Roughening of waterproof coating is a key step in waterproof construction. It requires special treatment on the base layer that has been coated with waterproof coating to increase the roughness and adhesion of the base layer. The base layer needs to be treated before applying the waterproof coating. It is necessary to ensure that the base layer is clean, flat, free of oil and loose matter to avoid peeling of the waterproof coating after drying.

Obviously, the described embodiments are only 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.

[0032] like Figures 1 to 10As shown, the present invention provides an auxiliary device for roughening a waterproof coating, comprising a positioning support frame 1, a flip connecting frame 2 is rotatably connected to the middle part of the positioning support frame 1, a limiting support frame 3 is fixedly connected inside the positioning support frame 1, a limiting slider 4 is fixedly connected to one side of the limiting support frame 3, a cleaning component 5 is arranged on the side of the limiting support frame 3 close to the limiting slider 4, a support wheel 6 is rotatably connected to the side of the positioning support frame 1 away from the limiting support frame 3, a friction driving wheel group 7 is rotatably connected to the middle part of the limiting support frame 3, and a transmission component 8 is arranged inside the limiting support frame 3.

[0033] The above scheme is adopted: by pushing the friction driving wheel group 7 to move up and down, the friction driving wheel group 7 drives the bristle fixing plate 51 to slide up and down to clean the wall surface, and at the same time, the friction driving wheel group 7 will rotate with the wall surface, so that the friction driving wheel group 7 will synchronously drive the turbine 85 to rotate, and the turbine 85 drives the vortex rod 81 to rotate, so that the vortex rod 81 can drive the vortex rods 81 at both ends to rotate, thereby driving the transmission connecting rod 83 to rotate, so that the transmission connecting rod 83 continuously pushes and pulls the transmission push-pull rod 84 to move, and at this time the transmission push-pull rod 84 will drive the bristle fixing plate 51 to move, so that the bristle fixing plate 51 cleans the wall surface with the hard bristles 52. When the upper side of the wall surface is cleaned, the friction driving wheel group 7 and the supporting wheel 6 can be reversed and moved downward from the middle to clean the lower half of the wall.

[0034] like Figure 2 , Figure 3 and Fig.10 As shown, the positioning support frame 1 is E-shaped, the limiting support frame 3 is fixedly connected to the connecting rod extending from the middle of the positioning support frame 1, the connecting rods at both ends of the positioning support frame 1 are rotatably connected to the friction drive wheel group 7, the flip connecting frame 2 is located on the side of the positioning support frame 1 away from the cleaning component 5, and a connecting port is provided at the end of the flip connecting frame 2 away from the positioning support frame 1, two pairs of cross-distributed support rods are arranged in the middle of the limiting support frame 3, the limiting slider 4 is located on the side of the limiting support frame 3 close to the cleaning component 5, and is mirror-distributed at both ends of the limiting support frame 3, and the limiting support frame 3 is rotatably connected to the friction drive wheel group 7 through a pair of support rods.

[0035] The above scheme is adopted: by setting a positioning support frame 1, the positioning support frame 1 fixes the limit support frame 3, and the positioning support frame 1 is rotatably connected with the friction drive wheel group 7, so that the friction drive wheel group 7 can drive the positioning support frame 1 and the limit support frame 3 to move, and the flip connection frame 2 arranged on the positioning support frame 1 can conveniently provide a light long pole connected to the connection hole opened on the flip connection frame 2, and then the friction drive wheel group 7 can be pushed up and down along the wall by the long pole. The support wheel 6 arranged in the middle of the positioning support frame 1 enables the flip connection frame 2 to always be in close contact with the wall when the friction drive wheel group 7 is pushed by the positioning support frame 1 to move;

[0036] Two pairs of support rods arranged inside the limiting support frame 3 are rotatably connected to the friction drive wheel group 7 and the worm rod 81 respectively, so as to limit the friction drive wheel group 7 and the worm rod 81. At the same time, the limiting slider 4 arranged on the limiting support frame 3 is used to support and limit the cleaning component 5, so that the cleaning component 5 can move horizontally back and forth while moving, and keep parallel to the wall.

[0037] like Figure 3 , Figure 5 and Figure 6 As shown, the cleaning assembly 5 includes a bristle fixing plate 51, one side of the bristle fixing plate 51 is fixedly connected with hard bristles 52, both ends of the bristle fixing plate 51 are provided with roller placement openings 53, one side of the bristle fixing plate 51 away from the hard bristles 52 is fixedly connected with a limiting slide 54, and one end of the bristle fixing plate 51 is fixedly connected with a pair of fixing seats 55.

