Abstract
The utility model discloses a kind of oil pipe inside weld removal device, comprise the supporting positive cover of fixing oil pipe, described supporting positive cover is disc-shaped structure, and its left end inner stopper end face contacts fixing with oil pipe outer peripheral face; The right side of described supporting positive cover is connected with the contiguous block of integral structure, and this contiguous block is provided with upper and lower two inner sleeves, in the cannelure be along the circumferential direction provided with being fitted into supporting positive cover respectively and in the centre bore of supporting positive cover; The upper inner sleeve of described contiguous block is connected with cutter shaft by screw thread, and cutter shaft front end is fixed with cutter, and lower inner sleeve is equipped with power transmission shaft, and this power transmission shaft is connected by belt wheel with rotary electric machine power shaft.The utility model, by adopting the rotary feed mode of driven by motor, increases oil pipe inside weld excision extension, for the oil pipe of different size diameter, particularly large diameter oil tube, not only weld seam excision is effective, and can greatly increase work efficiency, time saving and energy saving material saving.
Description
Technical field
The utility model relates to the auxiliary process facility of Oil/gas Well coiled tubing processing, is specifically related to a kind of oil pipe inside weld removal device.
Background technology
At China's oilfield, the coiled tubing as speed tubing string is provided with in Oil/gas Well, this kind of coiled tubing is in pressure construction operation process, need be clean by the weld seam complete resection in pipe, then with torsion-resistant ring pressure connector, above-mentioned coiled tubing could be connected with the coiled tubing published in instalments on cylinder.China's notification number is that the utility model patent of 202963651 U discloses a kind of instrument being applied to weldering grain husk excision in coiled tubing, solves by manually coming manually to excise brought inefficiency to coiled tubing inwall weld seam and weld seam excises not totally, thoroughly do not affect the problem of serviceability.But this technical scheme, because its cutter is arranged between two parties, position is fixed, and is only suitable for the oil pipe inside weld excision of external diameter of the same race, and its orthoscopic feed mode, for the excision of the weld seam on large diameter oil tube internal perisporium, effect is not then clearly, and as thought complete resection, the appearance and size of instrument will strengthen, consumptive material is many, causes waste.
Summary of the invention
For above-mentioned defect, the utility model improves existing oil pipe inside weld removal tool, provide a kind of applicable different size particularly major diameter inside weld remove, adopt rotary feed, effective, efficiency is high, the oil pipe inside weld removal device of handled easily.
The utility model is achieved through the following technical solutions: a kind of oil pipe inside weld removal device, comprises the supporting positive cover of fixing oil pipe, and described supporting positive cover is disc-shaped structure, and its left end inner stopper end face contacts fixing with oil pipe outer peripheral face; The right side of described supporting positive cover is connected with the contiguous block of integral structure, and this contiguous block is provided with upper and lower two inner sleeves, in the cannelure be along the circumferential direction provided with being fitted into supporting positive cover respectively and in the centre bore of supporting positive cover; The upper inner sleeve of described contiguous block is connected with cutter shaft by screw thread, and cutter shaft front end is fixed with cutter, and lower inner sleeve is equipped with power transmission shaft, and this power transmission shaft is connected by belt wheel with rotary electric machine power shaft.
The technical scheme that the utility model improves further is: described cutter shaft is connected with feed motor by the handle of its rear end, rotates and realize forward/back blade under the manipulation of motor.
The technical scheme that the utility model further improves is: described feed motor and rotary electric machine turn and can synchronously realize rotating.
The utility model, by adopting the rotary feed mode of driven by motor, increases oil pipe inside weld excision extension, for the oil pipe of different size diameter, particularly large diameter oil tube, not only weld seam excision is effective, and can greatly increase work efficiency, time saving and energy saving material saving.Meanwhile, feed motor and rotary electric machine turn synchronous axial system, make the rotation limit feeding of cutter limit, and revolution and rotation are synchronously carried out, and the different cut surfaces making full use of cutter cut, and successful and cutter can not local lesions, are conducive to the maintenance of cutter.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, a kind of oil pipe inside weld removal device, comprises supporting positive cover 1, is disc-shaped structure, and its left end inner stopper end face contacts fixing with oil pipe outer peripheral face.Supporting positive cover 1 is provided with the cannelure 11 and centre bore 12 that along the circumferential direction arrange.
As shown in Figure 1, 2, the right side of described supporting positive cover 1 is provided with the contiguous block 2 of integral structure, and this contiguous block 2 is provided with upper and lower two inner sleeves 21 and 22, corresponding respectively with the position of the cannelure 11 of supporting positive cover, centre bore 12, size, assembly connection.Upper inner sleeve 21 is also provided with the internal thread corresponding with cutter shaft 3.
As shown in Figure 1, cutter shaft 3 is screw-rod structure, and screw in from the upper inner sleeve 21 of contiguous block 2, its front end is fixed with cutter 4, and rear end is connected with handle 5, and this handle 5 is connected with feed motor, rotates and realize forward/back blade under the manipulation of motor.
Be equipped with power transmission shaft 6 in the lower inner sleeve 22 of described contiguous block 2, this power transmission shaft 6 is connected by belt wheel 7 with the power shaft of rotary electric machine 8.
Described rotary electric machine 8 and control the feed motor that cutter shaft rotates and can synchronously arrange, synchronous axial system, realizes limit rotation limit feed, utilizes the different cut surfaces of cutter to cut, make cutter can not concentrated wear serious, be conducive to the maintenance of cutter.
