Personnel approach induction intelligent telescopic protection device

Abstract

The utility model discloses a personnel approach induction intelligent telescopic protection device, and relates to the technical field of induction intelligent telescopic protection devices. The supporting frame is welded to the rear portion of the front arm cannon head of the roadheader, and after the inductor induces that a person approaches, the oil cylinder is controlled to push the inductor forwards to slide outside the sliding rod, so that the sliding rod slides out of the front arm cannon head of the roadheader, and the sliding rod slides out of the front arm cannon head of the roadheader. When a sliding block at the bottom of a connecting rod is clamped into a downwards-bent groove in one end of a sliding groove for fixing a gear arranged on the side face of an inductor, the gear rotates to drive a rack clamped to the top of a connecting plate to move towards one end, so that a second gear meshed to the top of the connecting plate rotates clockwise when the rack moves, and a protection plate is downwards driven to turn over; and the forearm cannon head of the roadheader is enclosed by the protection plate, so that people are prevented from being injured when approaching the forearm cannon head.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 The utility model provides a technical solution: a personnel approach sensing intelligent telescopic protection device. It includes a telescopic protection component 1, which includes a support frame 11. One end of the support frame 11 is fixedly connected to a slide bar 13. The outside of the slide bar 13 is slidably connected to a sensor 14. The sensor 14 can detect the distance of the human body, and the distance can be adjusted. The adjustable radius is about half a meter; the detection area is wide because the detection area is double-sector shaped; it has a high adaptability to the ambient temperature range. One end of the sensor 14 is fixedly connected to an oil cylinder 12. The oil cylinder 12 can transmit a signal to the control end to start the oil cylinder 12 when the sensor 14 detects that a person is approaching, and drive the sensor 14 to slide along the outside of the slide bar 13. The other end of the sensor 14 is fixedly connected to an extension rod 19. The bottom of one end of the sensor 14 extends downward and is movably connected to a gear 17. The surface of the gear 17 is fixedly connected to a connecting rod 113. A side fixed bracket 15 is fixedly connected to the side of the support frame 11, and a slide groove 16 is provided inside the side fixed bracket 15. When the sensor 14 moves toward one end of the support frame 11, the gear 17 and the connecting plate 18 are first relatively stationary with the sensor 14. When the connecting plate 18 rotates to the downwardly bent part at one end of the slide groove 16, the connecting rod 113 drives the gear 17 to rotate downward. When the gear 17 rotates, it drives the rack sliding above the connecting plate 18 to move. The rack drives the second gear 111 set at one end of the connecting plate 18 to rotate, so that the protective plate 112 fixedly connected to one end of the second gear 111 flips downward and wraps around the rear of the forearm gun head of the comprehensive excavator. The extension rod 19 is movably connected with a fixing part 115 inside. A rotating shaft 110 extends outward from one end of the fixing part 115, and one end of the rotating shaft 110 is movably connected to the second gear 111.

[0020] See also Figure 1-4One end of the oil cylinder 12 is fixedly connected to the inner side of the support frame 11, and the other end of the oil cylinder 12 is fixedly connected to the sensor 14. The bottom of the sensor 14 extends downward and is fixedly connected to a connecting plate 18. A gear 17 is meshed at one end of the top of the connecting plate 18, and a second gear 111 is meshed at the other end of the top of the connecting plate 18. A protective plate 112 is fixedly connected to the bottom of the rotating shaft 110. The top of the support frame 11 is an arc-shaped structure. The setting of the arc-shaped structure enables the device to be welded behind the forearm gun head of the comprehensive excavator. A slider 114 is protruded at the bottom of the connecting rod 113, and the slider 114 is slidably connected to the inside of the slide groove 16.

[0021] When in use, when the sensor 14 detects that a person is approaching, the oil cylinder 12 is first controlled to push the sensor 14 forward to slide on the outside of the slide rod 13. Since the gear 17 arranged on the side of the sensor 14 is engaged with the slider 114 at the bottom of the connecting rod 113 and is fixed in the groove bent downward at one end of the slide groove 16, the gear 17 rotates to drive the rack engaged with the top of the connecting plate 18 to move to one end, so that the second gear 111 engaged with the top of the connecting plate 18 rotates clockwise when the rack moves, and drives the protective plate 112 to flip downward, so that the protective plate 112 blocks the forearm gun head of the comprehensive excavation machine to prevent injuries when people approach; when the comprehensive excavation machine is working, the oil cylinder 12 drives the sensor 14 to slide backward, so that the protective plate 112 arranged at one end rotates to a parallel position by engaging with the surface of the connecting plate 18, and is received between the gap between the top of the side fixing bracket 15 and the bottom of the support frame 11, so as to avoid the protrusion of the protective plate 112 affecting the operation of the comprehensive excavation machine during the operation of the comprehensive excavation machine.
