Description

Technical Field

[0001] This utility model relates to the field of special operation equipment, and in particular to a track adjustment structure and a drainage tracked robot. Background Technology

[0002] With the acceleration of urbanization, the load on underground spaces, low-lying road sections, and drainage systems is constantly increasing, and rainstorms or sudden flooding events occur frequently. Traditional manual drainage methods have significant limitations in terms of efficiency, safety, and continuous operation capability. Existing drainage equipment mainly relies on fixed or vehicle-mounted pumping systems, which have poor mobility and cannot penetrate into complex flooded environments.

[0003] While commonly used tracked drainage equipment possesses a certain degree of terrain adaptability, its track tensioning structure is generally quite simple, often employing fixed tensioning wheels or ordinary elastic tensioning structures. During prolonged operation or travel on complex terrain, the tracks are prone to loosening, slippage, or even derailment, severely impacting the equipment's stability and operational efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a track adjustment structure and a drainage tracked robot, which solves the problems of insufficient track tensioning structure, difficulty in adjusting tension according to working conditions, and the risk of slippage and derailment.

[0005] To achieve this objective, the present invention adopts the following technical solution: A track adjustment structure includes: a track wheel and an adjustment assembly; The adjustment assembly includes an adjustment wheel and a telescopic part. The adjustment wheel is disposed inside the track wheel, and the telescopic part is fixedly connected to the adjustment wheel.

[0006] Preferably, a frame is mounted on the side of the track wheel, a vehicle body is fixedly connected to the top of the frame, and a winding assembly is provided inside the vehicle body.

[0007] Preferably, the vehicle body is equipped with a fuel tank, which is connected to a generator via a pipeline, and one end of the generator is fixedly connected to an exhaust pipe.

[0008] Preferably, the outer surface of the track wheel is provided with anti-slip protrusions.

[0009] Preferably, the telescopic part includes: a hydraulic cylinder, a push frame, and a hydraulic connector. The hydraulic cylinder is fixedly connected to the inside of the vehicle body. The telescopic end of the hydraulic cylinder is fixedly connected to the push frame. The hydraulic cylinder is connected to the hydraulic connector via a pipeline. One end of the push frame is fixedly connected to the adjusting wheel. The push frame is slidably connected to the inside of the vehicle body.

[0012] Preferably, the winding assembly includes a winding frame and a drive motor. The winding frame is rotatably mounted on the vehicle body, and the drive motor is mounted on the vehicle body and is used to drive the winding frame to rotate.

[0013] A tracked robot for flood drainage includes a track adjustment structure as described above.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By setting an adjusting wheel inside the track wheel and fixing the adjusting wheel to the telescopic part, the adjusting wheel can actively move along the inner side of the track under the drive of the telescopic part, thereby changing the force path of the track and realizing real-time and controllable adjustment of the track tension. This avoids problems such as slippage and derailment caused by looseness in traditional track structures, and improves the stability and passability of the equipment in complex road conditions.

[0019] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] refer to Figure 1 - Figure 3 As shown, this utility model embodiment provides a track adjustment structure and a drainage tracked robot, including: track wheels 1 and adjustment components 2; the adjustment components 2 are used to adjust the tension of the track.

[0023] The adjustment assembly 2 includes an adjustment wheel 210 and a telescopic part 220. The adjustment wheel 210 is located inside the track wheel 1, and the telescopic part 220 is fixedly connected to the adjustment wheel 210. The telescopic part 220 is used to drive the adjustment wheel 210 to rise and fall.

[0024] During drainage, the telescopic part 220 is remotely controlled from the outside. By activating the remote control, the telescopic part 220 retracts along the first direction, causing the telescopic part 220 to drive the adjusting wheel 210 to move along the first direction to the tension position within the track of the track wheel 1. The adjusting wheel 210 is adjusted to the inside of the track, pushing the track to extend upward to the maximum. The adjusting wheel 210 effectively increases the contact path of the track, and at this time the track is taut. At the same time, when the telescopic part 220 is extended along the second direction by remote control, the telescopic part 220 drives the adjusting wheel 210 to move to the slack position along the second direction in the track of the track wheel 1. The track will synchronously press down against the adjusting wheel 210 because it is not supported by the adjusting wheel 210. The adjusting wheel 210 is equivalent to shortening the contact path of the track, thereby making the track slack.

[0025] refer to Figure 2 and Figure 3 As shown, the telescopic part 220 includes: a hydraulic cylinder 221, a push frame 222, and a hydraulic connector 223. The hydraulic cylinder 221 is fixedly connected to the inside of the vehicle body 3. The telescopic end of the hydraulic cylinder 221 is fixedly connected to the push frame 222. The hydraulic cylinder 221 and the hydraulic connector 223 are connected by a pipeline. One end of the push frame 222 is fixedly connected to the adjusting wheel 210. The push frame 222 is slidably connected to the inside of the vehicle body 3.

