Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1: Referring to Figures 1 - 5 as shown, an intelligent special loading and unloading vehicle for tubing and sucker rod is used in conjunction with a tubing and sucker rod transportation device.

[0029] An intelligent special loading and unloading vehicle for tubing and sucker rod includes a base 1, and wheels 2 are installed at the lower end of the base 1.

[0030] A rectangular frame 3 is fixed to the upper end of the base 1, and a lifting frame 5 is slidably arranged in the vertical direction within the frame 3. Specifically, sliding sleeves 4 are sleeved on the columns of the frame 3, and the sliding sleeves 4 are fixedly connected to the lifting frame 5.

[0031] At the upper end of the base 1 below the lifting frame 5, an oil stain storage box 17 is fixedly installed. The oil stain storage box 17 can collect the oil stains on the oil pipe or the sucker rod, and can prevent the oil stains from falling to the ground.

[0032] A plurality of vertical lower oil cylinders 6 are fixedly installed on the base 1, and the upper ends of the lower oil cylinders 6 are fixedly connected to the lifting frame 5.

[0033] A sliding rod 11 is slidably arranged at the upper end of the lifting frame 5. Specifically, a plurality of guide rails 10 are fixedly installed on the lifting frame 5. The length direction of the guide rails 10 is perpendicular to the traveling direction of the base 1, and the sliding rod 11 is slidably connected to the guide rails 10.

[0034] The length direction of the sliding rod 11 is perpendicular to the traveling direction of the base 1. A bracket 7 is arranged at the upper end of the sliding rod 11. The bracket 7 is parallel to the lifting frame 5. One end of the bracket 7 away from the oil pipe and sucker rod transportation device is rotatably connected to the sliding rod 11. Specifically, one end of the bracket 7 away from the oil pipe and sucker rod transportation device is rotatably connected to the sliding rod 11 through a hinge 13.

[0035] A plurality of vertical upper oil cylinders 8 are fixedly installed at the end of the lifting frame 5 close to the oil pipe and sucker rod transportation device. After the upper oil cylinders 8 extend, they can drive the bracket 7 to turn over.

[0036] A driving unit capable of driving the sliding rod 11 to move is arranged on the lifting frame 5. The driving unit includes a hydraulic rod 15. The hydraulic rod 15 is parallel to the sliding rod 11. One end of the hydraulic rod 15 is fixedly connected to the lifting frame 5, and the other end of the hydraulic rod 15 is fixedly connected to the sliding rod 11 through a connecting plate 12.

[0037] Pushing components are arranged at both the left and right ends of the bracket 7. The pushing components can push the oil pipe or the sucker rod on the bracket 7 out.

[0038] The oil pipe or the sucker rod on the bracket 7 is located between the two pushing components. The axial direction of the oil pipe or the sucker rod on the bracket 7 is parallel to the traveling direction of the base 1.

[0039] The pushing component includes a telescopic rod 14. The telescopic rod 14 is parallel to the sliding rod 11. One end of the telescopic rod 14 is fixedly installed on the bracket 7, and the other end of the telescopic rod 14 is fixedly connected to a push plate 9.

[0040] The push plate 9 includes a longitudinal part in the middle and flat parts at the front and rear ends. The flat parts at the front and rear ends of the push plate 9 are arranged in a left-right staggered manner. The telescopic rod 14 is fixedly connected to the flat part at the rear side of the push plate 9, and the flat part at the front side of the push plate 9 blocks the end of the oil pipe or the sucker rod on the bracket 7.

[0041] During operation, park this loading and unloading vehicle on one side of the tubing and sucker rod transportation device, and then start the upper oil cylinder 8 to cause the bracket 7 to turn upwards towards one end of the tubing and sucker rod transportation device. Place the tubing or sucker rod on the bracket 7 in sequence, and make the tubing or sucker rod located between the two pushing components. Since the bracket 7 is in an inclined state, after the tubing or sucker rod is placed on the bracket 7, it can roll towards the side away from the tubing and sucker rod transportation device under its own weight.

[0042] The straight part on the front side of the push plate 9 can block the end of the first tubing or sucker rod entering the bracket 7, and the subsequent tubing or sucker rod entering the bracket 7 is blocked by the previously entered tubing or sucker rod on the bracket 7.

[0043] Start the lower oil cylinder 6, and the lifting frame 5, the bracket 7 and the tubing or sucker rod on the bracket 7 can move up and down. When the lifting frame 5 and the bracket 7 reach the appropriate height, start the hydraulic rod 15, so that the hydraulic rod 15 makes the bracket 7 and the tubing or sucker rod thereon close to the tubing and sucker rod transportation device through the connecting plate 12 and the sliding rod 11. Then retract the upper oil cylinder 8 to make the bracket 7 parallel to the lifting frame 5, and control the height of the lifting frame 5 and the bracket 7 so that the upper end of the bracket 7 is flush with the lower end of the storage cavity where the tubing or sucker rod needs to enter the tubing and sucker rod transportation device. Then start the telescopic rod 14, so that the telescopic rod 14 drives the push plate 9 to drive multiple tubing or sucker rods on the bracket 7 to move into the storage cavity of the tubing and sucker rod transportation device. After all the tubing or sucker rods on the bracket 7 enter the storage cavity of the tubing and sucker rod transportation device, just make the telescopic rod 14 drive the push plate 9 to return to its original position.

[0044] During the process of transferring the tubing or sucker rod to the bracket 7, after starting the hydraulic rod 15, the sliding rod 11 can drive the bracket 7 away from the tubing and sucker rod transportation device, which is convenient for placing the tubing or sucker rod on the bracket 7 from the front side of this loading and unloading vehicle.

[0045] The lower oil cylinder 6, the upper oil cylinder 8, the telescopic rod 14 and the hydraulic rod 15 are all connected to the hydraulic station through high-pressure pipelines, and the solenoid valves controlling the lower oil cylinder 6, the upper oil cylinder 8, the telescopic rod 14 and the hydraulic rod 15 are all electrically connected to the plc controller. The plc controller can intelligently control the actions of the lower oil cylinder 6, the upper oil cylinder 8, the telescopic rod 14 and the hydraulic rod 15 through its built-in program.

[0046] Embodiment 2: On the basis of Embodiment 1, with reference to Figure 1 、 Figure 3 and Figure 4 as shown, fixed pipes 16 are fixedly arranged on the left and right sides of the lower end of the frame 3, and the inserted pipes movably arranged on the tubing and sucker rod transportation device can be inserted into the fixed pipes 16.

[0047] After the movable insertion tube on the tubing and sucker rod transportation device is inserted into the fixed tube 16, it can support and position the tubing and sucker rod transportation device and this loading and unloading vehicle.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
