Abstract

The utility model discloses a residential elevator, in particular to provide a residential elevator for satisfying the needs of residential buildings with simple structures. The elevator adopts a L-shaped litter holder and a side-open type single-casement horizontally sliding door. A litter compartment is arranged on one side of a shaft and a counterpoise, a counterpoise guide rail, and a litter compartment are sequentially arranged on the other side of the shaft. The size of the litter compartment and the shaft is accorded with specifications of the country. The utility model is applied to small-sized residential buildings, in particular to villa buildings.

Description

A kind of residential lift

Technical field

The utility model relates to a kind of elevator, and more particularly, it relates to a kind of small-sized elevator of residential building that adopts single fan horizontally sliding door.

Background technology

The residential building of supplying on China elevator market at present is the small-sized residential lift of villa building especially, and its pattern, structure and revenue passenger elevator are identical, and only sufficient element size is little by changing greatly.This elevator has all adopted the traction-type driving; Frame car frame carrying car; Guide rail is symmetrically arranged in about car; Counterweight is arranged on a car back or a side; Layer door divides horizontally sliding door or other open type two-fold horizontally sliding door in adopting with gate.This elevator structure pattern is layer, gate structural shape especially, is used for seeming on the small-sized residential lift that door opening width has only 0.7～0.8m having strengthened productive costs by many, the complex structure of number of components.

External popular small-sized hydraulic residential lift such as in Europe, this series products as Switzerland BERINGER elevator company, adopt the indirect jacking mode in side, crossbeam carrying car with L type sedan-chair frame, on the upright beam of L type sedan-chair frame, install and lead boots, the other open type two-fold of configuration horizontally sliding door, rational in infrastructure, it is little to take the hoistway area, has higher share of market.Because manufacturing, installation and the maintenance technique of hydraulic efficiency pressure system are had relatively high expectations, price is relatively costly, and this type of elevator is used less at home.

Summary of the invention

The purpose of this utility model is to simplify prior art constructions, provides a kind of and suits at the small-sized elevator of residential building especially villa building use.Its layer door and gate adopt single fan horizontally sliding door, and the member total number of this elevator car door system is reduced more than 50%, have reduced productive costs, have also reduced the failure in service rate.And under the less situation of door opening width, single door is more attractive in appearance than two-leafed door.

Single in general the simple and reliable for structure of horizontally sliding door of fanning, but its required " Zang Men amount " promptly door to open the back width dimensions that takies of door leaf bigger, if according to the hoistway arrangement of prior art, the width of hoistway will exceed the regulation of standard GB/T7025.1 " pattern of elevator principal parameter and car hoistway, machine room and size ".

For overcoming the deficiencies in the prior art, a kind of hoistway that both seldom accounted for is provided, the elevator that door system is simple in structure relatively again, the utility model is finished in the following manner: adopt L type sedan-chair frame, car is arranged in a side of elevator hoistways, and opposite side is arranged counterweight, counterweight guide rail, car guide rail successively.Gate and layer door adopt single fan horizontally sliding door, and the doorway is arranged on elevator hoistways by cage side.

Owing to adopted technique scheme, this residential lift that the utility model provides has such beneficial effect: made full use of the reasonably combined of elevator member and arranged, make and adopt the elevator of single fan horizontally sliding door not exceed two-leafed door elevator hoistways size in the national standard, the structure of elevator car door system obtains simplifying, and productive costs and operational failure rate reduce.

The specific embodiment

In Fig. a kind, elevator has adopted the traction-type driving, and traction ratio is 2: 1.Carry car 9 on the crossbeam of L type sedan-chair frame 7, be in the right side of elevator hoistways; On the upright beam of L type sedan-chair frame 7 car has been installed and has been led boots, matching with the car guide rail 13 that is installed in the hoistway right side to move lift car along guide rail up and down.The counterweight 4 of elevator and counterweight guide rail 6 are arranged on the left side of hoistway.Guiding to the machine room bearing beam on hoistway top behind the pulley 11 of traction steel-cable one end of towing machine through the car below fixes; Guiding to bearing beam behind the other end process counterweight pulley 3 fixes.During the elevator operation, towing machine is pressed the assigned direction running, leans on the friction force traction car of traction rope sheave and steel rope to move up or down.

Fig. 2 is the hoistway cross-section structure arrangement plan of present embodiment.This elevator is the 630kg residential lift.Press GB/T7025.1 " pattern of elevator principal parameter and car, hoistway, machine room and size " request of national standard, car size is 1100 * 1400mm, tunnel dimension 1800 * 2100mm, the midsplit type double door of recommending in the standard is changed into other open type single door, and the doorway has been located at the right side of hoistway.

Present embodiment adopts single-phase 220V ac power supply.In Fig. 3, frequency converter 15 be input as the alternating current 220V single phase poaer supply, be output as the three plase alternating current that voltage and frequency are adjusted by job requirement, join with hoisting motor 16.Executing changes coder 17 and 16 coaxial connections of electrical motor, and it is exported one the tunnel and connects frequency converter 15 as velocity feedback, and the position signal of PC 18 as car delivered on another road.PC 18 is cores of elevator control, and it connects the safety interlocking circuit 19 of elevator, receives interior choosing, the outgoing call signal of operating control 20, turns round by inverter control motor.

Fig. 4 is another embodiment of the present utility model, has been characterized in removing the machine room on elevator hoistways top, towing machine is moved into the upper left-hand of elevator hoistways from the bearing beam of machine room.About the 800mm of distance hoistway top, one frame-type bearing beam is set,, towing machine is installed on bearing beam by 2 car guide rails, 2 counterweight guide rail together support.Other structure of elevator is identical with embodiment 1.

This specification sheets is not described the irrelevant parts of the velocity limiter of elevator, safety tongs, control wheel etc. and technical characterictic of the present utility model.