[0026] When draining water, first connect the hydraulic connector 223 to the external liquid supply device through a pipeline, then start the remote control hydraulic cylinder 221, so that the extension end of the hydraulic cylinder 221 pushes the push frame 222, and then the push frame 222 pushes the adjusting wheel 210 to move along the first direction or the second direction. When the pusher 222 pushes the adjusting wheel 210 along the first direction on the inner side of the track of the track wheel 1, the pusher 222 continuously moves the adjusting wheel 210 along the first direction. The adjusting wheel 210 pushes the support point of the track upward. When the adjusting wheel 210 moves to the tightening position along the first direction, the adjusting wheel 210 pushes the track upward to the maximum extent on the inner side of the track, so that the adjusting wheel 210 effectively increases the contact path of the track. At this time, the track is taut. When the pusher 222 pushes the adjusting wheel 210 along the second direction on the inner side of the track of the track wheel 1, the pusher 222 continuously moves the adjusting wheel 210 along the second direction, so that the adjusting wheel 210 is adjusted to push the track back continuously on the inner side of the track. When the adjusting wheel 210 moves to the slack position along the second direction, the track will synchronously press down against the adjusting wheel 210 because it is no longer supported by the adjusting wheel 210. This makes the adjusting wheel 210 equivalent to shortening the contact path of the track, thereby making the track slack.

[0027] It should be noted that the tightening position refers to the position where the adjusting wheel 210 is located at the 3rd position on the vehicle body, while the slack position refers to the position where the adjusting wheel 210 is located at the 4th position on the frame.

[0028] refer to Figure 1 - Figure 3 As shown, a frame 4 is mounted on the side of the track wheel 1, and a vehicle body 3 is fixedly connected to the top of the frame 4. An oil tank 6 is installed inside the vehicle body 3, and a generator 7 is connected to the oil tank 6 through a pipe. An exhaust pipe 8 is fixedly connected to one end of the generator 7. Anti-slip protrusions 101 are provided on the outer surface of the track wheel 1. A fixing frame 9 is fixedly connected inside the vehicle body 3. A cooler 10 is fixedly connected to the top of the fixing frame 9. A fan 11 is fixedly connected to the bottom of the cooler 10. A water storage tank 12 is connected to the cooler 10. A drain pump 13 is fixedly connected to the bottom of the frame 4.

[0029] When the system is activated, the fuel tank 6 inside the vehicle body 3 supplies fuel to the generator 7 through the pipeline. The generator 7 starts to run and provides power to the whole vehicle, including the drive of the track wheels 1, the drainage pump 13, the cooler 10, etc. One end of the generator 7 discharges the exhaust gas generated during operation through the exhaust pipe 8. The robot starts to move under the drive of the track. The outer surface of the track wheel 1 is provided with anti-slip protrusions 101, which can maintain stable traction in waterlogged areas or complex terrain, so that the robot can move smoothly to the drainage operation position. At this time, the external system starts the drainage pump 13 to work. The drainage pump 13 is installed under the frame 4, so that the water is sucked in by the drainage pump 13 and continuously discharged from the system through the drainage pipe to achieve the purpose of drainage. Meanwhile, in order to ensure long-term high-load operation, a cooler 10 is installed in the vehicle body 3. The heat generated by the generator 7 is exchanged through the cooler 10. A fan 11 is installed at the bottom of the cooler 10 to enhance airflow and thus improve heat dissipation efficiency. At the same time, the cooler 10 is connected to the water tank 12 to form a water-cooled circulation to further control the temperature and ensure the continuous and stable operation of the equipment. Throughout the process, the power system and drainage system are connected through a dynamic clutch (not shown in the figure) to achieve series control between the engine and the water pump. Power switching can be performed without stopping the machine, thus ensuring that the drainage operation is uninterrupted. At the same time, the track tension is kept stable by adjusting the adjusting wheel 210, so that it will not slip or derail due to power changes, ensuring that the robot can complete the drainage task stably and efficiently under various working conditions.

[0030] The winding assembly 5 includes a winding frame 501 and a drive motor 502. The winding frame 501 is rotatably mounted on the vehicle body 3, and the drive motor 502 is mounted on the vehicle body 3 and is used to drive the winding frame 501 to rotate.

[0031] During drainage operations, the drive motor 502 is remotely controlled to rotate the hose reel 501 to release the hose for drainage. After drainage is completed, the drive motor 502 is remotely controlled to rotate the hose reel 501 in the opposite direction, so that the hose reel 501 can be wound up by rotating in the opposite direction. This operation is convenient and reduces the workload of the operators.

[0032] It should be noted that the remote control can control the start and stop of the drive motor 502 and the hydraulic cylinder 221.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
