Description

Technical Field

[0001] The present invention relates to the technical field of concrete processing, and particularly to a cutting device for concrete structural members. Background Art

[0002] A concrete structure refers to a load-bearing structure system formed by mixing materials such as cement, sand (fine aggregate), gravel (coarse aggregate), water, and additives in proportion, and then undergoing stirring, pouring, and curing and hardening. Due to its versatility, economy, and wide applicability, the concrete structure has become the core material in modern engineering construction.

[0003] In the related art, in order to prevent the ash-water mixture generated during the cutting of concrete components from being thrown into the inside of the cutting machine housing and solidifying, which affects the normal use of the cutting equipment. For example, the patent with the publication number CN212602624U in the prior art provides a concrete slicing machine for engineering construction. This device connects two fixing pins through fixing bolts. During the cutting process, the first protective cover and the second protective cover together form a protective cover to prevent the blade from harming the staff. Since the blade is likely to throw the water body with dust into the inside of the protective housing and condense into a solid block, after the cutting is completed, the fixing bolts are loosened and the second protective cover is rotated to separate it, so that the inside of the protective cover can be cleaned without disassembling the blade and the protective cover, improving the maintenance efficiency.

[0004] Although the above-mentioned prior art solution can block the water-cement mixture by detachably arranging the second protective cover outside the blade, and clean the accumulated mixture by disassembling the second protective cover, in order to ensure the cutting depth of the blade, the first protective cover and the second protective cover are usually set at a fixed height. When the blade starts to cut the concrete component, since the protective structure is far from the cutting surface, the protective structure cannot block the generated water-cement mixture at the beginning of cutting, and there is a defect of poor protection effect during the cutting of the concrete component.

[0005] In view of this, we have proposed a cutting device for concrete structural members. Summary of the Invention

Specifically, the motor A22 is fixedly arranged inside the outer shell 57.

[0050] As a specific implementation manner, the three-axis drive assembly 5 includes an arc-shaped limiting plate 58.

[0051] The arc-shaped limiting plate 58 is slidably arranged on the outside of the enclosing plate 12; the inner side of the arc-shaped limiting plate 58 is in sliding fit with the outer surface of the enclosing plate 12; On the tops of the enclosing plate 12 and the arc-shaped limiting plate 58, a jack A14 and a jack B59 are respectively provided. A pin 15 is inserted inside the jack A14 and the jack B59.

[0052] Specifically, on the side where the enclosing plate 12 rotates downward by itself, an inclined surface B16 is provided. At the bottom of the pin 15, an inclined surface A151 is provided corresponding to the inclined surface B16.

[0053] Specifically, the central angles corresponding to the side plate A11 and the enclosing plate 12 are greater than 180°. The inner side of the arc-shaped limiting plate 58 is in sliding fit with the outer surface of the enclosing plate 12, so that when the fixed protection assembly 1 is upwardly open, both sides of the fixed protection assembly 1 are located inside the arc-shaped limiting plate 58. Under the action of the arc-shaped limiting plate 58, the fixed protection assembly 1 is supported, preventing the fixed protection assembly 1 from being damaged due to the vibration caused by the water, sediment, the spraying assembly 3 and the moving protection assembly 4 carried inside during the cleaning process, and improving the stability of the use safety.

[0054] Specifically, the water-cement mixture drives the fixed protection assembly 1 to rotate to the upwardly open state by its own gravity to serve as a cleaning container.

[0055] To further illustrate the principle and advantages of the concrete structure member cutting device provided by the embodiments of the present application, the specific working principle is as follows: First, the guide rail assembly 51 is arranged in the cutting direction. By sliding the electric slide 52 on the top of the guide rail assembly 51, the cutting blade 2 can be driven to the cutting position. During the cutting process, by continuously moving the electric slide 52, cutting can be performed along the X-axis direction, and by driving the fixed protection assembly 1 to lift through the hydraulic drive assembly B55, different cutting depths can be achieved to ensure that the concrete member is cut off.

[0056] After a cutting seam is cut, the fixed protection component 1 is pushed to move horizontally by the hydraulic drive component A53, so as to move the cutting blade 2 to another parallel cutting position. Finally, the direction of the guide rail component 51 is adjusted to perform cutting in other directions.

