It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification.

[0027] In current production, the conventional roller tire rack 100 is a fixed structure. After each three-dimensional segment is manufactured, the roller tire rack 100 must be modified to adapt to the manufacturing of the next segment. Such repeated modifications cause irreparable damage to the roller tire rack 100 each time, which means that a large amount of manpower and material resources are invested in the tire rack modification work, and the service life of the roller tire rack 100 is reduced.

[0028] The existing roller tire rack 100 relies on a crane to adjust the horizontal position and vertical height to achieve positioning, and the lifting process requires manual adjustment of the distance. Only after repeated adjustments and positioning can the process requirements be met. The entire construction process consumes a lot of time, and there are unpredictable safety hazards during the construction process.

[0029] To this end, the present application proposes a roller tire rack 100 .

[0030] like Figure 1 As shown, the roller tire rack 100 according to the embodiment of the present application includes: a support frame 10 and a rail vehicle 30.

[0031] A roller assembly 20 for limiting the position of the workpiece 200 to be processed is provided on the support frame 10. The support frame 10 is connected to the body of the rail vehicle 30 and is located above the rail vehicle 30. The rail vehicle 30 is used to drive the support frame 10 to move in a horizontal plane; wherein, a lifting device 40 is provided between the rail vehicle 30 and the support frame 10, and the lifting device 40 is configured to drive the support frame 10 to rise or fall in a vertical direction.

[0032] It is understandable that the workpiece 200 to be processed can be segmented into a cylindrical or conical shape, etc., which is not limited here.

[0033] For example Figure 1 As shown, when the roller tire rack 100 positions the workpiece 200 to be processed, two roller tire racks 100 may be provided, and the two roller tire racks 100 are spaced apart and distributed in the length direction of the workpiece 200 to be processed, so as to limit the axial ends of the workpiece 200 to be processed through the corresponding roller assemblies 20 of the two roller tire racks 100, thereby realizing the positioning of the workpiece 200 to be processed.

[0034] In order to adapt to the axial length of the workpiece 200 to be processed, the roller tire frame 100 needs to be moved horizontally. In the related art, the roller tire frame 100 is lifted by a crane to achieve horizontal movement of the roller tire frame 100. In the present application, a rail car 30 is provided to facilitate the support frame 10 and the roller assembly 20 to move in the horizontal plane through the rail car 30, thereby achieving the adjustment of the horizontal position of the roller tire frame 100.

[0035] It can be understood that the rail vehicle 30 generally includes a vehicle body and wheels 31, and the rail vehicle 30 refers to a liftable rail vehicle 30 that is similar to a slipway trolley and can be raised and lowered, moved forward and backward.

[0036] Furthermore, when the workpiece 200 to be processed is a conical structure, in order to ensure that the axial ends of the conical structure can be at the same horizontal height, it is necessary to adjust the vertical height of a roller tire rack 100 so that the upper surface of the conical structure remains horizontal. In the present application, a lifting device 40 is provided, and the lifting device 40 can drive the support frame 10 to drive the roller assembly 20 to rise or fall in the vertical direction to achieve the adjustment of the vertical position of the roller tire rack 100. In this way, it is easy to reduce the difficulty of positioning the roller tire rack 100, which is beneficial to improving the positioning efficiency of the roller tire rack 100 and reducing safety risks.

[0037] According to the roller tire rack 100 of the embodiment of the present application, a rail car 30 is provided to install the support frame 10 and the roller assembly 20 on the rail car 30. In this way, the support frame 10 and the roller assembly 20 can be driven by the rail car 30 to move in the horizontal plane to adjust the horizontal position of the roller tire rack 100, and the lifting device 40 can drive the support frame 10 to drive the roller assembly 20 to rise or fall in the vertical direction to adjust the vertical position of the roller tire rack 100. In this way, it is easy to reduce the difficulty of positioning the roller tire rack 100, which is beneficial to improving the positioning efficiency of the roller tire rack 100 and reducing safety risks.

[0038] In some embodiments, Figure 2 As shown, the roller assembly 20 includes a first roller 21 and a second roller 22 , and the first roller 21 and the second roller 22 are spaced apart in a horizontal direction.

