Description

Technical Field

[0001] The invention relates to a maintenance device, in particular to an automatic spraying and atomizing maintenance device for a bridge tower. Background Art

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. If the surrounding environment does not have such conditions, artificial curing of concrete is required. Concrete curing methods include the most easily achieved natural curing.

[0003] Natural curing includes watering curing and spraying plastic film curing. The former covers the concrete with straw mats and keeps it moist by sprinkling water frequently. The curing time depends on the type of cement, such as ordinary Portland cement concrete for no less than 7 days and nights. The latter is suitable for high-rise structures and large-area concrete structures that are not easy to be cured by watering. It is to spray the perchlorethylene resin plastic solution on the concrete surface with a spray gun. After the solution evaporates, a thin film is formed on the concrete surface, isolating the concrete from the air, preventing the evaporation of water in the concrete, and ensuring the normal hydration of cement. After the curing is completed, the film will age and fall off by itself.

[0004] In the maintenance process of bridge towers, perchlorethylene resin plastic solution is often used to spray on the building surface with a spray gun. The existing equipment has many limitations when spraying, such as inconvenient height adjustment and lack of guarantee of spraying uniformity.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] Example 1: Please refer to Figure 1-3 An automatic spraying and spraying maintenance device for a bridge tower comprises a fixed bottom plate 1 and a movable bottom plate 2, wherein a universal wheel 9 is fixedly connected to the bottom of the fixed bottom plate 1. A height adjustment component 3 is arranged between the fixed bottom plate 1 and the movable bottom plate 2, a mixing box 4 is fixedly connected to the movable bottom plate 2, a mixing component 5 is arranged in the mixing box 4, an atomizing spray component 6 is arranged above the movable bottom plate 2, the atomizing spray component 6 comprises a spray pipe 7, the spray pipe 7 is connected to the mixing box 4 through a hose, and a spray nozzle 8 is fixedly connected to the end of the spray pipe 7.

[0027] When in use, the device is moved to the position of the bridge tower that needs to be maintained, and the raw materials for preparing the perchlorethylene resin plastic solution are placed inside the mixing box 4. Then the mixing component 5 can be opened. The mixing component 5 fully stirs the solution before spraying it on the bridge tower, and the atomizing spray component 6 can spray the mixed solution.

[0028] The height adjustment assembly 3 includes a first motor 10 fixed above the fixed base plate 1, the first motor 10 is a dual-axis motor, and a bidirectional screw 11 is fixedly connected to the output end of the first motor 10, a lower slider 12 is slidably connected above the fixed base plate 1, an upper slider 13 is slidably connected below the movable base plate 2, a cross-linking rod group 14 is connected between the lower slider 12 and the upper slider 13, the bidirectional screw 11 is threadedly connected to the lower sliders 12 on both sides, a telescopic guide rod 15 is fixedly connected to the middle part below the movable base plate 2, and the end of the telescopic guide rod 15 is rotatably connected to the cross-linking rod group 14 at a hinge position.

[0029] During the spraying process, since the height of the bridge tower is generally high, it is necessary to open the height adjustment component 3, supply power to the first motor 10 and control the direction of the first motor 10, and the rotation of the first motor 10 drives the bidirectional screw 11 to rotate, and the rotation of the bidirectional screw 11 can drive the lower slider 12 to move, and the lower slider 12 will synchronously drive the cross-link group 14, the upper slider 13 and the telescopic guide rod 15 to move, and the telescopic guide rod 15 can play a guiding role, so that the upper slider 13 and the lower slider 12 can move symmetrically along the center line direction.

[0030] Embodiment 2: This embodiment further makes the following improvements on the basis of the previous embodiment: the mixing component 5 includes a liquid pump 16 fixed on the movable bottom plate 2, the liquid inlet of the liquid pump 16 is connected to the water inlet pipe 17, the liquid outlet of the liquid pump 16 is connected to the water outlet pipe 18, the end of the water outlet pipe 18 is connected to a power nozzle 19, the mixing shaft is rotatably connected to the inside of the mixing shaft, the outside of the stirring shaft 20 is fixedly connected to a driven rotating plate 21, the power nozzle 19 cooperates with the driven rotating plate 21, and the bottom outside of the stirring shaft 20 is fixedly connected to a spiral blade 22.

[0031] When the mixing component 5 is working, the liquid pump 16 is turned on, and the liquid pump 16 drives the solution to reflux. During the reflux process, it can be fully mixed. The refluxed liquid is sprayed out after passing through the power nozzle 19. During the spraying process, the driven rotating plate 21 is driven to rotate, and then the stirring shaft 20 is driven to rotate, thereby further ensuring the uniformity of the solution.

