Description

Technical Field

[0001] The present application relates to the technical field of stone cutting, and in particular to a lifting assembly and a stone wire cutting machine. Background Art

[0002] Existing wire-cut stone cutting machines typically include a cutting chamber assembly and a lifting assembly located within the cutting chamber. After the stone blocks are transported into the cutting chamber, the lifting assembly located within the cutting chamber is able to move the stone blocks up and down, thereby enabling the lifting assembly to lift and lower the stone during the wire-cut feeding and withdrawal processes. However, the lifting assembly is located within the cutting chamber and is affected by the vibrations of the high-speed rotation of the main rollers within the cutting chamber, making the lifting and lowering process unstable. Therefore, designing a new lifting assembly and wire-cut stone cutting machine to improve the stability of the lifting assembly in driving the stone lifting and lowering, as well as the stability of the stone cutting, has become a technical problem that urgently needs to be solved in the field of stone cutting machines.

[0036] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0037] See Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a stone wire cutting machine 1 according to an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a stone wire saw 1, which includes a base assembly 3, a cutting chamber assembly 4, and a lifting assembly 5. The top of the base assembly 3 has a material lifting opening 301 for lifting the stone material. The cutting chamber assembly 4 is located on top of the base assembly 3. The lifting assembly 5 is used to lift and lower the stone material 100 on the lifting platform assembly 51. When the lifting assembly 5 drives the stone material 100 up through the material lifting opening 301 and into the interior of the cutting chamber assembly 4, the wire mesh mechanism in the cutting chamber assembly 4 is able to cut the stone material 100 when in operation.

[0038] In some embodiments, the stone wire cutting machine 1 also includes a base assembly 2. The base assembly 2 generally refers to the installation foundation of each facility in the stone wire cutting machine 1, and the installation foundation can be a concrete foundation. The top of the base assembly 2 can be provided with facilities such as a shuttle track, a base track for the movement of the rough material vehicle assembly 53, a base embedded steel plate, and a cutting fluid drainage channel. The base assembly 3 is arranged at the top of the base assembly 2 and is fixedly connected to the base embedded steel plate. The base assembly 3 is used to carry the cutting chamber assembly 4 and the lifting assembly 5. The base assembly 3 can also be used to carry key facilities of the stone wire cutting machine 1 such as the second-floor working platform and the control cabinet.

[0039] In the present embodiment, the cutting chamber assembly 4 refers to the component assembly in the stone cutting area. The cutting chamber assembly 4 can be located at the top of the base assembly 3. The cutting chamber assembly 4 can include a cutting chamber frame and a wire-mesh mechanism fixedly mounted on the cutting chamber frame. The wire-mesh mechanism is the actuator for cutting the stone block 100.

[0040] See Figure 2 , Figure 2 FIG. 1 is a partial structural diagram of a stone wire cutting machine 1 according to an embodiment of the present application. Figure 2 As shown, the embodiment of the present application provides a lifting assembly 5, which can be applied to Figure 1 The stone wire saw 1 shown in FIG. The lifting assembly 5 includes a lifting platform assembly 51 and at least one lifting drive assembly 52. Specifically, the lifting platform assembly 51 is disposed within the base assembly 3; the lifting drive assembly 52 is disposed on the base assembly 3 and connected to the lifting platform assembly 51. The lifting drive assembly 52 is used to drive the lifting platform assembly 51 to move up and down relative to the base assembly 3. The lifting platform assembly 51 is used to support the stone block 100.

[0041] In the above technical solution, the lifting drive assembly 52 is arranged on the base assembly 3, so that the lifting drive assembly 52 is separated from the cutting chamber assembly 4 and is independent of each other, which can reduce the negative impact of the vibration caused by the high-speed rotation of the main roller in the cutting chamber assembly 4 on the smooth lifting of the lifting platform assembly 51, and effectively improve the stability of the lifting platform assembly 51 and the stone block 100 during the lifting process, thereby improving the stability and reliability of the stone wire cutting machine 1 in cutting the stone block 100.

