Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing technology, specifically relating to hot-dip galvanizing drying equipment, and more particularly to drying equipment for hot-dip galvanizing. Background Technology

[0002] After hot-dip galvanizing, steel pipes need to be dried. During the drying process, the inner wall of the steel pipe also needs to be dried. This is especially important for long steel pipes (such as those exceeding 5 meters in length), as the fluid inside the pipe cannot be naturally discharged due to gravity when the pipe is placed horizontally.

[0003] In existing technologies, drying equipment uses inclined brackets to place steel pipes at an angle. However, in related technologies, the drying equipment is operated by opening a door on one side for feeding and unloading. This requires multiple people to work together to push the steel pipes onto the inclined brackets. Since the steel pipes are heavy (e.g., more than 100 kg), they are prone to backing up during the inclined feeding and unloading process, posing a safety hazard of being crushed.

[0004] Therefore, it is necessary to design a drying equipment for hot-dip galvanizing to solve the problem in the existing technology where the steel pipes tend to back up during the inclined feeding process due to their large weight.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one drying device for hot-dip galvanizing to solve the technical problem that steel pipes tend to back up during inclined feeding due to their large weight.

[0007] In a first aspect, embodiments of this disclosure provide a drying device for hot-dip galvanizing, comprising: a first bracket having a plurality of front-end pipe support slots; a second bracket having a rear-end pipe support slot corresponding to the front-end pipe support slots, wherein the support height of the rear-end pipe support slot is lower than the support height of the front-end pipe support slot, so that the steel pipe is inclined; and a locking component being vertically and vertically disposed on one side of the second bracket facing the loading port, i.e., the locking component descends and its top abuts against the bottom of the circumference of the steel pipe to allow the steel pipe to pass through, and the locking component rises to abut against the tail end of the steel pipe.

[0008] In one optional embodiment, the locking assembly includes a support frame and a T-shaped member. The T-shaped member is fixed on a second bracket, and the support frame is fitted onto the T-shaped member and adapted to slide upward or downward along the T-shaped member. A roller is rotatably connected to the support frame and adapted to roll about its own axis. The roller rotates to drive the steel pipe to move from the rear pipe support groove to the front pipe support groove. The roller separates from the steel pipe, causing the support frame to slide upward along the T-shaped member to abut against the end face of the tail end of the steel pipe.

[0009] In one optional embodiment, the support frame is provided with an elongated groove, the two side walls of which abut against the two sides of the T-shaped member; wherein, the support frame is adapted to slide along the elongated groove on the T-shaped member.

[0010] In one alternative embodiment, a spring is connected to the top surface of the long through groove, and the other end of the spring is connected to a T-shaped piece; wherein, the separation of the roller from the steel pipe causes the compressed spring to rebound, thereby driving the support frame to slide upward along the T-shaped piece and then abut against the end face of the tail end of the steel pipe.

[0011] In one alternative embodiment, the top surface of the T-shaped member is provided with a groove adapted to accommodate a compressed spring; wherein, when the steel pipe presses against the surface of the roller, the spring is compressed into the groove so that the top surface of the long groove abuts against the top surface of the T-shaped member.

[0012] Secondly, this disclosure also provides a drying device for hot-dip galvanizing, comprising: a drying hood having a feeding port, the feeding port being opposite to an exhaust port; a second bracket fixed to the inner wall of the drying hood on one side of the feeding port, the second bracket having a plurality of rear end pipe support grooves; and a locking assembly that is vertically movable on the side of the second bracket facing the feeding port, i.e., the locking assembly descends and its top abuts against the bottom of the circumference of the steel pipe to allow the steel pipe to pass through, and the locking assembly rises to abut against the tail end of the steel pipe.

