[0038] The following is combined Figures 1 to 4 The embodiments of this utility model are described below.

[0039] One type of receiving rack in this embodiment includes:

[0040] The lower frame 101 is provided with a horizontal slide rail 103 along its length.

[0041] The upper frame 102 has a horizontal slider 104 at its bottom, which is slidably connected to the horizontal slide rail 103.

[0042] The avoidance cylinder 201 has its fixed part fixedly connected to the lower frame 101, and its movable part being drivenly connected to the upper frame 102;

[0043] A follow-up receiving mechanism is installed on the upper frame 102, and the follow-up receiving mechanism is used to receive pipe materials.

[0044] In this embodiment, the lower frame 101 serves as the basic support structure, and the horizontal slide rail 103 is arranged along the length of the lower frame 101, providing a precise guide path for the upper frame 102 and ensuring that the upper frame 102 remains stable and without deviation during movement. Multiple horizontal sliders 104 are distributed at the bottom of the upper frame 102, and the horizontal sliders 104 are slidably connected to the horizontal slide rail 103, allowing the upper frame 102 to move along the horizontal slide rail 103. The avoidance cylinder 201 serves as the power source, driving the upper frame 102 to move back and forth along the slide rail. This enables the follow-up receiving mechanism on the upper frame 102 to quickly avoid the pipe cutter chuck, effectively solving the problem in the prior art where the receiving rack is difficult to quickly avoid when cutting tail material, thereby significantly improving the continuity of the cutting operation and production efficiency.

[0045] The avoidance principle is as follows: when the receiving rack does not need to avoid the pipe cutter chuck, the movable part of the avoidance cylinder 201 is in the extended state, causing the upper frame 102 to move along the horizontal slide rail 103 to a position close to the pipe cutter chuck; when the receiving rack needs to avoid, the avoidance cylinder 201 is activated, and its movable part begins to retract, pulling the upper frame 102 along the horizontal slide rail 103 through the connecting plate 204, gradually moving away from the pipe cutter chuck, and the upper frame 102 and its follow-up receiving mechanism quickly leave the working area of ​​the pipe cutter chuck; after the pipe cutter completes the tail material cutting, the avoidance cylinder 201 reverses its action, and its movable part extends again, restoring the upper frame 102 to its initial position;

[0046] Because when the avoidance cylinder 201 retracts, it applies a pulling force to the upper frame 102, the force is more stable, the positioning accuracy is higher, and the avoidance control is more accurate, thus avoiding the upper frame 102 from shaking or shifting due to excessive thrust.

[0047] Specifically, the receiving rack further includes a connecting plate 204, a hydraulic buffer 202, and a limiting baffle 203; the movable part of the avoidance cylinder 201 is connected to the upper frame 102 via the connecting plate 204; the fixed part of the hydraulic buffer 202 is fixedly connected to the lower frame 101, and the movable part of the hydraulic buffer 202 is located on the movement path of the movable part of the avoidance cylinder 201; the limiting baffle 203 is fixedly connected to the lower frame 101 and is located at the end of the movement path of the movable part of the avoidance cylinder 201; when the movable part of the avoidance cylinder 201 moves, the connecting plate 204 first abuts against the movable part of the hydraulic buffer 202 to buffer and decelerate, and then abuts against the limiting baffle 203 to stop the movement.

[0048] In this embodiment, when the device needs to return to its initial position after completing the avoidance action, its movable part extends and pushes the upper frame 102 along the horizontal slide rail 103 via the connecting plate 204. The connecting plate 204 acts as a transmission link between the avoidance cylinder 201 and the upper frame 102, responsible for transmitting the power of the avoidance cylinder 201 to the upper frame 102. When the upper frame 102 approaches the initial position, the connecting plate 204 abuts against the movable part of the hydraulic buffer 202. At this time, the liquid inside the hydraulic buffer 202 is compressed, generating progressive resistance, which gradually reduces the moving speed of the upper frame 102. This resistance gradually increases as the pressure applied by the connecting plate 204 increases, thereby achieving smooth deceleration and avoiding damage to the equipment caused by the impact force due to sudden deceleration. After the connecting plate 204 decelerates, it continues to move along its movement path and finally abuts against the limit baffle 203. The limit baffle 203 precisely limits the final position of the connecting plate 204, ensuring that the upper frame 102 stops accurately at the initial position.

[0049] By setting a hydraulic buffer 202 and a limit baffle 203 on the movement path of the moving part of the avoidance cylinder 201, the overshoot phenomenon caused by the excessive extension of the avoidance cylinder 201 is avoided, and the stability of the equipment is enhanced.