[0039] Thus, the workpiece 200 can be placed between the first roller 21 and the second roller 22 , so that the first roller 21 and the second roller 22 can limit the workpiece 200 on both sides of the workpiece 200 , thereby achieving the limitation of the workpiece 200 .

[0040] In some embodiments, Figure 2 As shown, a first roller frame 24 and a second roller frame 25 are provided on the support frame 10 , the first roller 21 is rotatably mounted on the first roller frame 24 , and the second roller 22 is rotatably mounted on the second roller frame 25 .

[0041] Therefore, by setting the first roller frame 24 and the second roller frame 25, the first roller 21 can be rotatably mounted on the first roller frame 24, and the second roller 22 can be rotatably mounted on the second roller frame 25. In this way, when the workpiece 200 to be processed is placed between the first roller 21 and the second roller 22, the workpiece 200 to be processed can roll and rub against the first roller 21 and the second roller 22, so as to play an auxiliary role when the workpiece 200 to be processed is placed between the first roller 21 and the second roller 22.

[0042] In some embodiments, the first roller frame 24 and the second roller frame 25 are both slidably connected to the support frame 10, and as shown in FIG. Figure 2 As shown, the roller assembly 20 further includes an adjusting member 23, and the adjusting member 23 is used to drive the first roller frame 24 and the second roller frame 25 to move toward or away from each other.

[0043] Therefore, the distance between the first roller frame 24 and the second roller frame 25 can be adjusted by the adjusting member 23, thereby adjusting the distance between the first roller 21 and the second roller 22, so that the roller frame 100 can position the workpieces 200 with different diameters.

[0044] For example, the adjusting member 23 is used to drive the first roller frame 24 and the second roller frame 25 to move toward each other so as to reduce the distance between the first roller frame 24 and the second roller frame 25, that is, to reduce the distance between the first roller 21 and the second roller 22, so that the first roller 21 and the second roller 22 can play a limiting role on the workpiece 200 with a smaller diameter.

[0045] Alternatively, the adjusting member 23 is used to drive the first roller frame 24 and the second roller frame 25 to move in a direction away from each other to increase the distance between the first roller frame 24 and the second roller frame 25, that is, to increase the distance between the first roller 21 and the second roller 22, so that the first roller 21 and the second roller 22 can limit the workpiece 200 with a larger diameter.

[0046] In some implementations, the adjustment member 23 may be a ball screw structure, or an electric telescopic rod structure, etc., which is not limited here.

[0047] In some embodiments, Figure 2 As shown, a first stopper 51 and a second stopper 52 are provided on the support frame 10. The first stopper 51 is located on the side of the first roller frame 24 away from the second roller frame 25 and is used to stop the first roller frame 24. The second stopper 52 is located on the side of the second roller frame 25 away from the first roller frame 24 and is used to stop the second roller frame 25.

[0048] Therefore, by providing the first stopper 51 , the first roller frame 24 can abut against the first stopper 51 after moving a certain distance in a direction away from the second roller frame 25 , thereby preventing the first roller frame 24 from excessively moving.

[0049] At the same time, by providing the second stopper 52 , the second roller frame 25 can abut against the second stopper 52 after moving a certain distance in a direction away from the first roller frame 24 , thereby preventing the second roller frame 25 from excessively moving.

[0050] In some embodiments, the first stopper 51 and / or the second stopper 52 are configured as flexible members.

[0051] For example, the first stop member 51 is constructed as a flexible member, so that when the first stop member 51 abuts against the first roller frame 24, rigid contact between the first stop member 51 and the first roller frame 24 can be avoided, thereby reducing damage to the first stop member 51 and the first roller frame 24, which is beneficial to protecting the first stop member 51 and the first roller frame 24.

[0052] Alternatively, the second stop member 52 is constructed as a flexible member, so that when the second stop member 52 abuts against the second roller frame 25, rigid contact between the second stop member 52 and the second roller frame 25 can be avoided, thereby reducing damage to the second stop member 52 and the second roller frame 25, which is beneficial to protecting the second stop member 52 and the second roller frame 25.

