Abstract
The utility model discloses an impact-resistant scraping plate which comprises an upper plate, an upper elastic element, a lower plate, bolts, a chain ring I, a chain ring II and a chain ring III. The upper plate is internally provided with a hollow, the left side and the right side are respectively provided with a chain ring notch, the upper elastic element and the lower elastic element are arranged up and down and are arranged at the hollow of the upper plate, the chain ring II is horizontally arranged between the upper elastic element and the lower elastic element, the chain ring I is connected with one end of the chain ring II through the left notch of the upper plate, the chain ring III is connected with the other end of the chain ring II through the right notch of the upper plate, and the lower plate is connected with the upper plate through a bolt. The impact-resistant scraping plate can realize the elastic connection between the chain and the scraping plate, and reduces the impact load applied to the chain when the scraping plate is impacted randomly, thereby protecting and prolonging the service life of the chain.
Description
Technical Field
The present utility model relates to an impact-resistant flight for reducing damage to a chain due to random impact loads.
Background
At present, a mine scraper and a mine chain are rigidly connected, taking a scraper for a coal mine as an example, when large coal blocks randomly fall on the scraper in the operation process of a conveyor, great impact is caused on a traction chain of the conveyor, and the chain is broken frequently under a large impact load, so that the conveyor cannot work normally. In view of this, the present utility model has been made in a particular way to reduce the random impact load and increase the service life of the blade and chain.
Disclosure of Invention
The utility model aims to provide an impact-resistant scraping plate, which aims to solve the problems.
In order to achieve the above object, the present utility model relates to an impact-resistant screed comprising an upper plate 1, an upper elastic element 2, a lower elastic element 3, a lower plate 4, bolts 5, a link I6, a link II 7, a link III 8.
Further, the impact-resistant scraping plate is characterized in that a hollow 9 is arranged in the upper plate 1, and a left notch 10 and a right notch 11 of a chain ring are respectively arranged on the left side and the right side of the upper plate; the upper elastic element 2 and the lower elastic element 3 are arranged at the hollow 9 of the upper plate 1 in an up-down arrangement manner; the chain ring II 7 is horizontally arranged between the upper elastic element 2 and the lower elastic element 3; the chain ring I6 is connected with one end of the chain ring II 7 through the left notch 10 of the upper plate 1. The chain ring III 8 is connected with the other end of the chain ring II 7 through the right notch 11 of the upper plate 1.
Further, the lower plate 4 is provided with a bolt bayonet 12, and the lower plate 4 is connected with the upper plate 1 through bolts 5.
The utility model relates to an impact-resistant scraping plate, which is characterized in that when being installed: the upper elastic element 2 is firstly arranged in the upper plate 1, the chain is formed by chain rings such as chain ring I6, chain ring II 7, chain ring III 8 and the like, then the chain is arranged in the upper plate 1, the lower elastic element 3 is arranged in the upper plate 1, and finally the lower plate 4 is connected with the upper plate 1 by bolts 5.
The utility model has the advantages and beneficial effects that:
The impact-resistant scraper can reduce chain damage caused by random impact load and prolong the service lives of the scraper and the chain without affecting the rated load of the scraper.
