Description

Technical Field

[0001] The utility model relates to the technical field of rust removal of gas cylinders, in particular to a device for removing rust from the inner wall of a steel gas cylinder. Background Art

[0002] After long-term use, some rust will form inside the steel gas cylinder, which needs to be cleaned and rust-removed. If it is not cleaned, it is easy to cause damage to the gas cylinder, affecting its storage and use. In order to improve the stability during rust removal, the existing steel gas cylinder inner wall rust removal device usually uses two sets of positioning clamps to cooperate with the cylinder to clamp it in place during the rust removal process.

[0003] However, the above-mentioned rust removal device for the inner wall of a steel gas cylinder with a positioning structure is not very stable when in use. Since the splint is usually a flat plate and the outer surface of the gas cylinder is arc-shaped, the contact area between the splint and the gas cylinder is small, and the friction between the grinding part and the gas cylinder is large during rust removal, which makes it easy for the gas cylinder to shift during the rust removal process, which not only reduces the rust removal effect, but also poses certain safety hazards.

[0004] Therefore, we have designed a steel gas cylinder inner wall rust removal device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a device for removing rust from the inner wall of a steel gas cylinder to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model provides a rust removal device for the inner wall of a steel gas cylinder, comprising a processing table, a rust removal component arranged at one end of the top of the processing table, and a U-shaped box arranged at the other end of the top of the processing table, wherein one side of the U-shaped box is symmetrically slidably provided with two positioning bars, including:

[0007] There are two fixing parts, which are fixedly connected to the positioning strip;

[0008] The number of the clamping parts is the same as that of the fixing parts, and the clamping parts are located between the two fixing parts, with a spacing between the clamping parts and the fixing parts. The clamping parts are made of a deformable material and are used to deform and wrap around the surface of the gas cylinder to be polished;

[0009] There are two first electric push rods, which are symmetrically rotatably installed between the fixing member and the clamping member.

[0010] Furthermore,

[0011] There are two groups of mounting seats, with two mounting seats in each group. The two mounting seats in each group are arranged on the same vertical line and are respectively installed on the side opposite to the fixing member and the clamping member.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The utility model provides a technical solution: a rust removal device for the inner wall of a steel gas cylinder, comprising a processing table 1, a rust removal component 14 arranged at one end of the top of the processing table 1, and a U-shaped box 2 arranged at the other end of the top of the processing table 1. Two positioning bars 3 are symmetrically slidably provided on one side of the U-shaped box 2, including:

[0027] There are two fixing members 4, which are fixedly connected to the positioning strip 3;

[0028] The number of the clamping members 5 is the same as that of the fixing members 4, and the clamping members 5 are located between the two fixing members 4, with a spacing between the clamping members 5 and the fixing members 4. The clamping members 5 are made of a deformable material and are used to deform and wrap around the surface of the gas cylinder to be polished;

[0029] There are two first electric push rods 6, which are symmetrically mounted between the fixing member 4 and the clamping member 5;

[0030] Also includes,

[0031] There are two groups of mounting seats 7, with two in each group. The two mounting seats 7 in each group are arranged on the same vertical line and are respectively installed on the side opposite to the fixing member 4 and the clamping member 5. The two ends of the first electric push rod 6 are respectively rotatably connected to the two mounting seats 7. It also includes a driving assembly for driving the two clamping members 5 to clamp and position the gas cylinder. The driving assembly includes a screw rod 11, which is rotatably installed in the U-shaped box 2. The positioning bar 3 is threadedly sleeved on the screw rod 11. A motor 12 is provided on the top of the U-shaped box 2. The drive shaft of the motor 12 rotates and extends through the U-shaped box 2 to the inside of the U-shaped box 2 and is transmission-connected to one end of the screw rod 11.

