Abstract
The utility model provides a protector for preventing a lift from falling down, composed of a self-locking protector 1 and a leveling protector 2. The utility model is characterized in that the self-locking protector 1 comprises a hanging cradle bottom board 3; a support frame 5 is arranged on the bottom board 3 through a support bar 4; a pulley gear 7 which can vertically slide is arranged in a connecting hole 6 on the support frame 5; a hook 8 is also hinged on the bottom board 3; one end of a connecting rod 9 is connected to the pulley gear 7, and the other end is connected to the middle part of a hook 9. When fortuitous events such as the sudden break of a steel cable, etc. appear, the hanging cradle can immediately lock independently, the hanging cradle can not fall down from a high altitude, and the security of a lift is improved; the utility model has the advantages of simple structure and easy fabrication.
Description
The utility model relates to a kind of elevator fender guard.
People generally adopt required equipment of elevator handling and material in the building operation of high-altitude; existing elevator does not generally possess fender guard; thereby in case wire cable rupture or winch brake failure etc. occur; elevator just might directly fall from the high-altitude; cause great threat for people's life security, bring loss to state and collective.
The purpose of this utility model is to provide a kind of can prevent the elevator falls fender guard.
The purpose of this utility model is to realize like this; it is made up of self-locking protecting device 1 and flat bed fender guard 2; it is characterized in that self-locking protecting device 1 comprises base plate 3; on base plate 3, be fixed with support 5 by cramp bar 4; the pulley gear 7 that can vertically slide is housed in the connecting bore 6 on support 5, also is hinged with hook 8 on base plate 3, an end of connecting rod 9 is connected on the pulley gear 7; the other end is connected in the middle part of hook 9, between carriage 7 and base plate 3 spring 10 is housed also.
Below in conjunction with accompanying drawing its structure is further described
Fig. 1 is the utility model self-locking protecting device structural representation
Fig. 2 is the utility model flat bed fender guard structural representation
The utility model is made up of self-locking protecting device 1 and flat bed fender guard 2; self-locking protecting device 1 comprises base plate 3; on base plate 3, be fixed with support 5 by cramp bar 4; the pulley gear 7 that can vertically slide is housed in the connecting bore 6 on support 5; on base plate 3, also be hinged with hook 8; one end of connecting rod 9 is connected on the pulley gear 7, and the other end is connected in the middle part of hook 9, between carriage 7 and base plate 3 spring 10 is housed also.
Hang hurdle flat bed fender guard 2 by steel rope 11, the steel plate wing 12, spring 13 is formed; steel rope 11 1 ends are connected in and hang on the hurdle door; the other end is connected on the steel plate wing 12 that is installed on the base plate 3, and the steel plate wing 12 is fixed by fulcrum, between the base plate 3 and the steel plate wing 12 spring 13 is housed.
Principle of work of the present utility model and using method are as follows, when winch rotates, when steel rope is stressed, drive the pulley gear upward movement, at this moment, because the effect of connecting rod 7, hook 6 inwardly rotates, and after pulley gear moves up, drives the whole hurdle upward movement that hangs again, the weight that hangs in the hurdle that is placed under the base plate 1 is hung to the high-altitude, when steel rope ruptured suddenly, the power that acts on the carriage suddenly disappeared, under the effect of spring force, pulley gear with respect to support 3 to lower slider, at this moment, connecting rod 7 is subjected to thrust, and hook 7 is outwards opened, hang on the hurdle frame on elevator next door, make elevator hang the hurdle and no longer fall.
After hanging the hurdle flat bed, open and hang the hurdle door, be connected in steel rope on the door and drive the steel plate wing and rotate it is horizontal, and be shelved on the cross bar of hurdle frame, make that to hang the hurdle stable.
The utility model has been owing to adopted said structure, when steel rope occurring and unforeseen circumstances such as rupture suddenly, hangs hurdle self-locking immediately, can not fall from the high-altitude, improved the safety of elevator greatly, and the utility model is simple in structure, and is easy to manufacture, practical.
