Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, specifically to pipeline transportation devices. Background Technology

[0002] The pipeline laying and installation process involves a large number of pipelines. Before the construction of formal roads or in confined spaces, installation site conditions are poor, making it difficult for large vehicles to access the pipelines. Pipeline transportation at the installation site typically relies on loaders or manual handling. The pipelines must undergo several loading and unloading operations from the centralized storage warehouse to the installation location. Furthermore, during installation, within the confined space of crane operations, manual handling or manual hoisting is essential, resulting in significant manpower and material costs, slow construction speed, and high construction costs.

[0003] Patent document CN210620059U discloses a pipeline hoisting and transportation device for installation sites, including a flatbed frame, axles, tires, a tow bar, hollow columns, railings, a triangular hoist, a fixed pulley, an electric winch, a wire rope, a hook, and two bearings. The axles are located on the bottom surface of the middle part of the flatbed frame, the tires are located at both ends of the axles, the tow bar is located on the bottom surface of the front side of the flatbed frame, the railings are vertically spaced on both sides of the top surface of the flatbed frame, the hollow columns are vertically spaced on the top surface of the rear of the flatbed frame, the two bearings are spaced apart at the lower part of the vertical rod of the triangular hoist, the vertical rod of the triangular hoist, together with the two bearings, is inserted into the hollow column, the fixed pulley is located at the front end of the horizontal rod of the triangular hoist, the electric winch is located at the connection between the vertical rod and the diagonal rod of the triangular hoist, and the wire rope passes through the fixed pulley, with its rear end connected to the electric winch and its front end connected to the hook. During pipeline installation, this device is parked at the pipeline storage area. Its built-in lifting and slewing mechanism is used to hoist the pipeline onto a flatbed truck, which is then towed to the installation site. The built-in lifting and slewing mechanism is then used again to lower the pipeline to the installation location. However, this device utilizes a lifting and slewing mechanism to lift the pipeline, which poses safety hazards during the lifting process. Furthermore, the lifting and slewing mechanism mounted on the flatbed truck has a limited lifting capacity and is unsuitable for lifting large-diameter pipelines.

[0004] Patent document CN220535661U discloses a pipeline transport trolley, including a trolley body with at least one set of fixing slots for accommodating pipelines. By using these fixing slots to secure the pipeline, the cumbersome steps of disassembling and assembling retaining posts and wire ropes are eliminated. However, this transport trolley relies on manual power for pipeline transport and is not suitable for transporting long pipelines. Utility Model Content

[0005] The main purpose of this utility model is to provide a pipeline transportation device that facilitates the transfer of pipelines to trailers, ensures high safety during the pipeline transfer process, and facilitates pipeline unloading.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] The pipeline transport device includes a tractor connected to a trailer. The height of the upper front end of the trailer is greater than the height of the upper rear end. A drive unit is installed on the front of the trailer, with its axial direction parallel to the length direction of the trailer. Two pulleys are fixed on the drive unit, and steel wire ropes are wound on the pulleys. One end of the steel wire rope is fixedly connected to the pulley, and the other end of the steel wire rope is a closed loop. The upper end of the trailer has grooves corresponding to the pulleys, which extend in the width direction of the trailer. Multiple mounting slots are provided on the upper rear end of the trailer, and a swing arm is rotatably connected in the mounting slot. The swing arm includes a support part, and a guide part perpendicular to it is fixed at the rear end of the support part. The guide part extends upward, and the upper end of the support part is flush with the upper end of the trailer. After the swing arm rotates towards the rear of the trailer, the guide part contacts the ground. When the steel wire rope pulls the pipeline to the upper end of the trailer, the guide part can guide the pipeline. After the pipeline is pulled to the upper end of the trailer, the pipeline can pass through the support part to cause the swing arm to rotate and return to its original position.

[0008] Specifically, the trailer includes a rectangular ring-shaped frame, with wheel sets installed on both the left and right sides of the lower end of the frame, and a tow bar fixed to the left end of the frame, which is rotatably connected to the tow truck of the tractor.

[0009] Specifically, the frame has multiple inner rods fixed inside, and the axial direction of the inner rods is parallel to the width direction of the frame.

[0010] Specifically, a support rod is fixed inside the frame, which can block the lower end of the support part of the swing arm.

[0011] Specifically, the swing arm is rotatably mounted in the mounting groove via a pivot pin.

[0012] Specifically, multiple stop levers are fixed to the upper front side of the trailer.

