Problems solved by technology

[0007] However, due to the complex working conditions of milling the circular road surface around the manhole cover, the straight shoulder road surface and the slope road surface, as well as the functions of milling depth control and material collection, the control, transmission and structure of the small wheel milling machine are very difficult. Complicated, large in size and high in cost

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The road surface milling machine of the present invention adopts a split structure, including an upper body of the milling machine and a lower body of the milling machine.

[0023] figure 1 It is a structural schematic diagram of the milling machine upper body of the road milling machine of the present invention.

[0024] pass below figure 1 The milling machine upper body of the road surface milling machine of the present invention is described in detail.

[0025] like figure 1 As shown, the upper body of the milling machine includes from top to bottom: a hydraulic power system 11, a support plate 12, a guide device 13, a fixed plate 14, a mechanical rotary system 15, and a hydraulic milling system 16. One end of the fixed plate 14 is fixed with a hydraulic The rotary system 17 is driven, and the hydraulically driven rotary system 17 cooperates wit...

Abstract

The invention discloses a pavement milling machine which comprises an upper milling machine body and a lower milling machine body, wherein the upper milling machine body comprises a fixed plate, a hydraulic driving and rotating system is fixed at one end of the fixed plate, a guiding device is arranged at the upper end of the fixed plate, a mechanical rotating system is arranged at the lower end of the fixed plate, a supporting plate is arranged at the upper end of the guiding device, a hydraulic power system is arranged at the upper end of the supporting plate and is matched with the mechanical rotating system through a gear, a hydraulic milling system is matched at the lower end of the mechanical rotating system, the lower milling machine body comprises a support body and a hydraulic lifting device, and the support body is also provided with a guiding hole matched with the guiding device. The pavement milling machine is in a split structure, reduces the complexity of mechanical and hydraulic driving, has a simple structure and low cost, is convenient to install and use, and has a better application prospect in using environments with complex working conditions such as a circular pavement around a milling well cover, a linear pavement of a road shoulder, a slope pavement and the like.

Description

technical field [0001] The invention relates to a road surface milling equipment, in particular to a road surface milling machine for milling the road surface around the road manhole cover. Background technique [0002] With the development of China's highway transportation, the mechanical maintenance operation method with milling machine as the main equipment has been widely used on China's highways. The milling machine is mainly used for the excavation and renovation of roads, urban roads, airports, freight yards, parking lots, etc., excavating road pits and grooves, removing road congestion, oil waves, reticulation, ruts, etc. It can be used for napping of cement pavement and so on. Due to the high mobility and high efficiency of the equipment, the milling depth is easy to control, making the road maintenance construction process simple and efficient. [0003] At present, milling machines are divided into cold milling and hot milling according to different milling proce...
