Existing gas tank surface inspection usually adopts the method of manually grinding the surface, or clamping the gas tank with a clamp, then cleaning the surface, and finally inspecting the degree of rust on the surface of the gas tank by manual measurement. This process consumes a lot of manpower and time. Summary of the invention

Then the controller controls the clamping device to start, and several clamping groups move to the side close to the gas tank to complete the clamping and fixation of the gas tank. Then the clamping group cleans and inspects the surface of the gas tank, removes the oxidized rust layer on the surface of the gas tank, and uses the expanded detection bag to detect the degree of rust on the surface of the gas tank. By identifying the change in pressure, it is used to reflect the rust condition of the surface of the gas tank, thereby realizing the function of pressure feedback detection and improving the detection efficiency of the surface of the gas tank.

[0009] When the gas tank is hoisted above the collecting platform, the controller immediately controls the No. 1 motor to start, and the driving shaft of the No. 1 motor drives the telescopic arm to rotate, so that the telescopic arm rotates toward the side close to the gas tank. During the rotation of the telescopic arm, the rotating arm is driven to move. While the rotating arm moves toward the gas tank, the controller controls the No. 2 motor to start, and the driving shaft of the No. 2 motor drives the rotating arm to rotate around the axis of the driving shaft of the No. 2 motor, so that the axis of the clamping body is always parallel to the axis of the gas tank. If the height of the gas tank is high, the controller controls the hydraulic cylinder in the telescopic arm to start, and the hydraulic cylinder extends the telescopic arm. The rotation angles of the telescopic arm and the rotating arm are adjusted by driving the No. 1 motor and the No. 2 motor, so that the clamping body can clamp the surface of the gas storage tank. Several clamping bodies can suspend and fix the gas storage tank above the collecting platform. When the gas tank is clamped and fixed, the controller controls the driving motor in the fixed table to drive, and the driving shaft of the driving motor drives the driving gear to rotate. When the driving gear rotates, it engages with the gear rings on the collecting table and the rotating table, thereby driving the rotating table and the collecting table to rotate. Under the action of the driving gear, the rotating table and the collecting table rotate in opposite directions, and then the rotating table drives the clamping group to rotate. When the clamping group rotates, it drives the gas tank to rotate.

[0010] Preferably, a clamping body is provided on the side of the rotating arm away from the telescopic arm, the clamping body consists of a central body and two clamping plates, the two clamping plates are symmetrically arranged on both sides of the central body, the clamping plates are rotatably connected to the central body, a sealing strip is provided between the clamping plates and the central body, extension plates are symmetrically provided on the upper and lower sides of the central body, the extension plates are made of rubber, a detection bag is provided between the two extension plates, a pressure sensor is provided in the detection bag, a gas supply port is provided on the side of the central body close to the detection bag, an air pump is provided on the outside of the rotating arm, and the air pump is connected to the gas supply port through a pipeline.

[0013] Preferably, a driving group is provided at the top of the rotating arm, and the driving group is composed of a driving platform and a transmission body. A ball table is provided at the top of the driving platform, and a spherical gear is provided on the side of the transmission body close to the ball table, and the spherical gear is meshed with the ball table. A No. 3 motor is provided in the ball table, and the No. 3 motor is used to drive the spherical gear.

[0014] Preferably, a driving wheel is provided on the side of the transmission body away from the spherical gear, a No. 4 motor is provided inside the transmission body, a driving shaft of the No. 4 motor is connected to the driving wheel, and the driving wheel is in contact with the surface of the gas tank.

[0015] Preferably, spiral teeth are arranged on the outer wall of the driving wheel, and a vibration generator is arranged inside the driving wheel.

