Description

Technical Field

[0001] The utility model relates to the technical field of coil material feeding, in particular to a double-arm feeding vehicle for coil material transportation. Background Art

[0002] Coiled materials are widely used in packaging, construction, electronic product manufacturing, chemical industry, pharmaceutical industry and other fields. Coiled materials are large in size and weight, and transportation equipment is required for handling and loading.

[0003] After searching, the Chinese patent publication number CN213974142U discloses a labor-saving material roll transport device, including a frame and a cylindrical crossbeam. The cylindrical crossbeam is horizontally arranged and one end of which is fixedly installed on the frame. Several bearing mounting positions are distributed along the circumferential direction on the upper surface of the cylindrical crossbeam. Several bearings are installed on each bearing mounting position. Several bearings on each bearing mounting position are arranged and distributed along the axial direction of the cylindrical crossbeam. Each bearing on the bearing mounting position is equally higher than the circumferential surface of the cylindrical crossbeam in the radial direction.

[0004] This patent sets bearings, and when the material roll is moved to the cylindrical beam or unloaded from the cylindrical beam, the material roll can be pushed along the axial direction of the cylindrical beam to completely place the material roll on the cylindrical beam or unload it from the cylindrical beam. Since the bearings and the material roll have rolling friction, the friction force is small, and it is easy and labor-saving to push or push out. However, the height of the cylindrical beam is adjusted by horizontal threaded holes, through channels and bolts, which makes adjustment inconvenient, and when the cylindrical beam is raised, it needs to be lifted with force. If there is a material roll placed on the cylindrical beam at this time, a single person cannot raise the cylindrical beam. Utility Model Content

There is a V-shaped groove 10, a reinforcing rod 11 is fixed to the bottom end of the outer wall of one side of the slider 8, and the other end of the reinforcing rod 11 is connected to the support arm 9. The outer walls at both ends of the mounting plate 7 are relatively fixed with limiting plates 13, and the two limiting plates 13 are rotatably connected to the outer walls on one side of the opposite side with a bidirectional screw rod 14. The two sliders 8 are respectively connected to the two ends of the bidirectional screw rod 14 through threads with opposite rotation directions, and one end of the bidirectional screw rod 14 is connected to a hand wheel 15. The hydraulic cylinder 5 is fixed to the inner wall of the bottom surface of the lifting groove 4, and the telescopic end of the hydraulic cylinder 5 is connected to the lifting block 12.

[0029] During transportation, the hand wheel 15 is rotated according to the width of the coil, so that the slider 8 moves relatively along the bidirectional screw rod 14, and the distance between the support arms 9 is changed according to the width of the coil. Then, the hydraulic cylinder 5 drives the lifting block 12 to change its position according to the height of the coil reel, so that the support arm 9 is located below the reel. The push device is moved by the push handle 3 to align the V-shaped groove 10 with the two ends of the reel of the coil. The hydraulic cylinder 5 pushes the lifting block 12 to rise and lift the coil. The shape of the V-shaped groove 10 can make the coil slide along the side wall of the V-shaped groove 10 under gravity and get stuck inside the V-shaped groove 10. Then, the device is pushed to move as needed to transport the coil. When the transportation is completed, the hydraulic cylinder 5 raises or lowers the lifting block 12 as needed to change the height of the coil.

[0030] By arranging the hydraulic cylinder 5, the slide bar 6, the mounting plate 7, the slider 8, the support arm 9, the lifting block 12, the bidirectional screw rod 14 and the hand wheel 15, when transporting and loading materials, the hydraulic cylinder 5 pushes the lifting block 12 to adjust the height along the slide bar 6 to save manpower, and at the same time, the hand wheel 15 is rotated to make the slider 8 move relatively along the bidirectional screw rod 14, and the distance between the support arms 9 is changed according to the width of the coil, so that the support arms 9 can transport and lift coils of different widths.

[0031] By providing the V-shaped groove 10, the shape of the V-shaped groove 10 can make the coil slide along the side wall of the V-shaped groove 10 under gravity and get stuck inside the V-shaped groove 10, which can effectively limit the position of the coil and prevent the coil from being unstable during transportation.

