Therefore, an automatic spraying and maintenance device for concrete pavement for bridge construction is proposed to solve the above-mentioned problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic spraying and maintenance device for concrete pavement used in bridge construction, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention is implemented through the following technical solutions: an automatic spraying maintenance device for concrete pavement used in bridge construction, comprising a bearing plate, the bottom of the bearing plate is equidistant and has a plurality of arc-shaped grooves, support columns are fixedly installed at the corners of the bottom of the bearing plate, a moving component is fixedly installed at the bottom of the support column, a water storage tank is arranged on the top of the bearing plate, and a water inlet component is arranged on the top of the water storage tank;

[0007] The anti-obstruction device includes an electric reciprocating rod, the bottom of which passes through and rotates on the top of the moving component, the outer wall of the electric reciprocating rod passes through and is threadedly connected with a fixed frame, a limit rod passes through and is slidably installed inside the right end of the fixed frame, a plurality of spray components are fixedly installed inside the fixed frame, a spiral water pipe is fixedly installed between the top of the spray component and the bottom of the water tank, the fixed frame has two U-shaped plates symmetrically and hingedly installed on the side away from the axis of the bearing plate, a filter plate is fixedly installed inside the U-shaped plate, a plurality of friction wheels are symmetrically and rotatably installed on the inner wall of the U-shaped plate, a plurality of the friction wheels are fixedly installed with round rods close to the side of the axis of the U-shaped plate, and a plurality of elastic retractable plates are equidistantly and fixedly installed on the outer wall of the round rod.

[0008] According to the above technical solution, the bottom of the limit rod is fixedly installed on the top of the moving component, some of the spray components are located directly below the water tank, and some of the spray components are equidistantly distributed inside the fixed frame. A torsion spring is arranged between the top of the two U-shaped plates and the fixed frame, and the telescopic ends of some of the elastic telescopic plates are all convex from the outer wall of the friction wheel. When the bearing plate is moved, the moving component is prompted to move synchronously through the support column, and the moving component starts to rotate by generating friction through contact with the bridge deck. The moving component converts the sliding friction into rolling friction, and the bearing plate drives the water tank to move synchronously. When the spray maintenance work starts, the electric reciprocating rod is started, and the electric reciprocating rod drives the threaded fixed frame to slide up and down along the outer wall of the limit rod when rotating forward and reversely. When the fixed frame slides up and down, it drives the spray component to move synchronously, and the spray component pulls the spiral water The tube extends and deforms synchronously, and at this time, the spraying water source is transported to the inside of the spray assembly through the water tank with the help of the spiral water pipe, and the maintenance water source is sprayed onto the bridge deck through the spray assembly; when the fixed frame moves up and down, it drives the U-shaped plate to move synchronously, and the bottom of the U-shaped plate is limited by the friction wheel, and the outer wall of the friction wheel is in contact with the bridge deck, so the hinge axis of the U-shaped plate starts to rotate and pushes the friction wheel to move along the bridge deck away from the axis of the load-bearing plate. When the fixed frame is reset, the U-shaped plate is pulled to reset, and the U-shaped plate drives the filter plate to move synchronously, and the friction wheel generates a rotational force through the friction between the bridge deck, and the friction wheel rotates along the inner wall of the U-shaped plate, driving the round rod to rotate, and the round rod drives the elastic telescopic plate to rotate, and the telescopic end of the elastic telescopic plate is convex to the friction wheel, so that the telescopic end of the elastic telescopic plate contacts the ground and contracts toward the inside of its own fixed end after being squeezed.

[0009] According to the above technical solution, the anti-overflow device includes a transmission plate, a dust collection assembly, a U-shaped square groove plate and a plurality of resonant thin sheets. The bottom of the transmission plate is hinged at the outer wall of the fixed frame, the top of the dust collection assembly is slidably installed on the bottom of the supporting plate, the top of the U-shaped square groove plate away from the axis of the supporting plate is fixedly installed on the bottom of the dust collection assembly, and both sides of the plurality of resonant thin sheets are fixedly installed inside the U-shaped square groove plate.

