Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete processing, in particular to a concrete structure component cutting device. BACKGROUND

[0002] The concrete structure refers to a load-bearing structure system formed by mixing cement, sand (fine aggregate), gravel (coarse aggregate), water and other materials in proportion, and then stirring, pouring and curing and hardening; the concrete structure has become the core material of modern engineering construction due to its multifunctionality, economy and wide applicability.

[0003] In related technologies, in order to prevent the water and ash mixture generated during the cutting of the concrete component from being thrown into the cutting machine shell and solidified to affect the normal use of the cutting equipment, for example, the prior art with the publication number CN212602624U provides a concrete slicing machine for engineering construction, which connects two fixed pins by fixed bolts, and in the cutting process, the first protective cover and the second protective cover jointly form a protective cover to prevent the blade from causing harm to the workers; since the blade can easily throw the water containing dust into the protective shell and solidify into a solid block, after the cutting is completed, the fixed bolts are twisted to rotate the second protective cover to separate it, so that the inside of the protective cover can be cleaned without the need to disassemble the blade and the protective cover, thereby improving the maintenance efficiency.

[0004] Although the prior art in the above can achieve the effect of blocking the water and ash mixture by detachably arranging the second protective cover outside the blade, and cleaning the accumulated mixture by detaching 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 arranged at a fixed height; when the blade starts to cut the concrete component, since the protective structure is far away from the cutting surface, the protective structure cannot block the water and ash mixture generated at the beginning of the cutting, and there is a defect that the protection effect is poor during the cutting of the concrete component.

[0005] In view of this, we propose a concrete structure component cutting device. SUMMARY

[0105] Specifically, the corresponding central angle of the side plate A11 and the surrounding plate 12 is greater than 180°, and the inner side of the arc-shaped limiting plate 58 is in sliding fit with the outer surface of the surrounding plate 12, so that when the opening is upward, the two sides of the fixed protection assembly 1 are located on the inner side of the arc-shaped limiting plate 58, and the fixed protection assembly 1 is supported under the action of the arc-shaped limiting plate 58, preventing the fixed protection assembly 1 from being damaged due to internal bearing water and silt and vibration caused by the spraying assembly 3 and the moving protection assembly 4 during cleaning, and improving the stability of use safety.

[0106] Specifically, the water and cement mixture is driven to rotate to the opening upward state by its own gravity, as a cleaning container.

[0107] To further illustrate the principle and advantages of the concrete structure member cutting device provided by the embodiments of the application, the specific working principle is as follows:

[0108] First, the guide rail assembly 51 is arranged in the cutting direction, and the cutting blade 2 is driven to be located at the cutting position by the sliding of the electric sliding seat 52 on the top of the guide rail assembly 51. During the cutting process, the cutting is carried out along the X-axis direction by continuously moving the electric sliding seat 52, and different depths can be cut by driving the fixed protection assembly 1 to ascend and descend by the hydraulic driving assembly B55, so as to ensure that the concrete member is cut off.

[0109] After cutting a cutting seam, the fixed protection assembly 1 is horizontally moved by the hydraulic driving assembly A53, so as to move the cutting blade 2 to another parallel cutting position, and finally the direction of the guide rail assembly 51 is adjusted for cutting in other directions.

[0110] Specifically, during the continuous cutting process, water is supplied to the inside of 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, and then input into the inside of one of the spraying pipes 33 through the communication hole A37 in the inside of the annular disc 35, and finally input into the inside of the other spraying pipe 33 through the U-shaped communication device 31, so that the two spraying pipes 33 can spray water sources to the outside of the cutting blade 2 at the same time through the nozzles 34 connected outside, so as to prevent the temperature of the cutting blade 2 from being too high during the cutting process.

