Description

Technical Field

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

[0002] Wire saws typically consist of a cutting chamber assembly and a lifting assembly. The lifting assembly lifts the stone block into the cutting chamber of the cutting chamber assembly, where the cutting chamber assembly's actuators cut the stone block. However, due to the weight of both the lifting assembly and the stone block, the lifting drive force of the lifting assembly may be insufficient. Alternatively, due to structural defects in the lifting assembly itself, or because vibrations from other components of the wire saw interfere with the lifting drive process, the lifting assembly is prone to swaying and tilting when lifting and lowering the stone block, thereby hindering the lifting of the stone block.

[0003] Therefore, how to design a new type of lifting assembly and stone wire cutting machine that can effectively position the stone block when the lifting assembly drives it to lift and lower it, offset the deformation as much as possible, reduce the shaking amplitude, and ultimately improve the smoothness and stability of the lifting assembly driving the stone block to lift and lower it has become a topic that urgently needs to be studied in the field of stone cutting equipment. Utility Model Content

[0004] The purpose of this application is to provide a lifting assembly and a stone wire cutting machine, which can alleviate the problems of shaking and jamming when the lifting assembly drives the stone blocks to rise and fall, and improve the smoothness and stability of the lifting assembly driving the stone to rise and fall.

[0005] The embodiment of the present application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a lifting assembly for use on a wire saw. The lifting assembly comprises a lifting platform, at least one lifting drive assembly, at least one V-shaped guide rail assembly, and at least one planar guide rail assembly. The lifting platform is configured to support rough stone material; the lifting drive assembly is connected to the lifting platform and configured to drive the lifting platform upward and downward; the at least one V-shaped guide rail assembly and the at least one planar guide rail assembly are disposed on the same side of the lifting platform; and the V-shaped guide rail assembly and / or the planar guide rail assembly include a lubrication structure configured to accommodate lubricating grease.

[0007] In the above technical solution, the lifting assembly drives the lifting platform and the stone to perform lifting movements through the lifting drive assembly. During the lifting process, both the planar guide rail assembly and the V-shaped guide rail assembly can provide guidance for the lifting movement of the lifting platform, making the lifting of the lifting platform more stable and reliable; the V-shaped guide rail assembly limits the lifting platform, which can improve the shaking of the lifting platform during the lifting process; the planar guide rail assembly can appropriately offset the deformation of the lifting assembly caused by vibration and other factors during the stone cutting process; the guide rail assembly cooperates with the lubrication structure to reduce friction, which can further alleviate the lifting jam problem. The embodiment of the present application effectively improves the stability and smoothness of the lifting platform.

[0008] In combination with the technical solution provided in the first aspect above, in some embodiments, each V-shaped guide rail assembly includes a V-shaped guide rail and a V-shaped slide rail that cooperate with each other, and each plane guide rail assembly includes a plane guide rail and a plane slide rail that cooperate with each other; each V-shaped slide rail and each plane slide rail are connected to the lifting platform, and each V-shaped guide rail and each plane guide rail extend along the lifting direction of the lifting platform and are arranged on at least one side of the lifting platform; the lubrication structure includes a grease lubrication groove, and the grease lubrication groove is provided on the guide mating surface of the V-shaped slide rail and / or the plane slide rail. In the above technical solution, the guide rail assembly stores lubricating grease through the grease lubrication groove, and guides the lubricating grease to flow and cover the guide mating surface between the slide rails, so that the slide rails slide more smoothly on the guide rails.

[0009] In combination with the technical solution provided in the first aspect above, in some embodiments, the lubrication structure further includes an oil filling port, an oil channel, and an oil outlet. The oil channel is provided inside the V-shaped slide rail and / or the planar slide rail, and the oil filling port is provided on the side wall of the V-shaped slide rail and / or the planar slide rail. The oil filling port is connected to the oil outlet through the oil channel, and the oil outlet is connected to the grease lubrication groove. In the above technical solution, the lubrication structure, through the provision of the oil filling port and the oil channel, allows the guide mating surface to be continuously replenished with lubricating grease through an external oil supply when the slide rail slides on the guide rail, thereby extending the service life of the guide rail assembly and improving the stability and reliability of the lifting assembly in driving the stone to be lifted and lowered.

