Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically to a drilling hoisting device with auxiliary support. Background Technology

[0002] The core function of drilling hoisting devices is to lift and lower drill strings and casing, while controlling the drilling pressure to achieve precise control of drilling operations. In the event of accidents such as stuck drill or broken drill string, the hoisting system can respond quickly and implement emergency braking to reduce the risk of equipment damage and ensure the continuity of drilling operations. There are various types of drilling hoisting devices on the market.

[0003] However, conventional drilling hoisting devices are not convenient for auxiliary support, which may lead to instability of the support frame when the drill string is heavy. This makes it difficult to lift the drill string to different heights, and when the drill string needs to be lifted to different positions, the lifting height may not be adjustable. Furthermore, it is inconvenient to replace the drilling string, making the operation cumbersome. Therefore, we propose a drilling hoisting device with auxiliary support to solve the problems mentioned above. Utility Model Content

Currently, conventional drilling hoisting devices are not convenient for auxiliary support, which may lead to unstable support when the drill string is heavy. This makes it difficult to lift the drill string to different heights, and when the drill string needs to be lifted to different positions, the lifting height may not be adjustable. It is also inconvenient to replace the drilling string, and the operation is cumbersome when the drill string needs to be replaced.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling hoisting device with auxiliary support, comprising:

[0006] The base has a fixed hollow frame fixedly connected to its upper end, and the base has positioning grooves arranged in an array inside.

[0007] Also includes:

[0008] A rotating plate is rotatably connected to the outer sides of the left and right ends of the fixed hollow frame, and a telescopic plate is slidably connected inside the rotating plate. A first threaded rod is fixedly connected to the front end of the telescopic plate.

[0009] The first motor is fixedly connected to the upper right side of the fixed hollow frame, and a lifting structure for lifting the drill bit is provided on the outside of the first motor. The lifting structure includes a worm, a worm wheel and a rotating rod. The front end of the first motor is fixedly connected to the worm, and the upper end of the worm is meshed with the worm wheel. The left end of the worm wheel is fixedly connected to the rotating rod.

[0010] The lower end of the first motor is provided with a second threaded rod for replacing the drill bit.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the drilling hoisting device with auxiliary support can provide auxiliary support during the hoisting process of the drilling hoisting device, increase the stability of the hoisting process, can automatically hoist the drilling tools to different heights, facilitate drilling work, and can quickly change the drilling tools, making it convenient to perform different drilling operations during the drilling process;

[0018] 1. It is equipped with a base, a fixed hollow frame and a rotating plate. The fixed hollow frame is fixedly connected to the upper end of the base. The middle part of both the base and the fixed hollow frame is set to a hollow state. The rotating plate connected to the left and right sides of the fixed hollow frame is adjusted to support the two sides, which can facilitate the lifting of the drilling tools applicable during drilling.

[0019] 2. Equipped with a telescopic plate, pulleys, and positioning slots, the telescopic plate can be pulled outward or inward within the rotating plate and flipped to rotate the pulleys connected to the lower end of the telescopic plate, moving it to the inner side of the positioning slots at different positions and engaging with them. This limits the tilt angle of the rotating plate and the telescopic plate, providing auxiliary support during drilling and hoisting and preventing instability during the drilling and hoisting process.

It can adjust the support angle according to the different weights of the drill bit.

[0021] 4. It is equipped with a worm, a worm wheel, and a rotating rod. The rotation of the worm drives the worm wheel, which is meshed with the upper side of the worm, to rotate simultaneously. This causes the rotating rod, which is fixedly connected to the left end of the worm wheel, to rotate the wire rope wound on the outside, thus lifting the drill bit to different heights.

[0022] 5. It is equipped with a second threaded rod, a right clamping rod, and a left clamping rod. By rotating the second threaded rod, the left and right clamping rods, which are threaded to the left and right sides of the second threaded rod respectively, move inward or outward to position or disengage the drill bit body, which can facilitate the replacement of different drill bits for drilling operations.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 The present invention provides a technical solution: a drilling lifting device with auxiliary support, comprising a base 1, a fixed hollow frame 2, a rotating plate 3, a telescopic plate 4, a first threaded rod 5, a threaded sleeve 6, a pulley 7, a positioning groove 8, a first motor 9, a worm gear 10, a worm wheel 11, a rotating rod 12, a wire rope 13, a fixed frame 14, a second motor 15, a second threaded rod 16, a right clamping rod 17, a left clamping rod 18, and a drill body 19;

[0032] Existing drilling hoisting devices are not convenient for providing auxiliary support, which may lead to instability of the support frame when the drill string is heavy. It is also inconvenient to lift the drill string to different heights, and when the drill string needs to be lifted to different positions, the lifting height may not be adjustable. Furthermore, it is inconvenient to replace the drilling string, making the replacement process cumbersome.

[0033] The upper end of the base 1 is fixedly connected to the fixed hollow frame 2, and the left and right sides of the base 1 are provided with positioning grooves 8 in an array. The inner side of the positioning groove 8 is connected to the pulley 7. The outer side of the pulley 7 is rotatably connected to the lower end of the telescopic plate 4. The outer side of the upper end of the telescopic plate 4 is slidably connected to the inside of the rotating plate 3. The front end of the telescopic plate 4 is fixedly connected to the first threaded rod 5. The front side of the first threaded rod 5 is slidably connected to the front end of the rotating plate 3. The outer side of the first threaded rod 5 is threadedly connected to the threaded sleeve 6. The rear side of the threaded sleeve 6 is tightly fitted to the rotating plate 3.

