Description

Technical Field

[0001] This invention relates to the field of palletizing technology, and in particular to a CPVC power pipe anti-collapse palletizing device. Background Technology

[0002] In the prior art, CPVC power pipes are commonly used as cable protection pipes. This product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, and good insulation performance. After molding, CPVC power pipes need to be stored. During storage, CPVC power pipes need to be stacked to facilitate subsequent transportation and movement. When stacking CPVC power pipes, it is necessary to ensure the safety of the stacking to avoid damage caused by accidental collapse. Based on this, this application proposes a CPVC power pipe anti-collapse stacking device.

[0003] A search revealed a Chinese patent application with patent number 201922415119.6, which discloses a steel pipe stacking anti-collapse device, consisting of a top rod and a base. The top rod is distributed vertically on the base, with one end fixed to the base and the other end retractable.

[0004] The steel pipe stacking anti-collapse device in the above patent has the following shortcomings: When stacking pipes, since the pipes themselves have a certain length, it is not convenient to adjust the position of the pipes in the lateral direction during the stacking process. As a result, the pipes are prone to instability in the center of gravity when the top rod clamps the pipes, and the stability of the clamping cannot be guaranteed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a CPVC power pipe anti-collapse stacking device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A CPVC power pipe anti-collapse stacking device includes a base, a lifting plate, and a conveying unit, wherein the conveying unit includes:

[0008] U-shaped frame two: It is fixed to the top outer wall of the lifting platform;

[0009] Linkage rod: It is fixed to the inner wall of U-shaped frame 2, and the end of the link rod away from U-shaped frame 2 is fixed to U-shaped frame 1;

[0010] Rotating rod: It is movably connected to the inner wall of the through hole opened on the surface of the U-shaped frame, and the outer wall of the rotating rod is fixed with a first actuating plate and a second actuating plate by pins respectively;

[0011] Connecting rod 2: It is fixed to the outer wall of one side of the U-shaped frame 2, and a guide plate 2 is welded to one end of the connecting rod 2;

[0012] Bending rod: It is movably connected to the inner wall of the through hole opened on the second surface of the guide plate. One end of the bending rod is provided with a clamping assembly, and the second surface of the actuating plate is provided with a waist-shaped hole that matches the outer diameter of the bending rod.

[0013] Connecting rod one: It is fixed to the outer wall of the other side of the U-shaped frame two, and a guide plate one is welded to one end of the connecting rod one;

[0014] The movable frame is movably connected to the inner wall of the through hole on one surface of the guide plate, and the actuating plate has a waist-shaped hole on one surface that matches the outer diameter of the movable frame. A rolling component is provided at one end of the movable frame.

[0015] Preferably, the clamping assembly includes a spring and a pad, the pad being fixed to one end of the bent rod by a pin, and the pad being welded to the outer wall of one side of the pad.

[0016] Preferably, the rolling assembly includes a roller and a guide frame, the guide frame is fixed to one end of the movable frame by a pin, and the roller is movably connected to the inner wall of the guide frame.

[0017] Preferably, a guide rod is fixed to the top outer wall of the base, a horizontal plate is fixed to the top outer wall of the guide rod by a pin, and the same threaded rod is movably connected between the bottom outer wall of the horizontal plate and the top outer wall of the base. A drive motor is fixed to the top outer wall of the horizontal plate, and the output end of the drive motor is connected to the top of the threaded rod through a coupling.

[0018] Preferably, the lifting plate is movably connected to the outer circumference of the guide rod, and a nut adapted to the threaded rod is embedded on the surface of the lifting plate.

[0019] Preferably, a mounting ring is fixed to one side of the outer wall of the connecting rod, and a coil spring is sleeved on the outer circumference of the rotating rod, with both ends of the coil spring fixed to the outer circumference of the rotating rod and the inner surface of the mounting ring respectively by pins.