[0053] Alternatively, the first stopper 51 and the second stopper 52 are both constructed as flexible members, so that when the first stopper 51 abuts against the first roller frame 24, the first stopper 51 and the first roller frame 24 can be prevented from being in rigid contact, thereby reducing damage to the first stopper 51 and the first roller frame 24, which is beneficial to protecting the first stopper 51 and the first roller frame 24. When the second stopper 52 abuts against the second roller frame 25, the second stopper 52 and the second roller frame 25 can be prevented from being in rigid contact, thereby reducing damage to the second stopper 52 and the second roller frame 25, which is beneficial to protecting the second stopper 52 and the second roller frame 25.

[0054] In some embodiments, the first stopper 51 and / or the second stopper 52 include bolts.

[0055] For example, the first stop member 51 includes a bolt, which can be inserted into the support frame 10, and a nut can be provided on the part of the bolt extending above the support frame 10. In this way, the bolt and the nut can play a role in stopping the first roller frame 24, and the setting method of the bolt and the nut is relatively simple, which is conducive to reducing the setting cost.

[0056] Alternatively, the second stop member 52 includes a bolt, which can be inserted into the support frame 10, and a nut can be provided at the portion of the bolt extending above the support frame 10. In this way, the bolt and the nut can play a role in stopping the second roller frame 25, and the arrangement of the bolt and the nut is relatively simple, which is conducive to reducing the arrangement cost.

[0057] Alternatively, the first stopper 51 and the second stopper 52 are both constructed as bolts, and can achieve the same technical effect as above, which will not be repeated here.

[0058] In some embodiments, the support frame 10 is provided with a slide groove (not shown in the figure), and the first roller frame 24 and the second roller frame 25 are respectively provided with a sliding protrusion (not shown in the figure), and the sliding protrusion is slidably matched with the slide groove.

[0059] Therefore, by providing a sliding groove on the support frame 10, the first roller frame 24 and the second roller frame 25 are respectively provided with sliding protrusions, so as to enhance the stability of the sliding cooperation between the first roller frame 24 and the second roller frame 25 and the support frame 10 respectively, and the setting of the sliding groove can play a certain guiding role in the sliding of the first roller frame 24 and the second roller frame 25.

[0060] In some implementations, rollers are further provided at the bottom of the slide groove, so that when the first roller frame 24 and the second roller frame 25 slide, the sliding friction can be converted into rolling friction through the rollers, thereby reducing the friction force to improve the sliding efficiency.

[0061] In some embodiments, the adjustment member 23 includes a hydraulic system.

[0062] Therefore, the distance between the first roller frame 24 and the second roller frame 25 can be controlled by the hydraulic system, that is, the distance between the first roller 21 and the second roller 22 can be controlled, and the control of the hydraulic system can make the adjustment of the distance between the first roller 21 and the second roller 22 more precise, which is conducive to improving the control accuracy.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the support frame 10 is detachably connected to the lifting device 40 via a connecting flange 60 .

[0064] Therefore, by providing the connecting flange 60 , the difficulty of connecting the support frame 10 and the lifting device 40 can be reduced, and the structure of the connecting flange 60 is relatively simple, which is conducive to reducing costs.

[0065] In some embodiments, Figure 1 As shown, the roller tire rack 100 further includes a controller 70 , which is mounted on the rail vehicle 30 and electrically connected to the lifting device 40 .

[0066] Therefore, by providing the controller 70, the working state of the lifting device 40 can be controlled by the controller 70, so that the automatic control of the roller tire rack 100 can be realized, which helps to reduce the control difficulty.

[0067] Compared with the prior art, the roller tire rack 100 of the present application has at least the following advantages: the use of the roller tire rack 100 for construction not only saves the need for lifting, driving and other supporting construction operations, but also eliminates various safety risk factors in the lifting process. No iron shims are required for bow and stern level adjustment, thus avoiding the possibility of iron sheets flying out and injuring people, as well as damage to the roller and the workpiece 200 caused by the iron sheets. When adjusting the level, there is no need to weld tooling rings on the segmented surface, thus avoiding welding tooling on the segmented surface and subsequent dismantling and grinding work.

[0068] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
