[0027] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0028] Embodiment 1
[0029] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, a tower rust removal device, which includes an installation shell 1. A connection groove 10 is provided on one side of the installation shell 1. A switch is arranged inside the connection groove 10. By setting the switch inside the connection groove 10, when a user grasps the installation shell 1, they will not directly accidentally press the switch. A battery is arranged inside the installation shell 1. A grinding component 6 is provided in front of the installation shell 1. A motor 21 is arranged inside the installation shell 1. The switch is electrically connected to the motor 21 through the battery. The motor 21 is started through the switch inside the connection groove 10 to drive the grinding component 6 to rotate, so as to perform grinding rust removal treatment on the surface of the tower;
[0030] An installation column 22 is fixedly provided at the front end of the installation shell 1. The output end of the motor 21 passes through the installation shell 1 and the installation column 22 and extends forward. A connection component 3 is arranged outside the installation column 22. A cooling component 8 is arranged at the rear end of the connection component 3. The cooling component 8 is used to cool the grinding component 6 and the surface of the tower being ground. A fixing component 7 is arranged inside the grinding component 6. The fixing component 7 is used to fix the grinding component 6 to the output end of the motor 21. A guiding component 4 is arranged outside the grinding component 6. An installation component 5 is arranged at the rear end of the connection component 3. The installation component 5 is used to disassemble the connection component 3 and the guiding component 4 to facilitate the replacement of the grinding component 6;
[0031] The connection component 3 includes two symmetrically arranged connection half-rings 31. The two connection half-rings 31 are spliced together to form a ring. The installation column 22 is located inside this ring. The two connection half-rings 31 are respectively located at the top and bottom of the installation column 22. A protective half-ring 32 is fixedly provided at the front end of the connection half-ring 31. The two protective half-rings 32 are symmetrically arranged to form a ring, which is spliced and communicated with the ring formed by the two connection half-rings 31;
[0032] While water adheres to the surface of the grinding component 6 through the cooling component 8, the grinding component 6 rotates at a high speed. At this time, the water on the surface of the grinding component 6 will be thrown out due to centrifugal force. At this time, it is blocked and protected by the protective half-ring 32. A communication hole 33 is provided on the connection half-ring 31 located below. The cooling component 8 includes a water spray head 81 fixed inside the communication hole 33. The nozzle of the water spray head 81 faces the front-end grinding component 6. A connection pipe 82 is fixedly provided at the rear end of the water spray head 81. The connection pipe 82 is used to connect with a container filled with water or directly connect with a faucet or a water outlet. The liquid is pumped into the water spray head 81 through a water pump, and the water is sprayed onto the surface of the grinding component 6 through the nozzle at the front end of the water spray head 81. The liquid sprayed out by the connection pipe 82 cools the rear end of the grinding component 6, and cooperates with the connection component 3 and the guiding component 4 to cover the liquid on the front end of the grinding component 6 and the surface of the tower being ground for rust removal, so as to increase the cooling effect;
[0033] By attaching water to the surfaces of the grinding assembly 6 and the tower, while cooling the grinding assembly 6 and the tower surface to prevent thermal damage, the water can also wash away the rust slag and metal debris generated by grinding, prevent a large amount of debris dust from being generated during grinding, inhibit the floating of dust, and provide a certain degree of protection for the staff;
[0034] Wetting the surfaces of the grinding assembly 6 and the tower can reduce the friction coefficient between the grinding assembly 6 and the tower surface. After the water penetrates into the microcracks of the rust layer, it can weaken the bonding force of the rusty surface, making the loose rust easier to peel off, increasing the grinding speed, providing the effect of lubrication and resistance reduction, and after cooling, the surface of the grinding assembly 6 can always be in a suitable state, which can avoid the problem that the surface of the grinding assembly 6 becomes hot after grinding and it is easy for the staff to accidentally touch it and get scalded.
