Technical Field
[0001] This utility model relates to the field of debris retrieval technology, and in particular to a debris retrieval device for the demolition of abandoned bridges. 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 rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Old and abandoned bridges, due to structural aging, reduced load-bearing capacity, or design flaws, may cause traffic accidents or pose a danger to pedestrians; therefore, it is necessary to demolish abandoned bridges in a timely manner.
[0003] During the demolition of abandoned bridges, some bridge debris inevitably falls into the river. This debris can accumulate and cause blockages, necessitating timely removal to ensure unobstructed water flow. Traditional bridge debris removal operations primarily rely on excavators. However, the excavator's retrieval points are often too scattered and haphazard, resulting in some debris remaining in the river and hindering its flow. Utility Model Content
[0004] The purpose of this application is to provide a device for salvaging debris from the demolition of abandoned bridges, in order to solve the problem mentioned in the background art that when using excavators to salvage bridge debris, the salvage points are too scattered and arbitrary, resulting in some bridge debris not being effectively salvaged and remaining in the river channel, affecting the smooth flow of the river.
[0005] To achieve the above objectives, this application provides the following technical solution: a debris retrieval device for dismantling abandoned bridges, comprising a first carrier plate, a first motor mounted on the bottom of the first carrier plate, a first gear connected to the output shaft of the first motor via a coupling, a first carrier column rotatably connected to the bottom of the first carrier plate via a bearing, a second gear fixedly sleeved on the outside of the first carrier column, the first gear and the second gear meshing with each other, a second carrier plate fixed to the bottom end of the first carrier column, a first hydraulic cylinder mounted on the second carrier plate, a fixed plate fixedly mounted on the output end of the first hydraulic cylinder, an inclination adjustment component mounted on the fixed plate, a bucket mounted on the inclination adjustment component, and the inclination adjustment component being used to adjust the orientation of the bucket opening, a shifting component mounted on the top of the first carrier plate, the shifting component being used to move the bucket in the river channel, a rotating mounting component mounted on the shifting component, and the rotating mounting component being mounted on a tractor vehicle to adjust the angle between the shifting component and the tractor vehicle.

Detailed Implementation
[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] Example: Reference Figure 1-6The device shown is for retrieving debris from the demolition of abandoned bridges. It includes a first carrier plate 1, a first motor 2 mounted on the bottom of the first carrier plate 1, and a first gear 3 connected to the output shaft of the first motor 2 via a coupling. A first carrier column 4 is rotatably connected to the bottom of the first carrier plate 1 via bearings. A second gear 5 is fixedly sleeved on the outside of the first carrier column 4, with the first gear 3 and the second gear 5 meshing with each other. A second carrier plate 6 is fixed to the bottom end of the first carrier column 4, and a first hydraulic cylinder 7 is mounted on the second carrier plate 6. A fixed plate 8 is fixedly mounted on the output end of the first hydraulic cylinder 7, and an inclination adjustment assembly is mounted on the fixed plate 8. A bucket 9 is mounted on the inclination adjustment assembly, and the inclination adjustment assembly is used to adjust the bucket. The opening orientation of the bucket 9 is adjusted by using the first motor 2 to drive the first gear 3 to rotate. The first gear 3 pulls the second gear 5 to rotate, which in turn drives the first carrier column 4 and the bucket 9 to rotate. This adjusts the opening orientation of the bucket 9 so that when the bucket 9 is moved to the middle of the river, it can be moved along the direction of the river with the help of a tractor to first scoop up the bridge debris in the middle of the river, which will facilitate the subsequent scooping of the bridge debris. A moving component is installed on the top of the first carrier plate 1. The moving component is used to move the bucket 9 in the river. A rotating mounting component is installed on the moving component. The rotating mounting component is installed on the tractor to adjust the angle between the moving component and the tractor. Using the transfer component, the bucket 9 is moved to the middle of the river channel. With the help of the first hydraulic cylinder 7, the bucket 9 is pushed down into the river channel. The inclination adjustment component can adjust the inclination angle of the bucket 9 so that the bucket 9 can be adapted to the slope of the river channel. In this way, under the traction of the transfer component, the bucket 9 can move from the middle of the river channel to the river bank in an orderly manner, and salvage the bridge debris in the river channel to the bank, ensuring that no salvage point is missed.
[0019] The tilt adjustment assembly includes a transmission box 10, which is fixedly mounted on a fixed plate 8. A transmission rod 11 is inserted into the transmission box 10. One end of the transmission rod 11 is rotatably connected to the inner wall of the transmission box 10 through a bearing, and the other end of the transmission rod 11 is fixedly mounted on the bucket 9. A seal is installed at the junction of the transmission box 10 and the transmission rod 11. A second hydraulic cylinder 13 is installed on the top of the transmission box 10. A third gear 12 is fixedly sleeved on the outside of the transmission rod 11. A vertical rod 14 is fixedly mounted on the output end of the second hydraulic cylinder 13. A slider 15 is fixedly mounted on the bottom end of the vertical rod 14. The slider 15 slides against the inner wall of the transmission box 10, and a rack 16 is fixedly mounted on the bottom of the slider 15. The rack 16 meshes with the third gear 12. The second hydraulic cylinder 13 is used to pull the vertical rod 14, the slider 15 and the rack 16 to move longitudinally. With the rack 16 meshing with the third gear 12, the rack 16 moves while the third gear 12 rotates. The third gear 12 pulls the transmission rod 11 to rotate, which in turn drives the bucket 9 to rotate. This makes it easy to adjust the tilt angle of the bucket 9 so that it can adapt to the river slope to facilitate the retrieval of bridge debris and to facilitate the unloading of the bridge debris retrieved from the bucket 9.
