Description
Technical field
This utility model relates to mining machine technical field, is specially a kind of pure electric combined-type miner built-in power damping fixing device。
Background technology
Mining machine is operationally, owing to exploitation part has dither equipment, the lifting of exploitation rate is had more important impact by this, can by ore grinding, reduce transport difficulty, but whole mining machine is then nuisance vibration by this, long-term dither can cause the connection between device interior connector to loosen, such as loosening between bolt and nut, cause connect between each part shaky, produce displacement, it is difficult to ensure that original installation accuracy of equipment, and dither will also result in the mutual friction of motion between loose fitting simultaneously, cause noise big, loss is high, reduce the series of problems such as service life of equipment, therefore needing a shock-damping structure between winning apparatus and other equipment is realize shock absorption。
Utility model content
The purpose of this utility model is in that to provide a kind of pure electric combined-type miner built-in power damping fixing device, with the problem solving to propose in above-mentioned background technology。
For achieving the above object, this utility model provides following technical scheme: a kind of pure electric combined-type miner built-in power damping fixing device, including base, the upper surface of described base lays guide rail, and base centre position arranges fixed lobe, described fixed lobe both sides are welded with one end of two expansion links respectively, described expansion link adds shock mount away from one end of fixed lobe, described expansion link centre position installs block additional, the side of described block is connected near the end thereof contacts of fixed lobe with spring, one end away from fixed lobe of two springs is connected with the side of the side of left slider and right slide block respectively, described left slider and right slide block lower end are provided with chute and coordinate installation with the slide rail of the fixed lobe left and right sides respectively, bearing plate is installed additional between the upper surface of described left slider and right slide block, the two ends of described bearing plate are connected with left slider and right slide block respectively through bolt, described fixed lobe arranges electromagnetic damping bar, described electromagnetic damping bar bottom is welded with the upper surface of fixed lobe, the described upper end of electromagnetic damping bar contacts installation with the lower surface of bearing plate。
Preferably, described electromagnetic damping bar upper end is hemispherical。
Preferably, offer preformed hole in the middle of described bearing plate, and bottom bearing plate, attach deformation sheet。
Preferably, described deformation sheet is connected with the circuit with current detecting。
Preferably, described expansion link is electric expansion bar and has the function that cuts off self-lock, and the quantity of described expansion link is four and is evenly arranged in the both sides of fixed lobe。
Compared with prior art, the beneficial effects of the utility model are: the spring shock absorption effect that this conventional shock-absorption device of utility model structural change is simple, increase deformation sheet, deformation sheet is accessed the circuit with current detecting simultaneously, the circuital current caused by the deformation of deformation sheet is changed, the frequency of vibration of equipment is recorded by electric circuit inspection curent change frequency, changed by the length of electric expansion bar, also left and right slide block moving left and right on base is realized, thus changing the natural frequency of the structure of whole device, so that the natural frequency of total ensures suitable ratio with the frequency of vibration of equipment, thus avoiding producing resonance, and between expansion link and slide block, add shock mount, reduce collsion damage。
