·The new tire protection device won the national patent
Recently, the tire protection device invented by the Shenhua Coal Group Production Service Center of Shenhua Group won the national utility model patent. In the past, due to the differences in geological conditions of various mines, in order to increase the support force, all mines carried out multiple rows of bolt support on the roof of the roadway and the coal walls on both sides according to actual needs. When the frame-type carriage truck undertakes the transportation task of the fully mechanized mining equipment under the operation well, the tire often rubs against the anchor cable on both sides of the roadway, which directly causes serious damage to the vehicle tire. In the long run, the tire replacement is frequent, which greatly increases the production operation cost. . In order to reduce costs and achieve low-cost operation, the special team technicians invented a tire protection device, which effectively solved the current situation of frequent damage of special vehicle tires. The frame type bracket truck tire protection device is divided into a tire cover body and a shield bracket. The shield body includes a tire bolt inspection hole, a shield fixing block, a bolt hole, and a positioning plate; the shield bracket includes The wire groove and the bolt hole bracket are placed between the tire cover and the vehicle body for connection. By attaching the tire protection device of the frame type bracket truck, the tires of the frame type bracket truck are prevented from being exposed to the outside, thereby effectively reducing the damage of the suspension equipment such as anchor cables on both sides of the mine roadway. “The tire protection device is very practical for the special transportation mode of the trackless rubber wheel in Shendong mining area, which effectively reduces the damage of the exposed anchor cable on both sides of the roadway and prolongs the service life of the special vehicle tire. As of the end of August, it has saved 200 yuan. More than 10,000 yuan, the economic benefits are considerable." The team's special team captain and secretary Zhang Yuping told the media.
