AI Technical Summary
During the unloading process of existing mobile belt unloaders, due to the pulling force of the belt, it is difficult for the unloading sports car to stop accurately, which easily leads to inaccurate coal drop points and collision and deformation of the unloading chute and the limit stop. Long-term use will cause the chain to break or be lengthened, affecting coal washing production.
Design a sports car shoe resistance device for unloading on a belt conveyor, including a support frame, an electro-hydraulic push rod and shoe resistance. When the unloading sports car needs to stop, the electro-hydraulic push rod and the brakes start together, and the sliding boots resist the movement of the unloading sports car to prevent the wheels from rotating and reduce the impact of the belt pulling force on the chain.
Effectively assist in unloading sports car parking, reduce chain damage caused by belt pulling force, reduce the incidence of failure, and improve the stability and safety of coal washing production.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of belt transportation, in particular to a sliding shoe blocking device for a material unloading sports car on a belt conveyor. Background Art
[0002] Due to the needs of production technology, coal preparation plants use mobile belt unloaders to transport clean coal to the coal bunker for floor loading. Most of the existing mobile belt unloaders are designed in the form of an upper and lower two-layer structure. Figure 2 The lower part is the main frame structure of the mobile belt unloader, and the upper part is designed to be a driving device composed of a motor 3, a reducer 2, a sprocket 4, and a chain to control the wheel to move forward and backward to select the point for loading. When the unloading sports car stops at a fixed point, the belt will produce a certain pulling force on the unloading sports car. Therefore, the unloading sports car will still slow down and move in the direction of the belt operation, making the coal landing point inaccurate, and accidents such as the unloading chute 5 colliding with the limit block 7 and causing deformation often occur. Even if a brake with a larger braking torque is replaced to brake the motor wheel, the pulling force generated by the belt operation cannot be eliminated. Under the action of the pulling force, the sports car roller will tighten the chain, and long-term use will cause the chain to break or be stretched. After the chain is stretched, it is easy to be off the chain, which seriously affects the coal washing production and is extremely inconvenient to repair. Utility Model Content
[0003] The utility model aims to solve the above problems, thereby providing a sliding shoe blocking device for a material unloading sports car on a belt conveyor.
