Preferably, the bottom plate 12 and the top plate 13 are split structures, both of which are spliced ​​by multiple plates, and the adjacent plates are fastened by bolts for better transportation.

[0033] The bottom plate 12 , the top plate 13 , the base 9 and the four columns 11 form an accommodation space for placing the cutting device 3 . The cutting device 3 can move up and down in the accommodation space so that the cutting device 3 can cut the stone material arranged on the base 9 .

[0034] A plurality of locking devices 4 are respectively provided between the bottom plate 12 and the four columns 11 for locking the two correspondingly to each other. The locking devices 4 include anchor bolts 41 fixedly riveted to the base 9 and nuts 42 sleeved on the anchor bolts 41 through threaded connection. The lower end of the column 11 is provided with a support foot 111 that fits the upper surface of the bottom plate 12. The support foot 111 is provided with a first U-shaped groove 112 extending from the middle of the support foot 111 to the outside.

The present invention can be disassembled and assembled by loosening the nut 42 and then moving the column 11 horizontally, and has the advantages of simple structure, cost saving, and convenient disassembly and assembly.

[0036] The cantilever device 2 includes a support column 21 fixedly mounted on the frame 1 and a first cantilever 22 and a second cantilever 23 symmetrically arranged on the support column 21 along the axis direction of the support column 21. Specifically, the support column 21 extends in the vertical direction, and the first cantilever 22 and the second cantilever 23 both extend in the transverse direction.

[0037] Furthermore, the first cantilever 22 and the second cantilever 23 may be two cantilever arms of different lengths, or may be two cantilever arms of the same length. This embodiment is described by assuming that the length of the first cantilever 22 is greater than the length of the second cantilever 23 .

[0038] The first cantilever 22 is provided with an electric hoist 221 that moves along the length direction of the first cantilever 22 and a sling 222 that is installed on the electric hoist 221 and is driven to rise and fall by the electric hoist 221. The first cantilever 22 extends outward to the outer periphery of the frame 1. The sling 222 is used to suspend the roller 11 of the wire cutting machine to facilitate the replacement of the roller 11. The second cantilever 23 is provided with a counterweight block 231 that moves along the length direction of the second cantilever 23.

[0039] A rotating mechanism is provided at the upper end of the support column 21 for driving the first cantilever 22 and the second cantilever 23 to rotate. The rotating mechanism includes a first support 241 and a second support 242 arranged at the upper end of the support column 21, and a first rotating column 243 and a second rotating column 244 respectively rotatably installed on the first support 241 and the second support 242 through bearings. The first rotating column 243 and the second rotating column 244 are symmetrically arranged along the axis of the support column 21, the first cantilever 22 is fixedly connected to the first rotating column 243, and the second cantilever 23 is fixedly connected to the second rotating column 244.

[0040] Furthermore, the cantilever device 2 also includes a driving mechanism 25 for driving the first rotating column 243 and the second rotating column 244 to rotate synchronously, and the driving mechanism 25 includes a first gear 251 connected to the axis of the first rotating column 243, a second gear 252 connected to the axis of the second rotating column 244, a chain 253 arranged around the outer periphery of the first gear 251 and the second gear 252 and meshing therewith, and a driving motor (not shown in the figure) for driving the first gear 251 and / or the second gear 252 to rotate, so that the chain 253 is driven by the driving motor to rotate, so that the first rotating column 243 and the second rotating column 244 rotate synchronously, so that the first cantilever 22 and the second cantilever 23 are always on the same straight line. Of course, there are many other ways for the driving mechanism 25 of this embodiment to drive the first rotating column 243 and the second rotating column 244 to rotate synchronously, which will not be described in detail here.

[0041] Furthermore, the cantilever device 2 also includes a control system for receiving and sending signals. The first cantilever 22 and the second cantilever 23 are both provided with slide rails 223. The electric hoist 221 and the counterweight block 231 are respectively provided with pulleys 224, and are slidably connected along the corresponding slide rails 223. A pulley motor (not shown in the figure) is provided inside each pulley 224 for driving the corresponding electric hoist 221 or counterweight block 231 to slide. Each pulley motor is respectively communicated with the control system. Each pulley 224 is also provided with a pressure sensor (not shown in the figure) for detecting the load of the sling 222, and the pressure sensor is communicated with the control system.

