Description

Technical Field

[0001] This utility model relates to the technical field of aluminum coil turnover equipment, and in particular to an aluminum coil loading and unloading trolley. Background Technology

[0002] As is well known, in the finishing process of aluminum alloys, after the previous finishing process, it needs to be transferred to the next finishing process. Between the two finishing processes, the coil material from the previous finishing process needs to be transferred to the next finishing process. Currently, the process of transferring the coil material is carried out by an uncoiling trolley. The uncoiling trolley takes the coil material from the coiler and then moves it to the uncoiling machine position of the next finishing process.

[0003] In the existing technology, the clamping structure of the existing aluminum coil trolley is relatively complex. Some aluminum coil trolleys use a manual clamping method, which requires personnel to frequently tighten and unlock the clamping structure, causing inconvenience to the loading and unloading of aluminum coils. Moreover, due to the limited contact area between the clamping structure and the aluminum coil, there are safety hazards. Secondly, the device used to support the aluminum coil on the unloading trolley does not have an angle adjustment structure. During the turnover of aluminum coils, the angle may need to be adjusted during the unloading process due to the different installation positions of the coiler and the uncoiler, which increases the difficulty of aluminum coil turnover.

[0004] To address this issue, a loading and unloading trolley for aluminum coils was proposed, which has the advantages of easy adjustment of the aluminum coil unloading angle, loading and unloading efficiency, and high safety, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an aluminum coil loading and unloading trolley.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum coil unloading trolley, including an unloading trolley, wherein a hydraulic lift is fixedly installed at the bottom of the unloading trolley, and wheels are installed at the bottom of the hydraulic lift. An arc-shaped groove is opened on the top surface of the unloading trolley, and grooves are opened on both the left and right sides inside the arc-shaped groove. A second electric cylinder is fixedly installed in the groove, and a fastening block is fixed to one end of the second electric cylinder by bolts. Two vertical plates are symmetrically welded on the top surface of the unloading trolley, and a first electric cylinder is fixedly installed on the surface of each vertical plate. An arc-shaped clamping plate is fixed to one end of the first electric cylinder by bolts. A drive shaft is welded to the bottom of the unloading trolley, and a large gear is fixed to the bottom of the drive shaft. A receiving cavity is opened in the support panel at the top of the hydraulic lift, and a servo motor is fixedly installed in the receiving cavity. A small gear that meshes with the large gear is fixed to the output end of the servo motor.

[0007] As a further description of the above technical solution: two parallel sliding grooves are provided on the bottom surface of the inner side of the groove, and two T-shaped sliders are fixed at the bottom of the fastening block corresponding to the sliding grooves. The T-shaped sliders are slidably connected to the sliding grooves in the groove.

[0008] As a further description of the above technical solution: two fastening blocks are provided, and the opposing ends of the two fastening blocks are provided with arc-shaped surfaces.

[0009] As a further description of the above technical solution: both the unloading trolley and the vertical plate are made of 7075 aluminum alloy, and several reinforcing ribs are welded and installed at the connection between the unloading trolley and the vertical plate.

[0010] As a further description of the above technical solution: the hydraulic lift is specifically an OmniTitan series self-lifting platform or an electro-hydraulic linkage outrigger lifting platform.

[0011] As a further description of the above technical solution: the fastening block is located entirely inside the arc-shaped groove, and the fastening block is located below the arc-shaped clamping plate.

