Description

Technical Field

[0001] This utility model relates to the field of pipeline cutting technology in water conservancy projects, specifically to a pipeline cutting device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Only by building water conservancy projects can water flow be controlled, floods be prevented, and water volume be regulated and distributed. Pipelines are an indispensable part of water conservancy projects. In fact, during the process of connecting pipelines, it is often necessary to cut water conservancy pipelines into different lengths according to the usage requirements.

[0003] For example, the disclosed utility model provides "a pipe cutting device for water conservancy projects", with patent number: 202321553444.9. This patent includes a cutting box, with an inlet and an outlet respectively opened at both ends of the outer side wall of the cutting box. A placement plate is installed inside the inlet and outlet, and a fixing frame is installed at the bottom of the placement plate. Through the limiting mechanism and the cutting auxiliary mechanism, the beginning and end of the pipe can be limited and fixedly clamped, thereby greatly improving the cutting stability and cutting effect of the pipe inside the cutting box.

[0004] Although the aforementioned patent solves the problem that most existing pipe cutting equipment is semi-automatic, requiring manual movement and handling of the pipe for cutting, resulting in low cutting efficiency, it still has drawbacks such as inconvenient material handling and unsatisfactory dust removal. After the pipe is cut, it remains inside the cutting equipment, making it difficult to handle. Furthermore, the simple chip collection trough cannot prevent the flying of chips generated during cutting. Therefore, the purpose of this utility model is to improve the efficiency of pipe cutting by setting up a clamping structure that facilitates material handling and a dust removal mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe cutting device for water conservancy projects, which has the advantage of high cutting efficiency. It solves the problems of existing pipe cutting devices where the pipe remains inside the cutting device after cutting, making it difficult to remove the material, and the inability to avoid the flying of debris generated during cutting by simply collecting the debris in the chip collection trough.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe cutting device for water conservancy engineering, comprising a cutting chamber, guide rails fixedly connected to both sides of the bottom of the inner cavity of the cutting chamber, a slider movably connected to the inner cavity of the guide rails, a push-pull frame fixedly connected to the top of the slider, a partition fixedly connected to the bottom of the inner cavity of the push-pull frame, dust suction ports provided on both sides of the top of the partition, dust collection boxes fixedly connected to both sides of the bottom of the partition, a filter screen provided in the inner cavity of the dust collection box, and a fan fixedly connected to opposite sides of the dust collection box. Both sides of the push-pull frame are threaded with screws, and one end of the screw is movably connected to a clamping plate. The bottom of the cutting chamber is fixedly connected to a support frame, and the inner cavity of the support frame is fixedly connected to a main unit. The top of the cutting chamber has an opening, and the inner cavity of the opening is fixedly connected to a crossbar. The surface of the crossbar is movably connected to a movable seat, and the inner cavity of the movable seat is connected to an electric push rod. The telescopic shaft of the electric push rod is fixedly connected to a mounting frame, and the inner cavity of the mounting frame is fixedly connected to a motor. The output shaft of the motor is fixedly connected to a cutting disc.

[0007] Preferably, support pads are fixedly connected to both sides of the bottom of the support frame, and the bottom of the support pads is provided with anti-slip texture.

[0008] Preferably, the top and bottom of the opposite side of the clamping plate are fixedly connected to limit rods, and the limit rods are connected through the push-pull frame.

[0009] Preferably, both sides of the top of the mounting bracket are fixedly connected to a fixing frame, and a vertical rod is connected through the inner cavity of the fixing frame. The top of the vertical rod is fixedly connected to the bottom of the movable seat.

[0010] Preferably, positioning frames are fixedly connected to both sides of the bottom of the cutting chamber, and ball bearings are movably connected to the opposite side of the positioning frames, with the other side of the ball bearings contacting the surface of the push-pull frame.