[0042] See Figures 3 and 4 , Figure 3 This is a schematic diagram of the overall structure of the base assembly 3 shown in an embodiment of the present application. Figure 4 This is a schematic diagram of the overall structure of the base positioning assembly 35 shown in an embodiment of the present application. Figures 2 to 4As shown, the base assembly 3 may include a plurality of columns 31 and a plurality of connecting beams 32, at least one connecting beam 32 being provided between two adjacent columns 31, each column 31 and each connecting beam 32 constituting a lifting space 300 for accommodating the lifting platform assembly 51, a block lifting opening 301 for lifting the stone block 100 to enter or leave the cutting chamber, and a block cart entrance 302 for the block cart assembly 53 to move into the lifting space 300.

[0043] In some embodiments, the top of each column 31 has a mounting surface 310 for the cutting chamber assembly 4 and the lifting assembly 5, and a positioning ring 33 and a positioning key 34 are provided on the mounting surface 310 to realize the installation and positioning of each component in the stone wire cutting machine 1 (for example, the positioning ring 33 is used to install the elevator 5221 in the lifting drive assembly 52); the side wall surface of each column 31 adjacent to the lifting space 300 can be used to install the guide rail in the guide rail assembly; the side wall surface of each column 31 opposite to or non-adjacent to the lifting space 300 can be used to install other components, such as the second-floor working platform pillars.

[0044] In some embodiments, the connecting beams 32 include a transverse connecting beam 321 and a longitudinal connecting beam 322. The transverse connecting beam 321 and the longitudinal connecting beam 322 are perpendicular to each other. The two transverse connecting beams 321 extend in a first direction A, and the two ends of each transverse connecting beam 321 are respectively connected to the top ends of two adjacent columns 31. The two longitudinal connecting beams 322 extend in a second direction B, and the two ends of each longitudinal connecting beam 322 are respectively connected to the top ends of two adjacent columns 31. Figure 3 As shown, two transverse connecting beams 321 , two longitudinal connecting beams 322 and four upright posts 31 form a base assembly 3 having a lifting space 300 , a block lifting port 301 and a block vehicle inlet 302 .

[0045] In some embodiments, the base assembly 3 may further include two base connecting beams 323. The base connecting beams 323 extend parallel to the transverse connecting beams 321. Each base connecting beam 323 extends in a first direction A, and each end of each base connecting beam 323 is connected to the bottom ends of two adjacent columns 31. Furthermore, the transverse connecting beams 321, the longitudinal connecting beams 322, and the base connecting beams 323 may each be provided with positioning stoppers and adjustment mechanisms to facilitate alignment of the overall frame of the base assembly 3 when each connecting beam 32 is connected to the column 31.

[0046] In the above technical solution, the base assembly 3 composed of multiple columns 31 and multiple connecting beams 32 has high rigidity and stability, and can serve as a basic supporting structure to stably and reliably position and support components such as the cutting chamber assembly 4 and the lifting assembly 5.

[0047] like Figure 4As shown, in some embodiments, the base assembly 3 further includes a base positioning assembly 35. The base positioning assembly 35 may include an embedded welded steel plate 351, an adjustment shim, and a positioning fixture 352. The top of the embedded welded steel plate 351 is provided with an adjustment screw bolt and a tightening bolt for installing the column 31, and the bottom of the embedded welded steel plate 351 is provided with an anchor bolt 353. The anchor bolt 353 can be fixedly connected to the foundation assembly 2 (installation foundation) by pouring, and one end of the anchor bolt 353 passes through the embedded welded steel plate 351 toward the top to engage the column 31. The adjustment shim is provided at the top of the embedded welded steel plate 351, and the adjustment shim is used to adjust the height of the column 31. Four embedded welded steel plates 351 can be provided, and the relative position between two adjacent embedded welded steel plates 351 can be adjusted by the positioning fixture 352.

[0048] See Figure 5 , Figure 5 This is a schematic diagram of the overall structure of the lifting assembly 5 shown in an embodiment of the present application. Figures 2 to 5 As shown, along the first direction A of the base assembly 3, a lifting drive assembly 52 is provided on each side of the lifting platform assembly 51. The lifting assembly 5 may also include a block trolley assembly 53 for carrying the stone block 100. When the stone wire saw 1 is performing stone cutting, the block trolley assembly 53 is positioned atop the lifting platform assembly 51, and the lifting platform assembly 51 is used to carry the block trolley assembly 53. Furthermore, the first direction A of the base assembly 3 is perpendicular to the direction in which the cutting line of the stone wire saw 1 extends, and / or the first direction A of the base assembly 3 is perpendicular to the direction in which the block trolley assembly 53 is loaded and unloaded.

