Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] like Figures 1 to 6 As shown, the protective cover for the travel hydraulic system of this utility model for an ultra-large hydraulic excavator includes a travel hydraulic pipeline cover 2 and a travel motor cover 1. The travel hydraulic pipeline cover 2 is connected to the travel motor cover 1 by bolts, and is used to protect the travel hydraulic pipeline and the travel motor.

[0015] Furthermore, in the aforementioned protective cover for the travel hydraulic system of the ultra-large hydraulic excavator, the lower cover 11 of the travel motor includes a mounting plate 11-1, a first curved plate 11-2, a second curved plate 11-3, a vertical plate 11-4, a first reinforcing plate 11-5, a second reinforcing plate 11-6, a third reinforcing plate 11-7, a first threaded plate 11-8, a second threaded plate 11-9, and a retaining ring 11-10. A first through hole 11-1.1 is provided in the center of the mounting plate 11-1, and bolt holes 11-1.2 are provided around the first through hole 11-1.1. The bottoms of the first curved plate 11-2, the second curved plate 11-3, and the vertical plate 11-4 are perpendicularly welded to the mounting plate 11-1 around the first through hole 11-1. The first reinforcing plate 11-5 is welded between the outer side of the first bent plate 11-2 and the mounting plate 11-1. The second reinforcing plate 11-6 of the travel motor lower cover is welded between the outer side of the second bent plate 11-3 and the mounting plate 11-1. The third reinforcing plate 11-7 of the travel motor lower cover is welded to the inner side of the first bent plate 11-2, the second bent plate 11-3 and the vertical plate 11-4. The first threaded plate 11-8 is welded to one side of the top of the first bent plate 11-2 and the second bent plate 11-3 respectively. The vertical plate 11-4 has a second through hole 11-4.1 in the middle.

The retaining ring 11-10 is welded to the mounting plate 11-1 and is coaxial with the bolt hole 11-1.2. The retaining ring 11-10 is set in a semi-circular structure. During installation, the mounting plate 11-1 passes through the first through hole 11-1.1 to the travel motor, placing the travel motor inside the travel motor cover 1. The lower cover 11 of the travel motor is then fixed to the longitudinal beam 200 by bolts passing through the bolt holes 11-1.2. The top of the bolts is inside the retaining ring 11-10, which effectively protects the bolts from impact and wear from protruding stones on the ground. The travel hydraulic lines can enter the travel motor cover 1 through the second through hole 11-4.1 and connect to the travel motor.

[0016] Furthermore, in the aforementioned protective cover for the travel hydraulic system of the ultra-large hydraulic excavator, the upper cover 12 for the travel motor includes a third curved plate 12-1, a sealing plate 12-2, a cover plate 12-3, a reinforcing plate 12-4 for the upper cover of the travel motor, and a first lifting lug 12-5. The sealing plate 12-2 is welded to the bottom of the third curved plate 12-1, the cover plate 12-3 is welded to the top of the third curved plate 12-1, the reinforcing plate 12-4 for the upper cover of the travel motor is welded between the inner side of the third curved plate 12-1 and the sealing plate 12-2, and between the inner side of the third curved plate 12-1 and the cover plate 12-3, respectively, and the first lifting lug 12-5 is welded to the outer side of the third curved plate 12-1.

[0017] Furthermore, in the aforementioned protective cover for the travel hydraulic system of the ultra-large hydraulic excavator, the sealing plate 12-2 is fixedly connected to the first threaded plate 11-8 on the first curved plate 11-2 by bolts, and the cover plate 12-3 is fixedly connected to the first threaded plate 11-8 on the second curved plate 11-3 by bolts. Therefore, when the travel motor needs maintenance, the upper cover 12 of the travel motor can be separated from the lower cover 11 of the travel motor by removing the bolts connecting the first bent plate 11-2 and the second bent plate 11-3 to the first threaded plate 11-8. The upper cover 12 of the travel motor is effectively enlarged by welding the sealing plate 12-2 and the end plate 12-3 to the upper and lower ends of the third bent plate, which improves the operating space during maintenance. The first lifting lug 12-5 can be used to assist in the disassembly and assembly of the upper cover 12 of the travel motor.

[0018] Furthermore, in the aforementioned protective cover for the travel hydraulic system of the ultra-large hydraulic excavator, the lower cover 21 for the travel hydraulic pipeline includes a first side plate 21-1, a second side plate 21-2, and a reinforcing plate 21-3 for the lower cover of the travel hydraulic pipeline. The first side plate 21-1 and the second side plate 21-2 are welded perpendicularly at 90 degrees through the reinforcing plate 21-3 for the lower cover of the travel hydraulic pipeline. One end of the first side plate 21-1 and the second side plate 21-2 are fixedly connected to the second threaded plate 11-9 by bolts, and the other end of the first side plate 21-1 and the second side plate 21-2 are fixedly connected to the H-frame 100 by bolts. This can effectively protect the travel hydraulic pipeline between the H-frame 100 and the travel motor. After the first side plate 21-1 and the second side plate 21-2 are welded together in an L-shaped structure, they can effectively lift the drooping travel hydraulic pipeline while separating and protecting the travel hydraulic pipeline from the longitudinal beam 200.

[0019] Furthermore, in the aforementioned protective cover for the travel hydraulic system of the ultra-large hydraulic excavator, the travel hydraulic pipeline cover 22 includes a third side plate 22-1, a fourth side plate 22-2, a travel hydraulic pipeline cover reinforcing plate 22-3, and a second lifting lug 22-4. The third side plate 22-1 and the fourth side plate 22-2 are welded perpendicularly at 90 degrees to each other via the travel hydraulic pipeline cover reinforcing plate 22-3. The second lifting lug 22-4 is welded to the outside of the third side plate 22-1. One end of the third side plate 22-1 and the fourth side plate 22-2 are connected to the third side plate 22-1 by bolts. The two threaded plates 11-9 are fixedly connected. The other ends of the third side plate 22-1 and the fourth side plate 22-2 are fixedly connected to the H frame 100 by bolts. After the third side plate 22-1 and the fourth side plate 22-2 are welded together in an L-shape, the maximum area of ​​the walking hydraulic pipeline can be exposed when the upper cover 22 of the walking hydraulic pipeline is removed, providing operating space for maintenance personnel. After the lower cover 21 of the walking hydraulic pipeline and the upper cover 22 of the walking hydraulic pipeline are installed, a rectangular protective space can be formed to protect the walking hydraulic pipeline between the H frame 100 and the walking motor.

The upper covers for the travel motor and travel hydraulic lines allow for convenient and quick maintenance of the travel motor and travel hydraulic lines. The retaining ring effectively protects the lowest bolts from impacts and wear from protruding stones on the ground.
