Description

Technical Field

[0001] The invention relates to the technical field of concrete block cutting, in particular to a cutting device for producing concrete composite blocks. Background Art

[0002] Concrete composite block cutting refers to the process of cutting concrete materials into blocks of specific size and shape. This kind of cutting usually requires the use of professional concrete cutting equipment, such as wire cutting machines, concrete cutting machines, electric saws or laser cutting machines.

[0003] In the current cutting method, the wire cutting machine mainly cuts the concrete by the extrusion force of the metal cutting wire. Usually, the operator adjusts the tension of the metal cutting wire to change the extrusion force on the concrete, so as to adapt to concrete blocks of different hardness. However, for concrete composite blocks, the concrete composite block itself is composed of a stacked concrete layer and an insulation layer. The hardness of each layer of the concrete composite block is different. The existing wire cutting machine only adjusts the tension for the extrusion force required by the harder concrete layer during cutting, so as to cut the concrete composite block. When cutting the insulation layer with lower hardness, the extrusion force of the metal cutting wire is too large relative to the insulation layer. The insulation layer will be excessively deformed when being cut, and collapse and adhesion will occur, affecting the overall cutting quality of the concrete composite block.

[0017] During the normal cutting process of the present invention, the compensating rope separates the area where the concrete is adhered again after being cut by the cutting rope, thereby improving the flatness of the cut concrete surface and further improving the cutting quality of the concrete block. After the cutting rope is disconnected, the compensating rope is moved to the position where the cutting rope is disconnected under the drive of the rack, and continues cutting in place of the cutting rope. This not only avoids the cutting trajectory deviation caused by replacement or repositioning of the cutting rope, but also the automatic compensation of the compensating rope reduces the loss caused by abnormal working conditions of the equipment and maintains the stability of the equipment operation.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: A cutting device for producing concrete composite blocks, such as Figure 1-Figure 10 As shown, it includes: a support frame 1, the support frame 1 is slidably connected to an outer frame 3, the outer frame 3 is slidably connected to an inner frame 5, and the support frame 1 is equipped with a driving mechanism for driving the outer frame 3 and the inner frame 5 to move; a cutting component, which has several parts and is all arranged on the inner frame 5 for cutting the material, and the cutting component includes: a first U-shaped frame 6, which has two parts and is respectively fixed to the two sides of the inner frame 5, and the first U-shaped frame 6 is slidably connected to the first installation box 7; a guide wheel 8, which has two parts and is respectively rotatably connected to the adjacent first installation boxes 7, a cutting rope 80 is fixed between the two guide wheels 8, a first transition groove 10 is arranged on one side of the guide wheel 8, the first U-shaped frame 6 is fixed with a first boss 601 sliding in the first transition groove 10, and a first elastic member 9 is fixed between the guide wheel 8 and the first installation box 7; a first detection component, which has two parts and is respectively arranged on adjacent first U-shaped frames 6 for detecting the resistance encountered by the guide wheel 8 when it moves.

[0022] In the above scheme, a method of changing the tension of the cutting rope 80 and cutting the concrete composite building block is proposed, aiming to improve the cutting quality and cutting efficiency of the building block; the material proposed in this article refers to the concrete composite building block, and the driving mechanism is composed of a first driving module 2 and a second driving module 4. The first driving module 2 is used to drive the outer frame 3 and the parts thereon to move up and down, and the second driving module 4 is used to drive the inner frame 5 and the parts thereon to move left and right, thereby reducing the cutting resistance and making the cutting force more evenly distributed on the cutting surface of the building block, thereby improving the quality of the cut building block; A right angle frame is provided on a U-shaped frame 6, which ensures that the cutting rope 80 remains horizontal and exerts an upward squeezing effect on the cutting rope 80; the cutting rope 80 is a corundum wire, which can maintain good cutting performance when cutting concrete composite blocks, making the cutting surface smoother; the first elastic member 9 is a coil spring, and it is initially in a power storage state; the guide wheel 8 is wrapped with rubber to increase the friction between the guide wheel 8 and the cutting rope 80, and prevent the guide wheel 8 and the cutting rope 80 from sliding relative to each other; the distance between the first transition groove 10 and the center of the guide wheel 8 gradually decreases from top to bottom (such as Fig.10 As shown), it is used to gradually slow down the increasing trend of the tensioning force of the guide wheel 8, so that the stress distribution inside the cutting rope 80 is relatively uniform, thereby extending the service life of the cutting rope 80.

