Description

Technical Field

[0001] This utility model relates to the technical field of pipe cutting devices for construction projects, specifically a circular pipe positioning structure for a pipe cutting device for construction projects. Background Technology

[0002] Construction pipe cutting equipment is a type of device used for cutting engineering pipes. Based on the power type, it can be divided into manual cutting devices, electric cutting devices, pneumatic cutting devices, and hydraulic cutting devices. Based on the cutting principle, it can be divided into mechanical sawing, grinding cutting, flame cutting, plasma cutting, and special cutting, etc. Regardless of the type of cutting device, the core structure is designed around stable clamping and precise cutting. It mainly consists of a frame, positioning structure, cutting mechanism, drive system, and control system. The positioning structure fixes the pipe with hydraulic or manual clamps to prevent slippage during cutting.

[0003] Chinese Patent Publication No. CN118875532B discloses a laser cutting device for metal pipe processing. In actual use, the compression spring of the bottom clamp is compressed under the weight of the round pipe, causing the central axis of the round pipe to shift. This results in a deviation between the axis of the round pipe and the cutting center of the cutting device, which in turn affects the perpendicularity of the cut. Moreover, the clamp is in rigid contact with the surface of the round pipe, which can easily scratch the surface of the pipe. Therefore, a round pipe positioning structure for a pipe cutting device for construction projects is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a circular pipe positioning structure for a pipe cutting device in construction engineering. It has advantages such as facilitating the centering and positioning of the circular pipe, and solves the problems of the circular pipe's central axis shifting due to the compression of the bottom clamp's telescopic spring under its own weight, resulting in a deviation between the circular pipe's axis and the cutting center of the cutting device, which in turn affects the perpendicularity of the cut. Furthermore, the rigid contact between the clamp and the circular pipe surface can easily scratch the pipe surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circular pipe positioning structure for a pipe cutting device in construction engineering, including an mounting plate disposed on the pipe cutting device, wherein a support platform is disposed on the mounting plate;

[0006] The support platform is provided with a number of positioning components for positioning round tubes, and the support platform is provided with an adjusting component for adjusting the positioning components to position round tubes of different sizes. The mounting plate is provided with a drive assembly for controlling the rotation of the adjusting component.

[0007] The positioning component includes a connecting bracket, on which a connecting shaft and a movable shaft are fixedly mounted, and on which a rubber roller for positioning and protecting the round tube is fixedly mounted.

[0008] The adjusting component includes an adjusting ring rotatably mounted inside the support platform. Three adjusting plates, each with one end penetrating the support platform, are fixedly mounted on the outer surface of the adjusting ring. The adjusting ring has several connecting holes, and the connecting holes are rotatably connected to the connecting shaft.

[0009] The support platform has several limiting grooves, and the inner wall of the limiting groove is slidably connected to the movable shaft. The support platform also has three arc-shaped grooves, and the inner wall of the arc-shaped grooves is slidably connected to the outer surface of the adjusting plate.

[0010] Furthermore, the drive assembly includes an electric push rod fixedly mounted on the mounting plate, the telescopic end of the electric push rod being fixedly connected to a connecting frame, and a pin shaft rotatably mounted on the connecting frame and connected to the adjustment plate.

[0011] Furthermore, a guide groove is provided on the adjustment plate, and one end of the pin passes through the guide groove and is slidably connected to the inner wall of the guide groove.

[0012] Furthermore, the mounting plate is provided with a number of positioning shafts for fixing and connecting the support platform. The bottom of the support platform is provided with a number of mounting holes, and one end of the positioning shaft passes through and extends into the interior of the mounting hole.

[0013] Furthermore, the number of positioning components is no less than three, and they are symmetrical about the central axis of the adjusting ring. The number of connecting holes and limiting grooves matches the number of positioning components.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The pipe positioning structure of the pipe cutting device in this construction project, through the setting of adjusting components, positioning components, and drive components, achieves the clamping and positioning of the round pipe by using no less than three rubber rollers to synchronously approach the center, thereby achieving the centering and positioning of the round pipe and ensuring that the axis of the round pipe coincides with the cutting center of the cutting device, effectively ensuring the perpendicularity of the cut. Through the linkage of the adjusting components and positioning components, the spacing of the rubber rollers can be continuously adjusted to accommodate round pipes of different diameters. The positioning components use rubber rollers to contact the round pipe. The rubber material has low hardness and moderate friction, which can not only stably clamp the round pipe, but also avoid scratching the surface of the pipe by the metal claws. The adjusting plate slides along the arc groove and the movable shaft slides along the limiting groove. The dual trajectory restriction ensures that the movement of the adjusting ring and positioning components is precise and controllable, avoiding shaking or jamming, and improving positioning stability.

Detailed Implementation

[0023] 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.

[0024] Example 1: Please refer to Figure 1-6 The circular pipe positioning structure of a construction pipe cutting device in this embodiment includes an installation plate 1 set on the pipe cutting device, a support platform 2 set on the installation plate 1, and a plurality of positioning shafts for fixing and connecting the support platform 2 on the installation plate 1. A plurality of mounting holes are opened at the bottom of the support platform 2, and one end of the positioning shaft passes through and extends into the interior of the mounting hole.

