Description
Technical field
The utility model relates to a kind of elevator supplemental measurement tool, particularly relates to a kind of elevator traction sheave grooving wearing capacity measuring tool.
Background technology
The most popular type of drive of elevator is tractive driving.As shown in Figure 1, the principle of work of tractive driving is: wire rope connects car 2 by one end of elevator traction sheave 1, and the other end connects pouring weight 3, car 2 with to the gravity of pouring weight 3, traction steel-cable is pressed in the grooving of elevator traction sheave 1.Motor rotates, and due to the friction force between the grooving of elevator traction sheave 1 and wire rope, drives car 2 to move up and down in hoistway.
In the use procedure of elevator, unavoidably there are wearing and tearing in traction sheave and wire rope." inspection of TSGT7001-2009 elevator surveillance and periodic inspection rule " clearly proposes: traction sheave grooving must not have heavy wear.Therefore, must change the traction sheave that may wear to a certain degree and wire rope.Wearing and tearing unevenness between grooving is the condition that traction sheave is changed, but, there is no that a set of easy and simple to handle, precision is reliable, the traction sheave wearing capacity measuring tool of highly versatile so far, only have the akin traditional measurement tool and method of the following two kinds:
1, " GBT13435-1992 elevator traction machine "
The method straight steel ruler, measures the distance of each standard round capital to angle square.There is following defect in the method:
1), precision is not high: need to adopt straight steel ruler to measure spacing in addition, the reading of measuring position and operator is accustomed to all will affecting precision;
2), operating process is loaded down with trivial details: first need lay angle square, then place multiple standard cylinder, then adopt ruler to measure, survey instrument is various, and integrated level is not high, and measuring process is miscellaneous;
3), bad adaptability: in-site measurement can not take off wire rope, and need be with to carry and measure, standard cylinder cannot be placed, and measurement cannot be carried out, and in-site measurement is inapplicable.
2, the patent No. is " CN200820150830 ", name is called the utility model patent of " a kind of abseiling groove wearing capacity measuring tool "
The measuring method of this patent is: be first positioned in unworn grooving by survey instrument and position, by No. 11 unworn grooving gabarits of parts record in this patent Fig. 3, again this instrument is placed in the grooving worn and torn, to record in this patent Fig. 3 the distance that No. 17 parts stretch out No. 11 parts, be wear extent.There is following defect in this patent:
1), bad adaptability: the grooved of elevator traction sheave grooving has 3 kinds, and the method can only survey half slot, and the wear extent of other this two kinds of grooveds cannot be measured;
2), poor universality: in this patent, the diameter of No. 11 parts can not regulate, but the diameter of elevator rope from
arrive
not etc., this instrument can not measure all groovings;
3), measuring condition is harsh: this instrument needs first to locate in unworn grooving, and elevator building-site will look for the unworn grooving of same model, is almost impossible.
