The utility model has the advantages that, first, the drive system of elevator is arranged in the counterweight, no resonance phenomenon is provided with the elevator car for the comfort and safety of the people; second, the balance of iron is saved, so the elevator is of low cost, low consumption of materials and energy as well as a plurality of other advantages.

Description

Counterweight drives machine-roomless lift

Technical field

The utility model belongs to machine-roomless lift, particularly relate to a kind ofly do not have that resonance, noise are little, safety and comfort and the low counterweight of cost drive machine-roomless lift.

Background technology

Present known machine-roomless lift is by being fixed on the steel cable traction of building well headroom, the counterweight body that comprise car, be used for fixing the car frame, towing machine, controller of car, is provided with the car relative equilibrium and the steel cable of traction car, described towing machine and controller are installed on car top and the car frame, this kind version has increased the weight of car, counterweight corresponding with it also must be gained in weight and just can make it keep balance simultaneously, therefore need many consumable materials, manufacturing cost height; The noise of towing machine is directly propagated in car by car top, and easy and car produces resonance and resonance phenomenon, and noise is bigger, so the elevator drive ability is had a negative impact.

Summary of the invention

The utility model for solve the technical matters that exists in the known technology provide a kind of have do not have resonance, noise is little, safety and comfort and the low counterweight of cost drive machine-roomless lift.

The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:

Counterweight drives machine-roomless lift, the dragged wire-rope of counterweight, counterweight frame and the traction car that mainly comprise car, be used for fixing the car frame, towing machine, car flogic system controller, counterweight dragging system controller of car, is provided with the car relative equilibrium is formed, in counterweight, be provided with counterweight dragging system controller, EPM planetary wheel towing machine is installed on counterweight frame, being connected with the purpose made counterweight between counterweight and the car--the car trailing cable is connected with the car trailing cable between car, cable bracket and hoistway outer controller.

The utility model can also adopt following technical measures:

Described dragged wire-rope one end is fixed on the counterweight fag end of hoistway upper end bearing beam, the sagging traction rope sheave of walking around, go up again around to leading sheave, sagging two diversion sheaves walking around the car bottom, the up car fag end that is fixed in, the car fag end is fixed on the bearing beam, and car and counterweight are coupled together by dragged wire-rope, become interactive relationship, finish the traction driving by the towing machine that is installed on the counterweight.

Also be provided with automatic emergency deliverance apparatus, emergency source of electrical power, power consumption resistance box and standby dry battery power on the described counterweight frame.

Described car top is provided with mechanical gripping means, governor rope fixing device, special-purpose suspension attachment and guard rail, safety tongs at the bottom of bottom the car sedan-chair being installed, and governor rope is captiveed joint with car.

Described trailing cable is comprising power lead that main power source power supply power is arranged and transmission signal wires.

Described cable bracket and hoistway outer controller are fixed on the well enclosure, and trailing cable is fixedly connected on the cable bracket, and trailing cable is sagging and be connected with car.

Advantage and the good effect that the utlity model has are: because the dragging system of this elevator is mounted on the counterweight, one can not produce resonance, resonance phenomenon to car, people is felt comfortably cool, safety when taking elevator; Its two, can save the balance iron of counterweight equivalent weight, so have plurality of advantages such as low cost of manufacture, consumable material be low, energy-conservation.
