Detailed Description
As shown in fig. 1-7, a mine drop shaft ore discharge port in the prior art comprises a vibration bedplate 1, side plates 2 are arranged on two sides of the vibration bedplate 1, a cross beam 3 is arranged above the vibration bedplate 1, the safety protection device for the mine drop shaft ore discharge port comprises a baffle 5, a hanging ring 501 is arranged on the top surface of the baffle 5, the width of the baffle 5 is smaller than the distance between the two side plates 2, the baffle 5 is connected between the two side plates 2, the bottom surface of the baffle 5 is placed on the top surface of the vibration bedplate 1, an electric hoist 8 is fixedly connected to the bottom surface of the cross beam 3, the electric hoist 8 comprises a steel wire rope 9, the end part of the steel wire rope 9 is connected with a hook 10, and the hook 10 is connected to the hanging ring 501.
The two side plates 2 are provided with first rotating covers 4 on the top surfaces, the first rotating covers 4 are arch-shaped cover bodies with downward openings, the openings at the lower ends of the first rotating covers 4 are fixedly connected to the top surfaces of the side plates 2, the side surfaces of the baffle plates 5 are provided with second rotating covers 6, the side surfaces of the baffle plates 5 are provided with two second rotating covers 6, the second rotating covers 6 are arch-shaped cover bodies with downward openings, the openings of the second rotating covers 6 are fixedly connected to the side surfaces of the baffle plates 5, the utility model also comprises a connecting rod 7, the connecting rod 7 comprises a long rod 701, a first supporting rod 702 and a second supporting rod 703, the first supporting rod 702 and the second supporting rod 703 are respectively connected to two ends of the long rod 701, the first supporting rod 702 and the second supporting rod 703 are parallel, the first supporting rod 702 is rotatably connected to the first rotating covers 4, the second supporting rod 703 is rotatably connected to the second rotating covers 6, and the connecting rod 7 is connected between the two first rotating covers 4 and the two second rotating covers 6.
One end of the first support rod 702 far away from the long rod 701 extends out of the first rotating cover 4, a clamping groove 704 is formed in the outer wall of the end part of the first support rod 702 extending out of the first rotating cover 4, and a check ring 11 is clamped in the clamping groove 704; one end of the second support rod 703 far away from the long rod 701 extends out of the second rotating cover 6, a clamping groove 704 is formed in the outer wall of the end part of the second support rod 703 extending out of the second rotating cover 6, and a check ring 11 is clamped in the clamping groove 704.
When the ore pass ore drawing port of the mine drop shaft works normally, the baffle 5 is lifted by the electric hoist 8, the baffle 5 can not block the vibration bedplate 1 after being lifted, and at the moment, ore is discharged through the vibration bedplate 1. When the ore pass of the mine drop shaft is not used for ore drawing, the electric hoist 8 is used for drawing down the baffle plate 5, and the width of the baffle plate 5 is smaller than the distance between the two side plates 2, so that the baffle plate 5 can prevent ore from falling down from the ore pass, thereby ensuring the safety of operators below the drop shaft, and avoiding slag generation below the drop shaft to slightly increase the labor intensity of the operators.
Only using electric block 8 to be connected with baffle 5 exists when the ore accident drops and smashes to baffle 5, exists the ore and hits the risk that overturns and thereby continue dropping with baffle 5, so the utility model has increased first rotation cover 4, second rotation cover 6 and connecting rod 7, rotate cover 6 and connecting rod 7 through first rotation cover 4, second rotation and make baffle 5 rotate and connect on curb plate 2, avoided because the ore hits the condition that causes baffle 5 to smash and overturn, has effectively improved the stability in use and the security of the utility model.
In addition, due to the arrangement of the first rotating cover 4, the second rotating cover 6 and the connecting rod 7, the movement track of the baffle plate 5 during lifting is circular movement taking the first rotating cover 4 as an axis, and the circular movement of the baffle plate 5 can be supplemented by the deflection of the steel wire rope 9 because the connection mode of the electric hoist 8, the steel wire rope 9, the hook 10 and the baffle plate 5 is not rigid, and the lifting height of the baffle plate 5 is not too high in actual use, and only the baffle plate 5 is required to be lifted to be higher than the bottom surface of the baffle plate 5 and the top surface of the side plate 2, so the connection mode of the utility model has flexible and stable action and can not be blocked.
The arrangement of the clamping groove 704 and the retainer ring 11 prevents the connecting rod 7 from accidentally falling out of the first rotating cover 4 or the second rotating cover 6 during use, so that the use stability and the safety of the utility model are ensured.
When the vibration table plate 1 is used in a site without the beam 3 at the ore pass of a mine with a special structure, the electric hoist 8 can be fixed at other positions above the vibration table plate 1 or a supporting structure can be independently arranged.
The retainer ring 11 in the present utility model may use a circlip, a fixed ring, a stopper ring, a lock collar, or the like as long as it can satisfy the prevention of the connecting rod 7.
