Description

Technical Field

[0001] This utility model relates to the field of roller cone drill bit painting fixtures, and in particular to a roller cone drill bit painting suspension device. Background Technology

[0002] Tricone drill bits, due to their small thread face, center of gravity close to the cone, and heavy weight, must be placed with the cone facing down during handling and storage. However, during the rust-proofing and painting process for tricone drill bits, since the threads do not require painting, the drill bit must be flipped so that the cone is facing up and the thread is facing down on a pad on the roller conveyor before being pushed into the paint booth. After painting, the drill bit needs to be flipped again to be packaged in the correct orientation (thread up). Because this operation is generally performed on the roller conveyor, it poses a significant safety risk. Summary of the Invention

[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model discloses a roller cone drill bit painting suspension device.

[0004] Technical solution: The roller cone drill bit painting suspension device disclosed in this utility model has a pad on the roller conveyor logistics line, a hanger on the pad, a horizontal hanging plate on the hanger, a lifting rod on the horizontal hanging plate, and the lifting rod extending downward and connected to the lifting plate;

[0005] The inner wall of the threaded portion of the roller cone drill bit is machined with a retaining ring groove. The lifting plate extends to the inner side of the threaded portion and is fixed to the retaining ring groove by the retaining ring, thereby upper-limiting the lifting plate so that the roller cone drill bit is hung upside down on the horizontal hanging plate by the lifting rod and transported on the roller conveyor logistics line.

[0006] Furthermore, the hanger includes two columns and a top-connected crossbeam, and the horizontal hanging plate is fixed to the crossbeam.

[0007] Furthermore, a hanging hole is provided on the horizontal hanging plate, and the hanging hole extends outward to form an outwardly expanding guide notch, the inner size of the guide notch being smaller than the diameter of the hanging hole;

[0008] The lifting rod consists of a first rod body, a second rod body, and a third rod body from top to bottom. The diameter of the first rod body is larger than the diameter of the hanging hole. The diameter of the second rod body is larger than the inner opening of the guide notch but smaller than the diameter of the hanging hole. The diameter of the third rod body is smaller than the inner opening of the guide notch. The third rod body is inserted into the hanging hole by moving it horizontally. The second rod body is then moved downwards until it is positioned inside the hanging hole, until the bottom of the first rod body rests on the upper edge of the hanging hole.

[0009] Furthermore, the second and third rods are connected by a conical rod.

[0010] Furthermore, the bottom center of the lifting plate is fixed to the bottom of the third rod by a screw passing through it, and the screw and the lifting plate are in clearance fit, allowing them to rotate circumferentially.

[0011] Furthermore, a lifting ring is fixed to the top of the lifting rod.

[0012] Beneficial effects: Compared with the prior art, the advantages of this utility model are as follows: This device can directly lift the roller cone drill bit from the ground and hang it on the frame with the thread facing upward, so that the roller cone and the pad are separated to facilitate all-round painting of the roller cone. After the paint dries, the drill bit can be directly hoisted into the packaging box, reducing the number of flipping operations, effectively reducing safety risks, and also simplifying the operation process and improving work efficiency.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-5 The roller cone drill bit painting suspension device shown has a pad 2 on the roller feed line 1, a hanger 3 on the pad 2, a horizontal hanging plate 4 on the hanger 3, a lifting rod 5 on the horizontal hanging plate 4, and the lifting rod 5 extends downward and is connected to a lifting plate 6.

[0020] The inner wall of the threaded portion of the roller cone drill bit is machined with a retaining ring groove. The lifting plate 6 extends to the inner side of the threaded portion and is fixed to the retaining ring groove by the retaining ring 7, thereby upper-limiting the lifting plate 6 so that the roller cone drill bit is hung upside down on the horizontal hanging plate 4 by the lifting rod 5 and transported on the roller conveyor 1.

[0021] The hanger 3 includes two columns 301 and a top-connected crossbeam 302, and the horizontal hanging plate 4 is bolted to the middle of the crossbeam 302.

[0022] The horizontal hanging plate 4 has a hanging hole 401, which extends outward to form an outwardly expanding guide notch 402. The inner size of the guide notch 402 is smaller than the diameter of the hanging hole 401.

[0023] The lifting rod 5 consists of a first rod body 501, a second rod body 502, and a third rod body 503 from top to bottom. The diameter of the first rod body 501 is larger than the diameter of the hanging hole 401. The diameter of the second rod body 502 is larger than the inner opening of the guide notch 402 but smaller than the diameter of the hanging hole 401. The diameter of the third rod body 503 is smaller than the inner opening of the guide notch 402. The third rod body 503 is moved laterally into the hanging hole 401 and then moved downwards to position the second rod body 502 inside the hanging hole 401 until the bottom of the first rod body 501 rests on the upper edge of the hanging hole 401.

[0024] The second rod 502 and the third rod 503 are connected by a conical rod 504, which allows the second rod 502 to smoothly enter the hanging hole 401.

[0025] The bottom center of the lifting plate 6 is fixed to the bottom of the third rod 503 by a screw 506 passing through it. The screw 506 and the lifting plate 6 are in clearance fit to ensure that the roller cone drill bit is in a vertical position during hoisting, and the lifting plate can rotate around the screw, which makes it easy to rotate the drill bit during the painting process.

[0026] The top of the lifting rod 5 is fixed with a lifting ring 505 for easy suspension.

[0027] After the lifting plate 6 is bolted and fixed by the third rod 503, it is placed inside the threaded part of the roller cone drill bit, with its position lower than the groove of the retaining ring. The retaining ring 7 is fixed in the groove of the retaining ring to limit the lifting plate 6 upward, so that the roller cone drill bit can be lifted smoothly. After the third rod 503 enters through the guide notch 402, it descends so that the second rod 502 is located in the hanging hole 401, forming a horizontal limit. It continues to descend until the bottom of the first rod 501 is placed on the hanging hole 401, forming a downward limit. The roller cone drill bit is directly lifted from the ground and suspended on the frame with the thread facing upward. This leaves a distance between the roller cone and the pad to facilitate all-round painting of the roller cone. After the paint dries, the drill bit can be directly hoisted into the packaging box, which can reduce the number of flipping operations, effectively reduce safety risks, simplify the operation process, and improve work efficiency.
