【正文】 roblems in of practical application, domestic products lack, improve, make a lot of problems not solved pletely for a long time. For many years, domestic brand low price petition cause product quality and after sale service quality can make user to be satisfied each other, and performance and quality to the apparatus of user in the coal, electricity, petrochemical industry, port,etc. are expected very much, they would rather often spend several times even price in the domestic products of more than ten times choosing the foreign imported brand products. On the whole, person who bring conveyer protector products have function single, performance lag behind, structure plicated, appearance coarse, dependability shorting such as being poor at home. The advanced product market is basically dismembered by foreign countries brand, there is not a brand with stronger petitiveness and influence yet at home. In addition, it is a very different important reason of bringing type conveyer protector product quality at home too to lack the sector standard. In fact, the bringing type conveyer protector market demand of the products is very enormous, the domestic producer only changes the idea, take charge of quality severely, fully utilize the latest technology, developing the new products constantly according to market 9 demand, can certainly reseize the advanced market that the foreign brand is being captured.。 Install and draw the line type switch in the conveyer belt low。 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。 As to long conveyer of bringing etc. very, adopt, divide into groups the way to insert by stage along the line pull switch sometimes. Run and lean towards the switch Run, lean towards switch used for, measure conveyer operation course of bringing 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 swi
