Description

Technical Field

[0001] The utility model belongs to the field of transmission machinery, in particular to a cantilever roller of a heating furnace which is easy to replace. Background Art

[0002] Because the cantilever roller head is located inside the furnace wall and is in constant contact with the high-temperature atmosphere inside the furnace wall, oxidation and burning often occur, so the cantilever roller head needs to be replaced regularly. Traditional heating furnace cantilever rollers are usually fixed to the cantilever roller mounting bracket set on the outside of the furnace wall via a bearing seat. Replacing the cantilever roller head requires lifting the cantilever roller out of the furnace wall as a whole using a crane or electric hoist before replacing the cantilever roller head. Due to the limitations of the lifting equipment and the availability of professional roller replacement personnel, rapid roller replacement is not possible. Utility Model Content

[0003] The purpose of the utility model is to provide a heating furnace cantilever roller which is easy to replace and has a simple and reasonable structure, is quick and convenient to replace, reduces labor intensity, and produces high-quality and efficient products.

[0004] The technical solution of the utility model is as follows: it includes a furnace wall, mounting holes, a cantilever roller, a roller head, a mounting bracket, a bearing seat, and a drive motor. The mounting bracket is a metal frame installed on both sides of the heating furnace wall, and two wheel tracks are installed on the metal frame. A traveling trolley is installed directly below the cantilever roller. Front and rear traveling wheels are installed below the frame on both sides of the traveling trolley. The traveling wheels are placed on the wheel tracks provided on the metal frame. The roller head is provided at the front end of the cantilever roller. It passes through the mounting hole provided in the furnace wall and is placed in the furnace. The end is mounted on the motor support frame provided on the frame via a bearing. It is connected to the motor provided on the motor support frame via a transmission device. The middle part is fixedly mounted on the grooved table of the traveling trolley via a bearing.

[0005] Its operating principle is:

[0006] A trolley is installed below the cantilever roller. The wheels at the four corners of the trolley are placed on tracks mounted on a metal frame. Positioning is achieved by the wheels and tracks, allowing the cantilever roller to enter and exit the furnace wall without the need for additional external equipment. When the cantilever roller head needs to be replaced, the entire cantilever roller can be moved in and out of the furnace wall simply by manually pushing the trolley.

[0007] The beneficial effects of the present utility model are as follows: a walking trolley is installed at the bottom of the cantilever roller, and the wheels of the walking trolley are installed on a walking track set on a metal frame, which not only provides a walking track for the walking wheel, but also realizes the positioning of the cantilever roller. When the cantilever roller head needs to be replaced, it is only necessary to manually pull the cantilever roller out of the furnace wall as a whole, replace the cantilever roller head, and then push the cantilever roller into the furnace wall as a whole after completion, so as to realize the rapid replacement of the cantilever roller head. This not only saves a lot of manpower and time for replacing the cantilever roller head, but also is not restricted by the lifting equipment. It has the advantages of simple and reasonable structure, convenient and simple replacement, reduced labor intensity, high-quality and efficient production, etc. Its promotion and application will bring good social and economic benefits to production enterprises, and its application value is very wide.

[0008] The present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 This is a schematic diagram of the assembly structure of the utility model.

[0010] In the figure: 1 is the wheel, 2 is the track, 3 is the metal frame, 4 is the cantilever roller, 5 is the furnace wall, 6 is the roller head, 7 is the mounting hole, 8 is the traveling trolley, 9 is the support frame, and 10 is the motor. DETAILED DESCRIPTION

[0011] like Figure 1As shown, a cantilever roller for a heating furnace that is easily replaceable includes a furnace wall 5, a mounting hole 7, a cantilever roller 4, a roller head 6, a mounting bracket, a bearing seat, and a drive motor 10. The mounting bracket is a metal frame 3 mounted on either side of the furnace wall 5, with two wheel tracks 2 provided on the metal frame 3. A trolley 8 is located directly below the cantilever roller 4. Front and rear wheels 1 are located below the frame on either side of the trolley 8, and the wheels 1 rest on the wheel tracks 2 provided on the metal frame 3. The cantilever roller 4 has a roller head 6 at its front end, which is placed into the furnace through a mounting hole 7 in the furnace wall 5. The roller is surrounded by refractory insulation cotton in the mounting hole 7. The end of the roller is mounted on a motor support frame 9 mounted on the frame via a bearing. The roller is connected to a motor 10 mounted on the motor support frame 9 via a transmission device. The middle portion is fixed to the grooved table of the trolley 8 via a bearing. During implementation of the present invention, the cantilever roller 4 is fixedly mounted on the trough-shaped tabletop of a trolley 8. Because the wheels 2 at the four corners of the bottom of the trolley 8 cooperate with the running tracks 1 on the cantilever roller mounting bracket made of a metal frame 3, the operator can conveniently push and pull the trolley 8 into or out of the furnace by simply manually pushing and pulling the trolley 8. When the roller head 6 at the front end of the cantilever roller 4 oxidizes or burns and needs to be replaced, the operator simply removes the insulation surrounding the mounting hole 7 on the furnace wall 5 and pulls the trolley 8 outward to quickly and easily pull the roller head 6 out of the mounting hole 7 on the furnace wall 5. The new roller head can then be quickly replaced, and the trolley 8 can be pushed along the running tracks 2 on the mounting bracket to push the cantilever roller head 6 from the mounting hole 7 on the furnace wall 5 into the furnace. This has the advantages of a simple and reasonable structure, quick and easy replacement, reduced labor intensity, and high-quality and efficient production, and has a broad market prospect.
