Description

Technical Field

[0001] This utility model relates to the field of magnetic cleaning robot technology, and in particular to a settling tank cleaning robot. Background Technology

[0002] In the smelting of iron ore, gold ore, and other ores, large settling tanks are required. During long-term settling, the ore hardens on the metal walls of the equipment, leaving behind a large amount of slag. This slag not only affects the efficiency of smelting but also wastes resources. To improve production efficiency, workers need to clean the residue from the walls. However, traditional cleaning methods primarily involve manual high-level operations using hammering and other methods. Especially when the slag buildup on the inner walls of the settling tank bottom is too thick, considerable force is required to pry it off, resulting in high labor intensity. Furthermore, the vibrations generated during manual cleaning can cause the slag on the walls to loosen, fall in chunks, or collapse, leading to safety accidents and posing serious safety hazards. Moreover, hammering and other methods can damage the metal walls of the equipment, and the strong vibrations can affect the sealing of certain equipment pipe connections. Therefore, to solve these technical problems and address the issue of slag buildup on the inner walls of the settling tank, a new settling tank cleaning robot needs to be designed to replace manual labor.

[0014] Furthermore, the magnetic attraction portion is distributed on the inner side of the two drive wheels at the bottom of the walking machine body and in the middle of the bottom surface of the hinge seat.

[0015] The beneficial effects of this utility model are:

[0016] 1) This utility model uses a magnetic suction unit to attach the walking machine body to the wall of the settling tank. Two drive wheels drive the walking machine body, bringing the support body closer to the slag. The rotating motion of several grinding blades forms a grinding and cleaning surface that continuously contacts and grinds the deposited slag, causing it to detach from the inner wall of the settling tank, thus achieving a cleaning effect. Since the chain cleaning mechanism needs to rotate continuously to form the grinding and cleaning surface, it must maintain a certain distance from the tank wall to avoid contact with the tank wall and damage to the settling tank. The trough, due to its inherent limitations, leaves some slag residue on the trough walls that cannot be cleaned by the chain cleaning mechanism. Therefore, this application adds a water jet cleaning mechanism. The water jet nozzles are angled downwards and rotate back and forth along the support, using water jets to create a fan-shaped area to flush away the slag adhering to the trough walls. This not only supplements the areas that the chain cleaning mechanism cannot clean, but also uses the water mist to settle dust generated during slag grinding. The water spray also cools the grinding tools of the chain cleaning mechanism, achieving multiple benefits. This invention can efficiently and safely clean the material adhering to the inner walls of the trough, solving the problem of internal wall scaling, significantly improving cleaning efficiency, and reducing the labor intensity of workers.

[0017] 2) When the cleaning drive motor drives multiple first cleaning sprockets to rotate, thereby driving multiple first cleaning chains to drive several grinding tools to rotate along the periphery of the chain mounting base to form a grinding and cleaning surface, the multiple first cleaning chains not only provide strong rotational cutting force, but also provide strong support force for each grinding tool. Considering that the first cleaning chain is only supported by the first cleaning sprockets at both ends, and the middle of the first cleaning chain cannot apply force to press against the slag, and may even break or lose teeth under the influence of reaction force, a support plate is provided on one side of the front end of each of the two mounting plates. The plane of the support plate is flush with the outer periphery of the first cleaning chain. When the grinding tool grinds and cleans the slag, its back can be kept in a plane by the support force of the support plate, so as not to cause the first cleaning chain to be concave, affecting the cleaning effect and the service life of the first cleaning chain.

[0018] 3) A second chain cleaning mechanism is also provided between the two chain mounting seats. The second chain cleaning mechanism shares a drive shaft with the chain cleaning mechanism to save manufacturing costs and ensure the coaxiality of the drive shaft. More importantly, the second chain cleaning mechanism can fill the gap between the two chain mounting seats and increase the overall area of ​​the grinding and cleaning surface.

[0019] 4) The grinding spikes and trapezoidal connecting blocks are connected by bolts, and can be replaced in time if damaged to ensure the grinding and cleaning effect.

[0020] 5) The articulated seat can float and adjust with the changes in road surface unevenness, so that at least one of the two driven wheels will always be in contact with the road surface to support the walking machine. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Reference Figures 1 to 6As shown, a settling tank cleaning robot includes a walking body 1, a support body 2, a chain cleaning mechanism 3, and a water jet cleaning mechanism 4.

