Abstract
The invention relates to a portable spiral rescue expander, in particular to a rescue tool, belonging to the technical field of disaster prevention and rescue equipment. The expander is characterized by being provided with a spiral transmission mechanism with a large transmission ratio, convenience of manufacture and a self-locking property, and the expander is mainly composed of a lozenge mechanism and a feed screw nut pair, wherein the lozenge mechanism is formed by two symmetrical main arms of force and two connecting rods. The expander is light in weight, simple in structure, small in volume, convenient to carry, firm, durable and low in cost, can be equipped in a large quantity, and is a multifunctional easy-to-use rescue tool capable of expanding, pushing, prizing, fastening and the like. The expander also can be disassembled independently to be used as a spade or pry bar. Due to transmission of the feed screw nut pair and variability of shape of the lozenge, expansion can start from a very small distance and be gradually maximized by strong force.
Description
Technical field
Portable spiral rescue expander of the present invention belongs to the wrecking equipment technical field of taking precautions against natural calamities, specifically a kind of rescue tool.
Background technology
After 5.12 violent earthquake and cajaput violent earthquake occur, incipient rescue action, our rescue group almost be bare-handed in ruins shoulder raise one's hand and take off rescue life, be exactly to wait until afterwards that a limited number of instruments of suing and labouring showed up, complicated or other various reasons are difficult to use because of site environment, cause some rescue sites to incur loss through delay the Best Times that rescues life.
Through detailed market research, we find that there is following shortcoming in common in the market rescue tool:
1, function singleness, expensive (hydraulic tongs unit price Zai $18000, and do not comprise hydraulic power source).
2, weight is large, manufacturing process complicated (hydraulic tool is made complicated).
3, using method is complicated, needs the professional to operate.
4, propulsion source needs to be equipped with in addition (hydraulic power source needs to be equipped with in addition), otherwise can't use, and is difficult in maintenance etc.
Summary of the invention
The purpose of Portable spiral rescue expander of the present invention is exactly the problem for the heaviness that overcomes existing expander, complex structure, function singleness; Design a kind of lightweightly, simple in structure, volume is little, is easy to carry; Sturdy and durable, with low cost, can equip in enormous quantities; Be easy to use, with artificial active force, do not need other power; Rescue tool with top thing, sled thing, the several functions such as fastening.And can take apart separately, as excavating, crowbar uses, and is easy to assembly.Shape ambiguity by screw nut driving and rhombus, can realize that expansion distance is from very little, powerful expansion, and can't in time arrive at the scene when large-sized power wrecking equipment, facility, or the limited space of suing and labouring, in the time of can not using engine effectively to sue and labour, available this Manual expander is brought into play emergencing action in the very first time, reduces as far as possible personal casualty and property damage.
Portable spiral rescue expander of the present invention, it is characterized in that a kind of to have a transmitting ratio large, the expander of the spiral transmission device of easily manufactured and latching characteristics, this expander mainly is comprised of rhombus-mechanism and a pair of feed screw nut pair that two main force's arms of symmetry and two connecting rods form, specific descriptions are: by first main force's arm 1, second main force's arm 2, first connecting rod 3 and second connecting rod 4 form, first main force's arm 1 and second main force's arm 2 are the hollow triangle structure separately, and first main force's arm 1 and second main force's arm 2 are the structure that partially overlaps, first main force's arm, 1 upper end is provided with the first connecting bore K1, the head of lower end is fixed with the first alloy head 11, and the afterbody of lower end is provided with the second connecting bore K2; Second main force's arm, 2 upper ends are provided with the 3rd connecting bore K3, and the head of lower end is fixed with the second alloy head 12, and the afterbody of lower end is provided with the 4th connecting bore K4; First main force's arm 1 is connected with first connecting rod with the first pin 5 by the first connecting bore K1 connection; Second main force's arm 2 is connected with second connecting rod with the second pin 6 by the 3rd connecting bore K3 connection; First main force's arm 1 be connected main force's arm 2 afterbodys and connect with the 4th connecting bore K4 by the second connecting bore K2 with front contiguous block 7; First connecting rod 3 is connected with second connecting rod with rear contiguous block 8 connections; Such two main force's arms and two connecting rods have just formed the rhombus of a symmetry; Front contiguous block 7 is provided with the first through hole K5, and rear contiguous block 8 is provided with the second through hole K6; Screw mandrel 9 passes the first through hole K5 and the second through hole K6 on the rear contiguous block 8 and the nut 10 of screwing on the front contiguous block 7, nut 10 rotations, and it is expansible and the support weight that two main force's arms open.
Above-mentioned Portable spiral rescue expander, it is characterized in that partially overlapping when described first main force's arm 1 and second main force's arm 2 are incipient state, be angle between first connecting rod 3 and the second connecting rod 4 when being 52 ° main force's arm portion overlap, the first alloy head 11 and the second alloy head 12 contact, and the expansion scope of its described first main force's arm 1 and second main force's arm 2 is 20mm-400mm.
Above-mentioned Portable spiral rescue expander is characterized in that described the second connecting bore K2 and the 4th connecting bore K4 make the hole that is shaped as U-shaped that is beneficial to main force's arm Assembly ﹠Disassembly.
Above-mentioned Portable spiral rescue expander is characterized in that described first main force's arm 1 and second main force's arm 2 remove the rear double scoop of doing artificial excavation and use.
The advantage of Portable spiral rescue expander of the present invention is:
1, main force's arm is triangular in shape hollow, formed by Plate Welding, and two alloy heads contact when main force's arm merges, initial expansion distance is very little.Alloy head can increase structural strength and resistance to abrasion; The connecting bore that main force's arm is connected with contiguous block is made U-shaped, and is for convenience detach, can use as scoop after main force's arm removes.
2, feed screw nut's auxiliary drive gear has the characteristic of large, the easily manufactured and self-locking of transmitting ratio, just can rotating nut with manpower, thereby change tetragonal shape, the head of main force's arm can be opened, expansion object or support weight, the application force required along with opening of main force's arm also diminishes.
3, lightweight, simple in structure, volume is little, is easy to carry; Sturdy and durable, with low cost, can equip in enormous quantities; Rescue tool with top thing, sled thing, the several functions such as fastening.And can take apart separately, as scoop, crowbar uses.By the shape ambiguity of feed screw nut's auxiliary driving and rhombus, can realize expansion distance from very little, powerful expansion reaches maximum.