[0042] The control system in this embodiment controls the driving motor so that the first cantilever 22 and the second cantilever 23 can achieve precise rotation under the synchronous rotation of the first rotating column 243 and the second rotating column 244; controls the pulley motor so that the pulley 224 on the electric hoist 221 and the counterweight block 231 can achieve precise movement; at the same time, the pressure sensor can accurately calculate the moving distance of the pulley 224 of the counterweight block 231, and the support column 21 can be balanced using the lever principle.

[0043] The above scheme is adopted: the pulley 224 on the electric hoist 221 can slide along the slide rail 223 on the first cantilever 22, and the pulley 224 on the counterweight block 231 can slide along; the control system sends a signal to the drive motor on the electric hoist 221 to drive the electric hoist 221 to slide, so that the electric hoist 221 reaches the material and lifts the material; at the same time, the pressure sensor on the pulley 224 transmits data to the control system, and after analysis by the control system, it sends a signal to the pulley 224 on the counterweight block 231 to move, thereby changing the position of the counterweight block 231, and using the lever principle to balance the support column 21.

[0044] Furthermore, a brake disc 26 is fixed on the first rotating column 243 and / or the second rotating column 244, and the brake disc 26 rotates synchronously with the corresponding first rotating column 243 or the second rotating column 244. A plurality of anti-rotation holes 261 are arranged at intervals along the circumferential direction on the brake disc 26, and an anti-rotation locking mechanism is also installed on the first support 241 and / or the second support 242, and the anti-rotation locking mechanism includes a positioning pin sleeve 271, a limiting pin 272 arranged in the positioning pin sleeve 271, and an elastic member 273 arranged between the limiting pin 272 and the positioning pin sleeve 271. An inner stop edge 274 is provided in the positioning pin sleeve 271, and one end of the limit pin 272 passing through the inner stop edge 274 is connected to a pull ring 275. The limit pin 272 is in the shape of a stepped shaft, and the elastic member 273 is sleeved on the outside of the limit pin 272. One end of the elastic member 27 presses on the inner stop edge 274. The limit pin 272 is used to pass through the second support 242 and extend into the stop hole 261 to stop the brake disc 26 from rotating. The second support 242 is provided with a limit through hole 276 for the limit pin 272 to pass through. In the initial state, the elastic member 273 is in an uncompressed state, and the limit pin 272 extends into the stop hole 261 to realize the limit locking of the corresponding first rotating column 243 or the second rotating column 244. The pull ring 275 is further pulled downward and rotated 90 degrees at the maximum displacement, so that the pull ring 275 can be blocked on the lower end surface of the positioning pin sleeve 271, and at the same time, the limit locking of the first rotating column 243 or the second rotating column 244 (that is, the first cantilever 22 and the second cantilever 23) is released.

[0045] Furthermore, an early warning device may be provided on the cantilever device 2 to remind relevant personnel to avoid the danger. The early warning device includes an early warning display device or an early warning playback device, the early warning display device may be a display light, and the early warning playback device may be a player.

[0046] Working principle:

[0047] When in use, through the principle of leverage, the counterweight blocks 231 at different positions can balance rollers 11 of different weights, and then the pulley motor is turned on to drive the first rotating column 243 or the second rotating column 244 to rotate, and the hoist 12 is driven to be directly above the roller 11, and then the electric hoist 221 is turned on to let the electric hoist 221 hook up the roller 11, and then the material is transferred to other places through the rotation of the rotating arm 21.

