Abstract

The utility model relates to a lift truck outside a window for a building, which is composed of a rolling and crossing truck, a steel cable, a motor, a speed uniforming device. One end of the steel cable is led outside a window to pull the rolling and crossing truck, and the other end is wound on a rope winding wheel; the power of the motor is output to a worm and gear mechanism, a shaft of a worm gear is provided with a clutch gear engaged with the rope winding wheel, and the rope winding wheel is also engaged with a sprigging gear; a shaft of the sprigging gear is connected with a speed uniforming device playing the function of the reduction of the falling speed. The motor can be utilized to pull the rolling and the crossing truck to lift heavy objects as well as the slow speed and the safety at the time of the falling can be ensured by the speed limiting function of the speed uniforming device.

Description

Building is lift truck outside window

The utility model relates to a kind of lifesaving appliance, and particularly a kind of building is lift truck outside window.

At present, along with increasing rapidly of skyscraper, because of reasons such as high building catch fire, captive can only happen occasionally from the emergency that window shifts earthward.If only by with one of hand grip by window hang down to the rope on ground earthward landing shift, for most people, because of muscle power and factor such as terrified are difficult to realize safe transfer.The high building life saving device structure of arising at the historic moment is various, the decline but majority can only slow down, and can not rise.Relevant by retrieval document still finds no and the same or analogous record of the utility model.

The purpose of the disconnected type of this practicality just provides a kind of easy and simple to handle, safe and reliable, and the building of energy lifting is lift truck outside window.

Technical solution of the present utility model is: outside the end extraction window of steel wire rope, be used for drawing and roll car more, the other end is wrapped on the bull wheel; The power of motor passes to worm-and-wheel gear after output, be coaxially arranged with clutch gear with worm gear, and this gear is meshed with bull wheel, and bull wheel also is meshed with spragging gear simultaneously, and the axle of spragging gear links to each other with the at the uniform velocity device that works the falling speed that slows down.

The utility model is reasonable in design, compact conformation, and long service life, easy and simple to handle, good reliability can be realized the purpose of safely dropping.

Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.

Fig. 1 is an overall structural arrangement schematic diagram of the present utility model;

Fig. 2 is that A-A among Fig. 1 is to the structure cutaway view;

Fig. 3 is that B-B among Fig. 1 is to the structure cutaway view.

With reference to accompanying drawing, form more by car 1, steel wire rope 2 and motor 3 etc. by rolling for the utility model, one end of steel wire rope 2 is wrapped on the bull wheel 7, other end extraction window is outer, and car 1 links to each other with rolling more, pass to worm-and-wheel gear 4 after the output of the power of motor 3, worm-wheel shaft 5 is provided with clutch gear 6, and the clutch key 13 that employing can be slided vertically between clutch gear 6 and the worm-wheel shaft 5 is connected, moving by 14 controls of control rope of clutch key 13 is provided with spring 15 in a side of clutch key 13; Clutch gear 6 is meshed with bull wheel 7, bull wheel 7 also is meshed with spragging gear 8 simultaneously, the axle of spragging gear 8 is fixed with flywheel piece 11 with fly frame 10 lockings in key and the device at the uniform velocity 9 on fly frame 10, be welded with brake ribbon 12 on the superficies of flywheel piece 11.

During rising, utilize the power traction of motor to roll car rising more, reach the purpose that promotes weight, this moment, at the uniform velocity the interior flywheel rotation of device was slow, does not reach centrifugal action owing to there is worm-and-wheel gear to slow down, and did not produce the speed limit effect to rising.

During decline, pulling is controlled rope clutch key is pulled out also location of clutch gear, and this moment, bull wheel was subjected to gravity effect rotation, drive clutch gear and dally around worm-wheel shaft, and the drive spragging gear rotates; Driven by spragging gear, flywheel piece 11 rapidly rotation produces centrifugal actions, and brake ribbon 12 and device housing 16 at the uniform velocity produce the friction decrease speed that slows down, make when at the uniform velocity device guarantees to descend at the uniform velocity, slowly.Because worm and gear has unidirectional drive characteristic, played self-locking action, do not spur the control rope during decline before, roll and vehicle-mountedly more also do not fall after heavy, can guarantee the handling safety that once escapes when in danger.
