Abstract

A life saving rod for a narrow well adopts the structure that the main rod is divided into a plurality of sections which can be lengthened through threaded connection; an openable rocker arm is arranged at the head part of the rod; the rocker arm takes the shape of an umbrella hung upside down; a forearm is connected at the front end of the rocker arm; a rope ring is arranged at the top end of the forearm; and a rope penetrates the rope ring and then goes upwards after being wound around the main rod. When in use, the rocker arm is folded and placed into the well and extends into water near a person falling into the well; the rope is loosened so as to unfold the rocker arm; the person falling into the well can be wrapped in the rocker arm taking the shape of an umbrella hung upside down; the rope is then gradually tightened to catch the person; and finally, the person can be rescued from the well only by lifting the main rod.

Description

A kind of narrow well lifesaving bar

Technical field

The utility model relates to a kind of down-hole safety apparatus, and specifically a kind of rescue falls into narrow well personnel's the instrument of suing and labouring.

Background technology

Now, the deep-well that cloudy well and peasant's drought resisting are used is numerous, go to rescue often see the fire fighter on TV before, but, when rescuing the personnel of those grown-ups and childrens and vague mind, after the lifesaving rigging goes down, they do not know how to bundle, and can not go to help him on same plane because well head is too little again after the rescue personnel goes into the well, have to be by loud explanation many times, group pricks reluctantly, sometimes group pricks incorrect or bundlees unreally, and the danger of falling down is arranged again in the lifting process, and so not only waste is sued and laboured the time, also can cause huge pressure at heart to the quilt person of rescuing, unfavorable to suing and labouring.

The utility model content

In order to overcome that the personnel to fall into well is unfamiliar with or can not to bundle the defective of lifesaving rigging, the utility model provides a kind of narrow well lifesaving bar, this lifesaving bar need not professional binding technology, also goes into the well without the rescue personnel, gets the personnel to fall into well and just it can be rescued as long as the lifesaving bar is stretched into the down-hole.

The utility model solves the technical measures that its technical problem takes, mobile jib is made several pole shapes with metal or other material, whenever save and be threaded, the head of last joint is made warhead shape, the diameter of head is greater than the shaft diameter, the junction forms a circumferential platform, connects several rocking arms with hinge on described platform.The front end of rocking arm connects forearm with movable joint, and the top of forearm is fake fixedly, and one in rope connects pulley, and the other end is passed from the fake of forearm top and walk around back passing upwards of one week of mobile jib from the pulley of one in rope.In the rocking arm above hinge rubber-like is set and pushes away tongue, when upwards tension of rope; rocking arm and forearm can close to the mobile jib center and disturb; and be close to shaft, it is compacted to push away tongue simultaneously, and rocking arm and forearm are in state to be opened; when rope loosens; push away at rocking arm under the effect of tongue, and rocking arm drive forearm resembles the petal sample and opens, and is the umbrella of reversal of the natural order of things after opening.During use, the mobile jib of spreading is stretched into the down-hole, its head passes at one's side from the well that falls, makes rocking arm and forearm be lower than person down the well's health, and payout rocking arm and forearm are opened.Slowly upwards carry mobile jib then, observe the down-hole situation, after the well that confirms is seated on the big arm, slowly haul, making forearm close to disturb to cooperate with rope in the fake to mobile jib gets the person down the well, upwards promote mobile jib, just can rescue the personnel to fall into well, can rescue the purpose that falls into narrow well personnel thereby reach to need not to bundle also.

The beneficial effects of the utility model are, fall into narrow well person a kind of conveniently rescue tool is provided for the rescuer rescues, and are simple in structure, easy to operate.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of structural representation of narrow well lifesaving bar;

State diagram when Fig. 2 is opening of a kind of narrow well lifesaving bar.

Among the figure, 1, mobile jib, 2, rope, 3, fake, 4, forearm, 5, movable joint, 6, rocking arm, 7, push away tongue, 8, hinge, 9, head, 10, cushion.

The specific embodiment

In Fig. 1, make the mobile jib 1 of several pole shapes with metal or other material, the head 9 of mobile jib is made warhead shape, head diameter is greater than mobile jib, and the junction forms the platform of a circumferential, uses hinge 8 to connect several rocking arms 6 on platform; the front end of rocking arm connects forearms 4 with movable joint 5; top of forearm is fake 3 fixedly, and one of rope 2 connects pulley, and the other end is worn from the fake of forearm around mobile jib one all backs and passed from pulley upwards.For rocking arm is opened, elasticity is set in the arm body above the hinge of rocking arm pushes away tongue 7.Be sitting on the rocking arm for fear of the person down the well injured, rocking arm and mobile jib to the liner flexible material of practising physiognomy.

In Fig. 2, after rope 2 loosens, push away in elasticity under the effect of tongue 7, rocking arm and forearm are opened and are stretched and the mobile jib shape that meets at right angles.

Claims

1. one kind narrow well lifesaving bar, the mobile jib mark is saved and is threaded, the most last head of controlling into warhead shape, the diameter of described head is greater than the mobile jib diameter, the junction of head and mobile jib forms the platform of a circumferential, on described platform, connect several rocking arms; the front end of rocking arm connects forearm with movable joint; the top of forearm is fake fixedly; one in rope connects pulley with hinge; the other end from the fake of forearm top, pass around one week of mobile jib the back from the pulley of one in rope, pass and extend upwards, in the rocking arm of rocking arm smooth opening above hinge rubber-like to be set and to push away tongue in order to make.
