Description

Technical Field

[0001] The present invention relates to the technical field of line marking devices, and in particular to a line marking device for foundation construction. Background Art

[0002] Before constructing a building on the foundation, workers need to draw lines on the leveled foundation. The line drawing work provides an accurate benchmark for subsequent construction and ensures the location, size and other requirements of the building. When drawing lines, it is also necessary to avoid drawing the lines on debris (such as leaves). These debris will affect the adhesion of the lines, making the drawn lines easy to peel, warp or fall off, resulting in poor line drawing results.

[0003] For example, the patent with publication number CN217556662U discloses a landscape construction marking device. Although this landscape construction marking device, when the road surface is undulating, under the elastic force of the buffer spring, the buffer roller always keeps close to the ground, so that the bottom end of the marking head maintains an equal distance from the ground, preventing the bottom end of the marking head from touching the ground; the V-shaped protective frame is used to protect the marking head, preventing stones and debris on the road surface from touching the marking head, thereby improving the protection of the marking head; the output end of the micro pump is connected to one end of the connecting hose through a flow valve, so that the flow rate of the paint outflow is stable, thereby ensuring the uniform thickness of the drawn straight line and improving the marking accuracy; however, when this landscape construction marking device is actually used, the cart moves forward and cannot clear the debris in front of the cart, so that the marking head on the cart easily draws paint on the debris, thereby affecting the paint drawing effect on the foundation.

DETAILED DESCRIPTION

[0028] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0029] The following is combined with Figures 1-10 This embodiment is described in further detail.

[0030] like Figure 1-10 As shown, a marking device for foundation construction in this embodiment includes a base plate 100 and a plurality of universal wheels 101 provided on the lower end surface of the base plate 100. A material box 110 is provided on the upper end surface of the base plate 100. A material cavity 401 opening upward and used for placing paint is defined in the material box 110. A marking head 300 is provided on the lower end surface of the material box 110 and passes through the base plate 100. A detachable cover 111 is also provided on the upper end surface of the material box 110 for closing the material cavity 401. A first cleaning assembly is provided on the bottom plate 100, and the first cleaning assembly is used to clean the dust below the bottom plate 100; The lower end surface of the bottom plate 100 is further provided with a second cleaning assembly, and the first cleaning assembly is used to drive the second cleaning assembly to clean the debris below the bottom plate 100; A turning assembly is also provided in the material chamber 401, and the second cleaning assembly is used to drive the turning assembly to continuously turn the paint in the material chamber 401; A stirring assembly is also provided in the material chamber 401, and the turning assembly is used to drive the stirring assembly to continuously stir the coating.

[0031] In this embodiment, the paint for marking is poured into the material chamber 401, and the cover plate 111 is installed on the material box 110. At this time, the worker pushes the base plate 100 onto the leveled foundation. When the base plate 100 moves on the foundation, the paint in the material chamber 401 can flow out of the material box 110 through the line drawing head 300 and adhere to the foundation, thereby achieving the line drawing operation on the foundation; The foundation is prone to a lot of dust. When paint is directly drawn on the dust, the drawn line is not firm and is easily detached. To avoid this, when the line drawing head 300 moves through the base plate 100 to draw a line, the first cleaning component on the base plate 100 cleans the dust under the base plate 100 to both sides of the line drawing head 300, so that the line drawing head 300 can draw the paint on the foundation, thereby improving the line drawing effect of the line drawing head 300 on the foundation. When the first cleaning component is working, the first cleaning component also drives the second cleaning component, which cleans the debris under the base plate 100 to both sides of the marking head 300. Compared with the existing device, this foundation construction marking device can prevent the marking head 300 from marking paint on the debris during actual use, resulting in poor marking effect of the marking head 300 on the foundation. Among them, when the second cleaning component is cleaning the debris, the second cleaning component will also drive the turning component to turn over the paint in the material chamber 401, thereby preventing the paint in the material chamber 401 from settling and stratifying. When the turning component turns over the paint in the material chamber 401, the turning component will also drive the stirring component to work, and the stirring component will continuously stir the paint in the material chamber 401, thereby further reducing the paint from settling and stratifying in the material chamber 401. Among them, a positioning plate 1000 is fixedly installed on the lower end surface of the cover plate 111, which is opposite to and extends into the material cavity 401, and a bolt 112 is provided on the opposite side wall of the material box 110 for positioning the positioning plate 1000. When the cover plate 111 is placed on the material box 110, the positioning plate 1000 on the cover plate 111 will be located in the material cavity 401. At this time, by rotating the bolt 112 and inserting one end of the bolt 112 into the corresponding positioning plate 1000, the cover plate 111 is installed on the material box 110. At this time, the cover plate 111 closes the opening of the material cavity 401, which can prevent dust outside the material box 110 from falling into the material cavity 401 and causing pollution to the paint in the material cavity 401. Among them, universal wheels 101 are fixedly installed at the four corners of the base plate 100, so that the base plate 100 can be pushed and moved by the universal wheels 101. In order to facilitate the staff to push the base plate 100, a pushing frame 102 is fixedly installed at one end of the base plate 100, and the pushing frame 102 facilitates the staff to push the base plate 100 to move; During actual use, the material box 110 is fixedly mounted on the base plate 100, and the line drawing head 300 is fixedly mounted on the material box 110. An electromagnetic valve is installed in the line drawing head 300. By opening the electromagnetic valve, the paint in the material chamber 401 can flow out through the line drawing head 300 to draw lines on the foundation. When the electromagnetic valve is closed, the line drawing head 300 stops drawing lines on the foundation.