[0038] The above scheme is adopted: by setting up a cleaning component 5, the fixed seat 55 pulls the bristle fixing plate 51 back and forth to move reciprocatingly along the limiting slide 54, so that the bristle fixing plate 51 drives the hard bristles 52 to clean the loose parts of the mortar layer on the wall, and at the same time, the bristle fixing plate 51 as a whole will move up and down synchronously with the friction driving wheel group 7.

[0039] like Figure 3 , Figure 5 and Figure 6As shown, the bristle fixing plate 51 is in conflict with the limiting support frame 3 and the positioning support frame 1, the hard bristles 52 are located on the side of the bristle fixing plate 51 away from the limiting support frame 3, the limiting slide 54 corresponds to the position of the limiting slider 4, and the limiting slider 4 is slidably connected inside the limiting slide 54, the limiting slide 54 and the limiting slider 4 are distributed on both sides of the friction drive wheel group 7, the fixing seat 55 is located on both sides of the limiting slide 54, the friction wheel of the friction drive wheel group 7 is movably connected inside the roller placement opening 53, the width value of the roller placement opening 53 is greater than the width value of the friction wheel of the friction drive wheel group 7, and the friction wheel of the friction drive wheel group 7 does not contact the bristle fixing plate 51, and the bristle fixing plate 51 maintains a parallel state with the positioning support frame 1 and the limiting support frame 3 through the limiting slide 54 and the limiting slider 4.

[0040] The above scheme is adopted: by setting the bristle fixing plate 51 and the hard bristles 52, so as to facilitate the cleaning of the wall surface, the limit slide 54 slides horizontally under the support of the limit slide block 4, thereby driving the bristle fixing plate 51 and the hard bristles 52 to move left and right, so as to ensure that the wall cleaning effect reaches the requirements, and by setting the friction wheel of the friction driving wheel group 7 inside the roller placement opening 53, when cleaning the corners of the wall, the friction driving wheel group 7 will not block the hard bristles 52, so as to avoid cleaning the missed positions first, and at the same time, the width of the roller placement opening 53 is set to be larger than the friction driving wheel group 7, so that the bristle fixing plate 51 will not contact the friction driving wheel group 7 when moving left and right, so as to avoid the friction driving wheel group 7 from getting stuck;

[0041] By setting a limiting slide 54 and a limiting slider 4, the bristle fixing plate 51 is limited by the limiting slide 54 and the limiting slider 4, and always keeps parallel with the positioning support frame 1 and the limiting support frame 3, so that the bristle fixing plate 51 cannot rotate autonomously, thereby preventing the bristle fixing plate 51 from deviating to one side, causing the hard bristles 52 to tilt toward one side, resulting in excessive wear on the same side.

[0042] like Figures 4 to 10 As shown, the transmission assembly 8 includes a worm gear 81 and a turbine 85. Both ends of the worm gear 81 are fixedly connected to a turntable 82. The side of the turntable 82 away from each other is fixedly connected to a transmission connecting rod 83. The middle part of the transmission connecting rod 83 is rotatably connected to a transmission push-pull rod 84.

[0043] The above scheme is adopted: by setting up a transmission assembly 8, the turbine 85 drives the worm rod 81 to rotate, so that the worm rod 81 drives the transmission push-pull rod 84 to move through the turntable 82 and the transmission connecting rod 83, and the transmission push-pull rod 84 pulls the bristle fixing plate 51 back and forth through the fixed seat 55 to slide left and right, so that the friction driving wheel group 7 drives the bristle fixing plate 51 to move up and down, and the bristle fixing plate 51 itself will also move left and right to clean the wall.

[0044] like Figures 4 to 8As shown, the worm 81 is rotatably connected to the limit support frame 3 through a pair of support rods, and the worm 81 and the friction drive wheel group 7 are cross-distributed, the turbine 85 is fixedly connected to the middle part of the friction drive wheel group 7, the thread in the middle part of the worm 81 is meshed with the turbine 85, both ends of the worm 81 penetrate the limit support frame 3 and extend to the outside of the limit support frame 3, the turntable 82 is located on the outside of the limit support frame 3, a pair of transmission connecting rods 83 are positioned correspondingly, and the transmission connecting rods 83 are tangent to the sides of the turntable 82, and the transmission push-pull rod 84 is rotatably connected to the fixed seat 55 at one end away from the transmission connecting rod 83. When the worm 81 is driven to rotate by the friction drive wheel group 7 through the turbine 85, the turntable 82 drives the transmission connecting rod 83 to rotate, so that the transmission push-pull rod 84 pulls the bristle fixing plate 51 back and forth through the fixed seat 55 to reciprocate along the friction drive wheel group 7.

