Abstract
The utility model discloses an electrical interlocking mechanism for a flame-proof type middle-voltage frequency-speed regulating gate device for mine, the upper part of a gate spindle is bushed in the moving shaft bush and static shaft bush, the moving shaft bush is welded on upper part of the gate spindle, the moving shaft bush base is welded with a spacing bush, the static shaft bush base of the static shaft bush is welded on a flame-proof case, a spacing shaft is disposed via shaft hole of the static shaft bush base, the lower part of the spacing shaft is bushed in the guiding bush, the flame-proof case is welded with a latch shaft bush, the latch shaft bush is bushed with a latch shaft therein, one end of the latch shaft is matched to contact with the spacing bush, while the other end is matched to contact with a commutation late, the commutation plate is disposed with a section of arc concave surface, the arc concave surface is movably matched to connect with the latch shaft. By using the electrical interlocking mechanism for a flame-proof type middle-voltage frequency-speed regulating gate device for mine, the arc concave surface manufactured on the commutation plate is in interlocking match with the latch shaft; by rotating the commutation plate, the left and right displacement of the latch shaft can be regulated to control contact between the latch shaft and the spacing bush in order to securely open the gate cover.
Description
Technical field
The utility model belongs to a kind of flame-proof mine medium voltage converter speed regulating device, particularly a kind of flame-proof mine medium voltage converter speed regulating device door Electricity Federation latch mechanism.
Background technology
Under the coal mine, contain explosive gas atmospheres such as methane, coal dust mixture in the surrounding medium, require according to relevant rules: the colliery must be provided with interlock with the down-hole electric equipment, and door closure can not be opened when power connection; Door closure is opened the back power supply and can not be connected.The colliery should be designed to the structure that general purpose tool can not be removed its interlock with the interlock of down-hole electric equipment.The general more complicated of door Electricity Federation locking device, most latch shaft all is threaded, and during unlatching, need turn latch shaft, and in the narrow and small environment of down-hole, operation is very inconvenient again.
Summary of the invention
The purpose of this utility model provides flame-proof mine medium voltage converter speed regulating device door Electricity Federation latch mechanism a kind of simple in structure, easy to use.
For achieving the above object, solution of the present utility model is: a kind of flame-proof mine medium voltage converter speed regulating device door Electricity Federation latch mechanism, by door closure, handle, door-hinge, latch shaft is formed, described door-hinge top is socketed in moving axis cover and the dead axle cover, moving axis cover bearing is welded on door closure top, be welded with stop collar on the described moving axis cover bearing, the dead axle cover bearing of above-mentioned dead axle cover is welded on the Flameproof box, the axis hole that passes on the dead axle cover bearing is provided with limit shaft, described limit shaft bottom is socketed in the fairlead, the end of limit shaft in fairlead is provided with limit spring, be welded with the locking axle sleeve on the described Flameproof box, be socketed with latch shaft in the described latch shaft, described latch shaft is provided with case spring, and latch shaft one end contacts with the stop collar cooperation, and the other end contacts with the commutation board cooperation, described commutation board is provided with one section circular arc concave panel, and this circular arc concave panel is connected movingly with latch shaft.
Adopt above-mentioned flame-proof mine medium voltage converter speed regulating device door Electricity Federation latch mechanism, the circular arc concave panel and the latch shaft that are processed on its commutation board are linked, under spring action latch shaft all the time near commutation board on the circular arc concave panel, the rotation commutation board can be adjusted the left and right displacement of latch shaft, the control latch shaft contacts with stop collar, thereby reach the purpose of safe opening door closure, this mode is easy and simple to handle, has improved efficient greatly.