[0050] Specifically, the follow-up receiving mechanism includes a drive assembly, a lifting adjustment assembly, a tilt adjustment assembly, and a flap 601; multiple lifting adjustment assemblies and tilt adjustment assemblies are provided; multiple lifting adjustment assemblies are disposed on the upper frame 102 and distributed along the length direction of the upper frame 102; the lifting adjustment assemblies are drivenly connected to the flap 601; each lifting adjustment assembly is drivenly connected to one tilt adjustment assembly; the tilt adjustment assembly is drivenly connected to the flap 601; the drive assembly is disposed on the upper frame 102, and multiple lifting adjustment assemblies are drivenly connected to each other through the drive assembly.

[0051] In this embodiment, the drive component acts as a power source, starting when the receiving rack is working, and transmitting power to the lifting and adjusting component through the transmission component. Upon receiving the power from the drive component, the lifting and adjusting component begins to operate, raising or lowering the flap 601 to a suitable position. The tilt adjustment component operates based on the lifting and adjusting component, pushing the flap 601 to rotate, thereby changing the angle between the flap 601 and the horizontal plane to adapt to different pipe receiving and conveying requirements. By separately setting the lifting and adjusting components and the tilt adjustment component, the height and angle of the flap 601 can be independently and precisely adjusted. By distributing multiple lifting and tilt adjustment components along the length of the upper frame 102, the support points and adjustment points for the flap 601 are increased, improving the stability of the adjustment process. When adjusting the height and angle of the flap 601, the force can be distributed more evenly, reducing the swaying and deformation of the flap 601 and ensuring the smoothness of the receiving process.

[0052] Specifically, the drive assembly includes a servo motor 301, a drive shaft 302, and a plurality of drive gears 303 distributed along the length of the drive shaft 302; the servo motor 301 is mounted on the upper frame 102; the output end of the servo motor 301 is connected to the drive shaft 302, and the drive shaft 302 is coaxially connected to all the drive gears 303; each drive gear 303 is connected to the corresponding lifting adjustment assembly.

[0053] When the height of the flip plate 601 needs to be adjusted, the servo motor 301 is started. The servo motor 301 acts as a power source, converting electrical energy into mechanical energy and outputting rotational power through its output end. The output end of the servo motor 301 can be connected to the transmission shaft 302 via a coupling. The rotation of the transmission shaft 302 drives the transmission gear 303, which is coaxially connected to it, to rotate. Since the transmission gear 303 meshes with the vertical rack 406, the rotation of the transmission gear 303 will cause the vertical rack 406 to move linearly along the rotation direction of the transmission gear 303, thereby driving the mounting part 401 to move up and down. The mounting part 401 is connected to the flip plate 601 through the first hinge 402, thereby realizing the height adjustment of the flip plate 601.

[0054] The servo motor 301 has stable power output characteristics, which can provide continuous and reliable power support for the lifting and adjusting components. It can also be precisely controlled by the electrical control system, and can easily realize functions such as forward and reverse rotation and speed adjustment. Operators can flexibly adjust the speed and direction of the height adjustment of the flip plate 601 according to the actual material receiving needs.

[0055] Specifically, the lifting adjustment assembly includes a mounting component 401, a first hinge component 402, and a vertical slider 403; the vertical slider 403 is fixedly connected to the upper frame 102, the mounting component 401 is provided with a vertical slide rail 404, and the vertical slider 403 is slidably connected to the vertical slide rail 404; the vertical slider 403 is provided with a first bearing seat 405, and the transmission shaft 302 is installed in the first bearing seat 405; the mounting component 401 is also provided with a vertical rack 406, and the vertical rack 406 meshes with the transmission gear 303; the top end of the mounting component 401 is hinged to the flip plate 601 through the first hinge component 402, and the mounting component 401 is fixedly connected to the tilt adjustment assembly.

[0056] After the drive assembly starts, it transmits power to the drive shaft 302. Since the drive shaft 302 and the drive gear 303 are coaxially connected, the rotation of the drive shaft 302 will drive the drive gear 303 to rotate synchronously. The drive gear 303 meshes with the vertical rack 406. When the drive gear 303 rotates, according to the transmission principle of gear and rack, relative motion will be generated on the vertical rack 406. Since the vertical rack 406 is fixed on the mounting part 401, the rotation of the drive gear 303 will cause the mounting part 401 to perform vertical linear motion relative to the upper frame 102. During the up-and-down movement of the mounting component 401, the sliding engagement between the vertical slider 403 and the vertical slide rail 404 serves as a guide, allowing the vertical slider 403 to slide smoothly along the vertical slide rail 404. This ensures that the mounting component 401 can only move in a straight line in the vertical direction, avoiding swaying and offset during movement, thereby ensuring the stability of the height adjustment of the flip plate 601. The top of the mounting component 401 is hinged to the flip plate 601 through the first hinge 402. The movement of the mounting component 401 is transmitted to the flip plate 601 through the first hinge 402, thereby realizing the height adjustment of the flip plate 601.