[0010] In combination with the technical solution provided in the first aspect above, in some embodiments, the lifting assembly further includes at least one tensioner, each tensioner including a cylinder, a core shaft, a tensioning rod and a disc spring. The interior of the cylinder has a receiving hole that passes through both ends of the cylinder; one end of the core shaft is movably disposed in the receiving hole, and the core shaft is located at one end of the receiving hole, and the other end of the core shaft is connected to a V-shaped slide rail or a flat slide rail; one end of the tensioning rod is movably disposed in the receiving hole, and the tensioning rod is located at the other end of the receiving hole; the disc spring is disposed in the receiving hole and abuts between the core shaft and the tensioning rod. In the above technical solution, the tensioning rod that moves toward the core shaft can push the core shaft to move through the disc spring, thereby adjusting the clamping force between the slide rail and the guide rail to offset deformation or eliminate swinging as much as possible.

[0011] In conjunction with the technical solution provided in the first aspect above, in some embodiments, the tensioner further includes at least one sealing ring, each of which is disposed around the outer circumference of the core shaft and positioned between the core shaft and the barrel. In this technical solution, the sealing rings reduce the likelihood of water and dust ingress into the side of the barrel where the core shaft is located during stone cutting, thereby improving the tensioner's usability and extending its service life.

[0012] In conjunction with the technical solution provided in the first aspect above, in some embodiments, the tensioner further includes a protective sleeve, which is installed on the side of the cylinder where the tensioning rod is connected and extends over the outside of the tensioning rod. In this technical solution, the protective sleeve reduces the likelihood of water and dust ingress to the side of the cylinder where the tensioning rod is located during stone cutting, thereby improving the tensioner's usability and extending its service life.

[0013] In conjunction with the technical solution provided in the first aspect above, in some embodiments, the cylinder is connected to the lifting platform, and the lifting assembly further includes a protective cover plate connected to the lifting platform and disposed on top of the tensioner. In this technical solution, the installation of the protective cover plate on top of the connection between the tensioner and the lifting platform can alleviate the problem of water and dust ingress into the tensioner during stone cutting, thereby improving the quality of the tensioner and extending its service life.

[0014] In conjunction with the technical solution provided in the first aspect above, in some embodiments, a lifting drive assembly is provided on opposite sides of the lifting platform along the first direction, and a V-shaped guide rail assembly and a planar guide rail assembly are provided on the same side of the lifting platform along the first direction. In the above technical solution, the limiting direction of the V-shaped guide rail assembly and the offset deformation direction of the planar guide rail assembly are both aligned with the layout direction of the two lifting drive assemblies. This can alleviate the problems of the lifting platform shaking and stone lifting jamming caused by inconsistent drive strokes of multiple lifting drive assemblies, thereby improving the lifting accuracy and lifting stability of the lifting assembly.

[0015] In conjunction with the technical solution provided in the first aspect above, in some embodiments, a lifting drive assembly is connected to each of two opposite sides of the lifting platform along the first direction, and the lifting assembly further includes a limit plate, which is connected to one side of the lifting platform, and the limit blocking direction of the limit plate is perpendicular to the first direction. In the above technical solution, the lifting platform enables the rough stone car assembly to be initially positioned when moving on the lifting platform through the provision of the limit plate, thereby improving the positioning efficiency of the rough stone car assembly on the lifting platform; the limit blocking direction is perpendicular to the layout direction of the lifting drive assembly, which can reduce the probability of lateral deviation of the rough stone car assembly and further improve the stability of the lifting platform in carrying and lifting stone rough stone.

