Abstract

The present invention discloses a kind of instrument for dismantling lacing wire, is fixed including long-armed, described long-armed front end and end；The shape of the end is ellipse, and inside sets hexagon through hole；The long-armed lower end also sets up strut, and the strut is 2, and the strut is each attached on long-armed；Spring, the upper end of the spring and long-armed fixation are set in the inner space of 2 struts, and lower end and the bearing piece of the spring are fixed.It is an advantage of the invention that：In use, internal hexagon through hole is stuck in the tip of lacing wire, bearing piece on the outside of the lacing wire tip of neighbours with abutting；In this way, on the one hand lever principle can be utilized to improve torsion, on the other hand, due to not tapping lacing wire directly, lacing wire will not be caused to damage；And the setting of strut and bearing piece, torsion can be decomposed to two lacing wire tips, lacing wire is avoided to be subject to the torsion of bigger and destroy；And the setting of spring can buffer impact energy, and it is evenly distributed to two lacing wire tips.

Description

A kind of instrument for dismantling lacing wire

Technical field

The present invention relates to blast furnace staying replace supply air system when, for it is quick, it is convenient dismounting lacing wire a kind of special tool Tool.

Background technology

When blast furnace staying replaces supply air system dismounting lacing wire, typically now using instruments such as sledgehammers, labor intensity is greatly simultaneously And the take-down time is long, causes damping down time lengthening.In addition, directly being tapped using sledgehammer, the damage of lacing wire is often caused.

The content of the invention

In order to solve the above technical problems, the object of the present invention is to provide a kind of instrument for dismantling lacing wire, specific technical solutions It is as follows：

A kind of instrument for dismantling lacing wire, it is characterised in that：It is fixed including long-armed, described long-armed front end and end；It is described The shape of end is ellipse, and inside sets hexagon through hole；The long-armed lower end also sets up strut, and the strut is 2, The strut is each attached on long-armed；In the inner space of 2 struts set spring, the upper end of the spring with it is long-armed solid Fixed, lower end and the bearing piece of the spring are fixed.

It is an advantage of the invention that：In use, internal hexagon through hole is stuck in the tip of lacing wire, the lacing wire of bearing piece and neighbours It is abutted on the outside of tip；In this way, on the one hand lever principle can be utilized to improve torsion, on the other hand, due to not tapping lacing wire directly, no Lacing wire can be caused to damage；And the setting of strut and bearing piece, torsion can be decomposed to two lacing wire tips, lacing wire is avoided to be subject to bigger Torsion and destroy；And the setting of spring can buffer impact energy, and it is evenly distributed to two lacing wire tips.

Description of the drawings

Fig. 1 is the structural diagram of the present invention；

Fig. 2 is the view along long-armed end face direction；

Fig. 3 is the structure diagram of end and through hole.

Specific embodiment

The present invention is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1-Figure 3, the present invention includes long-armed 1, described long-armed 1 Front end is fixed with end 2；The shape of the end 2 is ellipse, and inside sets hexagon through hole 4；The long-armed lower end is also Strut 3 is set, and the strut is 2, and the strut 3 is each attached on long-armed 1；It is set in the inner space of 2 struts Spring 5, the upper end of the spring 5 are fixed with long-armed 1, and lower end and the bearing piece 6 of the spring 5 are fixed.

In use, internal hexagon through hole is stuck in the tip 7 of lacing wire, bearing piece 6 on the outside of the lacing wire tip of neighbours with abutting； In this way, on the one hand lever principle can be utilized to improve torsion, on the other hand, due to not tapping lacing wire directly, lacing wire will not be caused to damage It is bad；And the setting of strut 3 and bearing piece 6, torsion can be decomposed to two lacing wire tips, lacing wire is avoided to be subject to the torsion of bigger and break It is bad；And the setting of spring 5 can buffer impact energy, and it is evenly distributed to two lacing wire tips.Arrow direction in figure is The direction that external force applies.
