Description

Technical Field

[0001] This utility model relates to the field of steel coil production technology, and more specifically, to a lifting steel coil conveyor vehicle. Background Technology

[0002] A steel coil conveyor is a specialized piece of equipment used for transporting steel coils, and it is widely used in steel production, logistics, and other fields. Typically, the lifting mechanism of a steel coil conveyor uses a box-frame structure or a guide rod, and the length of these types of lifting mechanisms, including the box-frame and guide rod, is determined by the lifting stroke of the steel coil conveyor.

[0003] Patent document CN217200357U discloses an automatic feeding device for steel coils. By setting guide rails, the device can move stably on the guide rails, and horizontal and lifting drive components provide sufficient power for the feeding process. During operation, the lead screw rises and falls under the action of a worm gear, thereby raising and lowering the support.

[0004] With similar lifting structures, the longer the lifting stroke of the steel coil cart, the longer the box frame and guide rods become. This increases the size and structure of the steel coil cart, necessitating adjustments to the equipment layout in the uncoiling and winding areas or lengthening the drum to meet the required installation space, ultimately increasing the installation and operating costs. While using a scissor lift mechanism can reduce size and lower the installation and operating costs of the conveyor, the scissor structure is prone to swaying during lifting. As the lifting height increases, the amplitude of swaying also increases, causing the steel coil to shake. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a lifting steel coil conveyor that reduces the size of the conveyor vehicle by using a scissor lift, while limiting the scissor structure to reduce swaying during the lifting process and improve the stability of the conveyor vehicle.

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

[0007] A lifting steel coil conveyor includes a mobile trolley, a lifting assembly on top of the mobile trolley, and a support platform on top of the lifting assembly. The lifting assembly includes two mounting frames arranged vertically, a scissor structure disposed between the mounting frames, and a hydraulic cylinder connected to the scissor structure. Each mounting frame includes a mounting crossbar and a mounting longitudinal bar connected to each other. The scissor structure is symmetrically arranged and includes a first scissor bar and a second scissor bar rotatably connected. A rotating connecting rod is provided between the first scissor bar and the second scissor bar. Stabilizing members are connected to both ends of the rotating connecting rod connecting the ends of the first scissor bar and the second scissor bar. The stabilizing members are symmetrically arranged about the mounting frames and include a stabilizing block disposed on the side wall of the rotating connecting rod and a stabilizing connecting rod slidably connected to the stabilizing block.

[0008] The present invention is further configured such that: multiple scissor structures are provided between the two mounting brackets, and each scissor structure is rotatably connected to the others.

[0009] The present invention is further configured such that: the first scissor bar and the second scissor bar are rotatably connected at their middle parts; the end of the first scissor bar is rotatably connected to the end of the second scissor bar on another scissor bar structure; and the end of the second scissor bar is rotatably connected to the first scissor bar on another scissor bar structure.

[0010] The present invention is further configured such that: the rotating connecting rod is arranged along the direction of the mounting crossbar, and both the mounting crossbar and the mounting longitudinal bar are rotatably sleeved on both ends of the rotating connecting rod.

[0011] The present invention is further configured such that: a sliding block is provided on the side of the scissor structure near the mounting rod, and the sliding block is slidably engaged with the mounting rod.

[0012] By adopting the above technical solution, when the scissor lift structure is raised or lowered, the movement of both ends of the first and second scissor arms synchronously drives the connected rotating link to move along the horizontal plane. During the movement of the rotating link, the stabilizing block synchronously slides along the slide groove. During the raising and lowering process of the scissor lift structure, the sliding of the stabilizing block along the slide groove, through the stabilizing link, limits the sliding of the first and second scissor arms in the horizontal plane.

[0013] The present invention is further configured such that: the stabilizing link is arranged along the direction of the first scissor bar, the stabilizing link is provided with a sliding groove, and the stabilizing block is slidably installed inside the sliding groove.

[0014] The present invention is further configured such that: the mounting frame is a rectangular structure, and the mounting frame is formed by connecting two mounting crossbars and two mounting longitudinal bars.

[0015] The present invention is further configured such that: the supporting platform includes an installation plate connected to the lifting assembly and a support plate rotatably mounted on the installation plate; steel coil pads are symmetrically arranged on the support plate, and the steel coil pads are inclined toward one side of the axis of the support plate.

[0016] The present invention is further configured such that: a rotary assembly is provided between the mounting plate and the support plate, the rotary assembly including a rotary bearing mounted on the mounting plate and a drive component disposed through the mounting plate.

[0017] The beneficial effects of this utility model are:

[0018] During the lifting and lowering process of the scissor lift structure, the sliding of the stabilizing block along the slide groove and the use of the stabilizing connecting rod limit the sliding of the first and second scissor lifts in the horizontal direction, reducing the possibility of swaying of the first and second scissor lifts during the lifting and lowering process and improving the overall stability of the scissor lift structure during the lifting and lowering process.