[0032] like Figure 1-7 As shown, in this embodiment, a fixing shell 120 is provided on the upper end surface of the base plate 100, a fixing cavity is provided in the fixing shell 120, and a groove is provided on the lower end surface of the base plate 100; The first cleaning component includes a motor 121 arranged on a fixed shell 120. The output shaft of the motor 121 passes through the fixed cavity and extends into a groove. A blowing fan 500 connected to the output shaft of the motor 121 is provided in the groove. The motor 121 drives the blowing fan 500 to blow air to clean the dust under the base plate 100.

[0033] In this embodiment, by setting the fixed shell 120, the fixed cavity, the groove and the blowing fan 500, the fixed shell 120 is fixedly installed on the base plate 100, the blowing fan 500 is fixedly installed in the groove, and the motor 121 is fixedly installed on the fixed shell 120. When the motor 121 drives the blowing fan 500 to blow the air, the blowing fan 500 blows air to the foundation under the base plate 100, thereby blowing the dust on the foundation to both sides of the drawing head 300.

[0034] like Figure 1-6 As shown, in this embodiment, a mounting shell 510 is provided on the lower end surface of the base plate 100, and a mounting cavity 601 is defined in the mounting shell 510. Mounting rods 511 are provided in the mounting cavity 601, and one end of the mounting rods 511 extends out of the mounting shell 510. Springs 610 are sleeved on the mounting rods 511 in the mounting cavity 601. The second cleaning component includes a slidable cleaning plate 520 provided on the lower end surface of the base plate 100, a brush 521 is provided on the lower end surface of the cleaning plate 520, and a side wall of the cleaning plate 520 is provided with a through portion 620 corresponding to and for the corresponding mounting rod 511 to pass through. One end of the through portion 620 extends into the mounting cavity 601 and is provided. The through portions 620 located in the mounting cavity 601 are all provided with a pushing ring 621 for being pushed by the corresponding spring 610. A driving member is provided in the fixed cavity, and the driving member is used to drive the cleaning plate 520 to move toward the mounting shell 510, so that the cleaning plate 520 drives the brush 521 to clean up debris.