[0023] like Figure 6 , Figure 8 and Fig. 9 As shown, the first detection component includes: two first T-blocks 21, which are slidably connected to both sides of the first U-shaped frame 6 respectively, a second elastic member 22 is fixedly connected between the first T-block 21 and the first U-shaped frame 6, the guide wheel 8 is fixedly connected to the first rotating shaft 602, and the first T-block 21 is rotatably connected to the first rotating shaft 602.

[0024] The above-mentioned method proposes a method for detecting the moving resistance of the guide wheel 8, and the deformation degree of the second elastic member 22 reflects the size of the resistance encountered by the guide wheel 8, so that the guide wheel 8 can adjust the tensioning force of the cutting rope 80; the second elastic member 22 is a tension spring, and the initial state of the second elastic member 22 is a stretched state under the squeezing effect of the right-angle frame on the first U-shaped frame 6 on the cutting rope 80, and the second elastic member 22 can be replaced according to the density changes of different concretes.

[0025] like Figure 6 , Fig. 9 and Fig.10 As shown, a circular groove 41 is provided on the side of the guide wheel 8 away from the first mounting box 7, and 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, and the one-way plate 42 is used to limit the first boss 601.

[0026] The above-mentioned method proposes a method for rotating the guide wheel 8 when the cutting rope 80 is disconnected, so as to rotate the guide wheel 8 to drive the cutting rope 80 to be pulled out of the concrete composite block; there is a first torsion spring in the one-way plate 42, and the first torsion spring can control the one-way plate 42 to reset. The one-way plate 42 can make the first boss 601 enter the circular groove 41 from the first transition groove 10, and cannot make the first boss 601 enter the first transition groove 10 through the circular groove 41.

[0027] When using the device to cut concrete composite blocks (hereinafter referred to as blocks), the worker first moves the blocks to the cutting area of ​​the device, and then the worker starts the first drive module 2 and the second drive module 4, the first drive module 2 drives the outer frame 3 and the parts thereon to descend, 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 thereon and the parts therein to move, in the process of the outer frame 3 and the parts thereon descending, the outer frame 3 drives the inner frame 5 to move downward, the inner frame 5 drives all the first U-shaped frames 6 thereon to move downward, the first U-shaped frame 6 drives the first T-block 21 to move downward through the second elastic member 22, the first T-block 21 drives the first installation box 7 and the guide wheel 8 to move downward through the first rotating shaft 602, and the first The installation box 7 drives the first elastic member 9 to move downward, and the guide wheel 8 drives the cutting rope 80 to move downward. The cutting rope 80 moves downward and squeezes the blocks. The blocks are separated into required sizes by squeezing the blocks by the cutting rope 80. When the cutting rope 80 passes through the blocks and moves downward to the limit position, after the cutting is completed, the worker turns off the first driving module 2 and the second driving module 4, and transports the cut blocks to the subsequent processing area (molding). After the blocks are transported out of the cutting area of ​​the device, the worker starts the first driving module 2 and the second driving module 4 and resets them. After the reset is completed, the first driving module 2 and the second driving module 4 are turned off. Then the worker moves the next batch of blocks into the cutting area of ​​the device and repeats the above process to complete the separation and cutting operation of the next batch of blocks.

[0028] When the cutting rope 80 moves downward and squeezes the building blocks, the building blocks generate resistance to the cutting rope 80, causing the cutting rope 80 to stop moving. The cutting rope 80 drives the guide wheel 8 and the first U-shaped frame 6 to move relative to each other. The guide wheel 8 drives the first T-shaped block 21 and the first U-shaped frame 6 to move relative to each other through the first rotating shaft 602. The second elastic member 22 is gradually stretched until the resistance of the cutting rope 80 is consistent with the pulling force of the second elastic member 22 on the first T-shaped block 21. The first T-shaped block 21 and the first U-shaped frame 6 stop moving relative to each other. At this time, the cutting rope 80 maintains this state and moves downward. The block is cut. When the cutting rope 80 cuts into the insulating layer of the block, the resistance encountered by the cutting rope 80 becomes smaller, so that the second elastic member 22 can pull the first T-block 21 downward. The first T-block 21 drives the guide wheel 8 to move downward through the first rotating shaft 602. The guide wheel 8 drives the cutting rope 80 to move downward. The second elastic member 22 gradually contracts until the extrusion force on the cutting rope 80 is consistent with the pulling force of the second elastic member 22 on the first T-block 21. The first T-block 21 and the first U-shaped frame 6 stop moving relative to each other. At this time, the cutting rope 80 maintains this state and moves downward.

