Description

Technical Field

[0001] This application relates to the technical field of working equipment, and in particular, to a tooling for anti-electrochemical corrosion treatment of the surface of steel pipes. Background Art

[0002] There are many ways to anti-corrosion treat steel pipes. One of the more common methods is to coat the inner and outer walls of the steel pipes with acid and alkali resistant grease. The existing working equipment for coating is to suspend the steel pipes and then immerse them in the paint. Since the steel pipes are in contact with the hoisting equipment, the coated parts at the contact areas are significantly less than those at the exposed other parts. To ensure the uniformity of the anti-corrosion coating, manual touch-up is required at these places, which not only increases the working cost but also has a relatively low processing efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a tooling for anti-electrochemical corrosion treatment of the surface of steel pipes with higher efficiency.

The two ends of the concave part are inclined parts, and there are straight parts at the ends of the inclined parts. Between the opposite ends of the two straight parts is a sinking part. A plurality of baffle plates are fixedly connected to the outer surface of the conveyor belt, which is suitable for pushing the steel pipes to move together with the conveyor belt. Compared with the hoisting equipment, it will have a higher material throughput efficiency.

[0005] As a preference, the conveyor belt includes a belt body. The outer surface of the belt body has two outer belt edges, and the extending directions of the two outer belt edges are both parallel to the extending direction of the belt body. The baffle plates are fixedly connected to the outer surface of the belt body and are located between the two outer belt edges to reduce the shaking of the steel pipes.

[0006] As a preference, the plane where the baffle plates are located is perpendicular to the moving direction of the conveyor belt, and each baffle plate is provided with a liquid drainage hole to avoid the baffle plates hindering the liquid drainage inside the steel pipes.

[0007] As a preference, the inner surface of the belt body has an inner belt edge, and the extending direction of the inner belt edge is parallel to the extending direction of the belt body and deforms synchronously with the belt body.

[0008] Preferably, the transmission roller comprises a roller, the cylindrical side surface of the roller contacts the inner surface or the outer surface of the belt body, the end face of the roller contacts the side surface of the inner belt edge or the outer belt edge, and the end face of the roller has an end shaft suitable for passing through the axial hole of the side wall of the liquid storage tank and connecting with the output end of the driver, thereby obtaining rotational power.

[0011] As a preference, a liquid discharge end is provided at the bottom of the liquid collecting plate, and a bracket is fixedly connected to the bottom surface of the liquid collecting plate to maintain the stability of the entire processing tooling.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By designing a conveyor belt structure that can be partially immersed in liquid paint, the conveyor belt has the function of attaching the paint to the steel pipe.

[0027] The terms "comprising" and "having" in the description and claims of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0028] Such as Figures 1-8 The anti-electrochemical corrosion treatment tooling for the steel pipe surface as shown includes a liquid storage tank 1 for storing liquid paint. The liquid paint usually uses acid- and alkali-resistant grease. The liquid storage tank 1 includes a pair of side sealing plates 120. The two side sealing plates 120 are parallel to each other and symmetric about the vertical plane. A liquid retaining plate 110 is connected between the two side sealing plates 120. The main part of the liquid retaining plate 110 is horizontal and fixedly connected to the bottom surface of the side sealing plate 120. The two ends of the horizontal part of the liquid retaining plate 110 are bent upward to form vertical parts and are fixedly connected to the side surfaces of the side sealing plate 120. In this way, the entire liquid storage tank 1 is only open at the upper end, which is convenient for containing the liquid paint with anti-electrochemical corrosion. Through holes 112 are also provided at the tops of both ends of the liquid retaining plate 110, through which the steel pipe can pass. One of the two through holes 112 is for the steel pipe to enter the liquid storage tank 1; the other is for the treated steel pipe to exit the liquid storage tank 1. A liquid discharge end 111 is provided at the bottom of the liquid retaining plate 110. The liquid discharge end 111 extends downward and is used to discharge the liquid paint contaminated in the liquid storage tank 1 due to long-term use. Usually, a valve body structure is also configured on the liquid discharge end 111 to control the on-off state of the internal channel of the liquid discharge end 111. A bracket 2 is fixedly connected to the bottom surface of the liquid retaining plate 110. The bracket 2 is generally fixedly arranged on the ground to ensure the stability of the entire tooling.

