Description

Technical Field

[0001] This utility model relates to the field of steel structure heat treatment technology, and in particular to an anti-oxidation treatment device for steel structure materials before heat treatment. Background Technology

[0002] Currently, when steel structure materials undergo anti-oxidation treatment before heat treatment, horizontal clamping spraying equipment is often used. This type of equipment typically includes a horizontal operating table, fixed clamps on the operating table, a spray nozzle installed on one side of the operating table, and a drive component that drives the steel structure to rotate horizontally. During operation, the steel structure is placed horizontally on the operating table and fixed by the clamps. The spray nozzle sprays anti-oxidation coating onto the surface of the steel structure, while the drive component drives the steel structure to rotate horizontally to complete the spraying operation.

[0003] However, during use, the contact points between the steel structure and the horizontal operating table and clamping components of this horizontal clamping spraying equipment are prone to obstruction, preventing the spray head from effectively spraying the obstructed areas and creating spraying dead corners. Subsequent manual respraying of these dead corner areas not only increases the number of operation steps and reduces processing efficiency, but also makes it difficult to maintain the same coating thickness and uniformity as other areas. This results in uneven overall quality of the anti-oxidation coating on the steel structure surface, which in turn makes areas with weak or missing coatings prone to oxidation during subsequent heat treatment, affecting the mechanical properties and service life of the steel structure. Utility Model Content

[0004] The present invention aims to solve the problems of spraying dead corners and uneven spraying that easily occur when steel structure materials are subjected to anti-oxidation treatment before heat treatment.

[0005] Therefore, the purpose of this utility model is to propose an anti-oxidation treatment device for steel structure materials before heat treatment. The device uses the contact head and rotating head of the assembly component to clamp the steel structure, pull the component to make the placement sleeve stand up, and the L-shaped support platform and the spraying nozzle with solenoid valve cooperate with the rotation of the steel structure to achieve spraying. This solution solves the problem of spraying dead corners caused by the contact between the steel structure and the support component in the horizontal spraying equipment in the background technology. It eliminates the need for manual touch-up spraying, ensures the uniformity of the coating, avoids local oxidation during subsequent heat treatment, and protects the mechanical properties and service life of the steel structure.

[0006] To achieve the above objectives, this utility model proposes an anti-oxidation treatment device for steel structure materials before heat treatment, including a fixed platform, an operating platform, a placement sleeve, a support frame, an assembly assembly, a pulling assembly, and a spraying assembly. The operating platform is fixedly connected to the top of the fixed platform, the placement sleeve is embedded in the top of the operating platform, and the support frame is fixedly connected to the ends of the fixed platform and the operating platform. The assembly assembly includes a first support head, a first driving device, a contact head, a second support head, a second driving device, and a rotating head. The first and second support heads are respectively fixedly connected to the two ends of the placement sleeve. The first driving device is installed at the end of the first support head, and its output end passes through the first support head and is rotatably connected to the end of the contact head. The second driving device is installed at the end of the second support head, and its output end passes through the second support head and is fixedly connected to one end of the rotating head. The outer wall of the second support head is rotatably connected to the inner wall of the support frame via a connector. The pulling assembly is installed on the support frame and connected to the first support head. The spraying assembly is installed on the top of the operating platform.

[0007] This utility model discloses an anti-oxidation treatment device for steel structure materials before heat treatment. A cylindrical steel structure is placed into a placement sleeve on the top of an operating table. The inclined surface between the top of the operating table and the placement sleeve facilitates positioning. A placement groove matching the placement sleeve is provided on the top of the operating table. The inner wall of the placement sleeve is covered with a protective film. Activating the first drive device moves the contact head, causing it to engage with the rotating head at the second support head to clamp the cylindrical steel structure. Subsequently, activating the third drive device rotates the winding roller, which winds up the connecting rope and pulls the first support head. A first support head and a second support head are fixed to a placement sleeve plate, with the second support head rotatably connected to the inner wall of the support frame. The placement sleeve plate rises around a pivot point as the first and second support heads move. Then, the pump is activated to extract anti-oxidation coating from the storage housing. The coating is transported via a connecting pipe to an L-shaped support platform fixed to the second support head. The nozzle with a solenoid valve at the bottom of the support platform is opened to spray the coating. Simultaneously, the second drive device is activated to rotate the rotating head, which in turn rotates the clamped cylindrical steel structure synchronously, achieving uniform spraying of the cylindrical steel structure's circumference. In the background technology, when horizontal equipment processes cylindrical steel structures, the contact between the cylindrical steel structure and the support components creates spraying dead angles, the friction with the support surface is high, easily scratching the surface, and the coating easily accumulates, leading to uneven coating. This equipment avoids contact and obstruction by standing the cylindrical steel structure upright, reduces friction and scratches with a protective film, and ensures uniform coating by rotating and using equally spaced nozzles. It eliminates the need for manual touch-ups, prevents localized oxidation of the cylindrical steel structure during subsequent heat treatment, and protects its mechanical properties.

