Description

Technical Field

[0001] This invention relates to the field of concrete block cutting technology, and more particularly to a cutting device for producing concrete composite blocks. Background Technology

[0002] Concrete composite block cutting refers to the process of cutting concrete material into blocks of specific sizes and shapes. This cutting typically requires specialized concrete cutting equipment, such as wire cutting machines, concrete cutting machines, electric saws, or laser cutting machines.

[0003] Currently, wire cutting machines primarily cut concrete using the compressive force of a metal cutting wire. Operators typically adjust the wire tension to change this pressure, adapting to concrete blocks of varying hardness. However, for composite concrete blocks, which consist of layers of concrete and insulation with varying hardness, existing wire cutting machines only adjust the tension required for the harder concrete layer. When cutting the less hard insulation layer, the wire pressure is too high, causing excessive deformation, collapse, and adhesion of the insulation layer, thus affecting the overall cutting quality of the composite concrete block. Summary of the Invention

[0004] In order to overcome the shortcomings described in the background above, the present invention provides a cutting device for the production of concrete composite blocks.

[0005] Technical Solution: A cutting device for producing concrete composite blocks, comprising: a support frame, wherein an outer frame is slidably connected to the support frame, and an inner frame is slidably connected to the outer frame; the support frame is equipped with a driving mechanism for moving the outer frame and the inner frame; a cutting assembly, comprising several components, all disposed on the inner frame, for cutting materials, the cutting assembly comprising: two first U-shaped frames, respectively fixed to both sides of the inner frame, the first U-shaped frames being slidably connected to a first mounting box; two guide wheels, respectively rotatably connected to adjacent first mounting boxes, a cutting rope fixedly connected between the two guide wheels, a first transition groove provided on one side of each guide wheel, a first protrusion fixedly connected to the first U-shaped frame and sliding within the first transition groove, a first elastic element fixedly connected between the guide wheel and the first mounting box; and two first detection components, respectively disposed on adjacent first U-shaped frames, for detecting the resistance encountered by the guide wheels during movement.

[0006] Furthermore, the first detection component includes: two first T-shaped blocks, which are slidably connected to both sides of the first U-shaped frame respectively; a second elastic element is fixedly connected between the first T-shaped block and the first U-shaped frame; the guide wheel is fixedly connected to a first rotating shaft; and the first T-shaped block is rotatably connected to the first rotating shaft.

[0007] Furthermore, a circular groove is provided on the side of the guide wheel away from the first mounting box, and the end of the first transition groove away from the center of the guide wheel is connected to the circular groove. A one-way plate is rotatably connected at the connection between the circular groove and the first transition groove, and the one-way plate is used to limit the first protrusion.

[0008] Furthermore, it also includes: a compensation component, the same number as the cutting ropes, disposed on the inner frame, used to cut the material in place of the cutting ropes when the cutting ropes break. The compensation component includes: two sliding rods, slidably connected to both sides of the inner frame, each sliding rod being fixed to a second U-shaped frame, the second U-shaped frame having a second protruding post fixed to it, a second rotating shaft and a second mounting box slidably connected to the second U-shaped frame, the second rotating shaft being rotatably connected to a compensation wheel, and a third elastic element fixed between the second mounting box and the compensation wheel; a compensation rope, fixed between the two compensation wheels; two second detection components, disposed on adjacent second U-shaped frames, used to detect the resistance encountered when the compensation wheel moves; and two lifting components, disposed on adjacent sliding rods, used to adjust the height of the sliding rods.

[0009] Furthermore, the second detection component includes: two second T-shaped blocks, which are slidably connected to both sides of the second U-shaped frame, and both second T-shaped blocks are rotatably connected to the second rotating shaft. A fourth elastic element is fixed between the second T-shaped blocks and the second U-shaped frame.

[0010] Furthermore, a second transition groove is provided on the side of the compensation wheel away from the second mounting box, and the second protrusion slides within the second transition groove.

