Description

Technical Field

[0001] This invention relates to the field of diamond bead saw protection, and more particularly to a device for preventing injury from broken diamond bead ropes. Background Technology

[0002] Diamond wire saws mainly consist of diamond wire ropes and wire saw drive wheels. The cutting tools used in diamond wire saws are diamond wire ropes, which are composed of steel wire ropes and diamond abrasive grains embedded in their surface. During the cutting process, the wire ropes rotate at high speed or reciprocate under the drive of the wire saw drive wheels. When the wire ropes come into contact with the stone, the diamond abrasive grains on the ropes will produce a grinding effect on the stone surface.

[0003] During the cutting process, the stone will also cause wear and tear on the diamond beaded cord. With increased use, the diamond beaded cord may break after wear. Figure 1 As shown, when the diamond beaded rope breaks, it will fly upwards and has a large whipping range. The equipment lacks a device to limit the whipping of the diamond beaded rope. Once the diamond beaded rope breaks, it may cause whipping damage to a large surrounding area. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the purpose of this invention is to provide a device to prevent damage from broken diamond bead ropes, addressing the current lack of protective devices to limit the impact of broken diamond bead ropes on diamond bead saws, which poses a significant safety hazard.

[0005] To address the problems of the prior art, the technical solution of the present invention is as follows:

[0006] A device for preventing injury from the breakage of a diamond beaded rope includes a frame extending in the direction of the diamond beaded rope, and an upper and a lower rope stopper. The upper and lower rope stopper are rotatably connected to the frame. The upper rope stopper presses down on the top of the diamond beaded rope, and the lower rope stopper abuts upward against the bottom of the diamond beaded rope.

[0007] Preferably, the pole frame includes a telescopic pole, a lifting frame, and a base. One end of the telescopic pole is connected to the base, and the other end of the telescopic pole extends in the direction of the diamond beaded rope. The upper rope guide wheel is rotatably connected to the telescopic pole. The lifting frame is perpendicular to the telescopic pole, and the lower rope guide wheel is rotatably connected to the lifting frame.

[0008] Preferably, there are two upper guide rope wheels and one lower guide rope wheel, with the lower guide rope wheel located between the two upper guide rope wheels.

[0009] Preferably, the telescopic rod includes a slidably inserted rod cylinder and a rod handle, two upper rope pulleys are respectively rotatably connected to the surfaces of the rod cylinder and the rod handle, and a first lead screw is rotatably provided at one end of the rod cylinder, which is threadedly connected to the rod handle.

[0010] Preferably, the lifting frame includes a vertical shell, and a slider is vertically and elastically slidably disposed inside the vertical shell by means of a spring, and the lower guide rope wheel is rotatably connected to the slider.

[0011] Preferably, a contact plate is slidably disposed inside the vertical shell, a spring is disposed between the slider and the contact plate, and a stud is threaded through the top of the vertical shell, the stud being rotatably connected to the contact plate.

[0012] Preferably, the lifting frame is slidably connected to the handle via a sliding sleeve. The surface of the lifting frame has a vertically extending groove, and a bearing seat is slidably arranged in the groove. Two connecting rods are symmetrically mounted on the bearing seat and are arranged in a figure-eight pattern to rotatably connect the cylinder and the handle respectively.

[0013] Preferably, the telescopic rod is rotatably connected to the base, a second lead screw is rotatably provided on the surface of the telescopic rod, the second lead screw is threadedly connected to a support, the support is rotatably connected to a support arm, and the other end of the support arm is rotatably connected to the base.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] 1. This invention features an upper stop pulley that presses down on the diamond beaded rope and a lower stop pulley that abuts against the diamond beaded rope. The lower stop pulley has an upward elastic displacement tendency. When the diamond beaded rope breaks, the upper stop pulley prevents the diamond beaded rope from flying backward, while the lower stop pulley moves upward rapidly and alternates with the upper stop pulley to pull the diamond beaded rope. This greatly reduces the length of the diamond beaded rope flyaway and the coverage area of ​​the diamond beaded rope flyaway, thereby improving safety.

