Description
Technical Field
[0001] The utility model belongs to the technical field of multi-layer board transportation, and specifically relates to a material cart with the function of turning over multi-layer boards. Background Art
[0002] A multi-layer board is a board made by gluing multiple thin wood slices or thin boards. It has excellent strength and stability and is usually composed of three or more layers. The wood grains of each layer of the multi-layer board are perpendicular and staggered with each other, which greatly enhances its ability to resist bending and deformation. It is widely used in the fields of furniture manufacturing, building decoration, etc. In short, the multi-layer board has become an ideal material choice for many industries due to its excellent performance. In the transportation of multi-layer boards, a material cart is generally used for handling operations.
[0003] A material cart usually consists of a frame, wheels, a tray, a handle, etc. The frame is mostly made of strong metal materials such as steel to provide sufficient support. The wheels generally include fixed wheels and swivel wheels for flexible movement and steering. The tray is used to place materials, and its area and load-bearing capacity are designed according to requirements. Its principle is based on simple mechanical motion. By pushing the handle manually, the wheels rotate, driving the entire material cart to move. When turning is required, the swivel wheels are operated to change the direction, and the stability of the material cart can be increased by adding brakes.
[0004] When the existing material cart is used for handling multi-layer boards, due to structural reasons, it cannot perform turning operations, which will lead to insufficient utilization of the space of the multi-layer boards and the material cart. In addition, since the material cart cannot turn over the multi-layer boards, the difficulty of loading and unloading the multi-layer boards will increase, resulting in an increase in transportation time and a threat to the safety of operators.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-5 As shown, a material cart with a multi-layer board flipping function includes a main frame vertical beam 1. The top end of the main frame vertical beam 1 is connected to a top pull rod 8. The other end of the top pull rod 8 is connected to a top fixing rod 4. The other end of the top fixing rod 4 is connected to a pneumatic rod 2. A first connecting rod 11 is provided in the middle of the two pneumatic rods 2. The other end of the first connecting rod 11 is connected to a handrail 6. Four first bottom cross beams 3 are provided at the bottom of the main frame vertical beam 1. A second bottom cross beam 7 is provided at the center bottom of the first bottom cross beam 3. Four casters 17 are provided at the four corners of the bottom end of the first bottom cross beam 3. The bottom of the top fixing rod 4 is slidably connected to a first double joint pipe 13. Seven first connecting ears 18 are fixedly connected to the outside of the first double joint pipe 13. The center of the first connecting ear 18 is connected to a first connecting plate 21. A cylinder 19 is provided at the other end of the first connecting plate 21. The output end of the cylinder 19 is connected to a pneumatic rod 23. The other end of the pneumatic rod 23 is connected to a second connecting plate 20. The other end of the second connecting plate 20 is connected to a fixed rotating shaft 22. One end of the fixed rotating shaft 22 intercepts a second connecting ear 24. The other end of the second connecting ear 24 is fixedly connected to a middle fixing rod 5. A third connecting rod 25 is provided at one end of the top connecting rod 9. When performing a flipping operation on the multi-layer board, at this time, the operator pushes the material cart to the position where flipping is required, and then starts the cylinder 19. At this time, the cylinder 19 will push the pneumatic rod 23. Subsequently, under the action of the pneumatic rod 23, the second connecting ear 24 is lifted. At this time, since the pneumatic rod 23 lifts, the second connecting ear 24 rotates around the fixed rotating shaft 22 as the axis, and thus the second connecting plate 20 pulls the middle fixing rod 5 to tilt up. During the tilting process, the first connecting plate 21 rotates around the first connecting ear 18 as the axis, thereby achieving the flipping effect, and the flipping angle can be adjusted by adjusting the position of the first double joint pipe 13. During this period, the third double joint pipe 15 and the second double joint pipe 14 are used to support the flipping structure to make the material cart tend to be stable. When the multi-layer board above the middle fixing rod 5 starts to flip, at this time, the top connecting rod 9 will be separated from the shock pad 12.
[0020] One side of the middle fixing rod 5 is fixedly connected with five top connecting rods 9. The bottom of the top connecting rod 9 is provided with five middle connecting rods 10. The two ends of the middle connecting rod 10 are fixedly connected to the center of the middle fixing rod 5. There is a shock pad 12 connected between each group of the middle fixing rods 5. One side of the pneumatic rod 2 is provided with a second double pipe 14. The other side of the pneumatic rod 2 is installed with a third double pipe 15. One side of the first double pipe 13 is provided with a secondary pipe 16. The secondary pipe 16 and the bottom end of the first double pipe 13 are connected to the third double pipe 15. There are two orientation plates outside the caster 17, and a brake is installed on the orientation plates outside the caster 17. When performing the turning operation on the multi-layer board, at this time, the operator pushes the armrest 6 to push the material cart to the position where turning is required. Only by adjusting the positions of the two orientation plates outside the caster 17, and then stepping on the brake outside the caster 17 to stabilize the device, can the position of the material cart be fixed, and then the reverse operation of the multi-layer board can be carried out.
[0021] Working principle: When performing the turning operation on the multi-layer board, at this time, the operator pushes the armrest 6 to push the material cart to the position where turning is required. Only by adjusting the positions of the two orientation plates outside the caster 17, and then stepping on the brake outside the caster 17 to stabilize the device, can the position of the material cart be fixed, and then the reverse operation of the multi-layer board can be carried out; When performing the turning operation on the multi-layer board, at this time, the operator pushes the material cart to the position where turning is required, and then starts the cylinder 19. At this time, the cylinder 19 will push the air pressure rod 23. Subsequently, under the action of the air pressure rod 23, the second connecting ear 24 is lifted. At this time, due to the lifting of the air pressure rod 23 driving the second connecting ear 24 to rotate around the fixed rotating shaft 22, and thus the second connecting plate 20 pulls the middle fixing rod 5 to tilt. During the tilting process, the first connecting plate 21 rotates around the first connecting ear 18, thereby achieving the turning effect, and the turning angle can be adjusted by adjusting the position of the first double pipe 13. During this period, the third double pipe 15 and the second double pipe 14 are used to support the turning structure to make the material cart tend to be stable; When the multi-layer board above the middle fixing rod 5 starts to turn, at this time, the top connecting rod 9 will separate from the shock pad 12, and thus the reverse operation of the multi-layer board is completed.
