Embodiment Construction

[0026] The present invention will be further explained below in conjunction with the accompanying drawings.

[0027] A hydraulic control system for a microwave-heated asphalt pavement hot-in-place regeneration device, such as Figure 1-3 As shown, the in-situ heat regeneration device for microwave heating asphalt pavement includes a main frame, a space adjustment device and a heating device. The main frame 1 is used to carry all heating devices and space adjustment devices, and bears most of the weight. Therefore, the steel plate is used as the manufacturing material, and the main frame with steel as the casting material has sufficient load-bearing rigidity and load-bearing strength, so no compression will occur Deformation situation. The whole outside of the main frame is provided with a metal shielding net, and the bottom of the main frame is equipped with a universal wheel 3 with locks. The top of the main frame includes two first sliding guide rails 8 that are parallel t...

Abstract

The invention discloses a hydraulic control system for a microwave heating asphalt pavement hot in-place recycling device. The hot in-place recycling device comprises a main frame, a space adjusting device and heating devices. Universal wheels with locks are arranged on the bottom of the main frame, the space adjusting device comprises three independent sets of three-way electric- drive adjustmentstructures, and each set of the three-way electric-drive adjustment structures is connected with a set of heating devices. The hydraulic control system uses a hydraulic pump as the power source and adopts the hydraulic control system to realize the movement control of heating cavities along X axis, Y axis and z axis, the artificial cumbersome operation is simplified, and the labor intensity of workers is reduced; and at the same time, the influence of experience and physical strength on the microwave heating effect during manual adjustment of the heating cavities is avoided, the same horizontal plane is always maintained between different heating cavity opening faces, and it is ensured that the coupling effect can be always optimal.

Description

technical field [0001] The invention belongs to the technical field of microwave thermal regeneration of asphalt pavement, and in particular relates to a hydraulic control system of an in-situ thermal regeneration device for microwave heating of asphalt pavement. Background technique [0002] In recent years, with the vigorous development of highway traffic construction, asphalt concrete has been widely used in highway construction due to its excellent road performance and stable quality. By the end of 2012, more than 4 million kilometers of roads in China had been completed and opened to traffic, of which 95,000 kilometers were high-grade roads and sub-high-grade roads dominated by asphalt concrete pavements, ranking second in the world after the United States. Visible asphalt Concrete pavement is the main structural form of Chinese highway pavement. China began to build highways with asphalt pavements in the 1980s, and the general design life of asphalt pavements is 15 to...
