[0001] This utility model relates to the field of steel structure rust removal technology, specifically a steel structure rust removal device. Background Technology

[0002] In the fields of industrial production and construction, steel structures are widely used due to their high strength and good stability. However, steel structures are prone to rust when exposed to the external environment for a long time. If rust is not removed in time, it will affect the structural strength and service life of the steel structure. Therefore, rust removal of steel structures is an important process in related fields.

[0003] Existing steel structure rust removal equipment often encounters problems during rust removal operations. Due to variations in the degree of damage to the protective layer and stress distribution on the steel structure surface, rust depths can vary significantly. The equipment struggles to adjust the grinding position accordingly, leading to either incomplete or excessive grinding of rust, and failing to meet the grinding requirements of different rust levels. Furthermore, the equipment cannot simultaneously clean up rust residue generated during grinding, which tends to accumulate on the steel structure surface and even splatter onto already derusted areas, ultimately affecting the overall rust removal quality.

[0004] Therefore, we propose a steel structure rust removal device to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: This example aims to address the problems of existing rust removal devices, such as difficulty in precisely grinding rust of varying depths and the inability to flexibly adjust the grinding spacing during secondary grinding. Please refer to [link to example]. Figure 1 - Figure 4A steel structure rust removal device includes a workbench 1, a support frame 2 fixedly connected to the workbench 1, a grinding component 3 and a cleaning component 4 provided on the support frame 2, the grinding component 3 includes a motor 31 fixedly connected to the side wall of the support frame 2, a lead screw 32 fixedly connected to the output end of the motor 31, the lead screw 32 being rotatably connected to the support frame 2, a rotating shaft 33 being rotatably connected to the support frame 2, and a clamping component 5 installed on the workbench 1.

[0025] A guide rod 34 is fixedly connected to the side end of the rotating shaft 33. The guide rod 34 is rotatably connected to the support frame 2. A retaining strip 35 is fixedly connected to the outer ring of the guide rod 34. A sliding seat 36 is threaded onto the lead screw 32. A sleeve rod 37 is rotatably connected to the sliding seat 36. The inner wall of the sleeve rod 37 has symmetrically opened retaining grooves 371. The sleeve rod 37 has a through-type structure in the middle. The retaining grooves 371 are adapted to the retaining strip 35. A helical gear 38 is fixedly sleeved on the outer ring of the sleeve rod 37. A... Support shaft 39 is hollow and has a helical gear 310 rotatably connected to its top. Helical gear 310 meshes with helical gear 38. Helical gear 310 is threaded with a threaded rod 311. Both sliding seat 36 and support shaft 39 are hollow structures. The threaded rod 311 does not slide in contact with the inner walls of either of them, but only passes through their inner cavities. The threaded rod 311 and helical gear 310 form a threaded engagement, and the lifting is achieved by driving helical gear 310.

[0026] A fixed rod 312 is fixedly connected to the bottom end of the threaded rod 311, and a telescopic rod 313 is fixedly connected to the top surface of the fixed rod 312. The end of the telescopic rod 313 away from the fixed rod 312 is fixedly connected to the sliding seat 36. An electric grinder 314 is installed at the bottom end of the fixed rod 312.

[0027] In this embodiment: First, the steel structure is stably placed on the workbench 1 using auxiliary equipment, and the area of ​​the steel structure to be ground and rusted is adjusted to the working position of the electric grinder 314. Then, the clamping assembly 5 on the workbench 1 is started. The clamping assembly 5 consists of a cylinder and a clamping plate. The cylinder drives the clamping plate to move smoothly towards the steel structure until the clamping plate is tightly fitted with the steel structure, thus achieving a firm fixation of the steel structure and effectively preventing displacement of the steel structure during the grinding process, ensuring the accuracy of rust removal and grinding.

[0028] After the fixing is completed, start motor 31. The output end of motor 31 drives the lead screw 32 fixedly connected to it to rotate. When the lead screw 32 rotates, it drives the sliding seat 36 threaded to it to move horizontally along the support frame 2. During the movement of the sliding seat 36, the upper sleeve 37 moves synchronously with the guide rod 34, thereby driving the electric grinder 314 to smoothly fit against the steel structure surface to carry out rust removal and grinding operations.

[0029] Because rust on the steel structure surface varies in depth, an external rust detection sensor can be installed on the electric grinder 314 as needed. This sensor monitors the ground areas of the steel structure in real time during grinding, determining whether the rust has been thoroughly removed and promptly relaying the results to the workers. When workers receive feedback from the sensor indicating that some areas of the steel structure have not been properly ground and require secondary grinding, they can manually rotate the handle at the end of the rotating shaft 33. The handle drives the guide rod 34, which is fixedly connected to it, to rotate synchronously. The retaining strip 35 on the outer ring of the guide rod 34 engages with the retaining groove 371 inside the sleeve rod 37, driving the sleeve rod 37 to rotate synchronously, which in turn drives the helical gear 38 on its outer ring to rotate.

