Technical Field
[0001] The utility model relates to the technical field of slip hangers, in particular to a new type of multifunctional combined integrated slip hanger. Background Technique
[0002] A slip hanger is a device used to hang casing pipes and seal the annular space. Through its design structure, it can firmly hang the casing pipes to ensure their stability and safety in the wellbore.
[0003] Considering that traditional equipment is of an integrated design, since many small components are added inside the traditional equipment during design, the processing difficulty is relatively high, which will make the processing accuracy finer and result in an increase in production costs. Summary of the Invention
[0004] The purpose of the utility model is to provide a new type of multifunctional combined integrated slip hanger to solve the problems raised in the above background technique.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a new type of multifunctional combined integrated slip hanger, including a housing. A connecting ring is fixedly connected to the inner wall of the housing, and there are four groups of connecting rings. A slip body is arranged on the inner wall of the housing. Adjusting holes are opened on the inner wall of the housing, and there are multiple groups of adjusting holes; a full-thread adjusting screw is threadedly connected to the inner wall of each group of adjusting holes; a rectangular sealing ring is rotatably connected to the outer wall of each full-thread adjusting screw near the top. The bottom of the full-thread adjusting screw abuts against the top of the slip body; the top of the rectangular sealing ring is fixedly connected to a pressing plate; the outer wall of the slip body abuts against the inner wall of the housing. A connecting groove is opened on one side of the slip body; the outer wall of the connecting ring is clamped with the inner wall of the connecting groove.
[0007] By adopting the above technical solution, by rotating the pressing screw to push the pressing plate and making the rectangular sealing ring contact and be compressed by the housing, at this time, the distance between the rectangular sealing ring and the housing is shortened, and at the same time, the full-thread adjusting screw will move downward. When the full-thread adjusting screw moves downward, it will push the slip body to perform clamping. At this time, the clamping effect can be achieved. Through the split design, the processing difficulty can be reduced, and it is also convenient to replace the components inside the equipment when they are damaged.
[0008] Further, multiple pressing holes are opened on the top of the pressing plate, and there are multiple groups of pressing holes; each group of pressing holes extends from the top of the pressing plate to the inside of the housing. A pressing screw is threadedly connected to the inner wall of the pressing hole, and the pressing hole is threadedly connected to the pressing plate; the inner wall of the pressing plate is threadedly connected to the outer wall of the pressing screw.
[0009] With the above technical solution, the housing and the pressing plate are fixed by installing the pressing screw in the pressing hole. There is a redundant space inside the pressing hole. When it is necessary to clamp a thinner object, the pressing screw can be further tightened, and at the same time, the rectangular sealing ring will be compressed to achieve the effect.
[0010] Further, a handle hole is provided on the inner wall of the housing near the bottom, and a handle body is rotatably connected to the inner wall of the handle hole; one end of the handle body close to the chuck body is threadedly connected to the inner wall of the chuck body.
[0011] With the above technical solution, the angle of the chuck body can be manually adjusted through the setting of the handle body, so as to achieve a better clamping effect. At the same time, since it is manually adjusted for clamping, the torque of the person cannot damage the drill string when the chuck body is clamped with the drill string.
[0012] Further, mounting holes are provided on the inner wall of the housing, and there are two groups of mounting holes. Fixing screws are threadedly connected to the inner walls of the mounting holes.
[0013] With the above technical solution, the housing can be installed on other equipment through the setting of the fixing screws, and the installation is also made simple by using the fixing screws for installation.
[0014] Further, a lifting rope is clamped on the top of the housing, and there are two groups of lifting ropes.
[0015] With the above technical solution, the setting of the lifting rope can make the transfer work more convenient, and it can be directly removed when not needed.
[0016] Further, the housing and the pressing plate are of a split type, and the housing and the pressing plate are fixed by pressing screws to achieve integration.
[0017] With the above technical solution, the split design can reduce the processing difficulty, and it is also convenient to replace the components inside the equipment when they are damaged.
[0018] The utility model has the following beneficial effects:
[0019] 1. By rotating the pressing screw, it pushes the pressing plate and makes the rectangular sealing ring contact and be compressed by the housing. At this time, the distance between the rectangular sealing ring and the housing is shortened, and at the same time, the all-thread adjusting screw will move downward. When the all-thread adjusting screw moves downward, it will push the chuck body to perform clamping. At this time, the clamping effect can be achieved. The split design can reduce the processing difficulty, and it is also convenient to replace the components inside the equipment when they are damaged.
[0020] 2. When encountering a situation where the drill string needs to be even thinner, it will be impossible to proceed. At the same time, fixing only with bolts will result in a relatively low clamping accuracy. If it is not fully clamped during clamping, loosening may occur, but if it is clamped too tightly, the drill string may be damaged. By setting the handle body, the angle of the slip body can be manually adjusted, thus achieving a better clamping effect. At the same time, because it is manually adjusted for clamping, when the slip body is clamped with the drill string, the torque of the person cannot damage the drill string.
[0021] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
[0022] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for describing the embodiments will be briefly introduced below.
[0023] Figure 1 It is a schematic diagram of the overall structure.
[0024] In the drawings, the list of components represented by each reference numeral is as follows:
[0025] In the figure: 1, housing; 2, handle body; 3, fixing screw; 4, connecting ring; 5, slip body; 6, rectangular sealing ring; 7, pressing plate; 8, pressing screw; 9, lifting rope; 10, full-thread adjusting screw. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.
