Description

Technical Field

[0002] With the development of coal mine equipment technology, coal enterprises have gradually adopted mechanized mining and transportation, relying on automated and intelligent mining and transportation machinery to improve production efficiency, increase production capacity, and further improve production conditions and underground safety environment. At present, under the background of the gradual and comprehensive mechanization of coal mine production, the tight connection between coal mining, mining and transportation production and the discontinuous operation of each link have become a major problem restricting coal production efficiency.

[0003] At present, the common excavation and continuous mining technology used in underground coal mines is to use excavation machinery such as excavator-anchor integrated machine or tunneling machine to complete the excavation operation and simultaneously complete the support operation. The excavated slag (coal) is transferred to the retractable continuous belt conveyor by the belt transfer machine, and then transferred to other fixed belt conveyors by the continuous belt conveyor until it is transported out of the mine, thus completing the tunnel excavation and transportation of slag (coal). Among them, in order to ensure the continuity of tunnel excavation and transportation of slag (coal), while the excavation operation of the excavation machinery continues to move forward, the transportation equipment behind it must follow and move forward synchronously to ensure efficient operation.

[0004] In the process of the transport machinery following the anchor and digging machine moving forward, the continuous belt conveyor needs to extend and follow continuously. However, in the actual production process, due to safety production requirements, the machine needs to be shut down during the extension process, which reduces the start-up rate and seriously affects production efficiency.

[0036] As shown in the figure, the first protective support 3 may include a first frame 3-1, a second hanging roller group 3-2, a first upper protective plate 3-3, a lower protective plate 3-4, and a hanging plate 3-5. Figure 5. The first frame 3-1 constitutes the main frame of the first protective support 3, and the second hanging roller group 3-2 is installed through the hanging plate 3-5, and forms an inclined transition to the buffer transition device 1.

[0042] As shown in the figure, the roller group 5 includes a first roller 5-1, a second roller 5-2, a third roller 5-3, and a fourth roller 5-4. The redirection roller group 5 is used to lift the return section of the conveyor belt, so that the return section of the conveyor belt passes through the second operation protection space of the second protection bracket, and returns to the lower flat roller of the standard section fuselage at the first protection bracket, providing a corresponding operation protection space for the protection bracket.

[0043] As can be seen from the figure, the first roller 5-1 is located at the tail end of the first protective bracket 3, the second roller 5-2 is located at the front end of the second protective bracket 4, the third roller 5-3 is located at the tail end of the second protective bracket 4, and the fourth roller 5-4 is located at the towing guide rail group.

[0048] Fig.11 This is a flow chart for the standard fuselage extension installation. Fig.11 , the workflow of the standard fuselage extension installation operation is described in detail below.

[0049] The extended installation protective device for continuous belt conveyor is located at the tail of the continuous belt conveyor as a whole. The tail redirecting roller of the conveyor is shared with the self-moving tail roller. After the tail conveyor belt is redirected by the self-moving tail roller, the bearing section of the tail conveyor belt is gradually raised through the bearing roller group 6-1 of the transition section fuselage 6, leaving operating space for the extended installation operation of the standard section fuselage 2, and then passed through the bearing roller group 4-2 of the second protective bracket 4, the first protective bracket 3, the second hanging roller group 3-2, and the buffer transition device 1 The first hanging roller group 1-2 gradually descends to the height of the standard section fuselage and transitions to the load-bearing roller group 2-4 of the standard section fuselage 2; and through the belt pressing device 10, the load-bearing section is prevented from floating when it is unloaded; the return section of the conveyor belt is lifted by the return rollers on the last section moving shoe 11 and the moving shoe group 7, the fourth roller 5-4, the third roller 5-3, the second roller 5-2, and the first roller 5-1 of the roller group 5, which also leaves operating space for the extension installation operation of the standard section fuselage 2.

[0050] The first upper protective plate 3-3, the lower protective plate 3-4 of the first protective support 3 and the second upper protective plate 4-3 and the side protective plate 4-4 of the second protective support 4 can isolate the conveyor belt of the fuselage extension operation section from the personnel to ensure the safety of the personnel's operation; the extension installation protective device for the continuous belt conveyor is connected to the self-moving tail through the hinge chain 12. Whenever the excavation machinery such as the anchor drilling machine moves forward for a section, the self-moving tail of the continuous belt conveyor follows and moves forward, and drags the extension installation protective device for the continuous belt conveyor forward to follow up. Then, the operating personnel can install the standard support legs 2-1, the standard longitudinal beams 2-3, and the return roller group 2-2 in the protective space of the second protective support 4 in sequence according to the extension operation sequence, and then install the load-bearing roller group 2-4 under the protective space of the first protective support 3, thereby completing the synchronous and non-stop extension operation of the standard section of the fuselage of the tail of the continuous belt conveyor.

[0051] According to one aspect of the present invention, a continuous belt conveyor can operate synchronously with a tunneling machine without stopping, which not only ensures the safety of personnel but also greatly improves production efficiency.

[0052] Furthermore, the load-bearing section of the conveyor belt is gradually raised through the transition section of the fuselage to reserve a working height; the conveyor belt is limited by the belt pressing device, which effectively prevents the situation of belt drifting due to tension changes when the belt is unloaded, thereby improving stability; the return section of the conveyor belt redirects the belt through four rollers to raise the belt height and reserve a working height; combined with the fuselage extension installation sequence, the multiple protective plates of the protective device are used to isolate the conveyor belt and personnel in the fuselage extension working section in turn to ensure the safety of personnel operations; the lower protective plate of the first protective bracket is bent at a certain angle at one end in the direction facing the conveyor belt, and round steel is welded at both ends for a smooth transition to prevent the protective plate from scratching the belt; the dragging guide rails are hinged through pins, and the guide rails are supported by movable sliding shoes, which effectively cope with uneven ground conditions and enhance the equipment's adaptability to the complex environment of the tunnel floor.

[0053] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