[0011] Furthermore, the lifting assembly includes: a rack fixedly connected to the sliding rod; a pressing plate fixedly connected to the sliding rod, with a fifth elastic element fixedly connected between the pressing plate and the inner frame; a transmission assembly disposed on the guide wheel for driving the rack to move; and a locking assembly disposed on the inner frame for locking the sliding rod.

[0012] Furthermore, the transmission assembly includes: a transmission gear rotatably connected to the guide wheel, the transmission gear being connected to the rack; and several limiting blocks, all slidably connected to the guide wheel, with a sixth elastic element fixedly connected between the guide wheel and the limiting blocks, the limiting blocks limiting the transmission gear.

[0013] Furthermore, both the transmission gear and the guide wheel are provided with circumferentially distributed blind holes, the cross-section of the limiting block is trapezoidal, the number of blind holes on the limiting block is the same as the number of blind holes on the guide wheel, and the limiting block is located in an adjacent blind hole on the guide wheel.

[0014] Furthermore, the locking component includes: a limiting shell fixedly connected to the inner frame, a locking block slidably connected to the limiting shell, the locking block being used to limit the compression plate, and a seventh elastic element fixedly connected between the locking block and the limiting shell.

[0015] The present invention has the following advantages: The present invention adjusts the position of the guide wheel and the tension of the guide wheel on the cutting rope by changing the resistance of the cutting rope. By adjusting the tension of the cutting rope, the tension of the cutting rope is changed for different parts of the concrete composite block with different hardness, thereby improving the stability of the cutting rope when cutting each layer of the concrete composite block, making the edges of the cut concrete block neater, and improving the cutting quality of the concrete block.

[0016] When the cutting rope breaks, the first protrusion slides into the circular groove and slides freely within it. The torque of the first elastic element allows the guide wheel to rotate freely, thereby winding the cutting rope. The cutting rope is then pulled out by the rotating guide wheels on both sides, ensuring that the broken cutting rope does not damage the cutting device or the concrete block. This reduces the impact on the surface flatness of the concrete block, ensures the continuous stability of the cutting operation, and reduces the scrap rate of the concrete block cutting.

[0017] During normal cutting, the compensating rope separates the areas where the concrete re-adhedes after being cut by the cutting rope, improving the flatness of the cut concrete surface and thus improving the cutting quality of the concrete blocks. After the cutting rope breaks, the compensating rope moves to the position where the cutting rope broke under the drive of the rack and replaces the cutting rope to continue cutting. This not only avoids the deviation in cutting trajectory caused by the replacement or repositioning of the cutting rope, but also reduces the losses caused by abnormal operating conditions of the equipment and maintains the stability of equipment operation.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: A cutting device for producing concrete composite blocks, such as... Figures 1-10 As shown, it includes: a support frame 1, with an outer frame 3 slidably connected to the support frame 1, and an inner frame 5 slidably connected to the outer frame 3. The support frame 1 is equipped with a drive mechanism for moving the outer frame 3 and the inner frame 5. A cutting assembly, having several components, is set on the inner frame 5 and is used for cutting materials. The cutting assembly includes: two first U-shaped frames 6, which are fixed to both sides of the inner frame 5 respectively. The first U-shaped frames 6 are slidably connected to a first mounting box 7. Two guide wheels 8 are rotatably connected to adjacent first mounting boxes 7 respectively. A cutting rope 80 is fixed between the two guide wheels 8. A first transition groove 10 is provided on one side of the guide wheel 8. A first protrusion 601 that slides within the first transition groove 10 is fixed to the first U-shaped frame 6. A first elastic element 9 is fixed between the guide wheel 8 and the first mounting box 7. Two first detection components are set on adjacent first U-shaped frames 6 respectively and are used to detect the resistance encountered by the guide wheels 8 when they move.

