Description

Technical Field

[0001] The present invention relates to the field of maintenance and reinforcement of infrastructure such as expressways and intelligent control technology of engineering machinery, and in particular to an intelligent concrete material construction vehicle and a construction method thereof. Background Art

[0002] In recent years, along with the rapid development of society and economy, the construction of transportation infrastructure in my country has been changing with each passing day. At present, the mileage of expressways in my country has exceeded 130,000 kilometers, the mileage of tunnels has exceeded 20,000 kilometers, and there are about 800,000 bridges. The design life of these infrastructure structures is generally long, but with the continuous increase of traffic loads, environmental effects such as earthquakes and wind, corrosion effects, freeze-thaw damage, and the influence of various unfavorable factors such as material aging, expressways and bridges and other engineering structures will inevitably produce problems such as reduced bearing capacity, accumulated damage, and reduced structural durability, which seriously affect the safety of vehicles and personnel. Therefore, how to quickly strengthen and maintain the structure and improve the construction quality and speed of maintenance has become a major issue in relevant departments and social development.

[0003] At present, in the reinforcement construction of roads and bridges, bagged concrete dry mix, gravel, etc. are generally pulled to the site, equipped with mixers and pumping equipment. After the materials are unloaded from the car, the dry mix is ​​first added to the mixer manually, and then the appropriate amount of gravel and water are weighed according to the proportion, added to the equipment and mixed, and finally the mixed material is manually poured into the pumping equipment for construction. In some construction sites, there are even cases where materials are mixed manually with handheld mixers. Manual weighing usually leads to deviations in material usage, especially water usage. For concrete materials, if the water usage deviation is large, it will cause performance problems such as water seepage, segregation, and insufficient strength of the material, which seriously affects the quality of the material. Manual mixing will lead to problems such as insufficient mixing time, uneven mixing, and serious time-consuming and labor-intensive mixing, which will affect the progress and quality of the construction. In addition, after the construction is completed, the subsequent equipment cleaning and removal are quite troublesome, requiring a lot of manpower to complete, and it is very easy to have problems such as dirty and messy construction sites.

[0004] However, there are almost no effective methods to solve the above problems on the market. Therefore, developing a device or construction technology that can take into account material performance, construction speed, and construction quality has become an urgent problem to be solved and has great practical significance.

[0014] In a further design of the present invention, the pumping system is placed below or beside the stirring system, and the stirring system is provided with two discharge ports, one of which is connected to the pumping system, and after the material is stirred evenly, the stirring system can directly discharge the material into the pumping system for pumping construction. The other discharge port is used as a backup, and can be directly discharged to the on-site conveying system according to actual construction requirements.

[0015] In a further design of the present invention, the cleaning system is connected to a water tank and a mixer respectively, and after the construction is completed, an appropriate amount of water is controlled to enter the mixing system and the pumping system for cleaning.

[0016] In a further design of the present invention, the intelligent control system is custom-developed based on a PLC control system, and is equipped with an operating console and a microcomputer display screen to control the operation of all equipment on the vehicle.

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in more detail in combination with the preferred embodiments of the present invention. It should be pointed out that the described embodiment is only an embodiment of the present invention, which is exemplary and intended to be used to explain the present invention, and cannot be understood as a limitation of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The embodiments of the present invention are further described below in combination with the accompanying drawings.

[0025] like Figure 1-4 The intelligent concrete material construction vehicle shown in the figure first stores the concrete dry mix and gravel into the corresponding tank bodies through the feeding holes (14) and (15) on the top of the powder tank (1) and the aggregate tank (2), and at the same time fills the water tank (3) with water, and then drives the vehicle to the construction site. If there is no power supply on the site, the power generation system (13) is turned on.

[0026] According to the construction conditions on site and the optimal mix ratio of the required concrete materials, the relevant programs are set on the PLC control system (12), mainly including: 1) the delivery sequence, weight and error of the dry mix, gravel and water; 2) the mixing time and mixing speed of the materials; 3) the discharge speed of the materials after the mixing time is reached; 4) the pressure parameters of the pumping system; 5) the starting conditions of the second mixing cycle, etc.

[0027] After the program settings are completed, start the device and start working. Figure 2-4As shown, first, the dry mix enters the metering system (5) through the discharge screw (4) at the bottom of the powder tank 1. After reaching the set value, the discharge screw (4) stops working. The gravel enters the metering system (6) through the discharge screw (16) at the bottom of the aggregate tank (2). After reaching the set value, the discharge screw (16) stops working. Then the lifting system (6) enters the working state, and lifts the concrete dry mix and gravel into the mixing system (10). At the same time, the water pump (7) connected to the water tank (3) starts working and pumps water into the metering system (8). After reaching the set value, the water pump (7) stops working, and the water pump (9) starts to pump water into the mixer.

[0028] Then the mixing system (10) starts working and mixes according to the time and speed set by the program. After the set mixing time is reached, the material is discharged. If pumping is used at the construction site, the discharge speed needs to be set according to the power and flow rate of the pumping system (11). The mixer (10) discharges the material to the pumping system (11) through the discharge port (18) for pumping construction. The entire construction process is carried out continuously. If pumping is not required at the construction site, the mixer (10) directly discharges the material into the on-site conveying system through the discharge port (19) for construction.

[0029] After the construction is completed, the cleaning program is set, including the amount of water used for each cleaning, cleaning time, cleaning times, etc. After the program is set, the water is directly pumped into the mixing system for stirring and cleaning, and then enters the pumping system for cleaning. After the set cleaning times are reached, all equipment stops working, the entire construction process is completed, and the vehicle is driven away from the site.
