During cutting, the rotating top support rod provides support to the inner wall of the pipe, preventing deformation of the pipe opening due to external cutting forces.

Description

Technical Field

[0001] This utility model relates to the technical field of pipe cutting equipment, specifically a pipe cutting device for water conservancy construction. Background Technology

[0002] The selection of pipe materials for water conservancy projects should be based on specific working conditions, such as pressure, medium properties, burial depth, and cost-effectiveness. For example, in coastal areas, seawater corrosion should be a primary consideration, and FRP or stainless steel pipes should be selected. For farmland irrigation, economical PE pipes can be given priority. In the future, the application of composite materials and environmentally friendly materials will further enhance the sustainability of water conservancy projects.

[0003] Currently, various materials are used for pipes in water conservancy construction. Among them, large-diameter PE pipes have high wall thickness and hardness. During the cutting process, due to the hollow state inside the pipe, greater external force is required, which further aggravates the risk of deformation and easily leads to irregular deformation of the pipe opening. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a pipe cutting device for water conservancy construction. When cutting the pipe, an extension support is nested into the pipe to be cut, so that a rotating top support rod of the same diameter as the pipe can be used to support the inner wall of the pipe. Thus, during cutting, the rotating top support rod generates support force, preventing the pipe from deforming due to external force during cutting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe cutting device for hydraulic construction, comprising an equipment support platform, a pipe internal support device fixed above the equipment support platform, a cutting assembly installed behind the equipment support platform, and a pipe feeding platform below the cutting assembly; a rotating seat is provided inside the pipe internal support device, a ball-head rotating rod is installed on the rotating seat, a tension rod is connected to the ball-head rotating rod, a connecting support rod is connected to the end of the tension rod, and an even number of extension supports are installed on the connecting support rod. The extension supports are mainly used to adapt to the inner wall of the pipe for support, so that during cutting, the extension supports press against the inner wall of the pipe, preventing deformation of the pipe cut caused by pressure on the cutter during the cutting process.

[0006] Furthermore, an even number of fixing slots are provided on each of the even-numbered expansion supports, and each fixing slot is equipped with a threaded locking block. Each threaded locking block has a locking pin fixed to its surface, and a rotating top support rod is threaded onto each threaded locking block. The rotating top support rod is mainly used to match pipes of different diameters, allowing for simultaneous adaptation and replacement as the diameter of the pipes used in hydraulic construction changes.

[0007] Furthermore, the rotating top support rod can be replaced according to the pipe diameter. The locking pin is used to fix the threaded locking block in the fixing groove. The extension support is embedded in the connecting support rod. The rotating seat is fixed to the equipment support platform. The ball-head rotating rod can be adjusted in angle with the rotating seat. The pipe auxiliary feeding table is installed on the equipment support platform and slides with it. The ball-head rotating rod is mainly used to rotate in conjunction with the rotating seat, and then adjusts laterally with the tension rod to allow the connecting support rod to complete angle adjustment and cooperate with the pipe.

[0008] Furthermore, the pipe fitting delivery platform includes a platform body with an even number of inner clamps fixed to its surface. An even number of connecting clamps are mounted on the upper surface of each inner clamp. A replaceable pipe support platform is connected to each inner clamp, and an even number of pipe fitting pressure clamps are positioned above the replaceable pipe support platform. The replaceable pipe support platform is primarily used to support pipes of different diameters, while the pipe fitting pressure clamps above it are replaced simultaneously when the replaceable pipe support is replaced.

[0009] Furthermore, the pipe fitting pressure clamp is nested within the connecting clamp seat and limited by a locking bolt. The pipe fitting pressure clamp is used in conjunction with the replaceable pipe rack platform, and the lower part of the platform is connected to the equipment support platform. The connecting clamp seat is mainly used for limiting and fixing the pipe fitting pressure clamp, and during fixing, a locking bolt is also needed to penetrate both for further limiting and securing.

[0010] Furthermore, the equipment support platform is equipped with a frame, on which a triangular support is mounted. An auxiliary slide is mounted on the triangular support, and a sliding rod frame is mounted on the frame, with a connecting block on the sliding rod frame. The triangular support is mainly used to support the auxiliary slide, which needs to engage and slide with the platform to allow the platform to move laterally.

