Problems solved by technology

Due to the large proportion of gangue excavated in the rock roadway, the large impact force of the blast, and the strong traction force of the scraping bucket running back and forth, the guardrails on both sides of the rake machine are deformed and the fixation is not firm. If the wire rope breaks or the rope is thrown during operation, it cannot Covering, can not play a very good protective role, bring great hidden dangers to safety production

Abstract

The invention relates to a guard fence device of a raking machine. The guard fence device comprises a framework made by welding of angle iron, the framework is internally provided with a plurality of steel pipes arranged with the same spacing, and each steel pipe is vertically provided with two fixed screw holes with the same spacing; and an anchor rope penetrates through each steel pipe, is fixedly tightened by bolts through the fixed screw holes and extends out of the corresponding steel pipe. The guard fence device has the advantages of convenience and easiness in use, durable structure and comprehensive safety protection, and the coefficient of safety operations can be improved.

Description

technical field [0001] The invention relates to mining equipment, in particular to a rake machine guardrail device. Background technique [0002] The rake machine plays an important role in mine production. The existing rake machine uses guardrails on both sides as an angle steel frame with a length of 2.2 meters and a height of 0.5 meters. The middle equidistant round steel is arranged and welded. Due to the large proportion of gangue excavated in the rock roadway, the large impact force of the blast, and the strong traction force of the scraping bucket running back and forth, the guardrails on both sides of the rake machine are deformed and the fixation is not firm. If the wire rope breaks or the rope is thrown during operation, it cannot Covering can not achieve a good protective effect, which brings great hidden dangers to safe production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rake machine guardr...
