Description

A slag cleaning system with horizontal fishing function

technical field

The utility model belongs to the technical field of metallurgical machinery, in particular to a slag cleaning system with a horizontal fishing function.

Background technique

The aluminum electrolysis multifunctional crane unit is the key operating equipment for large-scale aluminum electrolysis production, and undertakes the task of assisting the production of large-scale prebaked anode electrolytic cells. With the development of electrolytic cell technology in the aluminum industry towards large-capacity pre-baked electrolytic cell technology, to ensure the modernization and high-efficiency stable production of pre-baked electrolytic cell, it is required that the aluminum electrolysis multifunctional crane has more complete functions.

Most of the existing aluminum electrolysis multifunctional crane slag removal systems use the hoisting mechanism to drive the lifting parts to lift through the wire rope or the single-stage hydraulic lifting structure, most of which are one-stage lifting. Due to the limited space of the plant equipment, the stroke is very limited; The closed track of the lower edge structure is arc-shaped, as shown in Figure 6, resulting in too many blind spots in the slag cleaning operation, and the cleaning effect can only be achieved through manual cooperation and multiple fishing, which greatly reduces production efficiency; and the hoisting mechanism The structure is complex, the maintenance is cumbersome, and it is easy to break down during the work process, resulting in safety production accidents.

Contents of the invention

The utility model aims at the above problems and provides a slag cleaning system with a horizontal fishing function which is simple in structure, stable and reliable, easy to maintain, and has a long service life.

In order to achieve the above purpose of the utility model, the utility model adopts the following technical scheme. The utility model includes a lifting mechanism with a lifting control system. The lower end of the lifting mechanism is provided with a grab mechanism. The grab bucket is characterized in that: a linkage arm is arranged on the side of the grab bucket, and the linkage arm is connected with the grabbing cylinder on the lifting mechanism; a connecting link hinged at one end to the middle of the linkage arm is arranged between the linkage arm and the lifting mechanism. The other end of the connecting rod is hinged with the lower end of the transmission rod through the pin shaft; the upper end of the transmission rod is provided with a stroke sensor connected with the lifting control system; the pin shaft is arranged in the elongated hole on the lifting mechanism.

As a preferred solution of the present utility model, the lifting mechanism includes a first-stage telescopic rod, on which a first-stage telescopic cylinder is arranged, the first-stage telescopic cylinder is connected with an intermediate telescopic rod, and an intermediate telescopic rod is provided on the intermediate telescopic rod. The air cylinder and the middle telescopic cylinder are connected with the final telescopic rod; the grasping cylinder, the grab mechanism and the long holes are all arranged on the final telescopic rod.

Beneficial effects of the utility model.

1. The utility model converts the arc motion of the grab bucket into a straight line motion at the elongated hole through the use of connecting rods, thereby facilitating the calculation of the running track of the grab bucket by the control system, and controlling the movement of the grab bucket device through the lifting system. Adjustment to realize the horizontal fishing of the grab bucket and improve the efficiency of slag cleaning.

2. The utility model detects the running track of the grab bucket through the connecting rod. The purely mechanical structure detection device can make the utility model more adaptable to the harsh environment, improve the service life of the utility model, and reduce the failure rate.

3. The utility model realizes the multi-level lifting of the system in the form of a telescopic cylinder and a telescopic rod, which has the advantage of saving space, and the utility model does not need to use a winch mechanism, so it is easy to maintain, simple in structure, and not prone to failure.
