Abstract
The utility model relates to a hydraulic pressure safety coupling, its characterized in that: it includes shaft coupling (1), inserted six safe round pins in the draining hole on the circumference of shaft coupling (1), one be hollow shearing pin (2) in six safe round pins, and five be solid shutoff and sell (3), and wherein hollow shearing pin (2) and the solid shutoff outside of selling (3) all is equipped with seal assembly (4), the top of hollow shearing pin (2) and solid shutoff round pin (3) all compresses tightly through one housing pin (5), and the top of hollow shearing pin (2) and solid shutoff round pin (3) is provided with shearing ring (6), and wherein the top of hollow shearing pin (2) exceeds in shearing ring (6), and the top of solid shutoff round pin (3) is less than shearing ring (6). This kind of hydraulic pressure safety coupling does not have the condition appearance that six pins were cut simultaneously when cuting, sealed effectual, in case cut off the back, the time of resuming production is accelerated.
Description
Technical field
The utility model relates to a kind of hydraulic safety coupling.
Background technique
On steel rolling production-line; the coupling that rolling mill main motor is connected with speed reducer has multiple; wherein one uses more hydrocoupling, can play overload protective function, as Fig. 3 to speed reducer; its principle is exactly when actual rolling load distance exceedes the rated moment of its transmission (when overloading); safety pin on coupling will all be cut off moment, and pressure sheds, and loses carry-over moment effect; thus safety protection effect is played to main gear reducer, but have following shortcoming when it uses:
1, safety pin arranges on the high side, coupling circumferentially have six safety pins, as long as overload, produce and shear, will be cut off for six simultaneously;
2 once after safety pin cuts off, six safety pins will recover one by one, and Recovery time reaches more than one hour, larger to Influence of production;
3, safety pin is from threaded and outer-hexagonal, and the material due to safety pin is copper, and screw thread especially easily damages, and outer-hexagonal stressed after, be easy to twist distortion, not easily seal up;
4, safety pin maintenance difficulties is in the past large, and spare part consumption is large simultaneously.
Summary of the invention
The utility model is to overcome above-mentioned deficiency, provides a kind of pin to be occurred by the situation of cutting off, good sealing effect simultaneously, the hydraulic safety coupling that the time of resuming production accelerates.
The purpose of this utility model is achieved in that
A kind of hydraulic safety coupling, it comprises coupling, six safety pins are inserted with in the oil leak hole circumferentially of described coupling, in six safety pins, one is hollow shear pin, five is solid shutoff pin, the outside of its hollow core shear pin and solid shutoff pin is equipped with black box, the top of described hollow shear pin and solid shutoff pin is all compressed by a housing pin, the top of hollow shear pin and solid shutoff pin is provided with shearing ring, the top of its hollow core shear pin is above shearing ring, and the top of solid shutoff pin is lower than shearing ring.
The beneficial effects of the utility model are:
1, after adopting solid shutoff pin shutoff five oil leak hole, during shearing, six pins would not be had to be occurred by the situation of cutting off simultaneously;
2, housing pin adopts 45 steel materials, should not twist bad, easily tighten, good sealing effect;
3, once after cutting off, only need recover a pin, and the time of resuming production accelerates, and time of consumption only has original 1/6th.
Accompanying drawing explanation
Fig. 1 is the sectional arrangement drawing of the utility model a kind of hydraulic safety coupling hollow core shear pin and coupling.
Fig. 2 is the sectional arrangement drawing of solid shutoff pin and coupling in a kind of hydraulic safety coupling of the utility model.
Fig. 3 is the sectional view of hydrocoupling in the past.
Wherein: coupling 1, hollow shear pin 2, solid shutoff pin 3, black box 4, housing pin 5, shearing ring 6.
Embodiment
See Fig. 1 and Fig. 2, the utility model relates to a kind of hydraulic safety coupling, comprise coupling 1, six safety pins are inserted with in the oil leak hole circumferentially of described coupling 1, in six safety pins, one is hollow shear pin 2, five is solid shutoff pin 3, the outside of its hollow core shear pin 2 and solid shutoff pin 3 is equipped with black box 4, for improving the sealing of itself and coupling 1, the top of described hollow shear pin 2 and solid shutoff pin 3 is all compressed by a housing pin 5, the top of hollow shear pin 2 and solid shutoff pin 3 is provided with shearing ring 6, the top of its hollow core shear pin 2 is above shearing ring 6, and the top of solid shutoff pin 3 is lower than shearing ring 6.
Hollow shear pin 2 and solid shutoff pin 3 change two split parts by one into from threaded and single piece that is outer-hexagonal, jointly be made up of not threaded hollow shear pin 2 or solid shutoff pin 3 and housing pin 5, hollow shear pin 2 and solid shutoff pin 3 are still copper material, and housing pin 5 is 45 after quenching with Subsequent tempering
#steel, compress pin with the housing pin 5 of steel, pin is not fragile, improves sealing effect.
In this hydraulic safety coupling, solid shutoff pin 3 plays plugging action, hollow shear pin 2 shear actions, and milling train is once overload, and hollow shear pin 2 cuts off by shearing ring 6, pressure venting, and transmission stops, and serves overload protective function to speed reducer.