[0032] During the specific implementation, the steel gas cylinder to be derusted is first placed in the U-shaped box 2 and located between the two clamping members 5. Then, the motor 12 is turned on to rotate the screw rod 11, so that the two positioning bars 3 drive the two fixing members 4 and the clamping member 5 to approach each other until they are against the steel gas cylinder to be derusted. Then, the first electric push rod 6 is turned on to extend the driving end of the first electric push rod 6. Since the clamping member 5 is made of a deformable material, the driving end of the first electric push rod 6 can push the clamping member 5 to deform and bend and adhere to the surface of the gas cylinder, so that the gas cylinder can be completely wrapped, thereby improving the positioning effect of the gas cylinder and avoiding safety problems such as shaking when derusting the gas cylinder. Finally, in conjunction with the rust removal component 14, the inner wall of the steel gas cylinder can be derusted.

[0033] See Figure 1-5 As shown, a pin is provided in the mounting base 7, and the first electric push rod 6 is rotatably sleeved on the pin. The first electric push rod 6 can be conveniently rotatably mounted on the mounting base 7, avoiding the problem of motion interference and ensuring the normal operation of the steel gas cylinder inner wall rust removal device.

[0034] See Figure 1-5 , both ends of the opposite side of the fixing member 4 and the clamping member 5 are provided with a slide groove 8, a slider 9 is slidably inserted in the slide groove 8, the mounting seat 7 is fixedly connected to the slider 9, and a second electric push rod 10 is fixedly installed on both sides of the fixing member 4 and the clamping member 5, and the driving end of the second electric push rod 10 is fixedly connected to the slider 9.

[0035] During specific implementation, based on the above implementation, if it is necessary to remove rust from steel gas cylinders of different diameters, the second electric push rod 10 can be opened, so that the driving end of the second electric push rod 10 can be extended and retracted to drive the slider 9 to slide in the slide groove 8, and the distance between the first electric push rod 6 and the end of the clamping member 5 can be adjusted, so that steel gas cylinders with different curvatures can be positioned, thereby improving the scope of application.

[0036] See Figure 1-5 A sliding opening 13 is formed on one side of the U-shaped box 2, communicating with the interior of the box 2. The positioning bar 3 slides within the sliding opening 13. This facilitates the normal sliding of the positioning bar 3 within the U-shaped box 2, avoiding motion interference and further ensuring the proper operation of the steel gas cylinder inner wall rust removal device. It should be noted that the direction of the sliding opening 13 is the same as the direction in which the screw rod 11 is set, so that the positioning bar 3 can only slide in the direction in which the sliding opening 13 is set.

[0037] In addition, the rust removal component 14 usually includes a motor, a grinding part, a mounting plate, etc. The mounting plate can install the motor and the grinding part, and then the motor and the grinding part are connected by transmission. The grinding part is inserted into the steel gas cylinder to be derusted. After being accommodated, the motor is turned on to rotate the grinding part and grind the rust stains on the inner wall of the gas cylinder to achieve the rust removal effect. Since the rust removal component 14 is a prior art, it will not be explained in detail in this manual.

[0038] Working principle: When in use, first place the steel gas cylinder to be derusted in the U-shaped box 2 and between the two clamping members 5, then turn on the motor 12 to rotate the screw rod 11, so that the two positioning bars 3 drive the two fixing members 4 and the clamping member 5 to approach each other until they are against the steel gas cylinder to be derusted, then turn on the first electric push rod 6 to extend the driving end of the first electric push rod 6. Since the clamping member 5 is made of a deformable material, the driving end of the first electric push rod 6 can push the clamping member 5 to deform and bend and adhere to the surface of the gas cylinder, so that the gas cylinder can be completely wrapped, thereby improving the positioning effect of the gas cylinder and avoiding safety problems such as shaking when derusting the gas cylinder. Finally, with the rust removal component 14, the inner wall of the steel gas cylinder can be derusted;

[0039] In addition, if it is necessary to remove rust from steel gas cylinders of different diameters, the second electric push rod 10 can be opened, so that the driving end of the second electric push rod 10 can be extended and retracted to drive the slider 9 to slide in the slide groove 8. The distance between the first electric push rod 6 and the end of the clamping member 5 can be adjusted, and steel gas cylinders with different curvatures can be positioned, thereby improving the scope of application.
