[0002] Diamond wire saws are widely used in mining, stone cutting and shaping, and the demolition of reinforced concrete structures. Compared to traditional construction methods, they offer numerous advantages, including high processing efficiency, low cost, flexible use, and static non-destructiveness. Diamond wire saws typically utilize rubber or plastic injection molding to secure diamond beads to the wire rope. Some versions incorporate springs between the beads for securement.

[0003] A diamond bead wire saw with publication number CN211030709U includes a steel wire rope and several bases. A spring is axially inserted into the base, and the spring is sleeved on the steel wire rope. The base is tightly connected to the steel wire rope by injection-molded rubber. Removable beads are sleeved on the outer periphery of the base. The beads include at least two shaft rings and fasteners. The shaft rings are tightly connected to the base by the fasteners. Injection molding material is injected between the base and the beads. The beads of the utility model are detachably connected to the base, which facilitates replacement and maintenance of the beads on the diamond bead wire saw, thereby improving the service life and processing efficiency of the diamond bead wire saw and reducing the production cost of the diamond bead wire saw.

[0004] Although the device is convenient for replacing and repairing the beads on the diamond bead wire saw, the device does not have an adjustment mechanism and cannot adjust the rope tension of the diamond bead wire.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] A device for automatically adjusting the tension of a diamond bead wire saw rope comprises an N-shaped mounting base 1. Slide grooves 11 are symmetrically provided at the front end of the N-shaped mounting base 1 near the left and right sides, for limiting the moving direction of a slider 37. Mounting frames 12 are symmetrically provided at the bottom of the N-shaped mounting base 1 near the left and right sides. A guide wheel 13 is rotatably connected to the rear surface of the inner wall of the mounting frame 12 via a bearing for mounting a diamond bead wire rope 16.

[0030] Specifically, a driving motor 14 is fixedly connected to the front surface of the inner wall of the n-type mounting seat 1 by bolts to drive the driving wheel 15 to rotate. The output shaft of the driving motor 14 is coaxially connected to the driving wheel 15 to drive the diamond bead rope 16 to rotate.

[0031] Specifically, a diamond beaded rope 16 is wound around the driving wheel 15 for cutting a workpiece. The diamond beaded rope 16 is wound around the driving wheel 15 , the auxiliary wheel 23 , the tensioning wheel 38 and the guide wheel 13 .

[0032] As a preferred embodiment of this invention, a first adjustment mechanism 2 is symmetrically provided near the left and right sides of the top of the N-type mounting seat 1. The first adjustment mechanism 2 includes a cylinder 21, which is fixedly connected to the top of the N-type mounting seat 1 by bolts to drive the N-type moving frame 22 to move.

[0033] Specifically, the piston rod end of the cylinder 21 passes through the top of the N-shaped mounting seat 1 and is fixedly connected to the N-shaped moving frame 22 by bolts, which is used to drive the auxiliary wheel 23 to rotate. The rear surface of the inner wall of the N-shaped moving frame 22 is rotatably connected to the auxiliary wheel 23 through a bearing.

[0034] Specifically, a mounting plate 24 is welded and fixed to one end of the n-type moving frame 22 away from the driving wheel 15, which is used to drive the scale 25 to move. The top of the mounting plate 24 is fixedly connected to the scale 25 by bolts. The top of the scale 25 passes through the top of the n-type mounting seat 1 and is slidably connected to the n-type mounting seat 1.

[0035] Specifically, first scale grooves 26 are provided on the outer circumferential wall of the scale 25 . The first scale grooves 26 are evenly spaced and arranged to facilitate users to understand the height of the auxiliary wheels 23 .

[0036] Furthermore, a second adjustment mechanism 3 is provided on the front side of the N-type mounting seat 1. The second adjustment mechanism 3 includes an adjustment motor 31. The adjustment motor 31 is fixedly connected to the front surface of the N-type mounting seat 1 by bolts to drive the bidirectional threaded rod 32 to rotate.

[0037] Specifically, the output shaft of the adjustment motor 31 is coaxially connected to the bidirectional threaded rod 32, and the bidirectional threaded rod 32 is symmetrically provided with threads with opposite thread directions near the left and right sides, so that when the bidirectional threaded rod 32 rotates, the two movable plates 33 move in opposite directions.

[0038] Specifically, the two-way threaded rod 32 is symmetrically threaded with movable plates 33 near the left and right sides to drive the slider 37 to move.

[0039] Specifically, a limit rod 34 is provided above the bidirectional threaded rod 32 to limit the moving direction of the movable plate 33. A plurality of second scale grooves 35 are provided on the circumferential outer wall of the limit rod 34. The second scale grooves 35 are arranged at uniform intervals to facilitate users to observe the distance between the two movable plates 33.

[0040] Specifically, the left and right ends of the limiting rod 34 respectively pass through the top of the two movable plates 33 and are fixedly connected to the fixing plate 36 by bolts. The rear end of the fixing plate 36 is fixedly connected to the front end of the N-shaped mounting seat 1 by bolts for installing the limiting rod 34.

[0041] Specifically, the rear end of the movable plate 33 is fixedly connected to a slider 37 by bolts, which is used to drive the tensioning wheel 38 to move. The slider 37 is slidably connected to the inner wall of the slide groove 11 corresponding to its position.

[0042] It is worth mentioning that the structure and working principle of the diamond bead rope 16 involved in this embodiment are well known to those skilled in the art and will not be elaborated here.

[0043] During specific use, when the tension of the diamond bead rope 16 needs to be increased, the user first controls the piston rods of the two cylinders 21 to extend, thereby driving the two N-shaped moving frames 22 to move downward, thereby driving the two auxiliary wheels 23 to move downward, thereby increasing the tension of the diamond bead rope 16;

[0044] During this process, the two N-shaped moving frames 22 respectively drive the two mounting plates 24 to move downward, thereby respectively driving the two scales 25 to move downward. The heights of the two auxiliary wheels 23 can be determined by the first scale grooves 26 on the two scales 25 that are on the same level as the top of the N-shaped mounting base 1. When the two auxiliary wheels 23 reach the specified height, the extension of the piston rods of the two cylinders 21 is stopped.

[0045] The user then turns on the adjusting motor 31, and the adjusting motor 31 drives the bidirectional threaded rod 32 to rotate, thereby driving the two movable plates 33 to move away from the driving wheel 15, thereby driving the two sliders 37 to move away from the driving wheel 15, thereby driving the two tensioning wheels 38 to move away from the driving wheel 15. When the distance between the two second scale grooves 35, which are respectively located in the same vertical plane as the vertical plane where the inner surfaces of the two movable plates 33 are located, reaches the specified distance, the distance between the two tensioning wheels 38 reaches the specified distance, and the tensioning force of the diamond bead rope 16 reaches the specified tensioning force, the adjusting motor 31 can be turned off.

[0046] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
