Description

Technical Field

[0001] The present invention relates to the technical field of paint spraying, and particularly relates to a roof automatic spraying and renovation device. Background Art

[0002] With the development of urbanization, after a building is completed, in order to avoid roof leakage, a waterproof coating spraying device is used to perform waterproof treatment on the building. The principle of the waterproof coating spraying device is to pressurize a container through a booster pump, and then directly spray the pressurized waterproof coating. The latex paint sprayed from the spray gun is in a mist state and can be evenly adhered and adsorbed by the wall.

[0003] Currently, when performing waterproof spraying construction on the roof, it is basically carried out by manually holding the device to spray on the roof. During spraying, the operation is flexible, and it is convenient for carrying, transporting, and moving. On the other hand, for example, the invention patent with the publication number CN218862023U discloses a spraying instrument for waterproof coating. By setting a cleaning box, an air chamber, a collection box, etc., while moving the main body of the spraying device, the sand and ash on the roof surface are sucked into the interior of the air chamber, and the roof is cleaned before spraying to enhance the firmness. Spraying is carried out while the trolley is moving, with high efficiency, and combined with dust removal before spraying, the construction efficiency is further improved.

[0004] However, during manual operation, due to the fatigue and high-intensity work caused by long-term hand-held work, when spraying, the distance between the spraying end of the device and the floor surface cannot be continuously maintained at a certain height, there will be height differences, resulting in uneven spraying. When spraying with a trolley, although the distance between the spraying end and the floor surface can be kept constant to maintain the uniformity of paint spraying, in actual application, the path of the walking wheels during spraying will overlap with the spraying part, resulting in the trolley damaging the sprayed surface during spraying, thereby affecting the uniformity of the paint after spraying.

[0010] According to some embodiments of the present invention, two sets of running wheels are provided on each of the two sides of the spray frame, and one set of running wheels is located in the middle of the length direction of the spray frame, and the other set is located on the side away from the feeding piece.

[0011] According to some embodiments of the present invention, the spraying plates are provided in two groups and are slidably arranged on the balance plate, and an elastic member is provided on the side of the spraying plate close to the feed piece, and a toggle column is provided on the side of the spraying plate away from the feed piece.

[0012] According to some embodiments of the present invention, an auxiliary component is also included, which includes a driven gear rotatably set on the spray frame and a pulley transmission component drivingly connected to the driven gear, a protrusion is provided on the pulley at one end of the pulley transmission component close to the spray plate, and a driving gear that can be meshed with the driven gear is coaxially installed on the walking wheel.

[0013] According to some embodiments of the present invention, a protective component is also included, which includes an exhaust plate arranged outside the spray frame and connected to the interior, and a rotating blade coaxially connected to the rotating shaft of the walking wheel is provided in the exhaust plate, an exhaust groove is provided on the side of the exhaust plate close to the rotating blade, and an adsorption component is provided on the side of the exhaust plate close to the spray frame.

[0015] Beneficial Effects Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1.

Even if the drive button on the handrail is pressed by mistake, the paint cannot be sprayed out, thereby improving protection. During construction and when the running wheels rotate, the rotating blades and adsorbents are cooperated to filter the paint particles generated when the paint is sprayed, thereby improving the construction environment.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Refer to the attached Figures 1-9 , an automatic spraying renovation device for a roof, including a device body 1, a handrail for an operator to take is provided on the device body 1, the operator drives the device to move and spray by holding the handrail, the handrail is provided with a feeding pipe connected to an external feeding container and a driving button for controlling the output of the paint in the feeding container, the pump in the feeding container is started by pressing the driving button, and the paint is input into the feeding pipe, which is a relatively conventional prior art, and will not be described in detail here, and also includes: A spraying frame 2 is located at the bottom of the equipment body 1, and a 21 is elastically installed at the bottom of the spraying frame 2, and a limiting column 211 extending into the spraying frame 2 is provided on the walking wheel 21, and the walking wheel 21 is slidably arranged on the spraying frame 2 through the limiting column 211, and a spring is provided between the walking wheel 21 and the spraying frame 2, and the walking wheel 21 is provided with multiple groups and symmetrically distributed on both sides of the moving direction of the spraying frame 2, and the shape of the limiting column 211 is not restricted, preferably prismatic, to prevent relative rotation between the walking wheel 21 and the spraying frame 2, and the spring is used to always push the walking wheel 21 away from the spraying frame 2, and when both groups of walking wheels 21 are in contact with the ground, the spring squeezes and compresses so that the limiting column 211 extends into the spraying frame 2; The spraying assembly 3 located within the spraying frame 2 includes a balance plate 31 rotatably arranged on the spraying frame 2 and a feeding member 33 communicated with an external feeding device. A spraying plate 32 is provided at the bottom of the balance plate 31. A turntable 34 is coaxially installed on one side of the balance plate 31, and the turntable 34 is rotatably connected to the feeding member 33. The feeding member 33 is provided with a feeding hole 331, and the turntable 34 is provided with a connecting hole 341. There are two groups of feeding holes 331 on the feeding member 33 and they are symmetrically distributed on both sides of the connecting hole 341. An arc-shaped connecting groove is provided on the side of the feeding hole 331 close to the turntable 34. When the balance plate 31 is tilted, it drives the turntable 34 to rotate, thereby connecting the connecting hole 341 with the feeding hole 331, achieving automatic opening during operation and closing in a non-operating state, preventing the paint from spraying out from the spraying plate 32 during non-operation due to misoperation. When both sets of traveling wheels 21 are in contact with the ground, the spring is compressed and the limiting post 211 extends towards the bottom of the balance plate 31 to limit the rotation of the balance plate 31.

