Technical Field

[0001] This utility model relates to the field of mining machinery and equipment, and in particular to an upper support roller device for an iron plate feeder. Background Technology

[0002] In the ore crushing and feeding process in mines, the iron plate machine is one of the key pieces of equipment, and its upper support roller plays an important role in supporting and guiding the trough plate and the ore.

[0003] The traditional iron plate machine has many defects in its upper support roller structure design. On the one hand, it adopts a combination of numerous support rollers and chain rollers. The large number of parts makes the overall structure of the equipment complex, requires high assembly precision, and the installation process is time-consuming and labor-intensive. Moreover, during long-term operation, many rollers are prone to wear and loosening due to frequent operation and uneven force, leading to frequent failures.

[0004] On the other hand, in the old structure, the support roller is mainly responsible for bearing the weight, while the chain roller focuses on maintaining the running trajectory of the chain. The two functions are relatively independent and lack effective integration, making it difficult to take into account both the support and anti-deviation functions. Once the trough plate shifts or the force is unbalanced during the operation of the equipment, it is difficult to adjust and correct it quickly and effectively. This not only affects the stability and continuity of the feed, but may also cause additional wear and damage to the equipment parts.

[0005] In addition, due to the large number of parts and their complex layout, a lot of manpower and time are required to troubleshoot the fault points during maintenance. The maintenance operation space is limited, it is difficult to replace damaged parts, the maintenance cost is high, and frequent downtime due to faults seriously affects the operating efficiency of the equipment and the production schedule.

[0006] Therefore, it is necessary to provide an upper support roller device for an iron plate feeder to solve the above-mentioned technical problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0020] Please refer to the following: Figure 1-4 ,in, Figure 1 A schematic diagram of the structure of the first embodiment of the upper support roller device of the iron plate feeder provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The enlarged schematic diagram of section B is shown below; Figure 4 for Figure 1 The enlarged schematic diagram of section C is shown. A top support roller device for an iron plate feeder includes: Two mounting bases 1, a rotating assembly 2, a lifting assembly 3, and two mounting assemblies 4; The rotating assembly 2 is disposed between the two mounting bases 1. The rotating assembly 2 includes a rotating rod 21 and two rotating heads 22, with the two rotating heads 22 respectively mounted at both ends of the rotating rod 21. The lifting assembly 3 is located at the center of the surface of the rotating rod 21. The lifting assembly 3 includes a lifting ring 31, two mounting rings 32 and multiple fixing bolts 33. The lifting ring 31 is sleeved at the center of the surface of the rotating rod 21. The two mounting rings 32 are respectively connected to the two sides of the lifting ring 31 and sleeved on the surface of the rotating rod 21. The two mounting components 4 are respectively disposed on the left and right sides of the surface of the rotating rod 21.

[0021] Multiple fixing bolts 33 are respectively disposed between the two mounting rings 32 and the rotating rod 21.

[0022] The mounting assembly 4 includes two mounting sleeves 41 and two fasteners 42. The two mounting sleeves 41 are symmetrically fitted onto the surface of the rotating rod 21, and the two fasteners 42 are disposed between the two mounting sleeves 41.

[0023] A disassembly cover 6 is provided on one side of the mounting base 1.

[0024] The lifting ring 31 is used to lift and support the object.

[0025] Two mounting bases 1 serve as the basic support components of the entire roller support device. They are made of high-strength, highly wear-resistant alloy steel and are securely mounted on the frame of the iron plate machine using pre-embedded bolts. The interior of each mounting base 1 features a high-precision bearing mounting groove to accommodate the rotating head 22 of the rotating assembly, ensuring smooth rotation of the assembly. A disassembly cover 6 is located on one side of each mounting base 1. This cover uses a detachable bolt connection, allowing for easy opening of the disassembly cover 6 simply by unscrewing the bolts when inspecting or replacing the rotating assembly or other internal components, greatly improving maintenance convenience.

[0026] The rotating rod 21 is made of solid alloy steel, which has good strength and toughness and can withstand the heavy pressure of ore and trough plate. At both ends of the rotating rod 21, two rotating heads 22 are tightly installed by interference fit. High-precision rolling bearings are installed on the outside of the rotating heads 22. The outer ring of the bearing is tightly fitted with the bearing mounting groove of the mounting seat 1, so that the rotating rod 21 can rotate flexibly between the mounting seats 1, reducing frictional resistance and ensuring the stability of the support roller during operation.

[0027] The lifting ring 31 is made of a special wear-resistant rubber material with anti-slip texture on its surface to increase the friction between it and the trough plate and prevent the trough plate from sliding during the conveying process. Multiple fixing bolts 33 are evenly distributed between the two mounting rings 32 and the rotating rod 21. High-strength bolts are used. By tightening the fixing bolts 33, the mounting rings 32 and the lifting ring 31 are firmly fixed to the rotating rod 21, ensuring that the lifting assembly will not loosen during operation and stably supports the object.

[0028] The mounting sleeve 41 is made of copper alloy, which has good friction reduction and wear resistance. Two fixing parts 42 are set between the two mounting sleeves 41. The fixing parts 42 are high-strength locking nuts. By tightening the fixing parts 42, the distance between the two mounting sleeves 41 can be adjusted, thereby playing an axial positioning role for the rotating rod 21, preventing the rotating rod 21 from axially moving during operation, and ensuring the stability of the roller support device.

[0029] During the intermediate crushing and feeding operation, when the iron plate machine is running, the trough plate and ore to be conveyed are placed on the lifting ring 31 of the lifting assembly 3. The rotating rod 21 of the rotating assembly 2 is equipped with rotating heads 22 at both ends. The rotating heads 22 cooperate with the mounting base 1, so that the rotating rod 21 can rotate flexibly between the mounting base 1. When the iron plate machine runs and drives the trough plate and ore to move, the lifting ring 31 is subjected to pressure, which transmits the force to the rotating rod 21. The rotating rod 21 rotates between the mounting base 1, thereby achieving support and guidance for the trough plate and ore.

[0030] The two mounting sleeves 41 in the mounting assembly 4 are symmetrically fitted onto the surface of the rotating rod 21, and the two fixing parts 42 are set between the two mounting sleeves 41. The mounting assembly 4 plays the role of assisting in fixing the rotating rod 21, ensuring the stability of the rotating rod 21 during operation, and preventing abnormal situations such as axial movement.

[0032] The lifting component 3 is located at the center of the rotating rod 21. The lifting ring 31 can support the object. Combined with the overall structural design, it can better maintain the stability of the equipment operation while bearing the weight, effectively taking into account the functions of load support and anti-deviation.
