[0002] During blast furnace production, when the tuyere sleeve reaches a certain period of use or becomes damaged and leaks, it needs to be disassembled and replaced. Currently, most blast furnaces use sliding hammer devices to disassemble the medium and small sleeves. The sliding hammer devices weigh between 100kg and 150kg, are quite heavy and long, and generally require more than 4 people to carry them together. This not only increases the labor intensity of workers, but also makes it easy for safety accidents to occur during the handling process.

[0003] During the dismantling of the medium and small sleeves of a blast furnace, dismantling a single medium or small sleeve requires the sliding hammer device to be moved at least twice with the combined efforts of multiple people, which greatly consumes the physical strength of the workers.

[0019] See Figures 1-3 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a handle assembly 1 and a main frame 9. The handle assembly 1 is installed on one side of the main frame 9. A sliding hammer bracket 2 is provided on the main frame 9. A sliding hammer support 3 is provided on the top of the sliding hammer bracket 2. The main frame 9 has a T-shaped structure. A detachable wheel assembly 4 is provided at the front end of the main frame 9, and a universal caster 5 is provided at the end of the main frame 9. When disassembling the tuyeres sleeve, the height of the sliding hammer bracket needs to be adjusted by replacing the detachable wheel assembly according to the height of the blast furnace, so as to better cooperate with the blast furnace and smoothly transport the sliding hammer. Specifically, the base of the transport trolley is the main frame, and the sliding hammer bracket for support is provided on the main frame. When in use, the sliding hammer is lifted to the sliding position. On the hammer stand, the handle assembly can be used to push the trolley to transport the sliding hammer. When it is transported to the air vent or small sleeve to be replaced, the sliding hammer separates from the trolley. The trolley is then pushed away, and the sliding hammer can be used to remove the sleeve. After removing the sleeve, the sliding hammer can be placed back on the stand and transported to the next work station again. During transportation, the transport direction can be easily adjusted by the swivel casters. The swivel casters are also equipped with locking mechanisms, which can be fixed when stopped to prevent the trolley from moving at will. This not only improves convenience but also reduces the workload of the operators. In addition, the use of detachable wheel assemblies not only makes it easy to adjust the height according to actual needs, but also makes it easy to replace the wheel assemblies if they are damaged.

[0020] More specifically, the slide weight support 2 includes two support bodies 21 spaced apart. Each support body 21 is provided with a detachable slide weight support 3. In this embodiment, in order to better support the slide weight and ensure that the slide weight does not move, a slide weight support is provided on the support body. The slide weight support 3 has an arc-shaped structure with the arc opening facing upward, which can stably support the slide weight from the bottom. At the same time, since the support bodies are spaced apart, there is a protruding part in the middle of the slide weight. This part is placed between the two slide weight supports and is constrained by the two slide weight supports, so it will not move, thereby ensuring transportation safety.

[0021] More specifically, the handle assembly 1 includes a handle 11 and a handle base 12. The handle 11 has a hollow structure, and the handle base 12 is movably disposed inside the handle 11. Since the operator is not fixed for a long time, different operators have different heights and operating habits. When pushing the cart, specific adjustments need to be made according to individual circumstances. By setting a movable handle assembly, the fixed position of the handle can be easily adjusted, thereby adjusting its length, which is more in line with the operating habits of different operators.

[0022] More specifically, both the handle 11 and the handle base 12 are provided with several through-hole fixing pin holes 13, and a pin 6 is installed inside the fixing pin holes 13. A limiting hole is provided at the end of the pin 6, and a first cotter pin 7 is provided inside the limiting hole. In order to facilitate the adjustment of the specific length of the handle, fixing pin holes are provided on both the handle and the handle base. The pin can be positioned after adjustment by inserting it into the fixing pin hole. At the same time, a limiting hole is provided on the pin, and a first cotter pin is inserted into the limiting hole. The first cotter pin has its own tension, which can effectively fix the pin after it is inserted. When adjustment is needed, the first cotter pin can be pulled out to pull out the pin for adjustment, making adjustment more convenient.

[0023] More specifically, the detachable wheel assembly 4 includes a wheel axle 41, a solid wheel 42, a first wheel hub 43, and a second wheel hub 44. There are two first wheel hubs 43 symmetrically arranged on the wheel axle 41. There are also two solid wheels 42 and two second wheel hubs 44 symmetrically arranged. The second wheel hub 44 is disposed inside the solid wheel 42 and connected to the first wheel hub 43 by fastening screws 45. In this embodiment, a detachable wheel assembly is provided. When the height needs to be adjusted, only different sizes of practice wheels need to be used. Since the first wheel hub is installed on the wheel axle, it does not need to be replaced. However, since the first wheel hub is installed on the solid wheel, when disassembling, the fastening screws are unscrewed, and the solid wheel and the first wheel hub are replaced together. The required solid wheel is then installed and connected to the first wheel hub. Disassembly is convenient and replacement and maintenance are easier.

[0024] More specifically, the wheel axle 41 is provided with four wheel bearings 46, which are connected to the first wheel hub 43 and the second wheel hub 44. The wheel bearings ensure the smooth rotation of the wheel hub.

[0025] More specifically, the wheel axle 41 is also provided with two wheel axle nuts 47. The wheel axle nuts 47 are located on the outside of the second wheel hub 44, and a second cotter pin 48 is provided on them to connect with the wheel axle 41. In order to better fix and constrain the solid wheel, wheel axle nuts are provided on the wheel axle. The wheel axle nuts that cooperate with the second wheel hub also cooperate with the wheel bearing on it and are embedded in the wheel bearing, so as not to interfere with the rotation of the solid wheel. A through hole and a second cotter pin are also provided on it. The wheel axle nuts can be disassembled and installed by pulling and inserting the second cotter pin, so as to facilitate the replacement of the solid wheel.

[0026] The working principle of this utility model is as follows: In use, the specifications of the solid wheel 42 are selected according to the specific height of the tuyere platform in different types of blast furnace tuyeres (small and medium sizes) to obtain a matching trolley height and load-bearing capacity. When replacing the solid wheel 42, simply pull out the second cotter pin 48 to remove the wheel axle nut 47 and replace the solid wheel 42. Similarly, the universal caster 5 is also replaced with the same specification to ensure that the sliding hammer support 3 remains horizontal. Furthermore, due to differences in operator height and usage habits, the first... Pull out the pin 6 with the cotter pin 7, adjust the specific position of the handle, and then insert the pin 6 back in. This allows operators of different heights and usage habits to push the trolley for operation. Lift the air vent sleeve sliding hammer device and place it on the sliding hammer support 3, with the middle of the sliding hammer placed between the two sliding hammer supports 3. It is restrained by the two sliding hammer supports 3 to prevent it from loosening. After adjustment, push the trolley to transport the sliding hammer to the air vent sleeve that needs to be replaced. The sliding hammer separates from the sliding hammer support 3. Push the trolley away, and you can start using the sliding hammer to remove the sleeve.
