Description
Technical field
The present invention relates to a kind of elevator, particularly a kind of elevator of machine room.
Background technology
in prior art, a kind of machine-roomless lift is arranged, its structure mainly includes car, towing machine, counterweight frame and steel rope, described steel rope two ends are respectively equipped with rope hitch plate, rope hitch plate elasticity is connected on the crossbeam at elevator top, towing machine and control housing are arranged on the concrete wall surface of hoistway top or hoistway bottom, towing machine is provided with traction sheave, counterweight frame is provided with track adjusting wheel, described car bottom bilateral symmetry is provided with the first diversion sheave and the second diversion sheave, described steel rope is walked around track adjusting wheel successively, traction sheave, the first diversion sheave and the second diversion sheave, counterweight frame and car are suspended in elevator, control housing is arranged on the side of car, thereby this device need not to arrange machine room.Its weak point is: it installs inconvenient, needs to carry out towing machine at top of building and installs, and need to the towing machine that weight is larger during installation lifts the top to elevator, time-consuming, effort; Cost is higher, and communication is connected to connect by traveling flat cable to existing car with control housing, and the construction of cable is huge, and erected cost is high; Existing towing machine installation is had relatively high expectations to hoistway, needs simultaneously to do a large amount of burying work beforehands, and towing machine is arranged on hoistway top layer or bottom, needs to strengthen height or the degree of depth of top layer or bottom, and the laid down cost of elevator is higher; In addition, existing overhauling elevator difficulty, and be not easy to save oneself.
Summary of the invention
For above-mentioned technical matters, the present invention proposes a kind of technical scheme of machine-roomless lift, make the elevator construction cost low, control convenient.
technical scheme of the present invention is as follows: a kind of machine-roomless lift, comprise car, towing machine, counterweight frame and flexible traction part, described car and counterweight frame are suspended in hoistway, towing machine is provided with the traction sheave that is connected with driver train, counterweight frame is provided with track adjusting wheel, described car bottom is provided with diversion sheave at the bottom of at least one sedan-chair, described towing machine is fixedly mounted on bottom car, well headroom also is provided with the top diversion sheave, flexible traction part one end is connected to well headroom, the other end is upwards walked around the top diversion sheave after walking around track adjusting wheel again, then walk around traction sheave along car one side downwards, walk around again at the bottom of sedan-chair and upwards be connected to well headroom along the car opposite side after diversion sheave, the cornerite of described flexible traction part on traction sheave is greater than 90 °.
Compared with prior art, beneficial effect of the present invention is: one, elevator is easy for installation, can carry out towing machine at architecture bottom layer and install, and has reduced towing machine is lifted shortcoming to top layer, installs safer.Its two, need not strengthen height or the degree of depth of hoistway top layer or bottom, saved laid down cost.Its three, because towing machine need not to be fixed in hoistway, the built-in fitting in hoistway is few, the hoistway construction is more convenient.
For guaranteeing to have enough large friction force between flexible traction part and traction sheave, avoid skidding, at the bottom of sedan-chair, diversion sheave can be provided with two, and flexible traction part is walked around after traction sheave at the bottom of the sedan-chair diversion sheave top and walked around, more upwards is connected to well headroom after the diversion sheave bottom is walked around at the bottom of another sedan-chair again.This structure makes the cornerite of flexible traction part on traction sheave larger, can bear larger friction force; The size of traction sheave also can be done littlely.
For ease of control housing is overhauled, described control housing for controlling the elevator operation is arranged on car one side.During maintenance, car can be placed in bottom hoistway, when control housing is overhauled, need not to ascend a height, in daily management, also can overhaul control housing by passage in car.Communication is connected to connect by ribbon cable to the car of traditional elevator with control housing, and in the present invention, the lift car communication cable is connected with control housing nearby, has saved a large amount of control paths.
Described flexible traction part can be steel rope, can also be the polyurethane composite steel band.When especially adopting the polyester composite steel band, due to large with the traction sheave contact surface, have larger friction coefficient between the two, can do traction sheave very little, alleviated weight, saved material.
For can reduce elevator operation and stop between the impact that causing, described flexible traction part elasticity is connected to well headroom.
Save oneself for convenience of the personnel in car, described car is provided with the spanner that declutches of manual control towing machine.In prior art, also be provided with the palm that declutches on towing machine, therefore run into emergency situation, as when cutting off the power supply, can utilize the weight difference of car and counterweight that elevator is parked in flat bed nearby, but because towing machine and car are separated, can only just can operate by other people operation the operation of can't saving oneself of the personnel in elevator.The improvement of the technical program makes the personnel in elevator oneself to operate, and elevator is parked in flat bed nearby, and elevator uses safer.