[0035] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] Please refer to Figure 1-4 A lifting steel coil conveyor 10 includes a mobile platform 1, a lifting assembly 2 located on top of the mobile platform 1, and a support platform 3 located on top of the lifting assembly 2. The conveyor 10 is arranged along a track 20, and a steel coil 30 is placed on top of the conveyor 10. During the movement of the conveyor 10 along the track 20, the steel coil 30 is conveyed.

[0037] Please refer to Figure 1-4 A motor 13 is mounted on the side wall of the mobile cart 1. A bevel gear is connected to the output end of the motor 13. Two connecting rods 12 are rotatably mounted on the bottom of the mobile cart 1, and the connecting rods 12 are arranged along the vertical track 20. A bevel gear 14 is fitted onto one of the connecting rods 12, and the bevel gear 14 on the connecting rod 12 meshes with the bevel gear 14 at the output end of the motor 13. A wheel 11 is located at each end of the connecting rod 12, and the wheels 11 can roll along the track 20, thereby moving the mobile cart 1. The motor 13 can drive the bevel gear 14 to rotate, and through the meshing of the bevel gears 14, it drives the connecting rod 12 to rotate, thereby driving the wheels 11 to roll along the track 20, realizing the movement of the mobile cart 1.

[0038] Please refer to Figure 4-7 The lifting assembly 2 includes two mounting frames 21 symmetrically arranged along a horizontal plane, a scissor structure 22 disposed between the mounting frames 21, and a hydraulic cylinder 24 connected to the scissor structure 22. The two mounting frames 21 are respectively located at the top and bottom of the scissor structure 22. The hydraulic cylinder 24 can drive the scissor structure 22 to move, thereby achieving lifting and lowering. The mounting frame 21 includes a mounting crossbar 211 and a mounting longitudinal bar 212 connected to each other. The mounting frame 21 has a rectangular structure and is formed by connecting the two mounting crossbars 211 and the two mounting longitudinal bars 212. The two mounting frames 21 are respectively located at the top and bottom of the scissor structure 22. The mounting frame 21 located at the bottom of the scissor structure 22 is connected to the mobile trolley 1, and the mounting frame 21 located at the top of the scissor structure 22 is connected to the supporting platform 3. The lifting and lowering of the supporting platform 3 relative to the mobile trolley 1 is achieved by moving the scissor structure 22. It should be noted that in actual use, the number of scissor lift structures 22 can be selected according to the lifting stroke requirements of the conveyor 10 to meet the needs of different lifting strokes.

[0039] Please refer to Figure 4-7 The scissor lift structures 22 are symmetrically arranged about the mounting brackets 21 and are positioned along the mounting longitudinal rod 212. Multiple scissor lift structures 22 are vertically arranged between the two mounting brackets 21, and each scissor lift structure 22 is rotatably connected to the others. Each scissor lift structure 22 includes a first scissor lift 221 and a second scissor lift 222 rotatably connected, with a rotating connecting rod 223 between them. The first scissor lift 221 and the second scissor lift 222 are rotatably connected at their midpoints. During rotation around this midpoint, the distance between the ends of the first scissor lift 221 and the second scissor lift 222 changes, thus achieving the raising and lowering of the scissor lift structure 22. The end of the first scissor lift 221 is rotatably connected to the end of the second scissor lift 222 on another scissor lift structure 22, and the end of the second scissor lift 222 is rotatably connected to the first scissor lift 221 on another scissor lift structure 22, thereby achieving the connection between the multiple scissor lift structures 22.

[0040] Please refer to Figure 4-7The rotating connecting rod 223 is arranged along the direction of the mounting crossbar 211. The first scissor lift 221 and the second scissor lift 222 both have rotating connecting rods 223 at their ends and middle. The rotating connecting rod 223 passes through the middle of the first scissor lift 221 and the second scissor lift 222. Both ends of the first scissor lift 221 and the second scissor lift 222 are sleeved on both ends of the rotating connecting rod 223. The rotating connecting rod 223 connects the symmetrically arranged scissor lift structures 22, ensuring that the symmetrically arranged scissor lift structures 22 can move synchronously. The mounting crossbar 211 and the mounting longitudinal bar 212 are both rotatably sleeved on both ends of the rotating connecting rod 223. A sliding block 224 is provided on the scissor lift structure 22 near the mounting longitudinal bar 212, and the sliding block 224 is connected to the end of the rotating connecting rod 223. Specifically, two of the multiple scissor lift structures 22, located at the top and bottom, are equipped with sliding blocks 224 near the mounting rod 212. These sliding blocks 224 are slidably engaged with the mounting rod 212. The sliding blocks 224 can move along the mounting rod 212, and this movement synchronously drives the multiple scissor lift structures 22, thus completing the lifting and lowering process.

