Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile cutting, in particular to a pipe pile cutting device. Background Art

[0002] Many tubular materials need to be processed before they are put into use, such as cutting or breaking. For cutting processing, the cutting device of the traditional cutting machine is to set the cutting mechanism on one side. After the tubular material falls into the cutting platform, there will be a clamping device in the platform to fix it, and then cut it after it is fixed. After cutting, the cut material is directly released and allowed to fall onto the conveyor belt. Although this method can meet the cutting and unloading work, a Chinese patent discloses a pipe pile cutting device (authorization announcement number CN107813003B). The patent technology discloses a pipe pile cutting device with a rectangular cutting platform and a cutting limit device on the cutting platform. The cutting limit device includes a lifting and positioning mechanism, a pushing mechanism, a cutting mechanism and a third limiting mechanism. A circular arc structure slide is provided on one side of the cutting platform. A first accommodating cavity with an upward opening is provided on the cutting platform. The third limiting mechanism includes two third limiting components symmetrically arranged in the first accommodating cavity. The pushing mechanism is arranged on the side of the cutting platform close to the two third limiting components. The lifting and positioning mechanism is arranged at the bottom of the cutting platform and is located directly below the two third limiting components. The cutting mechanism is arranged directly above the two third limiting components. The present invention allows the tubular material to be positioned and cut very stably in the cutting platform, and finally it is also very convenient to unload the material. The present invention adopts a simple structure and is easy to maintain in the later stage. This patented technology solves the problem that the clamping device is too simplified. After the cutting material is cut, it cannot be directly sent to the conveyor belt, but is allowed to fall in by itself. In this process, the safety of the material cannot be guaranteed.

[0003] However, in the prior art, waste materials are splashed when cutting pipe piles. The high-speed splashing waste materials are likely to injure people and pollute the environment. Therefore, it is necessary to solve the problem of centralized collection of waste materials when cutting pipe piles.

[0004] Therefore, those skilled in the art provide a pipe pile cutting device to solve the problems raised in the above background technology. Utility Model Content

[0018] Technical effects and advantages of this utility model:

[0019] The utility model can adjust the distance between the closed arc frame and the fixed frame by starting cylinder 2, so that the reset rods in the closed positioning structure 1 and the closed positioning structure 2 can contact the outer wall of the pipe pile.

The waste residue generated by cutting is collected by the dust suction groove connected to the vacuum cleaner and the dust suction telescopic tube, and stored in the dust storage box, which effectively prevents waste from splashing and injuring people and polluting the environment.

[0033] The spring 208 is mounted between the reset rod 206 and the closed arc frame 201. A cylinder 204 is installed between the closed arc frame 201 and the fixed frame 202. A vertical frame 205 is integrally fixed to the top of the closed arc frame 201. Cylinder 14 is mounted on the inner wall of the vertical frame 205 of the closed positioning structure 2. The output end of cylinder 14 is mounted on the cutting frame 15. A cutting wheel 16 for cutting pipe piles is rotatably mounted inside the cutting frame 15. The cutting wheel 16 is connected to a cutting motor 17.

[0034] The cutting motor 17 is used to actively drive the cutting wheel 16 to rotate. A dust collection slot 18 is formed through the bottom of the closed arc frame 201 of the closed positioning structure 1-2. A dust collection telescopic tube 19 is sealedly connected to the outside of the dust collection slot 18. The end of the dust collection telescopic tube 19, away from the dust collection slot 18, is connected to a dust collector 20.

[0038] The distance between the pipe pile placement plate 1 6 and the pipe pile placement plate 2 11 can be adjusted according to the length of the pipe pile, and the screw rod 1 4 can be manually rotated. After the screw rod 1 4 is rotated, the screw moving frame 5 can be screw-driven, so that the screw moving frame 5 drives the pipe pile placement plate 1 6 to move on the cutting frame 1.

[0041] The reset rods 206 in the closed positioning structure 1 2 and the closed positioning structure 2 3 are brought into contact with the outer wall of the pipe pile to be cut. When the closed arc frame 201 continues to move, the reset rods 206 are subjected to resistance from the pipe pile and stretch the spring 208 on the outer side of the telescopic rod 207, causing the reset rods 206 to move inside the closed arc frame 201. The reset rods 206 can be closed and aligned according to the outer shape of the pipe pile.
