Counterweight frame has one side to dispose by well enclosure, for the convenience of installation, adjustment, inspection in computer room and hoistway, safety tongs pull rod
It should be arranged on one or two of two angles of non-wall side.
Another preferred embodiment according to the present utility model is arranged two counterweight safeties, is respectively arranged not
On same counter weight guide track.Preferably, a safety tongs trigger mechanism, the touching of the two safety tongs are configured for each counterweight safety
The balance element of hair mechanism is connected by connector, and by directive wheel pull rod all companies of being fixed on of two safety tongs trigger mechanisms
On fitting, as long as so that connector can all be pushed by having one of directive wheel pull rod to move, and then mobile security pincers pull rod is to touch
Send out counterweight safety.It is also conceivable to multiple public safety tongs trigger mechanisms of counterweight safety, pacify in multiple counterweights
Linkage is set between full pincers and the linkage is connected with safety tongs trigger mechanism.When directive wheel triggering safety tongs triggers machine
After structure, safety tongs trigger mechanism triggers linkage, and then the linkage makes multiple counterweight safeties simultaneously clamp on counterweight
Guide rail.
In addition, the utility model further relates to a kind of home lift, which has pair according to design described above
Weight anti-fall device.
Detailed description of the invention
Elaborate preferred embodiment according to the present utility model with reference to the accompanying drawing.Attached drawing are as follows:
Fig. 1 shows the schematic diagram with counterweight anti-fall device according to the present utility model.
Specific embodiment
One kind is shown in FIG. 1 for elevator, particularly for the schematic diagram of the counterweight frame 3 of home lift.In the counterweight
The directive wheel 4 for winding steel cable is disposed on frame 3, the steel cable is for connecting counterweight frame and carriage.According to the present utility model
In embodiment, counterweight anti-fall device is installed on counterweight frame 3, it includes: counterweight safety 5 and safety tongs trigger mechanism 2.Peace
Full pincers trigger mechanism 2 is connected with directive wheel 4 and counterweight safety 5 respectively, so that directive wheel 4 can be with counterweight safety
5 linkages, the i.e. movement of directive wheel 4 can trigger counterweight safety 5.
If steel cable is broken, directive wheel 4 can drop under the effect of gravity, and directive wheel 4 pulls safety tongs triggering
Mechanism 2, so that safety tongs trigger mechanism 2 triggers counterweight safety 5, counterweight safety 5 clamps counter weight guide track, to prevent counterweight
Tenesmus.
Safety tongs trigger mechanism 2 according to the present utility model includes directive wheel pull rod 6, balance element 7 and safety tongs pull rod
1.As shown in Figure 1, safety tongs trigger mechanism 2 is similar to a kind of lever construction.6 one end of directive wheel pull rod and the fixed company of directive wheel 4
It connects, the other end is then hinged on the end of balance element 7；1 one end of safety tongs pull rod is connect with counterweight safety 5, and the other end is hinged
On the end opposed with directive wheel pull rod 1 of balance element 7.Balance element 7 is then supported on counterweight frame 3.If steel cable occurs disconnected
It splits, directive wheel 4 moves down under gravity forces, one end of balance element 7 is pulled by two directive wheel pull rods 6, due to thick stick
Bar effect, the other end of balance element 7 are lifted up safety tongs pull rod 1, and safety tongs pull rod 1 triggers counterweight safety 5, so that right
Weight safety tongs 5 clamps counter weight guide track, to play the role of that counterweight frame 3 is prevented to drop.It is preferred that being set on each counter weight guide track
The safety tongs trigger mechanism 2 setting counterweight safety 5 and matching therewith.Additionally it is contemplated that multiple counterweights are safe
Pincers 5 share a safety tongs trigger mechanism 2, setting linkage and the linkage and peace between multiple counterweight safeties 5
Full pincers trigger mechanism 2 is connected.After directive wheel 4 triggers safety tongs trigger mechanism 2, safety tongs trigger mechanism 2 triggers linkage,
And then the linkage makes multiple counterweight safeties 5 simultaneously clamp on counter weight guide track.