[0049] Because stone blocks are generally large, to ensure that the stone slabs produced by the stone wire saw 1 are straighter, the lifting platform 511 should remain as parallel to the cutting wire mesh as possible while the lifting assembly 5 drives the block cart assembly 53 upward via the lifting drive assembly 52, and the lifting speed of the lifting platform 511 should be as stable as possible. Therefore, the lifting assembly 5 is one of the key components of the stone wire saw 1 that affects the accuracy of stone cutting.

[0050] In the embodiment of the present application, each lifting drive assembly 52 may include a servo motor 5211, and the lifting drive assembly 52 is driven by the servo motor 5211. The lifting assembly 5 (stone wire saw 1) can control the operating parameters of each servo motor 5211 through electrical control components such as a controller, thereby ensuring that each lifting drive assembly 52 drives the lifting platform assembly 51 to move upward and downward at the same lifting speed and direction, ultimately achieving stable horizontal lifting of the lifting platform assembly 51 and the stone block 100.

[0051] In the embodiment of the present application, the block cart assembly 53 includes a block cart frame 531 and a block cart guardrail 532. Two block cart guardrails 532 are arranged on either side of the block cart frame 531 along a first direction A. The stone block 100 to be cut is placed on the block cart frame 531 and between the two block cart guardrails 532. Because the stone wire saw 1 needs to cut the stone block 100, the block cart guardrails 532 need to avoid the cutting line. Therefore, the extension direction of a single block cart guardrail 532 is generally located on one side of the cutting line and parallel to the extension direction of the cutting line. That is, the extension direction of a single block cart guardrail 532 placed on the lifting platform assembly 51 is the second direction B.

[0052] In the above technical solution, the two lifting drive assemblies 52 are respectively arranged on both sides of the lifting platform assembly 51 along the first direction A, and the first direction A is perpendicular to the extension direction of the cutting line of the stone wire cutting machine 1. When the lifting speeds of the two lifting drive assemblies 52 are inconsistent, and the lifting platform assembly 51 is tilted toward one side (when tilted toward the position of one of the lifting drive assemblies 52), the stone block 100 can still be blocked by the block car guardrail 532 in the tilted state, reducing the probability of the stone block 100 sliding, tipping, and falling on the lifting platform assembly 51, improving the stability and reliability of the lifting assembly 5 to drive the stone block 100 to rise and fall, and thereby improving the stability of the cutting of the stone block 100.

[0053] In the above technical solution, two lifting drive assemblies 52 are arranged on either side of the lifting platform assembly 51 along a first direction A, and the first direction A is perpendicular to the loading and unloading direction of the block cart assembly 53. This reduces the probability of the block cart assembly 53 or the stone block 100 moving laterally on the lifting platform 511 when the lifting platform assembly 51 is tilted toward one side (when tilted toward the location of one of the lifting drive assemblies 52). The stone block 100 is blocked by the block cart guardrail 532 and is less likely to slide laterally when the lifting platform 511 is tilted toward one side. When the loading and unloading direction of the block cart assembly 53 is perpendicular to the first direction A, when the block cart assembly 53 moves in the loading and unloading direction, the block cart wheels 5335 and the lifting platform assembly 51 are generally in rolling contact. When the block cart assembly 53 moves laterally along the first direction A, the block cart wheels 5335 and the lifting platform assembly 51 are generally in sliding contact. Sliding contact has greater friction than rolling contact, so the probability of the block car assembly 53 moving laterally along the first direction A is reduced. As a result, the lifting assembly 5 improves the stability and reliability of lifting the stone block 100, thereby improving the stability of cutting the stone block 100.

[0054] See Figure 6 , Figure 6 This is a schematic diagram of the overall structure of the lifting drive assembly 52 shown in an embodiment of the present application. Figures 2 to 6As shown, each lifting drive assembly 52 includes a drive unit 521 and at least one transmission unit 522. The transmission unit 522 includes a screw rod 5222 and an elevator 5221. The elevator 5221 is fixed on the base assembly 3, and the elevator 5221 is connected to the drive unit 521. One elevator 5221 is mounted on a screw rod 5222, and the screw rod 5222 is connected to the lifting platform assembly 51. In the above technical solution, the transmission unit 522 cooperates with the elevator 5221 through the screw rod 5222 to realize the transmission between the drive unit 521 and the lifting platform assembly 51, so that the lifting drive assembly 52 has a higher load capacity, higher transmission efficiency, higher transmission accuracy and a simpler structure. The lifting drive assembly 52 drives the lifting platform assembly 51 to perform lifting movements more smoothly, with lower maintenance costs and longer service life.

