[0028] The side wall of the second mounting plate 8 is provided with a limiting mechanism for limiting the moving direction of the hammer disc 2. The limiting mechanism includes two sliding rods 9 fixedly connected to the side wall of the second mounting plate 8. Two fixing blocks 12 are provided on the sliding rods 9. The side walls of the fixing blocks 12 are fixedly connected to the side walls of the adjacent fixing plates 4.

[0029] The side wall of the first mounting plate 5 is provided with a supporting mechanism for supporting the right fixing plate 4, and the supporting mechanism includes a bearing plate 33 slidably connected to the side wall of the first mounting plate 5, and a placement groove 32 cooperating with the fixing plate 4 is opened at the upper end of the bearing plate 33, and a plurality of mounting cylinders 18 are fixedly connected to the lower end of the bearing plate 33, and a screw 19 is provided in the mounting cylinder 18, and a locking universal wheel 20 is installed at the lower end of the screw 19.

[0030] The side wall of the first mounting plate 5 is fixedly connected with a slide rail 30, and the side wall of the supporting plate 33 is provided with a slide groove 31 that cooperates with the slide rail 30. The arrangement of the slide rail 30 and the slide groove 31 allows the supporting plate 33 to be temporarily placed near the first mounting plate 5. The screw 19 is threadedly connected to the mounting cylinder 18, so that the height of the supporting plate 33 is adjustable to cope with complex mining environments.

[0031] In the present invention, the side walls of the first mounting plate 5 and the second mounting plate 8 are fixedly connected with a plurality of first rectangular blocks 35, the side walls of the two fixing plates 4 are fixedly connected with a plurality of second rectangular blocks 37, the side walls of the first rectangular blocks 35 and the adjacent second rectangular blocks 37 are penetrated by a third bolt 34, the third bolt 34 is provided with a nut 29, the plurality of second rectangular blocks 37 of the left fixing plate 4 penetrate the side wall of the second mounting plate 8, and the plurality of second rectangular blocks 37 of the right fixing plate 4 penetrate the side wall of the first mounting plate 5.

[0032] In the present invention, a transverse plate 13 is fixedly connected to the side wall of the second mounting plate 8, a plurality of screw holes are provided at the upper end of the transverse plate 13, a connecting plate 14 is fixedly connected to the upper end of the rotating rod 24, a plurality of first bolts 15 are passed through the upper end of the connecting plate 14, and the arrangement of the transverse plate 13, the connecting plate 14 and the first bolts 15 can fix the connecting plate 14 above the transverse plate 13 when the device is transported, thereby avoiding the loss of the rotating rod 24.

[0033] In the present invention, the upper end of the placement plate 7 is fixedly connected to the limit frame 28 to prevent the driving motor 26 from shaking during transportation. A through hole is opened at the lower end of the placement plate 7, and the rotating rod 24 can pass through the through hole.

[0034] In the present invention, two connecting blocks 16 are fixedly connected to the side wall of the first mounting plate 5, and a second bolt 17 is penetrated through the side wall of the connecting block 16. A plurality of threaded holes are provided on the side walls of the first mounting plate 5 and the second mounting plate 8, and the second bolt 17 penetrates through the threaded rod 10 to further fix the threaded rod 10. The threaded rod 10 is not threadedly connected to the first mounting plate 5, but is only in a penetrating relationship.

[0035] During installation, Figure 5 For example, the first mounting plate 5 is removed from the right fixing plate 4, and openings are first made on both sides of the casing 36 (the size of the openings is the same as the specifications of the fixing plate 4), and the hammer disc 2 is placed into the casing 36 from the opening on the left side of the casing 36. The second mounting plate 8 is fixed to the left side plate of the casing 36 by bolts and nuts, and the drive motor 26 is removed. The drive cylinder 27 of the drive motor 26 is placed directly below the rotating rod 24 and fixed, and then the first mounting plate 5 is attached to the right side of the casing 36 and fixed to the side wall of the casing 36 by bolts and nuts. A plurality of third bolts 34 are passed through the adjacent first rectangular blocks 35 and second rectangular blocks 37, and then the nuts 29 are screwed in. The arrangement of the first rectangular block 35 and the second rectangular block 37 makes the connection degree of the rotor mechanism stronger, thereby improving the structural strength of the device. The transmission mechanism of the mounting shaft 1 is installed on the left side of the casing 36, so that the transmission mechanism is not required to drive the mounting shaft 1 to rotate;

[0036] Then screw in the third bolt 34 to fix the connecting block 16 and the screw rod 19, and further fix the rotor mechanism, thereby improving the connection strength between the rotor mechanism and the housing 36;

[0037] When the plate hammer 3 is damaged, the bearing plate 33 can be pulled out backwards and placed on the ground. The screw rod 19 is screwed to make the bottom height of the placement groove 32 of the bearing plate 33 the same as the height of the fixing plate 4. Then, the nuts 29 and the third bolts 34 of the first rectangular block 35 and the second rectangular block 37 on the first mounting plate 5 are screwed out, and then the nuts and bolts of the mounting frame 6 thereon are screwed out, and the first mounting plate 5 can be removed.

[0038] Then, the rotating rod 24 is removed from the horizontal plate 13 (the first bolt 15 is screwed out), and the rotating rod 24 is inserted into the rotating cylinder 25 and the driving cylinder 27, and the driving motor 26 is started. The output shaft of the driving motor 26 drives the driving cylinder 27 to rotate, and the driving cylinder 27 drives the threaded rod 10 to rotate through the engagement of the second bevel gear 23 and the first bevel gear 22. Under the limit of the two sliding rods 9, the hammer disc 2 drives the plate hammer 3 to extend from the right side of the casing 36;

[0039] After the fixing plate 4 extends out of the housing 36, the carrying plate 33 can be pushed to push the fixing plate 4 into the placement groove 32 of the carrying plate 33. After the driving motor 26 is started, the carrying plate 33 can also move to the right to support the right end of the hammer disc 2. When the plate hammer 3 on the hammer disc 2 that needs to be repaired and replaced extends out of the housing 36, the plate hammer 3 can be repaired. During the disassembly process, the right end of the hammer disc 2 is effectively supported by the carrying plate 33, so as to avoid the left side of the screw rod 19 from being easily broken due to lack of support at the right end of the heavy-mass hammer disc 2, thereby improving the rationality of the device design.

[0040] After the plate hammer 3 is repaired, the drive motor 26 (stepping motor) is started, the output shaft of the drive motor 26 is reversed, the hammer disc 2 moves leftward and resets, and then the third bolt 34 and the nut 29 are screwed into the first rectangular block 35 and the second rectangular block 37, and the second bolt 17 is screwed into the connecting block 16. During the process, the hammer disc 2 can be automatically extended out of the casing 36 without disassembling the entire casing 36. At the same time, the middle part of the hammer disc 2 that was previously difficult to repair can also be repaired, thereby improving the practicability of the device.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and practical concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
