Abstract

A prompt system for quickly positioning a cart mechanism of a casting crane comprises an induction iron, a proximity switch, an indicator light and a buzzer. A proximity switch is arranged on the crane, and then an induction iron is welded on the walkway beam at each fixed station where the crane lifts molten steel; an indicator light and a buzzer are arranged in a driver room. When the proximity switch on the crane senses the induction iron signal, the indicator lamp in the cab is turned on, the buzzer gives an alarm, the crane enters an accurate station, and the crane directly falls down to the molten steel tank. Through the intuitive prompt system, the time for positioning and adjusting the crane driver and the crane mechanism is reduced, and the operating efficiency of the crane is improved.

Description

Prompt system for quick positioning of cart mechanism of casting crane

Technical Field

The utility model belongs to hoisting equipment relates to one set of prompt system that can fix a position fast to casting crane cart mechanism.

Background

The crane is equipment which is matched with a cart running system, a trolley running system and a lifting system to carry out lifting work in a factory building. In steel enterprises, casting cranes are mainly used for lifting molten metal tanks at ordinary times. The hoisting of these metal cans from one station to another requires alignment, fine manipulation by the crane operator. The driver can easily tip over the molten steel when the alignment is not accurate, or the steel-making production rhythm is influenced by the slow alignment speed. The driver usually aligns mainly by remembering some reference points on the factory building beam to match with each station on the ground, and then slowly adjusts the cart position to accurately position. The choice of reference point is influenced by the field lighting conditions and the subjective awareness of the driver. The accurate reference point plays a critical role in quickly positioning the crane cart mechanism.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a prompt system that one set of casting crane cart mechanism was fixed a position fast, the help driver fixes a position fast to accurate station, improves the work efficiency of crane.

The utility model adopts the technical proposal that:

a quick positioning prompt system of a casting crane cart mechanism comprises induction irons, a proximity switch, an indicator light and a buzzer, wherein the proximity switch is installed on a crane, and one induction iron is welded on a walkway beam at each fixed station where the crane lifts molten steel; an indicator light and a buzzer are arranged in a driver room.

The use principle is as follows: when the proximity switch on the crane senses the induction iron signal, the indicator lamp in the cab is turned on, the buzzer gives an alarm, the crane enters an accurate station, and the crane directly falls down to the molten steel tank.

The utility model has the advantages that: the design of the visual prompt system reduces the positioning and adjusting time of a crane driver cart mechanism and improves the operating efficiency of crane operation.

Detailed Description

The following further describes the embodiments with reference to the drawings.

FIG. 1 shows: quick location reminder system of casting crane cart mechanism, including response iron (2), proximity switch (1), pilot lamp (3) and bee calling organ (4). A proximity switch (2) is arranged on the crane, and then an induction iron (1) is welded on a walkway beam at each fixed station where the crane lifts molten steel; an indicator light (3) and a buzzer (4) are arranged in a driver's cab.

The use principle is as follows: a round gasket with the inner diameter larger than 32 is welded at one end of a 40-degree angle steel to be used as a base. The whole is welded on a cart beam, and the proximity switch (1) is arranged on a circular gasket. Then the crane is driven to a working position, and an induction iron (2) is welded on the walkway beam right below the proximity switch (1). And the induction irons (2) of all stations are welded by analogy. A cable is arranged to connect the proximity switch (1) and the cab. The indicating lamp (3) and the buzzer (4) are arranged at the upper left corner of the cab, so that the driver can observe conveniently. The intermediate relay and the air switch are installed to an electric box in a cab.

FIG. 2 shows: q1 is an air switch, SQ1 is a proximity switch, K1 is an intermediate relay, H1 is an indicator light, and B1 is a buzzer. When the proximity switch SQ1 senses an induction iron signal, the coil of the K1 is electrified and the intermediate relay is attracted, the indicator lamp H1 is lightened, and the buzzer B1 gives an alarm to prompt a driver that the driver has arrived at an accurate station at present.
