〔産業上の利用分野〕
この考案は浄水場などの沈殿池の池底を走行す
る台車の往復と掻寄板の昇降とをロープを介して
池上の駆動ドラムにより行う沈殿物掻寄機に関す
る。[Detailed explanation of the invention] [Industrial application field] This invention uses a driving drum above the pond via a rope to reciprocate a cart that runs on the bottom of a sedimentation pond in a water purification plant, etc. and to raise and lower a scraping board. Regarding a sediment scraper.
従来の沈殿物掻寄機は例えば実開昭57−9302号
公報などに示されるように台車に直接連結された
前進用および後進用各２本のロープを池上に置か

いた。
As shown in Japanese Utility Model Application Publication No. 57-9302, a conventional sediment scraper uses two forward and two backward ropes that are directly connected to a truck and are pulled by a driving drum placed on a pond. It was structured like this.
しかし、このような構成では、各、ロープの伸
び率が異なるために、台車を繰り返し前進、後進
させると、左右のロープの長さに差が生じて、台
車が斜行して台車の車輪がレールから脱落し、運
転不能となる欠点があつた。 However, in such a configuration, each rope has a different elongation rate, so if the trolley is repeatedly moved forward and backward, a difference will occur in the length of the left and right ropes, causing the trolley to move diagonally and the wheels of the trolley to It had the disadvantage that it could fall off the rails and become unoperable.
この考案の目的は前記従来技術の欠点を解消

This idea involves attaching a pair of left and right sheaves to the forward and reverse sides of the truck, so that the forward rope from the drive drum returns to the drive drum through the pair of forward sheaves, and the The reversing rope is configured to be returned to the drive drum via a rear wall sheave, a pair of reverse sheaves, and a rear wall sheave.

る。 Pin 3 is attached to cart 2 running on rail 1 at the bottom of the pond.
A shaft 5 is loosely fitted onto the upper part of the scraping plate 4 whose intermediate portion is rotatably supported through the shaft 5, and a pair of forward sheave 7 and a bracket 6 fixed to both ends of the shaft 5 are respectively attached. The rear sheave 8 is rotatably supported.

れている。 One end of the forward rope 9 connects to the Ikegami drive drum 1.
It is fixed at 0A and the other end is the forward side sheave 7A, 7B.
is fixed to the drive drum 10B. The drive drums 10A and 10B are fixed on the same shaft 11.

に上昇する。 One end of the reverse side rope 12 is fixed to the Ikegami drive drum 10A, and the other end is fixed to the drive drum 10B via the rear wall sheave 13A, the reverse side sheaves 8A, 8B, and the rear wall sheave 13B. In the forward stroke, as shown in FIG. 3, the scraping board 4 touches the ground due to the tension of the forward rope 9, and in the backward stroke, it rises as shown by the two-dot chain line.
左右のロープの伸びの差は夫々前進側シーブ７

が斜行することはない。 The difference in elongation between the left and right ropes is the forward sheave 7.
A, 7B and backward sheaves 8A, 8B are balanced, and even if the left and right ropes have different elongation rates, the truck will not skew.

This invention is a sediment scraper in which the reciprocation of a trolley running on the bottom of a sedimentation basin and the raising and lowering of a scraping plate are carried out by a drive drum above the pond via a rope. Since the ropes are returned to the drive drum through a pair of sheaves attached to the trolley, it is possible to prevent the trolley from moving skewed due to the difference in the elongation rate of the left and right ropes.