[0111] At the same time, the water source mixes with the dust generated by the cutting blade 2, and the generated slurry is thrown to the inside of the moving protection assembly 4 under the action of the cutting blade 2. The moving protection assembly 4 can prevent the slurry from being thrown out of a large range to cause unnecessary pollution, and as the cutting depth of the cutting blade 2 changes, the motor B7 drives the driving gear 71 to rotate, the driving gear 71 drives the driven gear 312 to rotate, and then the annular disc 35 rotates, the annular disc 35 drives the support plate 32 to rotate inside the fixed protection assembly 1, and then the bottom of the arc-shaped shield 41 gradually moves upward, realizing effective shielding of the slurry.

[0112] Specifically, the moving protection assembly 4 is driven by the spraying assembly 3 to slide inside the fixed protection assembly 1, so that the bottom of the moving protection assembly 4 can move upward with the cutting depth of the cutting blade 2, so that the cutting opening generated during the cutting process of the cutting blade 2 always maintains a certain distance from the moving protection assembly 4, realizing effective shielding of the slurry and improving the protection effect; and the moving protection assembly 4 can be driven by the spraying assembly 3 to slide inside the fixed protection assembly 1, so that the moving protection assembly 4 can clean the inner wall of the fixed protection assembly 1 during the sliding process, preventing the slurry particles from accumulating and caking on the inside of the fixed protection assembly 1, and causing inconvenience for later cleaning work.

[0113] In addition, when the fixed protection assembly 1 and the moving protection assembly 4 in the concrete structure cutting device are cleaned, the pin 15 at the top of the arc-shaped limiting plate 58 of the fixed protection assembly 1 is pulled out, so that the pin 15 releases the locking of the fixed protection assembly 1. At this time, the moving protection assembly 4 on one side of the fixed protection assembly 1 deflects, and then drives the whole fixed protection assembly 1 to rotate, so as to adjust the opening of the fixed protection assembly 1 to an upward state.

[0114] Then, the spraying assembly 3 sprays water outside the cutting blade 2, and the water flow flows downward along the outside of the cutting blade 2 into the inside of the fixed protection assembly 1, and the fixed protection assembly 1 acts as a water container; the motor B7 outside the side plate B13 drives the spraying assembly 3 to rotate, so that the spraying assembly 3 drives the moving protection assembly 4 to slide inside the fixed protection assembly 1. During the sliding process, the friction plate 43 outside the arc-shaped shield 41 is tightly attached to the inner wall of the fixed protection assembly 1 under the action of the elastic sheet 42, and is elastically compressed, so that the slurry particles on the inner wall of the fixed protection assembly 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 by a certain angle, it gradually approaches the cleaning assembly 6, and finally the friction block 61 is elastically compressed inside the arc-shaped shield 41 under the action of the spring 62, so that the arc-shaped shield 41 cleans the inside of itself during the rotation process, preventing the slurry inside the arc-shaped shield 41 from accumulating and caking.

[0115] When the arc-shaped cover 41 drives the friction plate 43 to rotate repeatedly for a certain period, the motor A22 drives the driving shaft 23 to rotate, so that the driving shaft 23 drives the cutting blade 2 to rotate in the opposite direction of 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 assembly 1 to rotate outside the shell 57 through the connecting block 19.

[0116] When the slope B16 on one side of the fixed protection assembly 1 approaches the bottom of the plug 15, the slope B16 first approaches the bottom of the slope A151. Under the extrusion of the fixed protection assembly 1, the plug 15 is lifted upward. When the fixed protection assembly 1 drives the plug hole A14 to be located directly below the plug 15, the plug 15 is automatically inserted into the plug hole A14 under the action of its own gravity to lock the fixed protection assembly 1, so as to reset the fixed protection assembly 1 after cleaning. During the rotation and resetting of the fixed protection assembly 1, the wastewater generated by cleaning in the fixed protection assembly 1 can be automatically discharged, and the spraying assembly 3 can be continuously driven to reciprocate by the motor B7, so that the spraying assembly 3 can continuously spray water to the inside of the fixed protection assembly 1 and the outside of the cutting blade 2 during the resetting of the fixed protection assembly 1, so as to automatically wash the fixed protection assembly 1 and the cutting blade 2 during the resetting of the fixed protection assembly 1, so as to clean the silt and impurities generated during cleaning.

