Abstract
The invention discloses an application method of a wood board conveying device. The method comprises the following steps that a belt is wound around a rectangular frame firstly, and a pressure sensor at the tail end of a first air cylinder conducts detecting and recording on the rectangular frame; when the recorded acting force is smaller than the limited pressure value, the pressure sensor conducts control to start the first air cylinder to start to contract, a spring is stretched, pull force generated by the spring pulls the rectangular frame in the contraction direction of the first air cylinder, meanwhile, the output ends of two second air cylinders contract, and the tension of the belt is reset through pulling of a traction wire to a ferrule; and when the acting force recorded by the pressure sensor is larger than the limited pressure value, the output end of the first air cylinder stretches out in the direction right opposite to the rectangular frame, the spring is compressed, elastic force generated through deformation of the spring pushes the rectangular frame, the output ends of the two second air cylinders are kept to move in the same direction with the first air cylinder, pulling of the traction wire is stopped, and the tensioning force of the belt repeatedly returns to be normal.
Description
Technical field
The present invention relates to belt conveyor, a kind of application method of plank conveyer is specifically referred to.
Background technology
Belt conveyor generally comprises traction piece, bearing carrier, drive device, tensioning apparatus, change course device and supporting member etc., and traction piece is used to transmit tractive force, can take conveyer belt, haulage chain or steel wire rope；Bearing carrier is used to bear material, there is hopper, bracket or suspender etc.；Drive device, with power, is typically made up of to conveyer motor, decelerator and brake (finisher) etc.；Tensioning apparatus typically has two kinds of screw and Weight type, can make traction piece adhere to must tension force and sag, with ensure belt conveyor run well；Supporting member is used to support traction piece or bearing carrier, can take carrying roller, roller etc..With traction piece belt conveyor equipment construction characteristic be：Material is transported to be mounted in the bearing carrier linked together with traction piece, or be directly installed on traction piece (such as conveyer belt), traction piece bypasses each roller or sprocket wheel joins end to end, form the closed circuit comprising the You Zai branches for transporting material and the return run for not transporting material, the continuously active conveying material of application traction part.
Common belt conveyor is after a protracted use, belt occurs certain relaxing, cause the material crank on belt, or the efficiency of transmission drastically declines, now common practice is to carry out the regulation of rate of tension to belt using tensioning apparatus, so that belt recovers normal operating level again, but during the regulation of tensioning apparatus, usually belt is pulled to increase the tensioning dynamics of belt, and when being pulled to belt, the dynamics assurance of pulling is bad will to cause that belt is excessively tight, increase the live load of belt conveyor, if drag force is spent small, belt excessively relax, the efficiency of transmission of belt is low.
