[0002] The waste residue recovery device for bridge construction can be hung on a bridge guardrail. During operation, it can accurately receive the concrete and metal waste residue generated by the breaking of the guardrail, preventing the waste residue from falling and causing injury, and improving the safety of construction. It is suitable for scenarios such as bridge maintenance and reconstruction.

[0003] During the breaking operation of the bridge guardrail, independent breaking equipment such as impact hammers and cutting machines is often used in combination with temporarily erected boards or protective nets. Since the breaking point of the guardrail is close to the edge of the bridge deck, the concrete and metal waste residue generated by breaking is easily impacted and splashed, or leaks through the gaps in the enclosure. At the same time, the vibration of some breaking equipment during operation can also increase the falling of waste residue, ultimately causing the waste residue to fall directly onto the bridge below.

[0004] However, the existing equipment lacks targeted waste residue interception and collection structures, which cannot prevent the waste residue from falling, and may cause safety accidents such as injury and scratches to personnel under the bridge. In severe cases, it can even endanger life. In addition, falling waste residue can also damage infrastructure such as roads and pipelines under the bridge, increasing maintenance costs. At the same time, the scattered waste residue needs to be cleaned up later, prolonging the construction period. If the waste residue falls into water, it may also cause environmental pollution, further expanding the scope of influence. SUMMARY

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 In the embodiments of the present application, a waste recovery device for bridge construction includes a fixed frame 1, a collecting plate 2 is fixedly installed in the inner cavity of the fixed frame 1 through bolts, the inside of the collecting plate 2 is provided with a collecting groove for collecting waste generated by bridge demolition, and a mounting frame 3 is welded on the top surface of one end of the fixed frame 1.

[0027] The top end of the mounting frame 3 is fixedly provided with a positioning assembly 6 for assisting in positioning the collecting plate 2, and the inner cavity of the collecting plate 2 is rotatably provided with a crushing assembly 7 for refining the large waste residues and reducing the space occupied in the collecting groove, facilitating the subsequent transportation and treatment of the waste residues.

[0028] It should be noted that the fixed frame 1 is a core support frame of the device, and the collecting plate 2 is stably installed by bolts, so as to ensure that the collecting plate 2 does not deviate during operation. In use, the positioning assembly 6 is sleeved on the outer wall of the bridge guardrail, so that the fixed frame 1 and the collecting plate 2 are installed on one side of the bridge guardrail, thereby providing accurate position guarantee for waste residue collection. In addition, the side of the collecting plate 2 away from the guardrail is higher, which can expand the protection range and form a longitudinal protection barrier, thereby greatly reducing the splashing of waste residues caused by crushing impact. At the same time, after the bridge guardrail is crushed, the embedded steel bars in the bridge guardrail are exposed. The end of the cable 5 away from the mooring hook 4 is tied to the steel bars, thereby further enhancing the fixing effect, preventing the collecting plate 2 from moving during operation, preventing gaps between the collecting plate 2 and the bridge guardrail, ensuring that the waste residues can be effectively intercepted and collected, and reducing the risk of falling waste residues.

[0029] It should be further noted that the fixed box 701 is a support carrier of the crushing assembly 7, and is used for fixing and supporting the two crushing rollers 702. During work, the two crushing rollers 702 extrude and shear the large waste residues in the collecting plate 2, thereby refining the large waste residues into small particles, reducing the space occupation of the waste residues in the collecting groove, facilitating subsequent transportation, and avoiding blockage or accidental falling of the large waste residues.

[0030] Please refer to Figure 2 , Figure 4 The positioning assembly 6 includes a connecting frame 601 fixedly connected to the top end of the mounting frame 3, and the inner cavity of the connecting frame 601 is rotatably provided with two groups of driving rods 602. The ends of the two groups of driving rods 602 away from each other are rotatably connected to a transmission plate 603 through a pin shaft. The inner cavity bottom end of the transmission plate 603 is fixedly provided with a clamping plate 604 through a bolt, which is used for clamping the bridge guardrail. The clamping plate 604 is in close contact with the bridge guardrail, thereby achieving preliminary fixation of the position of the collecting plate 2.

[0031] The inner end of each of the two groups of driving rods 602 is fixedly provided with a driving gear 605. The lower side of the driving rod 602 is provided with an auxiliary rod 606, and the two ends of the auxiliary rod 606 are rotatably connected to the connecting frame 601 and the transmission plate 603 through a pin shaft, respectively. The auxiliary rod 606 plays a role in auxiliary support and transmission, thereby ensuring the stability of the movement of the transmission plate 603.

