Abstract

The present invention relates to a method for regulating offset of conveyer belt, and is characterized by that the belt moved to one side can be contacted with touch contactor, then the time delay relay gives out signal, the electric block positioned at offset direction same side can be used for tightly pulling the driven drum, and when the time delay relay does not give out signal, the upper camera instrument behind driven drum can give out signal to start the electric block to tightly pull the driven drum. Said invention can promptly and reliably correct offst so as to ensure normal operation of conveyer belt.

Description

A kind of travelling belt tuningout method

Technical field

The present invention relates to a kind of travelling belt tuningout method, be applicable to the belt tuningout that material needs belt to carry.

Background technology

Belt is widely used for various cargo handling operations as a kind of load transfer device of solid material, has greatly improved work efficiency, has brought very big facility.But when the belt conveyor et out of order, consequence is also very serious.The belt conveyor et out of order generally have belt deviation, belt to come unstuck or/and thread off, follower fault etc. initiatively, in case break down, will cause part or whole production system to be stopped transport.Certain state-owned one large-scale fertilizer enterprises is exactly partly to stop transport five times because of the belt deviation accident causes process units between the more than ten years that process units goes into operation, all stop production three times, economic loss reach millions of more than.According to the analysis of statistical data that belt breaks down, particularly length is after the belt more than 100 meters is correctly installed place in operation when a belt, and its main fault is exactly a sideslip.Sideslip refers to that promptly when belt movement, the belt amplitude of fluctuation is excessive, and the line of centers of its end wise departs from the line of centers of whole belt bracing frame end wise.In fact, belt sideslip in motion process is that inevitably key is its sideslip degree, and the sideslip that only the continuous running to belt is caused a devastating effect usually in the real work just is referred to as " sideslip ".Sideslip is in case take place, and as untimely processing, the moving situation of belt will worsen rapidly, cause material, wearing and tearing with Louing, severe patient even meeting and break belt, interruption entire job link.

At present, generally, the tuningout of belt all utilizes chain block to carry out by the maintainer at the scene, so have to carry out handling labor by strengthening manual inspection, be placed in mostly in the comparison rugged environment owing to belt simultaneously, make handling labor very difficult, and manual inspection is always free at interval, can not guarantee in time belt generation sideslip to be adjusted.

Summary of the invention

The purpose of this invention is to provide travelling belt tuningout method, be applicable to that material needs the problem of mechanism's tuningout of belt conveying.

The method applied in the present invention is, belt 2 is behind a direction sideslip, belt 2

tactility tentaculums

3 or 5,

slug relay

4 or 6 provides signal, sideslip direction homonymy electric block 9 or the driven cylinder 7 of 10 tensions, when

slug relay

4 or 6 did not provide signal, video camera 8 provided signal directly over driven cylinder 7 backs, started electric block 9 or the driven cylinder 7 of 10 tensions.

Belt 2 forms closed-loop and drives operation by drive roll 1 by belt tensioning drum 12 and several auxiliary cylinders 14 of drive roll 1, driven cylinder 7 and band weight case 13, driven cylinder 7 passes through bolted connection with bracing frame 11, under the action of gravity of weight case 13, driven cylinder 7 is at the high order end in the long waist shaped hole of bracing frame 11, driven cylinder 7 can slide along long waist shaped hole direction down by

electric block

9,10 effects, and the left and right sides of belt 2 is separately installed with

mechanorecepter

3,5 and slug relay 4,6.Under the situation of zero load, the time parameter of

debugging mechanorecepter

3,5 and belt 2 distances and

slug relay

4,6, when deviation phenomenon appears left in belt, behind the belt 2 contact left side mechanorecepters 5, time-delay slug relay 6 provides signal and makes left side electric block 10 tightening belt cylinders 7 left ends, makes the belt of sideslip move right normal until automatic recovery gradually; When deviation phenomenon appearred to the right in belt 2, behind the belt 2 contact right side mechanorecepters 3, time-delay slug relay 4 provides signal made right side electric block 9 tightening belt cylinders 7 right-hand members, makes the belt 2 of sideslip be moved to the left until automatic recovery normal gradually.

Directly over driven cylinder 7 backs monitoring device 8 is installed and is observed belts 2 running conditions, when belt 2 sideslips and

slug relay

4 or 6 when not providing signal, operating personal starts the source switch that is located at control center and starts

electric block

9 or 10 and carry out tuningout.

Description of drawings

Fig. 1 is the belt adjustment mechanism scheme drawing

Fig. 2 is the belt adjustment mechanism partial schematic diagram

Describe below in conjunction with accompanying drawing

Two ends, driven roller holder 11 left and right sides respectively are provided with a long waist shaped guiding circular hole, strain by bolted connection and by the

electric block

9,10 of left and right sides setting thereafter between driven cylinder 7 of belt and the driven roller holder 11 of belt, the driven cylinder 7 of belt can move forward and backward along the belt direction in the driven roller holder 11 long waist shapeds guiding of belt circular hole, belt left and right sides correspondence respectively is provided with a pair of

mechanorecepter

3,5 and time-

delay slug relay

4,6, directly over driven cylinder 7 backs monitoring device 8 is set.

The invention solves common utilization and carry out manually that on-the-spot tuningout is taken a lot of work, time-consuming limitation, reduced working strength of workers, the sideslip that belt is taken place in operational process is able in time, corrects reliably, has guaranteed the belt normal operation.

The specific embodiment

The time parameter of embodiment 1

debugging mechanorecepter

3,5 and belt 2 distances and time-

delay slug relay

4,6, when deviation phenomenon appears left in belt, behind the belt 2 contact left side mechanorecepters 5, slug relay 6 provides signal and makes left side electric block 10 tightening belt cylinders 7 left ends, makes the belt of sideslip move right normal until automatic recovery gradually; When deviation phenomenon appearred to the right in belt 2, behind the belt 2 contact right side mechanorecepters 3, slug relay 4 provided signal and makes right side electric block 9 tightening belt cylinders 7 right-hand members, makes the belt 2 of sideslip be moved to the left until automatic recovery normal gradually.

Embodiment 2 observes belt 2 sideslips by monitoring device 8 and

slug relay

4,6 when not providing signal, starts the source switch of the

electric block

9,10 that is located at control cabin, carries out tuningout.