[0055] In some embodiments, each lifting drive assembly 52 includes a drive unit 521 and two transmission units 522. Specifically, in the same lifting drive assembly 52 located on the same side of the lifting platform assembly 51, the two transmission units 522 are symmetrically arranged at both ends of the drive unit 521 and are in transmission connection with the drive unit 521. In the above technical solution, the two transmission units 522 in each lifting drive assembly 52 are symmetrically arranged at both ends of the same drive unit 521, so that the transmission distance from the drive unit 521 of the same lifting drive assembly 52 to the two transmission units 522 (each screw rod 5222) is equal, thereby making the lifting power at both ends of each drive unit 521 consistent, thereby improving the stability of the lifting drive assembly 52 in driving the lifting platform assembly 51 to rise and fall.

[0056] In some embodiments, a plurality of screw rods 5222 are arranged one by one at each corner point of the lifting platform assembly 51, and each screw rod 5222 is vertically arranged compared to the top surface of the lifting platform 511. Figure 5 For example, the lifting platform 511 of the lifting platform assembly 51 is a square structure, and the lifting assembly 5 may include two lifting drive assemblies 52 respectively arranged on both sides of the lifting platform assembly 51, and each lifting drive assembly 52 includes a drive unit 521 and two transmission units 522. Furthermore, the screw rods 5222 of the four transmission units 522 are respectively fixedly connected to the four corners of the lifting platform 511 to drive the lifting platform 511 and the stone block 100 to perform lifting and lowering movements. In the above technical solution, multiple screw rods 5222 can be arranged around the lifting platform 511 and each screw rod 5222 is arranged vertically at each corner point of the lifting platform 511 relative to the top surface of the lifting platform 511, so that the multiple lifting drive assemblies 52 jointly drive the lifting platform 511 and the stone block 100 to lift and lower horizontally and stably.

[0057] In some embodiments, the drive unit 521 may include a servo motor 5211 and a reducer 5212, wherein the servo motor 5211 is connected to the reducer 5212, and the reducer 5212 is connected to the transmission unit 522. Specifically, each drive unit 521 includes a servo motor 5211 and a reducer 5212, wherein the output shaft of the servo motor 5211 is connected to the input shaft of the reducer 5212. The reducer 5212 may be a double-extension shaft reducer, wherein the two output shafts of the double-extension shaft reducer are arranged opposite to each other and extend toward both sides of the reducer 5212, and one output shaft is in transmission connection with an elevator 5221 of a transmission unit 522. In the above technical solution, a double-extension shaft reducer can provide power to two elevators 5221 at the same time, thereby improving the consistency of the lifting and lowering speeds of the screw rods 5222 on both sides.

[0058] In some embodiments, the elevator 5221 may include an elevator support 5226, a worm gear transmission pair 5227 and a rotating nut 5228 disposed within the elevator support 5226. Specifically, the elevator support 5226 is fixed to the base assembly 3, the worm gear transmission pair 5227 is connected to the rotating nut 5228, and the worm wheel, worm, and rotating nut 5228 in the worm gear transmission pair 5227 are all movably mounted within the elevator support 5226. A worm gear transmission pair 5227 is connected to an output shaft of a reducer 5212 (transmission unit 522) and a rotating nut 5228. The worm of the worm gear transmission pair 5227 is connected to the output shaft of the reducer 5212 via a transmission shaft 5223 and can rotate synchronously with the output shaft of the reducer 5212. The worm wheel of the worm gear transmission pair 5227 cooperates with the worm, and the worm can drive the worm wheel to rotate. The worm wheel is also connected to the rotating nut 5228. When the servo motor 5211 is started and drives the output shaft of the reducer 5212 to rotate, the output shaft of the reducer 5212 is driven by the worm gear transmission pair 5227, which drives the rotating nut 5228 to rotate within the elevator support 5226. Each rotating nut 5228 is mounted on a screw rod 5222. When the rotating nut 5228 rotates, it drives the screw rod 5222 to rise and fall along the axial direction of the screw rod 5222, thereby driving the lifting platform assembly 51 to move up and down.