[0029] 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 protruding column 601 slides along the first transition groove 10 toward the direction close to 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, the first elastic member 9 begins to release, and the left guide wheel 8 moves in the opposite direction to the above-mentioned right guide wheel 8, causing the left guide wheel 8 to rotate clockwise. The two guide wheels 8 rotate synchronously and tighten the cutting rope 80, increasing the tension of the cutting rope 80 until the pulling force of the second elastic member 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 then stop increasing the tension of the cutting rope 80. When the cutting rope 80 cuts the building block insulation layer, the first rotating shaft 602 drives the first installation box 7 and the guide wheel 8 to move downward, and the first protrusion 601 slides along the first transition groove 10 in the direction away from 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 clockwise, the first elastic member 9 starts to accumulate force, and the left guide wheel 8 moves in the opposite direction to the above-mentioned right guide wheel 8, so that the left guide wheel 8 rotates counterclockwise, and the two guide wheels 8 rotate synchronously and relax the cutting rope 80, reducing the tension of the cutting rope 80, until the pulling force of the second elastic member 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 then stop reducing the tension of the cutting rope 80, and complete the entire adjustment action. During the block cutting process, the tension of the cutting rope 80 is changed according to the change of 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 size of the reaction force on the cutting rope 80, thereby improving the cutting quality of the blocks, improving the pass rate, and thus enhancing the cutting effect of the cutting rope 80 on the blocks.

[0030] During the process of cutting the blocks by the cutting rope 80 (hereinafter referred to as Figure 6Taking the right guide wheel 8 in the middle as an example), when the cutting rope 80 is disconnected, the building block no longer squeezes the cutting rope 80, so that the second elastic member 22 pulls the first T-shaped block 21 to reset. At this time, the first protrusion 601 will slide along the first transition groove 10 in the direction away from the center of the guide wheel 8. At this time, the cutting rope 80 is disconnected, and 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 member 22. The second elastic member 22 pulls the first T-shaped block 21 downward, and the first T-shaped block 21 drives the first protrusion 601 to overcome the limit of the one-way plate 42 on the first protrusion 601. After overcoming the limit of the one-way plate 42 on the first protrusion 601, the first protrusion 601 enters the circular groove 41, and the one-way plate 42 is reset 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 member 9 drives the guide wheel 8 to rotate counterclockwise, and the guide wheel 8 rotates counterclockwise to pull the cutting rope 80 out of the block. The left guide wheel 8 moves in the opposite direction to the above-mentioned right guide wheel 8, so that the left guide wheel 8 rotates clockwise and pulls the cutting rope 80 out of the block. The two guide wheels 8 respectively extract the cutting rope 80 in the block from the broken end of the cutting rope 80, so that the broken cutting rope 80 is away from the block. The two guide wheels 8 rotate and rewind their respective cutting ropes 80 and continue to rotate until the first elastic member 9 loses torque and the guide wheel 8 stops rotating, thereby reducing the damage caused to the block by the broken cutting rope 80 in the subsequent cutting process, reducing the impact on the flatness and dimensional accuracy of the cutting surface of the block, and reducing the defective rate. After cutting, the worker controls the driving mechanism to drive the inner frame 5 to reset, the worker turns off the driving mechanism, and replaces the broken cutting rope 80.