[0020] Preferably, a bracket is fixed to the top outer wall of the lifting plate, a threaded column is movably connected to the inner wall of the threaded hole on the surface of the bracket, and a rectangular plate is movably connected to the bottom of the threaded column. Spring pieces are welded to the outer walls on both sides of the rectangular plate, and a limit cylinder is fixed to the top inner wall of the bracket.

[0021] Based on the aforementioned solution: a vertical rod is fixed to the top outer wall of the base, and a placement plate is welded to the top outer wall of the vertical rod.

[0022] Based on the aforementioned scheme, the preferred embodiment is as follows: a vertical plate is fixed to the top outer wall of the base, and the same limiting rod is fixed between the two vertical plates by a pin. A side plate is movably connected to the outer circumference of the limiting rod, and a bidirectional lead screw is movably connected between the two vertical plates. Furthermore, a nut that matches the outer diameter of the bidirectional lead screw is embedded on the surface of both side plates.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. By alternating the positions of the clamping component and the rolling component, the rolling component can move the CPVC power pipe to the fixed position by rolling, thereby reducing the wear of the CPVC power pipe. When the CPVC power pipe is moved to the fixed position, the clamping component can clamp the surface of the CPVC power pipe, thereby ensuring the stability of the CPVC power pipe.

[0025] 2. By setting up a drive motor to drive the threaded rod to rotate, the lifting plate can be adjusted in height along the vertical direction under the guidance of the guide rod, so that the clamped and fixed CPVC power pipes can be transported to different heights for stacking.

[0026] 3. By setting up the second spring, the clamping component can clamp the CPVC power pipe from multiple directions, further improving the stability of the CPVC power pipe clamping. At the same time, the downward pressure of the second spring can cause the coil spring to generate elastic deformation. When it is necessary to clamp and fix the CPVC power pipe, the elastic deformation of the coil spring can be used to realize the reverse movement between the clamping component and the rolling component, which can improve the clamping speed of the CPVC power pipe.

[0027] 4. By setting limit rods and bidirectional screws, the spacing between the two side plates can be adjusted, allowing the two side plates to adaptably wrap CPVC power pipes of different diameters, thereby preventing the CPVC power pipes from collapsing after stacking and ensuring the stability of the CPVC power pipe stacking.

Therefore, they should not be construed as limitations on this patent.

[0039] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0040] Example 1:

[0041] A CPVC power pipe anti-collapse stacking device, such as Figures 1-6 As shown, it includes a base 1, a lifting plate 5, and a conveying unit, wherein the conveying unit includes:

[0042] U-shaped frame 214: It is fixed to the top outer wall of the lifting plate 5 by bolts;

[0043] Link 12: It is fixed to the inner wall of U-shaped frame 14 by bolts, and the end of link 12 away from U-shaped frame 14 is fixed to U-shaped frame 9 by bolts;

[0044] Rotating rod 18: It is rotatably connected to the inner wall of the through hole opened on the surface of U-shaped frame 9, and the outer wall of the circumference of rotating rod 18 is fixed with actuating plate 19 and actuating plate 22 respectively by pins.

[0045] Connecting rod 2 17: It is fixed to the outer wall of one side of the U-shaped frame 2 14 by bolts, and a guide plate 2 35 is welded to one end of the connecting rod 2 17;

[0046] Bending rod 23: It is slidably connected to the inner wall of the through hole opened on the surface of the guide plate 2 35. One end of the bending rod 23 is provided with a clamping component, and the surface of the actuating plate 22 is provided with a waist-shaped hole that matches the outer diameter of the bending rod 23.

[0047] Connecting rod 13: It is fixed to the outer wall of the other side of the U-shaped frame 14 by bolts, and a guide plate 15 is welded to one end of the connecting rod 13;

[0048] The movable frame 16 is slidably connected to the inner wall of the through hole on the surface of the guide plate 15, and the surface of the actuating plate 19 is provided with a waist-shaped hole that matches the outer diameter of the movable frame 16. A rolling component is provided at one end of the movable frame 16.

