Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a rust removal device for steel bars used in bridge construction. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the modern, rapidly developing transportation industry, the term "bridge" has also been extended to refer to a structure erected to cross mountains, ravines, adverse geological conditions, or to meet other transportation needs, making travel more convenient. A bridge generally consists of a superstructure, substructure, supports, and ancillary structures. The main structure of a bridge is generally reinforced steel, which refers to steel used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners, including plain round steel bars, ribbed steel bars, and twisted steel bars, which are used extensively in bridge construction and engineering projects.

[0003] For example, Chinese utility model patent application number 202221268055.7 discloses a rust removal device for steel bars used in bridge construction, including a workbench. A drive mechanism is fixedly connected to one end of the workbench and extends into the workbench. A transmission mechanism is slidably connected inside the workbench and cooperates with the drive mechanism. A grinding device is rotatably connected to the transmission mechanism. A fixing mechanism is rotatably connected to one end of the inner surface of the workbench and meshes with the drive mechanism. This device can automatically grind steel bars in all directions, improving work efficiency and rust removal quality.

[0004] The aforementioned patent uses a fixed chuck to fix one end of the reinforcing bar, and the rotation of the fixed chuck causes the reinforcing bar to rotate. Then, a moving grinding block is used to grind the reinforcing bar. Therefore, it can only remove rust from reinforcing bars shorter than the length of the equipment, and cannot remove rust from reinforcing bars longer than the equipment. Furthermore, the grinding parts in this patent cannot be easily replaced, and since the grinding parts are consumable parts, they need to be replaced after a period of use to ensure the efficiency of grinding and rust removal.

[0027] The steel bars are conveyed by two sets of roller conveyor components, and the rotating grinding blocks 6 are used to grind the steel bars thoroughly. It can grind and remove rust from steel bars that exceed the length of the equipment, and is convenient for removing rust from whole steel bars with common lengths of 6 meters, 9 meters, 12 meters or longer, thus improving the applicability of the steel bar rust removal device.

[0028] The roller conveyor assembly includes a threaded rod 8 and a fixed mounting frame 9. The threaded rod 8 is rotatably mounted on the processing table 1. A threaded block 10 is threadedly connected to the outer surface of the threaded rod 8, and a handwheel 11 is fixedly connected to one end of the threaded rod 8. The threaded block 10 is slidably mounted on the processing table 1, and a movable mounting frame 12 is fixedly connected to the top of the threaded block 10. Two curved conveyor rollers 13 are arranged between the movable mounting frame 12 and the fixed mounting frame 9 on opposite sides. Rectangular mounting blocks 14 are fixedly connected to both ends of the curved conveyor rollers 13. Rectangular mounting frames 15 are movably fitted onto the outer surfaces of the two rectangular mounting blocks 14. The two rectangular mounting frames 15 are rotatably connected to the fixed mounting frame 9 and the movable mounting frame 12, respectively. A drive motor 16 is fixedly mounted on the side of the fixed mounting frame 9 away from the movable mounting frame 12. The output end of the drive motor 16 is fixedly connected to one of the rectangular mounting frames 15 on the fixed mounting frame 9. The curved conveyor rollers 13 are made of rubber material and are thicker at both ends and thinner in the middle.

[0029] The rotating assembly includes a rotary motor 17 fixedly installed at the bottom of the processing table 1. A drive gear 18 is fixedly connected to the output end of the rotary motor 17. A drive gear ring 19 meshes with the outer surface of the drive gear 18. The drive gear ring 19 is fixedly sleeved on the outer surface of the rotary disk 3.

[0030] The sliding assembly includes an annular slide rail 20 fixedly installed on the inner wall of the mounting groove 2. Several sliders 21 are slidably connected inside the annular slide rail 20. The side of the sliders 21 away from the annular slide rail 20 is fixedly connected to the rotating disk 3.

[0031] The clamping assembly includes a pin 22 that moves through the rotating disk 3 and extends into the clamping hole 7. A pull block 23 is fixedly connected to one end of the pin 22 away from the clamping hole 7. A spring 24 is fixedly connected between the pull block 23 and the opposite side of the rotating disk 3.

[0032] Working principle: In use, first start the drive motor 16. The output end of the drive motor 16 rotates, driving the rectangular mounting frame 15 fixedly connected to it to rotate, and driving the curved conveyor roller 13 to rotate through the rectangular mounting block 14. Then, the worker holds the steel bar to be derusted and inserts one end between two curved conveyor rollers 13 in one of the roller conveyor assemblies. The rotating curved conveyor roller 13 conveys the steel bar to the side closer to the grinding block 6. The worker uses auxiliary tools to make the steel bar pass through the annular slide rail 20 and the rotating disk 3 in sequence and be located between multiple grinding disks, with the steel bar abutting against the grinding disks. At this time, start the rotary motor 17. The output end of the rotary motor 17 rotates, driving the drive gear 18 to rotate. The rotating disc 3 rotates, causing the drive gear ring 19 to rotate, which in turn drives the rotating disk 3 to rotate, and causes multiple grinding blocks 6 to move around the steel bar in a circular motion, thus grinding and removing rust from the steel bar. When the ground steel bar moves to the vicinity of another set of roller conveyor components, the staff will use auxiliary work to move the steel bar between the two curved conveyor rollers 13. At this time, the steel bar can be conveyed by the two sets of roller conveyor components, and the rotating grinding blocks 6 will be used to grind the steel bar thoroughly. It can grind and remove rust from steel bars that exceed the length of the equipment, and is convenient for removing rust from whole steel bars with common lengths of 6 meters, 9 meters, 12 meters or longer, thus improving the applicability of the steel bar rust removal device.

[0033] When the grinding block 6 needs to be replaced after the device has been used for a period of time, the operator manually pulls the pull block 23 away from the rotating disk 3 while the machine is stopped. This causes the spring 24 to stretch and store energy. The movement of the pull block 23 causes the pin 22 to move until the pin 22 exits the locking hole 7, releasing the limiting fixation of the mounting rod 5. Then, the mounting rod 5 is pulled out of the rectangular mounting port 4 to remove the grinding block 6. Conversely, the mounting rod 5 is inserted into the rectangular mounting port 4, so that the locking hole 7 is aligned with the pin 22. Then, the pull block 23 is released, and the spring force of the spring 24 causes the pin 22 to be inserted into the locking hole 7, thus completing the installation of the grinding block 6.

[0034] When the curved conveyor roller 13 needs to be replaced, in the stopped state, the operator manually rotates the handwheel 11 clockwise to rotate the threaded rod 8. Under the limiting action of the processing table 1 on the threaded block 10, the threaded block 10 moves along the axial direction of the threaded rod 8, and drives the movable mounting frame 12 to move away from the fixed mounting frame 9. This causes the rectangular mounting frame 15 on the movable mounting frame 12 and the rectangular mounting frame 15 on the fixed mounting frame 9 to move to opposite sides, allowing the operator to disassemble the curved conveyor roller 13. Conversely, one rectangular mounting block 14 on the curved conveyor roller 13 is inserted into the rectangular mounting frame 15 on the fixed mounting frame 9, and the other rectangular mounting block 14 is opposite to the rectangular mounting frame 15 on the movable mounting frame 12. Then, the handwheel 11 is rotated counterclockwise to move the movable mounting frame 12 closer to the fixed mounting frame 9 until the rectangular mounting frame 15 on the movable mounting frame 12 is fitted onto the opposite rectangular mounting block 14, thus completing the replacement of the curved conveyor roller 13.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
