Carrier for chain conveyors

It is known as a drive means for the advancement of to use non-powered track vehicles, e.g. trolleys, endless revolving chains, so-called chain tracks, with carriers arranged one behind the other at a distance from one another on the chains, which stop on the vehicles come. It is also known that the drivers on the chain tracks not by stopping, but by friction with the possibility of slippage on the vehicle, e.g. on the vehicle axles, -to come to the attack. A well-known one Friction driver consists of a deformable under pressure and, after the load has decreased, to its original shape returning - for example, clamped in a sheet metal frame - spring body made of foamed plastic, for example Foam polyurethane. The task of the innovation is to improve a driver of this type, which you see as a disadvantage has shown that the rigidity in the spring characteristics of the spring bodies mentioned can lead to that unbelievable track vehicles as they advance through the chain conveyor to derail.

The solution to the task at hand is, according to the innovation, in the suggestion that the spring body with a or is provided several, preferably with two spaced parallel to each other cavities, and the Cavities are filled with inserts adapted to their cross-section, with - in adaptation to the respective Loading of the spring body - the material of the spring body and the inserts of different types is preferably chosen such that the first is foamed Plastic from higher and the latter from such of lower density - or vice versa - are made. This gives the possibility, depending on the operational

conditions to choose and use the spring body that their spring characteristics can be varied through a suitable choice of material in connection with the filling of the cavities in the spring body it is possible to use spring bodies made of foamed plastic as friction drivers, with these drivers if too strong forces occur, have previously determined evasive options. Bas provision of open Cavities in the spring body are prohibited because they can become clogged by dirt. The change the spring characteristics due to different external shapes are also ruled out because then possibly the specific wing loading is too great. . "" .. "'

Based on the drawing in

1 shows a longitudinal section through the driver designed according to the innovation and in _:

Fig. 2 half in section along the line II - II and half shows the same driver in view from the front side,

Let us explain the inflation as an example:

With 1 are two parallel links denotes a chain track, which are connected to one another by the axis 2. The one adjacent to the limbs subsequent chain links are denoted by 3. A base plate 4, for example a U-shaped cross-section, is attached to the links 1, on which a deformable and returning to the original shape block-like body 5 rests made of foamed plastic. From the drawing it can be clearly seen, that two cavities are provided in the spring body 5, which in the exemplary embodiment with insert bodies 5 'made of foamed plastic of lower density and lower specific gravity than that of the body itself

are filled out. From the side and from above, the block-like one becomes elastic body 5 of a shoe-like, preferably enclosed metallic hollow body, the longitudinal. Sides the reference numerals 6, the narrow sides of the reference numerals 7 and the cover surface. The reference numeral 8 "tbears. The cover surface 8 represents the Reilsrangsflache acting for the purpose of the advance on the vehicle, which as a result of the Resilience of the block-like energy storage means 5 "at ■ excessive driving resistance can slip under the attack surfaces of the vehicle and the entrainment of the Vehicle only "with a previously a" b specified driving resistance causes.
