[0026] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.
[0027] This utility model provides a pipe bending device for construction sites, see [link]. Figures 1 to 4The pipe bending device at the construction site includes a mounting frame 1, an active pipe bending roller 4, a driven pipe bending roller 3, and an adjusting mechanism 2. The mounting frame 1 has a vertically oriented groove 111 in its middle, and a movable plate 7 is slidably disposed within the groove 111. The adjusting mechanism 2 is located at the top of the mounting frame 1 and is connected to the movable plate 7. The adjusting mechanism 2 drives the movable plate 7 to move vertically up and down. The active pipe bending roller 4 is mounted on the movable plate 7 and has a crank handle 5. Two driven pipe bending rollers 3 are horizontally spaced on the mounting frame 1 and symmetrically arranged on both sides of the active pipe bending roller 4.
[0028] Specifically, the mounting frame 1 includes a mounting base plate 12 and a mounting upright plate 11. The mounting upright plate 11 is vertically connected to the mounting base plate 12. The sliding groove 111 is disposed on the mounting upright plate 11. The adjusting mechanism 2 is disposed on the top of the mounting upright plate 11. The driven bending roller 3 is disposed on the mounting upright plate 11. In this embodiment, the mounting upright plate 11 has an overall "U"-shaped structure, and the two driven bending rollers 3 are disposed at the lower ends of the "U"-shaped mounting upright plate 11. Bolt holes are provided on the mounting base plate 12, which can be fixed to the bracket by bolts or fixed to the bottom surface of the construction site by expansion bolts.
[0029] When using the pipe bending device at the construction site, the square or round pipe to be bent is placed between the active bending roller 4 and two driven bending rollers 3. The height of the active bending roller 4 is adjusted by the adjusting mechanism 2. Then, the active bending roller 4 is rotated by hand by turning the crank handle 5, thereby bending the square or round pipe. During the bending process, the height of the active bending roller 4 can be continuously adjusted by the adjusting mechanism 2, so that the square or round pipe reaches the required curvature.
[0030] The adjusting mechanism 2 includes a rotating shaft 21, a rotating ring 22 and a rotating handle 23. The rotating ring 22 is fixedly connected to the top of the mounting bracket 1 and is located directly above the sliding groove 111. An internal thread is provided inside the rotating ring 22, and an external thread matching the internal thread is provided on the rotating shaft 21. The rotating shaft 21 is screwed onto the rotating ring 22. The lower end of the rotating shaft 21 is rotatably connected to the movable plate 7, and the rotating handle 23 is fixedly connected to the upper end of the rotating shaft 21. Among them, a circular connecting plate 24 is provided at the lower end of the rotating shaft 21, and a connecting groove 71 is provided at the upper end of the movable plate 7. The lower end of the rotating shaft 21 is rotatably connected to the connecting groove 71 of the movable plate 7 through the circular connecting plate 24. In this embodiment, the rotating handle 23 has a "cross" structure. By rotating the rotating handle 23, the rotating shaft 21 can be driven to rotate. Since the rotating shaft 21 is screwed onto the rotating ring 22, the up and down movement of the rotating shaft 21 can be realized, and then the movable plate 7 and the active bending roller 4 provided on the movable plate 7 can be driven to move up and down. In this embodiment, the groove on the movable plate 7 has a "convex" structure so that the circular connecting plate 24 at the lower end of the rotating shaft 21 will not come out of the groove. Sealing plates 8 are respectively detachably connected to both ends of the movable plate 7 through bolts. The sealing plates 8 can block both ends of the groove of the movable plate 7, so that the circular connecting plate 24 at the lower end of the rotating shaft 21 will not come out from both sides of the movable plate 7.
[0031] Further, the rotating crank handle 5 includes a crank handle rod 51 and a rotating handle 52. The rotating handle 52 is rotatably connected to the first end of the crank handle rod 51, and the second end of the crank handle rod 51 is fixedly connected to the active bending roller 4.
[0032] Further, the active bending roller 4 includes an active fixed shaft 41 and an active rotating roller 42. The active rotating roller 42 is rotatably connected to the active fixed shaft 41, and the active fixed shaft 41 is fixedly connected to the movable plate 7; the driven bending roller 3 includes a driven fixed shaft 31 and a driven rotating roller 32. The driven rotating roller 32 is rotatably connected to the driven fixed shaft 31, and the driven fixed shaft 31 is fixedly connected to the mounting bracket 1. In this embodiment, the active bending roller 4 and the driven bending roller 3 are respectively detachably connected to the mounting vertical plate 11, so that they can be replaced to meet different bending requirements. Specifically, when implementing, screw and nut fixing structures can be provided at the ends of the active fixed shaft 41 of the active bending roller 4 and the driven fixed shaft 31 of the driven bending roller 3, and they are connected to the mounting vertical plate 11 through the screw and nut fixing structures.
[0033] Furthermore, the outer end of the active rotating roller 42 is provided with a fixed flange plate 43, and the second end of the crank arm 51 of the crank handle 5 is provided with a connecting flange plate 53. The connecting flange plate 53 is fixedly connected to the fixed flange plate 43 by multiple bolts. In this embodiment, the fixed flange plate 43 is provided with two snap-fit protrusions, and the connecting flange plate 53 is provided with two snap-fit grooves that match the snap-fit protrusions. The snap-fit grooves of the connecting flange plate 53 snap onto the snap-fit protrusions of the fixed flange plate 43, thereby facilitating quick alignment and positioning of the bolt holes on the connecting flange plate 53 and the threaded holes on the fixed flange plate 43. At the same time, it can also provide sufficient support to prevent damage to the bolts due to excessive torque when cranking the crank handle 5.
[0034] Furthermore, two side plates 13 are vertically arranged on one side of the mounting frame 1. A set of spare bending rollers is detachably connected to each of the two side plates 13. Each set of spare bending rollers includes one active spare bending roller 61 and two driven spare bending rollers 62. The active spare bending roller 61 and the driven spare bending roller 62 each have annular grooves in their middle portions; the annular grooves on the rollers of the two sets of spare bending rollers are of different sizes. In this embodiment, the active bending roller 4 and the driven bending roller 3 mounted on the mounting plate 11 have smooth surfaces, allowing for bending of square tubes. The annular grooves on the rollers of the two sets of spare bending rollers can be used to bend round tubes of different diameters. In practical use, the active bending roller 4 and the driven bending roller 3 can be removed from the mounting plate 11 and replaced with the active spare bending roller 61 and the driven spare bending roller 62.
[0035] In summary, the pipe bending device provided by this utility model allows square or round pipes to be placed between the active bending roller and two driven bending rollers. By turning the crank, the active bending roller can be driven to rotate, and pipe bending can be easily achieved on the construction site. The adjustment mechanism on the mounting frame can adjust the height of the active bending roller, thereby adjusting the degree of bending and meeting various pipe bending needs on the construction site.