[0032] It should be noted that the two sets of drive gears 605 mesh with each other and are rotatably connected to the connecting frame 601 through pins. A drive motor 607 is fixedly installed on one side of the connecting frame 601. The output end of the drive motor 607 is fixedly connected to the pin in the inner cavity of one set of drive gears 605. When the drive motor 607 is working, it drives the drive gear 605 connected to it to rotate, and drives the other set of drive gears 605 and the drive rod 602 to rotate through gear transmission, thereby realizing the movement of the transmission plate 603 and the clamping plate 604 and completing the clamping or releasing action of the bridge railing.

[0033] It should also be noted that a cover plate 608 is fastened to the side of the connecting frame 601 away from the drive motor 607, and the two are locked together by bolts. After removing the cover plate 608, it is convenient to repair or replace internal parts such as the drive gear 605. A connector 609 is fixedly connected to the top surface of the connecting frame 601 by bolts, and the connector 609 is fixedly connected to the mounting frame 3 by bolts, so as to achieve a stable connection between the positioning component 6 and the mounting frame 3.

[0034] Please see Figure 2 , Figure 5 The crushing component 7 also includes a transmission gear 703. There are two sets of transmission gears 703, both located inside the fixed box 701. The two transmission gears 703 mesh with each other and are fixedly connected to the two crushing rollers 702 respectively. A power motor 705 is fixedly installed on the inner wall of the fixed box 701, and the output shaft of the power motor 705 is fixedly connected to one of the transmission gears 703. The power motor 705 has a torque adjustment gearbox. More specifically, the output end of the power motor 705 is connected to the input end of the torque adjustment gearbox, and the output shaft of the torque adjustment gearbox is connected to one of the transmission gears 703.

[0035] It should be noted that when the power motor 705 is working, it can drive the two crushing rollers 702 to rotate synchronously through the meshing of the transmission gear 703, thus providing power for the crushing of waste residue.

[0036] It should also be noted that there is a certain gap between the crushing roller 702 and the bottom of the inner cavity of the collecting plate 2. This gap allows the crushed waste residue to fall smoothly into the bottom of the collecting tank, which is convenient for subsequent centralized collection. At the same time, the arrangement of the two crushing rollers 702 can cover the crushed waste residue to a certain extent, reducing the problem of waste residue being blown up by the wind.

[0037] A connecting plate 704 is fixedly installed on the outer wall of the fixing box 701, and the connecting plate 704 is fixedly connected to the fixing frame 1 by bolts;

[0038] Need to explain, by setting the connecting plate 704 and bolt, can be in the crushing operation, the crushing assembly 7 is firmly fixed to the fixed frame 1, avoid the influence of the crushing effect, guarantee the structure stability, need to discharge the collection groove waste, can remove the bolt and take down the crushing assembly 7, provide sufficient space for cleaning, avoid the obstruction caused by the waste discharge, improve the cleaning efficiency, and in the subsequent maintenance or replacement of the crushing assembly 7, also can be quickly taken out by disassembling the connecting plate 704, reduce the operation difficulty.

[0039] Please refer to Figure 3 The fixed frame 1 is fixedly connected with the cable hook 4 at the top surface away from the mounting frame 3, and the cable hook 4 is rotatably sleeved with the cable 5, which is used for further strengthening the connection and reinforcing effect.

[0040] The working principle of the utility model is:

[0041] When the device of the utility model is used, first, before operation, the driving motor 607 drives the driving gear 605 to rotate, the driving rod 602 and the auxiliary rod 606 push the transmission plate 603, the clamping plate 604 clamps the bridge guardrail, then one end of the cable 5 is tied on the exposed reinforcing bar of the guardrail, to ensure that the fixed frame 1 and the collection plate 2 are stably attached to one side of the guardrail, and the high side of the collection plate 2 forms a protective barrier.

[0042] When the guardrail is broken, the waste falls into the collection groove of the collection plate 2, the power motor 705 of the crushing assembly 7 drives the two crushing rollers 702 to rotate through the transmission gear 703, the large waste is extruded and sheared to be refined, the refined waste falls into the groove bottom through the gap between the crushing roller 702 and the collection plate 2, the space occupation is reduced, and the two crushing rollers 702 are arranged to form a certain obstruction, the waste is lifted due to the action of wind force, dust pollution or fine waste particles are avoided.

[0043] After operation, the driving motor 607 drives the driving gear 605 to rotate reversely again, so that the clamping plate 604 loosens the bridge guardrail, the fixed frame 1 and the collection plate 2 are taken down as a whole, then the connecting plate 704 is disassembled to take down the crushing assembly 7, the waste in the collection groove can be quickly cleaned, and the recycling process is completed.
