Description

[0002] As high-pressure containers, gas cylinders play a vital role in the storage and transportation of compressed gases. However, after long-term exposure to complex and changing environments, a layer of rust often accumulates on the surface of gas cylinders, which not only affects the neatness of the appearance of the gas cylinders, but more importantly, may pose a potential threat to their structural strength and sealing performance. The accumulation of rust will gradually weaken the wall thickness of the gas cylinder, increase its risk of rupture under high pressure, and thus endanger the safety of personnel and equipment.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 10 As shown, the present invention is a rust removal device for a gas cylinder, comprising: a body 1, a rust removal mechanism 2 for removing rust from the surface of the gas cylinder; the rust removal mechanism 2 comprises: a side rust removal component 21, and an end rust removal component 22; the gas cylinder is polished as a whole by the side rust removal component 21 and the end rust removal component 22 to ensure the rust removal effect on the surface of the gas cylinder. In addition, the device can be set in multiple groups for combination to improve the rust removal efficiency of the gas cylinder.

[0024] In existing designs, in order to enhance the structural stability of the bottom of the steel cylinder, the bottom of the steel cylinder is usually rounded, which increases the difficulty of grinding.

[0025] The end surface rust removal assembly 22 includes: a linear moving module 221 fixedly mounted on the machine body 1, an adjustment platform 222 fixedly mounted on the linear moving module 221, and an end grinding piece 225 for removing rust from the end surface of the gas cylinder; the linear moving module 221 is provided with two groups, which are respectively used to drive the adjustment platform 222 and the adjustment block 211 to move. The linear moving module 221 drives the adjustment platform 222 to move, and moves the gas cylinder away from the grinding position, so as to facilitate loading and unloading of the gas cylinder and improve the loading speed of the gas cylinder.

[0026] The end grinding member 225 includes: a transmission gear 2251, a grinding plate 2252 slidably connected to the transmission gear 2251, and a support plate 2253 fixedly connected to the adjustment platform 222. Two groups of grinding plates 2252 are provided, one group of grinding plates 2252 is fixedly connected to an adjustment plate 2254, and the other group of grinding plates 2252 is fixedly connected to a fixed plate 2255, and the fixed plate 2255 is fixedly connected to an electric telescopic rod 2256, and the output end of the electric telescopic rod 2256 is fixedly connected to the adjustment plate 2254, and the adjustment plate 2254 is slidably connected to the fixed plate 2255. In addition, a driving motor 2221 is fixedly installed on the adjustment platform 222, and a transmission gear 1 2222 is fixedly connected to the driving motor 2221, and the transmission gear 1 2222 is meshed with the transmission gear 2 2251, and the shape of the grinding plate 2252 is an arc-shaped plate that matches the arc shape of the end of the gas cylinder.

[0027] When in use, the driving motor 2221 drives the transmission gear 1 2222 to rotate, so that the transmission gear 2 2251 drives the grinding plate 2252 to rotate to grind and remove rust from the end of the gas cylinder, and drives the adjustment plate 2254 and a group of grinding plates 2252 to move through the electric telescopic rod 2256, so that the distance between the two groups of grinding plates 2252 is closer, which helps to increase the grinding depth of the gas cylinder and achieve a better grinding effect. In addition, the support plate 2253 is provided with multiple groups of through holes, and the rust residue generated when grinding the end of the gas cylinder falls onto the support plate 2253 and falls out through the through holes, so as to prevent the rust residue from affecting the grinding effect of the gas cylinder.

[0028] To facilitate the transportation of gas cylinders, gas cylinders are generally transported in a horizontal position. However, when grinding gas cylinders, the gas cylinders need to be changed from horizontal to vertical, which invisibly increases the difficulty of loading materials for the staff and work efficiency. The present application assists the staff in loading materials through a loading component 2211 that drives the gas cylinders to load materials, thereby reducing the labor intensity of the staff and improving work efficiency. In addition, the loading component 2211 is used in conjunction with a small scissor lift, and the gas cylinder is placed on a gas cylinder cart and sent to the small scissor lift together with the gas cylinder cart to ensure that the gas cylinder is at the same height as the loading component 2211, thereby minimizing the difficulty of the staff in carrying the gas cylinders.

