Description
Technical field
The present invention relates to downhole rescuing technical fields, and in particular to a kind of deliverance apparatus.
Background technique
Since down-hole accident is multiple, the situation of downhole rescuing is very severe.The success or failure of downhole rescuing depend primarily at 3 points：
The first, can rescue personnel reach the scene of the accident in a short time and understand the actual conditions of the scene of the accident；It the second, can be rapid
Effective rescue method is according to circumstances formulated on ground, carries out rescue deployment；Can third correctly direct rescue work implementation, and measure obtains
Power is organized proper.Wherein live rescue is implemented to be the most critical factor for determining rescue success, if field rescue is implemented
It is unsuccessful, no matter reach scene how rapidly, how perfect that rescue method formulates ground is, be all to talk about stratagems on paper, without actual effect,
The problem of how safely people being rescued to be only downhole rescuing real concern rapidly.If there is a kind of rescue dress of highly effective and safe
It sets, it is clear that the chance of success of downhole rescuing can be greatly improved.
Structure is complicated for deliverance apparatus in the prior art, with high costs, is not suitable for the arduous area of condition and implements underground
Rescue.Such as Chinese patent document CN207377601U discloses a kind of coal mine rescue lifesaving appliance, including pipeline is climbed
Row device, the first fixed plate, the second fixed plate, hinge, four-bar mechanism, air bag body, supporting leg, first segment gasbag chamber, the second section
Gasbag chamber and third section gasbag chamber, first fixed plate are fixed with four-bar mechanism by hinge, in the pipe crawling device
It is provided with air bag body, is fixed with supporting leg on the four-bar mechanism.
Chinese patent document CN104587624A discloses a kind of underground rescue fisher, which includes
Rescue plate and brucker survival capsule, the rescue plate side of brucker survival capsule lower end are equipped with positioning disk, and positioning disk connects pin shaft and lifesaving by main body
Device connection, brucker survival capsule upper end are fixed among rescue plate side by stud fixing connection chain extension bar, brucker survival capsule
Nut, drawstring A pass through nut and are fixedly connected with the threading pull rod being fixed on rescue plate, and brucker survival capsule is oriented to far from rescue plate side
Disk upper end is equipped with positioning pin, is fixed with drawstring B in the through-hole of positioning pin.When someone falls into underground accidentally, operator
Chain extension bar 6 is installed according to the depth of well, gos deep into brucker survival capsule 2 slowly in well along the borehole wall, the bottom until falling on device for underground man car, behaviour
Make the drawstring A that personnel pull connection rescue plate 1, makes rescue plate 1 and brucker survival capsule 2 at 90 degree, positioning pin 10 blocks positioning disk 3 at this time
So that rescue plate 1 stablize with 2 plumbness of brucker survival capsule, then falling man stand (seat) on rescue plate 1, embrace chain extension bar 6, on
The operator in face can slowly pulling chain extension bar 6 draw safely personnel to fall into well to ground, if being in an emergency, pull and draw
B11 restrict for 10 pull-up of positioning pin, rescue plate 1 and brucker survival capsule 2 can be made to get rid of plumbness.
It can be seen that deliverance apparatus in the prior art or structure is complicated, with high costs or safety is poor, as in
Underground rescue fisher disclosed in state patent document CN104587624A holds in rescue operations without corresponding safeguard procedures
It easily causes and injury is scratched by the secondary of rescue personnel, be unfavorable for the life security of guarantee personnel.
