Description

Technical Field

[0001] The invention relates to the technical field of civil engineering and construction engineering, in particular to a vibration-suppressed construction concrete laser positioning wire saw. Background Art

[0002] Concrete structural components such as reinforced concrete precast frames refer to load-bearing building components made of a combination of concrete and steel bars that are prefabricated through industrial production. During the construction process, wire saw technology is mainly used in the later correction and precision forming stages. For non-standard prefabricated parts such as curved beams and curved floor slabs, wire saws can achieve correction of complex geometric shapes that are difficult to form with traditional molds through three-dimensional cutting.

[0003] Currently, existing wire saws have the following defects when in use:

[0004] First, existing wire saws generally use a drive source to drive a guide wheel connected to it to rotate. The rotation of the guide wheel drives the chain to rotate by friction transmission. The chain rotates to cut and correct concrete structural components such as reinforced concrete precast frames. However, the connection between the guide wheel and the chain is usually directly exposed to the working environment. When workers observe the working conditions of the guide wheel and chain, their clothes can easily be entangled in the guide wheel and chain, causing safety accidents.

[0005] Secondly, when the chain is cutting concrete structural components such as reinforced concrete precast frames, the cutting point between the chain and the component is generally cooled with cold water to reduce friction heat and extend the life of the chain. However, since the chain is constantly rotating, the surface of the chain leaving the cutting point still carries debris such as concrete. When the chain rotates to the guide wheel, these debris attached to the chain will also come into contact with the guide wheel. The debris exerts destructive force on the chain and the guide wheel, and continuously damages the surface 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 vibration-suppressed construction concrete laser positioning wire saw. Summary of the Invention

[0006] The object of the present invention is to provide a vibration-suppressed construction concrete laser positioning wire saw, which covers the connection between the guide wheel and the chain through a protective mechanism to generate axial force, adapt to the chain cutting direction at multiple angles, and generate oblique force to make itself retract and extend, so as to adjust the protection range and prevent the connection between the guide wheel and the chain from being entangled in the clothes or hair of the nearby workers; the water source is introduced into the protective mechanism through the operation of the flushing 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, the stability of the chain during rotation is improved due to the reduction in vibration amplitude.

Suppression mechanisms for suppressing the vibration generated when the chain is cut are symmetrically provided 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 the side of the driving device close to the frame, and a protective shell is fixedly arranged on the side of the fixed seat away from the frame by fastening bolts, and the end of the protective shell away from the guide wheel is set to 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 this 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.

[0014] As a further improvement of the present technical solution, triangular grooves are provided on the tops of the two suppression blocks on the side close to the nozzle.

[0015] As a further improvement of the present technical solution, the outer wall of the protective shell at the bottom is fixedly connected to a drain pipe, and a valve is fixedly installed on the surface of the drain pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this vibration-suppressed construction concrete laser positioning wire saw, the connection between the guide wheel and the chain is covered by a protective mechanism, and an axial force is generated to rotate the saw itself, adapting to the different cutting directions of the chain on concrete structural members such as reinforced concrete prefabricated frames at different positions at multiple angles. The saw also generates an oblique force to cause it to retract and extend itself to adjust the protection range, so as to flexibly shield the guide wheel and the chain in contact with the guide wheel, and prevent the connection between the guide wheel and the chain from being caught in the clothes or hair of nearby workers, thereby eliminating safety hazards and protecting the lives and health of workers.

[0018] 2. In the vibration-suppressed construction concrete laser positioning wire saw, the water source is introduced into the protective mechanism through the operation of the flushing mechanism. Before the chain contacts the guide wheel, the surface of the chain is flushed in advance to flush the concrete and other debris attached to the chain surface to make it leave the chain, and to avoid concrete and other debris being mixed between the chain and the guide wheel after the chain contacts the guide wheel, thereby protecting the surface 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. The flushing mechanism cooperates with the suppression mechanism. When the suppression mechanism reduces the vibration amplitude of the chain, the stability of the chain during rotation is improved due to the reduction of the vibration amplitude, and the suppression mechanism The structure simultaneously narrows the water source spray range of the flushing mechanism, speeds up the water source spraying on the chain surface, better washes the debris on the chain surface, and takes away the heat generated by the increased friction between the chain and the inhibition mechanism, thereby improving the cleaning effect. The flushing mechanism cooperates with the protective mechanism, and the water source sprayed by the flushing mechanism temporarily stays in the protective mechanism, so that the chain under the guide wheel is immersed in the water source, so that the concrete and other debris that may be retained on the chain surface can be further cleaned off, so that when the chain that leaves the protective mechanism contacts the component again for cutting, the damage to the chain surface can be further reduced, thereby extending the service life of the chain.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection 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, causing safety accidents; since the chain is constantly rotating, the surface of the chain leaving the cutting point still has debris such as concrete. When the chain rotates to the guide wheel, these debris attached to the chain will also come into contact with the guide wheel, and the debris will exert destructive force on the chain and the guide wheel.

