Description

Technical Field

[0001] The present invention relates to the technical field of civil and construction engineering, and specifically, to a laser positioning wire saw for building concrete with vibration suppression. Background Art

[0002] Concrete structure components such as precast reinforced concrete frames refer to building load-bearing components composed of prefabricated concrete and steel bars through industrial production. During the building process, the wire saw technology is mainly applied in the later correction and precise forming stages. For non-standard precast components such as curved beams and curved floor slabs, the wire saw can correct complex geometric shapes that are difficult to form by traditional molds through three-dimensional cutting.

[0003] Currently, when the existing wire saw is in use, the following defects exist:

[0004] First, the existing wire saw generally drives the guide wheel connected thereto to rotate through a driving source. The rotation of the guide wheel drives the chain to rotate in a friction drive manner. The rotation of the chain cuts and corrects concrete structure components such as precast reinforced concrete frames. However, the connection between the guide wheel and the chain is usually directly exposed to the working environment. When the staff observes the working conditions of the guide wheel and the chain, their clothes are easily entangled by the guide wheel and the chain, leading to safety accidents.

[0005] Second, when the chain cuts concrete structure components such as precast reinforced concrete frames, cold water is generally used to cool the cutting part of the chain and the component to reduce frictional heat and extend the life of the chain. However, since the chain is constantly rotating, the surface of the chain leaving the cutting part still has debris such as concrete. When the chain rotates onto the guide wheel, these debris attached to the chain will also contact the guide wheel. The debris exerts destructive forces on the chain and the guide wheel, and continuously damages the surfaces of the guide wheel and the chain, reducing the service life of the guide wheel and the chain. In view of this, we propose a laser positioning wire saw for building concrete with vibration suppression. Summary of the Invention

[0006] The purpose of the present invention is to provide a laser positioning wire saw for building concrete with vibration suppression. It wraps the connection between the guide wheel and the chain through a protection mechanism to generate an axial force, adapt to the cutting direction of the chain at multiple angles, and generate an oblique force to expand and extend itself to adjust the protection range, preventing the connection between the guide wheel and the chain from getting caught in the clothes or hair of the approaching staff; it operates the flushing mechanism to introduce water into the protection mechanism to flush the surface of the chain in advance, and the flushing mechanism cooperates with the suppression mechanism. When the suppression mechanism reduces the vibration amplitude of the chain, due to the reduction of the vibration amplitude, the stability of the chain during rotation is improved. The suppression mechanism simultaneously reduces the water spray range of the flushing mechanism, and the flushing mechanism cooperates with the protection mechanism. The water sprayed by the flushing mechanism temporarily stays in the protection mechanism, so that the chain located below the guide wheel is immersed in the water.

[0007] To achieve the above-mentioned purpose, a vibration-suppressed construction concrete laser positioning wire saw comprises a frame, a driving device is installed on the top of the frame, a guide wheel is fixedly arranged at the output end of the driving device, a chain is transmission-connected to the surface of the guide wheel, a protective mechanism for covering the guide wheel and the chain is arranged on the circumference of the guide wheel, one end of the chain away from the driving device is arranged on the outside of the protective mechanism, the protective mechanism generates an axial force to rotate itself, adapts to the cutting direction of the chain at multiple angles, and generates an oblique force to retract and extend itself to adjust the protection range and form a cavity, the protective mechanism A flushing mechanism for cleaning the chain is arranged on the top of the protective mechanism, and both the protective mechanism and the flushing mechanism are connected to the driving device. The output end of the flushing mechanism is arranged in the cavity, and cooperates with the cavity to receive the water source and immerse the chain in the cavity. Suppression mechanisms for suppressing the vibration generated when the chain is cut are symmetrically arranged on both sides of the protective mechanism. The two suppression mechanisms generate a relative horizontal axial force to suppress the vibration amplitude of the chain and change the flow range and direction of the water source sprayed by the flushing mechanism to cooperate with the flushing mechanism to change the water source flow rate.