[0057] Specifically, during continuous cutting, water is supplied into the water supply pipe 313 by an external water supply device, so that the water source is input into the inside of the sealing disc 38 through the water supply pipe 313, and then input into the inside of the annular disc 35 through the communication hole B310 on the inner side of the sealing plate 39. It is input into the inside of one of the spray pipes 33 through the communication hole A37 inside the annular disc 35, and finally input into the inside of the other spray pipe 33 through the U-shaped connector 31. The water source can be sprayed outside the cutting blade 2 through the nozzles 34 externally connected to the two spray pipes 33 at the same time for cooling, preventing the temperature of the cutting blade 2 from being too high during the cutting process.

[0058] At the same time, the water source is mixed with the dust generated by the cutting of the cutting blade 2, and the generated slurry is thrown out towards the inside of the moving protection component 4 under the action of the cutting blade 2. Under the action of the moving protection component 4, it can prevent the slurry from being thrown out on a large scale and causing unnecessary pollution. And as the cutting depth of the cutting blade 2 changes, the motor B7 drives the driving gear 71 to rotate, so that the driving gear 71 drives the driven gear 312 to rotate, and then drives the annular disc 35 to rotate, so that the annular disc 35 drives the support plate 32 to rotate inside the fixed protection component 1, and then drives the bottom of the arc-shaped shield 41 to gradually move upward, realizing effective shielding of the slurry.

[0059] Specifically, the spray component 3 drives the moving protection component 4 to slide inside the fixed protection component 1, so that the bottom of the moving protection component 4 can move upward following the cutting depth of the cutting blade 2, so that the cutting opening generated by the cutting blade 2 during the cutting process always maintains a certain distance from the moving protection component 4, realizing effective shielding of the slurry to achieve the effect of improving protection; and driven by the spray component 3, the moving protection component 4 can slide greatly inside the fixed protection component 1, so that the moving protection component 4 cleans the inner wall of the fixed protection component 1 during the sliding process, preventing the accumulation of slurry particles on the inner side of the fixed protection component 1 from caking and bringing inconvenience to the later cleaning work.

[0060] In addition, when cleaning the fixed protection component 1 and the moving protection component 4 in the concrete structure member cutting device of the present application, by pulling out the pin 15 at the top of the fixed protection component 1 and the arc-shaped limiting plate 58, the pin 15 releases the locking of the fixed protection component 1. At this time, the moving protection component 4 on one side of the fixed protection component 1 causes it to deflect, and then drives the entire fixed protection component 1 to rotate, so as to adjust the opening of the fixed protection component 1 to the upward state.

[0061] Then, water is sprayed to the outside of the cutting blade 2 through the spraying component 3, and the water flow will flow downward along the outside of the cutting blade 2 into the interior of the fixed protection component 1, using the fixed protection component 1 as a water container; then the spraying component 3 is driven to rotate by the motor B7 outside the side plate B13, so that the spraying component 3 drives the movable protection component 4 to slide inside the fixed protection component 1. During the sliding process, the friction plate 43 located outside the arc-shaped shield 41 is tightly attached to the inner wall of the fixed protection component 1 under the action of the elastic piece 42, and is elastically pressed, so that the mud particles on the inner wall of the fixed protection component 1 can be cleaned by the friction plate 43 during the rotation of the arc-shaped shield 41. When the arc-shaped shield 41 rotates a certain angle, it will gradually approach the cleaning component 6, and finally the friction block 61 is elastically pressed against the inside of the arc-shaped shield 41 under the action of the spring 62, so that the arc-shaped shield 41 cleans its own inside during rotation to prevent the mud inside the arc-shaped shield 41 from accumulating and caking.

[0062] When the arc-shaped shield 41 drives the friction plate 43 to rotate repeatedly for a certain period, the driving shaft 23 is driven to rotate by the motor A22, so that the driving shaft 23 drives the cutting blade 2 to rotate in the direction opposite to the cutting direction. At this time, the driving shaft 23 drives the outer ring of the one-way bearing 24 to rotate, so that the driving shaft 23 drives the connecting block 19 to make a circular motion through the one-way bearing 24, and then drives the fixed protection component 1 to rotate outside the housing 57 through the connecting block 19.

