High-pressure water jet equipment uses extremely high-pressure water flow to cut rocks, which has the advantages of good heat dissipation and low pollution.

[0003] At present, when using high-pressure water jet equipment to cut rock slabs, especially rock slabs that have undergone long-distance transportation, they will be affected by force majeure factors and improper storage, which can easily cause the rock slabs to undergo slight deformation with the middle arching. In this way, when cutting a specific shape, the steel bars in the cutting pool cannot provide effective support for the rock slab, and the edge of the cut workpiece is easily cracked under the impact of high-pressure water flow.

[0024] like Figures 1 to 14As shown, an embodiment of the present invention provides a high-pressure water jet device for rock cutting, including a high-pressure jet mechanism 2 and a cutting pool 1. The high-pressure jet mechanism 2 is disclosed in the prior art, so it is not described in detail. The high-pressure jet mechanism 2 is used to spray high-pressure water to cut the rock plate. The cutting pool 1 is a stainless steel pool with a square structure. A hydraulic telescopic rod 3 is fixedly connected to the outer wall of one side of the cutting pool 1 near the bottom. The top of the hydraulic telescopic rod 3 is fixedly connected to a supporting plate 4. The supporting plate 4 is a square metal plate with rounded corners near one end of the hydraulic telescopic rod 3. The hydraulic telescopic rod 3 can be extended and retracted by computer control, thereby driving the supporting plate 4 to move vertically. The end of the supporting plate 4 away from the hydraulic telescopic rod 3 It is fixedly connected with a supporting column 5, which is a metal column with a square structure. The supporting column 5 will move vertically with the supporting plate 4; the supporting component is used to support the rock plate, and the supporting component is connected to the cutting pool 1 and the hydraulic telescopic rod 3 respectively. By setting the supporting component, not only can rock plates of different sizes be adapted and clamped and fixed, but also support can be provided for the rock plate during cutting, and at the same time, it can adapt to the different degrees of deformation of the rock plate caused by transportation, avoiding cracks on the edges of the cut workpiece, so that the staff no longer need to divide the large rock plate into several small rock plates first, and then cut the small rock plates into specific shapes, thereby improving the work efficiency of the staff.

[0025] In this embodiment, if Figures 1 to 5 As shown, the support assembly includes a first sliding cylinder 6 symmetrically slidably connected to the outer wall of the supporting column 5. The first sliding cylinder 6 is a hollow metal cylinder with a square structure, and the inner wall profile of the first sliding cylinder 6 is adapted to the outer wall profile of the supporting column 5, so the first sliding cylinder 6 can slide on the outer wall of the supporting column 5, wherein the first sliding cylinder 6 is provided with a first threaded hole 7 on the outer wall of the side facing the hydraulic telescopic rod 3. The first threaded hole 7 is a circular groove with a thread on the inner wall. A first threaded column 8 is screwed on the inner wall of the first threaded hole 7. The first threaded column 8 is a metal column with a thread on the outer wall. It is a cylinder, and the outer wall contour of the first threaded column 8 is adapted to the inner wall contour of the first threaded hole 7. The end of the first threaded column 8 away from the inner wall of the first sliding cylinder 6 is fixedly connected to the first rotating handle 9. The first rotating handle 9 is a metal cylinder with an anti-slip groove on the outer wall. Therefore, when the first rotating handle 9 is rotated clockwise, the first threaded column 8 will rotate synchronously and move along the inner wall of the first threaded hole 7 toward the center axis of the first sliding cylinder 6. At this time, the end of the first threaded column 8 away from the first rotating handle 9 will be pressed against the outer wall of the supporting column 5 to fix the first sliding cylinder 6.