[0048] Preferably, the cutting device 3 includes a cutting frame 31, four guide posts 32 distributed at four corners of the cutting frame 31, a cutting assembly 33 arranged on the cutting frame 31 and used for cutting stone, and a lifting mechanism for driving the cutting frame 31 to move up and down so that the cutting assembly 33 can cut stone. The cutting frame 31 is provided with four first through holes 311 for the four guide posts 32 to pass through respectively, and the four guide posts 32 are arranged in the four first through holes 311 one by one. It is worth noting that the guide posts 32 of this embodiment can adopt a light rod guide post or a roller linear guide post. The roller linear guide post has high precision and is very smooth in operation, but the roller linear guide post is easy to get stuck after deformation, and the roller linear guide post is afraid of water ingress, and the ball is easy to rust; therefore, in this embodiment, the light rod guide post 32 made of ultra-high molecular polyethylene is adopted, which has higher wear resistance. Other feasible methods are not described in detail here.

[0049] Preferably, the lifting mechanism includes a ball screw 341 symmetrically arranged on the cutting frame 31 and located between the two guide pillars 32, and a driving motor 342 arranged on the top plate 13 and used to drive the two ball screws 341 to move synchronously. The cutting frame 31 is symmetrically provided with two second through holes 312 for the two ball screws 341 to pass through. The two ball screws 341 are respectively and one-to-one correspondingly and rotatably arranged in the two second through holes 312, and are threadedly connected with the second through holes 312. The middle part of the cutting frame 31 is provided with a channel 313 through which the stone to be cut passes when the cutting frame 31 is moved downward. The driving motor 342 of this embodiment can adopt a worm gear reducer.

[0050] The cutting assembly 33 includes guide wheels 331 arranged at the four corners of the cutting frame 31 in the horizontal direction, guide wheel motors 332 installed on the cutting frame 31 and respectively corresponding to the guide wheels 331, and a winding unit and an unwinding unit arranged on both sides of the frame 1. The output ends of each guide wheel motor 332 are respectively connected to the corresponding guide wheels 331. A rubber surface layer is laid on the guide wheel 331, and the guide wheel 331 is made of aviation aluminum material, and the rubber surface layer is made of ultra-high molecular polyethylene material. The guide wheel 331 made of lightweight aviation aluminum material reduces the lifting load of the cutting frame 31, and the outer cover is provided with a rubber surface layer of ultra-high molecular polyethylene material, which improves the wear resistance of the guide wheel 331.

[0051] Furthermore, the outer surface of the rubber surface layer is provided with a plurality of winding grooves 3311 for the diamond wires 333 to pass through. The diamond wires 333 sequentially pass around the winding grooves 3311 of the four guide wheels 331 to form a plurality of parallel cutting lines.

[0052] The winding unit and the unwinding unit are two winding devices with the same structure, each comprising a winding motor 3341, a winding wheel 3342 connected to the output shaft of the winding motor 3341, a guide wheel group 3343 and a tension control wheel group 3344. The emery wire 333 is connected to the winding motor 3341 after being guided by the winding wheel 3342, the guide wheel group 3343 and the tension control wheel group 3344, and the winding motor 3341 can reel in and unwind the wire.

[0053] The tension control wheel group 3344 includes a swing motor, a swing arm is connected to the power output end of the swing motor, and a balance wheel matching the emery wire 333 is connected to the swing arm. By controlling the swing of the swing arm, the balance wheel pulls and releases the emery wire 333 to adjust the tension of the emery wire 333.

[0054] When the emery wire 333 is wound, one end of the emery wire 333 is fixed to the winding wheel 3342 of the winding motor 3341 of the winding unit, and the other end of the emery wire 333 passes through the guide wheel group 3343 and the tension control wheel group 3344 in turn, and the emery wire 333 is coiled on the winding grooves 3311 of multiple guide wheels 331 in turn; the emery wire 333 is spirally wound between the multiple guide wheels 331; and then passes through another guide wheel group 3343, the tension control wheel group 3344, and the winding grooves 3311 of the four guide wheels 331 in turn, and then is fixed to the tension control wheel group 3344 and the guide wheel group 3343 of the unwinding unit, and then to the winding wheel 3342 of the winding motor 3341 of the unwinding unit. During the process of retracting and releasing the emery wire 333, one winding motor 3341 winds the wire, and the other winding motor 3341 releases the wire, and at the same time controls the driving motor 342 to work, so that the guide wheel 331 rotates synchronously, so that the emery wire 333 is transferred from the winding wheel 3342 of one winding motor 3341 to the winding wheel 3342 of another winding motor 3341. The emery wire 333 moves at high speed during the transfer process, and can be cut. After the emery wire 333 is completely transferred, the rotors of the two winding motors 3341 and the multiple driving motors 342 are driven to reverse, and the above movement is repeated to realize the transfer of the emery wire 333 back; by driving the emery wire 333 to transfer back and forth, cutting is realized through the emery wire 333. Specifically, the guide wheel motor 332 is a servo motor.