[0013] In one optional embodiment, the locking assembly includes a support frame and a T-shaped member. The T-shaped member is fixed on a second bracket, and the support frame is fitted onto the T-shaped member and adapted to slide upward or downward along the T-shaped member. A roller is rotatably connected to the support frame and adapted to roll about its own axis. The roller rotates to drive the steel pipe to move from the rear pipe support groove to the front pipe support groove. The roller separates from the steel pipe, causing the support frame to slide upward along the T-shaped member to abut against the end face of the tail end of the steel pipe.

[0014] In one optional embodiment, the support frame is provided with an elongated groove, the two side walls of which abut against the two sides of the T-shaped member; wherein, the support frame is adapted to slide along the elongated groove on the T-shaped member.

[0015] In one alternative embodiment, a spring is connected to the top surface of the long through groove, and the other end of the spring is connected to a T-shaped piece; wherein, the separation of the roller from the steel pipe causes the compressed spring to rebound, thereby driving the support frame to slide upward along the T-shaped piece and then abut against the end face of the tail end of the steel pipe.

[0016] In one alternative embodiment, the top surface of the T-shaped member is provided with a groove adapted to accommodate a compressed spring; wherein, when the steel pipe presses against the surface of the roller, the spring is compressed into the groove so that the top surface of the long groove abuts against the top surface of the T-shaped member.

[0017] The beneficial effects of this utility model are that it provides a drying device for hot-dip galvanizing, which, by setting a locking component that can slide up and down, allows the steel pipe to be fed by using the locking component as a rolling fulcrum. The steel pipe can be tilted and pushed to achieve a rolling feeding effect. After the steel pipe no longer presses against the locking component, the locking component will slide upward to abut against the end face of the steel pipe to position it. This reduces the difficulty of feeding and avoids the phenomenon of the steel pipe retreating due to its large weight when feeding at an angle.

[0037] Research has found that after hot-dip galvanizing, steel pipes need to be dried. During the drying process, the inner wall of the steel pipe also needs to be dried. This is especially true for long steel pipes (such as those exceeding 5 meters in length), where the fluid on the inner wall cannot be naturally discharged due to gravity when the pipe is placed horizontally.

[0038] In existing technologies, drying equipment uses inclined brackets to place steel pipes at an angle. However, in related technologies, the drying equipment is operated by opening a door on one side for feeding and unloading. This requires multiple people to work together to push the steel pipes onto the inclined brackets. Since the steel pipes are heavy (e.g., more than 100 kg), they are prone to backing up during the inclined feeding and unloading process, posing a safety hazard of being crushed.

[0039] Therefore, it is necessary to design a drying equipment for hot-dip galvanizing to solve the problem in the existing technology where the steel pipes tend to back up during the inclined feeding process due to their large weight.

[0040] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] like Figures 1 to 3As shown, some embodiments provide a drying device for hot-dip galvanizing, including: a first bracket 2 and a second bracket 3, both the first bracket 2 and the second bracket 3 are provided with U-shaped pipe placement grooves. Specifically, the first bracket 2 is provided with a plurality of front pipe support grooves 21; the second bracket 3 is provided with a rear pipe support groove 31 corresponding to the front pipe support grooves 21, the support height of the rear pipe support groove 31 is lower than the support height of the front pipe support grooves 21, so that the steel pipe 5 is set at an inclination; the purpose of this design is to make the steel pipe 5 tilt to one side, so that the fluid inside the steel pipe 5 can flow out along the inclined surface, avoiding the phenomenon of residual liquid on the inner wall of the steel pipe 5.