[0008] As a further improvement of the present technical solution, the protective mechanism includes a fixed seat, which is fixedly arranged on one side of the driving device on a side close to the frame, and a protective shell is fixedly arranged on a side of the fixed seat away from the frame by fastening bolts, and an end of the protective shell away from the guide wheel is arranged as an opening, and the guide wheel, the output end of the flushing mechanism and the output end of the suppression mechanism are all arranged in the protective shell.

[0009] As a further improvement of the present technical solution, a protective sleeve is slidably provided at the opening of the protective shell, and one end of the protective sleeve extends out of the interior of the protective shell to adjust the protection range; the outer wall size of the protective sleeve is adapted to the inner wall size of the protective shell.

[0010] As a further improvement of the technical solution, the first fixed blocks are symmetrically fixed at one end of the top and bottom of the protective shell, the first cylinders are fixedly arranged on the side of the two first fixed blocks away from the guide wheel, the second fixed blocks are fixedly arranged at the output ends of the two first cylinders, and the bottom ends of the two second fixed blocks are fixedly connected to the top and bottom of the protective cover respectively.

[0011] As a further improvement of the present technical solution, the flushing mechanism includes a nozzle, which is fixedly arranged at the other end of the top of the protective shell, and the output end of the nozzle is located inside the protective shell and is arranged corresponding to the chain.

[0012] As a further improvement of the technical solution, the flushing mechanism further includes a water pump. The bottom of the water pump is fixedly arranged on the top of the driving device. The output end of the water pump is fixedly communicated with a hose. One end of the hose away from the water pump is fixedly communicated with a conduit. One end of the conduit away from the water pump is fixedly communicated with the input end of the nozzle.

[0013] As a further improvement of the technical solution, both of the suppression mechanisms include second cylinders. The end covers of the two second cylinders are respectively fixedly arranged on both sides of the protective shell. The output ends of the two second cylinders respectively pass through the protective shell and are fixedly provided with suppression blocks. And both of the suppression blocks are arranged inside the protective shell. Suppression grooves are respectively opened at the bottom ends of one sides of the two suppression blocks close to the nozzle.

[0014] As a further improvement of the technical solution, triangular grooves are respectively opened at the top ends of one sides of the two suppression blocks close to the nozzle.

[0015] As a further improvement of the technical solution, a drain pipe is fixedly communicated with the outer wall of the protective shell at the lower part. A valve is fixedly installed on the surface of the drain pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the building concrete laser positioning wire saw for vibration suppression, the connection part between the guide wheel and the chain is covered by the protection mechanism, and an axial force is generated to make itself rotate, adapting to different cutting directions of the chain for concrete structure members such as reinforced concrete precast frames at different positions from multiple angles. And an oblique force is generated to make itself expand and contract, so as to adjust the protection range, so as to flexibly block the guide wheel and the chain in contact with the guide wheel, prevent the connection part between the guide wheel and the chain from getting involved in the clothes or hair of the approaching staff, eliminate potential safety hazards, and be beneficial to protecting the life and health of the staff.

[0018] 2. In the laser positioning wire saw for building concrete with vibration suppression, the water source is introduced into the protection mechanism by the operation of the flushing mechanism. Before the chain comes into contact with the guide wheel, the surface of the chain is flushed in advance to wash away debris such as concrete attached to the surface of the chain, so that it leaves the chain. Try to avoid the situation that after the chain contacts the guide wheel, debris such as concrete is sandwiched between the chain and the guide wheel, protecting the surfaces of the chain and the guide wheel from being damaged by the debris, which is beneficial to extending the service life of the chain and the guide wheel. Moreover, the flushing mechanism cooperates with the suppression mechanism. When the suppression mechanism reduces the vibration amplitude of the chain, due to the reduction of the vibration amplitude, the stability of the chain during rotation is improved. The suppression mechanism also reduces the water spray range of the flushing mechanism and speeds up the speed of the water spraying on the surface of the chain, better flushing the debris on the surface of the chain and taking away the heat generated due to the increased friction between the chain and the suppression mechanism, improving the cleaning effect. In addition, the flushing mechanism cooperates with the protection mechanism. The water sprayed by the flushing mechanism stays temporarily in the protection mechanism, so that the chain located below the guide wheel is immersed in the water source, and debris such as concrete that may remain on the surface of the chain is further washed off. When the chain leaving the protection mechanism contacts the component again for cutting, the damage to the surface of the chain can be further reduced, and the service life of the chain can be extended.

