[0014] Combined with Figures 1-5 , a pipeline conveying device for shaft construction, comprising a guide end 1, a fixed structure 2, and a protective structure 3, wherein a connecting structure 5 is provided at the rear end of the guide end 1, the guide end 1 is connected to the fixed structure 2 through the connecting structure 5, and a protective structure 3 is installed outside the fixed structure 2; The guide end 1 includes a guide cone 11, a guide ball 12 is installed on one side of the guide cone 11, and a buffer end 13 is provided on the side of the guide cone 11 away from the guide ball 12; the guide ball 12 is installed at the end of the guide cone 11 with a threaded structure, which is easy to replace and install. The guide ball 12 needs to select a suitable diameter according to the gap angle of the support structure in the shaft, etc., which is mainly used to prevent the guide end 1 from being inserted into the gap of the support structure during the downward movement, affecting the downward transportation of the pipeline. The guide ball 12 is a consumable part at the front end. When the surface of the guide ball 12 is not smooth, a new guide ball 12 can be replaced to ensure good guiding and drilling seam release effects; the guide cone 11 is used to keep the guide ball 12 in the shaft channel through the interaction force such as friction between the conical surface and the support structure after the guide ball 12 contacts the support structure, so as to ensure correct guiding effect; the buffer end 13 is a spring-based telescopic support seat structure, which can buffer impact force and provide a certain supporting force. The buffer end 13 is used to contact the lower end of the pipeline to buffer the vibration impact generated by the friction and collision between the guide end 1 and the well wall and the supporting structure and transmit it to the pipeline end, thereby protecting the pipeline end from damage.

[0015] The protective structure 3 includes a rotating seat 31, which is fixedly connected to the fixed structure 2. A rotating rod 32 is rotatably mounted on the rotating seat 31.

Small rollers 34 are provided at the two ends of the elastic outer support rod 33 where they are rotatably connected to the rotating rod 32. A large roller 35 is rotatably mounted in the middle of the elastic outer support rod 33. The rotating seat 31 is provided with three outsides of a fixed belt 21.

[0016] The fixing structure 2 comprises a fixing belt 21, the rotating seat 31 is fixedly connected to the outside of the fixing belt 21, locking structures 22 are provided at both ends of the fixing belt 21, the surface of the fixing belt 21 is coated with a rubber layer 23, a plurality of fixing seats 24 are provided outside the fixing belt 21, a pull rod 25 is fixedly installed in the fixing seat 24, a threaded sleeve 26 is installed at one end of the pull rod 25 away from the fixing seat 24, and the pull rod 25 is connected to the pull rod 25 on the opposite side through the threaded sleeve 26; the fixing belt 21 as a whole is close to a semicircular strip-shaped metal strip; a group of the fixing structures 2 It includes at least two fixing belts 21, four fixing seats 24 and a pull rod 25. At least two groups of circularly symmetrical fixing structures 2 are installed on the outside of the pipeline; threads are respectively arranged on both sides of the pull rod 25, and a limit end is arranged at one end of the pull rod 25 inserted into the fixing seat 24. Two groups of symmetrical threads are arranged on both sides of the threaded sleeve 26. A through hole is opened in the middle of the threaded sleeve 26, and the through hole is used to insert tools such as a pry bar. When the threaded sleeve 26 rotates, the symmetrical thread structure enables the two pull rods 25 to move closer or farther away at the same time, thereby adjusting the distance between the two fixing belts 21 on the same side.

[0017] The locking structure 22 includes a locking piece 221, which is rotatably mounted in the curling edges at both ends of the fixing belt 21. A locking hole 220 is provided in the locking piece 221, and locking bolts 223 are installed in the locking holes 220 of two adjacent locking pieces 221. The locking bolts 223 are fixed by connecting with the locking bolt cap.

[0018] The rubber layer 23 is semi-enclosed and coated on the surface of the fixing belt 21. The side of the rubber layer 23 facing the installation pipeline is provided with a plurality of arc strips 230. The rubber layer 23 can increase the friction between the rubber layer 23 and the pipeline, improve the installation stability, and at the same time, the rubber layer 23 can also provide a good buffering effect; the arc strips 230 can increase the elastic deformation of the contact surface between the rubber layer 23 and the pipeline, bringing a better buffering effect.

[0019] The connection structure 5 includes a rotating seat 2 51, on which a support tube 52 is rotatably mounted, a telescopic rod 1 53 is arranged in the support tube 52, a spring in contact with the end of the telescopic rod 1 53 is arranged in the support tube 52, a connector 54 is rotatably mounted on the end of the telescopic rod 1 53, and the connector 54 is connected to the threaded end of the pull rod 25 passing through the fixed seat 24 through a threaded sleeve.

[0020] The elastic outer support rod 33 includes a middle rod barrel 331, and two sides of the middle rod barrel 331 are symmetrically slidably mounted with telescopic rods 332, and two sides of the middle rod barrel 331 are symmetrically mounted with springs in contact with the telescopic rods 332. The springs are low-rigidity springs, and when the pipeline and the device contact the inner wall of the well or the supporting structure, the springs deform in time to absorb the impact force, and after the springs are compressed, the spring force provides a strong support to the pipeline on that side.

[0021] When the device is in use, several groups of fixed structures 2 and protective structures 3 can be installed outside the pipeline. If the tubular material is transported, the device can be directly installed outside the tubular material, and several groups of protective structures 3 can be installed at a larger interval. If multiple wire materials are transported, multiple wires need to be placed in the wire support frame, and the device needs to be installed after bundling according to the hardness of the wires. When transporting wire materials, several groups of fixed structures 2 and protective structures 3 need to be installed at a smaller interval. By adjusting the installation spacing of the two groups of fixed belts 21, the distance between the elastic outer support rod 33 and the pipeline axis can be adjusted to adapt to wells of different diameters. The pipeline is transported to the well by hoisting and laying out the line with a hoist. Through the device, the guide end 1 can effectively guide the pipeline to be efficiently laid out and transported, and prevent the end of the pipeline from colliding. The protective structure 3 can effectively prevent the pipeline from being scratched and damaged by the well wall and the supporting structure. There is no need for excessive manual intervention in the transportation process, which improves construction efficiency, ensures construction safety and pipeline quality.