[0031] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 11-Figure 14 As shown, it also includes: compensation components, the number of which is the same as the number of cutting ropes 80, which are arranged on the inner frame 5 and are used to replace the cutting rope 80 to cut the material when the cutting rope 80 is disconnected. The compensation components include: sliding rods 51, the number of which is two, which are slidably connected to both sides of the inner frame 5, the sliding rod 51 is fixedly connected to a second U-shaped frame 52, the second U-shaped frame 52 is fixedly connected to a second protruding column 521, the second U-shaped frame 52 is slidably connected to a second rotating shaft 522 and a second mounting box 53, the second rotating shaft 522 is rotatably connected to a compensation wheel 54, and a third elastic member 55 is fixedly connected between the second mounting box 53 and the compensation wheel 54; compensation ropes 56, which are fixedly connected between the two compensation wheels 54; second detection components, the number of which is two, which are respectively arranged on adjacent second U-shaped frames 52, and are used to detect the resistance encountered by the compensation wheel 54 when it moves; lifting components, the number of which is two, which are respectively arranged on adjacent sliding rods 51, and are used to adjust the height of the sliding rod 51.

[0032] The above-mentioned method proposes a method for compensating the cutting force of the cutting rope 80, the purpose of which is to ensure that after the cutting rope 80 is disconnected, the cutting rope 80 is replaced by the compensation rope 56 and the cutting work is continued, so that the cutting device can still stably perform the cutting function during the working process; the compensation rope 56 is a corundum wire, and the corundum wire can maintain good cutting performance when cutting concrete composite blocks, making the cutting surface smoother; the third elastic member 55 is a coil spring, and it is initially in a power storage state; the compensation wheel 54 is wrapped with rubber to increase the friction between the compensation wheel 54 and the compensation rope 56 to prevent the compensation wheel 54 and the compensation rope 56 from sliding relative to each other; in the initial state, the compensation rope 56 is in a taut state, but its tension is smaller than the tension 80 of the cutting rope. The compensation rope 56 separates the position that is adhered again after cutting, and can level the surface of the block.

[0033] like Figure 6 , Fig.11 and Fig.12 As shown, the second detection component includes: two second T-blocks 61, which are slidably connected to the two sides of the second U-shaped frame 52 respectively, and the two second T-blocks 61 are both rotatably connected to the second rotating shaft 522, and a fourth elastic member 622 is fixedly connected between the second T-block 61 and the second U-shaped frame 52.

[0034] The above-mentioned method proposes a method for detecting the moving resistance of the compensation wheel 54. By detecting the deformation degree of the fourth elastic member 62, the resistance encountered by the compensation wheel 54 is reflected, and then the compensation wheel 54 adjusts the tensioning force of the compensation rope 56; the fourth elastic member 62 is a tension spring, and the fourth elastic member 62 can be replaced according to the density changes of different concrete.

[0035] like Figure 6 , Fig.12 and Fig.13 As shown, a second transition groove 71 is provided on a side of the compensation wheel 54 away from the second installation box 53 , and the second protrusion 521 is located in the second transition groove 71 and slides.

[0036] The above-mentioned method proposes a method of adjusting the compensation wheel 54 according to the moving resistance of the compensation wheel 54 to rotate, so as to keep the compensation rope 56 in a suitable position and tension state at all times; the distance between the second transition groove 71 and the center of the compensation wheel 54 gradually decreases from top to bottom (such as Fig.10 As shown), it is used to gradually slow down the trend of increasing the tension of the compensation wheel 54, so that the stress distribution inside the compensation rope 56 is relatively uniform, thereby extending the service life of the compensation rope 56; like Figure 5 , Figure 6 , Fig.11 and Fig.12As shown, the lifting assembly includes: a rack 91, fixed to the sliding rod 51; an extrusion plate 92, fixed to the sliding rod 51, and a fifth elastic member 93 fixed between the extrusion plate 92 and the inner frame 5; a transmission assembly, arranged on the guide wheel 8, for driving the rack 91 to move; a locking assembly, arranged on the inner frame 5, for locking the sliding rod 51.

[0037] The above-mentioned method of adjusting the height of the second U-shaped frame 52 is used to enable the compensation rope 56 to move to the position where the cutting rope 80 is disconnected, and replace the cutting rope 80 to cut the blocks; the length of the tooth part on the rack 91 is the same as the distance between the cutting rope 80 and the compensation rope 56, so that the compensation rope 56 can accurately reach the position where the cutting rope 80 is disconnected; the fifth elastic member 93 is a spring, which is used to drive the rack 91 to reset.