[0029] The loading assembly 2211 includes: a support frame 22111 fixedly mounted on the machine body 1, a rotating member 22112 fixedly mounted on the support frame 22111, a loading member 22113 rotatably connected to the rotating member 22112, a rotating shaft 22114 fixedly mounted on the loading member 22113, a support block 22115 rotatably connected to the rotating shaft 22114, and a chamfer 22116 provided on the support block 22115. The support blocks 22115 are provided in two groups, and the chamfers 22116 are provided on adjacent surfaces of the two groups of support blocks 22115. A limiting groove 221111 is provided on the support frame 22111, a spring 221121 is fixedly installed on the rotating member 22112, one end of the spring 221121 is fixedly connected to the feeding member 22113, a torsion spring is fixedly installed on the rotating shaft 22114, one end of the torsion spring is fixedly connected to the support block 22115.

[0030] A limit block cooperating with the limit groove 221111 is fixedly mounted on the rotating member 22112. When the rotating member 22112 rotates, the limit block is driven to rotate in the limit groove 221111. When there is no gas cylinder on the loading member 22113, the loading member 22113 is tilted under the action of spring 1 221121.

[0031] Pull the bottom end of the gas cylinder (the end away from the gas outlet end of the gas cylinder is the bottom end) to move the gas cylinder onto the loading piece 22113. At this time, only a part of the gas cylinder is placed on the loading piece 22113, and the loading piece 22113 will not rotate due to the interference of the limit block and the limit groove 221111. When the gas cylinder is completely placed on the loading piece 22113, the weight of the gas cylinder will drive the loading piece 22113 to rotate through the rotating piece 22112 and enter the pre-loading state, and the bottom end of the gas cylinder enters the support block 22115 and is resisted by the blocking block fixed inside the support block 22115 to prevent the gas cylinder from continuing to move. At the same time, the spring 221121 is deformed under force.

[0032] After the gas cylinder is polished, it needs to be loaded and unloaded. The control adjustment platform 222 drives the gas cylinder to move away from the axis of the lifting sleeve 213 through the linear moving module 221, and then unloading is carried out. Then the adjustment platform 222 is continued to be controlled to continue to move in the direction of the upper material 22113, so that the vertical rod 223 squeezes the support block 22115 through the chamfer 22116, and the support block 22115 rotates through the rotating shaft 22114. At this time, the blocking block can no longer block the gas cylinder, so that the gas cylinder falls onto the end polishing piece 225 to complete the loading. It should be noted that the electric telescopic rod 2256 drives the adjustment plate 2254 and a group of polishing plates 2252 to move, so that the distance between the two groups of polishing plates 2252 is closer, so that the gas cylinder can be clamped to avoid shaking of the gas cylinder when the gas cylinder is driven to move.

[0033] The spring 1 221121 and the torsion spring are deformed, and after the gas cylinder is loaded, they respectively drive the loading piece 22113 and the supporting block 22115 to reset.

[0034] The side rust removal component 21 includes: an adjusting block 211, a limiting hole 212 provided on the adjusting block 211, a lifting sleeve 213 fixedly installed on the adjusting block 211, a driving gear 214 rotatably installed on the lifting sleeve 213, an annular block 215 meshing with the driving gear 214, a side grinding piece 216 slidably installed on the annular block 215, and a power source 1 for driving the driving gear 214 to rotate; the adjusting block 211 is fixedly installed on the linear moving module 221; when grinding and derusting the gas cylinder, the gas cylinder needs to be installed on the axis of the lifting sleeve 213, so that the linear moving module 221 drives the adjusting block 211 and the lifting sleeve 213 to move, and the lifting sleeve 213 is sleeved on the outer surface of the gas cylinder to facilitate grinding and derusting the outer surface of the gas cylinder.

