DETAILED DESCRIPTION

[0016] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0017] A protective cover for a belt conveyor, the improvement of which lies in: comprising a mounting seat 1, a protective cover body, a driving device 4 and a control device, the mounting seat 1 being fixedly mounted on a belt conveyor frame, the protective cover body comprising a left protective cover 2 and a right protective cover 3, the left protective cover 2 and the right protective cover 3 being movably connected to the left and right sides of the mounting seat 1 respectively, the driving device 4 being installed between the left protective cover 2 and the mounting seat 1 and between the right protective cover 3 and the mounting seat 1, the driving device 4 being used to drive the left protective cover 2 and the right protective cover 3 to open upward and close downward, the control device being electrically connected to the driving device 4, and the control device being used to control the start and stop of the driving device 4.

[0018] In this embodiment, when the belt conveyor is working normally, the control device controls the driving device to drive the left protective cover 2 and the right protective cover 3 to close downwards to prevent dust. When it is necessary to inspect the parts inside the protective cover body, the control device controls the driving device to drive the left protective cover 2 and / or the right protective cover 3 to open, so as to inspect the left side or right side or both sides of the belt conveyor. The number of driving devices can be multiple, depending on the length of the protective cover body. The control device can control the driving device 4 to work and stop working in real time, so that the left protective cover 2 and the right protective cover 3 stop at any position within their range of activity, which is more flexible. The angle range of the left protective cover 2 and the right protective cover 3 is not less than 90°. When the left protective cover 2 and the right protective cover 3 are turned up 90°, the side panels on their outer sides are in a horizontal state, which can be used to place maintenance tools, which is more practical. Compared with the prior art, the protective cover for a belt conveyor provided in this embodiment can be opened and closed automatically by a control device and a drive device, and the operation is simple, fast, flexible and practical. There is no need to manually disassemble the protective cover body during maintenance, thus avoiding safety accidents caused by improper operation or falling parts during disassembly, and the protective cover is safer and more reliable.

[0019] Furthermore, the driving device 4 includes an electric telescopic rod 42, one end of which is rotatably connected to the mounting seat 1, and the other end of which is rotatably connected to the left protective cover 2 and the right protective cover 3 respectively.

[0020] In this embodiment, when the protective cover body needs to be opened, the control device controls the electric telescopic rod 42 to extend, thereby pushing the left protective cover 2 and / or the right protective cover 3 to lift up. When the protective cover body needs to be closed, the control device controls the electric telescopic rod 42 to retract, thereby driving the left protective cover 2 and / or the right protective cover 3 to close downward.

[0021] Furthermore, a fixing block 41 is installed on the mounting seat 1, and one end of the electric telescopic rod 42 is rotatably connected to the fixing block 41 via a rotating shaft. Sliding guide rails 44 are respectively installed on the left protective cover 2 and the right protective cover 3. A slider 43 is installed on the other end of the electric telescopic rod 42. The slider 43 and the sliding guide rail 44 are cooperatively connected to each other, and the end of the electric telescopic rod 42 and the slider 43 can rotate relative to each other.

[0022] In this embodiment, when the protective cover body needs to be opened, the control device controls the electric telescopic rod 42 to extend, thereby pushing the slider 43 to move along the sliding guide 44 in the direction away from the mounting seat 1, and at the same time pushing the left protective cover 2 and / or the right protective cover 3 to open upward; when the protective cover body needs to be closed, the control device controls the electric telescopic rod 42 to contract, thereby driving the slider 43 to move along the sliding guide 44 in the direction close to the mounting seat 1, and at the same time driving the left protective cover 2 and / or the right protective cover 3 to close downward. The setting of the slider 43 and the sliding guide 44 allows the protective cover body to have a certain buffer time when opening and closing, which is more gentle, and when the protective cover body stops at any position under the control of the control device, there is a certain space to lift it upward, which is more practical.

[0023] Furthermore, the mounting base 1 includes an upper top plate 11, a left support plate 12 and a right support plate 13, the fixing block 41 is fixedly mounted on the left support plate 12 and the right support plate 13, and the left protective cover 2 and the right protective cover 3 are movably connected to the left and right ends of the upper top plate 11 respectively.

[0024] Furthermore, the left supporting plate 12 and the right supporting plate 13 include a vertical portion and a horizontal portion, and the fixing block 41 is installed on the upper end surface of the horizontal portion.

[0025] In this embodiment, the horizontal portions of the left support plate 12 and the right support plate 13 can be used to install the fixing block 41 on the one hand; on the other hand, they can also be used to place maintenance tools, which is more practical.

[0026] Furthermore, the left protective cover 2 and the right protective cover 3 are movably connected to the mounting base 1 via hinges.

[0027] Furthermore, the control device is provided with a control button, and the control button is used to control the left protective cover 2 and the right protective cover 3 to open upwards and close downwards respectively.

[0028] In this embodiment, the opening and closing of the left protective cover 2 and the right protective cover 3 are controlled by control buttons respectively, that is, the left protective cover 2 and the right protective cover 3 can be opened or closed at the same time, or opened and closed separately. In this way, when only one side of the belt conveyor needs to be inspected, the protective cover on the other side does not need to be opened, and it still plays a dust-proof role, which is more practical.
