A kind of asphalt pavement comprehensive maintenance vehicle that can not only fry materials on site but also store materials in heat preservation

Abstract

The invention discloses a comprehensive asphalt pavement maintenance truck capable of performing site material frying and heat-preservation material storing. The comprehensive asphalt pavement maintenance truck comprises a chassis and a frame and also comprises a stock bin system, a stock bin lifting mechanism, a hydraulic grab bucket feeding system and a discharging device. The stock bin system can fry a mixed asphalt material and can also be in butt joint with an asphalt mixing station to achieve heat-preservation storage of the hot mixed asphalt material, the defect that stock bins of asphalt pavement maintenance trucks in the market are single in function and poor in environmental adaptability is overcome, the truck achieves multiple purposes in one, has strong climate adaptability and is efficient, capable of saving energy and environmentally friendly. The full-automatic hydraulic grab bucket feeding system can achieve accurate positioning, automatic grabbing, rotary feeding and accurate discharging of the mixed asphalt material in any region within the extensible rotation radius range of a suspension arm and is high in automation degree, large in feeding distance, wide in range, accurate and efficient. Discharging of the stock bin can be achieved by adopting a double-connecting-rod mechanism lifting the self-weight of the stock bin, and reversed discharging can be also achieved by adopting a helix which the stock bin is provided with.

Description

technical field [0001] The invention relates to a vehicle for comprehensive maintenance of asphalt pavement, in particular to a vehicle for comprehensive maintenance of asphalt pavement capable of frying materials on site and storing materials in heat preservation, and belongs to the field of road maintenance equipment. Background technique [0002] Various diseases such as potholes, cracks, wrapping, pockmarks, etc. often occur in the use of asphalt pavement. The asphalt pavement comprehensive maintenance vehicle is a kind of maintenance equipment specially used to deal with the above diseases. The asphalt pavement comprehensive maintenance vehicles on the market have the following disadvantages: 1. The silo has a single function and poor environmental adaptability. That is, when the asphalt mixing station is in operation, the on-site frying type asphalt pavement maintenance vehicle cannot dock with the asphalt mixing station, and cannot receive hot asphalt mixture; when th...

The asphalt pavement comprehensive maintenance vehicles on the market have the following disadvantages: 1. The silo has a single function and poor environmental adaptability

That is, when the asphalt mixing station is in operation, the on-site frying type asphalt pavement maintenance vehicle cannot dock with the asphalt mixing station and cannot receive hot asphalt mixture; when the asphalt mixing station is closed in winter, the thermal insulation storage type asphalt pavement The maintenance vehicle cannot realize the on-site frying of asphalt mixture; 2. The heating system uses a single heat source, and the heating efficiency is low. Heating with open flame or infrared radiation can easily cause scorching and aging of the asphalt mixture. The heat is not recycled and reused, resulting in waste of energy resources. There is no dust removal device for on-site frying, which causes environmental pollution; 3. The feeding device is mostly loaded by hand or with the help of a simple motor or wire rope, which is time-consuming and laborious; the feeding device with a high degree of automation controlled by an oil cylinder requires manual loading. , the feeding range is small, and the structure of the turning mechanism is complex, the load is large, and there are safety hazards; 4. The asphalt mixture transportation process is prone to cooling arching, segregation, discontinuous discharge, and material jams, etc., which cannot be done well. Fully meet the requirements of modern maintenance of asphalt pavement
