Description

Technical Field

[0001] The present invention relates to the technical field of metal ore mining, and specifically to a roadheader for metal ore mining. Background Art

[0002] A roadheader is a machine used to excavate roadways on flat ground. It is divided into ordinary machines and tunnel boring machines according to the operation object. Among them, a tunnel boring machine is a comprehensive device that performs continuous operations of mechanically breaking rocks, mucking, and supporting. According to the cutting process of the roadheader on the working surface, it is divided into full-face roadheaders and partial-face roadheaders. According to the operation method, it is divided into open-type roadheaders and shield roadheaders. Among the former, the well-known large-diameter full-face rock tunnel boring machine is a complete set of tunneling equipment that integrates excavation, support, and mucking, and is known as the "aircraft carrier" and "king of roadheaders" of construction machinery.

[0003] Metal ores generally refer to minerals from which metal elements can be extracted through smelting. Metal ores are relatively hard, and roadheaders are usually used during mining. When the roadheader is performing excavation work, the cutting motor drives the roadheader bit to rotate to cut and excavate the ore. During the excavation process, the bit will wear. When the bit is damaged, the roadheader needs to be driven out of the mine tunnel to replace the bit. Since the mine tunnel is relatively deep, it takes a lot of time for the roadheader to enter and exit the mine tunnel once, seriously affecting the progress of ore mining. Therefore, we provide a roadheader for metal ore mining. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a roadheader for metal ore mining, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A roadheader for metal ore mining, including a roadheader body. A mounting seat is fixedly installed on the top of the roadheader body. A support arm one is movably sleeved on the top of the mounting seat.

The top of the transmission chain is fixedly connected to the guide block. A bidirectional driving motor is fixedly installed on the side of the support plate, and the output shaft of the bidirectional driving motor is fixedly connected to the transmission gear.

[0009] Optionally, a clamping claw is movably sleeved at the bottom of the clamping device. The number of the clamping claws is two and they are symmetrically distributed left and right. A third hydraulic strut is sleeved on the side of the clamping device, and the bottom end of the third hydraulic strut is movably sleeved outside the clamping claw.

[0010] Optionally, a scraper plate part is fixedly installed on the front of the roadheader body, and the scraper plate part is located below the cutting part.

[0011] Optionally, a fourth hydraulic strut is installed on the side of the cutting part. The top end of the fourth hydraulic strut is movably sleeved on the side of the cutting part, and the bottom end of the fourth hydraulic strut is movably sleeved with the right end of the roadheader body.

[0014] 1. For this roadheader for metal ore mining, by pushing the first support arm to rotate and lift by the first hydraulic strut, and then pushing the second support arm to rotate and lift by the second hydraulic strut, it can improve the height of the second support arm while keeping the second support arm horizontal, which is convenient for adjusting the height of the clamping device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please refer to Figures 1 to 2, the present invention provides a technical solution: a roadheader for metal ore mining, including a roadheader body 1. A mounting seat 2 is fixedly installed on the top of the roadheader body 1. A first support arm 3 is movably sleeved on the top of the mounting seat 2. A first hydraulic strut 4 is installed on the side of the first support arm 3. The top end of the first hydraulic strut 4 is movably sleeved on the side of the first support arm 3. By pushing the first support arm 3 to rotate with the first hydraulic strut 4, the height of the left end of the first support arm 3 can be raised, thereby adjusting the height of the left end of the second support arm 5. At the same time, it can push the second support arm 5 to move to the right, so that the second support arm 5 can approach the cutting part 19. The bottom end of the first hydraulic strut 4 is movably sleeved on the top of the roadheader body 1. One end of the first support arm 3 away from the mounting seat 2 is movably sleeved with a second support arm 5. A second hydraulic strut 6 is installed on the side of the second support arm 5. The bottom end of the second hydraulic strut 6 is movably sleeved on the side of the first support arm 3. By pushing the second support arm 5 to rotate with the second hydraulic strut 6, the height inside the right end of the second support arm 5 can be raised, which is convenient for adjusting the angle of the second support arm 5 with respect to the horizontal plane, so that the second support arm 5 can be aligned with the tunneling bit 24. The top end of the second hydraulic strut 6 is movably sleeved on the side of the second support arm 5.

[0026] Please refer to Figures 3 to 4 , a telescopic moving arm 7 is clamped inside the second support arm 5. By setting the telescopic moving arm 7, the telescopic moving arm 7 can slide left and right in the second support arm 5, which is convenient for extending the length of the second support arm 5, so that the clamping device 14 can approach the tunneling bit 24 for operation. A guide block 8 is fixedly connected to the bottom of the telescopic moving arm 7. A left-right moving device is fixedly connected to the bottom of the guide block 8. The left-right moving device includes a support plate 9. The support plate 9 is fixedly connected to the bottom of the second support arm 5. A transmission gear 10 is movably sleeved inside the support plate 9. A transmission chain 11 is externally engaged with the transmission gear 10. By setting the left-right moving device, by driving the transmission gear 10 to rotate with a bidirectional drive motor 12, and then driving the transmission chain 11 to move by the transmission gear 10, the transmission chain 11 can drive the telescopic moving arm 7 to move to the right, which is convenient for the telescopic moving arm 7 to extend out from the inside of the second support arm 5. The top of the transmission chain 11 is fixedly connected to the guide block 8. A bidirectional drive motor 12 is fixedly installed on the side of the support plate 9. The output shaft of the bidirectional drive motor 12 is fixedly connected to the transmission gear 10.