[0032] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0033] 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 stone block lift opening 301 for lifting and lowering a stone block 100. The cutting chamber assembly 4 is located on top of the base assembly 3, and the lifting assembly 5 is used to drive the stone block 100 up and down. When the lifting assembly 5 drives the stone block 100 up through the stone block lift 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 block 100 when in operation.

[0034] 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.

[0035] 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.

[0036] 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 2As shown, the lifting assembly 5 includes a block car assembly 53, a lifting platform assembly 51, and at least one lifting drive assembly 52. Specifically, the lifting platform assembly 51 includes a lifting platform 511, which is disposed inside the base assembly 3; a lifting drive assembly 52 is disposed on the base assembly 3 and connected to the lifting platform 511. The lifting drive assembly 52 is used to drive the lifting platform 511 to move up and down relative to the base assembly 3. The lifting platform 511 is used to carry the block car assembly 53 and the stone block 100.

[0037] In the above technical solution, the lifting drive assembly 52 is installed 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 vibration caused by the high-speed rotation of the main roller in the cutting chamber assembly 4, and the negative impact on the lifting platform 511 driving the stone block 100 to lift smoothly, effectively improving the stability of the lifting platform 511 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.

[0038] See Figure 3 , 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 2 、 Figure 3 As 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.

[0039] 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 walls of each column 31 adjacent to the lifting space 300 can be used to install the guide rails in the guide rail assembly; each column 31 can also be used to install other components, such as the second-floor working platform pillars.

[0040] 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 .

[0041] In some embodiments, the base assembly 3 may further include two base connecting beams 323, the extension directions of the base connecting beams 323 and the transverse connecting beams 321 are parallel to each other, each base connecting beam 323 extends in the first direction A, and the two ends of each base connecting beam 323 are respectively connected to the bottom ends of two adjacent columns 31.

[0042] 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 support structure to stably and reliably position and support components such as the cutting chamber assembly 4 and the lifting assembly 5. In this embodiment of the present application, the first direction A can refer to the layout direction of the multiple lifting drive assemblies 52 on the lifting platform 511. The first direction A can also refer to the extension direction of the transverse connecting beams 321 of the base assembly 3. The second direction B is perpendicular to the first direction A.

[0043] See Figure 4 , Figure 4 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 4 As shown, a lifting drive assembly 52 is provided on each side of the lifting platform 511 along the first direction A. Each lifting drive assembly 52 includes a drive unit 521 and two transmission units 522. Within the same lifting drive assembly 52 on the same side of the lifting platform assembly 51, the two transmission units 522 are symmetrically arranged at either end of the drive unit 521 and are in transmission connection with the drive unit 521.

[0044] 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 511 to rise and fall.

[0045] In some embodiments, a 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 two transmission units 522; the servo motor 5211 and the reducer 5212 are fixed to a longitudinal connecting beam 322. Each transmission unit 522 includes a screw rod 5222 and an elevator 5221, which is fixed to the top of the column 31 via a connecting ring. The elevators 5221 corresponding to the two transmission units 522 are respectively arranged at both ends of a longitudinal connecting beam 322, and the elevators 5221 are connected to the output shaft of the reducer 5212 via a transmission shaft 5223; one end of the screw rod 5222 passes through the elevator 5221 along the lifting direction C of the lifting platform 511 and is connected to the lifting platform 511 in the lifting space 300.

[0046] 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 screw rods 5222 of the four transmission units 522 are fixedly connected to the four corners of the lifting platform 511, thereby jointly driving the lifting platform 511 and the stone block 100 to move up and down. In the above technical solution, multiple screw rods 5222 can be arranged around the lifting platform 511, and each screw rod 5222 is arranged perpendicular to the top surface of the lifting platform 511 at each corner of the lifting platform 511, thereby improving the lifting stability of the lifting platform 511.

[0047] 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.

[0048] See Figures 5 and 6 , Figure 5 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 6 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 6 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 disposed on the same side of the lifting platform 511 .