[0016] When the rotating arm drives the clamping body to move toward the gas tank, the controller controls the micro motor to start, and the driving shaft of the micro motor drives the transmission wheel to rotate. When the transmission wheel rotates, it contacts with the slideway by friction. Then, the slider moves along the slideway under the action of the transmission wheel. When the slider moves, it pushes the pull rod, and the pull rod immediately pushes the clamping plate to rotate. The clamping plate rotates toward the side close to the gas tank. When the diameter of the space surrounded by several clamping plates is equal to the diameter of the gas tank, the slider stops moving, and then the central body moves toward the gas tank under the action of the rotating arm. During the movement, the extension plate first contacts the surface of the gas tank. Since the extension plate is made of rubber, the extension plate is squeezed by the central body and the gas tank, so that the space surrounded by the gas tank, the central body and the two extension plates is isolated from the outside world. When the clamping body has finished clamping the gas tank, the controller controls the No. 3 motor in the driving platform to start, and the No. 3 motor drives the spherical gear to rotate, so that the spherical gear drives the transmission body to move toward the side close to the gas tank. When the transmission body rotates, it drives the driving wheel to rotate. During the rotation of the driving wheel, it contacts the surface of the gas tank, and the axis of the driving wheel forms an angle with the axis of the gas tank. When the driving wheel contacts the gas tank, the controller controls the air pump to start, and the air pump extracts the outside air, and then transmits it to the gas delivery port through the pipeline, and then transmits it to the detection bag through the delivery port. As the gas in the detection bag continues to increase, the detection bag expands and contacts the surface of the gas tank. At this time, the pressure sensor detects the pressure in the detection bag and transmits it to the controller as the reference pressure; Then the controller starts the external water pump, which draws water and delivers it to the water delivery port through the pipeline. The water flows to the flow channel in the rotating arm through the water delivery port, and then is delivered to the water spray port through the flow channel. Finally, the water is sprayed to the gap between the extension plate and the shovel plate through the water spray port. The pressurized water source is sprayed along the shovel plate to the oxidized rust layer on the surface of the gas tank. While the water spraying port sprays water, the controller controls the No. 4 motor and the vibration generator to start, and the driving shaft of the No. 4 motor drives the driving wheel to rotate. When the driving wheel rotates, it comes into frictional contact with the gas storage tank. The friction between the driving wheel and the gas storage tank is greater than the friction between the extension plate and the gas storage tank, and the axis of the driving wheel forms an angle with the axis of the gas storage tank, so that the driving wheel drives the gas storage tank to move toward the side close to the collection platform in the form of spiral rotation; When the gas tank is spirally rotating, since the surface of the driving wheel is provided with spiral teeth, and the vibration generator generates vibration after being turned on, the spiral teeth and the vibration cooperate with each other to first squeeze and crush the oxidized rust layer on the surface of the gas tank, making the oxidized rust layer loose, and then the shovel plate and the pressurized water source cooperate with each other to scrape and clean the oxidized rust layer with water pressure impact, so that the oxidized rust layer falls off from the surface of the gas tank, thereby completing the cleaning of the surface of the gas tank; After the surface of the gas tank is cleaned, the clean outer wall of the gas tank is moved to the space surrounded by the gas tank, the central body and the two extension plates, and the detection bag detects its surface. Due to the influence of the oxidized rust layer, pits will appear on the outer wall of the gas tank, thereby increasing the volume of the space surrounded by the gas tank, the central body and the two extension plates. At this time, the volume in the detection bag is constant. When the detection bag encounters the pit position, the detection bag will expand to the pit area, thereby increasing the volume of the detection bag, which in turn causes the pressure in the detection bag to decrease. The degree of pressure reduction can be analyzed by the pressure sensor to obtain the degree of rust of the pit here. If the degree of pressure reduction is small, the rusted surface is shallow, and repairs can be made later. If the degree of pressure reduction is large, the rusted surface is deep, and repairs are not meaningful. The feedback of pressure changes can be used to detect the degree of rust on the surface of the gas tank. Compared with visual inspection, the depth of rust on the gas tank can be detected, avoiding the subsequent measurement of the depth of rust by manual monitoring, thereby improving the effect of surface inspection of the gas tank. The cleaned impurities in the rust layer flow along the water to the collection table. Since the collection table is also in a rotating state, the water flows to the edge of the collection table and is discharged through the drain port, while the impurities move to the rotation center of the collection table and are stored on the collection table and separated from the water.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the gas tank is spirally rotated, since the surface of the driving wheel is provided with spiral teeth, and the vibration generator generates vibration after being turned on, the spiral teeth and the vibration cooperate with each other to first squeeze and crush the oxidized rust layer on the surface of the gas tank, making the oxidized rust layer loose, and then the shovel plate and the pressurized water source cooperate with each other to scrape and clean the oxidized rust layer with water pressure impact, so that the oxidized rust layer falls off from the surface of the gas tank, thereby completing the cleaning of the surface of the gas tank.