[0029] The top surface of the side seal plate 120 and the top surfaces of both ends of the liquid retaining plate 110 are fixedly connected together with a limit frame 103. A dust cover 6 is movably connected within the limit frame 103, which is used to shield the open end at the top of the liquid storage tank 1, reduce dust pollution to the liquid paint, and at the same time reduce the probability of the liquid paint splashing outside the liquid storage tank 1. A chute 104 extending inwards is provided on one side of the limit frame 103. The dust cover 6 includes a horizontal cover plate 601, which can inhibit the end of the steel pipe in the liquid storage tank 1 from tilting up and make the steel pipe return to the horizontal position. The side surface of the cover plate 601 has sliding plates 602. Usually, there are also a pair of sliding plates 602, which are located on the opposite side surfaces of the cover plate 601 and just cooperate with the chute 104 to form a sliding pair. That is to say, the cover plate 601 is suitable for being inserted into the limit frame 103. The cover plate 601 also has a limit plate 603 on the side surface perpendicular to the sliding plate 602. The limit plate 603 protrudes from the upper surface of the cover plate 601 and is used to limit the maximum insertion depth of the cover plate 601. A relief groove 604 is provided on the limit plate 603 to facilitate the staff's fingers to buckle in and pull out the entire dust cover 6. Subsequently, the upper end of the liquid storage tank 1 is opened, and liquid paint can be replenished in the liquid storage tank 1 first. The cover plate 601 is usually made of a transparent material, such as acrylic board or tempered glass, to facilitate the staff to observe whether the liquid level height of the remaining paint in the liquid storage tank 1 is sufficient to completely submerge the entering steel pipe.

[0030] A conveyor belt 5 is arranged in the liquid storage tank 1 for moving the steel pipe in the liquid storage tank 1. A driver 3 is arranged outside the liquid storage tank 1. The driver 3 includes a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is the output end of the entire driver 3. The driver 3 drives the conveyor belt 5 through a transmission roller 4. Under the constraint of the transmission roller 4, a concave portion 510 is formed on the upper part of the conveyor belt 5, which needs to be submerged below the liquid level of the liquid in the liquid storage tank 1 to ensure that the steel pipe located on the concave portion 510 can also be completely submerged below the liquid level of the paint, so that any part of the inner and outer walls of the steel pipe can be covered with paint. The two ends of the concave portion 510 are inclined portions 520 for making the steel pipe inclined upwards or downwards. There is also a flat portion 530 at the end of the inclined portion 520. The steel pipe located on the flat portion 530 will be parallel to the length direction of the liquid storage tank 1 to facilitate entering or leaving the interior of the liquid storage tank 1. The outer surface of the flat portion 530 is usually slightly higher than the lowest point of the through hole 112 on the liquid storage tank 1. Therefore, the two flat portions 530 do not need to be submerged below the liquid level of the paint. That is to say, the liquid level of the paint will be lower than the lowest point of the through hole 112, which can effectively prevent the liquid paint from overflowing. The part between the opposite ends of the two flat portions 530 is a sinking portion 540, that is, the lower half of the entire conveyor belt 5. The upper half of the conveyor belt 5 located above will contact the steel pipe. The upper and lower parts of the conveyor belt 5 are always flowing because they are only named according to different positions. When the upper half of the conveyor belt 5 rotates to the lower part, it will become the lower half.

