Description

Technical Field

[0001] This utility model belongs to the field of circular tube cutting technology, specifically relating to a circular tube horizontal adjustment device. Background Technology

[0002] In steel pipe towers, the steel pipes are the core components of the vertical support, bearing the main load-bearing role. Therefore, their verticality requirements are extremely high, and their manufacturing precision is also strictly controlled. In the current steel pipe tower manufacturing process, the steel pipes are mainly processed by first leveling each pipe individually, then marking vertical lines on the steel pipes, and finally using these as a basis for cutting the circular pipe sections.

[0003] However, due to the large number of steel pipes and the potential errors caused by manual operation, the vertical accuracy of the cut surface of the round pipes is difficult to meet the established standards. Furthermore, since each round pipe needs to go through a series of tedious steps such as leveling and scribing, it not only significantly increases the manufacturing cost but also extends the production cycle, thus having a significant negative impact on the overall efficiency of the factory. Utility Model Content

[0004] The purpose of this invention is to provide a horizontal adjustment device for a circular tube, which solves the technical problems of low vertical accuracy of the circular tube cutting surface and complex operation in the prior art.

[0009] The mounting bracket can be detachably installed on the end of the round tube;

[0010] The rotating wheel is rotatably mounted on the fixed frame.

[0011] This application uses an adjustable roller frame to level the round tube, and then sets a reference plate at one end of the round tube. The rotating wheel rotates along the reference plate through a detachable mounting bracket, thereby achieving the function of levelness detection. This improves the vertical accuracy of the cutting surface and has the advantages of simple structure, convenient operation, high work efficiency and low labor cost, thus greatly reducing manufacturing costs and shortening the production cycle.

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0044] First, it should be noted that some directional terms used in the following description to clearly illustrate the technical solution of this utility model, such as the terms "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," are all derived from the normal orientation of the components in the circular tube horizontal adjustment device. They are only used to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0047] Example:

[0048] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown in the figure, this application discloses a circular tube horizontal adjustment device for achieving precise adjustment of the verticality of the circular tube cross section. Its specific structure includes: a base plate 1, a reference plate 2, multiple adjustable roller frames 3, a fixed frame 4, and a rotating wheel 5.

[0049] The base plate 1 is arranged horizontally, serving as the foundation support surface for the entire device.

[0050] The reference plate 2 is vertically installed on the top surface of the base plate 1. It serves as a reference standard for measuring and adjusting the verticality of the circular tube, ensuring that the circular tube meets the required verticality.

[0051] Multiple adjustable roller frames 3 are arranged side by side and located on one side of the reference plate 2, and are spaced apart on the top surface of the base plate 1. They are used to support and rotate the circular tube and can be adjusted in height as needed.

[0052] The fixing bracket 4 can be detachably installed on the end of the round tube and can stably follow the round tube to rotate circumferentially, ensuring the accuracy and reliability of the adjustment.

[0053] The rotating wheel 5 is mounted on the fixed frame 4 and is used to roll against the reference plate 2 to perform verticality detection.

[0054] The above technical solution is used as follows:

[0055] First, the fixing frame 4 is installed on the non-cut end of the round tube. Then, the round tube is placed horizontally on multiple adjustable roller frames 3 using a lifting device, and the rotating wheel 5 is brought into contact with the reference plate 2. Next, the round tube is driven to rotate circumferentially by the adjustable roller frames 3, causing the rotating wheel 5 to move along with it. If the rotating wheel 5 disengages from the reference plate 2 during one rotation, the height of one end of the round tube can be adjusted using the adjustable roller frames 3 until it is in close contact again, thus achieving a leveling effect. When the rotating wheel 5 remains in close contact with the reference plate 2 throughout one rotation, it indicates that the steel tube is now horizontal. The steel tube is then allowed to continue rotating circumferentially, and the end of the round tube to be cut is cut using a flame cutting device. This avoids scribing on individual round tubes and ensures high vertical accuracy of the cut surface.

[0056] This invention uses an adjustable roller frame 3 to level the round tube, and a reference plate 2 is set at one end of the round tube. The rotating wheel 5 rotates along the reference plate 2 through a detachable mounting bracket 4, thereby achieving the function of levelness detection. This improves the vertical accuracy of the cutting surface and has the advantages of simple structure, convenient operation, high work efficiency and low labor cost, thus greatly reducing manufacturing costs and shortening the production cycle.

