DETAILED DESCRIPTION

[0029] Reference Figure 1-8 , a pipe cutting device for construction engineering, comprising:

[0030] A rack 1, on which a control component 7 is fixedly disposed, and through which various components and parts in the device are controlled for use;

[0031] The positioning and conveying assembly 2 positions the pressure on both sides of the pipeline 3 and transports it, so that the position to be cut of the pipeline 3 can be conveniently conveyed to the bottom of the cutting assembly 4. The positioning and conveying assembly 2 includes fixed frames 21 arranged on both sides, each fixed frame 21 is connected to a conveying component, each conveying component includes a plurality of conveying rollers 22, each conveying roller 22 is connected to a conveying shaft 23, each conveying shaft 23 is connected to a transmission wheel 24, and the plurality of transmission wheels 24 are connected by a conveyor belt 25. The two fixed frames 21 are respectively equipped with a rotating motor 26, and each rotating motor 26 is respectively connected to a conveying shaft 23;

[0032] The positioning and conveying assembly 2 also includes a positioning component, which includes two hydraulic cylinders 27 arranged on both sides of the cutting blade 41. The movable end of each hydraulic cylinder 27 is fixedly connected to a pressure block 28. The pipeline 3 is positioned by the two groups of pressure blocks 28 and a pressure block 29 fixedly arranged on the frame 1.

[0033] The cutting assembly 4 includes a circular cutting blade 41, which is located in the middle of the positioning and conveying assembly 2 and is used to cut the pipe 3. The cutting assembly 4 also includes a protective sleeve 42, which is sleeved on the outer side of the cutting blade 41 and is rotatably connected to the cutting blade 41. The protective sleeve 42 is fixedly connected to a chassis 43, a driving motor is provided in the chassis 43, and the output shaft of the driving motor passes through the protective sleeve 42 and is connected to the cutting blade 41. The chassis 43 is connected to a hydraulic cylinder 2 44, and the two sides of the hydraulic cylinder 2 44 are respectively movably connected to the chassis 43 and the frame 1, the protective sleeve 42 is connected to a rotating frame 1 46 through two rotating arms 45 and a rotating shaft 1 48 on both sides, and the rotating frame 1 46 is installed on the frame 1 through a mounting plate 47.

[0034] The grinding component 5 can grind the end faces of the cutting disc 41 and the two pipes 3 after cutting respectively by rotation. The grinding component 5 is connected to the cutting component 4 by a connecting component 6. The grinding component 5 includes a rotating frame 51 arranged on the mounting plate 47. The rotating frame 51 is connected to two rotating plates 53 through a rotating shaft 52. The two rotating plates 53 are symmetrically arranged on both sides of the cutting disc 41. The other ends of the two rotating plates 53 are connected by a bracket rod 54. The position of the bracket rod 54 will meet the rotation cutting space of the cutting disc 41 for the pipe 3. An incomplete spherical shell 55 is fixedly connected to the middle part of each rotating plate 53. A sphere 56 is movably connected to each spherical shell 55 through an elastic component. Each sphere 56 has a movable space in the spherical shell 55 along the axial direction of the pipe 3. In the initial state, the two spheres 56 will be in a state of being offset. The two spheres 56 rotate around the rotating shaft 52 until the geometric center point of the sphere 56 at the pipe 3 coincides with the central axis of the pipe 3.

[0035] The connecting component 6 includes a sleeve 61 connected to the rotating shaft 48, a torsion spring is connected between the rotating shaft 48 and the sleeve 61, and relative rotation can be generated. After the relative rotation is generated, the torsion spring will generate pressure and have the function of restoring the relative rotation between the rotating shaft 48 and the sleeve 61 to the initial position, the sleeve 61 is connected to the synchronous wheel 1 62, the synchronous wheel 1 62 is connected to the synchronous wheel 2 64 through the synchronous belt 63, the synchronous wheel 2 64 is connected to the rotating shaft 2 52, and two inclined brackets 65 are provided in the mounting plate 47. The two inclined brackets 65 are respectively located under the two rotating plates 53, and a groove 66 cooperating with the ball shell 55 is opened in the inclined bracket 65, and a vibration plate is provided in the groove 66, so that the ball shell 55 is connected in the groove 66 so that the ball shell 55 drives the ball 56 to vibrate.

[0036] When the present invention is in use, the cutting blade 41 is connected to the rotating arm 45 and the hydraulic cylinder 44 through the protective sleeve 42. Therefore, when the hydraulic cylinder 44 is extended, the cutting blade 41 will rotate around the rotating shaft 48 and cut the pipe 3. Grinding components 5 are arranged on both sides of the cutting blade 41. The grinding components 5 abut the cutting blade 41 through two balls 56 on both sides. In the initial state, the two balls 56 abut against each other. Therefore, each time the cutting blade 41 cuts the pipe 3, it needs to pass between the two abutting balls 56 and compress the elastic component. In this way, on the one hand, the two balls can grind the cutting surface of the cutting blade 41 when the cutting blade 41 passes through. On the other hand, after the cutting blade 41 passes through the two balls 56, the pressure abutment of the two balls 56 on both sides of the cutting blade 41 can stably realize the cutting process.

[0037] The two balls 56 in the grinding assembly 5 can also play the role of grinding the ends of the two pipes 3 after cutting. After the cutting blade 41 completes cutting the pipe 3, the two pipes 3 are conveyed in a direction away from each other through the positioning and conveying assembly 2, and then the rotating plate 53 is continued to be rotated so that the center points of the two balls 56 are located on the axes of the two pipes 3, which is also the rotation limit point of the rotating plate 53. At the same time, the two rotating plates 53 are respectively positioned in coordination with the inclined bracket 65. At this time, the two pipes 3 are continued to be conveyed in a direction close to each other through the positioning and conveying assembly 2. After the two pipes 3 are abutted against the two balls 56, the positioning component is started to pressure-position the two pipes 3, and the vibration plate is started so that the two balls 56 respectively grind the ends of the abutting pipes 3.

[0038] When the present invention is in use, the grinding assembly 5 and the cutting assembly 4 are connected by the synchronous wheel structure and the torsion spring, wherein the rotation cutting angle of the rotating arm 45 in the cutting assembly 4 is greater than the rotation grinding angle of the rotating plate 53 in the grinding assembly 5. Therefore, when the cutting blade 41 has not cut the pipe 3, the two rotating plates 53 in the grinding assembly 5 have already abutted against the outer wall of the pipe 3. When the cutting blade 41 continues to rotate under the action of the rotating arm 45, a certain rotation difference will be generated in the synchronous wheel structure, so that the shaft sleeve 61 and the rotating shaft 48 will rotate relative to each other, and the torsion spring will be compressed, and then the cutting blade 41 will be cut to the pipe 3. When the sheet 41 completes the cutting and rotates in the opposite direction to leave the pipe 3, the torsion spring will still be in a compressed state. At this time, the positioning and conveying assembly 2 will separate the two cut pipes 3 from each other, and release the rotation limit of the pipe 3 on the transfer plate 53 in the grinding assembly, so that the two transfer plates 53 can rotate to the extreme rotation position where the ball 56 cooperates with the end of the pipe 3 under the action of the torsion spring, and the transfer plate 53 cooperates with the inclined bracket 65. At this time, the grinding work of the cut ends of the two pipes 3 can be realized to avoid burrs and curling at the cross section, which may cause harm to the construction workers.

[0039] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
