Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe conveying equipment, and specifically to a paint spraying steel pipe conveying device. Background Technology

[0002] In the field of steel pipe processing and surface treatment, painting is a crucial step in improving the corrosion resistance and appearance of steel pipes. Painted steel pipes need to be transported using specialized conveying equipment for subsequent storage or assembly.

[0003] Traditional methods for transporting painted steel pipes primarily utilize trolleys, forklifts, or simple shelving. The operation typically involves directly stacking the pipes and placing them directly onto the trolley or shelving. Since the length of the steel pipes is generally less than the effective load-bearing length of the transport equipment (e.g., the trolley's length), the axial length of the pipes in the stacked state is much smaller than the trolley's length, resulting in significant gaps between the pipes and between the pipes and the trolley. When the trolley moves or turns, the pipes are prone to relative sliding, swaying, or tilting due to inertia, leading to frequent collisions and friction between the pipes and between the pipes and the trolley, scratching or peeling the paint. Furthermore, transport devices often lack buffer or isolation structures designed specifically for the needs of painted steel pipes, failing to effectively absorb transport vibrations or impact energy, resulting in localized damage or even large-area paint peeling. This not only affects the appearance quality of the steel pipes and reduces product added value but may also damage the integrity of the anti-corrosion coating, weakening its corrosion resistance and shortening its service life. Therefore, we propose a painted steel pipe conveying device to solve these problems. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides a painting steel pipe conveying device, mainly to solve the problem in existing technologies where the length of the steel pipes is generally less than the effective load-bearing length of the transport equipment (e.g., the length of the trolley body). When the steel pipes are stacked, their axial length is much smaller than the length of the trolley body, resulting in large gaps between the steel pipes and between the steel pipes and the trolley body during transport. When the trolley moves or turns, the steel pipes are prone to relative sliding, swaying, or tilting due to inertia, leading to frequent collisions and friction between the pipes and between the pipes and the trolley body, causing scratches or peeling of the paint. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-3 Please provide a detailed explanation:

[0024] A paint spraying steel pipe conveying device, comprising:

[0025] Mounting slot 1, mounting plate 2 is fixed on one side of mounting slot 1, rectangular notches 101 are constructed on the two sides of mounting slot 1 away from mounting plate 2, and self-locking casters 3 are installed at the four corners of the bottom surface of mounting slot 1.

[0026] Support blocks 4 are fixed at intervals between the inner walls of the mounting groove 1. The top of the support blocks 4 is constructed with arc-shaped grooves 401 at equal intervals, and the painted steel pipes are embedded in the arc-shaped grooves 401.

[0027] The limiting rod 5 is detachably set above the two support blocks 4. The limiting rod 5 is set parallel to the support blocks 4. The limiting rod 5 is used to prevent the painted steel pipe from falling out of the arc groove 401.

[0028] A clamping mechanism 6 is disposed between two rectangular notches 101. The clamping mechanism 6 is used to clamp and fix the painted steel pipe. The clamping mechanism 6 includes a guide rod 601 fixed between the inner side walls of the rectangular notches 101. A clamping plate 602 is slidably sleeved on the surface of the guide rod 601. A spring 603 is sleeved on the side of the guide rod 601 away from the mounting plate 2. A lifting rod 604 is rotatably connected to the middle of the side of the clamping plate 602 away from the mounting plate 2 through a bearing.

[0029] Workflow Description:

[0030] When transporting painted steel pipes, workers can first pull the lifting rod 604 outward to compress the spring 603, causing the clamping plate 602 to move away from the mounting plate 2 along the guide rod 601. The painted steel pipes are then inserted one by one into the arc-shaped groove 401 of the support block 4 along the length of the mounting groove 1. After releasing the hand, the spring 603 releases its pressure, and the clamping plate 602 slides along the guide rod 601 toward the painted steel pipe until the steel pipe is clamped between the mounting plate 2 and the clamping plate 602. Next, the limiting rod 5 is installed to prevent the painted steel pipe from detaching from the arc-shaped groove 401. Then, the entire device is moved by pushing it. After the self-locking universal wheel 3 is unlocked, it can turn flexibly. After reaching the target position, the roller is locked to ensure static stability. Then, the clamping mechanism 6 is released, and the lifting rod 604 can be pulled outward again to overcome the force of the spring 603, causing the clamping plate 602 to release the painted steel pipe. The limiting rod 5 is removed, and the steel pipe is taken out along the arc-shaped groove 401, completing the transfer.

