Description

Technical Field

[0001] The utility model belongs to the technical field of waste rock turning devices, and in particular relates to a waste rock leakage prevention device for a waste rock turning platform in chute construction. Background Art

[0002] Mine chute construction is one of the projects in the mining and production process of metal and non-metallic ores. The main contents of its shaft excavation construction include rock drilling and blasting, and waste rock support. That is, the main function of the waste rock turning platform is to pour the waste rock lifted by the bucket into the mine car or the waste rock turning pit. During the waste rock turning process, some of the waste rock does not slide through the waste rock turning funnel chute but directly falls from the waste rock turning platform, posing a safety hazard. Utility Model Content

[0003] The utility model provides a waste rock leakage prevention device for a waste rock turning platform in chute construction, aiming to reduce the hidden danger that part of the waste rock does not slide down through the waste rock turning funnel chute but directly spills from the waste rock turning platform.

[0004] To this end, the present invention adopts the following technical solutions:

[0005] A device for preventing the leakage of waste rock from a waste rock turning platform for chute construction comprises a steel frame of an inclined chute of the waste rock turning platform, the upper portion of the chute having a large opening, a transitional closing portion in the middle portion of the chute, and a small opening in the lower portion of the chute, wherein a semi-cylindrical protective cover is buckled and connected to the middle and upper portions of the chute, the left side of the protective cover being rotatably connected to the left side of the chute via a rotating shaft, and the right side of the protective cover being fixedly connected to the right side of the chute via a latch;

[0006] It also includes a monitoring unit, which includes a controller, an infrared transmitter, an infrared receiver, a buzzer and a video monitor. The infrared transmitter is arranged at intervals along the upper edge of the protective cover, and the infrared receiver is arranged at intervals along the lower edge of the protective cover. The infrared light penetrates the protective cover, and the buzzer alarms when the infrared receiver is triggered; the video monitor is set at the upper edge of the protective cover to monitor the situation inside the protective cover.

[0007] Furthermore, it also includes a transmission assembly for opening the protective cover. The transmission assembly includes a motor and a reducer arranged on the left side of the chute. The reducer output shaft is fixedly connected to the protective cover shaft through a coupling. When the motor rotates, it drives the protective cover to open or close.

[0008] Furthermore, the lower end of the protective cover is connected to a support frame, which is fixed on the inclined chute steel frame of the gangue turning platform. The support frame is used to prevent the protective cover from sliding down.

[0009] The beneficial effects of the present invention are:

[0010] After the bucket is lifted to the material turning platform, the waste is turned and dumped into the inclined chute of the waste turning platform. Under the protection of the protective cover, the waste is prevented from being scattered outside the chute during the turning process. When the waste blocks the protective cover, the infrared sensor detects the signal and the buzzer alarms. The staff removes the pin on one side of the protective cover and controls the motor to open the protective cover to clean the waste. After cleaning, the protective cover is closed again, which greatly improves work safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 3 As shown, a device for preventing the leakage of waste rock on a waste rock turning platform for chute construction comprises an inclined chute steel frame 1 of the waste rock turning platform, the upper opening of the chute is large, the middle part of the chute is closed and transitioned, the lower opening of the chute is small, and a semi-cylindrical protective cover 2 is buckled and connected to the middle and upper positions of the chute. The left side of the protective cover 2 is rotatably connected to the left side of the chute through a rotating shaft 3, and the right side of the protective cover 2 is fixedly connected to the right side of the chute through a pin 4. The lower end of the protective cover 2 is abutted against a door-shaped support frame, the contour of the support frame fits the protective cover 2, and the support frame is fixed to the inclined chute steel frame 1 of the waste rock turning platform. The support frame is used to prevent the protective cover 2 from sliding down.

[0018] The system also includes a monitoring unit, which includes a controller, infrared transmitters 8, infrared receivers 9, a buzzer 10, and a video monitor 7. The infrared transmitters 8 are spaced apart along the upper edge of the protective cover 2, and the infrared receivers 9 are spaced apart along the lower edge of the protective cover 2. Infrared light penetrates the protective cover 2, and when the infrared receivers 9 are triggered, the buzzer 10 sounds an alarm. The video monitor 7 is located at the upper edge of the protective cover 2 and is used to monitor the situation inside the protective cover 2. To prevent false alarms from the buzzer 10, a time-delay relay is connected to the controller. If the infrared signal continues to trigger for 30 seconds, indicating a gangue blockage, the buzzer 10 will activate an alarm.

[0019] The system also includes a transmission assembly for opening the protective cover 2. The transmission assembly comprises a motor 5 and a reducer 6, located on the left side of the chute. The output shaft of the reducer 6 is fixedly connected to the rotating shaft 3 of the protective cover 2 via a coupling. Rotation of the motor 5 drives the protective cover 2 to open or close. The system also includes two limit switches, each of which controls the opening and closing angles of the protective cover 2. When a limit switch is triggered, the motor 5 stops rotating.
