Abstract
The invention discloses a kind of hydraulic puller which adopts to apply pretension to tight wire in the construction of single layer tight wire point-support glass wall. And the character lies in: it is a sealed stretching resistance system which is formed by a tension rod and a strength pole; a main cylinder is set in the system to realize the pretension by pulling the lever swinging. When applying pretension to tight wire, the hydraulic pressure value in the sealed system is shown by the pressure gauge; so we know the pretension value applied to the tight wire. The hydraulic puller can apply pretension to macroscopic tight wire because of the using of hydro cylinder.
Description
The present invention relates to a kind of hardware ﹠ tools, more particularly, relate to a kind of hydraulic tensioning device, belong to the hardware ﹠ tools in the building operations.
Utilize curtain wall to make the peripheral protective of building, be widely adopted in the world today.But adopt the individual layer cable wire to make the point type glass curtain wall of force structure, just entered the discussion stage in China, because run into a more complicated problem when implementing in the individual layer cable wire point-supporting glass curtain wall stretch-draw cable wire, promptly pretension how to apply and the value of applying what are can not accurately determine.
Solution to the problems described above is at present: use torque spanner to extrapolate the pretension value indirectly when the stretch-draw cable wire, but calculate that in this way the pretension value of coming out is very inaccurate, though if the follow-up tensile stress instrument that re-uses is measured accurately, workload increases gets half the result with twice the effort.Moreover rope diameter surpasses 25 millimeters, applies the pretension value with said method and can't realize at all.
Purpose of the present invention will provide a kind of lever hydraulic tensioning device exactly.Because this tensioner carries out pretension by hydraulic transmission principle to cable wire, so the size of stretch-draw rope diameter is all adapted to, pre-stretching force value also can accurately reflect.
The present invention is achieved in that outside needs apply the adjustment end of cable wire of pretension and puts the hydraulic tensioning device, main hydraulic cylinder to tensioner provides pressure liquid then, make the piston of main hydraulic cylinder stretch out the promotion lever swing, the swing process of this lever applies the pretension process to cable wire exactly.Cable wire is being applied in the process of pretension, observing the pressure gauge of the pressure liquid that main hydraulic cylinder is provided, just can accurately know the pretension value that cable wire is applied.
Lever hydraulic tensioning device among the present invention, it is characterized in that by a pull bar, the pressure system that the power post is formed, a main hydraulic cylinder promotion lever swing of configuration symmetry is realized cable wire is applied pretension in this system, cable wire is being carried out to pass through to observe the hydraulic pressures table in the pretension process, just can accurately know the pretension value that is subjected to prestretched strand, because this tensioner adopts hydraulic actuation power, so can apply pretension to large-scale cable wire.
Concrete structure of the present invention is provided by following examples and accompanying drawing.
Accompanying drawing is the structure and the fundamental diagram of the lever hydraulic tensioning device of proposition according to the present invention.
Describe the textural association and the operating principle of the concrete lever hydraulic tensioning device that proposes according to the present invention in detail below in conjunction with accompanying drawing: accompanying drawing is the structure chart of lever hydraulic tensioning device, A-A figure is a part sectioned view, and this sectional drawing is the matching relationships of the several parts of expression at horizontal level.Lever hydraulic tensioning device among this figure is in duty.Introduce the assembly relation between the component of lever hydraulic tensioning device below, with two of cable wire 3 fixedly termination 1 be installed between ground 01 and the floor 02, the cable wire of installing 3 relaxes, must apply certain stretching force to it collapses tightly it, at this moment the draw-in groove of the seat board 4 of lever hydraulic tensioning device is fixed on fixedly on the termination 1, the draw-in groove of the lever 11 of lever hydraulic tensioning device is fixed on the top that has adjuster 2 of cable wire 3, regulate two and adjust thread bush 7, make lever 6 and power post 5 be in the initial stressed state, provide pressure liquid by 8 pairs of main hydraulic cylinders 9 of hydraulic pump then, make the piston of main hydraulic cylinder 9 stretch out promotion lever 11 to lower swing, these lever 11 swing process apply the pretension process to cable wire 3 exactly, the pressure values that the pressure gauge 10 of the pressure liquid that observation provides main hydraulic cylinder 9 reflects above just can accurately be known the pretension value that cable wire 3 is applied.The operator applies in the process of pretension at the above-mentioned lever tensioner of operation to cable wire 3, the slowly rotation regulator 2 that will not stop according to the swing speed of lever 11, finish up to applying pretension, tighten the hold-doun nut at adjuster 2 two ends then, last unloading pressure liquid takes off lever hydraulic tensioning device.
Claims (1)
1. lever hydraulic tensioning device, the pressure system that it is made up of pull bar 6, power post 5, disposed a main hydraulic cylinder 9 in above-mentioned pressure system, it can promote lever 11 and swing back and forth, and it is characterized in that tensioning cable mechanism is made up of lever 11 and main hydraulic cylinder 9.
