[0004] The utility model discloses a car roof wheel protection device which overcomes the above-mentioned deficiencies in the prior art.

[0005] Further, the lower protection device comprises a side plate and a bottom plate, the side plate is arranged adjacent to the side edge of the car roof wheel and is provided with an opening avoiding the rotating shaft, the side plate is fixed to the bottom of the car upper beam, the bottom of the side plate is transversely fixed with the bottom plate, and the bottom plate is arranged adjacent to the bottom edge of the car roof wheel. The side plate and the bottom plate mainly shield the lower half of the car roof wheel, form a complete surrounding structure, have good protection effect, have large shielding surface, and do not affect the normal operation of the car roof wheel.

[0006] Further, the side plate and the bottom plate are fixedly connected through screws at adjacent edges, and a reinforcing rib is further fixedly arranged on the bottom plate and is arranged in the length direction of the bottom plate. The bottom and the side can be opened separately, facilitating maintenance at the corresponding position, and the structure is stable and not easy to shake.

[0007] Further, the side plate and the bottom plate are integrally bent into a "N" type structure from a plate material. A relatively simple structure can also be provided, and when the elevator specifications are small and the wheel diameter of the car top wheel is small, the simple protective structure can be used.

[0008] Further, the upper protective device includes a flat plate, the side edges of the flat plate are installed through fixing screws on the upper beam of the car frame, and the screw holes for the fixing screws are gourd holes. The flat plate is convenient to install, the gourd hole can clamp the screw, and the problem of screw falling during disassembly and maintenance is avoided. The screw holes of the lower protective device can also be gourd holes.

[0009] Compared with the prior art, the present application has the following advantages and effects: the design is a protective structure improvement of the car top wheel, which can be combined with the basic part of the car frame structure, improve the overall protection area, and is convenient for maintenance and improves the work efficiency of daily maintenance and maintenance. The overall structure is lightweight, and the manufacturing and use difficulty is low. BRIEF DESCRIPTION OF DRAWINGS
