As shown in Figs. 1-2, the two sides of counterweight 1 are provided with the guide part 12 matched with guide rope 2, and guide rope 2, which runs through, leads
To part 12.Guide rope 2 is the rope part that wirerope 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 is additionally provided with the counterweight guide part 5 matched with counterweight 4, to prevent counterweight 4 from shaking.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 are the guide rail matched with 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, the baffle matched with detection device 6 is fixed on brute spring.
As shown in Figs. 1-2, the lower part of hoistway 10 is provided with the anti-tipping apparatus 3 matched with counterweight 1 in the present embodiment,
When 1 complete compression buffer 7 of counterweight, traction rope 9 is in slack rope state, may result in the inclination of counterweight 1, 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 greater than 0, as shown in Fig. 3 or 5,
Elevator operates normally 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 located 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 working principle of the counterweight system for elevator of the utility model 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 tensioning state
Counterweight 4, be provided with the counterweight guide part 5 to match with counterweight 4 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, and when L is greater than 0, elevator is operated normally；
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 security level, then can be filled using more sensitive detection
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 limit value or is greater than upper limit value, detection device 6 is acted, and elevator is out of service.
When building needs to install additional elevator, but when available space deficiency, Elevator weight sensor design can concede space, in addition cloth
It sets in the hoistway separated with carriage.Since such counterweight is individually arranged in hoistway, the requirement of operation stability is without electricity
Height when terraced carriage is together with counterweight.So will be oriented to originally using guide rail guiding counterweight by elastic string body in the utility model
Counterweight substitution, because can under the premise of not influencing safety with more economy than metal guide rail guiding using rope body guiding
Reduce equipment cost, energy conservation and environmental protection.
A kind of counterweight system for elevator of the utility model, it is reasonable in design, be provided with prevent because guide rope extend or
Fracture is 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
In circuit, switch motion can disconnect circuit immediately, and elevator is out of service, economical and practical, high safety and reliability, guarantee counterweight
The space that counterweight system is occupied can be effectively reduced under the premise of system safety operation, and it is lesser to be particularly suitable for available space
In occasion.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