[0026] The two first sliding cylinders 6 are fixedly connected to the outer wall near the bottom on the opposite side. The sliding column 10 is a metal cylinder with a square structure. The end of the sliding column 10 away from the first sliding cylinder 6 is open, and the outer wall of the sliding column 10 is slidably connected with the second sliding cylinder 11. The second sliding cylinder 11 is a hollow metal cylinder with a square structure, and the inner wall profile of the second sliding cylinder 11 is adapted to the outer wall profile of the sliding column 10, so the second sliding cylinder 11 can slide on the outer wall of the sliding column 10. A second threaded hole 12 is opened on the outer wall of the second sliding cylinder 11 facing the hydraulic telescopic rod 3. The second threaded hole 12 is opened on the inner wall. The second threaded column 13 is a metal cylinder with a thread on its outer wall, and the outer wall profile of the second threaded column 13 is adapted to the inner wall profile of the second threaded hole 12. The second threaded column 13 is fixedly connected to the second rotating handle 14 at one end away from the inner wall of the second sliding cylinder 11. The second rotating handle 14 is a metal cylinder with an anti-slip groove on its outer wall. Therefore, when the second rotating handle 14 is rotated clockwise, the second threaded column 13 will rotate synchronously and move along the inner wall of the second threaded hole 12 toward the center axis of the second sliding cylinder 11. At this time, the second threaded column 13 is away from the inner wall of the second sliding cylinder 11. One end of the second rotating handle 14 will abut against the outer wall of the sliding column 10 to fix the second sliding cylinder 11. A first abutment block 15 is fixedly connected to the bottom outer wall of the second sliding cylinder 11. The first abutment block 15 is a metal column with a convex structure. When the second sliding cylinder 11 slides, the first abutment block 15 will slide synchronously, and a fixed support plate 16 is fixedly connected to the outer wall of the first sliding cylinder 6 away from the hydraulic telescopic rod 3 near the top. The fixed support plate 16 is a metal plate with a square structure. The cooperation between the two fixed support plates 16 can support the rock plate. The fixed support plate 16 is fixed on the side away from the sliding column 10. It is connected to a first elastic plate 17, which is a metal plate with a C-shaped structure, and a weakening groove with an arc structure is provided on the inner wall near the middle. When the first elastic plate 17 is subjected to force, the first elastic plate 17 is deformed along its bending direction with the cooperation of the weakening groove. The end of the first elastic plate 17 away from the fixed support plate 16 is fixedly connected to a clamping plate 18, which is a metal plate with a square structure and is used to clamp and fix the rock plate. The end of the clamping plate 18 close to the first sliding cylinder 6 is fixedly connected to a first guide plate 19, which is an arc-shaped metal plate and the other end of which is open and is used to guide the rock plate.

[0027] When the staff first slides the first sliding cylinder 6 on the supporting column 5 according to the length of the rock plate, slides the first sliding cylinder 6 to the appropriate position, and then turns the first rotating handle 9 clockwise, the first threaded column 8 will rotate synchronously and move along the inner wall of the first threaded hole 7 toward the direction of the central axis of the first sliding cylinder 6. At this time, the end of the first threaded column 8 away from the first rotating handle 9 will contact the outer wall of the supporting column 5 to achieve the fixation of the first sliding cylinder 6. Then one side of the rock plate is placed on the supporting column 5, and then pushed between the fixed support plate 16 and the clamping plate 18 under the guidance of the first guide plate 19. At this time, the first elastic plate 17 is subjected to the extrusion force from the rock plate and will be deformed along its curved square. At the same time, the first elastic plate 17 will restore the deformation under the action of its own elasticity and drive the clamping plate 18 to move toward the direction of the fixed support plate 16, thereby clamping and fixing the rock plate. Then the hydraulic telescopic rod 3 is started, and the supporting plate 4 will be driven toward the hydraulic telescopic rod 3 by the hydraulic telescopic rod 3 When the cutting tool 1 is cut, the cutting tool 1 is moved to the left of the cutting tool 1 and the cutting tool 1 is moved to the right of the cutting tool 1. When the cutting tool 1 is cut, the cutting tool 1 is moved to the right of the cutting tool 1 and the cutting tool 1 is moved to the right of the cutting tool 1.

