Description

Technical Field

[0001] This utility model belongs to the field of drill pipe production equipment, and in particular relates to a rapid cooling device for drill pipe production. Background Technology

[0002] Drill pipe is a core component of drilling engineering in oil and gas, geological exploration, and mining. It is essentially a hollow steel rod with threads at both ends. Its main function is to build a "bridge" between the surface equipment and the underground drill bit to realize the core functions of drilling operations.

[0003] After the existing drill pipes are machined, they need to be heat-treated (quenched and tempered) to improve their comprehensive mechanical properties. Currently, the quenching of drill pipes is mainly carried out by continuous roller hearth furnaces to achieve streamlined processing. In order to obtain martensitic or bainitic structures and improve the strength and wear resistance of the drill pipes, it is also necessary to rapidly cool the quenched drill pipes.

[0004] Currently, the main method for rapidly cooling drill pipes is to have workers use a gantry crane to quickly move the quenched drill pipes into a quenching tank, where water or quenching fluid is used to achieve rapid cooling. While this method can meet the quenching requirements of drill pipes, workers need to be in direct contact with the heated drill pipes, resulting in a poor working environment and potential safety hazards. Utility Model Content

Both the fixed rod and the movable rod include a vertical part and a gripping part arranged vertically. The gripping part is arranged in an inverted V-shape, and the movable rod is slidably disposed on the gripping frame.

[0007] Preferably, at least two gripping mechanisms are provided at intervals along the axial direction of the drill rod.

[0008] Preferably, an auxiliary rod is also provided at the bottom of the fixed rod gripping part. The auxiliary rod is horizontally arranged at the bottom of the gripping part, and the end of the auxiliary rod away from the gripping part is arranged at an angle.

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1 , Figure 2 As shown, this embodiment aims to provide a rapid cooling device for drill pipe production that can achieve automated quenching and cooling of drill pipes. To achieve the above objective, the rapid cooling device for drill pipe production provided in this embodiment includes a quenching pool 5 and a gantry frame 1 for covering the quenching pool 5 and the continuous roller hearth furnace below. In this embodiment, considering that the quenching and cooling time is generally between 30s and 1min, the span of the gantry frame 1 is larger. Its purpose is to add a drill pipe placement rack on the other side of the quenching pool 5 to complete the three actions of quenching, cooling, and placement.

[0017] Considering that the cooling work is mainly accomplished by quenching fluid, the human element needs to be addressed, which means achieving automated movement. Therefore, in this embodiment, a movable frame 2 is provided on the top of the gantry frame 1. The movable frame 2 is slidably mounted on the top of the gantry frame 1. There are various ways to drive the movable frame 2. For example, a motor can be installed on the movable frame 2 and a rack can be installed on the gantry frame 1. Movement can be achieved by the motor cooperating with the gears and rack. Of course, a motor and a chain can also be used to achieve the reciprocating motion of the movable frame 2. This is an existing mature technical solution, so it will not be described in detail in this embodiment.

[0018] A gripping frame 3 is provided below the movable frame 2. The gripping frame 3 is raised and lowered below the movable frame 2. In this embodiment, the gripping frame 3 is generally arranged in the shape of a cuboid box. A lifting cylinder 21 is provided on the movable frame 2. The power end of the lifting cylinder 21 is connected to the gripping frame 3, thus realizing the raising and lowering of the gripping frame 3.

[0019] To enable gripping of the drill pipe, gripping mechanisms 4 are provided on the gripping frame 3. Considering the relatively long length of the drill pipe, the gripping mechanisms 4 are spaced apart on the gripping frame 3, with at least two gripping mechanisms 4 spaced apart along the axial direction of the drill pipe. In this embodiment, four gripping mechanisms 4 are provided to ensure gripping stability.

[0020] To achieve rapid gripping, in this embodiment, the gripping mechanism 4 includes a fixed rod 41 fixed to the bottom of the gripping frame 3 and a movable rod 42 that is staggered with the fixed rod 41. Both the fixed rod 41 and the movable rod 42 include a vertical part 43 and a gripping part 44 arranged vertically. The gripping part 44 is arranged in an inverted V-shape. In this embodiment, the gripping part 44 is arranged in an inverted V-shape mainly because the drill rod is mainly cylindrical or polygonal, and the inverted V-shape can ensure effective gripping.

[0021] The staggered arrangement of the fixed rod 41 and the movable rod 42 changes the clamping method to a stacking method. If the movable rod 42 and the fixed rod 41 are set opposite each other, it will clamp the drill rod. Since the drill rod is a cylindrical structure, it is difficult to clamp. By stacking the drill rod in the space formed by the movable rod 42 and the fixed rod 41, it can be effectively fixed.

[0022] Of course, the movable rod 42 is slidably mounted on the gripping frame 3. In this embodiment, the vertical part 43 of the movable rod 42 extends into the top of the gripping frame 3. The gripping frame 3 is provided with a movable hole 31, which is a rectangular slot to meet the movement requirements of the movable rod 42. At the same time, a pushing cylinder 46 is provided on the gripping frame 3, and the power end of the pushing cylinder 46 is connected to the vertical part 43 of the movable rod 42. In this way, the pushing of the movable rod 42 is realized.

[0023] To ensure the stability of the moving rod 42 during pushing, a guide shaft 421 is provided on the vertical part 43 of the moving rod 42, and a linear bearing 33 that mates with the guide shaft 421 is provided on the gripping frame 3. A guide hole 32 is provided on the gripping frame 3, and the linear bearing 33 is installed in the guide hole 32. This ensures the stability of the moving rod 42 during operation.

[0024] To ensure the stability of the drill rod fixation, an auxiliary rod 45 is also provided at the bottom of the gripping part 44 of the fixed rod 41. The auxiliary rod 45 is horizontally set at the bottom of the gripping part 44, and the end of the auxiliary rod 45 away from the gripping part 44 is set at an angle. Since the conveying mechanism of the continuous roller hearth furnace is roller conveying, there is a gap at the bottom. The bottom of the fixed rod 41 and the movable rod 42 can be controlled below the drill rod by the lifting mechanism. Then, the movable rod 42 moves to achieve the stacking and fixing.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
