Utility model content

The purpose of the utility model is to provide a deflection adjustment device capable of timely adjusting the position of the conveyor belt in view of the shortcomings of the prior art.

In order to achieve the above purpose, the utility model adopts a technical solution for a deviation adjustment device for a coal conveyor belt:

A deflection adjustment device for a coal conveyor belt, which includes a base placed on the ground, above which is provided an idler assembly for conveying the conveyor belt, and the idler assembly is fixed on the base by a deflection adjustment mechanism. On the seat, the deflection adjustment mechanism includes a slide rail arranged on the upper surface of the base, a slider is slidably connected to the slide rail, and the idler assembly is fixedly connected to the slider. The free end of the piston rod is fixedly connected to the roller assembly through the connecting piece, and the axial direction of the piston rod of the oil cylinder is the same as the length direction of the slide rail.

When the utility model is working, the roller assembly rotates and the conveyor belt lapped on the roller moves. When the conveyor belt deviates relative to the roller assembly, the oil cylinder is started, and the piston rod of the oil cylinder is extended, and the roller assembly movement so that the conveyor belt overlaps the idler roller assembly.

Compared with the prior art, the beneficial effect of the utility model is: due to the existence of the deviation adjustment mechanism, the oil cylinder cooperates with the slide rail, so that the deviation conveyor belt can be effectively overlapped on the idler roller assembly again.

The oil cylinder is a two-way oil cylinder. The two-way oil cylinder makes the movement of the idler roller assembly more stable.

The base located at the limit position of the piston rod of the oil cylinder is provided with a buffer component, and the buffer component includes a vertical rod arranged on the base, each vertical rod is fixedly connected with an elastic rubber block, and the free end of the elastic rubber block Towards the corresponding end face of the slider. Due to the large inertia of the moving idler assembly, when the idler assembly moves to the limit position of the oil cylinder, the buffer component can effectively absorb the kinetic energy of the idler assembly to prevent damage to the oil cylinder.

The idler assembly includes an idler frame and an idler arranged on the idler frame, and the idler is used to convey the conveyor belt overlapped on the idler.

The roller frame includes a horizontal section skeleton and an inclined section skeleton connected to both ends of the horizontal section skeleton. The free ends of the two inclined section skeletons are arranged obliquely upward. Rollers are installed.
