Description

Technical Field

[0001] The present invention relates to the technical field of water jet cutting, and in particular to a mining water jet cutting device and a use method thereof. Background Art

[0002] Water jet cutting is a plane cutting machine tool that combines an ultra-high pressure water jet generator with a two-dimensional CNC machining platform. It increases the water pressure to a high enough level (above 200MPa) so that the water has great kinetic energy and can penetrate chemical fiber, wood, leather, rubber, etc. If a certain proportion of abrasive is mixed in the high-speed water flow, it can penetrate almost all hard materials such as ceramics, stone, glass, metal, alloy, etc. Under the guidance of the two-dimensional CNC machining platform, it can start or end processing at any position of the material and move at an appropriate speed along the set trajectory to achieve plane cutting processing of any graphics. It can be used for ore cutting.

[0003] Current water jet cutting devices use high-speed water flow to cut ores. During the processing, a large amount of sewage will accumulate on the ore surface and the workbench. During the subsequent transportation and other processing steps of the cut ore, the moisture remaining on the ore surface will drip onto the processing workshop or other equipment surfaces, making the processing floor slippery, hindering the normal walking of operators and affecting the use of other processing or transportation equipment.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0044] The present invention is a mining water jet cutting device, as shown below Figures 1 to 9 Elaborate in detail.

[0045] A mining water jet cutting device comprises a body 1, a support frame slidably connected to the body 1 is arranged across the body 1, a moving platform 3 is arranged on the support frame along a direction perpendicular to the sliding direction of the support frame, a cutting head 2 is slidably arranged on the moving platform 3, and a screw feeding mechanism 4 for driving the cutting head 2 to reciprocate toward the body 1 is arranged on the moving platform 3;

The bottom surface of the moving platform 3 is provided with a bearing power mechanism for bearing the annular tube 202 and controlling the rotation of the annular tube 202;

[0047] The annular pipe 202 is connected to an air inlet pipe 204, and the air inlet pipe 204 is provided with a flexible telescopic pipe section near one end of the annular pipe 202;

[0048] A cutting groove 107 is provided on the side of the body 1 facing the cutting head 2. A cutting platform is rotatably provided in the cutting groove 107. A water leakage gap is provided on the cutting platform. A locking mechanism for locking the position of the cutting platform is provided on the body 1.

[0049] A water collecting box 5 is provided below the body 1 , and the water collecting box 5 is connected to the cutting groove 107 via a drainage pipe 6 .

[0050] The present invention provides an annular air blowing pipe, and cooperates with the movement of the support frame and the moving platform 3 to perform a completely covered drying operation on the lower cutting platform, and quickly blows the residual water on the cutting platform and the cut ore or blows it into the cutting groove 107 from the leaking gap, and the residual water on the cutting platform can be poured into the cutting groove 107 by controlling the rotation of the cutting platform, and the water flow will eventually be discharged into the water collecting tank 5. Thus, the cut ore and the sewage on the cutting platform can be quickly cleaned.

[0051] In some embodiments, the power mechanism includes a sliding seat 207 arranged on the bottom surface of the moving platform 3 for supporting the annular tube 202, and the annular tube 202 is provided with an annular slide rail 206 that is slidingly connected to the sliding seat 207. The bottom surface of the moving platform 3 is located outside the annular slide rail 206 and is slidably provided with a first telescopic power component 105. The output end of the first telescopic power component 105 is fixedly connected to the first power rack 106 along the tangential direction of the annular slide rail 206, and a driven rack 208 that meshes with the first power rack 106 is provided on the annular slide rail 206.

[0052] The sliding seat 207 is provided with a slide groove with load-bearing capacity, such as a T-shaped slide groove, an L-shaped groove, etc., and the annular slide rail 206 is provided with a slide plate of corresponding shape in cooperation with the slide groove at one end of the sliding seat 207, so that the sliding seat 207 can be slidably connected with the annular slide rail 206 while playing a load-bearing role on the annular slide rail 206, which is used to achieve the position fixation of the annular tube 202. The first telescopic power member 105 can be set as a telescopic power member with controllable stroke such as a hydraulic cylinder, an electric telescopic rod, etc. In one embodiment, the first telescopic power member 105 can also be set as a telescopic power member with a fixed stroke such as a cylinder. The first telescopic power member 105 can drive the driven rack 208 to rotate through the first power rack 106, thereby driving the annular tube 202 to rotate, so as to facilitate the air nozzle below the annular tube 202 to perform multi-angle air jet drying operations on the cut ore below.