[0010] The U-shaped square groove plate is guided by its own curved surface and the curved surface of the curved groove is guided to the bottom of the U-shaped square groove plate so that the resonant thin sheets are equidistantly distributed inside the U-shaped square groove plate. When the fixed frame moves downward and resets, the transmission plate is driven to move synchronously. The top of the transmission plate is restricted by the dust suction component, which causes the hinge axis of the transmission plate to start rotating. At this time, the transmission plate pulls the dust suction component with the hinge axis as the axis to slide along the bottom of the bearing plate toward the fixed frame. The dust suction component drives the U-shaped square groove plate to move synchronously. During the sliding process, the curved surface at the top of the U-shaped square groove plate contacts the inner wall of the curved groove at the bottom of the bearing plate to generate a resistance force, thereby bending and deforming. When the U-shaped square groove plate is freed from the resistance through its own curved surface and the curved surface of the curved groove, the U-shaped square groove plate will swing back and forth to generate a vibration force when it is reset through its own toughness. At this time, the U-shaped square groove plate causes the resonant thin sheets inside itself to vibrate synchronously, thereby increasing the vibration frequency.

[0011] According to the above technical solution, the anti-overflow device also includes a number of vertical plates, support rods and guide plates. The tops of the several vertical plates are symmetrical and fixedly installed at the bottom edge of the dust collection assembly. Both ends of the support rods are fixedly installed on the side of the vertical plate close to the dust collection assembly. The top of the guide plate is hinged to the bottom of the supporting plate. The guide plate penetrates through the inside and is hinged to the outer wall of the support rod. The dust collection assembly drives the vertical plates to move synchronously, the vertical plates drive the support rods to move synchronously, and the support rods pull the guide plates to move synchronously. The pulling force causes the hinge shaft between the top of the guide plate and the bottom of the supporting plate to start rotating, and the guide plate moves in an arc trajectory with the hinge shaft as the axis toward the fixed frame.

[0012] According to the above technical scheme, the anti-residue device includes a circular frame, a friction plate, an elastic telescopic column and a trapezoidal plate, the bottom of the circular frame is hinged to the side of the guide plate close to the U-shaped plate through a torsion spring, the friction plate is slidably installed on the outer wall of the filter plate close to the U-shaped plate, the outer wall of the friction plate is hinged to the top of the circular frame, the top of the elastic telescopic column is fixedly installed at the bottom edge of the friction plate, the outer wall of the trapezoidal plate is fixedly installed inside the telescopic end of the elastic telescopic column, the trapezoidal plate is in contact with the outer wall of the filter plate close to the U-shaped plate, and the guide plate drives the circular frame to move synchronously when the arc trajectory moves, and the circular frame is limited by the friction plate to prompt its own hinge axis to start rotating, at this time the circular frame will push the friction plate to slide upward along the outer wall of the filter plate, the friction plate continuously rubs the surface of the filter plate during the sliding process, and at the same time the friction plate drives the elastic telescopic column to move synchronously, and the elastic telescopic column pulls the trapezoidal plate to slide synchronously along the outer wall of the filter plate, and when the trapezoidal plate scrapes the outer wall of the filter plate and is hindered by solidified dirt, the elastic telescopic column continuously extends under the pull of the friction plate and the spring inside itself is synchronously deformed to generate a resetting elastic force.

[0013] According to the above technical solution, the anti-residue device also includes a number of transmission wheels, a reciprocating screw, a protective shell and a sponge block. The several transmission wheels are symmetrically and rotatably installed on the inner wall of the fixed end of the elastic telescopic column. Both ends of the reciprocating screw are fixedly installed on the side of the transmission wheel close to the axis of the circular frame. The protective shell penetrates through and is movably installed on the outer wall of the reciprocating screw. The outer wall of the sponge block is fixedly installed inside the protective shell.

