Description

Miniature reinforcing bar quick-break device

Technical field:

The utility model relates to a kind of rescue aid, more specifically says so to relate to a kind of miniature reinforcing bar quick-break of the fluid pressure type device that can use one-handed performance in small space.

Background technology:

Along with the continuous progress of society, the seriousness of disasters such as natural calamity and fire, traffic accident, industrial accident is more and more by popular cognition.In order to handle the harm that disaster accident causes to people in the daily life, the rescue aid equipment that is absolutely necessary.What traditional rescue outfit was emphasized is that function is strong, active force is big, tonnage is big, has often ignored simple to operate, light performance.Often be trapped in the narrow space in the rescue site indicator of trapped personnel, large-scale equipment is because volume can not be deep into inside greatly; Because the structure around active force can affect when orcible entry greatly, even crisis trapped person, this stays many sorry to the rescue personnel.A large amount of rescue experiences are told us: after having equipped large-scale rescue outfit, rescue tool small and exquisite, light, one-hand operation will play irreplaceable effect near the trapped person time.

The utility model content:

The utility model is to be power with hydraulic pressure, promotes piston by oil cylinder, and hydraulic coupling is transformed into cut-out power.The working head partial design of instrument becomes two relative blades, and moving cutting tool and fixed cutting tool have anti-slop serrations on the cutter.Body of tool part downside has been designed to opening, can hold the cut material body, and there is the moving cutting tool gathering sill inside, the moment of flexure when the bossed muscle balance of upside is cut off operation.Hydraulic coupling passes to piston during work, be contained in the motion of the moving cutting tool on the piston and the fixed cutting tool sheared edge that partners, can cut off reinforcing bar or light section section bar, its cut-out function can open personnel's stranded space, thereby reaches the purpose that indicator of trapped personnel is saved out from small space.Owing to adopted the above technology of hydraulic pressure super-pressure 35Mpa, the instrument that makes has big active force when less cylinder diameter; It is littler to adopt finite element optimum design, parts to use the combination of unimach and the above technology of hydraulic pressure super-pressure 35Mpa to make that the instrument overall dimensions becomes, and weight is lighter, makes rescue personnel's possibility that the one-handed performance instrument becomes in small space.

The utility model is realized by following technical proposals:

A kind of miniature rescue tool of fluid pressure type that can use one-handed performance in small space is characterized in that comprising oil cylinder, body of tool, fixed cutting tool and moving cutting tool composition.After hydraulic pump passed through the oil-in fuel feeding, hydraulic power promoted piston by oil cylinder, hydraulic coupling is transformed into the cut-out power of cutter.The working head partial design of instrument becomes two relative blades, moving cutting tool and fixed cutting tool, anti-slop serrations is arranged on the cutting edge roundness, moving cutting tool is contained on the piston rod, and fixed cutting tool is contained on the body of tool, and body of tool part downside becomes to have opening for arranging Tool Design, and can hold the cut material body, there is the moving cutting tool gathering sill body of tool inside, the bossed muscle of body of tool upside, but the moment of flexure that oil cylinder power unbalance loading forms when balance is cut off operation.Be contained in the motion of the moving cutting tool on the piston and the fixed cutting tool sheared edge that partners during work, can cut off reinforcing bar or light section section bar, its cut-out function can open personnel's stranded space, thereby reaches the purpose that indicator of trapped personnel is saved out from small space.Described oil cylinder is the above ultrahigh pressure cylinder of hydraulic pressure 35MPa, and body of tool is made by high strength alloy steel, and cutting knife is made by the superstrength alloy steel.

Description of drawings

Accompanying drawing is a schematic diagram of the present utility model

Following knot and accompanying drawing and concrete enforcement describe in detail the utility model

The miniature reinforcing bar quick-break of the utility model fluid pressure type device miniature comprising: 1 oil cylinder, 2 body of tool, 3 fixed cutting tools, 4 moving cutting tools.

Described oil cylinder 1 links to each other with an end of body of tool 2, and the piston rod of oil cylinder 1 links to each other with moving cutting tool 4, and fixed cutting tool 3 is contained on the body of tool, and body of tool is provided with the moving cutting tool gathering sill, on moving cutting tool and the fixed cutting tool cutting edge anti-slop serrations is arranged.Hydraulic pump behind the oil-in fuel feeding hydraulic coupling through piston rod promote the moving cutting tool motion and with the fixed cutting tool sheared edge that partners, can cut off reinforcing bar or light section section bar, its cut-out function can open personnel's stranded space, thereby reaches the purpose that indicator of trapped personnel is saved out from small space.

Although relate to a kind of rescue aid with reference to embodiment is disclosed, in small space with the miniature reinforcing bar quick-break of fluid pressure type of one-handed performance from device.Carried out special description.Above description be illustrative be not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all changes and revising all in scope of the present utility model.