[0057] In some embodiments, as Figure 3 and Figure 5As shown, the fixing frame 4 includes: a U-shaped block 41, a support plate 42, a locking bolt 43, and two support bars 44; specifically, the U-shaped block 41 has a slot 411 on one side; the support plate 42 is located at the open end of the U-shaped block 41; the locking bolt 43 is threaded onto the support plate 42; the two support bars 44 are respectively located on both sides of the U-shaped block 41; wherein, the rotating wheel 5 is rotatably connected between the two support bars 44 and is located on the side of the U-shaped block 41 away from the opening.

[0058] In use, the U-shaped block 41 engages with the end face of the round tube through the slot 411, and then the locking bolt 43 is tightened. The locking bolt 43 gradually passes through the support plate 42 until it is in close contact with the outer wall of the round tube. At this time, the fixing bracket 4 is firmly installed on the end face of the round tube and the rotating wheel 5 is supported by the support bar 44, so that it can be stably attached to the reference plate 2 and roll.

[0059] The design of the fixing bracket 4 described above improves the installation stability, ensures the adjustment effect, and facilitates disassembly and assembly, thereby improving work efficiency. In addition, the structure is simple and reduces production and manufacturing costs.

[0060] In some embodiments, as Figure 5 As shown, the two side walls of the slot 411 are gradually inclined inward in a V-shape, which can be used for round tubes of different thicknesses, improving the applicability of the fixing frame 4 and enhancing the effect of the device.

[0061] In some embodiments, as Figure 5 As shown, it also includes: a displacement adjustment mechanism 6, which is installed on the top surface of the base plate 1 and has a drive end connected to the reference plate 2 for driving the reference plate 2 to approach or move away from the end face of the circular tube.

[0062] By setting the displacement adjustment mechanism 6, the reference plate 2 can be easily driven to approach or move away from the end face of the round tube, which facilitates its contact with the rotating wheel 5, thereby improving the ease of operation, increasing the leveling efficiency, and shortening the manufacturing cycle.

[0063] Based on the above embodiments, such as Figure 2 As shown, the displacement adjustment mechanism 6 includes: a mounting plate 61, multiple linear guide rails 62, multiple linear bearings 63, and multiple locking structures 64, configured as follows:

[0064] The mounting plate 61 is arranged horizontally and is located at the bottom of the reference plate 2;

[0065] Multiple linear guides 62 are arranged side by side at intervals and installed on the top surface of the base plate 1;

[0066] Multiple linear bearings 63 are slidably connected to the linear guide rail 62 in a one-to-one correspondence and are located at the bottom of the mounting plate 61;

[0067] Multiple locking structures 64 are installed one-to-one on the linear bearing 63, which can lock and fix the linear axis and the linear guide rail 62.

[0068] For example, two linear guide rails 62, linear bearings 63 and locking structures 64 are provided, which support the mounting plate 61 at both ends. This method has low manufacturing cost and high support stability.

[0069] In use, the mounting plate 61 is pushed and pulled, which drives each linear bearing 63 to move and slide on the corresponding linear guide rail 62. After the reference plate 2 moves to the appropriate position, the linear bearing 63 is locked to the corresponding linear guide rail 62 by the locking structure 64, thereby fixing the reference plate 2.

[0070] The design of the displacement adjustment mechanism 6 described above ensures the verticality of the reference plate 2, improves the smoothness of movement and the stability of fixation, and has a simple and compact structure that is easy to install and arrange.

[0071] Based on the above embodiments, such as Figure 2 As shown, the locking structure 64 includes a threaded rod 641 and an adjusting wheel 642; wherein, one end of the threaded rod 641 passes through the linear bearing 63 and is threadedly engaged with the linear bearing 63, and can abut against the linear guide rail 62; the adjusting wheel 642 is fixedly fitted onto the other end of the threaded rod 641.

[0072] In use, the operator can easily drive the threaded rod 641 to rotate by rotating the adjusting wheel 642, so that it is screwed into the linear bearing 63 and tightly abuts against the linear guide rail 62, thereby achieving a locking function.

[0073] The above design improves the ease of operation for workers, ensures the flexibility of the locking position, and has a simple structure that is easy to manufacture.
