Background Art

[0002] At present, the application of coiled tubing is becoming more and more extensive. Especially for the multi - channel multi - functional coiled tubing containing optical fiber cables, it plays a key role in many fields such as drilling, well - drilling engineering, road and bridge, ocean, aerospace, polar region, urban underground construction and rescue. Currently, the mature coiled tubing storage and release equipment is mainly winches or hoists. For the load - bearing continuous steel - rope type winch, it is convenient and fast to use. However, for the winch of the multi - channel multi - functional coiled tubing with electric cables, there are many problems in use and it cannot well meet the requirements. Therefore, a coiled tubing large - capacity storage and transportation device has been invented. However, when the coiled tubing is full in the first storage cylinder of the pipe - storage mechanism and needs to enter the second storage cylinder through the transition storage cylinder, an automatic alignment mechanism is required to complete this process. This automatic alignment mechanism for the pipe - storage sleeve is an essential component of the coiled tubing large - capacity storage and transportation device. Therefore, it is very necessary to invent an automatic alignment mechanism for the pipe - storage sleeve of the coiled tubing large - capacity storage and transportation device. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic alignment mechanism for a pipe - storage sleeve for a coiled tubing large - capacity storage and transportation device, to achieve dynamic alignment between the storage and release guiding mechanism and the position where the coiled tubing enters or exits the cylinder, prevent the coiled tubing from being damaged due to abnormal buckling deformation, and provide guarantee for the smooth operation of the coiled tubing large - capacity storage and transportation device.

[0005] The alignment power motor is fixedly connected to the alignment power motor bracket, and the alignment power motor bracket is fixedly connected to the alignment beam. The alignment synchronous transmission mechanism is arranged on the alignment power motor bracket and meshes with the alignment power motor. The alignment beam support is in sliding fit with the alignment beam. Along the direction of the alignment beam, 2N (N≥2) alignment bracket pressure sliding bearings and 2N (N≥2) alignment bracket limit sliding bearings are respectively arranged on the bottom beam of the alignment bracket. The alignment proximity sensors are fixedly connected to both sides of the alignment bracket. There are 4 alignment proximity limit mechanisms, which are respectively fixed at the set positions on the upper surface of the alignment beam. When the alignment proximity sensors fixed on the alignment bracket move to the alignment proximity limit mechanisms, the alignment proximity sensors are touched or infrared-sensed through the mechanisms and generate signals, which are transmitted to the control system, thereby preventing the storage and guiding mechanism from exceeding its set movement range. There are two alignment traveling lead screws. The head and tail ends of the alignment traveling lead screws are respectively connected to the alignment synchronous transmission mechanism and the alignment traveling lead screw reinforcement seat, and are in screw fit with the alignment bracket.

The function of the present invention is to dynamically align the storage and placement guiding mechanism 5 with the position where the coiled tubing 9 is entering or exiting the cylinder, preventing the coiled tubing 9 from being damaged due to abnormal buckling deformation;

[0013] The alignment power motor 603 is fixedly connected to the alignment power motor bracket 601, and the alignment power motor bracket 601 is fixedly connected to the alignment beam 6012. The alignment synchronous transmission mechanism 602 is arranged on the alignment power motor bracket 601 and meshes with the alignment power motor 603. The alignment beam support 604 is in sliding fit with the alignment beam 6012 and can move relative to the alignment beam 6012, and is used for fine-tuning the position when the automatic alignment mechanism 6 of the pipe storage sleeve is fixed to the traction electric control trolley 7. The storage and placement guiding mechanism interface 605 is fixedly connected to the guiding mechanism fixing seat 501, fixing the storage and placement guiding mechanism 5 and the alignment bracket 606 together. On the bottom beam of the alignment bracket 606, 2N (N≥2) alignment bracket pressure-bearing sliding bearings 6014 and 2N (N≥2) alignment bracket limit sliding bearings 6015 are arranged along the direction of the alignment beam 6012. The alignment proximity sensors 607 are fixedly connected to both sides of the alignment bracket 606. There are 4 alignment proximity limit mechanisms 608, which are respectively fixed at the set positions on the alignment beam 6012. When the alignment proximity sensors 607 fixed on the alignment bracket 606 move to the alignment proximity limit mechanisms 608, the alignment proximity sensors 607 are touched or infrared-sensed through the mechanism and generate signals, which are transmitted to the control system, thereby preventing the storage and placement guiding mechanism 5 from exceeding its set movement range. Two alignment traveling screws 609 are provided. The head and tail ends of the alignment traveling screws 609 are respectively connected to the alignment synchronous transmission mechanism 602 and the alignment traveling screw reinforcement seat 6010, and are in screw fit with the alignment bracket 606. The alignment synchronous transmission mechanism 602 synchronously transmits the rotational torque of the alignment power motor 603 to the alignment traveling screws 609. The alignment traveling screw reinforcement seat 6010 is fixed on the cross beam between the alignment beams 6012;

[0014] The interface 6011 of the slewing support mechanism provided on the alignment beam 6012 is connected to the interface of the pipe storage sleeve automatic alignment mechanism 3.

[0015] The working principle and usage process of the present invention:

[0016] Driven by the alignment power motor 603 of the present invention, the alignment synchronous transmission mechanism 602 drives the alignment walking lead screw 609 to rotate. Then, the alignment support 606 moves back and forth along the axial direction of the alignment walking lead screw 609. When the alignment support 606 moves away from the interface 6011 of the slewing support mechanism and reaches the position where the alignment proximity sensor 607 contacts or senses the alignment proximity limit mechanism 608, it stops, indicating that the distal extreme position has been reached. When the alignment support 606 moves close to the interface 6011 of the slewing support mechanism and reaches the position where the alignment proximity sensor 607 contacts or senses the alignment proximity limit mechanism 608, it stops, indicating that the proximal extreme position has been reached.
