Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings in combination with the embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The specific implementation mode is as follows: referring to fig. 1-4, a hydraulic swing mechanism for a blast furnace comprises a swing cantilever 2, and a mud beating unit 3 is arranged at one end of the swing cantilever 2. The device also comprises a base 1, wherein the base 1 is fixed on the ground. The base 1 is provided with a first rotating shaft 11 and a second rotating shaft 12. One end of the rotary cantilever 2, which is far away from the mud beating unit 3, is provided with a pin hole 22 penetrating through the upper surface and the lower surface of the rotary cantilever, the end is also provided with a penetrating notch 23, a bolt 7 is arranged in the pin hole 22, and the bolt 7 is provided with a polished rod; a shaft hole 21 is formed in one end, close to the pin hole 22, of the rotary cantilever 2, the second rotating shaft 12 is located in the shaft hole 21, and a bearing is preferably arranged between the second rotating shaft 12 and the shaft hole 21; first pivot 11 rotates and is connected with pneumatic cylinder subassembly 6, the other end and the bolt 7 of pneumatic cylinder subassembly 6 rotate and are connected.

A thread part 121 is arranged above the second rotating shaft 12, a first nut 5 is connected to the thread part 121 in a threaded manner, and a gasket 4 is arranged between the first nut 5 and the rotary cantilever 2. This structure can prevent the swing arm 2 from falling off.

And one end of the bolt 7 is in threaded connection with a second nut 8, so that the bolt 7 is prevented from falling off.

The hydraulic cylinder assembly 6 comprises a cylinder body 61 and a piston rod 62, wherein a first rotating member 63 is arranged at the bottom of the cylinder body 61, a first through hole 631 penetrating through the upper surface and the lower surface of the first rotating member 63 is arranged on the first rotating member 63, a second rotating member 64 is arranged at the top end of the piston rod 62, and a second through hole 641 is arranged at the top end of the second rotating member 64; the first rotating shaft 11 is located in the first through hole 631, and the second rotating shaft 12 is located in the second through hole 641.

The working principle is as follows: as shown in fig. 1, the piston rod 62 is extended out to drive the rotary cantilever 2 to rotate clockwise, so that the mud pumping unit 3 approaches and blocks the taphole; retraction of the piston rod 62 drives the swing jib 2 to rotate anticlockwise so that the mud pumping unit 3 exits the tap hole. In order to prevent the hydraulic cylinder assembly 6 from overlapping with the connecting line between the first rotating shaft 11 and the second rotating shaft 12 (when the piston rod 62 is difficult to extend and the rotating direction of the rotating cantilever 2 cannot be controlled), the distance between the first rotating shaft 11 and the second rotating shaft 12 is slightly smaller than the sum of the length of the hydraulic cylinder assembly 6 and the distance between the bolt 7 and the second rotating shaft 12.

It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the utility model and are not to be construed as limiting the utility model. Therefore, any modifications, equivalents, improvements and the like which are made without departing from the spirit and scope of the present invention shall be included in the protection scope of the present invention.