[0027] Please refer to Figure 1 As shown, the present utility model is a new type of multi-functional combined integrated slip hanger, including a housing 1. The inner wall of the housing 1 is fixedly connected with a connecting ring 4, and there are four groups of connecting rings 4. The inner wall of the housing 1 is provided with a slip body 5. The inner wall of the housing 1 is provided with adjusting holes, and there are multiple groups of adjusting holes; the inner wall of each group of adjusting holes is threadedly connected with a full-thread adjusting screw 10; the outer wall of each group of full-thread adjusting screws 10 near the top is rotatably connected with a rectangular sealing ring 6. The bottom of the full-thread adjusting screw 10 abuts against the top of the slip body 5; the top of the rectangular sealing ring 6 is fixedly connected with a pressing plate 7; the outer wall of the slip body 5 abuts against the inner wall of the housing 1. A connecting groove is opened on one side of the slip body 5; the inner wall of the connecting groove is clamped with the outer wall of the connecting ring 4.
[0028] In this embodiment, considering that traditional devices are integrally designed and usually use bolts to directly push and clamp the slips during use. Since many small components are added inside the traditional devices during design, although better clamping and other advantages can be obtained through the small components, the processing difficulty is relatively high during processing, and the processing accuracy becomes finer, resulting in an increase in production costs.
[0029] The housing 1 and the pressure plate 7 are fixed by the compression screw 8. At the same time, the compression screw 8 is rotated to push the pressure plate 7, so that the rectangular sealing ring 6 contacts the housing 1 and is compressed. At this time, the distance between the rectangular sealing ring 6 and the housing 1 is shortened, and at the same time, the all-thread adjusting screw 10 moves downward. When the all-thread adjusting screw 10 moves downward, it will push the slip body 5 to perform clamping. At this time, the clamping effect can be achieved. Through the split design, the processing difficulty can be reduced, and it is also convenient to replace the components inside the device when they are damaged.
[0030] Specifically, the top of the pressure plate 7 is provided with compression holes, and there are multiple groups of compression holes; each group of compression holes extends from the top of the pressure plate 7 to the inside of the housing 1. The inner wall of the compression hole is threadedly connected with the compression screw 8, and the compression hole is threadedly connected with the pressure plate 7; the inner wall of the pressure plate 7 is threadedly connected with the outer wall of the compression screw 8.
[0031] In this embodiment, the housing 1 and the pressure plate 7 are fixed by installing the compression screw 8 in the compression hole. There is a redundant space inside the compression hole. When it is necessary to clamp a finer object, the compression screw 8 can be further tightened, and at the same time, the rectangular sealing ring 6 will be compressed to achieve the effect.
[0032] Specifically, a handle hole is provided on the inner wall of the housing 1 near the bottom, and a handle body 2 is rotatably connected to the inner wall of the handle hole; one end of the handle body 2 close to the slip body 5 is threadedly connected to the inner wall of the slip body 5.
[0033] In this embodiment, in the prior art, bolts are directly used for the clamping operation, and when it comes to the situation where the drill string is finer, it will not be possible to perform the operation. At the same time, only using bolts for the fixing operation will result in a lower clamping accuracy. If the clamping is not complete during clamping, it may cause loosening, but if the clamping is too tight, it may cause damage to the drill string.
[0034] Through the setting of the handle body 2, the angle of the slip body 5 can be manually adjusted, so as to achieve a better clamping effect. At the same time, since it is a manual adjustment of the clamping, the torque of the person cannot damage the drill string when the slip body 5 is clamped with the drill string.
[0035] Specifically, two installation holes are provided on the inner wall of the housing 1, and fixing screws 3 are threadedly connected to the inner walls of the installation holes.
[0036] In this embodiment, the housing 1 can be mounted on other devices by means of the fixing screws 3, and the installation by the fixing screws 3 also achieves the simplicity of installation.
[0037] Specifically, two sets of lifting ropes 9 are snap-connected to the top of the housing 1.
[0038] In this embodiment, the setting of the lifting ropes 9 can make the transfer work more convenient, and they can be directly removed when not needed.
[0039] Specifically, the housing 1 and the pressing plate 7 are of a split type, and the housing 1 and the pressing plate 7 are fixed by the pressing screws 8 to achieve integration.
[0040] In this embodiment, the split design can reduce the processing difficulty, and it is also convenient to replace the components inside the device when they are damaged.
[0041] During use,
[0042] First, the housing 1 and the pressing plate 7 are fixed by installing the pressing screws 8 in the pressing holes. There is redundant space inside the pressing holes. When it is necessary to snap-connect thinner objects, the pressing screws 8 can be further tightened. When the pressing screws 8 rotate, they will push the pressing plate 7, and the rectangular sealing ring 6 will contact and be compressed by the housing 1. At this time, the distance between the rectangular sealing ring 6 and the housing 1 is shortened, and at the same time, the all-thread adjusting screw 10 will move downward. When the all-thread adjusting screw 10 moves downward, it will push the chuck body 5 to perform snap connection. At this time, the snap connection effect can be achieved. The split design can reduce the processing difficulty, and it is also convenient to replace the components inside the device when they are damaged.
[0043] Finally, the angle of the chuck body 5 can be manually adjusted through the setting of the handle body 2, so as to achieve a better snap connection effect. At the same time, because it is a manual snap connection, the torque of the person cannot damage the drill string when the chuck body 5 is snap-connected to the drill string.
[0044] The above-disclosed preferred embodiments of the present invention are only used to help illustrate the present invention. The present specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the relevant technical fields can well understand and utilize the present invention.