[0059] In some embodiments, the transmission unit 522 further includes an elastic protective cover 5224, which is sleeved on the outside of a lead screw 5222 and telescopically disposed between the elevator 5221 and the lifting platform assembly 51. In the above technical solution, the elastic protective cover sleeved on the outside of each lead screw 5222 not only ensures that the lead screw 5222 can drive the lifting platform assembly 51 to move upward and downward without hindrance, but also reduces the probability of cutting fluid splashing onto the surface of the lead screw 5222, thereby affecting the coordination between the lead screw 5222 and the elevator 5221.

[0060] See Figure 7 , Figure 7 This is a partial schematic diagram of an embodiment of the present application showing the installation of the lifting drive assembly 52 on the base assembly 3. Figures 2 to 7 As shown, for the same lifting drive assembly 52, a drive unit 521 is fixed to a longitudinal connecting beam 322, an elevator 5221 is located at one end of the same longitudinal connecting beam 322, and one end of a screw rod 5222 passes through the elevator 5221 along the lifting direction C of the lifting platform assembly 51 and is connected to the lifting platform 511 in the lifting space 300. Furthermore, for the same lifting drive assembly 52, two elevators 5221 are symmetrically arranged at both ends of the same longitudinal connecting beam 322. A servo motor 5211 and a double-extension shaft reducer are fixed to the longitudinal connecting beam 322, which are transmission-connected to the two elevators 5221.

[0061] In the above technical solution, each elevator 5221 is mounted on each column 31 of the base assembly 3, and the servo motor 5211 and reducer 5212 are mounted on the longitudinal connecting beam 322 of the base assembly 3. This allows the installation position of the lifting drive assembly 52 to be separated from the cutting chamber assembly 4. This reduces the vibration caused by the high-speed rotation of the main roller in the cutting chamber assembly 4, and is conducive to improving the smoothness of the lifting and lowering movement of the lifting platform assembly 51 and the stone block 100, thereby improving the stability of the cutting operation. The lifting drive assembly 52 provided in this embodiment of the application has a simple structure. Installation on the base assembly 3 makes the overall structure more stable and reliable, and further improves the lifting accuracy.

[0062] See Figures 8 and 9 , Figure 8 This is a top view schematic diagram of a lifting platform assembly 51 installed on a base assembly 3 according to an embodiment of the present application; Figure 9 This is a schematic diagram of the overall structure of the lifting platform assembly 51 shown in an embodiment of the present application. Figures 2 to 9 As shown, the lifting assembly 5 further includes at least one V-shaped guide rail assembly 54 and at least one planar guide rail assembly 55 . The V-shaped guide rail assembly 54 and the planar guide rail assembly 55 are arranged on the same side of the lifting platform assembly 51 along the first direction A.

[0063] Furthermore, the lifting assembly 5 may include two V-shaped guide rail assemblies 54 and two planar guide rail assemblies 55. Along the second direction B of the base assembly 3, a V-shaped guide rail assembly 54 and a planar guide rail assembly 55 are respectively provided on either side of the lifting platform assembly 51. The V-shaped guide rail assembly 54 and the planar guide rail assembly 55 are provided at opposite ends of the same side of the lifting platform assembly 51 (near the corners of the lifting platform 511) along the first direction A, and the line connecting the two V-shaped guide rail assemblies 54 and the line connecting the two planar guide rail assemblies 55 are both parallel to the second direction B.

[0064] In some embodiments, each V-shaped guide rail assembly 54 includes a V-shaped guide rail 541 and a V-shaped guide rail 542 that cooperate with each other; each planar guide rail assembly 55 includes a planar guide rail 551 and a planar guide rail 552 that cooperate with each other. Specifically, a V-shaped guide rail 541 and a planar guide rail 551 are arranged at both ends of the same side of the lifting platform 511 along a first direction A, and the line connecting the two V-shaped guide rails 541 and the line connecting the two planar guide rails 551 are both parallel to the second direction B. The V-shaped guide rail 542 and the planar guide rail 552 are both arranged in the lifting direction of the lifting platform assembly 51 (i.e., the extension direction of the V-shaped guide rail 542 and the planar guide rail 552 is the lifting direction C of the lifting platform assembly 51) and are respectively connected to the side walls of each column 31 of the base assembly 3.