[0034] The walking machine body 1 has a drive wheel 11 on each side of its front end, each driven independently by a single motor. When the two drive wheels 11 rotate forward simultaneously, the walking machine body 1 moves forward; when they rotate in reverse simultaneously, the walking machine body 1 moves backward; and when they rotate in opposite directions, the walking machine body 1 turns left or right. To maintain balance, the walking machine body 1 has a driven wheel 12 on each side of its rear end. A hinge seat 13 is located at the bottom of the rear end of the walking machine body 1. The hinge seat 13 is arranged along the width of the walking machine body 1, and its top surface is hinged to the center of the bottom of the rear end of the walking machine body 1. The two ends of the top surface of the hinge seat 13 are connected to the bottom of the rear end of the walking machine body 1 by a spring 14. The two driven wheels 12 are fixedly connected to the bottom sides of the hinge seat 13. The hinge seat 13 can float and adjust according to the unevenness of the road surface, so that at least one of the two driven wheels 12 is always in contact with the road surface to support the walking machine body 1. The bottom of the walking body 1 is provided with a magnetic suction part 15, which is distributed on the inner side of the two driving wheels 12 and the middle of the bottom surface of the hinge seat 13.

[0035] The support frame 2 is fixedly connected to the top front end of the walking machine body 1, and one end of the support frame 2 extends to the outside of the front end of the walking machine body 1. Specifically, the support frame 2 includes a fixing frame 21 and a mounting frame 22; one end of the fixing frame 21 is fixedly connected to the middle of the mounting frame 22; the other end of the fixing frame 21 is fixedly connected to the top of the walking machine body 1.

[0036] The chain cleaning mechanism 3 is mounted on the mounting frame 22. The chain cleaning mechanism 3 is equipped with several grinding blades 31 that rotate around the front circumference of the support body 2. The grinding blades 31 rotate around the mounting frame 22, forming a grinding and cleaning surface at the front end of the support body 2. When the walking machine 1 is attracted to the wall of the settling tank by the magnetic suction part 15, the two drive wheels 11 drive the walking machine 1 to move and move the support body 2 closer to the slag. The grinding and cleaning surface formed by the rotation of the grinding blades 31 contacts and continuously grinds the deposited slag, thereby causing the deposited slag to fall off from the inner wall of the settling tank, achieving the effect of cleaning the settling tank.

[0037] Since the chain cleaning mechanism 3 needs to rotate continuously to form a polishing and cleaning surface, it needs to maintain a certain distance from the tank wall to avoid contact with the tank wall and damage to the settling tank. As a result, some slag remains on the tank wall and cannot be cleaned by the chain cleaning mechanism 3. Therefore, this application adds a water jet cleaning mechanism 4 to make up for the cleaning space between the chain cleaning mechanism 3 and the tank wall. The water jet cleaning mechanism 4 is installed on the fixed frame 21 and is located between the mounting frame 22 and the walking body 1. The water jet cleaning mechanism 4 is provided with a water jet nozzle 41 located below the chain cleaning mechanism 3. The water jet nozzle 41 rotates back and forth along the support body 2. One end of the water jet nozzle 41 is connected to an external high-pressure water supply pipe. The water jet nozzle 41 sprays downwards at an angle. The water jet nozzle 41 rotates back and forth along the support body 2, using water force to flush and clean the slag adhering to the tank wall in a fan-shaped area. This not only supplements the areas that the chain cleaning mechanism 3 cannot clean, but also the water mist splashed up by the water flow can be used to settle the dust generated during the grinding of slag. The water spray and mist can also cool down the grinding tools 31 of the chain cleaning mechanism 3, achieving multiple benefits in one fell swoop.

