Abstract
A lifesaving dragging tool for deep and narrow wells comprises a main post, rockers, a protecting wire net and elastic hinges, a roller and lock catches, wherein the rockers are connected to the periphery of the head part of the main post by the elastic hinges, and the rockers are connected with each other by the protecting wire net; and when the lifesaving dragging tool is used, the rockers are first closed to tightly lean against the main post and are locked in the lock holes of the main post by the lock catches, the rockers are parallel to the main post, the head part of the dragging tool is extended below the people fell into a well, then the lock catches are released, the rockers are opened to form a right angle with the main post, meanwhile, the protecting wire net is spread to form a grid type rescue platform, then the main post is slowly lifted so that the people fell into the well can be rescued, and thereby a convenient and rapid simple rescue tool is provided for the rescue personnel.
Description
Technical field
The utility model relates to a kind of down-hole lifesaving appliance, and specifically a kind of rescue falls into dark narrow well personnel's rescue tool.
Background technology
Now, the irrigate the fields well of usefulness of road inspection shaft and peasant is numerous, often the someone falls in people's well, go before the common fire fighter to rescue on TV, because this well head footpath is less, can only hold about the people, when rescuing the personnel of those grown-ups and childrens and vague mind, after the life line instrument went down, they did not know how to bundle, and are too little owing to well head again after the rescue personnel goes down, can not go to help him on same plane, have to be by explanation loudly heap of times, group pricks reluctantly, and sometimes group pricks incorrect or bundlees unreal, the danger of falling down is arranged again in the lifting process, so not only lose time, also can be to being caused huge psychological pressure by the person of rescuing, to continuing to sue and labour and for unfavorable.
The utility model content
In order to overcome the deficiency that the inapplicable rescue of existing lifesaving rigging falls into dark narrow well person, the utility model provides a kind of dark narrow well lifesaving to drag for tool, this drags for the binding technology that tool does not need specialty, also go into the well without the rescuer, as long as this is dragged for tool stretches into by the person's of rescuing below, open the grid structure of head, just the person down the well can be rescued in the well.
The utility model solves the technical measures that its technical problem takes, drag for tool by mobile jib, rocking bar, compositions such as protecting wire net and roller and snap close stay cord, mobile jib is made the hollow more piece, with being threaded, its head is made spherical, spherical diameter is greater than the mobile jib diameter, the joint of head and mobile jib forms the platform of a circumferential, connect rocking bar with elastic hinge around on described platform, rocking bar is made elastic telescopic joint, its head is installed roller, connect with protecting wire net between each rocking bar, the front end of described rocking bar is fixed a rubber-like snap close, on the mobile jib with the corresponding position of snap close open keyhole, when snap close inserted lockhole, the power that can overcome elastic hinge was fixed on parastate with rocking bar and mobile jib.In mobile jib lockhole below a slide block is set, connect extension spring below the slide block, center above the slide block connects stay cord, stay cord protrudes upward mobile jib, the stay cord upper end connects small metal ball, be convenient to guide stay cord to pass the mobile jib endoporus during extension bar, under free state, slide block is below the mobile jib snap close, when the pulling stay cord, slide block upwards, simultaneously the jack-up snap close discharges it, and under the effect of rocking bar elastic hinge, rocking bar is opened and the mobile jib state that meets at right angles, drive protecting wire net simultaneously and open, form the platform of suing and labouring of a grid structure.During use, the below that tool stretches into the person down the well of dragging for of rocking bar gathering, stay cord upwards, rocking bar is opened, when confirming that the person down the well has been on the platform of suing and labouring that drags for tool, just can upwards promote mobile jib, if run into the borehole wall when upwards carrying mobile jib, the roller that is installed in the rocking bar head can play the guiding role, with anti-jamming.Upwards by little, the elastic telescopic of rocking bar can stretch along with the well head diameter variation well head that has, and so just can reach fast, rescue safely person down the well's purpose.
The beneficial effects of the utility model are, and are for rescuer's rescue falls into the instrument of suing and labouring that dark narrow well personnel provide a kind of convenience, safety, simple in structure.
Description of drawings
Below in conjunction with accompanying drawing utility model is described further.
Fig. 1 is the structural representation that tool is dragged in dark narrow well lifesaving.
The locker schematic diagram of tool is dragged in the dark narrow well lifesaving of Fig. 2.
State diagram when the dark narrow well lifesaving of Fig. 3 is dragged for tool and opened.
Among the figure, 1, head, 2, elastic hinge, 3, rocking bar, 4, roller, 5, mobile jib, 6, stay cord, 7, protecting wire net, 8, lockhole, 9, snap close, 10, slide block, 11, extension spring, 12, Metal Ball.
The specific embodiment
In Fig. 1 and Fig. 2, mobile jib 5 is made more piece with being threaded, its head 1 is made sphere, the diameter of head is greater than the mobile jib diameter, the junction forms a circumferential platform, on described platform, connect rocking bar 3 with elastic hinge 2, rocking bar system elastic telescopic joint, its head is installed roller 4 and snap close 9, the corresponding position of mobile jib and snap close open keyhole 8, stay cord 6 stretches into the slide block that connects in the mobile jib in the mobile jib, when rocking bar snap close 9 when mobile jib is drawn close inserts in the lockhole 8 of mobile jib, pin rocking bar, make rocking bar parallel with mobile jib, slide block 10 is set below lockhole, the following connection extension spring 11 of slide block, the top connection stay cord 6 of slide block is when upwards promoting stay cord, the slide block jack-up snap close that makes progress, snap close is discharged, and rocking bar is opened under the effect of elastic hinge, and the stay cord upper end connects Metal Ball 12 usually, this Metal Ball is less than the mobile jib endoporus, and the guiding stay cord passes the mobile jib endoporus when being convenient to extension bar.
Among Fig. 3, after snap close 9 discharged, rocking bar was opened and the mobile jib state that meets at right angles, and the protecting wire net 7 that is connected between the rocking bar opens simultaneously, forms a netted platform of suing and labouring.