[0035] Specifically, the power source 1 drives the driving gear 214 to rotate, so that the annular block 215 rotates, and drives the side grinding piece 216 to grind the surface of the gas cylinder. It should be noted that there are multiple groups of side grinding pieces 216 arranged in an array with equal spacing around the center of the annular block 215, and a power source 2 is fixedly installed on one side of the side grinding piece 216. The power source 2 pushes the side grinding piece 216 to move, so that the side grinding piece 216 can increase the grinding depth when removing rust from the gas cylinder, thereby improving the grinding effect on the gas cylinder.

[0036] In addition, when the power source 2 pushes the side grinding piece 216 to move, the power source 1 stops working to fix the gas cylinder, that is, when the side of the gas cylinder is being grinded, the driving motor 2221 stops working, and the electric telescopic rod 2256 pulls the grinding plate 2252 to fix the gas cylinder, and when the end of the gas cylinder is being grinded, the power source stops working, and the power source 2 drives the side grinding piece 216 to fix the gas cylinder. The power source 1 can be a motor, and the power source 2 can be a telescopic cylinder.

[0037] One point that needs to be added is that since the adjusting platform 222 needs to move the gas cylinder away from the axial position of the lifting sleeve 213 to load and unload the gas cylinder, the position of the adjusting platform 222 before and after the movement may deviate, resulting in excessive coaxial deviation between the gas cylinder and the lifting sleeve 213, making it impossible to grind the gas cylinder.

[0038] By fixing the vertical rod 223 on the adjustment platform 222, the vertical rod 223 cooperates with the limiting hole 212, so that when the lifting sleeve 213 descends, if the adjustment block 211 slides on the surface of the vertical rod 223 through the limiting hole 212, it can ensure that the position of the adjustment platform 222 after moving has been corrected. If the coaxiality deviation between the gas cylinder and the lifting sleeve 213 is too large, when the adjustment block 211 and the lifting sleeve 213 move downward, interference will occur between the vertical rod 223, so that the lifting sleeve 213 cannot move downward normally, so that the staff can make corrections in time. By observing whether the vertical rod 223 interferes with the movement of the lifting sleeve 213, it is judged whether the coaxiality between the gas cylinder and the lifting sleeve 213 meets the processing standard to avoid affecting the grinding effect of the gas cylinder.

[0039] In the present application, on the one hand, by observing whether there is interference in the movement between the vertical rod 223 and the adjustment block 211, it is judged whether the coaxiality of the gas cylinder and the lifting sleeve 213 meets the processing standards. On the other hand, the vertical rod 223 squeezes the support block 22115 through the chamfer 22116 to realize the loading of the gas cylinder, and the use effect is good.

[0040] The side rust removal assembly 21 also includes: a pressure tank 2111 fixedly mounted on the machine body 1, a slag removal port 217 opened on the annular block 215, and a hose 218 connecting the lifting sleeve 213 and the pressure tank 2111; the slag removal port 217 is connected to the annular block 215, the annular block 215 is connected to the lifting sleeve 213, the lifting sleeve 213 is fixedly connected to the connecting rod 2113, and the pressure tank 2111 is divided into a slag removal chamber and a cooling chamber by the sealing plug 2114.

[0041] During the movement of the lifting sleeve 213, the connecting rod 2113 is driven to move, and the connecting rod 2113 pushes the sealing plug 2114 to move, so that the internal pressure of the slag removal chamber is reduced. Driven by the external pressure, the rust slag generated during the grinding process of the side grinding part 216 enters the slag removal chamber through the slag removal port 217 and the hose 218, thereby reducing the risk of rust slag splashing and causing inhalation by the staff during the grinding process.

