Description

Technical Field

[0001] The utility model belongs to the technical field of oil casing, and in particular relates to a tungsten alloy coated oil casing with anti-bite marks of forceps. Background Art

[0002] Oil casing generally refers to pipeline equipment used in oil drilling or transportation. It is usually made of steel pipe or other alloy materials and is used to transport crude oil, natural gas or other liquid products. Oil casing plays an important role in the oil industry. Depending on the specific usage scenarios and requirements, oil casing may need to have high pressure resistance, corrosion resistance, wear resistance and other characteristics. Tungsten alloy coated oil casing may be an improved oil casing designed for specific working conditions, with higher wear resistance and durability.

[0003] In the prior art, when installing the oil casing, it may be necessary to place the oil casing vertically and then install it through the flange. In order to ensure the stable installation of the oil casing, a crane is usually used to lift the oil casing. However, during the lifting period, the crane and the oil casing need to be fixed to prevent the oil casing from falling off during the lifting period. The process of fixing the crane and the oil casing requires the use of a caliper, but this fixing method is not only unstable and easy to cause the oil casing to fall off in the air, but also during the lifting period, the caliper will rub against the surface of the oil casing, thereby causing bite marks or scratches on the surface of the oil casing. For this reason, we propose a tungsten alloy coated oil casing that is resistant to bite marks of pliers to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 The utility model provides a tungsten alloy coated oil casing with resistance to jaw bite marks, which is characterized by comprising a connecting assembly 1, a clamping assembly 3 for connecting with a crane is installed on the connecting assembly 1, a driving assembly 4 is installed in the connecting assembly 1, and the oil casing 2 is installed above the driving assembly 4 inside the connecting assembly 1;

[0026] The connection assembly 1 includes a connection member 12, a rotating arm 13, a stopper 14 and a rotating shaft 15. The rotating arm 13, the stopper 14 and the rotating shaft 15 are all provided in plurality. The connection member 12 is provided with a plurality of placement grooves 16 circumferentially around the oil casing 2. The plurality of rotating shafts 15 are respectively installed in the plurality of placement grooves 16. The plurality of rotating arms 13 are respectively connected to the rotating shafts 15 and extend out of the connection member 12. The plurality of stoppers 14 are respectively fixed to one end of the rotating arm 13.

[0027] The driving assembly 4 includes a pulling rod 41 and an extrusion piece 42. There are multiple extrusion pieces 42. The pulling rod 41 is arranged inside the connecting assembly 1. The multiple extrusion pieces 42 are fixedly connected to the surface of the pulling rod 41. The multiple extrusion pieces 42 are respectively slidably connected to one end of the rotating arm 13.

[0028] Specifically, when the oil casing 2 is fixed, in order to enable it to be lifted by the crane more stably, the oil casing 2 can be clamped by the connecting component 1 during the lifting, and then the connecting component 1 is connected to the crane through the clamping component 3, so that the oil casing 2 can be stably lifted. During use, in order to be able to control whether the connecting component 1 is clamped to the oil casing 2, a driving component 4 can be set inside the connecting component 1, and the driving component 4 can be used to control whether the connecting component 1 is clamped to the oil casing 2.

[0029] Furthermore, during use, when the oil casing 2 needs to be lifted, the pulling rod 41 can be pulled to drive the extrusion member 42 to move downward. Since the extrusion member 42 is slidably connected to one end of the rotating arm 13, and the rotating arm 13 is arranged on the surface of the rotating shaft 15, the rotating shaft 15 is rotatably connected to the inside of the placement groove 16, and the stopper 14 is fixedly connected to one end of the rotating arm 13, when the extrusion member 42 moves downward, it will drive the rotating arm 13 to rotate around the rotating shaft 15. At this time, since the stopper 14 is arranged on the surface of the rotating shaft 15, the rotating arm 13 can rotate downward. One side end of the rotating arm 13, so at this time the limit piece 14 will move inward, because the pull rod 41 is provided with three groups of extrusion members 42, and the rotating arm 13, the limit piece 14, and the rotating shaft 15 are also provided with three groups, so during use, when the pull rod 41 moves downward, it will drive the three groups of rotating arms 13, the limit piece 14 and the rotating shaft 15 to rotate at the same time, so that the three groups of limit pieces 14 can be brought close to each other, and at this time the oil casing 2 can be clamped by the limit piece 14, so that the oil casing 2 can be stably installed.

[0030] In this embodiment, the connecting assembly 1 further includes a hollow main body 11 , the hollow main body 11 is fixedly connected to the lower end of the connecting member 12 , and the pulling rod 41 is slidably connected to the inside of the hollow main body 11 .

[0031] Specifically, during specific use, in order to be able to set the pulling rod 41 and the connecting member 12 more stably, the connecting member 12 can be fixedly connected to the upper end of the hollow main body 11, and because the hollow main body 11 is hollow inside, the pulling rod 41 is slidably connected to the inside of the hollow main body 11, so that when the oil casing 2 is subsequently installed, the pulling rod 41 can be pulled to drive the limiting member 14 to limit the oil casing 2.