[0035] The above scheme proposes a method to change the tension of the cutting rope (80) and cut concrete composite blocks, aiming to improve the cutting quality and efficiency of the blocks. The material mentioned above refers to concrete composite blocks. The driving mechanism consists of a first driving module 2 and a second driving module 4. The first driving module 2 drives the outer frame 3 and its upper parts to move up and down, and the second driving module 4 drives the inner frame 5 and its upper parts to move left and right, reducing cutting resistance and distributing the cutting force more evenly across the cutting surface of the block, thus improving the quality of the cut blocks. A right-angle frame is installed on a U-shaped frame 6. The right-angle frame ensures that the cutting rope 80 remains horizontal and exerts an upward squeezing effect on the cutting rope 80. The cutting rope 80 is made of diamond wire, which maintains good cutting performance when cutting concrete composite blocks, resulting in a smoother cut surface. The first elastic element 9 is a coil spring, and it is initially in a charged state. The guide wheel 8 is rubber-coated to increase the friction between the guide wheel 8 and the cutting rope 80, preventing relative slippage between them. The distance between the first transition groove 10 and the center of the guide wheel 8 gradually decreases from top to bottom (e.g., ...). Figure 10 As shown, this is used to gradually slow down the increase in tension of the guide wheel 8, make the stress distribution inside the cutting rope 80 relatively uniform, and extend the service life of the cutting rope 80.

[0036] like Figure 6 , Figure 8 and Figure 9 As shown, the first detection component includes: two first T-shaped blocks 21, which are slidably connected to both sides of the first U-shaped frame 6 respectively; a second elastic element 22 is fixed between the first T-shaped block 21 and the first U-shaped frame 6; a guide wheel 8 is fixedly connected to a first rotating shaft 602; and the first T-shaped block 21 and the first rotating shaft 602 are rotatably connected.

[0037] The above proposes a method for detecting the movement resistance of the guide wheel 8. The degree of deformation of the second elastic element 22 reflects the magnitude of the resistance experienced by the guide wheel 8, thereby adjusting the tension of the guide wheel 8 on the cutting rope 80. The second elastic element 22 is a tension spring. Under the compression effect of the right-angle frame on the first U-shaped frame 6, the second elastic element 22 is initially in a stretched state, and the second elastic element 22 can be replaced according to the density changes of different concretes.

[0038] like Figure 6 , Figure 9 and Figure 10 As shown, a circular groove 41 is provided on the side of the guide wheel 8 away from the first mounting box 7. The end of the first transition groove 10 away from the center of the guide wheel 8 is connected to the circular groove 41. A one-way plate 42 is rotatably connected at the connection between the circular groove 41 and the first transition groove 10. The one-way plate 42 is used to limit the first protrusion 601.

[0039] The above proposes a method to rotate the guide wheel 8 when the cutting rope 80 is disconnected, so that the rotation of the guide wheel 8 drives the cutting rope 80 to be pulled away from the concrete composite block; the one-way plate 42 has a first torsion spring, which can control the one-way plate 42 to reset, and the one-way plate 42 can allow the first protrusion 601 to enter the circular groove 41 from the first transition groove 10, but cannot allow the first protrusion 601 to enter the first transition groove 10 through the circular groove 41.

[0040] When using this device to cut concrete composite blocks (hereinafter referred to as blocks), the worker first moves the block to the cutting area of ​​the device. Then, the worker activates the first drive module 2 and the second drive module 4. The first drive module 2 drives the outer frame 3 and its parts to descend, and the second drive module 4 drives the inner frame 5 to move left and right. The inner frame 5 drives all the first U-shaped frames 6 and their internal parts to move. During the descent of the outer frame 3 and its parts, the outer frame 3 drives the inner frame 5 to move downward, and the inner frame 5 drives all the first U-shaped frames 6 to move downward. The first U-shaped frames 6 drive the first T-shaped blocks 21 to move downward through the second elastic element 22. The first T-shaped blocks 21 drive the first mounting box 7 and the guide wheel 8 to move downward through the first rotating shaft 602. The mounting box 7 drives the first elastic element 9 to move downwards, and the guide wheel 8 drives the cutting rope 80 to move downwards. The cutting rope 80 moves downwards and squeezes the block. The block is divided into the required size by the squeezing of the block by the cutting rope 80. When the cutting rope 80 passes through the block and moves downwards to the limit position, the cutting is completed. After the cutting is completed, the worker closes the first drive module 2 and the second drive module 4 and transports the cut block to the subsequent processing area (forming). After the block is transported out of the cutting area of ​​this device, the worker starts the first drive module 2 and the second drive module 4 and resets them. After the reset is completed, the first drive module 2 and the second drive module 4 are closed. Then the worker moves the next batch of blocks to the cutting area of ​​this device and repeats the above process to complete the separation and cutting operation of the next batch of blocks.

