Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace iron hole blocking equipment, in particular to a taphole mud clamp. Background Art

[0002] When a steel plant is smelting iron, the tap hole at the bottom of the blast furnace will be opened. Before the next iron-making process, the tap hole will be sealed with cannon mud. During the process of blocking the tap hole, cannon mud needs to be put into the mud cannon machine.

[0003] In the process of throwing cannon mud, it is necessary to use a cannon mud clamp and a mechanical arm to clamp and drop the cannon mud. However, existing cannon mud clamps, such as the patent with announcement number CN114441005A, disclose a cannon mud clamp, which clamps the cannon mud by a combination of insertion and grasping. During the clamping process, since the clamp is a rigid structure and the cannon mud has a certain hardness, when the cone bar is inserted into the cannon mud, a reaction force is easily generated, causing the cone bar to deform or even damage the clamp, affecting the service life of the cone bar or the clamp.

[0004] In addition, when the gun mud clamp is working, the gun mud to be clamped needs to be positioned so that the jaws can be accurately inserted into the gun mud, but it is difficult for the jaws to land in the center. In the process of inserting the cone into the gun mud, the forces on the cones on both sides may be different due to the different landing points of the clamp and the hardness of the gun mud, causing the clamp to be subjected to a force moving to one side, further causing damage to the clamp.

One end of the offset limit rod 35 located inside the offset limit groove 34 is fixedly connected with a first stop block 36, and an offset reset spring 37 mounted on the surface of the offset limit rod 35 is fixedly connected between the first stop block 36 and the inner wall of the offset limit groove 34. The offset reset spring 37 can reset the movement of the clamp in the horizontal direction after the clamp clamps the gun mud.

[0030] See also Figure 6 The buffer assembly 2 includes a buffer limit rod 21 fixed to the bottom of the U-shaped plate 32, and also includes a buffer limit frame 22 sleeved on the surface of the buffer limit rod 21. The buffer limit rod 21 extends to one end of the buffer limit frame 22 and is fixedly connected to a second stop block 23. A buffer reset spring 24 sleeved on the surface of the buffer limit rod 21 is fixedly connected between the second stop block 23 and the inner wall of the buffer limit frame 22. The buffer reset spring 24 can reset the movement of the clamp in the vertical direction, and the vertical movement direction is perpendicular to the horizontal movement direction of the clamp caused by the offset assembly 3.

[0031] See also Figure 1 , Figure 7 The bottom of the buffer limit frame 22 is fixedly connected to a protective shell 4, and the top of the inner wall of the protective shell 4 is fixedly connected to a telescopic cylinder 5 whose telescopic end extends to the bottom thereof. The telescopic cylinder 5 can be a hydraulic cylinder, a pneumatic cylinder or an electric telescopic rod, etc. When a hydraulic cylinder or a pneumatic cylinder is used, it is connected to an external hydraulic or pneumatic system through a pipeline to supply hydraulic or pneumatic pressure to realize the telescopic function. The bottom of the protective shell 4 is fixedly connected to a fixed bracket 6, and a gun mud positioning and identification device can be installed on the fixed bracket 6 to identify and locate the gun mud so as to more accurately grab the gun mud, and the telescopic end of the telescopic cylinder 5 extends to the inside of the fixed bracket 6.

[0033] When in use, the external mechanical arm drives the clamp to move to the clamping position, and the telescopic cylinder 5 works to push the connecting plate 11 downward, so that the first connecting arm 12 and the second connecting arm 13 rotate, and then the cone spikes 14 on both sides are inserted into the cannon mud and clamped.

[0034] When the clamp is clamping the cannon clay, the clamp is subjected to an upward force, thereby driving the buffer limit frame 22 to move upward, further stretching the buffer limit spring 24. When the cannon clay is clamped, the buffer limit frame 22 moves downward under the action of the clamp's own gravity, the cannon clay gravity and the rebound force of the buffer limit spring 24. At this time, the buffer limit spring 24 may also be compressed.

[0035] When the clamp is clamping the cannon clay, lateral force will be generated due to the irregular shape of the cannon clay or the asymmetric insertion points of the cone spikes 14 on both sides. At this time, the clamp drives the U-shaped plate 31 to move laterally, and further drives the first stop block 36 to move through the offset limit rod 35, so that the two offset reset springs 37 in the offset limit groove 34 are stretched or compressed, providing lateral movement space for the clamp. After the cannon clay is clamped, the clamp returns to its original position in the horizontal direction under the action of the offset reset spring 37.
