Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and specifically to a spraying device for traffic road signs. Background Art

[0002] Traffic road signs refer to signs on the road surface that use lines, arrows, words, raised road signs, and contour signs, etc., to convey traffic information such as guidance, restrictions, and warnings to traffic participants. Traffic road signs generally use manual or spraying devices to spray paint on the road surface to form road signs. When the existing spraying devices are used for road sign spraying, the marked positions need to be cleaned first to reduce the influence of sundries, etc. on spraying and improve the spraying quality. The existing spraying devices are not convenient for pre-cleaning the spraying positions, and additional cleaning work may be required manually or by mechanical equipment, which is inconvenient to use. Moreover, it is not convenient to evenly smear the signs after spraying, and the clarity of the paint signs may not be sufficient, resulting in the trouble of repeated spraying many times.

[0003] For example, a traffic road sign spraying device with the publication number CN213825466U includes rolling wheels, a road sign template, a handle, a slide rail, a painting device, etc.; rolling wheels are symmetrically arranged on the front and rear sides of the bottom of the road sign template, a handle is arranged on the rear side of the top of the road sign template, slide rails are arranged on the left and right sides of the top of the road sign template, and a painting device is arranged on the slide rails. The slide rails cooperate with the painting device. By turning on the water pump, the paint in the paint tank is sprayed out from the bottom of the protective cover along the painting pipe, and the sprayed paint falls onto the road surface through the road sign template. At the same time, the slide bar or the protective cover is moved, so that different road sign templates are printed on the road, achieving the effect of rapid spraying. However, the device is not convenient for pre-cleaning the marked positions, so sundries on the road surface will affect the spraying, reducing the spraying quality. Moreover, it is not convenient to evenly smear the signs after spraying, and the clarity of the paint signs may not be sufficient, so repeated spraying is required, and there are certain defects.

[0004] Therefore, a spraying device for traffic road signs is proposed to solve the above-mentioned problems. Summary of the Invention

[0028] Compared with the prior art, the beneficial effects of the present invention are:

[0029] 1. There is a spraying component and a cleaning component. When spraying work is carried out, the operator first pushes the push rod, and the push rod drives the cross plate to move towards the marking position. Then start the driving motor to work. The driving motor drives the screw rod part to rotate. The limiting block slides inside the limiting groove to limit the linear motor and the adjusting sleeve, so as to realize that the adjusting sleeve drives the linear motor to move horizontally. At this time, spraying work is not carried out. The screw rod part also drives the fixed disk to rotate, and the fixed disk drives the eccentric rod to rotate. The fixed cylinder limits the cross rod, and the sliding groove limits the bottom rod and the vertical rod, so that the fixed frame and the bottom rod only move horizontally and longitudinally. The rotation of the eccentric rod drives the fixed frame to move longitudinally back and forth, so that the bottom rod and the lower plate move longitudinally back and forth. The lower plate drives the adjusting rod and the cleaning plate to move back and forth. The adjusting rod also drives the upper plate and the contact block to move back and forth.

The spring assists the reset of the cleaning plate, so that the trajectory of the cleaning plate is inclined downward, which is convenient for the cleaning brush at the bottom of the cleaning plate to scrape and clean the ground obliquely downward. And when the screw rod part rotates one circle, the cleaning plate completes a movement and reset, which is convenient for the device to perform pre-cleaning treatment when moving to the marking position, reducing the influence of road dirt. During subsequent spraying, keep the template part above the marking position, start the linear motor, adjust the longitudinal position of the installation strip, so that the paint spraying head is located on one side of the printing groove of the template part. Then start the driving motor and the pressure pump to work. The driving motor drives the adjusting sleeve and the linear motor to move longitudinally. The pressure pump pumps the material through the paint tank, and transports the paint inside the paint tank to the installation strip through the discharge pipe and the telescopic hose. The paint is then sprayed out through the paint spraying head, and the shape is limited by the printing groove on the template part. Square grooves are provided at the bottom of the installation box and the middle of the cross plate for spraying to give way, solving the problem that the device is not convenient for pre-cleaning treatment of the marking position, so that road debris and the like will affect the marking and spraying, and reducing the spraying quality;

[0030] 2. There is a spraying component. After the spraying is completed, the operator turns off the driving motor and the pressure pump, pushes the push rod to drive the cross plate to move. The cross plate drives the mounting seat and the bolt part to move. The bolt part drives the rotating rod and the connecting block to move. The connecting block drives the vertical plate to move. The vertical plate drives the pushing flat plate to scrape and smear the sprayed mark to keep the thickness of the sprayed mark qualified. The operator turns the rotating rods on both sides, and the rotating rods drive the bolt part to rotate, so as to facilitate screwing the bolt part into or out of the mounting seat, thereby adjusting the height of the mounting ring. The mounting ring drives the height adjustment of the pushing flat plate, so as to adapt to the thickness requirements of different sprayed marks and is more flexible to use.

