[0002] In the field of oil extraction, the tubing string includes oil pipes and sucker rods. Tubing and sucker rods are two different tubing string components that play a key role in the operation of oil wells. The tubing string is a narrow diameter pipe that is usually used inside an oil well to transport crude oil or natural gas from the bottom of the well to the ground. The tubing string is a part of the oil well that is installed below the oil layer and is used to transport oil or gas underground to the ground. The sucker rod is a long steel rod that is usually used in mechanical pumping wells. They are connected to the ground pumping unit (usually a device commonly known as a "pumping horse head") and the pump downhole. The tubing string is mainly responsible for transporting oil and gas, while the sucker rod is a key component that transmits power to drive the downhole pump.

[0032] like Figures 1 to 4 As shown, a pipe transfer and conveying device comprises a conveying swing arm mechanism 1 and a feeding mechanism 2;

[0033] The conveying swing arm mechanism 1 is used to lift the pipe column from the catwalk, pass other mechanisms to send the pipe column to the loading mechanism 2, or receive the pipe column on the loading mechanism 2 and put it on the catwalk; the loading mechanism 2 is used to receive the pipe column on the conveying swing arm mechanism 1 and send it to the front end of the pipe column track, or receive the pipe column from the front end of the pipe column track and transfer it to the conveying swing arm mechanism 1. The intelligent suspension conveying system composed of the conveying swing arm mechanism 1 and the loading mechanism 2 realizes the automatic conveying of the pipe column from the catwalk to the front end of the pipe column track, improving the working efficiency and working safety.

[0034] The conveying swing arm mechanism 1 is a four-bar mechanism, including a swing arm 11, a swing arm 12, a conveying hand 13 and a cylinder 14; one end of the swing arm 11 can be rotatably connected to the base 3, and the other end can be rotatably connected to the middle part of the conveying hand 13; one end of the swing arm 12 can be rotatably connected to the base 3, and the other end can be rotatably connected to the rear part of the conveying hand 13; one end of the cylinder 14 can be rotatably connected to the base 3, and the other end can be rotatably connected to the middle part of the swing arm 11.

[0035] The swing arm 11 and the swing arm 2 12 are configured to be L-shaped, and their function is to keep the conveying arm 13 always upward during movement.

[0036] As the main component of the four-bar mechanism, the swing arm 11 forms a stable rotatable connection with the conveying hand 13 and the base 3. Driven by the oil cylinder 14, the swing arm 11 can change its angle, so that the conveying hand 13 can move up and down, pick up the pipe column from the catwalk and lift it to a suitable position, or put the pipe column down on the catwalk.

[0037] The swing arm 2 12 is also an important part of the four-bar mechanism, connected to the conveying hand 13 and the base 3. It works in conjunction with the swing arm 1 11 to jointly ensure the stability and reliability of the conveying hand 13 during movement, so that the pipe string remains stable during the conveying process.

[0038] The conveying hand 13 is opened upwards and is used to hold the pipe string. When the swing arm 11 and the swing arm 2 12 move under the drive of the oil cylinder 14, the conveying hand 13 can accurately grasp and hold the pipe string to ensure that the pipe string will not fall off or slip during the conveying process.

[0039] The feeding mechanism 2 includes an up-and-down moving mechanism 21 and a front-and-back moving mechanism 22 . The front-and-back moving mechanism 22 is arranged on the up-and-down moving mechanism 21 . The pipe column bracket 222 on the front-and-back moving mechanism 22 transports the pipe column to the site.

[0040] The up-and-down moving mechanism 21 includes a lifting cylinder 211 and a lifting chain 212. The lifting cylinder 211 is fixed on the bracket, and the cylinder rod 2262 of the lifting cylinder 211 is connected to the connecting frame 214 of the movable pulley block 1; one end of the lifting chain 212 is fixed on the bracket, and the other end is fixed to the bracket 221 of the front-and-back moving mechanism. Specifically, the lifting chain 212 is connected to the bracket lifting chain connection 2211. The lifting chain 212 bypasses the movable pulley block 1 213, and the cylinder rod 2262 is lifted and lowered to drive the movable pulley block 1 213 to lift and lower, thereby driving the bracket 221 of the front-and-back moving mechanism to lift and lower.

[0041] The lifting cylinder 211 provides power, and through the combination of the movable pulley block 213 and the lifting chain 212, the lifting cylinder 211 lifts the movable pulley block 213, and the movable pulley block 213 pulls up the lifting chain 212, thereby realizing the lifting and lowering movement of the front-rear moving mechanism 22 and the pipe column bracket 222 thereon. In this way, the pipe column bracket 222 can accurately reach the position of the pipe column to receive and transport the pipe column. Figure 2 As shown, the movable pulley block 1 213 is lifted to the highest point, wherein part of the lifting chain 212 is omitted.

[0042] The forward and backward moving mechanism 22 includes a forward and backward moving fixed frame 223, a pipe column bracket 222, a fixed pulley block 224, a movable pulley block 225, a forward and backward moving cylinder 226 and a forward and backward moving wire 227; the front and rear parts of the forward and backward moving fixed frame 223 are provided with a fixed pulley block 224, the movable pulley block 225 is provided on the cylinder rod 2262 of the forward and backward moving cylinder 226, the cylinder barrel 2261 is fixed in the forward and backward moving fixed frame 223, and the movable pulley block 225 moves between the fixed pulley blocks 224; the pipe column bracket 222 is fixed on the forward and backward moving wire 227, and the forward and backward moving wire 227 passes around the fixed pulley block 224 and the movable pulley block 225; the two ends of the forward and backward moving wire 227 are respectively fixed on the forward and backward moving fixed frame 223 and the tensioning mechanism. The tensioning mechanism is a basket screw 228, which is used to tension the wire.

[0043] Driven by the forward and backward moving cylinder 226, the movable pulley block moves between the fixed pulley block 224, driving the forward and backward moving wire 227 and the pipe column bracket 222 to move forward and backward. The pipe column bracket 222 can move forward and backward along the forward and backward moving fixed frame 223 to accurately transport the pipe column to the front end of the track.

[0044] The movable pulley group 225 includes a front wheel and a rear wheel, which are respectively passed around by two ends of the front and rear moving wire 227.

[0045] The front fixed pulley block 224 and the rear fixed pulley block 224 are respectively provided with two upper and lower pulleys, and the two pulleys are used to support the steel wire to move on the pulleys and change the direction of the steel wire.

[0046] The cylinder rod 2262 of the cylinder drives the movable pulley block 225 to move forward and backward, thereby driving the steel wire to move, and the steel wire drives the pipe column bracket 222 to move forward and backward.
