Description

Technical Field

[0001] The present invention relates to fields such as drilling, well drilling engineering, road and bridge, ocean, aerospace, polar region, urban underground construction and rescue, and particularly relates to a storage and placement guiding mechanism for a coiled tubing large-capacity storage and transportation device. Background Art

[0002] At present, coiled tubing is increasingly widely used. Especially the multi-channel multi-functional coiled tubing containing optical fiber cables 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 placement equipment is mainly a winch or a hoist. For the load-bearing continuous steel rope type hoist, it is convenient and fast to use. 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 its requirements. For this reason, a coiled tubing large-capacity storage and transportation device has been invented. However, due to the large elasticity of the coiled tubing, a downward external force is required to cause elastic deformation of the coiled tubing to smoothly enter the pipe storage mechanism, and vice versa. Such a storage and placement guiding mechanism is an essential component of the coiled tubing large-capacity storage and transportation device. Therefore, it is very necessary to invent a storage and placement guiding mechanism for the coiled tubing large-capacity storage and transportation device. Summary of the Invention

[0003] The purpose of the present invention is to provide a storage and placement guiding mechanism for a coiled tubing large-capacity storage and transportation device, solve the problem that the coiled tubing cannot enter or exit the pipe storage mechanism, and provide guarantee for the smooth operation of the coiled tubing large-capacity storage and transportation device.

[0004] The storage and placement guiding mechanism of the coiled tubing large-capacity storage and transportation device includes a first storage and placement guiding mechanism assembly, a second storage and placement guiding mechanism assembly, a guiding mechanism fixing seat, a guiding mechanism support and a guiding power motor. The upper end of the guiding mechanism fixing seat is fixedly connected to the guiding mechanism support. The first storage and placement guiding mechanism assembly and the second storage and placement guiding mechanism assembly are symmetrically arranged inside the guiding mechanism support. The guiding power motor is arranged on the guiding mechanism support and the rotor of the guiding power motor is fixedly connected to the driving shaft of the first storage and placement guiding mechanism assembly;

[0005] The first storage and placement guiding mechanism assembly includes a meshing gear, a guiding semi-open chain type clamping block group, a guiding clamping support, a guiding chain tensioning mechanism, a guiding semi-open chain type clamping block slideway guiding driving sprocket, a guiding driven sprocket and a guiding chain tensioning bolt;

[0006] The two ends of the driving shaft are rotatably connected to the guiding mechanism support, and a meshing gear and a guiding driving sprocket are fixedly connected to the driving shaft;

[0007] The two ends of the driven shaft are respectively rotationally connected to the guide chain tensioning mechanism. A guide driven sprocket is fixedly connected to the driven shaft. The guide semi-open chain type clamping block group meshes outside the guide driving sprocket and the guide driven sprocket. The guide chain tensioning mechanism is in sliding and limiting cooperation with the guide mechanism bracket. The guide chain tensioning bolt is in threaded cooperation with the guide mechanism bracket and abuts against the guide chain tensioning mechanism. A guide semi-open chain type clamping block slideway is slidably connected to the inner side of the guide semi-open chain type clamping block group, and the fixed surface of the guide semi-open chain type clamping block slideway is fixedly connected to the guide clamping support.

[0008] The number of the clamping force adjusting screws is 2N (N≥1). The clamping force adjusting screws pass through the guide clamping support of the first storage and guiding mechanism assembly and are in threaded connection with the guide clamping support of the second storage and guiding mechanism assembly.

[0009] The beneficial effects of the present invention:

[0010] 1. By rotating the guide chain tensioning bolt, the distance between the guide driving sprocket and the guide driven sprocket in the same group is adjusted, thereby adjusting the tension degree of the guide semi-open chain type clamping block group.

[0011] 2. The clamping force adjusting screw is used to adjust the distance between the guide clamping support of the first storage and guiding mechanism assembly and the guide clamping support of the second storage and guiding mechanism assembly, and further adjust the distance between two opposite guide semi-open chain type clamping block slideways; thereby adjusting the friction force between the guide semi-open chain type clamping block group and the coiled tubing.

[0012] 3. Through the clamping and transportation of the coiled tubing by the first storage and guiding mechanism assembly and the second storage and guiding mechanism assembly, it is easier for the coiled tubing to enter and exit the storage tube and the transition tube.

