Description

The invention relates to devices for cleaning sewer pipes using scoops, pulled through the pipe with the help of cable winches. In the proposed device, the bottom of a cylindrical scoop is a piston, moved in a scoop using a separate cable, in order to be able to throw collected sediment from a cylinder after pushing the scoop to a viewing well.

In FIG. 1 shows a vertical section of the device and a side view of an “anatol” winch installed on the surface of the earth; FIG. 2 is a front view of the cable winch.

The proposed device (Fig. 1) consists of a "3 cylindrical scoop 1, the bottom of which serves as a piston 2, moved in a cylinder with the pressure of a separate rope 3. Such a scoop device is supposed to be able to throw the collected sediment out of it after pushing it to the manhole. At the top of the scoop there are protrusions 4 to which the ropes 5 are attached to move the scoop 1 along the sewer pipe. Above each of the two manholes between which the collectors are cleaned, one cable trail is installed (Fig. 1 and 2). The latter consists of a wooden, skeleton with fortified

It has shafts 6 and 7, the shaft 6 being provided with handles 8. On the lower bars 9 of the winch frame, the bar 10 is bent at an angle, holding a fork 11, which can move nd from the vertical, as well as to the left and right, with a large block 12 the goal is to move the scoop 1 in different directions to allow seizure of sediment over the entire diameter of the sewer pipe. On the bar 13, between the winch posts 14, a small block 15 is placed, through which the rope 3 is slung, passed inside the scoop 1. The length of the ropes 5 is equal to the length of the pipe being cleaned with an increase of 4-5 m to reach the winch. Ropes 3 are taken in lengths of 5-6 m and at one end are attached to both sides of piston 2, and at the other end are connected to cable 5.

When working with the proposed device, the scoop 1 is moved with the help of ropes 5 along the sewer pipe between two observation wells, and the scoop 1 with its lower surface picks up the sediments in the pipe. The unloading of the latter from the scoop 1 by reverse movement of the handle 8 informs the ropes 3 and 5 of some slack, and the rope 3 is lowered down the well, and the rope 5 is driven into the small block 15. After this, the handles 8 begin to wind both ropes on the shaft 6 until,

; the slack of rope 3 will not be selected completely, and rope 5, due to its merging with rope 3, will move iiopiucHb 2 to the left end of scoop 1 and thereby push all precipitates collected in the scoop into the manhole. To protect the latter from being washed away with water, they are immediately covered with a special shield. Then the loop of the rope 5 is removed from the small block 15 and the scoop 1 is pulled to another viewing point, but in a new way, noj b, for this purpose, with a fork 11. When the scoop 1 is pressed into the fork 11 of the second well, the precipitation is again unloaded and .d If only one manhole is used to remove sediments, it follows at the right end of the scoop 1,

instead of the rope 5, attach the rope 3 to the piston 2, with which you can move the outrigger 4nn scoop to another place to produce a new load.

The subject matter of the invention.

A device for cleaning sewer pipes using scoops pulled through a pipe using cable winches, characterized in that the scoop is shaped like a cylinder, and its bottom is the slit 2, moved in the cylinder using a separate cable, in order to get the opportunity to throw the assembled sediment when the scoop is pulled to the manhole.
