[0002] For general elevators, the car top wheel is connected with the upper beam device, and the periphery of the car top wheel is simply bent into a dustproof cover with a steel plate to prevent dust, which has little effect on reducing noise. However, when the elevator speed is relatively high (v≥ 2.5m / s) Due to the high speed, the friction between the car top wheel and the wire rope and the vibration of the car top wheel itself will produce huge noise. If there is no noise reduction equipment, passengers will obviously feel the noise in the car, so it is urgently needed A soundproof dust cover capable of both dustproof and soundproof

Embodiment Construction
[0010] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:
[0011] according to figure 1 and figure 2 A sound-insulating dust cover shown is installed on the upper beam 1 of the car. The sound-insulating dust cover is composed of an upper dust cover 2 and a lower dust cover 3. The upper dust cover 2 and the lower The dust cover 3 is bent, and the lower dust cover 3 is composed of the lower bottom plate 4 bent multiple times and the lower side plates 5 fixedly connected to both sides of the lower bottom plate 4 , the bottom edge of the lower bottom plate 4 A plurality of threaded holes 6 are provided, and the upper dust cover 2 is composed of a U-shaped upper base plate 7 bent multiple times and a connecting frame 8 fixedly connected to both sides of the upper base plate 7, and the connecting frame 8 is composed of an L-shaped A U-shaped left side plate 9 and a U-shaped right side plate 10 are fixedly connecte...

The invention relates to a soundproof dust cover which is arranged on a car cross-head. The soundproof dust cover consists of an upper dust cover and a lower dust cover; the upper dust cover and the lower dust cover are formed by bending; the lower dust cover consists of a lower bottom plate which is bent repeatedly and lower lateral plates fixedly connected to both sides of the lower bottom plate; the bottom edge of the lower bottom plate is provided with a plurality of screw thread holes; the upper dust cover consists of an upper bottom plate which is bent repeatedly and is of a U shape and connecting frames fixedly connected to both sides of the upper bottom plate; each connecting frame is formed by fixedly connecting a left lateral plate and a U-shaped right lateral plate; the left lateral plate is of an L shape; the L-shaped side of the connecting frame is provided with a plurality of screw thread holes. The soundproof dust cover has the beneficial effects that by designing the novel structure, the soundproof dust cover takes effect of not only preventing dust, but also insulating sound.
Description
Technical field: [0001] The invention relates to a sound-insulating dust cover, which belongs to the technical field of elevators. Background technique: [0002] For general elevators, the car top wheel is connected with the upper beam device, and the periphery of the car top wheel is simply bent into a dustproof cover with a steel plate to prevent dust, which has little effect on reducing noise. However, when the elevator speed is relatively high (v≥ 2.5m / s) Due to the high speed, the friction between the car top wheel and the wire rope and the vibration of the car top wheel itself will produce huge noise. If there is no noise reduction equipment, passengers will obviously feel the noise in the car, so it is urgently needed The utility model relates to a sound-insulating dust cover capable of both preventing dust and sound-insulating. Invention content: [0003] The technical problem to be solved by the present invention is to provide a soundproof dust cover capable of b...
