Description

Technical Field

[0001] This invention relates to the field of ring feeder accessories, and more particularly to a ring feeder traveling wheel that reduces the failure rate. Background Technology

[0002] As a core piece of equipment for conveying bulk materials such as coal and ore, the ring feeder is widely used in industries such as thermal power, metallurgy, and mining. Its traveling wheels are key components that ensure the equipment moves smoothly along the track and achieves continuous feeding. In actual operation, factors such as the impact of coal during the feeding process, uneven track, and the weight of the equipment itself will generate continuous vibration forces, which directly act on the traveling wheels and related connecting structures.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] First Embodiment

Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The diagram shows the structure of the vibration damping component.

[0033] A ring-shaped coal feeder traveling wheel with reduced failure rate includes: mounting assembly 2;

[0034] A buffer assembly 3 is disposed at the bottom of the mounting assembly 2. The buffer assembly 3 includes a damping rod 31. A fixing plate 32 is fixedly installed at the bottom of the damping rod 31. Four rotating grooves 33 are opened on the side of the fixing plate 32. A connecting rod 34 is rotatably connected to the inner side of each of the four rotating grooves 33. A moving block 35 is rotatably connected to one end of each of the four connecting rods 34. A sliding rod 36 is slidably connected inside the moving block 35. A buffer spring 37 is sleeved on the outer side of the sliding rod 36.

[0035] The rolling component 4 is disposed at the bottom of the buffer component 3. The fixing component 4 includes a support frame 41, which is fixedly installed at the bottom of the damping rod 31. A rotating shaft 42 is fixedly installed on the inner side of the support frame 41, and a roller 43 is rotatably connected to the outer side of the rotating shaft 42.

[0036] Two vibration damping components 5 are respectively disposed at both ends of the top of the support frame 41.

[0037] Mounting component 2 secures the connection between the traveling wheel and the coal feeder. Buffer component 3 and vibration damping component 5 form a dual vibration damping system to absorb vibrations of different frequencies. Rolling component 4 enables the equipment to move along the track. All components work together to ensure the smooth operation of the traveling wheel.

[0038] The mounting assembly 2 includes a mounting plate 21, with mounting bolts 22 provided inside all four sides of the mounting plate 21. Sliding grooves 23 are provided around the bottom of the mounting plate 21, and the sliding rod 36 is fixedly installed on the inner side of the sliding groove 23.

[0039] Mounting bolts 22 securely fix mounting plate 21 to the bottom of coal feeder 1, and chute 23 provides installation space for slide bar 36 to ensure stable operation of buffer assembly 3.

[0040] Both vibration damping components 5 include a fixing plate 51, which is fixedly installed on the top of the support frame 41. Movable rods 52 are slidably connected to the inside of both ends of the fixing plate 51. Nuts 55 are threadedly connected to the bottom of the outer side of both movable rods 52. Both nuts 55 are located at the bottom of the fixing plate 51. Vibration damping springs 53 are sleeved on the outer side of both movable rods 52. Limiting plates 54 are fixedly installed on the top of both movable rods 52. The tops of both limiting plates 54 are fixedly installed on the bottom of the mounting plate 21.

[0041] The damping spring 53 is normally in a compressed state, providing continuous damping force; the nut 55 can adjust the initial compression of the damping spring 53 to adapt to different vibration intensity scenarios; the limiting plate 54 prevents the moving rod 52 from disengaging from the fixed plate 51, ensuring structural stability.

[0042] The top of the mounting plate 21 is provided with a coal feeder 1, and the tops of the four mounting bolts 22 are all threaded to the inside of the bottom of the coal feeder 1.

[0043] Mounting bolt 22 enables a detachable connection between the mounting plate and the coal feeder 1, facilitating maintenance and replacement of the walking wheel assembly.

[0044] The working principle of the ring-type coal feeder traveling wheel provided by this invention to reduce the failure rate is as follows:

[0045] When the coal feeder 1 is in operation, the roller 43 rolls along the track, driving the equipment to move and feed materials; the vibration caused by the impact of coal or uneven track is transmitted to the buffer assembly 3, the damping rod 31 contracts to buffer the longitudinal vibration, and at the same time the fixed plate 32 drives the connecting rod 34 to rotate, pushing the moving block 35 to slide along the slide rod 36, compressing the buffer spring 37, converting the longitudinal vibration into lateral buffering, and attenuating the vibration energy.

[0046] The residual vibration is transmitted to the vibration damping component 5, and the vibration damping spring 53 is further compressed to absorb the vibration, preventing the vibration from acting directly on the roller 43 and the shaft 42, reducing bearing wear and shaft 42 deformation; the moving rod 52 slides along the fixed plate 51 to ensure that the vibration damping spring 53 extends and retracts smoothly.

[0047] Compared with related technologies, the ring-type coal feeder traveling wheel provided by the present invention, which reduces the failure rate, has the following beneficial effects:

[0048] Through the coordinated structure of mounting component 2, buffer component 3, rolling component 4, and two vibration damping components 5, when the vibration generated by the operation of the coal feeder 1 is transmitted to the buffer component 3, the damping rod 31 contracts to buffer the longitudinal vibration, and the connecting rod 34 drives the moving block 35 to slide along the slide rod 36 and compress the buffer spring 37, converting the longitudinal vibration into lateral buffering. At the same time, the vibration damping component 5 further absorbs the residual vibration, thereby significantly attenuating the vibration energy, avoiding the vibration from directly acting on the roller 43 and the shaft 42, reducing bearing wear, shaft 42 deformation, and severe friction between the wheel and the track, extending the service life of the traveling wheel, effectively reducing the failure rate, and ensuring the continuous and stable operation of the ring coal feeder.

