Technical Field

[0001] The utility model relates to the field of petroleum engineering, and particularly relates to a pipe fitting tooling. Background Art

[0002] When installing a large-size regulating valve on a pipeline, generally, the regulating valve is first installed on the pipeline by welding to meet the construction requirements of stress-free pipe fitting. In addition, before the start of pipeline testing work, it is necessary to remove the regulating valve and replace it with a short section for pressure testing and purging work. After the testing work is completed, the regulating valve is installed on the pipeline again.

[0003] Since the size of the regulating valve installed on the pipeline is generally large, during the disassembly and installation process, a huge workload will be generated, and the procedures and costs involved in the disassembly and installation of the regulating valve are also relatively complex and demanding. In addition, if the regulating valve is frequently disassembled and installed, it is very easy to cause irreparable damage to the valve body itself and the pipeline, thus seriously affecting the construction efficiency.

[0004] However, there is still no device in the prior art that can solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pipe fitting tooling, which can effectively replace a large-size regulating valve to meet the various construction requirements of pipe fitting work.

[0021] In the drawings, the same components are denoted by the same reference numerals. The drawings are not drawn to actual scale. Detailed implementation manners

[0022] The present utility model will be further described below in conjunction with the drawings.

[0023] Figure 1 Schematically shows the structure of the pipe fitting tooling 100 according to the present utility model. As Figure 1 shown, the pipe fitting tooling 100 according to the present utility model mainly includes a screw rod 10, a matching mechanism 20, a supporting mechanism 30, and an adjusting mechanism 40. Among them, the screw rod 10 is arranged to extend longitudinally. The matching mechanism 20 is sleeved outside the screw rod 10 and is partially engaged with the screw rod 10. The supporting mechanism 30 is arranged outside the matching mechanism 20, and the adjusting mechanism 40 can partially pass through the supporting mechanism 30 to form an engagement with the matching mechanism 20, so as to urge the screw rod 10 to move axially. The content is introduced below.

[0024] According to the present utility model, as Figure 1 shown, the matching mechanism 20 includes a bevel gear 21. The bevel gear 21 includes a second bevel gear unit 211 and a third bevel gear unit (not shown) fixedly connected to the second bevel gear unit 211. The second bevel gear unit 211 is configured in the form of a frustum of a cone and can form a tight meshing relationship with the first bevel gear unit 51 (introduced below); the third bevel gear unit is configured in the form of a sleeve and is arranged inside the first matching part 221 (introduced below). In addition, the inner surface of the third bevel gear unit forms a tight meshing relationship with the screw rod 10. In this way, it is easier to make the screw rod 10 move axially in subsequent work, so as to meet the construction requirements of pipe fitting.

[0025] According to the present utility model, as Figure 1As shown, the mating mechanism 20 further includes a mating part 22. The mating part 22 is configured in the form of a stepped sleeve and includes a first mating portion 221 and a second mating portion 222. Among them, the diameter of the first mating portion 221 is larger than that of the second mating portion 222. The inside of the first mating portion 221 can accommodate the third bevel gear unit, and the first mating portion 221 is in sliding connection with the third bevel gear unit. In this way, the third bevel gear unit can more easily urge the screw 10 to move axially, thus meeting the requirements of precise pipe laying. The second mating portion 222 can extend into the bottom plate 313 (introduced below) to form a fixed connection. In this way, the screw 10 can be prevented from contacting the bottom plate 313, thereby effectively protecting the screw 10. It is easy to understand that the mating relationship between the bevel gear 21 and the mating part 22 is well known to those skilled in the art, so it will not be elaborated here.

[0026] According to the present invention, as Figure 1 shown, the support mechanism 30 includes a support frame 31 and a sleeve 32 arranged on the support frame 31. Among them, the support frame 31 is configured in a U-shaped structure and includes a first side plate 311, a second side plate 312 and a bottom plate 313. Among them, both the first side plate 311 and the second side plate 312 are arranged along the longitudinal direction, and the bottom plate 313 is arranged along the transverse direction. Preferably, the sleeve 32 is arranged horizontally on the first side plate 311. In this way, the adjustment mechanism 40 can perform the pipe laying work more stably under the support of the sleeve 32. However, according to the actual construction requirements, the sleeve 32 can also be arranged on the second side plate 312.

[0027] According to the present invention, as Figure 1 shown, the adjustment mechanism 40 includes an adjustment assembly 50 that can partially pass through the sleeve 32 and engage with the bevel gear 21. The adjustment assembly 50 includes a first bevel gear unit 51 and a connecting rod (not shown). That is to say, the connecting rod is arranged inside the sleeve 32, and the first end of the connecting rod is fixedly connected to the first bevel gear unit 51 arranged outside the sleeve 32. The first bevel gear unit 51 is configured in the form of a frustum of a cone. In this way, the first bevel gear unit 51 and the second bevel gear unit 211 can have a larger meshing area, so as to ensure that they can form a tight meshing relationship, and further enable the pipe laying tooling 100 to always be in a stable working state. It is easy to understand that the mating relationship between the adjustment assembly 50 and the sleeve 32 is well known to those skilled in the art, so it will not be elaborated here.