[0049] Furthermore, the lifting assembly 5 may include two V-shaped guide rail assemblies 54 and two planar guide rail assemblies 55. A V-shaped guide rail assembly 54 is provided on each side of the lifting platform 511 along the second direction B, and a planar guide rail assembly 55 is provided on each side of the lifting platform 511. A V-shaped guide rail assembly 54 and a planar guide rail assembly 55 are provided at opposite ends of the same side of the lifting platform 511 along the first direction A (near the corners of the lifting platform 511), and the line connecting the two V-shaped guide rail assemblies 54 and the line connecting the two planar guide rail assemblies 55 can be parallel to the second direction B.

[0050] 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 connected to the same side of the lifting platform 511 along a first direction A. The line connecting the two V-shaped guide rails 541 and the line connecting the two planar guide rails 551 can both be parallel to a second direction B. The two V-shaped guide rails 542 and the two planar guide rails 552 extend along the lifting direction C of the lifting platform 511 and are respectively connected to the side walls of each column 31 of the base assembly 3.

[0051] In some embodiments, the base assembly 3 further includes an extension bracket 36, one of 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. The mounting surface 310 of the planar guide rail 552 or the V-shaped guide rail 542 on each column 31 is the sidewall surface adjacent to the column 31 and the lifting platform 511. The layout orientation and spacing 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 of each planar slide rail 551 and each V-shaped slide rail 541 on the lifting platform 511, thereby achieving a one-to-one fit between the planar slide rail 551 and the planar guide rail 552, and between the V-shaped slide rail 541 and the V-shaped guide rail 542, thereby effectively guiding the lifting and lowering motion of the lifting platform 511.

[0052] 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 and lowering movement of the lifting platform 511, making the lifting and lowering of the lifting platform 511 more stable and reliable. Among them, 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 improve the situation where the lifting platform 511 shakes left and right along 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 improve the situation where the lifting platform 511 shakes back and forth along 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 lifting assembly 5 along the first direction A due to factors such as vibration during the stone cutting process. The embodiment of the present application enables the planar slide rail 551 to slide smoothly on the planar guide rail 552, and enables the V-shaped slide rail 541 to slide smoothly on the V-shaped guide rail 542, reducing the probability that the lifting platform 511 cannot continue to rise and fall due to shaking and jamming, and improving the stability and smoothness of the lifting platform 511.

[0053] In the above technical solution, the limiting direction of the V-shaped guide rail assembly 54 and the offsetting deformation direction of the planar guide rail assembly 55 are the same as the layout direction of the two lifting drive assemblies 52 on the lifting platform 511, which can alleviate the problem of the lifting platform 511 shaking along the first direction A and the lifting platform 511 being stuck due to the inconsistent driving stroke of the lifting drive assembly 52, thereby improving the lifting accuracy and lifting stability of the lifting assembly 5.

[0054] In some embodiments, the V-shaped guide rail assembly 54 and / or the plane guide rail assembly 55 include a lubrication structure 57, and the lubrication structure 57 is used to accommodate lubricating grease. In the embodiment of the present application, the lubrication structure 57 can be provided only on the V-shaped slide rail 541 or the V-shaped guide rail 542 of at least one V-shaped guide rail assembly 54; the lubrication structure 57 can also be provided only on the plane slide rail 551 or the plane guide rail 552 of at least one plane guide rail assembly 55; the V-shaped guide rail assembly 54 and the plane guide rail assembly 55 can also be provided with a lubrication structure 57. In the above technical solution, the guide rail assembly cooperates with the setting of the lubrication structure 57, so that the friction between the slide rails and the guide rails can be reduced by lubricating grease, so as to alleviate the problem of the lifting platform 511 being stuck when lifting, thereby effectively improving the stability and smoothness of the lifting platform 511.

