Description

Technical Field

[0001] This application relates to the field of stone wire saws, and in particular to a stone wire saw machine with a vertical structure and a double take-up and release system. Background Technology

[0002] Stone wire saws in related technologies typically have a wire feeding and take-up device on each of the back panels on both sides of the frame, forming a wire feeding and take-up system. This system is used to release new wire for cutting and collect damaged old wire. However, a single wire feeding and take-up system has a limited number of cutting wires and is not suitable for cutting large blocks of raw stone that consume a lot of wire. Summary of the Invention

[0003] In view of this, this application provides a stone wire saw with a vertical structure and a double take-up and release system, which is suitable for cutting large-sized blocks of stone.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A stone wire saw with a vertical structure and a double take-up and release system is characterized by: a column, a cutting assembly mounted on the column for cutting stone; the cutting assembly includes a cutting frame, two or more main guide wheels rotatably connected to the cutting frame, a rotary motor for driving the main guide wheels to rotate forward and backward, and two sets of take-up and release systems; each set of take-up and release systems includes two take-up and release assemblies mounted on the back plates on the left and right sides of the cutting frame, with two cutting lines wound around each main guide wheel to form two independent cutting mesh surfaces arranged in a front-to-back pattern; the two take-up and release assemblies of each set of take-up and release systems are respectively connected to the two ends of the corresponding cutting lines to control the take-up and release of the cutting lines respectively.

[0006] The stone wire saw with a vertical structure and a double take-up and release system described in this application can lay two rolls of wire at the same time by setting up two take-up and release systems simultaneously, resulting in a higher cutting capacity and making it suitable for cutting raw blocks with high wire consumption.

[0007] In some embodiments, the take-up and release assembly includes a take-up and release mechanism, a wire laying mechanism, a redirecting wheel, a tension mechanism, and a wire feeding / exit mechanism mounted on the back plate of the cutting frame. The take-up and release mechanism includes a take-up and release base fixedly mounted on the back plate, a bearing housing mounted in the take-up and release base, a take-up and release wheel fixedly connected to the mandrel in the bearing housing and vertically arranged, and a take-up and release motor connected to the other end of the bearing housing and located below the take-up and release base for driving the mandrel to rotate. The wire laying mechanism includes a wire laying wheel located next to the take-up and release wheel and capable of moving up and down, and a wire laying drive assembly for driving the wire laying wheel to move up and down. The redirecting wheel is located above the wire laying wheel and rotatably connected to the back plate, with its axis perpendicular to the back plate. The tension mechanism includes a tension wheel with its axis perpendicular to the back plate and a tension drive assembly for driving the tension wheel to deflect. The wire feeding / exit mechanism includes a wire feeding / exit wheel for controlling the position of the cutting wire entering and exiting. The cutting wire is sequentially connected to the take-up and release wheel, the wire laying wheel, the redirecting wheel, the tension wheel, and the wire feeding / exit wheel.

[0008] The cable take-up and release assembly features vertically positioned take-up and release reels, facilitating hoisting and installation while occupying minimal space on the back panel. This allows two take-up and release assemblies to be installed on the same back panel. Furthermore, the vertical arrangement of the take-up and release reels ensures better stress distribution in the bearing housing, eliminating cantilever torque. Additionally, the cable laying mechanism is also installed vertically, which, compared to a horizontal arrangement, prevents water accumulation.

[0009] In some embodiments, the cable drive assembly is a cable guide screw assembly mounted on a back plate and arranged vertically. The cable guide screw assembly is further provided with a second protective cover. The cable inlet and outlet mechanism also includes an inlet and outlet screw assembly mounted on the back plate for driving the inlet and outlet wheel to move back and forth. The inlet and outlet screw assembly is provided with a first protective cover.

[0010] In some embodiments, the tension drive assembly includes a tension base fixedly mounted on a back plate, a swing arm connected to a tension wheel, a tension motor mounted on the tension base for driving the swing arm's swaying motion, and two limiting blocks fixedly mounted on the tension base and located on the left and right sides of the swing arm.