[0045] The above scheme is adopted: by setting the worm rod 81 and the turbine 85, and setting the worm rod 81 and the friction drive wheel group 7 to be cross-distributed, it is convenient for the thread in the middle of the worm rod 81 to mesh with the turbine 85, so that the turbine 85 can be driven to rotate by the friction drive wheel group 7 to drive the worm rod 81 to rotate synchronously, and the setting of the rotating disk 82 and the transmission connecting rod 83 can convert the rotational force of the worm rod 81 into thrust and pulling force for horizontal movement through the transmission push-pull rod 84, so as to drive the bristle fixing plate 51 to move;

[0046] When the friction drive wheel group 7 rotates and drives the worm rod 81 to rotate through the turbine 85, the worm rod 81 drives the worm rods 81 at both ends to rotate, so that the turntable 82 drives the transmission push-pull rod 84 to move through the transmission connecting rod 83, and the transmission push-pull rod 84 drives the bristle fixing plate 51 to reciprocate along the friction drive wheel group 7.

[0047] like Figure 2 , Figure 5 and Figure 8 As shown, the water spray assembly 9 includes a pair of water pipes 91, the top of the pair of water pipes 91 is fixedly connected with a water inlet pipe 92, one end of the water pipe 91 is rotatably connected with a row of nozzles 93, a section of the row of nozzles 93 located inside the water pipe 91 is provided with a water inlet 94, and the side of the pair of water pipes 91 close to each other is slidably connected with a sliding sealing rod 95;

[0048] The water supply pipe 91 is located on the inner side of the positioning support frame 1 and is fixedly connected to the positioning support frame 1. The water inlet pipe 92 is externally connected to a manual pressure pot. The row type nozzle 93 is fixedly connected to the positioning support frame 1. The water inlet 94 has the same length as the bristle fixing plate 51. The sliding sealing rod 95 is fixedly connected to the bristle fixing plate 51. A section of the sliding sealing rod 95 located inside the row type nozzle 93 is provided with a leakage groove.

[0049] The above scheme is adopted: by setting up a water spraying assembly 9, the water inside the external pressure kettle is guided to the inside of the water supply pipe 91 by the water inlet pipe 92. When the bristle fixing plate 51 moves left and right, the bristle fixing plate 51 will drive the sliding sealing rod 95 to move synchronously, so that the water is transported to the row type nozzle 93, and enters the inside of the row type nozzle 93 through the water inlet 94 to spray water on the wall. By setting the sliding sealing rod 95 and the groove opened on the sliding sealing rod 95, the inside of the water supply pipe 91 will connect the water inlet pipe 92 with the row type nozzle 93 after the sliding sealing rod 95 moves, so that the wall can be sprayed with water while cleaning the wall, which can save the water spraying steps and play a dust reduction role.

[0050] The working principle and use process of the present invention are as follows: when in use, a long pole with a sufficient length is connected to the flip connection frame 2, and the hard bristles 52 are facing the wall. If the upper side of the wall is cleaned first, the support wheel 6 can be facing the lower side, so that the support wheel 6 will not collide with the ceiling when the friction drive wheel group 7 moves to the top of the wall, so as to avoid the support wheel 6 blocking the cleaning of the wall, and then the friction drive wheel group 7 is pushed to move up and down, so that the friction drive wheel group 7 drives the bristle fixing plate 51 to slide up and down to clean the wall;

[0051] While the friction drive wheel set 7 moves up and down along the wall, the friction drive wheel set 7 will rotate with the friction of the wall, so that the friction drive wheel set 7 will synchronously drive the turbine 85 to rotate, and the turbine 85 drives the vortex rod 81 to rotate, so that the vortex rod 81 can drive the vortex rods 81 at both ends to rotate, thereby driving the transmission connecting rod 83 to rotate, so that the transmission connecting rod 83 continuously pushes and pulls the transmission push-pull rod 84 to move, and at this time the transmission push-pull rod 84 will drive the bristle fixing plate 51 to move, and at the same time the bristle fixing plate 51 will drive the sliding sealing rod 95 to move synchronously, so that water is transported to the row type nozzle 93, spraying water on the wall, so that the bristle fixing plate 51 cleans the wall with the hard bristles 52, and when the upper side of the wall is cleaned, the friction drive wheel set 7 and the support wheel 6 can be turned around and moved downward from the middle to clean the lower half of the wall.
