[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0024] This application discloses a protective cover for overhead cranes used in cleanrooms. (Refer to...) Figure 1 , Figure 2 and Figure 3 A protective cover for overhead cranes used in cleanrooms includes a guide rail 1, an overhead crane body 3 mounted on the surface of the guide rail 1, and a protective mechanism 2 mounted on the surface of the overhead crane body 3.
[0025] The protective mechanism 2 includes a protective cover body 201. The inner cavity of the protective cover body 201 is movably connected to the surface of the overhead crane body 3. The top and bottom of the inner cavity of the protective cover body 201 are provided with fixing slots 204. The inner cavity of the fixing slots 204 is fitted with fixing blocks 203. One side of the fixing blocks 203 is fixedly connected to the surface of the protective cover body 201.
[0026] Reference Figure 2 and Figure 3The protective cover body 201 has positioning grooves 205 at each of its four corners. Positioning rods 202 are movably connected to the inner cavity of the positioning grooves 205. One side of the positioning rods 202 is fixedly connected to the surface of the protective cover body 201. The positioning rods 202 guide the protective cover body 201 and prevent the protective cover body 201 from shifting its position during the closing process. This would prevent the fixing block 203 from being stably engaged into the fixing groove 204, thus affecting the protective effect on the surface of the overhead crane body 3.
[0027] Reference Figure 1 , Figure 2 and Figure 4 A fan 5 is installed on the top of the front side of the protective cover body 201. A filter mechanism 4 is connected to the bottom of the fan 5. The filter mechanism 4 is installed at the bottom of the front side of the protective cover body 201. The fan 5 can clean the dust attached to the surface of the overhead crane body 3, prevent the overhead crane body 3 from being contaminated, and reduce the service life of the overhead crane body 3.
[0028] Reference Figure 4 The filtration mechanism 4 includes a filter box 401. The back side of the filter box 401 is fixedly connected to the front side of the protective cover body 201. The inner cavity of the filter box 401 is provided with a filter groove 411. The right side of the inner cavity of the filter groove 411 is provided with a movable groove 402. The inner cavity of the movable groove 402 is movably connected to a movable plate 408. The inner cavity of the movable plate 408 is respectively equipped with a first filter screen 404 and a second filter screen 405. Through the setting of the filter box 401, the dust drawn out by the fan 5 can be collected to prevent the dust from falling onto the surface of the product. At the same time, through the setting of the first filter screen 404 and the second filter screen 405, the dust in the air is filtered and intercepted.
[0029] Reference Figure 4 The first filter 404 is positioned above the second filter 405. The first filter 404 is made of polyester nonwoven fabric, and the second filter 405 is made of activated carbon. The first filter 404 is used to filter large particles of dust and impurities in the air, while the second filter 405 is used to adsorb the fine particles filtered by the first filter 404, thus preventing dust from escaping from the inside of the filter box 401.
[0030] Reference Figure 4 A fixing groove 403 is provided on the right side of the inner cavity of the movable groove 402. A fixing plate 406 is snapped into the inner cavity of the fixing groove 403. The left side of the fixing plate 406 is fixedly connected to the right side of the movable plate 408. A handle 407 is fixedly connected to the right side of the fixing plate 406. By setting the fixing groove 403, the fixing plate 406 can be snapped into the interior of the filter box 401, thereby fixing the position of the movable plate 408 and making the movable plate 408 stably fixed inside the filter box 401.
[0031] Reference Figure 4 and Figure 5 A support groove 410 is provided on the left side of the inner cavity of the filter box 401. A support rod 409 is inserted into the inner cavity of the support groove 410. The right side of the support rod 409 is fixedly connected to the left side of the movable plate 408. The support rod 409 provides support for the position of the movable plate 408, improves the stability of the movable plate 408, and prevents the movable plate 408 from shifting its position during use.
[0032] Working principle: First, by pushing the two protective cover bodies 201 inward, the inner sides of the protective cover bodies 201 are closed together. During the movement of the protective cover bodies 201, the positioning rod 202 and the fixing block 203 move synchronously. The positioning rod 202 inserts into the positioning groove 205 to guide the movement of the protective cover body 201 and prevent the position of the protective cover body 201 from shifting during the closing process. This would prevent the fixing block 203 from being stably engaged in the fixing groove 204, affecting the protective effect on the surface of the overhead crane body 3. The fixing block 203 engages in the fixing groove 204 to secure the protective cover body 201. The protective cover body 201 is fixed in position so that it can be stably fixed on the surface of the overhead crane body 3 for protection, thereby reducing dust contamination of the product. After the protective cover body 201 is closed, the dust on the surface of the overhead crane body 3 is cleaned and extracted by the fan 5 and transported to the inside of the filter box 401 by the fan 5. After entering the filter box 401, it will be filtered twice by the first filter screen 404 and the second filter screen 405. The first filter screen 404 filters out large dust and impurities in the air, and the second filter screen 405 adsorbs the fine particles filtered by the first filter screen 404, thereby preventing dust from falling out of the filter box 401 and reducing the possibility of product contamination.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