[0008] In addition, the anti-oxidation treatment equipment for steel structure materials before heat treatment proposed in this utility model may also have the following additional technical features: Specifically, the pulling assembly includes a third drive device, a take-up roller, and a connecting rope. The third drive device is installed on the top side of the support frame, the take-up roller is rotatably connected to the inner wall of the support frame, and one end of the take-up roller is fixedly connected to the output end of the third drive device. One end of the connecting rope is fixedly connected to the first support head, and the other end of the connecting rope is sleeved on the take-up roller.

[0009] Specifically, the spraying assembly includes a storage housing, a pump body, a support platform, spray nozzles, and connecting pipes. The storage housing and the pump body are both installed on the top of the operating table and located on the side where the sleeve is placed. The input end of the pump body is connected to the outer wall of the storage housing. One end of the support platform is fixedly connected to a second support head. Multiple spray nozzles are fixedly connected at equal intervals to the bottom of the support platform. A connecting pipe is provided between the pump body and the support platform, and they are connected through the connecting pipe.

[0010] Specifically, the top edge of the operating table is inclined to the placement of the sleeve plate.

[0011] Specifically, the top of the operating table is provided with a placement slot that matches the placement sleeve, and the inner wall of the placement sleeve is covered with a protective film.

[0012] Specifically, the support platform has an L-shaped structure, and multiple nozzles are equipped with solenoid valves.

[0013] This invention relates to an anti-oxidation treatment device for steel structure materials before heat treatment. It provides a reliable carrier during steel structure flipping, preventing deformation under stress. The flipping action is smooth, and the flipping angle can be flexibly controlled to adapt to spraying requirements. This invention effectively prevents nozzle position deviation during spraying, ensuring spraying accuracy and achieving uniform spraying on the steel structure surface. It solves the problem of spraying dead corners caused by obstruction between the steel structure and supporting components, eliminating the need for manual touch-ups and ensuring the uniformity of the anti-oxidation coating on the steel structure surface. This prevents oxidation in areas with weak or missing coatings during subsequent heat treatment, ensuring the mechanical properties and service life of the steel structure. Simultaneously, the spraying assembly of this invention can stably deliver paint, preventing waste and pollution caused by paint leakage. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0017] The following description, in conjunction with the accompanying drawings, describes an anti-oxidation treatment device for steel structure materials before heat treatment according to an embodiment of the present invention.

[0018] like Figures 1-4 As shown, the anti-oxidation treatment equipment for steel structure materials before heat treatment in this embodiment of the present invention may include a fixed platform 1, an operating platform 2, a placement sleeve 3, a support frame 4, an assembly assembly 5, a pulling assembly 6, and a spraying assembly 7.

[0019] The control panel 2 is fixedly connected to the top of the fixed platform 1, the placement sleeve 3 is embedded in the top of the control panel 2, and the support frame 4 is fixedly connected to the ends of the fixed platform 1 and the control panel 2.

[0020] It should be noted that the fixed connection between the fixed platform 1 and the operating platform 2 described in this embodiment can build a stable equipment foundation and avoid the impact of equipment shaking on processing accuracy during subsequent steel structure clamping, flipping and spraying. The design of the placement sleeve 3 embedded in the operating platform 2 can play a role in pre-positioning the steel structure and prevent the steel structure from shifting when placed. The support frame 4 provides a reliable carrier for the installation of the pulling component 6 and the flipping action of the placement sleeve 3, avoiding deformation under stress.

[0021] Assembly component 5 includes a first support head 51, a first drive device 52, an abutment head 53, a second support head 54, a second drive device 55, and a rotating head 56. The first support head 51 and the second support head 54 are respectively fixedly connected to the two ends of the placement sleeve 3. The first drive device 52 is installed at the end of the first support head 51, and the output end of the first drive device 52 passes through the first support head 51 and is rotatably connected to the end of the abutment head 53. The second drive device 55 is installed at the end of the second support head 54, and the output end of the second drive device 55 passes through the second support head 54 and is fixedly connected to one end of the rotating head 56. The outer wall of the second support head 54 is rotatably connected to the inner wall of the support frame 4 through a connector.

