DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings.
[0032] Refer to Figure 1, the end frame of a self - moving tail for a tunneling face of the present utility model includes assembly 1. Fixed frames 2 are fixedly connected to both the front and rear ends of assembly 1. A second hydraulic cylinder 11 is fixedly connected to the bottom of fixed frame 2, and the output end of the second hydraulic cylinder 11 is fixedly connected to a track 10. The pulleys 15 at both ends can move through the track 10. Second connecting plates 9 are fixedly connected to both the front and rear ends on the left side of the track 10, and first connecting plates 8 are fixedly connected to both the front and rear ends on the right side of the track 10. First fixing plates 3 are fixedly connected to both the front and rear ends on the left side of assembly 1, and second support plates 7 are fixedly connected to both the front and rear ends on the right side of the first fixing plates 3. Second fixing plates 5 are fixedly connected to both the front and rear ends on the right side of assembly 1, and first support plates 6 are fixedly connected to both the front and rear ends on the left side of the second fixing plates 5. A fourth bolt 28 is threadedly connected inside the second support plate 7, and a third bolt 14 is threadedly connected inside between the first connecting plates 8. A first hydraulic cylinder 4 is rotatably connected between the fourth bolt 28 and the third bolt 14. The assembly 1 is in contact with the ground. Through the telescoping of the first hydraulic cylinder 4, the track 10 moves to the left, making the track 10 contact with the pulley 15. After the first hydraulic cylinder 4 finishes telescoping, the position of the assembly 1 moves to the left. The assembly 1 is lifted by the second hydraulic cylinder 11 to enable the whole to move.
[0033] Refer to Figure 2 - Figure 5 , a disassembly component is provided at the front end of the track 10. The disassembly component includes a fixed column 19. The fixed column 19 is fixedly connected to the left side of the track 10. An installation plate 20 is fixedly connected to the left side of the fixed column 19. Installation grooves 21 are formed in the inner walls of both the front and rear ends on the left side of the installation plate 20. The installation grooves 21 are smaller at the front and larger inside. A first bolt 12 is threadedly connected inside between the second connecting plates 9, and a second bolt 13 is threadedly connected inside between the first support plates 6. By reversely installing the first hydraulic cylinder 4 through the second connecting plates 9 and the first support plates 6, the assembly 1 can move to the right. Connecting rods 17 are fixedly connected to both the front and rear ends of the output end of the second hydraulic cylinder 11, and a baffle 18 is fixedly connected to the other end of the connecting rod 17. Rotating rods 16 are fixedly connected to the inside of both the left and right sides of the baffle 18, and pulleys 15 are rotatably connected to both the front and rear ends of the outer circle of the rotating rod 16. A triangular baffle 22 is provided on the left side of the installation plate 20. A connecting disk 23 is fixedly connected to the right side of the triangular baffle 22. Installation columns 24 are fixedly connected to both the front and rear ends on the right side of the connecting disk 23. Extrusion blocks 25 are fixedly connected to the outer circles of the installation columns 24, and a spring 26 is fixedly connected to the other end of the extrusion block 25. A universal ball 27 is fixedly connected to the other end of the spring 26. By aligning the installation columns 24 with the installation grooves 21 and inserting them, since the installation grooves 21 are smaller at the front and larger inside, the spring 26 and the universal ball 27 are squeezed, causing the whole to move inward. When moving slowly and reaching the inside, due to the larger space, the universal ball 27 is limited at the neck of the installation groove 21 to install the triangular baffle 22 and prevent impurities on the track 10.
[0034] Working principle: Contact the assembly 1 with the ground, extend and retract the first hydraulic cylinder 4 to move the track 10 to the left so that the track 10 contacts the pulley 15. After the first hydraulic cylinder 4 extends and retracts, move the position of the assembly 1 to the left. Prop up the assembly 1 with the second hydraulic cylinder 11 to move the whole. Reverse-install the first hydraulic cylinder 4 with the second connecting plate 9 and the first support plate 6 so that the assembly 1 can move to the right. Align the mounting post 24 with the mounting groove 21 and insert it. The inside of the mounting groove 21 is from small to large, and the spring 26 and the universal ball 27 are squeezed to move the whole inward. When moving slowly and moving to the inside, due to the larger space, the universal ball 27 is limited at the neck of the mounting groove 21, and the triangular baffle 22 is installed to prevent impurities in the track 10.
