Abstract
The present invention relates to a towing system for a hydraulic lift, which can ensure the balance of a lift cage. The present invention comprises a supporting beam and four towing mechanisms, wherein the supporting beam is fixedly arranged on a lift well; the four towing mechanisms respectively correspond to the four corners of the lift cage; each towing mechanism is composed of an oil cylinder, a plurality of guiding pulleys and a towing rope and tows the three corners of the cage so as to simultaneously operate in a lifting mode. The system can ensure the balance of the lift cage and prevent heavy cargoes from eccentrically being loaded so as not to make the lift cage incline. Consequently, the friction resistance between guiding rails in the cage and the lift well is reduced. The guiding rails are spaced in the cage. Therefore, the guiding rails can not be damaged.
Description
The present invention relates to the trailer coupling of hydraulic elevator.
Hydraulic elevator in the prior art, the hoist ropes of its trailer coupling generally all are arranged on traction elevator cage operation on the medium position of lift car top.This mechanism is used in does not also have very problem on the elevator of little carrying capacity (for example below 5 tons), problem has just occurred on the elevator of big carrying capacity but use.Transport at the parcel car load and to transport lift car, particularly goods unbalance loading in lift car and get under the center of gravity of its deviation of gravity center lift car situation far away, car will certainly lack of equilibrium, produces.Be used for friction drag between the spacing guide rail of car when this inclination not only can increase elevator cage operation and in the elevator hoistways, and the time has been grown the damage that also causes guide rail easily.
How unbalance loading can not make the lift car generation tilt, guarantee the traction system of lift car energy balance movement no matter the purpose of this invention is to provide a kind of goods, to overcome the shortcoming of prior art.
The present invention realizes as follows.
The traction system of hydraulic elevator, comprise the strutbeam that is fixedly installed on the elevator hoistways, it is characterized in that this system also comprises the trailer coupling that install at four angles of four respectively corresponding lift cars, said each trailer coupling all comprises an oil cylinder that is fixedly mounted on the band assembly pulley on the strutbeam, and several also are installed in leading sheave and three hoist ropes on the strutbeam.Said wherein hoist ropes is burning assembly pulley and the leading sheave on the oil cylinder under this trailer coupling, one end and this trailer coupling the corner connection of corresponding lift car, the other end is connected with strutbeam, said another hoist ropes is around a leading sheave at the assembly pulley on the oil cylinder under this trailer coupling and the leading sheave trailer coupling place adjacent with it, the corner connection of the pairing lift car of trailer coupling that one end is adjacent with this, the other end is connected with strutbeam, said hoist ropes again is around a leading sheave at the assembly pulley on the oil cylinder under this trailer coupling and a leading sheave and its another adjacent trailer coupling place, the angle of the pairing lift car of trailer coupling that one end is adjacent with this is connected, and the other end is connected with strutbeam.
Technical scheme of the present invention is because the lifting operation is done at two three angles that make each trailer coupling in the traction system all draw lift car simultaneously.Obviously, unless hoist ropes fracture, otherwise goods unbalance loading how, how this traction system can not make lift car produce, it has overcome the problem that prior art exists.
The invention will be further described below in conjunction with accompanying drawing.
What accompanying drawing 1 provided is the theory structure scheme drawing of this hydraulic elevator traction system.
In the accompanying drawing: A is the compartment top of lift car, B, C, E, D are respectively four angles of lift car compartment top A, P is the strutbeam that hangs in the elevator room on the elevator hoistways, and F, G, J, H are four trailer couplings that respectively corresponding four angle B, the G of lift car compartment top A, F, D install.
The said trailer coupling that can guarantee lift box balance of this explanation, comprise the strutbeam P that is fixedly mounted on the elevator hoistways, it is characterized in that it also comprises trailer coupling F, G, J, H that four respectively corresponding four angle B, the C of lift car compartment top A, E, D install, said each trailer coupling F, G, J, H have same version, be that it comprises three hoist ropes 1,2,3, the oil cylinder 13 with the first leading sheave group 14 that is fixedly mounted on the strutbeam P is fixedly mounted on the second leading sheave F on the strutbeam P

5And H
4Three angles of the simultaneously equal traction elevator car roof A of said each trailer coupling, be the angle of the pairing lift car of this trailer coupling and two adjacent angles, its mode is: wherein hoist ropes 1 is walked around the first leading sheave group 14, the second leading sheave F on the oil cylinder 13 under this trailer coupling
1With the 3rd leading sheave F
6, the angle of an end and the pairing lift car of this trailer coupling is fixedly linked, and the other end and strutbeam P are fixedly linked, and said another hoist ropes 2 is walked around the first leading sheave group 14, the second leading sheave F on the affiliated oil cylinder 13 of this trailer coupling
2With the 3rd leading sheave G
5, an end and strutbeam P are fixedly linked, and an adjacent angular at the pairing lift car of the other end and this trailer coupling angle is fixedly linked, and said also hoist ropes 3 is walked around the first leading sheave group 14, the second leading sheave F on the oil cylinder 13 under this trailer coupling
3With the 3rd leading sheave H
4, an end and strutbeam P are fixedly linked, and another adjacent angular at the pairing lift car of the other end and this trailer coupling angle is fixedly linked.When the hoist ropes of each trailer coupling is walked around each leading sheave, for preventing that friction mutually takes place between the hoist ropes disturbs adjustment upper and lower, front, rear, left and right that the position of second, third leading sheave can be done.
