Abstract

The invention provides an observation elevator without a machine room. The observation elevator without the machine room comprises a shaft, an elevator car, an elevator frame arranged outside the elevator car, an elevator bottom rope sheave beam, a guide rail, load-bearing beams, a traction machine, a counterweight, a counterweight diversion sheave and a counterweight side rope end device, wherein the elevator bottom rope sheave beam is arranged at the bottom of the elevator car, two diversion sheaves are further arranged on the elevator bottom rope sheave beam, and installed on the elevator bottom rope sheave beam through a diversion sheave shaft perpendicular to the elevator bottom rope sheave beam, and the elevator bottom rope sheave beam is arranged at the bottom of the elevator car in a mode that an acute angle is formed between the center line of the elevator bottom rope sheave beam and the center line of the guide rail fixedly arranged in the shaft; the traction machine and the counterweight side rope end device are fixed to the load-bearing beams on the upper portion of the elevator frame, a declination angle is kept between the projection shadow, on the horizontal plane, of the center line of a traction machine wheel of the traction machine and the projection shadow, on the same horizontal plane, of the center line of the elevator bottom rope sheave beam, and the counterweight and the counterweight diversion sheave are arranged on the left or right side of the elevator car. The observation elevator without the machine room has the advantages that the size of the shaft of the elevator without the machine room is reduced, the structure is more compact, the utilization ratio of the shaft is increased, and the civil engineering cost is saved.

Description

A kind of machine room Sightseeing Lift

Technical field

The invention belongs to elevator technology field, especially relate to a kind of machine room Sightseeing Lift.

Background technology

At present, machine room elevator and machine-roomless lift is had to be two kinds of common forms of elevator, there is machine room elevator structural safety, but it is large to take up room, machine-roomless lift can conserve space, the parent being more and more subject to everybody looks at, but known machine room sedan-chair frame arrangement is straight beam to be arranged, due in order to make safety tongs line near car center of gravity as far as possible, so diversion sheave is generally in position to the rear in the middle of car, cause counterweight position to the rear, machine-roomless lift shaft depth is increased, add use cost, owing to being subject to the restriction of building structure and cost, the shaft depth how reducing machine room Sightseeing Lift is problem demanding prompt solution.

Summary of the invention

The problem to be solved in the present invention needs larger shaft depth rearward to overcome existing machine room Sightseeing Lift counterweight position, provides a kind of machine room Sightseeing Lift, and the relative car reach in towing machine position, makes counterweight not exceed car depth, reduce shaft depth.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of machine room Sightseeing Lift, comprises rope sheave beam, guide rail, bearing beam, towing machine, counterweight, counterweight diversion sheave, counterweight-side fag end device at the bottom of hoistway, car, the sedan-chair frame be arranged on outside car, sedan-chair, at the bottom of described sedan-chair, rope sheave beam is arranged in cage bottom, rope sheave beam at the bottom of sedan-chair is also provided with two diversion sheaves, it is by being arranged on rope sheave beam at the bottom of sedan-chair perpendicular to the diversion sheave axle of rope sheave beam at the bottom of described sedan-chair, and the line of centers of rope sheave beam at the bottom of sedan-chair is arranged in cage bottom with acutangulating with the line of centers of the guide rail be fixed in hoistway, described towing machine and counterweight-side fag end device be fixed on be positioned at sedan-chair frame top described bearing beam on, the projection of line of centers in described same level of rope sheave beam at the bottom of the line of centers of the traction wheel of described towing machine and described sedan-chair keeps a drift angle, described counterweight and counterweight diversion sheave are arranged on left side or the right side of car.

Further, at the bottom of described sedan-chair, the angle angle of the line of centers of rope sheave beam and the line of centers of guide rail is 12-38 degree.

Further, to take turns limit to horizontal throw and counterweight diversion sheave that counterweight diversion sheave takes turns limit identical to the horizontal throw of the counterweight fag end of counterweight-side fag end device on the traction wheel wheel limit of described towing machine.

The advantage that the present invention has and good effect are: owing to adopting technique scheme, at the bottom of sedan-chair, rope sheave beam and guide rail are arranged with being wired to acute angle, at the bottom of sedan-chair, the traction wheel of rope sheave beam and towing machine keeps a drift angle on car level face, return rope sheave to be directly connected with counterweight diversion sheave by the traction sheave of towing machine, make towing machine position in advance, the relative car position in counterweight position in advance, the fitting depth of counterweight is made not exceed car depth, make elevator structure without machine room compacter, increase the degree of utilization of machine-roomless lift hoistway, reduce machine-roomless lift tunnel dimension, save civil engineering cost.