[0016] 2. This invention controls the extension and retraction of the telescopic rod to adjust the separation distance and extension position of the two upper stop rope wheels. The vertical shell is pushed to move along the rod handle by the figure-eight distributed connecting rod, so that the lower stop rope wheel is always kept in the middle position of the two upper stop rope wheels, ensuring that the lower stop rope wheel and the upper stop rope wheel are evenly and alternately pulled to pull the diamond bead rope.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] The device for preventing injury from broken diamond beaded rope uses an upper stop pulley 4 and a lower stop pulley 5 to block the broken diamond beaded rope fragments, reducing the fragmentation range. The upper stop pulley 4 and the lower stop pulley 5 are connected to the wire saw machine via a rod frame. The specific structure is as follows:

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, the frame consists of a telescopic rod, a lifting frame, and a base 3. The base 3 is bolted to the edge of the drive wheel of the wire saw. The telescopic rod extends along the upper transmission part of the diamond beaded rope. The end of the telescopic rod is connected to the base 3. The lifting frame is installed in the middle of the telescopic rod and is perpendicular to the telescopic rod. Two upper rope guide wheels 4 are rotatably installed on the surface of the telescopic rod. The lifting frame includes a vertical shell 2. A slider is vertically and elastically slidably installed inside the vertical shell 2 by a spring. A lower rope guide wheel 5 is rotatably installed on the surface of the slider. The lower rope guide wheel 5 is located between the two upper rope guide wheels 4.

[0026] The upper stop pulley 4 presses down on the diamond beaded rope, while the lower stop pulley 5 touches the bottom of the diamond beaded rope. The wire saw wheel assembly drives the diamond beaded rope to transmit cutting through the stone. When the diamond beaded rope breaks, the upper stop pulley 4 prevents the diamond beaded rope from flying backward. At the same time, the slider is driven by the elastic force to move the lower stop pulley 5 upward quickly. The alternation of the lower stop pulley 5 and the upper stop pulley 4 is used to pull the diamond beaded rope, which greatly reduces the length of the diamond beaded rope and the coverage area of ​​the diamond beaded rope, thus improving safety.

[0027] like Figure 3As shown, a touch plate 22 is slidably arranged on the upper part of the vertical shell 2, and a spring is arranged between the slider and the touch plate 22. A stud 23 is threaded through the top of the vertical shell 2 and rotatably connected to the touch plate 22. The distance between the touch plate 22 and the slider is adjusted by rotating the stud 23, which is used to adjust the upward pull force of the slider.

[0028] like Figure 5 As shown, the telescopic pole includes a slidingly inserted pole tube 1 and a pole handle 11. Two upper rope guide wheels 4 are rotatably connected to the surfaces of the pole tube 1 and the pole handle 11, respectively. One end of the pole tube 1 extends inward and is rotatably provided with a first lead screw 12, which is threadedly connected to the pole handle 11.

[0029] The sliding extension length of the rod cylinder 1 and the rod handle 11 is adjusted by rotating the first lead screw 12, which is used to adjust the distance and extension distribution position of the two upper guide rope wheels 4, and to adaptively adjust the position that hinders the diamond bead rope missile according to the working extension state of the diamond bead rope.

[0030] When adjusting the distance between the two upper stop rope pulleys 4, the position of the lower stop rope pulley 5 needs to be adjusted simultaneously so that the lower stop rope pulley 5 is always in the middle of the two upper stop rope pulleys 4. This ensures that the lower stop rope pulley 5 and the upper stop rope pulleys 4 are evenly and alternately pulling the diamond bead rope. The specific operation is as follows:

[0031] like Figure 3 , Figure 4 As shown, a sliding sleeve 21 is fixed on the surface of the vertical shell 2. The sliding sleeve 21 is slidably connected to the handle 11. A vertically extending groove 61 is opened on the back of the vertical shell 2. A shaft seat is slidably installed in the groove 61. Two connecting rods 6 are coaxially rotatably connected to the shaft seat. The two connecting rods 6 are symmetrically distributed in a figure-eight pattern. The bottom ends of the two connecting rods 6 are rotatably connected to the rod cylinder 1 and the handle 11, respectively.

[0032] When the distance between the two upper rope pulleys 4 is adjusted by extending and retracting the control rod cylinder 1 and the rod handle 11, the distance between the connection points of the two connecting rods 6 and the rod cylinder 1 and the rod handle 11 changes synchronously, causing the angle of the coaxial hinge end of the two connecting rods 6 to change. The bearing seat slides adaptively in the slide groove 61, and the vertical shell 2 is pushed to slide along the rod handle 11, so that the lower rope pulley 5 is always located in the middle position of the two upper rope pulleys 4.

[0033] like Figure 4 As shown, the telescopic rod is rotatably connected to the base 3, and a second lead screw 72 is rotatably provided on the surface of the telescopic rod. The support 71 slides flatly on the surface of the telescopic rod, and the second lead screw 72 is threaded through the support 71. The support 71 is rotatably connected to the support arm 7, and the other end of the support arm 7 is rotatably connected to the base 3.

[0034] The rod cylinder 1, the support arm 7, and the base 3 form a triangular distribution. By rotating the second lead screw 72, the position of the support 71 is adjusted, which changes the upward angle of the rod cylinder 1. This is used to adjust the angle position of the upper rope wheel 4 and the lower rope wheel 5 relative to the diamond bead rope.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
