Description

Apparatus for confirming the open and close state of the hopper gate using in the unloader}

The present invention relates to a device for checking the opening and closing state of the hopper gate for cutting out a certain amount to the lower line after loading the raw material entered through the vessel to the hopper using the basket of the unloading machine, and more specifically, the opening and closing state of the hopper gate The present invention relates to a device for checking the open / closed state of a hopper gate having a display device which operates in conjunction with the opening / closing operation of a hopper gate so that an operator of a cab can check.

In general, as shown in FIG. 1, the hopper gate 2 remains closed before the operator of the unloading machine A cab C starts to unload the raw material from the vessel. At this time, when the unloaded raw material is loaded about 40% in the hopper 1, the operator gradually opens the hopper gate 2 to supply the raw material to the lower line by a predetermined amount.

On the other hand, the open state of the hopper gate 2 is made by the operator adjusts the hopper gate 2 in the cab (C), the open state of the hopper gate 2 is completely (100%) open in the cab (C) Only the complete (100%) closure can be seen, and the opening and closing state of such a gate (2) can not be confirmed.

That is, when the raw material transported through the vessel is unloaded to the hopper 1 using the basket (B) device, as shown in Figure 2, the operator of the cab (C) is not visible at the bottom using the push button By physically adjusting the opening and closing state of the hopper gate 2 does not cut a certain amount of raw material.

At this time, the operator does not check the operation of the hopper gate 2, but can only know the full (100%) open or completely closed of the hopper gate (2).

Therefore, if the hopper gate 2 is opened too much by the operator's arbitrary operation, a large amount of raw material is poured at a time, causing an overload on the belt conveyor which is the conveying means in the unloading machine A, and If work is done at the same time, it can cause damage to the lower line.

In addition, when the hopper gate 2 is operated using the force of the motor, the wire rope 3 is used. When the hopper gate 2 is operated by the rope 3, if the lower line is stopped, the deflection of the wire 3 occurs only when the hopper gate 2 is closed, and the substantial gate 2 is operated. Will not work.

Therefore, various problems, such as the hopper gate 2 is suddenly activated when the lower line is operated, the wire 3 is derailed.

That is, the unloading operation of the steel raw material is continuously loaded into the hopper by moving the basket of the unloading machine, which is loaded on the belt conveyor in the unloading machine through the feeder and the hopper gate, and passes through the ground belt conveyor to be loaded on the yard (YARD).

At the start of the unloading operation, the hopper gate is kept in a closed state, after which the hopper gate is gradually opened to adjust the amount of unloading of the raw material.

On the other hand, the driver is using the push button that is often operated by the driver to control the amount of loading during unloading operation, the operator is operatively controlling the opening and closing state of the hopper gate, but the operator can not confirm the exact opening and closing state, the following problems occur It is becoming.

That is, during the operation of the hopper gate pushbutton to adjust the unloading capacity, the movement of the hopper gate cannot be confirmed, and the hopper gate delivered to the motor operates at a too high speed so that the amount of cutting out of the raw material can be poured at once. There is no open status sign, resulting in insufficient equipment and dispensing.

The present invention has been made to solve the conventional problems as described above, consisting of a hopper gate, a hydraulic cylinder, a hydraulic pipe, a weight, a water pipe, a knit engraved on the outer surface to determine the open state of the hopper gate By keeping within the field of view of the cab, the driver can check the open or closed state of the hopper gate, thereby opening and closing the unloader hopper gate, which prevents the overload of the belt conveyor in the unloading machine and eliminates various problems in the lower line. The purpose is to provide a status check device.

In addition, in order to solve the above problems, the present invention is to be able to close the hopper gate even when the lower line stops to eliminate the various problems such as wire drum derailment in advance, the unloading hopper which can improve the unloading working environment of the operator It is an object of the present invention to provide an apparatus for checking the open / close state of a gate.

According to an embodiment of the present invention, in order to achieve the above object, to confirm the opening and closing state of the hopper gate operated by the driver of the unloader by operating the pushbutton in the cab to discharge the steel raw material unloaded from the ship to the hopper The device includes hydraulic means for hydraulically operating the hopper gate up and down by manipulating the pushbutton, a weight connected to the hopper gate so as to move up and down in conjunction with the up and down operation of the hopper gate, and the additional accommodation. It consists of a fluid storage tank in which a fluid is stored in the space, and a case in which fluid communication with the fluid storage tank is possible, and a case having a seal with a graduation engraved on the outer surface is installed therein, the operation of the hydraulic means As the hopper gate is operated by the addition in conjunction with this The fluid in the fluid storage tank flows to the case so that the float moves up and down together with the shangdong of the weight.
