Abstract
The utility model discloses a kind of machine-roomless lift, comprise hoistway, the car be arranged in hoistway, car guide rail, car diversion sheave, towing machine, counterweight and counterweight diversion sheave, be provided with lift car rope head attachment point and counterweight fag end attachment point in hoistway; Described car diversion sheave is arranged on cage bottom, and described counterweight diversion sheave is arranged on described counterweight top; Described counterweight fag end attachment point is fixedly connected with one end of steel rope, steel rope downwards through counterweight diversion sheave upwards, downward through towing machine again, then by with track adjusting wheel, the cooperatively interacting of car diversion sheave, the end of steel rope is made to be fixed on lift car rope head attachment point, described car is arranged on car guide rail, described car diversion sheave and described car guide rail arranged crosswise.Car diversion sheave and car guide rail arranged crosswise in the utility model, stressing conditions when making elevator cage operation is very reasonable, and has the stressed without any difference of machine room elevator car, and elevator runs can obtain good result of use.
Description
Technical field
The utility model relates to a kind of elevator, is specifically related to a kind of machine-roomless lift.
Background technology
Machine-roomless lift, relative to having for machine room elevator, that is, eliminates machine room, by places such as migration hoistway such as the control panel in former machine room, towing machine, velocity limiters, or replaces by other technology.The feature of machine-roomless lift does not have machine room exactly, and for builder reduces costs, machine-roomless lift generally adopts frequency conversion control technique and permanent magnet synchronous electric machine technology in addition, therefore energy-saving and environmental protection, does not take space except hoistway.In prior art, machine-roomless lift diversion sheave and car guide rail are arranged in parallel, and when elevator will be caused like this to run, guide rail can produce larger side force, and elevator traveling comfort can be able to reduce, and also can accelerate the wearing and tearing of guide piece simultaneously.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides solution.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of machine-roomless lift, comprises hoistway, the car be arranged in hoistway, car guide rail, car diversion sheave, towing machine, counterweight and counterweight diversion sheave, is provided with lift car rope head attachment point and counterweight fag end attachment point in hoistway; Described car diversion sheave is arranged on cage bottom, and described counterweight diversion sheave is arranged on described counterweight top; Described counterweight fag end attachment point is fixedly connected with one end of steel rope, steel rope downwards through counterweight diversion sheave upwards, downward through towing machine again, then by with track adjusting wheel, the cooperatively interacting of car diversion sheave, the end of steel rope is made to be fixed on lift car rope head attachment point, described car is arranged on car guide rail, described car diversion sheave and described car guide rail arranged crosswise.
Further technical scheme is that counterweight is arranged on described car rear by rearmounted arrangement.
Further technical scheme puts mounting means on towing machine passes through to be fixed on top layer in described hoistway.
Compared with prior art, the beneficial effects of the utility model are: car diversion sheave and car guide rail arranged crosswise in the utility model, make stressing conditions during elevator cage operation very reasonable, with have the stressed without any difference of machine room elevator car, elevator run can obtain good result of use.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment facade structures schematic diagram.
Fig. 2 is the utility model embodiment planar structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1 and Figure 2, the utility model embodiment machine-roomless lift, it comprises hoistway, the car 1 be arranged in hoistway, car guide rail 8, car diversion sheave 2, towing machine 3, counterweight 5, counter weight guide track 9 and counterweight diversion sheave 6, is provided with lift car rope head attachment point and counterweight fag end attachment point in hoistway; Specific embodiment is, car diversion sheave 2 is arranged on bottom car 1, and counterweight diversion sheave 6 is arranged on counterweight 5 top; Counterweight fag end attachment point is fixedly connected with one end of steel rope 7, steel rope 7 downwards through counterweight diversion sheave 6 upwards, downward through towing machine 3 again, then by with track adjusting wheel 4, the cooperatively interacting of car diversion sheave 2, the end of steel rope 7 is made to be fixed on lift car rope head attachment point, car 1 is arranged on car guide rail, as preferred embodiment, and car diversion sheave 2 and car guide rail 8 arranged crosswise in the present embodiment.Stressing conditions when making elevator cage operation is very reasonable, and has the stressed without any difference of machine room elevator car, and elevator runs can obtain good result of use.As preferred embodiment, adopt composite material to make to pouring weight, not cylinder iron counterweight block, decreases the use to iron and steel resource while reducing costs.The machine room series elevator of company's research and development also has energy regeneration function, makes the more energy-conservation and environmental protection of elevator.
Further, as preferred embodiment, counterweight is arranged on described car rear by rearmounted arrangement; And towing machine by put mounting means and be fixed on top layer in described hoistway.By counter weight guide track and car guide rail, the power of whole elevator is directly delivered to well pit; Towing machine promotes car or counterweight by the friction force of traction sheave and steel rope, side steel rope on traction sheave hangs counterweight by the diversion sheave on counterweight and the fag end in frame, the fag end that the opposite side steel rope of traction sheave is connected on car bottom diversion sheave and guide rail by the track adjusting wheel in frame hangs car, realize cage side steel rope by the rotation of traction sheave shorten or extend, thus realize rising or the decline of elevator.The present embodiment machine-roomless lift is arranged by rational space, thus reaches and can to realize installing machine-roomless lift in the tunnel dimension having machine room elevator.
Spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any one embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although the multiple explanatory embodiment here with reference to utility model is described the utility model, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the constituent elements of subject combination layout and/or layout.Except the modification of carrying out constituent elements and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