[0022] It should be noted that the fixed connection between the first support head 51 and the second support head 54 described in this embodiment and the placement sleeve 3 forms an integrated structure, ensuring synchronous action during flipping and preventing the steel structure from loosening. The first drive device 52 is a hydraulic cylinder, and the output end of the first drive device 52 is rotatably connected to the contact head 53, which allows the contact head 53 to rotate with the steel structure, preventing friction and scratching of the steel structure surface, while maintaining stable clamping. The second drive device 55 is a drive motor, and the fixed connection between the second drive device 55 and the rotating head 56 can directly transmit power to drive the steel structure to rotate, ensuring uniform spraying. The rotatable connection between the second support head 54 and the support frame 4 provides a fulcrum for the flipping of the placement sleeve 3, making the flipping action smooth and allowing flexible control of the flipping angle to adapt to spraying requirements.

[0023] The pulling component 6 is mounted on the support frame 4 and connected to the first support head 51, and the spraying component 7 is mounted on the top of the operating table 2.

[0024] It should be noted that the pulling component 6 described in this embodiment is installed on the support frame 4 and connected to the first support head 51. It can stably transmit the pulling force with the strength of the support frame 4, avoid the component from shifting when pulling, and ensure that the placement sleeve 3 is stably erected. The spraying component 7 is installed on the top of the operating table 2, which can shorten the paint delivery distance and reduce paint loss. At the same time, the stable structure of the operating table 2 can provide fixed support for the spraying component 7, prevent the nozzle 74 from shifting during spraying, and ensure spraying accuracy.

[0025] Specifically, the steel structure to be processed is placed into the placement sleeve 3 embedded in the top of the operating table 2. The first driving device 52 is a hydraulic cylinder, which is installed at the end of the first support head 51. After the first driving device 52 is started, its output end passes through the first support head 51, driving the contact head 53 to move towards one end of the steel structure, so that the other end of the steel structure abuts against the rotating head 56 at the second support head 54, thus achieving a stable clamping of the steel structure. The contact head 53 is rotatably connected to the output end of the first driving device 52, which can prevent scratching the surface of the steel structure as it rotates. Then, the pulling component 6 installed on the support frame 4 is started. The pulling component 6 stably transmits the pulling force with the structural strength of the support frame 4, driving the component connected to the first support head 51 to move. Since the first support head 51 and the second support head 54 are respectively fixedly connected to the placement sleeve 3, and the outer wall of the second support head 54 is rotatably connected to the inner wall of the support frame 4 through the connector, the placement sleeve 3 moves with the first support head 51 and the second support head 54. The head 54 moves around the rotational connection point between the second support head 54 and the support frame 4, then the spraying assembly 7 installed on the top of the operating table 2 is activated. The operating table 2 provides stable support for the spraying assembly 7, preventing the nozzle 74 on the spraying assembly 7 from shifting position. At the same time, the spraying assembly 7 can shorten the paint delivery distance to reduce paint loss. After the paint is delivered to the corresponding spraying position, the second drive device 55 installed at the end of the second support head 54 is activated. The second drive device 55 is a drive motor, whose output end passes through the second support head 54 and drives the rotating head 56 to rotate. The rotating head 56 then drives the clamped steel structure to rotate synchronously, realizing uniform spraying on the surface of the steel structure. This process solves the problem of spraying dead corners caused by the contact between the steel structure and the support components in the horizontal spraying equipment in the background technology. There is no need for manual touch-up spraying, which ensures the uniformity of the anti-oxidation coating on the surface of the steel structure and avoids oxidation in areas with weak or missing coatings during subsequent heat treatment, thus ensuring the mechanical properties and service life of the steel structure.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, the pulling assembly 6 includes a third drive device 61, a take-up roller 62, and a connecting rope 63. The third drive device 61 is installed on the top of one side of the support frame 4. The take-up roller 62 is rotatably connected to the inner wall of the support frame 4, and one end of the take-up roller 62 is fixedly connected to the output end of the third drive device 61. One end of the connecting rope 63 is fixedly connected to the first support head 51, and the other end of the connecting rope 63 is sleeved on the take-up roller 62.

