Technical Field

[0001] This utility model belongs to the field of bridge maintenance technology, and in particular relates to a rust removal device for steel structure bridges. Background Technology

[0002] During long-term use, steel structure bridges are prone to rust due to environmental factors. If rust removal is not carried out in time, it will affect the structural safety and service life of the bridge.

[0003] Existing steel bridge rust removal equipment lacks the ability to collect dust during use, generating a large amount of dust during the rust removal process. This dust not only pollutes the surrounding environment but can also be inhaled by operators, endangering their health and reducing the effectiveness of the steel bridge rust removal equipment.

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

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-4 A rust removal device for steel structure bridges includes a base 1, a support block 2 fixedly connected to the upper surface of the base 1, an electric telescopic rod 12 fixedly connected to the inner bottom wall of the support block 2, and the telescopic end of the electric telescopic rod 12 fixedly connected to the bottom surface of an auxiliary block 3. The power generated by the electric telescopic rod 12 drives the support block 2 to move, thereby completing the height adjustment of the support block 2 to adapt to steel structure bridges of different heights and increase the applicability of the device.

[0019] The support block 2 has an auxiliary block 3 that is slidably connected inside. The auxiliary block 3 has a rust removal roller 13 that is rotatably connected inside. The left end of the rust removal roller 13 is fixedly connected to a servo motor 14. The servo motor 14 drives the rust removal roller 13 to rotate. When the rust removal roller 13 rotates, it will continuously rub against the surface of the steel structure bridge, thereby removing rust from its surface.

[0020] Two sets of electric wheels 4 are fixedly connected to the bottom surface of the base 1. An auxiliary bearing 15 is sleeved on the outer surface of the rust removal roller 13. The auxiliary bearing 15 is embedded in the inside of the auxiliary block 3. The auxiliary bearing 15 can reduce the friction generated by the rust removal roller 13 when rotating, making the rust removal roller 13 more sensitive when rotating. At the same time, it can also reduce the wear rate of the rust removal roller 13 and increase the durability of the rust removal roller 13.

[0021] The front of the support block 2 is fixedly connected to the intelligent controller 5. The inner wall of the auxiliary block 3 is fixedly connected to two suction square tubes 6. The upper surface of the base 1 is fixedly connected to the auxiliary box 7. The upper surface of the intelligent controller 5 is fixedly connected to the reinforcing block 20. The back of the reinforcing block 20 is fixedly connected to the front of the support block 2. The reinforcing block 20 can increase the fixed connection area between the intelligent controller 5 and the support block 2, thereby making the connection between the two more solid and preventing the possibility of breakage at the connection after long-term use, thus increasing the robustness of the device.

[0022] The upper surface of the auxiliary box 7 is fixedly connected to two delivery hoses 8. The left end of each delivery hose 8 passes through the support block 2 and is fixedly connected to the right end of the suction square tube 6. The left side of the auxiliary box 7 is fixedly connected to a negative pressure pump 9. The outer surface of the negative pressure pump 9 is fixedly connected to a fixing block 16. The right side of the fixing block 16 is fixedly connected to the left side of the auxiliary box 7. The fixing block 16 can increase the fixed connection area between the negative pressure pump 9 and the auxiliary box 7, thereby making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the robustness of the device.

[0023] The auxiliary box 7 is slidably connected to the collection box 10. The front of the collection box 10 is fixedly connected to the sliding block 17. The sliding block 17 is slidably connected to the inside of the auxiliary box 7. The sliding block 17 can move simultaneously with the collection box 10 and use the friction force generated by itself on the auxiliary box 7 during the movement to improve the stability of the collection box 10 when it moves, thereby increasing the stability of the device.

[0024] A filter plate 11 is fixedly connected to the inner wall of the collection box 10. The intelligent controller 5 is electrically connected to the electric wheel 4 and the negative pressure pump 9 through wires. An auxiliary handle 18 is fixedly connected to the right side of the collection box 10. An anti-slip rubber sleeve 19 is fixedly connected to the outer surface of the auxiliary handle 18. The cooperation between the auxiliary handle 18 and the anti-slip rubber sleeve 19 can provide a good force point for the collection box 10, increasing the convenience when pulling the collection box 10. The anti-slip rubber sleeve 19 can increase the firmness when gripping the auxiliary handle 18.

[0025] The working principle of this utility model is as follows: In use, first connect the electric wheel 4, intelligent controller 5, negative pressure pump 9, electric telescopic rod 12, and servo motor 14 to the power supply. Then, start the electric wheel 4 through the intelligent controller 5, causing it to move the base 1 to a suitable position. Next, use the electric telescopic rod 12 to move the support block 2 up and down within the auxiliary block 3, positioning the bridge within the groove of the support block 2. Simultaneously, bring the bridge surface into contact with the rust-removing roller 13. When rust removal is required, start the servo motor 14. The power generated by the servo motor 14 drives the rust-removing roller 13 to rotate. The auxiliary bearing 15 increases the sensitivity of the rust-removing roller 13 during rotation. The rust-removing roller 13 continuously rubs the surface of the steel bridge, thus completing the rust removal process. A large amount of dust is generated during the process. When dust collection is required, the negative pressure pump 9 is started to extract air from the auxiliary box 7, thereby creating a negative pressure. The negative pressure environment is then transmitted to the suction square pipe 6 through the delivery hose 8. The suction square pipe 6 continuously extracts air near the rust removal roller 13, and simultaneously draws the dust floating in the air into the auxiliary box 7. The filter plate 11 then filters the dust mixed in with the air, leaving the dust in the collection box 10. Excess air is discharged through the negative pressure pump 9. When further dust treatment is required, the auxiliary handle 18 is pulled, which causes the collection box 10 to slide out of the auxiliary box 7. This achieves the dust collection capability and effectively increases the applicability of the rust removal device for steel structure bridges.
