[0025] Please see Figure 1-7 This utility model provides a technical solution: a clean monorail gantry crane, including a main track beam 1, a hanger 2, an electric hoist protective cover 3, a hook protective cover 4, and a track protective cover 5. The hanger 2 is symmetrically arranged above the main track beam 1. Baffles 101 are provided at both ends of the main track beam 1, and an electric hoist body is provided on the main track beam 1. The electric hoist protective cover 3 is fitted on the electric hoist body, and the hook protective cover 4 is fitted on the hook of the electric hoist body. The track protective cover 5 is fixed on both sides of the electric hoist protective cover 3 and is fitted on the main track beam 1. A cylindrical roller 502 is provided on the inner side of the track protective cover 5. By setting the track protective cover 5 to be fixed on both sides of the electric hoist protective cover, the track protective cover 5 is stretched and compressed during the horizontal movement of the electric hoist. The track protective cover 5, the electric hoist protective cover 3, and the hook protective cover 4 are used to protect the track body, the electric hoist body, and the hook, respectively. The track protective cover 5 can also collect dust.
[0026] Furthermore, the main track beam 1 is made of H-beam steel, and the cylindrical roller 502 contacts the lower flange of the main track beam 1 to ensure that the track protective cover 5 slides on the main track beam 1 when stretched or compressed.
[0027] Furthermore, a first mounting plate 401 is provided above the lower hook protective cover 4, and the first mounting plate 401 is connected to the electric hoist protective cover 3. A sealing plate with an internal opening is provided below the lower hook protective cover 4 to expose the hook of the electric hoist body.
[0028] Furthermore, baffles 101 are welded to both ends of the main track beam 1, and a second mounting plate 501 is provided at the end of the track protective cover 5. The second mounting plate 501 is connected to the baffles 101 to prevent the track protective cover 5 from sliding off the main track beam 1.
[0029] Furthermore, both the lower hook protective cover 4 and the track protective cover 5 are made of PVC accordion covers, and the length compression ratio is 1:10 based on the width of the pleats. The electric hoist protective cover 3 is made of SUS304 stainless steel, which improves the protection effect.
[0030] Furthermore, a connecting plate 201 is welded below the hanger 2, a fixing plate 202 is welded above the hanger 2, and a clamping plate 2011 is fixed below the connecting plate 201. The clamping plate 2011 is clamped on the upper wing plate of the main track beam 1 and can be adjusted left and right to facilitate the left and right positioning of the hanger 2 and the main track beam 1. The fixing plate 202 is used to fix the device.
[0031] In summary, when this device is in use, the electric hoist moves horizontally along the main track beam 1. During this process, the track protective covers 5 on both sides of the electric hoist protective cover 3 are stretched and compressed. Furthermore, dust generated by friction during the movement of the electric hoist body falls into the track protective covers 5, effectively collecting the dust and preventing dust from falling onto the main track beam 1. Moreover, during operation, the electric hoist protective cover 3, the lower hook protective cover 4, and the track protective cover 5 maximize protection of the workpiece from dust contamination, providing a clean working environment for hoisting workpieces in cleanrooms.
[0032] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