[0035] In this embodiment, by setting the mounting shell 510, the mounting cavity 601, the mounting rod 511, the spring 610, the cleaning plate 520, the brush 521, the through portion 620, the push ring 621 and the driving member, the mounting shell 510 is fixedly mounted on the bottom plate 100, the mounting rod 511 is fixedly mounted on the side wall of the mounting cavity 601, the brush 521 and the through portion 620 are fixedly mounted on the cleaning plate 520, and the push ring 621 is fixedly mounted on the through portion 620. When the driving member drives the cleaning plate 520 to move the mounting shell 510, the cleaning plate 520 will drive the through portion 620 and the push ring 621 to move. 21 moves, at this time, the pushing ring 621 compresses the spring 610. When the driving member releases the driving of the cleaning plate 520, the spring 610 is decompressed, so that the spring 610 pushes the pushing ring 621 to move, so that the pushing ring 621 can drive the cleaning plate 520 away from the mounting shell 510 through the through portion 620. In this reciprocating manner, the cleaning plate 520 drives the brush 521 to reciprocate under the bottom plate 100. The reciprocating movement of the brush 521 cleans the impurities under the bottom plate 100 to both sides of the line drawing head 300, thereby preventing the line drawing head 300 from drawing on the impurities; Among them, a mounting plate 540 is fixedly mounted on the lower end surface of the base plate 100, and the protruding ends of the mounting rods 511 are fixedly mounted on the mounting plate 540, so that both ends of the mounting rods 511 can be mounted; During actual use, a shielding plate 522 is fixedly installed on the side wall of the cleaning plate 520 facing the mounting shell 510. The side wall of the shielding plate 522 slides and fits with the side wall of the mounting shell 510, so that the gap between the cleaning plate 520 and the mounting shell 510 will not be exposed, thereby preventing some debris from being stuck in the gap between the cleaning plate 520 and the mounting shell 510, affecting actual use.

[0036] like Figure 1-8 As shown, in this embodiment, a first gear 800 is sleeved on the output shaft of the motor 121 located in the fixed cavity; The driving member includes a rotating rod 200 arranged in the fixed cavity and with the lower end passing through the bottom plate 100.

When the motor 121 drives the first gear 800 to rotate, the first gear 800 can drive the rotating rod 200 to rotate through the second gear 810, and the rotation of the rotating rod 200 drives the rotating plate 530 to rotate. When the rotating plate 530 rotates, the two ends of the rotating plate 530 will push the cleaning plate 520 to move the mounting shell 510 at intervals, so that the cleaning plate 520 can clean the debris under the base plate 100.

The hinge block 921 is rotatably mounted on the lifting base 900 through a bearing, thereby realizing the hinged installation of the hinge rod 920 between the protruding rod 910 and the lifting base 900; Among them, opposite horizontal plates 113 are fixedly installed on the side walls of the material box 110, and the upper ends of the two vertical rods 122 are fixedly installed on the corresponding horizontal plates 113 to fix the two ends of the vertical rods 122; In actual use, a second protective shell 150 is fixedly installed on the side wall of the material box 110, and the first sprocket 210, the round rod 310, the second sprocket 311, the chain 211 and the third gear 220 are all located in the second protective shell 150, so that the first sprocket 210, the round rod 310, the second sprocket 311 and the chain 211 can be protected by the second protective shell 150.

[0042] like Figure 1-10 As shown, in this embodiment, the stirring assembly includes a rotatable vertical rod 430 arranged in the material chamber 401, and multiple stirring rods 431 are provided on the side wall of the vertical rod 430. The vertical rod 430 drives the stirring rod 431 to rotate, so that the stirring rod 431 can continuously stir the paint in the material chamber 401.

[0043] In this embodiment, the vertical rod 430 and the stirring rod 431 are arranged so that the stirring rod 431 is fixedly mounted on the vertical rod 430. When the vertical rod 430 rotates, the stirring rod 431 rotates along the circumference of the vertical rod 430, thereby stirring the coating in the material chamber 401. In actual use, a sleeve 1100 is fixedly mounted on the lower end surface of the cover plate 111. When the cover plate 111 is mounted on the material box 110, the upper end of the vertical rod 430 is inserted into the sleeve 1100. The sleeve 1100 limits the upper end of the vertical rod 430, making the rotation of the vertical rod 430 more stable. like Figure 1-4 As shown, in this embodiment, a fourth gear 440 is sleeved on the vertical rod 430, and the two flip plates 410 are each provided with a second rack 411 meshing with the fourth gear 440, so that the flip plates 410 move and drive the vertical rod 430 to rotate.

[0044] In this embodiment, by disposing the fourth gear 440 and the second rack 411, the fourth gear 440 is fixedly mounted on the vertical rod 430, and the second rack 411 is fixedly mounted on the corresponding flip plate 410. When the two flip plates 410 move relative to each other, the two flip plates 410 can drive the fourth gear 440 to rotate through the second rack 411, so that the fourth gear 440 drives the vertical rod 430 to rotate back and forth, so that the stirring rod 431 on the vertical rod 430 stirs the paint in the material chamber 401. In actual use, when the two flip plates 410 approach each other, the vertical rod 430 drives the stirring rod 431 to rotate, and makes the stirring rod 431 parallel to the flip plates 410, thereby avoiding interference between the flip plates 410 and the stirring rod 431.