[0031] This paint-coated steel pipe conveying device achieves layered isolation of steel pipes through the arc-shaped groove 401 of the support block 4, avoiding stacking collisions. The clamping mechanism 6 automatically adapts to the size of the steel pipe using the pressure of the spring 603, providing a dynamically stable clamping force. The limit rod 5 and the clamping mechanism 6 together restrict the axial and radial displacement of the steel pipe, ensuring no shaking or tilting during transportation and guaranteeing the quality of the anti-corrosion coating of the paint-coated steel pipe. It solves the problem of collision and wear caused by mismatched steel pipe lengths in traditional transportation tools, realizing efficient and damage-free transfer of paint-coated steel pipes, and combining convenient operation with reliable protection.

[0032] like Figure 3 As shown, in some embodiments, the side of the mounting groove 1 away from the mounting plate 2 is provided with a strip hole 102. The end of the lifting rod 604 away from the clamping plate 602 slides through the strip hole 102, and a strip plate 605 that can pass through the strip hole 102 is fixed in the middle. More specifically, when the lifting rod 604 is pulled outward so that the strip plate 605 passes through the strip hole 102, and then the lifting rod 604 is rotated so that the strip plate 605 is misaligned with the strip hole 102 and released, the spring 603 can be kept in a compressed state, and it is convenient for workers to place the paint spraying steel pipe.

[0033] like Figure 1 As shown, in some embodiments, positioning posts 7 are fixed at equal intervals on the inner side of the mounting plate 2. The positioning posts 7 are conical, and their center lines pass through the center of the arc groove 401. More specifically, the positioning posts 7 adopt a conical design. This design enables the steel pipe to automatically center when embedded in the arc groove 401, avoiding deviation or tilting, thereby eliminating the risk of collision caused by misalignment. This design achieves precise positioning and stable fixation of the painted steel pipe by setting conical positioning posts 7 at equal intervals on the inner side of the mounting plate 2 and aligning their center lines with the center of the arc groove 401.

[0034] like Figure 1As shown, in some embodiments, a zigzag notch 103 is constructed above the side wall of the mounting groove 1. The two ends of the limiting rod 5 are slidably embedded in the zigzag notch 103. More specifically, the two ends of the limiting rod 5 are respectively embedded in the two ends of the zigzag notch 103. The notch is zigzag-shaped to provide the limiting rod 5 with a zigzag sliding track. When the limiting rod 5 slides to the target position, its lower surface is in close contact with the outer wall of the steel pipe to form a block, preventing the steel pipe from falling out of the arc groove 401 during transportation.

[0035] like Figure 1 As shown, in some embodiments, a rubber pad is provided inside the arc-shaped groove 401, and a rubber sleeve is fitted on the surface of the limiting rod 5. More specifically, the shape of the rubber pad is completely consistent with the arc-shaped groove 401, closely fitting the inner wall of the groove to ensure full contact after the steel pipe is embedded. As an elastic intermediate layer between the steel pipe and the metal arc-shaped groove 401, the rubber pad can absorb vibration energy during transportation and reduce rigid collisions between the steel pipe and the groove. When the limiting rod 5 contacts the steel pipe, the rubber sleeve can replace direct metal-to-metal friction, preventing scratches on the paint surface. The elasticity and friction of the rubber sleeve can assist the limiting rod 5 in pressing the steel pipe and suppressing shaking during transportation.

[0036] like Figure 1 As shown, in some embodiments, push rods 8 are fixedly provided at intervals on the upper outer side of the mounting plate 2. More specifically, by setting push rods 8, it is convenient for workers to move the mounting slot 1, thereby improving the portability of operation.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
