Abstract
Description
Technical Field
[0001] This application relates to the technical field of steel rolling production equipment, and more particularly to a coil handling trolley using a rolling mill. Background Technology
[0002] In the field of precision rolling of sheet metal, the efficiency and safety of coil handling directly affect production progress and worker safety. Traditionally, coil handling involves manual labor in conjunction with hoisting equipment to load and unload the coils onto a transport trolley. Once placed on the trolley, the coil is directly transported to the designated location. However, the trolley lacks auxiliary restraint and locking mechanisms for the coils. Consequently, instability or sudden stops on the trolley can easily cause the coils to shift or even tip over, posing significant safety hazards. To address these issues, those skilled in the art urgently need to develop a new type of coil handling trolley for use in rolling mills to meet diverse practical needs. Utility Model Content

[0023] Compared with the prior art, the above application has the following advantages:
[0024] This application utilizes a coil handling trolley for a rolling mill, which, by setting up left and right clamping devices, can effectively limit and secure the coil on both sides during the handling process.

[0032] like Figures 1 to 3As shown, a coil handling trolley for use in rolling mills includes a trolley body 100, a loading seat 200 disposed on the upper side of the trolley body 100 for loading coils, a lifting drive device 300 disposed on the trolley body 100 and connected to the loading seat 200, a left clamping device 400 disposed on the left side of the loading seat 200, and a right clamping device 500 disposed on the right side of the loading seat 200.
[0033] This application, by setting a left clamping device 400 and a right clamping device 500, can effectively limit and secure the left and right sides of the coil material during the handling process, thereby avoiding the problem of the coil material shifting or even tipping over when the handling trolley is unstable or stops suddenly. This can further reduce safety hazards and improve the safety and stability of the coil material handling process.
[0034] Furthermore, the left clamping device 400 includes a left guide tube 41, a left front limiting plate 42, a left front drive group 43, a left rear limiting plate 44, and a left rear drive group 45.
[0035] The left conduit 41 is located on the left side of the mounting base 200, and has a through groove 411 extending from front to back. The left front limiting plate 42 is slidably connected to the front side of the left conduit 41 and is inclined to the right. The left front drive assembly 43 is located on the left front side of the mounting base 200, and its rear end extends into the left conduit 41. The rear end of the left front drive assembly 43 has a left front connecting part 431 located in the left through groove 411 for connecting with the left front limiting plate 41. The left rear limiting plate 44 is slidably connected to the rear side of the left conduit 41 and is inclined to the right. The left rear drive assembly 45 is located on the left rear side of the mounting base 200, and its front end extends into the left conduit 41. The front end of the left rear drive assembly 45 has a left rear connecting part 451 located in the left through groove 411 for connecting with the left rear limiting plate 44.
[0036] The working principle of the left clamping device 400 is to use a hollow left guide tube 41, and to open a left through groove 411 on the left guide tube 41. The power output end of the left front drive group 43 is located inside the left guide tube 41, and is connected to the left front limiting plate 42 through the left front connecting part 431, so that the left front limiting plate 42 can be driven to slide back and forth. At the same time, the power output end of the front end of the left rear drive group 45 is also located inside the left guide tube 41, and is connected to the left rear limiting plate 44 through the left rear connecting part 451, so as to drive the left rear limiting plate 44 to slide back and forth. Thus, the left side of the coil can be effectively limited and fixed by the synchronous opposite sliding of the left front limiting plate 42 and the left rear limiting plate 44, or the left side of the coil can be effectively released by the synchronous opposite sliding of the two, thereby facilitating the loading and unloading operation of the coil.
[0037] In addition, this application sets the power output end at the rear of the left front drive group 43 and the power output end at the front of the left rear drive group 45 inside the left guide tube 41. The advantage is that it can effectively reduce the occupation of external space, making the overall structure more compact. At the same time, it can also simplify the structure, reduce the number of parts used, thereby reducing manufacturing costs and maintenance difficulty.
[0038] Furthermore, both the left front drive group 43 and the left rear drive group 45 can be electric drive cylinders, pneumatic drive cylinders, or hydraulic drive cylinders, depending on the actual usage requirements.
[0039] Furthermore, the left clamping device 400 and the right clamping device 500 are arranged symmetrically on the left and right sides. Therefore, the structure of the right clamping device 500 is the same as that of the left clamping device 400, and the connection method and working principle between its components are the same as those of the left clamping device 400. Therefore, they will not be described in detail again.
[0040] Furthermore, the upper side of the mounting base 200 is provided with a V-shaped recess 21. The V-shaped recess 21 can effectively accommodate rolls of material of different diameters, making them more stable when placed; at the same time, the inclined surfaces on both sides of the V-shaped recess 21 can guide the roll of material, facilitating automatic centering of the roll of material, thereby improving loading and unloading efficiency.
[0041] In addition, the bottom of the V-shaped recess 21 is provided with a buffer pad layer (not shown in the figure). The buffer pad layer can effectively protect the bottom of the roll from damage, and at the same time provide a certain buffering effect during the placement of the roll, reducing the impact of the impact on the roll.
[0042] Furthermore, the vehicle body 100 includes a frame 11, a wheel set 12, and a motion drive set 13;
[0043] There are at least two sets of wheels 12, which are arranged at an interval between the front and rear on the underside of the frame 11. The moving drive assembly 13 is mounted on the frame 11 and connected to the wheel sets 12, and is used to drive the wheel sets 12 to move the frame 11 back and forth. The moving drive assembly 13 consists of a drive motor, a drive gear, and a transmission gear. The transmission gear is mounted on the axle of the wheel set 12, and the drive gear meshes with the transmission gear to achieve the driving effect.
[0044] Furthermore, the vehicle body 100 also includes a left protective cover 14 and a right protective cover 15 respectively disposed on the left and right sides of the wheel assembly 12. The design of the left protective cover 14 and the right protective cover 15 not only improves the overall aesthetics of the equipment, but also effectively prevents external debris from entering the wheel assembly 12, avoiding problems such as sudden stop of operation due to foreign object jamming, thereby ensuring the stability and safety of equipment operation.
[0045] Furthermore, the lifting drive device 300 includes a lifting drive assembly 31, a guide sleeve 32, and a guide column 33;
[0046] The lifting drive assembly 31 is located in the middle of the vehicle body 100, and its upper end is connected to the lower side of the mounting seat 200; the lifting drive assembly 31 is a hydraulic drive cylinder.
[0047] There are multiple sets of guide sleeves 32, all of which are located around the lifting drive group 31.
[0048] The number of guide posts 33 is equal to the number of guide sleeves 32, and the lower end of each guide post 33 is slidably connected to each guide sleeve 32, and its upper end is connected to the lower side of the mounting base 200.
[0049] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
