[0002] Coal mines are areas where humans extract coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, the coal is usually extracted through tunnels excavated underground, which is called an underground coal mine. When the coal seam is very close to the surface, the coal is usually extracted directly by removing the surface soil layer, which is called an open-pit coal mine. Tunneling is the various passages drilled between the surface and the ore body. They are used for ore transportation, ventilation, drainage, pedestrian access, and various necessary preparations for the extraction of ore by metallurgical equipment. These passages are collectively referred to as roadways.

[0042] The fixing mechanism includes a hanging plate 14, a suspension chain 15 and a double anchor hanger 16. The hanging plate 14 is fixedly mounted on the top of the monorail crane track 1, and the double anchor hanger 16 is fixedly mounted on the inner top of the tunnel body 13. One end of the suspension chain 15 is movably connected to the hanging plate 14, and the other end of the suspension chain 15 is movably connected to the double anchor hanger 16. The hanging plate 14 on the top of the monorail crane track 1 and the double anchor hanger 16 on the inner top of the tunnel body 13 are connected and installed through the suspension chain 15, so that the suspension chain 15 can suspend and pull the monorail crane track 1, and the monorail crane track 1 is better connected and installed in the tunnel body 13, so that the length of the monorail crane can be increased and extended as the excavation construction progresses, so that the construction equipment can be quickly and smoothly transported to the area to be constructed for excavation operations;

[0043] The excavation mechanism includes an equipment box 4, in which a motor 9 and a slide rail 904 are fixedly installed. A threaded rod 901 is installed at the output end of the motor 9.

A fixing frame 903 is fixedly installed at the bottom of the fixing frame 903. A mounting block 7 is fixedly installed at the bottom of the mounting block 7. A hydraulic telescopic rod B701 is fixedly installed below the mounting block 7. The threaded rod 901 is driven by the motor 9 to rotate, which can drive the corresponding connecting rod 902 to move along the slide rail 904, thereby moving the corresponding mounting block 7 at the bottom to the horizontal position. In conjunction with the hydraulic telescopic rod B701 to adjust the horizontal position of the movable plate 8, the excavation operation can be carried out for a longer time without advancing the position of the equipment box 4, thereby reducing the advancing time and improving the construction rate.

[0044] A movable plate 8 is slidably installed on the top of the mounting block 7, and the top of the movable plate 8 is fixedly installed with the output end of the hydraulic telescopic rod B701.

In conjunction with the telescopic transformation of the hydraulic telescopic rod C803, the tunneling head 806 rotates around the rotation axis 802 for height adjustment. At the same time, the position of the tunneling head 806 can also be further adjusted by the telescopic transformation of the hydraulic telescopic rod D804. Thus, the horizontal front-back adjustment and height adjustment of the tunneling head 806 can be carried out multiple times, thereby increasing the flexibility of excavating the tunnel body 13.

[0045] A mounting base 6 is fixedly installed on the top of the equipment box 4, and a moving wheel B601 is rotatably installed on the side of the mounting base 6 close to the monorail hanging track 1. A guide wheel 602 is rotatably installed on the top of the mounting base 6, and the moving wheel B601 and the guide wheel 602 are in rolling contact. A hydraulic telescopic rod E11 is fixedly installed on the side of the equipment box 4 close to the power box 2, and a top block 12 is installed on the output end of the hydraulic telescopic rod E11. Through the cooperation of the moving wheel B601 and the guide wheel 602, the equipment box 4 is assisted in moving. Moreover, during the movement of the equipment box 4, the bottom of the equipment box 4 is close to the inner bottom of the tunnel body 13 and a distance is left. While ensuring the movement of the equipment box 4, the coal blocks in the construction process can also be collected and transported to the back of the equipment box 4 through the conveyor belt 5, which is convenient for subsequent transportation and construction operations.

[0046] Among them, a method for using coal tunneling equipment based on a monorail crane includes the following steps:

[0047] Step 1: Install the monorail crane track 1, connect the monorail crane track 1 to the suspension chain 15 through the top hanging plate 14, and then connect the suspension chain 15 to the double anchor hanger 16 at the top of the tunnel body 13 to complete the installation of the monorail crane track 1;

[0048] Step 2: Use external lifting equipment to lift the equipment box 4 so that the moving wheel B601 and the guide wheel 602 are docked with the monorail track 1 and installed on the outside of the monorail track 1. Then lift the power box 2 so that the moving wheel A305 and the friction wheel 202 are docked with the monorail track 1 and installed.

[0049] Step 3: Connect and install the connecting rod 10 to the hinged seats between the power box 2 and the equipment box 4 respectively, and connect and install the power box 2 and the equipment box 4;

[0050] Step 4: Start the hydraulic motor 201 to drive the friction wheel 202 to move along the monorail crane track 1, thereby pushing the equipment box 4 installed under the monorail crane track 1 to move deeper into the tunnel body 13 and transport it to the construction area. Stop the hydraulic motor 201 and use the hydraulic telescopic rod A301 to push the extrusion rod 303 to move along the limit rod 302, so that the extrusion rod 303 drives the corresponding brake pad 304 to squeeze the monorail crane track 1 for braking and positioning, so that the power box 2 stops and stabilizes.

