Description

Technical Field

[0001] This utility model relates to the field of oil drilling equipment technology, specifically an adjustable hydraulic tongs fixing bracket for oil drilling rigs. Background Technology

[0002] In oil drilling operations, hydraulic tongs are key tools used to tighten or loosen drill pipe joints. However, after use, hydraulic tongs need to be stored away, and current traditional storage methods, such as using ordinary shelves, have many limitations.

[0003] Ordinary shelves cannot be adjusted in height and angle to suit actual work needs, limiting the flexibility of using hydraulic shears. Workers need to move frequently to place the hydraulic shears evenly on the shelves, which not only wastes time and effort but also increases physical exertion and reduces work efficiency.

[0004] Meanwhile, traditional shelving is not adaptable when placing hydraulic shears, as its height cannot be adjusted, making it difficult to accommodate the height of workers and complex working environments, resulting in inconvenience in operation and increasing safety hazards. Utility Model Content

[0005] The purpose of this utility model is to make up for the shortcomings of the existing technology and to provide an adjustable hydraulic tongs fixing bracket for oil drilling rigs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hydraulic tong fixing frame for oil drilling rigs, comprising three placement circular plates, which are fixedly connected by two connecting cross ribs. Each placement circular plate has a set of placement holes inside. A fixing circular plate is provided below each placement circular plate, and a fixing hole is provided inside the fixing circular plate. A rotating mechanism and a lifting mechanism are provided between the placement circular plates and the fixing circular plates. The rotating mechanism includes a circular shell fixedly connected to the upper surface of the fixing circular plate, and a rotating column is rotatably connected inside the circular shell. The lifting mechanism includes a cylindrical body fixedly connected to the top of the rotating column, and a limiting square hole is provided inside the cylindrical body. A threaded square tube is slidably connected inside the limiting square hole, and the threaded square tube is fixedly connected to the bottom surface of the placement circular plate.

[0007] Preferably, a first motor is fixedly installed on the inner bottom wall of the circular shell, and a rotating shaft is fixedly installed on the output end of the first motor.

[0008] Preferably, a first gear is fixedly connected to the top end of the rotating shaft, and a second gear meshes with the outer surface of the first gear.

[0009] Preferably, the second gear is fixedly connected to the outer surface of the rotating column to ensure the stability and reliability of the rotating mechanism, thereby precisely controlling the rotation angle of the placed circular plate to meet the needs of different working scenarios.

[0010] Preferably, a second motor is fixedly installed on the inner bottom wall of the cylindrical body, and a lead screw is fixedly installed on the output end of the second motor.

[0011] Preferably, the lead screw is connected to the internal thread of the threaded square tube to provide stable lifting power, ensuring the smoothness and accuracy of the lifting process, and making the placement and adjustment of the hydraulic clamp more convenient and efficient.

[0012] Beneficial effects:

[0013] Compared with existing technologies, this adjustable hydraulic tongs holder for oil drilling rigs has the following advantages:

[0014] I. This utility model solves the problem of traditional shelves being unable to adjust height and angle by setting up a rotating mechanism and a lifting mechanism. The rotating mechanism achieves angle adjustment of the placed circular plate through a first motor and gear transmission, while the lifting mechanism achieves height adjustment of the placed circular plate through a second motor and screw transmission. This design can flexibly adjust the placement position of the hydraulic clamp according to the height of the staff and the needs of the actual work scene, avoiding the inconvenience and safety hazards caused by the fixed height and angle of traditional shelves, and significantly improving the convenience of operation and work efficiency.

[0015] Second, this utility model ensures the stability of the overall structure through the structural design of three placement circular plates and connecting cross rib plates. At the same time, in conjunction with the rotation function of the rotating mechanism, it achieves efficient storage of hydraulic pliers. The operator can sit in one position and use the rotating mechanism to evenly place multiple hydraulic pliers in the placement holes without frequent movement, reducing physical exertion and improving storage efficiency. In addition, the fixed circular plates are stably installed in the working position through the fixed holes, further ensuring the stability of the fixing frame during use and ensuring reliable storage of the hydraulic pliers.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] See Figures 1-4 An adjustable hydraulic clamp holder for an oil drilling rig includes three placement circular plates 1, which are fixedly connected by two connecting cross ribs 3. Each placement circular plate 1 has a set of placement holes 2 inside. A fixing circular plate 4 is provided below the placement circular plate 1, and the fixing circular plate 4 has fixing holes 7 inside.

[0023] There are three placement circular plates 1, each with a set of placement holes 2 for placing hydraulic clamps. They are connected to each other by two connecting cross ribs 3 to ensure the overall structural stability. The fixing circular plate 4 is located below the placement circular plates 1, and its internal fixing holes 7 can be used to install the fixing bracket in the working position to ensure operational stability.