[0065] In some embodiments, the base assembly 3 further includes an extension bracket 36, which is fixed to the bottom end of a column 31. The extension bracket 36 is used to extend the mounting surface 310 of the V-shaped guide rail 542 or the planar guide rail 552 on the column 31. A planar guide rail 552 can be vertically fixed to the side wall of a column 31 using a stainless steel plate, and a V-shaped guide rail 542 can also be vertically fixed to the side wall of a column 31 using a stainless steel plate. The mounting surfaces 310 of the planar guide rails 552 and the V-shaped guide rails 542 on each column 31 are the side wall surfaces adjacent to each column 31 and the lifting platform assembly 51, and the layout orientation and spacing distance of each planar guide rail 552 and each V-shaped guide rail 542 on the base assembly 3 are consistent with the layout orientation and spacing distance of each planar slide rail 551 and each V-shaped slide rail 541 on the lifting platform 511, so as to realize the one-to-one matching between the planar slide rails 551 and the planar guide rails 552, and the one-to-one matching between the V-shaped slide rails 541 and the V-shaped guide rails 542, thereby playing a good guiding role in the lifting movement of the lifting platform assembly 51.

[0066] In the above technical solution, both the planar guide rail assembly 55 and the V-shaped guide rail assembly 54 can provide guidance for the lifting movement of the lifting platform assembly 51, making the lifting of the lifting platform 511 more stable and reliable. Specifically, the V-shaped slide rail 541 cooperates with the V-shaped guide rail 542 to limit the lifting platform 511 in the first direction A, which can reduce the left and right shaking of the lifting platform assembly 51 in the first direction A during the lifting process. The two sets of planar slide rails 551 cooperate with the planar guide rail 552 to limit the lifting platform 511 in the second direction B, which can reduce the forward and backward shaking of the lifting platform assembly 51 in the second direction B during the lifting process. At the same time, the planar slide rail 551 can be offset left and right along the first direction A on the planar guide rail 552, which can appropriately offset the deformation of the first direction A of the lifting assembly 5 due to factors such as vibration during the stone cutting process, so that the planar slide rail 551 can slide smoothly on the planar guide rail 552, and the V-shaped slide rail 541 can slide smoothly on the V-shaped guide rail 542, reducing the probability of each guide rail component being stuck due to excessive deformation and the lifting platform component 51 being unable to continue lifting.

[0067] In some embodiments, the lifting assembly 5 further includes a tensioner 56. On one side of the lifting platform assembly 51, two tensioners 56 are connected to a V-shaped rail 541 and a planar rail 551, respectively. The tensioners 56 provide a certain preload force for the V-shaped rail 541 and the planar rail 551, allowing them to fit tightly against the corresponding V-shaped guide rail 542 and the planar guide rail 552, thereby improving the guiding stability of the lifting platform 511 during lifting motion.

[0068] See Figure 10 , Figure 10 FIG. 5 is a schematic diagram showing the connection between the lifting platform assembly 51 and the lifting drive assembly 52 according to an embodiment of the present application. Figure 10 As shown, the transmission unit 522 also includes a screw pad 5225, and a screw pad 5225 is connected to the bottom end of a screw 5222. The screw 5222 is connected to the lifting platform 511 through the step surface between the screw pad 5225 and the lifting platform 511.

[0069] In the embodiment of the present application, the lifting platform assembly 51 includes a lifting platform 511, and the screw, screw pad and lifting platform 511 are fixedly connected by bolts. The screw pad 5225 and the lifting platform 511 are connected at the joints with a stepped structure 5220. The screw pad 5225 fixed at the bottom end of the screw 5222 can bear a larger load, and the screw pad 5225 has a higher structural strength. On this basis, the screw pad 5225 can also assist in adjusting the gap between each screw 5222 and the lifting platform 511. In the embodiment of the present application, the screw pad 5225 can be separately developed and installed in conjunction with the screw 5222.

