[0040] Such as Figures 1 to 6As shown in the figure, a pipe and rod discharge box includes a pipe box body 1. Inside the pipe box body 1, there are two lifting and carrying rods 2 that are slidably connected in the vertical direction. At both ends of each lifting and carrying rod 2, there is a transmission-connected lifting drive member, and each lifting drive member is arranged on the pipe box body 1. At both ends of the pipe box body 1, there are cross arm retracting and extending devices. At the top of one side of the pipe box body 1, at least two intermediate supports are hinged. At the bottom of each intermediate support, a first hydraulic cylinder 3 is hinged, and the free end of each first hydraulic cylinder 3 is hinged on the pipe box body 1. On the mutually remote sides of the two intermediate supports, there are length measuring devices, and each length measuring device is fixed on the pipe box body 1. On the inner side wall of the pipe box body 1, there is a card slot 22 for limiting the two ends of the cross arm in the height direction, and the cross arm can move up and down in the card slot 22.

[0041] Among them, the card slot 22 is a U-shaped card slot. As Figure 1 shown, on the inner side wall of the pipe box body 1 along the length direction, there are four edge-retaining square pipes. The enclosure formed by every two edge-retaining square pipes and one inner side wall of the pipe box body 1 is a U-shaped card slot.

[0042] As Figure 1 and Figure 2 shown, the lifting drive member includes: a second hydraulic cylinder 4, one end of which is hinged at a place near the bottom of the pipe box body 1, and the other end is hinged with a steel wire rope 5. The free end of the steel wire rope 5 is fixedly connected to one end of the lifting and carrying rod 2; a pulley 6 is rotatably connected and arranged on one side of the pipe box body 1, and the steel wire rope 5 is sleeved on the pulley 6. By driving the steel wire rope 5 to move through the second hydraulic cylinder 4, the steel wire rope 5 drives the lifting and carrying rod 2 to move up and down. There are a total of four groups of lifting drive members. Each second hydraulic cylinder 4 can act independently to level the lifting and carrying rod 2. The two second hydraulic cylinders 4 on the same side can also act simultaneously to tilt the lifting and carrying rod 2. When the four second hydraulic cylinders 4 act simultaneously, the horizontal lifting of the two lifting and carrying rods 2 is realized.

[0043] As Figure 1 、 Figure 4 and Figure 6As shown in the figure, the cross-arm retracting and extending device includes: a U-shaped swing rod 7 sleeved on the top of one end of the pipe box body 1, and first gears 8 are fixedly arranged on the inner sides of both ends of the U-shaped swing rod 7; two second gears 9 are respectively rotatably connected to one side of the pipe box body 1, and the second gears 9 are meshed with the adjacent first gears 8. A connecting block 10 is fixedly arranged on the side of one of the second gears 9 away from the pipe box body 1, and a driving mechanism 11 is hinged at one end of the connecting block 10 away from the second gear 9. The driving mechanism 11 is one of a hydraulic cylinder, a hydraulic motor and an electric push rod, and the free end of the driving mechanism 11 is hinged on the pipe box body 1; two electromagnets 12 are both fixedly arranged on the U-shaped swing rod 7. By pushing the connecting block 10 to move through the driving mechanism 11, the connecting block 10 drives the second gear 9 to rotate, the second gear 9 drives the first gear 8 to rotate, and the first gear 8 drives the U-shaped swing rod 7 to turn over. By arranging the electromagnets 12 on the U-shaped swing rod 7, the electromagnets 12 are energized to adsorb and fix the cross-arms placed at both ends of the pipe box body 1. After the cross-arms are turned over by 180° on the U-shaped swing rod 7, they are placed on the top of a group of pipe columns. At this time, both ends of the cross-arms are respectively located between two clamping grooves 22 for limiting, so that the cross-arms can only move within a small range, and the movement within this range is within the adsorption range of the electromagnets 12. Then the electromagnets 12 are powered off, and the driving mechanism 11 resets, thus completing the placement of the cross-arms on a group of pipe columns. Repeating the above actions to complete the placement of the pipe columns on the entire pipe box body 1. When the pipe columns are taken out, the cross-arms also need to be taken out. The above structure can also be used to take out the cross-arms on each group of pipe columns.

[0044] As Figure 1 shown, at least two turning arms 13 are hinged on the side of the pipe box body 1 away from the intermediate support. When the turning arms 13 are laid flat, they can be used as a pipe column support bridge between the pipe box bodies 1. When the turning arms are swung upwards, they can transfer the pipe columns in one direction.

[0045] As Figure 1 and Figure 3 shown, the intermediate support includes: a V-shaped frame 14, one end of which is hinged on the pipe box body 1, and one place at the bottom of the V-shaped frame 14 is hinged to one end of the first hydraulic cylinder 3; a nylon damping plate 15 is fixedly arranged at one place of the V-shaped frame 14 away from the first hydraulic cylinder 3; two nylon rollers 16 are symmetrically and rotatably connected in the V-shaped groove of the V-shaped frame 14, and the rotation directions of both nylon rollers 16 are along the length direction of the pipe box body 1. There are two groups of nylon rollers 16 built in the intermediate support. The nylon rollers 16 are arranged in a V shape, which can support and position the pipe columns, and can also turn the pipe columns conveyed by the conveying frame into the pipe box body 1. After the pipe columns are placed on the intermediate support, the pipe column length measuring devices at both ends of the pipe columns can operate to level the pipe columns and measure their lengths.

