Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically a self-propelled floating pipe transport device for large-diameter pipeline construction. Background Technology

[0002] When constructing large-diameter pipelines, if the construction area includes areas without roads such as coastal shallows, swamps, or dense water networks, it is very difficult to transport heavy large-diameter pipe sections from the prefabrication site to the laying site using heavy-duty trucks.

[0003] Currently, there is a floating pipe transportation technology. First, a transportation trench is dug from the pipe section prefabrication site to the burial site, and a traction device is built along the trench. Then, at the prefabrication site, end caps are welded to both ends of the large-diameter pipe section and steel wire ropes are tied to the end caps for traction. Then, the pipe section is placed into the trench and floats on the water using its own buoyancy. Then, the traction device is used to pull and transport each pipe section to the burial site. Finally, at the burial site, the end caps welded to both ends of the pipe section are cut off.

[0004] This floating pipe transportation technology has some shortcomings: the pipe sections are first welded to both ends and then cut off, which increases material costs and construction time; in addition, the construction of traction devices along the ditch increases construction difficulty and cost. Summary of the Invention

[0005] To address the technical problems mentioned in the background above, this utility model provides a self-propelled floating pipe transport device for large-diameter pipeline construction. It eliminates the need for welding end caps at both ends of the pipe section, and the steel pipe can navigate autonomously without the need to construct a traction device along the ditch, thereby reducing construction difficulty and saving construction costs and time.

[0006] Technical solution: A self-propelled floating pipe transport device for large-diameter pipeline construction, comprising a propulsion frame set at the rear end of the steel pipe, a guide frame set at the front end of the steel pipe, and several floats set on both sides of the steel pipe; The main body of the propulsion frame is designed with three legs. A circular propulsion motor base is located in the middle of each of the two lower legs, and a propulsion end pressure block is welded to the lower end of each lower leg, supporting it on the inner wall of the steel pipe. A set screw seat with two right-hand threaded holes is welded to the upper end of the upper leg. Two bidirectional set screws are connected to the right-hand threaded holes of the set screw seat, and the bidirectional set screws are configured with a left-hand thread at the top and a right-hand thread at the bottom. A movable pressure block is connected to the upper part of the bidirectional set screws, and two left-hand threaded blind holes are machined on the movable pressure block, which is supported and pressed against the inner wall of the steel pipe by the bidirectional set screws. Two waterproof motors are horizontally mounted on the propulsion motor base of the propulsion frame, and a propeller is mounted on the shaft of each waterproof motor as the propulsion power source. The guide frame is shaped like an A-beam. A circular plate-shaped geared motor base is located in the middle of the A-beam, and a guide end pressure block is welded to the lower ends of each of the two inclined beams, supporting the inner wall of the steel pipe. A cross-shaped support plate is welded to the upper end of the A-beam. Two right-hand threaded holes are machined at the rear end of the support plate inside the steel pipe, and a small mounting hole is machined at the front end outside the steel pipe. A pin hole is machined at each of the left and right ends of the support plate outside the steel pipe. A geared motor is vertically mounted on the geared motor base of the guide frame, and a rudder is mounted on the lower shaft of the geared motor to control the direction of travel. Two bidirectional set screws are connected to the two right-hand threaded holes at the rear end of the support plate of the guide frame, and the movable pressure block is connected to the upper part of the bidirectional set screws, supporting and pressing against the inner wall of the steel pipe. Two small brackets are installed on the pin holes at both ends of the support plate of the guide frame. Each small bracket includes a pin shaft and a small plate. The pin shaft and the pin hole are designed to fit tightly, and the small bracket can remain stationary after the tilt angle is adjusted. Radar holes are machined on the small plates of the small brackets, and a range-detecting radar is installed on each one. A control system is installed at the small hole at the front end of the support plate of the guide frame. The control system includes a control circuit, a remote control antenna, and two start / stop remote controllers. The control circuit receives signals from the range-detecting radar and the remote controllers, and controls the start / stop of the waterproof motor and the geared motor, as well as the direction of the geared motor. One set of the two remote controllers is placed at the steel pipe sending site, and the other set is placed at the steel pipe receiving site. The pontoon is a hollow cylinder made of plastic, with four tethering lugs on one side; the number of pontoons is set to several, and each pair of pontoons is tied to both sides of the steel pipe with four binding straps to ensure that the upper part of the steel pipe floats on the water surface. A set of waterproof batteries is installed at the bottom of the inner wall at both the front and rear ends of the steel pipe to provide power; all electrical components and wires are waterproofed.

[0007] Furthermore, the push end pressure block of the push frame, the guide end pressure block of the guide frame, and the two movable pressure blocks are all configured with a boss structure, which is close to the end face of the steel pipe to prevent the push frame and the guide frame from falling off.

[0008] Furthermore, a rubber pad is glued to the contact parts of the push end pressure block of the push frame, the guide end pressure block of the guide frame, and the two movable pressure blocks that are in contact with the inner wall of the steel pipe to avoid damage to the inner wall of the steel pipe when pressing.

[0009] Furthermore, the two waterproof motors are configured to rotate in opposite directions to balance the torque between them and prevent the steel pipe from rotating during operation.

[0010] Furthermore, the base of each set of waterproof batteries is attached to the inner wall of the steel tube by a pair of magnets for easy disassembly.

[0011] Compared with existing background technologies, the above-described at least one technical solution adopted in one or more embodiments of this specification can achieve the following beneficial effects: First, the self-propelled floating pipe transport device does not require welding end caps to both ends of the steel pipe. Buoyancy is provided by the pontoons, which can be reused, saving material costs. Furthermore, the number of pontoons can be increased or decreased to adjust the draft of the floating steel pipe, adapting to different ditch depths. Second, the self-propelled floating pipe transport device can navigate on its own, eliminating the need for additional traction devices along the ditch, reducing construction difficulty, and saving costs and time. Finally, the self-propelled floating pipe transport device is dispatched from the steel pipe prefabrication site and received at the burial site, eliminating the need for personnel to track and control the intermediate journey, thus saving manpower.