[0051] Step 5: The hydraulic telescopic rod E11 drives the top block 12 to squeeze the left and right inner sides of the tunnel body 13, so that the equipment box 4 can stop and stabilize to prevent the equipment box 4 from shaking. The motor 9 is started to drive the threaded rod 901 to rotate and the corresponding connecting rod 902 to slide along the slide rail 904, so that the installation block 7 moves forward to the position to be constructed;

[0052] Step 6: During tunnel construction, the movable plate 8 can be adjusted horizontally and forwardly by the hydraulic telescopic rod B701 while the tunneling head 806 is in operation, so that the tunneling head 806 contacts and excavates the tunnel body 13 in front. The tunneling head 806 is rotated around the rotation axis 802 to adjust its height by coordinating with the telescopic transformation of the hydraulic telescopic rod C803. At the same time, the position of the tunneling head 806 can be further adjusted by the telescopic transformation of the hydraulic telescopic rod D804. Thus, the horizontal and forward and height adjustments of the tunneling head 806 can be made multiple times, thereby increasing the flexibility of excavating the tunnel body 13.

[0053] Step 7: The coal blocks crushed by the tunneling head 806 are transported to the back of the equipment box 4 through the conveyor belt 5 in the equipment box 4. At the same time, the extension of the hydraulic telescopic rod C803 can also drive the hydraulic telescopic rod D804 to rotate around the rotating shaft 802. The rotation of the tunneling head 806 is used to collect the coal blocks below and put them on the conveyor belt 5 for transportation, which is convenient for the subsequent forward movement excavation operation of this device.

[0054] In summary, the hydraulic telescopic rod E11 drives the top block 12 to squeeze the left and right inner sides of the tunnel body 13, so that the equipment box 4 can stop and stabilize, avoiding the shaking of the equipment box 4, and increasing the stability of 4 during the excavation construction, thereby increasing the stability of the excavation head 806 in coal mining and improving efficiency. The motor 9 drives the threaded rod 901 to rotate, which can drive the corresponding connecting rod 902 to move along the slide rail 904, so that the corresponding mounting block 7 at the bottom can be moved to a horizontal position. In conjunction with the hydraulic telescopic rod B701 to adjust the horizontal position of the movable plate 8, the excavation operation can be carried out for a longer time without pushing the position of the equipment box 4, reducing the pushing time, so that The time of excavation construction is increased and the efficiency of construction is improved. Moreover, during the operation of the excavation head 806, the movable plate 8 can be adjusted in the horizontal front and rear directions through the hydraulic telescopic rod B701, so that the excavation head 806 can contact and excavate with the tunnel body 13 in front. In conjunction with the telescopic transformation of the hydraulic telescopic rod C803, the excavation head 806 is rotated around the rotating axis 802 for height adjustment. At the same time, the position of the excavation head 806 can be further adjusted through the telescopic transformation of the hydraulic telescopic rod D804, so that the horizontal front and rear adjustments and flexible height adjustments of the excavation head 806 can be carried out multiple times, thereby increasing the excavation flexibility of the tunnel body 13, thereby improving the efficiency of coal tunnel excavation construction of this monorail crane.

A method for using a monorail crane-based coal tunneling equipment, applied to the monorail crane-based coal tunneling equipment described in claim 1, characterized in that: The following steps are involved: Step 1: Install the monorail crane track, connect the monorail crane track to the suspension chain through the top lifting plate, and then connect the suspension chain to the double anchor rods at the top of the tunnel body to complete the installation of the monorail crane track; Step 2: Use external lifting equipment to lift the equipment box so that the moving wheel B and the guide wheel are connected to the monorail track and installed on the outside of the monorail track. Then lift the power box so that the moving wheel A and the friction wheel are connected to the monorail track and installed. Step 3: Connect and install the connecting rods to the hinged seats between the power box and the equipment box respectively, and connect and install the power box and the equipment box; Step 4: Start the hydraulic motor to drive the friction wheel to move along the monorail crane track, so as to push the equipment box installed under the monorail crane track to move deeper into the tunnel body and transport it to the construction area. Stop the hydraulic motor and use the hydraulic telescopic rod A to push the extrusion rod to move along the limit rod, so that the extrusion rod drives the corresponding brake pad to squeeze the monorail crane track for brake positioning, so that the power box stops stably; Step 5: Use the hydraulic telescopic rod E to drive the top block to squeeze the left and right inner sides of the tunnel body, so that the equipment box can stop and stabilize to prevent the equipment box from shaking. Start the motor to drive the threaded rod to rotate and drive the corresponding connecting rod to slide along the slide rail to move the installation block forward to the position to be constructed; Step 6: During tunnel construction, the movable plate is adjusted horizontally and forwardly by means of the hydraulic telescopic rod B during the operation of the tunneling head, so that the tunneling head contacts and excavates the tunnel body in front. The tunneling head is rotated around the rotation axis to adjust its height by means of the telescopic transformation of the hydraulic telescopic rod C. The position of the tunneling head can also be further adjusted by means of the telescopic transformation of the hydraulic telescopic rod D. This allows for multiple horizontal and forward adjustments of the tunneling head and flexible height adjustments, thereby increasing the flexibility of tunnel excavation. Step 7: The coal blocks crushed by the tunneling head are transported to the back of the equipment box through the conveyor belt in the equipment box. At the same time, the extension of the hydraulic telescopic rod C can drive the hydraulic telescopic rod D to rotate around the rotating axis, and the rotation of the tunneling head is used to collect the coal blocks below and put them on the conveyor belt for transportation, which is convenient for the subsequent forward movement excavation operation of this device.