[0028] In this embodiment, if Figure 1 、 Figure 2 and Figures 6 to 14As shown, the support assembly also includes a plurality of fixed bases 20 fixedly connected to the inner wall of the bottom of the cutting pool 1, and the plurality of fixed bases 20 are distributed in a linear array, and the fixed bases 20 are metal cylinders with a square structure, and a first chamber 22 is provided on the top outer wall of the fixed base 20, and the first chamber 22 is a square trough with a convex cross section, and a second chamber 23 is provided on the top outer wall of the circular base 21, and the second chamber 23 is a cylindrical trough with a convex cross section, and a connecting groove 24 is provided on the bottom inner wall of the first chamber 22 close to the circular base 21, and the connecting groove 24 is a square trough, and the end of the connecting groove 24 away from the first chamber 22 is connected to the The second chamber 23 is connected, and a second piston plate 37 is slidably connected to the inner wall of the second chamber 23. The second piston plate 37 is a metal circular plate, and a layer of rubber is plated on the side wall of the second piston plate 37. Since the outer wall contour of the second piston plate 37 is adapted to the inner wall contour of the second chamber 23, the second piston plate 37 can perform piston motion on the inner wall of the second chamber 23, and the plated rubber layer can enhance the sealing between the second piston plate 37 and the second chamber 23. A fixing column 38 is fixedly connected to the top outer wall of the second piston plate 37. The fixing column 38 is a metal cylinder, and the end of the fixing column 38 away from the second piston plate 37 is fixedly connected to the second abutment block 40 (such as Figure 6 and Figure 7 As shown), there are several second abutment blocks 40 distributed in a linear array, wherein the second abutment block 40 located in the middle is a metal column with a convex structure; the two second abutment blocks 40 located at both ends are metal columns with an L-shaped structure, and are symmetrically distributed about the second abutment block 40 in the middle; the remaining second abutment blocks 40 are all metal columns with a Z-shaped structure, and are also symmetrically distributed about the second abutment block 40 in the middle. Since several second abutment blocks 40 are spliced ​​together according to each other's shapes, the overall outline formed by the cooperation between the several second abutment blocks 40 is a metal column with a square structure. A spring 39 is sleeved on the outer wall of the fixed column 38, and one end of the spring 39 is fixedly connected to the top outer wall of the circular base 21, and the other end of the spring 39 is fixedly connected to the bottom outer wall of the second abutment block 40. When the spring 39 is subjected to force, it will deform along the direction of its bending.

[0029] When the staff slides the second sliding cylinder 11 mentioned above along the outer wall of the sliding column 10, the first abutment block 15 is driven to move so that the first abutment block 15 is located on the vertical line of the center of the second abutment block 40, and then the second rotating handle 14 is turned clockwise, the second threaded column 13 will rotate synchronously and move along the inner wall of the second threaded hole 12 toward the central axis direction of the second sliding cylinder 11. At this time, the end of the second threaded column 13 away from the second rotating handle 14 will be pressed against the outer wall of the sliding column 10 to achieve the fixation of the second sliding cylinder 11. As the hydraulic telescopic rod 3 is started, the two first abutment blocks 15 will be driven Move toward the second abutment block 40, respectively abut against the tops of the two second abutment blocks 40 and push them toward the bottom of the cutting pool 1. At the same time, several second abutment blocks 40 located between the two second abutment blocks 40 will also move synchronously. At this time, the spring 39 will be subjected to the pressure of the second abutment block 40 and deformed along the bending direction; and the fixed column 38 will move under the drive of the second abutment block 40, pushing the second piston plate 37 to move along the inner wall of the second chamber 23 toward the bottom of the cutting pool 1. At the same time, the liquid in the second chamber 23 will flow into the first chamber 22 through the connecting groove 24 under the push of the second piston.