[0055] This embodiment of the application takes the planar slide rail 551 as an example to introduce the specific structural features of the lubrication structure 57 in detail. Figure 7 , Figure 7 FIG. 5 is a schematic diagram of the overall structure of a planar slide rail 551 according to an embodiment of the present application. Figure 7As shown, each planar slide rail 551 includes a planar slide rail base 5511 and a planar slide rail lining 5512. The planar slide rail lining 5512 is connected to one side of the planar slide rail base 5511. The planar slide rail 551 cooperates with the planar guide rail 552 through the planar slide rail lining 5512 and slides relative to each other.

[0056] In some embodiments, the lubrication structure 57 includes a grease lubrication groove 571, which is provided on the guide mating surface 5510 of the V-shaped slide rail 541 and / or the flat slide rail 551. Figure 7 As shown, the grease lubrication groove 571 is provided on the planar slide rail liner 5512 and is located on the guide mating surface 5510 where the planar slide rail liner 5512 and the planar guide rail 552 slide together. Specifically, the grease lubrication groove 571 can extend in various shapes and be evenly distributed on the guide mating surface 5510, such as a continuous I-shape or a continuous square shape. In the above technical solution, the guide rail assembly stores lubricating grease through the grease lubrication groove 571, and guides the lubricating grease to flow and cover the guide mating surface 5510 between the slide rail and the guide rail, making the slide rail slide more smoothly on the guide rail.

[0057] In some embodiments, the lubrication structure 57 further includes an oil filling port 573, an oil channel and an oil outlet 572. The oil channel is provided inside the V-shaped slide rail 541 and / or the plane slide rail 551, and the oil filling port 573 is provided on the side wall of the V-shaped slide rail 541 and / or the plane slide rail 551. The oil filling port 573 is connected to the oil outlet 572 through the oil channel, and the oil outlet 572 is connected to the grease lubrication groove 571. Figure 7 As shown, the oil filling port 573 is provided on the side wall of the planar slide rail base 5511, and the oil filling port 573 can be connected to the external lubricating oil delivery pipeline; an oil channel (not shown in the figure) is provided between the planar slide rail base 5511 and the planar slide rail lining 5512, and the oil filling port 573 is connected to the oil channel; the oil outlet 572 is provided in the grease lubrication groove 571 and flows with the oil channel.

[0058] Furthermore, the oil outlet 572 can be located at the center of the guide mating surface 5510, or multiple oil outlets 572 can be evenly distributed within the grease lubrication groove 571. In the above technical solution, the lubrication structure 57, through the arrangement of the oil filling port 573, the oil outlet 572, and the oil channel, allows the guide mating surface 5510 to be continuously and evenly replenished with lubricating grease through external oil supply as the slide rail slides on the guide rail, thereby extending the service life of the guide rail assembly and improving the stability and reliability of the lifting assembly 5 in driving the stone to be lifted.

[0059] See Figure 8 , Figure 8 This is a schematic diagram of the overall structure of the tensioner 56 shown in one embodiment of the present application. Figures 5 to 8As shown, the lifting assembly 5 also includes at least one tensioner 56, a tensioner 56 is connected to the side of a planar slide rail 551 away from the planar guide rail 552, or a tensioner 56 is connected to the side of a V-shaped slide rail 541 away from the V-shaped guide rail 542, and the tensioner 56 is used to adjust the gap or pressure between the slide rail and the guide rail so that the V-shaped slide rail 541 or the planar slide rail 551 can fit tightly with the corresponding V-shaped guide rail 542 or the planar guide rail 552, thereby improving the guiding stability of the lifting platform 511 during lifting and lowering movement.

[0060] Specifically, the tensioner 56 comprises a cylinder 561, a core shaft 562, a tensioning rod 563, and a disc spring 564. The cylinder 561 is connected to the lifting platform 511 and has a receiving hole 560 extending through both ends of the cylinder 561. One end of the core shaft 562 is movably disposed within the receiving hole 560 and is located at one end of the receiving hole 560. The other end of the core shaft 562 is connected to a V-shaped slide rail 541 or a flat slide rail 551. One end of the tensioning rod 563 is movably disposed within the receiving hole 560 and is located at the other end of the receiving hole 560. The disc spring 564 is disposed within the receiving hole 560 and abuts between the core shaft 562 and the tensioning rod 563. Furthermore, one end of the tension rod 563 can be connected to the inner wall of the accommodating through hole 560 through a threaded structure, so that the tension rod 563 can be screwed in or out relative to the cylinder 561.