[0038] In this embodiment, the mounting frame 22 includes two chain mounting seats 221 and a connecting plate 222. Each chain mounting seat 221 is vertically distributed, and the two chain mounting seats 221 are symmetrically distributed about the vertical center line of the connecting plate 222. The two sides of the connecting plate 222 are respectively fixedly connected to one of the chain mounting seats 221. The chain cleaning mechanism 3 includes several grinding tools 31, several first cleaning chains 32, several first cleaning sprockets 33, a drive shaft 34, two driven shafts 35, and a cleaning drive motor 36. The drive shaft 34 is arranged horizontally, and its two ends are rotatably connected to the top of one of the chain mounting seats 221. Each driven shaft 35 is rotatably connected to the bottom of one of the chain mounting seats 221. Each chain mounting seat 221 has several first cleaning sprockets 33 at its top and bottom. The first cleaning sprockets 33 at the top are mounted on the drive shaft, and the first cleaning sprockets 33 at the bottom are mounted on the drive shaft. A plurality of first cleaning sprockets 33 are mounted on corresponding driven shafts 35. The number and position of the cleaning sprockets 32 at the upper and lower parts of the same chain mounting base 221 are one-to-one. Each first cleaning chain 32 is wound around the two corresponding cleaning sprockets 33 and meshed with them. A plurality of horizontally arranged and spaced grinding tools 31 are provided on the outer periphery of all the first cleaning chains 32 of the same chain mounting base 221. The plurality of grinding tools 31 surround the outer periphery of the chain mounting base 221. One side of each grinding tool 31 is fixedly connected to the two outermost first cleaning chains 32 of the same chain mounting base 221. The other side of each grinding tool 31 is fixedly connected to a plurality of spaced grinding spikes 311. The cleaning drive motor 36 is fixedly connected to the fixed frame 21. The cleaning drive motor 36 is connected to the drive shaft 34 through a drive chain 37.Specifically, the chain mounting base 221 includes two parallel and spaced mounting plates 2211, which are fixedly connected by a plurality of connecting posts 2212. The connecting posts 222 are fixedly connected to the inner mounting plate 2211 of one of the chain mounting bases 221. A clearance hole is provided at the top of the inner mounting plate 2211 of the two chain mounting bases 221. Both ends of the drive shaft 34 pass through a corresponding clearance hole and are rotatably connected to the top of the outer mounting plate 2211 of the two chain mounting bases 221. Both ends of each driven shaft 25 are rotatably connected to the same chain mounting base 221. The bottom of the two mounting plates 2211 on 1; the two mounting plates 2211 and several connecting posts 2212 are assembled into a hollow chain mounting base 221, so that the first cleaning sprocket can be installed in the chain mounting base 221, so that the first cleaning chain 32 is located between the corresponding two mounting plates 2211. When the cleaning drive motor 36 drives the multiple first cleaning sprockets 32 to rotate, thereby driving the multiple first cleaning chains 32 to drive the multiple grinding tools 31 to rotate along the circumference of the chain mounting base 221 to form a grinding and cleaning surface, the multiple first cleaning chains not only provide a strong rotational cutting force, but also provide a strong support force for each grinding tool. Considering that the first cleaning chain 32 is only supported by the first cleaning sprockets 32 at both ends, and the middle of the first cleaning chain 32 cannot apply force to press against the slag, and may even break or lose teeth under the influence of reaction force, a support plate 2213 is provided on one side of the front end of each of the two mounting plates 2211. The plane of the support plate 2213 is flush with the outer periphery of the first cleaning chain 32. When the grinding tool 31 grinds and cleans the slag, its back side can be kept in a plane by the support force of the support plate 2213, so as not to cause the first cleaning chain 32 to be concave, which would affect the cleaning effect and the service life of the first cleaning chain.

[0039] A second chain cleaning mechanism 5 is also provided between the two chain mounting seats 221. The structure of the second chain cleaning mechanism 5 can refer to the chain cleaning mechanism 3 described above. However, the second chain cleaning mechanism 5 shares a drive shaft 34 with the chain cleaning mechanism 3 described above, in order to save manufacturing costs and ensure the coaxiality of the drive shaft. More importantly, the second chain cleaning mechanism 5 can fill the gap between the two chain mounting seats 221, increasing the overall area of ​​the polishing and cleaning surface. The specific structure and connection method are as follows: The second chain cleaning mechanism 5 further includes several second cleaning chains 51, several second cleaning sprockets 52, several grinding tools 31, a second driven shaft 53, and two second mounting plates 54.

All the second cleaning chains 51 have a number of horizontally arranged and spaced-apart grinding tools 31 on their outer periphery. The grinding tools 31 surround the outer periphery of the second mounting plate 54. One side of each grinding tool 31 is fixedly connected to the two outermost second cleaning chains 51. The other side of each grinding tool 31 is fixedly connected with a number of spaced-apart grinding spikes 311. The front end of the second mounting plate 54 has a support plate that is flush with the periphery of the second cleaning chains 51.

The vertical end of the L-shaped connecting ear is welded or riveted to the first cleaning chain, and the horizontal end of the L-shaped connecting ear is fixedly connected to one side of the fixing strip by bolts. The grinding tool 31 is made entirely of alloy steel, with diamond patches applied to the surface of the grinding tip to ensure sufficient hardness and strength during cutting. Even if the diamond patches wear off, the alloy steel blade can continue cutting, greatly extending the tool's lifespan. Furthermore, the grinding tip 311 is bolted to a trapezoidal connecting block 312. During installation, the triangular structure is used to fix the orientation of the grinding tip 311. When the grinding tip 311 is damaged, it can be replaced in time to ensure a clean grinding effect.

[0041] The fixed frame 21 has two outwardly extending connecting arms 211 fixedly connected to its two sides. The two connecting arms 211 are located at the front ends of the two drive wheels 11.

The rotating shaft of the swing drive motor 44 performs a certain angle of forward and reverse rotation cycle to drive the Z-shaped water pipe 42 to swing at a certain angle, thereby making the spray direction of the water jet nozzle 41 form a fan-shaped area.

[0043] The top of the walking body 1 is also equipped with two hooks, which facilitates the movement of the entire robot to the wall of the settling tank for adsorption and fixation by hoisting.
