Description
Technical field
The present invention relates to a kind of sling falling-proof device of elevator, it splits away off from pulley in order to the hoist cable that prevents to be wound on the pulley.
Background technology
In elevator, lifting body moves by the hoist cable that is wound on single or a plurality of pulleys, thus lifting in hoist trunk.Therefore, elevator must have the structure that can prevent that hoist cable from splitting away off from pulley.
For this reason, also be provided with sling falling-proof device in traditional elevator, when causing that because of reasons such as earthquakes big external force acts on the hoist cable, it prevents that hoist cable from running out of and splitting away off from pulley from the pulley grooves of pulley.For example, known have a solution, it splits away off from pulley for the hoist cable 1 that the angles that prevent to show greatly 180 degree are wound on the pulley, respectively near the hoist cable coiling notch portion of the hoist cable coiling notch portion of a side of pulley and opposite side, from the jut between the pulley grooves that is formed on peripheral pulley separate one be shorter than the hoist cable diameter size pole is set, perhaps the hoist cable that is wound on the pulley for the angles that prevent to show greatly 90 degree splits away off from pulley, near the hoist cable coiling notch portion of a side of pulley, from the jut between the pulley grooves that is formed on peripheral pulley separate one be shorter than the hoist cable diameter size flat board is set.
In the sling falling-proof device of above-mentioned traditional elevator, for the hoist cable that prevents to be wound on the pulley splits away off from pulley, and hoist cable is moved smoothly, and pole that will use as sling falling-proof device and flat board are mounted to from the jut between the pulley grooves that is formed on peripheral pulley and separate a size that is shorter than the hoist cable diameter.Therefore, when earthquake etc. takes place, if when having big external force to act on the hoist cable on the direction that makes hoist cable disengaging pulley grooves, then hoist cable may be stuck in the jut and the space between pole or the flat board that is formed on peripheral pulley, and the problem that hoist cable can't slide can occur.
Summary of the invention
The present invention be directed to that existing problem proposes in the above-mentioned conventional art, the object of the present invention is to provide a kind of sling falling-proof device of elevator, sling falling-proof device by this elevator, even when having big external force to act on the hoist cable, can prevent that also hoist cable from running out from pulley grooves.
To achieve these goals, the sling falling-proof device of the elevator of first aspect of the present invention is arranged on the pulley that periphery is formed with pulley grooves, split away off from pulley in order to the hoist cable that prevents to be wound on the pulley, wherein said pulley rotatably by pivotal support on the upper frame of elevator, it is characterized in that, hoist cable coiling notch portion in a side of described pulley is provided with at least one roller between the hoist cable coiling notch portion of opposite side, and described hoist cable is slided between described roller and described pulley, the sling falling-proof device of described elevator has pressing mechanism, this pressing mechanism supports described roller and described roller can be moved, and apply towards the pressing force of described pulley directive effect to described roller, described pressing mechanism is by constituting with the lower part: the long shape hole that forms at described upper frame; Be arranged at the spring pressing piece of described upper frame; Be inserted in movably in the described long shape hole, be used to support the roller shaft of described roller; And one end be installed on the described roller shaft, the other end is installed on the described spring pressing piece, will give spring to described roller towards the pressing force of the directive effect of described pulley.
In the sling falling-proof device of the elevator of the present invention with said structure aspect first, by clamping the hoist cable that is wound on the pulley, thereby can prevent that hoist cable from splitting away off from pulley with pulley and roller.So, make as the roller of swivel and the structure of hoist cable moving contact by employing, not only can guarantee that hoist cable smoothly moves, and the elimination basically that can make the roller that uses as sling falling-proof device be arranged in pulley side can cause hoist cable from the position in the gap that pulley grooves is run out, thus, even when having big external force to act on the hoist cable, can prevent that also hoist cable from running out from pulley grooves.Push towards the pulley direction by pressing mechanism and to be supported for the roller that can move, and clamp hoist cable, thereby can prevent that hoist cable from splitting away off from pulley with this roller and pulley.So, since pressing force that pressing mechanism produced by roller towards the pulley directive effect on hoist cable, so even when having big external force to act on the hoist cable, the sling falling-proof device of this elevator can prevent that also hoist cable from running out from pulley grooves.And, can also make to preventing to be wound on hoist cable on the pulley effectively to split away off required pressing force from pulley and act on the roller, guarantee that thus hoist cable carries out smoothly moving.
The sling falling-proof device of the elevator of second aspect of the present invention is characterised in that the outer peripheral portion at least of described roller has flexible.
In the sling falling-proof device of the elevator aspect second of the present invention with said structure, have flexible by the outer peripheral portion that makes roller, then roller can be under the state of closed contact and the hoist cable moving contact, so can elimination can cause hoist cable from gap that pulley comes off.
The invention effect
According to the present invention, can improve the safety of elevator, when causing that because of reasons such as earthquakes big external force acts on the hoist cable, can prevent that hoist cable from running out from pulley grooves.