[0041] As the cutting rope 80 moves downward and compresses the block, the block generates resistance against the cutting rope 80, causing it to stop moving. The cutting rope 80 then drives the guide wheel 8 to move relative to the first U-shaped frame 6. The guide wheel 8, through the first rotating shaft 602, drives the first T-shaped block 21 to move relative to the first U-shaped frame 6. The second elastic element 22 gradually stretches until the resistance experienced by the cutting rope 80 is equal to the tension of the second elastic element 22 on the first T-shaped block 21. At this point, the first T-shaped block 21 and the first U-shaped frame 6 stop moving relative to each other. The cutting rope 80 then maintains this state and continues to move downward. When the cutting rope 80 cuts into the insulation layer of the block, the resistance encountered by the cutting rope 80 decreases, which allows the second elastic element 22 to pull the first T-block 21 downward. The first T-block 21 drives the guide wheel 8 downward through the first rotating shaft 602. The guide wheel 8 drives the cutting rope 80 downward. The second elastic element 22 gradually contracts until the compressive force on the cutting rope 80 is consistent with the tension of the second elastic element 22 on the first T-block 21. At this time, the first T-block 21 and the first U-shaped frame 6 stop moving relative to each other. The cutting rope 80 remains in this state and continues to move downward.

[0042] During the relative movement between the guide wheel 8 and the first U-shaped frame 6, the first rotating shaft 602 drives the first mounting box 7 and the guide wheel 8 to move upward, and the first protrusion 601 slides along the first transition groove 10 towards the center of the guide wheel 8 (hereinafter referred to as...). Figure 6 Taking the right guide wheel 8 as an example, the guide wheel 8 rotates counterclockwise, and the first elastic element 9 begins to release. The left guide wheel 8 rotates clockwise in the opposite direction to the right guide wheel 8. The two guide wheels 8 rotate synchronously and tighten the cutting rope 80, increasing the tension of the cutting rope 80. When the pulling force of the second elastic element 22 on the first T-block 21 is the same as the reaction force on the cutting rope 80, the first T-block 21 and the first U-shaped frame 6 stop moving relative to each other, and the increase in the tension of the cutting rope 80 stops. When the cutting rope 80 cuts to the block insulation layer, the first rotating shaft 602 drives the first mounting box 7 and the guide wheel 8 to move downward. The first protrusion 601 slides along the first transition groove 10 in a direction away from the center of the guide wheel 8 (hereinafter referred to as...). Figure 6Taking the right guide wheel 8 as an example, the guide wheel 8 rotates clockwise, and the first elastic element 9 begins to store force. The left guide wheel 8 rotates counterclockwise in the opposite direction to the right guide wheel 8. The two guide wheels 8 rotate synchronously and loosen the cutting rope 80, reducing the tension of the cutting rope 80. When the pulling force of the second elastic element 22 on the first T-block 21 is the same as the reaction force on the cutting rope 80, the first T-block 21 and the first U-shaped frame 6 stop moving relative to each other, and the reduction of the tension of the cutting rope 80 stops, thus completing the entire adjustment action. During the block cutting process, the tension of the cutting rope 80 is changed according to the change in the resistance of the insulation layer and the concrete layer to the cutting rope 80, so that the tension of the cutting rope 80 can be automatically adjusted according to the magnitude of the reaction force on the cutting rope 80, improving the cutting quality of the blocks, increasing the pass rate, and thus enhancing the cutting effect of the cutting rope 80 on the blocks.