[0019] In addition to the purposes, features and advantages described above, the present invention has other purposes, features and advantages. The following will refer to the drawings to make a further detailed description of the present invention. Brief Description of the Drawings

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] The connection between the guide wheel and the chain is usually directly exposed to the working environment. When the staff observes the working conditions of the guide wheel and the chain, their clothes are easily entangled by the guide wheel and the chain, leading to safety accidents; since the chain is constantly rotating, the surface of the chain leaving the cutting area still has debris such as concrete. When the chain rotates onto the guide wheel, these debris attached to the chain will also contact the guide wheel, and the debris exerts destructive force on the chain and the guide wheel.

[0033] Therefore, the present invention provides a vibration-suppressed building concrete laser positioning wire saw. Please refer to Figures 1-9 , which includes a frame 1. A driving device 2 is installed on the top of the frame 1. A driving source is provided on the frame 1, which can drive the driving device 2 to move horizontally, such as Figure 7As shown, a laser locator is also provided on the surface of the driving device 2 for laser positioning of the cutting position of the building concrete. A guide wheel 3 is fixedly provided at the output end of the driving device 2. The driving device 2 includes a motor and a housing and other structures. The motor is installed in the housing. The output end of the motor is connected to the guide wheel 3. The rotation of the motor drives the guide wheel 3 to rotate. A chain 4 is connected to the surface of the guide wheel 3. The chain 4 is composed of a chain plate, a diamond bead, and a pin sleeve. The drive chain rotates at a high speed, and the diamond friction achieves the purpose of cutting the material. A protective mechanism 5 for covering the guide wheel 3 and the chain 4 is provided on the peripheral side of the guide wheel 3. The end of the chain 4 away from the driving device 2 is arranged on the outside of the protective mechanism 5. The protective mechanism 5 generates an axial force to make itself Rotate, adapt to the cutting direction of the chain 4 at multiple angles, and generate oblique force to make itself stretch and extend to adjust the protection range and form a cavity. A flushing mechanism 6 for cleaning the chain 4 is arranged on the top of the protection mechanism 5. The protection mechanism 5 and the flushing mechanism 6 are both connected to the driving device 2. The output end of the flushing mechanism 6 is arranged in the cavity, and cooperates with the cavity to receive the water source to immerse the chain 4 in the cavity. The two sides of the protection mechanism 5 are symmetrically provided with suppression mechanisms 7 for suppressing the vibration generated when the chain 4 is cut. The two suppression mechanisms 7 generate relative horizontal axial force to suppress the vibration amplitude of the chain 4, and change the flow range and direction of the water source sprayed by the flushing mechanism 6 to cooperate with the flushing mechanism 6 to change the water source flow rate, wherein:

[0034] The present invention Figures 1-3 As shown, considering that the connection between the guide wheel 3 and the chain 4 is usually directly exposed to the working environment, when the staff observes the working conditions of the guide wheel 3 and the chain 4, they need to get close to the connection between the guide wheel 3 and the chain 4 for observation. At this time, the clothes or hair of the staff are easily entangled by the guide wheel 3 and the chain 4, causing safety accidents. Therefore, Figure 1 As shown, the connection between the guide wheel 3 and the chain 4 is covered by the protection mechanism 5, and an axial force is generated to rotate itself, so as to adapt to the different cutting directions of the chain 4 on concrete structural members such as reinforced concrete prefabricated frames at different positions at multiple angles, and an oblique force is generated to stretch and extend itself to adjust the protection range, so as to flexibly shield the guide wheel 3 and the chain 4 in contact with the guide wheel 3, and prevent the connection between the guide wheel 3 and the chain 4 from being involved in the clothes or hair of the nearby staff, thereby eliminating safety hazards and protecting the life and health of the staff;