[0046] As Figure 1 and Figure 5As shown in the figure, the length measuring device includes: a length measuring guide rail 17, on one side of which two fixed seats 18 are fixedly provided, and each of the fixed seats 18 is fixedly connected to one side of the pipe box body 1; a ball screw 19, which is rotatably connected inside the length measuring guide rail 17; a servo motor 20, fixedly provided at one end of the length measuring guide rail 17, and the output shaft of the servo motor 20 passes through the length measuring guide rail 17 and is fixedly connected to one end of the ball screw 19; a moving seat 21, sleeved on the ball screw 19 and threadedly connected, and the moving seat 21 is slidably connected to the length measuring guide rail 17. When the pipe string is placed on two intermediate supports, the positions of the two ends of the pipe string from the length measuring assembly are different. By driving the ball screw 19 to rotate through the servo motor 20, the ball screw 19 drives the moving seat 21 to move, and the two moving seats 21 move closer to each other. One of the moving seats 21 will push one end of the pipe string to move until the two moving seats 21 clamp the pipe string to complete the end-aligning work of the pipe string. The servo motor 20 is equipped with a magnetostrictive displacement sensor to measure the length of the pipe string within a set range. A sensor is provided on the moving seat 21, and the start and stop of the servo motor 20 are controlled through the sensor to achieve precise length measurement.

[0047] As Figure 1 shown, the pipe box body 1 is a truss structure as a whole, and the bottom of the pipe box body 1 is a cofferdam structure. During the operation, all sewage and oil stains are recovered inside the cofferdam.

[0048] Two moving baffles 23 are provided inside the pipe box body 1. On the sides of the two moving baffles 23 away from each other, driving screws 24 are rotatably connected. The free ends of each of the driving screws 24 are threadedly connected to one end of the pipe box body 1 respectively. Four guide columns 25 are respectively passed through the two ends of the pipe box body 1, and every four of the guide columns 25 are fixedly connected to the moving baffle 23 respectively. A pressing cover 26 is hinged to the top of each of the moving baffles 23. The moving baffle 23 is used to prevent the pipe string from moving back and forth. By rotating the driving screw 24, the movement of the moving baffle 23 can be realized. The pressing cover 26 on the top of the moving baffle 23 can be folded 180°. After the moving baffle 23 abuts against the pipe end, the pressing cover 26 is folded to fix the pipe end and prevent the pipe string from warping.

[0049] As Figure 1 shown, both ends of the lifting and bearing rod 2 are located in two corresponding card slots 22 on the inner side wall of the pipe box body 1, and the lifting and bearing rod 2 can move up and down along the card slots. The lifting and bearing rod 2 can also be provided with a separate lifting guide rail for lifting movement. However, sharing the card slots with the cross arm for the lifting movement of the lifting and bearing rod 2 can relatively simplify the internal structure setting of the pipe and rod discharge box.

[0050] Working principle: Before working, the lifting driving member drives the lifting load-bearing rod 2 to move up to the topmost position. Then, after placing the pipe string on the intermediate support member, the length measuring devices at both ends of the pipe string can perform the operations of aligning the ends of the pipe string and measuring its length. After the length measurement is completed, the first hydraulic cylinder 3 drives the intermediate support member to swing and tilt, so that the pipe string rolls into the pipe box body 1 under the action of gravity and lands on the two lifting load-bearing rods 2. The lifting load-bearing rods 2 in the pipe box body 1 can be tilted at a certain angle under the action of the lifting driving members on both sides of the pipe box body 1, so that the pipe string rolls from one side of the pipe box body 1 to the other side. When the pipe string rolls in the pipe box body 1, there will be a phenomenon of collision between the pipe strings. In order to reduce the collision intensity between the pipe strings, it is necessary to adjust the telescopic speed of the first hydraulic cylinder 3 through the hydraulic flow regulating valve to control the swinging speed of the intermediate support member, so that the pipe string rolls at an appropriate speed to generate less collision. When a layer is filled on the lifting load-bearing rod 2, it is a group of pipe strings. After the cross arm retracting and extending device rotates 180°, the cross arm is placed on the top of a group of pipe strings to be used for spacing the placement of each group of pipe strings. At the same time, both ends of the cross arm are respectively located between the two card slots 22, so that the cross arm can only move in a small range. After each of the above operation steps is completed, the lifting driving member will drive the lifting load-bearing rod 2 to move down a certain distance, and continue to start the automatic pipe arranging work for another layer of pipe strings. When transporting the pipe string out of the pipe box body 1, the existing operation remote control raises the lifting load-bearing rod 2. After the pipe string is higher than the top surface of the pipe box body 1, the operation remote control raises one side of the lifting load-bearing rod 2 to make it tilt at a certain angle, so that the pipe string rolls out of the pipe box body 1.
