Description

Technical Field

[0001] This invention relates to the technical field of anti-corrosion lining spraying equipment, and more particularly to an anti-corrosion lining spraying equipment based on the processing of chemical anti-corrosion tanks. Background Technology

[0002] In the production and storage systems of the chemical industry, corrosion-resistant chemical tanks are core infrastructure for ensuring the safe storage of corrosive media (such as strong acids, strong alkalis, and organic solvents). The integrity and uniformity of the anti-corrosion coating on the inner wall directly determine the service life of the tank, the safety of the stored media, and its purity. To achieve long-term corrosion protection, the industry commonly adopts a process of spraying high-performance anti-corrosion linings (such as epoxy resin, polytetrafluoroethylene, and polyurethane) onto the inner wall of the tank. This process forms a continuous and dense coating that isolates the corrosive media from contact with the metal substrate, and has become a core step in the manufacturing of corrosion-resistant chemical tanks.

[0003] As the chemical industry develops towards large-scale and refined production, the structural design of chemical corrosion-resistant tanks has become increasingly diversified. In addition to the conventional cylindrical tank body, to adapt to the layout of inlet and outlet pipelines, enhance the structural stability of the tank body, and meet the requirements of media flow characteristics, the two ends of corrosion-resistant tanks are generally designed as frustum-shaped arc surfaces. These frustum-shaped arc surfaces not only have complex curvature changes, but also have irregular transition areas at the junction of the arc surface with the cylindrical section of the tank body and the flange interface. The quality of the anti-corrosion coating on its surface is particularly critical.

[0004] Existing equipment often uses nozzles installed at a fixed angle, covering a fixed area. The nozzle movement trajectory relies on a preset fixed program or simple mechanical limit control, lacking a corresponding spraying function for the actual shape of the frustum-shaped arc surface. Due to the dimensional deviation of the frustum-shaped arc surface during the processing of the anti-corrosion tank, when the preset trajectory cannot accurately match the actual arc surface contour of each anti-corrosion tank, the dwell time of the device in this area needs to be manually controlled. The operator's hand stability, brushing force, and experience affect the spraying area, which can easily lead to uneven coating thickness and even reduced adhesion. Summary of the Invention

[0005] In view of the problems in existing technology, such as the need for manual control of the dwell time of the device in the curved area, and the influence of the operator's hand stability, brushing force and experience, resulting in uneven coating thickness in the sprayed area, a corrosion-resistant lining spraying equipment based on the processing of chemical corrosion-resistant tanks is proposed.

[0006] This application provides a corrosion-resistant lining spraying device based on the processing of chemical corrosion-resistant tanks. Its purpose is to ensure the coating effect without manual control when spraying the corrosion-resistant lining of the inner wall of the frustum-shaped structure at the end of the corrosion-resistant tank.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This invention discloses an anti-corrosion lining spraying equipment based on the processing of chemical anti-corrosion tanks.

