Description

Vertical jack dismouting machine

Technical Field

The utility model relates to a dismantlement and the installation technical field of jack specifically are vertical jack dismouting machine.

Background

With the progress of the times and the development of science and technology, our country gradually develops towards large machines and large equipment in the field of machines. The method has been gradually moved to the front of the world in the aspects of the production of large airplanes, the construction of high-speed rails, the manufacture of super-tonnage ships, the construction of skyscrapers and the like. Meanwhile, coal enterprises in China are developing towards millions of tons of mines, the improvement and the combined upgrading of small coal mines are promoted, and coal mine equipment is gradually developed towards a large mining height and a fully mechanized mining technology. Meanwhile, manufacturing and repairing units of the large coal mine machinery are examined, so that the manufacturing and repairing units are prompted to follow the pace of the era, and the manufacturing and repairing units are developed towards a high-efficiency, energy-saving and high-quality production process and are changed into excellent enterprises of a new era.

In the conventional concept of the repair industry, work is slow and delicate, and in order to accomplish high quality repairs, our repair workers are careful and unrelenting in the repair process, but are extremely inefficient. Nowadays, coal excavation gradually develops towards large mining height, namely ten million tons of mines, and meanwhile, coal mining equipment is also changed into large-scale equipment. Therefore, the valves and jacks used are gradually changed to be large-sized, the quantity of the valves and jacks is gradually increased, and the original speed of completely manual repair is difficult to keep pace with the increasing repair quantity in the development.

In the mine, the working condition is seriously deteriorated due to severe and variable environment, so that the support 9 is in an overload running state for a long time. For the jack used for the support 9 for well-out repair, rust spots are more likely to be generated, and various corrosion and impact injuries are inevitable. In the process of disassembling small-size jack, we find that the degree of difficulty is increaseed year by year, lead to disassembling to waste time and energy inefficiency, and because the more mine of waste rock a bit, the environment is especially abominable, lead to the jack corrosion serious, the manual work is disassembled and has been hardly taken apart, the disability rate also increases year by year, the reinstallation of jack also is very hard simultaneously and is wasted time and energy, and because the more mine of waste rock a bit, the environment is especially abominable, lead to the jack corrosion serious, the manual work is disassembled and has been hardly taken apart, the disability rate also increases year by year.