[0014] According to the above technical scheme, the outer wall of the transmission wheel contacts the outer wall of the filter plate, the top of the protective shell is slidably connected to the bottom of the friction plate, the sponge block contacts the outer wall of the filter plate away from the side of the circular frame, and the elastic telescopic column drives the transmission wheel to move synchronously when the telescopic end moves. The transmission wheel rubs synchronously along the surface of the filter plate and generates a rotational force. The transmission wheel drives the reciprocating screw to rotate. The reciprocating screw limits the built-in block of the protective shell through the reciprocating spiral groove on its own outer wall, so that the protective shell can slide and reset on the outer wall of the reciprocating screw along the bottom of the friction plate, and the protective shell drives the sponge block to wipe the surface of the filter plate.

[0015] The present invention provides an automatic spraying and maintenance device for concrete pavement used in bridge construction. It has the following beneficial effects:

[0016] (1) The present invention sets an anti-obstruction device, and cooperates with an electric reciprocating rod, a fixed frame, a limit rod, a spray assembly, a spiral water pipe, a U-shaped plate, a filter plate, a friction wheel, a round rod and an elastic telescopic plate. With the help of the spray assembly, the spray height is continuously changed, so as to more accurately control the direction and intensity of the water flow, thereby improving the dust reduction range and effect of the device during bridge construction; and with the help of the filter plate, the dust scraped by the elastic telescopic plate is shielded, and at the same time, the elastic telescopic plate rotates to scrape off the concrete dust on the bridge deck, thereby ensuring the cleanliness of the bridge deck sprayed by the spray assembly, preventing concrete dust from combining with the sprayed water source to form cement, and then affecting the flatness of the bridge after subsequent drying.

[0017] (2) The present invention sets an anti-overflow device, and cooperates with a fixed frame, a transmission plate, a dust collection component, a U-shaped square groove plate, a resonance sheet, a vertical plate, a support rod and a guide plate. The resonance sheet is used to extend the vibration time of the U-shaped square groove plate. At the same time, the transmission plate expands the activity range of the dust collection component. The dust collection component absorbs the raised concrete dust in time to improve the dust reduction effect, and reduces the adhesion of dust to the suction port of the dust collection component by means of vibration force, effectively preventing the powder from scattering everywhere and falling on the bridge surface for a second time to interfere with the maintenance and dust reduction work. At the same time, the guide plate continuously changes its inclination amplitude as the dust collection component moves, and effectively shields and guides the concrete dust sucked by the dust collection component, ensuring that the raised dust can be sucked into the dust collection component in time, further preventing the concrete dust from overflowing and preventing the staff from inhaling the concrete dust.

[0018] (3) The present invention increases the scraping force of the trapezoidal plate on the filter plate by setting an anti-residue device through the coordination of the guide plate, the circular frame, the friction plate, the elastic telescopic column, the trapezoidal plate, the transmission wheel, the reciprocating screw, the protective shell and the sponge block, so as to prevent the dirt from solidifying and corroding the surface of the filter plate and shortening its service life. When the guide plate is close to the filter plate, an angle is formed between the two, so that the dust or actual particles scraped off the surface of the filter plate are conveniently absorbed by the dust collection component in time, so as to prevent the dirt from scattering and adhering to or remaining on the surface of the filter plate, and prevent the dust from drifting into the spraying component after falling off. At the same time, the sponge block can effectively expand the wiping range of the filter plate surface, and the sponge block can timely absorb the water droplets attached to the filter plate surface due to the splashing of the maintenance water source, so as to ensure the dryness of the filter plate and prevent the viscosity of the concrete dust on the filter plate from increasing due to the increase of humidity, thereby increasing the adhesion amount and causing the filter plate to be eroded more.