[0011] Furthermore, the upper surface of the connecting block is connected to the lower surface of the platform, the auxiliary sliding seat is slidably engaged with the sliding groove on the lower surface of the platform, the platform surface is fixed to the rotating seat, and the rear wall of the platform is fixed to the cutting assembly. The cutting assembly is mainly used to cut the pipes fixed on the platform, thereby realizing the cutting work of water conservancy construction pipes. Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention involves rotating the ball-headed rotating rod on the pipe support device during pipe cutting, while simultaneously adjusting the length with the help of a tension rod. This allows the extended support to be nested into the pipe to be cut, making it compatible with a rotating top support rod of the same diameter as the pipe, thus providing support to the inner wall of the pipe. Consequently, during cutting, the rotating top support rod provides support to the inner wall of the pipe, preventing deformation of the pipe opening caused by external cutting forces.

[0018] This utility model provides a pipe cutting device for water conservancy construction, including an equipment support platform 4, a pipe internal support device 1 fixed above the equipment support platform 4, a cutting component 2 installed behind the equipment support platform 4, and a pipe fitting feeding platform 3 arranged below the cutting component 2; a rotating seat 11 is provided inside the pipe internal support device 1, a ball-head rotating rod 12 is installed on the rotating seat 11, a tension rod 13 is connected to the ball-head rotating rod 12, a connecting support rod 14 is connected to the end of the tension rod 13, and an even number of extension support members 15 are installed on the connecting support rod 14. A platform body 31 is provided inside the pipe fitting feeding platform 3, an even number of inner clamping seats 32 are fixed on the surface of the platform body 31, an even number of connecting clamping seats 34 are installed on the upper surface of the inner clamping seats 32, a replaceable pipe support platform 33 is connected to the inner clamping seats 32, and an even number of pipe fitting pressing clamps 35 are arranged above the replaceable pipe support platform 33. The equipment support platform 4 is equipped with a frame 41, on which a triangular support frame 42 is installed. An auxiliary slide block 43 is installed on the triangular support frame 42. A slide rod frame 44 is installed on the frame 41, and a connecting block 45 is provided on the slide rod frame 44. An even number of fixing slots 154 are opened on an even number of extension support members 15. A threaded locking block 151 is installed on each fixing slot 154. A locking nail 152 is fixed on the surface of each threaded locking block 151. A rotating top support rod 153 is threadedly connected to the threaded locking block 151.

[0019] Furthermore, the cutting assembly 2 is mainly used for cutting water conservancy construction pipes, and the cutting assembly 2 also includes a motor, a cutter, a pushing electric rod and a fixing frame, so that the cutter slowly completes the pipe cutting work under the slow push of the electric rod.

[0020] Furthermore, the tension rod 13 can be stretched laterally so that when the pipe changes, it can be adapted to the center position of the pipe and the connecting support rod 14 together with the extension support 15 can be inserted into the pipe.

[0021] Furthermore, at least two extension supports 15 are provided, with a certain gap between them during installation. The gap is used to avoid the cutting blade when the cutting component 2 is cutting.

[0022] Furthermore, the rotating top support rod 153 is mainly used for threaded connection of the threaded locking block 151, so that it can be matched with different pipe diameters after the connection, and provide close support for its inner wall.

[0023] The working principle of this utility model is explained below: In use, this utility model involves installing the inner clamp 32 on the pipe fitting delivery platform 3 onto a replaceable pipe rack 33 with the same pipe diameter. Then, the pipe fitting pressure clamp 35 is nested into the connecting clamp 34, with a pin providing through-hole positioning. The platform 31 is then pushed, causing it to move laterally under the triangular support 42 (auxiliary slide 43) of the support platform 41, in conjunction with the slide rod 44 and connecting block 45. After moving to the desired position, the ball joint rod 12 on the rotating seat 11 is rotated, simultaneously stretching the tension rod 13 laterally. This causes the connecting support rod 14, along with the adjusted extension support 15, to adhere to the inner wall of the pipe. The rotating top support rod 153 supports the inner wall of the pipe, while the cutting assembly 2, with the assistance of the electric push rod, slowly cuts the pipe with its motor-driven cutter. The rotating top support rod 153 provides support to the inner wall of the pipe, preventing deformation of the pipe cut during cutting.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
