[0018] To further illustrate the embodiments, the present application provides drawings. These drawings are part of the disclosure of the present application, and mainly serve to illustrate the embodiments, and can be used to explain the operating principle of the embodiments in conjunction with the related description of the specification. Those skilled in the art should be able to understand other possible implementations and advantages of the present application by referring to these contents. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The application will be further described in conjunction with the drawings and specific embodiments.

[0020] With reference to Figures 1 to 3 , the embodiment provides a coil unloading and loading auxiliary device of a cold-rolled strip steel coiler (hereinafter referred to as the unloading and loading auxiliary device), which comprises a steel coil trolley 300 that can be lifted and horizontally moved, a saddle 200 arranged on the steel coil trolley 300, and two side pushing assemblies 100, wherein the saddle 200 is used for supporting a sleeve 400 of the coiler, and the side pushing assemblies 100 are used for pushing the sleeve 400 on a mandrel 500 of the coiler.

[0021] As shown in Figure 1 and Figure 3 , each side pushing assembly 100 comprises a first driver, a fixed seat 2, two guide rods 4, two limit pieces 3, two springs 5, and a movable seat 1 that can be lifted, wherein the first driver is a lifting hydraulic cylinder, and the movable seats 1 of the two side pushing assemblies 100 are respectively arranged on the two axial sides of the saddle 200.

[0022] In particular, the fixed seats 2 of the two side pushing assemblies 100 are respectively assembled at the two ends of the steel coil trolley 300, each guide rod 4 is movably arranged in the corresponding fixed seat 2, the two guide rods 4 in the same group protruding from the upper end of the fixed seat 2 are assembled in the same group of movable seats 1, each guide rod 4 is sleeved with a limit piece 3, and the limit piece 3 is used for abutting against the lower end of the corresponding fixed seat 2 away from the movable seat 1, so as to limit the lifting height of the guide rod 4 and the movable seat 1. At the same time, each spring 5 is movably sleeved on the corresponding guide rod 4 and arranged between the movable seat 1 and the fixed seat 2.

[0023] In addition, the unloading and loading auxiliary device of the embodiment further comprises a second driver and a third driver, in particular, the second driver is a lifting hydraulic cylinder, and in particular, the third driver is a horizontal moving motor driving unit, therefore, the second driver and the third driver are respectively drivingly connected with the steel coil trolley 300, so as to drive the steel coil trolley 300 to lift, descend and horizontally move.

[0024] In specific implementation, the limit piece 3 is a limit nut, in the natural state of the spring 5 without external force, the top surface of the movable seat 1 is higher than the top surface of the saddle 200, and in the compressed state of the spring 5 under pressure, the top surface of the movable seat 1 is lower than the top surface of the saddle 200, so that in the abnormal case that the center of the steel coil and the center of the saddle 200 are not aligned with each other, after the steel coil is pressed on the movable seat 1, the movable seat 1 can be automatically retracted under the cooperation of the spring 5, so that the top surfaces (i.e. upper surfaces) of the movable seat 1 and the saddle 200 are flush, thereby avoiding the steel coil from being turned over.

[0025] As shown in Figure 1As shown, when the sleeve 400 needs to be installed, the sleeve 400 is hoisted onto the saddle 200 of the coil trolley 300. Then, the saddle 200 is raised by the second drive to ensure that the center line of the sleeve coincides with the center line of the mandrel of the coiler. Afterward, the third drive drives the coil trolley 300 to move laterally towards the mandrel 500, simultaneously moving the saddle 200 and the sleeve 400 laterally, and placing the sleeve 400 onto the mandrel 500. Due to the inner... The outer diameter of the sleeve 400 is smaller than that of the mandrel 500. Therefore, during the movement of the saddle 200, the sleeve 400 and the mandrel 500 stop moving due to friction. However, the first driver drives the movable seat 1 on one side to rise. Then, only under the lateral movement of the steel coil carriage 300, the sleeve 400 is laterally pressed against the corresponding side end face of the sleeve 400 on the saddle 200 to push the sleeve 400 on the saddle 200 to the center line position of the mandrel 500, thus completing the installation of the sleeve 400.

[0026] like Figure 2 As shown, when it is necessary to disassemble the sleeve 400, the coil trolley 300 moves laterally away from the mandrel 500, and only with the lateral movement of the coil trolley 300, the movable seat 1 on one side is raised and laterally abuts against the corresponding side end face of the sleeve 400 on the saddle 200, so as to push or push the sleeve 400 off the mandrel 500, thus completing the disassembly of the sleeve 400.

[0027] In summary, the loading and unloading auxiliary device of this embodiment can avoid manual loading and unloading, and has high assembly and disassembly efficiency and is easy to implement safely.

[0028] Of course, in other embodiments, the limiting member 3 and the spring 5 are optional accessories.

[0029] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
