Technical Field

[0001] The utility model relates to the field of belt conveyors, in particular to a drill rod suspension device for an iron notch opener with quick replacement. Background Art

[0002] At present, for the iron notch opener commonly used for opening the iron notch, in the process of drilling the iron notch, in order to prevent problems such as the deviation of the iron notch channel and the instability of the iron notch center, generally a set of drill rod suspension device (such as CN203462064U) for fixing the drill rod is installed at the front end of the iron notch opener. Since the drill rod suspension device is at the front end of the iron notch opener and close to the iron notch, during the process of the drill rod drilling into and withdrawing from the iron notch, the suspension hook at the front end of the drill rod suspension device is easily damaged by the splashed molten iron, not easy to replace, and the loss is relatively large. Content of the Utility Model

[0003] The purpose of the utility model is to provide a drill rod suspension device for an iron notch opener with quick replacement.

[0005] An upper slag baffle and a flat suspension hook are arranged up and down on the front end face of the front end plate. The upper slag baffle and the suspension hook are located in the same vertical plane and are arranged close to each other;

[0006] The upper slag baffle and the front end plate are detachably and fixedly connected through a first plug-in component. The first plug-in component includes a first pin shaft and a first pin plate. The first pin shaft has a head and a straight rod part. A first through hole for the straight rod part of the first pin shaft to pass through is opened on the upper slag baffle, and a second through hole corresponding to the first through hole is opened on the front end plate. The straight rod part of the first pin shaft sequentially passes through the first through hole and the second through hole, and a first pin plate fixing hole for the first pin plate to be inserted therein is arranged on the straight rod part of the first pin shaft extending out of the front end plate;

[0007] The suspension hook and the front end plate are detachably and fixedly connected through a second plug-in component.

Refractory materials are filled in the cavity formed by enclosing the slag baffle bottom plate and the slag baffle enclosures. In the specific implementation process, a first anchor is further provided on the surface of the slag baffle bottom plate on the side facing away from the front end plate.

[0014] Further, the suspension hook includes a suspension hook bottom plate, and a circle of suspension hook enclosures is arranged along the outer circumference on the surface of the suspension hook bottom plate on the side facing away from the front end plate. Refractory materials are filled in the cavity formed by enclosing the suspension hook bottom plate and the suspension hook enclosures.

[0024] The drill pipe suspension device of the utility model has two independent structures: an upper slag baffle 30 and a suspension hook 40. The upper slag baffle 30 can block the splashing molten iron and reduce the burning damage to the drill pipe 100. At the same time, since the suspension hook 40 is closer to the taphole than the upper slag baffle 30 and is more likely to be burned, the suspension hook 40 or the upper slag baffle 30 can be selectively replaced according to their different degrees of burning damage. Moreover, compared with the integrally formed structure of the upper slag baffle 30 and the suspension hook 40, the overall suspension hook 40 is not too bulky, reducing the difficulty of replacement. In addition, the upper slag baffle 30 and the suspension hook 40 are respectively detachably and fixedly connected through a first plug-in component 50 and a second plug-in component 60, and the plug-in assembly method is more convenient for disassembly.

[0025] Further, as Figure 2 , Figure 4 shown, two first through holes 300 are spaced left and right on the upper slag baffle 30, and each first through hole 300 is correspondingly provided with a set of the first plug-in component 50. At this time, the upper slag baffle 30 is fixed more reliably. Of course, the number of the first plug-in components 50 is not limited to one set or two sets, and can be adjusted according to needs as long as the fixation of the upper slag baffle 30 can be achieved.

[0026] Further, in combination with Figure 1 , Figure 3 and Figure 4 , the first pin plate 52 is a trapezoidal plate, which is convenient for achieving a tight fit with the first pin shaft 51 when inserted into the first pin plate fixing hole 510. Of course, the first pin plate 52 can also be a rectangular plate.

[0027] Further, as Figure 2 shown, two third through holes 400 are spaced left and right on the plate-shaped base of the suspension hook 40, and each third through hole 400 is correspondingly provided with a set of the second plug-in component 60, and the fixation is more reliable. At this time, the suspension hook 40 is fixed more reliably. Of course, the number of the second plug-in components 60 is not limited to one set or two sets, and can be adjusted according to needs as long as the fixation of the suspension hook 40 can be achieved.

[0028] Further, in combination with Figure 1 , Figure 3 and Figure 4 , the second pin plate 62 is a trapezoidal plate, which is convenient for achieving a fixed fit with the second pin shaft 61 when inserted into the second pin plate fixing hole 610. Of course, the second pin plate 62 can also be a rectangular plate.

Refractory material 33 is filled in the cavity formed by enclosing the slag baffle bottom plate 31 and the slag baffle enclosures 32. In the specific implementation process, as Figure 2 , Figure 3 shown, a first anchor 34 is further provided on the surface of the slag baffle bottom plate 31 on the side facing away from the front end plate 20. The first anchor 34 can be a circular flange surrounding the first through hole 300. Of course, the first anchor 34 can be any convex structure.

[0030] Further, in combination with Figure 2 and Figure 3 , the suspension hook 40 includes a suspension hook bottom plate 41 and a circle of suspension hook enclosures 42 are arranged circumferentially along the outer periphery on the surface of the suspension hook bottom plate 41 on the side facing away from the front end plate 20. Refractory material 43 is filled in the cavity formed by enclosing the suspension hook bottom plate 41 and the suspension hook enclosures 42.