[0035] Since the chain 4 is constantly rotating, the surface of the chain 4 leaving the cutting position still has debris such as concrete. When the chain 4 rotates to the guide wheel 3, the debris attached to the chain 4 will also contact the guide wheel 3. The debris exerts a destructive force on both the chain 4 and the guide wheel 3, continuously damaging the surface of the guide wheel 3 and the chain 4, and reducing the service life of the guide wheel 3 and the chain 4. Therefore, if Figure 1As shown in the figure, the water source is introduced into the protection mechanism 5 by the operation of the flushing mechanism 6. Before the chain 4 comes into contact with the guide wheel 3, the surface of the chain 4 is flushed in advance, and debris such as concrete attached to the surface of the chain 4 is washed away to make it leave the chain 4. Try to avoid the situation that after the chain 4 comes into contact with the guide wheel 3, debris such as concrete is sandwiched between the chain 4 and the guide wheel 3, protecting the surfaces of the chain 4 and the guide wheel 3 from being damaged by debris, which is beneficial to extending the service life of the chain 4 and the guide wheel 3. Moreover, the flushing mechanism 6 cooperates with the suppression mechanism 7. When the suppression mechanism 7 reduces the vibration amplitude of the chain 4, due to the reduction of the vibration amplitude, the stability of the chain 4 during rotation is improved. At the same time, the suppression mechanism 7 reduces the water spray range of the flushing mechanism 6, speeds up the speed of the water spray on the surface of the chain 4, better flushes the debris on the surface of the chain 4, and takes away the heat generated due to the increased friction between the chain 4 and the suppression mechanism 7, improving the cleaning effect. In addition, the flushing mechanism 6 cooperates with the protection mechanism 5. The water source sprayed by the flushing mechanism 6 stays temporarily in the protection mechanism 5, so that the chain 4 located below the guide wheel 3 is immersed in the water source, and debris such as concrete that may remain on the surface of the chain 4 is further washed off. When the chain 4 leaving the protection mechanism 5 contacts the component again for cutting, the damage to the surface of the chain 4 can be further reduced, and the service life of the chain 4 is extended.

[0036] On the above basis, the specific structure is disclosed in detail:

[0037] To achieve that the protection mechanism 5 wraps the connection between the guide wheel 3 and the chain 4, preventing the guide wheel 3 and the chain 4 from getting caught in the clothes or hair of the staff and generating an axial force to make itself rotate, and adapting to the different cutting directions of the chain 4 for concrete structure components such as reinforced concrete precast frames at different positions from multiple angles, the specific structure of the protection mechanism 5 needs to be disclosed. Therefore, as Figure 4 shown, the protection mechanism 5 includes a fixed seat 51. One side of the fixed seat 51 close to the frame 1 is fixedly arranged on one side of the driving device 2. The side of the fixed seat 51 away from the frame 1 is fixedly provided with a protective shell 53 through a fastening bolt 52. And one end of the protective shell 53 away from the guide wheel 3 is set as an opening. The output end of the guide wheel 3, the flushing mechanism 6 and the output end of the suppression mechanism 7 are all arranged in the protective shell 53. The guide wheel 3 is completely blocked by the protective shell 53, and the connection between the guide wheel 3 and the chain 4 is blocked. In this way, it can prevent the guide wheel 3 from driving the chain 4 to rotate and getting caught in the clothes and hair of the nearby staff, improving the safety performance of the wire saw. When it is necessary for the protective shell 53 to generate an axial force to make itself rotate, loosen the fastening bolt 52, and the protective shell 53 can be rotated axially along the fixed seat 51. As Figure 6 shown, according to the different positions of concrete structure components such as reinforced concrete precast frames to be cut by the chain 4, the orientation of the opening of the protective shell 53 can be flexibly adjusted to flexibly block the guide wheel 3 and the part of the chain 4 in contact with the guide wheel 3, which is beneficial to improving the safety performance of the wire saw.

[0038] In order to realize that the protection mechanism 5 can adjust the protection range of the protection shell 53 according to the specific use needs to adapt to different safety protection requirements, it is necessary to further disclose the specific structure of the protection mechanism 5. Figure 4 As shown, a protective sleeve 54 is slidably provided at the opening of the protective shell 53, and one end of the protective sleeve 54 extends out of the protective shell 53 to adjust the protection range; the outer wall size of the protective sleeve 54 is adapted to the inner wall size of the protective shell 53, and the protective sleeve 54 slides along the inner wall of the protective shell 53, as shown in FIG. Figure 5 As shown, the protection range formed by the protective shell 53 and the protective sleeve 54 is reduced or expanded, so that the protection range of the protective shell 53 can be flexibly adjusted according to the use requirements of the wire saw to adapt to different safety protection requirements.