[0041] Please refer to Figure 4-7 A rotating connecting rod 223, connecting the ends of the first scissor lift 221 and the second scissor lift 222, is equipped with stabilizing members 25 at both ends. The stabilizing members 25 are symmetrically arranged about the mounting frame 21. Each stabilizing member 25 includes a stabilizing block 253 located on the side wall of the rotating connecting rod 223 and a stabilizing connecting rod 251 slidably connected to the stabilizing block 253. The stabilizing blocks 253 are fixedly connected to the rotating connecting rod 223 and are respectively located at both ends of the rotating connecting rod 223. The stabilizing connecting rods 251 are arranged along the direction of the first scissor lift 221, and the two stabilizing connecting rods 251 are symmetrically arranged about the mounting frame 21. A groove 252 is provided on the stabilizing connecting rod 251, the shape of which is adapted to the stabilizing block 253, allowing the stabilizing block 253 to slide inside the groove 252. The length of the stabilizing connecting rod 251 is greater than the length of the groove 252, using both ends of the stabilizing connecting rod 251 to limit the stabilizing block 253 within the groove 252, preventing the stabilizing block 253 from slipping out. When the scissor lift structure 22 is raised or lowered, the movement of the first scissor bar 221 and the second scissor bar 222 simultaneously drives the connected rotating link 223 to move in the horizontal direction. During the movement of the rotating link 223, the stabilizing block 253 simultaneously slides along the slide groove 252. During the raising or lowering process of the scissor lift structure 22, the sliding of the stabilizing block 253 along the slide groove 252, along with the stabilizing link 251, limits the sliding of the first scissor bar 221 and the second scissor bar 222 in the horizontal direction, reducing the possibility of swaying during the raising or lowering process and improving the overall stability of the scissor lift structure 22 during this process.

[0042] Please refer to Figure 4-7A hydraulic cylinder 24 is connected to the middle of a rotating connecting rod 223 that is connected to the end of the scissor lift structure 22 located at the bottom. The end of the hydraulic cylinder 24 is sleeved on the rotating connecting rod 223, and the other end of the hydraulic cylinder 24 is connected to a hydraulic pump 23. The hydraulic pump 23 is located on one side of the mounting frame 21 and is mounted on the top of the mobile trolley 1. The hydraulic pump 23 can drive the hydraulic cylinder 24 to extend and retract. During the extension and retraction of the hydraulic cylinder 24, the rotating connecting rod 223 can drive the sliding block 224 on the scissor lift structure 22 to move along the mounting longitudinal rod 212. During the movement of the sliding block 224, the first scissor lift 221 and the second scissor lift 222 around the middle connection point. At this time, the distance between the ends of the first scissor lift 221 and the second scissor lift 222 will change accordingly, thereby realizing the lifting and lowering of the scissor lift structure 22. Finally, the lifting and lowering of multiple scissor lift structures 22 drives the support platform 3 to lift and lower relative to the mobile trolley 1.

[0043] The lifting and lowering caused by the rotation of the scissor structure 22 drives the support platform 3 to lift and lower relative to the moving trolley 1. When the scissor structure 22 rises, it can fully guarantee the lifting and lowering stroke of the conveyor 10. When lifting and lowering is not required, the scissor structure 22 can be retracted. The volume after retraction and folding is smaller than that of traditional lifting structures, thereby reducing the volume of the conveyor 10 and thus reducing the installation and use cost of the conveyor 10.

[0044] Please refer to Figure 1-4 The support platform 3 includes a mounting plate 31 connected to the lifting assembly 2 and a support plate 32 rotatably mounted on the mounting plate 31. The mounting plate 31 is connected to the mounting frame 21 and can be raised and lowered synchronously with the mounting frame 21. Steel coil pads 33 are symmetrically arranged on the support plate 32. The steel coil pads 33 are hollow triangular steel structures and are inclined towards one side of the axis of the support plate 32. Multiple support beams 34 are arranged inside the steel coil pads 33, and the support beams 34 are perpendicular to the top of the support plate 32. A steel coil 30 is placed between two steel coil pads 33, with the top of the steel coil pads 33 in contact with the steel coil 30. The support beams 34 support the steel coil 30, improving the load-bearing capacity of the steel coil pads 33.

[0045] Please refer to Figure 1-4 A rotating assembly 4 is provided between the mounting plate 31 and the support plate 32. The rotating assembly 4 can drive the support plate 32 to rotate relative to the mounting plate 31, thereby turning the steel coil 30. The rotating assembly 4 includes a slewing bearing 42 mounted on the mounting plate 31 and a driving component 41 that penetrates the mounting plate 31. The driving component 41 is a structure well known to those skilled in the art, and is not specifically limited herein. In actual use, a hydraulic drive or an electric motor drive or other corresponding drive structure can be adopted. The driving component 41 can drive the slewing bearing 42 to rotate. During the rotation of the slewing bearing 42, it can synchronously drive the support plate 32 to rotate relative to the mounting plate 31, ultimately turning the steel coil 30.
