steel pipe welding parts are reduced. A roller carrier hydraulic jack and a hydraulic power station and a solenoid valve of the roller carrier are all placed inside a hollow roller carrier support so that the height and the center distance of rollers can be adjusted, and the adjustable roller carrier has the advantages of being integrally compact in structure and small in occupied space, achieves steel pipe rotating, fast lifting and rail transport in narrow spaces, is convenient to operate and high in safety, enables quality and efficiency of steel pipe welding in tunnels or similar space limited places to be improved, and is broadened in use range.

Description

Technical field

[0001] The invention relates to a roller frame, in particular to an adjustable roller frame. Background technique

[0002] The roller frame is a device that drives the cylindrical (or conical) weldment to rotate by means of the friction between the weldment and the active roller. Roller racks can be divided into self-adjusting, adjustable, flat-car type, tiltable, anti-axial movement and other forms. Among them, the adjustable roller rack includes a base, a driving roller component and a driven roller component. At present, there are three types of adjustable roller racks: manual screw adjustable, manual bolt displacement and electric skateboard displacement. The center distance of the rollers is manually adjusted to meet different diameters of weldments. Because all current adjustable roller racks have the defects of large structure size and high center height, manual or electric slide plate adjustment structure causes the steel pipe to rise and fall slowly, and...

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the drawings.

[0027] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0028] Such as figure 1 — Image 6 Shown, an adjustable roller stand, in which Figure 1-3 Is the active roller frame, Figure 4-6 It is a driven roller frame. An adjustable roller rack includes a roller rack base 1, a roller 2 and a motor reduction drive. The two ends of the roller rack base 1 are respectively hinged with a roller support 3 and a roller rack hydraulic jack 5. The roller support 3 is a triangular hinged structure, and the roller rack hydraulic The jack 5 is hinged to the roller s...
