Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace tapping machines, in particular to a shank quick connection device for a blast furnace tapping machine. Background Art

[0002] During the blast furnace ironmaking process, the blast furnace tapping machine is a critical piece of equipment ensuring proper iron tapping. Its primary function is to create a taphole in the furnace wall, allowing molten iron and slag to drain smoothly. During this process, the drill rod (typically a hexagonal steel drill), a key component of the tapping machine, must be frequently inserted and removed from the furnace wall to complete the taphole operation. However, in actual operation, the drill rod is prone to wear and breakage due to the high temperatures, high pressures, and erosion from the slag, necessitating regular replacement.

[0003] To quickly secure and replace the steel drill, existing technical solutions typically use a connecting sleeve to connect the rock drill to the steel drill. However, in this traditional connection method, the end of the steel drill needs to be firmly welded to a threaded connecting rod, which is then secured to the connecting rod and the sleeve using a threaded connection. While this fixing method can meet production needs to a certain extent, it has significant drawbacks. On the one hand, because the connecting rod and the steel drill are welded together once, if damaged or needs to be replaced, the connecting rod cannot be reused, resulting in material waste and increased production costs. On the other hand, each time the drill pipe is replaced, the threads must be tightened and loosened along with the connecting rod, which is time-consuming and labor-intensive, increasing the workload of the operator. Utility Model Content

[0004] In view of the problems in the related art, the utility model proposes a blast furnace tapping machine shank quick connection device to overcome the above technical problems existing in the existing related art.

[0005] To this end, the specific technical solutions adopted in this utility model are as follows:

[0006] A quick connection device for a shank of a blast furnace opening machine comprises a connecting sleeve, an assembly groove is provided inside the connecting sleeve, a steel shank is slidably installed inside the assembly groove, an adjustment groove is provided on one side of the assembly groove, a positioning groove is provided on one side of the adjustment groove, a connecting thread is provided on the inner wall of the positioning groove, a quick connection mechanism is provided inside the adjustment groove and on the surface of the steel shank, and a limiting mechanism is provided inside the connecting sleeve.

[0007] Furthermore, in order to press one end of the steel drill into the adjusting groove, the quick connection mechanism includes a compression spring fixedly connected inside the adjusting groove, one end of the compression spring is fixedly connected to a transmission partition, the transmission partition is slidably installed in the adjusting groove, and the assembly groove is connected to one end of the adjusting groove.

[0008] Furthermore, in order to achieve quick assembly and disassembly between the steel drill and the connecting sleeve, a limit ring is fixedly connected to one end of the outer surface of the connecting sleeve, a fixed ring is rotatably installed inside the limit ring, and a positioning pin is fixedly connected to one side of the surface of the steel drill.

[0009] Furthermore, in order to limit and fix the steel drill after installation, a limiting mechanism is provided inside the connecting sleeve. The limiting mechanism includes a screwing ring rotatably installed on one side of the connecting sleeve, and limiting plates are fixedly connected on both sides of the inner wall of the screwing ring. A shrinkage groove is opened on the side surface of the transmission partition, and the limiting plate cooperates with the shrinkage groove.

[0010] Furthermore, in order to facilitate the twisting and rotation of the twisting ring, rotating blocks are fixedly connected on both sides of the surface of the twisting ring, telescopic grooves are opened on both sides of the surface of the rotating block, and a telescopic spring is fixedly connected inside the telescopic groove. The end of the telescopic spring is fixedly connected to a limit rod, and the limit rod is slidably connected to the rotating block.

[0011] Furthermore, in order to achieve rotational limitation of the twisting ring, both sides of the surface of the connecting sleeve are fixedly connected with limiting cylinders, the limiting rod cooperates with the limiting cylinder, and the surface of the limiting rod is fixedly connected with an extrusion rod.

[0012] The beneficial effects of the utility model are as follows: when the steel drill is installed, by pressing the steel drill in the direction of the adjusting groove to shrink the compression spring, one end of the fixing ring is matched with the positioning pin on the surface of the steel drill, so that the steel drill is quickly installed in the connecting sleeve, and by twisting the screwing ring in the limiting mechanism, the limiting plate and the shrinkage groove on the transmission partition are staggered, so that the transmission partition limits and fixes one end of the installed steel drill, further improving the stability between the steel drill and the connecting sleeve. During disassembly, after the limiting plate is matched with the shrinkage groove on the transmission partition by twisting the ring, the steel drill is pressed into the adjusting groove again, and the fixing ring is removed from the positioning pin to complete the disassembly. The device can realize fast loading and unloading of the steel drill and the connecting sleeve when the steel drill is replaced, without the need to unscrew the connecting sleeve, effectively improving the replacement efficiency of the steel drill, and eliminating the manual welding process of the steel drill and the connecting sleeve, so that the connecting sleeve can be reused, effectively saving costs.

When the bolt 711 is in the unlocked position, the locking nut 708 is unlocked, and the locking nut 708 is unlocked, so that the bolt 711 can be unlocked easily.

[0027] like Figure 3-Figure 7As shown, a limiting mechanism 8 is provided inside the connecting sleeve 1 for further fixing the steel drill 3 installed on the connecting sleeve 1. The limiting mechanism 8 includes a screwing ring 801 rotatably installed on one side of the connecting sleeve 1. The inner walls of the screwing ring 801 are fixedly connected with limiting plates 802 on both sides. A contraction groove 803 is provided on the side surface of the transmission partition 702. The limiting plate 802 cooperates with the contraction groove 803. When one end of the steel drill 3 is installed in the connecting sleeve 1 through the quick connection mechanism 7, the screwing ring 801 is rotated to make the limiting plate 802 intersect with the contraction groove 803 on the transmission partition 702, thereby preventing the transmission partition 702 from sliding in the adjustment groove 4, thereby achieving stable limiting of the steel drill 3 installed in the connecting sleeve 1 and preventing the steel drill 3 from continuing to be squeezed after being compressed. Push the compression spring 701 to contract; the surface of the twisting ring 801 is fixedly connected with rotating blocks 9 on both sides, and telescopic grooves 10 are opened on both sides of the surface of the rotating block 9.