[0030] The inner wall of the first chamber 22 is slidably connected to a first piston plate 25, which is a metal plate with a square structure, and a layer of rubber is plated on the side wall of the first piston plate 25. Since the outer wall profile of the first piston plate 25 is adapted to the inner wall profile of the second chamber 23, the first piston plate 25 can perform piston motion on the inner wall of the first chamber 22, and the plated rubber layer can enhance the sealing between the first piston plate 25 and the first chamber 22. A square support plate is fixedly connected to the top outer wall of the first piston plate 25. 26, the square support plate 26 is a metal plate with a square structure, and the top of the square support plate 26 is fixedly connected with a support box 28, which is a metal column with a square structure, and the outer walls of the top near both sides are symmetrically provided with chamfers. The setting of the chamfers can reduce the impact of the high-pressure water flow on the top of the support box 28 when cutting the rock plate. The two sides of the bottom outer wall of the support box 28 are symmetrically fixedly connected with a second elastic plate 27, which is a metal plate with a C-shaped structure. When the second elastic plate 27 is subjected to force, it will bend along its The third cavity 29 is a groove whose inner wall contour matches the outer wall contour of the support box 28, and a square groove is opened on the top inner wall thereof and passes through the top outer wall of the support box 28. A plurality of third elastic plates 30 distributed in a linear array are fixedly connected to the inner wall of the third cavity 29 near the bottom. The third elastic plate 30 is a metal plate with an S-shaped structure. When the third elastic plate 30 is subjected to force, it will deform along the direction of its bending. The elastic plate 30 is fixedly connected to a placement plate 31 at one end away from the bottom of the first chamber 22. The placement plate 31 is a square metal plate, and the two ends of the placement plate 31 are symmetrically fixedly connected to a second guide plate 32. The guide plate is an arc-shaped metal plate. The top outer wall of the placement plate 31 abuts against a support seat 33. The support seat 33 is a metal triangular prism. The top of the support seat 33 is fixedly connected to a steel bar support plate 34. The steel bar support plate 34 is a square metal plate. The multiple steel bar support plates 34 located in each support box 28 are arranged in a row (such as Figure 12 ), one end of the steel bar support plate 34 is fixedly connected to a sliding protrusion 35, the sliding protrusion 35 is a cylindrical structure, and the other end of the steel bar support plate 34 is provided with a sliding groove 36, the sliding groove 36 is a circular structure groove, and the outer wall profile of the sliding protrusion 35 is adapted to the inner wall profile of the sliding groove 36 (such as Figure 14 ), so the sliding protrusion 35 on one of the steel bar support plates 34 can slide along the inner wall of the sliding groove 36 of another steel bar support plate 34, which makes it easy to assemble or replace this row of steel bar support plates 34.

[0031] When the liquid in the second chamber 23 flows into the first chamber 22 through the connecting groove 24, the liquid flowing into the first chamber 22 will push the first piston plate 25 to slide along the inner wall of the first chamber 22 toward the top of the fixed base 20. At this time, the square support plate 26 and the support box 28 will both displace synchronously, and the second elastic plate 27 will be subjected to the tension of the support box 28 and deform along its bending direction until the top ends of all the lifted steel bar support plates 34 hit the bottom outer wall of the rock plate. Due to the slight deformation of the rock plate during transportation due to the arching in the middle, all the steel bar support plates 34 lifted by the support box 28 will drive the placement plate 31 to move toward the bottom inner wall of the third chamber 29 by different distances when hitting the outer wall of the rock plate, so that the several third elastic plates 30 lifted following the support box 28 are subjected to different degrees of force and deformed to different degrees along their bending direction, so that the steel bar support plates 34 can adapt to rock plates with different degrees of bending.

[0032] When the steel bar support plate 34 is damaged after a long period of cutting work, the positions of the steel bar support plates 34 that are impacted are relatively consistent due to the cutting of a specific shape. At this time, a row of steel bar support plates 34 in the third chamber 29 can be pulled out, and the damaged steel bar support plates 34 can be pulled out from this row. After replacing the new steel bar support plates 34, this row of steel bar support plates 34 can be inserted along the inner wall of the third chamber 29. At this time, under the guidance of the second guide plate 32, the several support seats 33 fixedly connected to the bottom of the row of steel bar support plates 34 will slide into the top of the placement plate 31 in turn. In this process, the several third elastic plates 30 will be moved in turn along their bending directions. It deforms and then recovers its deformation under its own elasticity, driving the placement plate 31 to slide toward the top of the support box 28, and the support seat 33 will fit the inner wall of the third chamber 29 near the top under the drive of the placement plate 31, thus completing the replacement. The above structural setting can not only provide support for the rock plate during cutting, but also adapt to rock plates with different degrees of curvature, further improving the support effect of the rock plate. In addition, when the rock plate is cut, it provides a buffer for the high-pressure water flow to impact the rock plate, reducing the risk of cracks in the cut workpiece, and can also be partially replaced after the steel bar support plate 34 is destroyed by the high-pressure water flow, thereby reducing production costs.

[0033] The working principle of the technical solution provided by the present invention is as follows: When in use, the staff first slides the first sliding cylinder 6 on the supporting column 5 according to the length of the rock plate. After sliding the first sliding cylinder 6 to the appropriate position, the first rotating handle 9 is turned clockwise, and the first threaded column 8 will rotate synchronously and move along the inner wall of the first threaded hole 7 toward the center axis of the first sliding cylinder 6. At this time, the end of the first threaded column 8 away from the first rotating handle 9 will be pressed against the outer wall of the supporting column 5 to fix the first sliding cylinder 6.

