Description

Technical Field

[0001] This utility model relates to the field of mining equipment, and more specifically to the sliding breaker installation structure of the working arm of a rock drilling rig. Background Technology

[0002] Currently, the hydraulic breakers integrated into the boom of existing rock drilling rigs are all fixedly mounted directly to the top of the sliding base plate. For example, in our earlier patent application, CN221524889U, the propulsion beam structure of an anchor bolt rig has a hydraulic breaker for anchor bolting slidably mounted on the first propulsion beam. The drawbacks of this mounting structure in practical use are: because the hydraulic breaker itself is quite long, and it is fixedly mounted on the sliding base plate, its working stroke can only be determined by the sliding base plate and cannot be adjusted; furthermore, during underground drilling operations, due to space constraints, the space at the tail of the boom cannot be fully utilized, thus limiting the operational range to some extent. Utility Model Content

[0003] To address the existing technical problems, the main objective of this utility model is to provide a sliding breaker installation structure for the working arm of a rock drilling rig. This breaker is slidably mounted on a sliding base plate, thereby ensuring that the breaker can adjust its position within a certain range so that it can pass over the tail plate and make full use of the space at the tail of the rock drilling arm.

[0004] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a sliding breaker installation structure for the working arm of a rock drilling rig includes a main beam, on which a breaker slide rail is provided, and a breaker sliding plate is slidably installed on the breaker slide rail. A first vertical plate and a second vertical plate arranged in parallel are fixed on the top of the breaker sliding plate. A sliding frame structure is slidably installed on the first vertical plate and the second vertical plate, and a breaker is fixedly installed on the sliding frame structure. A cylinder mounting seat is fixed on the top of the first vertical plate and the second vertical plate, and a hydraulic cylinder is installed on the top of the cylinder mounting seat. The piston rod of the hydraulic cylinder is fixedly connected to the ear plate on the sliding frame structure.

[0005] Preferably, a rock drill slide rail is provided on the main beam and located on the side of the breaker slide rail. A rock drill sliding plate is slidably installed on the rock drill slide rail. A rock drill is fixed on the top of the rock drill sliding plate, and a drill rod is installed at the output end of the rock drill.

[0006] Preferably, a tail plate is fixed to the tail of the breaker slide rail.

[0007] Preferably, the sliding frame structure includes parallel sliding rods, one end of which is fixed with a first mounting plate and the other end of which is fixed with a second mounting plate. A breaker hammer is fixedly installed between the first and second mounting plates. The sliding rod passes through a sliding sleeve disposed between the first and second vertical plates. An ear plate is fixed to the top of the first mounting plate.

[0008] Preferably, the two ends of the slide rod are fixedly connected to the corresponding first mounting plate and second mounting plate via end flanges.

[0009] Preferably, cylinder body lugs are symmetrically fixed on both sides of the cylinder body, and the cylinder body lugs are hinged to U-shaped lugs by pins. The U-shaped lugs are fixed to the top of the cylinder body mounting base by reinforcing plates.

[0010] The present invention has the following beneficial effects: 1. The rock breaker of this utility model is slidably mounted on the sliding base plate, thereby ensuring that the rock breaker can adjust its position within a certain range so that it can pass over the tail plate and make full use of the space at the tail of the rock drilling arm.

[0011] 2. The rock drill slide rails described above enable the rock drill to be mounted, which facilitates the advancement and movement of the rock drill during subsequent operations.

[0012] 3. The tail plate can be used to limit the tail of the rock drill.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] See Figure 1-6 The sliding hydraulic breaker mounting structure of the rock drilling rig's boom includes a main beam 1, on which a hydraulic breaker slide rail 3 is mounted. A hydraulic breaker sliding plate 7 is slidably mounted on the hydraulic breaker slide rail 3. A first vertical plate 17 and a second vertical plate 15 arranged in parallel are fixed to the top of the hydraulic breaker sliding plate 7. A sliding frame structure is slidably mounted on the first vertical plate 17 and the second vertical plate 15, and a hydraulic breaker 11 is fixedly mounted on the sliding frame structure. A cylinder mounting seat 13 is fixed to the top of the first vertical plate 17 and the second vertical plate 15, and a hydraulic cylinder 14 is mounted on the top of the cylinder mounting seat 13. The piston rod 12 of the hydraulic cylinder 14 is fixedly connected to the ear plate 10 on the sliding frame structure. This hydraulic breaker is slidably mounted on the sliding base plate, thus ensuring that the hydraulic breaker can adjust its position within a certain range, allowing it to pass over the tail plate and fully utilize the space at the tail of the rock drilling arm. With the above structure, when it is necessary to move the breaker 11 during the specific working process, on the one hand, the breaker sliding plate 7 can drive the entire breaker 11 to move along the breaker slide rail 3. On the other hand, when the breaker sliding plate 7 moves to the tail end of the breaker slide rail 3, the hydraulic cylinder 14 can drive the sliding frame structure to move along the first vertical plate 17 and the second vertical plate 15, thereby further extending the stroke of the breaker 11 so that it can pass over the tail plate 6.

