Description

Technical Field

[0001] This utility model relates to the field of plastic-coated composite steel pipe processing equipment, and in particular to a suspended plastic-coated composite steel pipe conveyor. Background Technology

[0002] Plastic-coated composite steel pipe, as a type of steel-plastic composite pipe, forms a protective layer by melting polyethylene, epoxy powder and other organic materials on the inner wall of the steel pipe. It combines the high strength and easy connection characteristics of steel pipe with the corrosion resistance and pollution resistance of plastic layer. With a design life of up to 50 years, it is widely used in water supply and drainage, fire protection and other fields. In its processing, the conveying link after plastic coating directly affects the product quality and subsequent performance. Therefore, the rationality requirements of the conveying equipment are extremely high.

[0003] Chinese patent CN203767443U discloses a suspended plastic-coated composite steel pipe conveyor frame with a scientific and reasonable structural design. It has the advantages of beautiful appearance, good connection strength and effective reduction of loss. It is a highly innovative suspended plastic-coated composite steel pipe conveyor frame.

[0004] The aforementioned patent documents lack an automated lifting device. In the process of hanging the plastic-coated composite steel pipe onto the hook of the conveyor frame, it is necessary to rely on manual labor or simple tools to lift both ends of the steel pipe and accurately align them with the hook position. Manual lifting is not only extremely labor-intensive, but if the operation is not done properly, the steel pipe may slip from the hands, posing a safety hazard of injuring the operator or damaging the equipment. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: In the process of hanging plastic-coated composite steel pipes onto the hooks of the conveyor frame, it is necessary to rely on manual labor or simple tools to lift both ends of the steel pipes and accurately align them with the hook positions. Manual lifting is not only extremely labor-intensive, but if the operation is not done properly, the steel pipes may slip from the hands, posing a safety hazard of injuring the operators or damaging the equipment. Therefore, a suspended plastic-coated composite steel pipe conveyor frame is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A suspended plastic-coated composite steel pipe conveyor frame includes an annular slide, on which multiple sliding seats are slidably installed, and a drive assembly for driving the multiple sliding seats to slide is provided on the annular slide. Each of the sliding seats has a bracket fixedly installed at its lower end. A mounting base is provided below the bracket. A bidirectional cylinder is fixedly installed in the middle part of the upper surface of the mounting base. Slider blocks are symmetrically slidably installed on the upper surface of the mounting base through a sliding assembly. The two ends of the bidirectional cylinder are fixedly connected to two sliders respectively. A support rod is rotatably installed on each of the two sliders. The ends of the two support rods away from the sliders are rotatably connected to the lower end of the bracket. The lower surface of the mounting base is provided with a movable groove, and an L-shaped hook is symmetrically slidably installed in the movable groove through a movable component.

[0007] Preferably, the sliding assembly includes two slide rails symmetrically fixedly mounted on the upper surface of the mounting base, and the two sliders are symmetrically slidably mounted on the two slide rails.

[0008] Preferably, the moving component includes two sliding blocks and an adjusting component for driving the two sliding blocks to move relative to each other. The two sliding blocks are symmetrically slidably installed in the moving groove, and the two hooks are respectively fixedly installed on the two sliding blocks.

[0009] Preferably, the adjusting component includes a threaded rod horizontally rotatably mounted in the moving groove and a drive motor fixedly mounted at one end of the mounting base. The threads at the left and right ends of the threaded rod have opposite helical directions. One end of the threaded rod passes through the moving groove and is fixedly connected to the output end of the drive motor. The two sliding blocks are symmetrically threaded onto the threaded rod.

[0010] Preferably, the drive assembly includes two vertically symmetrically rotatably mounted on an annular slide, two sprockets respectively fixedly mounted on the lower ends of the two rotating shafts, a chain meshing with the two sprockets, a servo motor fixedly mounted on the annular slide, and multiple connecting rods fixedly mounted on the chain. One end of each of the multiple connecting rods is fixedly connected to multiple sliding seats. Support plates are symmetrically fixedly mounted on the annular slide, and both rotating shafts are vertically rotatably mounted on the two support plates.

