Abstract
The invention relates to online adjustable exciting vibration equipment, which is applied to equipment which requires variable exciting force such as a vibration sieve, an activation feeder and the like. The equipment comprises an installation platform, a vibration exciter and servo motors, wherein the servo motors re controlled by a PLC (Programmable Logical controller) control system; two short shafts which are bilaterally symmetrical and coaxial with each other are arranged in the vibration exciter; eccentric blocks are fixed on the short shafts; the two short shafts are connected with corresponding servo motors through shaft couplings respectively; and the servo motors are fixed on the installation platform. The entire set of equipment runs stably and has low noise; an include angle can be formed between the two eccentric blocks by controlling the phase angles of two servo motor shafts; the frequency and the magnitude of the exciting force can be adjusted conveniently without halting, so that the working efficiency is greatly increased, and the requirements of different exciting forces on different occasions can be met; due to the adoption of the PLC control system, adjustment is more accurate and reliable; the vibration exciter has high internal airtightness, is flexible for disassembling and assembling, and is convenient for maintaining; and a plurality of installation and positioning ways are adopted for the vibration exciter, so that the concentricity of the two eccentric blocks is fully ensured.
Description
Technical field
The present invention relates to a kind of can online adjustment type excitational equipment, being applied to vibratory sieve, activation batcher etc. need provide in the equipment of variable exciting force.
Background technology
Vibratory equipment is widely used in coal now; Electric power; Harbour; Foundry Works; All trades and professions such as chemical plant; Meanwhile all trades and professions are to the requirement of vibratory equipment also increasingly stringent; The size of required exciting force; Frequency is variation day by day also; Nowadays use vibrating motor on the Duo Shuo vibratory equipment; Majority selects for use vibrating motor to come work on the market; And vibrating motor once can only provide the exciting force of certain value; Can not accomplish the purpose of regulating in the work; Desire is regulated the size of its exciting force; Opening the hood shell after must stopping debugs; Big or small to exciting force; Frequency is regulated extremely inconvenient in there is the equipment of demands of different the different periods; And be short of certain accuracy; Have a strong impact on operating efficiency, in the high-altitude; The adjusting of exciting force just becomes more complicated in the environment of mounting or dismounting inconvenience such as airtight.
Summary of the invention
According to above deficiency of the prior art; The technical problem that the present invention will solve is: what provide that a kind of practical, dispense with parking can conveniently regulate the exciting force size can online adjustment type excitational equipment, has greatly improved operating efficiency and can satisfy the requirement of the different exciting forces of different occasions.
The technical solution adopted for the present invention to solve the technical problems is: described can online adjustment type excitational equipment; It is characterized in that: comprise mounting platform, vibrator and the servomotor of controlling by PLC control system; Be provided with the minor axis of two left-right symmetric and coaxial line in the vibrator; Fixed eccentric block on the minor axis; Two minor axises all connect with corresponding servomotor respectively through shaft coupling, and servomotor is fixed on the mounting platform.
Through two servomotors of PLC control system control; Two servomotors respectively with vibrator in two minor axises be connected; Vibrator cooperates tight concentricity with abundant assurance two minor axises; Eccentric block on two minor axises is driven respectively by two servomotors; There is not any contact between the two; The motion mutually noninterfere; Make two eccentric blocks produce the size that angle changes exciting force through the phase angle of controlling two servo motor shafts; The big more exciting force of angle is more little; The more little exciting force of angle is big more, also can adjust electric machine frequency simultaneously and satisfy the requirement of different occasions to vibration frequency.This exciting force size that can online adjustment type excitational equipment can provide determines by the shape and the weight of two eccentric blocks.
Described vibrator housing is formed by connecting symmetrical two casings, and bearing block is assemblied in the endoporus of casing, and the bearing of installing on the minor axis in the vibrator is assemblied in the bearing block.Through the endoporus assembling with bearing block and casing, concentricity is higher.In order to guarantee that with one heart casing and bearing block adopt the seam location.
Described bearing block is provided with lubricating arrangement.
The beneficial effect that the present invention had is:
Whole group can operate steadily by online adjustment type excitational equipment; Noise is little; Can make two eccentric blocks produce angle through the phase angle of controlling two servo motor shafts; The size of regulating frequency, exciting force easily under non-stop-machine situation, thus greatly improve operating efficiency and can satisfy the requirement of the different exciting forces of different occasions; Through PLC control system, make adjusting more accurately and reliably; Vibrator inner sealing property is good, and dismounting is easy to maintenance flexibly; Vibrator adopts many places installing and locating mode, fully guarantees the concentricity of two eccentric blocks.
