Problems solved by technology
[0005] The object of the present invention is to provide a support device for fracture-proof gypsum mining, to solve the problem that most of the gypsum mines proposed in the above background technology are mainly underground mining, and in the mining of gypsum mines, a large amount of support is required. However, some support devices have less bearing capacity when supporting, and when the support on the top is under greater pressure, it is easy to break, which increases the safety hazards of the staff in the roadway

The invention discloses an anti-fracture supporting device for mining a gypsum mine, and relates to the field of machineries. The anti-fracture supporting device comprises a bottom plate. A cavity isformed in the bottom plate, the left side of the bottom of the cavity is fixedly connected with a motor, and two threaded rods are arranged in the cavity. The lower end of one threaded rod is fixedlyconnected with the top end of an output shaft of the motor, and the bottom end of the other threaded rod is rotationally connected with the bottom of the cavity through a bearing. Rod walls of the twothreaded rods are sleeved with gears, the two gears are jointly and rotationally connected with a chain, and the top ends of the two threaded rods penetrate through the upper portion of the cavity and are in threaded connection with threaded sleeves. Circular holes matched with the threaded rods are formed in the upper end of the bottom plate. according to the anti-fracture supporting device formining the gypsum mine, the motor drives the sleeves to rotate upwards through rotation of the threaded rods, the sleeves apply pressure upwards to drive springs, supporting rods and a top plate to move upwards, and the top plate can be prevented from being fractured when bearing large pressure.
Description
technical field [0001] The invention relates to the field of machinery, in particular to an anti-fracture support device for gypsum mining. Background technique [0002] More than one hundred years ago, people found that gypsum ore could be turned into an applied material through a simple firing method, and officially started the research and utilization of gypsum. With the development of industry and construction in modern times, gypsum has been used As the main building material, it has been developed rapidly and used in large quantities. In ancient times, people also discovered another function of gypsum, which is the medicinal function. The manufacture of gypsum board: the natural gypsum ore is crushed, smelted, and then ground. After a series of processing procedures, it is processed into the form of anhydrous gypsum powder, which can be applied in various scenes we need. In addition to being used as decorative materials, such as gypsum putty, gypsum is mostly used as b...
