Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cutting devices, in particular to a water conservancy project pipeline cutting device. Background Art

[0002] The pipe cutting device in water conservancy projects is a tool used to accurately cut pipes. For example, a pipe cutter is a commonly used device. It can be a disc cutter, a chain cutter or a hydraulic cutting tool, suitable for pipes of different materials and diameters.

[0003] The existing patent (publication number: CN221110113U) proposes a pipe cutting device for water conservancy projects, including a base, on which are installed several spaced pipe support structures; a mounting seat is installed on the base through a walking structure, and the mounting seat is U-shaped. A pushing cylinder is fixed on the mounting seat, and the cylinder rod of the pushing cylinder passes through the mounting seat and is fixed with a tool holder, and a tool holder is fixed on the tool holder, and a tool shaft rotates on the tool holder.

[0004] The mounting frame is provided with a ring frame rotating structure for driving the ring frame to rotate, and the ring frame is provided with a plurality of clamping and positioning structures for clamping and positioning the pipe. The pipe cutting device for water conservancy projects has the advantages of being able to automatically cut the pipe, having a stable structure, being easy to use, and having high efficiency.

[0005] However, in actual use, the following deficiencies still exist, for example: the existing water conservancy project pipe cutting device cannot meet the requirements of clamping and rotating cutting of pipes of different diameters. If the pipe cutting device cannot adapt well to pipes of different diameters, then in actual operation, it will take extra time to adjust the equipment or use multiple devices of different specifications, which will undoubtedly reduce the overall work efficiency. Accidents caused by unstable pipe fixation, such as pipe falling off, cutting machine blade slipping, etc., may directly threaten the safety of the operator. Therefore, the utility model proposes a water conservancy project pipe cutting device to solve the above problems. Utility Model Content

[0008] The clamping and rotating assembly includes a second supporting seat, a fixed block is fixedly connected to the second supporting seat, a rotating block is rotatably connected in the fixed block, a limiting block is slidably connected in the fixed block, a supporting block is fixedly connected to the fixed block, a rotating arm is rotatably connected to the supporting block, a limiting slot is provided on the limiting block, and one end of the rotating arm is slidably connected in the limiting slot;

[0012] As a preferred embodiment, the second supporting seat is slidably connected to the slide rail, a transmission motor is installed on the fixed block, and the rotating block is fixedly connected to the output end of the transmission motor.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1-5 As shown, this embodiment provides a technical solution: a water conservancy project pipeline cutting device, comprising a base plate 1 and a cutting machine 3, a clamping and rotating assembly 4 is provided on the base plate 1, and an auxiliary clamping assembly 5 is provided on the clamping and rotating assembly 4;

[0034] like Figure 1 as well as Figures 3-5 As shown, the clamping and rotating assembly 4 includes a second support base 41, a fixed block 42 is fixedly connected to the second support base 41, a rotating block 44 is rotatably connected to the fixed block 42, a limiting block 46 is slidably connected to the fixed block 42, a supporting block 48 is fixedly connected to the fixed block 42, a rotating arm 49 is rotatably connected to the supporting block 48, a limiting slot 47 is defined on the limiting block 46, and one end of the rotating arm 49 is slidably connected to the limiting slot 47;

[0035] like Figure 1 as well as Figure 3 as well as Figure 5As shown, the auxiliary clamping assembly 5 includes a support rod 51, which is slidably connected to a limit plate 52 on the support rod 51, and a fixed plate 53 is fixedly connected to the support rod 51. The limit plate 52 is rotatably connected to a first rotating rod 54, and a third rotating rod 56 is rotatably connected to the side of the fixed plate 53 close to the second rotating rod 55. The other end of the first rotating rod 54 is rotatably connected to a clamping plate 57. In water conservancy projects, accurate cutting of pipes is crucial to the efficiency and safety of the entire system. The operator first starts the electric telescopic rod 45, and the output end of the rod pushes the limit block 46 connected thereto to move outward. The limit block 46 acts through the limit groove 47 opened thereon, causing the rotating arm 49 to expand outward. This expansion action enables the rotating arm 49 to adapt to pipes of different diameters and effectively clamp and fix their inner walls. When the limit block 46 is pushed outward, the limit block 46 will push the limit plate 52 to move on the support rod 51, so that the limit plate 52 drives the third rotating rod 56 to move. A rotating rod 54 rotates, causing the first rotating rod 54 to drive the second rotating rod 55 and the third rotating rod 56 to rotate, thereby causing the first rotating rod 54, the second rotating rod 55 and the third rotating rod 56 to drive the clamping plate 57 to push outward, and the clamping plate 57 assists in clamping and fixing the pipe. Subsequently, after the pipe is firmly clamped, the operator will start the transmission motor 43. The output end of this motor drives the rotating block 44 and the limit block 46 connected to the rotating block 44, thereby driving the clamped pipe to rotate. This rotation mechanism enables the pipe to rotate within the working range of the cutting machine 3. The position of the cutting machine 3 is adjusted in advance according to the length and shape of the pipe to be cut, ensuring the accuracy and efficiency of the cutting process. As the pipe rotates, the cutting machine 3 cuts it accurately, whether it is straight cutting or curve cutting, it can be completed accurately, thereby solving the technical problem of stable positioning cutting of pipes of different diameters.

