Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode column detection, in particular to a device for detecting the perpendicularity of the end face of a graphite electrode column. Background Technique

[0002] Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are made through calcination, batching, kneading, molding, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of electric arcs in arc furnaces to heat and melt furnace charges. According to their quality index levels, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes mainly include four categories: ordinary power graphite electrodes, antioxidant coating graphite electrodes, high power graphite electrodes, and ultra-high power graphite electrodes.

[0003] After the production of graphite electrode columns, the perpendicularity needs to be detected. Traditional detection devices, such as the utility model patent with the publication number CN215572844U, all perform single-end face detection. Generally, a graphite electrode has two end faces. After the single-end face detection is completed, the detection of the other end face is required, resulting in a significantly lower overall detection efficiency. Therefore, how to solve this problem is what we need to consider. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a device for detecting the perpendicularity of the end face of a graphite electrode column. During the use of this detection device, synchronous detection of the two end faces of the graphite electrode can be carried out, effectively improving the detection efficiency compared with the existing single-face detection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A device for detecting the perpendicularity of the end face of a graphite electrode column includes a base, and an L-shaped support frame is fixedly connected to the upper end of the base. The L-shaped support frame is composed of a vertical plate and a horizontal plate; a detection mechanism, the detection mechanism includes two first hydraulic expansion rods symmetrically installed at the lower end of the horizontal plate. The expansion ends of the two first hydraulic expansion rods are fixedly connected with mounting bars, and a second hydraulic expansion rod is fixedly connected to the opposite sides of the two mounting bars. The expansion ends of the two second hydraulic expansion rods are jointly installed with a perpendicularity detector; a limiting mechanism, and the limiting mechanism is used to limit the electrode column.

[0007] Preferably, the limiting mechanism includes a vertical plate fixedly connected to the base, and a rotating cylinder is horizontally penetrated through the vertical plate. The rotating cylinder is rotationally connected to the vertical plate through a bearing.

[0008] Preferably, two lower clamping plates are symmetrically and fixedly connected to the inner bottom of the rotating cylinder. Two upper clamping plates are symmetrically arranged inside the rotating cylinder. A twisting screw is rotatably connected to each upper clamping plate. The upper end of each twisting screw penetrates through the inner wall of the corresponding rotating cylinder and is threadedly connected to the inner wall of the rotating cylinder.

[0009] Preferably, a plurality of guiding telescopic rods are installed at the inner top of the rotating cylinder. The telescopic end of each guiding telescopic rod is fixedly connected to the corresponding upper clamping plate.

[0010] Preferably, both the upper clamping plate and the lower clamping plate are arc-shaped plates.

[0011] Preferably, a motor is installed on the left side of the vertical plate. Pulley wheels are installed on the output shaft of the motor and on the rotating cylinder. The two pulley wheels are connected by a transmission belt.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] A rotating cylinder is provided. By means of central limiting, both end faces are exposed, so that in cooperation with the use of a perpendicularity detector, synchronous detection of both end faces of the electrode rod can be realized, and the perpendicularity of two end faces can be detected at one time. Compared with the prior art, the detection efficiency is effectively improved. In addition, the limiting part is composed of two groups of symmetrical limiting structures, making the overall limiting more stable and ensuring the stability during detection.
