[0034] As described in the background art, the belt conveyor protective cover is a device used to protect the belt conveyor. It can prevent material splashing, protect the safety of operators, and reduce environmental pollution. There are three types of upper protective covers for existing belt conveyors, including a completely fixed belt protective cover, a movable protective cover, and an open-type protective cover. Among them, generally seven completely fixed belt protective covers are continuously installed during installation, and the edges of adjacent protective covers overlap and lap. A position for a movable protective cover is reserved behind. One side of the movable protective cover is fixed with a hinge, and the other side is fixed with a buckle. When it needs to be opened for use, loosen the buckle on one side, lift the protective cover, and open it 180° around the hinge, so as to facilitate the inspection and maintenance of the idler, support, and belt by the belt inspection personnel. At the same time, it is convenient for the sanitation personnel to collect the spilled materials. The fixed open-type protective cover is based on the fixed protective cover, and movable windows are opened on both sides of the fixed protective cover. By opening the movable windows, the belt conveyor can be inspected and the spilled materials can be collected. However, when performing belt maintenance on the existing belt conveyor, it is necessary to remove the upper fixed protective cover and the movable protective cover. Most of the fixed protective cover and the movable protective cover are made of polyurethane materials, and frequent disassembly and assembly are likely to cause deformation and tearing damage.

[0035] See Figures 1 to 7As shown in the figure, to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a protective cover device. The protective cover device is used to protect the maintenance area on the belt conveyor equipment. The protective cover device includes: a track part 10 and a protective cover part 20. The track part 10 includes a first track section 11 and a second track section 12. The second track section 12 is higher than the first track section 11. The position of the first track section 11 corresponds to the position of the maintenance area. The protective cover part 20 is movably installed on the track part 10 along the extending direction of the track part 10. The protective cover part 20 has a protective state located on the first track section 11 and protecting the maintenance area, and a maintenance state located on the second track section 12 and avoiding the maintenance area. The protective cover device provided in this embodiment sets the track part 10 to include the first track section 11 and the second track section 12, and sets the second track section 12 to be higher than the first track section 11, so that the protective cover part 20 movably installed on the track part 10 along the extending direction of the track part 10 can be switched between the first track section 11 and the second track section 12. When it is necessary to protect the maintenance area on the belt conveyor equipment, since the position of the first track section 11 corresponds to the position of the maintenance area, the protective cover device provided in this embodiment can protect the maintenance area by setting the protective cover part 20 on the first track section 11. When it is necessary to perform maintenance on the maintenance area of the belt conveyor equipment, the protective cover device provided in this embodiment can avoid the maintenance area by setting the protective cover part 20 on the second track section 12, thus facilitating the user to perform maintenance on the maintenance area of the belt conveyor equipment. At the same time, when there is a fixed protective cover on the belt conveyor equipment, the protective cover part 20 in the protective state can overlap with the fixed protective cover to provide sufficient protection for the belt conveyor equipment. Since the second track section 12 is higher than the first track section 11, the protective cover part 20 in the maintenance state can avoid the fixed protective cover, thus avoiding interference between the protective cover device and the fixed protective cover. Compared with the protective cover in the prior art, the protective cover device provided in this embodiment does not need to be repeatedly disassembled and assembled when performing belt maintenance on the belt conveyor equipment, effectively improving the service life of the protective cover device.

[0068] In an alternative embodiment, the driving part 30 provided in this embodiment is located at the side of the frame 40.

[0069] In a specific embodiment, since the protective cover body 212 provided in this embodiment is installed on the side of the support frame 211 close to the track portion 10, when the protective cover portion 20 is in the protective state, the protective cover bodies 212 at both ends of the protective cover portion 20 can be lapped and fitted with the fixed protective covers at both ends of the protective cover portion 20 respectively, thereby preventing dust in the belt conveyor equipment from overflowing.

[0070] In an alternative embodiment, the protective cover body 212 and the fixed protective cover provided in this embodiment are both wavy protective covers. By setting both the protective cover body 212 and the fixed protective cover as wavy protective covers, when the protective cover body 212 is lapped with the fixed protective cover, the cooperation of the wavy structure can reduce the possibility of dust overflow in the belt conveyor equipment.

[0071] In an alternative embodiment, since the height of the second track section 12 provided in this embodiment is higher than that of the first track section 11, and a third track section that gradually inclines toward the side close to the protective cover portion 20 in the direction from the first track section 11 to the second track section 12 is provided between the first track section 11 and the second track section 12, during the process of the protective cover portion 20 switching from the protective state to the maintenance state, it can first be lifted upward to completely disengage the wavy lap joint between the protective cover body 212 and the fixed protective cover, and then be translated, avoiding interference between the protective cover body 212 and the fixed protective cover.

[0072] In an alternative embodiment, since the provided traveling wheel assembly 22 cooperates with the limiting recess 111 when the protective cover portion 20 is in the protective state, and a first guiding inclined surface 1111 that gradually inclines toward the side close to the protective cover portion 20 in the direction from the first track section 11 to the second track section 12 is provided on the side of the limiting recess 111 close to the second track section 12, during the process of the protective cover portion 20 switching from the protective state to the maintenance state, the protective cover portion 20 can first be lifted upward under the cooperation of the traveling wheel assembly 22 and the first guiding inclined surface 1111 to completely disengage the wavy lap joint between the protective cover body 212 and the fixed protective cover, and then be translated, avoiding interference between the protective cover body 212 and the fixed protective cover.

[0073] In summary, implementing the protective cover device and belt conveyor equipment provided in this embodiment has at least the following beneficial technical effects: The protective cover device provided in this embodiment sets the track portion 10 to include a first track section 11 and a second track section 12, and sets the second track section 12 to be higher than the first track section 11, so that the protective cover portion 20 movably installed on the track portion 10 along the extension direction of the track portion 10 can be switched between the first track section 11 and the second track section 12. When it is necessary to protect the maintenance area on the belt conveyor equipment, since the position of the first track section 11 corresponds to the position of the maintenance area, the protective cover device provided in this embodiment can protect the maintenance area by setting the protective cover portion 20 on the first track section 11. When it is necessary to repair the maintenance area on the belt conveyor equipment, the protective cover device provided in this embodiment can avoid the maintenance area by setting the protective cover portion 20 on the second track section 12, thereby facilitating the user to repair the maintenance area of the belt conveyor equipment. At the same time, when there is a fixed protective cover on the belt conveyor equipment, the protective cover portion 20 in the protective state can overlap with the fixed protective cover to provide sufficient protection for the belt conveyor equipment. Since the second track section 12 is higher than the first track section 11, the protective cover portion 20 in the maintenance state can avoid the fixed protective cover, thereby preventing the protective cover device from interfering with the fixed protective cover. Compared with the protective cover in the prior art, the protective cover device provided in this embodiment does not need to be repeatedly disassembled and assembled during belt maintenance of the belt conveyor equipment, effectively improving the service life of the protective cover device.

[0074] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
