It usually includes two functions of longitudinal shearing and transverse shearing. Longitudinal shearing is mainly used to cut metal coil plate into strip material of required width, and these strip materials can be rewound for use in the next process, which is commonly used in the precision shearing of metal strip material in transformer and motor industries. Transverse shearing is used to cut metal coil plate into flat plate material of required length and stack, which is suitable for sizing transverse shearing operation of various metal materials such as cold-rolled and hot-rolled carbon steel, silicon steel and stainless steel. The longitudinal and transverse shearing machine has the advantages of simple operation, good cutting quality and high material utilization rate. It is usually composed of unwinding, leveling, shearing, discharging and other devices, and is equipped with storage pit, traction deviation correction device, roller type transition slide and other online mechanisms to form a complete production line.
[0003] At present, the heavy steel coil is installed on the uncoiler in the form of crane lifting, that is, the steel coil is lifted by the crane, and the steel coil is slowly moved to the steel coil sleeve shaft of the uncoiler under the assistance of manual. This method needs manual feeding throughout the process, and the stability of the steel coil is poor when it is suspended, which is easy to cause injury to personnel due to swinging, and when the core of the steel coil is sleeved with the steel coil sleeve shaft of the uncoiler, there is also swinging due to suspension, so it is not possible to directly sleeve the steel coil sleeve shaft accurately, and even it may cause violent impact with the steel coil sleeve, thereby causing damage to the uncoiler.
[0004] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. UTILITY MODEL CONTENTS
[0005] The utility model aims at overcoming the problems of the prior art, and provides a steel coil feeding and discharging auxiliary trolley, which is used to solve the problems that when manually sleeving the steel coil with the uncoiler, the stability of the steel coil is poor due to suspension by the crane, which is easy to cause injury to personnel, and it is not possible to accurately position the steel coil sleeve shaft of the uncoiler, which is easy to cause impact and damage to the uncoiler.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0035] like Figures 1-3 As shown, a steel coil loading and unloading auxiliary trolley includes a V-shaped platform 1 arranged vertically and a base 2 with a cavity 201. A vertical lifting cylinder 3 is arranged at the axial position of the base 2, and the piston end of the lifting cylinder 3 is connected to a cylinder connector 4 arranged at the axial position of the bottom surface of the V-shaped platform 1.
[0036] A pair of wheel assemblies 5 are provided on the base 2, and a wheel drive motor 6 is provided on the bottom surface of the base 2. The wheel drive motor 6 can drive the wheel assembly 5 to move the V-shaped platform 1 horizontally.
[0037] like Figure 4 and Figure 5 As shown, specifically, a groove 9 is pre-cut in the ground directly below the steel coil shaft 701 of the uncoiler 7, and a double track 10 for the wheel assembly 5 is set in the groove 9. In this embodiment, the wheel assembly 5 can move horizontally on the double track 10 under the drive of the wheel drive motor 6.
[0038] The end of the double track 10 of the wheel, which is far away from the coiler 7, serves as the feeding end of the steel coil. The cylindrical steel coil is directly hoisted onto the V-shaped platform 1 by a crane. Then, the wheel drive motor 6 is controlled by the electronic control system to drive the wheel assembly 5 to move horizontally on the double track 10 of the wheel, thereby moving the steel coil to the outer end of the steel coil sleeve shaft 701 of the uncoiler.
[0039] Then, the lifting cylinder 3 is controlled by the electronic control system to drive the V-shaped platform 1 to rise and fall until the core of the steel coil corresponds with the steel coil sleeve shaft 701. Then, the wheel assembly 5 is controlled to move horizontally to one side of the steel coil sleeve shaft 701, so as to achieve automatic and precise steel coil feeding without human contact.
[0040] like Figure 1 As shown, in this embodiment, the wheel assembly 5 includes a wheel shaft 501 that can movably pass through the cavity 201. The two ends of the wheel shaft 501 extend out of the wheel side 202 of the base 2 and are respectively sleeved with the wheel 502. A wheel sprocket 503 is provided on the inner side of any wheel 502.
[0041] Correspondingly, a motor sprocket 601 is sleeved on the shaft of the wheel drive motor 6, and the motor sprocket 601 is connected to the wheel sprocket 503 by a chain.
[0042] In this embodiment, the drive motor 6 of the wheel is controlled by the electronic control system. The motor sprocket 601 drives the wheel sprocket 503 to rotate through the chain. Since the wheel sprocket 503 is sleeved on the wheel shaft 501, its rotation will inevitably drive the wheel shaft 501 and the wheels 502 at both ends to rotate, and finally drive the four wheels 502 of the trolley to move.
[0043] like Figure 1 As shown, a shaft cover 11 is embedded on the side 202 of the wheel, through which the wheel shaft 501 passes. The wheel shaft 501 and the shaft cover 11 are movably connected by a ball bearing 12.
[0044] like Figure 2 and Figure 3 As shown, four vertical guide column assemblies 8 are symmetrically arranged on the base 2 to provide stable support for the lifting and lowering of the V-shaped platform 1.
[0045] In this embodiment, the guide post assembly 8 includes a T-shaped guide sleeve 801 vertically embedded in the base 2. The T-shaped guide sleeve 801 can penetrate the cavity 201 and movably sleeve the guide post 802. The top of the guide post 802 is fixedly connected to the bottom surface of the V-shaped platform 1.
[0046] When the lifting cylinder 3 drives the V-shaped platform 1 to rise and fall, the four guide columns 802 can rise and fall synchronously, thereby ensuring that the V-shaped platform 1 can always rise and fall smoothly relative to the machine base 2, so as to better support the steel coil and effectively prevent the V-shaped platform 1 from tilting.
[0047] like Figure 2 As shown, the V-shaped platform 1 in this embodiment includes a platform frame 101 and a V-shaped support plate 103 disposed on the top of the platform frame 101. The platform frame 101 and the V-shaped support plate 103 are connected to each other to form a platform cavity 102.
[0048] In addition, the platform cavity 102 is provided with a number of vertical V-shaped ribs 104 for longitudinal support of the V-shaped support plate 103, so that it can better bear the weight of the steel coil.
[0049] As a further optimization of the V-shaped support plate described in this embodiment, the included angle of the V-shaped support plate 103 is 100° to 145°, which can better clamp the cylindrical steel coil. The larger the included angle, the larger the outer diameter of the steel coil it can support.
[0050] The above description is only for illustrating the embodiments of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
