Description

Technical Field

[0001] This utility model relates to the field of steel formwork production, and in particular to an auxiliary treatment device for immersing bridge steel formwork in anti-rust oil. Background Technology

[0002] Steel formwork is a steel formwork used for concrete pouring and shaping. In addition to steel formwork, there are also wooden formwork, plywood formwork, etc. Steel formwork is widely used in construction projects because of its multiple uses and the aesthetically pleasing concrete pouring and shaping.

[0003] In the current production and processing of steel formwork, a rust-preventive oil immersion process is required for rust prevention. However, in the existing technology, after the steel formwork is immersed in rust-preventive oil, a lot of excess oil adheres to it. In the actual production process, it is necessary to wait for the excess oil to completely drip off before subsequent processing steps can be carried out. This waiting process is relatively long. Therefore, we need to consider how to make the excess oil drip off more quickly to improve processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary treatment device for immersing bridge steel formwork in anti-rust oil. In actual use, this device utilizes centrifugal force to allow excess oil to fall off quickly, reducing the time required to wait for excess oil to dissolve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bridge steel formwork rust-preventive oil immersion auxiliary treatment device includes a connecting plate. A motor is installed at the upper end of the connecting plate. The output shaft of the motor passes through the connecting plate and is fixedly connected to a drive box. A limit strip is provided below the drive box. Two hanging ear limit components are symmetrically installed at the lower end of the limit strip. A connecting ring is provided below the two limit strips. A roller is fixedly connected to the lower end of each limit strip. The lower end of each roller contacts the upper end of the connecting ring. The upper end of the connecting ring is fixedly connected to the outer wall of the connecting plate through multiple L-shaped mounting brackets. An adjustment drive mechanism for driving the limit strips to rotate is provided inside the drive box. Rotating bars are fixedly connected to both sides of the drive box. An auxiliary mechanism for promoting oil dripping is provided at the upper end of the limit strip and the lower ends of the two rotating bars.

[0007] Preferably, the adjustment drive mechanism includes a rotating rod rotatably connected inside a rectangular cavity. The outer side wall of the rotating rod is fixedly connected to a plurality of rectangular mesh plates at equal intervals along its circumference. The lower end of the rotating rod penetrates the inner bottom of the rectangular cavity and is fixedly connected to the upper end of the limiting strip.

[0008] Preferably, an electromagnet is embedded in the drive box, the electromagnet is located above the rectangular cavity, the drive box is made of magnetic shielding material, the rectangular cavity is filled with magnetorheological fluid, and a magnetic guide plate is embedded in the top of the rectangular cavity, the upper end of the magnetic guide plate is in contact with the lower end of the electromagnet.

[0009] Preferably, the lower end of the drive box is connected to multiple U-shaped plates, and the rotating rod passes through the U-shaped plates and is rotatably connected to the U-shaped plates through bearings.

[0010] Preferably, the auxiliary mechanism includes magnetic strips respectively embedded at the lower ends of the two rotating bars, and a plurality of guide rectangular rods are vertically arranged through the limiting bar. Each guide rectangular rod is slidably connected to the limiting bar, and a magnetic plate is fixedly connected to the upper end of each guide rectangular rod. The lower end of each magnetic plate is elastically connected to the upper end of the limiting bar through a spring.

[0011] Preferably, the magnetic plates are attracted to each other with opposite polarities on their adjacent surfaces, and each magnetic plate is fixedly connected to two connecting rods at its lower end, with an impact ball fixedly connected to the lower end of each of the two connecting rods.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. After the oil soaking is completed, the motor and electromagnet are started simultaneously. The rotation of the drive box will drive the rotating rod to rotate through the rectangular mesh plate. The rotation of the rotating rod will drive the steel template to rotate through the limit strip and the multiple hanging ear limit components on the limit strip. After the steel template rotates, it will be subjected to centrifugal force, and the excess oil on the steel template will be thrown off, realizing the rapid removal of oil. Compared with the existing technology, it can achieve a more efficient way of removing oil and reduce the time required to wait for the oil on the steel template to fall off.

[0014] 2. When the excess oil on the steel plate is almost completely shaken off, turn off the motor and electromagnet. Due to inertia, the steel template will continue to rotate. After the steel template rotates due to inertia, the limit strip, the two magnetic strips, and the rotating strip will move relative to each other, causing the limit strip to vibrate. As the steel template rotates due to inertia, the limit strip will vibrate continuously. The vibration force will be transmitted to the steel template through the hanging ear limit component, causing the steel template to vibrate continuously during the rotation due to inertia, shaking off the excess oil and simultaneously throwing it out through centrifugal force. The combination of these two actions can further improve the removal effect of excess oil. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Reference Figure 1-5 A bridge steel formwork anti-rust oil immersion auxiliary treatment device includes a connecting plate 1. A motor 2 is installed at the upper end of the connecting plate 1. The motor 2 is a self-locking motor. When the power is cut off, its output shaft will stop rotating immediately. The end of the output shaft of the motor 2 passes through the connecting plate 1 and is fixedly connected to a drive box 5. The connecting plate 1 is a circular plate when viewed from above. The upper end of the connecting plate 1 is connected to an external lifting and moving structure. In actual use, the entire device is moved up and down by the lifting and moving structure for oil immersion and subsequent movement. This is the prior art.

[0023] A limit strip 8 is provided below the drive box 5. Two hanging ear limit components 16 are symmetrically installed at the lower end of the limit strip 8. The hanging ear limit components 16 are existing technology and are used to connect with the hanging ears of the steel template.