[0011] Preferably, both hooks are fitted with anti-slip pads, which are made of rubber.

[0012] The beneficial effects of this utility model are as follows: 1. Insert one end of each of the two hooks into both ends of the composite steel pipe. By setting up a bidirectional cylinder, slider, support rod and other structures on the mounting base, the bidirectional cylinder drives the slider to slide along the sliding assembly, which in turn drives the support rod to rotate, thereby realizing the automatic lifting and lowering of the mounting base and hooks. This eliminates the need for manual or simple tools to lift the plastic-coated composite steel pipe, greatly reducing the labor intensity of operators, avoiding the possibility of the steel pipe slipping during manual lifting, reducing the safety hazards of injuring operators or damaging equipment, and improving the safety of operation. 2. In the moving component, the drive motor drives the threaded rod to rotate. Since the spiral directions of the threads at the left and right ends of the threaded rod are opposite, the two sliding blocks can drive the hooks to move relative to each other, thereby adjusting the hook spacing. This can adapt to the loading requirements of plastic-coated composite steel pipes of different diameters, enhancing the versatility and practicality of the conveyor frame.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-2 A suspended plastic-coated composite steel pipe conveyor frame includes an annular slide rail 1, on which multiple sliding seats 2 are slidably installed. The annular slide rail 1 is provided with a drive assembly for driving the multiple sliding seats 2 to slide. The annular slide rail 1 provides a sliding track for the sliding seats 2. The drive assembly can drive the sliding seats 2 to move along the annular slide rail 1, thereby realizing the conveying of plastic-coated composite steel pipes.

[0017] Reference Figure 3 A bracket 3 is fixedly installed at the lower end of multiple sliding seats 2. A mounting seat 4 is provided below the bracket 3. A two-way cylinder 5 is fixedly installed in the middle part of the upper surface of the mounting seat 4. A slider 6 is symmetrically slidably installed on the upper surface of the mounting seat 4 through a sliding component. The two ends of the two-way cylinder 5 are fixedly connected to two sliders 6 respectively. A support rod 7 is rotatably installed on each of the two sliders 6. The ends of the two support rods 7 away from the sliders 6 are rotatably connected to the lower end of the bracket 3. A moving groove is opened on the lower surface of the mounting seat 4. An L-shaped hook 8 is symmetrically slidably installed in the moving groove through a moving component.

[0018] The bracket 3 connects the sliding seat 2 and the support rod 7. The mounting base 4 is the basic carrier for mounting the bidirectional cylinder 5, the slider 6, the moving component, and the hook 8. When the bidirectional cylinder 5 is working, the piston rods at both ends will extend or retract, thereby driving the two sliders 6 to slide relative to or towards each other on the sliding component. The sliding of the sliders 6 will cause the support rod 7 to rotate, thereby realizing the lifting and lowering of the mounting base 4, so as to hang or remove the plastic-coated composite steel pipe. The moving component can adjust the distance between the two hooks 8 to accommodate plastic-coated composite steel pipes of different diameters. The hooks 8 are used to hook the plastic-coated composite steel pipe to achieve its hanging.

[0019] Reference Figure 5 The sliding assembly includes two slide rails 9 symmetrically fixedly mounted on the upper surface of the mounting base 4. Two sliders 6 are symmetrically slidably mounted on the two slide rails 9. The slide rails 9 provide guidance and support for the sliding of the sliders 6, ensuring that the sliders 6 can slide stably along a fixed trajectory under the drive of the bidirectional cylinder 5, avoiding the sliders 6 from deviating or shaking during the sliding process, thereby ensuring the stability of the rotation of the support rod 7, and thus ensuring the smoothness of the lifting and lowering of the mounting base 4.

