[0002] An amphibious excavator is a special-designed construction machinery that has the ability to operate in water and on land. This kind of excavator is usually applied to environments that require frequent switching of operations between water and land, such as river dredging, lake restoration, swamp construction, port engineering, etc. The forward movement of the amphibious excavator requires a traveling device for the amphibious excavator. The traveling device is usually divided into two types: crawlers and tires. The amphibious excavator designed with crawlers usually has good buoyancy and traction force, can provide sufficient buoyancy in water, and at the same time provide stable traction and operation ability on land.

[0003] However, the existing traveling device for amphibious excavators has the following disadvantages. Since the excavator for amphibious use works in water or on land, it usually comes into contact with silt and soil blocks. The silt and soil blocks will adhere to the wear-resistant blocks of the traveling device of the excavator. After a long adhesion time, it is not convenient to clean, which may cause inconvenience for the excavator to move forward and affect the working efficiency of the excavator. Therefore, it is necessary to improve the existing traveling device for amphibious excavators. Content of the Utility Model

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: a traveling device for an amphibious excavator, including a frame 1 and a crawler 3. A drive assembly 2 is installed at one end of the frame 1, and a driven assembly 10 is installed at the other end of the frame 1. The crawler 3 is sleeved outside the frame 1, the drive assembly 2 and the driven assembly 10. One side of the frame 1 is connected to a chassis 7, and both ends of the chassis 7 are fixed with side frames 8.

[0026] Please refer to Figures 1-5 , above the side frame 8, a transmission mechanism 6 is installed. One side of the transmission mechanism 6 close to the crawler 3 is connected to a scraper 5. The transmission mechanism 6 includes a tooth block 601, a connecting rod 602, a fixing frame 603, a gear 604 and a motor 605. A fixing frame 603 is fixed above the side frame 8. The inner side of the fixing frame 603 is slidably sleeved with a connecting rod 602, and one end of the connecting rod 602 is connected to the scraper 5. Tooth blocks 601 are arranged at equal intervals on one side of the connecting rod 602. A motor 605 is installed in the built-in groove of the side frame 8. Above the motor 605, a gear 604 is connected through a coupling, and the tooth block 601 and the gear 604 are meshed.

[0027] During specific implementation, since the excavator for amphibious use usually comes into contact with silt, the silt will adhere to the wear-resistant block 4 of the traveling device of the excavator. After a long adhesion time, it is not convenient to clean, which may cause inconvenience for the excavator to move forward and affect the working efficiency of the excavator. When the excavator stops moving forward, the motor 605 can be started to drive the gear 604 to rotate. The gear 604 is meshed and connected with the tooth block 601, so that the connecting rod 602 is pushed to both sides. At the same time, the connecting rod 602 slides inside the fixing frame 603, so that the connecting rod 602 pushes the scraper 5 to scrape above the crawler 3, and the silt adhered to the wear-resistant block 4 is pushed to the outside of the traveling device. By pushing or pulling the scraper 5 through the connecting rod 602, the silt on the traveling device can be quickly cleaned, improving the working efficiency of the traveling device of the amphibious excavator.

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figures 6-8 As shown in, there are evenly spaced installation mechanisms 9 on the outer side of the crawler 3. A wear-resistant block 4 is connected to the side of the installation mechanism 9 away from the crawler 3. The installation mechanism 9 includes a docking block 901, a fixing block 902, a sleeve rod 903, a fastening ring 904 and a docking groove 905. Evenly spaced fixing blocks 902 are fixed on the outer side of the crawler 3. A docking groove 905 is formed inside the fixing block 902. A docking block 901 is arranged inside the docking groove 905. The docking block 901 is connected to the wear-resistant block 4. Sleeve rods 903 are connected to both ends of the docking block 901. A fastening ring 904 is threadedly sleeved on the outer side of the sleeve rod 903. The cross-sectional shapes of the docking block 901 and the docking groove 905 are both "T" shaped.

[0029] During specific implementation, the wear-resistant block 4 on the traveling device of most amphibious excavators will be worn after a long service time and needs to be replaced. However, the wear-resistant block 4 is usually installed on the crawler 3 through multiple bolts, which is not convenient for quick disassembly. When the wear-resistant block 4 needs to be disassembled, the fastening ring 904 can be rotated to remove the fastening ring 904 from the sleeve rod 903, and then the wear-resistant block 4 is pulled to one side, so that the wear-resistant block 4 drives the docking block 901 to slide to one side in the docking groove 905, and the wear-resistant block 4 can be quickly disassembled from the fixing block 902 for replacement, improving the convenience of the traveling device of the amphibious excavator.

[0030] Working principle: When using the traveling device for the amphibious excavator, first, the driving component 2 and the driven component 10 drive the crawler 3 to rotate, driving the machine frame 1 to move forward on the ground and driving the excavator to the working area. When the machine frame 1 stops moving, the scraper 5 can be driven by the transmission mechanism 6 to scrape the silt or soil adhered to the wear-resistant block 4 to the outside of the crawler 3, facilitating the forward movement of the traveling device. When the wear-resistant block 4 is worn out more, the wear-resistant block 4 can be disassembled from the crawler 3 through the installation mechanism 9, improving the working efficiency and convenience of the traveling device for the amphibious excavator. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