[0031] The specific structure of the conveyor belt 5 includes a belt body 501 connected at both ends. The outer surface of the belt body 501 has two outer belt edges 504, which protrude significantly from the outer surface of the belt body 501 and enclose and are close to the two edges of the belt body 501. The extending directions of the two outer belt edges 504 are parallel to the extending direction of the belt body 501. The inner surface of the belt body 501 has an inner belt edge 503, which protrudes significantly from the inner surface of the belt body 501. The inner belt edge 503 can be one, and in this embodiment, two are provided. The extending direction of each inner belt edge 503 is also parallel to the extending direction of the belt body 501. The specific structure of the driving roller 4 includes a roller 401. The cylindrical side surface of the roller 401 contacts the inner surface or the outer surface of the belt body 501, and the end surface of the roller 401 contacts the side surface of the inner belt edge 503 or the outer belt edge 504. In fact, the roller 401 located outside the belt body 501 will contact the outer surface of the belt body 501 and the outer belt edge 504; the roller 401 located inside the belt body 501 will contact the inner surface of the belt body 501 and the inner belt edge 503, which can effectively inhibit the crosstalk of the conveyor belt 5 and improve the movement stability of the conveyor belt 5. The end surface of the roller 401 has an end shaft 402 for passing through the shaft hole 121 on the side wall of the liquid storage tank 1 and connecting to the output end of the driver 3. In fact, the shaft hole 121 starts on the side sealing plate 120 and penetrates the inner and outer surfaces of the side sealing plate 120. Usually, a bearing structure is also provided in the shaft hole 121 to form a rotating pair with the end shaft 402, which can effectively improve the working stability and service life of the driving roller 4.

[0032] A number of baffles 502 are fixedly connected to the outer surface of the conveyor belt 5. Usually, these baffles 502 are arranged equidistantly along the circumference of the conveyor belt 5, and the distance between adjacent baffles 502 is slightly larger than the length of a single steel pipe. The plane where the baffles 502 are located is perpendicular to the moving direction of the conveyor belt 5, and can push the steel pipe to move together with the conveyor belt 5. In fact, the baffles 502 are fixedly connected to the outer surface of the belt body 501 and are located between the two outer belt edges 504. The outer belt edges 504 can prevent the steel pipe from rolling on the belt body 501 and avoid rubbing between the steel pipe and the side sealing plate 120. Each baffle 502 is provided with a liquid discharge hole 505, and the liquid discharge hole 505 penetrates the two end faces of the baffle 502. The excess liquid paint entering the steel pipe will be discharged from the liquid discharge hole 505. In this way, the baffle 502 can block the steel pipe body without blocking the flowing liquid paint, which is convenient for the steel pipe to empty the excess paint inside.

[0033] Working principle: When in use, the steel pipe that needs to be treated with anti-electrocorrosion is inserted into a through hole 112 of the liquid storage tank 1, and is received by the nearest straight portion 530 of the conveyor belt 5, and continues to enter the liquid storage tank 1 following the straight portion 530. When the center of gravity of the steel pipe passes the transition between the straight portion 530 and the inclined portion 520, the suspended end of the steel pipe will tilt downward and then immerse in the liquid paint, and continue to move until it enters the concave portion 510. The steel pipe will be completely immersed in the liquid paint. At this time, the baffle 502 on the conveyor belt 5 will press against the end of the steel pipe and push the steel pipe to continue moving forward until the end of the steel pipe is lifted by the next inclined portion 520. The end of the steel pipe will slowly protrude from the liquid surface, and the liquid paint inside the steel pipe will It is discharged under the action of its own gravity. When the raised end of the steel pipe presses against the cover plate 601 or the center of gravity of the steel pipe passes the transition between the next inclined portion 520 and the next straight portion 530, the steel pipe will return to the horizontal state from the inclined state, and the last liquid coating inside will be thrown out through the drainage hole 505 of the baffle 502. The steel pipe coated with the anti-corrosion coating is finally discharged from another through hole 112 of the liquid storage tank 1 under the push of the straight portion 530, thus completing the anti-corrosion treatment of the steel pipe surface. Since the steel pipe will be completely immersed in the coating, and the coating adhered to the conveyor belt 5 can be attached to the side of the steel pipe opposite to the conveyor belt 5, the discharged steel pipe does not need to be re-coated.
