Embodiment 1
A kind of descending lifeline, including hoist engine 1, hydraulic oil pump 4 and circulating oil path device, the hoist engine of the hoist engine 1
3 both ends of axis are in mating connection with the hoist engine support of bearing 2 respectively, and 2 outer end of the hoist engine support of bearing described in two is each attached to
On shell 17, the port of export of the steel wire rope 8 on hoist engine 1 and A hooks 9 are connected, and it is right therewith that one end of elevator arbor 3 passes through
The hoist engine support of bearing 2 answered, and winding gear 18 is installed on it, the winding gear 18 and reduction gearing
16th, reduction gearing 16 is intermeshed setting two-by-two with hydraulic oil pump gear 20, and a limiter of speed 21 is installed in 16 one end of reduction gearing,
The hydraulic oil pump gear 20 is connected with the line shaft of hydraulic oil pump 4；
The circulating oil path device include oil cylinder 12, fuel tank 13, check valve 6 and pressure limiting valve 7, the hydraulic oil pump 4,
Check valve 6, oil cylinder 12 and fuel tank 13 pass sequentially through oil pipe 5 and are connected, delivery outlet and the check valve 6 of the hydraulic oil pump 4
Oil inlet be connected, the delivery outlet of check valve 6 is connected with the import of oil cylinder 12, the outlet of the oil cylinder 12 and pressure limiting valve 7
Import is connected, and the outlet of pressure limiting valve 7 is connected with 13 one end of fuel tank button, other end button and the 4 oil inlet phase of hydraulic oil pump of fuel tank 13
Even, a circulating oil path is collectively formed in hydraulic oil pump 4, check valve 6, oil cylinder 12, pressure limiting valve 7 and fuel tank 13.
In the present embodiment, the hydraulic oil pump 4 is gear oil pump or pillar oil pump.
In the present embodiment, the reduction gearing 16, hydraulic oil pump gear 20 pass through reduction gearing stent, hydraulic oil respectively
Pump tooth wheel support 24 is fixed on the shell.
In the present embodiment, described 17 liang of outer ends of shell are respectively equipped with fixed screw holes 15.
In the present embodiment, the pressure limiting valve sets graduation apparatus, under graduation apparatus setting is per second according to adjustment oil pump capacity size
The distance of drop, meter per second.
In the present embodiment, the oil cylinder 12, fuel tank 13 are arranged on inside shell 17.
In the present embodiment, 12 one oil filler 22 of top setting of oil cylinder.
In the present embodiment, according to car belt operation principle, a limiter of speed 21 is installed in 16 one end of reduction gearing, when slow
When dropping decrease speed of the device decrease speed more than design, the centrifugation tooth on limiter of speed 21 blocks reduction gearing 16, and elevator arbor 3 stops
Rotation stop is moved, and descending lifeline stops declining.
Installation process：The 17 both sides fixed screw holes 15 of shell of descending lifeline are mounted to a wall, close pressure limiting valve 7, installation
It finishes.
During slow drop, when A hooks 9 hang up weight 11 or slow drop personnel 19, hoist engine 1 starts to rotate, winding gear 18
Transmitting hydraulic oil pump gear 20 drives hydraulic oil pump 4 to 12 pump oil of oil cylinder, when pressure limiting valve 7 is closed, 12 note of oil cylinder
Full hydraulic oil 14, pressure increase, makes oil pump 4 stop pump oil, and oil pump gear 20 stops operating, and hydraulic oil pump gear 20 is driven to volume
Machine gear 18 is raised, preventing hoist engine 1, weight 11, which is hung over, cannot vacantly move down from rotating；
When opening pressure limiting valve 7, for example 0.5 meter per second of scale is set as, 12 pressure of oil cylinder reduces at this time, and oil pump 4 starts to pump
Oil, oil circuit 5 form a circuit by 7 → fuel tank of fuel tank 13 → hydraulic oil pump, 4 → check valve, 6 → oil cylinder, 12 → pressure limiting valve 13,
Since 7 oil pump capacity of pressure limiting valve is smaller, (oil cylinder working-pressure becomes larger) hydraulic oil pump 4 is rotated by resistance, 4 slow rotation of hydraulic oil pump,
It is driven again and gives hoist engine 1 slow rotation, weight 11 enters slow drop state.Descending lifeline is with 0.5 meter per second uniform descent.
Pressure limiting valve 7, the increase of 12 pressure of oil cylinder are closed, oil pump 4 stops pump oil, and hoist engine 1 stops operating, under weight 11 stops
Drop.
Embodiment 2
A kind of descending lifeline, as shown in Figure 2, the lifesaving hydraulic descent control device are portable, and the hydraulic bjuffer is different from reality
It is that A hooks 9 are hung on wall body fixing device to apply example 1, and B hooks 10 fix slow drop personnel 19, and entire lifesaving hydraulic descent control device is in company with slow
Drop personnel 19 decline together, delay the control pressure limiting valve 7 manually of drop personnel 19, when pressure limiting valve 7, descending lifeline is turned off manually in slow drop personnel 19
Gentle drop personnel 19 are in stopping decline state.
During slow drop, delay drop personnel 19 and open pressure limiting valve 7 manually, for example open pressure limiting valve 7 and be set as 0.5 meter per second of scale, oil
Road 5 forms a circuit, hoist engine by 7 → fuel tank of fuel tank 13 → hydraulic oil pump, 4 → check valve, 6 → oil cylinder, 12 → pressure limiting valve 13
1 under human bady gravitational effect, drives hydraulic oil pump 4 to rotate, since setting 7 oil pump capacity of pressure limiting valve is smaller, the increase of 12 pressure of oil cylinder,
Hydraulic oil pump 4 is rotated by resistance, makes 4 slow rotation of hydraulic oil pump, then is driven and is given hoist engine 1 slow rotation, delays drop personnel 19
Into slow drop state.Descending lifeline is with 0.5 meter per second uniform descent.
Embodiment 3
