[0044] In the embodiment, as Figure 1 、 Figure 2 and Figures 6 to 14As shown, the support assembly further comprises a plurality of fixed bases 20 fixedly connected to the inner wall of the bottom of the cutting pool 1, the plurality of fixed bases 20 are arranged in a linear array, and the fixed base 20 is a square structure metal column, a first cavity 22 is formed in the top outer wall of the fixed base 20, the first cavity 22 is a square groove with a convex cross section, a second cavity 23 is formed in the top outer wall of the circular base 21, the second cavity 23 is a cylindrical groove with a convex cross section, a connecting groove 24 is formed in the bottom inner wall of the side of the first cavity 22 close to the circular base 21, the connecting groove 24 is a square groove, and the end of the connecting groove 24 away from the first cavity 22 is in communication with the second cavity 23, a second piston plate 37 is slidably connected to the inner wall of the second cavity 23, the second piston plate 37 is a metal circular plate, and a layer of rubber is plated on the sidewall of the second piston plate 37, since the outer wall profile of the second piston plate 37 is matched with the inner wall profile of the second cavity 23, the second piston plate 37 can make piston movement on the inner wall of the second cavity 23, and the plated rubber layer can enhance the sealing between the second piston plate 37 and the second cavity 23, a fixed column 38 is fixedly connected to the top outer wall of the second piston plate 37, the fixed column 38 is a metal cylinder, and a second abutting block 40 (as shown in Figure 6 and Figure 7 ) is fixedly connected to the end of the fixed column 38 away from the second piston plate 37, the second abutting block 40 is provided in a plurality of, arranged in a linear array, wherein the second abutting block 40 located in the middle is a convex structure metal column, the two second abutting blocks 40 located at both ends are L-shaped structure metal columns, and are symmetrically distributed about the second abutting block 40 located in the middle, the remaining second abutting blocks 40 are Z-shaped structure metal columns, and are also symmetrically distributed about the second abutting block 40 located in the middle, since the plurality of second abutting blocks 40 are spliced together according to the shapes of each other, the overall profile formed by the cooperation between the plurality of second abutting blocks 40 is a square structure metal column, a spring 39 is sleeved on the outer wall of the fixed column 38, 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 abutting block 40, when the spring 39 is stressed, it will be deformed along the direction of its bending.

[0045] When the worker slides the second sliding cylinder 11 along the outer wall of the sliding column 10, the first abutting block 15 is moved to the vertical line in the center of the second abutting block 40, then the second rotating handle 14 is twisted clockwise, the second threaded column 13 is synchronously rotated, and moves along the inner wall of the second threaded hole 12 to the center 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 is tightly abutted on the outer wall of the sliding column 10, so as to realize the fixation of the second sliding cylinder 11, with the start of the hydraulic telescopic rod 3, the two first abutting blocks 15 are driven to move to the direction of the second abutting block 40, and are respectively abutted on the top of the two second abutting blocks 40 and push them to move to the bottom direction of the cutting pool 1, at the same time, the second abutting blocks 40 between the two second abutting blocks 40 are also synchronously moved, at this time the spring 39 is deformed along the bending direction under the pressure of the second abutting block 40; and the fixed column 38 is driven to move by the second abutting block 40, and pushes the second piston plate 37 to move along the inner wall of the second chamber 23 to the bottom direction of the cutting pool 1, at the same time, the liquid in the second chamber 23 is flowed into the first chamber 22 through the connecting groove 24 under the pushing of the second piston.