[0043] Example 1, referring to Figure 1-7This is the first embodiment of the present invention, providing an anti-corrosion lining spraying device based on the processing of chemical anti-corrosion tanks. The device includes a main body 1, an electric lifting frame 2 positioned above the main body 1, and a first spraying mechanism and a second spraying mechanism driven by a servo waterproof motor 5. The servo waterproof motor 5 is connected to the piston rod of the electric lifting frame 2 via a motor frame body 6. A rotary transmission assembly 10 is provided between the first and second spraying mechanisms. The first spraying mechanism includes a reciprocating spraying assembly 8 and a reciprocating transmission assembly 9, both positioned above the main body 1. The first spraying mechanism is used to spray the tank end of the anti-corrosion tank. The second spraying mechanism includes a paint conveying body 3 and a tank wall spraying body 4, both positioned above the main body 1. The spraying mechanism is used to spray the tank wall of the anti-corrosion tank. A tank-end spraying platform 7 is located above the main body 1. A laser indicator 71 for positioning the tank end is fixedly installed on the tank-end spraying platform 7, and the tank-end spraying platform 7 is connected to the rotary transmission assembly 10 via a synchronous rotating shaft 72. The reciprocating spraying assembly 8 includes a tank-end spraying pipe 81 movably mounted on the main body 1, a liquid supply rigid pipe 82 fixedly installed on the end of the tank-end spraying pipe 81 near the electric lifting frame 2, a tank-end nozzle 83 rotatably connected to the end of the tank-end spraying pipe 81 away from the liquid supply rigid pipe 82, and a tank-end control valve 84 located between the tank-end spraying pipe 81 and the liquid supply rigid pipe 82. The tank-end spraying pipe 81 is slidably connected to the tank-end spraying platform 7 via a horizontal displacement component 85. The reciprocating transmission assembly 9... The machine also includes a gear drive component 94 for driving the horizontal displacement component 85 to reciprocate. The main body 1 serves as the load-bearing foundation of the equipment, and its surface is treated with anti-corrosion coating to adapt to the working environment of anti-corrosion lining spraying. It is also equipped with a detachable counterweight to effectively prevent the device from tipping over. The electric lifting frame 2 achieves lifting action through electric drive, and is used to adjust the height position of the spraying mechanism to make it coincide with the axis of the tank, adapting to the processing requirements of anti-corrosion tanks of different specifications. The servo waterproof motor 5 has a waterproof sealing structure, which can operate stably in humid or paint-splashed environments and provide precise power output. The servo waterproof motor 5 can be fixed and supported by the motor frame body 6 to ensure its stable operation. The rotary transmission component 10 can realize power transmission and motion conversion, coordinating the two sets of mechanisms. The operation is synchronized. The first spraying mechanism is specifically designed for spraying the tank end of the anti-corrosion tank, including the curved surface and edges. The second spraying mechanism is responsible for spraying the tank wall, such as the transition area between the tank wall and the tank end of a cylindrical tank. The tank end spraying station 7 provides the installation foundation for the tank end spraying structure. The laser pointer 71 is used to quickly locate the position of the edge of the tank end to ensure spraying alignment accuracy. The tank end spraying station 7 can rotate synchronously with the rotary transmission assembly 10. The tank end spraying pipe 81 is used to transport paint to the tank end nozzle 83. The liquid supply rigid pipe 82 is responsible for connecting the paint supply pipeline to the tank end spraying pipe 81. After pressurization, the tank end nozzle 83 can rotate its internal turbine structure, thereby rotating and spraying the paint of the anti-corrosion lining to adapt to the complex curved surface of the tank end.The gear drive component 94 in the reciprocating transmission assembly 9 provides the driving force for the reciprocating sliding of the horizontal displacement component 85.

[0044] Specifically, firstly, the main body 1 is moved into the anti-corrosion tank to be sprayed, and a detachable counterweight is installed on the main body 1 to prevent tipping. The electric lifting frame 2 is then activated, and its height is adjusted electrically to align the first and second spraying mechanisms with the axis of the anti-corrosion tank, adapting to the current tank size. The laser indicator 71 on the tank-end spraying platform 7 is then activated to position the edge of the anti-corrosion tank end, ensuring precise alignment between the spraying platform 7 and the tank end, laying the foundation for subsequent tank-end spraying. The paint delivery body 3 is checked to ensure sufficient paint. Relevant control valves are opened, allowing the paint to be delivered through the liquid supply pipe 82 to the tank-end spraying pipe 81, and then sprayed out through the rotating nozzle 83. Finally, the servo waterproof motor 5 is activated, which, with the help of the motor... The main body 6 operates stably. The servo waterproof motor 5 outputs power to the rotary transmission component 10 and the reciprocating transmission component 9 respectively. After receiving the power, the rotary transmission component 10 realizes motion conversion, driving the can end spraying platform 7 to rotate synchronously. Under the action of power, the gear drive component 94 in the reciprocating transmission component 9 drives the horizontal displacement component 85 to slide back and forth along the can end spraying platform 7, thereby driving the can end spraying pipe 81 and the can end nozzle 83 to move back and forth synchronously. The turbine structure inside the can end nozzle 83 rotates after the paint is pressurized, spraying the paint out in a rotating manner. Combined with the rotation of the can end spraying platform 7 and the reciprocating movement of the can end nozzle 83, a comprehensive and uniform spraying of the can end arc surface and edge parts is achieved, thereby realizing automatic spraying of the can end arc surface and edge parts without additional manual intervention.

