DE19605949A1 - Winch for winding cable or hose for robot vehicle servicing underground drains - Google Patents

Abstract

The winch is dimensioned so that it may be lowered by crane from a transporting platform into the access shaft of a street drain system, and is able to reel up or unwind a support cable or hose assembly to a robotic inspection and cleansing vehicle travelling along the drain. The drain channel (6) is inspected and cleansed by a robot (7) to which cables or hoses (8) are attached and may be wound on a drum (9) of the winch unit (1) which is positioned in the access shaft (3). The drum is rotated by a motor (10) and the cable or hose is directed on to the drum through an angle conversion unit (5). Both drum and angle drive are rotated by chains (11).

Description

The invention relates to a manhole reel with which a a sewer robot coupled cable and / or tube well del in a channel to be inspected or again is recorded.

So far, there are specially equipped vehicles for this such loading reel or platform such a reel is mounted. To The vehicle drives inspection and refurbishment work directly to the manhole and lowers it on the cable and hose bundle of connected sewer robots in the shaft. The robo ter is then inserted into the channel and the cable and Hose bundle at the transition from the shaft to the channel via a Deflection device deflected.

During the work on the shaft or canal the vehicle at the shaft and blocks the road in the immediate possible environment.

This problem leads to the task of the invention The reason is namely inspections and renovation of sewers perform that the canal environment or environment of the Revisi onsschachts not during the entire working time for the Traffic must be blocked.

The task is accomplished by a manhole reel according to the characteristics of claim 1 solved.

The manhole reel according to the invention is on a suitable one Vehicle, a platform truck, transportable and can be used lowered an on-board crane on the vehicle into the inspection shaft and be pulled up from it. The manhole reel hangs here via a crane coupling on the reel frame on the crane. Between Ab the shaft entrance can be closed and pulled up again be closed so that during the actual sewer work  ten, the shaft entrance area is again open to traffic can be. At most, the vehicle is on the roadside and make any hose and cable connections Drive-over boards protected, to the manhole cover and disappear in this. The monitoring of the channel section and the Ro botwork itself could thus be parked on the roadside be carried out.

Another advantage is such a retractable Manhole reel, that pulleys on the vehicle, manhole entrance and in particular 90 ° pulleys at the channel entrance are eliminated. That means a considerable saving in energy because the Flexing work on the cable and hose bundle on such rolls ent falls. At the same time, the bending stress disappears there as well as the tensile stress on the hanging part of the Cable and hose bundles are not required.

Via a frame and bracing devices with that, the manhole reel can simply be moved into immovable Clamp position on the shaft walls.

Using the single sketch shown in the drawing in Form of a section through the inspection shaft and the Ka naleingang the invention is explained in more detail below.

The manhole reel 1 is hung on the crane coupling 2 or simply the eye on the hook of the crane and lowered into the manhole 3 . Below, the manhole reel 1 is braced by means of a thread on the frame 12 against the manhole wall, in such a way that the winding device 5 sees the channel 6 unhindered. The channel robot 7 now takes at least the first straighter the channel section the connected cable and Schlauchbün del 8 without deflection by itself.

In the frame 12 of the manhole reel 1 , which just fits into shafts with a diameter of 700 mm, the drum 9 for winding and unwinding the cable and hose bundle 8 , the winding device 5 and the motor 10 , which have chains 11 or belts 11 or gears exerts the drive, housed. The drum 9 may have a top view of z. B. 490 mm × 490 mm. The motor 10 and servo motor 10 drives the drum 9 and the winding device 5, so that the Ka Bel and tube bundle 8 tung across the width of Wickeleinrich 5 always back and is guided here so that will be on the drum 9 winding next winding with unperturbed Layers set. The robust construction of the manhole reel 1 and the cable and hose bundle 8 is intended for long-term use.

From outside or from above, supply lines run under Um through a shaft intended for such operations cover through, so that sucking, rinsing, the power supply and a signal channel for remote observation of the process while driving stuff on the roadside is possible.