[0046] The inner wall of the first chamber 22 is slidably connected with a first piston plate 25, which is a square metal plate and has a rubber layer plated on the side wall. Since the outer wall contour of the first piston plate 25 is matched with the inner wall contour of the second chamber 23, the first piston plate 25 can make piston movement 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. The top outer wall of the first piston plate 25 is fixedly connected with a square support plate 26, which is a square metal plate. The top of the square support plate 26 is fixedly connected with a support box 28, which is a square metal cylinder and has symmetrical chamfers on the outer walls near the top. The chamfers can reduce the impact of high-pressure water flow on the top of the support box 28 when cutting rock plates. The bottom outer wall of the support box 28 is fixedly connected with second elastic plates 27 on both sides, which are C-shaped metal plates and will deform along the bending direction when subjected to force. The end of the support box 28 away from the circular base 21 is provided with a third chamber 29, which is a groove with an inner wall contour matched with the outer wall contour of the support box 28. A square groove is formed through the top outer wall of the support box 28. The inner wall near the bottom of the third chamber 29 is fixedly connected with third elastic plates 30 arranged in a linear array. The third elastic plates 30 are S-shaped metal plates and will deform along the bending direction when subjected to force. The end of the third elastic plate 30 away from the bottom of the first chamber 22 is fixedly connected with a placement plate 31, which is a square metal plate. The two ends of the placement plate 31 are fixedly connected with second guide plates 32, which are arc-shaped metal plates. The top outer wall of the placement plate 31 abuts against a support seat 33, which is a metal triangular prism. The top of the support seat 33 is fixedly connected with steel bar support plates 34, which are square metal plates. The steel bar support plates 34 in each support box 28 are arranged in a column (as shown in Figure 12 ). One end of the steel bar support plate 34 is fixedly connected with a sliding protrusion 35, which is a circular column. The other end of the steel bar support plate 34 is provided with a sliding groove 36, which is a circular groove. The outer wall contour of the sliding protrusion 35 is matched with the inner wall contour of the sliding groove 36 (as shown in Figure 14 ). Therefore, the sliding protrusion 35 on one steel bar support plate 34 can slide along the inner wall of the sliding groove 36 of another steel bar support plate 34, which facilitates the assembly or replacement of the column of steel bar support plates 34.

[0047] 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 pushes the first piston plate 25 to slide along the inner wall of the first chamber 22 to the top of the fixed base 20, at this time, the square support plate 26 and the support box 28 are synchronously displaced, and the second elastic plate 27 is subjected to the pulling force of the support box 28 and deformed along the bending direction thereof until the top ends of all the steel bar support plates 34 lifted by the support box 28 abut against the bottom outer wall of the rock plate, due to the slight deformation of the rock plate in the middle during transportation, when the steel bar support plates 34 lifted by the support box 28 abut against the outer wall of the rock plate, the placement plate 31 is displaced by different distances to the bottom inner wall of the third chamber 29, thereby enabling the third elastic plates 30 lifted by the support box 28 to be deformed along the bending direction thereof by different degrees, and further enabling the steel bar support plates 34 to adapt to the rock plate curved by different degrees.

[0048] When the steel bar support plate 34 is damaged after long-time cutting work, since the impact position of the steel bar support plate 34 is relatively consistent during the cutting of a specific shape, a row of steel bar support plates 34 in the third chamber 29 can be pulled out, the damaged steel bar support plate 34 is pulled out from the row, and after the replacement of the new steel bar support plate 34, the row of steel bar support plates 34 is inserted along the inner wall of the third chamber 29, at this time, under the guidance of the second guide plate 32, the support seats 33 fixedly connected to the bottom of the row of steel bar support plates 34 are sequentially slid into the top of the placement plate 31, in the process, the third elastic plates 30 are sequentially deformed along the bending direction thereof, and then restored to the deformation under the elastic action of the third elastic plates 30, thereby driving the placement plate 31 to slide to the top of the support box 28, and the support seats 33 are attached to the inner wall of the third chamber 29 close to the top under the driving of the placement plate 31, so that the replacement is completed. The above structure not only provides support for the rock plate during cutting, but also adapts to the rock plate curved by different degrees, further improves the support effect of the rock plate, and further reduces the risk of cracks of the cutting workpiece. In addition, the rock plate cutting provides a buffer for the high-pressure water flow impacting the rock plate, reduces the risk of cracks of the cutting workpiece, and can replace the steel bar support plate 34 after being hit by the high-pressure water flow, thereby reducing the production cost.

