Description
Technical field
The present invention relates to a kind of rescue door frame, particularly relate to a kind of rescue door frame that crashes into small-bore motor-pumped well personnel for rescue.
Background technology
China has a large amount of motor-pumped wells to spread all over farmland, and the degree of depth can reach tens of rice to rice up to a hundred.Motor-pumped well can go out of use after using year to take out for a long time not water outlet.Discarded motor-pumped well does not have timely backfill, or well lid is in bad repair, and people often fall in well when especially children play.Less motor-pumped well diameter 300-500mm, the rescue of pendant well is very difficult.
At present, the rescue mode that the pendant well is commonly used has: to down-hole, discharge the equipment such as rope, hook ladder, rope ladder, instruct the person down the well to implement to save oneself, if but run into young children, or when darker by card position the method can't implement; Excavate the well casing method, need to drop into more human and material resources, financial resources, rescue time is long, and success rate is low, even may cause the well head landslide, and the rescue personnel is damaged.
At present, published rescue aid has: bondage class such as noose, claw hook, steel ring or umbrella are grabbed part etc., existing problems are to be stuck in while than deep-seated, putting when those who fall well, because rope shake is difficult for realizing fixing human, or fixing unreliable, some is grabbed part and grabs and tie up staff or pin, may damage human body dangerous; The fixture kind equipment is that special fixture is hung in well with rope, and clamping human body shirtfront back, rely on frictional force upwards to promote, and also there is fixing human shortcoming not reliably in this equipment, when the inadequate slippage of frictional force, the head part is caused than major injury; The air bag class is to inflate after the air bag of unaerated is hung in to the human body below, more upwards promotes, and its weak point is that air bag is not easy to pass human body by the position, card division, monolateral tether rope, and stressed rear gasbag distortion, can not pull out those who fall well smoothly; The carriage class is that after a metallic rod was goed deep into to human body below, retracting spring formed carriage, and its deficiency is eccentric force, on easily be stuck while carrying; And the structure of manipulator for rescue or robot and dynamical system complexity are not suitable for more small-bore motor-pumped well rescue yet.

During use, inflate in gas cylinder with source of the gas, observe storage pressure by Pressure gauge, control storage pressure and reach desired value.During rescue, firmly set up tripod at well head, wheel (not shown in FIG.), pass fixed pulley by nylon rope, reliably articulates with being connected to hook on nylon rope and the suspension ring on gas cylinder.Open illuminating lamp, camera, intercom system (not shown in FIG.), total air valve (not shown in FIG.).In original state, telescopic cylinder and rotary cylinder are in retracted state, and the distance between left universal wheel and right universal wheel is than the little about 60-100mm of well head diameter, and the left and right piston that closes up cylinder all is in uppermost position in fig-ure, left and right baffle plate all is near vertical position, and the rescue door frame can sink smoothly.
Shake wheel to sinking rescue door frame slowly in well.When the rescue left column lower end of door frame and right column lower end arrive near the those who fall well head, temporary fixed wheel, but to make the position of left universal wheel and right universal wheel avoid pit shaft seam 23 '.Now, can to those who fall well, cure by oxygen therapy by oxygen supply device, by intercom system and its conversation, link up when possible.Under the help of camera, by the remote control on ground, start the magnetic valve on the telescopic cylinder supply air line, under pressure, the piston rod of telescopic cylinder is overhanging, withstands a little the borehole wall 22 '.Now left universal wheel all contacts with the borehole wall 22 ' with right universal wheel, can overcome door frame and rock; Due to the existence of universal wheel and spring, (being the reaction force of cylinder piston pole pair borehole wall thrust) door frame also can be along the borehole wall around lifting-point rotating under the thrust of the borehole wall 22 ' to the piston rod of forward and backward rotary cylinder.By ground remote controller, front rotary cylinder air feed back piston masthead is lived to the borehole wall 22 ', make to rescue door frame and can rotate counterclockwise in the plane; To after rear rotary cylinder air feed, doing and clockwise rotate.By the piston rod outreach of forward and backward rotary cylinder, control rescue door frame Plane Rotation to the optimum position perpendicular to those who fall well human body width, to facilitate the bottom that is inserted into human body under left and right column.Control forward and backward rotary cylinder exhaust, make the piston rod retraction leave the borehole wall 22 '.Again shake wheel, the door frame of sinking rescue downwards, under now left and right column will vertically be inserted from the neutral gear of the just forward and backward position of those who fall well human body under Gravitative Loads.When the lower end of left column (size of right column is identical with left column) a little more than people's pin near the time, fixing wheel is motionless.By ground remote controller, start the left and right magnetic valve that closes up cylinder, gas cylinder is by gas pipeline to left and right closing up cylinder piston top air feed, and pushing piston moves downward.Under piston rod promotes, the sliding pin down sliding, be initially in vertical left and right baffle plate and around its jointed shaft, rotate into the level of approximation position between person down the well's two legs, two baffle plates of both sides are closed up, by hasp, fasten locking (two side shields can not leave relatively) with buckle, form rigid frame.Now, the rescue door frame completes under the those who fall well hip, reliably entangling the human body task.If botch routines in front, left and right baffle plate, not between the human body both legs, is recoverable to left and right baffle plate, again the door frame position adjust suitable after, again make two baffle plates close up locking.After the rescue door frame entangles human body, can control telescopic cylinder and reset, make the about 60-100mm of door frame width retraction, in can avoiding promoting, door frame is stuck.When two baffle plates of guaranteeing to close up entangle human body between human body two legs, shake wheel, upwards slowly promote rescue door frame and human body to ground.In lifting process, the door frame symmetry is born body weight, and the piston rod of telescopic cylinder only bears axial compressive force and can be crooked.
After transporting those who fall well, to the left and right cylinder piston bottom air feed that closes up, make piston stroking upward, left and right baffle plate resets near vertical position, in order to using next time again.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
