Description
Technical Field
The utility model relates to a chain overspeed device tensioner, more specifically say, relate to an automatic overspeed device tensioner of mud scraper drive chain for two heavy ponds.
Background
The secondary sedimentation tank (also called secondary sedimentation tank) is used for separating mud and water, clarifying and eliminating mixed liquor, concentrating sludge and returning the separated sludge to the biological treatment section. A mud scraper is arranged in the tank, is a mud discharging device and is used for sweeping away mud settled at the bottom of the tank and skimming scum on the surface of the tank.
As shown in fig. 1, in the daily operation process of a sewage treatment plant, a secondary sedimentation tank is always in an uninterrupted operation state, all chain tensioning devices on a mud scraper are designed into a regular tensioning mode, which is unfavorable for normal operation, when a driving chain is loosened, equipment is stopped to operate, a maintenance worker is required to loosen two adjusting bolts 1 by using a wrench to adjust the two adjusting bolts to a proper tensioning force, and then the two adjusting bolts 1 are locked by using the wrench, so that regular tensioning is realized. The tensioning mode has higher technical requirements on maintenance personnel, particularly the tensioning force is adjusted by the experience of the maintenance personnel, the workload is high, the labor intensity is high, the time and the labor are wasted, the maintenance cost is high, and the sewage overflow of the corresponding service area can be caused due to the shutdown of equipment.
In conclusion, the conventional periodic tensioning method is time-consuming, poor in effect and affects operation.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect that exists among the prior art, the utility model aims at providing a mud scraper drive chain automatic tension device for two heavy ponds alleviates working strength, reduces cost of maintenance, solves the problem that relies on the manpower from the technique.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a mud scraper driving chain automatic tensioning device for a secondary sedimentation tank is characterized in that a driving chain wheel is arranged in the mud scraper, and a driving chain is wound on the driving chain wheel;
the automatic lifting device comprises a base, wherein an inclined supporting rod is connected to the base through a first pin shaft, a tensioning roller is connected to the front end of the inclined supporting rod through a second pin shaft, the tensioning roller is attached to the outer side face of a driving chain, and a heavy block is matched with the rear end of the inclined supporting rod through a heavy block base.
The tensioning roller is made of rubber.
The base, the first pin shaft, the inclined stay bar, the second pin shaft and the weight base are all made of Q235 steel.
The weight base comprises a horizontal steel plate, the front end of the horizontal steel plate is connected with the rear end of the inclined support rod, the rear end of the horizontal steel plate is vertically connected with a connecting rod, the upper end of the connecting rod is fixed on the rear end of the horizontal steel plate through a nut, and the lower end of the connecting rod is used for installing the weight.
In the technical scheme, the utility model provides a mud scraper drive chain automatic tensioning device for two heavy ponds realizes automatic straining through the complete sets such as increase dead weight body (counter weight), makes drive chain be in the tensioning state always, need not maintain, has liberated the labour, has reduced the maintenance cost, has also increased substantially the intact rate of equipment operation to whole production technology safety and orderliness's is gone on has been guaranteed.
