Description

Technical Field

[0001] This utility model relates to the field of blast furnace equipment technology, and in particular to a front component of a hydraulic tapping machine. Background Technology

[0002] In the process of blast furnace ironmaking, taphole opening operations must be performed frequently. The core equipment for taphole opening is the hydraulic taphole opener. During operation, the hydraulic taphole opener undergoes rotation and high-frequency impact. Some parts of the hydraulic taphole opener, especially the parts in the front assembly, are wear parts and need to be replaced frequently.

[0003] A typical hydraulic opening machine generally consists of three main parts: the impact section, the rotating section, and the front assembly. (See also...) Figure 1 The front assembly consists of a housing 100 containing all or some of the following components: a vibrating rod, a buffer sleeve, a limiting ring, an impact sleeve, a water sleeve, a support sleeve, an impact pad, and seals. Tightening the locking nut 200 connects the front assembly as a single unit. Replacing vulnerable parts within the front assembly requires first loosening and removing the locking nut 200, then pulling out all or some of the internal components. This operation is relatively complex, and disassembly is difficult if a part becomes stuck. Furthermore, the locking nut 200 is prone to loosening during the opening machine's operation, requiring frequent manual tightening, which increases labor intensity. Utility Model Content

[0004] This invention addresses the technical problem of the difficulty in disassembling and replacing easily damaged parts in the front assembly of a hydraulic opening machine, by providing a front assembly for such a machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A front assembly of a hydraulic opening machine includes: a front housing, a rear housing, a vibrating rod, a buffer sleeve, a limiting ring, an impact pad, a water jacket assembly, a support sleeve, and a buffer pad; The front housing has a first chamber, which is connected at both ends. The first chamber has a buffer pad, a water jacket assembly, and an impact pad arranged sequentially from the distal end to the proximal end. The support sleeve is located inside the water jacket assembly, and the distal end of the water jacket assembly is located inside the buffer pad. The vibrating rod passes through the impact pad, the support sleeve, and the water jacket assembly. The rear housing is provided with a second chamber, which is connected at both ends; the second chamber is provided with the buffer sleeve and the limiting ring in sequence from the distal end to the proximal end, and the vibrating rod passes through the buffer sleeve and the limiting ring; The proximal end of the rear housing is detachably fixedly connected to the proximal end of the front housing.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the proximal ends of the front housing and the rear housing are respectively provided with first connecting holes, and the first connecting holes on the front housing and the first connecting holes on the rear housing are provided in a one-to-one correspondence. The first connector passes through the first connecting hole to fix the front housing and the rear housing together.

[0008] Furthermore, a plurality of the first connection holes are symmetrically distributed at the proximal end of the front housing and the proximal end of the rear housing.

[0009] Furthermore, a second connecting hole is provided at the proximal end of the front housing and the proximal end of the rear housing, and the second connecting holes on the front housing and the second connecting holes on the rear housing are provided in a one-to-one correspondence. The second connector passes through the second connecting hole to fix the front housing to the rear housing.

[0010] Furthermore, a plurality of the second connecting holes are symmetrically distributed at the proximal end of the front housing and the proximal end of the rear housing; The diameter of the second connecting hole is smaller than the diameter of the first connecting hole.

[0011] Furthermore, the proximal end of the rear housing and the proximal end of the front housing are configured to engage in a mating structure.

[0012] Compared with the prior art, the hydraulic opening machine front assembly provided by this utility model has the following beneficial effects: The hydraulic opening machine front assembly provided by this utility model has a first chamber inside the front housing, with its proximal and distal ends connected. From the distal end to the inner end of the first chamber, a buffer pad, a water jacket assembly, and an impact pad are sequentially arranged. A support sleeve is located inside the water jacket assembly, with the distal end of the water jacket assembly located inside the buffer pad. A vibrating rod passes through the impact pad, the support sleeve, and the water jacket assembly. A second chamber is inside the rear housing, with its proximal and distal ends connected. From the distal end to the inner end of the second chamber, a buffer sleeve and a limiting ring are sequentially arranged. The vibrating rod passes through the buffer sleeve and the limiting ring. The proximal end of the rear housing is detachably fixedly connected to the proximal end of the front housing. The front assembly of this hydraulic decanter employs a structure where the front and rear housings are connected. Some vulnerable parts are located in the first chamber of the front housing, and others in the second chamber of the rear housing. When vulnerable parts need replacement, simply separate the front and rear housings, locate the corresponding vulnerable part, and disassemble and replace it. This eliminates the need to disassemble and replace all vulnerable parts, reducing the difficulty and efficiency of disassembling and replacing the front assembly. Furthermore, the device eliminates the need for locking nuts, ensuring that components within the front assembly do not loosen during operation. Attached Figure Description

