Description
Technical field
The present invention relates to a kind of rescue aid, be specifically related to a kind of obstruction removal rescue equipment for mines that is used under the environment such as colliery landslide.
Background technology
China is big coal country, and disaster accidents such as down-hole landslide frequently take place, and disaster accident harm is serious, and the injury personnel are many, and the breaks in production time is long, damage well lane engineering or production equipment.According to the authoritative department statistics, China's coal-mine (comprising state-owned emphasis colliery, state-run colliery, Township Coal Mine, individual colliery an etc.) year death toll accounts for more than 2/3rds of world's coal mining accident year death toll.The general important informations such as general location, existence situation and surrounding environment that adopt life detection equipment and monitoring harmful gases device etc. to obtain the devastated trapped personnel in back take place in accident, but can't directly rescue timely and effectively indicator of trapped personnel.
Present rescue mode mostly is manually, engineering machinery is excavated or disaster relief rig boring provisions.The general work amount is very big when adopt excavating rescue, and easily once more landslide cause the secondary injury, make slow progress; General coal mine roadway all more than rice, when adopting disaster relief rig boring rescue, is difficult to accurately be bored into assigned address, inefficiency apart from ground; These rescue modes all are difficult to satisfy the actual requirement of emergency relief.
Summary of the invention
Volume purpose of the present invention is to overcome deficiency of the prior art and the obstruction removal rescue equipment for mines that a kind of no-spark, handling safety is provided, can overcomes big resistance, can directly rescue timely and effectively.
The object of the present invention is achieved like this: this equipment is by rear box, loam cake, preceding casing and fluid pressure drive device are formed, wherein the afterbody activity of preceding casing is plugged on rear box inside, and between the bottom of preceding casing and rear box, be hinged with the back hydraulic cylinder, the head of casing is provided with wedge-formed incision simultaneously, on be movably arranged on the preceding casing of wedge-formed incision upper edge, hydraulic cylinder before preceding bottom half is hinged with three groups side by side, the other end of hydraulic cylinder and three bilateral toggle force-increasing mechanisms are hinged respectively before three groups, three bilateral toggle force-increasing mechanisms are all hinged with loam cake and preceding casing, back hydraulic cylinder all is connected back hydraulic cylinder with three groups of preceding hydraulic cylinders with hydraulic power unit by hydraulic line, hydraulic cylinder before three groups, hydraulic line and hydraulic power unit are formed fluid pressure drive device jointly.
Described three bilateral toggle force-increasing mechanisms are formed by upper hinge and play hinge, wherein are provided with guide groove with the hinged upper hinge of the hydraulic cylinder in centre position, and upper hinge is hinged with loam cake and preceding casing respectively with following hinge.
Described rear box, loam cake, preceding box outer surface are provided with hangnail.
Described hangnail cross section be shaped as right-angled triangle.
The present invention has following advantage: this equipment no-spark, essential safety can overcome bigger resistance, the work under the inflammable and explosive environment such as suitable colliery.With hydraulic pressure is power, and progression is imitative inchworm motion mechanism, and front and back two parts support each other; Adopt the expansion force-increasing mechanism simultaneously, when obstacle can't be hidden, remove barriers, enter inner flexible the moving ahead of ruins landslide, under the environment of colliery landslide, can overcome general rescue mode deficiency, directly rescue timely and effectively, have very strong actual application value.

The specific embodiment
As Fig. 1,2,3, shown in 4, the present invention is by rear box 1, loam cake 2, preceding casing 4 and fluid pressure drive device are formed, the afterbody activity of wherein preceding casing 4 is plugged on rear box 1 inside, and between the bottom of preceding casing 4 and rear box 1, be hinged with back hydraulic cylinder 9, the head of casing 4 is provided with wedge-formed incision 11 simultaneously, loam cake 2 is movably arranged on the preceding casing 4 of wedge-formed incision 11 upper edges, hydraulic cylinder 3 before preceding casing 4 bottoms are hinged with three groups side by side, the other end of hydraulic cylinder 3 and three bilateral toggle force-increasing mechanisms are hinged respectively before three groups, three bilateral toggle force-increasing mechanisms are all hinged with loam cake 2 and preceding casing 4, back hydraulic cylinder 9 all is connected back hydraulic cylinder 9 with three groups of preceding hydraulic cylinders 3 with hydraulic power unit by hydraulic line, hydraulic cylinder 3 before three groups, hydraulic line and hydraulic power unit are formed fluid pressure drive device jointly.
Described three bilateral toggle force-increasing mechanisms are formed by upper hinge 8 and play hinge 6, wherein are provided with guide groove 12 with the hinged upper hinge 8 of the hydraulic cylinder in centre position, and upper hinge 8 is hinged with loam cake 2 and preceding casing 4 respectively with following hinge 6.
Described rear box 1, loam cake 2, preceding casing 4 external surfaces are provided with hangnail 10.
Described hangnail 10 cross sections be shaped as right-angled triangle.
Adopting between preceding casing 4 and the rear box 1 to be slidingly connected, is driving force with hydraulic pressure, reaches the flexible purpose that moves ahead of forward and backward casing by the action back and forth of hydraulic cylinder and the orientation of hangnail.The imitative inchworm motion mechanism of this structure utilization, front and back two parts two parts support each other, adopt directed self-locking structure simultaneously, and for example the hangnail hangnail is one of the simplest form of expression of directed self-locking structure, and coordinative role reaches the flexible purpose that moves ahead.
Before be driving force between casing 4 and the upper cover plate 2 with hydraulic pressure, adopt the classification force-increasing mechanism, the extensional motion by upper cover plate 2 reaches brokenly the purpose that hinders.Wherein, the classification force-increasing mechanism reduces α by two general bilateral toggle force-increasing mechanisms and a band guide groove, and the bilateral toggle force-increasing mechanism that increases initial power output is formed.
The toggle force-increasing mechanism is bionical in the mankind's elbow joint, has the advantages that friction loss is little, the reinforcement coefficient is big, flexible, and mechanism is simple, and easy to manufacture, cost of production is lower, helps wide popularization and application.As shown in Figure 5, be F when importing thrust
iThe time, by setting up simple mathematics model, calculate and can calculate by theory:
The effect of classification force-increasing mechanism: after force-increasing mechanism was started working, α contended decrescence little, by
, under the situation that the toggle strength of materials allows, its power that can bear will increase gradually.
The top of upper hinge 8 is fixed, and the bottom of following hinge 6 is fixed, and the afterbody of hydraulic cylinder 3 is fixed; During hydraulic cylinder works, the top that the hydraulic stem promotion was in the following hinge of upper hinge groove limit inferior point 5 originally arrives upper hinge groove limes superiors point 7, calculates and can get according to the theory of above bilateral toggle force-increasing mechanism
Can increase the length difference of initial total power output groove because α reduces this moment, increases the multiple difference, determine best reinforcement coefficient according to the each side factor.
