Abstract
A novel steel wire rope taper sleeve comprises at least two taper sleeve bodies, regulating nuts, gaskets, springs and heart-shaped taper sleeves. The at least two taper sleeve bodies penetrate through a rope hitch plate side by side, the springs, the gaskets and the regulating nuts are arranged on the upper side portions of the taper sleeve bodies, the lower side portions of the taper sleeve bodies are connected with the heart-shaped taper sleeves, and hydraulic gaskets are arranged between the regulating nuts and the gaskets. The hydraulic gaskets are connected with the hydraulic gaskets on other taper sleeve bodies through oil pipes to form a closed passive hydraulic system. After the hydraulic gaskets are added to the taper sleeves, due to the difference of the lengths of steel wire ropes, float heights of plungers will be caused to be different, the regulating nuts of all the taper sleeves are regulated to enable the float height of the plungers to be roughly identical, and the float height of the plungers is about 5mm to 6mm. Along with the using of an elevator, when difference exists between the elongations of the steel wire ropes, the hydraulic gasket will adjust automatically (4mm to 5mm elongation difference), when the elevator is maintained, maintenance staff can carry out regulation timely according to the float heights of the plungers, and the regulation is convenient and accurate.

Further, described hydraulic pressure pad comprises positioning retainer ring, cylinder body, plunger body, large sealing packing ring and small sealing ring; Described plunger body is that inner chamber is step-like circular tube shaped body, and described cylinder body is the circular tube shaped body with section annular channel; Described plunger body is after installing large sealing packing ring and small sealing ring, fit in cylinder body, form the cavity of an annular between described plunger body and cylinder body, between the top of described positioning retainer ring and cylinder body by being threaded, be provided with oil hole on described cylinder body, described oil hole is connected with the cavity that plunger body and cylinder body form.Be provided with two oil holes on each cylinder body.A plurality of tapered sleeve bodies are located in rope hitch plate side by side, and the oil hole of a plurality of hydraulic pressure pads is contacted mutually by oil pipe, form the hydraulic pressure shim pack that is interconnected; With other hydraulic pressure pads are connected, its another oil hole is equipped with check valve and is used for the servicing fluids force feed hydraulic pressure pad that is positioned at an end except an oil hole; The hydraulic pressure pad that is positioned at the other end with other hydraulic pressure pads are connected, is equipped with pressure switch on its another oil hole except an oil hole, is used for as the overload switch.
Further, inject appropriate hydraulic oil in described hydraulic pressure shim pack, oil mass is to be full of whole pipeline and jack-up all hydraulic pad plunger 5 to 6mm is advisable.Utilize manual pump to hydraulic pressure pad injection liquid force feed by check valve.
Further, for easy to adjust and accurate, the periphery wall of described plunger body in axial direction is provided with scale mark.
The beneficial effects of the utility model are: the one, and after the hydraulic pressure pad adds tapered sleeve, because of the steel rope difference in length, can cause the plunger levitation height inconsistent, regulate each tapered sleeve setting nut, make each plunger levitation height roughly the same, be about 5～6mm.The 2nd, along with the use of elevator, when steel rope had the difference of elongation, (difference of 4～5mm elongation) was regulated in the hydraulic die cushion sector-meeting voluntarily.The 3rd, during elevator maintain and protection, service personnel can in time be adjusted according to the plunger levitation height, and easy to adjust, accurate.