[0011] In some embodiments, the cutting assembly is rotatably connected to the column via a pivot, and the column is also equipped with a swing mechanism for driving the cutting assembly to swing around the pivot; during the swinging process, the cutting assembly's cutting line performs a swing-type cut on the stone.

[0012] This embodiment employs a swaying motion of the cutting assembly driven by a swaying mechanism to achieve swaying cutting. This reduces the contact area between the cutting line and the stone, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone. Furthermore, the stone itself does not need to sway during the cutting process, preventing it from tipping over.

[0013] In some embodiments, the lower middle part of the cutting frame is rotatably connected to the column via a pivot. The swing mechanism includes two sets of hydraulic cylinders mounted on the column and located on both sides of the pivot. The extension rods of the hydraulic cylinders are hinged to the cutting frame. The two sets of hydraulic cylinders drive the cutting frame to swing around the pivot in a one-extension-one-retraction manner.

[0014] In some embodiments, the number of hydraulic cylinders is four, and they are located at the four corners of the cutting frame.

[0015] In some embodiments, the column is also connected to a lifting platform for lifting the stone and a lifting mechanism for driving the lifting platform to move up and down.

[0016] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0017] This stone wire saw features a vertical structure with a dual take-up and release system. By simultaneously setting up two take-up and release systems, two rolls of wire can be laid at the same time, resulting in a higher cutting capacity. It is suitable for cutting raw blocks with high wire consumption. Attached Figure Description

The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0025] See Figures 1 to 5 This application provides a stone wire saw with a vertical structure and a double take-up and release system, including a column 1 and a cutting assembly 4 mounted on the column 1 for cutting stone 7. The cutting assembly 4 includes a cutting frame 42, two or more main guide wheels 43 rotatably connected to the cutting frame 42, a rotary motor 44 for driving the main guide wheels 43 to rotate forward and backward, and two sets of take-up and release systems. Each set of take-up and release systems includes two take-up and release assemblies 45 respectively mounted on the back plates 451 on the left and right sides of the cutting frame 42. Two cutting lines 41 are wound around each main guide wheel 43 to form two independent cutting mesh surfaces 46 arranged in a front-to-back pattern. The two take-up and release assemblies 45 of each set of take-up and release systems are respectively connected to the two ends of the corresponding cutting lines 41 to control the take-up and release of the cutting lines 41 respectively.

[0026] This 7-wire stone saw can simultaneously lay two reels of wire by setting up two wire take-up and release systems, resulting in a higher cutting capacity of 41 wires and making it suitable for cutting raw blocks with high wire consumption.

[0027] Each take-up and release assembly 45 includes a take-up and release mechanism 452, a cable laying mechanism 453, a guide wheel 454, a tension mechanism 455, and a cable feeding / exit mechanism 456, all mounted on the back plate 451 of the cutting frame 42. The take-up and release mechanism 452 includes a take-up and release base 4521 fixedly mounted on the back plate 451, a bearing housing mounted in the take-up and release base 4521, a take-up and release wheel 4522 fixedly connected to the spindle in the bearing housing and vertically arranged, and a take-up and release motor 4523 connected to the other end of the bearing housing and located below the take-up and release base 4521 for driving the spindle rotation. The cable laying mechanism 453 includes a guide wheel 454 located beside the take-up and release wheel 4522. The system includes a vertically movable wire guide wheel 4531 and a wire guide drive assembly for driving the wire guide wheel 4531 to move vertically; a redirecting wheel 454 is disposed above the wire guide wheel 4531 and rotatably connected to the back plate 451 with its axis perpendicular to the back plate 451; a tension mechanism 455 includes a tension wheel 4551 with its axis perpendicular to the back plate 451 and a tension drive assembly for driving the tension wheel 4551 to deflect; a wire feeding / discharging mechanism 456 includes a wire feeding / discharging wheel for controlling the position of the cutting wire 41; the cutting wire 41 is sequentially connected to a take-up / release wheel 4522, a wire guide wheel 4531, a redirecting wheel 454, a tension wheel 4551, and a wire feeding / discharging wheel.

