Detailed Description

The following description of the embodiments of the present utility model will be made more fully hereinafter with reference to the accompanying drawings, in which embodiments of the utility model are shown, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 3, the integral flange assembly for the rotary drilling rig provided by the embodiment of the utility model comprises a front flange 1, a rear flange 2, a pipe 5 and a plurality of flange rib plates 6, wherein the number of the flange rib plates 6 can be between 10 and 12, and the outer diameter of the front flange 1 is required to be matched with the size of a bearing on a follow-up frame of the rotary drilling rig so that the front flange 1 can be mounted on the bearing of the follow-up frame; the outer diameter of the rear flange 2 is matched with the size of a chassis on a driving sleeve of the rotary drilling rig.

The rear flange 2 is connected with the outermost drill rod, and a rubber shock absorber 4 is arranged on one side of the rear flange 2 away from the front flange 1. The thickness of the front flange 1 and the rear flange 2 is 40 mm, and the thickness can meet the structural strength requirement of the flange. The front flange 1 and the rear flange 2 are respectively fixed at two ends of the pipe 5, the length of the flange rib plate 6 is 720 mm or 180 mm, and the length of the flange rib plate is determined according to the distance between the front flange 1 and the rear flange 2. The flange rib plates 6 are uniformly welded on the pipe 5 in the circumferential direction, and two ends of the flange rib plates 6 are respectively welded with the front flange 1 and the rear flange 2. Because the front flange 1 and the rear flange 2 are connected by the complete flange rib plate 6, compared with the prior short rib plate 3, the extrusion resistance of the flange assembly is enhanced.

In order to further optimize the flange rib plate 6, dead weight is reduced while structural strength is ensured. The flange rib plate 6 comprises a front rib plate head 61, a rear rib plate head 62 and a connecting part 63, wherein the front rib plate head 61, the rear rib plate head 62 and the connecting part 63 are the same in thickness, and the connecting part 63 is positioned between the front rib plate head 61, the rear rib plate head 62 and the connecting part 63. As can be seen from fig. 2, the sides of the front rib head 61 and the rear rib head 62 facing away from the pipe 5 are flush with the outer edges of the front flange 1 and the rear flange 2, respectively, and on the one hand are neat and attractive, and on the other hand, the front flange 1 and the rear flange 2 are supported as sufficiently as possible while saving materials.

As can be seen from fig. 2, the connecting portion 63 is provided with an arc notch, two ends of the arc notch are respectively flush with the outer edges of the front rib plate head 61 and the rear rib plate head 62, so that the connecting portion 63 at the arc notch forms an arch structure, and the structure is high in strength and small in dead weight.

The distance between the lowest point of the arc-shaped notch and the pipe 5 is smaller than the distance between the lower one of the two ends of the arc-shaped notch and the pipe 5 by 10 to 20 mm. As shown in fig. 3, the distance denoted by a is the difference in height between the lowest point of the arc-shaped notch and the end of the arc-shaped notch near the rear flange 2, and the distance denoted by b is the difference in height between the lowest point of the arc-shaped notch and the end of the arc-shaped notch near the front flange 1. Since the end of the arc-shaped gap near the front flange 1 is lower than the end near the rear flange 2, the dimension b is between 10 and 20 mm.
