Abstract
The utility model relates to a gravity type automatic locking device of the protecting door of an elevating machine, and the device mainly comprises a gravity lock, a locking rod and a rotating shaft. The locking rod is fixed and connected to the protecting door, a clipping groove is arranged at the front end of the gravity lock, the clipping groove is matched with the locking rod, a circular hole is arranged at the rear end of the gravity lock, the rotating shaft is arranged in the circular hole, and the rotating shaft is connected with a cross bar which is connected with the door frame of the protecting door. The utility model has the advantages that the device adopts a simple gravity locking mode, thereby having the advantages of fastness and stabilization, uneasy inconstancy, reuse, convenient operation, and convenient disassembly and the assembly.
Description
Technical field
The utility model relates to the gig protective door blocking device of Industrial and Civil Engineering construction field, mainly is a kind of gig protective door gravity type boat davit automatic locking apparatus.
Background technology
In existing technology,, generally adopt Bolt door lock device or wind to collude the formula door lock assembly to the locking of gig inlet point protective door.In the work progress, the workmen all will close protective door after passing in and out protective door, in case material or personnel fall from the protection doorway, and the workmen is after opening protective door, owing to latch turned back to again or wind colludes to hang up and need do a series of action, for following the line of least resistance, often latch is not turned back to or keep watch to collude again and hang up, cause protective door often to be in the potential safety hazard of opening.And general Bolt door lock or wind to collude formula door lock assembly material thin, be subject to extraneous collision deformation and can not use poor durability.
Summary of the invention
The utility model will solve above-mentioned existing shortcoming, and gig protective door gravity type boat davit automatic locking apparatus a kind of simple in structure, easy to use is provided.
The utility model solves the technical scheme that its technical matters adopts: this gig protective door gravity type boat davit automatic locking apparatus, mainly comprise gravity lock, securing rod and turning cylinder, described securing rod is fixedly connected on the protective door, the front end of gravity lock has draw-in groove, draw-in groove matches with securing rod, and the rear end of gravity lock has circular hole, is provided with turning cylinder in the circular hole, turning cylinder and cross bar join, and cross bar is connected with the protective door doorframe.
The effect that the utility model is useful is: not yielding with the mode of simple gravity locking, firm stable, can reuse, and easy to use, dismounting is all very convenient.
Description of drawings
Fig. 1 is the utility model locking pre-structure scheme drawing;
Fig. 2 is a structural representation in the utility model locking;
Fig. 3 is the utility model locking back structural representation.
Reference numeral: gravity lock 1, circular hole 2, turning cylinder 3, cross bar 4, limited bolt 5, securing rod 6, draw-in groove 7, protective door 8.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1-Figure 3, this gig protective door gravity type boat davit automatic locking apparatus, mainly comprise gravity lock 1, securing rod 6 and turning cylinder 3, be fixedly connected with securing rod 6 on the protective door 8, gravity is locked 1 front end and is had draw-in groove 7, and when protective door locked, draw-in groove 7 matched with securing rod 6, gravity is locked 1 rear end and is had circular hole 2, be provided with turning cylinder 3 in the circular hole 2, turning cylinder 3 joins with cross bar 4, is connected to a fixed with attaching parts between cross bar 4 and the protective door doorframe, mounting or dismounting are convenient, engineering can be pulled down blocking device after finishing, and turnover is used, cross bar 4 is provided with limited bolt 5, makes gravity lock 1 to rotate in the certain angle scope.
When needs were shut protective door, as long as use the hand push protective door, securing rod 6 up lifted gravity lock 1 automatically, slipped in the draw-in groove 7 up to the guiding camber line of securing rod 6 by the gravity lock, and gravity lock 1 falls automatically, makes securing rod 6 be locked in the draw-in groove 7; When needs are opened protective door 8, lift gravity lock 1 with hand, make securing rod 6 break away from draw-in groove 7, pull out securing rod 6 and get final product.Limited bolt 5 on the cross bar 4 guarantees that gravity lock 1 is lifted Shi Buhui and too raises and overturn.
In multilayer or skyscraper main structure construction or decoration construction stage, material vertical transport general using gig carries out, all protective door need be set at each floor inlet point, gig protective door gravity type boat davit automatic locking apparatus is connected in the vertical rod of protective door doorframe with fastener, installs synchronously when the gig protective door is installed.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
