Description

Technical Field

[0001] This utility model relates to the field of converter lining construction technology, and in particular to an auxiliary device for converter lining construction. Background Technology

[0002] A converter is a common smelting equipment used to produce carbon steel, alloy steel, copper, and nickel. The converter lining is a layer of refractory material built inside the converter's metal shell, mainly used to complete the steelmaking reaction and provide a high-temperature and corrosion-resistant container structure. Because the converter lining has a certain service life, maintenance and repair work is required to ensure its normal operation.

The lifting beam is fixed on the converter opening, and the folding platform is suspended inside the converter by the hand-operated hoist. The transfer platform is fixed on the steel tapping platform at the rear of the converter, the upper end of the inclined slide is set on the converter tapping opening, and the lower end of the inclined slide is set on the folding platform."

[0004] This existing patent employs a flexible hoisting structure to facilitate the lifting and lowering of the work platform (folding platform). It also incorporates slides on the platform to facilitate material transport, allowing materials such as blocks to slide onto it. However, because the materials falling onto the platform cause impact, even with cushioning rubber tires at the end of the slides, the platform is still subjected to force. Heavy falling materials can cause the platform to shake, disrupting normal work operations, potentially scattering items, and even posing a safety hazard. Utility Model Content

Converter. Detailed Implementation

[0039] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] like Figure 1 and Figure 2 As shown, this embodiment discloses an auxiliary device for converter lining construction, including a detachable construction platform 1. The lower end of the construction platform 1 is provided with an adjustable support leg 2, and the end of the support leg 2 is tightly pressed against the inner wall of the converter 8. The upper end of the construction platform 1 is connected to one end of a lifting and suspension mechanism 3, and the other end of the lifting and suspension mechanism 3 is set on the furnace mouth of the converter 8 through a frame.

[0041] A slide rail 4 is installed on the construction platform 1. One end of the slide rail 4 is located inside the steel tapping port 5, and the other end of the slide rail 4 abuts against a buffer mechanism 6. The buffer mechanism 6 is slidably mounted on a buffer seat 7, which is located on the construction platform 1. The buffer mechanism 6 includes a buffer section 6-1, one end of which abuts against the inner wall of the converter 8, and the other end of which is connected to a sliding section 6-2, which is slidably mounted on the buffer seat 7. When materials are transported using the slide rail 4, the materials slide down the slide rail 4 and land on the buffer mechanism 6. Simultaneously, due to inertia, the materials push and impact the buffer section 6-1, which provides force relief and buffering, preventing direct impact from the materials on the construction platform 1. It should be noted that a frame can be erected on the construction platform 1 to support the slide rail 4 to ensure its stability.

[0042] In this embodiment, the lifting and suspension mechanism 3 is a hand-operated hoist. Multiple hand-operated hoists are provided, and multiple fixed hooks are installed on the main body 1-1 of the construction platform 1 for connecting to the hand-operated hoists, thereby realizing the lifting and adjustment of the construction platform 1. The hand-operated hoist is an existing technology and will not be described in detail here.

[0043] like Figures 3 to 5 As shown, the construction platform 1 includes a main platform 1-1, support legs 2, and buffer seats 7, all of which are detachably connected to the main platform 1-1 via bolt assemblies. The upper end of the main platform 1-1 is connected to one end of the lifting and suspension mechanism 3. The size of the main platform 1-1 is smaller than the furnace opening of the converter 8 to facilitate placement into the furnace. The main platform 1-1 is provided with an installation groove 1-2, in which a steel frame 1-4 is inserted. The length of the steel frame 1-4 is longer than that of the main platform 1-1. Then, a fan-shaped plate 1-3 is laid on the steel frame 1-4, thereby expanding the working area of ​​the construction platform 1. To increase the stability of the construction platform 1, threaded holes are reserved on the fan-shaped plate 1-3 and the steel frame 1-4, which can be fastened together using bolt assemblies.

[0044] like Figure 6 and Figure 7 As shown, the buffer seat 7 includes a support frame 7-1, which is detachably connected to the main body 1-1 via bolt assemblies. A slide rail seat 7-2 is provided at the upper end of the support frame 7-1, and a sliding part 6-2 is slidably disposed within the slide rail seat 7-2. The slide rail seat 7-2 is arranged at an angle so that when material slides down and contacts the buffer mechanism 6, it continues to slide a certain distance, thereby reducing the impact on the support frame 7-1 in the vertical direction.

[0045] In this embodiment, a fixedly connected guard plate 6-3 is provided on the sliding part 6-2. The bottom of the side of the guard plate 6-3 facing away from the buffer part 6-1 abuts against the slide rail 4. When the material slides to the end of the slide rail 4, due to the inclined arrangement of the slide rail seat 7-2, it can fall into the guard plate 6-3. The guard plate 6-3 plays a protective role and can prevent the material from falling onto the construction platform 1.

