Abstract

The invention relates to mining machines and support complexes of a conveyor bridge. The goal is to simplify the design, reduce metal consumption and improve maintenance conditions. The support includes a two-track cart containing two caterpillars 1, each of which has a longitudinal beam 2, a frame 3 connected to the longitudinal beams 2 by ball joints 6, a vertical stand 7 and a carriage 8 fixed on the stand 7. to form a flat hinge, which provides the movement of the beam 5 in the vertical and rotation in the horizontal planes. Ball joints 6 are located above the flat hinges 4 in the same vertical plane. In operation, the tilting moment is perceived by frame 3 and beam 5, which perceives only horizontal force. When the tracks 1 tilt in opposite directions with respect to the hinges 4, the ball hinges 6 move in the cylindrical holes of the beams 2. At the same time, the beam 5 is lowered. 4 il.

Description

ig.Z

The invention relates to mining machines; to us and to complexes for open work, namely to conveyor belts.

The purpose of the invention is to simplify the design, reduce metal consumption and improve maintenance conditions.

FIG. 1 shows the support of the conveyor bridge, side view; in fig. 2 - the same plan view; in fig. 3 is a view A of FIG. one; in fig. 4 — node I in FIG. 3

The support of the conveyor bridge includes a two-track undercarriage containing two tracks 1, each of which has a longitudinal beam 2, a frame 3 connected to the longitudinal beams 2 by flat 5 hinges 4, a landing beam 5 connected to the longitudinal beams 2 by ball b, the vertical stand 7

on frame 3. The tilting moment from the friction between the bridge and the rollers of the carriage 8, wind, incline is perceived by the pair frame 3 - the tandem beam 5. Thus, the frame 3 c perceives vertical and horizontal forces, and the tandem beam 5 - only horizontal force.

When the tracks are tilted in opposite directions to the relatively flat hinges 4, the ball hinges b move in the cylindrical holes of the longitudinal beams 2, since the distance along the axes of the beams at these points increases. At the same time, the tandem beam 5 is lowered.

Invention Formula The support of the conveyor bridge comprising a two-track undercarriage containing a frame connected to the longitudinal balls of the carriage 8 fixed on this rack. Matnikova beam 5 is planted at the verti -....- " 7, forming a flat hinge, 20 caterpillars with flat hinges, the tilt beam allowing rotation of the tandem beam, connected to the frame with a flat, and with longitudinal beams of the tracks - ball joints, and a vertical rack rigidly connected with the frame Caret5 in the horizontal plane. At the same time, this hinge allows vertical movement of the tandem beam 5 relative to the vertical pillar 7. A ball joint, which is characterized in that, with the aim of the stops 6, connecting the tandem beam 5 with the longitudinal beams 2 caterpillars 1 , are located above the flat hinges 4, connecting the lower frame 3 with the longitudinal beams 2, i.e. located in the same vertical plane. The device works as follows. During operation, the vertical load from the carriage 8 through the rack 7 is transmitted design, reducing metal consumption and improving maintenance conditions, the man-made beam is connected to a vertical stand with the possibility of vertical movement and rotation in a 30 horizontal plane relative to the vertical stand, and the ball joints securing it to the longitudinal beams of the tracks are located above the flat joints of the frame beams. on the frame 3. The tilting moment from the friction between the bridge and the rollers of the carriage 8, wind, incline is perceived by the pair frame 3 - the tandem beam 5. Thus, frame 3 perceives the vertical and horizontal forces, and the drop beam 5 only the horizontal force. When the tracks are tilted in opposite directions to the relatively flat hinges 4, the ball hinges b move in the cylindrical holes of the longitudinal beams 2, since the distance along the axes of the beams at these points increases. At the same time, the tandem beam 5 is lowered. Invention Formula A support for a conveyor bridge incorporating a two-track undercarriage containing a frame connected to the longitudinal balls ....- " the caterpillars are flat hinges, the ma- chine beam connected to the frame is flat, and the longitudinal beams of the caterpillars are ball joints and the vertical rack rigidly connected to the frame from the carriage of the construction, reduced metal consumption and improved maintenance conditions, a steel frame A vertical stand with the possibility of vertical movement and rotation in the horizontal plane relative to the vertical rack, and the ball joints attaching it to the longitudinal beams of the tracks are located above the flat hinge E attaching the frame to these beams.
