The beneficial effect of the utility model is that through the moving assembly arranged at the bottom of the cantilever roller driving assembly, the driving assembly and the cantilever roller on the cantilever roller structure can be extracted when the cantilever roller structure fails or parts need to be replaced, thereby facilitating the staff to inspect and replace the components of the cantilever roller structure in non-high temperature areas, reducing safety hazards and greatly reducing the labor intensity of the staff.

[0004] The above patent discloses a cantilever roller structure for a step-type heating furnace, which solves the problem of potential safety hazards caused by workers inspecting and replacing the components of the cantilever roller structure in a non-high-temperature area. However, due to a certain gap when the moving component is pulled out of the roller table, insufficient sealing occurs, and dust and impurities enter the furnace, which not only affects the purity of the heating furnace, but also causes smoke to overflow from the furnace.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model proposes a cantilever roller for a step-type heating furnace. In the prior art, the sealing performance between the cantilever roller and the heating furnace is insufficient. However, the utility model uses a sealing block, a clamping block, a spring and a cylinder.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1 and Figure 2 A cantilever roller of a walking heating furnace includes a cantilever roller body 1, one end of the cantilever roller body 1 passes through the interior of a heating furnace 3, a roller table 2 is arranged inside the heating furnace 3, one end of the cantilever roller body 1 is located on the upper surface of the roller table 2, and a sealing component 4 for increasing the sealing performance is arranged on one side of the heating furnace 3.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4 The sealing assembly 4 includes a cylinder 41 arranged on the outer surface of the heating furnace 3, and a mounting ring 42 arranged on one side of the cylinder 41. A spring 43 is arranged on the inner wall of the cylinder 41, and a clamping block 44 is arranged at one end of the spring 43. A groove 45 is provided on the outer surface of the clamping block 44. A sealing block 46 is sleeved on the outer surface of the cantilever roller body 1. A connecting ring 47 is sleeved on the outer surface of the sealing block 46. The cantilever roller body 1 is movably connected to the inside of the sealing block 46. A threaded hole 48 is provided inside the mounting ring 42 and the connecting ring 47. The threaded holes 48 of the mounting ring 42 and the connecting ring 47 are provided. The internal thread of the groove 48 is connected with a bolt 49. When the cantilever roller body 1 is overhauled and returned to the roller table 2 in the heating furnace 3, the sealing block 46 is squeezed by moving the connecting ring 47, and the spring 43 is compressed. Since the outer surface of the clamping block 44 is provided with a groove 45, the clamping block 44 can clamp the cantilever roller body 1 while shrinking into the cylinder 41, and then the connecting ring 47 and the mounting ring 42 are connected together by the bolt 49, which can prevent the heat and smoke in the heating furnace 3 from escaping and prevent the external dust from entering the furnace.

[0026] The sealing block 46 is a member made of graphite, which has heat resistance and wear resistance, thereby extending the service life.

[0027] A sealing ring 5 is provided at the bottom of the sealing block 46. The sealing ring 5 is a component made of fluororubber. The fluororubber has high temperature resistance and elasticity, so the sealing effect can be further enhanced.

[0028] The inner wall of the clamp block 44 is provided with a wear-resistant layer 6, which is a component made of a nickel-based alloy containing chromium, molybdenum and tungsten elements. The wear-resistant layer 6 uses its high hardness and wear resistance to reduce wear caused by frequent friction.

[0029] The outer surface of the cylinder 41 is provided with a heat insulating layer 7 , which is a component made of ceramic fiber. The low thermal conductivity of the ceramic fiber is used to insulate high temperature and protect the sealing component 4 from high temperature.

[0030] A magnetic block 8 is provided on one side of the mounting ring 42, and a magnetic block 8 is also provided on one side of the connecting ring 47. The magnetic properties of the magnetic block 8 of the mounting ring 42 and the magnetic block 8 of the connecting ring 47 are opposite, and the two are magnetically connected, thereby achieving the purpose of rapid alignment of the mounting ring 42 and the connecting ring 47.

[0031] Specifically, after the cantilever roller body 1 is overhauled and returned to the roller table 2 in the heating furnace 3, the connecting ring 47 is moved. Since a magnetic block 8 is provided on one side of the mounting ring 42 and a magnetic block 8 is also provided on one side of the connecting ring 47, the magnetic blocks 8 of the mounting ring 42 and the magnetic blocks 8 of the connecting ring 47 are opposite in magnetism and are magnetically connected. Therefore, the mounting ring 42 and the connecting ring 47 can be quickly aligned, so that the sealing block 46 squeezes the clamping block 44. Since the sealing block 46 is a component made of graphite, the sealing block 46 has heat resistance and wear resistance, and its service life is extended. In addition, since a sealing ring 5 is provided at the bottom of the sealing block 46, and the sealing ring 5 is a component made of fluororubber, the sealing effect is further enhanced. The spring 43 is compressed at the same time. Since the outer surface of the clamp block 44 is provided with a groove 45, the clamp block 44 can clamp the cantilever roller body 1 while shrinking into the cylinder 41. Since the inner wall of the clamp block 44 is provided with a wear-resistant layer 6, the wear-resistant layer 6 is a component made of a nickel-based alloy containing chromium, molybdenum and tungsten elements, so it can also reduce the wear caused by friction. Then the connecting ring 47 and the mounting ring 42 are connected together by bolts 49, which can prevent the heat and smoke in the heating furnace 3 from overflowing, and prevent external dust from entering the furnace. In addition, since the outer surface of the cylinder 41 is provided with a heat insulation layer 7, the heat insulation layer 7 is a component made of ceramic fiber, so it can protect the sealing component 4 from high temperature and improve the safety of use.