[0045] Reference Figure 5 and Figure 6 The horizontal displacement component 85 includes a guide rail 851 fixedly installed on the can end spraying station 7, a spraying base 852 disposed above the guide rail 851, and a rack 853 fixedly installed on one side of the spraying base 852. The can end spraying pipe 81 is slidably connected to the guide rail 851 through the spraying base 852, and the rack 853 and the can end spraying station 7 are mutually abutted. The guide rail 851 provides a stable sliding guide for the spraying base 852. The spraying base 852 is used to install the can end spraying pipe 81 and can move smoothly along the direction of the guide rail 851 with the spraying base 852. The abutment design can prevent structural interference between the rack 853 and the can end spraying station 7 when the rack moves.

[0046] Specifically, the gear drive component 94 in the reciprocating transmission assembly 9 drives the horizontal displacement component 85 to move. Since the guide rail 851 of the horizontal displacement component 85 is fixedly installed on the can end spraying platform 7 and provides stable sliding guidance for the spraying base 852, the spraying base 852 will move smoothly along the direction of the guide rail 851. The can end spraying pipe 81 is installed on the spraying base 852, so the can end spraying pipe 81 moves synchronously with the spraying base 852. At the same time, since the rack 853 is fixed on one side of the spraying base 852 and adopts a avoidance design with the can end spraying platform 7, the rack 853 will not cause structural interference with the can end spraying platform 7 when it moves with the spraying base 852. Thus, the can end spraying pipe 81 drives the can end nozzle 83 to move smoothly back and forth along the direction of the guide rail 851, providing a moving basis for uniform spraying of the can end.

[0047] Reference Figure 5 and Figure 7 The gear drive component 94 includes a screw 941 mounted on the can-end spraying platform 7, a threaded sleeve 942 mounted on the side of the can-end spraying platform 7 near the spraying base 852, and a gear 943 mounted on the threaded sleeve 942. The screw 941 is slidably connected to the can-end spraying platform 7 and is distributed to avoid the guide rail 851. The threaded sleeve 942 is rotatably connected to the side of the can-end spraying platform 7 near the rack 853 and is threadedly connected to the screw 941. The gear 943 is fixedly mounted on the threaded sleeve 942 and meshes with the rack 853. The screw 941 can slide axially to transmit linear power. The threaded sleeve 942 and the screw 941 cooperate to realize motion conversion. The gear 943 can maintain synchronous rotation through the threaded sleeve 942 and transmit rotational power through meshing with the rack 853.

[0048] Specifically, during the driving process of the horizontal displacement component 85, the screw 941 of the gear drive component 94 is first driven by external power to slide axially. Since the screw 941 is threadedly engaged with the threaded sleeve 942 rotatably connected to the spraying station 7 at the can end near the rack 853, the axial sliding of the screw 941 will drive the threaded sleeve 942 to rotate synchronously. Since the gear 943 is fixedly installed on the threaded sleeve 942, the rotation of the threaded sleeve 942 will drive the gear 943 to rotate synchronously. The gear 943 meshes with the rack 853 on the side of the spraying base 852 in the horizontal displacement component 85. Finally, the rotational power of the gear 943 is transmitted to the rack 853 through meshing, driving the rack 853 to move the spraying base 852 along the guide rail 851, realizing the conversion of motion from linear to rotation and back to linear and the transmission of power.

[0049] During operation, the main body 1 is first moved into the anti-corrosion tank to be sprayed. A detachable counterweight is installed on the main body 1 to prevent tipping. Then, the electric lifting frame 2 is activated, and its height is adjusted electrically to align the first and second spraying mechanisms with the tank's axis to fit the tank's specifications. Simultaneously, the laser indicator 71 on the tank-end spraying platform 7 is activated to locate the edge of the anti-corrosion tank, ensuring precise alignment between the spraying platform 7 and the tank end. Next, the paint delivery body 3 is checked to ensure sufficient paint. Relevant control valves are opened, allowing paint to be delivered to the tank-end spraying pipe 81 via the liquid supply hard pipe 82. Then, the servo waterproof motor 5 is started, operating stably with the help of the motor frame body 6. Its output power is transmitted to the rotary transmission component 10 and the reciprocating transmission component 9. The rotary transmission component 10 receives power and performs motion conversion, driving the tank-end spraying platform 7 to rotate synchronously. The gears in the reciprocating transmission component 9... Under the action of power, the drive component 94 first drives the screw 941 to slide axially. Since the screw 941 is threadedly connected to the threaded sleeve 942 on the side of the can end spraying platform 7 near the rack 853, the threaded sleeve 942 is driven to rotate synchronously. The threaded sleeve 942 then drives the gear 943 fixed on it to rotate synchronously. The gear 943 meshes with the rack 853, transmitting the rotational power to the rack 853. The rack 853 drives the spraying base 852 to move smoothly along the guide rail 851 fixed on the can end spraying platform 7. The spraying base 852 then drives the can end spraying pipe 81 and the can end nozzle 83 installed on it to move back and forth synchronously. Finally, the turbine structure inside the can end nozzle 83 rotates after the paint is pressurized, spraying the paint out in a rotating manner. By combining the rotation of the can end spraying platform 7 and the reciprocating movement of the can end nozzle 83, a comprehensive and uniform automatic spraying of the can end arc surface and edge parts is achieved without the need for additional manual intervention.

