Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for cold-rolled strip steel production in the metallurgical industry, and in particular to an auxiliary device for loading and unloading the sleeve of a cold-rolled strip steel coiler. Background Technology

[0002] In the continuous production of cold-rolled strip steel, in order to ensure the quality of the core of the finished steel coil, a rubber sleeve is installed on the mandrel of the coiler. The inner diameter of the rubber sleeve is smaller than the outer diameter of the mandrel to ensure the tightness of the rubber sleeve on the mandrel. Therefore, the installation or removal of the rubber sleeve usually requires manual loading and unloading, resulting in low efficiency and safety. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an auxiliary device for loading and unloading the sleeve of a cold-rolled strip steel coiler, which can avoid manual loading and unloading, and has high assembly and disassembly efficiency and is easy to implement safely.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides an auxiliary device for loading and unloading the sleeve of a cold-rolled strip steel coiler, including a liftable and laterally movable steel coil trolley, a saddle seat disposed on the steel coil trolley, and two side-push assemblies; the saddle seat is used to support the sleeve of the coiler, and the side-push assemblies include liftable movable seats, with the movable seats of the two side-push assemblies respectively disposed on both axial sides of the saddle seat; when the steel coil trolley drives the sleeve on the saddle seat to be fitted onto the mandrel of the coiler, the movable seats are raised, and only with the lateral movement of the steel coil trolley, one of the movable seats is laterally abutted against the corresponding side end face of the sleeve on the saddle seat, pushing or pushing the sleeve on the saddle seat out of the mandrel.

[0006] Furthermore, the side-pushing assembly includes a first driver, a fixed base, a guide rod, and a limiting member. The fixed base is assembled at one end of the steel coil trolley. The guide rod is movably inserted through the fixed base. The end of the guide rod protruding from the fixed base is equipped with the movable base. The limiting member is sleeved on the guide rod, and the limiting member is used to abut against the end of the fixed base opposite to the movable base. The first driver drives the end of the guide rod opposite to the movable base to drive the guide rod to rise on the fixed base.

[0007] Furthermore, the side-push assembly includes a spring, which is movably sleeved on the guide rod and disposed between the movable seat and the fixed seat.

[0008] Furthermore, the limiting component is a limiting nut.

[0009] Furthermore, in its natural state, the top surface of the movable seat is higher than the top surface of the saddle; in its compressed state, the top surface of the movable seat is lower than the top surface of the saddle.

[0010] Furthermore, it also includes a second driver and a third driver, which respectively drive the steel coil trolley to raise, lower, and traverse the steel coil trolley.

[0011] The technical solution provided by this utility model has the following beneficial effects:

[0012] 1. When it is necessary to install the sleeve, the sleeve is hoisted onto the saddle of the coil trolley, and then the saddle is raised to ensure that the center line of the sleeve coincides with the center line of the mandrel of the coiler. Then, the coil trolley moves laterally toward the mandrel of the coiler, simultaneously driving the sleeve on the saddle to be fitted onto the mandrel. Only with the lateral movement of the coil trolley, one of the movable seats on one side is raised and laterally abuts against the corresponding side end face of the sleeve on the saddle, so as to push the sleeve on the saddle to the center line position of the mandrel.

[0013] 2. When it is necessary to disassemble the sleeve, the coil trolley moves laterally toward the mandrel away from the coiler, and only with the lateral movement of the coil trolley, the movable seat on one side is raised and laterally abuts against the corresponding side end face of the sleeve on the saddle, so as to push or push the sleeve off the mandrel.

[0014] 3. This utility model can avoid manual loading and unloading, and has high assembly and disassembly efficiency and is easy to implement safely. Attached Figure Description

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 3 This embodiment provides a loading and unloading auxiliary device for the sleeve of a cold-rolled strip steel coiler (hereinafter referred to as the loading and unloading auxiliary device), including a lifting and horizontally movable steel coil trolley 300, a saddle 200 and two side push components 100 disposed on the steel coil trolley 300, wherein the saddle 200 is used to support the sleeve 400 of the coiler, and the side push components 100 are used to push the sleeve 400 on the mandrel 500 of the coiler.

[0021] like Figure 1 and Figure 3 As shown, each side push assembly 100 includes a first driver, a fixed seat 2, two guide rods 4, two limiting members 3, two springs 5, and a liftable movable seat 1. The first driver is a lifting hydraulic cylinder, and the movable seats 1 of the two side push assemblies 100 are respectively arranged on both axial sides of the saddle 200.

[0022] More specifically, the fixed seats 2 of the two side-push components 100 are respectively assembled at both ends of the steel coil trolley 300. Each guide rod 4 is movably inserted through its corresponding fixed seat 2. The two guide rods 4 in the same group protrude from the upper end of the fixed seat 2 and are each assembled to a movable seat 1 in the same group. Each guide rod 4 is fitted with a limiting member 3, and the limiting member 3 is used to abut 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 fitted through its corresponding guide rod 4 and is respectively arranged between the movable seat 1 and the fixed seat 2.

[0023] Furthermore, the loading and unloading auxiliary device in this embodiment also includes a second driver and a third driver. Specifically, the second driver is a lifting hydraulic cylinder, and the third driver is a transverse motor drive unit. Therefore, the second driver and the third driver respectively drive the connected steel coil trolley 300 to drive the steel coil trolley 300 to lift, lower, and transverse.

[0024] In specific implementation, the limiting component 3 is a limiting nut. In the natural state where the spring 5 is not subjected to external force, the top surface of the movable seat 1 is higher than the top surface of the saddle 200. In the compressed state where the spring 5 is subjected to pressure, the top surface of the movable seat 1 is lower than the top surface of the saddle 200. In this way, in the abnormal situation where 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 retract on its own with the cooperation of the spring 5, so that the top surface (i.e., the upper surface) of the movable seat 1 and the saddle 200 are flush, thereby preventing the steel coil from overturning.

[0025] like Figure 1 As 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 present 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 present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