[0046] The buffer part 6-1 is a spring, one end of which is connected to the sliding part 6-2, and the other end of which rests against the inner wall of the converter 8. After the material falls into the guard plate 6-3, the sliding part 6-2 compresses the spring while sliding along the slide rail seat 7-2 until it stops. In this way, the impact of the material falling is buffered by the elastic force of the spring and the support of the inner wall of the converter 8, which greatly reduces the impact on the construction platform 1.

[0047] like Figure 8 and Figure 9 As shown, in this embodiment, a guide limiting groove 7-2-1 is provided in the side wall of the slide rail seat 7-2, a dovetail groove 7-2-2 is provided on the bottom inner wall of the slide rail seat 7-2, guide limiting slide rails 6-2-1 are provided on both side walls of the sliding part 6-2, and a dovetail slide rail 6-2-2 is provided at the bottom of the sliding part 6-2. The guide limiting slide rail 6-2-1 is slidably disposed in the guide limiting groove 7-2-1, and the dovetail slide rail 6-2-2 is slidably disposed in the dovetail groove 7-2-2, thereby guiding the sliding of the sliding part 6-2.

[0048] like Figure 10 and Figure 11 As shown, the support leg 2 includes a support tube 2-1, which is detachably connected to the main body platform 1-1 by a bolt assembly. A fixing tube 2-2 is provided on the support tube 2-1, and a slidingly connected support tube 2-3 is provided inside the fixing tube 2-2. The end of the support tube 2-3 is tightly pressed against the inner wall of the converter 8.

[0049] A slidingly connected push block 2-4 is provided inside the fixed tube 2-2. One end of the push block 2-4 is connected to one end of a connecting spring 2-5, and the other end of the connecting spring 2-5 is connected to the inner wall of the support tube 2-3. A handle 2-6 is fixedly provided on the push block 2-4, and the handle 2-6 is slidably disposed in a slot 2-7, which is located on the side wall of the fixed tube 2-2. Several first positioning holes 2-2-1 are provided on the side wall of the fixed tube 2-2, and several second positioning holes 2-3-1 are provided on the side wall of the support tube 2-3. The first positioning holes 2-2-1 and the second positioning holes 2-3-1 are connected by a pin 2-8.

[0050] In this embodiment, there are two handles 2-6 and two slots 2-7, which are respectively located on both sides of the fixing tube 2-2.

[0051] In this embodiment, a guide slider 2-2-2 is provided on the inner wall of the end where the fixed tube 2-2 connects to the support tube 2-3, and a guide groove 2-3-2 is provided on the side wall of the support tube 2-3. The guide slider 2-2-2 and the guide groove 2-3-2 are slidably connected. In this way, the sliding guidance function of the support tube 2-3 is realized.

[0052] In this embodiment, four support legs 2 are provided, evenly distributed at the four corners of the main platform 1-1. During installation, the support tube 2-1 is first installed on the main platform 1-1 using bolt assemblies. The pin 2-8 is then removed, allowing the support tube 2-3 to slide relative to the fixed tube 2-2. With the main platform 1-1 stable, one support leg 2 is adjusted by pushing the handle 2-6, which pushes the connecting spring 2-5 and the support tube 2-3, pressing the support tube 2-3 against the inner wall of the converter 8. The pin 2-8 is then inserted into the first positioning hole 2-2-1 and the second positioning hole 2-3-1 of the support leg 2, fixing the support tube 2-3 relative to the fixed tube 2-2. The same operation is performed for the adjacent support leg 2. When adjusting the third support leg, the handle 2-6 is pushed forcefully to press the support tube 2-3 tightly against the inner wall of the converter 8 until the handle 2-6 can no longer be pushed. Then, the pin 2-8 is used to fix the support tube 2-3 to the fixed tube 2-2. The operation of the fourth support leg 2 is the same as that of the third support leg 2. Thus, the construction platform 1 is stably supported by the four support legs 2.

[0053] like Figures 1 to 11 As shown, the working process of this utility model is as follows:

[0054] First, a frame is erected on the furnace mouth of converter 8, and a lifting and suspension mechanism 3, i.e., a hand-operated hoist, is installed. The main platform 1-1 is lowered into converter 8 using the hand-operated hoist, and the fan-shaped plate 1-3 is erected. The support legs 2 are adjusted, and the slide 4 is set up. The material is put into the tap hole 5, and the material slides down the slide 4 into the guard plate 6-3. The sliding part 6-2 slides along the slide rail seat 7-2 while compressing the buffer part 6-1. In this way, the material falls smoothly without impacting the construction platform 1.

[0055] When the height of the construction platform 1 needs to be adjusted, pull out the pin 2-8 of the support leg 2, retract the support tube 2-3 into the fixing tube 2-2, and then insert the pin 2-8 to fix it. Use the lifting suspension mechanism 3, i.e., the hand-operated hoist, to raise the construction platform 1 a certain distance. After the construction platform 1 is stable, readjust the support leg 2 so that the support tube 2-3 is against the inner wall of the converter 8. After the adjustment is completed, the construction work can continue.

[0056] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