[0033] To this end, the present invention provides a vibration-suppressed construction concrete laser positioning wire saw, see Figures 1-9 , which includes a frame 1, a driving device 2 is installed on the top of the frame 1, and a driving source is set on the frame 1, which can drive the driving device 2 to move in the horizontal direction, 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 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 provided on the top of the protection mechanism 5. The protection mechanism 5 and the flushing mechanism 6 are both connected to the drive device 2. The output end of the flushing mechanism 6 is provided in the cavity, and cooperates with the cavity to receive the water source to immerse the chain 4 in the cavity. The protection mechanism 5 is symmetrically provided with a suppression mechanism 7 on both sides for suppressing the vibration generated when the chain 4 is cut. The two suppression mechanisms 7 generate a 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 Figure 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 staff's clothes or hair 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 the chain 4, 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 make the chain 4 stretch and extend 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 caught in the clothes or hair of the nearby workers, thereby eliminating safety hazards and protecting the lives and health of the workers.

[0035] Moreover, 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, these debris attached to the chain 4 will also come into contact with 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, thereby reducing the service life of the guide wheel 3 and the chain 4. Therefore, if Figure 1As shown, the water source is introduced into the protective mechanism 5 through 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 to flush the concrete and other debris attached to the surface of the chain 4 to make it leave the chain 4, and to avoid as much as possible that the concrete and other debris are mixed between the chain 4 and the guide wheel 3 after the chain 4 comes into contact with the guide wheel 3, thereby protecting the surface of the chain 4 and the guide wheel 3 from being damaged by the debris, which is beneficial to extending the service life of the chain 4 and the guide wheel 3, and the flushing mechanism 6 cooperates with the suppression mechanism 7. When the suppression mechanism 7 reduces the vibration amplitude of the chain 4, the stability of the chain 4 during rotation is improved due to the reduction in the vibration amplitude, and the suppression mechanism 7 also reduces the impact of the flushing mechanism 6. The water source spraying range of the washing mechanism 6 speeds up the speed of the water source spraying on the surface of the chain 4, better washes the debris on the surface of the chain 4, and takes away the heat generated by the increased friction between the chain 4 and the suppression mechanism 7, thereby improving the cleaning effect. The washing mechanism 6 cooperates with the protective mechanism 5, and the water source sprayed by the washing mechanism 6 temporarily stays in the protective mechanism 5, so that the chain 4 located below the guide wheel 3 is immersed in the water source, so that the concrete and other debris that may be retained on the surface of the chain 4 can be further washed off, so that when the chain 4 leaving the protective mechanism 5 contacts the component again for cutting, the damage to the surface of the chain 4 can be further reduced, thereby extending the service life of the chain 4.

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

[0037] In order to realize that the protection mechanism 5 covers the connection between the guide wheel 3 and the chain 4, prevents the guide wheel 3 and the chain 4 from being caught in the clothes or hair of the staff, and generates axial force to rotate itself, and adapts 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, the specific structure of the protection mechanism 5 must be disclosed. Therefore, Figure 4 As shown, the protective mechanism 5 includes a fixing base 51, and the side of the fixing base 51 close to the frame 1 is fixedly arranged on the side of the driving device 2, and the side of the fixing base 51 away from the frame 1 is fixedly provided with a protective shell 53 by a fastening bolt 52, and the end of the protective shell 53 away from the guide wheel 3 is set to be open, and the guide wheel 3, the output end of 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 shielded by the protective shell 53, and the connection between the guide wheel 3 and the chain 4 is shielded. In this way, the guide wheel 3 can be prevented from driving the chain 4 to rotate and entangle the clothes and hair of the nearby staff, thereby improving the safety performance of the wire saw. When the protective shell 53 is needed to generate axial force to rotate itself, the fastening bolt 52 is loosened, and the protective shell 53 can be rotated along the axial direction of the fixing base 51. Figure 6 As shown, the direction of the opening of the protective shell 53 is flexibly adjusted according to the different positions of the reinforced concrete prefabricated frame and other concrete structural components to be cut by the chain 4, so as 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 interior of the protective shell 53 to adjust the range of protection; 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 of 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 composed of 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 at one end of the top and bottom of the protective shell 53, and the first cylinders 56 are fixedly provided on the side of the two first fixed blocks 55 away from the guide wheel 3. The output ends of the two first cylinders 56 are fixedly provided with second fixed blocks, 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 stretched 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 adapt to 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, and to avoid concrete and other debris being 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. Therefore, as shown in FIG. 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 through the nozzle 61, and the water quickly flushes 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 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, and 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, and the water source can be sprayed from the nozzle 61 to the surface of the chain 4 to flush the concrete and other debris. It is necessary to continue to disclose the specific structure of the flushing mechanism 6. Therefore, Figure 4 As shown, the flushing mechanism 6 also includes a water pump 62, the bottom of the water pump 62 is fixedly arranged on the top of the driving device 2, and the output end of the water pump 62 is fixedly connected to a hose 63, and the end of the hose 63 away from the water pump 62 is fixedly connected to a conduit 64, and the end of the conduit 64 away from the water pump 62 is fixedly connected to the input end of the nozzle 61. The water source is connected to the water pump 62, and 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 into the nozzle 61, and then is sprayed from the nozzle 61 to the chain 4, flushing the concrete and other debris on the surface of the chain 4, and the water source after flushing temporarily stays in the protective shell 53, immersing a part of the chain 4 in contact with the guide wheel 3, so that the concrete and other debris that may be retained on the surface of the chain 4 can be further cleaned off, so that when the chain 4 that leaves the protective 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, the suppression mechanism 7 is required to suppress the abnormal vibration amplitude of the chain 4 as needed, so the specific structure of the suppression mechanism 7 needs to be disclosed. Figure 8 As shown, the two suppression mechanisms 7 each include a second cylinder 71, and the end covers of the two second cylinders 71 are fixedly arranged on both sides of the protective shell 53. The output ends of the two second cylinders 71 are respectively fixed with suppression blocks 72 passing through the protective shell 53, and the two suppression blocks 72 are both arranged in the protective shell 53. The bottom ends of the two suppression blocks 72 on the side close to the nozzle 61 are each provided with a suppression groove 73. The two second cylinders 71 are extended and retracted to drive the two suppression blocks 72 to move relative to each other, thereby driving the two suppression grooves 73 to move relative to each other, as shown in FIG. Figure 8 As shown, the chain 4 is close to the rotating and vibrating chain 4, limiting the vibration amplitude of the chain 4.

