Description

Technical Field

[0001] This utility model relates to the field of roller frame technology, specifically a roller frame for welding large-diameter steel pipes. Background Technology

[0002] Roller frames, as a highly efficient and crucial welding auxiliary device, primarily drive the workpiece to rotate through the frictional force between the active rollers and the workpiece. This greatly promotes the automation and efficiency of assembly and welding operations for cylindrical structural components such as pipes, containers, and large steel pipes. Their application is particularly widespread in the welding of large-diameter steel pipes.

[0003] Currently, in the existing technology for welding large-diameter steel pipes, it is difficult to place the large-diameter steel pipes on the roller frame due to their heavy weight, and it is also difficult to remove them after welding. In view of this, a roller frame for welding large-diameter steel pipes is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a roller frame for welding large-diameter steel pipes, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a roller frame for welding large-diameter steel pipes, comprising a base, a trapezoidal block fixedly connected to a groove on the upper side of the base, a roller mechanism for supporting the large-diameter steel pipe provided on the base, and an inclined block fixedly connected to the outer wall of the base. The roller mechanism includes:

[0006] A bidirectional screw is rotatably connected to an upper groove in the base. A motor is fixedly connected to the outer wall of the base, and the output shaft of the motor is fixedly connected to the bidirectional screw.

[0007] A threaded block is threadedly connected to a bidirectional screw. The threaded block is penetrated by a guide rod and slidably connected to the guide rod. Both ends of the guide rod are fixedly connected to the upper groove of the base.

[0008] The support assembly is mounted on a threaded block. The rotation of the motor's output shaft drives the bidirectional screw to rotate, which in turn moves the threaded block, allowing the support assembly to move.

[0009] Preferably, the support assembly includes a mounting block, a rotating roller is rotatably connected to the mounting block, a reinforcing member and a crossbar are fixedly connected to the outer wall of the mounting block, and a support wheel is rotatably connected to the crossbar.

[0010] Preferably, the horizontal bar is rotatably connected to a vertical bar, and a clamping bolt is threaded onto the horizontal bar. By rotating the clamping bolt, the position of the vertical bar can be adjusted. A second support wheel is rotatably connected to the vertical bar. During the movement of the support assembly toward the large-diameter steel pipe, the support assembly gradually rises under the action of the trapezoidal block. The first and second support wheels lift and position the large-diameter steel pipe, facilitating subsequent welding operations. At the same time, the position of the vertical bar can be adjusted by using the clamping bolt, thereby adjusting the second support wheel for different pipe diameters, so that the second support wheel can stably fit against the outer wall of the steel pipe.

[0011] Preferably, a groove is formed on the outer wall of the mounting block.

[0012] Preferably, a guide rail is fixedly connected to the outer wall of the threaded block, and the guide rail slides in relation to the slide groove. By using the guide rail and the slide groove, the mounting block can remain stable during the upward process.

[0013] Preferably, the roller mechanism is provided in two sets, and the two sets of roller mechanisms are symmetrically arranged with the center line of the base as the axis of symmetry.

[0014] Preferably, the upper side of the base is provided with a placement groove. The use of the inclined block facilitates the loading and unloading of steel pipes. At the same time, the placement groove can achieve the center positioning of the steel pipes, so that the loading and unloading of steel pipes will not be obstructed after the support component is lowered.

[0015] This utility model provides a roller frame for welding large-diameter steel pipes. It has the following beneficial effects:

[0016] (1) The roller frame for welding large-diameter steel pipes is designed with inclined blocks and grooves, which allows the steel pipes to be easily put in and taken out. The grooves not only help to center the steel pipes, but also allow the support components of the roller mechanism to gradually descend after the support for the large-diameter steel pipes is released, without hindering the loading and unloading process of the steel pipes, thus simplifying the operation process and improving work efficiency.