[0027] It should be noted that the third driving device 61 described in this embodiment is a drive motor. The third driving device 61 is installed on the top side of the support frame 4, which can provide a stable driving force for the take-up roller 62 without occupying the operating space above the operating table 2, thus avoiding interference with the placement and clamping of the steel structure. The take-up roller 62 is rotatably connected to the inner wall of the support frame 4, which can ensure coaxiality during rotation, prevent the connecting rope 63 from deviating or tangling when it is wound, and ensure uniform tension transmission. One end of the connecting rope 63 is fixed to the first support head 51, and the other end is sleeved on the take-up roller 62, which can realize the direct transmission of tension. The sleeved connection method facilitates the replacement and maintenance of the connecting rope 63. At the same time, the stability of the fixed connection can prevent the connecting rope 63 from falling off during the pulling process, ensuring the reliable execution of the flipping action of the placement sleeve 3.

[0028] Specifically, when it is necessary to lift the placement sleeve 3, the third drive device 61 is activated. The output end of the third drive device 61 drives the take-up roller 62 to rotate on the inner wall of the support frame 4. During the rotation of the take-up roller 62, the connecting rope 63 is wound up. The connecting rope 63 generates tension during winding and pulls the first support head 51. Since the first support head 51 is fixed to one end of the placement sleeve 3 and the second support head 54 is rotatably connected to the inner wall of the support frame 4, the placement sleeve 3 is lifted up around the rotation point of the second support head 54 and the support frame 4 as the first support head 51 moves, so that the steel structure is separated from the surface of the operating table 2, avoiding contact between the steel structure and the operating table 2 to form an obstruction. This solves the problem of spraying dead angles caused by the obstruction of the support components in the horizontal spraying equipment in the background art.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, the spraying assembly 7 includes a storage housing 71, a pump body 72, a support platform 73, a nozzle 74, and a connecting pipe 75. The storage housing 71 and the pump body 72 are both installed on the top of the operating table 2 and located on the side where the sleeve plate 3 is placed. The input end of the pump body 72 is connected to the outer wall of the storage housing 71. One end of the support platform 73 is fixedly connected to the second support head 54. Multiple nozzles 74 are fixedly connected at equal intervals to the bottom of the support platform 73. A connecting pipe 75 is provided between the pump body 72 and the support platform 73, and they are connected through the connecting pipe 75.

[0030] It should be noted that the storage housing 71 and pump body 72 described in this embodiment are installed on the top of the operating table 2 and located on one side of the placement sleeve 3. This can shorten the paint conveying path, reduce paint residue and loss during the conveying process, and the proximity to the placement sleeve 3 facilitates timely paint replenishment, improving work efficiency. The support platform 73 is fixed on the second support head 54 and can move synchronously with the second support head 54 and the placement sleeve 3, ensuring that the nozzle 74 always maintains an appropriate distance from the erected steel structure, avoiding changes in spraying distance from affecting the coating thickness. Multiple nozzles 74 are evenly distributed, which can cover the circumference of the steel structure, ensuring uniform spraying range. The connecting pipe 75 connects the pump body 72 and the support platform 73, which can stably convey paint and prevent waste and pollution caused by paint leakage.

[0031] Specifically, before spraying, the storage housing 71 stores the anti-oxidation coating. The pump 72 is started, and the pump 72 input end draws the coating from the storage housing 71. The coating is then transported to the support platform 73 fixed on the second support head 54 through the connecting pipe 75. The coating is then sprayed out by the nozzles 74 at equal intervals at the bottom of the support platform 73. Since the support platform 73 is erected synchronously with the second support head 54 and the placement sleeve 3, the nozzles 74 can face the surface of the steel structure. With the help of the second drive device 55 to drive the steel structure to rotate, the coating can evenly cover the circumference of the steel structure. There is no need to manually adjust the position of the nozzles 74, which avoids the problem of local spraying incomplete coverage caused by the fixed nozzles 74 when spraying horizontally. This solves the problems of spraying dead corners and uneven coating in the background technology.

[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, the top edge of the operating table 2 is inclined to the placement of the sleeve plate 3.

[0033] Specifically, after the steel structure is placed on the operating table 2, it can easily roll into the interior of the placement sleeve 3 under the action of the inclined surface.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, the top of the operating table 2 is provided with a placement slot that matches the placement sleeve 3, and the inner wall of the placement sleeve 3 is covered with a protective film.