[0039] In order to realize that the protective sleeve 54 can move along the inner wall of the protective shell 53, the protective mechanism 5 needs to generate an oblique force to make the protective range formed by the protective shell 53 and the protective sleeve 54 expand and contract. Therefore, the specific structure of the protective mechanism 5 needs to be further developed. Figure 4 As shown, the first fixed blocks 55 are symmetrically fixed on one end of the top and bottom of the protective shell 53, the first cylinders 56 are fixedly provided on the side of the two first fixed blocks 55 away from the guide wheel 3, the second fixed blocks are fixedly provided on the output ends of the two first cylinders 56, and the bottom ends of the two second fixed blocks are respectively fixedly connected to the top and bottom of the protective sleeve 54. The first cylinders 56 are extended and retracted to generate an oblique force, which drives the protective sleeve 54 to move along the inner wall of the protective shell 53, thereby changing the protection range composed of the protective shell 53 and the protective sleeve 54 to meet the different protection requirements of the wire saw.

[0040] In order to realize that the flushing mechanism 6 flushes the surface of the chain 4 before the chain 4 contacts the guide wheel 3, to avoid as much as possible that debris such as concrete is mixed between the chain 4 and the guide wheel 3 after the chain 4 contacts the guide wheel 3, and to protect the surface of the chain 4 and the guide wheel 3 from being damaged by the debris, it is necessary to disclose the specific structure of the flushing mechanism 6. Figure 4 As shown, the flushing mechanism 6 includes a nozzle 61, which is fixedly arranged at the other end of the top of the protective shell 53, and the output end of the nozzle 61 is located inside the protective shell 53, corresponding to the chain 4. Water is sprayed out through the nozzle 61, and the water quickly flushes on the surface of the chain 4, cleaning the concrete and other debris on the surface of the chain 4 that is about to contact the guide wheel 3, so that the debris leaves the chain 4, avoiding the concrete and other debris being mixed between the chain 4 and the guide wheel 3 after the chain 4 contacts the guide wheel 3, protecting the surface of the chain 4 and the guide wheel 3 from being damaged by the debris, thereby extending the service life of the chain 4 and the guide wheel 3.

[0041] Among them, a driving force is required to pump the water source into the nozzle 61, so that the water source can be sprayed from the nozzle 61 to the surface of the chain 4 to wash away the concrete and other debris, so it is necessary to continue to disclose the specific structure of the flushing mechanism 6. Therefore,Figure 4 As shown, the flushing mechanism 6 further includes a water pump 62. The bottom of the water pump 62 is fixedly arranged on the top of the driving device 2. The output end of the water pump 62 is fixedly communicated with a hose 63. One end of the hose 63 away from the water pump 62 is fixedly communicated with a conduit 64. One end of the conduit 64 away from the water pump 62 is fixedly communicated with the input end of the nozzle 61. By connecting an external water source to the water pump 62, the water pump 62 generates power to pump the water source into the space between the hose 63 and the conduit 64. The water source flows through the hose 63 and the conduit 64 and enters the nozzle 61, and then sprays from the nozzle 61 onto the chain 4 to wash away debris such as concrete on the surface of the chain 4. And the water source after flushing temporarily stays in the protective shell 53, submerging a part of the chain 4 in contact with the guide wheel 3, so that debris such as concrete that may remain on the surface of the chain 4 can be further washed off. When the chain 4 leaving the protection mechanism 5 contacts the component again for cutting, the damage to the surface of the chain 4 can be further reduced, and the service life of the chain 4 can be further extended.

