Description

Technical Field

[0001] This utility model relates to a tool used in the converter steelmaking process, and in particular to a device for safely and conveniently installing a converter slag-blocking cap. Background Technology

[0002] The converter slag cap is shaped like a conical frustum 1 (see appendix). Figure 1 The slag-blocking cap has a circular hole 2 on its bottom surface for inserting a steel rod or stake during installation. Currently, there are two main methods for installing slag-blocking caps in converter steelmaking: manual operation and mechanical operation. Manual operation involves workers using a steel rod to insert into the circular hole on the bottom surface of the slag-blocking cap, lifting it, and then placing it into the taphole from the furnace outlet. Mechanical operation involves laying a track in front of the converter opening, with an installation vehicle equipped with a stake running on the track. Both of these existing slag-blocking cap installation techniques have their shortcomings in practice. The shortcomings of manually installing converter slag-blocking caps are as follows: 1. Poor safety: The steel rods held by workers are relatively short. During the process of inserting the rod into the slag-blocking cap and placing it into the taphole, the worker is very close to the taphole. The splashing molten steel and the high temperature of the furnace mouth pose a great danger to the worker's life and health, which obviously does not meet the requirements of modern industry for worker safety protection; 2. High labor intensity: The slag-blocking cap is quite heavy, generally between 10 and 20 kilograms. Using a long steel rod to lift the slag-blocking cap generates a large torque force on the worker's hand, which is very strenuous and causes fatigue; 3. Poor operational accuracy: Due to the high temperature of the furnace mouth, the time for workers to insert the slag-blocking cap into the taphole with the steel rod is very short, making it difficult to adjust the accuracy of the slag-blocking cap's placement, thus affecting the slag-blocking effect of the cap. II. The shortcomings of the installation vehicle are: 1. High purchase cost, generally around 200,000 yuan per unit; 2. Complex structure of the device, prone to failure, especially since the device contains many sensors for detecting parameters such as position, angle, and pressure, as well as various expansion joints. These components are easily damaged in high-temperature and dusty environments, which can affect the operation of the device or make it difficult to install the slag-blocking cap accurately and affect the slag-blocking effect; 3. Difficult maintenance: Due to the complex structure of the device and the harsh working environment, maintenance is difficult and costly. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing converter ash baffle cap installation technology by proposing a safe and convenient device for installing converter ash baffle caps. It has the advantages of low investment, virtually no failures, minimal maintenance and repair work, good safety, ease of use, and accurate installation.

[0004] The purpose of this utility model can be achieved through the following technical solution: a device for safely and conveniently installing a converter slag-blocking cap, characterized in that it comprises three parts: a load-bearing movable component, a support frame, and a working rod; the load-bearing movable component consists of a shaft, bearings, and wheels, with the wheels rotatably fixed to both ends of the shaft via bearings; the support frame is formed by connecting a main support rod and an auxiliary support rod; the working rod consists of an insert rod, a baffle, a rod body, a hook, a counterweight, and an operating handle; the baffle is fixed to one end of the rod body, the insert rod is fixed to the baffle, and the other end of the rod body is the operating handle; a hook is provided on the rod body between the center point of the rod body and the operating handle, and the hook corresponds to the counterweight attached thereto; the working rod is fixed to the load-bearing movable component via the support frame.

[0005] For ease of production, transportation, and assembly, the rod is divided into three sections, which are connected by connectors.

[0006] To facilitate easy removal of the insert rod from the slag-blocking cap, the length of the insert rod is less than the depth of the hole in the slag-blocking cap.

[0007] To facilitate the insertion of the slag-blocking cap, the center of gravity of the working rod is biased towards the insertion end of the working rod when it is empty.

[0008] Beneficial effects:

[0009] 1. High safety: The operating rod in this device is long enough to allow operators to install the slag-blocking cap from a distance away from the steel taphole, avoiding harm to workers from high temperatures and molten steel, thus ensuring their safety and health. 2. Low production cost: Firstly, the device costs less than a thousand yuan, a fraction of the price of existing devices. Secondly, its simple structure ensures virtually no malfunctions and requires no maintenance or repair costs, resulting in extremely low operating costs and significantly improving the company's economic efficiency. 3. Simple, convenient, quick, and labor-saving operation: The device mainly consists of an operating rod and two wheels that work together, making it very easy to operate. After inserting the rod into the slag-blocking cap, a counterweight is attached to the hook, and the rod can be easily operated for installation. 4. Stable and reliable operation: Sufficient time is available to adjust the accuracy of the slag-blocking cap's placement, ensuring accurate installation and guaranteeing the slag-blocking effect.

[0013] Appendix Figure 3This is a top view of the structure of this utility model. Detailed Implementation

[0014] Note that the embodiments listed below are merely examples of this technical solution. Other embodiments with the same function as this technical solution obtained by those skilled in the art without creative effort are all within the scope of protection of this technical solution.

[0015] See appendix Figure 2 , 3 This invention relates to a safe and convenient device for installing a converter slag cap. It mainly consists of three components: a working rod, a load-bearing movable component, and a support frame. The working rod comprises an insert rod 1, a baffle 2, a rod body 3, a hook 4, a counterweight 5, and an operating handle 6. The baffle 2 is fixed to one end of the rod body 3, the insert rod 1 is fixed to the baffle 2, and the operating handle 6 is located at the other end of the rod body 3. A hook 4 is provided on the rod body between the center point of the rod body 3 and the operating handle 6, corresponding to the counterweight 5 attached to it. The load-bearing movable component consists of a shaft 7, bearings (not shown in the figure), and wheels 8. The wheels 6 are rotatably fixed to both ends of the shaft 7 via bearings. The support frame consists of a main support rod 9 and an auxiliary support rod 10. The ends of the main support rod 9 and the auxiliary support rod 10 are respectively fixed to the shaft 7 and the rod body 3, connecting the working rod and the load-bearing movable component into a whole. For ease of production, transportation, and assembly, the rod body 3 can be divided into three sections, which can be connected by flanges or other connecting parts. To facilitate easy removal of the insert rod 1 from the slag-blocking cap, the length of the insert rod 1 is less than the depth of the hole in the slag-blocking cap, and the diameter of the insert rod 1 is less than the inner diameter of the hole in the slag-blocking cap. This dimensional fit ensures that the slag-blocking cap fitted on the insert rod will not be damaged, and also ensures that after the slag-blocking cap is reliably pushed into and out of the steel outlet by the baffle 2, the insert rod can be smoothly removed from the slag-blocking cap. To facilitate operation when inserting the slag-blocking cap, the center of gravity of the working rod when empty is biased towards the insert end of the working rod, so that this end is in a downward state when empty, making it easy for the operator to insert the slag-blocking cap. After inserting the slag-blocking cap, the weight of the attached counterweight should ensure that the center of gravity of the working rod is at the support point of the main support rod 9, and the two ends of the working rod are basically balanced, so that the operator can easily push the working rod and the load-bearing moving parts to move and operate.

[0016] The operating procedure of this device is as follows: When the operating rod is empty, the insertion end of the rod is in the lowered state. The operator holds the operating handle 6 and applies slight downward force to lift the insertion end of the rod, making the operating rod horizontal and balanced. At this point, the device can be pushed to the slag-blocking cap, and the slag-blocking cap is inserted using the insertion rod. After inserting the slag-blocking cap, the operator hangs the counterweight on the hook, so that the center of gravity of the operating rod is at the support point of the main support rod 9. The two ends of the operating rod are basically balanced, and the operator can easily push the device to move and operate. After the slag-blocking cap is accurately installed, the counterweight is removed and the device is withdrawn.
