Abstract

The utility model provides a haulage rope wheeled machine-room-less elevator, which comprises an elevator car, lifting in a hoistway; a counterpoise, elevating along the opposite direction of the elevator car; a guide rail used by an elevator car, restricting the up-and-down and vertical elevating of the elevator car; a guide rail used by the counterpoise, restricting the up-and-down and vertical elevating of the counterpoise; a rope, suspending the elevator car and the counterpoise; a tractor, a traction sheave and an elevator car sheave; wherein, the tractor is a permanent magnetic gearless tractor, the traction sheave and the elevator car sheave are linearly arranged on a horizontal projection plane, the tractor is fixed on the top end of the guide or positioned on the top of the hoistway to be fixedly connected with the hoistway wall via a bearing beam and a frame. The haulage rope wheeled machine-room-less elevator has the advantages of unique design and novel structure, which greatly improves the economy of the elevator, remarkably improves safe reliability and successfully minimizes the height of the top level of the hoistway, thus having a bright application prospect.

Description

The traction rope wheel type machine-roomless lift
Technical field
The utility model relates to a kind of machine-roomless lift, relates in particular to a kind of traction rope wheel type machine-roomless lift.
Background technology
Elevator is as manned cargo-carrying instrument, and existing quite long history has become the modern architecture inalienable part.In order to satisfy the constantly demand of the construction market of development, elevator technology also is being showing improvement or progress day by day.From the development of the early 1990s in last century so far, the machine-roomless lift technology is ripe relatively.Machine-roomless lift is compact conformation, saving space not only, and efficient energy-saving, owing to reduced the essentiality that machine room exists, is particularly useful for the restricted building of top layer.In fact, for the restricted building of top layer, need meet the demands as machine-roomless lift.Simultaneously, the designing technique of machine-roomless lift also provides more wide space for the architect carries out later-model Building Design.The traction-type machine-roomless lift is more and more approved by market Just because of this.
Prior art, machine-roomless lift adopt slim towing machine usually, are arranged in well headroom; In order to save hoistway space, counterweight is arranged in the left side or the right side of car, because counterweight is a thin-and-long, utilize herein the long and narrow space of car and the borehole wall to arrange slim towing machine for this reason, but slim towing machine is except the shortcoming of itself structure, its height of contour has restricted machine-roomless lift can't be reduced the hoistway headroom height, and in order to utilize the counterbalancing car weight, can increase the counterweight sectional area; Enlarge tunnel dimension, perhaps counterweight is designed to abnormally-structured, thereby increased manufacture difficulty greatly.
In addition, adopt slim towing machine, its width dimensions is bigger, traction sheave needs vertical car gate direction to arrange, as Fig. 1~2, no matter how car sheave to arrange, the traction sheave wire rope transfers need be changeed certain angle during to car sheave, the torsion oscillations of steel rope just is directly passed to car, the safe reliability shortcoming.
Summary of the invention
The purpose of this utility model provides a kind of traction rope wheel type machine-roomless lift, is intended to effectively improve the economy and the safe reliability of elevator, the hoistway headroom height can be reduced to minimum.
The purpose of this utility model is achieved through the following technical solutions:
The traction rope wheel type machine-roomless lift comprises: car, and it is lifting in hoistway; Counterweight, it is along the direction lifting opposite with car; The car guide rail, its restriction car is vertical lift up and down; To reusing guide rail, its restriction counterweight is vertical lift up and down; Rope, its suspension craning cab and counterweight; And towing machine, traction sheave and car sheave, it is characterized in that: described towing machine is the permanent magnetism gearless machine, described traction sheave and car sheave are linearly arranged on horizontal plane.
Further, above-mentioned traction rope wheel type machine-roomless lift, described towing machine are fixed on guide rail topmost.
Further, above-mentioned traction rope wheel type machine-roomless lift, described towing machine are positioned at well headroom and are connected and fixed by bearing beam or support and well enclosure or top board.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
The utility model traction rope wheel type machine-roomless lift adopts the permanent magnetism gearless machine, and traction sheave and car sheave are linearly arranged on horizontal plane, effectively avoid steel rope generation torsion oscillations between traction sheave and car sheave.Compared with prior art, unique, the novel structure of the utility model design, improved the economy of elevator greatly, significantly improved safe reliability, success realizes reducing to the hoistway headroom height minimum, the travelling comfort of this lift appliance is good, and economic benefit and social effect are remarkable, has fabulous application prospect.
