Background Art

[0002] Currently, the application of coiled tubing is becoming more and more extensive. Especially for the multi - channel and multi - functional coiled tubing containing fiber optic 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 winches, they are convenient and fast to use. However, for the winches of multi - channel and multi - functional coiled tubing with electric cables, there are many problems in use and they cannot well meet the requirements. For this reason, a coiled tubing large - capacity storage and transportation device has been invented. However, the relatively elastic coiled tubing needs to be rotated to be stored in the pipe storage mechanism or taken out from the pipe storage mechanism, and at the same time, it needs to bear the weight of other mechanisms of the coiled tubing large - capacity storage and transportation device and the load from the coiled tubing. Such a slewing support mechanism is an essential component of the coiled tubing large - capacity storage and transportation device. Therefore, it is very necessary to invent the slewing support mechanism of the coiled tubing large - capacity storage and transportation device. Summary of the Invention

[0005] The slewing bottom plate is rotatably connected to the fixed seat through the slewing bearing. The slewing bottom plate is fixedly connected to the bottom ends of the four columns of the main body support. The main body support is respectively connected to the climbing cage, the second - layer platform, the top platform, the upper and lower sliding ways of the auxiliary clamping and lifting mechanism and the storage and injection mechanism clamping slide way. The limiting sliding bearing of the storage and injection power support frame and the pressure - bearing sliding bearing of the storage and injection power support frame are in rolling connection with the storage and injection mechanism clamping slide way;

[0006] The main body support is provided with a gooseneck reversing mechanism interface connected to the force sensor fixing plates on both sides of the gooseneck reversing mechanism, a storage and injection mechanism interface connected to the storage and injection mechanism, and also an upper interface of the auxiliary clamping and lifting mechanism connected to the auxiliary clamping and lifting mechanism, an interface of the pipe storage sleeve automatic alignment mechanism connected to the pipe storage sleeve automatic alignment mechanism, and an interface of the sleeve-type large-capacity pipe storage mechanism connected to the sleeve-type large-capacity pipe storage mechanism.

The function of the present invention is to support the gooseneck reversing mechanism 1, the storage and injection mechanism 2, the auxiliary clamping and lifting mechanism 4, and the coiled tubing 9. Driven by the traction electric control trolley 7, the upper rotating part rotates with the storage and guiding mechanism 5 and the pipe storage sleeve automatic alignment mechanism 6;

[0014] The slewing bottom plate 303 is rotatably connected to the fixed seat 301 through a slewing bearing 302.

When it is necessary to enter equipment or tools with a height close to that of the portal opening 3017 from the portal opening 3017, the opening reinforcing rod 309 of the slewing support mechanism is removed. The limiting sliding bearing 2010 and the pressure-bearing sliding bearing 2011 of the storage and injection power support frame are in rolling connection with the clamping slideway 3015 of the storage and injection mechanism, providing a slideway for horizontal movement.
