Abstract
The utility model relates to the field of a construction lift, particularly to a roof-impacting prevention construction lift. The roof-impacting prevention construction lift comprises a tower frame and a suspension cage which is assembled on the tower frame through a guide roller, wherein the top of the suspension cage is provided with a driving device; the driving device is meshed with a rack which is arranged on the tower frame through a gear; the upper end of the tower frame is provided with a roof-impacting prevention section extending upwards from the upper end of the rack; when the gear of the driving device breaks away from the rack from the upper end of the rack, the distance between the top of the lifting cage and the upper end of the roof-impacting prevention section is larger than the roof-impacting height of the lifting cage; the gear runs upwards along with the lifting cage and breaks away from the rack in the working process of the construction lift if the lifting cage is not stopped in the set position and the force for driving the lifting cage to lift disappears to ensure that the lifting cage keeps within the roof-impacting height, so that the roof-impacting accident of the lifting cage is avoided. According to the roof-impacting prevention construction lift, the roof-impacting problem of the lifting cage of the traditional construction lift is solved.
Description
Technical field
The utility model relates to building hoist field, especially a kind of preventing colliding with top building hoist.
Background technology
The building hoist construction elevator that usually is otherwise known as.The kind of building hoist is a lot, counterweightless is arranged and two kinds of counterweights are arranged by its operation scheme, is divided into manual control formula and automatic control type by its mode.It can also add converter plant and PLC control module on demand, can also add floor call device and leveling device in addition.The building hoist major part of using in the market is as the counterweightless formula, drive system is placed in above cage, can reduce noise in cage on the one hand, makes headroom increase in cage, also make simultaneously transmission more steadily, mechanism vibrations is less, installation process has also been simplified in the counterweightless design; Intelligent for the ease of the control of construction elevator and its, construction elevator can also be installed frequency converter, and not only energy-conservation but also can infinite speed variation, operation be got up more steady, takes also more comfortable; It is more convenient that the construction elevator of installation leveling device is controlled, and rests in more accurately the floor that needs stop; The floor call device is installed is made the information flow when using more convenient, make management more convenient.
At secure context; present construction elevator is guaranteed; at first guarantee for electrical safety; construction elevator is equipped with the travel switches such as sliding door travel switch, clamshell doors travel switch, roof door travel switch, upper limit travel switch, lower limit travel switch; as long as there is any one travel switch to be in guard mode, electrical motor will be in braking state.yet the cage of the overwhelming majority in present building hoist is assemblied on pylon by guide roller, during work, rolling on pylon moves up and down cage by guide roller, wherein the propulsive effort that moves up and down of cage comes from actuating device, as above-described, actuating device is located at the cage top of cage, generally, actuating device is provided with gear, pylon is provided with the tooth bar of answering with described gear mesh, in present building hoist, tooth bar is all to extend to from bottom to top the top of pylon always, the lifting of the intermeshing drive cage between wheel and rack, according to relevant criterion, cage has certain height of rushing to summit, this is rushed to summit is highly that upper limit travel switch by above-mentioned limits, yet in actual production process, uncertainty due to electrical control, as factors such as electrical damage, the phenomenon that cage is rushed to summit still exists, this kind situation is in case occur, staff's life security will directly be threatened, cause the loss that to retrieve, in addition, in present building hoist, because needs prevent that cage is overweight, cage all hangs on actuating device by the sensor bearing pin, and the sensor bearing pin is hollow structure, so intensity is limited, due to the shearing that is subject to for a long time cage, therefore the off-axis phenomenon appears in unavoidable meeting, and then draws the potential safety hazard that causes cage to fall, and this obviously also greatly reduces the safety factor of building hoist.
In sum, still there is the potential safety hazard that cage is rushed to summit and cage falls in present building hoist.
Summary of the invention
The purpose of this utility model is to provide a kind of preventing colliding with top building hoist, the problem of rushing to summit with the cage that solves existing building hoist.
In order to address the above problem, preventing colliding with top building hoist of the present utility model is by the following technical solutions: the preventing colliding with top building hoist, comprise pylon and be assemblied in cage on pylon by guide roller, the cage of cage pushes up has actuating device, the tooth bar engagement of actuating device by arranging on gear and pylon, the upper end of pylon has the preventing colliding with top section, the preventing colliding with top section extends upward from the upper end of tooth bar, when the gear of actuating device broke away from from tooth bar upper end and tooth bar, the cage top was not less than rushing to summit highly of cage with the distance of preventing colliding with top section upper end.
Also be provided with the preventing colliding with top travel switch between cage and pylon, when this preventing colliding with top travel switch was in guard mode, gear still meshed with tooth bar.
Described cage hangs on actuating device by the sensor bearing pin, also is provided with horizontal safety plug between actuating device and cage, and this safety plug was not subjected to the shearing of actuating device and cage before the sensor bearing pin damages.
Have the gap on the outer peripheral face of described safety plug and cage or between the hole wall of the respective pin hole that arranges on actuating device, this gap makes safety plug not be subjected to the shearing of actuating device and cage before the sensor bearing pin damages.
because the pylon upper end of preventing colliding with top building hoist of the present utility model has the preventing colliding with top section, the preventing colliding with top section extends upward from the upper end of tooth bar, when the gear of actuating device breaks away from from tooth bar upper end and tooth bar, the distance of cage top and preventing colliding with top section upper end is not less than the height of rushing to summit of cage, therefore, in the process of building hoist work, if when causing cage not stop in the position of setting due to the fault of staff's maloperation or related electric parts, gear is upwards walked and breaks away from tooth bar with cage, drive the power disappearance that cage rises this moment, make cage remain on to rush to summit in height always, thereby avoid the rush to summit generation of accident of cage, because rack-and-gear is pure physical construction, therefore can guarantee absolute reliability, this shows, the problem that the cage that preventing colliding with top building hoist of the present utility model has solved existing building hoist is rushed to summit.
Further, described preventing colliding with top travel switch can be used as one barrier before the preventing colliding with top section, avoids in most cases the disengaging of wheel and rack, guarantees normal, the continuous working of building hoist; Described safety plug can replace sensor axis to guarantee articulating of cage and actuating device when the sensor pin axle fracture automatically, thereby prevents that the accident that cage falls from occuring; The gap, as the term suggests refer to very little interval, adopting safety plug to come the assurance pin not to be subjected to the shearing of actuating device and cage can make safety plug take over corresponding sensor bearing pin in the moment of sensor pin axle fracture before the damage of sensor bearing pin with the gap between corresponding pin-and-hole works, reduce the impact of cage to safety plug after the sensor pin axle fracture, further optimize the safety performance of cage.