[0032] In this embodiment, the driving assembly 4 further includes a spring 43 . A plurality of springs 43 are provided, and the plurality of springs 43 are all installed between the extrusion member 42 and the hollow main body member 11 .

[0033] Specifically, in actual use, after the oil casing 2 is lifted and installed, it is necessary to release the limit of the oil casing 2 by the limit member 14. In order to quickly release the limit of the oil casing 2 by the limit member 14, three groups of springs 43 can be set between the upper end of the hollow main body 11 and the lower end of the extrusion member 42. When the oil casing 2 is limited, the extrusion member 42 moves downward to squeeze the spring 43. When the limit needs to be released, it is only necessary to release the pull on the pull rod 41, and the elastic force of the spring 43 can make the pull rod 41 and the extrusion member 42 move upward, so that the three groups of limit members 14 return to their original positions, thereby releasing the limit on the oil casing 2.

[0034] In this embodiment, the oil casing 2 includes a flange 21 and a pipe body 22 . The pipe body 22 is installed on the upper end of the flange 21 , and the flange 21 is disposed between the plurality of rotating arms 13 .

[0035] Specifically, when limiting the position of the oil casing 2, in order to enable the oil casing 2 to maintain its own stability during the lifting, a flange 21 can be installed at one end of the pipe body 22, and the flange 21 is set between the three sets of rotating arms 13. At this time, the oil casing 2 can be limited by pulling the pulling rod 41. When the pulling rod 41 is pulled, the limiting member 14 will clamp the surface of the pipe body 22 and the lower end protruding part of the limiting member 14 will clamp the flange 21. Through double clamping, the oil casing 2 can be stably lifted.

[0036] In this embodiment, the clamping assembly 3 includes a threaded ring 31 , and the threaded ring 31 is threadedly connected to the pulling rod 41 .

[0037] Specifically, when connecting the connecting assembly 1 to the crane, in order to enable a detachable connection between the two, so that the limit on the oil casing 2 can be quickly released later, a threaded structure can be set on the lower end surface of the pull rod 41, and then the threaded connection between the pull rod 41 and the threaded ring 31 is connected, and then the threaded ring 31 is connected to the crane, so that the crane can be stably connected to the connecting assembly 1 at this time.

[0038] In this embodiment, the clamping assembly 3 further includes a ratchet 32 ​​and ratchet teeth 33. The ratchet 32 ​​is fixedly connected to the surface of the threaded ring 31, and the ratchet teeth 33 are installed at the lower end of the hollow main body 11. The ratchet 32 ​​and the ratchet teeth 33 are clamped.

[0039] Specifically, during use, in order to prevent the threaded ring 31 from deflecting in the opposite direction when the oil casing 2 is lifted, thereby causing the crane to disengage from the connecting assembly 1, the ratchet 32 ​​can be fixedly connected to the surface of the threaded ring 31, and then the ratchet 33 can be installed at the lower end of the hollow main body 11, the threaded ring 31 is threadedly connected to the pull rod 41, and the ratchet 32 ​​is clamped with the ratchet 33. At this time, the clamping of the ratchet 33 can prevent the threaded ring 31 and the ratchet 32 ​​from deflecting in the opposite direction, thereby causing the threaded ring 31 and the pull rod 41 to disengage, and then causing the connecting assembly 1 to disengage from the crane.

[0040] In this embodiment, the inner diameter of the stopper 14 is the same as the outer diameter of the tube body 22 , and the outer diameter of the flange 21 is greater than the outer diameter of the tube body 22 .

[0041] Specifically, when the tube body 22 is clamped, in order to enable the limiting member 14 to fit more closely to the surface of the tube body 22 and thus improve the clamping effect, the inner diameter of the limiting member 14 can be set to be the same as the outer diameter of the tube body 22, and in order to enable the lower end of the limiting member 14 to be clamped to the flange 21, the outer diameter of the flange 21 is set to be larger than the outer diameter of the tube body 22.

[0042] The working principle and use process of the utility model are as follows: when the oil casing 2 is longitudinally installed, the connecting component 1 and the crane can be connected by the clamping component 3, and the ratchet 32 ​​can be clamped by the ratchet 33, so that the threaded ring 31 can be stably connected with the pulling rod 41 at this time, and then the connecting component 1 can be moved above the oil casing 2 and the crane can be started. When the crane is started, the threaded ring 31 will pull the pulling rod 41 to move, and then the rotating arm 13 and the limiting member 14 can be driven to rotate. The oil casing 2 can be limited by the limiting member 14 at this time. After it is fully limited, the oil casing 2 can be lifted, and it is relatively stable during the lifting period and is not easy to fall off.

[0043] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