[0032] The top of the mixing box 4 is provided with an injection port 23, and the power nozzle 19 is located at one side of the injection port 23. The liquid sprayed by the power nozzle 19 passes under the injection port 23. When raw materials are added during the solution preparation process, mixing will be carried out simultaneously, thereby increasing the mixing speed.

[0033] The end of the water inlet pipe 17 is a flexible pipe, which changes position with the movement of the water flow, thereby promoting uniform mixing of the solution.

[0034] The atomizing spray assembly 6 includes a telescopic guide plate 24, a nozzle 7 is fixed on the top of the telescopic guide plate 24, a second motor 25 is fixedly connected to the movable bottom plate 2, a height adjustment screw 26 is fixedly connected to the rotor of the second motor 25, and the telescopic guide plate 24 is threadedly connected to the height adjustment screw 26.

[0035] A three-way diversion solenoid valve 27 is fixedly connected to the middle of the water outlet pipe 18, and the nozzle 7 is connected to the three-way diversion solenoid valve 27. A sensing cross bar 28 is fixedly connected to the middle of the telescopic guide plate 24. When the sensing cross bar 28 moves, the three-way diversion solenoid valve 27 switches the flow direction, allowing the liquid to flow into the nozzle 7.

[0036] The telescopic guide plate 24 includes a symmetrically arranged fixed side plate 29, which is fixedly connected to the movable bottom plate 2, and a primary adjustment plate 30 is slidably connected to the inner side of the fixed side plate 29, and a secondary adjustment plate 31 is slidably connected to the inner side of the primary adjustment plate 30, and the secondary adjustment plates 31 are fixedly connected by a driven cross plate 32, the height adjustment screw 26 is threadedly connected to the driven cross plate 32, and the nozzle 7 is fixed on the driven cross plate 32.

[0037] When liquid spraying is required, the first motor 25 is turned on. After the first motor 25 is turned on, it drives the height adjustment screw 26 to rotate, and then drives the telescopic guide plate 24 to rise. At this time, the sensing cross bar 28 moves upward. When the three-way diversion solenoid valve 27 senses the upward movement of the sensing cross bar 28, the solution is guided to the atomizing spray assembly 6 through the hose to spray the bridge tower. The telescopic guide plate 24 can be retracted by rotating the first motor 25 in the opposite direction.

[0038] A control cabinet 33 is fixedly connected to the movable floor, and the three-way flow-dividing solenoid valve 27 , the first motor 10 , the second motor 25 and the liquid pump 16 are electrically connected to the control cabinet 33 , respectively.

[0039] Working principle: When in use, move the device to the position of the bridge tower that needs to be maintained, place the raw materials for preparing the perchlorethylene resin plastic solution inside the mixing box 4, and then open the mixing component 5. The mixing component 5 fully stirs the solution before spraying it on the bridge tower, and the atomizing spray component 6 can spray the mixed solution. During the spraying process, since the height of the bridge tower is generally high, it is necessary to open the height adjustment component 3, supply power to the first motor 10 and control the direction of the first motor 10. The rotation of the first motor 10 drives the bidirectional screw 11 to rotate, and the rotation of the bidirectional screw 11 can drive the lower slider 12 to move. The lower slider 12 will synchronously drive the cross-link group 14, the upper slider 13 and the telescopic guide rod 15 to move. The telescopic guide rod 15 can play a guiding role, so that the upper slider 13 and the lower slider 12 can move symmetrically along the center line direction. When the mixing component 5 is working, the liquid pump 16 is turned on, and the liquid pump 16 drives the solution to reflux. During the reflux process, the solution can be fully mixed. The refluxed liquid is sprayed out after passing through the power nozzle 19. During the spraying process, the driven rotating plate 21 is driven to rotate, and then the stirring shaft 20 is driven to rotate, further ensuring the uniformity of the solution. When it is necessary to spray the liquid, the second motor 25 is turned on. After the second motor 25 is turned on, it drives the height adjustment screw 26 to rotate, and then drives the telescopic guide plate 24 to rise. At this time, the sensing crossbar 28 moves upward. When the three-way diversion solenoid valve 27 senses the upward movement of the sensing crossbar 28, the solution is guided to the atomizing spray component 6 through the hose to spray the bridge tower. The telescopic guide plate 24 can be retracted by rotating the second motor 25 in the opposite direction.
