Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling and production pipe racks, and specifically relates to an adjustable drill pipe rack for oil drilling and production. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons with natural occurrence. Petroleum is further divided into crude oil, natural gas, natural gas liquids, and natural tar, etc. However, conventionally, "petroleum" is still used as the definition of "crude oil". Petroleum is a viscous, dark brown liquid and is called the "blood of industry". There is petroleum storage in some areas of the upper crust. Its main components are mixtures of various alkanes, cycloalkanes, and aromatic hydrocarbons.

[0003] After retrieval, it is found that the Chinese patent with the application number 202223062918.8 discloses an adjustable drill pipe rack for oil drilling and production, including a triangular pipe rack. An adjusting mechanism for conveniently adjusting and fixing the oil pipeline drilling and production is arranged on the outer surface of the triangular pipe rack, and a stabilizing mechanism for maintaining stable support is arranged on the lower surface of the triangular pipe rack; the adjusting mechanism includes three sliding sleeves slidably connected to the outer surface of the triangular pipe rack. Connecting rods are fixed between the opposite sides of the three sliding sleeves. One ends of the three connecting rods facing each other are fixed with a fixed sleeve. Three adjusting screw holes are formed in the inner peripheral wall of the fixed sleeve. Adjusting screws are threadedly connected to the inner peripheral walls of the three adjusting screw holes. One ends of the three adjusting screws facing each other are fixed with a fixing plate, and fixing holes are formed in the outer surface of the triangular pipe rack.

[0004] The above-mentioned utility model has the following problems:

[0005] 1. When it is necessary to clamp and fix the oil pipeline in the above-mentioned comparative document, it is necessary to rotate three groups of adjusting screws. The adjusting screws drive the fixing plate to clamp. Each group of screws needs to be adjusted one by one to ensure that the fixing plate clamps the pipeline evenly. It takes a lot of time. Moreover, if the rotation of the three groups of adjusting screws is uneven or the adjustment is inaccurate, the fixing plate may apply uneven clamping forces at different positions, which may cause deformation or damage to the oil pipeline, especially serious under high pressure or long-term loading conditions.

[0006] Therefore, those skilled in the art have provided an adjustable drill pipe rack for oil drilling and production to solve the problems raised in the above background art. Content of the Utility Model

[0007] The purpose of the present utility model is to provide an adjustable drill pipe rack for oil drilling and production to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] An adjustable drill pipe rack for oil drilling and production, comprising a fixing plate. At the four corners of the lower end of the fixing plate, telescopic rods are fixedly connected. At the lower ends of the telescopic rods, mounting plates are fixedly connected. At the lower end of the mounting plate, fixed insertion rods are fixedly connected. At the upper end of the fixing plate, a fixed bracket is fixedly connected.

[0010] As a further solution of the present utility model: A fixed ring is fixedly connected to the upper side of the fixed bracket. A fixed block is fixedly connected to the inner wall of one side of the fixing plate. Rotating clamping jaws are rotatably connected to both sides of the fixed block. A lead screw is threadedly connected through one side of the fixed block and the fixing plate.

[0011] As a further solution of the present utility model: One end of the lead screw is fixedly connected with a rotating grip. The other end of the lead screw is rotatably connected with an adjusting block. Guide rods are fixedly connected to both sides of the adjusting block. Guide grooves are respectively formed on the inner sides of the rotating clamping jaws. The guide rods are slidably connected to the guide grooves.

[0012] As a further solution of the present utility model: Clamping blocks are fixedly connected to one side of the two groups of rotating clamping jaws and the adjusting block. A plurality of springs are fixedly connected to the inner side of the fixed ring. The springs are defaulted to be elastic springs. The other end of the spring is fixedly connected with an auxiliary clamping plate.

[0013] As a further solution of the present utility model: An adjusting groove is formed near the upper side of the telescopic rod. An adjusting bolt is threadedly connected to the lower side of the telescopic rod. And the adjusting groove and the adjusting bolt are used in cooperation with each other. A counterweight basket is fixedly connected between the two mounting plates.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. The rotating grip drives the adjusting block to adjust the clamping force through a single rotation action. Compared with the need to adjust three groups of adjusting screws one by one, the operation is more convenient and fast. The adjusting block and the rotating clamping jaws driven by the rotating grip can provide a more uniform clamping force. Compared with the adjusting screws, which may cause uneven clamping force due to inaccurate manual operation, it can ensure that the pipeline is clamped evenly and stably. The rotating grip and the adjusting block are more flexible and applicable to pipelines of different diameters. Using the rotating grip and the adjusting block to clamp the oil pipeline compared with the method of three groups of adjusting screws, not only the operation is more convenient and fast, but also higher clamping accuracy and uniformity can be provided.

The lower end of the mounting plate 3 is fixedly connected with a fixed insertion rod 4. The upper end of the fixed plate 1 is fixedly connected with a fixed bracket 5. The upper side of the fixed bracket 5 is fixedly connected with a fixed ring 6. One inner wall of the fixed plate 1 is fixedly connected with a fixed block 7. On both sides of the fixed block 7, rotating clamping jaws 8 are rotatably connected. A lead screw 9 is threadedly connected through one side of the fixed block 7 and the fixed plate 1. One end of the lead screw 9 is fixedly connected with a rotating grip 11. The other end of the lead screw 9 is rotatably connected with an adjusting block 10. On both sides of the adjusting block 10, guiding rods 13 are fixedly connected. Guiding grooves 12 are respectively opened on the inner sides of the rotating clamping jaws 8. The guiding rods 13 are slidably connected in the guiding grooves 12. On one side of the two groups of rotating clamping jaws 8 and the adjusting block 10, clamping blocks 14 are fixedly connected. By placing the mounting plate on the ground and inserting the fixed insertion rod into the soil for fixation, the oil pipeline is placed inside the fixed plate through the fixed ring and then into the soil. Then, the rotating grip is rotated. The rotating grip drives the adjusting block to move. The guiding rods of the adjusting block move in the guiding grooves on the inner sides of the rotating clamping jaws, causing the rotating clamping jaws to approach the oil pipeline. The clamping blocks fixedly connected to the adjusting block and the rotating clamping jaws clamp and fix the oil pipeline to prevent the oil pipeline from moving during operation.

[0024] It should be added that the clamping block 14 is made of rubber, which can increase friction to achieve an anti-slip effect and at the same time reduce the wear generated on the contact surface with the pipeline.

[0025] Embodiment 2

[0026] Refer to Figure 1 、 3 、4. This embodiment is based on the previous embodiment. The difference from the previous embodiment is that multiple groups of springs 15 are fixedly connected to the inner side of the fixed ring 6. The springs 15 are defaulted to be elastic springs. The other end of the spring 15 is fixedly connected with an auxiliary clamping plate 16. An adjustment groove 17 is opened near the upper side of the telescopic rod 2. A adjusting bolt 18 is threadedly connected to the telescopic rod 2 near the lower side, and the adjustment groove 17 and the adjusting bolt 18 are used in cooperation with each other. A counterweight basket 19 is fixedly connected between the two mounting plates 3; when the oil pipeline passes through the auxiliary clamping plate inside the fixed ring, the spring adjusts the auxiliary clamping plate, so that the auxiliary clamping plate assists in clamping the oil pipeline. When it is necessary to adjust the clamping position of the oil pipeline, it is adjusted by adjusting the telescopic rod. The adjusting bolt and the adjustment groove cooperate with each other to fix the height of the telescopic rod. When encountering bad weather, the stability of the adjustable drill pipe rack for oil drilling can be increased by putting stones or counterweight blocks into the counterweight basket.