[0053] In some embodiments, a heating chamber 201 is provided on the top wall of the mobile platform, an air inlet pipe 204 is provided through the heating chamber 201, and a heater 203 is provided around the air inlet pipe 204 in the heating chamber 201. Multiple heaters 203 in the heating chamber 201 are provided around the air inlet pipe 204, and the gas passing through this position can be heated, so that the gas has a certain temperature when it is ejected from the air nozzle, thereby quickly evaporating the ore and the residual moisture that is not easy to be separated from the surface of the cutting platform.

[0054] In some embodiments, the cutting platform includes a rotating frame 101, on which a plurality of bearing uprights 102 of equal height are arranged at equal intervals, and a water leakage gap is arranged between adjacent bearing uprights 102. The rotating frame 101 is provided with rotating shafts 103 at both ends in a direction perpendicular to the bearing uprights 102, and the rotating shafts 103 are rotatably connected to the fuselage 1, and the rotating shafts 103 on either side of the rotating frame 101 penetrate the fuselage 1 and are fixedly connected to a power gear 104, and a second telescopic power member 209 is arranged on the side wall of the fuselage 1 corresponding to the power gear 104, and the output end of the second telescopic power member 209 is fixedly connected to a second power rack 210 that meshes with the power gear 104. The setting of the rotating frame 101 can provide an overall rotating platform, thereby driving all the bearing uprights 102 to tilt and rotate along the rotation direction of the rotating shaft 103, so that most of the water remaining on the cut ore and each bearing upright 102 is poured into the bottom of the cutting groove 107. The arrangement of multiple bearing uprights 102 and water leakage gaps can form a cutting platform with a rapid water leakage and drainage function, thereby achieving rapid drainage without affecting the bearing effect on the cut ore.

[0055] In some embodiments, in order to keep the cutting platform in a horizontal state during the ore cutting process, the locking mechanism is arranged on the outer side wall of the fuselage 1 facing the second telescopic power member 209, and the locking mechanism includes a plurality of groups of positioning holes correspondingly arranged on the fuselage 1 and the rotating frame 101, and a positioning pin 301 is inserted in each group of positioning holes, and the positioning pin 301 passes through the side wall of the fuselage 1 and the side wall of the rotating frame 101; when the positioning pin 301 is inserted into the corresponding positioning hole group, the positioning pin 301 can hinder the rotation of the rotating frame 101, so that the rotating frame 101 is horizontally positioned, ensuring that the cutting platform is maintained in a horizontal state. The provision of multiple positioning pins 301 can form multiple insurance measures to prevent the rotating frame 101 from rotating again when a single positioning pin 301 is broken or detached from any one of the rotating frame 101 and the fuselage 1.

[0056] In order to facilitate the synchronous control of multiple positioning pins 301, a synchronization plate is fixedly connected to the end of the multiple positioning pins 301 away from the rotating frame 101, and a third telescopic power member 302 is arranged between the synchronization plate and the fuselage 1. The third telescopic power member 302 can be set as a power mechanism or device with telescopic function such as a cylinder, a hydraulic cylinder or an electric telescopic rod. In one embodiment, multiple groups of positioning holes are symmetrically arranged, and the third telescopic power member 302 is arranged at a symmetrical center position, the synchronization plate is arranged in a "J" shape, the output end of the third telescopic power member 302 is fixedly connected to the inner central position of the "J"-shaped synchronization plate, and multiple groups of positioning pins 301 are symmetrically arranged on the bottom wall on both sides of the "J"-shaped synchronization plate. When the output end of the third telescopic power member 302 is extended, the synchronization plate will synchronously pull all the positioning pins 301 out of the positioning hole group, so that the positioning pins 301 are separated from the rotating frame 101, so that the rotating frame 101 can rotate again.

[0057] In some embodiments, a clearance gap is provided between the rotating frame 101 and the bottom wall of the cutting groove 107, a drain plate 401 is provided in the clearance gap along the direction perpendicular to the supporting vertical plate 102, the drain plate 401 is provided perpendicularly to the bottom wall of the cutting groove 107, a driving motor 402 is provided on any side wall of the fuselage 1 parallel to the drain plate 401, the output shaft of the driving motor 402 passes through the side wall of the fuselage 1 and is fixedly connected with a screw 403, the screw 403 is perpendicular to the drain plate 401 and is threadedly connected to the drain plate 401. The setting of the clearance gap can provide a tilting space for the rotation of the rotating frame 101, and the drain plate 401 can reciprocate along the length direction of the screw 403 under the action of the driving motor 402, thereby realizing the discharge of water falling into the bottom of the cutting groove 107.