[0032] The bottom of the limit rod 43 is fixedly installed on the top of the moving component 21, and a plurality of spray components 44 are located directly below the water tank 3. A plurality of spray components 44 are equidistantly distributed inside the fixed frame 42. A torsion spring is arranged between the top of the two U-shaped plates 46 and the fixed frame 42. The telescopic ends of a plurality of elastic retractable plates 410 are all protruding from the outer wall of the friction wheel 48. Through the above cooperation, the spray height is continuously changed with the help of the spray component 44, so as to more accurately control the direction and intensity of the water flow, and enhance the dust reduction range and effect of the device during bridge construction; through the above cooperation, the dust scraped by the elastic retractable plate 410 is shielded with the help of the filter plate 47, and at the same time, the elastic retractable plate 410 rotates to scrape off the concrete dust on the bridge deck, thereby ensuring the cleanliness of the bridge deck sprayed by the spray component 44, and preventing the concrete dust from combining with the sprayed water source to form cement, thereby affecting the flatness of the bridge after it dries up.

[0033] When in use, when the bearing plate 1 is moved, the supporting column 2 is used to cause the moving component 21 to move synchronously. The moving component 21 starts to rotate by generating friction through contact with the bridge deck. The moving component 21 converts sliding friction into rolling friction, and the bearing plate 1 drives the water tank 3 to move synchronously. When the spray maintenance work starts, the electric reciprocating rod 41 is started. When the electric reciprocating rod 41 is reversed, the threaded fixed frame 42 is driven to slide up and down along the outer wall of the limit rod 43. When the fixed frame 42 slides up and down, it drives the spray component 44 to move synchronously. The spray component 44 pulls the spiral water pipe 45 to extend and deform synchronously. At this time, the spray water source is transported to the inside of the spray component 44 through the water tank 3 with the help of the spiral water pipe 45, and the maintenance water source is sprayed onto the bridge deck through the spray component 44. Through the above cooperation, the spray height is continuously changed with the help of the spray component 44, so as to more accurately control the direction and intensity of the water flow, and enhance the dust reduction range and effect of the device during bridge construction; when the fixed frame 42 moves up and down, it drives the U-shaped plate 46 to move synchronously, and the bottom of the U-shaped plate 46 The U-shaped plate 46 is limited by the friction wheel 48, and the outer wall of the friction wheel 48 is in contact with the bridge deck, so the hinge axis of the U-shaped plate 46 starts to rotate and pushes the friction wheel 48 to move along the bridge surface in the direction away from the axis of the load-bearing plate 1.

[0034] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-overflow device 5;

[0035] The anti-overflow device 5 includes a transmission plate 51, a dust collection assembly 52, a U-shaped square groove plate 53 and a plurality of resonant thin sheets 54. The bottom of the transmission plate 51 is hinged to the outer wall of the fixed frame 42, the top of the dust collection assembly 52 is slidably installed on the bottom of the supporting plate 1, the top of the U-shaped square groove plate 53 away from the axis of the supporting plate 1 is fixedly installed on the bottom of the dust collection assembly 52, and both sides of the plurality of resonant thin sheets 54 are fixedly installed inside the U-shaped square groove plate 53.

[0036] The outer wall of the dust collection component 52 is hinged on the top of the transmission plate 51 close to the fixed frame 42. The top of the U-shaped square groove plate 53 contacts the arc groove at the bottom of the bearing plate 1. A number of resonance sheets 54 are equidistantly distributed inside the U-shaped square groove plate 53. Through the above coordination, the resonance sheets 54 are used to extend the vibration duration of the U-shaped square groove plate 53. At the same time, the transmission plate 51 expands the activity range of the dust collection component 52. The dust collection component 52 absorbs the raised concrete dust in time, and uses the vibration force to reduce the adhesion of dust to the suction port of the dust collection component 52, effectively preventing the powder from scattering everywhere and falling to the bridge deck for the second time to interfere with the maintenance work.