[0049] The working principle of the technical scheme provided by the present application is as follows:

[0050] In use, the staff first slides the first sliding cylinder 6 on the supporting column 5 according to the length of the rock plate, and then rotates the first rotating handle 9 clockwise after the first sliding cylinder 6 is slid to the appropriate position, so that the first threaded column 8 is synchronously rotated and moves along the inner wall of the first threaded hole 7 to the center axis direction of the first sliding cylinder 6, at this time, the end of the first threaded column 8 away from the first rotating handle 9 abuts against the outer wall of the supporting column 5 to fix the first sliding cylinder 6.

[0051] Subsequently, the second sliding cylinder 11 is slid along the outer wall of the sliding column 10, the first abutting block 15 is moved, and the first abutting block 15 is located on the vertical line at the center of the second abutting block 40. Then, the second rotating handle 14 is twisted clockwise, the second threaded column 13 is synchronously rotated, and the second threaded column 13 moves along the inner wall of the second threaded hole 12 to the center 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 abuts against the outer wall of the sliding column 10, so as to fix the second sliding cylinder 11.

[0052] Then, one side of the rock plate is placed on the supporting column 5, and then pushed into 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 deformed along the bending direction under the extrusion force from the rock plate. At the same time, the first elastic plate 17 is deformed under the elastic force of the first elastic plate 17, and the clamping plate 18 is moved to the direction of the fixed support plate 16, so as to clamp and fix the rock plate.

[0053] Subsequently, the hydraulic telescopic rod 3 is started, the supporting plate 4 is moved to the bottom of the hydraulic telescopic rod 3, and the supporting column 5 is synchronously moved with the supporting plate 4. The first sliding cylinder 6, the sliding column 10, the second sliding cylinder 11 and the first abutting block 15 are synchronously moved with the supporting column 5. The rock plate clamped and fixed by the fixed support plate 16 and the clamping plate 18 is also moved to the cutting pool 1. At this time, the two first abutting blocks 15 are moved to the direction of the second abutting block 40, and abut against the top of the two second abutting blocks 40 and push them to the bottom of the cutting pool 1. A plurality of second abutting blocks 40 between the two second abutting blocks 40 are synchronously moved. At this time, the spring 39 is deformed along the bending direction under the pressure of the second abutting block 40. The fixed column 38 is moved under the driving of the second abutting block 40, the second piston plate 37 is moved to the bottom of the cutting pool 1 along the inner wall of the second chamber 23, and the liquid in the second chamber 23 is pushed into the first chamber 22 through the connecting groove 24 under the driving of the second piston. The liquid flowing into the first chamber 22 pushes the first piston plate 25 to slide along the inner wall of the first chamber 22 to the top of the fixed base 20. At this time, the square support plate 26 and the support box 28 are synchronously displaced, and the second elastic plate 27 is deformed along the bending direction under the tension of the support box 28, until the top of all the lifted steel bar support plates 34 abuts against the bottom outer wall of the rock plate.

[0054] Due to the slight deformation of the rock plate in the middle of the arching during the transportation, the steel strip support plate 34 lifted by the support box 28 will cause the placing plate 31 to move in the direction of the inner wall of the third chamber 29 by different distances when it collides with the outer wall of the rock plate, so that the third elastic plate 30 following the support box 28 is lifted by the support box 28 is subjected to different degrees of force and deforms in the bending direction by different degrees, thereby enabling the steel strip support plate 34 to adapt to the rock plate with different degrees of bending.

[0055] When the steel strip support plate 34 is damaged after a long time of cutting work, since the cutting is of a specific shape, the position of the steel strip support plate 34 subjected to impact is relatively consistent, at this time, a row of steel strip support plates 34 in the third chamber 29 can be pulled out, the damaged steel strip support plate 34 is pulled out from this row, and after replacing the new steel strip support plate 34, the row of steel strip support plates 34 is inserted along the inner wall of the third chamber 29, at this time, under the guidance of the second guide plate 32, the support seat 33 fixedly connected to the bottom of the row of steel strip support plates 34 will be sequentially slid into the top of the placing plate 31, in this process, the third elastic plate 30 will deform in the bending direction, and then recover the deformation under the elastic action of itself, driving the placing plate 31 to slide in the direction of the top of the support box 28, and the support seat 33 will be attached to the inner wall of the third chamber 29 close to the top under the driving of the placing plate 31, so that the replacement is completed.