[0024] A rotating mechanism 5 and a lifting mechanism 6 are provided between the placing circular plate 1 and the fixed circular plate 4. The rotating mechanism 5 includes a circular shell 501 fixedly connected to the upper surface of the fixed circular plate 4, and a rotating column 503 rotatably connected inside the circular shell 501. The lifting mechanism 6 includes a cylindrical body 601 fixedly connected to the top of the rotating column 503. A limiting square hole 605 is opened inside the cylindrical body 601, and a threaded square tube 604 is slidably connected inside the limiting square hole 605. The threaded square tube 604 is fixedly connected to the bottom surface of the placing circular plate 1. A first motor 502 is fixedly installed on the inner bottom wall of the circular shell 501, and a rotating shaft 505 is fixedly installed at the output end of the first motor 502. A first gear 506 is fixedly connected to the top of the rotating shaft 505, and a second gear 504 meshes with the outer surface of the first gear 506. The second gear 504 is fixedly connected to the outer surface of the rotating column 503 to ensure the stability and reliability of the rotating mechanism, thereby precisely controlling the rotation angle of the placing circular plate to meet the needs of different working scenarios. A second motor 602 is fixedly installed on the inner bottom wall of the cylindrical body 601, and a lead screw 603 is fixedly installed on the output end of the second motor 602. The lead screw 603 is connected to the internal thread of the threaded square tube 604 to provide stable lifting power, ensure the smoothness and accuracy of the lifting process, and make the placement and adjustment of the hydraulic clamp more convenient and efficient.

[0025] The rotating mechanism 5 includes a circular housing 501 fixed to the upper surface of the fixed circular plate 4. A rotating column 503 is rotatably connected inside the circular housing 501. The first motor 502, rotating shaft 505, first gear 506, and second gear 504 inside work together to adjust the angle of the placed circular plate 1. The cylindrical body 601 of the lifting mechanism 6 is fixed to the top of the rotating column 503. The limiting square hole 605 inside is slidably connected to the threaded square cylinder 604. In conjunction with the second motor 602 and the lead screw 603, the height of the placed circular plate 1 is adjusted.

[0026] See Figures 1-4 In some practical applications, the entire mounting frame is first installed in a suitable position using the fixing holes 7 of the fixed circular plate 4, depending on the work site conditions. When hydraulic pliers need to be placed, if the height of the worker or the work environment requires adjustment, the second motor 602 inside the cylindrical body 601 is activated. The lead screw 603 rotates, causing the threaded square cylinder 604 to move up and down within the limiting square hole 605, thereby adjusting the height of the placement circular plate 1. If the placement angle needs to be adjusted, the first motor 502 inside the circular housing 501 is activated, causing the rotating column 503 to rotate through gear transmission, thus rotating the placement circular plate 1 to a suitable angle. Afterward, the worker inserts the cylindrical handle of the hydraulic pliers into the placement hole 2 of the placement circular plate 1 for storage. When placing multiple hydraulic pliers, they can be evenly placed in one location by using the rotating mechanism 5, greatly improving work efficiency.

[0027] Working principle: When the height of the fixed frame needs to be adjusted, the second motor 602 on the bottom wall of the inner cylinder 601 is activated. The output end of the second motor 602 drives the lead screw 603 to rotate. Since the lead screw 603 is threadedly connected to the inside of the threaded square cylinder 604, and the threaded square cylinder 604 can only slide up and down within the limiting square hole 605, it cannot rotate. As the lead screw 603 rotates, the threaded square cylinder 604 moves up and down within the limiting square hole 605, thereby driving the placement circular plate 1, which is fixedly connected to the threaded square cylinder 604, to rise and fall. In this way, the height of the placement circular plate 1 can be conveniently and accurately adjusted according to the height of the worker and the needs of the actual work scenario, making the placement and retrieval of the hydraulic clamp more convenient, reducing the difficulty of operation, improving work efficiency, and reducing safety hazards caused by unsuitable height.

[0028] When the angle of the fixing frame needs to be adjusted, the first motor 502 on the bottom wall of the inner wall of the cylindrical housing 501 is activated. The output end of the first motor 502 drives the rotating shaft 505 to rotate, and the first gear 506 at the top of the rotating shaft 505 rotates accordingly. Since the outer surfaces of the first gear 506 and the second gear 504 mesh, the rotation of the first gear 506 will drive the second gear 504 to rotate. The second gear 504 is fixedly connected to the outer surface of the rotating column 503, so the rotating column 503 will rotate accordingly. When the rotating column 503 rotates, the cylindrical body 601 fixed at its top and the placement circular plate 1 connected to the cylindrical body 601 will rotate together around the axis of the rotating column 503, thereby realizing the adjustment of the angle of the placement circular plate 1. By precisely controlling the rotation angle of the first motor 502, the placement circular plate 1 can be made to reach the required angle, meeting the diverse needs for the placement angle of the hydraulic clamp in different working scenarios and improving the flexibility of the fixing frame.

[0029] When storing hydraulic shears, workers can place them into the placement holes 2 inside the placement circular plate 1. Specifically, this is done by inserting the two cylindrical handles of the hydraulic shears into the two placement holes 2. When storing multiple hydraulic shears, in conjunction with the rotating mechanism 5, the worker can sit in one position and evenly place many hydraulic shears into the placement holes 2 inside the placement circular plate 1, thus achieving simple and practical storage. Because the fixing circular plate 4 has fixing holes 7 inside, the entire fixing frame can be stably installed in the required working position through the fixing holes 7, ensuring the stability of the fixing frame during use. The three placement circular plates 1 are fixedly connected by two connecting cross ribs 3, ensuring the stability of the entire fixing frame structure, enabling it to bear the weight of the hydraulic shears and remain stable during adjustment.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
