Preferred pushing device main body 1 is divided into many parts in the horizontal direction, and the pushing device main body is connected with the various piece that is divided into respectively with hydro-cylinder 2.Embodiment when expression is divided into three parts with pushing device main body 1 in Fig. 4.Stereographic map with the cross section, two places of longitudinal direction in Fig. 4 is represented arc-melting equipment, and pair cross-section partly marks oblique line.Pushing device main body 1 is made of 1a, 1b, 1c, is connected with hydro-cylinder 2 with the pushing device main body respectively.A plurality of pushing device main body 1a, 1b, 1c drive simultaneously and carry out operation.For example, wait the obstruction that causes and under situation about limiting, also can carry out in addition pushing device main body 1b of confined part, the driving of 1c, can continue the operation of arc-melting equipment even produce by nipping of source of iron in the part of pushing device main body 1a.Restriction by the obstruction of pushing device main body 1 causes except the bottom of pushing device main body 1, also occurs in the both sides face of pushing device main body 1, therefore than being easier to the pushing device main body that confined position is two ends (being 1a, 1c under the situation of Fig. 4).Thereby, more preferably pushing device main body 1 is divided into more than three parts on the width (horizontal direction) with respect to the travel direction of pushing device main body for long-time continuous operation.In addition, cut apart several upper limits by decisions such as equipment restrictions, but the number of cutting apart below 8 is a comparison reality.In addition, the size of the pushing device main body that is divided into do not need all to equate, for example being divided under three parts the situation, can make central part big, makes that to be easy to confined both ends as described above little.And then, in each the pushing device main body that is divided into (under the situation of Fig. 4 for connecting the pushing device main body on the 1a~1c) respectively with hydro-cylinder 2, but with the pushing device main body that the pushing device main body that is divided into connects might not be corresponding with the quantity of hydro-cylinder with the quantity of the pushing device main body that is divided into, for example under the situation of cutting apart central part bigger, can make also that the number of cylinders that is connected with the pushing device main body of this part is a plurality of.
With reference to Fig. 1~3, expression uses the pushing device 10 of above-mentioned embodiment to melt the action of the pushing device 10 of source of iron when making molten steel in arc-melting equipment, and the effect of pushing device 10 each one is described.In addition, in this specification sheets and accompanying drawing, the integrant that has the identical function structure is in fact marked identical symbol and omits repeat specification.
Fig. 1 is that reinforced tapping end, the preheating chamber 6 that source of iron has been supplied to arc-melting equipment 5 and the state that carries out preheating, pushing device main body 1 kept out of the way the state that retreats limit position before the expression.The pushing device main body with hydro-cylinder 2 be in the shortest state (the shortening limit), the pushing device chassis is in the longest state (the elongation limit) with hydro-cylinder 4.
In common operation, the position that makes pushing device chassis 3 is certain position roughly, only makes the pushing device main body advance, retreat with hydro-cylinder 2, carries out the supply of source of iron 8 to smelting furnace 7.Then, be limited like this when unusual in pushing device main body 1, make pushing device chassis 3 advance, retreat the restriction of removing pushing device main body 1 with hydro-cylinder 4 with the pushing device chassis.
State from Fig. 1 begins operation and supplies with iron filings to melting chamber 7 in the following manner.At first, make the pushing device chassis drive the state that pushing device chassis 3 is advanced and become Fig. 2 towards (Return-ing direction) to it with what hydro-cylinder 4 shortened.For shortening the limit, pushing device chassis 3 is in maximum progressive position (limit of advancing) to the pushing device chassis with hydro-cylinder 4.Because advancing of pushing device chassis 3, the pushing device main body is also advanced with hydro-cylinder 2, and pushing device main body 1 is also advanced thus, and beginning is released source of iron 6 to melting chamber 7.When common operation from now on, pushing device chassis 3 is set at is positioned at this position.
Then, on the release direction, the pushing device main body is driven until the elongation limit with hydro-cylinder 2.Thus, pushing device main body 1 is advanced, and pushing device chassis 3 and pushing device main body 1 are positioned at the limit position that advances shown in Figure 3.
Like this, the miles of relative movement of pushing device 10 (stroke) becomes the pushing device main body is used the stroke of hydro-cylinder 4 with hydro-cylinder 2 and pushing device chassis total.The pushing device main body with the release of hydro-cylinder 2 towards with the pushing device chassis with the release of hydro-cylinder 4 towards being configured to oppositely, therefore no matter be pushing device main body 1 advance or situation about retreating under, can both drive with the power of same degree, even when taking place to stop up, also can the pushing device main body be retreated enough sufficient motivating forces, remove from restriction state easily.
By pushing device 10 is made structure as described above, can guarantee sufficient stroke, and the pushing device global design can be got compactly, also carry out the design that can be provided with under the situation about being restricted in the space that pushing device is set easily.
[embodiment 1]
With the same furnace capacity that is provided with pushing device of the present utility model of arc-melting equipment shown in Figure 1 be in the about 200 tons equipment, melt the test that iron filings are made molten steel.
Between the melting period of the fusing of carrying out iron filings, the position of pushing device chassis 3 is by making the pushing device chassis move, make pushing device chassis 3 to deciding that 500mm stove progresses inside is established with hydro-cylinder 4.Under this state, by making the pushing device main body with hydro-cylinder 2 action, carry out advancing, retreating of pushing device main body 1 repeatedly with the stroke of 2000mm, thus, the iron filings of supply preheating chamber 6 inside to melting chamber 7 in.
In addition, use control device to carry out connection, the disconnection of the driving of pushing device 10.
Pushing device main body 1 in operation, occurred and do not moved, though, can't remove the situation of the restriction of pushing device several times advancing, the pushing device main body being applied hydraulic pressure with hydro-cylinder 2 on the direction of retreat.In order to realize this releasing, the pushing device chassis is moved to the direction that pushing device main body 1 retreats with hydro-cylinder 4, thereby removed the restriction of pushing device main body 1.Reach the state that makes pushing device chassis 3 become the 500mm that advances once more, begin to make repeatedly advancing, retreat driving repeatedly and beginning the supply of iron filings of pushing device main body 1 once more.Thus, can continuous operation.
