Detailed ways

Below in conjunction with specific embodiment, the utility model is further described. It should be understood that the following examples are only used to illustrate the utility model but not to limit the scope of the utility model.

The present invention proposes an automatic transport system for transporting level lanes in a coal mining area:

1. Stepping self-moving tail-automatic transportation part of bridge transfer machine:

Example 1

Referring to Fig. 1, the stepping self-moving tail includes a traveling trolley 2, telescopic legs 3, guide rail clips 4, rollers 5, guide rails 6 and push-pull cylinders 7; the traveling trolley 2 is arranged horizontally along the belt direction Above the self-moving tail fuselage; the guide rail 6 is arranged on both sides of the tail along the belt direction; the telescopic support leg 3 inverted on the tail is provided above the guide rail; the extension of the telescopic support leg 3 The outlet end is connected with a roller 5 that can roll along the guide rail through the roller shaft; a guide rail clamp 4 is installed between the guide rail 6 and the roller 5; a push-pull oil cylinder 7 is also arranged horizontally above the guide rail 6;

The bridge-type transfer machine 1 is connected to the stepping self-moving tail through the traveling trolley 2. When the stepping self-moving tail moves through the guide rail 6, the traveling trolley 2 will pull the bridge-type transfer Machine 1 moves;

The use process is:

In the first step, the telescopic outrigger 3 is stretched out, so that the guide rail 6 touches the ground and supports the entire tail;

In the second step, the push-pull cylinder 7 works, the tail of the machine moves forward as a whole, and the tail of the machine moves forward smoothly on the guide rail 6 through the roller 5, and at the same time, the traveling trolley 2 will drive the bridge loader 1 to move forward;

In the third step, after reaching the preset position, the telescopic outrigger 3 is retracted, and the guide rail clip 4 lifts the guide rail 6 at the same time, so as not to contact the ground. At this time, the tail of the aircraft is in contact with the ground;

The fourth step is to push and pull the oil cylinder 7 to work, so that the cylinder body moves in the forward direction, and drives the guide rail 6 to move forward to prepare for the next push; repeating the above steps can realize the automation of the bridge type transfer machine 1 and the stepping self-moving tail transportation;

2. Stepping self-moving tail-automatic transportation part of the intermediate frame of the retractable belt conveyor:

Example 2

Referring to Fig. 2 and Fig. 3, the middle frame of the telescopic belt conveyor is connected to the stepping self-moving tail through a connecting rod, and the connecting rod is divided into a long rod 9 and a short rod 11; one end of the long rod 9 It is fixed at 8 places of the supporting seat of the tail, and the other end is fixed at the supporting leg 12 of the intermediate frame, and is arranged horizontally; one end of the short rod 11 is fixed on the long rod 9 with a screw 10, and the other end is also fixed on the support of the intermediate frame. The legs 12 are arranged obliquely, but the short rod is fixed above the fixed position of the long rod 9 and the middle frame;

In the middle frame of the telescopic belt conveyor, the legs 12 on both sides are connected to the 8 supporting seats on both sides of the stepping self-moving tail by the above-mentioned connecting rod;

The use process is:

The first step is to open the locking handle 15 of the intermediate frame of the telescopic belt conveyor, so that the shear piece 16 can move freely up and down in the chute 14, and prepare for the forward movement of the intermediate frame afterwards;

In the second step, the described stepping self-moving tail moves as described in Embodiment 1. When the whole tail moves forward, the long rod 9 fixed on the support base 8 is also pushed forward. At this time, the long rod 9, the short rod 11 and the intermediate frame legs 12 form a quadrilateral mechanism, which can stably push the intermediate frame forward through the rollers 13;

Refer to Figure 4, which is a schematic diagram of the overall connection of the automatic transportation system for the transportation of level lanes in the coal mine area. The connecting rod is connected to the tail, and one of the long rods 9 is connected with the support seat 8 of the tail, and the other short rod 11 is directly fixed on the long rod 9 with a screw 10 .

The utility model is in order to better improve the structure, and the structure of the utility model can also adopt the following implementation on the basis of the above-mentioned technical scheme when implementing it:

Referring to Fig. 1, the cut piece 16 is fixed on the middle frame leg 12 by a screw 17;

Referring to FIG. 3 , when the long rod 9 , the short rod 11 and the legs 12 of the middle frame form a quadrilateral structure, a gasket 18 needs to be provided at the fixing place between the short rod and the legs of the middle frame.
