Description

"Frame for one or more water troughs"

The invention relates to a frame for one or more water troughs, which? Two consisting of several parts, has collapsible longitudinal spars, which are connected at their ends with transverse spars, which by means of suspensions or the like, on expansion or the like. are attachable.

In underground mining operations it is known to hang the water troughs of so-called explosion barriers in frames or after rotating the same by 90 ° to set up on this.

Rectangular tubes are used as the longitudinal spars of the frames, the cross-section of which is dimensioned so that they can be pushed into one another, to allow a certain length compensation. These longitudinal spars are firmly connected to transverse spars, which are suspended via suspensions or the like. are attached to the expansion. The disadvantage of this known frame with longitudinal spars is that this as a result their cross-section are able to absorb only comparatively small forces. Besides, it turns out to be detrimental noticeable that they cannot be monitored in their state of wear and rotting and, as a result, the danger premature damage exists.

Proceeding from this prior art, the invention is based on the object of providing a frame of the type mentioned at the beginning Kind to the effect that this, while avoiding the disadvantages mentioned above, is not only simple and quick Manner can be monitored, but also has high stability.

According to the invention this is achieved in that the crossbars or the like in their end regions. are equipped which have passage openings which are penetrated by the ends of the longitudinal spars and these are adapted in their shape. This configuration makes it possible to use so-called open profiles, which can be easily monitored with regard to their condition. In addition, these profiles have a high load capacity. As a result of the form fit of the profiles in the passage openings ase shoes or the like. these are secured against twisting so that the longitudinal spars are evenly spaced from one another over their entire length.

The shoes or the like. are formed by flat iron, so that this can be manufactured as simple stampings.

The longitudinal spars are made of steel bars, which preferably angle, U-profile or the like. having.

Longitudinal struts at their overlapping ends with one another provided aligned longitudinal slots, which are penetrated by screws, screwed onto the threaded nuts are. In this way, the longitudinal bars can be adjusted in length, and also at high Forces a certain longitudinal displacement is possible.

An embodiment of the Ex-invention is based on the drawing explained in more detail, namely shows:

Figure 1 is a view of a frame on a transverse spar with different longitudinal spar profiles,

Figure 2 is the same view with different longitudinal spar profiles,

Figure 3 is a side view of Figure 2, Figure 4 is a plan view of Figure 2 and

Figure 5 is a front view of a longitudinal spar.

1 with the longitudinal bars are designated, which consists of two collapsible Divide 2, 3 consist. The ends 4 of the parts 2, 3

the longitudinal spars 1 are connected to the transverse spars 5, which by means of the suspension 6 and corresponding fastening means 7 are set on expansion 8. The ends 4 of the longitudinal spars 1 pass through shoes 9 attached to the ends of the transverse spars 5, which are formed by flat iron, as can be seen in particular from FIG.

The shoes 9 are at the ends of the crossbars 5 through Welded.

As shown in Figures 1 and 2, the shoes can 9 have differently shaped passage openings 10, εο e.g. angled or U-shaped cross-section, where for example the angular cross-section is edgewise or can be arranged at an acute angle. It is also possible to arrange a U-profile upright or flat, possibly also rotated by 180 °.

The parts 3, 4 of the longitudinal spars 1 are at their overlapping Ends 11 with aligned longitudinal slots 12 provided, which are penetrated by screws 13 on the Threaded nuts 14 are screwed on. Through the longitudinal slots 12 in connection with the screws 13, the parts 2, 3 adjust the length of the longitudinal spars 1 to one another.
