In the present invention, preferably, the front end of power rail and anterior two fixing link supports seats are just the same.
Link supports seat is flexibly connected connecting rod by bolt.The other end of connecting rod is preferably flexibly connected with barb-type expansion pawl 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 fixes or groove clamping mode is fixed on power rail, or with the integrated making of power rail.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 stressed evenly, 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 barb, front portion outwardly interior curved, and in the time that device draws in, the front end of multiple barb-type expansion pawls is combined into barb pinnacle outwardly.When in practical application, device struts to a certain extent, and barb can play the effect that stops weight to slide.
Above barb-type expansion pawl is by its folding of hydraulic cylinder piston rod control, and good stability and hydraulic cylinder can make it fixing for a long time, succour the time fully to rescue work.
The present invention is equipped with the quantity of barb-type expansion pawl and can selectes according to specific requirement, and the versatility of part is good, easily processing and manufacturing.Installing each parts can dismantle or clamping at any time as required, is easy to carry and carries out rescue work.
Apparatus of the present invention possess clamping weight and the dual-use function in narrow and small gap of swelling, and simple in structure, use flexibly, are widely used, and are suitable for variously cracking or clamping work operations scene, also can support the building that may cave at any time etc.
Device of the present invention has also overcome the drawback of similar little deliverance apparatus.Can there is significant change in some jaw types or the scissors mechanism angle between two clamping plate in swollen clip process, cause mechanism's discontinuity, and the stability that is accompanied by the enlarging mechanism of opening decreases, right device of the present invention is in operation process, each telescopic claw is done parallel motion all the time, has been conducive to distending and expansion to close gap.
Accompanying drawing explanation
Fig. 1 is hydraulically powered space of the present invention expansion gear structural representation.
The specific embodiment
See Fig. 1.
Hydraulically powered space expansion gear, power rail 2 and hydraulic cylinder 1 are parallel fixing by being arranged on the fixed supporting seat 3 of power rail 2 ends, the front end of power rail 2 and anterior two positions are fixed wtih respectively two link supports seats 4, 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 ends are barb-type expansible handgrip, barb-type expansion pawl 8 ends are flexibly connected support bar 9 front ends, support bar 9 ends are hinged on sliding sleeve 10, sliding sleeve 10 hinge Y type forks 13, Y type fork 13 is fixed on hydraulic cylinder piston rod 14.
The front end of power rail 2 and anterior two fixing link supports seats 4 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 ends.
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 for 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, and sliding sleeve 10 middle parts also also arrange hinged seat 12, for the Y type fork 13 that is hinged.
For easy to connect, described link supports seat 4 is made into cross, and four terminations are set, for connecting four connecting rods 5.
In the time of 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, make the support bar 9 being hinged thereon to the 8 direction motions of barb-type expansion pawl, because connecting rod 5 is to be connected on barb-type expansion pawl 8 by bolt 7, and one end is also connected on the cross supporting seat 4 being fixed on power rail 2 by bolt 6, in the time that support bar 9 moves to barb-type expansion pawl 8 directions, connecting rod 5 pawl 8 that barb-type can be expanded struts, reach the effect of the small space that swells.
Before this device is put into gap, barb-type expansion pawl 8 is 20 degree angles with power rail 2 angles, and hydraulic cylinder piston rod 14 is in contraction state.After device is put into accurate location, workmen stretches out piston rod 14 by controlling hydraulic 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 all the time between each pawl, angular error is in allowed band, thereby stability under loading, is conducive to this device and completes distending and the expansion work to narrow and small gap.In addition, this device, by hydraulic-driven, can meet the requirement of intensive work.