[0034] When it is necessary to maintain the stability of the drilling hoisting device, the telescopic plate 4, which is slidably connected inside the rotating plate 3, is pulled outward or inward according to the weight of the drill string to be hoisted. This causes the first threaded rod 5, which is fixedly connected to the front end of the telescopic plate 4, to slide on the front side of the rotating plate 3. At the same time, the rotating plate 3 rotates on the outside of the fixed hollow frame 2. When the telescopic plate 4 is pulled outward, the tilt angle between the rotating plate 3 and the telescopic plate 4 increases, which can support wider drill strings. To support longer drilling tools, after adjusting the position of the telescopic plate 4, the pulley 7, which is rotatably connected inside the lower end of the telescopic plate 4, is connected to the inner side of the positioning groove 8 that conforms to the tilt angle position. The pulley 7 is limited, and the screw sleeve 6 is rotated backward so that the internal thread of the screw sleeve 6 is connected to the first threaded rod 5 until the rear side of the screw sleeve 6 is tightly fitted to the front side of the rotating plate 3. The telescopic plate 4 is positioned inside the rotating plate 3, and the support position is positioned. This can provide auxiliary support during the lifting process of the drilling hoisting device and increase the stability of the lifting process.

[0035] The upper end of the base 1 is fixedly connected to the fixed hollow frame 2, and the upper right side of the fixed hollow frame 2 is fixedly connected to the first motor 9. The front end of the first motor 9 is fixedly connected to the worm gear 10. The upper side of the worm gear 10 is meshed with the worm wheel 11, and the left end of the worm wheel 11 is fixedly connected to the rotating rod 12. The outer side of the rotating rod 12 is wound with a steel wire rope 13. The left and right sides of the rotating rod 12 are rotatably connected to the upper interior of the fixed hollow frame 2, and the lower end of the steel wire rope 13 is fixedly connected to the fixed frame 14.

[0036] When it is necessary to lift the drilling tools to different heights, the first motor 9 is started, which drives the worm gear 10 fixedly connected to the front end of the first motor 9 to rotate, and drives the worm wheel 11 meshing with the upper side of the worm gear 10 to rotate. When the worm wheel 11 rotates forward, it drives the wire rope 13 wound on the outside of the rotating rod 12 to wind up, so that the fixed frame 14 fixedly connected to the lower end of the wire rope 13 moves upward, which can drive the drilling tools to lift upward. When the worm wheel 11 rotates backward, it drives the wire rope 13 wound on the outside of the rotating rod 12 to unwind, so that the fixed frame 14 fixedly connected to the lower end of the wire rope 13 moves downward, which can drive the drilling tools to enter the well. It can automatically lift the drilling tools to different heights, which is convenient for drilling work.

[0037] The lower end of the wire rope 13 is fixedly connected to the fixing frame 14, and the right end of the fixing frame 14 is fixedly connected to the second motor 15. The left end of the second motor 15 is fixedly connected to the second threaded rod 16. The threads on the outer side of the second threaded rod 16 are arranged in opposite directions. The left thread of the second threaded rod 16 is connected to the left clamping rod 18, and the right thread of the second threaded rod 16 is connected to the right clamping rod 17. The upper sides of the right clamping rod 17 and the left clamping rod 18 are slidably connected to the inner side of the fixing frame 14. The left groove of the right clamping rod 17 is connected to the inside of the right end of the left clamping rod 18, and the lower grooves of the right clamping rod 17 and the left clamping rod 18 are connected to the inside of the upper end of the drill body 19.

[0038] When it is necessary to change the drill bit, start the second motor 15 to drive the second threaded rod 16 to rotate, causing the left clamp rod 18 and right clamp rod 17, which are threaded to the left and right sides of the second threaded rod 16 respectively, to move outward. At this time, the left side of the right clamp rod 17 disengages from the slot connection between it and the left clamp rod 18 and continues to move outward. At the same time, the upper sides of the right clamp rod 17 and the left clamp rod 18 slide outward inside the fixing frame 14 until the lower outer sides of the right clamp rod 17 and the left clamp rod 18 disengage from the slot connection between them and the drill bit body 19. Then, place any other drill bit that needs to be used on the lower outer sides of the right clamp rod 17 and the left clamp rod 18. The second motor 15 is started, which drives the second threaded rod 16 to rotate in the opposite direction, causing the right clamping rod 17 and the left clamping rod 18, which are threaded on the outside of the second threaded rod 16, to move inward. At this time, the upper inside of the right clamping rod 17 and the left clamping rod 18 moves inward inside the fixed frame 14, and the lower side of the right clamping rod 17 and the left clamping rod 18 connects with the upper inside of the other drill bit body 19 through the slot, which limits the drill bit body 19 and continues to move inward until the left side slot of the right clamping rod 17 connects with the right end of the left clamping rod 18. This allows for quick replacement of drill bits and facilitates different drilling operations during the drilling process.
