Detailed description of the invention
Mine rescue machine of the present utility model, comprises base 10, axle 7, the reel 6 of band bracing frame 14, hangs blue 19.The left end of axle 7 is provided with the first free-wheel clutch 4, right-hand member is provided with the second free-wheel clutch 8, and reel 6 is fixed on the centre of axle 7.The input shaft of the first free-wheel clutch 4 is provided with the laborsaving gear mechanism 2 that resets, and the laborsaving gear mechanism 2 that resets is provided with reset handwheel 3.The output shaft of the second free-wheel clutch 8 is provided with driving gear 16 and energy disperser 9.Base 10 is provided with Hydraulic Pump 12, and the turning cylinder of Hydraulic Pump 12 is provided with the driven gear 13 engaged with driving gear 16, and the outlet hydraulic oil pipe of Hydraulic Pump is connected with compression indicator 17, filter 18 and by pass valve 11 in turn.Bracing frame 14 is provided with bearing seat 5, and axle 7 is arranged in bearing seat 5.
In order to ensure safety, axle 7 is also provided with emergency brake mechanism 1.
Rescuing machine of the present utility model is work like this:
Be fixed on reel 6 by hoist cable 20 one end, mandrel 7 is by hoist cable 20 around on reel 6, and it is firm to be connected with hoist cable 20 by rescue bracketplant 19.
When mine have an accident need rescue group to drop to mine bottom time, the rescuing machine being connected with rescue bracketplant 19 is fixed on the appropriate location of mine, according to the weight of rescue group, regulate the pressure reserving by pass valve 11, guarantee that rescue bracketplant 19 descending speed meets the requirements.Rescue group enters in rescue bracketplant 19, under gravity, rescue bracketplant 19 is automatically to decline, drive axle 7 to rotate around the hoist cable 20 on reel 6, the first free-wheel clutch 4 is separated automatically, the second free-wheel clutch 8 Operating In Persistent Current Mode, driving gear 16 on the output shaft of the second free-wheel clutch 8 engages with driven gear 13, drive Hydraulic Pump 12 to rotate, Hydraulic Pump 12 extracts hydraulic oil from fuel tank 15, flows back to fuel tank 15 after supercharging through by pass valve 11.Along with the decline of rescue bracketplant 19, under the effect of by pass valve 11, oil pressure constantly rises, to increase the drag torque of Hydraulic Pump 12 input shaft, thus hinder the rotation of Hydraulic Pump 12, driven gear 13 is again by driving gear 16 transmission and then the decline rotative speed controlling reel 6, when resisting moment and decline moment balance, will uniform descent be realized, finally play to delay and fall effect, realize the slow decline shaft bottom of rescue group.
After rescue group arrives safe and sound shaft bottom, captive is carried on the back in rescue bracketplant 19 by rescuer, and ground handling operator shakes by reset handwheel 3 laborsaving gear mechanism 2, first free-wheel clutch 4 that resets and closes, drive spindle 7 rotates, second free-wheel clutch 8 is separated automatically, and driving gear 16 does not work, thus Hydraulic Pump 12 does not also work, reel 6 reverses, by hoist cable 20 oppositely around on reel 6, gradually rescue bracketplant 19 is raised to well head, thus completes rescue task.As run into extraordinary circumstances in rescue operations, ground handling operator stops lifting by emergency brake mechanism 1, after pending fault is got rid of, then continues rescue, guarantees that rescue is carried out smoothly, improves the safety and reliability of rescue.