[0043] During the process of cutting blocks with cutting rope 80 (hereinafter referred to as...) Figure 6 Taking the right guide wheel 8 as an example, when the cutting rope 80 breaks, the block is no longer squeezed by the cutting rope 80, causing the second elastic element 22 to pull the first T-block 21 to reset. At this time, the first protrusion 601 will slide along the first transition groove 10 away from the center of the guide wheel 8. At this time, the cutting rope 80 breaks, the right-angle frame on the first U-shaped frame 6 loses the upward squeezing force on the cutting rope 80, and the cutting rope 80 loses the upward pulling force on the second elastic element 22. The second elastic element 22 pulls the first T-block 21 downward. The first T-block 21 drives the first protrusion 601 to overcome the limitation of the one-way plate 42 on the first protrusion 601. After overcoming the limitation of the one-way plate 42 on the first protrusion 601, the first protrusion 601 enters the circular groove 41. The one-way plate 42 resets under the action of the first torsion spring. At this time, the guide wheel 8 can slide relative to the first protrusion 601 through the circular groove 41, so that the first The elastic element 9 drives the guide wheel 8 to rotate counterclockwise, which pulls the cutting rope 80 out of the block. The left guide wheel 8 moves in the opposite direction to the right guide wheel 8, causing it to rotate clockwise and pull the cutting rope 80 out of the block. The two guide wheels 8 simultaneously pull the cutting rope 80 out of the block from the broken end of the cutting rope 80, keeping the broken cutting rope 80 away from the block. The two guide wheels 8 rotate to rewind their respective cutting ropes 80 and continue to rotate until the first elastic element 9 loses torque and the guide wheels 8 stop rotating. This reduces the damage to the block caused by the broken cutting rope 80 during subsequent cutting, reduces the impact on the flatness and dimensional accuracy of the block cut surface, and reduces the defect rate. After cutting, the worker operates the drive mechanism to reset the inner frame 5, shuts off the drive mechanism, and replaces the broken cutting rope 80.

[0044] Example 2: Based on Example 1, as follows Figure 6 and Figures 11-14As shown, it also includes: a compensation component, the same number as the cutting rope 80, set on the inner frame 5, used to cut the material in place of the cutting rope 80 when the cutting rope 80 is broken. The compensation component includes: two sliding rods 51, which are slidably connected to both sides of the inner frame 5 respectively. The sliding rods 51 are fixed to a second U-shaped frame 52. A second protrusion 521 is fixed to the second U-shaped frame 52. A second rotating shaft 522 and a second mounting box 53 are slidably connected to the second U-shaped frame 52. A compensation wheel 54 is rotatably connected to the second rotating shaft 522. A third elastic element 55 is fixed between the second mounting box 53 and the compensation wheel 54; a compensation rope 56, fixed between the two compensation wheels 54; two second detection components, respectively set on adjacent second U-shaped frames 52, used to detect the resistance encountered when the compensation wheel 54 moves; and two lifting components, respectively set on adjacent sliding rods 51, used to adjust the height of the sliding rods 51.

[0045] The above-mentioned method for compensating the cutting force of the cutting rope 80 aims to ensure that after the cutting rope 80 breaks, the compensating rope 56 replaces the cutting rope 80 and continues the cutting work, so that the cutting device can still stably perform its cutting function during operation. The compensating rope 56 is made of diamond wire, which can maintain good cutting performance when cutting concrete composite blocks, making the cut surface smoother. The third elastic element 55 is a coil spring, and it is initially in a charged state. The compensating wheel 54 is wrapped with rubber to increase the friction between the compensating wheel 54 and the compensating rope 56 and prevent relative sliding between the compensating wheel 54 and the compensating rope 56. In the initial state, the compensating rope 56 is in a taut state, but its tension is less than that of the cutting rope 80. The compensating rope 56 separates the parts that are stuck together after cutting and can level the surface of the block.