[0044] To prevent the tilted steel pipe 5 from slipping and injuring workers during retraction, a locking component 4 is installed on the feeding side of the rear pipe support 31. The locking component 4 is vertically adjustable on the side of the second bracket 3 facing the feeding port 12, that is, on the side where the steel pipe 5 is fed. Specifically, the locking component 4 can be lowered so that its top abuts against the bottom of the circumference of the steel pipe 5 to allow it to pass, and it can also be raised to hold the tail end of the steel pipe 5. It should be noted that the steel pipe 5 needs to be lifted to a certain height using hoisting equipment, and then personnel are required to... Adjust the angle and press the first end of the steel pipe 5 onto the locking component 4. Then, using the locking component 4 as a fulcrum, apply a slight push to the steel pipe 5. At this time, the steel pipe 5 should be in an inclined state. The rolling of the top of the locking component 4 will achieve the effect of conveying the steel pipe 5 into the drying oven. When the tail end of the steel pipe 5 moves to the other side of the locking component 4, the material conveying is completed. At this time, the steel pipe 5 separates from the locking component 4. The locked component 4, which was pressed down, will spring back upward. One side of the locking component 4 will abut against the tail end of the steel pipe 5, thereby preventing the inclined steel pipe 5 from retreating.

[0045] like Figures 3 to 5 As shown, the locking assembly 4 is described in detail below. The locking assembly 4 includes a support frame 41 and a T-shaped member 45. The support frame 41 is provided with an elongated groove 43, and the two side walls of the elongated groove 43 abut against the two sides of the T-shaped member 45. The support frame 41 is adapted to slide along the elongated groove 43 on the T-shaped member 45. The T-shaped member 45 is fixed on the second bracket 3. The T-shaped member 45 consists of a horizontal plate and a vertical plate. One end of the horizontal plate is fixed to the second bracket 3, and the other end is fixed to the vertical plate. The support frame 41 is fitted onto the horizontal plate through the elongated groove 43.

[0046] A roller 42 is rotatably connected to the support frame 41. The roller 42 is rotatably connected to the top position of the support frame 41. The roller 42 is adapted to roll around its own axis. That is, after the steel pipe 46 is pressed on the roller 42, it can be conveyed forward with the rotation of the roller 42 from its position point. The roller 42 rotates to drive the steel pipe 5 to move from the rear pipe support groove 31 to the front pipe support groove 21. The roller 42 separates from the steel pipe 5, causing the support frame 41 to slide upward along the T-shaped piece 45 to abut against the end face of the tail end of the steel pipe 5.

[0047] In order to allow the support frame 41 to spring back to extend above the rear end tube tray 31 after the feeding is completed, a spring 44 is connected to the top surface of the long through slot 43, and the other end of the spring 44 is connected to the T-shaped piece 45. The separation of the roller 42 from the steel pipe 5 causes the compressed spring 44 to spring back, thereby driving the support frame 41 to slide upward along the T-shaped piece 45 and then abut against the end face of the tail end of the steel pipe 5. It should be noted that, without any other external force, the spring 44 will lift the support frame 41 to a height where the top surface exceeds the bottom surface of the rear end tube tray 31.

[0048] In addition, in order to allow the top surface of the long groove 43 to abut against the top surface of the T-shaped piece 45 when the spring 44 is compressed, a groove 46 is provided on the top surface of the T-shaped piece 45. The groove 46 is suitable for accommodating the compressed spring 44. That is, one end of the spring 44 is fixed to the top surface of the long groove 43, and the other end is fixed to the bottom surface of the groove 46. The lower half of the spring 44 exists in the groove 46. Therefore, when it is compressed to a certain extent, it will be completely contained in the groove 46. When the steel pipe 5 presses against the surface of the roller 42, the spring 44 is compressed into the groove 46 so that the top surface of the long groove 43 abuts against the top surface of the T-shaped piece 45.

[0049] Please see Figures 1 to 5 Some embodiments provide a drying device for hot-dip galvanizing, including: a drying hood 1, which is provided with a feeding port 12, the feeding port 12 being arranged opposite to an exhaust port 11; a second bracket 3, which is fixed on the inner wall of the drying hood 1 on one side of the feeding port 12, and the second bracket 3 is provided with a plurality of rear end pipe support grooves 31.

