Description

Technical Field

[0001] The utility model relates to the technical field of waterproof construction, in particular to a construction tool for waterproof coating. Background Technique

[0002] A waterproof coating refers to a coating that can prevent rainwater or groundwater from leaking. During the construction of a building, a layer of waterproof coating is applied to the walls or floors. However, during the application of the waterproof coating, the thickness of the waterproof layer formed after the application of the waterproof coating is uneven. Some places bulge thickly, and some places are sunken thinly. This will cause the waterproof performance of the floor or wall to decline, resulting in the phenomenon of uplift of the floor or wall, affecting the service life of the cement floor or wall, and at the same time affecting the aesthetics of the cement floor or wall.

[0003] For example, in a construction site, since the scaffold needs to be fixedly connected to the wall using steel pipes, after the steel pipes are removed later, the exterior wall needs to be coated with paint to avoid subsequent leakage. However, when most of the existing coating tools are in operation, manual brushes or roller brushes are used to paint the waterproof coating on the places prone to leakage. Since the exterior walls of construction sites are prone to unevenness, construction workers need to replace shovels to shovel off the protruding concrete on the exterior wall. However, since the concrete adheres relatively firmly, it is difficult for construction workers to manually clean it.

[0004] Secondly, in a construction site, due to the narrow space at the connection position between the steel pipe and the exterior wall, construction workers cannot enter, resulting in the inability to paint with a brush. For example, a construction tool for waterproof coating (publication number: CN217734724U) involves the technical field of waterproof coating construction, including a handle with a connecting piece thereon. During the use of the above patent, it needs to be held by a construction worker to operate, and it can only face some places with good space. When facing some narrow spaces, the above patent cannot operate, making the construction tool of the above patent have limitations. Moreover, most of the existing construction tools that can be lengthened can only increase the length during operation and cannot adjust the angle, so they have great limitations during use. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0029] A waterproof coating construction tool, including a second vertical rod 2. A third vertical rod 3 is slidably installed inside the second vertical rod 2. The right end of the third vertical rod 3 is located outside the second vertical rod 2. A spatula 52 is slidably installed at the right end inside the third vertical rod 3. The right end of the spatula 52 is located outside the third vertical rod 3. A plurality of support rods 61 are rotatably installed at the upper right end of the third vertical rod 3. A roller brush 62 is rotatably installed at the right end inside the support rod 61. A second motor 5 is fixedly installed at the right end inside the third vertical rod 3. A connecting rod 51 is fixedly installed on the output shaft of the second motor 5. The right end of the connecting rod 51 is rotatably connected to the left end of the spatula 52. A hinge support 6 is fixedly installed at the upper right end of the third vertical rod 3. The left ends of the plurality of support rods 61 are rotatably installed inside the hinge support 6.

[0030] By adopting the above technical solution, during the process of applying waterproof coating on the market, a brush or a roller is required for operation. However, most of the construction tools on the market are in a handheld state during operation. Secondly, during the use process, the length can be increased. But the traditional tools will encounter the following situations during operation: For example, in a construction site, due to a large amount of concrete remaining on the wall, cleaning is required. At this time, the construction worker needs to replace the tool to carry out the operation, and the process is cumbersome. Secondly, in a construction site, due to the reason of the building main body, the construction space at some corner positions is narrow. The construction workers can only lengthen the tool to carry out the operation, and then need to replace the tool back and forth, resulting in a long operation time and each operation requires withdrawing the original tool to replace another tool, and the process is relatively cumbersome; The structure of this device is as follows, including a U-shaped rod 1. The right end of the U-shaped rod 1 is in an open state. Parallel chutes 11 are provided on the inner side wall of the U-shaped rod 1. And a first installation hole 12 is provided at the right end of the U-shaped rod 1. A second vertical rod 2 is slidably installed inside the U-shaped rod 1. Two sliding platforms 22 are fixedly installed on the front and rear end faces of the second vertical rod 2. The sliding platforms 22 are slidably installed inside the chutes 11, so that the second vertical rod 2 will not fall out of the inside of the U-shaped rod 1 and can only slide horizontally inside the U-shaped rod 1. Secondly, a second installation hole 21 is provided at the left end of the second vertical rod 2. When the second installation hole 21 at the left end of the second vertical rod 2 is aligned with the first installation hole 12, the U-shaped rod 1 and the second vertical rod 2 can be fixedly connected together by using a pin 13, so that the combined length of the U-shaped rod 1 and the second vertical rod 2 is longer. Secondly, the U-shaped rod 1 and the second vertical rod 2 can be combined into an L-shaped structure by using the pin 13.