[0050] Example 2, refer to Figure 1-9 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that the reciprocating transmission assembly 9 further includes a power arm 91 disposed on the can end spraying station 7, a transmission slider 92 disposed on the can end spraying station 7, and a connecting rod 93 disposed between the power arm 91 and the transmission slider 92. The transmission slider 92 is fixedly connected to the end of the screw 941 away from the threaded sleeve 942. The power arm 91 is connected to the can end spraying station 7 by a servo waterproof motor 5. The power arm 91 is responsible for receiving power and transmitting it to subsequent components. The transmission slider 92 realizes the linear transmission of power. The connecting rod 93 coordinates the transmission relationship between the power arm 91 and the transmission slider 92. The transmission slider 92 can slide synchronously with the screw 941.

[0051] Specifically, the servo waterproof motor 5 transmits power to the power arm 91 of the reciprocating transmission assembly 9. After receiving the power, the power arm 91 coordinates the transmission relationship with the transmission slider 92 through the connecting rod 93, thereby driving the transmission slider 92 to move. Since the transmission slider 92 is fixedly connected to one end of the screw 941 extending to the threaded sleeve 942, the transmission slider 92 slides synchronously with the screw 941 when the power arm 91 moves, thereby transmitting the power linearly to the screw 941 and driving the screw 941 to slide axially.

[0052] Reference Figure 7 An adjusting slider 95 is slidably connected to the power arm 91, and an adjusting lever 96 is also rotatably connected to the power arm 91. One end of the adjusting lever 96 extends into the power arm 91 and is threadedly connected to the adjusting slider 95. The power arm 91 is hinged to the end of the connecting rod 93 away from the transmission slider 92 via the adjusting slider 95. The power arm 91 is provided with a sliding track for adjusting the slider 95. The adjusting lever 96 is connected to the threaded hole on the adjusting slider 95. The position of the adjusting slider 95 on the power arm 91 can be adjusted by rotating the adjusting lever 96, thereby changing the tilt angle of the connecting rod 93 and thus changing the stroke of the transmission slider 92. The power arm 91, through the transmission slider 92 and the connecting rod 93, together form a crank-slider transmission mechanism, which converts the rotational motion of the power arm 91 into the reciprocating linear motion of the transmission slider 92.

[0053] Specifically, when the reciprocating transmission assembly 9 is in operation, the required stroke of the transmission slider 92 is first determined according to the data of the end of the tank to be coated. The adjusting lever 96 rotatably connected to the power arm 91 is rotated. Since one end of the adjusting lever 96 extends into the power arm 91 and is threadedly connected to the adjusting slider 95 which is slidably connected to the sliding track of the power arm 91, the rotation of the adjusting lever 96 will drive the adjusting slider 95 to move along the sliding track of the power arm 91, changing the position of the adjusting slider 95 on the power arm 91. This, in turn, adjusts the tilt angle of the connecting rod 93 hinged to the adjusting slider 95. After the adjustment is completed, the power arm 91 rotates under the drive of the servo waterproof motor 5. Through the crank-slider transmission mechanism composed of the power arm 91, the transmission slider 92 and the connecting rod 93, the rotational motion of the power arm 91 is converted into the reciprocating linear motion of the transmission slider 92, realizing the conversion and transmission of power.