[0070] See Figures 11 to 12 , Figure 11 This is a schematic diagram of the assembly of a lifting platform assembly 51 and a rough material vehicle assembly 53 according to an embodiment of the present application; Figure 12 This is a schematic diagram of the assembly of the lifting platform assembly 51 and the rough material vehicle assembly 53 shown in an embodiment of the present application. Figures 11 to 12 As shown, the lifting platform assembly 51 can include a lifting platform 511 and at least one positioning block 513, which is disposed on the top surface of the lifting platform 511. The bottom end of the rough material cart assembly 53 is also provided with at least one positioning block 513. Specifically, the positioning blocks 513 connected to the bottom end of the rough material cart assembly 53 are equal in number to the positioning blocks 513 disposed on the top surface of the lifting platform 511, and their shapes and positions correspond one-to-one and match.

[0071] In some embodiments, the positioning block 513 on the lifting platform 511 has a V-shaped protrusion, and the positioning block 513 on the rough material cart assembly 53 has a V-shaped groove that matches the V-shaped protrusion. Multiple positioning blocks 513 are respectively arranged at the four corners of the lifting platform 511 and the four corners of the rough material cart, and the positioning and matching direction of the V-shaped protrusion and the V-shaped groove is the second direction B, that is, the loading and unloading direction of the rough material cart assembly 53. Specifically, the positioning block 513 on the lifting platform 511 is connected to the lifting platform 511 via a positioning block base 514. The positioning block base 514 is welded to the lifting platform 511 after it is assembled. The positioning block 513 is connected to the positioning block base 514 via a pre-machined matching groove on the positioning block base 514. The positioning block 513 installed on the lifting platform 511 requires high positioning accuracy to achieve accurate matching with the positioning block 513 connected to the rough material cart assembly 53. Multiple positioning blocks 513 can be welded to the bottom end of the rough material cart assembly 53. During the lifting process of the lifting platform assembly 51 , the lifting platform assembly 51 cooperates with the positioning block 513 to support and position the rough material vehicle assembly 53 .

[0072] In the above technical solution, the split-type positioning block 513 is more conducive to fitting and alignment, and has a better load-bearing function for the rough material car assembly 53, which can effectively improve the positioning accuracy and loading stability of the rough material car assembly 53 on the lifting platform assembly 51. In addition, the replacement cost of the split V-shaped positioning block 513 after wear is lower, and its practicality is higher.

[0073] In some embodiments, the lifting platform assembly 51 may further include a limit plate 512, which is used to limit the moving distance of the rough material vehicle, play an initial positioning role for the rough material vehicle, and improve the positioning efficiency and positioning accuracy of the rough material vehicle. Specifically, the limit plate 512 may include a limit support 5121 and a buffer block 5122. The limit support 5121 is fixed on the lifting platform 511, and the buffer block 5122 is arranged on the side of the limit support 5121 close to the center of the lifting platform 511. After the limit plate 512 is installed on the lifting platform 511, there is a small gap between the limit plate 512 and the positioning block 513 to achieve adaptive positioning of the rough material vehicle assembly 53 on the lifting platform assembly 51. The two limit plates 512 are arranged on the same side of the lifting platform 511, and are respectively located on the side of the two positioning blocks 513 away from the center of the lifting platform 511 along the second direction B.

[0074] In some embodiments, the lifting platform assembly 51 also includes a rough material car guide rail 515, and there are two groups of rough material car guide rails 515. Each group of rough material car guide rails 515 is arranged and extended in the second direction B, and the two groups of rough material car guide rails 515 are arranged in parallel on the top surface of the lifting platform 511 along the first direction A according to the rough material car gauge. At both ends of the rough material car guide rail 515, there is a guide rail space 516 on the lifting platform 511. When the lifting platform 511 descends to the bottom in the lifting space 300, the basic guide rail 21 on the basic assembly 2 extends toward the top of the lifting platform 511 through the guide rail space 516 on the lifting platform 511, complementing the rough material car guide rail 515 to allow the rough material car assembly 53 to continue to move; when the lifting platform 511 is lifted to a certain height in the lifting space 300, the rough material car wheel 5335 originally on the basic guide rail 21 is suspended in the air, and the lifting platform 511 cooperates to support the rough material car and limit the movement of the rough material car through the positioning block 513.

[0075] See Figure 13 , Figure 13 FIG. 5 is a schematic diagram of the overall structure of a rough material vehicle assembly 53 according to an embodiment of the present application. Figure 13 As shown, the rough material vehicle assembly 53 includes a rough material vehicle frame 531 , a rough material vehicle guardrail 532 , and a rough material vehicle power assembly 533 .

