Abstract
Description
Technical Field
[0001] The utility model relates to the field of straightening processing equipment, in particular to a gantry movable steel pipe straightening machine. Background Art
[0002] Before industrial applications, steel pipes need to be straightened to prevent bending. A steel pipe straightener is a device specifically designed for straightening steel pipes. Depending on how the straightening position is adjusted, steel pipe straighteners are categorized as either gantry-type (mobile) or fixed-gantry (where a supporting structure drives the pipe).
[0003] Common gantry movable square tube straightening machines are mostly steel tube straightening and pipe mouth rounding devices disclosed in the patent with publication number CN217595564U, in which the gantry moves back and forth on the laid track through the running part at the bottom. At present, during the correction process of the steel tube straightening machine, the gantry is prone to lateral movement due to the fact that the bent part of the steel tube easily provides lateral thrust to the gantry. Based on this, some existing products adopt the method of setting a brake structure (holding stop) on the running wheel of the running part. During application, the applicant found that since the running wheels mostly use relatively smooth steel parts, when the straightening is pressed down, the vertical force of the gantry on the running wheels is reduced, resulting in a further reduction in the friction between the gantry and the track, so its braking effect is limited. Based on this, the applicant proposed a gantry movable steel tube straightening machine. Utility Model Content

[0021] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0022] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0023] In this utility model, if Figures 1 to 3 As shown, a gantry movable steel pipe straightening machine is provided, comprising a T-shaped track 1 laid on the ground and a gantry 2 on the upper side of the track, the gantry 2 including a walking part 3, and the walking part 3 is provided with two groups of walking wheels 4 at intervals along the extension direction of the T-shaped track; the straightening machine also includes a locking assembly arranged between the two groups of walking wheels 4, and the locking assembly includes a first locking wheel 5 and a second locking wheel 6 arranged on the lower side of the T-shaped track, the first locking wheel 5 and the second locking wheel 6 are both configured as cams, and the cam portion 7 of the first locking wheel 5 and the second tightening wheel can be switched from rotating to a limited state in which it is pressed upward against the transverse surface of the T-shaped track, to a released state in which the cam portion 7 is separated from the transverse surface of the T-shaped track; the straightening machine also includes a driving assembly that drives the first locking wheel 5 and the second locking wheel 6 to rotate in opposite directions; wherein, when the first locking wheel 5 and the second locking wheel 6 are in the released state, the first locking wheel 5 and the second locking wheel 6 can rotate in opposite directions to a limited state.
[0024] When the steel pipe straightening machine of the present invention is in use, when straightening operations are required, the driving assembly drives the first locking wheel 5 and the second locking wheel 6 to rotate, so that the cam portion 7 abuts against the transverse surface of the T-track 1 to stop the walking portion 3 from moving laterally. During the straightening process, the pressing force between the cam portion 7 and the transverse surface of the T-track 1 is not easily affected by the downward pressure and becomes smaller (even if it is affected, it tends to further press the cam portion 7 against the transverse surface), and the stopping effect can be maintained. When the position of the gantry 2 needs to be adjusted, the first locking wheel 5 and the second locking wheel 6 can be driven to rotate by the driving assembly to separate the cam portion 7 from the transverse surface of the T-track 1.

[0026] As shown in the figure, by arranging the first locking wheel 5 and the second locking wheel 6 in a locking wheel group, and driving the two rack parts 901 of a driving rack 9 to rotate synchronously, the two cam parts 7 of the same locking wheel group can resist each other's lateral force on the track during the locking process, so as to prevent the gantry 2 from moving laterally during the dynamic locking process of the cam rotating part 7.
[0027] In the illustrated embodiment, with respect to the structure of the present invention, to be more specific, the driving rack 9 includes a transverse rib 902 connecting two rack portions 901 .