[0049] Preferably, in this embodiment, there are two conveying units. These two units can transport CPVC power pipes that need to be stacked. By setting the conveying units in a "V" shape, the CPVC power pipes can be supported. A rotating rod 18 is provided so that it can simultaneously drive the first actuating plate 19 and the second actuating plate 22 to rotate during rotation. A waist-shaped hole 1 converts the circular motion of the second actuating plate 22 into the linear motion of the bent rod 23 along the second guide plate 35. Similarly, a waist-shaped hole 2 converts the circular motion of the first actuating plate 19 into the linear motion of the moving frame 16 along the first guide plate 15. The linear motion, with the moving frame 16 and the bent rod 23 moving in opposite directions, allows the CPVC power pipe to be conveyed in a rolling manner by adjusting the positions of the rolling assembly and the clamping assembly when it is necessary to transport the CPVC power pipe. This reduces wear on the CPVC power pipe. When it is necessary to fix the CPVC power pipe, the height of the clamping assembly is adjusted to be higher than that of the rolling assembly, allowing the clamping assembly to provide sufficient friction after contacting the surface of the CPVC power pipe, thus ensuring the stability of the CPVC power pipe.

[0050] Furthermore, the clamping assembly includes a spring piece 10 and a pad 11. The pad 11 is fixed to one end of the bent rod 23 by a pin, and the pad 11 is welded to the outer wall of one side of the pad 11.

[0051] The spring sheet 10 is preferably made of spring steel. Spring steel has good toughness and elasticity, which allows the spring sheet 10 to fit tightly against the surface of CPVC power pipes of different outer diameters when it is necessary to clamp and fix the CPVC power pipe, thereby ensuring the stability of the CPVC power pipe during clamping and fixing.

[0052] Furthermore, the rolling assembly includes a roller 20 and a guide frame 21. The guide frame 21 is fixed to one end of the movable frame 16 by a pin, and the roller 20 is rotatably connected to the inner wall of the guide frame 21.

[0053] By incorporating rollers 20, the CPVC power pipe can be conveyed by rolling, thereby reducing damage to the surface of the CPVC power pipe.

[0054] Furthermore, a guide rod 4 is fixed to the top outer wall of the base 1 by bolts, a horizontal plate 3 is fixed to the top outer wall of the guide rod 4 by pins, and the same threaded rod 8 is rotatably connected between the bottom outer wall of the horizontal plate 3 and the top outer wall of the base 1. A drive motor 7 is fixed to the top outer wall of the horizontal plate 3 by bolts, and the output end of the drive motor 7 is connected to the top of the threaded rod 8 through a coupling. The lifting plate 5 is slidably connected to the circumferential outer wall of the guide rod 4, and a nut that matches the threaded rod 8 is embedded on the surface of the lifting plate 5.

[0055] The drive motor 7 drives the threaded rod 8 to rotate, allowing the lifting plate 5 to move vertically under the guidance of the guide rod 4. This allows the height of the conveying section to be adjusted within a certain range, enabling the CPVC power pipes to be stacked when they need to be stacked, thus ensuring safety and improving efficiency during stacking.

[0056] Furthermore, an mounting ring 25 is fixed to one side of the outer wall of the connecting rod 12 by bolts, and a coil spring 24 is sleeved on the outer circumference of the rotating rod 18, with the two ends of the coil spring 24 respectively fixed to the outer circumference of the rotating rod 18 and the inner surface of the mounting ring 25 by pins.

[0057] Because the coil spring 24 has a certain elasticity in the circumferential direction, when no external force is involved, the initial position of the clamping component and the rolling component can be limited by the coil spring 24, thereby ensuring that the height of the rolling component is higher than that of the clamping component in the initial stage. This allows the CPVC power pipe to be moved to a fixed position by the rolling component during the transfer, and then clamped and fixed by the clamping component. After the CPVC power pipe is clamped and fixed, it is stacked by lifting it.

