Abstract
The invention discloses a wood transferring mechanism. The wood transferring mechanism comprises a workbench, a traction wire and a rectangular frame. A belt is wound around the rectangular frame, and the workbench is connected with the rectangular frame through a pulley set and the traction wire. A first air cylinder is arranged on the workbench. The pulley set is composed of four pulleys, the two pulleys are arranged on the long edge, close to one side of the workbench, of the rectangular frame, and the rest two pulleys are symmetrically arranged on the two sides of the output end of the first air cylinder with the axis of the first air cylinder as an axis. A pressure sensor is arranged at the output end tail of the first air cylinder. After the initial end of the traction wire is fixed to the workbench, the traction wire starts to be wound around the four pulleys and the pressure sensor till the tail end of the traction wire is connected with the output end of a second air cylinder. The pressure sensor is electrically connected with the first air cylinder and the second air cylinder. According to the wood transferring mechanism, the situation that due to tensioning degree changes, the transmission efficiency of the belt is reduced or the work load of the belt is increased is avoided, and the work stability of a belt conveyor is improved.
Description
Technical field
The present invention relates to belt conveyor, a kind of transshipment acitivity of timber 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.
The content of the invention
It is an object of the invention to provide a kind of transshipment acitivity of timber, the convenient regulation to belt tightening, it is ensured that the belt moment keeps optimal rate of tension, the job stability of belt conveyor is improved.
The purpose of the present invention is achieved through the following technical solutions：
A kind of transshipment acitivity of timber, including workbench, draught line and rectangle rack, belt bypasses rectangle rack, the workbench passes through assembly pulley, draught line is connected with rectangle rack, the first cylinder is provided with the workbench, the assembly pulley is made up of 4 pulleys, two pulleys are arranged on rectangle rack and are close on the side long of workbench side, remaining two pulleys are arranged on the both sides of the first cylinder output end with the axis of the first cylinder as axial symmetry, pressure sensor is installed at the first cylinder output end end, also include fixed the second cylinder on the table, the initial end of the draught line starts to bypass four pulleys and pressure sensor after being fixed on workbench, until the end of draught line is connected with the output end of the second cylinder, the pressure sensor respectively with the first cylinder, second cylinder is electrically connected；Displacement transducer is also equipped with the output end of first cylinder, institute's displacement sensors are electrically connected with the display screen of outside.
The present invention is operationally, belt bypasses rectangle rack, the active force that be subject to for rectangle rack and belt by the pressure sensor at the first cylinder output end end carries out detection record, when the active force of record is less than the pressure value for limiting, pressure sensor will control to start the first cylinder setting in motion, so that draught line is prominent to the direction just to rectangle rack, and the output end of the second cylinder starts to be moved to the track in opposite direction with the first cylinder moving simultaneously, rectangle rack is pullled by draught line so that the tension force of belt is replied；When the active force of pressure sensor record is more than the pressure value for limiting, the output end of the first cylinder bounces back to back to the direction of rectangle rack, that is the first cylinder output end stops pulling rectangle rack by draught line, the output end of the second cylinder keeps rightabout motion with the first cylinder simultaneously, stopping is pullled draught line, so that the tensile force of belt repeats back to normal, belt is avoided because the live load of efficiency of transmission reduction or belt caused by rate of tension change is increased, the job stability of belt conveyor is improve.Wherein, when the first cylinder is pullled rectangle rack by draught line, the displacement that displacement transducer can output it end is accurately detected, output simultaneously to outside display screen shows, accurate recording is made with to each belt adjustment, it is convenient to provide technical basis when belt parameter is adjusted in the later stage.
Also include roller, the outer wall of the roller is contacted with belt madial wall, and the side long activity of the rectangle rack runs through and in the middle part of the roller.The roller of setting, it is possible to increase the contact area between rectangle rack and belt so that the regulation accuracy of the first cylinder and two the second cylinders is further improved.
The roller is rubber coated pressure bowl.
The present invention compared with prior art, has the following advantages and advantages：
1st, improve the job stability of belt conveyor because of efficiency of transmission reduction caused by rate of tension change or the live load increasing of belt present invention, avoiding belt；
2nd, the roller that the present invention is set, it is possible to increase the contact area between rectangle rack and belt so that the regulation accuracy of the first cylinder and two the second cylinders is further improved.
