Small-sized automatic hydraulic railway line tamping car

Abstract

The invention relates to a small-sized automatic hydraulic railway line tamping car, belonging to the field of railway line maintenance equipment. The small-sized automatic hydraulic railway line tamping car is characterized by comprising tamping mechanisms (5) and a travelling chassis (1), wherein travelling mechanisms are respectively arranged at the lower parts of the front side and the rear side along the travelling direction of the travelling chassis (1); the upper part of the travelling chassis (1) is divided into a front area and a rear area by taking the travelling direction as a benchmark; the two groups of tamping mechanisms (5) parallel to a railway line sleeper are respectively arranged at the left side and the right side of the front area; two groups of rail clamping mechanisms (3) are respectively arranged at the front side and the rear side of each group of tamping mechanism (5); a travelling down mechanism (4) capable of driving a whole machine to go up and down and rotate is arranged in the middle of the travelling chassis (1). The small-sized automatic hydraulic railway line tamping car is electromechanical integrated artificial intelligent equipment, and all operations such as transferring the equipment, automatically tamping and enabling the equipment to travel up and down can be realized by one person, so that not only is manpower greatly saved, but the working quality is also improved; the small-sized automatic hydraulic railway line tamping car has little interference to driving, and realizes the industrial upgrading of railway line turnout tamping operation from mechanization to automation.

Description

technical field [0001] The utility model relates to a small automatic hydraulic railway line compacting car, which belongs to the field of railway line maintenance equipment. Background technique [0002] The function of the ballast on the ballasted railway line is to carry the load transmitted to the sleeper when the train is running, and to stabilize the position of the sleeper on the railway line. These two functions are realized by utilizing the friction between ballast and gravel Yes, the greater the density of the ballast laid on the railway line, the better the stability of the railway line, but due to the different loads, the ballast density under the railway line sleeper is different from that of other parts. The railway line After the maintenance and compaction operation, the ballast in the sleeper box becomes looser due to the disturbance of the compaction equipment, resulting in a larger gap in ballast density under the pillow and between the pillow box, and the ...

Problems solved by technology

[0002]The function of the ballast on the ballasted railway line is to carry the load transmitted to the sleeper when the train is running, and to stabilize the position of the sleeper on the railway line. These two functions They are all realized by using the friction between the ballast gravel. The higher the density of the ballast laid on the railway line, the better the stability of the railway line. However, due to the different loads, the track under the railway line sleeper Ballast density is different from that of other parts. After railway line maintenance and compaction, the ballast in the sleeper box part becomes looser due to the disturbance of the compaction equipment, resulting in a larger gap in ballast density between the pillow box and the pillow box. , the density difference between the ballast arrangement under the pillow and the pillow box is an approximately vertical interface type. On both sides of this vertical interface, the ballast density difference is very large. Ballast tamping operation project, but due to lack of corresponding special equipment, this operation has not been realized

[0003]After the introduction of large-scale road maintenance machinery from abroad, the compactness of the ballast arrangement between the pillow and the pillow box is even greater due to the strong force of the compacting clamp of the large-scale compaction truck. Large, in order to reduce the unevenness of the subsidence of the railway line rolled by the train after the tamping operation, there is a special line stabilizing car in the large-scale road maintenance machinery. The line is stabilized. The stabilization work is to implement a high-frequency vibration on the railway line by the stabilizing car. On the one hand, this high-frequency vibration can increase the density of the loose ballast in the pillow box under high-frequency vibration. On the other hand, it can make the pillow The density of the lower ballast has a uniform decrease, which makes the density interface of the ballast arrangement under the pillow and between the pillow box somewhat relaxed, but this operation method reduces the compaction effect of the large compactor
