Problems solved by technology

[0004] Since the size of each link of the four-bar linkage mechanism is limited by space, and the four-bar linkage mechanism has multiple movable joints, there are many faults in the four-bar linkage mechanism during use, which increases the use and maintenance of the hydraulic mud gun. The cost and the labor intensity of workers have brought adverse effects on ironmaking production, so it is necessary to develop a hydraulic mud gun with reliable performance

Embodiment 1

[0026] see figure 1 , a hydraulic mud gun and its operating method, which includes a base 6 on which a boom 5 is rotatably supported by a first rotating shaft 7, and a rotary oil cylinder for driving its rotary action is installed between the boom 5 and the base 6 4. The end of the boom 5 is hung with a mud-beating mechanism 1 through the hanging mechanism 2, and a tie rod 3 for controlling the movement track of the mud-beating mechanism 1 is installed between the mud-beating mechanism 1 and the base 6. This hydraulic mud gun uses a hydraulic drive cylinder as the drive structure, replacing the traditional four-bar linkage mechanism. The rotary cylinder has a long stroke, which can satisfy the mud gun in a safe rest position when adding mud. During the working process, the mud beating mechanism 1 plays the role of mud beating, the hanging mechanism 2 connects the mud beating mechanism 1 and the big arm 5, and the pull rod 3 controls the movement track of the mud beating mechan...

Embodiment 2

[0031] The operation method of the hydraulic mud gun includes the following steps:

[0032] Step 1: When the hydraulic mud gun is in the rest position, put the gun mud into the mud cylinder of the mud making mechanism 1;

[0033] Step 2: The rotary cylinder 4 pushes the boom 5 to rotate to the working position, and drives the hanging mechanism 2 and the mud-beating mechanism 1 to rotate;

[0034] Step 3: The pull rod 3 controls the movement trajectory of the mud-beating mechanism 1 to ensure that the nozzle at the front end of the mud-beating mechanism 1 is aligned with the iron mouth when it is in the working position;

[0035] Step 4: The mud-beating mechanism 1 performs the mud-blocking operation;

[0036] Step 5: After the plugging operation is completed, the rotary cylinder 4 drives the relevant components to return to the rest position.

Abstract

The invention provides a hydraulic clay gun and an operation method, the hydraulic clay gun comprises a base, a big arm is rotatably supported on the base through a first rotating shaft, and a rotary oil cylinder used for driving the big arm to rotate is installed between the big arm and the base; a mud making mechanism is hung at the tail end of the large arm through a hanging mechanism, and a pull rod used for controlling the motion trail of the mud making mechanism is installed between the mud making mechanism and the base. According to the hydraulic clay gun, the hydraulic driving cylinder is adopted as a driving structure to replace a traditional four-bar mechanism, the stroke of the rotary oil cylinder is long, and the clay gun can be located at a safe rest position during clay adding.

Description

technical field [0001] The invention relates to the field of equipment in front of the furnace, in particular to a hydraulic mud gun and its operating method. Background technique [0002] During the ironmaking process of the blast furnace, the iron hole must be frequently blocked. The equipment used to block the iron hole is a hydraulic mud gun. The reliability of the hydraulic mud gun directly affects the production of the blast furnace, and it is one of the key equipment for the front production of the furnace. [0003] Existing hydraulic mud guns are converted between the working position and the rest position by driving the four-bar linkage with a shorter stroke of the rotary oil cylinder, and then the four-bar linkage pushes the boom to realize. [0004] Since the size of each link of the four-bar linkage mechanism is limited by space, and the four-bar linkage mechanism has multiple movable joints, there are many faults in the four-bar linkage mechanism during use, whi...