[0061] In an embodiment of the present application, when adjusting the pressure between the planar slide rail 551 and the planar guide rail 552, or when adjusting the pressure between the V-shaped slide rail 541 and the V-shaped guide rail 542, it is only necessary to push / pull or rotate the tensioning rod 563 in the specified direction, and the tensioning rod 563 will further extend into or exit the accommodating through hole 560, and transmit the increased or decreased corresponding thrust to the core shaft 562 through the disc spring 564, thereby adjusting the clamping force between the slide rail connected to the core shaft 562 and the corresponding guide rail to offset deformation or eliminate swinging.

[0062] In some embodiments, the tensioner 56 further includes at least one layer of sealing ring 565, each sealing ring 565 is sleeved on the outer periphery of the core shaft 562 and is disposed between the core shaft 562 and the cylinder 561. Figure 8 For example, two sealing rings 565 are disposed one after another in the two annular grooves in the receiving hole 560 along the axis of the cylinder 561, and both sealing rings 565 are sleeved around the outer circumference of the core shaft 562. In the above technical solution, the tensioner 56, through the sealing rings 565, reduces the possibility of water and dust entering the side of the cylinder 561 with the core shaft 562 during the stone cutting process, thereby improving the performance and extending the service life of the tensioner 56.

[0063] In some embodiments, the tensioner 56 further includes a protective sleeve 566, which is mounted on the side of the cylinder 561 where the tensioning rod 563 is connected, and is sleeved over the outside of the tensioning rod 563. Furthermore, the tensioning rod 563 can be connected to the inner wall of the protective sleeve 566 via a threaded structure, thereby enhancing the stability of the connection between the protective sleeve 566 and the cylinder 561 and reducing the probability of the protective sleeve 566 falling off. In the above technical solution, the provision of the protective sleeve 566 in the tensioner 56 reduces the probability of water and dust ingress during the stone cutting process on the side of the cylinder 561 where the tensioning rod 563 is located, thereby improving the quality of the tensioner 56 and extending its service life.

[0064] Please combine Figure 5 、 Figure 6 As shown, in some embodiments, the lifting assembly 5 further includes a protective cover 517, which is connected to the lifting platform 511 and disposed on top of the tensioner 56. Specifically, the cylinder 561 is fixedly connected to a partition on one side of the lifting platform 511. The other end of the core shaft 562 passes through the partition and connects to the V-shaped slide rail 541 or the flat slide rail 551. The protective cover 517 is disposed on top of the cylinder 561. In the above technical solution, the provision of the protective cover 517 on top of the connection between the tensioner 56 and the lifting platform 511 can alleviate the problem of water and dust ingress into the tensioner 56 during stone cutting, thereby improving the quality of the tensioner 56 and extending its service life.

[0065] See Figure 9 , Figure 9 This is a partial structural diagram of the block car assembly 53 moving on the lifting platform 511 according to an embodiment of the present application. Figures 2 to 9 As shown, the lifting assembly 5 also includes a limit plate 512. All limit plates 512 are connected to the same side of the lifting platform 511, and the limit blocking direction of the limit plates 512 is perpendicular to the layout direction of the multiple lifting drive assemblies 52 on the lifting platform 511. The limit plates 512 are used to limit the movement distance of the block car assembly 53, providing initial positioning for the block car assembly 53, and improving the positioning efficiency and accuracy of the block car assembly 53.