[0045] like Figure 1-5 As shown, in this embodiment, a protective block 550 is provided on the lower end surface of the base plate 100, and a downward-opening protective groove is provided in the protective block 550. The drawing head 300 is located in the protective groove. An electric push rod 560 is also provided on the lower end surface of the base plate 100, and a protective plate 561 is provided on the output shaft. The electric push rod 560 drives the protective plate 561 to close the protective groove, thereby protecting the drawing head 300.

[0046] In this embodiment, the protection block 550, the protection groove, the electric push rod 560 and the protection plate 561 are arranged so that the protection block 550 is fixedly mounted on the lower end surface of the base plate 100, the cross section of the protection plate 561 is L-shaped, and the protection plate 561 is fixedly mounted on the electric push rod 560. When the line drawing head 300 is not drawing, the electric push rod 560 drives the protection plate 561 to move and close the protection groove. The line drawing head 300 is protected in the protection groove, thereby preventing the line drawing head 300 from colliding with hard objects and causing damage to the line drawing head 300. When the electric push rod 560 drives the protection plate 561 to move and releases the closure of the protection groove, the line drawing head 300 can now draw. The lower end surface of the base plate 100 is fixedly mounted with opposite mounting seats 562 , and the electric push rod 560 is fixedly mounted on the two mounting seats 562 ; In actual use, a speed sensor (not shown in the figure) is installed on the driving rod 230, and a controller (not shown in the figure) is also installed on the base plate 100. The speed sensor is electrically connected to the controller, and the controller is electrically connected to the electric push rod 560. When the speed sensor detects that the driving rod 230 is rotating, the speed sensor sends a signal to the controller, and the controller drives the electric push rod 560. The electric push rod 560 drives the protective plate 561 to remove the obstruction of the drawing head 300. When the driving rod 230 stops rotating, the speed sensor sends a signal to the controller, and the controller drives the electric push rod 560. The electric push rod 560 drives the protective plate 561 to close the protective groove.

[0047] When this embodiment is actually used, first, paint is poured into the material chamber 401, and then, the cover plate 111 is installed on the material box 110 by the bolt 112. At this time, the staff can push the bottom plate 100 to the leveled foundation through the cooperation of the pushing frame 102 and the universal wheel 101. When the bottom plate 100 moves, the solenoid valve opens, so that the line drawing head 300 can draw the paint on the foundation to achieve the line drawing of the foundation. When the foundation is drawing, the motor 121 drives the air blowing fan 500 to rotate, and the dust under the bottom plate 100 is blown away to both sides of the line drawing head 300. At the same time, through the cooperation of the first gear 800 and the second gear 810, the rotating rod 200 drives the rotating plate 530 to rotate, and the rotating plate 530 drives the cleaning plate 520 to drive the brush 521 to move back and forth, cleaning the debris under the bottom plate 100 to both sides of the line drawing head 300, so that the line drawing head 300 can be cleaned. When the paint is drawn on the foundation, the paint line is drawn on the foundation. When the rotating rod 200 rotates, the rotating rod 200 cooperates with the first bevel gear 201 and the second bevel gear 231 to make the driving rod 230 rotate through the cooperation of the circular plate 130 and the hinged rod 920, so that the lifting plate 123 can drive the first rack 124 to rise and fall, and the first rack 124 drives the third gear 220 to rotate, that is, the chain 211 passed by the second sprocket 311 drives the first sprocket 210 to rotate, that is, the threaded rod 450 rotates, and the threaded rod 450 drives the two flip plates 410 to move closer to or away from each other, thereby turning the paint in the material chamber 401 to avoid sedimentation and stratification of the paint in the material chamber 401. The two flip plates 410 move and drive the fourth gear 440 on the vertical rod 430 to rotate through the second rack 411, that is, the vertical rod 430 drives the stirring rod 431 to rotate, thereby further reducing the sedimentation and stratification of the paint in the material chamber 401.

[0048] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