[0038] like Figure 5-Figure 8 As shown, the transmission assembly includes: a transmission gear 94, which is rotatably connected to the guide wheel 8, and the transmission gear 94 is transmission-connected to the rack 91; there are a plurality of limit blocks 95, all of which are slidably connected to the guide wheel 8, and a sixth elastic member 96 is fixedly connected between the guide wheel 8 and the limit block 95, and the limit block 95 limits the transmission gear 94; the transmission gear 94 and the guide wheel 8 are both provided with circumferentially distributed blind holes, the cross-section of the limit block 95 is trapezoidal, the number of blind holes on the limit block 95 is the same as that on the guide wheel 8, and the limit block 95 is located in the adjacent blind holes on the guide wheel 8.

[0039] The above-mentioned method of transmitting the second U-shaped frame 52 is aimed at transmitting the transmission gear 94 after the cutting rope 80 is disconnected; the transmission gear 94 and the guide wheel 8 are both 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, and the limit block 95 slides in the blind hole of the guide wheel 8; the sixth elastic member 96 is a tension spring, when the guide wheel 8 rotates normally, the limit block 95 cannot overcome the tension of the sixth elastic member 96, and the limit block 95 remains stationary. When the cutting rope 80 is disconnected, the guide wheel 8 rotates rapidly, the centrifugal force overcomes the tension of the sixth elastic member 96 and causes the limit block 95 to enter the transmission gear 94, and drives the transmission gear 94 to rotate. The shape and position of the limit block 95 and the sixth elastic member 96 can be modified according to actual conditions.

[0040] like Figure 5 , Figure 6 ,and Fig.14 As shown, the locking assembly includes: a limiting shell 101 fixed to the inner frame 5, the limiting shell 101 is slidably connected to a clamping block 102, the clamping block 102 is used to limit the extrusion plate 92, and a seventh elastic member 103 is fixed between the clamping block 102 and the limiting shell 101.

[0041] The above-mentioned method proposes a one-way locking method for the sliding rod 51, which is used to ensure that the compensation rope 56 can remain stable after reaching the position where the cutting rope 80 is disconnected; the front and rear sides of the extrusion plate 92 both have protrusions, and the lower side of the protrusion on the extrusion plate 92 is provided with a slope. The protrusions on the front and rear sides of the extrusion plate 92 can enter the limiting shell 101 and be limited by the block 102.

[0042] When a special situation occurs (such as excessive wear of the metal cutting wire) causing the cutting rope 80 to break, the first elastic member 9 drives the guide wheel 8 to rotate rapidly, and the guide wheel 8 drives the limit block 95 to rotate through the sixth elastic member 96. When the centrifugal force on the limit block 95 is greater than the pulling force of the sixth elastic member 96, the limit block 95 enters the blind hole of the transmission gear 94 (the sixth elastic member 96 is stretched), and the limit 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, and the rack 91 drives the extrusion plate 92 and the second U-shaped frame 52 to move downward through the sliding rod 51. The fifth elastic member 93 is gradually compressed, and the second U-shaped frame 52 drives its internal parts to move downward together through the second protruding column 521 and the second mounting box 53. When the compensation rope 56 reaches the cutting rope 80 When in the cutting position during disconnection, the transmission gear 94 and the rack 91 lose engagement, the transmission gear 94 contacts the upper side of the rack 91, the rack 91 limits the transmission gear 94, the transmission gear 94 stops rotating, the transmission gear 94 squeezes the limit block 95, so that the limit block 95 overcomes the centrifugal force and retracts (the sixth elastic member 96 is compressed), the limit block 95 loses the limit on the transmission gear 94, and the descending action is completed. At this time, the guide wheel 8 continues to rotate and rewinds the cutting rope 80. After the guide wheel 8 rewinds the cutting rope 80, it continues to rotate until the first elastic member 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 to avoid deviation in the cutting size when re-cutting after the cutting rope 80 is disconnected, and to reduce the waste of building blocks and improve the utilization rate of building blocks.

