Description
Technical field
The utility model relates to a kind of elevator.
Background technology
Existing elevator generally all has counterweight, and the elevator of counterweight is arranged, and elevator motor need drive counterweight and car simultaneously, so power consumption is big; For this reason, people research and develop hardy, hope a kind of elevator without counterweight of invention; But, up to the present, also do not have a kind of 5 counterweight elevators of maturation.
Summary of the invention
The goal of the invention of the utility model is to provide a kind of maturation, failure-free non-counterweight elevator.
The utility model is to realize like this; Comprise motor, traction wheels, car, hoist ropes; It is characterized in that the traction wheels comprise first traction sheave that directly drives by motor, with second traction sheave, the 3rd traction sheave, the 4th traction sheave, the 5th traction sheave of first traction sheave pairing; Second traction sheave be positioned at first traction sheave below; The 4th traction sheave, the 5th traction sheave are positioned at hoistway top and hoistway bottom of the building; The 3rd traction sheave is positioned at below the 4th traction sheave and is positioned between first traction sheave, second traction sheave, and after hoist ropes one end was fixed on car top and walks around the 4th traction sheave, the 3rd traction sheave, first traction sheave, second traction sheave, the 3rd traction sheave, the 5th traction sheave successively, the other end of hoist ropes was fixed on the bottom of car; Be provided with first tensioner between second traction sheave and attachment point, be provided with second tensioner between at the bottom of the 5th traction sheave and the hoistway.
During work; The loading of car is used for several steel ropes and walks around the 4th traction sheave of hoistway top successively and forward the 3rd traction sheave to; Invest first traction sheave that motor directly drives again; The rope power T2 that another side is used for the loading of balance car is provided by second traction sheave, and T2 rope is pressed and walked around the 3rd traction sheave and forward well pit again to and walk around the 5th traction sheave and return and be fixed on the car underframe, forms a balance tension netting network.
The utility model is characterised in that between direct first traction sheave that drives of motor and the 4th traction sheave has inserted one the 3rd traction sheave; The position is lower than the first traction sheave level that motor directly drives; And to move closely and be no less than 175 ° of angles to steel rope and traction sheave contact surface; The effect of the 3rd traction sheave is to press the rope of second traction sheave T2 when the 3rd traction sheave rotates, dissolve, and rope heavily strengthens and causes and skid when avoiding the car starting and since motor directly first traction sheave of drive be responsible for spurring car; Also drive simultaneously the tension of the 3rd traction sheave turning handle T2 rope power; First traction sheave that helps motor directly to drive drags car jointly and rises, and makes the quality of driven by motor often be in the no-load run situation, reaches energy-saving effect so the power that consumes is little.
Modal again potential danger is the mechanical hatching gate fault; Can not in time find and make car and slip the car accident of rushing to summit suddenly like brake shoes wearing and tearing; Would not take place in this inventive features; Because of the 3rd traction sheave is not easy to rotate by twice car loading rope power (force of inertia) locking, very safe in theory.
The active force that is caused by car load is additional to the stress T of steel rope
1Effect drag rope sheave combination and give birth to be used for the gravity of compensation balance car from external force (body force) such as gravity, centnifugal force, force of inertias; And above-mentioned external force all can be adjusted through quantity, the tension force of adjustment hoist ropes; Technology is simple, ripe, replaces traditional balance weight.Owing to there has not been counterweight, total quality of driven by motor is little, and the power that is consumed is little, and, simple on the technical know-how of the present invention, ripe, reliable.
Compared with present technology the utility model has maturation, failure-free advantage.