[0037] The anti-overflow device 5 also includes a plurality of vertical plates 55, a support rod 56 and a guide plate 57. The tops of the plurality of vertical plates 55 are symmetrical and fixedly mounted on the bottom edge of the dust collection assembly 52. ​​Both ends of the support rod 56 are fixedly mounted on the side of the vertical plate 55 close to the dust collection assembly 52. ​​The top of the guide plate 57 is hinged to the bottom of the bearing plate 1. The guide plate 57 penetrates through the inside and is hinged to the outer wall of the support rod 56. Through the above cooperation, the guide plate 57 continuously changes its inclination amplitude as the dust collection assembly 52 moves, so as to well shield and guide the concrete dust sucked by the dust collection assembly 52, thereby ensuring that the raised dust can be sucked into the dust collection assembly 52 in time, further avoiding the overflow of concrete dust and preventing the staff from inhaling concrete dust.

[0038] When in use, the fixed frame 42 moves downward and drives the transmission plate 51 to move synchronously when it is reset. The top of the transmission plate 51 is restricted by the dust suction component 52, which causes the hinge axis of the transmission plate 51 to start to rotate. At this time, the transmission plate 51 pulls the dust suction component 52 along the bottom of the supporting plate 1 with the hinge axis as the axis to slide toward the fixed frame 42. The dust suction component 52 drives the U-shaped square groove plate 53 to move synchronously. The arc surface of the top of the U-shaped square groove plate 53 contacts the inner wall of the arc groove at the bottom of the supporting plate 1 during the sliding process to generate a resistance force, thereby bending and deforming. When the U-shaped square groove plate 53 is freed from the resistance through its own arc surface and the arc surface guide of the arc groove, the U-shaped square groove plate 53 will swing back and forth to generate a vibration force when it is reset through its own toughness. At this time, the U-shaped square groove plate 53 causes the resonance sheet 54 inside it to vibrate synchronously, thereby increasing the vibration frequency. Through the above cooperation, the resonance sheet 54 is relied on to extend the vibration time of the U-shaped square groove plate 53, and at the same time, the transmission plate 51 expands the dust suction The movable range of the component 52, the dust suction component 52 absorbs the raised concrete dust in time, and uses the vibration force to reduce the adhesion of dust to the suction port of the dust suction component 52, effectively preventing the powder from scattering everywhere and falling to the bridge deck for the second time to interfere with the maintenance work; the dust suction component 52 drives the vertical plate 55 to move synchronously, the vertical plate 55 drives the support rod 56 to move synchronously, and the support rod 56 pulls the guide plate 57 to move synchronously, and the hinge axis between the top of the guide plate 57 and the bottom of the bearing plate 1 starts to rotate through the pulling force, and the guide plate 57 moves in an arc trajectory with the hinge axis as the axis toward the fixed frame 42. Through the above cooperation, the guide plate 57 continuously changes the inclination amplitude with the movement of the dust suction component 52, and the concrete dust sucked by the dust suction component 52 is well shielded and guided, ensuring that the raised dust can be sucked into the dust suction component 52 in time, further avoiding the overflow of concrete dust and preventing the staff from inhaling concrete dust.

[0039] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-residue device 6;

[0040] The anti-residue device 6 includes a circular frame 61, a friction plate 62, an elastic telescopic column 63 and a trapezoidal plate 64. The bottom of the circular frame 61 is hinged to the side of the guide plate 57 close to the U-shaped plate 46 through a torsion spring. The friction plate 62 is slidably installed on the outer wall of the filter plate 47 close to the U-shaped plate 46. The outer wall of the friction plate 62 is hinged to the top of the circular frame 61. The top of the elastic telescopic column 63 is fixedly installed on the bottom edge of the friction plate 62. The outer wall of the trapezoidal plate 64 is fixedly installed inside the telescopic end of the elastic telescopic column 63. The plate 64 is in contact with the outer wall of the filter plate 47 on one side close to the U-shaped plate 46. The above cooperation increases the scraping force of the trapezoidal plate 64 on the filter plate 47, preventing dirt from solidifying and corroding the surface of the filter plate 47 and shortening its service life. When the guide plate 57 is close to the filter plate 47, an angle is formed between the two, which facilitates the dust or actual particles scraped off the surface of the filter plate 47 to be absorbed by the dust collection component 52 in time, preventing dirt from scattering and adhering to or remaining on the surface of the filter plate 47, and preventing the dust from floating into the spray component 44 after falling off.