[0053] A cleaning component 7 is arranged on the outer side of the installation box 3. The cleaning component 7 includes a fixed disk 71 and an eccentric rod 72. The fixed disk 71 is fixedly connected to the end of the lead screw part 62 far from the drive motor 61. A fixed frame 73 is sleeved on the outer side of the eccentric rod 72. A bottom rod 74 is fixedly connected to the bottom of the fixed frame 73. A cross bar 75 is fixedly connected to the middle of the outer side of the bottom rod 74. A fixed cylinder 76 is fixedly connected to the side of the installation box 3 close to the fixed frame 73. The cross bar 75 is slidably connected to the fixed cylinder 76.

[0054] The fixed disk 71 is located outside the installation box 3. The eccentric rod 72 is located on the side of the fixed disk 71 far from the lead screw part 62. The eccentric rod 72 is eccentrically arranged. A limiting piece is fixedly connected to the end of the eccentric rod 72 far from the fixed disk 71. The inner width dimension of the fixed frame 73 is the same as the diameter dimension of the eccentric rod 72.

[0055] Sliding grooves 78 are symmetrically formed at the top of the cross plate 1. The bottom rod 74 is slidably connected to one of the sliding grooves 78. A vertical rod 77 is fixedly connected to the side of the cross bar 75 far from the bottom rod 74. The vertical rod 77 is slidably connected to the other sliding groove 78.

A contact block 715 is fixedly connected to the top of the upper plate 713. The contact block 715 abuts against the inclined surface of the trapezoidal block 714.

[0056] There are no less than two adjusting rods 710. The spring 712 is slidably connected to the adjusting rod 710. The two ends of the spring 712 are respectively fixedly connected to the cleaning plate 711 and the lower plate 79. A cleaning brush is fixedly connected to the bottom of the cleaning plate 711.

[0057] Example 1: As Figures 1-10 As shown in, when spraying work is carried out, the operator first pushes the push rod 5. The push rod 5 drives the cross plate 1 to move to the marked position. The drive motor 61 is started to work. The drive motor 61 drives the lead screw part 62 to rotate. The limit block 65 slides inside the limit groove 66 to limit the linear motor 64 and the adjusting sleeve 63, so as to realize that the adjusting sleeve 63 drives the linear motor 64 to move horizontally. At this time, spraying work is not carried out.

[0058] The lead screw part 62 drives the fixed disk 71 to rotate simultaneously. The fixed disk 71 drives the eccentric rod 72 to rotate. The fixed cylinder 76 limits the movement of the cross bar 75, and the sliding groove 78 limits the movement of the bottom rod 74 and the vertical rod 77, so that the fixed frame 73 and the bottom rod 74 only move horizontally and longitudinally. The rotation of the eccentric rod 72 drives the fixed frame 73 to move longitudinally in a reciprocating manner, so that the bottom rod 74 and the lower plate 79 move longitudinally in a reciprocating manner. The lower plate 79 drives the adjusting rod 710 and the cleaning plate 711 to move reciprocally. The adjusting rod 710 simultaneously drives the upper plate 713 and the contact block 715 to move reciprocally. The contact block 715 is squeezed by the trapezoidal block 714, so that while the contact block 715 drives the adjusting rod 710 and the cleaning plate 711 to move, it also moves downward. The spring 712 assists the reset of the cleaning plate 711, so that the trajectory of the cleaning plate 711 is inclined downward, facilitating the cleaning brush at the bottom of the cleaning plate 711 to scrape and clean the ground obliquely downward. And when the lead screw part 62 rotates one circle, the cleaning plate 711 completes one movement and reset, facilitating the pre-cleaning treatment when the device moves to the marked position and reducing the influence of road surface dirt.

