Abstract

The utility model discloses an automatic closing safety protection mechanism arranged on the inlet of the feeding platform of a building. The automatic closing safety protection mechanism is composed of a door-typed framework, a protection door arranged on the framework, and a padlock arranged on the beam of the framework, wherein, the tail part of the padlock extends a touching rod. The touching rod touches an outer lifter to automatically open the padlock, and then the protection door is closed by landing on ground. With simple structure and easy manufacture, loading and unloading, the utility model brings a reliable safety guard for on-site civilized constructions.

Description

Automatic safety protective mechanism for material delivering platform

At the construction site of China various places, the relatively normalized safety device of complete sum is not still adopted in its material loading platform entrance at present.The platform entrance generally is temporary protection fence or simple and easy protective door to be set and to send the special messenger to be responsible for the safety at this place.The nonstandard provisional protector of this long-term employing is waste of manpower and material resources on the one hand, still exist the hazards that personal injury occurs because of off one's guard on the other hand, it is very important therefore in the platform entrance a kind of security protection mechanism that closes performance automatically that standardizes and have being set.

The purpose of this utility model is that a kind of safety guard of closing automatically is provided in the material loading platform entrance.This device is by being arranged on portal frame on the scaffold and the automatic closing organ on the framework and forming along the up and down protective door of portal frame.Keep an eye on without the special messenger during use and can satisfy the security protection effect that the people is closed from door.

The utility model is realized by following scheme.A portal frame is set in the platform entrance.Make the protective door that both sides respectively have the collar with timber or metal material.The column slide rail of door frame is enclosed within the collar on a both sides.Padlock that is used to hang protective door of installing on the top rail of door frame.The afterbody of padlock stretches out a touching lever, and touching lever can realize that through the collision of outside elevator cage padlock opens automatically, and protective door lands the protection purpose of closing.Because the platform entrance is provided with the protection mechanism that such automaticity is closed, people have just no longer worried safety problem herein during construction.Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is automatic closed safe protection mechanism organigram.

Fig. 2 is the damping counterweight schematic diagram in the protection mechanism column slide rail.

Fig. 3 is the structure of padlock cut-away view of protection mechanism

With reference to accompanying drawing, protective door (2) that the utility model rises and falls by column slide rail type door frame (1) with along slide rail (5) and the padlock that is arranged on framework (1) crossbeam (4) are formed.Column slide rail (5) is made of metal tube.Suspending damper (15) and counterweight (16) (see figure 2) in midair through slide rail (5) top by flexible wirerope in the cavity of slide rail (5).The other end of wirerope is connecting protective door, reduce when landing with side door its land speed and the door vibrations.Protective door (2) both sides upper-lower position respectively is provided with a collar (3), and the collar (3) is enclosed within on the slide rail (5), by artificial election protective door (2) is suspended on the padlock on the doorframe crossbeam (4).Padlock is made up of lock housing (7) and two rollers (11) and the lever touching lever parts such as (13) that are arranged on lock pin (8) in the lock housing (7), compression spring (9), slide fastener (10), baffle plate (12), baffle plate back.The lock housing front end is equipped with a fastener (6), plays the guiding closing function of protective door (12).The lock pin rear end connects slide fastener (12).Compression spring (9) is being overlapped in the slide fastener outside.The baffle plate (12) in lock pin rear end and the lock housing is supported at its two ends of described compression spring respectively.The other end of slide fastener is pulled out from the middle part perforate of described baffle plate, passes between two rollers (11) and is connected with a termination of touching lever.Touching lever is hinged on the medium position of lock housing rear end by an axostylus axostyle (14) for fulcrum, and the other end then stretches to the dispatch from foreign news agency ladder.In order not influence the lever operation angle of touching lever, the latter half of special one-tenth fishtail structure (see figure 3) of lock housing, personnel's elevator cage of leaving away is up or falls and all can stir touching lever by the cross bar of elevator cage like this, touching lever drops slide fastener and causes lock pin indentation lock housing, thereby the protective door that is suspended on the lock pin is landed automatically, reach the purpose of closing the material loading platform entrance.

The utility model simple structure, practical, load and unload also easily, can not only effectively promote the construction that civilises of job site, bring reliable safety guarantee but also can be the constructor.
