Mobile two-section slope conveyor

The subject of the invention is a mobile, two-section slope conveyor designed for transporting excavated material or input in an opencast mine.

A mobile belt conveyor is known according to the German patent specification No. 2,049,613. This conveyor has three members. The first conveyor member is mounted on the bridge resting on the one side of the tracked undercarriage and on the other side it rests on the transfer machine. The other two conveyor sections rest on the reloading machine, and in particular on its booms. The bridge rests on the middle part of the body of the loading machine.

The disadvantage of the known mobile belt conveyor is the too small range of the feeding of the spoil, which practically comes down to the span of the bridge. At the same time, the weight of the reloading machine supporting the bridge on one side and supporting two sections of the belt conveyor is too large in relation to the obtained range of transport of the excavated material.

These disadvantages have been eliminated in the design of the conveyor according to the invention. This conveyor is characterized by the fact that the bridge on the side of the reloading machine rests on the boom of the reloading machine. The boom is made of two trusses joined at the point of connection with the bridge. The other ends are attached to the corners of the triangular body frame of the loading machine. Each corner of the triangular body frame of the loading machine is supported by a pair of tracks. The trusses are connected to each other and to the bridge via an angular cantilever, one side of which connects the trusses, and the bridge is suspended from the other. The bracket is suspended from the tower resting on the body. The tower is made of two frames joined together at the top and spaced at the bottom. The boom of the transfer machine has the drive of the receiving conveyor attached.

The conveyor according to the invention makes it possible to transport the excavated material or overburden over a long distance through terrain obstacles with a significantly reduced own weight. Moreover, this transport can be performed in various vertical and horizontal planes. Obtained

155 628 this is due to the articulation of the bridge to the boom of the transfer machine. Such fastening increases the transport length of the excavated material and at the same time it is a counterweight to the opposite boom. A further effect of such fastening is the possibility of significantly extending the opposite boom, since it has a natural counterbalance in the form of the weight of the bridge and the weight of the drive of the receiving conveyor. An additional measure supporting the balancing of the booms is the use of a specially constructed tower. The use of a triangular body supported by three pairs of tracks allows for proper weight distribution and proper support. The conveyor according to the invention has only two members, and the transport range is greater than that of the three-segment passable conveyors. The reduction of the number of members reduces the number of overfills, with each overfill being associated with many technical problems.

The inventive travel conveyor is explained in more detail by means of a drawing in which Fig. 1 is a side view of the conveyor, and Fig. 2 is a top view of the conveyor.

As shown in Figs. 1 and 2, the conveyor has three pairs of tracks 1 provided with pins 2 rotatably mounted in the frame 3. The frame 3 is the lower part of the body and has the shape of a triangle with pins 3 in the corners of which. Two pairs of tracks 1 are arranged coaxially. and the third pair of tracks 1 is positioned parallel and equidistant from the other two. Due to the pivoting mounting of the pin 2 in the frame 3, the tracks 1 are able to pivot around the vertical axis of the pin 2. The rotation of the tracks 1 and their travel causes the conveyor to turn or travel. Mounted on the frame 3, in particular at its base and the triangle apex, are two tiltable frames 4 and 5 which are connected at the top to form a tower. Moreover, at the top of the triangular frame 3, a mast 6 and a longer boom 7 are mounted. The longer boom 7 is suspended by cables 8 to a tilting mast 6, and the mast 6 is connected by cables to the tower. A shorter boom made of two trusses 9 is attached to the base of the triangular frame 3. The ends of the trusses 9 are fixed at the ends of the base of the triangular frame 3, and both trusses 9 are connected by a bracket 10. A joint 11 is attached to the bracket 10 and a joint 11 is hung on the joint 11. end of the bridge 12. The other end of the bridge 12 is articulated and slidably supported on a single pair of tracks 13. Moreover, a chute 14 is attached to the bracket 10 at the end of the bridge 12, and a collecting conveyor 15 is located below it, transporting the debris along the body 3 and the longer boom 7 The bridge 12 is capable of tilting from the horizontal position and further able to move in the horizontal plane within ± 100 °.

Moreover, a single pair of caterpillars 13 can run together with the caterpillars 1 so that the entire conveyor 16 mounted on the bridge 12 can be moved. it is a counterbalance to the weight of the boom 7, so that it can be long enough without the necessity of increasing the weight of the transfer machine.
