DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 As shown, a deep well coiled tubing lowering device comprises a reel 1, baffles 2 are fixedly installed at the edges of both sides of the reel 1, docking ports 4 are opened at both ends of the reel 1, a connector 3 is provided on the reel 1, a driving mechanism 5 is connected to the connector 3, and a shift mechanism 6 comprises an input shaft 601 movably installed in a device housing 504, one end of the connector 3 is fixed on the reel 1, and the other end of the connector 3 is fixed on the output shaft 501. The torque of the output shaft 501 can be increased by the coordinated use of the driving mechanism 5 and the shift mechanism 6, so that the reel 1 can reel in heavier coiled tubing, and the rotation speed of the output shaft 501 can be increased according to the situation, so that the released coiled tubing can be quickly reeled in when it is short.

[0020] like Figure 2 As shown, the driving mechanism 5 includes an equipment housing 504 arranged on one side of the winding wheel 1, a mounting groove 505 is opened on the equipment housing 504, a bearing 506 is arranged in the mounting groove 505, an output shaft 501 is movably installed in the equipment housing 504, an output pinion 502 and an output gear 503 are fixedly installed on the output shaft 501, the output pinion 502 and the output gear 503 are both movably installed in the equipment housing 504 through the output shaft 501, the output shaft 501 and the input shaft 601 are both movably installed in the equipment housing 504 through the bearing 506, a sliding groove is opened on the input shaft 601, and an equipment limit clamp 606 is slidably installed on the input shaft 601 through the sliding groove.

[0021] Specifically, the output pinion 502 and the output gear 503 can both drive the output shaft 501 to rotate. After the output shaft 501 rotates, it will drive the winding wheel 1 to rotate, thereby controlling the winding or release of the coiled tubing.

[0022] like Figure 3As shown, the shift mechanism 6 includes an input shaft 601 movably mounted in the device housing 504, an input pinion 602 and an input gear 603 are movably mounted on the input shaft 601, a limit block 604 is fixedly mounted on the input pinion 602 and the input gear 603, a limit holder 606 is slidably mounted on the input shaft 601 between the input pinion 602 and the input gear 603, a shift paddle 605 is movably mounted on the limit holder 606, a sliding groove is provided on the input shaft 601, the device limit holder 606 is slidably mounted on the input shaft 601 through the sliding groove, the input pinion 602 and the input gear 603 are both movably mounted in the device housing 504 through the input shaft 601, and the input pinion 602 is meshed with the output gear 503, and the input gear 603 is meshed with the output pinion 502.

[0023] Specifically, the shift paddle 605 can drive the limit card seat 606 to move left and right, so that it can be stuck on the limit card block 604 on the input small gear 602 or the input large gear 603. The limit card seat 606 will drive the group of gears whose limit card block 604 is stuck to rotate.

[0024] It should be noted that the utility model is a deep well coiled tubing running equipment. When in actual use, the position of the shift paddle 605 is first adjusted according to the situation. When retracting a heavier coiled tubing, the shift paddle 605 can be used to shift the limit clamp 606 to contact the input pinion 602. After the limit clamp 606 contacts the input pinion 602, the input pinion 602 will drive the output gear 503 to rotate, thereby increasing the torque of the output shaft 501, which is convenient for the winding wheel 1 to retract the heavier coiled tubing. When retracting a lighter coiled tubing, the shift paddle 605 can be used to shift the limit clamp 606 to contact the input gear 603. After the limit clamp 606 contacts the input gear 603, the input gear 603 will drive the output pinion 502 to rotate, thereby increasing the rotation speed of the output shaft 501, and quickly retracting the released coiled tubing when it is short.