[0058] In order to further cooperate with the drainage action of the drain plate 401, the drain pipe 6 is connected and arranged on one or two of the two side walls of the body parallel to the screw 403, and there are two drain pipes 6 on each side wall. The two drain pipes 6 are symmetrically arranged at the positions of the side walls corresponding to the two ends of the screw 403. When the drain plate 401 pushes the water, due to the squeezing of the drain plate 401 and the inner wall of the cutting groove 107, the water will flow rapidly toward both sides, that is, flow toward the drain pipes 6 on both sides. The drain pipe 6 is arranged in a position such that when the drain plate 401 approaches the inner wall of the cutting groove 107 on either side, the water flow can always maintain a state of rapid flow toward the drain pipe 6, thereby accelerating the discharge of water in the cutting groove 107.

[0059] In some embodiments, a plurality of U-shaped plates 501 are arranged on the top wall of the drain plate 401 facing the side of the supporting upright plate 102, the U-shaped plates 501 are parallel to the drain plate 401, and the open end of the U-shaped plates 501 is arranged toward the side of the drain plate 401, each U-shaped plate 501 is arranged one-to-one with each water leakage gap, and the side wall of the U-shaped plate 501 is arranged to be slidably abutted against the side wall of the adjacent supporting upright plate 102. The arrangement of the U-shaped plates 501 can wipe the side wall of the supporting upright plate 102, and when the drain plate 401 moves under the action of the driving motor 402, the U-shaped plates 501 can move with the drain plate 401, thereby wiping the two side walls of each supporting upright plate 102.

[0060] In some embodiments, considering that during the process of controlling the movement of the drain plate 401, the cut ore fixed above the supporting vertical plate 102 may not have completed the cutting operation and needs to continue to be fixed on the cutting platform, at this time, the U-shaped plate 501 is required to give way when passing through the ore. Therefore, the U-shaped plate 501 is hinged to the drain plate 401, and a reset structure is provided on the drain plate 401 for the U-shaped plate 501 to restore the state of being parallel to the drain plate 401. The reset structure includes a fixed block 504 fixedly arranged at a position between the openings of the U-shaped plate 501 on the drain plate 401, and an elastic reset rod 502 is fixedly arranged between the fixed block 504 and the two side walls of the opening of the U-shaped plate 501.

[0061] Under normal conditions, the elastic reset rods 502 on both sides of the fixed block 504 pull the U-shaped plate 501 to an upright state, at which time the U-shaped plate 501 is parallel to the drain plate 401; when the U-shaped plate 501 contacts the ore, the U-shaped plate 501 will rotate and press in the direction away from the drain plate 401 under the obstruction of the ore, and the elastic reset rods 502 are stretched in the process; when the pressed U-shaped plate 501 is completely separated from the ore, the elastic reset rods 502 restore the deformation and drive the U-shaped plate 501 to return to an upright state. During the entire movement process, in order to ensure that the U-shaped plate 501 can still complete the wiping operation of the side wall of the supporting vertical plate 102 in the downward state, the height of the U-shaped plate 501 is set higher than the height of the supporting vertical plate 102, so as to avoid the situation where the U-shaped plate 501 cannot completely wipe the side wall of the supporting vertical plate 102 when it contacts the uneven surface of the ore.

[0062] In some embodiments, a water-absorbing sponge 503 is provided on the outer wall of the U-shaped plate 501 at a height corresponding to the top wall of the supporting upright plate 102, and the water-absorbing sponge 503 is arranged in contact with the top wall of the supporting upright plate 102. The provision of the water-absorbing sponge 503 can quickly clean the residual water on the top wall of the supporting upright plate 102, so that the residual water on the upper surface of the cutting platform formed by the combination of multiple supporting upright plates 102 can be quickly wiped clean. When the U-shaped plate 501 is pressed down by the ore, the water-absorbing sponge 503 will also be squeezed by the U-shaped plate 501 and the supporting upright plate 102, so that the water is quickly discharged. When the water-absorbing sponge 503 is reset again following the U-shaped plate 501, the water content inside the water-absorbing sponge 503 is greatly reduced, and then more water can be absorbed to ensure that the wiping and water-absorbing operation of the top wall of the supporting upright plate 102 is completed normally.