[0054] Reference Figure 8 and Figure 9The rotary transmission assembly 10 includes a gear ring 101 mounted on the motor frame body 6, a sun gear 102 located at the center of the gear ring 101, planet gears 103 located outside the sun gear 102, and limiting protrusions 104 mounted on the corresponding planet gears 103. The planet gears 103 are arranged in a ring array around the sun gear 102 and mesh with the sun gear 102 and the gear ring 101 respectively. The rotary transmission assembly 10 also includes a planet carrier 105 mounted on the limiting protrusions 104. The planet carrier 105 is fixedly connected to the end of the corresponding limiting protrusion 104 away from the planet gears 103. One end of the rotating shaft 72 away from the spraying station 7 at the can end is fixedly connected, and the gear ring 101 is fixed as a transmission reference. The sun gear 102 receives the power transmitted by the servo waterproof motor 5 and drives the planet gears 103 to move. The planet gears 103 mesh with both the sun gear 102 and the gear ring 101 to realize power transmission and motion conversion. The limiting shaft 104 fixes the position of the planet gears 103 and transmits rotational power. The planet carrier 105 connects each planet gear 103 to realize synchronous movement. By adjusting the speed ratio between the sun gear 102 and the planet carrier 105, the spraying station 7 at the can end can maintain synchronous rotation with the planet carrier 105 through the synchronous rotating shaft 72.

[0055] Specifically, when the rotary transmission assembly 10 is in operation, the servo waterproof motor 5 first transmits power to the sun gear 102. After receiving the power, the sun gear 102 starts to rotate. Since the planet gears 103 mesh with the sun gear 102 and the fixed gear ring 101 respectively, the rotation of the sun gear 102 will drive the planet gears 103 to revolve around the sun gear 102 while rotating on their own axis. The limiting protrusion shaft 104 on the planet gears 103 fixes the position of the planet gears 103 on the one hand, and transmits the rotational power of the planet gears 103 to the planet carrier 105 fixedly connected to it on the other hand. The planet carrier 105 connects each planet gear 103 to achieve synchronous movement. Finally, the rotation of the planet carrier 105 is transmitted to the can end spraying station 7 through the synchronous rotating shaft 72 fixedly connected to it, so that the can end spraying station 7 and the planet carrier 105 keep rotating synchronously.

[0056] When the reciprocating transmission assembly 9 operates, the adjustment lever 96 on the power arm 91 is rotated according to the required stroke of the transmission slider 92, which is related to the data of the end of the inner lining spray tank. Because the adjustment lever 96 is threadedly connected to the adjustment slider 95, which is slidably connected to the sliding rail of the power arm 91, the adjustment slider 95 will be moved to change its position, thereby adjusting the tilt angle of the connecting rod 93, which is hinged to the adjustment slider 95. After the adjustment is completed, the servo waterproof motor 5 transmits power to the power arm 91, and the power arm 91 rotates under the drive. Through the crank-slider transmission mechanism composed of the power arm 91, the transmission slider 92 and the connecting rod 93, the rotational motion is converted into the reciprocating motion of the transmission slider 92. In linear motion, since the transmission slider 92 is fixedly connected to one end of the screw 941 extending to the threaded sleeve 942, it will drive the screw 941 to slide synchronously along the axial direction. At the same time, the servo waterproof motor 5 transmits power to the sun gear 102 of the rotary transmission assembly 10. The rotation of the sun gear 102 drives the planet gears 103, which mesh with the fixed gear ring 101 respectively, to rotate on their own axis while revolving around the sun. The planet gears 103 transmit the rotational power to the planet carrier 105 through the limiting protrusion shaft 104. The planet carrier 105 connects each planet gear 103 to achieve synchronous movement. Finally, the rotation of the planet carrier 105 is transmitted to the can end spraying station 7 through the synchronous rotating shaft 72, so that the can end spraying station 7 keeps rotating synchronously with it.

[0057] The remaining structure is the same as that in Example 1.