[0043] Among them, in order to enable the suppression block 72 to reduce the spray range of the water source sprayed by the nozzle 61, speed up the speed of the water source spraying on the surface of the chain 4, and better wash away the debris on the surface of the chain 4, it is necessary to further disclose the specific structure of the suppression mechanism 7. Therefore, as Figure 8 As shown, a triangular groove 74 is provided at the top of each of the two suppression blocks 72 close to the nozzle 61. When the suppression block 72 moves close to the nozzle 61, the water sprayed from the nozzle 61 hits the triangular groove 74, continues to flow downward along the surface of the triangular groove 74, and impacts the chain 4 at a faster speed, washing away concrete and other debris on the chain 4.

[0044] Among them, the water source retained in the protective shell 53 for further cleaning the chain 4 needs to intermittently carry debris such as concrete out of the protective shell 53, so it is necessary to continue to expand the specific structure of the protective mechanism 5. Therefore, if Figure 4As shown, the outer wall of the protective shell 53 at the bottom is fixedly connected to a drain pipe 57, and a valve is fixedly installed on the surface of the drain pipe 57. By intermittently opening and closing the valve, the water source retained in the protective shell 53 carries the concrete and other debris deposited on the bottom of the inner wall of the protective shell 53 out of the protective shell 53 through the drain pipe 57.

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

[0046] When it is necessary to use the wire saw to cut concrete structural components such as reinforced concrete prefabricated frames, the angles of the protective shell 53 and the protective sleeve 54 are first adjusted, and the fastening bolts 52 are loosened, and the protective shell 53 and the protective sleeve 54 can be rotated along the axial direction of the fixing seat 51. The direction of the opening of the protective shell 53 is flexibly adjusted according to the different positions of the reinforced concrete prefabricated frames and other concrete structural components to be cut by the chain 4, and then the chain 4 is put on the position of the component to be cut. Then, the first cylinder 56 is stretched and contracted 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 formed by the protective shell 53 and the protective sleeve 54, and starting the driving device 2 can drive the guide wheel 3 to rotate. Note that the rotation direction of the guide wheel 3 is counterclockwise, thereby driving the chain 4 to rotate counterclockwise to cut the position where the component needs to be cut;

[0047] The surface of the chain 4 that is about to come into contact with the guide wheel 3 is rinsed by starting the water pump 62. The water pump 62 generates power to pump water into the space between the hose 63 and the conduit 64. The water flows through the hose 63 and the conduit 64 and enters the nozzle 61. The water is then sprayed from the nozzle 61 onto the chain 4 to rinse concrete and other debris on the surface of the chain 4. The water after rinsing is temporarily retained in the protective shell 53, submerging the portion of the chain 4 that is in contact with the guide wheel 3, so that concrete and other debris that may be retained on the surface of the chain 4 can be further cleaned.

[0048] When the chain vibrates abnormally and greatly, the second cylinder 71 is started to expand and contract, driving the two suppression blocks 72 to move relative to each other, and then driving the two suppression grooves 73 to move relative to each other and approach the chain 4, thereby suppressing and reducing the vibration amplitude of the chain 4. The water source sprayed by the nozzle 61 hits the triangular groove 74, continues to flow downward rapidly along the surface of the triangular groove 74, and impacts the chain 4 at a faster speed, washing away the concrete and other debris on the chain 4.

The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