[0013] Specifically, the drive device includes a drive unit fixed to the front side of the trailer. A rotating shaft is rotatably mounted on the front side of the trailer. The axial direction of the rotating shaft is parallel to the length direction of the trailer. A rope pulley is concentrically mounted and fixed on the rotating shaft. The drive unit is connected to the rotating shaft via a reducer.

[0014] Specifically, the drive unit is a hydraulic motor, which is connected to the hydraulic system of the tractor unit via a directional valve and oil pipes. After the hydraulic system of the tractor unit is started, the hydraulic motor can be driven to rotate forward and backward through the directional valve.

[0015] Specifically, the drive unit is a motor, which is connected to the battery pack on the trailer via a controller. The battery pack provides power to the motor, and the controller can change the direction of rotation of the motor.

[0016] Specifically, the support part and the support rod of the swing rod are provided with concentric through holes, the axis of the through holes is perpendicular to the axis of the support part, and the pin passes through the through holes on the support part and the support rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The rotatable swing arm guide design automatically adjusts its angle to form a ramp guide surface when the pipeline is pulled onto the trailer or unloaded by the wire rope, avoiding the risk of pipeline swaying in traditional hoisting. The guide part forms a smooth transition when it contacts the ground, which reduces collision damage between the pipeline and the edge of the trailer and significantly reduces the need for manual ramp adjustment, making it especially suitable for the smooth loading and precise unloading of large-diameter pipelines.

[0019] 2. The support part of the swing arm automatically rotates and resets after the pipeline is in place. When the vehicle returns empty, the pin can prevent the swing arm from swinging, ensuring high safety when returning empty.

[0020] 3. The drive unit offers both hydraulic motor and electric motor options to meet the compatibility requirements of different traction equipment. The symmetrical layout of the rope pulley and groove ensures even distribution of wire rope tension. Combined with the reducer, it precisely controls the traction speed, solving the problem of easy skew due to single-point force in traditional winches. It is particularly suitable for synchronous traction operations on ultra-long pipelines.

[0021] 4. The trailer's tilted design, with a higher front and lower rear, combined with an internal reinforced frame, lowers the overall center of gravity while ensuring structural strength. This allows it to navigate narrow construction passages, eliminating reliance on large lifting equipment. It is suitable for short-haul pipeline transport on unpaved roads or in temporary construction scenarios, significantly expanding its application scope. During pipeline unloading, the trailer's tilted design allows the pipeline to slide down automatically, facilitating unloading.

[0022] 5. The entire process of traction loading, automatic guidance, and unloading sliding is mechanized, replacing traditional high-risk operation modes such as manual handling and hoist lifting. Operators only need to control the start and stop of the drive device to complete single-person multi-pipe transportation, reducing manpower input by more than 70%, and completely avoiding safety hazards such as broken hoisting wire ropes and pipes falling from heights.

[0023] 6. The inclined surface formed by the front side of the trailer being higher than the rear side allows the pipe to naturally fit snugly against the trailer, limiting the pipe's movement to the travel axis and eliminating the pipe's tendency to roll in the width direction of the trailer due to inertia or bumps.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1: Refer to Figures 1-4 As shown, the pipeline transport device includes a tractor 1 connected to a trailer 2.

[0031] The trailer 2 includes a rectangular ring-shaped frame with multiple inner rods 15 fixed inside. The axial direction of the inner rods 15 is parallel to the width direction of the frame. Wheel sets are installed on both the left and right sides of the lower end of the frame. A tow bar 3 is fixed to the left end of the frame and is rotatably connected to the towing card of the tractor 1.

[0032] The height of the upper front side of trailer 2 is greater than the height of the upper rear side. Multiple stop bars 10 are fixed to the upper front side of trailer 2.

[0033] A drive unit is provided on the front side of the trailer 2. The axial direction of the drive unit is parallel to the length direction of the trailer 2. Two pulleys 7 are fixed on the drive unit.

[0034] The drive unit includes a drive unit fixed to the front side of the trailer 2. A rotating shaft 6 is rotatably mounted on the front side of the trailer 2. The axial direction of the rotating shaft 6 is parallel to the length direction of the trailer 2. A rope pulley 7 is concentrically mounted and fixed on the rotating shaft 6. The drive unit is connected to the rotating shaft 6 through a reducer 5.

[0035] The drive unit is a hydraulic motor 4, which is connected to the hydraulic system of the tractor 1 via a reversing valve and oil pipes. After the hydraulic system of the tractor 1 is started, the hydraulic motor 4 can be driven to rotate forward and backward through the reversing valve.