[0042] The pressure tank 2111 is slidably connected with a sealing plate 2112, the inner wall of the pressure tank 2111 is slidably connected with a sealing plug 2114, the pressure tank 2111 is slidably connected with a connecting rod 2113, the sealing plug 2114 is slidably connected with a guide plate 2116, the sealing plug 2114 is fixedly installed with a baffle 2115, the guide plate 2116 is fixedly connected with the connecting rod 2113, the connecting rod 2113 penetrates the baffle 2115, when the connecting rod 2113 pushes the guide plate 2116 to move downward, the guide plate 2116 moves to the sealing plug 2114, 14 bottom, and then drives the sealing plug 2114 to move synchronously. At this time, the rust residue generated during the external grinding is sucked in, and due to the inclined setting of the guide plate 2116, the rust residue moves toward the inside of the sealing plug 2114 on the guide plate 2116. When the connecting rod 2113 moves upward, the guide plate 2116 is pulled to move upward inside the sealing plug 2114 and abuts against the baffle 2115, and then the sealing plug 2114 is pulled upward as a whole. At this time, the rust residue is sealed inside the sealing plug 2114 and will not be discharged with the gas, thereby completing the collection of rust residue during the grinding process of the gas cylinder.

[0043] It should also be noted that when the connecting rod 2113 moves upward, it is necessary to control power source 2 to drive the side grinding piece 216 to leave the surface of the gas cylinder, and at the same time, power source 1 stops working to prevent the side grinding piece 216 from still grinding the gas cylinder when the pressure in the pressure tank 2111 is discharged, causing rust residue to fly out. On the one hand, when the pressure is discharged, the side grinding piece 216 stops grinding the gas cylinder. At this time, the side grinding piece 216 can be cooled down when the pressure in the pressure tank 2111 is discharged. On the other hand, the side grinding piece 216 only grinds and removes rust on the gas cylinder when moving downward, which can improve the consistency of the gas cylinder surface.

[0044] To avoid interference between the connecting rod 2113 and the pressure tank 2111 when the connecting rod 2113 moves downward, when the connecting rod 2113 and the pressure tank 2111 are in contact, the connecting rod 2113 continues to move downward to drive the sealing plate 2112 to slide on the pressure tank 2111 without interference.

[0045] The end face rust removal assembly 22 also includes: a cooling member 224 fixedly mounted on the adjusting platform 222, and an adjusting rod 2241 slidably connected to the cooling member 224, connecting blocks 2242 respectively fixedly connected to the cooling member 224 and the adjusting rod 2241, a spring 2243 fixedly mounted on the two groups of connecting blocks 2242, a discharge port 2244 opened on the cooling member 224, and a sealing member 2245 fixedly mounted on the body 1; the cooling member 224 is connected to the pressure tank 2111, the cooling member 224 is a hollow tube body, a cavity is opened on the body 1, and is used to store liquid flowing out of the cooling member 224, and an atomizing nozzle is installed on the adjusting rod 2241.

[0046] When the sealing plug 2114 moves downward in the pressure tank 2111, the coolant in the cooling chamber is discharged to the cooling element 224, and the adjusting rod 2241 is driven to move upward, and the distance between the two sets of connecting blocks 2242 is increased. At the same time, the spring 2243 is deformed under force. When the adjusting rod 2241 cannot move upward, the sealing plug 2114 continues to move to spray the coolant through the atomizing nozzle to cool the gas cylinder, and the use effect is good. Finally, when the gas cylinder is polished, the adjusting table 222 moves, driving the cooling element 224 to move away from the sealing element 2245, so that the discharge port 2244 is exposed. At this time, the coolant inside the cooling element 224 flows out through the discharge port 2244 under the action of gravity and the resetting action of the spring 2243 after deformation, which is convenient for subsequent use.

[0047] When the lifting sleeve 213 moves to grind and remove rust from the side of the gas cylinder, on the one hand, the rust residue generated during the grinding process can be sucked into the sealing plug 2114 through the residue removal port 217 for storage, thereby preventing the rust residue from spreading in the air and affecting the staff; on the other hand, the coolant in the cooling chamber is discharged to form water mist around the gas cylinder, thereby further reducing the dust on the rust residue and lowering the temperature during grinding and rust removal.