[0058] Furthermore, a bracket 6 is fixed to the top outer wall of the lifting plate 5 by bolts. A threaded column 26 is rotatably connected to the inner wall of the threaded hole on the surface of the bracket 6, and a rectangular plate 29 is rotatably connected to the bottom of the threaded column 26. Spring pieces 28 are welded to the outer walls on both sides of the rectangular plate 29. A limit cylinder 27 is fixed to the top inner wall of the bracket 6 by bolts, and the inner diameter of the limit cylinder 27 and the outer diameter of the rectangular plate 29 are mutually compatible.

[0059] By rotating the threaded column 26, the rectangular plate 29 can move up and down in the vertical direction under the guidance and limiting action of the limiting cylinder 27, thereby adjusting the height of the second spring 28 in the vertical direction. When it is necessary to clamp and fix the CPVC power pipe, the second spring 28 can be used in conjunction with the first spring 10 to improve the stability and safety of clamping and fixing the CPVC power pipe.

[0060] Meanwhile, when the second spring 28 presses against the top of the CPVC power pipe during its downward movement, it will exert a downward pressure on the top of the CPVC power pipe. At this time, the coil spring 24 will undergo elastic deformation under the action of the downward pressure generated by the second spring 28, causing the rotating rod 18 to rotate at a certain angle relative to the connecting rod 12. During this process, the clamping assembly and the rolling assembly move in opposite directions. That is, after the rolling assembly moves the CPVC power pipe to a fixed position, the clamping assembly gradually moves to contact the surface of the CPVC power pipe, thereby realizing the automatic clamping and fixing of the CPVC power pipe.

[0061] In this embodiment, when CPVC power pipes need to be stacked, the drive motor 7 first drives the threaded rod 8 to rotate, causing the lifting plate 5 to move to its lowest position under the guidance of the guide rod 4. Then, the CPVC power pipes to be stacked are moved to the conveying section manually or by machine. Initially, the height of the rolling assembly is higher than the height of the clamping assembly. After placing the CPVC power pipe on the surface of the rolling assembly, the CPVC power pipe is pushed laterally, causing it to move to the two conveying sections by rolling. Then, the threaded column 26 is rotated, causing the spring piece 28 to move vertically downwards under the guidance and limiting action of the limiting cylinder 27. As the spring piece 28 moves downwards... A downward pressure is gradually applied to the top of the CPVC power pipe. During this process, the coil spring 24 gradually undergoes elastic deformation under the pressure, causing the clamping component and the rolling component to move in opposite directions. When the clamping component moves to contact the surface of the CPVC power pipe, the spring plate 28 can clamp and fix the CPVC power pipe. Then, the height of the CPVC power pipe is adjusted so that after the CPVC power pipe moves to the stacking position, the threaded column 26 is rotated in the opposite direction so that the spring plate 28 disengages from the top of the CPVC power pipe again. The rebound force of the coil spring 24 makes the rolling component and the clamping component quickly reset. Then, the CPVC power pipe is moved to the stacking position by the rolling component to complete the stacking.

[0062] Example 2:

[0063] A CPVC power pipe anti-collapse stacking device, such as Figure 7 As shown, in order to facilitate the stacking and palletizing of CPVC power pipes, this embodiment makes the following additions based on embodiment 1: a vertical rod 31 is fixed to the top outer wall of the base 1 by bolts, a placement plate 30 is welded to the top outer wall of the vertical rod 31, a vertical plate 32 is fixed to the top outer wall of the base 1 by bolts, a limiting rod 33 is fixed between the two vertical plates 32 by pins, a side plate 2 is slidably connected to the outer circumference of the limiting rod 33, a bidirectional screw 34 is rotatably connected between the two vertical plates 32, and a nut that matches the outer diameter of the bidirectional screw 34 is embedded on the surface of both side plates 2;

[0064] The CPVC power pipe can be supported by the placement plate 30. By rotating the bidirectional screw 34, the two side plates 2 can be moved in opposite directions under the guidance of the limit rod 33, thereby adjusting the interval between the two side plates 2 so that CPVC power pipes of different diameters can be stacked.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