[0057] The tilt adjustment component is fixedly connected to the mounting component 401. During height adjustment, the change in position of the mounting component 401 is transmitted to the tilt adjustment component, causing the tilt adjustment component to change height synchronously with the flap 601. This ensures that when the tilt adjustment component adjusts the flap 601, its adjustment action only involves angle changes and not height changes. For example, when the flap 601 is raised or lowered due to the lifting adjustment component, the tilt adjustment component will also rise or fall synchronously. However, its internal adjustment mechanism will only adjust the angle of the flap 601, ensuring that the flap 601 is at a suitable tilt angle at different heights to support the pipe.

[0058] Specifically, the tilt adjustment assembly includes a connector 501, a drive cylinder 502, and a second hinge 503; the connector 501 is fixedly connected to the mounting member 401, the fixed part of the drive cylinder 502 is hinged to the connector 501, and the movable part of the drive cylinder 502 is hinged to the flap 601 through the second hinge 503.

[0059] When the lifting and adjusting component is working, it drives the mounting part 401 to move up and down to adjust the height of the flip plate 601. Since the mounting part 401 is fixedly connected to the connecting part 501, the connecting part 501 will change height synchronously with the mounting part 401, thereby achieving coordination between the angle adjustment process and the height adjustment process. While the height of the flip plate 601 changes, the tilt adjustment component can adjust the angle of the flip plate 601 simultaneously to ensure that the receiving rack can accurately receive the pipe at different heights and angles.

[0060] When the angle of the flap 601 needs to be adjusted, the drive cylinder 502 starts working. If the movable part of the drive cylinder 502 extends, it applies a pushing force to the flap 601 through the second hinge 503, causing the flap 601 to rotate around the hinge point between the first hinge 402 and the mounting part 401, thereby changing the angle of the flap 601. If the movable part of the drive cylinder 502 retracts, it applies a pulling force to the flap 601, causing the flap 601 to rotate in the opposite direction, achieving reverse angle adjustment. By precisely controlling the extension and retraction of the movable part of the drive cylinder 502, the flap 601 can be adjusted to the required tilt angle to adapt to different pipe support requirements.

[0061] Specifically, the flip plate 601 is provided with an installation groove along its width direction, and the two ends of the installation groove are fixed with second bearing seats 802. A roller shaft 801 is rotatably connected between the two second bearing seats 802. The highest point of the outer peripheral surface of the roller shaft 801 is higher than the plate surface of the flip plate 601.

[0062] When the pipe is conveyed onto the flip plate 601 of the receiving rack, the pipe will first come into contact with the roller 801 because the highest point of the outer circumference of the roller 801 is higher than the plate surface of the flip plate 601. Under the action of the pipe's own weight and the subsequent conveying force, the roller 801 will rotate around its axis in the second bearing seat 802. This rotation can reduce the friction between the pipe and the flip plate 601, allowing the pipe to move more smoothly on the plate surface of the flip plate 601, which helps to improve the conveying efficiency of the pipe and reduce the jamming and wear of the pipe during the conveying process.

[0063] Specifically, the receiving rack also includes a material platform 701, which is located on one side of the lower frame 101, and the flip plate 601 is inclined toward one side of the material platform 701.

[0064] When the pipe is conveyed onto the flip plate 601 of the automatic receiving rack, the pipe will automatically slide along the tilted flip plate 601 towards the material platform 701 due to the tilt of the flip plate 601 towards the material platform 701 under its own weight. This realizes the automatic transfer of the pipe from the flip plate 601 to the material platform 701 without the need for additional power equipment to push the pipe to move.

[0065] Specifically, the material platform 701 is provided with a first baffle 702 and a second baffle 703 on both sides in the length direction; the first baffle 702 and the second baffle 703 both extend along the length direction of the material platform 701; the first baffle 702 is vertically arranged on the side away from the lower frame 101; the second baffle 703 is arranged on the side close to the lower frame 101, and its upper end is inclined towards the lower frame 101.

[0066] In this embodiment, the first baffle 702 is vertically disposed on the side away from the lower frame 101 and extends along the length of the material platform 701, covering the entire width of the material platform 701 to ensure that the pipe will not fall from the outside of the material platform 701; the second baffle 703 is disposed on the side close to the lower frame 101, with its upper end inclined toward the lower frame 101, to guide the pipe to slide toward the central area of ​​the material platform 701, avoiding the pipe from accumulating or getting stuck at the edge of the material platform 701; the first baffle 702 and the second baffle 703 together constitute the protective structure of the material platform 701, ensuring the stability and safety of the pipe on the material platform 701 and reducing the risk of the pipe falling off the material platform 701.

[0067] Specifically, the flap 601 is provided with a protective baffle 602 on the side away from the material table 701, and the protective baffle 602 extends along the length of the flap 601.

[0068] Regardless of whether the flap 601 is tilted or horizontal, the protective baffle 602 can prevent the pipe from falling to the side other than the material table 701, ensuring that the pipe can only slide or be moved towards the material table 701.
