Description

Loading device for mining operations When driving cross passages and straightening routes, the resulting rock must by eiri funding, z. B. trolleys, removed. For this purpose, the material lying on the sole is usually used shoveled into the trolley by hand. This work is cumbersome! And laborious, especially when high-altitude trams are used.

In order to make progress here, it has already been suggested that a loading device, e.g. B. short conveyor belt or the like; to turn on. This has also been done in place of the conveyor belts to provide such loading devices which grasp the material by means of a shovel -and then load it into the trolley. Besides being so mechanical operated blades are very uneconomical due to the low capacity work, is the entire structure of these known loading devices, be it conveyor belts or those with shovels, too tangled and too expensive, so that. are not the same have been able to introduce them into practice to a significant extent.

Attempts have therefore already been made in loading devices that work with shovels to replace the intricate drive, which works with cranks, with compressed air cylinders, such that the loading movement of the shovel by a single stroke of this piston was achieved. Nevertheless, the overall structure of such devices has been improved but not simplified, since the connection of the piston rod to the shovel is difficult and was only possible with the help of cumbersome lever linkages and also special Curved guides or an articulated displacement corresponding to the shovel angle of the cylinder became necessary.

According to the invention, a simpler and cheaper and perfect one becomes fail-safe solution for loading devices, in which a filling vessel by a single stroke of a piston is raised and coupled to loading height, thereby creating that. the piston rod of a preferably short-stroke compressed air cylinder through a rack and pinion coupled to a drive pulley for the cable pull carrying the filling vessel is.

This type of loading device characterized by the invention is very simple and made possible with a relatively small stroke of the compressed air cylinder the transport of the filling vessel filled by hand to the required loading height and its tilting movement.

Lifting cylinder including traction device and filling vessel can create a closed, Form arranged on a chassis or slide device, which by hand can be easily brought into any desired position. Because the stroke of the cylinder only be very brief needs, the device receives a low Overall length and is cheap to manufacture. The cylinder can be reversed by hand or by one of the known automatic control devices.

The device according to the invention can be used in all cases where it is, good of one. lower. Place one higher up To provide funding.

In the drawing, the subject matter of the invention is based on an exemplary embodiment shown.

On a single-axle chassis i is a short-stroke press cylinder 2 relocated, the piston rod 3 has a toothing q. o. The like. Has engaged with a crack 5 stands. As a result, the drum 6 and, with it, a traction means 7 (Rope or chain), driven.

The driver 7 'is attached to this traction means, the .an the filling vessel 8 attacks, -which runs with rollers 9 in the guide io -the inclined plane. At the inclined plane closes with the interposition of a curve piece downward sloping plane i i. In this way the filling vessel will be made out the position illustrated with solid lines into the position with dashed lines Tilted position drawn above the conveyor vagens 12 brought.

Claims (1)

PATENT CLAIM. Loading device for mining operations, in particular for loading conveyor wagons in which a filling vessel is replaced by a single one. Hub a piston is raised and tilted to loading height, characterized in that the piston rod of the preferably short-stroke compressed air cylinder (2 #) through a rack (q.) and Ritze- (5) with the drive disk (6) for the one carrying the filling vessel (8) Cable (7) is coupled.