[0058] Example 3, referring to Figure 1-10 This is the third embodiment of the present invention, which differs from the second embodiment in that: the paint conveying body 3 includes an anti-corrosion paint tank 31 disposed on the main body 1, a conveying pump 32 disposed at the top of the anti-corrosion paint tank 31, and a filling port 33 disposed on the anti-corrosion paint tank 31. The anti-corrosion paint tank 31 is fixedly installed on the top of the main body 1. The conveying pump 32 is connected to the anti-corrosion paint tank 31 through a pipeline. The anti-corrosion paint tank 31 is used to store anti-corrosion paint and can move synchronously with the main body 1. The conveying pump 32 provides power for paint conveying to ensure stable paint output. The filling port 33 is used to replenish paint in the anti-corrosion paint tank 31. The conveying pump 32 can pump the paint in the tank to each spraying mechanism through the pipeline.

[0059] Specifically, when paint needs to be transported, anti-corrosion paint is first added to the anti-corrosion paint tank 31 fixedly installed on the top of the main body 1 through the filling port 33. The anti-corrosion paint tank 31 can move synchronously with the main body 1. Then, the conveying pump 32 set on the top of the anti-corrosion paint tank 31 is started. The conveying pump 32 is connected to the anti-corrosion paint tank 31 through the pipeline to provide power for paint transport and pump the anti-corrosion paint in the tank to each spraying mechanism to ensure stable paint output.

[0060] Reference Figure 4 and Figure 10The tank wall spraying body 4 includes a nozzle seat 41 mounted on the piston rod of the electric lifting frame 2, a tank wall nozzle 42 mounted on the nozzle seat 41, a diverter pipe 43 mounted on the tank wall nozzle 42, a tank wall control valve 44 located between the tank wall nozzle 42 and the diverter pipe 43, and a telescopic interface 45 located at one end of the diverter pipe 43 extending to the outside of the tank wall nozzle 42. The tank wall nozzle 42 is rotatably connected to the piston rod in the electric lifting frame 2 via the nozzle seat 41, and the diverter pipe 43 is connected to the tank wall via the tank wall control valve 44. The nozzle 42 is connected, and the telescopic end of the telescopic interface 45 is connected to the end of the liquid supply hard pipe 82 away from the spray pipe 81 at the tank end. The nozzle seat 41 provides installation and rotation support for the tank wall nozzle 42. The tank wall nozzle 42 can be pressurized by the pump body to drive its internal turbine to rotate, thereby spraying the paint out in a rotating manner for spraying the tank wall. The tank wall control valve 44 controls the flow rate and on / off of the paint sprayed on the tank wall. The telescopic interface 45 can be extended and retracted to adapt to the position changes of the spraying mechanism and ensure the stable connection of the paint delivery pipeline.

[0061] Specifically, before the tank wall spraying operation, the nozzle seat 41 provides installation and rotation support for the tank wall nozzle 42, so that the tank wall nozzle 42 is rotatably connected to the piston rod of the electric lifting frame 2 through the nozzle seat 41. At the same time, the diversion pipe 43 is extended to the telescopic interface 45 at one end of the tank wall nozzle 42 and connected to the end of the liquid supply hard pipe 82 away from the tank end spraying pipe 81. The telescopic interface 45 is used to adapt to the subsequent position changes of the spraying mechanism, ensuring the stable connection of the paint delivery pipeline. During operation, the tank wall control valve 44 between the diversion pipe 43 and the tank wall nozzle 42 is opened. The paint flow and on / off are controlled by the tank wall control valve 44, so that the paint is delivered to the tank wall nozzle 42 through the diversion pipe 43. Then, the pump body pressurizes and drives the turbine inside the tank wall nozzle 42 to rotate, spraying the paint out in a rotating manner, thus realizing the spraying operation on the tank wall of the anti-corrosion tank.

[0062] Reference Figure 4 and Figure 8The servo waterproof motor 5 has a motor mounting rod 51 and a transmission output shaft 52 at both ends. One end of the transmission output shaft 52 is fixedly connected to the sun gear 102, and the other end of the transmission output shaft 52 passes through the spraying station 7 at the tank end and is connected to the power arm 91. The motor frame body 6 includes a reinforcing sleeve 61 and a limiting bracket 62 on the motor frame body 6. The motor frame body 6 is connected to the tank wall spray head 42 through the reinforcing sleeve 61 and fixedly connected to the gear ring 101 through the limiting bracket 62. One end of the motor mounting rod 51 passes through the reinforcing sleeve 61 and is connected to the piston rod of the electric lifting frame 2, and is rotatably connected to the turbine in the tank wall spray head 42. The motor mounting rod 51 is used to connect and fix the servo waterproof motor 5 and the electric lifting frame 2. The transmission output shaft 52 is responsible for outputting power to each transmission component. The reinforcing sleeve 61 can enhance the structural strength and provide support for related components. The limiting bracket 62 is responsible for fixing the position of the gear ring 101 and ensuring transmission stability.

