Pavement milling machine and operating method thereof

Abstract

The invention discloses a pavement milling machine and an operating method of the pavement milling machine. The pavement milling machine comprises a milling depth displaying and leveling device, support oil cylinders (4), wheel installing frames (5), a machine frame (8) and milling drums (7) arranged below the machine frame (8), wherein the wheel installing frames (5) are used for supporting the machine frame (8) through the support oil cylinders (4); the milling depth displaying and leveling device comprises a depth simulating controller (1) and coiled ropes (2), wherein the coiled ropes (2) are coiled in the depth simulating controller (1), and extends outside and fixedly connected to the wheel installing frames (5); and the depth simulating controller (1) is used for detecting and displaying the variable of the extending length of the coiled ropes (2), and is arranged on the machine frame (8) so as to move along with the lifting of the milling drums (7). With the adoption of the pavement milling machine, the mechanical milling depth displaying and leveling device can be manually adjusted or zeroed; and the pavement milling machine is conveniently operated, and specifically the pavement milling machine is convenient for an operator to mill through a plurality of cutters, therefore, higher milling precision can be obtained, and high smoothness can be ensured.

Description

technical field [0001] The invention relates to a road surface milling machine, in particular to a road surface milling machine capable of accurately displaying the milling depth and a milling operation method thereof. Background technique [0002] Such as figure 1 and figure 2 As shown, in the common small road milling machines used for small-area maintenance and milling construction of municipal roads, the scale 10 with scale (circle enlarged part) is generally installed directly on the rear leg of the milling machine during milling operations. In the outer sleeve of the oil cylinder 4, when the scale 10 is installed according to certain installation requirements (that is, on a flat ground, when the milling drum 7 is lowered to even contact with the ground, the extended scale value of the scale 10 is 0), after the installation is completed, The milling depth is directly reflected on the protruding scale of the scale 10, that is, as the milling deepens, the scale on the ...

AI Technical Summary

Problems solved by technology

It is obviously difficult for the operator to visually refer to the scale scale 10, which is inconvenient to operate, and because the accuracy of the scale of the scale 10 is not enough, although the milling can be flat within the milling width when milling the first cut, but when milling the second cut, it passes through the scale. There will also be errors in the reading calculation of the milling depth of the second knife, which makes it difficult to connect the milling road surface of the second knife with the milling surface of the first knife
