Abstract
The invention discloses a portable rescuing device with shearing, expanding and supporting functions, and relates to the technical field of rescuing devices. The portable rescuing device with the shearing, expanding and supporting functions comprises a scissor-type jack, wherein a set of scissor device is arranged at the extending end of a leading screw of the scissor-type jack; the scissor device comprises two scissor heads which are matched with each other, a scissor handle which is connected with the scissor heads, and a connecting device; the scissor heads are fixed at the extending end of the leading screw of the scissor-type jack; and the two scissor heads are installed on a corresponding connecting rod on one side of the scissor-type jack through the scissor head respectively. The portable rescuing device with the shearing, expanding and supporting functions has the advantages as follows: a four-connecting rod mechanism of the scissor-type jack is a force-saving mechanism; the shearing, expanding and supporting functions can be realized by relatively small force; the scissor-type jack and the attached scissor heads are small in volume and convenient to carry; the operation in a narrow space is convenient; and the rescue is convenient.
Description
Technical field
The present invention relates to the deliverance apparatus technical field, specifically is that a kind of portable cutting expanded the support deliverance apparatus; Be mainly used in the disaster relief scene, especially be applied to the rescue site of operation field complicacy and operation field limited space.
Background technology
Rescue site also must have small-sized deliverance apparatus except large-scale rescue aid will be arranged, and deliverance apparatus should possess multiple function.Existing existing small-sized deliverance apparatus has hydraulic pressure class and mechanical two kinds.The small-sized deliverance apparatus of hydraulic pressure class includes hydraulic pressure and cuts expansion device, hydraulic jack etc., and mechanical small-sized deliverance apparatus has various mechanic jacks, mechanical scissor etc.
The advantage of the small-sized deliverance apparatus of hydraulic pressure class is the driving force that can provide bigger; But the rescue function is comparatively single; As the jack that can only accomplish the valency bracing or strutting arrangement with cut enlarging device cut the expansion device, the product of hydraulic pressure class also exists and costs an arm and a leg and problem such as hydraulic fluid leak simultaneously.
The advantage of mechanical small-sized deliverance apparatus is that price is comparatively cheap with respect to hydraulic product; And it is safe and reliable; There are not problems such as hydraulic fluid leak; But pure mechanical deliverance apparatus does not also have the product of the unification of multiple function at present, can not realize supporting, shear and function such as expansion deposit deliverance apparatus.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; The present invention provides a kind of portable cutting to expand the support deliverance apparatus; The pure mechanical deliverance apparatus of one is cut, expands, is supported for to this device collection; Both overcome the intrinsic shortcoming of hydraulic pressure class, replenished mechanical deficiency simultaneously again, as effectively replenishing between main equipment and the manpower rescue.
The present invention realizes with following technical scheme: a kind of portable cutting expanded the support deliverance apparatus, comprises a scissor jack; External part at scissor jack leading screw increases by a cover scissors apparatus; Described scissors apparatus comprises two cutter heads that match, handle of a knife that is connected with cutter head and jockey; Cutter head is fixed on the external part of scissor jack leading screw through jockey; Two cutter heads are installed on the corresponding connecting rod of scissor jack one side through a handle of a knife respectively.
The invention has the beneficial effects as follows: the quadric chain of scissor jack is an effort-saving mechanism, can realize cutting with less power, expansion and support function; Scissor jack and the cutter head volume that adds are less, are easy to carry, and also are convenient to can carry out operation at narrow space, are convenient to rescue.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the jockey structural representation.
Among the figure: 1, scissor jack, 11, connecting rod, 12, screw mandrel, 2, scissors apparatus; 21, cutter head, 22, jockey, 221, connecting rod, 222, the connecting rod pedestal; 223, cutter head fixture, 224, taper roll bearing, 225, reverse duplex bearing overcoat mechanism, 226, two threaded connection.
The specific embodiment
As shown in Figure 1, the portable expansion support deliverance apparatus of cutting has a scissor jack 1; External part at scissor jack leading screw 12 increases by a cover scissors apparatus 2; Described scissors apparatus 2 comprises two cutter heads that match 21, the handle of a knife 23 and the jockey 22 that are connected with cutter head 21; Cutter head 21 is fixed on the external part of scissor jack leading screw 12 through jockey 22; Two cutter heads are installed on the corresponding connecting rod 11 of scissor jack one side through a handle of a knife respectively.
As shown in Figure 2, jockey 22 comprises connecting rod 221 that a cutter head connects, be installed in connecting rod pedestal 222 on the connecting rod 221, be installed in cutter head fixture 223 on the connecting rod pedestal 222, be installed in the reverse duplex bearing overcoat mechanism 225 on the cutter head fixture 223, the reverse duplex bearing overcoat mechanism 225 a pair of taper roll bearing 224 and two threaded connections 226 are installed.Through two threaded connections 226 scissor jack leading screw 12 is linked together with cutter head 21.
The course of work: the other end at scissor jack leading screw increases by a cover scissors apparatus; The tie point of cutter head is fixed on the top of leading screw; Handle of a knife is fixed on the connecting rod of scissor jack one side, and when rotating the nut of scissor jack, the connecting rod of scissor jack can be expanded or shrink; And also movement therewith of the handle of a knife on the connecting rod, thereby drive the cutter head expansion or shear.
The present invention has a extensive future, and multiple motor functions such as shearing, expansion, support can be provided, and both can be applicable to the field rescue of disaster; Can be used for general purpose tool by general family again uses; Usefulness, light small and exquisite, with low cost more than one is for general family can bear.The present invention is simple in structure, be convenient to safeguard that general individual, enterprise all can produce that make, the approach of practical implementation can be through interested producer Joint Production.