[0035] Further, as Figure 1 、 Figure 2 and Figure 3 shown, the grinding assembly 6 includes a grinding disc 61. The front end of the grinding disc 61 is provided with grinding textures, and the grinding textures include but are not limited to staggered diamond grid textures. An installation groove 62 is opened at the front end of the grinding disc 61. The grinding disc 61 is located inside the protective semi-ring 32. A plurality of guide holes 63 opened on the grinding disc 61 are provided on the circumferential side of the installation groove 62. The guide holes 63 communicate the front end and the rear end of the grinding disc 61. When the connecting pipe 82 sprays water to cover the rear end of the grinding disc 61, part of the water flows through the guide holes 63 and extends to the front end of the grinding disc 61, and contacts the front end of the grinding disc 61 and the tower surface in front of the grinding disc 61 in cooperation with the rotation of the grinding disc 61. A chamfer 64 is opened at the front edge of the front end of the guide hole 63. The water inside the guide hole 63 is guided by the chamfer 64 to cover the surface of the grinding disc 61, making the water flow cover more evenly and increasing the contact area;
[0036] When the grinding disc 61 rotates, it can increase the contact area with the water flow through the guide holes 63 and the chamfer 64, and cooperate with the rotation to make the airflow collide with the surfaces of the guide holes 63 and the chamfer 64 for heat exchange and cooling.
[0037] Further, as Figure 2 and Figure 3 shown, the grinding disc 61 is specifically in the shape of being narrower at the front and wider at the rear, close to a flat cone shape. The tower is polished and rust-removed through the narrower front surface. Through the shape of the grinding disc 61 being narrower at the front and wider at the rear, and in cooperation with the inclined surface on the circumferential side, when the water at the front end is thrown outwards by the high-speed rotation of the grinding disc 61, the water flow is guided backwards in cooperation with the inclined surface and is thrown out through the wider rear part. It is blocked by the inside of the guiding semi-ring 41 and the protective semi-ring 32 to prevent water from splashing.
[0038] Embodiment 2
[0039] The tower rust removal device provided in Embodiment 1 is further optimized. Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the guiding assembly 4 includes two guiding half-rings 41, which are respectively fixedly connected to the front end of the protective half-ring 32. The two guiding half-rings 41 are symmetrically arranged to form a ring, which is butt-connected and communicated with the ring formed by the two protective half-rings 32. The two guiding half-rings 41 are inclined, and the inclination makes the ring formed by the two guiding half-rings 41 have a shape that is narrow at the front and wide at the back;
[0040] The inclination of the guiding half-ring 41 can wrap and be located on the wider side of the circumferential side of the grinding disc 61, cooperate with the protective half-ring 32 to enclose the grinding disc 61, and only expose the front end part of the grinding disc 61 for grinding, improving the safety during use. And when the grinding disc 61 throws water onto the protective half-ring 32 or when the water spray head 81 sprays water into the protective half-ring 32, part of the water can be guided by the inclined surface inside the guiding half-ring 41 to cover and contact the side surface of the grinding disc 61, increasing the comprehensiveness of water coverage, improving the cooling effect while enhancing the utilization rate of water, and the dust and rust slag located inside the protective half-ring 32 can be washed out to the outside through the cooperation of the water flow and the guiding of the fixed half-ring 42, cleaning its interior.
[0041] Further, as Figure 2 and Figure 3 shown, a fixed half-ring 42 is fixedly provided at the front end of the guiding half-ring 41. The two fixed half-rings 42 are symmetrically arranged to form a ring, which is butt-connected and communicated with the ring formed by the two guiding half-rings 41. The fixed half-ring 42 is inclined and the inclination direction is opposite to that of the guiding half-ring 41, so that the fixed half-ring 42 has a shape that is wide at the front and narrow at the back. The wider part of the fixed half-ring 42 can, to a certain extent, prevent the staff's hand from moving forward continuously during use, preventing the staff's hand from contacting the grinding disc 61.
[0042] Further, as Figure 2 , Figure 3 and Figure 4As shown in the figure, the installation component 5 includes two installation half-rings 52. The two installation half-rings 52 are symmetrically arranged to form a ring. The two installation half-rings 52 are respectively fixed to the rear ends of the two connection half-rings 31. The installation half-ring 52 is detachably connected to the installation column 22. Bolts or screws are provided on the circumferential side of the outer part of the installation half-ring 52. The end of the bolt or screw passes through the installation half-ring 52 and inserts a certain distance on the installation column 22 and is threadedly connected. Installation plates 51 are fixedly provided on both sides of the installation half-ring 52. Among the installation plates 51 on both sides of the upper and lower installation half-rings 52, the two installation plates 51 on the same side are in contact with each other and are detachably connected. A number of bolts or screws are provided at the top of the installation plate 51 located above. The end of the bolt or screw passes through the two installation plates 51 on the same side and is threadedly connected, so as to achieve detachable connection. The installation plate 51 is fixedly connected to the connection half-ring 31 and the protection half-ring 32.