[0063] Specifically, during the equipment assembly and power transmission process, the motor assembly rod 51 of the servo waterproof motor 5 is first passed through the reinforcing sleeve 61 on the motor frame body 6. One end is connected to the piston rod of the electric lifting frame 2 to fix the motor, and the other end is connected to the turbine in the tank wall spray head 42. At the same time, the position of the gear ring 101 is fixed by the limiting bracket 62 on the motor frame body 6. Then, the servo waterproof motor 5 is started. One end of its transmission output shaft 52 is fixedly connected to the sun gear 102 to transmit power to the rotary transmission component 10, and the other end passes through the tank end spraying table 7 and is connected to the power arm 91 to transmit power to the reciprocating transmission component 9, thus completing the assembly of the servo waterproof motor 5 with each component and the power output transmission.

[0064] Reference Figure 10 The bottom of the main body 1 is provided with a moving wheel 11 for movement. The main body 1 is also equipped with a grip bar 12 for gripping. The end of the grip bar 12 away from the main body 1 is inclined upward. The moving wheel 11 can be electrically driven to facilitate the flexible movement of the equipment in the tank. The braking device can fix the position of the equipment. The grip bar 12 is for the operator to grip and push the equipment in the tank.

[0065] Specifically, when moving and positioning the equipment, the operator first grasps the handle 12 that is inclined upward on the side away from the machine body 1, and pushes the equipment with the help of the moving wheels 11 at the bottom of the machine body 1, so that the equipment can move flexibly in the tank to the target spraying position. After the equipment reaches the designated position, the braking device equipped with the moving wheels 11 is activated to fix the position of the equipment.

[0066] During operation, the operator first grasps the upward-sloping handle 12 on the main body 1, away from the machine body, and pushes the equipment to the target spraying position inside the tank using the bottom moving wheels 11. The braking device of the moving wheels 11 is then activated to secure the equipment. Paint is then added to the anti-corrosion paint tank 31 at the top of the main body 1 through the filling port 33. The top-mounted delivery pump 32 is then started, pumping the paint to each spraying mechanism through pipelines. Simultaneously, the motor mounting rod 51 of the servo waterproof motor 5 is passed through the reinforcing sleeve 61 of the motor frame body 6, with one end connected to the piston rod of the electric lifting frame 2 to secure the motor, and the other end... The turbine of the tank wall spray nozzle 42 is rotated and connected. The gear ring 101 is fixed by the limiting bracket 62 of the motor frame body 6. The servo waterproof motor 5 is started, and its transmission output shaft 52 transmits power to the rotary transmission component 10 and the reciprocating transmission component 9 respectively. Before the tank wall is sprayed, the tank wall spray nozzle 42 is rotated and connected to the piston rod of the electric lifting frame 2 by means of the spray nozzle seat 41. The telescopic interface 45 of the diversion pipe 43 is connected to the liquid supply hard pipe 82. During operation, the tank wall control valve 44 is opened, and the paint is sent to the tank wall spray nozzle 42 through the diversion pipe 43. The pump body pressurizes and drives the internal turbine to rotate, and the paint is sprayed out to complete the tank wall spraying.

[0067] The remaining structure is the same as that in Example 2.

[0068] Based on embodiments 1-3, the working principle of the present invention is as follows: First, the device needs to be transferred to the chemical anti-corrosion tank to be coated with anti-corrosion lining. The operator grasps the inclined handles 12 on the main body 1 and pushes the main body 1 to the target coating position inside the tank with the help of the bottom moving wheels 11. The braking device is activated to fix the device, and the detachable counterweight on the main body 1 is installed to prevent tipping. Then, the electric lifting frame 2 is activated to adjust the height so that the first and second coating mechanisms are aligned with the axis of the anti-corrosion tank and adapted to the tank specifications. At the same time, the laser indicator 71 of the tank end coating station 7 is turned on to ensure that the tank end coating station 7 is accurately aligned with the tank end position through laser positioning.

