Abstract

A suction trolley (6) for extracting accumulated scrap in the case of firing snow, wherein the suction trolley is movable under the flame cutting table (1) and equipped with at least one suction nozzle (7) which opens into a suction channel (8) in that he is able to take over the disposal work for materials located under the flame cutting table. a lifting and on the floor below the flame cutting table (1) lowerable cleaning shield (11) or -rechen is arranged.

Description

The Invention is directed to a suction truck for aspirating at Gas cutting processes resulting exhaust gases and dusts and for collecting accumulating scrap in the preamble of Claim 1 specified genus.

Such a suction truck is for example from the EP-0 288 598-B the applicant known. In this known solution rails are laid under the flame cutting table, on which a chassis of such a suction box is positioned, the suction box can be synchronized with the movement of the cutting torch, ie it is automatically always at the point at which is being burned to to extract the exhaust gases and dusts and, if necessary, to catch any falling material.

It has been shown in practice that repeatedly burned metal parts fall outside the position of the suction carriage under the flame cutting table, so they have to be removed at certain intervals. For this it is partly necessary that persons under the gas cutting tables Climb to pick up or remove the metal parts there.

Here uses the invention, whose task is a suction truck so that he can arrange the disposal work for to take over the materials located in the flame cutting table be able to.

With a suction truck of the type described is this task solved according to the invention in that on the suction car a lifting and on the ground under the burning cutting table lowerable cleaning shield or -rechen is arranged.

One Such cleaning shield, which can be lowered to the ground and can be moved by means of Saugwagenantriebes, a cleaning movement so that everyone is under the table Accumulate materials in front of the cleaning shield and to the one or other front end of the flame cutting table transportable so that they can be picked up and transported there can, without a person having it, to go under the flame cutting table.

refinements The invention will become apparent from the dependent claims. there can be provided that the cleaning shield on vertical guide cylinders is arranged, which are fixed in place on the suction carriage.

expedient is the cleaning shield over at least one cable raised and lowered arranged on the suction carriage, wherein in a further embodiment It can also be provided that the suction carriage with at least two on a lifting shaft effectively attached cables equipped for lifting and lowering the cleaning plate is.

Around as smooth a surface as possible below the flame cutting table provide the invention provides in a further embodiment, that the suction car in rails hanging under the flame cutting table is arranged movable, being provided in a further embodiment is that the rails for hanging up the suction carriage on the inwardly facing upper T-legs of the flame cutting table supporting double-T-beams are provided, wherein the suction pipes are fixed on the inside of the respective T-bar.

The Rotation of the lifting shaft with the cables can be done by motor or by a manually operated crank drive.

Further Features, details and advantages of the invention will become apparent the following description and with reference to the drawing. These shows in

1 an end view of the flame cutting table with suction carriage,

2 a side view of a flame cutting table in the area of the suction carriage and in

3 an enlarged detail view in the form according to 1 ,

A general with 1 designated flame cutting table rests on outside edge double T-beams 2 depending on the inwardly facing upper T-legs 2a with a guide and track rail 3 are provided, in each of which a chassis 4 is guided with a recording device 5 for an approximately funnel-shaped suction truck 6 , which is located at the bottom of suction nozzle 7 equipped in an exhaust duct system 8th with sealing lips 9 lead. On one side of the suction car 6 this is with a pair of leadership facilities, such. B. guide cylinders 10 equipped with a cleaning plate at the ends pointing downwards 11 carry, with the cleaning shield a pair of cables 12 is provided, which has a lift shaft 13 can be wound up or unwound, depending on whether the cleaning shield 11 raised or lowered.

In 1 the left half of the figure shows the cleaning shield 11 in lowered position and the right half of the figure the cleaning shield 11 in on lifted position.

The lift shaft 13 is for example in 1 on the right side in a pillow block 14 positioned while the left side with a gear 15 equipped, the z. B. is movable by means of a hand crank drive to the cleaning shield 11 lower or raise.

Shall material that is under the flame cutting table 1 fallen, can be removed, for. B. at one end of the flame cutting table 1 the cleaning shield 11 lowered by hand, the vacuum truck is then moved to the other side of the flame cutting table, scratching all fallen under the table materials using the cleaning plate from the area below the flame cutting table 1 and conveys them to the other side of the flame cutting table, where the impurities can then be taken up and transported on.

Naturally is the described embodiment of the invention to change in many ways, without the basic idea to leave. For example, on one side of the flame cutting table a rough rake should be provided to allow coarse material from the table bottom to promote away and on the other hand a fine rake or the cleaning plate described, the raising and lowering can motor, but, as described, also by means of a hand crank drive u. like.
