Description

Hydraulically powered volume expansions device
Technical field
The present invention relates to small rescue facility, specifically a kind of hydraulically powered volume expansions device.
Background technology
Natural calamity happens occasionally, and startling disaster scene brings huge wound to the soul of the mankind, carries out efficient rescue work and proposes new challenge to rescue facility, becomes very urgent to the demand of practicality and all very strong rescue facility of specific aim.Disaster relief scene runs into narrow gap often, and the effect of the rescue facilities such as jack, cutting machine, bull-dozer can be very limited, therefore, provides a kind of barrier-breaking device being applied to small space rescue to have urgency.
Summary of the invention
Being difficult to launch the problem of rescue for solving in small space, the object of this invention is to provide one spendable rescuing and barrier-breaking device in small space.
Hydraulically powered volume expansions device of the present invention, its power rail is parallel fixing by the fixed supporting seat being arranged on power rail end with hydraulic cylinder, front end and anterior two positions of power rail are fixed wtih two link supports seats respectively, each link supports seat is flexibly connected many connecting rods, the other end of each connecting rod is flexibly connected with barb-type expansion pawl, barb-type expansion pawl front end is barb-type expansible handgrip, barb-type expansion pawl end is flexibly connected support bar front end, support bar end is hinged on sliding sleeve, sliding sleeve hinge Y type fork, Y type fork is fixed on hydraulic cylinder piston rod.
In the present invention, preferably, fixing two the link supports seats in the front end of power rail and front portion are just the same.
Link supports seat is flexibly connected connecting rod by bolt.The other end of connecting rod is flexibly connected with barb-type expansion pawl preferably by bolt.
Preferably, many connecting rods are just the same.
Device of the present invention, its hydraulic cylinder is provided with two hydraulic oil pipes.
Fixed supporting seat and link supports seat all by welding, screw fixes, spiral is fixed or groove clamping mode is fixed on power rail, or integratedly with power rail to make.For ease of maintenance, preferably adopt detachable fixed form.
The connecting rod quantity that each link supports seat connects is 4 ~ 8; The quantity of barb-type expansion pawl and support bar is identical with the connecting rod quantity that each link supports seat connects; Many barb-type expansion pawls are just the same, and many support bars are just the same.
Consider uniform force, these connecting rods, barb-type expansion pawl and support bar are all uniformly distributed around power rail.
In the present invention, barb-type expansion pawl front end has in barb outwardly, front portion curved, and when device draws in, the front end of multiple barb-type expansion pawl is combined into barb pinnacle outwardly.When in practical application, device struts to a certain extent, and barb can play the effect stoping weight to slide.
Above barb-type expansion pawl controls its folding by hydraulic cylinder piston rod, and good stability and hydraulic cylinder can make it fixing for a long time, give rescue work sufficient rescue period.
The quantity that the present invention is equipped with barb-type expansion pawl can be selected according to specific requirement, and the versatility of part is good, easy processing and manufacturing.The each parts of device can be dismantled or clamping at any time as required, are easy to carry and carry out rescue work.
Apparatus of the present invention possess the dual-use function of clamping weight and the small gaps that swells, and structure is simple, use flexibly, are widely used, are suitable for various cracking or clamping operation working site, also can support the building etc. that may cave at any time.
Device of the present invention also overcomes the drawback of similar little deliverance apparatus.Can significant change be there is in some jaw types or the scissors mechanism angle in swollen clip process between two clamping plate, cause mechanism's discontinuity, and decrease along with the stability of the enlarging mechanism of opening, right device of the present invention is in operation process, each telescopic claw does parallel motion all the time, has been conducive to the distending to close gap and expansion.
Accompanying drawing explanation
Fig. 1 is hydraulically powered volume expansions apparatus structure schematic diagram of the present invention.
Detailed description of the invention
See Fig. 1.
Hydraulically powered volume expansions device, power rail 2 is parallel fixing by the fixed supporting seat 3 being arranged on power rail 2 end with hydraulic cylinder 1, front end and anterior two positions of power rail 2 are fixed wtih two link supports seats 4 respectively, each link supports seat 4 is flexibly connected 4 connecting rods 5, the other end of each connecting rod 5 is flexibly connected with barb-type expansion pawl 8, barb-type expansion pawl 8 front end is barb-type expansible handgrip, barb-type expansion pawl 8 end is flexibly connected support bar 9 front end, support bar 9 end is hinged on sliding sleeve 10, sliding sleeve 10 is hinged Y type fork 13, Y type fork 13 is fixed on hydraulic cylinder piston rod 14.
Two link supports seats 4 that the front end of power rail 2 and front portion are fixed are just the same.
Link supports seat 4 is flexibly connected connecting rod 5 by bolt 6.
Many connecting rods 5 are just the same.
The other end of connecting rod 5 is flexibly connected with barb-type expansion pawl 8 by bolt 7.
Hydraulic cylinder 1 is provided with two hydraulic oil pipes 15;
Fixed supporting seat 3 is fixed by welding in power rail 2 end.
A link supports seat 4 is fixed on the front end of power rail 2 by spiral way, a link supports seat 4 is fixed on the front portion of power rail 2 by spiral way.
The quantity of barb-type expansion pawl 8 and support bar 9 is 4; 4 barb-type expansion pawls 8 are just the same, and 4 support bars 9 are also just the same.
Convenient, flexible in order to what connect, the end of support bar 9 is also equipped with hinged seat 11, and hinged seat 11 is hinged on sliding sleeve 10, also also arranges hinged seat 12 in the middle part of sliding sleeve 10, for the Y type fork 13 that is hinged.
In order to easy to connect, described link supports seat 4 is made into cross, and arranges four terminations, for connecting four connecting rods 5.
When practice, the barb-type expansion pawl 8 of apparatus of the present invention is collapsed into pinnacle, stretch in small space, drive hydraulic cylinder 1, hydraulic cylinder piston rod 14 stretches out, by driving Y type fork 13, hinge support bar 9 is thereon moved to barb-type expansion pawl 8 direction, because connecting rod 5 is connected on barb-type expansion pawl 8 by bolt 7, and one end is also connected on the cross supporting seat 4 that is fixed on power rail 2 by bolt 6, when support bar 9 moves to barb-type expansion pawl 8 direction, connecting rod 5 pawl 8 that barb-type can be expanded struts, reach the effect of the small space that swells.
Before this device puts into gap, barb-type expansion pawl 8 and power rail 2 angle are 20 degree of angles, and hydraulic cylinder piston rod 14 is in contraction state.After device is put into accurate location, workmen makes piston rod 14 stretch out by hydraulic control pump, makes four barb-type expansion pawl 8 distendings, narrow and small gap is swollen, until spalling.Each barb-type expansion pawl 8, in moving process, does parallel motion between each pawl all the time, and angular error is in allowed band, and thus stability under loading, is conducive to this device and completes distending to small gaps and expansion work.In addition, this device, by hydraulic-driven, can meet the requirement of intensive work.
