Description

Technical Field

[0001] This utility model relates to the technical field of airflow machine cover plates, specifically a fireproof cover plate for an airflow machine. Background Technology

[0002] The underbody cover of the Rieter R923 and R35 airflow locomotive consists of a flammable plastic sheet and wheel hubs, located at the bottom of the locomotive section. It is supported by the wheel hubs and hung on fixed columns on the locomotive body. The wheel hubs have grooves, and each section has a supporting crossbeam at the bottom, with the cover's wheel hub support points at both ends. During operation, the locomotive body contains rotating guide wheels, a running conveyor belt, and an electrical control panel. Below the cover is a raw material (cotton swab) storage area. The purpose of the cover is to prevent cotton, oil, and dirt from falling into the raw material bins and contaminating the materials.

[0003] However, a search revealed that the existing technology for the floor cover of Rieter R923 and R35 airflow locomotives uses a flammable plastic material with an ignition point of 75 degrees Celsius. It is highly flammable when exposed to a spark, and if the spark falls into the raw materials below, it can cause a larger fire, posing a fire hazard. Furthermore, it ages quickly, becomes fragile, and loses its effectiveness, allowing contaminants to fall into the raw material barrels and contaminate the raw materials, affecting their quality. Therefore, it is essential to design a fireproof cover for the airflow locomotive to solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fireproof cover for airflow locomotives. It solves the problem that the existing floor cover used for Rieter R923 and R35 airflow locomotives is made of a flammable plastic material with an ignition point of 75 degrees Celsius. This material is highly flammable and easily ignites upon contact with a source of fire. If the ignition source falls into the raw materials below, it can cause a larger fire, posing a fire hazard. Furthermore, the material ages quickly, becomes fragile, and loses its effectiveness, allowing contaminants to fall into the raw material drums and contaminate the raw materials, affecting their quality.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fireproof cover plate for an airflow machine, comprising a cover plate body, wherein each of the two pairs of slots of the cover plate body is fitted with a locking block, and a long wheel hub is fixedly connected to the top of the locking block, and the outer wall of the long wheel hub is in contact with the top of the cover plate body, and a limiting mechanism and a fixing mechanism are installed on the outer wall of the long wheel hub.

[0006] Preferably, the limiting mechanism includes two pairs of vertical plates disposed at the top of the cover plate body, a pair of arc-shaped blocks are fixed to the outer wall of the vertical plates, and an L-shaped baffle is hinged between adjacent arc-shaped blocks by a pin, and the end of the L-shaped baffle away from the arc-shaped block is engaged with the slot of the long wheel hub.

[0007] Preferably, the fixing mechanism includes a pair of horizontal plates fixedly connected to the vertical plate, a screw is rotatably connected to the adjacent horizontal plates, a rectangular sleeve is threaded to the lower outer wall of the screw, a slider is fixedly connected to the front end face of the rectangular sleeve, and the slider is slidably engaged with the groove of the L-shaped baffle.

[0008] Preferably, a first handle is fixed to the top end of the screw.

[0009] Preferably, a rectangular block is fixed to the end of the vertical plate away from the elongated wheel hub, and the rectangular block is threadedly connected to the cover plate body by bolts.

[0010] Preferably, a second handle is fixedly connected to the middle of the top of the cover plate body, and a rubber sleeve is fitted onto the outer wall of the second handle.

[0011] Beneficial effects

[0012] This utility model provides a fireproof cover for an airflow machine, which has the following beneficial effects:

[0013] The long hub can be used to move the locking block, allowing it to align with the top of the cover plate body. This causes the locking block to engage with the slot in the cover plate body. Then, the vertical plate moves, causing it to move a rectangular block that aligns with the top of the cover plate body. The rectangular block is then secured to the cover plate body with bolts. Turning the first handle rotates the screw at the horizontal plate, causing it to move the slider via the rectangular sleeve. The slider then rotates the L-shaped baffle at the arc-shaped block, causing one end of the L-shaped baffle to engage with the slot in the long hub. This connects and secures the long hub to the cover plate body. The second handle then moves the cover plate body and long hub, allowing it to be installed on the air locomotive. The cover plate body is made of fire-retardant PVC material, which is flame-retardant, resistant to weathering, and produces no debris. It is cost-effective, prevents fires, prevents foreign objects from entering raw materials, and reduces quality risks. Attached Figure Description
