BRIEF DESCRIPTION OF THE DRAWINGS
[0016] Figure 1 It is a structural schematic diagram of the utility model.
[0017] Figure 2 for Figure 1 Schematic diagram of the structure of the mid-height adjustment device. DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1As shown, an anti-falling overhead passenger device for mines which is convenient for quick getting off the vehicle comprises a hanging plate 1, an upper hanging rod 2, a height adjustment device 3, a lower hanging rod 4 and a seat 5. The hanging plate 1 is clamped on the transport steel cable, and the top of the upper hanging rod 2 is connected to the hanging plate 1 through a rotating bearing. During transportation, the inclined transport steel cable will not affect the upper hanging rod 2 to remain vertical; the bottom of the upper hanging rod 2 is connected to the lower hanging rod 4 through the height adjustment device 3, and the bottom of the seat 5 is fixed to the lower hanging rod 4 through a connecting rod 11. The seat 5, the connecting rod 11 and the lower hanging rod 4 are integrally cast and die-cast, and a footrest 6 is provided at the bottom of the lower hanging rod 4; the top of the safety backrest 8 is installed on the height adjustment device 3 through a backrest rotating device, and the bottom of the safety backrest 8 is fixed to the seat 5 through a buckle 9.
[0020] like Figure 2 As shown, the height adjustment device 3 includes a first spring 13 and an outer sleeve 14, the first spring 13 is located in the outer sleeve 14, the upper end of the first spring 13 is exposed from the top of the outer sleeve 14 and is fixedly connected to the bottom of the upper suspension rod 2, the upper part of the lower suspension rod 4 is sleeved in the outer sleeve 14, and the top of the upper suspension rod 2 is fixedly connected to the lower end of the first spring 13, a plurality of limiting holes 15 are arranged in sequence from top to bottom on the upper part of the upper suspension rod 2, a through hole is provided on the wall of the outer sleeve 14, a pin 16 is inserted through the through hole into the corresponding limiting hole 15 for limiting, and an armrest 7 is provided in the middle of the outer sleeve 14. In the initial state, the latch 16 is inserted through the through hole into the limiting hole 15 arranged at the lower position. If the latch 16 is pulled out, the first spring 13 is stretched under the action of the worker's own weight, and the lower suspension rod 4, the seat 5, the safety backrest 8, the backrest rotation device, and the outer sleeve 14 move downward as a whole, so that the distance between the seat 5 and the ground is reduced; when the length of the first spring 13 no longer extends, the latch 16 is inserted through the through hole into the limiting hole 15 arranged at the upper position again to achieve locking, so that the length of the first spring 13 after stretching is fixed and no longer changes.
[0021] The backrest rotating device includes a collar 12, a second spring 10 and a pin, one end of the collar 12 is rotatably mounted on the top of the cylinder wall of the outer sleeve 14 through the pin, and the other end of the collar 12 is fixedly connected to the top of the safety backrest 8. One end of the second spring 10 is fixed to the top of the cylinder wall of the outer sleeve 14, and the other end of the second spring 10 is fixed to the collar 12, and the second spring 10 is used to open the safety backrest 8 upward.
[0022] The working process of the utility model is as follows: at the boarding place, the safety backrest 8 is fixed to the seat 5 by the buckle 9. Before boarding, the buckle 9 is opened, so that the safety backrest 8 rotates upward under the elastic force of the second spring 10 of the backrest rotating device. At this time, the worker can grasp the upper suspension rod 2 or the armrest 7 and sit on the seat 5. After the worker sits firmly on the seat 5 and puts both feet on the footrest 6, the safety backrest 8 is pulled to rotate downward, so that the bottom of the safety backrest 8 is fixed to the seat 5 by the buckle 9. At this time, the worker is fixed to the seat 5 by the safety backrest 8, which greatly reduces the risk of the worker falling while waiting for the bus. When an emergency accident causes the monkey car to stop midway, the worker can pull out the pin 16 on the height adjustment device 3, and pull the first spring 13 inside the height adjustment device 3 by the worker's own weight, so that the lower suspension rod 4, the seat 5, the safety backrest 8, the backrest rotation device, and the outer sleeve 14 move downward as a whole, so that the distance between the seat 5 and the ground is reduced. When the length of the first spring 13 is no longer extended, the seat 5 has dropped to a safe height. At this time, the pin 16 is inserted through the through hole into the corresponding limit hole 15 again to achieve locking. Then the worker opens the buckle 9 on the seat 5, and under the elastic force of the second spring 10 of the backrest rotation device, the safety backrest 8 rotates upward, and the worker can get off the car safely.
