CN201424351Y - Winch mechanism with the function of limiting super elevation and over speed - Google Patents

Abstract

The utility model discloses a winch mechanism with the function of limiting the super elevation and the over speed, relating to the structural improvement of the aluminum manufacturing winch mechanism, comprising a winch mechanism of an aluminum manufacturing vehicle; the winding drum of the winch mechanism is fixed on a bearing seat on the two sides by a winding drum shaft. The utility model hasthe characteristics that one end of the winding drum shaft is provided with a supporting shaft the external side of which is provided with an encoder, and the other end other supporting shaft is connected with the input shaft of a lifting height limiter arranged on the pedestal.

Description

Hoisting mechanism with superelevation, hypervelocity attributive function

Technical field:

The utility model relates to out the structural development of aluminium car hoisting mechanism.

Background technology:

Present hoisting mechanism owing to go out the too fast or superelevation of running velocity that aluminium car failure and other reasons causes, all can cause the great damage that the aluminium car in operational process.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of hoisting mechanism with superelevation, hypervelocity attributive function is provided.

For achieving the above object, the utility model adopts following technical scheme, the utility model comprises the hoisting mechanism of aluminium car, the reel of hoisting mechanism is fixed on two side shaft holders by drum shaft, its structural feature is that an end of drum shaft is provided with pivot shaft, pivot shaft is outward a coder, and the other end of pivot shaft links to each other with the input shaft of the lifting altitude killer on the base.

The beneficial effects of the utility model:

When reel of the present utility model rotated, coder and lifting altitude killer rotated with it simultaneously.In the rotation process of reel, the inner ring of coder and drum shaft are with changeing, coder sends pulse, coder rotates that fast more to send out pulse count many more, when the pulse count of unit time acquires a certain degree, by comparing with the value that sets in advance, determine whether to exceed default rotating speed, whether decision sends electric signal is taked brake measure.In the rotation process of reel, by the setting of lifting altitude killer, determine the number of turns of the forward and reverse rotation of reel, just determined the high-low limit position of lifting altitude.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is coder of the present utility model and dependency structure enlarged diagram.

The specific embodiment:

The utility model comprises the aluminium car, the reel 7 that goes out the aluminium car is fixed on two side shaft holders 8 by drum shaft 6, one end of drum shaft 6 is provided with pivot shaft 5, is coder 4 outside the pivot shaft 5, and the other end of pivot shaft 5 links to each other with the input shaft 3 of the lifting altitude killer 2 on the base 1.

Coder 4, lifting altitude killer 2 are the product that can purchase on the market.The model that coder 4 of the present utility model adopts is RHI90N-ONAK1R61N-1024, and the model of lifting altitude killer 2 is DXZ (B) 40:1-4.

Claims (1)

1, the hoisting mechanism that has superelevation, hypervelocity attributive function, comprise the hoisting mechanism of aluminium car, the reel of hoisting mechanism (7) is fixed on two side shaft holders (8) by drum shaft (6), an end that it is characterized in that drum shaft (6) is provided with pivot shaft (5), pivot shaft (5) is outer to be coder (4), and the input shaft (3) of the lifting altitude killer (2) on the same base of the other end (1) of pivot shaft (5) links to each other.
