Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor roller disassembly, specifically relating to a belt conveyor roller shaft disassembly device. Background Technology

[0002] Belt conveyor rollers, as key components of underground coal mine transportation systems, are widely used in the roadways, tunneling, and other material transport processes of fully mechanized coal mining faces. With their advantages of large transport capacity, high load-bearing capacity, adaptability to complex working conditions, and long-distance transport, they have become an important guarantee for efficient coal mine production. The structure of a belt conveyor mainly includes components such as a belt storage frame, flame-retardant belt, impact idlers, redirecting rollers, tensioning devices, and transmission devices. Among these, the rollers, as the core components for transmission and redirection, are in large demand, and their performance directly affects the equipment's operating efficiency and safety.

[0003] Disassembly of the bearing is an essential step in the maintenance of rollers. However, traditional maintenance methods often involve ramming the bearing, which poses significant safety hazards: firstly, the impact force can easily cause the bearing to suddenly detach or shatter, resulting in flying metal fragments and potential injuries; secondly, rough disassembly can damage the shaft and mating surfaces, reducing component reuse rates and increasing production costs. Furthermore, the complex and confined working environment in coal mines further amplifies the risks of such operations. Therefore, it is urgent to improve existing bearing disassembly processes and develop safe and efficient maintenance technologies to ensure personnel safety, reduce maintenance costs, and improve equipment reuse rates.

The two shaft removal device frame baffle grooves are disposed on the two shaft removal device frame baffles, the two roller fixing frame grooves are disposed on the two roller fixing frames, the two top shaft mechanism fixing frame grooves are disposed on the two top shaft mechanism fixing frames, and the top shaft mechanism is disposed on the two top shaft mechanism fixing frames.

[0007] Preferably, the protective mechanism includes a fixing clip and a protective cover. The fixing clip is hinged to the fixing plates of the two-sided shaft removal device frame, and the protective cover is hinged to the fixing plate of the one-sided shaft removal device frame.

[0008] Preferably, the fixing clip includes two fixing holes, two fixing screws and two fixing nuts. The two fixing screws pass through the two fixing holes respectively, and the two fixing nuts are screwed to the two fixing screws. The two sides of the fixing clip are respectively hinged to the fixing plate of the shaft removal device frame through the two fixing holes.

[0009] Preferably, the protective cover includes an arc-shaped protective cover plate and a protective cover handle.

[0010] Preferably, the top shaft mechanism includes a tensioning jack, an oil supply pipe, and an oil return pipe, wherein the tensioning jack is connected to the oil supply pipe and the oil return pipe respectively.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model belt conveyor roller removal device effectively prevents roller ejection and bearing splashing through structural design such as fixed grooves and protective mechanisms, eliminating the safety hazards of traditional ramming removal methods, achieving controllable risks and preventable accidents, and ensuring the safety of operators.

[0013] The use of compressed air-driven tensioning jacks replaces manual hammering, achieving mechanized shaft jacking operations. This not only reduces labor intensity but also significantly shortens shaft disassembly time, making it particularly suitable for batch maintenance scenarios and significantly improving work efficiency. The device can be flexibly adjusted according to different roller specifications (such as Φ320×950, Φ400×950, etc.) to adapt to the maintenance needs of various belt conveyor rollers. It can also be extended to the maintenance of equipment involving roller drives in other industries, resulting in high utilization.

[0014] By applying precise force to the shaft, violent damage to the shaft and bearings is avoided, increasing the reusability of the rollers and bearings, reducing the frequency of parts replacement, and thus lowering production costs. While ensuring safe production, it reduces downtime losses and labor costs caused by accidents, providing an efficient and economical solution for equipment maintenance in coal mines and other related industries.
