Description

Technical Field

[0001] The utility model relates to a tool for outdoor heating cable construction, in particular to a self-balancing heating cable winding mechanism, belonging to the technical field of heating cable construction. Background Art

[0002] Waxy heavy oil has high freezing point and viscosity, and has large friction resistance in wellbore and trunk line, so it needs to be produced by reducing viscosity. The solubility of crude oil in wax decreases with the decrease of temperature. During the crude oil transportation process, when the temperature drops to a value where the solubility of crude oil in wax is less than the wax content of crude oil, the wax dissolved in the crude oil begins to precipitate and adhere to the inner wall of the oil pipeline. At present, the gathering and transportation pipeline mainly relies on medium frequency cables for heating to reduce the viscosity of crude oil and improve the transportation capacity.

[0003] The commonly used model of medium frequency heating cable is ZR-YJV0.6 / 11×25, the conductor is copper core or aluminum core, the insulation layer is cross-linked polyethylene insulation, the outer periphery is polyvinyl chloride sheath, the withstand voltage is 600--1000V, it is a flame-retardant low-voltage power cable, the single core area is 25mm², it is wound on a large cable drum used for factory packaging, and a large cable drum is wound with more than 500 meters of medium frequency heating cable. Traditionally, the winding of medium frequency heating wire is done manually, which is not only time-consuming and labor-intensive, but also inefficient and difficult to meet long-distance construction.

[0004] The Chinese invention patent application with publication number CN117326411A discloses an automatic winding walking device for medium-frequency heating cables in oil pipelines, including: a clamping walking mechanism, which is clamped around the outer periphery of the jacket tube and moves forward at a constant speed; a cable winding mechanism, which winds the medium-frequency heating cable around the outer periphery of the jacket tube while the clamping walking mechanism moves forward; a sheet metal box body, which accommodates and supports the clamping walking mechanism and the cable winding mechanism. The clamping walking mechanism includes: a top longitudinal bracket, which is located at the top of the jacket tube, and the axis is parallel to the axis of the jacket tube; active walking wheels, which are installed below the two ends of the top longitudinal bracket and are respectively supported on the top of the jacket tube; a bottom longitudinal bracket, which is symmetrically located on both sides of the bottom of the jacket tube and is distributed in an isosceles triangle with the top longitudinal bracket; and bottom walking wheels, which are installed at both ends of the corresponding bottom longitudinal bracket and respectively abut against the bottom of the jacket tube.

[0005] This technical solution has the following defects: 1. The cable drum installation shaft is installed vertically and fixed on the outer end surface of the winding rotating disk and extends outward in a cantilevered manner. It can only be used to wind delicate cables. The medium-frequency cable with larger specifications is too heavy and is hung at the front end of the tool, which brings a large overturning moment along the axial direction;

[0006] 2. The distance between the cable drum installation axis and the jacket tube is small, which limits the outer diameter of the small cable reel. The winding length of a single cable is not enough. The small radius of the small cable reel makes it difficult to pre-wind the slightly thicker intermediate frequency cable.

[0007] 3. When the turntable opening is facing downward, the cable drum installation axis is located at the top of the winding rotating disk, resulting in a heavier cable drum located at the highest position of the tooling, which is an unstable balance state. As the tooling moves forward, it is easy to rotate the entire tooling 180°, causing the direction of the operating screen to be reversed, and causing the notch of the turntable to be subjected to force due to being upward;

[0008] 4. The walking mechanism is driven by dual motors, which may cause interference and waste battery power due to the error of front and rear speeds;

[0009] 5. The winding servo motor is located on one side of the housing, which makes the weight distribution of the entire tooling unbalanced and brings a certain amount of additional torque to the tooling. Utility Model Content