[0076] In some embodiments, the top of the stone cart frame 531 can be padded with at least two square timbers 534 to support the stone block 100. During the stone cutting process, the stone cart frame 531, the square timbers 534, and the stone block 100 continue to rise along with the lifting platform assembly 51 until the diamond cutting wire cuts through the stone block 100 and into the square timbers 534. Two stone cart guardrails 532 are inserted on either side of the stone cart frame 531. Wooden wedges can be inserted between the stone cart guardrails 532 and the stone block 100 to reinforce the stone block 100 and alleviate the problem of the stone slab tipping over after cutting.

[0077] Furthermore, the block cart guardrail 532 can be configured to be adjustable in two positions to accommodate support and protection for stone blocks 100 of varying sizes during the cutting process. The block cart power assembly 533 can include a block cart motor 5331, a block cart reducer 5332, a block cart drive shaft 5333, a block cart drive gear 5334, and a block cart wheel 5335. The block cart motor 5331 is connected to the block cart reducer 5332, which is in turn connected to the block cart drive gear 5334 via the block cart drive shaft 5333, and further connected to the block cart wheel 5335 via the block cart gear. When controlling the movement of the block cart assembly 53, the block cart motor 5331 can be controlled to rotate forward and reverse to achieve forward and backward movement of the block cart assembly 53 in the second direction B, thereby enabling the loading and unloading functions of the block cart assembly 53.

[0078] During a stone cutting operation, the stone wire saw 1 first controls the block cart assembly 53 carrying the stone block 100 to move from the shuttle bus to the lifting platform 511. The block cart wheels 5335 move along the base guide rails 21 and the block cart guide rails 515 until the block cart frame 531 contacts the limit plate 512 on one side of the lifting platform 511. When the positional deviation between the positioning block 513 on the block cart assembly 53 and the positioning block 513 on the lifting platform 511 is within the allowable range, the stone wire saw 1 drives the lifting platform assembly 51 upward by lifting the drive assembly 52, thereby driving the block cart assembly 53 and the stone block 100 upward.

[0079] After completing preparatory work such as blade alignment, the stone wire saw 1 begins slicing. The servo motor 5211 in the lifting drive assembly 52 begins operating according to the set program. The servo motor 5211 in the lifting drive assembly 52 drives the screw rod 5222 upward through the coordination and transmission of the reducer 5212, the transmission shaft 5223, and the elevator 5221. The lifting platform assembly 51 connected to the screw rod 5222, the block trolley assembly 53 mounted on the lifting platform assembly 51, and the stone block 100 rise together with the screw rod 5222. After the screw rod 5222 raises the lifting platform 511 to a certain height, the V-shaped positioning blocks 513 welded to the block trolley frame 531 are aligned and adaptively positioned with the V-shaped positioning blocks 513 installed on the lifting platform 511, and the wheels 5335 of the block trolley, which were originally resting on the base guide rail 21, are suspended in the air. Under the action of its own gravity and the stone block 100, the block car assembly 53 presses the V-shaped positioning block 513 on the lifting platform 511. At this time, the block car motor 5331 can no longer control the movement of the block car assembly 53. The lifting drive assembly 52 is driven by the reducer 5212, the transmission shaft 5223, the worm gear transmission pair 5227 and other components, and continues to drive the screw to pull the lifting platform 511 to move upward smoothly until the diamond cutting wire cuts through the stone block 100.

[0080] After cutting is complete, the servo motor 5211 drives the rotating nut 5228 through the reducer 5212, the drive shaft 5223, the worm gear drive pair 5227, and other components, driving the reverse rotation of the rotating nut 5228. This in turn causes the screw 5222 to drive the lifting platform assembly 51, the block cart assembly 53, and the stone slab to descend. When the lifting platform 511 descends to the bottom zero position of the base assembly 3, the block cart wheels 5335 fall back onto the base guide rails 21, and the V-shaped positioning blocks 513 connected to the block cart frame 531 separate from the V-shaped positioning blocks 513 installed on the lifting platform 511. Finally, the stone wire saw 1 controls the block cart assembly 53 to move from the lifting platform 511 to the shuttle bus to complete the unloading of the cut stone slab.

[0081] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
