Description

Technical Field

[0001] The utility model belongs to the field of belt conveyor belt changing equipment, and uses a crawler and synchronization to complete the belt changing work of the belt changing device. It is applicable to large inclination places, and particularly relates to a belt changing device for a large inclination belt conveyor. Background Art

[0002] As the most important transportation equipment in the continuous transportation of modern industrial bulk materials, belt conveyors are widely used in industries such as coal mines, metallurgy, and chemical engineering. As the main transportation machinery in coal mines, belt conveyors mainly have two systems: horizontal transportation and inclined transportation. Compared with other types of transportation machinery, it has many advantages such as long distance, large transportation volume, and continuous transportation. It is easier to achieve in a controlled manner, and its performance is more stable and reliable. In recent years, with the gradual deepening of coal mining and the update of mining technology, belt conveyors have long become an essential important transportation machinery in automated mining transportation, and their transportation efficiency is the key factor affecting the safe and efficient production of coal.

[0003] Existing belt changing processes all have some drawbacks. The belt changing process of the alternative belt pulling method is discontinuous, wasting a lot of time. During the belt changing process, the storage of the old belt and the laying of the new belt are carried out separately. Belt changing requires production suspension, wasting time and having a large working intensity. In the old belt connecting to new belt method, a winch is required to cooperate with manual operation. If the conveyor belt slips and slides down on the drum during manual operation, it will seriously affect the personal safety of the belt changing personnel and even affect the facilities in the roadway. In the research of rapid belt changing devices, some belt changing devices have a relatively narrow applicable scenario, applicable to replacing conveyor belts in underground horizontal roadways or roadways with relatively gentle slopes, and not applicable to large inclination places. Some belt changing operations need to be repeated multiple times, and the workload of replacing the entire conveyor belt is huge, resulting in waste of manpower, material resources, and economic losses. Some belt changing devices also have multiple actuators, and in the actual application process, their synchronization effect needs to be considered. To ensure a good belt changing effect, the synchronization problem of multiple actuators needs to be solved. Therefore, it is urgent to research and develop a device that can achieve continuous belt changing. Content of the Utility Model