[0022] Furthermore, a counterweight is provided on the spraying plate 32, and multiple groups of nozzles 321 are provided at equal intervals at the bottom end of the spraying plate 32. The spraying direction of the nozzles 321 faces the ground. Due to the setting of the counterweight on the spraying plate 32, when the equipment rotates and tilts along the central axis of the traveling wheels 21, the spraying plate 32 can always remain perpendicular to the ground. Furthermore, it can prevent the distance between the spraying plate 32 and the ground from changing when the inclination angle of the equipment changes within a certain range, improving the uniformity and stability of paint spraying.

[0023] In the above technical solution, in the non-operating state, the traveling wheels 21 on the spraying frame 2 are all in contact with the ground. At this time, the limiting post 211 extends into the spraying frame 2 and abuts against the bottom of the balance plate 31 to limit the rotation of the balance plate 31. At this time, the connecting hole 341 cannot be communicated with the feeding hole 331. Even if the driving button on the armrest is accidentally pressed, the paint cannot be sprayed out. When spraying is required, the spraying frame 2 is tilted through the armrest, so that the traveling wheels 21 on one side of the spraying frame 2 are in contact with the ground, and the traveling wheels 21 on the opposite side are separated from the ground and drive the limiting post 211 to retract under the action of the spring and cancel the restriction on the balance plate 31. At this time, the balance plate 31, in cooperation with the spraying plate 32, always remains parallel to the ground, maintaining the distance between the nozzles 321 on the spraying plate 32 and the ground. The turntable 34 on the balance plate 31 rotates relative to the feeding member 33 to connect the connecting hole 341 with the feeding hole 331. While pushing the spraying frame 2 to move through the armrest, the driving button is pressed to input the paint into the spraying plate 32 for spraying construction. The distance between the spraying plate 32 and the ground remains vertically downward to a certain extent, improving the uniformity of paint spraying.

[0024] Among them, two sets of walking wheels 21 are provided on each of the two sides of the spray frame 2 to maintain the stability and convenient operation of the equipment during operation, and one set of walking wheels 21 is located in the middle position of the length direction of the spray frame 2, and the other set is located on the side away from the feeding piece 33. Due to the special arrangement of multiple sets of walking wheels 21 on the spray frame 2, one side of the spray frame 2 is suspended. During continuous spraying construction, space will be left to prevent the walking wheels 21 from damaging the sprayed paint during movement. Since the paint is sprayed from the end of the feeding piece 33 throughout the entire spray plate 32, the paint will preferentially enter the spray plate 32 from the end of the spray frame 2 where the walking wheels 21 are not provided. At the same time, the walking wheels 21 can be used to fully spray the adjacent spraying areas to prevent the generation of spraying gaps and improve the spraying effect.

[0025] In addition, two groups of spray plates 32 are provided and are slidably arranged on the balance plate 31, and an elastic member 322 is provided on the side of the spray plate 32 close to the feed member 33, and a toggle column 323 is provided on the side away from the feed member 33. The spray plate 32 is kept in a relatively stable state by the elastic member 322, and the elastic member 322 is intermittently squeezed by squeezing the toggle column 323 to push the spray plate 32 to realize the swing of the spray plate 32, and then cooperate with the multiple groups of spraying on the spray plate 32 to minimize the concentration of the spraying of the nozzle 321, thereby further improving the uniformity of the coating.