[0031] In addition, a first battery 23 is installed at the right end of the second socket 21 inside the second vertical rod 2. Next, a first motor 24 is fixedly installed inside the second vertical rod 2 at the right end of the first battery 23. A screw rod 25 is fixedly installed on the output shaft of the first motor 24 (wherein, a groove is formed in the second vertical rod 2 from the right end to the inside, and the first motor 24 is located on the left end face inside the groove). A third vertical rod 3 is slidably installed inside the second vertical rod 2. The left end of the third vertical rod 3 is provided with a screw hole 31. Moreover, the inside of the third vertical rod 3 is in a cavity state. And the right end of the screw rod 25 passes through the screw hole 31 and is located inside the third vertical rod 3. Next, a cavity is arranged at a position near the edge at the right end inside the third vertical rod 3. A second battery 4 is arranged inside the cavity. Then, a second motor 5 is fixedly installed inside the third vertical rod 3 at the right end of the second battery 4. A vertical plate is fixedly installed on the output shaft of the second motor 5. A connecting rod 51 is rotatably installed on the rear end face of the upper part of the vertical plate. The right end of the connecting rod 51 is rotatably installed with a scraper 52. The right end of the scraper 52 is located outside the third vertical rod 3. A hinge support 6 is fixedly installed at a position near the edge at the upper right end of the third vertical rod 3. Two support rods 61 are rotatably installed inside the hinge support 6. A rotary brush 62 is rotatably installed inside the right end of the support rod 61. During use, the second vertical rod 2 is pulled out so that the second socket 21 at the left end of the second vertical rod 2 is aligned with the first socket 12 at the right end of the U-shaped rod 1. Then, it is determined whether to increase the length or combine the U-shaped rod 1 and the second vertical rod 2 into an L-shaped structure according to the on-site requirements. Then, the U-shaped rod 1 and the second vertical rod 2 are fixed by using a pin 13. Next, the first motor 24 is started. The output shaft of the first motor 24 will drive the screw rod 25 to rotate synchronously. During the rotation of the screw rod 25, the third vertical rod 3 will be driven to gradually slide out of the inside of the second vertical rod 2. When the right end of the screw hole 31 in the third vertical rod 3 fits with the right end of the screw rod 25, the third vertical rod 3 will stop moving. At this time, the combined length of the second vertical rod 2 and the third vertical rod 3 is in the longest state. Then, when facing the remaining concrete on the wall, the second motor 5 is started. The output shaft of the second motor 5 will drive the connecting rod 51 to move, so that the connecting rod 51 will drive the scraper 52 to perform a linear reciprocating motion, so as to enable the scraper 52 to scrape off the concrete on the wall. Then, the U-shaped rod 1 is rotated so that the second vertical rod 2 and the third vertical rod 3 rotate synchronously, so as to enable the circumferential surface of the rotary brush 62 to be in contact with the front surface, thereby performing the painting of the coating;Compared with the traditional painting devices on the market, the present device can shovel the concrete left in front of the construction site in cooperation with the above structure, so as to ensure the painting of the waterproof coating on the wall and avoid leakage in the later stage. Secondly, during the use process, since the scraper 52 and the roller brush 62 are in the same position, the construction workers do not need to put down the scraper 52 and pick up the brush back and forth, which is so cumbersome. After the scraper 52 finishes its operation, only the angle needs to be adjusted, and then the roller brush 62 can be used for operation, saving a lot of time.

[0032] Specifically, as Figures 1 to 5 shown, a second battery 4 is arranged on the left side of the second motor 5 at the right end inside the third vertical rod 3. A screw hole 31 is formed from the left end to the inside of the third vertical rod 3. A first battery 23 is arranged at the left end inside the second vertical rod 2. A first motor 24 is fixedly installed at the right end of the first battery 23 inside the second vertical rod 2. A screw 25 is fixedly installed on the output shaft of the first motor 24. The right end of the screw 25 extends into the inside of the third vertical rod 3. Slide tables 22 are fixedly installed at the positions near the edges at the left and right ends on the outside of the second vertical rod 2. The second vertical rod 2 is slidably installed inside the U-shaped rod 1. A chute 11 is formed on the inner side wall of the U-shaped rod 1. The slide table 22 is slidably installed inside the chute 11. A first socket 12 is formed at the right end of the U-shaped rod 1. A second socket 21 is formed at the left end of the second vertical rod 2. A pin 13 is arranged on the outside of the right end of the U-shaped rod 1.

[0033] By adopting the above technical solution, during the use of traditional waterproof coating construction tools on the market, due to height reasons, construction workers will install a vertical rod so that the brush can reach the working area. However, most traditional heightening devices on the market are installed in a straight line, which leads to the fact that during use, traditional devices on the market can only increase the length simply. When the device faces a narrow space and inconvenient angles for operation, the device has limitations. Compared with traditional devices on the market, during the use of this device, on the one hand, it can increase the length of the device, and on the other hand, during use, the roller brush 62 can be in a vertical or inclined state with the third vertical rod 3, so that the roller brush 62 can be applied to different wall corners. Secondly, during use, the U-shaped rod 1 and the second vertical rod 2 can also be combined into an L-shaped structure or an obtuse angle shape, so that the device can be applied to different walls and exterior walls. Because during use, when facing a wall corner, when the construction worker stands on the ground for construction, the paint is likely to fall on the person, affecting the safety of the construction worker. Therefore, during use, to avoid the paint falling on the construction worker, the device structure can be adjusted according to the on-site requirements, so that the construction worker can stay away from the lower part of the construction point during construction and still be able to carry out construction. Secondly, when facing the exterior wall, since the construction point is inconvenient for the person to stand and it is inconvenient for the construction worker to operate with a straight rod and a brush, therefore, the angle of the above device structure can be adjusted according to the on-site requirements to complete the painting operation. With the cooperation of structures such as the U-shaped rod 1, the second vertical rod 2, and the third vertical rod 3, the roller brush 62 can also operate when facing a narrow space, and during operation, the device can change the angle, making the third vertical rod 3 and the roller brush 62 form an L-shaped structure, so as to be applicable to different angles. Compared with the above patents, this device can adjust the length and angle according to different painting places to meet the construction requirements.

[0034] Working principle: First, pull out the second vertical rod 2 to combine the U-shaped rod 1 and the second vertical rod 2 into the required shape.

[0035] Then start the first motor 24, and the output shaft of the first motor 24 drives the screw rod 25 to rotate, so that the left end of the third vertical rod 3 gradually moves away from the first motor 24.

[0036] Secondly, start the second motor 5, and the output shaft of the second motor 5 drives the connecting rod 51 to move, so that the shovel 52 performs a linear motion to achieve the operation of shoveling concrete.

[0037] Finally, make the roller brush 62 fit the exterior wall to carry out the painting of the waterproof coating, so as to complete the construction operation.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
