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
But the present invention relates to a kind of on-line control type excitational equipment, being applied to vibratory sieve, activating feeder etc. need to provide in the equipment of variable exciting force.
Background technology
vibratory equipment is widely used in coal now, electric power, harbour, Foundry Works, the 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 most vibratory equipments, on market, majority selects vibrating motor to come work, and vibrating motor once can only provide the exciting force of certain value, can not accomplish the purpose of regulating in work, wish 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 are the different equipment that require the different periods, and be short of certain accuracy, have a strong impact on operating efficiency, for in the high-altitude, in the environment of the mounting or dismounting inconvenience such as airtight, the adjusting of exciting force just becomes more complicated.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: but a kind of practical, on-line control type excitational equipment of need not to stop and can conveniently regulating the exciting force size is provided, greatly improve 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: but described on-line control type excitational equipment, it is characterized in that: comprise mounting platform, vibrator and the servomotor of being controlled by the PLC control system, be provided with the minor axis of two left-right symmetry and coaxial line in vibrator, fixed eccentric block on minor axis, two minor axises all connect with corresponding servomotor respectively by shaft coupling, and servomotor is fixed on mounting platform.
Control two servomotors by the PLC control system, two servomotors are connected with two minor axises in vibrator respectively, vibrator coordinates tight concentricity with abundant assurance two minor axises, eccentric block on two minor axises is driven respectively by two servomotors, between the two without any contact, the motion mutually noninterfere, make two eccentric blocks produce the size that angle changes exciting force by the phase angle of controlling two servo motor shafts, the larger exciting force of angle is less, the less exciting force of angle is larger, and also the capable of regulating electric machine frequency satisfies different occasions to the requirement of vibration frequency simultaneously.But the exciting force size that this on-line control type excitational equipment can provide determines by shape and the weight of two eccentric blocks.
Described vibrator housing is formed by connecting by symmetrical two casings, and bearing block is assemblied in the endoporus of casing, and the bearing assemble of installing on minor axis in vibrator is in bearing block.By the endoporus assembling with bearing block and casing, concentricity is higher.Concentric in order to guarantee, casing and bearing block adopt seam to locate.
Described bearing block is provided with lubricating arrangement.
The beneficial effect that the present invention has is:
But whole group of on-line control type excitational equipment operates steadily, noise is little, can make two eccentric blocks produce angle by the phase angle of controlling two servo motor shafts, the size of regulating frequency, exciting force easily in non-stop-machine situation, thus greatly improve operating efficiency and can satisfy the requirement of the different exciting forces of different occasions; By the PLC control system, make adjusting more accurately and reliably; The vibrator inner sealing is good, and dismounting is easy to maintenance flexibly; Vibrator adopts many places that locate mode is installed, and fully guarantees the concentricity of two eccentric blocks.