[0036] The above solutions still have the problem that when the clamped and fixed pipe needs to be cut, it cannot meet the problem of rapid cutting of the pipe, such as Figures 1-2 As shown: a slide rail 6 is fixedly connected to the bottom plate 1, a first support seat 2 is slidably connected to the slide rail 6, a cutting machine 3 is arranged on the first support seat 2, and a nut 7 is threadedly connected to the first support seat 2. Since the slide rail 6 is fixedly connected to the bottom plate 1, the first support seat 2 and the second support seat 41 can be moved on the slide rail 6, which is convenient for adjusting the position where the pipe needs to be cut. Since the cutting machine 3 is arranged on the first support seat 2, the first support seat 2 can support and fix the cutting machine 3;

[0037] like Figure 1 as well as Figures 3-5As shown, the second support base 41 is slidably connected to the slide rail 6, and a transmission motor 43 is installed on the fixed block 42, and the rotating block 44 is fixedly connected to the output end of the transmission motor 43. Since the second support base 41 is slidably connected to the slide rail 6, when the second support base 41 moves on the slide rail 6, the slide rail 6 can play a guiding and limiting role in the movement of the second support base 41. Since the transmission motor 43 is installed on the fixed block 42, the fixed block 42 can support and fix the transmission motor 43. Since the rotating block 44 is fixedly connected to the output end of the transmission motor 43, after the transmission motor 43 is started, the output end of the transmission motor 43 can drive the rotating block 44 to rotate. An electric telescopic rod 45 is installed in the rotating block 44, and the limit block 46 is fixedly connected to the output end of the electric telescopic rod 45. Since the electric telescopic rod 45 is installed in the rotating block 44, and the limit block 46 is fixedly connected to the output end of the electric telescopic rod 45, when the electric telescopic rod 45 is started, the electric telescopic rod 45 is rotated. The output end can drive the limit block 46 to move on the fixed block 42, and the other end of the rotating arm 49 is rotatably connected to the support plate 410, and the rubber plate 411 is fixedly connected to the support plate 410. Since the other end of the rotating arm 49 is rotatably connected to the support plate 410, and the rubber plate 411 is fixedly connected to the support plate 410, the rubber plate 411 can fit more closely with the inner wall of the pipe, and the rubber plate 411 can increase the friction with the pipe, which is convenient for the rotation of the pipe. The support rod 51 is fixedly connected to the fixed block 42, and the second rotating rod 55 is rotatably connected to the fixed plate 53. The second rotating rod 55 and the third rotating rod 56 are both rotatably connected to the clamping plate 57. Since the support rod 51 is fixedly connected to the fixed block 42, the fixed block 42 can support and fix the support rod 51. Since the second rotating rod 55 and the third rotating rod 56 are both rotatably connected to the clamping plate 57, the second rotating rod 55 and the third rotating rod 56 can drive the clamping plate 57 to move when they rotate.

[0038] Working principle:

[0039] like Figures 1-5As shown, in water conservancy projects, precise cutting of pipes is crucial to the efficiency and safety of the entire system. The operator first places the water conservancy project pipe on the first support seat 2, adjusts the first support seat 2 and the second support seat 41 to the appropriate position through the provided slide rail 6, and starts the electric telescopic rod 45. The output end of the rod pushes the limit block 46 connected thereto to move outward, and the limit block 46 acts through the limit groove 47 opened thereon to cause the rotating arm 49 to expand outward. This expansion action enables the rotating arm 49 to adapt to pipes of different diameters and effectively clamp and fix their inner walls. When the limit block 46 is pushed outward, the limit block 46 will push the limit plate 52 to move on the support rod 51, so that the limit plate 52 drives the first rotating rod 54 to rotate, so that the first rotating rod 54 drives the second rotating rod The movable rod 55 and the third rotating rod 56 rotate, so that the first rotating rod 54, the second rotating rod 55 and the third rotating rod 56 drive the clamping plate 57 to push outward, and the clamping plate 57 assists in internal clamping and fixing it in the pipe. Then, when the pipe is firmly clamped, the operator will start the transmission motor 43. The output end of this motor drives the rotating block 44 and the limit block 46 connected to the rotating block 44, thereby driving the clamped pipe to rotate. This rotation mechanism enables the pipe to rotate within the working range of the cutting machine 3, move the first support seat 2 to the required cutting position, tighten the nut 7 to fix the first support seat 2, ensure the accuracy and efficiency of the cutting process, and as the pipe rotates, the cutting machine 3 cuts it accurately, whether it is straight cutting or curve cutting, it can be completed accurately.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