[0066] Specifically, the limit plate 512 may include a limit support 5121 and a buffer block 5122. The limit support 5121 is fixed to the lifting platform 511, and the buffer block 5122 is connected to the side of the limit support 5121 near the center of the lifting platform 511. The buffer block 5122 may be a polyurethane buffer block. After the limit plate 512 is installed on the lifting platform 511, a small gap exists between it and the positioning block 513 to achieve adaptive positioning of the rough material vehicle assembly 53 on the lifting platform 511. The two limit plates 512 are arranged on the same side of the lifting platform 511 and are located along the second direction B on the side of the two positioning blocks 513 away from the center of the lifting platform 511.

[0067] In the above technical solution, the lifting platform 511 is provided with a limit plate 512, so that the block car assembly 53 can be initially positioned when moving on the lifting platform 511, thereby improving the positioning efficiency of the block car assembly 53 on the lifting platform 511; the limit blocking direction is perpendicular to the layout direction of the lifting drive assembly 52, which can reduce the probability of lateral deviation of the block car assembly 53, and further improve the stability of the lifting platform 511 in carrying the stone block 100.

[0068] Please combine Figures 2 to 9 As shown, two lifting drive assemblies 52 are arranged on either side of the lifting platform assembly 51 along a first direction A. This first direction A is perpendicular to the loading and unloading direction of the block cart assembly 53. This allows the stone block 100 mounted on the block cart frame 531 to be blocked by the block cart guardrail 532 when the lifting platform assembly 51 is tilted to one side, preventing it from sliding sideways. This improves the smoothness and reliability of the lifting assembly 5 in raising and lowering the stone block 100, enhancing the stability of the cutting of the stone block 100.

[0069] In some embodiments, the lifting assembly 5 may further include at least one positioning block 513 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.

[0070] For example, 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 located 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. In the above technical solution, the use of a split-type positioning block 513 is more conducive to fit and alignment, resulting in a more excellent load-bearing function, and can effectively improve the accuracy of positioning and loading stability of the rough material cart assembly 53 on the lifting platform 511. In addition, the split-type V-shaped positioning block 513 has a lower replacement cost after wear, and its practicality is higher.

[0071] Please combine Figure 6 、 Figure 9As shown, 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, so that the rough material car component 53 can continue to move on the lifting platform 511; when the lifting platform 511 is lifted to a certain height in the lifting space 300, the rough material car wheels originally falling on the basic guide rail 21 are suspended in the air, and the lifting platform 511 cooperates to support the rough material car component 53 through the positioning block 513 and restrict the rough material car component 53 from continuing to move.

[0072] 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 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 can drive the lifting platform assembly 51 to rise by lifting the drive assembly 52, thereby driving the block cart assembly 53 and the stone block 100 to rise.

[0073] 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 drives the screw 5222 upward, and the lifting platform 511 connected to the screw 5222, as well as the block trolley assembly 53 and the stone block 100 mounted on the lifting platform 511, rise along with the screw 5222. After the screw 5222 raises the lifting platform 511 to a certain height, the V-shaped positioning blocks 513 welded to the block trolley frame 531 mate with the V-shaped positioning blocks 513 installed on the lifting platform 511 and are adaptively positioned. The wheels of the block trolley, which were originally resting on the base guide rails 21, are suspended in the air. The block car assembly 53 presses the V-shaped positioning block 513 on the lifting platform 511 under the action of its own gravity and the stone block 100. At this time, the block car assembly 53 can no longer move through the block car wheels, and the lifting drive assembly 52 continues to pull the lifting platform 511 through the screw to move upward smoothly until the diamond cutting wire cuts through the stone block 100.

[0074] After cutting is complete, the servo motor 5211 drives the lifting platform 511, the block cart assembly 53, and the stone slab downward via the screw rod 5222. When the lifting platform 511 descends to the bottom zero position of the base assembly 3, the wheels of the block cart fall back onto the base rails 21, and the V-shaped positioning blocks 513 connected to the block cart frame 531 separate from the V-shaped positioning blocks 513 mounted 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.

[0075] 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.