[0046] like Figure 6 , Figure 11 and Figure 12 As shown, the second detection component includes: two second T-shaped blocks 61, which are slidably connected to both sides of the second U-shaped frame 52. Both second T-shaped blocks 61 are rotatably connected to the second rotating shaft 522. A fourth elastic member 622 is fixedly connected between the second T-shaped blocks 61 and the second U-shaped frame 52.

[0047] The above proposes a method for detecting the moving resistance of the compensation wheel 54. By detecting the degree of deformation of the fourth elastic element 62, the magnitude of the resistance experienced by the compensation wheel 54 can be reflected, thereby adjusting the tension of the compensation wheel 54 on the compensation rope 56. The fourth elastic element 62 is a tension spring, and the fourth elastic element 62 can be replaced according to the density changes of different concrete.

[0048] like Figure 6 , Figure 12 and Figure 13 As shown, a second transition groove 71 is provided on the side of the compensation wheel 54 away from the second mounting box 53, and the second protrusion 521 slides within the second transition groove 71.

[0049] The above describes a method of adjusting the compensating wheel 54 based on the moving resistance it experiences, thereby ensuring that the compensating rope 56 maintains a suitable position and tension. The distance between the second transition groove 71 and the center of the compensating wheel 54 gradually decreases from top to bottom (e.g., ...). Figure 10 As shown, this is used to gradually slow down the increasing trend of the tension of the compensating wheel 54, make the stress distribution inside the compensating rope 56 relatively uniform, and extend the service life of the compensating rope 56.

[0050] like Figure 5 , Figure 6 , Figure 11 and Figure 12 As shown, the lifting assembly includes: a rack 91, fixedly connected to the sliding rod 51; a pressing plate 92, fixedly connected to the sliding rod 51, with a fifth elastic element 93 fixedly connected between the pressing plate 92 and the inner frame 5; a transmission assembly, disposed on the guide wheel 8, for driving the rack 91 to move; and a locking assembly, disposed on the inner frame 5, for locking the sliding rod 51.

[0051] The above describes a method for adjusting the height of the second U-shaped frame 52, which allows the compensating rope 56 to move to the position where the cutting rope 80 is disconnected and to replace the cutting rope 80 in cutting the blocks; the length of the toothed portion of the rack 91 is the same as the distance between the cutting rope 80 and the compensating rope 56, so that the compensating rope 56 can accurately reach the position where the cutting rope 80 is disconnected; the fifth elastic element 93 is a spring, which is used to drive the rack 91 to reset.

[0052] like Figures 5-8 As shown, the transmission assembly includes: a transmission gear 94 rotatably connected to the guide wheel 8, and the transmission gear 94 is connected to the rack 91; a number of limiting blocks 95, all slidably connected to the guide wheel 8, and a sixth elastic element 96 fixed between the guide wheel 8 and the limiting blocks 95, the limiting blocks 95 limiting the transmission gear 94; both the transmission gear 94 and the guide wheel 8 are provided with circumferentially distributed blind holes, the cross section of the limiting block 95 is trapezoidal, the number of blind holes on the limiting block 95 is the same as the number of blind holes on the guide wheel 8, and the limiting block 95 is located in the adjacent blind holes on the guide wheel 8.