[0049] Second Embodiment

[0050] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application which provides a ring-shaped coal feeder traveling wheel to reduce the failure rate, the second embodiment of this application proposes another ring-shaped coal feeder traveling wheel to reduce the failure rate. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0051] Specifically, the second embodiment of this application provides a ring-shaped coal feeder traveling wheel with reduced failure rate, wherein a rotating component 6 is provided on one side of the mounting plate 21, and a support component 7 is provided at the bottom of the rotating component 6.

[0052] The rotating assembly 6 includes a rotating seat 61, which is fixedly installed on the side of the mounting plate 21. A fixed shaft 62 is rotatably connected to the inner side of the rotating seat 61. Adjusting discs 63 are fixedly installed at both ends of the outer side of the rotating shaft 62. Two adjusting holes 64 are opened on the top of each of the two adjusting discs 63. Positioning bolts 65 are threadedly connected to the inside of both sides of the rotating seat 61. One end of the positioning bolt 65 is engaged with the inner side of the adjusting hole 64.

[0053] The support assembly 7 includes a support frame 71, which is fixedly installed on the outer side of the fixed shaft 62. A movable plate 73 is slidably connected to the bottom of the support frame 71. A track abutment seat 74 is fixedly installed at the bottom of the movable plate 73. A hydraulic rod 72 is fixedly installed at the top of the movable plate 73. The top of the hydraulic rod 72 is fixedly placed on the top of the inner side of the support frame 71.

[0054] The working principle of the ring-type coal feeder traveling wheel provided by this invention to reduce the failure rate is as follows:

[0055] When the equipment is stopped or under maintenance, loosen the positioning bolt 65, rotate the support frame 71 to be perpendicular to the track, and lock the positioning bolt into the corresponding adjustment hole 64 for fixation; then, start the hydraulic rod 72 to push the moving plate 73 to move downward, so that the track abutment seat 74 contacts the track and applies support force to share the pressure of the roller 43; during operation, reverse the operation to retract the support assembly 7 without affecting the normal operation of the traveling wheels.

[0056] Compared with related technologies, the ring-type coal feeder traveling wheel provided by the present invention, which reduces the failure rate, has the following beneficial effects:

[0057] Through the coordinated operation of rotating component 6 and support component 7, when the machine is stopped or under maintenance, the positioning bolt 65 can be loosened to rotate the support frame 71 to the target direction. Then, the positioning bolt 65 is used to lock the adjustment hole 64 for fixation. The hydraulic rod 72 is activated to push the moving plate 73 to bring the rail abutment seat 74 into contact with the rail. No additional support device is required, which can effectively distribute the load-bearing pressure of the roller 43 and avoid deformation or local wear of the roller 43 due to long-term static placement. At the same time, the support component 7 can be flexibly extended and retracted without affecting the normal operation of the traveling wheels, further reducing the equipment failure rate, extending the service life of the traveling wheels, and ensuring the convenience of operation and maintenance and the stability of the ring feeder.

[0058] Third Embodiment

[0059] Please refer to the following: Figure 7Based on the first embodiment of this application which provides a ring-shaped coal feeder traveling wheel for reducing failure rate, the third embodiment of this application proposes another ring-shaped coal feeder traveling wheel for reducing failure rate. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0060] Specifically, the third embodiment of this application provides a ring feeder traveling wheel with reduced failure rate, wherein a threaded hole 10 is provided at one end of the inner side of the slide groove 23, a threaded rod 9 is fixedly installed at one end of the slide rod 36, and a rotating block 8 is fixedly installed at the other end of the slide rod 36.

[0061] One end of the threaded rod 9 is threaded to the inner side of the threaded hole 10.

[0062] The rotating block 8 is disposed on the side of the mounting plate 21.

[0063] The working principle of the ring-type coal feeder traveling wheel provided by this invention to reduce the failure rate is as follows:

[0064] When the buffer assembly 3 needs maintenance, rotate the rotating block 8 to rotate the slide rod 36, and the threaded rod 9 will be unscrewed from the threaded hole 10. The slide rod 36, the moving block 35 and the buffer spring 37 can then be taken out for cleaning or replacement. After maintenance, reverse the operation to fix the slide rod 36 in the slide groove 23.

[0065] Compared with related technologies, the ring-type coal feeder traveling wheel provided by the present invention, which reduces the failure rate, has the following beneficial effects:

[0066] Through the interplay of the threaded hole 10, threaded rod 9, and rotating block 8, when maintaining the buffer assembly 3, simply rotating the rotating block 8 allows the slide rod 36 to be removed from the slide groove 23, facilitating quick disassembly of the moving block 35 and buffer spring 37 for cleaning or replacement. Simultaneously, during installation, rotating the rotating block 8 in the opposite direction ensures the slide rod 36 is securely fixed. The operation is simple and efficient, significantly reducing maintenance difficulty and time costs, and ensuring the continuous operation of the ring feeder.

[0067] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
