Abstract
Description
Technical Field
[0001] This utility model relates to the fields of iron and steel smelting and coal chemical technology, and more specifically, to a monitoring device for the counterweight block during the operation of a Wiggins-type gas holder. Background Technology
[0002] The Wiggins-type gas holder mainly consists of a base plate, side plates, a top plate, a piston, sleeve-type guardrails, a specially designed sealing curtain to maintain airtightness, and counterweights and balancing devices. In metallurgical enterprises, it is commonly used to store converter gas. During operation, the gas is fed in and out by the movement of the piston.
[0003] The piston is balanced by several counterweights on top of the gas holder. If the bearings or guide wheels of the counterweights are damaged, they may derail and scrape against the annular windproof steel frame on the outside of the gas holder. In severe cases, this may cause the counterweights to fall off, the wire rope to derail or break, the piston plate to overturn or even fall off, or the rubber inner diaphragm to tear or be damaged, which can easily lead to major safety accidents such as gas leaks, fires, explosions, and personnel poisoning. Utility Model Content
[0004] To address the aforementioned technical problems, this invention provides a monitoring device for the counterweight of a Wiggins-type gas holder during operation. This device monitors the operating status of the piston and counterweight of a Wiggins-type converter gas holder, enabling timely information transmission and alarm signals to the control room in case of abnormalities. This helps prevent gas holder malfunctions and even safety accidents, allowing gas holder operators to accurately monitor the position and status of the piston in real time, thus providing a reliable guarantee for the safe operation of the gas holder.
[0005] The technical means adopted in this utility model are as follows:
[0006] A monitoring device for the counterweight of a Wiggins-type gas holder during operation includes: a first laser ranging displacement sensor, a second laser ranging displacement sensor, and a camera, wherein:

[0009] The camera is positioned below the first laser ranging displacement sensor and the second laser ranging displacement sensor to collect the status of the first laser ranging displacement sensor, the second laser ranging displacement sensor, the counterweight guide wheel, and the counterweight slide.
[0010] The main control equipment determines whether there is a drift deviation value in the counterweight based on the real-time signals detected by the first laser ranging displacement sensor and the second laser ranging displacement sensor. If there is a drift deviation value, it indicates that there is a risk of derailment of the counterweight and an audible and visual alarm is issued. At the same time, the main control equipment retrieves the image captured by the camera to accurately determine the fault location and status that triggered the audible and visual alarm.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0030] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0031] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