[0018] 2. After the surface of the gas tank is cleaned, the clean outer wall of the gas tank is moved to the space surrounded by the gas tank, the center body and the two extension plates, and the detection bag detects its surface. Due to the influence of the oxidized rust layer, pits will appear on the outer wall of the gas tank, thereby increasing the volume of the space surrounded by the gas tank, the center body and the two extension plates. At this time, the volume in the detection bag is constant. When the detection bag encounters the pit position, the detection bag will expand to the pit area, thereby increasing the volume of the detection bag, and then causing the pressure in the detection bag to decrease. The degree of pressure reduction by the pressure sensor can be used to analyze the degree of rust in the pit here. If the degree of pressure reduction is small, the rusted surface is shallow, and repairs can be made later. If the degree of pressure reduction is large, the rusted surface is deep, and repairs are not meaningful. The feedback of pressure changes can be used to detect the degree of rust on the surface of the gas tank. Compared with visual inspection, the depth of rust on the gas tank can be detected, avoiding the subsequent measurement of the depth of rust by manual monitoring, thereby improving the effect of surface inspection of the gas tank.

[0030] As a specific implementation of the present invention, spiral teeth are arranged on the outer wall of the driving wheel 31 , and a vibration generator is arranged inside the driving wheel 31 .

[0031] Working principle of the present invention: When the gas tank is hoisted above the collecting platform 13, the controller immediately controls the No. 1 motor to start, and the driving shaft of the No. 1 motor drives the telescopic arm 23 to rotate, so that the telescopic arm 23 rotates toward the side close to the gas tank. During the rotation of the telescopic arm 23, the rotating arm 24 is driven to move. While the rotating arm 24 moves toward the gas tank, the controller controls the No. 2 motor to start, and the driving shaft of the No. 2 motor drives the rotating arm 24 to rotate around the axis of the driving shaft of the No. 2 motor, so that the axis of the clamping body 25 is always parallel to the axis of the gas tank. If the height of the gas tank is high, the controller controls the hydraulic cylinder in the telescopic arm 23 to start, and the hydraulic cylinder extends the telescopic arm 23. The rotation angles of the telescopic arm 23 and the rotating arm 24 are adjusted by driving the first motor and the second motor, so that the clamping body 25 clamps the surface of the gas storage tank. A plurality of clamping bodies 25 suspend and fix the gas storage tank above the collecting platform 13. When the gas tank is clamped and fixed, the controller controls the driving motor in the fixing table 11 to drive, and the driving shaft of the driving motor drives the driving gear 15 to rotate. When the driving gear 15 rotates, it meshes with the gear ring 14 on the collecting table 13 and the rotating table 12, thereby driving the rotating table 12 and the collecting table 13 to rotate. Under the action of the driving gear 15, the rotating table 12 and the collecting table 13 rotate in opposite directions, and then the rotating table 12 drives the clamping group 21 to rotate. When the clamping group 21 rotates, it drives the gas tank to rotate; When the rotating arm 24 drives the clamping body 25 to move toward the gas tank, the controller controls the micro motor to start, and the driving shaft of the micro motor drives the transmission wheel to rotate. When the transmission wheel rotates, it contacts with the slideway 242 by friction. Then the slider 243 moves along the slideway 242 under the action of the transmission wheel. When the slider 243 moves, it pushes the pull rod 244. The pull rod 244 then pushes the clamping plate 27 to rotate. The clamping plate 27 rotates toward the side close to the gas tank. When the diameter of the space surrounded by the plurality of clamping plates 27 is equal to the diameter of the gas tank, the slider 243 stops moving. Then the central body 26 moves toward the gas tank under the action of the rotating arm 24. During the movement, the extension plate 261 first contacts the surface of the gas tank. Since the extension plate 261 is made of rubber, the extension plate 261 is squeezed by the central body 26 and the gas tank, so that the space surrounded by the gas tank, the central body 26 and the two extension plates 261 is isolated from the outside world. When the clamping body 25 has finished clamping the gas