[0053] The above describes a method for transmitting power to the second U-shaped frame 52, the purpose of which is to transmit power to the transmission gear 94 after the cutting rope 80 is disconnected. Both the transmission gear 94 and the guide wheel 8 are provided with circumferentially distributed blind holes. The number of blind holes on the transmission gear 94 is the same as the number of blind holes on the guide wheel 8. The limiting block 95 slides within the blind holes of the guide wheel 8. The sixth elastic element 96 is a tension spring. When the guide wheel 8 rotates normally, the limiting block 95 cannot overcome the tension of the sixth elastic element 96, and the limiting block 95 remains stationary. When the cutting rope 80 is disconnected, the guide wheel 8 rotates rapidly, and the centrifugal force overcomes the tension of the sixth elastic element 96, causing the limiting block 95 to enter the transmission gear 94 and drive the transmission gear 94 to rotate. The shape and position of the limiting block 95 and the sixth elastic element 96 can be modified according to the actual situation.

[0054] like Figure 5 , Figure 6 ,and Figure 14 As shown, the locking assembly includes: a limiting shell 101, which is fixedly connected to the inner frame 5; a locking block 102 is slidably connected to the limiting shell 101; the locking block 102 is used to limit the pressing plate 92; and a seventh elastic member 103 is fixedly connected between the locking block 102 and the limiting shell 101.

[0055] The above proposes a one-way locking method for the sliding rod 51, which can keep the compensating rope 56 stable after it reaches the position where the cutting rope 80 is disconnected; the front and rear sides of the extrusion plate 92 have protrusions, and the lower side of the protrusions on the extrusion plate 92 is provided with an inclined surface. The protrusions on the front and rear sides of the extrusion plate 92 can enter the limiting shell 101 and be limited by the locking block 102.

[0056] When a special circumstance occurs (such as excessive wear of the metal cutting wire) causing the cutting rope 80 to break, the first elastic element 9 drives the guide wheel 8 to rotate rapidly. The guide wheel 8 drives the limiting block 95 to rotate via the sixth elastic element 96. When the centrifugal force on the limiting block 95 is greater than the tension of the sixth elastic element 96, the limiting block 95 enters the blind hole of the transmission gear 94 (the sixth elastic element 96 is stretched). The limiting block 95 limits the transmission gear 94 and drives the transmission gear 94 to rotate. The transmission gear 94 drives the rack 91 to move downward. The rack 91 drives the extrusion plate 92 and the second U-shaped frame 52 to move downward via the sliding rod 51. The fifth elastic element 93 is gradually compressed. The second U-shaped frame 52 drives the internal parts to move downward together via the second protrusion 521 and the second mounting box 53. When the compensation rope 56 reaches the cutting rope 80... At the cutting position when disconnected, the transmission gear 94 and rack 91 lose meshing, and the transmission gear 94 contacts the upper side of the rack 91. The rack 91 limits the transmission gear 94, and the transmission gear 94 stops rotating. The transmission gear 94 presses against the limiting block 95, causing the limiting block 95 to overcome the centrifugal force and retract (the sixth elastic element 96 is compressed). The limiting block 95 loses its limit on the transmission gear 94, completing the descent action. At this time, the guide wheel 8 continues to rotate and winds up the cutting rope 80. After the guide wheel 8 finishes winding up the cutting rope 80, it continues to rotate until the first elastic element 9 loses torque, and the guide wheel 8 stops rotating. At this time, the compensation rope 56 replaces the cutting rope 80 to continue the cutting action, so as to avoid the deviation of the cutting size when recutting after the cutting rope 80 is disconnected, and reduce the waste of blocks and improve the utilization rate of blocks.

[0057] As the sliding rod 51 moves downward, the pressing plate 92 moves downward, contacting and pressing the locking block 102. The locking block 102 presses the seventh elastic element 103, causing the locking block 102 to move away from the pressing plate 92. When the locking block 102 loses contact with the pressing plate 92, the transmission gear 94 and rack 91 disengage, and the locking block 102 resets under the action of the seventh elastic element 103. The reset locking block 102 limits the pressing plate 92, thus locking the pressing plate 92 and preventing the compensation rope from moving downward. After reaching the cutting position where the cutting rope 80 breaks, the compensation rope 56 can be fixed at this position. At this time, the compensation rope 56 is located at the cutting position where the cutting rope 80 breaks and performs the cutting operation in place of the cutting rope 80. After the cutting is completed, the worker opens the drive mechanism and resets the inner frame 5. After the reset, the worker closes the drive mechanism. While the worker replaces the cutting rope 80, he pulls the locking block 102 to move outward, thereby releasing the locking block 102 from limiting the pressing plate 92, so that the pressing plate 92 drives the parts on it to reset upward through the fifth elastic element 93.