[0032] Example 2

[0033] A double-arm loading vehicle for coil material transportation, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 2 and Figure 4 As shown, a locking assembly is arranged between the lifting slot 4 and the lifting block 12, and the locking assembly includes an installation cavity 25 and a limiting tooth 16 fixed to the inner wall of one side of the lifting slot 4, and the limiting teeth 16 are arranged in a straight line and equidistantly. The installation cavity 25 is opened on the outer wall of one side of the lifting block 12, and an electric push rod 20 is fixed to the inner wall of the bottom surface of the installation cavity 25. The telescopic end of the electric push rod 20 is provided with a cavity 22, and a moving block 23 is slidably connected to the inner wall of the cavity 22. A reset spring 24 is sleeved on the outer wall of the moving block 23, and a connecting rod 21 is fixed to one end of the moving block 23. Both ends of the connecting rod 21 are rotatably connected to the connecting rod 1 17, and both ends of the inner wall of the bottom surface of the installation cavity 25 are rotatably connected to the connecting rod 2 18, and the other end of the connecting rod 2 18 is rotatably connected to the connecting rod 1 17, and a fixing rod 19 is fixed to the outer wall of the opposite side of the two connecting rods 17, and the fixing rod 19 is limitedly matched with the limiting tooth 16.

[0034] When the lifting block 12 rises, the locking assembly rises with the lifting block 12, and the fixed rod 19 is squeezed by the outer wall of the bottom surface of the limiting tooth 16 and moves to the side away from the limiting tooth 16, so that the connecting rod 17 rotates with the axis of the connecting rod 21 as the rotation center and pushes the connecting rod 21 to move up, and the moving block 23 moves with the connecting rod 21, and the reset spring 24 is compressed, and the fixed rod 19 passes over a limiting tooth 16, and the reset spring 24 rebounds to reset the fixed rod 19. As the lifting block 12 rises, the fixed rod 19 repeats this step continuously. When the hydraulic cylinder 5 When a problem occurs and the lifting block 12 cannot be supported, the lifting block 12 falls due to gravity, the limit tooth 16 clamps the fixed rod 19, and the connecting rod 18 limits the rotation range of the fixed rod 19, so that the fixed rod 19 limits the lifting block 12 to prevent the lifting block 12 from falling suddenly and causing damage to people and property. When the lifting block 12 falls, the electric push rod 20 pushes the connecting rod 21 to rise, so that the fixed rod 19 retracts into the installation cavity 25. At this time, the fixed rod 19 will not limit the lifting block 12, so that the lifting block 12 can fall.

[0035] By setting up the locking assembly, when the hydraulic cylinder 5 has problems and cannot support the lifting block 12, the lifting block 12 falls due to gravity, the limit tooth 16 clamps the fixed rod 19, and the connecting rod 18 limits the rotation range of the fixed rod 19, so that the fixed rod 19 limits the lifting block 12 to prevent the lifting block 12 from falling suddenly and causing damage to people and property.

[0036] Working principle: During transportation, the hand wheel 15 is rotated according to the width of the coil, so that the slider 8 moves relatively along the bidirectional screw rod 14, and the distance between the support arms 9 is changed according to the width of the coil. Then, the hydraulic cylinder 5 drives the lifting block 12 to change its position according to the height of the coil reel, so that the support arm 9 is located below the reel, and the device is pushed to move by the push handle 3, and the V-shaped groove 10 is aligned with the two ends of the reel of the coil. The hydraulic cylinder 5 pushes the lifting block 12 to rise and lift the coil. The shape of the V-shaped groove 10 can make the coil slide along the side wall of the V-shaped groove 10 under gravity and get stuck inside the V-shaped groove 10. Then, the device is pushed to move as needed to transport the coil. When the transportation is completed, the hydraulic cylinder 5 raises or lowers the lifting block 12 as needed to change the height of the coil. When the lifting block 12 rises, the locking assembly rises with the lifting block 12, and the fixing rod 19 is squeezed by the outer wall of the bottom surface of the limiting tooth 16 and moves to the side away from the limiting tooth 16. , the connecting rod 17 rotates with the axis of the connecting rod 21 as the rotation center and pushes the connecting rod 21 to move up, the moving block 23 moves with the connecting rod 21, the reset spring 24 is compressed, the fixed rod 19 passes over a limit tooth 16, the reset spring 24 rebounds, and the fixed rod 19 is reset. As the lifting block 12 rises, the fixed rod 19 repeats this step continuously. When the hydraulic cylinder 5 has a problem and cannot support the lifting block 12, the lifting block 12 falls under gravity, the limit tooth 16 clamps the fixed rod 19, and the connecting rod 2 18 limits the rotation range of the fixed rod 19, so that the fixed rod 19 limits the lifting block 12 to prevent the lifting block 12 from falling suddenly and causing damage to personnel and property. When the lifting block 12 falls, the electric push rod 20 pushes the connecting rod 21 to rise, so that the fixed rod 19 retracts into the installation cavity 25. At this time, the fixed rod 19 will not limit the lifting block 12, so that the lifting block 12 can fall.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