[0069] The motor mounting rod 51 of the servo waterproof motor 5 passes through the reinforcing sleeve 61 of the motor frame body 6. One end is connected to the piston rod of the electric lifting frame 2 to fix the motor, and the other end is connected to the turbine of the tank wall spray head 42. The gear ring 101 is fixed by the limiting bracket 62 of the motor frame body 6 to ensure transmission stability. After the servo waterproof motor 5 is started, one end of its transmission output shaft 52 is fixedly connected to the sun gear 102 of the rotary transmission component 10, and the other end passes through the tank end spraying station 7 and is connected to the power arm 91 of the reciprocating transmission component 9, so that the power of the servo waterproof motor 5 can be transmitted to the tank end spraying station 7 through the rotary transmission component 10.

[0070] Based on the data at the end of the tank, the required stroke of the transmission slider 92 is determined. The adjusting lever 96 on the power arm 91 is rotated. Because the adjusting lever 96 is threadedly engaged with the adjusting slider 95 on the sliding track of the power arm 91, it drives the adjusting slider 95 to move, thereby adjusting the tilt angle of the connecting rod 93. The power arm 91 rotates after receiving power from the motor. Through the crank-slider transmission mechanism formed by the power arm 91, connecting rod 93, and transmission slider 92, the rotational motion is converted into the reciprocating linear motion of the transmission slider 92. Because the transmission slider 92 and the screw 92... 41 is fixedly connected, driving the screw 941 to slide axially. The screw 941 is threadedly engaged with the threaded sleeve 942 on the spraying platform 7 at the can end, driving the threaded sleeve 942 and the gear 943 fixed thereon to rotate. The gear 943 meshes with the rack 853 on one side of the spraying base 852, converting the rotational power into the smooth movement of the spraying base 852 along the guide rail 851, thereby driving the spraying pipe 81 at the can end and the spray nozzle 83 at the can end to move back and forth synchronously, thus covering the entire frustum-shaped arc surface of the can end for comprehensive spraying without manual intervention.

[0071] The servo waterproof motor 5 transmits power to the sun gear 102 of the rotary transmission assembly 10, driving the sun gear 102 to rotate. Since the planet gears 103 mesh with the sun gear 102 and the fixed gear ring 101 respectively, the sun gear 102 drives the planet gears 103 to revolve around the sun gear and rotate on their own axis. The planet gears 103 transmit the rotational power to the planet carrier 105 through the limiting protrusion shaft 104. The planet carrier 105 connects each planet gear 103 to achieve synchronous movement. The rotation of the planet carrier 105 is transmitted to the can end spraying station 7 through the synchronous rotating shaft 72, so that the can end spraying station 7 rotates synchronously with the planet carrier 105, thereby spraying the can end area in a way that surrounds the axis of the can body.

[0072] The anti-corrosion paint tank 31 on top of the main body 1 is pre-filled with paint through the filling port 33. The delivery pump 32 is started, and the paint is pumped through the pipeline to the liquid supply hard pipe 82 and the diversion pipe 43. When the can end is sprayed, the relevant control valves are opened, and the paint is delivered to the can end spraying pipe 81 through the liquid supply hard pipe 82. The turbine inside the can end nozzle 83 rotates after the paint is pressurized, and sprays the paint out in a rotating manner. Combined with the rotation of the can end spraying platform 7 and the reciprocating movement of the can end nozzle 83, the can end arc surface and edge are fully and evenly sprayed. When the can wall is sprayed... The tank wall spray head 42 is rotatably connected to the piston rod of the electric lifting frame 2 via the spray head base 41. The telescopic interface 45 of the diversion pipe 43 is connected to the liquid supply hard pipe 82. When the spray pipe 81 at the tank end moves, the telescopic interface 45 adapts to the position change to ensure pipeline stability. The flow rate and on / off of the paint are controlled by opening the tank wall control valve 44. The paint is transported to the tank wall spray head 42 through the diversion pipe 43. The pump body pressurizes and drives the turbine of the tank wall spray head 42 to rotate, spraying the paint out in a rotating manner to complete the tank wall spraying until the entire chemical anti-corrosion tank is sprayed.