[0020] Reference Figure 4 The moving component includes two sliding blocks 10 and an adjusting component for driving the two sliding blocks 10 to move relative to each other. The two sliding blocks 10 are symmetrically slidably installed in the moving groove. Two hooks 8 are respectively fixedly installed on the two sliding blocks 10. The adjusting component includes a threaded rod 11 that is horizontally rotatably installed in the moving groove and a drive motor 12 that is fixedly installed on one end of the mounting base 4. The threads at the left and right ends of the threaded rod 11 are in opposite directions. One end of the threaded rod 11 passes through the moving groove and is fixedly connected to the output end of the drive motor 12. The two sliding blocks 10 are symmetrically threaded onto the threaded rod 11.

[0021] The moving groove provides space for the sliding block 10 to slide. When the drive motor 12 works, it will drive the threaded rod 11 to rotate. Since the threads at the left and right ends of the threaded rod 11 are in opposite directions, and the two sliding blocks 10 are respectively threaded onto the left and right ends of the threaded rod 11, the rotation of the threaded rod 11 will cause the two sliding blocks 10 to slide relative to each other or towards each other. The sliding of the sliding block 10 will drive the hook 8 fixed on it to move synchronously, thereby realizing the adjustment of the distance between the two hooks 8 to adapt to the hanging requirements of plastic-coated composite steel pipes of different diameters. When suspending the composite steel pipe, the steel pipe is moved between the two hooks 8, and the threaded rod 11 drives the two hooks 8 to move closer to each other. One end of the two hooks 8 is inserted into the two ends of the composite steel pipe respectively.

[0022] Reference Figure 1The drive assembly includes two vertically symmetrically rotating shafts 13 mounted on an annular slide rail 1, two sprockets 14 respectively fixedly mounted on the lower ends of the two rotating shafts 13, chains 15 meshing and sleeved on the two sprockets 14, a servo motor 16 fixedly mounted on the annular slide rail 1, and multiple connecting rods 17 fixedly mounted on the chains 15. One end of the multiple connecting rods 17 is fixedly connected to multiple sliding seats 2 respectively. Support plates 18 are symmetrically fixedly mounted on the annular slide rail 1, and both rotating shafts 13 are vertically rotatably mounted on the two support plates 18.

[0023] The support plate 18 provides mounting and support points for the rotating shaft 13, ensuring that the rotating shaft 13 can rotate stably. When the servo motor 16 is working, it will drive one of the rotating shafts 13 to rotate. This rotating shaft 13 will drive the sprocket 14 fixedly connected to it to rotate. Under the transmission action of the chain 15, the other sprocket 14 and the rotating shaft 13 will also rotate. The rotation of the chain 15 will drive the sliding seat 2 to slide along the annular slide 1 through the connecting rod 17, thereby realizing the transmission of the plastic-coated composite steel pipe hanging on the hook 8.

[0024] Both hooks 8 are fitted with anti-slip pads made of rubber. Rubber anti-slip pads have good elasticity and friction. When the plastic-coated composite steel pipe is hung on the hooks 8, the anti-slip pads can increase the friction between the steel pipe and the hooks 8, preventing the steel pipe from slipping due to vibration or other external forces during the transmission process, thus ensuring the safety and stability of the transmission process.

[0025] In this invention, a movable component drives two hooks 8 to approach each other, inserting one end of each hook 8 into both ends of the composite steel pipe. Then, the bidirectional cylinder 5 is activated. When the bidirectional cylinder 5 is working, its piston rods extend, causing two sliders 6 to approach each other on the sliding component. The sliding of the sliders 6 causes the support rod 7 to rotate, thereby raising the mounting base 4 and hanging the composite steel pipe on the conveyor frame. If the piston rods at both ends of the bidirectional cylinder 5 retract, the two sliders 6 move away from each other, thereby lowering the mounting base 4 until the composite steel pipe contacts the ground. This eliminates the need for manual lifting or simple tools to lift the plastic-coated composite steel pipe, significantly reducing the labor intensity of operators, avoiding the possibility of the steel pipe slipping during manual lifting, reducing the safety hazards of injuring operators or damaging equipment, and improving operational safety.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