tank, the controller controls the No. 3 motor in the driving platform 29 to start, and the No. 3 motor drives the spherical gear 301 to rotate, so that the spherical gear 301 drives the transmission body 30 to move toward the side close to the gas tank. When the transmission body 30 rotates, it drives the driving wheel 31 to rotate. During the rotation of the driving wheel 31, it contacts the surface of the gas tank, and the axis of the driving wheel 31 forms an angle with the axis of the gas tank. When the driving wheel 31 contacts the gas tank, the controller controls the air pump to start, the air pump extracts the outside air, and then delivers it to the gas delivery port through the pipeline, and then delivers it to the detection bag 262 through the delivery port. As the gas in the detection bag 262 continues to increase, the detection bag 262 expands and contacts the surface of the gas tank. At this time, the pressure sensor detects the pressure in the detection bag 262 and transmits it to the controller as a reference pressure. Then the controller starts the external water pump, and the water pump draws water, delivers it to the water delivery port 241 through the pipeline, flows to the flow channel in the rotating arm 24 through the water delivery port 241, and then delivers it to the water spray port 273 through the flow channel, and finally sprays it to the gap between the extension plate 272 and the shovel plate 271 through the water spray port 273, and the pressurized water source sprays along the shovel plate 271 to the oxidized rust layer on the surface of the gas storage tank; While the water outlet 273 sprays water, the controller controls the No. 4 motor and the vibration generator to start, and the driving shaft of the No. 4 motor drives the driving wheel 31 to rotate. When the driving wheel 31 rotates, it comes into frictional contact with the gas tank. The friction between the driving wheel 31 and the gas tank is greater than the friction between the extension plate 261 and the gas tank, and the axis of the driving wheel 31 forms an angle with the axis of the gas tank, so that the driving wheel 31 drives the gas tank to move toward the side close to the collecting platform 13 in the form of spiral rotation; When the gas tank is spirally rotated, since the surface of the driving wheel 31 is provided with spiral teeth, and the vibration generator is turned on to generate vibration, the spiral teeth and the vibration cooperate with each other to first squeeze and crush the oxidized rust layer on the surface of the gas tank, so that the oxidized rust layer becomes loose, and then the shovel plate 271 cooperates with the pressurized water source to scrape and clean the oxidized rust layer with water pressure impact, so that the oxidized rust layer falls off from the surface of the gas tank, thereby completing the cleaning of the surface of the gas tank; After the surface of the gas tank is cleaned, the clean outer wall of the gas tank moves to the space surrounded by the gas tank, the central body 26 and the two extension plates 261, and the detection capsule 262 detects its surface. Due to the influence of the oxidized rust layer, pits will appear on the outer wall of the gas tank, thereby increasing the volume of the space surrounded by the gas tank, the central body 26 and the two extension plates 261. At this time, the volume in the detection capsule 262 is constant. When the detection capsule 262 encounters the pit position, the detection capsule 262 will expand to the pit area, thereby increasing the volume of the detection capsule 262. , which leads to a decrease in the pressure in the detection capsule 262. The degree of pressure reduction can be analyzed by the pressure sensor to obtain the degree of corrosion of the pit. If the degree of pressure reduction is small, the rust surface is shallow and can be repaired and supplemented later. If the degree of pressure reduction is large, the rust surface is deep and repair is meaningless. The degree of corrosion on the surface of the gas tank can be detected by feedback of pressure changes. Compared with visual detection, the depth of corrosion of the gas tank can be detected, avoiding the need to measure the depth of corrosion through manual monitoring later. The cleaned impurities in the rust layer flow along the water to the collecting table 13. Since the collecting table 13 is also in a rotating state, the water flows to the edge of the collecting table 13 and is discharged through the drain port 131, while the impurities move to the rotation center of the collecting table 13 and are stored on the collecting table 13 and separated from the water.
