Abstract

The utility model discloses a rope pressing device of a lifting mechanism. The rope pressing device of the lifting mechanism comprises a base seat, a press roller support, press rollers and an elastic mechanism, wherein the press roller support is assembled on the base seat in a leftward and rightward swaying mode, the press rollers are rotatably assembled on the press roller support and are used to press tightly steel wire ropes located on a steel wire rope rolling drum, and the elastic mechanism exerts the moment swaying leftwards to the press roller support to enable the press rollers to press tightly the steel wire ropes located on the steel wire rope rolling drum. The rope pressing device further comprises a limiting switch which is arranged on a rightward swaying stroke of the press roller support and is used to be triggered to control the stop of the lifting mechanism by the press roller support when the press rollers are separated from the steel wire ropes located on the steel wire rope rolling drum. When the press roller support in the rope pressing device drives the press rollers to sway rightwards, the press rollers do not press the ropes, the press roller support touches the limiting switch at the moment, the lifting mechanism is enabled to stop working, and therefore the lifting mechanism is guaranteed to work safely.

Description

A kind of rope press device of lifting mechanism
Technical field
The utility model relates to a kind of rope press device of lifting mechanism, belongs to the elevator machinery technical field.
Background technology
Steel rope in the lifting mechanism generally be single layer of rings on reel, steel rope is easily rope skipping or disorder cable in use, and shortened the service life of steel rope.For preventing that the phenomenon of disorder cable or rope skipping from appearring in steel rope in use, uses rope press device spacing to steel rope usually.
The Chinese patent notification number is that CN202148161U, name are called and disclose a kind of rope press device in " pressure rope device of hoisting reel ", this rope press device comprises two pedestals, respectively connect a lever by bearing pin respectively on two pedestals, pull bar of captive joint on each lever, pull bar passes pedestal and between pull bar and pedestal stage clip is set, connect a wheel pressing shaft between the upper end of two levers, wheel pressing shaft is provided with a pinch roller.This rope press device in use, pinch roller is pressing steel rope on the reel by the groove that arranges on its circumferencial direction, pinch roller rotates under the folding and unfolding of steel rope drives on one side, the endwisely slipping of an edge wheel pressing shaft.When the stage clip in this rope press device and pull bar damage, lever will drive pinch roller and move to the direction away from cable drum, this moment, rope press device just can not play the effect of pressing rope, and lifting mechanism still continues operation, brought hidden danger therefore for the lifting mechanism safe operation.
Summary of the invention
The purpose of this utility model is to provide a kind of rope press device that can guarantee the lifting mechanism safe operation.
For achieving the above object, the utility model adopts following technical scheme: a kind of rope press device of lifting mechanism, comprise base, swing and be assemblied in pinch roller support on the base, rotation is assemblied in the pinch roller that is used for compressing the steel rope on the cable drum on the pinch roller support, the pinch roller support is applied left the moment that swings and makes pinch roller compress the elastic mechanism of the steel rope on the cable drum, and described rope press device also comprises and being arranged on the oscillating stroke that the pinch roller support swings to the right, be used for when pinch roller breaks away from steel rope on the cable drum being triggered by the pinch roller support and control the limit switch that stops the lifting mechanism operation.
Described limit switch is travel switch.
The oscillating stroke that swings to the right at the pinch roller support is provided be used to the switch bracket that described limit switch is installed, and this switch bracket is fixed on the described base.
Described pinch roller is two.
The outer circumference surface of described pinch roller is provided with spiral groove.
The rope press device of the utility model lifting mechanism in use, elastic mechanism applies left the moment that swings to the pinch roller support and makes pinch roller compress steel rope on the cable drum, when the wheel of the pinch roller supporting band dynamic pressure in the rope press device swings to the right, pinch roller is not just pressed rope, this moment, the pinch roller support can touch limit switch, make lifting mechanism out of service, thereby guarantee the lifting mechanism safe operation.
Further, limit switch is installed on the switch bracket, switch bracket is fixed on and is convenient on the base rope press device is assembled into integral structure.
Further, when being wound with two root steel ropes on the cable drum, two pinch roller cocoas being set making respectively two steel ropes spacing.
Further, steel rope can in the spiral groove of the outer circumference surface of pinch roller, make and press rope more reliable.
Description of drawings
Fig. 1 is the scheme drawing of the utility model embodiment;
Fig. 2 is the use constitution diagram of the utility model embodiment.
The specific embodiment
As depicted in figs. 1 and 2, the rope press device embodiment of the utility model lifting mechanism comprises pinch roller 2, base 6 and pinch roller support 3, pinch roller 2 rotates by wheel pressing shaft 1 and is assemblied on the pinch roller support 3, pinch roller support 3 is sleeved in the base 6 by bearing pin 5, be provided with pull bar 7 in the bottom of pinch roller support 3, between base 6 and pull bar 7, be provided with spring, spring applies the moment that swings left and makes pinch roller 2 compress cable drum 10 pinch roller support 3, the top that is positioned at pull bar 6 at pinch roller support 3 is provided with banking stop 8, and this banking stop 8 is bolted with base 6.The rope press device of present embodiment also comprises limit switch 4, limit switch 4 is used for being triggered by pinch roller support 3 when pinch roller breaks away from steel rope on the cable drum 10 and control stops the lifting mechanism operation, limit switch 4 is installed on the switch bracket 9, and switch bracket 9 is fixed on the oscillating stroke that the pinch roller support 3 on the base 6 swings to the right.The pinch roller 2 of present embodiment is two, and the outer circumference surface of pinch roller 2 is provided with spiral groove, and certainly, in other embodiments, pinch roller also can be one, and pinch roller also can be common pinch roller of the prior art.
The rope press device embodiment of the utility model lifting mechanism in use with steel rope in the pinch roller groove of pinch roller 2, rotate by the coiling moving belt dynamic pressure wheel 2 of steel rope on cable drum 10, steel rope is compressed by pinch roller 2 in the lifting mechanism operational process, thereby prevent steel rope rope skipping or disorder cable.Spring applies left the moment that swings to pinch roller support 3 and steel rope that pinch roller 2 is compressed on the cable drums 10, when pinch roller support 3 drive pinch rollers 2 swing to the right, pinch roller 2 is not just pressed rope, pinch roller support 3 can touch limit switch 4 at this moment, make lifting mechanism out of service, thereby guarantee the lifting mechanism safe operation.
In other embodiments, limit switch can not be installed on the base by switch bracket, all can in the position that limit switch so long as be installed in is arranged on the oscillating stroke that the pinch roller support swings to non-cable drum direction.
