Abstract

The invention belongs to the technical field of design and manufacturing of coal mine underground multifunctional carry-scraper auxiliary equipment, and provides a quick-changing tipping trailer for a thin seam. According to the quick-changing tipping trailer, underground material conveying and unloading functions of a carry-scraper can be achieved, diversity of the functions of the carry-scraper is further improved, the types of equipment are reduced, and the single productivity is improved. The main structure of the quick-changing tipping trailer is composed of a quick-changing device connected with the multifunctional carry-scraper, a device connecting part, a single-oil-cylinder push plate discharging device, a traveling device, a trailer body, a down-opening type discharging door and a hydraulic device. According to the quick-changing tipping trailer, the coal mine underground multifunctional carry-scraper is used as a carrier, a hydraulic system of the carry-scraper provides power for discharging and braking of the trailer, a quick-changing connecting frame of the multifunctional carry-scraper is connected with the quick-changing device of the trailer, the quick-changing device and the tipping trailer body are connected through the device connecting part, and an arrangement space is provided for a pushing device by the device connecting part. A back pushing type three-level oil cylinder is used for pushing a push plate to push out materials backwards along guide rails to complete discharging, and the problem that self-discharging and quick changing of a dumper cannot be achieved due to the fact that an existing thin-seam coal mine well is low is solved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of multifunctional scraper auxiliary equipment in coal mines, and in particular relates to a thin coal seam quick-change dump truck. Background technique [0002] With the continuous improvement of the modernization level of coal mines in our country, the trackless auxiliary transportation method has been widely promoted in our country, especially the multi-functional scraper in the coal mine has become one of the indispensable equipment in the trackless auxiliary transportation system of coal mines. However, there are huge differences in the mine conditions of various coal mines, especially the existence of a large number of thin coal seam mines makes the existing equipment unable to fully meet their production needs, so that coal mining enterprises must be equipped with more types of equipment to meet the working conditions of thin coal seam mines, not only This increases the equi...