[0050] The locking component 4 is vertically adjustable and mounted on the side of the second bracket 3 facing the feed inlet 12. Specifically, the locking component 4 lowers so that its top abuts against the bottom of the circumference of the steel pipe 5, allowing the steel pipe 5 to pass through. It also rises to abut the tail end of the steel pipe 5. Additionally, the steel pipe 5 needs to be lifted to a certain height using hoisting equipment, and then its angle needs to be manually adjusted so that its head is pressed against the locking component 4. At this point, using the locking component 4 as a fulcrum, a slight pushing force is applied to the steel pipe 5, causing it to tilt. The rolling motion of the top of the locking component 4 conveys the steel pipe 5 into the drying oven. Once the tail end of the steel pipe 5 moves to the other side of the locking component 4, the feeding is complete. The steel pipe 5 then separates from the locking component 4. The lowered locking component 4 will then spring back upwards, with one side abutting against the tail end of the steel pipe 5, thus preventing the tilted steel pipe 5 from retracting.

[0051] like Figures 3 to 5As shown, the locking assembly 4 is described in detail below. The locking assembly 4 includes a support frame 41 and a T-shaped member 45. The support frame 41 is provided with an elongated groove 43, and the two side walls of the elongated groove 43 abut against the two sides of the T-shaped member 45. The support frame 41 is adapted to slide along the elongated groove 43 on the T-shaped member 45. The T-shaped member 45 is fixed on the second bracket 3. The T-shaped member 45 consists of a horizontal plate and a vertical plate. One end of the horizontal plate is fixed to the second bracket 3, and the other end is fixed to the vertical plate. The support frame 41 is fitted onto the horizontal plate through the elongated groove 43.

[0052] A roller 42 is rotatably connected to the support frame 41. The roller 42 is rotatably connected to the top position of the support frame 41. The roller 42 is adapted to roll around its own axis. That is, after the steel pipe 46 is pressed on the roller 42, it can be conveyed forward with the rotation of the roller 42 from its position point. The roller 42 rotates to drive the steel pipe 5 to move from the rear pipe support groove 31 to the front pipe support groove 21. The roller 42 separates from the steel pipe 5, causing the support frame 41 to slide upward along the T-shaped piece 45 to abut against the end face of the tail end of the steel pipe 5.

[0053] In order to allow the support frame 41 to spring back to extend above the rear end tube tray 31 after the feeding is completed, a spring 44 is connected to the top surface of the long through slot 43, and the other end of the spring 44 is connected to the T-shaped piece 45. The separation of the roller 42 from the steel pipe 5 causes the compressed spring 44 to spring back, thereby driving the support frame 41 to slide upward along the T-shaped piece 45 and then abut against the end face of the tail end of the steel pipe 5. It should be noted that, without any other external force, the spring 44 will lift the support frame 41 to a height where the top surface exceeds the bottom surface of the rear end tube tray 31.

[0054] In addition, in order to allow the top surface of the long groove 43 to abut against the top surface of the T-shaped piece 45 when the spring 44 is compressed, a groove 46 is provided on the top surface of the T-shaped piece 45. The groove 46 is suitable for accommodating the compressed spring 44. That is, one end of the spring 44 is fixed to the top surface of the long groove 43, and the other end is fixed to the bottom surface of the groove 46. The lower half of the spring 44 exists in the groove 46. Therefore, when it is compressed to a certain extent, it will be completely contained in the groove 46. When the steel pipe 5 presses against the surface of the roller 42, the spring 44 is compressed into the groove 46 so that the top surface of the long groove 43 abuts against the top surface of the T-shaped piece 45.

[0055] In summary, by setting up a locking component 4 that can slide up and down, the steel pipe 5 can be fed by using the locking component 4 as a rolling fulcrum and tilting the steel pipe 5 to achieve the rolling feeding effect. After the steel pipe no longer presses against the locking component 4, the locking component 4 will slide upward to hold the end face of the steel pipe 5 for positioning. This reduces the difficulty of feeding and avoids the phenomenon of the steel pipe 5 retreating due to its large weight when feeding at an angle.
