Description
Technical Field
The invention relates to a tensioning device of a horizontal pipe chain machine.
Background
The pipe chain conveyer is a continuous conveyer for conveying powder, small granular and small block-like bulk materials, and can be used for horizontal, inclined and vertical combined conveying. Is generally used in fine chemical industry, pesticide ore, building material, food industry and the like. The pipe chain conveyor consists of a driving mechanism, a chain and a pipeline, and the chain needs to be tensioned when the pipe chain conveyor works. The tightness can easily be ensured during assembly, but after a period of continuous operation the chain becomes loose due to wear of the chain, the sprocket, the shaft, etc. This variation is affected by many factors such as the load on the conveyor, the working environment, etc., and therefore, a device for adjusting the tension of the sprocket is highly desirable.
Disclosure of Invention
In order to solve the technical problem, the invention provides a tensioning device of a horizontal pipe chain machine, which can be improved aiming at the defects.
A tensioning device of a horizontal pipe chain machine comprises a fixed box body, a sliding box capable of sliding in the box body, a chain wheel shaft and a chain wheel arranged in the sliding box, and a tensioning mechanism capable of keeping the sliding box tensioned.
Supporting mechanisms are arranged below two side surfaces of the box body and can support the sliding box; positioning mechanisms are arranged above two side surfaces of the box body, and the positioning mechanisms can position the sliding box; the support mechanism and the positioning mechanism define a sliding track of the slide box.
The outer contour of the slide box is slightly smaller than the inner contour of the box body, and the slide box can slide in the box body.
And a chain wheel shaft and a chain wheel are fixedly connected in the sliding box.
The tensioning mechanism includes: the sliding box comprises a pull rod on the sliding box, a spring on the pull rod, a spring support and an adjusting sleeve, wherein one end of the pull rod is provided with a thread, and an adjusting nut is matched on the thread. The spring support, the spring, the adjusting sleeve and the adjusting nut are sequentially arranged on the pull rod and keep the spring in a compressed state.
And the other side surface of the box body is provided with a pull rod hole, and the pull rod hole can enable the pull rod to extend out of the pull rod hole.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings.
As shown in figures 1-5, the tensioning device of the horizontal pipe chain machine comprises a fixed box body, a sliding box capable of sliding in the box body, a chain wheel shaft and a chain wheel which are arranged in the sliding box, and a tensioning mechanism capable of keeping the sliding box tensioned.
The lower parts of two side surfaces of the box body are respectively provided with 5 supporting bolts, the supporting bolts are screwed into the box body, and the circular head parts of the supporting bolts can support the sliding box; 1 positioning strip is respectively arranged above two side surfaces of the box body, the positioning strips are fastened on the box body through positioning strip fastening bolts, and the positioning strips can position the sliding box to prevent the sliding box from inclining under the tension of the chain; the supporting bolt and the positioning strip jointly define the sliding track of the sliding box.
The outer contour of the slide box is slightly smaller than the inner contour of the box body, and the slide box can slide in the box body. A chain wheel shaft and a chain wheel are fixedly connected in the sliding box.
The tensioning mechanism includes: the slide box comprises a pull rod on the slide box, a spring on the pull rod, a spring support and an adjusting sleeve, wherein one end of the pull rod is provided with a thread, and an adjusting nut is matched on the thread. The spring support, the spring, the adjusting sleeve and the adjusting nut are sequentially arranged on the pull rod, and the spring is kept in a compressed state.
The other side of the case is provided with a pull rod hole (not shown) through which the pull rod can extend.
During operation, the sliding box keeps balance under the action of the elastic force of the spring and the pulling force of the chain, and if the tension degree of the chain is not enough, the sliding box can be pulled by the spring, so that the tension degree of the chain is ensured.
In addition, the tightness of the chain can be changed by adjusting the bolts according to requirements.