[0036] A steel wire rope 9 is wound on the rope wheel 7. One end of the steel wire rope 9 is fixedly connected to the rope wheel 7, and the other end of the steel wire rope 9 is a closed rope loop.

[0037] The upper end of the trailer 2 is provided with a groove 8 corresponding to the rope wheel 7. The groove 8 extends in the width direction of the trailer 2. Multiple mounting slots 11 are provided on the upper rear side of the trailer 2. A swing rod 12 is rotatably connected in the mounting slot 11. The swing rod 12 is rotatably set in the mounting slot 11 through a pivot pin 13.

[0038] The swing arm 12 includes a support portion, and a support rod 14 is fixed inside the frame. The support rod 14 can block the lower end of the support portion of the swing arm 12. A guide portion perpendicular to it is fixed at the rear end of the support portion. The guide portion extends upward, and the upper end of the support portion is flush with the upper end of the trailer 2.

[0039] After the swing arm 12 rotates to the rear of the trailer 2, the guide part contacts the ground. When the wire rope 9 pulls the pipe 16 to the upper end of the trailer 2, the guide part can guide the pipe 16. After the pipe 16 is pulled to the upper end of the trailer 2, the pipe 16 can cause the swing arm 12 to rotate back to its original position through the support part.

[0040] When loading pipe 16, the trailer 2 is positioned in front of pipe 16 by the tractor 1, and the swing arm 12 is rotated so that the free end of the guide portion of the swing arm 12 contacts the ground. At this time, the guide portion of the swing arm 12 is tilted.

[0041] Start the hydraulic motor 4. The hydraulic motor 4 causes the shaft 6 and the rope wheel 7 to rotate through the reducer 5 and unwind the wire rope 9. After the wire rope 9 is unwound, the rope loops of the wire rope 9 on both sides are placed on both ends of the pipe 16.

[0042] Start the hydraulic motor 4. The hydraulic motor 4 causes the shaft 6 and the rope wheel 7 to rotate through the reducer 5 and wind up the wire rope 9. During the winding process of the wire rope 9, the pipe 16 is pulled towards the upper end of the trailer 2. The guide part of the swing arm 12 can guide the pipe 16, so that the pipe 16 can be gradually pulled to the upper end of the trailer 2.

[0043] After the pipe 16 is pulled to the upper end of the trailer 2, the pipe 16 can cause the swing arm 12 to rotate and return to its original position through the support.

[0044] The height of the upper front end of the trailer 2 is greater than the height of the upper rear end. Under its own weight, the pipe 16 tends to roll in the rear direction. During the transportation of the pipe 16, it can prevent the pipe 16 from rolling along the width direction on the upper end of the trailer 2.

[0045] When unloading pipe 16, start hydraulic motor 4. Hydraulic motor 4, through reducer 5, causes shaft 6 and rope wheel 7 to rotate and unwind wire rope 9. Since the height of the upper front end of trailer 2 is greater than the height of the upper rear end, pipe 16 can slide backward on the upper end of trailer 2 when wire rope 9 is unwound. When pipe 16 contacts the guide part of swing arm 12, the swing arm 12 can swing as pipe 16 moves backward on trailer 2. The guide part contacts the ground, and the guide part of swing arm 12 can guide pipe 16 as it moves backward on trailer 2. After pipe 16 moves to the ground, separate the rope loop of wire rope 9 from pipe 16 and then wind wire rope 9.

[0046] Example 2: Based on Example 1, the drive unit is a motor. The motor is connected to the battery pack on the trailer 2 through a controller. The battery pack provides power to the motor, and the controller can change the rotation direction of the motor.

[0047] The motor drives the rotating shaft 6 to rotate through the reducer 5, eliminating the need for the hydraulic system of the tractor 1 and allowing for easy replacement of different types of tractors 1.

[0048] Example 3: Based on Example 1, referring to... Figure 3 As shown, the support part of the rocker arm 12 and the support rod 14 are provided with concentric through holes, the axis of the through holes is perpendicular to the axis of the support part, and the pin 17 passes through the through holes on the support part and the support rod 14.

[0049] When the pipeline 16 is unloaded and the vehicle needs to return empty, the swing arm 12 is rotated to reset, and the pin 17 passes through the hole on the support and the bracket 14. When the vehicle returns empty, the pin 17 can prevent the swing arm 12 from swinging.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
