Description

Technical Field

[0001] This utility model relates to the field of drilling rig casing mounting devices, specifically a drilling rig casing mounting device. Background Technology

[0002] In the prior art, when a drilling rig is drilling, the drill rod needs to be manually moved onto the drilling rig and installed onto the power head of the drilling rig to meet the needs of the drilling operation. This operation is inconvenient. In addition, the drill rods of existing drilling rigs (such as those shown in patent CN215520763U) generally adopt a double-layer casing structure and need to be placed vertically for installation. This further increases the risk of manual operation and reduces the efficiency of installing drill rods. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a drilling rig upper pipe device, which can vertically place and position the drill rod, thereby improving the installation efficiency of the drill rod.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A casing mounting device for a drilling rig includes a base, a rotating frame, a tilting drive cylinder, a positioning bracket, a positioning drive cylinder, and a clamping mechanism. The base is fixed to the drilling rig frame. One end of the rotating frame is hinged to the base, and the other end of the rotating frame is hinged to one end of the tilting drive cylinder, while the other end of the tilting drive cylinder is hinged to the base. The positioning bracket is mounted above the rotating frame, and the positioning drive cylinder is mounted between the rotating frame and the positioning bracket. A set of clamping mechanisms is mounted at each end of the positioning bracket.

[0005] Furthermore, a first support rod and a second support rod are installed in parallel between the rotating frame and the positioning bracket. The lower end of the first support rod is hinged to the rotating frame, the upper end of the first support rod and one end of the positioning drive cylinder are hinged together to the lower part of the positioning bracket, and the lower end of the second support rod and the other end of the positioning drive cylinder are hinged together to the upper part of the rotating frame.

[0006] Furthermore, the first support rod and the second support rod are of equal length.

[0007] Furthermore, the clamping mechanism includes a clamping bracket, a first jaw, a second jaw, a first connecting rod, a second connecting rod, a transition plate, and a clamping drive cylinder; the middle portions of the first jaw and the second jaw are respectively hinged to both sides of the clamping bracket, the lower end of the first jaw is hinged to the upper end of the first connecting rod, the lower end of the second jaw is hinged to the upper end of the second connecting rod, and the lower ends of the first connecting rod and the second connecting rod are respectively hinged to the transition plate; the upper end of the clamping drive cylinder is fixedly connected to the lower part of the clamping bracket, and the lower end of the clamping drive cylinder is fixedly connected to the upper part of the transition plate.

[0008] Furthermore, the clamping bracket is equipped with a vertically movable support rod, and a support block is formed at the upper end of the support rod.

[0009] Furthermore, the support rod passes through the clamping bracket, and an adjusting nut is provided on the support rod. The adjusting nut is located on the upper and lower sides of the clamping bracket, and the adjusting nut and the support rod are threaded together.

[0010] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved: 1. In use, the two ends of the inner and outer sleeves are coaxially clamped and fixed by two sets of clamping mechanisms, and the drill rod is parallel to the positioning bracket. The flipping drive cylinder drives the rotating frame to flip 90°, so that the inner and outer sleeves are in a vertical state. At this time, the positioning drive cylinder drives the positioning bracket to move, which facilitates the connection between the inner and outer sleeves and the power head of the drilling rig, and greatly improves the installation efficiency of the drill rod.

[0011] Second, by driving the first and second support rods arranged in parallel by the positioning drive cylinder, the positioning bracket can be controlled to move in parallel relative to the rotating frame. Therefore, when the rotating frame is rotated 90°, the drill rod installed on the positioning bracket can be positioned in parallel relative to the rotating frame.

[0012] Third, by setting up the support block to hold the drill rod in place, the drill rod can be clamped more securely, thus improving the stability of the upper pipe device.

[0013] Compared with the prior art, this utility model provides a drilling rig upper pipe device that can vertically place and position the drill rod, improving the installation efficiency of the drill rod and providing better safety compared with manual operation. Attached Figure Description

[0017] Please see the appendix Figures 1 to 5 As shown, this utility model provides a drilling rig upper casing device, including a base 1, a rotating frame 2, a tilting drive cylinder 3, a positioning bracket 4, a positioning drive cylinder 5, and a clamping mechanism 6; the base 1 is used to fix it to the drilling rig frame 2000, one end of the rotating frame 2 is hinged to the base 1, the other end of the rotating frame 2 is hinged to one end of the tilting drive cylinder 3, and the other end of the tilting drive cylinder 3 is hinged to the base 1; the positioning bracket 4 is installed above the rotating frame 2, and the positioning drive cylinder 5 is installed between the rotating frame 2 and the positioning bracket 4; a set of clamping mechanisms 6 is installed at each end of the positioning bracket 4. In use, the two ends of the inner and outer sleeves are coaxially clamped and fixed by two sets of clamping mechanisms 6, and the drill rod 1000 is parallel to the positioning bracket 4. The flipping drive cylinder 3 drives the rotating frame 2 to flip 90°, so that the inner and outer sleeves are in a vertical state. At this time, the positioning drive cylinder 5 drives the positioning bracket 4 to move, which facilitates the connection between the inner and outer sleeves and the power head 3000 of the drilling rig, greatly improving the installation efficiency of the drill rod 1000.

[0018] Preferably, a first support rod 7 and a second support rod 8 are also installed parallel to each other between the rotating frame 2 and the positioning bracket 4. The lower end of the first support rod 7 is hinged to the rotating frame 2, and the upper end of the first support rod 7 and one end of the positioning drive cylinder 5 are hinged together to the lower part of the positioning bracket 4. The lower end of the second support rod 8 and the other end of the positioning drive cylinder 5 are hinged together to the upper part of the rotating frame 2. Preferably, the lengths of the first support rod 7 and the second support rod 8 are equal. By driving the parallel first support rod 7 and the second support rod 8 through the positioning drive cylinder 5, the positioning bracket 4 can be controlled to move parallel to the rotating frame 2. Therefore, when the rotating frame 2 is rotated 90°, the drill rod 1000 installed on the positioning bracket 4 can move parallel to the rotating frame 2 for positioning.

The lower ends of the first connecting rod 64 and the second connecting rod 65 are respectively hinged to the transition plate 66. The upper end of the clamping drive cylinder 67 is fixedly connected to the lower part of the clamping bracket 61, and the lower end of the clamping drive cylinder 67 is fixedly connected to the upper part of the transition plate 66. Thus, when the clamping drive cylinder 67 extends or retracts, the opening and closing of the first gripper 62 and the second gripper 63 can be controlled. Alternatively, the opening and closing of the first clamping jaw 62 and the second clamping jaw 63 can be controlled by directly hinged the two ends of the clamping drive cylinder 67 to the lower ends of the first clamping jaw 62 and the second clamping jaw 63, respectively.
