Embodiment Construction

[0009] As shown in the drawings, the upper end of the rescue cage 2 is threaded to fix 3 groups of connecting rods 1, each group of connecting rods 1 is composed of multiple sections, which are fixed by threads so that the rescue cage 2 can be stretched to the bottom of the well. Rescue cage 2 is cylindrical, and support bar 12 is arranged at the upper end, and 6 vertical boards 5 are evenly fixed in the direction of cylindrical plain line. The lower end of the rescue cage 2 is hinged with 6 claw plates 7 through hinges 6 . There is a torsion spring on the hinge 6, which can make the hinge 6 and the claw plate 7 keep consistent with the direction of the vertical plate 5 when there is no external force, that is, the vertical state, such as figure 1 shown. The lower end of the claw plate 7 has a small hole 8 respectively, and a locking rope 10 is worn in the small hole 8. The locking rope 10 is wound on the winch 11 along the rescue cage 2 and the connecting rod 1, and the rota...

Abstract

The invention relates to a latch jack for the life saving in a small-bore deep well, which is particularly applicable to the salvage of people or objects falling into the small-bore deep well. The upper end of a rescue cage is detachably fixed with two to three groups of connecting rods, each group of connecting rod consists of a plurality of detachable parts so as to extend the rescuing cage into the bottom of the well, the rescue cage takes the shape of a column, the upper end of the rescue cage is provided with a support bar, three to eight erect plates are fixed along the tessellation line direction of the column, the lower end of the rescue cage is articulated with three to eight claw plates by a hinge, a torsional spring is arranged on the hinge so as to ensure that the hinge and the claw plates always keep in step with the direction of the erect plates, namely in the vertical state, when no external force is available. The lower ends of the claw plates are respectively provided with a small hole, a locking rope passes through the interior of the small hole and is winded on a capstan along the rescue cage and the connecting rods and the capstan is rotated to inwards tightening up the claw plates simultaneously by the locking rope. The latch jack of the invention has simple structure, convenient use and carrying as well as time and effort conservation during the rescue.

Description

technical field [0001] The invention relates to a small-diameter deep well life-saving salvage device, which is particularly suitable for salvaging people or objects falling into a small-diameter deep well. Background technique [0002] At present, there is no special salvage device for small-caliber deep wells. People or objects falling into them need to be dug out with an excavator to rescue them. Invention content: [0003] In order to overcome the disadvantages of the prior art, the present invention provides a small-diameter deep well rescue overhaul, which has a simple structure, is convenient to use and carry, and saves time and effort for rescue. [0004] The technical solution adopted by the present invention to solve the technical problem is: the upper end of the rescue cage is detachably fixed to 2~3 groups of connecting rods, and each group of connecting rods is composed of multiple detachable sections so that the rescue cage can be extended to the bottom of th...
