Description
Technical field
The present invention relates to the balanced compensated chain technical fields of elevator, more particularly to a kind of installation elevator that is suitable for be mended with balance
Repay the device of chain.
Background technique
Elevator at runtime, the carriage of elevator by wirerope and opposite to reconnection, when carriage is in top layer, steel wire
Rope is just in counterweight-side, and counterweight-side is with regard to more weight of wirerope；When carriage is in bottom, wirerope is just in cage side, cage side
With regard to more weight of wirerope, wirerope can generate dynamic imbalance with the continuous up and down motion of elevator, so needing to use
Chain is compensated to compensate the weight of wirerope, this part drop is balanced, makes elevator even running；It is greater than at present in vertical lift distance
In 30 meters of elevators, balanced compensated chain is to ensure that the important equipment of elevator operation stability and safety, the operation meeting up and down of elevator
Balanced compensated chain is set also to move up and down therewith.Due to the feature of balanced compensated chain itself flexibility, can be produced in upper and lower operational process
The horizontal jitter of raw certain amplitude, therefore, it is necessary to an auxiliary devices, can play guiding role, avoid and other elevator portions
Part interference, while the excessive shaking of balanced compensated chain can be prevented again, reduce noise and the vibration of generation.
Common currently on the market there are three types of forms: one kind being ring-shaped guiding device, and inside is equipped with rolling element, and balance is mended
Chain to be repaid to extend there through, rolling element fences up balanced compensated chain, a space for example, four orthogonal directive wheels are encircled a city,
Balanced compensated chain shuttles wherein, defines balanced compensated chain activity space, to be effectively prevented balanced compensated chain swing, mentions
The stationarity of high elevator；Second is lever and block roller formula, and lever and block roller is arranged in the lower section of counter weight guide track or car guide rail,
Make balanced compensated chain not to swinging among carriage and counterweight, in the prior art, a kind of compensation chain of vertical lift elevator is led
To device, it wraps up plastic bushing using compensation chain guide bars outer surface, is separately fixed on two counterweight guide rails, thus
The shaking for reducing carriage, mitigates the abrasion of components；The third structure is mended by the guide groove limiting balance on double directive wheels
The movement of chain is repaid, which accelerates the mill of balanced compensated chain due to contacting when balanced compensated chain works normally with guiding device
Damage.The characteristics of these types of guiding device is rigidity guiding, and structure coats buffer unit (such as rubber using the part outer surface of rigidity
The flexible materials such as glue, polyurethane), the movement of balanced compensated chain is oriented to, while guiding device is bolted, welds
Etc. on the basis of fixed forms are fixed on.This rigidity guiding device has the disadvantage in that guiding device rigid first mends balance
It repays in chain a certain range in the horizontal direction and shakes, if keeping the shaking of balanced compensated chain bigger due to load etc., put down
The hard collision of weighing apparatus compensation chain and guiding device will be bigger, can generate more collisions, noise and vibration.
Summary of the invention
To overcome the hard collision of balanced compensated chain and guiding device existing in the prior art will be bigger, can generate
More collisions, noise and vibration problem, the device that the present invention provides a kind of suitable for installing balancing compensation chain for elevator additional.
