Abstract
The invention relates to the technical field of mining chains, in particular to a chain with a compact eccentric angle. The eccentric angle compact chain comprises long chain structures which are connected by round section welding flat rings arranged at intervals through an eccentric angle forging vertical ring. The eccentric angle vertical ring, namely the included angle formed by the pitch center line and the straight arm, realizes the increase of the vibration of the scraper and the chain when being subjected to large load in the practical application process. Thereby making the chain transmission smoother in the actual work.
Description
Technical Field
The invention relates to the field of structural design of a mining compact chain. Particularly, the invention aims to increase beneficial vibration of a chain when the chain is subjected to a large load in the running process, so that the chain transmission is smoother.
Background
Chains such as compact chains are used in the underground coal mining industry as transmission chains for driving scraper conveyors. Such scraper or chain scraper conveyors can be formed by two endless motor-driven conveyor chains, on which the scraper connected to the chain between the two chains is fixed. The strippers, such as coal, are conveyed by the scrapers.
In the process of adopting a driving device with higher power for the scraper, the requirement of bearing load of the transmission chain is correspondingly improved. In some conditions, the strippings accumulate too much. The vibration of the transmission chain is increased, and the smooth transmission of the transmission chain is facilitated.
Disclosure of Invention
The object of the invention is to increase the beneficial vibrations during operation. The new chain is a welding ring, and the vertical ring is a forging ring. An included angle is formed between the pitch center line of the vertical ring and the straight arm through the eccentric angle, so that the vibration is increased during the operation.
The technical scheme adopted by the invention for solving the technical problems is as follows: consists of a circular section welding flat ring 1 and an eccentric angle forging vertical ring 2; the round section welding flat rings 1 arranged at intervals are connected into a long chain through an eccentric angle forging vertical ring 2.
Furthermore, an eccentric angle forges the vertical ring 2, the eccentric angle vertical ring, namely, a pitch center line forms an included angle alpha with the straight arm, and the alpha is more than or equal to 2 degrees.
The invention has the beneficial effect that when the load of the chain is overlarge, the vibration of the chain is increased. The chain transmission is smoother.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 schematic diagram of an eccentric angle compact chain
FIG. 2 is a schematic view of an eccentric angle forged vertical ring
In the figure: 1. welding a flat ring on the circular section; 2. and forging the vertical ring by an eccentric angle.
The specific implementation mode is as follows:
in the figures 1-2, the eccentric angle compact chain is composed of circular section welding flat rings and eccentric angle forging vertical rings, and the circular section welding flat rings arranged at intervals are connected into a long chain through the eccentric angle forging vertical rings. The eccentric angle forges the vertical ring, the vertical ring of eccentric angle, namely the pitch center line forms an included angle alpha with the straight arm, alpha is more than or equal to 2 degrees. When the load of the chain is overlarge in practical application, the vibration of the chain is increased. The chain transmission is smoother.
The present embodiment should not be construed as limiting the present invention, but any modification made based on the spirit of the present invention should be within the scope of protection of the present invention.