[0028] The take-up and release assembly 45 features a vertically positioned take-up and release reel 4522, facilitating hoisting and installation. It occupies minimal space on the back plate 451, allowing two take-up and release assemblies 45 to be installed on the same back plate 451. Furthermore, the vertical position of the take-up and release reel 4522 ensures good stress distribution in the bearing housing, eliminating cantilever torque. Additionally, the cable laying mechanism 453 is also installed vertically, which, compared to a horizontal arrangement, prevents water accumulation.

[0029] The cable routing drive assembly is a vertically arranged cable routing screw assembly mounted on the back plate 451. The cable routing screw assembly is also provided with a second protective cover 4533. The cable feeding and discharging mechanism 456 also includes a cable feeding and discharging screw assembly 4561 mounted on the back plate 451 for driving the cable feeding and discharging wheels to move back and forth. The cable feeding and discharging screw assembly 4561 is provided with a first protective cover 4562.

[0030] The tension drive assembly includes a tension base 4552 fixedly mounted on a back plate 451, a swing arm 4553 connected to a tension wheel 4551, a tension motor 4554 mounted on the tension base 4552 for driving the swing arm 4553 to swing, and two limiting blocks 4555 fixedly mounted on the tension base 4552 and located on the left and right sides of the swing arm 4553.

[0031] The cutting component 4 is rotatably connected to the column 1 via a rotating shaft 6. The column 1 is also equipped with a swing mechanism 5 for driving the cutting component 4 to swing around the rotating shaft 6. During the swinging process, the cutting component 4's cutting line 41 performs swing-type cutting on the stone 7.

[0032] This embodiment employs a swaying motion of the cutting component 4 driven by the swaying mechanism 5 to achieve swaying cutting. This reduces the contact area between the cutting line 41 and the stone 7, increases local pressure, improves cutting efficiency, and enables the cutting of hard stone 7. Furthermore, the stone 7 itself does not need to sway during the cutting process, thus preventing the stone 7 from tipping over.

[0033] The lower middle part of the cutting frame 42 is rotatably connected to the column 1 via a rotating shaft 6. The swing mechanism 5 includes two sets of hydraulic cylinders 51 mounted on the column 1 and located on both sides of the rotating shaft 6. The telescopic rods of the hydraulic cylinders 51 are hinged to the cutting frame 42. The two sets of hydraulic cylinders 51 drive the cutting frame 42 to swing around the rotating shaft 6 in a one-to-one extension and retraction manner.

[0034] The hydraulic cylinders 51 are four in number and are located at the four corners of the cutting frame 42.

[0035] The column 1 is also connected to a lifting platform 2 for lifting the stone 7 and a lifting mechanism 3 for driving the lifting platform 2 to move up and down.

[0036] The following is a brief description of the working process and usage of a stone wire saw with a vertical structure and a double take-up and release system, as described in the above embodiment:

[0037] Stone 7 moves onto lifting platform 2 along with the trolley. Lifting mechanism 3 drives lifting platform 2 to move upward continuously, thus moving stone 7 upward as well. The main drive wheel 43 of cutting assembly 4 rotates forward and backward under the drive of motor 44, causing cutting mesh 46 to back and forth saw stone 7. Cutting frame 42 swings forward and backward around shaft 6 under the drive of four hydraulic cylinders 51, performing oscillating cutting. During the cutting process, two wire take-up and unwinding systems work simultaneously. One take-up and unwinding assembly 45 continuously releases new cutting wire 41, while the other take-up and unwinding assembly 45 continuously collects old wire into a roll. After stone 7 is cut, cutting assembly 4 stops moving, and lifting platform 2 lowers and resets with stone 7.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
