Description
Technical Field
The invention relates to the field of elevators, in particular to a self-closing device of an elevator synchronous door motor.
Background
At present, elevator door machines are mainly divided into two types, one is a synchronous door machine, and the other is an asynchronous door machine. The synchronous door machine mainly features the use of a synchronous door knife, and is increasingly widely used in recent years. However, the problem of 'secondary door closing' of the synchronous door machine is common and is not well solved all the time; the synchronous door machine is easy to have the phenomenon of 'secondary door closing', because the synchronous door knife is in the process of locking the door of the holding layer door to the door lock of the releasing layer door when the door closing is about to finish, the output force of a door motor serving as a main power source of the door machine cannot be converted into the door closing force of the door machine, and the problem that the door machine stops closing before the door machine is not completely closed is easy to occur at the moment; is not an optimal solution, and for this reason, a self-closing device of an elevator synchronous door machine is provided.

Fig. 2 is a schematic structural diagram of a counterweight assembly of the self-closing device of the elevator synchronous door machine.
In the figure: 01. the gantry crane actively hangs the plate component; 02. the gantry crane passively hangs the plate assembly; 03. the gantry crane self-closing heavy hammer component; 101. a rope connecting bracket; 201. a sheave; 301. a linkage steel wire rope; 302. and (4) a heavy hammer.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the self-closing device for the synchronous door motor of the elevator comprises a door motor driving hanging plate assembly 01, a door motor driven hanging plate assembly 02 and a door motor self-closing heavy hammer assembly 03, wherein the door motor driving hanging plate assembly 01 corresponds to the door motor driven hanging plate assembly 02, one end of the self-closing heavy hammer assembly 03 is arranged above the driving hanging plate assembly 01 and the door motor driven hanging plate assembly 02, and the other end of the self-closing heavy hammer assembly is arranged on the right side of the door motor driven hanging plate assembly 02.
The gantry crane driving hanging plate assembly 01 is provided with a rope connecting support 101 for installing a self-closing heavy hammer rope.
And a rope wheel 201 is arranged on the gantry crane passive hanging plate component 02.
The gantry crane self-closing weight component 03 comprises a linkage steel wire rope 301 and a weight 302, one end of the linkage steel wire rope 301 is installed on a rope connecting support 101 on the gantry crane driving hanging plate component 01, the other end of the linkage steel wire rope 301 bypasses a rope wheel 201 on the gantry crane driven hanging plate component 02 to be connected with the weight 302, and the weight 302 keeps a vertical falling state.
The working principle is as follows: when the synchronous door machine opens the door, the driving hanging plate component 01 of the door machine and the driven hanging plate component 02 of the door machine run in opposite directions. The weight 302 is driven by the connecting rope bracket 101 through the linkage steel wire rope 301 to move upwards along a guide pipe fixed in the car door plate, and gravitational potential energy is stored. When the door is closed, the door machine driving hanging plate assembly 01 and the door machine driven hanging plate assembly 02 move in the opposite direction, the gravitational potential energy of the heavy hammer 302 is reduced, and the kinetic energy is increased; the door closing device can ensure that the door machine can be subjected to the door closing self-closing force provided by the heavy hammer 302 in the whole door closing process, and the door machine can complete the door closing action; thereby avoiding the problem of 'secondary door closing' easily occurring in the synchronous door machine.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