[0030] Helical gear 1 38 meshes with helical gear 2 310, causing helical gear 2 310 to rotate synchronously at the top of the support shaft 39. When helical gear 2 310 rotates, it drives the threaded rod 311, which is threaded to it, to move vertically up and down along the support shaft 39 and the sliding seat 36. The threaded rod 311 drives the fixed rod 312 at its bottom to move up and down synchronously, thereby adjusting the distance between the electric grinder 314 and the steel structure surface, ensuring that the electric grinder 314 is aligned with the area requiring secondary grinding. The telescopic rod 313 between the fixed rod 312 and the sliding seat 36 extends and retracts synchronously with the raising and lowering of the fixed rod 312, providing stable support and guidance for the fixed rod 312, ensuring that the raising and lowering process of the electric grinder 314 is smooth and without deviation.

[0031] During the second grinding process, the built-in sensor of the electric grinder 314 continuously monitors the grinding effect until the test results show that the grinding of the rust on the steel structure meets the preset rust removal requirements. The staff first turns off the electric grinder 314, controls the cylinder of the clamping component 5 to reset, separates the clamping plate from the steel structure, releases the fixed constraint on the steel structure, and finally removes the steel structure after grinding and rust removal from the workbench 1 using auxiliary equipment, thus successfully completing the entire rust removal and grinding process of the steel structure.

[0032] Example 2: This example aims to solve the problem of easy accumulation of grinding debris, which cannot be cleaned simultaneously and affects the quality of rust removal. This example is an improvement on Example 1. For details, please refer to Example 1. Figure 4 - Figure 7 The cleaning component 4 includes a suction fan 41 mounted on a sliding seat 36. The suction fan 41 is connected to a chip discharge pipe 42 and a chip suction pipe 44. The end of the chip discharge pipe 42 away from the suction fan 41 is connected to a chip collection cylinder 43. The chip collection cylinder 43 is fixedly connected to the sliding seat 36. The chip suction pipe 44 is connected to two branch pipes 45. Each of the two branch pipes 45 away from the chip suction pipe 44 is equipped with a suction hood 46. A support rod 47 is sleeved on the outside of the branch pipe 45. The support rod 47 is fixedly connected to the sliding seat 36.

[0033] A second motor 48 is fixedly connected to the sliding seat 36. A rotating shaft 49 is fixedly connected to the output end of the second motor 48. A disc 410 is fixedly connected to the rotating shaft 49. A through hole 411 is opened on the disc 410. A U-shaped frame 412 is fixedly connected to the sliding seat 36. The rotating shaft 49 is rotatably connected to the U-shaped frame 412. A support column 431 is fixedly connected to the U-shaped frame 412. A rotating frame 413 is rotatably sleeved on the outer ring of the support column 431. A T-shaped rod 414 is slidably connected to the rotating frame 413. A connecting plate 415 is fixedly connected to the rotating frame 413. The T-shaped rod 414 is slidably connected to the through hole 411. A brush 416 is fixedly connected to the bottom end of the connecting plate 415.

[0034] In this embodiment: When the electric grinder 314 grinds and removes rust from the steel structure, it will generate a large amount of rust residue and fumes. These debris are easy to fall and accumulate on the surface of the steel structure, interfering with the sensor's judgment of the degree of rust grinding, and thus affecting the overall rust removal quality. Therefore, it is necessary to clean the surface of the steel structure and the surrounding area at the same time during the grinding process.

[0035] While the electric grinder 314 starts operation, the second motor 48 and the suction fan 41 are started simultaneously. The second motor 48 drives the rotating shaft 49, which is fixedly connected to it, to rotate. The rotating shaft 49 drives the disc 410 at its end to rotate synchronously. The through hole 411 on the disc 410 forms a sliding fit with the T-shaped rod 414 on the rotating frame 413. The end of the T-shaped rod 414 is provided with an anti-detachment limiting block, the outer diameter of which is larger than the diameter of the through hole 411. When the disc 410 rotates, the inner wall of the through hole 411 forms a sliding fit with the rod body of the T-shaped rod 414. At the same time, the anti-detachment limiting block prevents the T-shaped rod 414 from disengaging from the disc 410, ensuring that the rotational power of the disc 410 is continuously transmitted to the T-shaped rod 414, thereby driving the rotating frame 413 to reciprocate around the support column 431. When the rotating frame 413 swings, the connecting plate 415 drives the brush 416 at the bottom to reciprocate synchronously. The brush 416 closely adheres to the surface of the steel structure and sweeps the residual debris after grinding evenly to both sides, effectively preventing the debris from accumulating in the grinding area and affecting subsequent grinding and inspection operations.

[0036] Both sides of the brush 416 are equipped with suction hoods 46. The suction hoods 46 are connected to the suction fan 41 through branch pipes 45 and chip suction pipes 44. The support rods 47 sleeved on the outside of the branch pipes 45 can provide stable support for the branch pipes 45. After the debris is swept to both sides by the brush 416, the debris is confined within the effective adsorption range of the suction hoods 46 on both sides. The negative pressure generated by the start of the suction fan 41 draws these debris into the branch pipes 45 through the suction hoods 46, and then into the suction fan 41 through the chip suction pipes 44. Subsequently, the suction fan 41 discharges the debris into the debris collection cylinder 43 through the chip discharge pipe 42, realizing the centralized and unified collection and treatment of grinding debris.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
