Abstract
The utility model discloses an adjustable overload-protection slag eliminator, which is corollary equipment of a coal burning boiler. The utility model consists of a machine body, a planetary cycloidal pin gear reducer, a sprocket chain driven by a drive sprocket axle and arranged in the machine body and a scraper of the chain, wherein, the drive sprocket is arranged on an output shaft of the planetary cycloidal pin gear reducer; and a clutch of a driven sprocket, which is connected with the drive sprocket through a drive chain, is arranged on the drive sprocket axle. The clutch comprises a left clutch and a right clutch which are provided with a clutch tooth at the sides opposite to each other, wherein, the left clutch is fixedly connected with the driven sprocket; and the axle outside the left clutch is provided with an adjusting nut and a spring which are used for adjusting the pressing force of the clutch. When the chain gets stuck, the clutch of the utility model skids to cause a motor to depart from the drive sprocket axle, thus protecting the motor of the slag eliminator and enhancing safety.
Description
Technical field
The utility model relates to a kind of and the slag remover matching used cleaning cinder of coal-burning boiler, refers in particular to a kind of boiler slag remover with adjustable overload protecting mechanism.
Background technology
Slag remover be with the matching used cleaning boiler combustion of coal-burning boiler after the equipment of cinder.Slag remover be arranged at the boiler slag notch below, the slag remover of boiler industry employing at present adopts motor-belt pulley-decelerator transmission that operation power is provided mostly, driving the sprocket wheel chain rotates, chain is provided with the scraper plate that is used for striking off cinder, and the cinder that the shuttling movement by scraper plate will fall in the slag remover body is transported to the outside.A kind of boiler slag remover is disclosed as Chinese utility model patent 200820106492.2, it comprise slag remover body, be arranged on two driving chains in the slag remover body, be fixedly connected on two scraper plates on the chain, chain is arranged on two groups of sprocket wheels that driven by drive sprocket axle and passive sprocket shaft, the slag end of scraping of scraper plate is provided with elbow, the elbow of scraper plate and scrape between the plate body and to be arc transition.
Although above-mentioned prior art has adopted the structure of the stuck chains of some control cinders, at work owing to other former thereby make the slag remover chain stuck after, problems such as burn-down of electric motor, driving belt burn also can take place, cause inconvenience and loss to the user.
The utility model content
The utility model technical issues that need to address provide a kind of after chain is stuck can to slag remover the slag remover protected of motor.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of adjustable overload protection slag remover, comprise body, dynamic power machine, be arranged in the body by the sprocket wheel chain of drive sprocket axle drive and the scraper plate on the chain, described dynamic power machine comprises planetary cycloidal pin gear reducer, and the output shaft of planetary cycloidal pin gear reducer is provided with drive sprocket; Described drive sprocket axle is provided with clutch, clutch be provided with drive sprocket by driving chain be connected by movable sprocket.
Further improvement of the utility model is: described clutch comprises left clutch and right clutch, is fixedly connected on the left clutch by movable sprocket, and the axle in the left clutch outside is provided with adjusting nut and the spring of adjusting the clutch thrust; The face that left clutch is relative with right clutch is provided with the clutch tooth.The clutch tooth is a stepped tooth.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The utility model is when chain is stuck; clutch can skid, and motor and drive sprocket axle are broken away from, and can protect the motor of slag remover; avoided making the generation of destructive accidents such as slag remover burn-down of electric motor or the fracture of decelerator parts, increased security of products because load is excessive.The utility model adopts the chain transmission, has increased mechanically operated reliability, and operating efficiency is higher; And the utility model adopts clutch as overload protecting mechanism, and it is simple in structure, and is easy to maintenance.
Planetary cycloidal pin gear reducer of the present utility model by sprocket wheel mounted thereto, driving chain drive on the left clutch by movable sprocket, clutch relies on the thrust of spring and fits together during operate as normal, be installed in slag remover drive sprocket axle upper sprocket wheel thereby can drive, drive chain and on the scraper plate running.If slag remover runs into object such as bulk slagging scorification or other reason be stuck after, when moment of torsion surpasses the thrust of spring, have the left clutch of stepped tooth and right clutch engagement position and overcome spring pressure and begin to skid, can avoid burn-down of electric motor or other parts damages.The adjusting clamp nut can change the decrement of spring, thus the output torque that acquisition needs.