[0034] Subsequently, the second sliding cylinder 11 is slid along the outer wall of the sliding column 10, driving the first abutment block 15 to move so that the first abutment block 15 is located on the vertical line of the center of the second abutment block 40. Then, the second rotating handle 14 is turned clockwise, and the second threaded column 13 will rotate synchronously and move along the inner wall of the second threaded hole 12 toward the central axis direction of the second sliding cylinder 11. At this time, the end of the second threaded column 13 away from the second rotating handle 14 will be pressed against the outer wall of the sliding column 10 to fix the second sliding cylinder 11.

[0035] Then one side of the rock plate is placed on the supporting column 5, and then pushed between the fixed support plate 16 and the clamping plate 18 under the guidance of the first guide plate 19. At this time, the first elastic plate 17 is subjected to the extrusion force from the rock plate and will deform along its bending direction; at the same time, the first elastic plate 17 will restore its deformation under the action of its own elasticity, driving the clamping plate 18 to move toward the direction of the fixed support plate 16, thereby clamping and fixing the rock plate.

[0036] Then start the hydraulic telescopic rod 3, and the supporting plate 4 will be driven by the hydraulic telescopic rod 3 to move toward the bottom direction of the hydraulic telescopic rod 3. At this time, the supporting column 5 will move synchronously with the supporting plate 4. At the same time, the first sliding cylinder 6, the sliding column 10, the second sliding cylinder 11 and the first abutment block 15 will also move synchronously with the supporting column 5, and the rock plate clamped by the fixed support plate 16 and the clamping plate 18 will also be driven and placed on the cutting pool 1. At this time, the two first abutment blocks 15 will be driven to move toward the second abutment block 40, respectively abutting the tops of the two second abutment blocks 40 and pushing them to move toward the bottom direction of the cutting pool 1. At the same time, the several second abutment blocks 40 located between the two second abutment blocks 40 will also move synchronously. At this time, the spring 39 will be affected by the second abutment block 40. The pressure of the connecting block 40 causes the deformation along the bending direction; the fixed column 38 will move under the drive of the second abutting block 40, pushing the second piston plate 37 to move along the inner wall of the second chamber 23 toward the bottom of the cutting pool 1, and at the same time, the liquid in the second chamber 23 will flow into the first chamber 22 through the connecting groove 24 under the push of the second piston, and the liquid flowing into the first chamber 22 will push the first piston plate 25 to slide along the inner wall of the first chamber 22 toward the top of the fixed base 20. At this time, the square support plate 26 and the support box 28 will both move synchronously, and the second elastic plate 27 will be subjected to the tension of the support box 28 and deform along its bending direction until the top of all the lifted steel bar support plates 34 hit the bottom outer wall of the rock plate.

[0037] Since the rock slab undergoes slight deformation with the middle arching during transportation, all the steel bar support plates 34 lifted by the support box 28 will drive the placement plate 31 to move toward the bottom inner wall of the third chamber 29 by different distances when they come into contact with the outer wall of the rock slab, thereby causing the several third elastic plates 30 lifted following the support box 28 to be subjected to different degrees of force and deform to different degrees along their bending direction, thereby enabling the steel bar support plates 34 to adapt to rock slabs with different degrees of bending.

[0038] When the steel bar support plate 34 is damaged after a long period of cutting, since the cutting is performed in a specific shape, the positions of the steel bar support plates 34 that are impacted are relatively consistent. At this time, a row of steel bar support plates 34 in the third chamber 29 can be pulled out, and the damaged steel bar support plates 34 can be pulled out from this row. After replacing the new steel bar support plates 34, this row of steel bar support plates 34 can be inserted along the inner wall of the third chamber 29. At this time, under the guidance of the second guide plate 32, several support seats 33 fixedly connected to the bottom of the row of steel bar support plates 34 will slide into the top of the placement plate 31 in turn. In this process, several third elastic plates 30 will deform along their bending direction in turn, and then recover their deformation under the action of their own elasticity, driving the placement plate 31 to slide toward the top of the support box 28, and the support seat 33 will be driven by the placement plate 31 to fit the inner wall of the third chamber 29 near the top, thus completing the replacement.
