Mortar vehicle for concrete and asphalt

Abstract

The invention relates to a mortar vehicle for concrete and asphalt, comprising a bottom disc and upper components arranged on the bottom disc; the upper components comprise an assembly for weighing and charging dry powder, an assembly for measuring and charging asphalt, an assembly for measuring and charging water, an assembly for measuring and charging additives, an assembly for measuring and charging P emulsion, an assembly for a stirring main machine, an assembly for a mortar grouting plate, a power system and a control system; the two sides of a dry powder delivery screw machine in the assembly for weighing and charging dry powder are provided with a first asphalt storing tank and a second asphalt storing tank; the two sides below a dry powder storage bin are respectively provided with a third asphalt storing tank and a P emulsion storing tank in the assembly for measuring and charging P emulsion; three asphalt storing tanks are communicated to form an asphalt storing tank in the assembly for measuring and charging asphalt; and a water tank and a water pump in the assembly for measuring and charging water and an air reservoir in the power system are fixed on the bottom disc below the upper components. The mortar vehicle has the advantages of compact structure, ingenious layout, accurate measurement and wide application range and the like, can produce mortar with high modulus of elasticity and also can produce mortar with low modulus of elasticity.

Description

technical field [0001] The invention mainly relates to the field of mortar equipment, in particular to a cement asphalt mortar truck. Background technique [0002] Ballastless track construction is a new type of high-speed railway construction technology that has emerged in recent years. The ballastless track system consists of track bearing plates connected to each other in the longitudinal direction. On the subgrade, the track bearing slab is laid on the hydraulic concrete bearing layer or laid on the asphalt concrete bearing layer. On bridges, the track bearing slab is laid on the base concrete slab. After the track bearing plate is laid, the calibration system is used for fine adjustment. After fine adjustment, there is a certain gap between the track bearing plate and the base, which needs to be filled with a special cement asphalt mortar material. This cement asphalt mortar material includes three main types, namely high-strength and high-elastic-modulus mortar, hig...

AI Technical Summary

Problems solved by technology

Due to the high requirements on the proportioning accuracy of P emulsion, the existing mortar batching metering and feeding conveying system is not suitable for P emulsion supply and proportioning

In addition, there are many supporting equipment in the existing mortar truck, and various mechanisms have been arranged in a better position, but the space of the carriage is limited, and the layout is very cramped

In the case of multiple sets of existing mortar batching metering and feeding conveying systems, the cabin is already very crowded, and it is impossible to arrange the same structure of feeding and proportioning systems

Therefore, when the P emulsion needs to be supplied and proportioned, the existing system in the prior art cannot be borrowed, and a new liquid ingredient metering and feeding delivery system can only be designed on the basis of optimizing the space layout of the carriage to Meet the requirements of feeding and proportioning of various liquid ingredients, especially P emulsion

[0006] It can be seen that the existing mortar truck cannot supply and mix P emulsion, and it cannot produce low-strength and low-elasticity mortar, let alone track Loading board filling board
