Description
Technical field
The present invention relates to elevator technology field, specifically a kind of counterweightless home lift.
Background technology
Home lift is the elevator used for single family, and home environment space is limited, building shared by elevator hoistways
It is user's concern the most to build space and elevator safety.Therefore, it is proposed that counterweightless scheme, to reduce shared by counterweight
Space.Divide from type of drive, elevator without counterweight is forcibly driving elevator, and traditional pressure elevator is considered as
Safety coefficient is relatively low, compared with the traction-type driving elevator of routine, forced action type elevator wire rope negligible amounts, generally 2, and one
Denier rope loosing can cause hanging capacity to be greatly lowered, and the problems such as main frame unbalance stress and danger occur.Forced action type elevator
General up protection is realized by the protection device for over-speed ascending and limit switch of main frame, but electic protection switch is present
The potential safety hazard brought using failure.How safe reliability is improved.
The content of the invention
The technical problems to be solved by the invention be to provide a kind of reasonable in design, easy construction, occupy little space, safety can
The counterweightless home lift leaned on.
To achieve these goals, a kind of counterweightless home lift of the present invention, including lift car, lift car both sides
Guide rail, guide rail top are provided with horizontal spandrel girder, and spandrel girder side is provided with the first diversion sheave, and the second anti-rope is provided with the middle part of spandrel girder
Wheel, car upper beam are provided with the fag end device being connected with steel wire rope, and lower end is fixedly connected with the outside of the guide rail of the first diversion sheave
Drive main frame.
Above-mentioned counterweightless home lift, wherein, the fag end device includes the tapered sleeve being connected with the steel wire rope, fixed
The rope hitch plate of car upper beam is connected to, testing agency is additionally provided with below rope hitch plate.
Above-mentioned counterweightless home lift, wherein, the spandrel girder is provided with deceleration device.
Above-mentioned counterweightless home lift, wherein, the deceleration device is two.
Above-mentioned counterweightless home lift, wherein, the car upper beam hits plate provided with corresponding with the deceleration device.
The beneficial effect of invention is：Reasonable in design, easy construction, occupy little space, securely and reliably.
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail, but not as a limitation of the invention.

Embodiment
The structural principle and operation principle of the present invention are described in detail below in conjunction with the accompanying drawings：It is as shown in figure 1, of the invention
A kind of counterweightless home lift, including lift car 1, the guide rail 2 of the both sides of lift car 1, the top of guide rail 2 are provided with horizontal load-bearing
Beam 3, the side of spandrel girder 3 are provided with the first diversion sheave 4, and the middle part of spandrel girder 3 is provided with the second diversion sheave 5, and car upper beam 6 is provided with and steel wire
The fag end device 7 of rope connection, driving main frame 9 is fixedly connected with close to the outside lower end of guide rail 2 of the first diversion sheave 4.
Fag end device 7 includes the tapered sleeve 71 being connected with the steel wire rope 14, is fixedly connected on the rope hitch plate of car upper beam 6
72, the lower section of rope hitch plate 72 is additionally provided with testing agency 73.
Spandrel girder 3 is provided with deceleration device 10, preferably two, deceleration device 10, and car upper beam 6 is provided with and deceleration device 10
It is corresponding to hit plate 11.
Specific embodiment is as follows：
As shown in figure 1, the scheme of installation driving main frame 9 in top in traditional hoistway is changed to the outside of first floor guide rail 2 by the invention
Position is installed, and is realized first layer ground installation, is safeguarded driving main frame 9, solves traditional traction-type machine-roomless lift and fail for many years
Solve the problems, such as.
Because the first diversion sheave 4 is arranged on the upper end of guide rail 2, driving main frame 9 is fixedly connected with guide rail lower end again；So elevator
A downward pressure of guide rail 2 that gravity suffered by car 1 is applied to by the first diversion sheave 4 under it, and guide rail 2 is subject to
Under pressure act on again driving main frame 9 on, balance driving main frame 9 by the upward pulling force of steel wire rope 8.Therefore building
By the static pressure of elevator device base, and other belong to system internal force, without considering top layer guidance system, bottom layer driving master
The installation of the grade of machine 9 and structure stress problem, reduce Architectural Design Requirements.
The negligible amounts of forced action type elevator wire rope 8, generally 2, once steel wire rope 8, which releases, can cause hanging capacity significantly
Degree reduces and causes danger.Therefore testing agency 73 is provided with fag end device 7, once steel wire rope 8, which releases, loses pulling force, touched
Detection switch, stop elevator are concurrently out of order alarm.
If forcing driving class elevator major defect to be that limit switch fails, elevator drives main frame 9 when reaching the limit of position
Remain in operation and cause the accident of rushing to summit.Therefore deceleration device 10 has been installed additional on spandrel girder 6, when elevator is out of control, elevator crosses top
Layer level position, the plate 11 that hits of car upper beam 6 then start to oppress deceleration device 10, and the reaction force of deceleration device 10 will gradually be made
Stop lift car 1.Lift car 1 is system internal force to the impulsive force of deceleration device 10, and building will not be impacted.
Two deceleration devices 10 of equalization setting, can make car upper beam 6 when hitting deceleration device 10 on spandrel girder 3,
The impulsive force that spandrel girder 3 is subject to is more balanced, and the bending resistance of spandrel girder 3 is strengthened.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Know those skilled in the art when can be made according to the present invention it is various it is corresponding change and deformation, but these corresponding change and become
Shape should all belong to the protection domain of appended claims of the invention.