[0063] When the inclined surface B16 on one side of the fixed protection component 1 approaches the bottom of the plug 15, the inclined surface B16 first approaches the bottom of the inclined surface A151. Under the extrusion of the fixed protection component 1, the plug 15 is lifted upward. When the fixed protection component 1 drives the jack A14 to be directly below the plug 15, the plug 15 automatically inserts into the interior of the jack A14 under its own gravity to lock the fixed protection component 1, so as to facilitate the reset of the fixed protection component 1 after cleaning; and during the process of the fixed protection component 1 rotating and resetting, the waste water generated by cleaning inside the fixed protection component 1 can be automatically discharged, and by continuously driving the spraying component 3 to rotate reciprocally by the motor B7, the spraying component 3 can continuously spray water to the inside of the fixed protection component 1 and the outside of the cutting blade 2 during the reset process of the fixed protection component 1, so as to automatically wash the fixed protection component 1 and the cutting blade 2 during the reset process of the fixed protection component 1, so as to clean the sediment and impurities generated by cleaning.

[0064] It should be noted that the above cleaning method has the following advantages: Advantage 1, when cleaning the inside of the fixed protection component 1, only need to pull out the plug 15, then the fixed protection component 1 can automatically turn over by relying on the gravity of the movable protection component 4, making the opening of the fixed protection component 1 face upward as a water container to ensure the cleaning effect.

[0065] Advantage two: After the fixed protection component 1 is cleaned, the drive shaft 23 is driven by the motor A22 to rotate in the reverse direction (relative to the rotation direction of the cutting blade 2), so that the drive shaft 23 drives the fixed protection component 1 to automatically rotate and reset through the connecting block 19 arranged on the outer ring of the one-way bearing 24, making it more convenient to use.

[0066] Advantage three: In order to ensure the stability of the fixed protection component 1 after resetting, an inclined surface B16 is provided on one side of the fixed protection component 1. When the inclined surface B16 on one side of the fixed protection component 1 approaches the bolt 15, the inclined surface B16 first approaches the bottom of the inclined surface A151. Finally, under the interaction of the inclined surface B16 and the inclined surface A151, the bolt 15 is pushed upward. When the fixed protection component 1 drives the jack A14 to be directly below the bolt 15, the bolt 15 automatically inserts into the inside of the jack A14 under its own gravity to realize automatic locking of the fixed protection component 1, further improving the convenience of use.

[0067] Advantage four: When cleaning the inner side of the fixed protection component 1, the spray component 3 drives the movable protection component 4 to slide inside the fixed protection component 1. The friction plate 43 elastically arranged on the outer side of the arc-shaped cover 41 can be used to clean the inner side of the fixed protection component 1. During the cutting process of the cutting blade 2, the movable protection component 4 effectively blocks the mud under the drive of the spray component 3. Furthermore, by changing the motion state of the spray component 3, it can be used for different working conditions, reducing the cleaning cost and improving the cleaning efficiency.

[0068] Advantage five: When the fixed protection component 1 rotates and resets under the drive of the motor A22, the opening of the fixed protection component 1 gradually rotates and tilts, so as to automatically clean the sediment and water generated during the internal cleaning, further improving the cleaning efficiency.

[0069] Advantage six: During the rotation and reset process of the fixed protection component 1, the motor B7 drives the spray component 3 to rotate reciprocally, so that the spray component 3 always sprays water towards its inner side and the outer side of the cutting blade 2 during the tilting process of the fixed protection component 1, so as to wash away the residual sediment and impurities on the surface and make the cleaning of the equipment more thorough.

[0070] Advantage seven: During the process of the spray component 3 driving the movable protection component 4 to move, the arc-shaped cover 41 automatically cooperates with the cleaning component 6 inside the fixed protection component 1, and can realize its own cleaning while cleaning the inner side of the fixed protection component 1, preventing the sediment accumulated on the inner side of the arc-shaped cover 41 from caking and affecting subsequent use.

[0071] In practical applications, lubrication needs to be maintained between the bolt 15 and the jack A14 and the jack B59. To ensure the stability of the sliding reset of the bolt 15, lubricating oil needs to be added to the inside of the jack B59 and the jack A14 before each cleaning. And to ensure that the inclined plane A151 at the bottom of the bolt 15 faces the inclined plane B16, the jack B59 at the top of the arc-shaped limiting plate 58 is slidably arranged to ensure that the bolt 15 can only slide vertically along the axis.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
