DE819987C - Socket clamp for pit lining and pit punches made of channel-shaped profiles - Google Patents

Description

In the case of the pit support frames and pit stamps, the above are Clamping parts of the overlap points an obstacle and annoying. In particular occurs this is evident in spaces that are strongly compressed by the pressure of the mountains are. Locomotives and trams bump into (production is disrupted), injuries the workforce while driving occur more often, injuries are also due to jumping off Screw parts are not uncommon.

To eliminate these disadvantages, according to the invention for expansion and Proposed stamp from channel-shaped profiles a sleeve clamp that close to the Profile and does not protrude into the driving area. Preferably used for clamping the overlap points of the multi-part frames uses a wedge, it is reliable and overloadable; however, screws and eccentrics can also be used for this. The sleeve clamp also has the advantage that it moves when the overlapping parts give way does not incline, so no additional clamping of the connection is created; premature This prevents the frame segments from bending.

The invention is shown in Figs. I to 4 of the drawing. for example shown.

Fig. I shows the connection in the view of an arch; Fig. 2 represents a section through the connection; Fig. 3 shows a connection in perspective rectilinear frame elements, as they are commonly used for pit punches, and Fig. 4 is a section of this.

In Fig. I, the frame racks are marked with i, the lower half of the socket clamp with 2 and the upper half of the sleeve with 3. The tightening wedge4 pulls when tightened Use a hammer to put both sleeve halves 2 and 3 together and thus also the arch parts i. The shoe 6 holds the arch parts together when slipping through, so that the upper Arch part cannot penetrate into the mountains. The ends of the sleeve halves are bent into loops in which the wedge 4 finds its support.

Fig. 2 is a section through Fig. I. The gutter-shaped arch parts i lie one inside the other at the point of overlap and are held by the sleeve halves 2 and 3 includes; the lower sleeve half 2 has the two loops 2 'and the upper one Socket half the loop 3 ', between the two lies the wedge 4. All parts lie close to the Streckeribogenteile i, nowhere are corners or edges in front of the can be a hindrance. The sleeve 3 can be designed as a simple hook 5, which is hung in the gutter.

Fig. 3 shows a further construction option for the socket clamp. There are straight frame elements shown, as they are common with the stamp. The upper sleeve half 3, like the lower 2, has a double wedge engagement. Of course, this shape can also be used with arched frames.

Fig. ¢ is the same section as Fig. 2, but on a larger scale shown. The inner profiles 8 are pressed from sheet metal, they have the flanged upper half chords 8 '; This embodiment offers special features for pit punches Advantages, but can also be used for bows. The flanging can also run in a straight line or have a hook shape. 7 is a friction piece for the inner profile.

The loops 2 'and 3' can also be placed around the wedge 4 and the ends are welded to the sleeve, which gives the construction a great load-bearing capacity receives.

The wedges can also be tightened using tension or pressure screws.