[0059] During subsequent spraying, keep the template part 10 above the marked position. Start the linear motor 64 and adjust the longitudinal position of the mounting strip 67 so that the paint spraying head 68 is located on one side of the printing groove of the template part 10. Then start the driving motor 61 and the pressure pump 9. The driving motor 61 drives the adjusting sleeve 63 and the linear motor 64 to move longitudinally. The pressure pump 9 pumps materials through the paint tank 8, and the paint inside the paint tank 8 is transported to the mounting strip 67 through the discharge pipe 69 and the telescopic hose 610. The paint is then sprayed out through the paint spraying head 68 and is shaped by the printing groove on the template part 10. Square grooves are provided at the bottom of the mounting box 3 and the middle of the cross plate 1 for spraying to make way, solving the problem that the device is not convenient for pre-cleaning the marked position, which causes the influence of road surface sundries on the marking and spraying and reduces the spraying quality.

[0060] The spraying component 6 further includes a vertical plate 612 and symmetrically arranged mounting seats 611. The top of the mounting seat 611 is fixedly connected to the other side of the bottom of the cross plate 1. One side of the vertical plate 612 away from the mounting seat 611 is fixedly connected with an outer cover body 613. A push flat plate 614 is fixedly connected to the lower part inside the outer cover body 613. One side of the top of the push flat plate 614 is hook-shaped. Symmetrically fixed connection blocks 615 are arranged on one side of the vertical plate 612 close to the mounting seat 611.

[0061] One side of the connection block 615 away from the vertical plate 612 is fixedly connected with a mounting ring 616. A rotating rod 617 is rotatably mounted inside the mounting ring 616 through a bearing. A retaining piece 618 is fixedly connected to the top of the rotating rod 617. A bolt part 619 is fixedly connected to the top of the retaining piece 618. The bolt part 619 is threadedly connected to the mounting seat 611. The positions of the two connection blocks 615 correspond to the two mounting seats 611 one by one.

[0062] Embodiment 2: AsFigures 11-13 As shown, after the spraying is completed, the operator turns off the drive motor 61 and the pressure pump 9, pushes the push rod 5 to drive the cross plate 1 to move, the cross plate 1 drives the mounting seat 611 and the bolt part 619 to move, the bolt part 619 drives the rotating rod 617 and the connecting block 615 to move, the connecting block 615 drives the vertical plate 612 to move, and the vertical plate 612 drives the pushing and flattening plate 614 to scrape and smooth the printed mark, so as to keep the thickness of the printed mark qualified. The operator turns the rotating rods 617 on both sides, and the rotating rods 617 drive the bolt part 619 to rotate, so as to facilitate screwing the bolt part 619 into or out of the mounting seat 611, thereby adjusting the height of the mounting ring 616. The mounting ring 616 drives the height adjustment of the pushing and flattening plate 614, so as to adapt to the thickness requirements of different printed marks and be more flexible to use.

[0063] Working principle: When using this device, first, as Figures 1-13 shown, the operator first pushes the push rod 5, and the push rod 5 drives the cross plate 1 to move towards the marking position. The drive motor 61 is started to work. At this time, spraying work is not carried out. The lead screw part 62 drives the fixed disk 71 to rotate at the same time, and the fixed disk 71 drives the eccentric rod 72 to rotate, so that the fixed frame 73 and the bottom rod 74 only move horizontally and longitudinally. The lower plate 79 drives the adjusting rod 710 and the cleaning plate 711 to move back and forth. The contact block 715 is squeezed by the trapezoidal block 714, so that the trajectory of the cleaning plate 711 is inclined downward, so as to facilitate the cleaning brush at the bottom of the cleaning plate 711 to scrape and clean obliquely downward on the ground, reducing the influence of road dirt. During subsequent printing, keep the template part 10 above the marking position, start the linear motor 64, adjust the longitudinal position of the mounting strip 67, and then start the drive motor 61 and the pressure pump 9 to work. The drive motor 61 drives the adjusting sleeve 63 and the linear motor 64 to move longitudinally. The pressure pump 9 pumps materials through the paint tank 8, and the paint inside the paint tank 8 is transported to the mounting strip 67 through the discharge pipe 69 and the telescopic hose 610. The paint is then sprayed out through the paint spraying head 68, so as to realize the printing of the mark. After the spraying is completed, the operator turns off the drive motor 61 and the pressure pump 9, pushes the push rod 5 to drive the cross plate 1 to move, and the pushing and flattening plate 614 scrapes and smooths the printed mark, so as to keep the thickness of the printed mark qualified. The operator turns the rotating rods 617 on both sides to adjust the height of the mounting ring 616. The mounting ring 616 drives the height adjustment of the pushing and flattening plate 614, so as to adapt to the thickness requirements of different printed marks and be more flexible to use.