[0043] When the sliding rod 51 moves downward, the extrusion plate 92 moves downward, the extrusion plate 92 contacts and squeezes the card block 102, and the card block 102 squeezes the seventh elastic member 103, so that the card block 102 moves away from the extrusion plate 92. When the card block 102 loses contact with the extrusion plate 92, the transmission gear 94 and the rack 91 lose meshing, and the card block 102 is reset under the action of the seventh elastic member 103. The reset card block 102 limits the extrusion plate 92, plays a locking role on the extrusion plate 92, so that the compensation rope After 56 reaches the cutting position when the cutting rope 80 is disconnected, it can be fixed at this position. At this time, the compensation rope 56 is located at the cutting position when the cutting rope 80 is disconnected, and replaces the cutting rope 80 to perform the cutting operation. After completing the cutting, the worker opens the driving mechanism and resets the inner frame 5. After resetting, 1 closes the driving mechanism. While replacing the cutting rope 80, the worker pulls the block 102 to move outward, thereby releasing the limit of the block 102 on the extrusion plate 92, so that the extrusion plate 92 drives the parts thereon to reset upward through the fifth elastic member 93.

[0044] When the compensation rope 56 reaches the cutting position where the cutting rope 80 is disconnected, the compensation rope 56 replaces the cutting rope 80 to continue the cutting action. As the compensation rope 56 contacts and squeezes the building block, the building block generates resistance to the compensation rope 56, causing the compensation rope 56 to stop moving. The compensation rope 56 drives the compensation wheel 54 and the second U-shaped frame 52 to move relative to each other. The compensation wheel 54 drives the second T-shaped block 61 and the second U-shaped frame 52 to move relative to each other through the second rotating shaft 522. The fourth elastic member 62 is gradually stretched until the squeezing force of the compensation rope 56 and the building block is consistent with the pulling force of the fourth elastic member 62. At this time, the compensation rope 56 is 6 maintains this state and moves downward to cut the building block. When the compensation rope 56 cuts the insulation layer of the building block, the resistance encountered by the compensation rope 56 becomes smaller, so that the fourth elastic member 62 can pull the second T-block 61 downward. The second T-block 61 drives the compensation wheel 54 to move downward through the second rotating shaft 522. The compensation wheel 54 drives the compensation rope 56 downward until the extrusion force on the compensation rope 56 is consistent with the pulling force of the fourth elastic member 62 on the second T-block 61. The second T-block 61 and the second U-shaped frame 52 stop moving relative to each other. At this time, the compensation rope 56 maintains this state and moves downward.

[0045] 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 toward the direction close to the center of the compensation wheel 54 (hereinafter referred to as Figure 6Taking the right compensation wheel 54 as an example), the compensation wheel 54 rotates counterclockwise, the third elastic member 55 begins to release, and the left compensation wheel 54 moves in the opposite direction to the above-mentioned right compensation wheel 54, so that the left compensation wheel 54 rotates clockwise, and the two compensation wheels 54 rotate synchronously and tighten the compensation rope 56, thereby increasing the tension of the compensation rope 56. When the pulling force of the fourth elastic member 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 is stopped. When the compensation rope 56 cuts into the building block insulation layer, the second rotating shaft 522 drives the second installation box 53 and the compensation wheel 54 to move downward, and 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 6 Taking the right compensation wheel 54 as an example), the compensation wheel 54 rotates clockwise, the third elastic member 55 starts to accumulate force, and the left compensation wheel 54 moves in the opposite direction to the above-mentioned right compensation wheel 54, causing the left compensation wheel 54 to rotate counterclockwise, and the two compensation wheels 54 rotate synchronously and relax the compensation rope 56, reducing the tension of the compensation rope 56, until the pulling force of the fourth elastic member 62 on the second T-block 61 is the same as the reaction force on the compensation rope 56, the second T-block 61 and the second U-shaped frame 52 stop moving relative to each other, and then stop reducing the tension of the compensation rope 56, and complete the entire adjustment action. During the block cutting process, the tension of the compensation rope 56 is changed according to the change in the hardness of the insulation layer and the concrete layer to the change in the resistance of the compensation rope 56, so that the tension of the compensation rope 56 can be automatically adjusted according to the size of the reaction force on the compensation rope 56, thereby improving the cutting flatness of the blocks by the compensation rope 56, improving the cutting quality of the blocks, and thereby enhancing the cutting effect of the compensation rope 56 on the blocks.
