Abstract

The utility model provides an underground rescue apparatus, which is characterized in comprising a pull rod and a support bracket; wherein, the support bracket comprises a plurality of end rings, a support strip, a plurality of bracing strips and a sliding sleeve; the end rings are fixed at the top of the pull rod; the sliding sleeve is sleeved in the pull rod; one end of the support strip is moveably fixed on the end rings; one end of the bracing strips is moveably fixed on the sliding sleeve, while the other end is moveably fixed at the centre of the support strips; a connecting piece is arranged between the support strips. The utility model has the advantages of strong adaptability, and applicability for rescue in both a large well shaft and a small well shaft, and good safety performance.

Description

Underground lifesaving apparatus

Technical field:

The utility model relates to a kind of lifesaving appliance, particularly a kind of lifesaving appliance used after the people falls into well--underground lifesaving apparatus.

Technical background: after the people fell into well, existing used lifesaving appliance and mode mainly contained: 1, put into aerial ladder to the down-hole, allow people from down-hole outside aerial ladder climbs out of well; 2, put into hanging basket to the down-hole, allow the falling man be sitting in the hanging basket, the people is hung out outside the well by hanging basket; 3, the rescue personnel ties up with bandage, with lifting rope the rescue personnel is put into well, and the rescue personnel holds the falling man tightly and together hung out outside the well by lifting rope.The deficiency that above-mentioned lifesaving appliance and mode in use exist is: one, adaptability is narrow, 1., when the people falls into the well of pit shaft less (its diameter is less than the width of a person), then be difficult to use, especially all the more so when human body is stuck in the pit shaft, aerial ladder and hanging basket all can not by human body be put into human body below, therefore be difficult to sue and labour; Hold the falling man tightly restriction that the rescue mode that is together hung out by lifting rope is subjected to mineshaft diameter especially and the rescue personnel is put into well with lifting rope.2., when using the aerial ladder rescue, its precondition is that the falling man has enough muscle power to climb aerial ladder, if the falling man is injured or in poor health, then the aerial ladder rescue can not adapt to.Two, safety coefficient is not high, the mode of hanging basket and holding all have hanging basket because of reason such as come off, holding is not held tightly cause that the falling man falls down again may.

Summary of the invention:

The purpose of this utility model is, at having the existing deficiency of well lifesaving appliance now, and proposes that a kind of adaptability is strong, safety coefficient is high, especially adapts to the underground lifesaving apparatus of giving first aid in the less well of mineshaft diameter.

Can realize the purpose of this utility model by following technical proposals, a kind of underground lifesaving apparatus is characterized in that it is made of pull bar, support, and support is made of end ring, stay, lattice framing, sliding sleeve; End ring is fixed on the top of pull bar, and sliding sleeve is enclosed within the pull bar, and stay one end activity is fixed on the end ring, and lattice framing one end activity is fixed on the sliding sleeve, and other end activity is fixed on the middle part of stay, is provided with connector between the stay.

For support is drawn in, cord one end is fixed on the sliding sleeve, and portable cord can draw support in.

Connector between the stay is nylon cloth, nylon wire or canvas.

Pull bar is a tubular structure, and its tail end internal chamber wall is provided with the screw thread that is connected with standby bar spiral.

The tail end of pull bar is provided with the annulus that is connected with twisted rope on the standby twisted axis.

For forcing support to open, be provided with duck eye at pull bar by on the top end tube wall, a cord one end is fixed on the sliding sleeve, and the other end passes the tail end of duck eye exposure at pull bar.

Effect of the present utility model is: 1, adaptability is strong; not only can be used for rescuing the people in the well of big pit shaft; more be applicable in the well of little pit shaft (its diameter is less than the width of a person) and rescue the people; this is that mainly support can draw in or open; when under human body is stuck in situation in the pit shaft, suing and labouring; earlier support is drawn in; again with the leading portion of this device below the slit of the falling man's health and the borehole wall is inserted into human body; unclamp cord; support opens under the gravity effect automatically; by last lifting rod, can rescue the people.2, security is good, and this mainly is, one, and this device is made of high-intensity material, phenomenon such as do not have fracture, come off; Its two, support is rescued the people and is arranged in support as a umbrella that falls support, is blocked by stay, the outer situation of support can not occur rolling out.

Below in conjunction with embodiment and accompanying drawing the utility model is further set forth:

Description of drawings:

Accompanying drawing 1 is the structure cut-away view of the utility model embodiment 1;

Accompanying drawing 2 is the structure enlarged drawing (partial cutaway is shown) at pull bar B place in the accompanying drawing 1;

Accompanying drawing 3 is the structure partial cut-away view of the utility model embodiment 2.

The specific embodiment:

Embodiment 1, and referring to accompanying drawing 1,2, pull bar 1 can be made of steel pipe, alloy aluminum pipe, High strength plastic pipe etc.End ring 2 is fixed on the front end (below be before, the top is a tail) of pull bar 1, but its spiral be connected and fixed also can bravely connect fixing.Sliding sleeve 3 is enclosed within the pull bar 1.Stay 4 (its radical is determined by a design) end activity is fixed on the end ring 2.Lattice framing 5 (its radical is corresponding with stay a 4) end activity is fixed on the sliding sleeve 3, and other end activity is fixed on the middle part of stay 4.End ring 2, stay 4, lattice framing 5 and sliding sleeve 3 together constitute a support.Support can open or draws in along pull bar 1, with the structural similarity of umbrella.Be provided with the connector (not shown) that similar materials such as nylon cloth, nylon wire, canvas constitute between the stay 4.Sliding sleeve 3 is provided with end cord fixed thereon 6, and its function is to draw in support.Portable cord 6 can draw support in.The inner tubal wall of pull bar 1 afterbody is provided with screw thread, connects auxiliary rod when its function is the not enough well depth of pull bar 1 length, and auxiliary rod can be many.Stay 4, lattice framing 5 are manufactured by high-strength material.

Embodiment 2, and referring to accompanying drawing 3, end ring 2 is fixed on the front end of pull bar 1, and sliding sleeve 3 is enclosed within the pull bar 1.Stay 4 one end activities are fixed on the end ring 2.Lattice framing 5 one end activities are fixed on the sliding sleeve 3, and other end activity is fixed on the middle part of stay 4.Be provided with the connector (not shown) that similar materials such as nylon cloth, nylon wire, canvas constitute between the stay 4.Pull bar 1 breech face is provided with an annulus 7, and the termination of the twisted rope 9 on the twisted axis 8 is connected with annulus 7.It is laborsaving when the function of twisted axis 8 is to sue and labour.Be provided with duck eye (not drawing) at pull bar 1 by on the top end tube wall, one cord (a not drawing) end is fixed on the sliding sleeve 3, and the other end passes the tail end of duck eye exposure at pull bar 1, and its function is, when support can not open under the gravity effect automatically, force support is opened by this cord.