[0017] (2) The roller frame for welding large-diameter steel pipes is driven by a motor to rotate a bidirectional screw, which in turn moves the threaded block and support assembly, thus realizing flexible support and adjustment of the large-diameter steel pipe. The support wheel one and support wheel two in the support assembly can gradually rise under the action of the trapezoidal block to lift and position the steel pipe, which is convenient for subsequent welding operations. At the same time, by adjusting the clamping bolt, the position of support wheel two can be adjusted for steel pipes of different diameters to ensure stable support of the steel pipe and improve the accuracy and efficiency of welding.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model proposes a roller frame for welding large-diameter steel pipes, including a base 1, a trapezoidal block 2 fixedly connected in the upper groove of the base 1, a roller mechanism 3 for supporting the large-diameter steel pipe on the base 1, and an inclined block 4 fixedly connected to the outer wall of the base 1.

[0029] In this embodiment of the utility model, in order to place large-diameter steel pipes, a placement groove 101 is provided on the upper side of the base 1. During the placement of large-diameter steel pipes, the large-diameter steel pipes are pushed from the inclined block 4 onto the base 1, and then the placement groove 101 is used to position the large-diameter steel pipes. During this process, the roller mechanism 3 will not obstruct the steel pipes, thus improving work efficiency.

[0030] Furthermore, the roller mechanism 3 includes a bidirectional screw 31, a threaded block 32, and a support assembly 35. The bidirectional screw 31 is rotatably connected to the upper groove of the base 1. A motor 33 is fixedly connected to the outer wall of the base 1, and the output shaft of the motor 33 is fixedly connected to the bidirectional screw 31. The threaded block 32 is threadedly connected to the bidirectional screw 31. The threaded block 32 is penetrated by a guide rod 34 and slidably connected to the guide rod 34. Both ends of the guide rod 34 are fixedly connected to the upper groove of the base 1. The support assembly 35 is set on the threaded block 32. The rotation of the output shaft of the motor 33 drives the bidirectional screw 31 to rotate, thereby driving the threaded block 32 to move, so that the support assembly 35 can be moved to facilitate subsequent support of large-diameter steel pipes.

[0031] Furthermore, the roller mechanism 3 is provided in two sets, and the two sets of roller mechanisms 3 are symmetrically arranged about the center line of the base 1. The support assembly 35 includes a mounting block 351, a rotating roller 352 rotatably connected to the mounting block 351, a reinforcing member 353 and a crossbar 354 fixedly connected to the outer wall of the mounting block 351, a support wheel 355 rotatably connected to the crossbar 354, a vertical rod 356 rotatably connected to the crossbar 354, and a clamping bolt 357 threadedly connected to the crossbar 354. By rotating the clamping bolt 357, the position of the vertical rod 356 can be adjusted. A second support wheel 358 rotatably connected to the vertical rod 356. A groove 3511 is provided on the wall, and a guide rail 321 is fixedly connected to the outer wall of the threaded block 32. The guide rail 321 slides with the groove 3511. The support assembly 35 moves towards the large-diameter steel pipe, and the rotating roller 352 rolls onto the trapezoidal block 2, causing the mounting block 351 to gradually rise under the action of the guide rail 321. This causes the first support wheel 355 and the second support wheel 358 to gradually rise, thereby lifting and positioning the steel pipe, which facilitates subsequent welding operations. At the same time, by adjusting the clamping bolt 357, the position of the second support wheel 358 can be adjusted for steel pipes of different diameters to ensure stable support of the steel pipe and improve the accuracy and efficiency of welding.

[0032] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0033] In use, the large-diameter steel pipe is first pushed from the inclined block 4 onto the base 1. Then, the large-diameter steel pipe is positioned by placing the groove 101. The motor 33 is then started, and the output shaft of the motor 33 rotates, driving the bidirectional screw 31 to rotate, which in turn drives the threaded block 32 to move, so that the support assembly 35 can be moved. As the support assembly 35 moves toward the large-diameter steel pipe, the rotating roller 352 rolls onto the trapezoidal block 2, causing the mounting block 351 to gradually rise under the action of the guide rail 321. This causes the first support wheel 355 and the second support wheel 358 to gradually rise, thus lifting and positioning the steel pipe, which facilitates subsequent welding operations. At the same time, by adjusting the clamping bolt 357, the position of the second support wheel 358 can be adjusted for steel pipes of different diameters to ensure stable support of the steel pipe.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