[0041] The anti-residue device 6 also includes a plurality of transmission wheels 65, a reciprocating screw rod 66, a protective shell 67 and a sponge block 68. The plurality of transmission wheels 65 are symmetrically and rotatably mounted on the inner wall of the fixed end of the elastic telescopic column 63. Both ends of the reciprocating screw rod 66 are fixedly mounted on one side of the transmission wheel 65 close to the axis of the circular frame 61. The protective shell 67 penetrates the inside and is movably mounted on the outer wall of the reciprocating screw rod 66. The outer wall of the sponge block 68 is fixedly mounted inside the protective shell 67.

[0042] The outer wall of the transmission wheel 65 contacts the outer wall of the filter plate 47, the top of the protective shell 67 is slidably connected to the bottom of the friction plate 62, and the sponge block 68 contacts the outer wall of the filter plate 47 away from the side of the circular frame 61. The above cooperation effectively expands the wiping range of the sponge block 68 on the surface of the filter plate 47, and the sponge block 68 timely absorbs the water droplets attached to the surface of the filter plate 47 due to splashing of the maintenance water source, thereby ensuring the dryness of the filter plate 47 and preventing the filter plate 47 from increasing the viscosity of the concrete dust due to the increase in humidity, thereby increasing the amount of adhesion, and causing the filter plate 47 to be more severely eroded.

[0043] When in use, the guide plate 57 moves in an arc trajectory, driving the circular frame 61 to move synchronously. The circular frame 61 is limited by the friction plate 62 to prompt its own hinge shaft to start rotating. At this time, the circular frame 61 will push the friction plate 62 to slide upward along the outer wall of the filter plate 47. The friction plate 62 continuously rubs the surface of the filter plate 47 during the sliding process. At the same time, the friction plate 62 drives the elastic telescopic column 63 to move synchronously. The elastic telescopic column 63 pulls the trapezoidal plate 64 to slide synchronously along the outer wall of the filter plate 47. When the trapezoidal plate 64 scrapes the outer wall of the filter plate 47 and is hindered by solidified dirt, the elastic telescopic column 63 continues to extend under the pull of the friction plate 62, and the spring inside itself is deformed synchronously to generate a restoring elastic force. Through the above cooperation, the scraping force of the trapezoidal plate 64 on the filter plate 47 is increased to prevent the dirt from solidifying and eroding the surface of the filter plate 47 and shortening its service life. When the guide plate 57 is close to the filter plate 47, an angle is formed between the two, which facilitates the dust or actual particles scraped off the surface of the filter plate 47 to be sucked by the dust collection group The parts 52 absorb the dirt in time to prevent the dirt from being scattered and attached or remaining on the surface of the filter plate 47, and prevent the dust from floating into the spray assembly 44 after falling off; when the telescopic end of the elastic telescopic column 63 moves, it drives the transmission wheel 65 to move synchronously, and the transmission wheel 65 rubs synchronously along the surface of the filter plate 47 and generates a rotational force, and the transmission wheel 65 drives the reciprocating screw 66 to rotate, and the reciprocating screw 66 limits the built-in block of the protective shell 67 through the reciprocating spiral groove of its own outer wall, so that the protective shell 67 can slide and reset along the bottom of the friction plate 62 on the outer wall of the reciprocating screw 66, and the protective shell 67 drives the sponge block 68 to wipe the surface of the filter plate 47. Through the above cooperation, the wiping range of the sponge block 68 on the surface of the filter plate 47 is effectively expanded, and the sponge block 68 timely absorbs the water droplets attached to the surface of the filter plate 47 due to the splashing of the maintenance water source, so as to ensure the dryness of the filter plate 47, and avoid the viscosity of the concrete dust on the filter plate 47 due to the increase of humidity, thereby increasing the adhesion amount, resulting in the erosion of the filter plate 47.