[0011] Preferably, the dust collection box has a sealed door on the front, and a handle is fixedly connected to the front of the sealed door.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a partition, a dust suction port, a dust collection box, a filter, and a fan. As the cutting disc cuts the water pipe, the fan is turned on, and the operation of the fan creates negative pressure in the inner cavity of the dust collection box, which in turn creates suction at the dust suction port on the surface of the partition, thereby sucking the cutting debris into the inner cavity of the dust collection box. After the pipe cutting is completed, the inner cavity of the dust collection box can be cleaned.

[0014] 2. This utility model uses a guide rail, slider, push-pull frame, screw, and clamping plate to place the water pipe on the anti-slip pad on the top of the partition. By turning the screw by hand, as the screw rotates in the threaded sleeve on the surface of the push-pull frame, the two screws move closer to each other. The screw drives the clamping plates to move closer to each other until one side of the clamping plate is in close contact with the surface of the water pipe, thereby clamping and fixing the water pipe. After cutting, hold the handle on the front of the push-pull frame and pull out the push-pull frame and the cut water pipe inside its cavity. Attached Figure Description

The bottom of the cutting chamber 1 is fixedly connected to a support frame 12. The inner cavity of the support frame 12 is fixedly connected to a main unit housing 13. The top of the cutting chamber 1 has an opening 14. The inner cavity of the opening 14 is fixedly connected to a crossbar 15. The surface of the crossbar 15 is movably connected to a movable seat 16. The inner cavity of the movable seat 16 is connected to an electric push rod 17. The telescopic shaft of the electric push rod 17 is fixedly connected to a mounting frame 18. The inner cavity of the mounting frame 18 is fixedly connected to a motor 19. The output shaft of the motor 19 is fixedly connected to a cutting disc 20.

[0022] Support pads are fixedly connected to both sides of the bottom of the support frame 12, and the bottom of the support pads is provided with anti-slip texture.

[0023] By using the above technical solution, and by setting up support pads, two support pads with anti-slip function are set on both sides of the bottom of the support frame 12, which can greatly improve the anti-slip performance of the support frame 12, thereby providing stable support for the bottom of the cutting chamber 1.

[0024] Limiting rods are fixedly connected to the top and bottom of the opposite side of the clamping plate 11, and the limiting rods are connected through the push-pull bracket 4.

[0025] By using the above technical solution, by setting a limiting rod, the limiting rod moves with the clamping plate 11 in the limiting hole on the surface of the push-pull frame 4, so that the clamping plate 11 will not shake much when it moves.

[0026] Mounting bracket 18 has fixed brackets on both sides of its top, and vertical rods are connected through the inner cavity of the fixed brackets. The top of the vertical rods is fixedly connected to the bottom of the movable base 16.

[0027] By using the above technical solution, and by setting up a fixed frame and a vertical rod, the fixed ring moves along with the mounting frame 18 on the surface of the vertical rod, so that the mounting frame 18 and the motor 19 inside its cavity will not shake when moving, thus achieving higher stability.

[0032] In use, first connect the pipe cutting equipment to the power supply, place the water pipe on the anti-slip pad on top of the partition 5, and turn the screw 10 by hand. As the screw 10 rotates in the threaded sleeve on the surface of the push-pull frame 4, the two screws 10 move closer to each other. The screws 10 drive the clamping plates 11 to move closer to each other until one side of the clamping plates 11 is in close contact with the surface of the water pipe, thus clamping and fixing the water pipe. As the cutting disc 20 cuts the water pipe, turn on the fan 9. The operation of the fan 9 creates negative pressure in the inner cavity of the dust collection box 7, which in turn creates suction at the dust suction port 6 on the surface of the partition 5, thereby sucking the cutting debris into the inner cavity of the dust collection box 7. After the pipe cutting is completed, hold the handle on the front of the push-pull frame 4 and pull out the push-pull frame 4 and the cut water pipe in its inner cavity through the handle to clean the inner cavity of the dust collection box 7.
