Abstract
A safety door locking device of a lifter suspension cage comprises a safety hook and a locking block, wherein the safety hook is fixedly installed on a lifter suspension cage machine frame through a pin shaft in a rotating mode and the locking block is fixed in a lifter suspension cage door and matched with the safety hook. A compression spring is arranged at the tail portion of the safety hook. At least one locking groove is formed in the locking block, wherein the locking groove is matched with the safety hook. The safety door locking device of the lifter suspension cage is reasonable in structure and greatly improves safety of the lifter suspension cage.
Description
Technical field
The utility model relates to the elevator technology field, is specifically related to the safety door lock device that uses on a kind of elevator craning cage.
Background technology
At present, in building or other industry industry, the elevator machine is a kind of requisite equipment, and it is mainly used in transporting workmen and construction material in construction, because the hoisting depth of elevator is sometimes higher, therefore require the needs of cage to possess very high safety.Stipulate in JGJ59-99 construction safety check criteria according to Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD): the material elevators such as well cabinet frame, portal frame not only will be installed anti-falling safe protection device; and safety pretection device for stop must be installed; this mainly is to consider that overload might may appear in equipment in the lifting process or other reason makes that hoist rope is broken, cage falls, and causes fatal crass's grave accident.
And simultaneously, the door lock assembly of cage also is one of them key point.At present, the construction elevator cage simple gate of using on the market, a kind of do not have a safety device, and cage is can arbitrarily opening in the middle of the operational process up and down, so exist great potential safety hazard; Another kind is the walk away safety hook, hooks following square steel tube by the deadweight of hook with safety tong, and this kind hook with safety tong is in service at cage, because cage vibration and other factors, hook with safety tong may be opened voluntarily, so also exist certain potential safety hazard.Therefore need a kind of rational in infrastructure, door lock assembly that safety performance is high of design.
The utility model content
The technical matters that the utility model solves is to provide a kind of safety door lock device of elevator craning cage, thereby solves the problem in the above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of safety door lock device of elevator craning cage, comprise that utilizing bearing pin to rotate is installed on the hook with safety tong on the described elevator craning cage frame and is fixedly installed on the described elevator craning cage door and the latch that cooperates with described hook with safety tong, it is characterized in that, the afterbody of described hook with safety tong is provided with Compress Spring, and is provided with the lock groove of at least one and described hook with safety tong coupling on the described latch.
In the utility model, when not opening the door, under the effect of Compress Spring, one end of hook with safety tong inserts in the lock groove of described latch, and opposite house carries out locking, and because the existence of Compress Spring, hook with safety tong can not flick, and has greatly improved the safety of elevator craning cage.
As a kind of improvement, be provided with the gear block for spacing described hook with safety tong afterbody on the described elevator craning cage frame.
As a kind of improvement, be provided with two lock grooves on the described latch.
Owing to adopted above structure, the utlity model has following beneficial effect:
The safety door lock device of the elevator craning cage that the utility model provides, rational in infrastructure, when cage does not open the door, under the effect of Compress Spring, one end of hook with safety tong inserts in the lock groove of described latch, and opposite house carries out locking, and because the existence of Compress Spring, hook with safety tong can not flick, and has greatly improved the safety of elevator craning cage.
