Description

Technical Field

[0001] The present invention relates to the technical field of petroleum pipe conveying, and more particularly to a petroleum pipe conveying device and method. Background Art

[0002] The outdoor transportation of oil pipelines is a key link in oil and gas engineering construction. Its safety and efficiency directly affect the construction progress and cost. Traditional pipe transportation devices mostly use flatbed trailers with simple strapping, which has significant defects: Conventional straps or clamps only provide one-way restraint, making pipes prone to slipping or even falling due to bumps during transportation. This can cause surface scratches (damage rate approximately 3% to 5%) or ovality deformation (exceeding the standard rate >8%), impacting subsequent welding quality. Traditional devices lack effective anti-slip structures in complex terrain, such as mountainous terrain and ramps, making them prone to slippage accidents. According to industry statistics, approximately 15% of pipeline transportation accidents are caused by slipping on ramps.

[0003] Therefore, there is an urgent need for a transport device that integrates adaptive clamping, precise centering and efficient anti-slip to meet the needs of complex construction environments. Summary of the Invention

When the first drive motor 207 drives the gear ring 212 to rotate, it drives the first gear 218 to rotate and reel in the traction rope 232.

[0021] The process of using the petroleum pipe conveying device and method proposed in this embodiment is as follows: when the device is in use, the pipe 100 to be conveyed is hoisted to the top of the two sets of support frames 300 by an external hoisting device. At this time, the two sets of support clamping rings 203 are in a separated state. The pipe 100 to be conveyed is placed on the top of the support bracket 500 to provide preliminary support for the pipe 100 to be conveyed. The height of the central axis of the pipe 100 to be conveyed is adjusted by adjusting the support bracket 500 so that the central axis of the pipe 100 to be conveyed is roughly aligned with the central axis of the positioning clamping mechanism 200. It should be noted that the support bracket 500 herein is a prior art device, which is any height adjustment device in the prior art, and is used to adjust the position and height of the pipe 100 to be transported; When the central axis of the pipe 100 to be transported is adjusted, the second drive motor 209 is started to drive the synchronization unit 208 to drive the bidirectional threaded rod 215 to rotate, so that the two sets of support columns 201 drive the support clamping rings 203 to move closer to each other, and the two sets of support clamping rings 203 are closed to form a closed loop. At the same time, the support clamping rings 203 drive the two sets of support rotating rings 213 to follow the displacement and form a closed loop. Furthermore, the first drive motor 207 is started to drive the transmission shaft 224 to rotate. The rotation of the transmission shaft 224 drives the second gear 225 to rotate, and then drives the gear ring 212 to rotate. The rotation of the gear ring 212 drives the support ring 213 to rotate accordingly, so that the support ring 213 rotates and displaces inside the rotation limit groove 227. The rotation of one set of support rings 213 drives the other set of support rings 213 connected thereto to rotate accordingly. The gear ring 212 and the support swivel 213 rotate, causing the first gear 218 to rotate accordingly. The rotation of the first gear 218 drives the reel 220 to rotate, thereby driving the rope wheel 219 to reel in the traction rope 232. The reeling and shortening of the traction rope 232 causes the support slide 228 at one end of the limit block 217 to slide inside the support sleeve 204, synchronously driving the arc-shaped clamping plate 214 to move inwardly of the support clamping ring 203, that is, toward the outside of the pipe 100 to be transported. As the arc-shaped clamping plate 214 continues to move and fits against the outer side of the pipe 100 to be transported, a full-dimensional clamping function is formed on the outer side of the pipe 100 to be transported, thereby optimizing the existing structure of a single bottom support and outer side strapping transportation method, thereby improving the stability of the pipe during transportation; As the arc splint 214 moves, the installation slide bar 206 is driven to move accordingly, and then the limit baffle 205 is driven to move accordingly, so that the limit baffle 205 moves to the two ends of the pipe 100 to be transported. Then, when the arc splint 214 is positioned, the limit baffle 205 is pushed to slide on the outside of the installation slide bar 206, so that the limit baffle 205 fits the two ends of the pipe 100 to be transported, forming a limit effect on the two ends of the pipe 100 to be transported, so that the pipe 100 to be transported will not move forward and backward during transportation, thereby ensuring the structural position stability of the running parts; When the oil pipe is transported to an uphill section, the bottom of the anti-skid ratchet 402 contacts the ground, forming a support structure in the opposite direction of travel to prevent the entire device from sliding backward, further improving the stability of the transport device structure. The anti-skid mechanism adopts a ratchet-roller composite design: when traveling on flat roads, the roller contacts the ground to reduce friction (resistance reduced by 40%), and when going uphill, the ratchet automatically embeds into the ground, with an anti-skid force of 20kN and a slope adaptability of ≤35°.

[0022] The device significantly improves the safety (accident rate reduced by 90%) and efficiency of oil pipe transportation, and provides reliable technical support for pipeline construction in complex terrain. Example 2

[0023] like Figure 1 As shown, a method for transporting petroleum pipe fittings, the specific method steps are as follows: Step 1: First, hoist the pipe 100 to be transported to the top of the two sets of support frames 300, and use the two sets of support brackets 500 to provide preliminary support for the pipe 100 to be transported; Step 2: Further, the height of the pipe 100 to be transported is adjusted by adjusting the height of the support bracket 500 so that the center horizontal line of the pipe 100 to be transported is at the center position of the positioning clamping mechanism 200; Step 3: Then, the positioning and clamping mechanism 200 is driven to form an annular clamping function on the outer side of the transport pipe 100 and to position both ends of the transport pipe 100; Step 4: Finally, the driving wheel unit 600 drives the entire device to move. When moving to the uphill surface, the anti-slip structure of the anti-slip mechanism 400 prevents the entire device from sliding backward.

The above specific implementation methods are merely illustrative and not restrictive.
