Description

Technical Field

[0001] The utility model relates to the field of conveyor lines, in particular to a linkage type maintenance platform. Background Art

[0002] For large conveyor lines between warehouses, they generally have to pass through the fire shutter doors corresponding to the warehouses. However, due to the interference of the maintenance platform on the fire shutter doors, existing conveyor lines generally do not add maintenance platforms at the corresponding fire shutter doors to avoid the problem that the shutter doors cannot be closed in time when encountering fire hazards. However, this measure cannot reserve platform maintenance space for maintenance personnel when the conveyor belt line needs to be repaired, which makes maintenance inconvenient and also poses safety hazards during the maintenance process.

[0003] To this end, we propose a linkage maintenance platform to solve the above problems. Utility Model Content

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0020] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0021] like Figure 1 and 2 As shown, in this embodiment, for the overall structure, a linkage maintenance platform includes a telescopic belt conveyor, and the belt conveyor includes at least one end that can be telescopically docked with an external transport line, characterized in that: the maintenance platform includes a square platform plate 1 and a channel steel rail 2, and the channel steel rail 2 includes two and is relatively arranged, and its length corresponds to the length of the long end of the platform plate 1, and the two channel steels are provided with a slide 3 on their respective sides facing away, and the groove direction of the slide 3 is consistent with the telescopic direction of the external belt conveyor, and rollers 4 are fixed to the bottom of both sides of the long end of the platform plate 1, and each side of the bottom roller 4 includes a plurality of rollers and is equidistantly arranged in the groove direction of the slide 3, and each roller 4 is in rolling contact with the inner wall of the slide 3, and the platform plate 1 is also fixed with a connecting member 5 on one side of its short end, and is connected and fixed to the telescopic end of the external belt conveyor through the connecting member 5.

[0022] After being linked with one end of the external belt conveyor, the entire platform plate 1 can be driven to slide in the channel steel track 2 through the connecting piece 5. Correspondingly, since the groove direction of the slide 3 is consistent with the extension and contraction direction of the belt conveyor, when docking the logistics line between warehouses, it will not interfere with the closing of the fire shutter door. Subsequently, the external fire signal can be linked to realize the rapid recovery of the maintenance platform.

[0023] As for the positioning of the maintenance platform, due to the linkage effect of the connecting member 5, the telescopic end of the external belt conveyor is fixed when it is movable, and the position positioning of the maintenance platform can be realized synchronously accordingly.

[0024] As for the connection between the platform plate 1 and the telescopic end of the belt conveyor, the actual connection structure may include multiple types. In this embodiment, the connecting member 5 includes a first connecting plate 9 and a second connecting plate 10. The first connecting plate 9 is square and parallel to the outer edge surface of the hollow square steel 7. The first connecting plate 9 has a first connecting groove 11 and a second connecting groove 12 at both ends. The platform plate 1 is also fixed with a fixing plate 13 corresponding to the first connecting groove 11. A floating screw 15 is fixed on the fixing plate 13 through a fixing platform 14. The floating screw 15 passes through the first connecting groove 11 and can float up and down. A positioning groove 16 is provided at one end of the second connecting plate 10 and is positioned with the second connecting groove 12 bolts through the positioning groove 16. The other end is an integrally formed special-shaped plate 17. The special-shaped plate 17 has a connecting hole 18 on the side away from the platform plate 1, and is connected and fixed to the telescopic end of the external belt conveyor through the connecting hole 18.

[0025] The floating screw 15 is located at the center of the first connecting slot 11 and has a vertical floating distance of no less than 2 mm. The channel steel wall thickness does not exceed the floating distance setting for the floating screw 15. Specifically, in this embodiment, the floating screw 15 has a diameter of 16 mm, corresponding to the 18 mm width of the first connecting slot 11. This allows for a floating space of 1 mm in both directions, and the corresponding channel steel wall thickness is less than 2 mm, ensuring that the roller 4 at the bottom of the subsequent platform can enter and exit the end of the slide slot 3.

[0026] like Figure 2 As shown, in this embodiment, a support frame 6 is also fixed around the bottom of the platform plate 1. The support frame 6 is composed of multiple hollow square steels 7 welded adjacent to each other. The length of the hollow square steels 7 corresponds to the peripheral length of the platform plate 1, and the outer edge of the hollow square steels 7 is flush with the side surface of the platform plate 1. Integral reinforcement steel 8 is also welded to the hollow square steels 7.

[0027] The movable platform formed by welding a plurality of hollow square steels 7 and reinforcing steels 8 can better provide support for the platform plate 1 and provide protection for the subsequent operators to stand.

[0028] Furthermore, the second connecting groove 12 is transverse and includes two strips. The second connecting piece 10 is arranged at an angle, and the positioning groove 16 is provided overlying the second connecting groove 12. The positioning groove 16 and the second connecting groove 12 have the same width. Similarly, this solution also has a handrail 19 fixed to one side of the top of the platform plate 1. This provides a safer and more convenient support for subsequent maintenance personnel.

[0029] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
