/ 'Hydraulically moving expansion for mining operations,

ynyv.iicrRWffiKfi Extension frame ^^ """" '_ ff

The invention relates to a hydraulically migratory expansion for the Mine operation, preferably a trestle, whose in walking | direction one behind the other arranged punch by support and ! Connecting springs are linked together by steering knuckles are braced against each other.

A trestle is known which is connected to the conveying means via a rear device and which stands one behind the other in the walking direction. The stamps are connected to one another to form a frame via support and connecting springs and the frames are in turn connected to one another by a cross member arranged approximately in the longitudinal center, which forms a stub axle, the ends of which engage on spring leaves that connect the stamps to the horizontal (French patent Λ 352 649) . Furthermore, an extension frame consisting of four rams connected to a rear cylinder attached to the conveying means is known (German Aus »=» legeschrift 1 205 035), in which the radial connections for the punch holders of the Ab "\\ was held torsion rods are made and the stamp j * and / or the spring bars of the central body and arranged slidably locked. This design gives the trestle the required dimensional rigidity and the spring bars have such elasticity that unevenness and cracks can be overcome without damaging the trestle

is. The spring bar cross is able to give the support frame such a dimensional stiffness that on Kappenquer-; lbindings can be dispensed with and the two cap pulls can move independently of each other. If in this way also a good adaptability to the circumstances is reached in the face, however, it is not yet guaranteed that the trestle as a whole with its walking movement the conveyor maintains the desired perpendicular position to the conveyor in the event of unevenness.

It is now also known (German patent specification 1 024 910), as an expansion means, the stamp on a base plate to be arranged and these base plates to be coupled to one another by hydraulic cylinders and to one another in the resulting " hanging chain of triangular support frames every second frame, taking along the conveyor, and to let the trestles in between follow suit. In the case of such a chain, by applying the appropriate action, the Cylinders possible to extend the support brackets roughly to each other judge. The prerequisite here is that all the trestles are connected to one another by hydraulic cylinders, which would help; nism moderately high effort, since it has been shown in practice that it is sufficient if every fourth or fifth Extension frame is equipped with an advance cylinder.

It is also known (German Auslegeschrift 1 214 182), ' _t two frames that are attached to one another, each occupied by two stamps - ■ are to be connected to the conveying means via traction means, the traction means being guided to abutments of the conveying means and the conveying means itself via Advance cylinder is advanced, which are assigned to the individual stamp frame. The punch frame is then pulled forward by applying the pressure cylinder to the frame accordingly. However, such an arrangement is largely unsuitable for correcting the position in relation to the conveyor, since the two frames are brought together and can be displaced with respect to one another and practically none

Have a distance from each other = Also the frames are because of the mutual Guide not generally applicable.

Frames are known from two or more stamps, each one Stamp has its own sole plate on which it stands with its spherical cap-shaped foot and one of its feet is held shell-like surrounded stamp pot.

Siü5e sole plates are articulated by crinkled connecting springs connected with each other. On the other hand, support springs held in counter-curvature are also provided, which are in height and over brackets are also laterally adjustable connected to the stamp. Support springs and connecting springs are in the middle over against each other Stub axle braced (Daulsche interpretation font @n 1 178 813 » 1 155 4-11). Such frames have sufficient dimensional stability and are elastically adaptable to all face conditions. The steering knuckles used are usually on Return and guide devices connected. You already have the rear devices between the frames for Used advance of conveying means by connecting the coupling piece provided for connecting the external guide to the piston rod has loosened so that the piston rod could act on the conveying means. In unfavorable cases, however, a the piston rod is subjected to such stress that it bends and that when it is reconnected to the guide means Constraints occurred.

The present invention is based on the object, in particular to redesign the first-mentioned known embodiment so that the frame described as with the funding connected expansion frames can be used and these expansion frames are always held vertically in their position in relation to the conveyor can.

This is achieved according to the invention in that the axis ** On both sides of the legs the spring leaves arranged on the lying surface

towers above and its ends of the attachment of a luickzylindörs serve, the connection being pivotable in all directions, in such a way that that the back forces of the cylinders are resiliently absorbed on the support frame.

In this proposed solution results in a better adaptation of the stamp to the unevenness of the Reclining because de * has ^one rear cylinder relative to the frame a unipivot • and this unipivot capable of movement in multiple planes resiliently. In relation to previously known types of fastening, this results in much longer spring travel, in all possible planes of movement. Thus, both the frame and the rear cylinder are protected from overloads · =

In the proposed solution, according to the modular principle known frames are used. When the invention is applied to support frames, the axles known from sideboards are Leg replaced by a common kingpin, at the ends of which Vordrückzylinaer are arranged.

According to a further feature of the invention, the pistons have « the VordruckzyUnder put up a push head and act with two arranged on the conveying means, trumpet-like, recessed sleeves leading the traction means together. Because the pressure cylinders are rotatably arranged in the walking plane on the steering knuckle bridge and are connected to the conveyor via a rope or chain and are connected to each other, mobility of the connection in all directions is guaranteed, and especially with different pressurization of the advance cylinder the ge * desired direction given. If the piston rod is in the same position, the removal is always at right angles to the conveyor, so that the task at hand is thus solved.

In addition, there are also advantages in terms of dimensional stiffness. Since the connection of the steering knuckle bridge with the Frame is made by wedges, it is possible to create special bumps »

to take account of the reclining position, for example, because one frame is a height difference to the other auxwo. Farther The well-known advantages of the independent mobility of the punch and die bearing plates as well as the reset the stamp in the right bank position is used by the support springs.

Furthermore, the rear stamps of the expansion can have a common * sams Yer-satzkappe have, the tongue-like between the aspens the front punch engages, so that the canopy is almost closed and great security and adaptability having.