[0058] When the compensating rope 56 reaches the cutting position where the cutting rope 80 disconnects, the compensating rope 56 continues the cutting action in place of the cutting rope 80. As the compensating rope 56 contacts and compresses the block, the block generates resistance against the compensating rope 56, causing it to stop moving. The compensating rope 56 drives the compensating wheel 54 to move relative to the second U-shaped frame 52. The compensating wheel 54, through the second rotating shaft 522, drives the second T-shaped block 61 to move relative to the second U-shaped frame 52. The fourth elastic element 62 gradually stretches until the compensating force between the compensating rope 56 and the block and the tension of the fourth elastic element 62 are equal. At this point, the compensating rope 56... 6. Maintain this state and move downward to cut the block. When the compensating rope 56 cuts to the block insulation layer, the resistance of the compensating rope 56 decreases, which allows the fourth elastic element 62 to pull the second T-block 61 downward. The second T-block 61 drives the compensating wheel 54 downward through the second rotating shaft 522. The compensating wheel 54 drives the compensating rope 56 downward until the compensating rope 56 is subjected to the same compressive force as the fourth elastic element 62 on the second T-block 61. At this time, the second T-block 61 and the second U-shaped frame 52 stop moving relative to each other. The compensating rope 56 maintains this state and moves downward.

[0059] During the relative movement between the compensation wheel 54 and the second U-shaped frame 52, the second rotating shaft 522 drives the second mounting box 53 and the compensation wheel 54 to move upward. During the upward movement of the compensation wheel 54, the second protrusion 521 slides along the second transition groove 71 towards the center of the compensation wheel 54 (hereinafter referred to as...). Figure 6 Taking the right compensation wheel 54 as an example, the compensation wheel 54 rotates counterclockwise, and the third elastic element 55 begins to release. The left compensation wheel 54 rotates clockwise in the opposite direction to the right compensation wheel 54. The two compensation wheels 54 rotate synchronously and tighten the compensation rope 56, increasing the tension of the compensation rope 56. When the pulling force of the fourth elastic element 62 on the second T-block 61 is the same as the reaction force on the compensation rope 56, the increase in the tension of the compensation rope 56 stops. When the compensation rope 56 cuts to the block insulation layer, the second rotating shaft 522 drives the second mounting box 53 and the compensation wheel 54 to move downwards. The second protrusion 521 slides along the second transition groove 71 in a direction away from the center of the compensation wheel 54 (hereinafter referred to as...). Figure 6Taking the right-side compensation wheel 54 as an example, the compensation wheel 54 rotates clockwise, and the third elastic element 55 begins to store force. The left-side compensation wheel 54 rotates counterclockwise in the opposite direction to the right-side compensation wheel 54. The two compensation wheels 54 rotate synchronously and loosen the compensation rope 56, reducing the tension of the compensation rope 56. This continues until the tension of the second T-block 61 by the fourth elastic element 62 is equal to the reaction force on the compensation rope 56. At this point, the second T-block 61 and the second U-shaped frame 52 stop moving relative to each other, thus stopping the reduction of the tension of the compensation rope 56 and completing the entire adjustment action. During the block cutting process, the tension of the compensation rope 56 is changed according to the change in the resistance of the insulation layer and the concrete layer. This allows the tension of the compensation rope 56 to be automatically adjusted according to the magnitude of the reaction force on the compensation rope 56, improving the flatness of the block cut by the compensation rope 56, improving the cutting quality of the block, and thus enhancing the cutting effect of the compensation rope 56 on the block.