[0117] It is worth noting that the above cleaning method has the following advantages:

[0118] Advantage one: when cleaning the inside of the fixed protection assembly 1, only the plug 15 needs to be pulled out to make the fixed protection assembly 1 automatically flip by relying on the gravity of the moving protection assembly 4, so that the opening of the fixed protection assembly 1 faces upward as a water container, thereby ensuring the cleaning effect.

[0119] Advantage two: after the fixed protection assembly 1 is cleaned, the driving shaft 23 is driven to rotate in the opposite direction (relative to the rotating direction of the cutting blade 2) by the motor A22, so that the fixed protection assembly 1 is automatically reset by the connecting block 19 provided on the outer ring of the one-way bearing 24, which is more convenient to use.

[0120] Advantage three: in order to ensure the stability of the fixed protection assembly 1 after resetting, a slope B16 is arranged on one side of the fixed protection assembly 1. When the slope B16 on one side of the fixed protection assembly 1 approaches the plug 15, the slope B16 first approaches the bottom of the slope A151. Finally, under the interaction of the slope B16 and the slope A151, the plug 15 is lifted upward. When the fixed protection assembly 1 drives the plug hole A14 to be located directly below the plug 15, the plug 15 is automatically inserted into the plug hole A14 under the action of its own gravity to lock the fixed protection assembly 1, which further improves the convenience of use.

[0121] The fourth advantage is that when the inner side of the fixed protection assembly 1 is cleaned, the movable protection assembly 4 is driven by the spraying assembly 3 to slide on the inner side of the fixed protection assembly 1, and the friction plate 43 elastically arranged on the outer side of the arc-shaped cover 41 can clean the inner side of the fixed protection assembly 1, and during the cutting process of the cutting blade 2, the movable protection assembly 4 effectively shields the mud under the driving of the spraying assembly 3, and then the spraying assembly 3 can be used in different working conditions by changing the movement state, thereby reducing the cleaning cost and improving the cleaning efficiency.

[0122] The fifth advantage is that when the fixed protection assembly 1 is reset under the driving of the motor A22, the opening of the fixed protection assembly 1 is gradually tilted to automatically clean the silt and water generated during the cleaning, thereby further improving the cleaning efficiency.

[0123] The sixth advantage is that during the reset process of the fixed protection assembly 1, the spraying assembly 3 is driven to reciprocate by the motor B7, so that the spraying assembly 3 always sprays water to the inner side of the fixed protection assembly 1 and the outer side of the cutting blade 2 during the tilting process of the fixed protection assembly 1, so as to wash and remove the residual silt and impurities on the surface, and make the cleaning of the equipment more sufficient.

[0124] The seventh advantage is that during the movement of the movable protection assembly 4 driven by the spraying assembly 3, the arc-shaped cover 41 automatically cooperates with the cleaning assembly 6 on the inner side of the fixed protection assembly 1, so that the arc-shaped cover 41 can be cleaned while cleaning the inner side of the fixed protection assembly 1, and the silt accumulated on the inner side of the arc-shaped cover 41 is prevented from affecting the subsequent use.

[0125] In actual application, the pin 15 needs to be kept in a lubricated state between the pin hole A14 and the pin hole B59. In order to ensure the stability of the sliding reset of the pin 15, lubricating oil needs to be added to the inside of the pin hole B59 and the pin hole A14 before each cleaning, and in order to ensure that the inclined surface A151 at the bottom of the pin 15 faces the inclined surface B16, the pin hole B59 at the top of the arc-shaped limiting plate 58 is slidably arranged, so that the pin 15 can only slide vertically along the axial direction.

[0126] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not change the essence of the corresponding technical solutions out of the protection scope of the technical solutions of the embodiments of the present application.