[0012] This utility model has the following beneficial effects: In this invention, by activating the extension of the first electric cylinders of the two vertical plates, the two first electric cylinders respectively push the corresponding arc clamps closer to the aluminum coil in the unloading trolley, so that the two arc clamps respectively abut against the two sides of the aluminum coil. At this time, by activating the extension of the two second electric cylinders symmetrically installed in the arc groove, the two second electric cylinders respectively push the corresponding fastening blocks to move towards each other, so that the arc surfaces of the two fastening blocks at the opposite ends abut against the lower side of the aluminum coil placed in the middle of the arc groove. Combined with the hydraulic lift fixedly installed at the bottom of the unloading trolley and the wheels installed at the bottom of the hydraulic lift, it is not only convenient for reliable clamping of the aluminum coil, but the electric drive clamping method is also convenient for rapid loading and unloading of the aluminum coil, and also meets the height adjustment and position turnover of the aluminum coil loading and unloading. In this invention, a receiving cavity is provided in the support panel at the top of the hydraulic lift, and a servo motor is installed in the receiving cavity. The small gear at the output end of the servo motor meshes with the large gear at the bottom of the transmission shaft. By starting the servo motor in the receiving cavity, the servo motor drives the small gear to rotate, which in turn drives the large gear to rotate, causing the transmission shaft to drive the unloading carriage to rotate. This enables the adjustment of the angle of the aluminum coil on the unloading carriage, avoiding the problem of increased difficulty in unloading aluminum coils due to different installation positions of the coiler and the uncoiler.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] According to an embodiment of the present invention, an aluminum coil loading and unloading trolley is provided.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the aluminum coil unloading trolley according to an embodiment of the present invention includes an unloading trolley 1. A hydraulic lift 2 is fixedly installed at the bottom of the unloading trolley 1, and wheels 3 are installed at the bottom of the hydraulic lift 2. An arc-shaped groove 12 is formed on the top surface of the unloading trolley, and grooves 13 are formed on both the left and right sides inside the arc-shaped groove 12. A second electric cylinder 14 is fixedly installed in the groove 13, and a fastening block 15 is fixed to one end of the second electric cylinder 14 by bolts. Two vertical plates 9 are symmetrically welded to the top surface of the unloading trolley 1, and a first electric cylinder 10 is fixedly installed on the surface of each vertical plate 9. An arc-shaped clamping plate 11 is fixed to one end of the first electric cylinder 10 by bolts. A drive shaft 7 is welded to the bottom of the unloading trolley 1, and a large gear 8 is fixed to the bottom of the drive shaft 7. A receiving cavity 4 is formed in the support panel at the top of the hydraulic lift 2, and a servo motor is fixedly installed in the receiving cavity 4. 5. The output end of the servo motor 5 is fixed with a small gear 6 that meshes with the large gear 8. In this patent, we only use the hydraulic lift 2, the servo motor 5, the first electric cylinder 10, and the second electric cylinder 14 without improving their structure and function. For those skilled in the art, the setting method, installation method, and electrical connection method can be debugged and operated according to the requirements of the instruction manual, so they will not be described in detail here. The hydraulic lift 2, the servo motor 5, the first electric cylinder 10, and the second electric cylinder 14 are all equipped with their matching control switches. The installation position of the control switches can be selected according to the actual use requirements to facilitate the operation and control by the operator. The principle of the hydraulic lift 2 is an existing known technology and there are mature products. Therefore, its principle will not be explained further. In one embodiment, two parallel sliding grooves 16 are provided on the inner bottom surface of the groove 13, and two T-shaped sliders 17 are fixed to the bottom of the fastening block 15 corresponding to the sliding grooves 16. The T-shaped sliders 17 are slidably connected to the sliding grooves 16 in the groove 13. This structure increases the stability of the movement of the fastening block 15.

[0018] In one embodiment, two fastening blocks 15 are provided, and the opposing ends of the two fastening blocks 15 are provided with arc-shaped surfaces 18. This structure increases the fit between the fastening blocks 15 and the side of the aluminum coil. In order to increase the anti-slip effect, grid-shaped anti-slip ridges are also provided on the arc-shaped surfaces 18.

[0019] In one embodiment, both the unloading carriage 1 and the vertical plate 9 are made of 7075 aluminum alloy, and several reinforcing ribs are welded and installed at the connection between the unloading carriage 1 and the vertical plate 9. This structure increases the structural strength of the vertical plate 9 and reduces the impact of the aluminum coil on the vertical plate 9.

[0020] In one embodiment, the hydraulic lift 2 is specifically an OmniTitan series self-lifting platform or an electro-hydraulic linkage outrigger lifting platform. The OmniTitan series self-lifting platform or electro-hydraulic linkage outrigger lifting platform is used to lift aluminum coils with a weight of more than 30 tons, with reliable lifting effect and high safety factor.

[0021] In one embodiment, the fastening block 15 is located entirely inside the arc-shaped groove 12 and below the arc-shaped clamping plate. This structure enables secondary clamping of the aluminum coil and maintains the reliability of the aluminum coil installation.

[0022] Working principle: In use, the unloading trolley 1 first receives the coil from the coiler. When clamped and fixed, the first electric cylinders 10 of the two vertical plates 9 are extended, causing the two first electric cylinders 10 to push the corresponding arc clamps 11 closer to the aluminum coil inside the unloading trolley 1, so that the two arc clamps 11 abut against the two sides of the aluminum coil. At this time, the two second electric cylinders 14 symmetrically installed in the arc groove 12 are extended, causing the two second electric cylinders 14 to push the corresponding fastening blocks 15 to move towards each other, so that the arc surfaces 18 of the two fastening blocks 15 facing each other abut against the lower side of the aluminum coil placed in the middle of the arc groove 12, thus achieving reliable clamping of the aluminum coil and preventing the aluminum coil from falling off. Combined with the bottom of the unloading trolley 1, the unloading trolley 1 is fixed. The fixed-mount hydraulic lift 2 and the wheels 3 installed at the bottom of the hydraulic lift 2 facilitate the height adjustment and position turnover of the aluminum coil unloading. Then, the unloading cart 1 moves to the position of the uncoiler in the next finishing process. Then, the arc clamp 11 and the fastening block 15 are unlocked to clamp the aluminum coil. At this time, the servo motor 5 in the receiving cavity 4 is started to work, which causes the servo motor 5 to drive the small gear 6 to rotate. In turn, the small gear 6 drives the large gear 8 to rotate, so that the transmission shaft 7 drives the unloading cart 1 to rotate, realizing the adjustment of the angle of the aluminum coil on the unloading cart 1. This makes the angle of the aluminum coil match the installation position of the uncoiler, avoiding the problem of increased difficulty in unloading aluminum coil due to the different installation positions of the coiler and the uncoiler.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