[0055] The working principle is: the driving motor 342 drives the ball screw 341 to rotate, so that the cutting frame 31 moves up and down smoothly in the accommodating space, and the vertically arranged linear guide column 32 can further stabilize the path of the cutting frame 31 when moving up and down, ensuring that it will not shake when moving up and down, and then the stone arranged on the base 9 is planned to be cut.

[0056] This embodiment also includes a liquid cooling mechanism for cooling various parts arranged on the frame 1, and the main shaft of the roller roller 331 and the roller drive motor 35 are both provided with an inlet and an outlet for the coolant to enter and exit; the liquid cooling mechanism includes a cold storage tank 51 arranged on the frame 1 and filled with coolant, and a cooling circulation pipeline connected to the cold storage tank 51 and used for circulating the coolant, and the two ends of the cooling circulation pipeline are respectively a water inlet and a water outlet, and the water inlet and the water outlet are respectively connected to the cold storage tank 51, and there are multiple cooling circulation pipelines, which are respectively arranged on the main shaft of the drive motor 35 and the roller roller 331. Specifically, the coolant of this embodiment is one or a mixture of at least two of water, alcohols, molten salts, thermal oil, ion-like fluids, and phase change materials. The following is a detailed description of this embodiment using water as a coolant.

[0057] The liquid cooling mechanism also includes a water pump 52, a first water distributor 53, a second water distributor 54 and a heat exchanger 55. The water pump 52 drives the coolant in the cold storage box 51 to enter through the first water distributor 53 from the inlet of the main shaft of the roller roller 331 and the inlet of the roller drive motor 35 to absorb the heat released by the main shaft of the roller roller 331 and the roller drive motor 35, and the water pump 52 drives the coolant to flow out from the outlet of the main shaft of the roller roller 331 and the outlet of the roller drive motor 35 from the second water distributor 54, and exchanges the heat released by the main shaft of the roller roller 331 and the roller drive motor 35 with the heat exchanger 55, and mixes with the coolant in the cold storage box 51 and is cooled and stored in the cold storage box 51.

Specifically, the rollers 331 are made of lightweight aviation aluminum, and the rubber surface layer is made of high molecular polyethylene.

[0066] The winding structure 37 includes a winding motor 371, a wire arrangement device 372, a guide wheel group 373 and a tension control wheel group 374. The roller 331 is provided with a plurality of evenly distributed winding grooves 332. The diamond yarn 38 is connected between the winding grooves 332 and the winding structure 37. The diamond yarn 38 is connected to the working end of the winding motor 371 after being guided by the wire arrangement device 372, the guide wheel group 373 and the tension control wheel group 374. A winding wheel is installed on the working end of the winding motor 371, and the winding motor 371 can reel in and release the wire; the wire arrangement device 372 includes a wire arrangement wheel installed on a linear guide rail, and the wire arrangement device 372 is used for arranging the wire when the winding motor 371 is winding. During the winding and releasing process, the wire arrangement wheel on the wire arrangement device 372 gradually moves forward and backward, so that the diamond yarn 38 is fully wound on the winding wheel or released from the winding wheel;

[0067] The guide wheel group 373 includes a straight rod, a slide is slidably connected to the straight rod, a locking bolt matching the straight rod is installed on the slide, the position of the slide is adjustable, an inclined guide wheel facing the roller is installed on the slide, the diamond yarn 38 is guided to the roller roller 331 by the inclined guide wheel, and the position of the diamond yarn 38 output by the inclined guide wheel is adjusted by adjusting the position of the slide, so that the diamond yarn 38 matches the winding groove 332 at different positions on the roller roller 331;