[0026] Furthermore, a rock drill slide rail 2 is provided on the main beam 1 and located on the side of the breaker slide rail 3. A rock drill sliding plate 23 is slidably installed on the rock drill slide rail 2, and a rock drill 5 is fixed to the top of the rock drill sliding plate 23. A drill rod 4 is installed at the output end of the rock drill 5. The rock drill slide rail 2 enables the rock drill 5 to be mounted, thereby facilitating the advancement and movement of the rock drill 5 during subsequent operations.

[0027] Furthermore, a tail plate 6 is fixed to the tail of the breaker slide rail 3. The tail plate 6 can be used to limit the tail of the rock drill 5.

[0028] Furthermore, the sliding frame structure includes parallel sliding rods 8, one end of which is fixed to a first mounting plate 9, and the other end of which is fixed to a second mounting plate 18. A hydraulic breaker 11 is fixedly mounted between the first mounting plate 9 and the second mounting plate 18. The sliding rod 8 passes through a sliding sleeve 16 disposed between the first upright plate 17 and the second upright plate 15. An ear plate 10 is fixed to the top of the first mounting plate 9. Through the aforementioned sliding frame structure, the hydraulic breaker 11 can be slidably supported between the first upright plate 17 and the second upright plate 15, thereby ensuring that the hydraulic breaker 11 can have a certain travel distance at the top of the hydraulic breaker sliding plate 7.

[0029] Furthermore, the two ends of the slide rod 8 are respectively fixedly connected to the corresponding first mounting plate 9 and second mounting plate 18 via end flanges 22. The end flanges 22 enable reliable fixed installation of the slide rod 8, thereby reliably fixing the slide rod 8 between the first mounting plate 9 and the second mounting plate 18.

[0030] Furthermore, cylinder body lugs 19 are symmetrically fixed on both sides of the cylinder body of the hydraulic cylinder 14. The cylinder body lugs 19 are hinged to U-shaped lugs 20 via pins. The U-shaped lugs 20 are fixed to the top of the cylinder body mounting base 13 via stiffening plates 21. Through the hinged engagement between the U-shaped lugs 20 and the cylinder body lugs 19, the hydraulic cylinder 14 can be reliably mounted on the cylinder body mounting base 13, thereby enabling the hydraulic cylinder 14 to subsequently provide propulsion for the movement of the sliding frame structure.

[0031] See Figure 7 In a traditional rock drilling rig, the hydraulic breaker 11 of the boom is fixedly mounted on the hydraulic breaker sliding plate 7. However, the stroke of the hydraulic breaker sliding plate 7 is limited by the tail plate 6, which leads to a waste of the tail space C. With the structure of this utility model, after the hydraulic breaker sliding plate 7 moves into place, the hydraulic breaker 11 can be driven by the hydraulic cylinder 14 to move along the first vertical plate 17 and the second vertical plate 15, thereby further extending the stroke of the hydraulic breaker 11 so that it can pass over the tail plate 6, thus making better use of the tail space.

[0032] The working process and principle of this utility model: During operation, the rock drill moves the breaker 11 via the breaker sliding plate 7, thus performing the breaking operation. When space is insufficient, the breaker sliding plate 7 moves to the position of the tail plate 6. At this time, the hydraulic cylinder 14 is activated, which drives the piston rod 12 to extend. The piston rod 12 then drives the sliding frame structure to move along the first vertical plate 17 and the second vertical plate 15, further extending the stroke of the breaker 11 so that it passes over the tail plate 6, thereby utilizing the tail space.
