For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a channel device includes a rigid frame for connecting to a vehicle frame, and the installation area in the rigid frame is divided into a walking and maintenance area, a centralized lubricating oil barrel installation area and a hollow area; the walking and maintenance area includes a channel plate 2 for operators to step on; the centralized lubricating oil barrel installation area includes an oil barrel installation plate 5 for assembling at least one centralized lubricating oil barrel 8; the hollow area is arranged between the walking and maintenance area and the centralized lubricating oil barrel installation area, and can flow grease overflowing from the accessories installed on the centralized lubricating oil barrel 8 and the pipeline out of the channel device.

[0039] The above rigid frame is further described below.

[0040] Continue to refer to Figure 1 , Figure 2As shown, the rigid frame includes a channel body mounting plate 6, a channel enclosure 1 and a plurality of bottom fixing ribs 7; the side of the channel body mounting plate 6 is assembled on the frame by fasteners, and the top surface of the channel body mounting plate 6 is connected to the bottom surfaces of the channel plate 2 and the oil drum mounting plate 5; the channel enclosure 1 constitutes the remaining three sides of the rigid frame excluding the side of the channel body mounting plate 6, the upper edge of the channel enclosure 1 is higher than the channel plate 2 and the oil drum mounting plate 5, and the lower edge of the channel enclosure 1 is lower than the channel plate 2 and the oil drum mounting plate 5, thereby enclosing the channel plate 2 and the oil drum mounting plate 5 therein; a plurality of bottom fixing ribs 7 are arranged at intervals between the bottom surfaces of the channel plate 2 and the oil drum mounting plate 5 and the side surfaces of the channel enclosure 1 and the channel body mounting plate 6, fixing the channel body mounting plate 6, the channel enclosure 1, the channel plate 2 and the oil drum mounting plate 5 together.

[0041] It should be noted that the upper edge of the channel enclosure 1 is 70mm-140mm higher than the upper surface of the channel plate 2 to ensure the safety of people on the vehicle; the thickness and number of the bottom fixed ribs 7 are determined according to the length and area of ​​the actual channel device and the support weight above the channel device.

[0042] Further solutions, such as Figure 1 , Figure 3 As shown, a notch 12 is provided in the middle of the long side of the channel enclosure 1 , and a multi-step pedal 10 is installed on the outer side surface of the channel enclosure 1 below the notch 12 .

[0043] Further solutions, such as Figure 1 , Figure 4 As shown, a guardrail 9 is installed on the outer side of the passage enclosure 1 except for the position of the notch 12 through a guardrail mounting seat, and handrails 11 connected to the guardrail 9 are provided on both sides of the multi-step pedal 10. No shielding component is provided above the notch 12 or a hinged door is provided above the notch 12, so that it is used as the entrance of the passage device.

[0044] It should be noted that a guardrail 9 is installed around the passage device and a handrail 11 is installed at the pedal 10 to facilitate daily maintenance of the centralized lubricating oil barrel 8 and effectively ensure the safety of operators.

[0045] like Figure 1 As shown, the oil drum mounting plate 5 is not connected to the channel plate 2, and there is a 30mm-40mm interval between the two, forming a first hollow area of ​​the hollow area.

[0046] For further solutions, please refer to Figure 1 As shown, at least one through hole 13 is provided between the oil drum mounting plate 5 and the channel enclosure plate 1, and the through hole 13 forms a second hollow area of ​​the hollow area.

[0047] As can be seen from the above, by using the first hollow area and the second hollow area, the grease leaking from the grease pipeline of the lubricating oil barrel 8 will not be continuously accumulated on the mounting platform, and the cleaning of the grease pollution is also convenient.

[0048] The above-mentioned channel plate and mounting plate are further described below.

[0049] like Figure 1 , Figure 3 , Figure 4 As shown, the channel plate 2 is provided with a partition 4 extending upward in a manner perpendicular to the channel plate 2 at the end near the hollow area. The partition 4 cooperates with the hollow area to separate the walking and maintenance area from the centralized lubricating oil barrel installation area on the one hand, and prevent the overflowed grease from flowing to the walking and maintenance area on the other hand.

[0050] From the above, it can be seen that the channel device separates the walking and maintenance area from the centralized lubricating oil barrel installation area through the leakage area and the partition 4 between the oil barrel mounting plate 5 and the channel plate 2. The leakage area and the partition 4 effectively prevent the grease overflowing from the components and pipelines above the centralized lubricating oil barrel 8 from contaminating the vehicle and the walking and maintenance area.
