The top of hoistway 10, which is provided with, is oriented to rope fixing part 8, and the upper end of guide rope 2, which is fixed on, to be oriented on rope fixing part 8；Well
The lower section in road 10 is pit 11, and the lower section that pit 11 corresponds to counterweight 1 is provided with buffer 7.
As shown in Figs. 1-2, the both sides of counterweight 1 be provided with 2 matched guide part 12 of guide rope, guide rope 2 is through leading
To part 12.Guide rope 2 is the rope part that steel wire rope or elastic material are constituted.Counterweight 1 by guide part 12 along guide rope 2 up and down reciprocatingly
Movement.
The lower part of hoistway 10 be additionally provided with 4 matched counterweight guide part 5 of counterweight, with prevent counterweight 4 shake.Counterweight is led
Fixed to part 5, counterweight 4 is moved up and down along counterweight guide part 5.As shown in Fig. 1, Fig. 3-4, the counterweight 4 in the present embodiment is
Clump weight, counterweight guide part 5 be with the matched guide rail of clump weight, between counterweight guide part 5 and clump weight formed T-type guide rail or
The guide rail forms such as dovetail guide.
Counterweight 4 is elastic component in further embodiments, and such as brute spring, counterweight guide part 5 is to be applied in elastic component
Guide rod or coat elastic component sleeve.As shown in figure 5, counterweight 4 is brute spring, counterweight guide part 5 is to be applied in strength bullet
Guide rod in spring, one end of brute spring are connected to the lower end of guide rope 2, and the other end is connected on counterweight guide part 5.Counterweight is led
It is fixed with detection device 6 on part 5, is fixed on brute spring and 6 matched baffle of detection device.
As shown in Figs. 1-2, in the present embodiment the lower part of hoistway 10 be provided with 1 matched anti-tipping apparatus 3 of counterweight,
When 1 complete compression buffer 7 of counterweight, traction rope 9 is in slack rope state, the inclination of counterweight 1 is may result in, if without overturning-preventing
Device 3, then counterweight 1 may topple over to cause danger.
The counterweight system for elevator of the present embodiment includes working condition and halted state：When counterweight system for elevator is in work shape
When state, counterweight 4 is located at the top of detection device 6, and the distance between detection device 6 and counterweight 4 L are more than 0, as shown in Fig. 3 or 5,
Elevator normal operation at this time；When counterweight system for elevator is in halted state, counterweight 4 is touched with detection device 6 or the bottom of counterweight 4
End is positioned at the top on 6 top of detection device, and the distance between detection device 6 and counterweight 4 L are less than or equal to 0, as shown in figure 4, at this time
Elevator is out of service.
The operation principle of the counterweight system for elevator of the present invention described in detail below：
As shown in Figures 3 and 5, the bottom end of the guide rope 2 of counterweight 1 is provided with for making guide rope 2 be always positioned at matching for tensioning state
It weighs 4, the counterweight guide part 5 to match with counterweight 4 is provided on hoistway 10 or in pit 11.
The distance between the bottom of counterweight 4 and 6 upper end contact of detection device are L, when L is more than 0, elevator normal operation；
After the guide rope 2 of elevator has used the regular hour or other etc. reasons, it is possible that guide rope 2 extend or fracture, make
The bottom for obtaining counterweight 4 is gradually reduced with the distance between the upper end contact of detection device 6 L, once the bottom of counterweight 4 touches inspection
The contact of 6 upper end of device is surveyed, i.e. L is less than or equal to 0, as shown in figure 4, then detection device 6 acts, elevator stops ensureing safety.
I.e. guide rope 2 is once relaxing or being broken, and detection device 6 can act immediately so that counterweight system and elevator are out of service, it is ensured that
Personnel safety and lift facility safety.
In some other practice, if desired higher safe class, then may be used more sensitive detection dress
6 are set, such as the equidistant sensor of infrared detector, sets the distance between the lower part of counterweight 4 and the top of detection device 6 L one
In fixed range, when actual range L is less than lower limiting value or is more than upper limit value, detection device 6 acts, and elevator is out of service.
When building needs to install elevator additional, but when free space deficiency, Elevator weight sensor design can concede space, in addition cloth
It sets in the hoistway detached with car.Since such counterweight is individually arranged in hoistway, the requirement of operation stability is without electricity
Height when together with terraced car and counterweight.So guide rail will be used to be oriented to counterweight in the present invention originally is oriented to counterweight by elastic string body
It substitutes, has more economy because being oriented to be oriented to than metal guide rail using rope body, under the premise of not influencing safety, can reduce
Equipment cost, energy conservation and environmental protection.
A kind of counterweight system for elevator of the present invention, reasonable in design, being provided with prevents from extending or being broken because of guide rope
To cause the detection device of safety accident, this detection device mechanical arrangement is simple, and electric switch need to only be connected on safety return circuit
In, switch motion can disconnect circuit immediately, and elevator is out of service, economical and practical, high safety and reliability, ensure counterweight system
The space that counterweight system is occupied can be effectively reduced under the premise of safe operation, be particularly suitable for the smaller occasion of free space
In.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention, all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
