DETAILED DESCRIPTION
[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments:
[0023] Pipe end auxiliary devices for pipeline grooving, such as Figure 1-Figure 4 As shown, it includes a support 1, a bracket 3 and a lifting mechanism 2; the bracket 3 is supported on the support 1 in a vertically liftable manner through the lifting mechanism 2, that is, under the action of the lifting mechanism 2, the bracket 3 can be raised or lowered to adjust the height position.
[0024] The bracket 3 includes a horizontally arranged bottom plate 31 and a front side plate 32 and a rear side plate 33 arranged longitudinally front and rear along the bottom plate 31; the bottom end of the front side plate 32 is fixed to the front end of the bottom plate 31, and the top end extends vertically upward; the bottom end of the rear side plate 33 is fixed to the rear end of the bottom plate 31, and the top end extends vertically upward. In this way, a groove-shaped structure with an open top is formed by the bottom plate 31, the front side plate 32 and the rear side plate 33, and the groove-shaped structure is light in weight and high in strength. A middle bracket 36 is arranged in the middle of the top of the front side plate 32 and the rear side plate 33, and a limiting groove 37 is arranged on the left and right sides of the top of the front side plate 32 and the rear side plate 33, that is, a limiting groove 37 is arranged on the left side of the middle bracket 26, and a limiting groove 37 is also arranged on the right side. The bracket 3 is provided with two rollers 38, which are located on the left and right sides of the middle bracket 36. The shaft head of one end of the roller 38 is clamped in the limit groove 37 of the front side plate 32, and the shaft head of the other end is clamped in the limit groove 37 of the rear side plate 33. The roller 38 is installed by the cooperation between the limit groove 37 and the shaft head of the roller 38. A longitudinally extending lifting area is formed between the two rollers 38 and the middle bracket 36.
[0025] During operation, the grooved end of the pipe to be grooved is placed in the groover, and the pipe end auxiliary device for grooving the pipe is placed at the end of the grooved pipe. The end of the pipe to be grooved is placed between the two rollers 38 and the middle bracket 36 to form a longitudinally extending lifting area. Then, the jacking mechanism 2 is used to adjust the grooved end of the pipe to be grooved and the end to be at the same height, that is, the pipe to be grooved is kept horizontal, and finally the groover performs grooving.
[0026] The middle bracket 26 plays a supporting role at the bottom of the pipe, and the rollers 38 play a supporting role at both sides of the pipe. The middle bracket 26 and the two rollers 38 form three-point support along the circumferential direction of the pipe, and the support stability is good.
[0027] In order to adapt to pipes of different diameters, preferably, at least two limit grooves 37 are arranged on the left and right sides of the top of the front side plate 32 and the rear side plate 33. In this arrangement, the distance between the two rollers 38 can be adjusted by installing the rollers 38 in different limit grooves 37, so as to adapt to pipes of various diameters and have better adaptability.
[0028] In order to further improve the strength of the bracket 3 , a left side plate 34 and a right side plate 35 are connected to the left and right ends of the bottom plate 31 . The left side plate 34 , the right side plate 35 , the front side plate 32 and the rear side plate 33 surround and form a square frame.
[0029] A set of lifting mechanisms 2 can be arranged along the left and right sides of the bracket 3 for lifting at the same time. However, in order to simplify the structure, in this embodiment, only one set of lifting mechanisms 2 is provided, and the lifting mechanism 2 is arranged at the center of the bottom plate 31. In order to prevent the bracket 3 from tilting during the lifting process, guide mechanisms 4 are provided on the left and right sides of the lifting mechanism 2.
[0030] The lifting mechanism 2 can be a hydraulic cylinder, a gear rack mechanism, etc. In this embodiment, the lifting mechanism 2 includes a lifting rod 21 and a worm gear 23; the worm of the worm gear 23 is horizontally arranged, the axis of the worm of the worm gear 23 is vertically arranged, and a vertical threaded through hole is arranged in the center; the lifting rod 21 is a threaded rod, the lifting rod 21 is threadedly matched with the threaded through hole of the worm gear, and its top end is detachably connected to the bottom end of the bracket 3; the worm gear 23 is installed on the support 1, and a driving hand wheel 22 is arranged at one end of the worm.
[0031] During operation, the driving hand wheel 22 drives the worm of the worm gear 23 to rotate forward, and the worm gear rotates accordingly. Since the top end of the lifting rod 21 is connected to the bracket 3, the lifting rod 21 cannot rotate along with the worm gear under the restriction of the guide mechanism 4. The two rotate relative to each other, so that the worm gear pushes the lifting rod 21 to move upward, thereby lifting the bracket 3. On the contrary, the driving hand wheel 22 drives the worm of the worm gear 23 to rotate in the opposite direction, and the worm gear pushes the lifting rod 21 to move downward, thereby lowering the bracket 3.
[0032] The guide mechanism 4 can adopt the structural form of a guide rail and a slide groove. In this embodiment, the guide mechanism 4 includes a pin shaft 41 and a guide seat 42. The guide seat 42 is provided with a vertically penetrating guide hole 43 adapted to the pin shaft 41. The pin shaft 41 is vertically slidably inserted in the guide hole 43, and its top end is connected to the bottom plate 31 of the bracket 3. The guide mechanism 4 has a simple structure and is easy to manufacture.
