Specific embodiment

For further illustrating that this utility model is to reach technological means and effect that predetermined goal of the invention is taken, below In conjunction with accompanying drawing and preferred embodiment, to according to the utility model proposes a kind of safety arrestment N-free diet method fluid path, it is embodied as Mode, structure, feature and its effect, after describing in detail such as.

A kind of safety arrestment N-free diet method fluid path includes pressure oil-source fluid path 1, changes fluid path 2, unidirectional fluid path 3, oil-filled accumulation of energy Fluid path 4, service braking/safety arrestment composite voltage regulating fluid path 5, emergent brakingby pass 6, brake group 7.Pressure oil-source fluid path 1 Outfan is connected with the input of the conversion first input end of fluid path 2 and unidirectional fluid path 3, oil-filled accumulation of energy fluid path 4 and unidirectional fluid path 3 Outfan and conversion fluid path 2 second input connect；The outfan of conversion fluid path 2 and service braking/safety arrestment are combined Pressure regulation fluid path 5, emergent brakingby pass 6 and brake group 7 connect.

Pressure oil-source fluid path 1 includes pressure oil meter 10, filter 11, motor 12, oil pump 13, overflow valve 14；Conversion fluid path 2 Including electromagnetic valve 15；Unidirectional fluid path 3 includes check valve 16；Oil-filled accumulation of energy fluid path 4 includes electromagnetic valve 15, choke valve 17, accumulator 18th, pressure controller 19 and pressure oil meter 10；Service braking/safety arrestment composite voltage regulating fluid path 5 includes pressure oil meter 10, electro-hydraulic Proportional pressure control valve 20 and radiator 23；Emergent brakingby pass 6 includes electromagnetic valve；Brake group 7 includes brake group 21 and braking Device group 22.

During specific works, in motor 12 in pressure oil-source fluid path 1 and oil pump 13 operating, provide pressure oil, through filter 11 and overflow valve 14 the pressure oil upper limit is limited, the converted fluid path of pressure oil 2 is supplied to brake group 7 as brake group Open a sluice gate and close lock control oil, oil pressure size is by the electricity liquid ratio relief valve in service braking/safety arrestment composite voltage regulating fluid path 5 20 are controlled adjusting, and pressure oil is charged into pressure oil through unidirectional fluid path 3 to oil-filled accumulation of energy fluid path 4 simultaneously, as safety arrestment Standby pressure oil sources, emergent brakingby pass 6 can be braked as system emergency and use.Weight fault occurs in elevator system work When, automatically or electrical control is transformed in oil-filled accumulation of energy fluid path 4, now pressure oil-source fluid path 1 opening pressure for conversion fluid path 2 meeting Oily service duct, and brake group 7 pressure oil is supplied to by oil-filled accumulation of energy fluid path 4, by service braking/safety arrestment composite voltage regulating Fluid path 5 automatically adjusts safety arrestment oil pressure so that the automatic constant deceleration brake oil pressure of supply brake group 7 meets given deceleration The requirement to oil pressure for the curve, emergent brakingby pass 6 ensures as emergency brake.

Safety arrestment fluid path in accompanying drawing 3 and accompanying drawing 4 is existing safety arrestment wait type fluid path, pressure oil-source fluid path 1 Pressure oil liquid is delivered to brake group 7 through conversion fluid path 2 open a sluice gate and close lock to control oil, oil pressure size is by service braking pressure regulation Electricity liquid ratio relief valve 20 in fluid path 8 is controlled adjusting, and emergent brakingby pass 6 can be braked as system emergency and use.Carrying When weight fault in liter machine system work, automatically or electrical control is transformed in oil-filled accumulation of energy fluid path 4 for conversion fluid path 2 meeting, Now pressure oil-source fluid path 1 opening pressure oil service duct, and connected by oil-filled accumulation of energy fluid path 4 and be supplied to brake group 7 pressure Oil, does automatic safe braking oil pressure by safety arrestment pressure regulation fluid path 9 and adjusts so that the oil pressure of supply brake group 7 meets deceleration Write music the requirement to oil pressure for the line, emergent brakingby pass 6 ensures as emergency brake.

Safety arrestment pressure regulation fluid path 9 in this existing liquid-way system and service braking pressure regulation fluid path 8 be divided into two different Functional device, in normal work, frequent action is service braking pressure regulation fluid path 8, and safety arrestment pressure regulation fluid path 9 be in through The static waiting state of perseverance, just because of this, components and parts electro-hydraulic servo direction valve 24 long inactivity of fluid path does not work, once needing It is likely to appearance card when starting work blunt and astringent, cause safety arrestment baulk.

Service braking in this utility model/safety arrestment composite voltage regulating fluid path 5 is that service braking adjusts fluid path and safety Braking adjusts the compound of two kinds of functions of fluid path, all can be in operating state in service braking or in safety arrestment, Namely safety arrestment no wait state, so can effectively ensure that when weight fault in elevator system, safety arrestment energy Enough enable at any time, tackle fault, support personnel and property safety to greatest extent at any time.

The above, be only preferred embodiment of the present utility model, not this utility model is made any formal Restriction although this utility model is disclosed above with preferred embodiment, but be not limited to this utility model, any ripe Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when in the technology of available the disclosure above Hold and make a little Equivalent embodiments changing or be modified to equivalent variations, as long as without departing from technical solutions of the utility model Hold, any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still Belong in the range of technical solutions of the utility model.
