[0039] The present application will be described below with reference to the drawings:

[0040] Figure 1 The structure of the telescopic platform in some embodiments or certain embodiments of the present application is shown, with reference to Figure 1 It can be seen that the embodiments of the present application provide a telescopic platform for crossing the opening 200 between the platforms on both sides of the shuttle vehicle 100, and the platforms on both sides of the shuttle vehicle 100 are respectively the first platform 300 and the second platform 400. The telescopic platform comprises:

[0041] The telescopic cylinder 1 is provided with a cylinder seat 11 fixed with the first platform 300, and a telescopic rod 12 reciprocatingly telescoped relative to the cylinder seat 11.

[0042] The support 2 is fixed to the first platform 300 and spaced from the telescopic rod 12.

[0043] The guide rod 3 is fixed at one end to the support 2 and has an axis extending along the axis of the telescopic rod 12.

[0044] The platform body 4 is fixedly connected to the telescopic rod 12 and configured to be driven by the telescopic rod 12 to straddle the opening 200, and the platform body 4 is slidably sleeved on the guide rod 3 along the axial direction of the guide rod 3.

[0045] When the operator needs to place the steel coil on the saddle 600 of the entry section or needs to perform routine maintenance on the equipment of the entry section, the platforms on both sides of the opening 200 of the entry section can be the first platform 300 and the second platform 400, respectively, and the telescopic cylinder 1 in the telescopic platform is provided with a cylinder seat 11 fixed to the first platform 300 and a telescopic rod 12 reciprocally telescoped relative to the cylinder seat 11 for providing power. The support 2 fixed to the first platform 300 and spaced from the telescopic rod 12 provides support for the guide rod 3, one end of the guide rod 3 is fixed to the support 2, and the axis of the guide rod 3 extends along the axis of the telescopic rod 12, and the platform body 4 fixedly connected to the telescopic rod 12 is slidably sleeved on the guide rod 3 along the axial direction of the guide rod 3. When driven by the telescopic rod 12 in the telescopic cylinder 1, the guide rod 3 can guide the telescopic cylinder 1, so that the platform body 4 can be stably moved. The platform body 4 can be driven by the telescopic rod 12 of the telescopic cylinder 1 on the first platform 300 to straddle the opening 200, so that the platform body 4 can straddle the opening 200 to provide support. When adjusting the steel coil or maintaining the equipment, the operator can stand on the platform body 4, reducing the risk of falling or falling into the opening 200, improving the safety of the operator during the production of the steel coil and the maintenance of the equipment, and to some extent solving the technical problem that the safety during the production of the steel coil and the maintenance of the equipment is not ideal.

[0046] It should be noted that during the process of adjusting the position of the steel coil on the saddle 600 or maintaining the routine equipment, the operator may need to straddle the opening 200 and support on the first platform 300 and the second platform 400, respectively. In this state, adjusting the position of the steel coil and maintaining the routine equipment may have certain risks, therefore, increasing the platform body 4 that can be driven by the telescopic rod 12 of the telescopic cylinder 1 to straddle the opening 200, so that the operator can stably stand on the platform body 4 to operate, reducing the possibility of the operator falling or falling into the opening 200, and improving the safety of the operator during the process of adjusting the position of the steel coil and maintaining the routine equipment.

[0047] In some or certain embodiments, the platform body 4 is fixedly connected to the telescopic rod 12 and supported on the first platform 300, and the working stroke of the telescopic rod 12 is greater than the width of the opening 200.

[0048] The platform body 4 is fixedly connected with the telescopic rod 12 and supported on the first platform 300. The working stroke of the telescopic rod 12 is greater than the width of the opening 200. Therefore, in the telescopic working stroke of the telescopic rod 12, the telescopic rod 12 can drive the moving distance of the platform body 4 fixedly connected therewith to be greater than the width of the opening 200 between the first platform 300 and the second platform 400. It is easier to realize that the platform body 4 is driven by the telescopic rod 12 to cross the first platform 300 and the second platform 400. When the telescopic rod 12 is retracted, the platform body 4 can also be supported as a whole on the first platform 300, reducing the interference between the platform body 4 and the shuttle vehicle 100 at the opening 200, and also being beneficial to improve the safety of the operation of the shuttle vehicle 100.

[0049] In some or certain embodiments, the end of the telescopic rod 12 away from the cylinder seat 11 is towards the opening 200, the platform body 4 is in a cuboid shape, and the width of the platform body 4 is greater than the width of the opening 200.

[0050] The end of the telescopic rod 12 away from the cylinder seat 11 is towards the opening 200, so that the telescopic rod 12 can be close to or away from the opening 200 when telescoping, so that the platform body 4 fixedly connected with the telescopic rod 12 is close to or away from the opening 200. The platform body 4 is in a cuboid shape, the width of the platform body 4 is greater than the width of the opening 200, which can also facilitate the platform body 4 to cross the opening 200, and the two sides of the platform body 4 can be supported on the first platform 300 and the second platform 400 respectively.

[0051] In some or certain embodiments, the opening 200 at the inlet section can be in a strip shape, and there is an included angle between the length direction and the axial direction of the telescopic rod 12. The length of the cuboid-shaped platform body 4 can extend along the length direction of the opening 200, the width direction of the platform body 4 can extend along the width direction of the opening 200, and the platform body 4 can be supported on the first platform 300. When the telescopic rod 12 telescopes, it is convenient to drive the platform body 4 to move to cross the opening 200, and the two sides of the platform body 4 in the width direction can be supported on the first platform 300 and the second platform 400 respectively. It should be noted that during the driving process of the platform body 4 by the telescopic rod 12, the platform body 4 always has a part supported on the first platform 300. When the telescopic rod 12 is retracted to the maximum amplitude into the cylinder seat 11, the first platform 300 can be supported as a whole on the first platform 300.

[0052] In some or certain embodiments, the axis of the telescopic rod 12 and the opening 200 can have an included angle, and the platform body 4 can also be provided in a disc shape or an irregular plate shape, etc. It can also be pushed by the telescopic rod 12 to cross the opening 200, which can improve the safety of the operator during the operation process.

[0056] In some or certain embodiments, at least two wear-resistant sleeves 5 can be arranged along the circumference of the guide hole 41, and the axial positioning between the wear-resistant sleeve 5 and the platform body 4 can be achieved by arranging fasteners (bolts, screws, etc.) inserted into the platform body 4 at both ends of the wear-resistant sleeve 5, and the fasteners at both ends can be used to tightly press the two ends of the wear-resistant sleeve 5, and the wear-resistant sleeve 5 can be a graphite copper sleeve. This is conducive to prolonging the service life of the platform body 4 and facilitating the stable movement between the platform body 4 and the guide hole 41.
