Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace probes, and in particular relates to a blast furnace probe with a safety protection structure. Background Art

[0002] The blast furnace probe is an important device for detecting the material level changes in the blast furnace during the iron-making production process. The blast furnace probe is usually set on the top of the blast furnace. The detection process of the blast furnace probe is divided into three processes: releasing the probe, floating the probe and retracting the probe.

[0003] The existing blast furnace probe uses a winch to wind up and release the wire rope, thereby adjusting the position of the probe block. During the winding or releasing of the wire rope, the probe block is easily disturbed by external factors and shakes, which is easy to collide with the inner wall of the blast furnace, causing damage to the inner wall of the blast furnace on the one hand, and damage to the probe block on the other hand, affecting its detection effect. Therefore, a blast furnace probe with a safety protection structure is urgently needed to solve the above problems. Summary of the invention

[0004] The utility model aims to provide a blast furnace probe with a safety protection structure, which can buffer and protect the impact formed by the probe block and the inner wall of the blast furnace, thereby ensuring the detection performance.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a blast furnace probe with a safety protection structure, including a base, supports are fixed on both sides of the upper end of the base, a winding drum is installed between the supports, a wire rope is wound on the winding drum, a motor is fixed on one side wall of the support, the motor is used to drive the winding drum to rotate, a probe block is fixed at one end of the wire rope, four groups of connecting cavities are distributed in a circle on the outer wall of the probe block, a damping rod is installed in the connecting cavity, a connecting column is arranged at one end of the damping rod, a spring is installed on the outer wall of the damping rod, the other end of the damping rod is fixedly connected to a buffer block, and a ball is installed at the outer end of the buffer block.

[0006] Furthermore, the connection cavity is formed on the probe block, the connection column is welded to the damping rod, the connection column is threadedly connected to the connection cavity, and the probe block is a frustum-shaped structure. The connection cavity and the connection column are combined to replace the damping rod of a suitable length according to the specifications of the blast furnace.

[0007] Furthermore, the damping rod is a telescopic structure, the spring is sleeved on the outside of the damping rod, the damping rod is fixedly connected to the buffer block, and the ball is rotatably connected to the buffer block. During the lifting process of the probe block, the damping rod and the spring are combined to buffer and protect the collision between the probe block and the inner wall of the blast furnace, while the buffer block and the ball are combined to reduce the friction between the two, ensuring the lifting performance, and then the probe block and the inner wall of the blast furnace can be protected at the same time to ensure the detection performance.

[0008] Furthermore, the support is welded to both sides of the upper end of the base, and the winding drum is rotatably connected to the support, and the winding drum provides a winding position for the wire rope.

[0009] Furthermore, the motor is connected to the support by bolts, the output shaft of the motor is fixedly connected to the winding drum, and the motor is a reduction motor. The motor winds or releases the wire rope through the winding drum, thereby changing the position of the probe block in the blast furnace.

[0010] Furthermore, an electric slide rail is installed inside one side wall of the base, and a slider is slidably connected inside the electric slide rail.

[0011] Furthermore, a guide block is fixedly connected to one side wall of the slider, and a guide cavity is provided on the guide block for the steel wire rope to pass through. The slider drives the guide block to move left and right in the electric slide rail, so that the steel wire rope can be flatly wound on the winding drum. The guide block and the guide cavity can guide the movement of the steel wire rope.

[0012] The utility model has the following beneficial effects:

[0013] The utility model arranges a damping rod, a spring, a buffer block and a ball. During the lifting process of the probe block, the damping rod and the spring are combined to buffer and protect the collision between the probe block and the inner wall of the blast furnace. At the same time, the ball arranged at the outer end of the buffer block converts sliding friction into rolling friction, reduces the friction between the buffer block and the inner wall of the blast furnace, ensures its lifting performance, and further can protect the probe block and the inner wall of the blast furnace at the same time, ensuring the detection performance.