[0042] Among them, if the suppression mechanism 7 is required to suppress the abnormal vibration amplitude generated by the chain 4 as needed, the specific structure of the suppression mechanism 7 needs to be disclosed. Therefore, as Figure 8 shown, both suppression mechanisms 7 include second cylinders 71. The end covers of the two second cylinders 71 are respectively fixedly arranged on both sides of the protective shell 53. The output ends of the two second cylinders 71 respectively pass through the protective shell 53 and are fixedly provided with suppression blocks 72, and both suppression blocks 72 are arranged inside the protective shell 53. Suppression grooves 73 are respectively opened at the bottom ends of the two suppression blocks 72 on the side close to the nozzle 61. By the telescopic movement of the two second cylinders 71 to drive the two suppression blocks 72 to move relatively, and then drive the two suppression grooves 73 to move relatively. As Figure 8 shown, approaching the rotating and vibrating chain 4 to limit the vibration amplitude of the chain 4.

[0043] Among them, if the suppression block 72 is required to reduce the spraying range of the water source sprayed by the nozzle 61, accelerate the speed of the water source spraying on the surface of the chain 4, and better wash the debris on the surface of the chain 4, the specific structure of the suppression mechanism 7 needs to be further disclosed. Therefore, as Figure 8 shown, triangular grooves 74 are respectively opened at the top ends of the two suppression blocks 72 on the side close to the nozzle 61. By the movement of the suppression block 72 approaching the nozzle 61, the water source sprayed by the nozzle 61 impacts on the triangular grooves 74 and continues to flow downward rapidly along the surface of the triangular grooves 74, and impacts on the chain 4 at a faster speed to wash away debris such as concrete on the chain 4.

[0044] Among them, if the water source staying in the protective shell 53 for further cleaning the chain 4 needs to intermittently carry debris such as concrete away from the protective shell 53, the specific structure of the protection mechanism 5 needs to be further developed. Therefore, as Figure 4As shown, a drain pipe 57 is fixedly connected to the outer wall of the protective shell 53 at the lower part. A valve is fixedly installed on the surface of the drain pipe 57. By intermittently opening and closing the valve, the water source remaining in the protective shell 53 carries debris such as concrete deposited at the bottom of the inner wall of the protective shell 53 and leaves the protective shell 53 via the drain pipe 57.

[0045] In summary, the overall working principle of the present invention is as follows:

[0046] When the wire saw needs to be used to cut concrete structure members such as reinforced concrete precast frames, first adjust the angles of the protective shell 53 and the protective sleeve 54. Loosen the fastening bolts 52, and then the protective shell 53 and the protective sleeve 54 can be rotated along the axial direction of the fixed seat 51. According to the different positions of the concrete structure members such as the reinforced concrete precast frames to be cut by the chain 4, the orientation of the opening of the protective shell 53 can be flexibly adjusted. Then, the chain 4 is sleeved on the position of the member to be cut. Then, through the self-expansion and contraction of the first cylinder 56, an oblique force is generated to drive the protective sleeve 54 to move along the inner wall of the protective shell 53, thereby changing the protection range formed by the protective shell 53 and the protective sleeve 54. Start the driving device 2 to drive the guide wheel 3 to rotate. Note that the rotation direction of the guide wheel 3 is counterclockwise, and then drive the chain 4 to rotate counterclockwise to cut the position of the member that needs to be cut;

[0047] Flush the surface of the chain 4 that is about to contact the guide wheel 3. Start the water pump 62. The water pump 62 generates power to pump the water source into the space between the hose 63 and the conduit 64. The water source flows through the hose 63 and the conduit 64 and enters the nozzle 61, and then sprays out from the nozzle 61 onto the chain 4 to wash away debris such as concrete on the surface of the chain 4. And the water source after flushing temporarily remains in the protective shell 53, submerging a part of the chain 4 that contacts the guide wheel 3, so that debris such as concrete that may remain on the surface of the chain 4 is further washed off;

[0048] When the chain vibrates abnormally and significantly, start the second cylinder 71, and make it expand and contract to drive the two suppression blocks 72 to move relatively, and then drive the two suppression grooves 73 to move relatively closer to the chain 4, suppressing and reducing the vibration amplitude of the chain 4. The water source sprayed out by the nozzle 61 impacts on the triangular groove 74 and continues to flow downward rapidly along the surface of the triangular groove 74, and impacts on the chain 4 at a faster speed to wash away debris such as concrete on the chain 4.
