As a further improvement of the invention, the lower side part of the guide sleeve (4) is provided with an opening (20) for the slide block (8) to move up and down.

As a further improvement of the invention, the positioning block group (7) is rotatably connected with the transportation rail bracket (10) through a positioning shaft (6).

As a further improvement of the invention, an upper supporting part (5) is arranged at the position obliquely above the positioning block group (7).

The invention has the beneficial technical effects that:

the automatic positioning device for the movable plate feeder performs automatic positioning through the dual functions of the rail clamping group and the positioning device, thoroughly solves the problems that the movable plate feeder is not influenced by ore bin ore discharging impact force after being accurately positioned in the bin dumping process, prevents the impact force from pushing the movable plate feeder to automatically move, and avoids major accidents of cart sliding and belt gallery blockage. Because the gap between the jaw of the rail clamping device and the two sides of the steel rail is extremely small, the jaw is abraded, the braking capacity is reduced, the reliability is reduced, in order to improve the automatic positioning reliability, a positioning mechanism is arranged on the side surface of the rail clamping device, the mechanism pushes a sliding block to be inserted into or separated from a positioning block group for positioning by a guide plate, a guide limiting block and a guide rod, thus the automatic double positioning of the movable plate type feeding machine is realized by utilizing the double repositioning of the jaw of the rail clamping device and the positioning block group, and the safety and reliability are improved.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

As shown in fig. 1-4, an automatic positioning device for a movable plate feeder comprises a jaw thrust rod 13, wherein a jaw 12 for clamping a transport rail is installed at the bottom of the jaw thrust rod 13, a lifting part 19 is arranged in the middle of the top end of the jaw thrust rod 13, the lifting part 19 is driven by a piston 17 in a hydraulic thrust rod 16 to move up and down, a spring upper pressing plate 15 is connected to the side part of the lifting part 19, a spring 14 is fixed between the spring upper pressing plate 15 and a base 18, and the spring 14 is compressed or released by the movement of the piston 17 of the hydraulic thrust rod 16; a guide plate 1 is welded on the side surface of the upper spring pressure plate 15, a guide limit 2 is arranged on one side of the guide plate 1, and the guide plate 1 stirs the guide limit 2 to move up and down; the guide limiting device comprises a guide rod 3, a guide block 8, a guide limit 2, a guide sleeve 4, a guide rod 3, a positioning block group 7 and a guide block 8, wherein the guide limit 2 is fixed at the top end of the guide rod 3, the guide rod 3 is sleeved in the guide sleeve 4, and the sliding block 8 is matched with the positioning block group 7 arranged on the side face of a transport steel rail bracket 10. The bottom of the guide sleeve 4 is provided with a limit sleeve 9, the side part below the guide sleeve is provided with an opening 20 for the slider 8 to move up and down, the positioning block group 7 and the transportation steel rail bracket 10 are rotatably connected through a positioning shaft 6, and an upper support part 5 is arranged at the position obliquely above the positioning block group 7.

The automatic positioning device for the movable plate feeder is arranged in front of the movable plate feeder, and one or more groups of automatic positioning devices can be arranged as required in practical application. In the operation process of the movable plate feeder, when the movable plate feeder approaches to the action distance of a switch, a piston 17 of a hydraulic thrust rod 16 of an automatic positioning device of the movable plate feeder moves upwards, a jaw thrust rod 13 drives a jaw 12 of a rail clamping device to clamp a steel rail 11, meanwhile, a spring 14 moves upwards, a guide plate 1 connected with a spring upper pressure plate 15 is driven to move upwards, a toggle guide limit 2 moves upwards, the guide limit 2 drives a guide rod 3 and a slide block 8 to slide upwards in a guide sleeve 4, the slide block 8 lifts a corresponding positioning block in a positioning block group 7, the positioning block adjacent to the positioning block and the slide block 8 are positioned, and the movable plate feeder is automatically positioned under the dual functions of the jaw thrust rod 13 and the slide block 8. If the power is cut off due to an abnormal fault, when the piston 17 of the hydraulic thrust rod 16 cannot move upwards, the spring 14 only moves upwards to drive the spring upper pressing plate 15 to move upwards, and double positioning of the jaw thrust rod 13 and the slide block 8 can also be realized. If the piston 17 of the hydraulic thrust rod 16 contracts, the spring upper pressing plate 15 is driven to compress the rail clamping device spring 14 to move downwards, the jaw 12 of the rail clamping device is separated from the steel rail 11, meanwhile, the guide plate 1 connected with the spring upper pressing plate 15 moves downwards, the guide limit 2 is stirred to move downwards, the guide limit 2 drives the guide rod 3 and the slide block 8 to slide downwards together in the guide sleeve 4, the slide block 8 slides down and is separated from the positioning block group 7, and the movable plate type feeding machine is released from positioning and can freely move left and right on the steel rail.
