Description
Technical field
The present invention relates to elevator counterweight fields, disconnect early warning fall arrest electricity more specifically to a kind of hoist ropes
Terraced counterweight.
Background technique
Counterweight is a component part of elevator traction system, and its role is to reduce the power of hoisting motor and traction
Torque on wheel, worm gear.
Counterweight is located in hoistway, is connect through traction sheave with carriage by hoist ropes.In running process of elevator, counterweight
Device is slided on counter weight guide track by counterweight guide shoe, plays balanced action.Counterweight is by counterweight frame and to pouring weight two parts group
At.Since counterweight iron is put into counterweight frame, counterweight iron is answered easy to carry.The configuration quantity of counterweight iron should make counterweight iron and counterweight frame
Gross weight be equal to carriage gross weight add (0.4-0.5) nominal load capacity.Counterweight frame channel steel or with 3-5mm steel plate crimping at channel steel shape
It is welded afterwards with steel plate.Due to use occasion difference, the structure type of counterweight frame is also slightly different.According to different traction sides
Formula, counterweight frame, which can be divided into, has wheel counterweight frame and for 1:1 hoist cable method without two kinds of counterweight frame of wheel for 2:1 hoist cable method.According to
Different counter weight guide track, and being divided into for T-rail, using the counterweight frame of spring slide guide shoe, and for hollow guide rail,
Using two kinds of counterweight frame of rigidity sliding guide shoe.When the nominal load capacity difference of elevator, fashioned iron used in counterweight frame and steel plate
Specification is also different.When making counterweight frame straight beam with the fashioned iron of different size, it is necessary to corresponding with fashioned iron notch size to pouring weight.
Even if elevator the relevant technologies in the prior art have been relatively mature, but elevator accident still emerges one after another.It is many
It is well known, it is bigger to pouring weight quality in counterweight frame to guarantee that elevator safety needs, for counterweight frame upper end hoist ropes it is strong
Degree requirement is higher, even if the strength character of hoist ropes is good again, after long-time use, performance must be reduced, although dimension
Guarantor person can carry out periodic detection replacement to hoist ropes, but can inevitably have a hoist ropes and not be timely detected and replace, especially
It is the slightly worse hoist ropes of a little quality, once hoist ropes disconnects, then the counterweight frame connected below can fall, and causes considerable safety
The great elevator safety accident of the disconnection of the hoist ropes on an elevator counterweight just has occurred in accident, such as 2018 cities Nian Mou,
Although having the honor no casualties, this plays elevator event and brings huge fear to the broad masses for taking elevator.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a kind of hoist ropes to disconnect early warning fall arrest
Elevator counterweight, it is additionally arranged auxiliary hoist ropes group on the basis of the main horseline group of conventional lift counterweight, in original
After some main horseline groups surprisingly disconnect, continues to provide traction effect using auxiliary hoist ropes group, be simultaneously emitted by early warning, and
When warn occupant's elevator faults, and notify associated safety staff and elevator maintenance staff in time, repaired, reduce elevator
The incidence of safety accident.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that.
A kind of hoist ropes disconnects early warning fall arrest elevator counterweight, including be installed on the inside of counterweight frame to weights stack,
The counterweight frame upper end is connected with carrying means, and the carrying means include rope hitch plate and main horseline group, the main horseline
Group includes vertical hoist ropes and a pair of lateral hoist ropes, the rope hitch plate digs from top to bottom have it is multiple connect hole, it is described vertically
Hoist ropes runs through with lateral hoist ropes lower end to be connected Kong Bingyu counterweight frame upper end and is fixedly connected, and the vertical hoist ropes is fixed to be connected
It is connected at counterweight frame upper end center, a pair of lateral hoist ropes is located at left and right sides of vertical hoist ropes and about vertically draging
Messenger is symmetrical, and the carrying means further include auxiliary hoist ropes group, the auxiliary hoist ropes group include it is a pair of assist hoist ropes, one
The auxiliary hoist ropes lower end is also extended through and connects Kong Bingyu counterweight frame upper end and is fixedly connected, and a pair of of auxiliary hoist ropes difference
It is positioned at vertical hoist ropes two sides and symmetrical about vertical hoist ropes, early warning mechanism, and early warning mechanism are connected on the rope hitch plate
It is connected with auxiliary hoist ropes group, this programme is additionally arranged auxiliary on the basis of the main horseline group of conventional lift counterweight and drags
Messenger group continues to provide traction effect using auxiliary hoist ropes group, simultaneously after original main horseline group surprisingly disconnects
Early warning is issued, warns occupant's elevator faults in time, and notifies associated safety staff and elevator maintenance staff in time, is robbed
It repairs, reduces the incidence of elevator safety accident.
Further, the early warning mechanism includes contact-making switch, alarm and warning lamp, and contact-making switch, alarm and
It is electrically connected between warning lamp, the contact-making switch is connected between a pair of of auxiliary hoist ropes, and the alarm and warning lamp are equal
It is connected to rope hitch plate upper end, a pair of auxiliary hoist ropes is relaxed state, and a pair of of auxiliary hoist ropes is located on the downside of rope hitch plate
Part be in contact, the contact-making switch is located at the position that a pair of of auxiliary hoist ropes is in contact, and the rope hitch plate upper end is also connected with
It is always on headlamp, it is described to be always on headlamp and the electric connection of early warning mechanism, it is always on headlamp and maintenance service personnel is facilitated to understand
Check carrying means；When main horseline group surprisingly disconnects, it is exceptionally straight that a pair assists hoist ropes to be located remotely from each other, and continues to provide traction work
With when a pair of auxiliary hoist ropes is located remotely from each other, contact-making switch is disconnected, at this point, alarm and police originally in the state that is short-circuited
Show that lamp is switched on, alarm and warning lamp issue early warning, warn occupant's elevator faults in time.
Further, described to be always on headlamp and warning lamp is located at that rope hitch plate is ipsilateral, and it is remote that the alarm is located at rope hitch plate
From the side for being always on headlamp, and the quality of alarm is equal to the quality sum for being always on headlamp and warning lamp, entire to guarantee
The balance of counterweight improves the stability of elevator operation.
Further, dirt-proof cover, the dirt-proof cover upper end and rope hitch plate are equipped between the counterweight frame and rope hitch plate
It is fixedly connected, the auxiliary hoist ropes is located on the inside of dirt-proof cover, and dirt-proof cover can effectively protect auxiliary hoist ropes and contact is opened
It closes and is corroded from external environment, running can be stablized at the time of emergency.
Further, the dirt-proof cover is made using transparent material, and dirt-proof cover surface is coated with anti-snearing
Layer, the dirt-proof cover that transparent material is made convenient for maintenance staff and related service personnel from it is external directly from the inside of it