[0020] The moving component includes a rectangular frame plate 17. A lead screw 18 is rotatably connected between the left and right inner walls of the rectangular frame plate 17 via bearings. A second motor 19 is installed on the right side of the rectangular frame plate 17. The lead screw 18 is driven by the second motor 19. A lead screw nut is installed on the lead screw 18. A third carrier plate 20 is fixedly installed on the outside of the lead screw nut. A first carrier plate 1 is fixedly installed at the bottom of the third carrier plate 20. Two reinforcing guide rods 21 are fixed between the left and right inner walls of the rectangular frame plate 17. The third carrier plate 20 is slidably sleeved on the outside of the two reinforcing guide rods 21. The second motor 19 drives the lead screw 18 to rotate, and the lead screw 18 pulls the third carrier plate 20 to move, so that the third carrier plate 20 pulls the bucket 9 to move accordingly, moving between the middle of the river and the bank. In this way, it is convenient to complete the salvage work of bridge debris in the river. The two reinforcing guide rods 21 are used to share the force of the lead screw 18 and prevent the lead screw 18 from bending and deforming.
[0021] The rotary mounting assembly includes a carrier plate 22, a second carrier column 23 rotatably connected to the top of the carrier plate 22 via a bearing, a support seat 24 fixed to the top of the second carrier column 23, the support seat 24 fixedly installed at the bottom of the rectangular frame plate 17, a fourth gear 25 fixedly sleeved on the outside of the second carrier column 23, a third motor 26 mounted on the top of the carrier plate 22, a fifth gear 27 fixedly mounted at the output end of the third motor 26, and the fourth gear 25 and the fifth gear 27 meshing with each other. The carrier plate 22 is installed on the tractor, and the third motor 26 drives the fifth gear 27 to rotate. The fifth gear 27 drives the fourth gear 25 to rotate, so that the fourth gear 25 pulls the second carrier column 23 and the support seat 24 to rotate, thereby driving the moving component to rotate, so that the device can move together with the tractor.
[0022] The hydraulic cylinder is equipped with a power source, and the power source is configured as a standard feature in the field, which technicians can implement based on existing technology.
[0023] Working principle of this utility model: The carrier plate 22 is installed on the tractor, and the tractor is used to move the device. During the transfer, the rectangular frame plate 17 is kept parallel to the body of the tractor, and the bucket 9 is located at the rear of the vehicle, which makes it convenient for the device to move with the tractor. After the device is brought to the designated location in the river using a tractor, the third motor 26 is operated to drive the fifth gear 27 to rotate. The fifth gear 27 drives the fourth gear 25 to rotate, causing the fourth gear 25 to rotate the second support column 23 and the rectangular frame plate 17 by 90°. At this time, the rectangular frame plate 17 is positioned horizontally above the river. The second motor 19 is then operated to drive the lead screw 18 to rotate, causing the lead screw 18 to move the bucket 9 to the middle position in the river. The first motor 2 is then operated to drive the first gear 3 to rotate, causing the first gear 3 to rotate, which in turn drives the second gear 5 to rotate, causing the second gear 5 to rotate the first support column 4, thereby rotating the bucket 9 by 90°. Subsequently, the device is operated... The first hydraulic cylinder 7 pushes the bucket 9 downward, so that the bucket 9 contacts the bottom of the river. The tractor then drives the bucket 9 forward along the river, so that the bucket 9 scoops up the bridge debris in the middle of the river. The second hydraulic cylinder 13 pushes the rack 16 downward, and the rack 16 drives the third gear 12 to rotate. The third gear 12 pulls the bucket 9 to rotate via the transmission rod 11. In this way, the opening of the bucket 9 faces upward. The first hydraulic cylinder 7 is activated to drive the bucket 9 upward. The transfer component drives the bucket 9 to move towards the bank. Once the bucket 9 has moved to the bank, the second hydraulic cylinder 13 is retracted, causing the bucket 9 to flip over and dump the scooped bridge debris. Subsequently, the transfer component is used to drive the bucket 9 back to the middle of the river channel. The first motor 2 is then controlled to drive the bucket 9 back to its initial angle. Then, the first hydraulic cylinder 7 is used to push the bucket 9 down so that the bucket 9 contacts the bottom of the river channel. The tilt angle of the bucket 9 can be adjusted using the tilt adjustment component so that the bucket 9 can match the slope of the river channel. While the transfer component is used to move the bucket 9 towards the riverbank, the first hydraulic cylinder 7 is controlled to retract in an orderly manner so that the bucket 9 can move from the middle of the river channel to the riverbank. The bucket 9 will scoop up the bridge debris along the way and bring it to the riverbank. The device can be transferred to the other side of the riverbank using a tractor to complete the salvage operation of all the bridge debris in the river channel. The bridge debris salvaged to the riverbank can finally be transferred to the construction waste treatment plant for further processing using a loader and a dump truck.

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.