A support sleeve 8 is located inside the water jacket assembly 7, and the distal end of the water jacket assembly 7 is located inside the buffer pad 9. A vibrating rod 3 passes through the impact pad 6, the support sleeve 8, and the water jacket assembly 7. A second chamber is provided inside the rear housing 1, with its proximal and distal ends connected. The second chamber extends from the distal end (defined...) Figure 2 The left side of the middle and rear shell 1 is the distal end of the second chamber (defined). Figure 2 A buffer sleeve 4 and a limiting ring 5 are sequentially arranged on the right side of the rear housing 1 (the proximal end of the second chamber), and the vibrating rod 3 passes through the buffer sleeve 4 and the limiting ring 5. The proximal end of the rear housing 1 is detachably fixedly connected to the proximal end of the front housing 2.

[0021] In a preferred embodiment provided by this utility model, see [link to previous section]. Figure 2 and Figure 3 The front housing 2 and the rear housing 1 each have a first connecting hole at their proximal ends, and the first connecting holes on the front housing 2 and the rear housing 1 are arranged in a one-to-one correspondence. The first connecting member 11 passes through the first connecting hole to fix the front housing 2 and the rear housing 1 together. Multiple first connecting holes are symmetrically distributed at the proximal ends of the front housing 2 and the rear housing 1.

[0022] A second connecting hole is provided at the proximal end of the front housing 2 and the proximal end of the rear housing 1, respectively, with the second connecting holes on the front housing 2 and the rear housing 1 arranged in a one-to-one correspondence. A second connecting member 10 passes through the second connecting hole to fix the front housing 2 and the rear housing 1 together. Multiple second connecting holes are symmetrically distributed at the proximal ends of the front housing 2 and the rear housing 1. The diameter of the second connecting member 10 is smaller than the diameter of the first connecting member 11. By using first connecting members 11 and second connecting members 10 with different diameters, reliable fixation of the front housing 2 and the rear housing 1 can be achieved.

[0023] In a preferred embodiment of this utility model, the proximal end of the rear housing 1 and the proximal end of the front housing 2 are configured as a mating interlocking structure; specifically, the interlocking structure is configured as a 90-degree right angle shape, and the interlocking structure facilitates the alignment of the front housing 2 and the rear housing 1 during assembly.

[0024] See Figure 2 and Figure 3 The hydraulic opening machine front assembly provided in this embodiment of the present invention has the following beneficial effects: The front assembly of the hydraulic opening machine provided in this embodiment of the utility model has a first chamber in the front housing 2, with its proximal and distal ends connected. From the distal end to the inner end of the first chamber, a buffer pad 9, a water jacket assembly 7, and an impact pad 6 are sequentially arranged. A support sleeve 8 is located inside the water jacket assembly 7, with the distal end of the water jacket assembly 7 located inside the buffer pad 9. A vibrating rod 3 passes through the impact pad 6, the support sleeve 8, and the water jacket assembly 7. A second chamber is provided in the rear housing 1, with its proximal and distal ends connected. From the distal end to the inner end of the second chamber, a buffer sleeve 4 and a limiting ring 5 are sequentially arranged. The vibrating rod 3 passes through the buffer sleeve 4 and the limiting ring 5. The proximal end of the rear housing 1 is detachably fixedly connected to the proximal end of the front housing 2. The front assembly of this hydraulic decanting machine adopts a structure in which the front housing 2 and the rear housing 1 are connected. Some vulnerable parts are located in the first chamber of the front housing 2, and the other vulnerable parts are located in the second chamber of the rear housing 1. When vulnerable parts need to be replaced, it is only necessary to separate the front housing 2 and the rear housing 1 into two parts, locate the corresponding vulnerable part, and disassemble and replace it, without having to disassemble and replace all vulnerable parts. This reduces the difficulty of disassembling and replacing the front assembly of the hydraulic decanting machine and improves the efficiency of disassembly and replacement. The device also eliminates the need for a locking nut, ensuring that the components inside the front assembly will not loosen during the operation of the decanting machine.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