[0043] Furthermore, as Figure 1 , Figure 2 and Figure 3 shown, the fixing component 7 includes a fixing plate 71 fixed to the output end of the motor 21. A fixing cushion plate 72 is provided inside the installation groove 62. The fixing cushion plate 72 is used to prevent the relatively large head of the bolt from directly contacting and squeezing the grinding disc 61, resulting in wear of the holes on the grinding disc 61. Through the fixing cushion plate 72, the stress area in contact with the grinding disc 61 can be increased, and the stability and durability can be increased. The fixing plate 71 is located at the rear end of the grinding disc 61. The fixing plate 71 is detachably connected to the fixing cushion plate 72. The end of a number of bolts passes through the fixing cushion plate 72, the grinding disc 61 and the fixing plate 71 and is threadedly connected, so as to clamp the grinding disc 61 in the middle to achieve detachable connection. The grinding disc 61 can be separated and removed by removing the bolts.
[0044] Embodiment 3
[0045] Further optimize the tower rust removal device provided in Embodiment 1 and Embodiment 2. As Figure 1 and Figure 2 shown, a handle 91 is fixedly provided at the rear end of the installation shell 1. The handle 91 is used to enable the user to have an additional position to hold, making it more convenient to hold the installation shell 1 and facilitating taking and applying force. A protective pad 92 is fixedly provided at the rear end of the handle 91. The protective pad 92 is made of, but not limited to, rubber. The protective pad 92 is used to prevent the end of the handle 91 from hitting the user's head or chest during use. The protective pad 92 provides buffering to relieve the impact force during collision.
[0046] The use process of the tower rust removal device provided by the present utility model is as follows:
[0047] When it is necessary to grind and remove rust on the surface of the tower, connect the connecting pipe 82 to a container filled with water, start the motor 21 through the switch to drive the grinding disc 61 to rotate, then contact the front end of the grinding disc 61 with the position of the tower that needs rust removal, and remove the surface rust by the grinding texture at the front end of the grinding disc 61 in cooperation with the high-speed rotation. Then start the water pump to pump the liquid into the water spray head 81, and spray the water onto the surface of the grinding disc 61 through the nozzle at the front end of the water spray head 81 to cool the grinding disc 61;
[0048] When the water spray head 81 sprays water to the rear end of the grinding disc 61, the water flow extends to the front end of the grinding disc 61 through the guiding hole 63, and contacts the front end of the grinding disc 61 and the surface of the tower in front of the grinding disc 61 in cooperation with the rotation of the grinding disc 61. The water inside the guiding hole 63 is guided by the chamfer 64 to cover the surface of the front end of the grinding disc 61, making the water flow coverage more uniform and increasing the contact area. At the same time, it cools the tower and the grinding assembly 6; Then part of the water flow follows the inclined angle on the side of the grinding disc 61 and is thrown out through the wider part behind the grinding disc 61 in cooperation with the centrifugal force generated by the rotation of the grinding disc 61, and converges with part of the water flow located between the grinding disc 61 and the connecting half-ring 31. It collides with the protective half-ring 32 in cooperation with the centrifugal force generated by the rotation of the grinding disc 61 and flows forward, and is guided to the vicinity of the front end of the grinding disc 61 and the surface of the tower at the front end of the grinding disc 61 through the inclined surface of the guiding half-ring 41, improving the utilization rate of water and preventing water splashing;
[0049] When it is necessary to disassemble the connecting assembly 3, the guiding assembly 4 and the mounting assembly 5 from the mounting column 22, remove the bolts threaded on the two mounting plates 51 on the same side, and remove the bolts connecting the mounting half-ring 52 and the mounting column 22, so that the bolts are separated from the mounting column 22, so that the connecting half-rings 31, the protective half-rings 32, the guiding half-rings 41 and the fixing half-rings 42 above and below can be separated and removed from the mounting column 22.
