ng etc. conveyer belt run intensity of leaning towards and go on a kind of protector that call the police, used in touching off emergency shutdown automatically when the conveyer belt simply runs seriously too sometimes. What employ extensively runs and leans towards the switch and generally runs and leans towards the switch for passive machinery type two grades at present. Run and lean towards the switch to install fixedly on the bringing type conveyer both sides support according to certain interval (about 50m), run gyro wheel part to lean towards switch deviate from border of conveyer belt that centre turn round produce the deflection pinch, touch off the joint movements of the switch when it is transferred to certain angle that the gyro wheel leans towards. Usually one strip to run, lean towards switch close joint insert person who bring divideshut brake of conveyer control return circuit or call the police, point out device connect in series, often all conveyer。 As to long conveyer of bringing etc. very, adopt, run, lean towards switch divide into groups in the way to insert by stage along the line sometimes Skid turn on or off Skid switch to used for, measure conveyer belt with transmission sliding of cylinder and go on a kind of protector that call the police, can be used in touching off emergency shutdown automatically when the conveyer belt skids. It is a kind of paratively serious trouble phenomenon to skid, the reason may overload, the conveyer belt is hindered, taken brokenly by the card, the cylinder is seized and urging the rotational speed of the electrical machinery to unusually wait a moment, for instance may cause serious accidents such as serious damage of the apparatus, fire and bodily injury,etc. if not shutting down in time。 Kinds of the switch are many to skid, operation principle and detection method have nothing in mon with each other. Divide according to detection method, have, measure 7 conveyer belt pace and touching, skidding switching while being wheeled pared with standard pace established directly, measure from the rotational speed of the driving wheel and switch of skidding pared with standard rotational speed established, have difference measure cylinder rotational speed and conveyer belt pace and contrast type pared to go on skid switch at the same time。 Divide according to internal operation principle, there are magism hindering types, magic electricitying type, photosensitive type,etc.. Skid switch device can offer, transport signal with linear velocity or rotational speed of cylinder reveal and export in real time also partly. and split open and close It is to measure a longitudinal a kind of protector that tore and called the police of conveyer belt to tear and split open and shut in, can be used in touching off emergency shutdown automatically when the conveyer belt is torn. Majority tear, take place, in conveyer belt tail clan hopper export, scratch, blow, wear conveyer belt even because the heavy hard things in the supplies are blocked and fallen in the hopper exit, it is with support and asking。
