[0002] The crane refers to the multi-action hoisting machinery for vertically lifting and horizontally transporting heavy objects in a certain range, also known as a crane. The walking wheel set on the crane mainly plays a role in horizontal movement, and is driven by a motor to drive the walking wheel to roll on the track to move horizontally during work.

[0003] Among them, due to long-term work, a large amount of oil stains will be attached to the track. At this time, in order to avoid the movement of the walking wheel set being blocked, a shovel plate is generally installed on the walking wheel set to shovel off the oil stains to achieve the purpose of cleaning the track. After shoveling, in order to reduce the wear between the track and the walking wheel set, it is also necessary to apply lubricating oil on the track.

[0010] Preferably, the lower end of the fixed column passes through the upper end of the guide plate base, the lower end of the fixed column is tightly pressed on the folding tooth plate, the fixed column is slidingly matched with the guide plate base, the upper end surface of the folding tooth plate is provided with a fixing hole, the fixing hole is aligned with the fixed column, the side front of the track frame is fixedly installed with a folding top frame, the folding top frame is aligned with the folding tooth plate, the side rear of the track frame is fixedly installed with a reset inclined frame, and the reset wheel is aligned with the reset inclined frame.

[0011] Preferably, the outer surface of the connecting shaft is rotatably installed with a groove base, the lower end of the groove base is fixed with the walking wheel set, the rear end upper edge of the lubricating oil tank extends with an extension lug, the end of the extension lug is embedded on the connecting shaft, the outer surface of the fixed column is slidingly installed with a fixing sleeve, the fixing sleeve is fixed with the guide plate base, the outer surface of the fixed column is coaxially embedded with a lug ring, the lug ring is slidingly installed in the inside of the fixing sleeve, the outer side of the fixed column is wound with a compression spring, one end of the compression spring is fixed with the inside top surface of the fixing sleeve, and the other end of the compression spring is fixed with the upper end of the lug ring.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] 1. When the traveling wheel assembly rolls forward on the track frame, the V-shaped shovel head will scrape off the oil stains on the track frame. At the same time, the lubricating oil in the lubricating oil tank drips from the oil outlet at the bottom onto the track frame after the oil stains have been removed, and is then spread by the brush body, so that the lubricating oil is evenly attached to the track frame. This process does not require manual application by workers, effectively reducing the labor intensity of workers and improving work efficiency.

[0015] 2. When the traveling wheel assembly is about to reach the end of the track frame, the retractable toothed plate will abut against the retractable top frame, keeping the retractable toothed plate stationary. At this time, the traveling wheel assembly continues to move forward. During this process, the retractable gear rolls on the retractable toothed plate to drive the connecting shaft to rotate, thereby causing the lubricating oil tank and V-shaped shovel head to flip over to the top of the traveling wheel assembly. At this time, the fixing column is pushed out by the pressure spring and inserted into the fixing hole on the retractable toothed plate to fix the flipped lubricating oil tank and V-shaped shovel head, so that they are detached from the track frame. This is to prevent the V-shaped shovel head from damaging the lubricating oil layer during the movement of the traveling wheel assembly. At the same time, when the lubricating oil tank flips over to the top of the traveling wheel assembly, its bottom will be in an upward position, so that the lubricating oil inside the lubricating oil tank will no longer be discharged, thus avoiding the phenomenon of continuous discharge of lubricating oil and waste.

[0016] 3. During the rotation of the lubricating oil tank, the top shell wheel will press against the traveling wheel assembly to support the protective tooth plate. Then, the lubricating oil tank continues to rotate upwards towards the traveling wheel assembly. At this time, the protective tooth plate will gradually move under the support of the traveling wheel assembly, thereby driving the protective gear to rotate. This allows the protective shell at the end of the housing shaft to rotate towards the bottom of the lubricating oil tank and engage with the protective plate. The protective shell and protective plate are used to cover the brush body to prevent dust and other contaminants from adhering to the brush body and causing lubricating oil contamination during application.