[0027] Please refer to Figure 1 , Figure 5, a steering motor 13 is fixedly installed at the right end of the telescopic moving arm 7. The right end of the output shaft of the steering motor 13 is fixedly connected to a clamping device 14. By driving the clamping device 14 to rotate with the steering motor 13, the clamping device 14 can be deflected left and right, which is convenient for the clamping device 14 to place the tunneling bit 24 into one of the bit placement grooves 17 and take out a new tunneling bit 24 from the other bit placement groove 17 for replacement. The bottom of the clamping device 14 is movably sleeved with clamping claws 15. The number of clamping claws 15 is two and they are symmetrically distributed left and right. A third hydraulic strut 16 is sleeved on the side of the clamping device 14. By setting the clamping device 14 and driving the clamping claws 15 to rotate with the third hydraulic strut 16, the clamping claws 15 can be opened and closed, and the tunneling bit 24 can be clamped by the clamping claws 15, which is convenient for carrying the tunneling bit 24. The bottom end of the third hydraulic strut 16 is movably sleeved on the outside of the clamping claw 15. A bit placement groove 17 is fixedly installed at the top of the roadheader body 1.

[0028] Please refer to Figure 1 , Figure 3 , Figure 6 , a cutting part 19 is movably installed on the right side of the roadheader body 1, and a scraper plate part 18 is fixedly installed on the front of the roadheader body 1. The scraper plate part 18 is located below the cutting part 19. By setting the scraper plate part 18, the scraper plate part 18 is used to collect the cut metal ore to avoid affecting the advancement of the roadheader body 1. A fourth hydraulic strut 20 is installed on the side of the cutting part 19. The top end of the fourth hydraulic strut 20 is movably sleeved on the side of the cutting part 19, and the bottom end of the fourth hydraulic strut 20 is movably sleeved together with the right end of the roadheader body 1. A cutting motor 21 is fixedly installed at the right end of the cutting part 19. By driving the tunneling bit 24 to rotate with the cutting motor 21, the tunneling bit 24 can continuously cut and excavate the metal ore and dig the metal ore out of the formation. An installation head 22 is fixedly connected to the output shaft of the cutting motor 21. A telescopic fixing block 23 is fixedly installed inside the installation head 22. The telescopic fixing blocks 23 are symmetrically distributed about the center of the installation head 22. The piston shaft of the telescopic fixing block 23 is clamped inside the tunneling bit 24. By setting the telescopic fixing blocks 23 inside the installation head 22, the telescopic fixing blocks 23 can retract into the installation head 22 during disassembly and installation, which is convenient for quickly disassembling and installing the tunneling bit 24 and improves the replacement efficiency of the tunneling bit 24. The tunneling bit 24 is sleeved outside the installation head 22.

[0029] In summary, when the roadheader for metal ore mining is in use, the support arm 1 is rotated and lifted by the hydraulic strut 1-4, and then the support arm 2 is rotated and lifted by the hydraulic strut 2-6. While keeping the support arm 2 horizontal, the height of the support arm 2 is increased. Then, the bidirectional drive motor 12 drives the transmission gear 10 to rotate, causing the transmission chain 11 to drive the telescopic moving arm 7 to move to the right, moving the clamping device 14 to the tunneling bit 24. After that, the hydraulic strut 3-16 pushes the clamping jaw 15 to rotate inward, causing the clamping jaw 15 to clamp the tunneling bit 24. Then, the piston rod of the telescopic fixing block 23 retracts into the inside of the mounting head 22, separating the tunneling bit 24 from the mounting head 22. Then, the clamping device 14 continues to move upward and to the right to remove the tunneling bit 24. When the tunneling bit 24 is completely removed, the bidirectional drive motor 12 rotates in the reverse direction, causing the telescopic moving arm 7 to move to the left, and the clamping device 14 drives the tunneling bit 24 to move above the bit placement groove 17. Then, the hydraulic strut 1-4 and the hydraulic strut 2-6 drive the support arm 1 and the support arm 2 to move downward, placing the tunneling bit 24 into the bit placement groove 17. After that, the steering motor 13 drives the clamping device 14 to deflect, aligning the clamping device 14 with another tunneling bit 24. Then, the hydraulic strut 3-16 pushes the clamping jaw 15 to rotate, causing the clamping jaw 15 to grip another tunneling bit 24. Then, the tunneling bit 24 is moved to the mounting head 22 and sleeved onto the mounting head 22 in the same way. During the sleeving process, manual assistance is required for alignment. Finally, the piston rod of the telescopic fixing block 23 re-catches the tunneling bit 24, and that's it.
