The invention provides an oil supplier for suspension cable of elevator and elevator with the oil supplier, and the suspension cable oil supplier can steadily and uniformly supply oil for the entire periphery surface of the suspension cable without hole blocking when supplying oil for the suspension cable. In order to realize the purpose, the invention referred oil supplier (9) for suspension cable of elevator is characterized in that: the oil supplier includes an oil storage tank (15), an oil supply pipe (16) for dripping oil and a flexible pipe (17) of oil supply pipe (16) stored in the oilstorage tank (15), the oil supply pipe (16) is structured on a pulley wheel (8) coiled with a suspension cable (6) of an elevator (1), and has an oil dripping hole (18) for dripping oil on the pulleywheel (8), and oil which is dripped on the pulley wheel (8) during rotation of the pulley wheel (8) is supplied to the suspension cable (6) coiled on the pulley wheel (8) by dripping oil on the pulley wheel (8) from the oil dripping hole (18).
Description
technical field [0001] The present invention relates to an elevator, in particular to an improved structure of an oil supply device for supplying oil to a sling used for the elevator. Background technique [0002] Conventionally, as the sling used to suspend the elevator car and the counterweight in the sling elevator, a wire rope sling with a hemp core is used. The role of lubrication between the sheave and the sling, and also plays the role of rust prevention. In recent years, however, steel core slings have been used more and more in elevators, and when such steel core slings are used, almost no oil seeps out from the steel core. For this, oil must be supplied to the sling from the outside of the sling. [0003] As a method of supplying oil, for example, manual oiling by a maintenance person may be employed at regular intervals. However, this method requires time and cost and may cause unevenness in the amount of oil supplied. In addition, as another method, a method o...