[0028] According to an embodiment of the present utility model, the volume of the first bevel gear unit 51 is smaller than that of the second bevel gear unit 211. In this way, when the first bevel gear unit 51 and the second bevel gear unit 211 have the same movement path, the first bevel gear unit 51 rotates more turns. Thus, the position of the screw rod 10 in the axial direction can be adjusted more accurately, so as to meet the construction requirements of the pipe installation.

[0029] According to the present utility model, as Figure 1 shown, the adjusting mechanism 40 further includes an adjusting handwheel 41 disposed outside the support frame 31. The adjusting handwheel 41 includes a gripping portion configured as an annular structure and a connecting portion fixedly connected to the second end of the above-mentioned connecting rod. In this way, by rotating the adjusting handwheel 41, the first bevel gear unit 51 and the bevel gear 21 can be driven to rotate, so that the screw rod 10 moves in the axial direction through the third bevel gear unit, and further the pipe installation tooling 100 can more easily meet the requirements for pipe installation.

[0030] According to an embodiment of the present utility model, the present utility model mainly adjusts the position of the screw rod 10 in the axial direction by rotating the adjusting handwheel 41. Specifically, it is to convert the linear rotation distance of the adjusting handwheel 41 into the movement distance of the screw rod 10 in the axial direction. Therefore, the present utility model can also replace the adjusting handwheel 41 with different sizes according to actual construction requirements. Thus, the position of the screw rod 10 in the axial direction can be adjusted more precisely through the adjusting handwheel 41. In addition, compared with the regulating valve in the prior art, the dimensional deviation of the pipe installation tooling 100 can be controlled within 2 mm.

[0031] According to an embodiment of the present utility model, as Figure 1 shown, the pipe installation tooling 100 further includes a first flange 1. The screw rod 10 can extend into the first flange 1 to form a fixed connection. In addition, a plurality of through holes are provided on the first flange 1, so as to be effectively connected with external tools, and further provide a stable working environment for the pipe installation tooling 100.

[0032] Figure 2 It is a partial structural schematic diagram of the pipe installation tooling 100 according to the present utility model. According to the present utility model, as Figure 1 and 2 shown, the pipe installation tooling 100 further includes a pair of first limiting plates 60. The two limiting plates 60 are both arranged longitudinally on the first flange 1. According to an embodiment of the present utility model, the first limiting plate 60 can be connected to the support frame 31 to form a box structure. In this way, the bevel gear 21 and the first bevel gear unit 51 can be effectively protected, so as to extend the service life of the pipe installation tooling 100.

[0033] Figure 3Schematic diagram of the first limiting plate 60 in the pipe fitting tooling 100 according to the present utility model. According to an embodiment of the present utility model, as Figure 3 shown, a sliding groove 61 is further provided on the first limiting plate 60. The sliding groove 61 is configured as a through groove extending longitudinally, thereby providing a fixed environment for the subsequent limitation of the support frame 31.

[0034] According to an embodiment of the present utility model, as Figure 2 and 3 shown, second limiting plates 314 are provided at both ends of the bottom plate 313. The second limiting plates 314 are arranged to extend longitudinally and are in contact with the first limiting plate 60. In this way, when the axial position of the screw 10 is adjusted, the first limiting plate 60 fixes the second limiting plate 314 on the sliding groove 61 through screws, thereby realizing the limitation of the axial position of the screw 10. In this way, it can be ensured that the screw 10 can have a stable working state during the subsequent working process.

[0035] According to an embodiment of the present utility model, the pipe fitting tooling 100 further includes a second flange 2. The second flange 2 is sleeved outside the screw 10, and the second flange 2 forms a fixed connection with the top of the support frame 31. Thus, the first limiting plate 60, the support frame 31 and the second flange 2 constitute a closed space, thereby effectively protecting the bevel gear 21 and the first bevel gear unit 51, and thus prolonging the service life of the pipe fitting tooling 100.

[0036] The present utility model can effectively replace large-size regulating valves, thereby meeting the various construction requirements of pipe fitting work. Compared with large-size regulating valves, on the one hand, the present utility model can avoid the problem of frequent disassembly and assembly, thereby effectively reducing the workload and improving the work efficiency. On the other hand, by replacing the adjusting handwheels 41 of different sizes, the axial position of the screw 10 can be adjusted more precisely. In addition, the present utility model is convenient and fast to install and can effectively reduce costs.

[0037] The above is only the preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art can easily make changes or variations within the public scope of the present utility model, and such changes or variations should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
