Abstract
Zero load accelerates forcible entry expander, main body is made of hand control valve, oil cylinder, piston, connecting rod, supporting sleeve, expansion arm and work head, hand control valve is connected with oil cylinder, the piston tip of oil cylinder is connected by connecting rod with supporting sleeve, two expansion arms are symmetricly set on supporting sleeve front end, each expansion arm front end connects a work head, sets crushing block in the middle part of each expansion arm, connecting rod sets main pin with piston junction.Present device system pressure is up to 72MPa, can generate powerful expansionary force, and barrier is pushed in easily expansion open；Hand control valve rotates easy and flexible, easy to operate；Crushing block is equipped in the middle part of expansion arm, therefore available for squeeze job, add squeeze function；Expander work head uses quick-release connector connection structure, easy to operate, saves the time.
Description
Technical field
The present invention relates to a kind of fire-fighting and rescue instruments, and in particular to a kind of unloaded acceleration forcible entry expander.
Background technology
Forcible entry expander be fire fighter when putting out a fire or rescuing people forcibly door and window, demolition building, open up fire-fighting
Passage removes glow ember and common equipment when mopping up.Existing forcible entry expansion tool is mainly disappearing for manual operation
Anti- axe, pike pole, iron quickly take time and effort to install with insulation cutter, these instruments, and forcible entry efficiency is low, affects fire-fighting and rescue efficiency.
The content of the invention
The present invention provides a kind of unloaded acceleration forcible entry expander, to solve manual forcible entry expansion work existing in the prior art
Tool operates the problem of time-consuming and laborious influence rescue efficiency.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of unloaded acceleration forcible entry expander, main body is by hand control valve, oil cylinder, piston, connecting rod, supporting sleeve, expansion arm and work
Make head composition, hand control valve is connected with oil cylinder, and the piston tip of oil cylinder is connected by connecting rod with supporting sleeve, and two expansion arms are symmetrically set
It puts in supporting sleeve front end, each expansion arm front end connects a work head, and crushing block, connecting rod and work are set in the middle part of each expansion arm
It fills in junction and main pin is set.
Above-mentioned supporting sleeve surface sets sheath, one handle of oil cylinder external connection.
The operation principle of present device is：Using external connection hydraulic pump, liquid flow path direction is controlled by hand control valve, is utilized
Hydraulic fluid pressure is acted on piston, using the principle of F=PS, promotes piston and connecting rod, and supporting sleeve is driven to pass through two expansions
Most power is transferred on work head arm at last, is carried out expansion operation, is equipped with crushing block in the middle part of expansion arm, can also carry out squeeze job,
Add squeeze function.
Present device system pressure is up to 72MPa, can generate powerful expansionary force, and barrier is pushed in easily expansion open；
Hand control valve rotates easy and flexible, easy to operate；Crushing block is equipped in the middle part of expansion arm, therefore available for squeeze job, add extruding
Function；Expander work head uses quick-release connector connection structure, easy to operate, saves the time.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of present device.
1 work head, 2 expansion arms, 3 supporting sleeves, 4 connecting rods, 5 main pins, 6 sheaths, 7 handles, 8 pistons, 9 oil cylinders, 10 in figure
Hand control valve, 11 crushing blocks.
Specific embodiment
As shown in the figure, a kind of unloaded acceleration forcible entry expander, main body is by hand control valve 10, oil cylinder 9, piston 8, connecting rod 4, support
Set 3, expansion arm 2 and first 1 composition of work, hand control valve 10 are connected with oil cylinder 9, and 8 top of piston of oil cylinder 9 passes through connecting rod 4 and support
Set 3 is connected, and two expansion arms 2 are symmetricly set on 3 front end of supporting sleeve, and each expansion arm front end connects a job first 1, Mei Gekuo
2 middle parts of stretching one's arms set crushing blocks 11, and connecting rod 4 and 8 junction of piston set main pin 5, and 3 surface of supporting sleeve sets sheath 6, oil cylinder
9 external connection handles 7.
The operation principle of present device is：Using external connection hydraulic pump, liquid flow path direction is controlled by hand control valve, is utilized
Hydraulic fluid pressure is acted on piston, using the principle of F=PS, promotes piston and connecting rod, and supporting sleeve is driven to pass through two expansions
Most power is transferred on work head arm at last, is carried out expansion operation, is equipped with crushing block in the middle part of expansion arm, can also carry out squeeze job,
Add squeeze function.
Present device system pressure is up to 72MPa, can generate powerful expansionary force, and barrier is pushed in easily expansion open；
Hand control valve rotates easy and flexible, easy to operate；Crushing block is equipped in the middle part of expansion arm, therefore available for squeeze job, add extruding
Function；Expander work head uses quick-release connector connection structure, easy to operate, saves the time.