[0025] Example 2: Please refer to Figure 1-6 Based on Embodiment 1, the support platform 2 is provided with a number of positioning components 4 for positioning round tubes, the support platform 2 is provided with adjusting components 3 for adjusting the positioning components 4 to position round tubes of different sizes, and the mounting plate 1 is provided with a drive assembly 5 for controlling the rotation of the adjusting components 3.

[0026] The positioning component 4 includes a connecting bracket 41, on which a connecting shaft 42 and a movable shaft 43 are fixedly installed, and on which a rubber roller 44 for positioning and protecting the round tube is fixedly installed;

[0027] The adjusting component 3 includes an adjusting ring 31 rotatably installed inside the support platform 2. Three adjusting plates 32, each with one end penetrating through the support platform 2, are fixedly installed on the outer surface of the adjusting ring 31. The adjusting ring 31 has several connecting holes 34, and the connecting holes 34 are rotatably connected to the connecting shaft 42.

[0028] The support platform 2 has several limiting grooves 21, and the inner wall of the limiting groove 21 is slidably connected to the movable shaft 43. The support platform 2 has three arc-shaped grooves 22, and the inner wall of the arc-shaped grooves 22 is slidably connected to the outer surface of the adjusting plate 32.

[0029] The number of positioning components 4 is no less than three, and they are symmetrical about the center of the central axis of the adjusting ring 31. The number of connecting holes 34 and limiting grooves 21 matches the number of positioning components 4. The rubber rollers 44 in the positioning components 4 contact the round tube to avoid damage to the surface of the round tube during positioning. When multiple rubber rollers 44 approach the center at the same time, they can clamp the round tube to achieve centering and positioning.

[0030] Using the above technical solution, the connecting hole 34 on the adjusting ring 31 is rotatably connected to the connecting shaft 42 of the positioning member 4. When the adjusting ring 31 rotates, it pulls or pushes the connecting shaft 42 through the connecting hole 34. At the same time, the movable shaft 43 of the positioning member 4 slides along the limiting groove 21 of the support platform 2, and the limiting groove 21 restricts the movement direction of the movable shaft 43. The two work together to make the positioning member 4 swing around the line connecting the connecting shaft 42 and the movable shaft 43, which ultimately drives the rubber roller 44 on the positioning member 4 to gather towards the center or open outward. Since the positioning member 4 is symmetrically distributed around the central axis of the adjusting ring 31, the rubber roller 44 can clamp the round tube when it approaches the center to achieve centering and positioning, and can release the round tube when it opens, thus facilitating continuous round tube cutting.

[0031] Example 3: Please refer to Figure 1-6 Based on Embodiment 2, the drive assembly 5 includes an electric push rod 51 fixedly installed on the mounting plate 1. The telescopic end of the electric push rod 51 is fixedly connected to a connecting frame 52, and a pin 53 connected to the adjusting plate 32 is rotatably installed on the connecting frame 52.

[0032] The adjusting plate 32 has a guide groove 33. One end of the pin 53 passes through the guide groove 33 and is slidably connected to the inner wall of the guide groove 33. The connecting frame 52 is controlled by the electric push rod 51 and the pin 53 is driven to make linear movement, thereby controlling the pin 53 to slide in the guide groove 33, and thus driving the adjusting plate 32 to slide along the arc groove 22.

[0033] Using the above technical solution, the electric push rod 51 in the drive assembly 5 serves as the power source. Its telescopic end drives the pin 53 to move linearly through the connecting frame 52. The pin 53 is embedded in the guide groove 33 of the adjustment plate 32. When the pin 53 moves, it pushes the adjustment plate 32 to slide along the arc groove 22 of the support platform 2, thereby using the arc groove 22 to limit the movement trajectory of the adjustment plate 32, and thus driving the adjustment ring 31 to rotate around its own axis.

[0034] The working principle of the above embodiments is as follows:

[0035] In the construction project pipe cutting device, the round pipe positioning structure uses the electric push rod 51 in the drive assembly 5 as a power source. Its telescopic end drives the pin 53 to move linearly through the connecting frame 52. The pin 53 is embedded in the guide groove 33 of the adjusting plate 32. When the pin 53 moves, it pushes the adjusting plate 32 to slide along the arc groove 22 of the support platform 2, thereby using the arc groove 22 to limit the movement trajectory of the adjusting plate 32, and then driving the adjusting ring 31 to rotate around its own axis.

[0036] The connecting hole 34 on the adjusting ring 31 is rotatably connected to the connecting shaft 42 of the positioning member 4. When the adjusting ring 31 rotates, it pulls or pushes the connecting shaft 42 through the connecting hole 34. At the same time, the movable shaft 43 of the positioning member 4 slides along the limiting groove 21 of the support platform 2 and uses the limiting groove 21 to restrict the movement direction of the movable shaft 43. The two work together to make the positioning member 4 swing around the line connecting the connecting shaft 42 and the movable shaft 43, and finally drive the rubber roller 44 on the positioning member 4 to gather towards the center or open outward.

[0037] Since the positioning element 4 is symmetrically distributed around the center of the adjusting ring 31, the rubber roller 44 can clamp the round tube when it approaches the center, thus achieving centering and positioning. When it opens, it can release the round tube, which facilitates continuous round tube cutting.
