Problems solved by technology
In the newly emerging milling machine integrated maintenance vehicle, the depth control still needs to be manually set, and the milling process cannot follow the change of the road surface or ground level, causing the milling machine to break away from the ground and cause resonance or vibration. In severe cas

Embodiment Construction
[0023] Below in conjunction with embodiment the present invention is described in further detail:
[0024] A milling floating control system such as Figure 1-3 As shown, it includes a depth oil cylinder 20 and a pressure reducing valve 18 arranged on the milling shell 11, the depth oil cylinder 20 is connected with the hydraulic drive device through the pressure relief valve 18, and the piston rod of the depth oil cylinder 20 is connected to the milling machine The casing 11 is hinged, and the milling casing 11 rotates downward around a casing rotating shaft 21 provided inside it to be close to the ground. Such as figure 2 As shown, the hydraulic oil of the motor 9 in the milling device 7 enters the rod cavity of the deep oil cylinder 20 after the oil pressure of the P1-A3-B3-A2 road is adjusted to the preset pressure value by the pressure reducing valve 18 to generate a constant pressure. Pulling force, the pulling force acts on the milling shell 11 through the piston rod...

The invention discloses a milling and planing floating type control system and a multifunctional pavement maintenance truck with the milling and planing floating type control system and belongs to thefield of pavement maintenance machineries. The milling and planing floating type control system comprises a milling and planing device, a depth oil cylinder and a pressure reduction valve, wherein the depth oil cylinder and the pressure reduction valve are arranged on the milling and planing device. The depth oil cylinder is connected with the hydraulic system through the pressure reduction valve. A piston rod of the depth oil cylinder is hinged to a milling and planing shell. The piston rod retracts to drive the milling and planing shell to rotate downward around a shell rotating shaft arranged in the milling and planing shell to be tightly attached to the ground. The invention further relates to a boom system, the milling and planing floating type control system, a hydraulic system, a dust removal system and the multifunctional pavement maintenance truck with the milling and planing floating type control system. The milling and planing floating type control system is reasonable in design, simple and practical, the milling and planing machine shell is tightly attached to the ground in the milling and planing construction process, so that the efficiency of the dust removal systemis guaranteed; extension of the bulge milling function is achieved, the adaptability to the ground during milling and planing construction is good, and the milling and planing floating type control system has a high automation level, greatly lowers the labor intensity of sanitation workers, has a remarkable environment protection effect, significantly improves social benefits and has broad application prospect.
Description
technical field [0001] The invention relates to the field of road surface maintenance machinery, in particular to a milling floating control system and a multifunctional road surface maintenance vehicle. Background technique [0002] There are generally two ways to organize and implement the pavement maintenance industry. One is a traditional independent and decentralized maintenance fleet, and the other is a multi-functional integrated road maintenance vehicle. The maintenance team needs a variety of professional equipment such as transport vehicles, material pulling vehicles, milling and cutting machines, pavers, and road rollers. Each equipment is equipped with 2-3 people, which is labor-intensive, low construction efficiency, and high cost. The multi-functional maintenance vehicle adopts an integrated structure, which realizes advanced one-stop operation, and processes such as positioning, mixing, paving and compacting are solved at one time, which shortens the time and...
