Abstract
Hydraulic door opener, it is made up of oil cylinder, bound feet and big foot, oil cylinder is connected by snap joint with power source, the pistons end of oil cylinder is connected with bound feet, hydraulic cylinder bottom is connected with big foot, big foot bottom connects a L-shaped lifter board, L-shaped lifter board has wedge-shaped table top, big foot side sets handle, Y type rubber seal rings for seal is used between oil cylinder and internal piston, lip sets guide sleeve and circlip respectively towards pressure oil side, Y type rubber seal bottoms and top, and piston is acted on by extension spring to be resetted.The sealed coupling face that the present invention is carried out using Y types rubber seal between oil cylinder and piston seals, conventional hydraulic door opener is solved using the resistance of O-ring seal and Glais ring greatly with standing leakage problems, in the bottom of oil cylinder, handle is set, increase device security, personnel's fixed equipment easy to operation simultaneously, big bound feet working face is equipped with anti-slop serrations, is easy to hold and fixes and is expanded object.
Description
Technical field
The present invention relates to a kind of fire-fighting and rescue instrument, and in particular to a kind of hydraulic door opener.
Background technology
Practical problem existing for the hydraulic door opener rescue product that currently there are：Using the hydraulic pressure of two-way cylinder
Door opener：The folding of door opener is required for hydraulic oil to be promoted, cause door opener itself increase reversing arrangement and it is complicated,
Weight increase；It is cumbersome and inconvenient because needing to commutate during operation；Using the hydraulic door opener of one-way cylinder：Between piston and oil cylinder
Sealed using O-ring seal, require that O-ring seal decrement is big because system pressure is up to 63MPa, during cooperation, cause piston to be transported
Frictional force increases when dynamic, and piston leans on spring reset after the completion of work, and reset speed is slow；Hole lattice Lay is used between piston and oil cylinder
Circle sealing, frictional force is small during piston movement, but lattice are poor to enclose sealing effectiveness during low pressure, causes door opener easy seepage when standing；
Existing door opener operating personnel's oil cylinder directly dominated by hand during operation, easily occurs quick-fried in case of high pressures without handle
Cylinder, the situation for injuring personnel.
The content of the invention
It is complicated existing for prior art to solve the invention provides a kind of hydraulic door opener, it is living after the completion of work
When plug resets slow and standing the problem of easy seepage.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of hydraulic door opener, it is made up of oil cylinder, bound feet and big foot, oil cylinder is connected by snap joint with power source, oil cylinder
Pistons end is connected with bound feet, and hydraulic cylinder bottom is connected with big foot, and big foot bottom connects a L-shaped lifter board, L-shaped lifter board
With wedge-shaped table top, big foot side sets handle, uses Y type rubber seal rings for seal between oil cylinder and internal piston, lip to
Pressure oil side, Y type rubber seal bottoms and top set guide sleeve and circlip respectively, and piston acts on multiple by extension spring
Position.
It is fixed at the top of above-mentioned extension spring by extension spring steady pin on oil cylinder inner wall.
Above-mentioned small foot bottom sets anti-slop serrations.
Present device presses oil in use, after connected pipes through hydraulic pump feed flow, and piston stretches out, the large and small pin work of door opener
Make face to separate the shop front with doorframe, distance continues to increase, and separating distance maximum can be to 260mm, so as to reach the mesh for rescue of opening the door
, after the completion of enabling operation, hydraulic fluid pressure is discharged, piston is just reset to reset condition in the presence of back-moving spring.
The present invention uses one-way cylinder, can reduce system pressure to 50MPa, oil cylinder is carried out using Y types rubber seal
Sealed coupling face sealing between piston, the resistance for solving conventional hydraulic door opener using O-ring seal and Glais ring are big
With standing leakage problems, handle is set in the bottom of oil cylinder, increases device security, while personnel's fixed equipment easy to operation,
Big bound feet working face is equipped with anti-slop serrations, is easy to hold and fixes and is expanded object.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of present device；
Fig. 2 is the view that present device piston is withdrawn；
Fig. 3 is oil cylinder internal structure schematic diagram of the present invention.
1 oil cylinder, 2 pistons, 3 bound feets, 4 big feet, 5L shapes lifter board, 6 handles, 7 anti-slop serrations, 8 snap joints, 9 are oriented in figure
Set, 10Y types rubber seal, 11 circlips, 12 extension springs, 13 extension spring steady pins.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of hydraulic door opener, it is made up of oil cylinder 1, bound feet 3 and big foot 4, oil cylinder 1 passes through
Snap joint 8 is connected with power source, and the end of piston 2 of oil cylinder 1 is connected with bound feet 3, and the bottom of bound feet 3 sets anti-slop serrations 7, oil cylinder 1
Cylinder body bottom is connected with big foot 4, and the bottom of big foot 4 connects a L-shaped lifter board 5, and L-shaped lifter board 5 has wedge-shaped table top, big foot 4
Side sets handle 6, is sealed between oil cylinder 1 and internal piston 2 using Y types rubber seal 10, and lip is towards pressure oil side, Y
The bottom of type rubber seal 10 and top set guide sleeve 9 and circlip 11 respectively, and piston 2 is acted on by extension spring 12 to be resetted,
The top of extension spring 12 is fixed on oil cylinder inner wall by extension spring steady pin 13.
Present device presses oil in use, after connected pipes through hydraulic pump feed flow, and piston stretches out, the large and small pin work of door opener
Make face to separate the shop front with doorframe, distance continues to increase, and separating distance maximum can be to 260mm, so as to reach the mesh for rescue of opening the door
, after the completion of enabling operation, hydraulic fluid pressure is discharged, piston is just reset to reset condition in the presence of back-moving spring.