[0026] In addition, an auxiliary component 22 is also included. The auxiliary component 22 includes a driven gear 221 rotatably arranged on the spray frame 2. The driven gear 221 is arranged on the spray frame 2 through a protective cover, and the driven gear 221 is driven and connected to a pulley transmission component 222. The pulley transmission component 222 is composed of two groups of pulleys and a group of belts. A protrusion 2201 is provided on the pulley at one end of the pulley transmission component 222 close to the spray plate 32, and the protrusion 2201 is provided with a plurality of groups. The pulley of the pulley transmission component 222 close to the driven gear 221 is connected to the The driven gear 221 is coaxially connected, and the traveling wheel 21 is coaxially installed with a driving gear 212 that can be meshed with the driven gear 221. When the traveling wheel 21 squeezes and approaches the spray frame 2, that is, when the limiting column 211 extends into the spray frame 2, the driving gear 212 meshes with the driven gear 221, and then when the spray frame 2 is pushed to move, due to the rotation of the traveling wheel 21, the driven gear 221 and the pulley transmission assembly 222 are cooperated to drive the protrusion 2201, and then the spray plate 32 is intermittently moved to achieve the staggered sliding of the two groups of spray plates 32.

[0027] In the above technical solution, through the special setting of the traveling wheels 21 on the spraying frame 2, one side of the spraying frame 2 is suspended during spraying. Further, during multiple spraying processes, it prevents the traveling wheels 21 from contacting the ground and affecting the sprayed paint. Further, when the traveling wheels 21 contact the ground, they drive the driving gear 212 to mesh with the driven gear 221, and then cooperate with the belt drive assembly 222 to make the traveling wheels 21 rotate multiple sets of protrusions 2201 when rotating, intermittently extruding the two spraying plates 32, realizing the staggered movement of the two spraying plates 32, preventing the situation of local over-thickness caused by the fixed spraying of the nozzle 321, and further improving the uniformity of the nozzle 321 during spraying.

[0028] It should be noted that it further includes a protection component 23. The protection component 23 includes an air extraction plate 231 arranged outside the spraying frame 2 and communicating with the inside. The top of the air extraction plate 231 extends into the spraying frame 2 and is located above the balance plate 31, and a rotating blade 232 coaxially connected to the rotating shaft of the traveling wheel 21 is arranged in the air extraction plate 231. An exhaust groove 2301 is arranged on one side of the air extraction plate 231 close to the rotating blade 232. When the spraying frame 2 is spraying, since paint particles will be dispersed into the air when the paint is sprayed rapidly, at this time, the traveling wheels 21 rotate and drive the rotating blade 232 to rotate, and then the gas in the spraying frame 2 is pumped towards the air extraction plate 231 and discharged through the exhaust groove 2301. During the pumping process, the dispersed paint particles are pumped into the air extraction plate 231. Since an adsorbent 233 is arranged on one side of the air extraction plate 231 close to the spraying frame 2, when the gas extracted from the spraying frame 2 passes through the adsorbent 233, it is adsorbed to improve the construction site environment and reduce the dispersion degree of paint particles on site.

[0029] Working principle: The handrail on the equipment body 1 drives the spray frame 2 to rotate along the walking wheel 21 on one side. The walking wheel 21 on the opposite side of the spray frame 2 extends out under the action of the spring and drives the limit column 211 away from the balance plate 31, canceling the restriction on the balance plate 31. At this time, the balance plate 31 and the spray frame 2 rotate relative to each other, and are always parallel to the ground under the action of the spray plate 32. The turntable 34 and the feeding piece 33 arranged on one side of the balance plate 31 rotate relative to each other to achieve the connection between the connecting hole 341 and the feeding hole 331. At this time, the spray frame 2 is pushed or pulled and the driving button is pressed to guide the paint into the spray plate 32 to spray the floor. Due to the special arrangement of the walking wheel 21 on the spray frame 2, one side of the spray frame 2 is suspended during spraying, and then in the process of multiple spraying, the walking wheel 21 is prevented from contacting the ground and affecting the paint after spraying. At the same time, the driving gear 212 on the walking wheel 21 for support is meshed with the driven gear 221. 1 is rotated to drive the protrusion 2201, and the intermittent squeezing of the spray plate 32 by the toggle column 323 is realized to realize the staggered movement of the two groups of spray plates 32, so as to prevent the local over-thickness caused by the fixed spraying of the nozzle 321, and further improve the uniformity of the spraying of the nozzle 321. In addition, during the spraying construction process, since the paint is sprayed out quickly, paint particles will be scattered into the air, and the rotating walking wheel 21 drives the rotating blade 232 to extract the gas in the spray frame 2 and discharge it from the exhaust groove 2301. During the extraction process, the adsorbent 233 on the exhaust plate 231 is cooperated to filter the paint particles, and further improve the environment of the construction site. When in the non-construction state, the walking wheels 21 on both sides of the spray frame 2 are in contact with the ground, and then the limiting column 211 is extended into the spray frame 2 to press against the balance plate 31, and the rotation of the balance plate 31 is limited to block the feeding end of the spray plate 32, so as to prevent the paint from being sprayed out in the non-working state due to the misoperation of the driving button.
