Description
Technical field
The utility model relates to building hoist technical field, is specifically related to a kind of preventing colliding with top building hoist.
Background technology
Along with the high speed development of national economy, the vehicle for constructions such as building hoist start to play huge effect at increasing building field, especially for large-engineering, and skyscraper place, the use of building hoist seems particularly important, and it can greatly boost productivity and save labour power.But in use, safety misadventure also happens occasionally elevator, so that people propose new requirement to secure context.A kind of safety prevention measure is only set; still safety requirements can not be ensured; therefore for preventing the generation of this type of safety misadventure; need to increase a kind of safety measure; when elevator runs to guide rail bracket top; Anti-over-hoisting device stops that elevator up runs, and prevents elevator from deviating from from guide rail bracket top, the safety of protection elevator and below personnel.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of preventing colliding with top building hoist.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of preventing colliding with top building hoist, comprises the guide rail bracket be made up of standard knot; The upper end of described guide rail bracket has preventing colliding with top section, and preventing colliding with top section upwards extends from the upper end of tooth bar, and when the gear of actuating device departs 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; On described guide rail bracket, and be positioned at described preventing colliding with top section upper position and be provided with bearing, described bearing is provided with spring; Described bearing dual-side is respectively welded with a channel-section steel, and described spring fitting is on channel-section steel.
Further technical scheme is that bearing is provided with mounting hole, and described bearing is fixedly connected with described guide rail bracket by bolt.
Further technical scheme is spring is rubber buffer spring.
Further technical scheme is also provided with preventing colliding with top travel switch between cage and guide rail bracket, and when this preventing colliding with top travel switch is in guard mode, gear still engages with tooth bar.
Compared with prior art; the beneficial effects of the utility model are: the utility model is in the process of building hoist work; if because the maloperation of staff or the fault of related electric parts cause cage not when stopping in the position set; gear is upwards walked with cage and is departed from tooth bar; the power now driving cage to rise disappears; within making cage remain on height of rushing to summit always; thus avoid cage to rush to summit the generation of accident; structure is simple; easy for installation; can prevent elevator from deviating from from guide rail bracket top, the safety of protection elevator and below personnel.