[0035] It should be noted that the placement groove on the top of the operating table 2, which matches the placement sleeve 3, as described in this embodiment, can accurately position the placement sleeve 3, preventing it from shifting on the operating table 2 and ensuring the accuracy of subsequent steel structure clamping and flipping operations. The protective film on the inner wall of the placement sleeve 3 can prevent scratches caused by direct friction between the steel structure surface and the inner wall of the placement sleeve 3 during the insertion, clamping, and rotation of the steel structure, protecting the surface quality of the steel structure. At the same time, the protective film can also reduce the adhesion of paint to the inner wall of the placement sleeve 3, making subsequent cleaning easier and reducing the maintenance difficulty of the placement sleeve 3.

[0036] In one embodiment of this utility model, such as Figures 1-4 As shown, the support platform 73 has an L-shaped structure, and multiple nozzles 74 are equipped with solenoid valves.

[0037] It should be noted that the support platform 73 described in this embodiment has an L-shaped structure, which can be stably fixed on the second support head 54 and allow the nozzle 74 to extend downward to the appropriate height of the steel structure. This avoids the support platform 73 itself obstructing the spraying range of the nozzle 74, ensuring that the paint can be directly sprayed onto the surface of the steel structure. The solenoid valves installed on the multiple nozzles 74 can independently control the start and stop of spraying and the paint flow of each nozzle 74. The spraying range can be adjusted according to the diameter or length of the steel structure to avoid unnecessary paint waste. At the same time, a faulty nozzle 74 can be flexibly shut down during the spraying process without affecting the continuation of the overall spraying operation, thus improving the fault tolerance and flexibility of the equipment.

[0038] It should be understood that when the steel structure is rotated for spraying while upright, the circumference of the steel structure is more evenly affected by gravity. After spraying, the paint can be evenly distributed along the circumference, avoiding the local accumulation and sagging problems caused by the accumulation of paint on the lower surface of the steel structure due to gravity when spraying horizontally. Especially for anti-oxidation paints with slightly higher viscosity, it can effectively ensure the uniformity of the coating thickness and avoid the difference in anti-oxidation performance caused by uneven coating during subsequent heat treatment. In particular, it avoids the problem of increased friction between the steel structure and the inner wall of the sleeve 3 under the action of gravity when the steel structure is operated horizontally.

[0039] In summary, the anti-oxidation treatment equipment for steel structure materials before heat treatment in this embodiment of the present invention places the cylindrical steel structure into the placement sleeve 3 on the top of the operating table 2. The inclined surface between the top of the operating table 2 and the placement sleeve 3 facilitates positioning. The top of the operating table 2 has a placement groove matching the placement sleeve 3. The inner wall of the placement sleeve 3 is covered with a protective film. The first driving device 52 is activated to move the contact head 53, causing the contact head 53 to engage with the rotating head 56 at the second support head 54 to clamp the cylindrical steel structure. Subsequently, the third driving device 61 is activated to rotate the winding roller 62. The winding roller 62 winds up the connecting rope 63 and pulls the first support head 51. A support head 51 and a second support head 54 are respectively fixed to the placement sleeve 3, and the second support head 54 is rotatably connected to the inner wall of the support frame 4. The placement sleeve 3 is erected around the rotation point as the first support head 51 and the second support head 54 move. Then, the pump body 72 is started to draw anti-oxidation coating from the storage shell 71. The coating is transported to the L-shaped support platform 73 fixed to the second support head 54 through the connecting pipe 75. The nozzle 74 with a solenoid valve at the bottom of the support platform 73 is opened to spray out the coating. At the same time, the second drive device 55 is started to drive the rotating head 56 to rotate. The rotating head 56 then drives the clamped columnar steel structure to rotate synchronously, so as to achieve uniform spraying on the circumferential surface of the columnar steel structure. In the background technology, when horizontal equipment processes columnar steel structures, the contact between the columnar steel structure and the supporting components creates spray dead angles, the friction with the supporting surface is high and easily scratches the surface, and the paint is easy to accumulate, resulting in uneven coating. This equipment avoids contact and obstruction by standing the columnar steel structure upright, the protective film reduces friction and scratches, and the rotating and equally spaced spray nozzles 74 ensure uniform coating. No manual touch-up spraying is required, and local oxidation of the columnar steel structure is avoided during subsequent heat treatment, thus ensuring its mechanical properties.

[0040] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