[0016] Referring to the attached drawings, the storage and guiding mechanism of the coiled tubing large-capacity storage and transportation device includes a first storage and guiding mechanism assembly, a second storage and guiding mechanism assembly, a guiding mechanism fixing seat 501, a guiding mechanism support 502, and a guiding power motor 508. The upper end of the guiding mechanism fixing seat 501 is fixedly connected to the guiding mechanism support 502. The first storage and guiding mechanism assembly and the second storage and guiding mechanism assembly are symmetrically arranged inside the guiding mechanism support 502. The guiding power motor 508 is arranged on the guiding mechanism support 502, and the rotor of the guiding power motor 508 is fixedly connected to the driving shaft of the first storage and guiding mechanism assembly. The function of the storage and guiding mechanism 5 is to overcome the bending stress of the coiled tubing through sufficient friction, and it can not only inject the coiled tubing into the sleeve-type large-capacity storage tube mechanism 8, but also accurately take out the coiled tubing from the sleeve-type large-capacity storage tube mechanism 8 and transport it to the working area through the gooseneck reversing mechanism 1 and the storage and injection mechanism 2. The function of the guiding mechanism support 502 is to provide support and force transmission for the meshing gear 503, the guiding semi-open chain-type clamping block group 504, the clamping force adjusting screw 505, the guiding clamping support 506, the guiding chain tensioning mechanism 507, the guiding power motor 508, the guiding semi-open chain-type clamping block slideway 509, the guiding driving sprocket 510, the guiding driven sprocket 511, and the guiding chain tensioning bolt 5012.

[0017] The first storage and guiding mechanism assembly includes a meshing gear 503, a guiding semi-open chain-type clamping block group 504, a guiding clamping support 506, a guiding chain tensioning mechanism 507, a guiding semi-open chain-type clamping block slideway 509, a guiding driving sprocket 510, a guiding driven sprocket 511, and a guiding chain tensioning bolt 5012.

[0018] The two ends of the driving shaft are rotatably connected to the guiding mechanism support 502, and a meshing gear 503 and a guiding driving sprocket 510 are fixedly connected to the driving shaft.

[0019] The two ends of the driven shaft are respectively rotatably connected to the guiding chain tensioning mechanism 507, and a guiding driven sprocket 511 is fixedly connected to the driven shaft. The guiding semi-open chain-type clamping block group 504 meshes outside the guiding driving sprocket 510 and the guiding driven sprocket 511. The guiding chain tensioning mechanism 507 is in sliding limit fit with the guiding mechanism support 502. The guiding chain tensioning bolt 5012 is in threaded fit with the guiding mechanism support 502, and the guiding chain tensioning bolt 5012 abuts against the guiding chain tensioning mechanism 507. The distance between the same group of guiding driving sprocket 510 and guiding driven sprocket 511 is adjusted by rotating the guiding chain tensioning bolt 5012. The guiding semi-open chain-type clamping block group 504 is a closed-loop structure composed of a plurality of semi-open chain-type clamping block units 20801. The guiding semi-open chain-type clamping block slideway 509 is slidably connected to the inside of the guiding semi-open chain-type clamping block group 504, and the fixed surface of the guiding semi-open chain-type clamping block slideway 509 is fixedly connected to the guiding clamping support 506.

[0020] The number of the clamping force adjusting screws 505 is 2N (N≥1). The clamping force adjusting screws 505 pass through the guiding and clamping support 506 of the first storage and guiding mechanism assembly and are threadedly connected to the guiding and clamping support 506 of the second storage and guiding mechanism assembly. The clamping force adjusting screws 505 are used to adjust the distance between the two guiding and clamping supports 506, and further adjust the distance between the two opposite guiding semi-open chain-type clamping block slides 509. Driven by the guiding power motor 508, the meshing gears 503 of the first storage and guiding mechanism assembly and the meshing gears 503 of the second storage and guiding mechanism assembly rotate in opposite directions to each other, so that the rotation directions of the two guiding driving sprockets 510 are also opposite. The coiled tubing 9 is clamped by the two guiding semi-open chain-type clamping block groups 504, and the rotation torque of the guiding power motor 508 is used to push the coiled tubing 9 to move up and down in the form of frictional force.

[0021] The working principle and usage process of the present invention:

[0022] During use, the central section of the guiding semi-open chain-type clamping block group 504 of the first storage and guiding mechanism assembly and the second storage and guiding mechanism assembly clamps the coiled tubing section passing by. Then, the guiding power motor 508 drives the guiding semi-open chain-type clamping block group 504 on the guiding driving sprocket 510 and the guiding driven sprocket 511 to move in a cycle. Under the action of sufficient frictional force, the coiled tubing moves upward or downward, and is linked with the storage and injection mechanism 2, the automatic alignment mechanism 6 of the tubing sleeve, and the traction electric control trolley 7, so as to realize the storage, guiding and alignment actions of the coiled tubing 9.

[0023] The guiding chain tensioning bolt 5012 is in threaded fit connection with the guiding mechanism bracket 502. Its function is to rotate the guiding chain tensioning bolt 5012 to adjust the distance between the guiding driving sprocket 510 and the guiding driven sprocket 511 of the same group.

[0024] The clamping force adjusting screws 505 are used to adjust the distance between the guiding and clamping support 506 of the first storage and guiding mechanism assembly and the guiding and clamping support 506 of the second storage and guiding mechanism assembly, and further adjust the distance between the two opposite guiding semi-open chain-type clamping block slides 509. Thereby, the frictional force between the guiding semi-open chain-type clamping block group 504 and the coiled tubing is adjusted.