[0024] As one embodiment of this utility model, in order to ensure that the rotation of the steel template is more stable, a connecting ring 4 is provided below the two limiting strips 8. A roller 10 is fixedly connected to the lower end of each limiting strip 8. The lower end of each roller 10 contacts the upper end of the connecting ring 4. The upper end of the connecting ring 4 is fixedly connected to the outer wall of the connecting plate 1 through multiple L-shaped mounting brackets 3.

[0025] In one embodiment of this utility model, the drive box 5 is provided with an adjustment drive mechanism for driving the limit bar 8 to rotate. The adjustment drive mechanism includes a rotating rod 9 rotatably connected in the rectangular cavity 17. The outer side wall of the rotating rod 9 is fixedly connected to multiple rectangular mesh plates 22 at equal intervals along its circumference. The lower end of the rotating rod 9 penetrates the inner bottom of the rectangular cavity 17 and is fixedly connected to the upper end of the limit bar 8. An electromagnet 20 is embedded in the drive box 5 and is located above the rectangular cavity 17. The drive box 5 is made of magnetic shielding material. By setting the magnetic shielding material, the magnetism of the electromagnet 20 can be prevented from affecting the rear. The magnetic strip 7 and magnetic plate 12 have an impact. The rectangular cavity 17 is filled with magnetorheological fluid 21. Magnetorheological fluid 21 is a new type of fluid with controllable flow. It is a relatively active research area in smart materials. When there is no external magnetic field, it exhibits the characteristics of a low-viscosity Newtonian fluid. When an external magnetic field is applied, it exhibits the characteristics of a high-viscosity, low-flow Bingham fluid. A magnetic plate 18 is embedded in the top of the rectangular cavity 17. The upper end of the magnetic plate 18 is in contact with the lower end of the electromagnet 20. The lower end of the drive box 5 is connected to multiple U-shaped plates 19. The rotating rod 9 passes through the U-shaped plate 19 and is rotatably connected to the U-shaped plate 19 through a bearing.

[0026] In one embodiment of this utility model, rotating bars 6 are fixedly connected to both sides of the drive box 5. The upper end of the limiting bar 8 and the lower ends of the two rotating bars 6 are jointly provided with an auxiliary mechanism for promoting oil dripping. The auxiliary mechanism includes magnetic bars 7 respectively embedded in the lower ends of the two rotating bars 6. Multiple guide rectangular rods 11 are vertically arranged through the limiting bar 8. Each guide rectangular rod 11 is slidably connected to the limiting bar 8. A magnetic plate 12 is fixedly connected to the upper end of each guide rectangular rod 11. The lower end of each magnetic plate 12 is elastically connected to the upper end of the limiting bar 8 through a spring 15. The multiple magnetic plates 12 are attracted to the adjacent surfaces of the corresponding magnetic bars 7 by opposite polarities. Two connecting rods 13 are fixedly connected to the lower end of each magnetic plate 12. An impact ball 14 is fixedly connected to the lower end of each of the two connecting rods 13.

[0027] In actual use, after the oil immersion is completed, the device is moved to a position where the steel template is removed from the oil surface. At the same time, the motor 2 and electromagnet 20 are started. The electromagnet 20 generates a large magnetic field. Under the influence of this magnetic field, the magnetorheological fluid 21 forms a low-flow Bingham fluid, which becomes almost solid. At this time, the rotation of the drive box 5 drives the rotating rod 9 to rotate through the rectangular mesh plate 22. The rotation of the rotating rod 9 drives the steel template to rotate through the limiting strip 8 and the multiple hanging ear limiting components 16 on the limiting strip 8. After the steel template rotates, it is subjected to centrifugal force, and the excess oil on the steel template is thrown off, realizing the rapid removal of oil. Compared with the existing technology, it can achieve a more efficient oil removal method and reduce the time required to wait for the oil on the steel template to fall off.

[0028] In actual use, when the excess oil on the steel plate is almost completely shaken off (a rough judgment can be made by observing the amount of oil shaken off per unit time), turn off the motor 2 and the electromagnet 20. Due to inertia, the steel template will continue to rotate, while the electromagnet 20 is de-energized and the magnetorheological fluid 21 returns to a low-viscosity fluid state. Therefore, the rotation of the rotating rod 9 will not be subject to much resistance at this time.

[0029] After the steel template rotates due to inertia, the limiting strip 8 will move relative to the two magnetic strips 7 and the rotating strip 6. At this time, multiple magnetic plates 12 will intermittently move closer to and away from the magnetic strips 7. When the magnetic plate 12 is close to the magnetic strip 7, it will be magnetically acted upon, and the magnetic plate 12 will move upward and stretch the corresponding spring 15. When the magnetic plate 12 is away from the magnetic strip 7, it will be elastically acted upon by the spring 15, and the magnetic plate 12 will move downward rapidly. It will then impact the limiting strip 8 through the connecting rod 13 and the impact ball 14, causing the limiting strip 8 to vibrate. In other words, after the steel template rotates due to inertia, the limiting strip 8 will vibrate continuously. The vibration force will be transmitted to the steel template through the hanging ear limiting component 16, causing the steel template to vibrate continuously during the rotation due to inertia, shaking off excess oil and simultaneously throwing it out through centrifugal force. The combination of the two can further improve the removal effect of excess oil.

[0030] During this process, due to friction hindering the rotation and the magnetic effect of magnetic strip 7 and magnetic plate 12, the rotation speed of the steel template will gradually slow down and eventually stop. At this point, the excess oil on the steel template has been basically removed, and the staff can carry out subsequent operations.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