[0068] The tension control wheel group 374 includes a swing motor, a swing arm is connected to the power output end of the swing motor, and a guide wheel matching the diamond yarn 38 is connected to the swing arm; by controlling the swing arm to swing, the guide wheel pulls and releases the diamond wire, so as to adjust the tension of the diamond wire;

[0069] When the diamond yarn 38 is wound, one end of the diamond yarn 38 is fixed to a winding wheel of a winding motor 371, and the other end of the diamond yarn 38 is guided to a plurality of rollers after passing through a wire arrangement device 372, a tension control wheel group 374 and a guide wheel group 373 in sequence, and the diamond yarn 38 is wound on the winding grooves of the plurality of rollers in sequence; so that the diamond yarn 38 is spirally wound between the plurality of rollers;

[0070] After the end of the coiled diamond yarn 38 is led out from the lower roller 331, it passes through another guide wheel group 373, a tension control wheel group 374, and a wire arrangement device 372 in sequence, and is fixed to the winding wheel of another winding motor 371. The diamond yarn 38 of this embodiment passes around a pair of roller rollers 331 and a pair of roller rollers 331 and is connected to the winding structure in the two integrated boxes 5; during the process of retracting and releasing the diamond yarn 38, one winding motor 371 is wound, and the other winding motor 371 is unwound, and the motor 371 is controlled at the same time. 203 works to make the roller 331 rotate synchronously, so that the diamond yarn 38 is transferred from the winding wheel of one winding motor 371 to the winding wheel of another winding motor 371. The diamond yarn 38 moves at high speed during the transfer process and can be cut. After the diamond yarn 38 is completely transferred, the two winding motors 371 and the rotors of multiple motors 203 are driven to reverse, and the above movement is repeated to realize the transfer of the diamond yarn 38 back; by driving the diamond yarn 38 to transfer back and forth, the diamond yarn 38 is cut;

[0071] This embodiment uses diamond wire cutting. Compared with the cutting seam greater than 3mm in the existing process, the cutting gap of this solution is small, which can be less than 0.5mm, with relatively less debris and a high stone output rate. Compared with the rigid tool cutting in the existing technology, the vibration force is large, which easily causes loose stone to be chopped. This solution uses diamond wire for flexible cutting, which is less likely to cause stone to be shattered, and the cutting surface is smoother, which is conducive to later grinding processing.

[0072] When this embodiment is working, the stone is fed into the fixed frame 1 through the feeding platform, and then the cutting frame 2 is moved in the vertical direction by controlling the ball screw. At this time, the motor 203 and the winding structure are controlled to rotate the roller, thereby driving the diamond yarn 38 to move, and the stone is cut by the diamond yarn 38.

[0073] The working principle is: the driving motor 342 drives the ball screw 341 to rotate, so that the cutting frame 31 can move up and down smoothly in the accommodating space, and the vertically arranged linear guide rail 32 can further stabilize the path of the cutting frame 31 when moving up and down, ensuring that it will not shake when moving up and down, and then the stone 9 arranged on the base 1 can be planned cut.

[0074] When the present invention leaves the factory, the device can be divided into a cutting device 3 with a more complex structure, wherein the longer guide rail 32 and the ball screw 341 in the cutting device 3 can also be disassembled. This part is more difficult to assemble and can be assembled into one piece by engineers in the factory. At the same time, the top plate 23 formed by splicing multiple plates can be transported to the site together. When transporting the equipment, a reinforced concrete base 1 can be pre-made on site, and a number of long screws 41 can be pre-embedded in the base 1.

[0075] By adopting the above-mentioned design scheme, the beneficial effects of the present invention are: when working, by placing the stone on the base and in the channel of the cutting frame, and then driving the cutting frame to move up and down in the accommodating space through the lifting mechanism, the cutting assembly cuts the stone; compared with the traditional method, the present invention changes the stone lifting cutting method to the cutting frame lowering cutting method, which has lower power consumption, smaller jitter, good overall stability, and improved stone cutting quality; the present invention also divides the entire equipment into several parts, which not only solves the transportation difficulty, but also assembles the more complex structure and then transports it to the site, saving labor costs.

[0076] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
