Description

TECHNICAL FIELD

[0001] The utility model relates to the urban track bed construction field especially is concerned with a kind of urban track sleeper square auxiliary tool. BACKGROUND

[0002] In the process of the continuous advancement of urbanization in China, urban track plays a very key role. For the field of urban track bed construction, whether the sleeper can be accurately positioned directly relates to the quality level and the safety degree of operation of track. At present, there are various sleeper construction positioning methods, but all have certain defects, which are difficult to meet the requirements of high precision and high stability of track construction.

[0003] One of the common construction methods is to use a right-angle ruler to mark the sleeper edge line, to mark the edge line position on the rail surface with the basic strand fastener edge as the reference, and to mark another strand edge line with a square ruler. The line is drawn to the rail bottom edge with a right-angle ruler, and the sleeper is pried to coincide with the rail bottom edge mark line by removing the T-shaped bolt. Then, the square ruler and the line hammer are used to conform, and the error that may occur when the right-angle ruler is drawn is checked. The main construction process flow is: basic strand mark line → square ruler mark opposite mark line → fastener removal → sleeper movement → fastener installation → position conformity acceptance. However, this method has many problems. First, the operation error of the sleeper position mark line will affect the final sleeper position. Second, the positioning mark line is slow in work efficiency and lacks precision. Third, the process of using sleeper square line hammer review is complicated, and errors are likely to occur during the operation process, which affects the final sleeper position. In addition, the long sleeper type track bed has a large proportion in each project, which leads to a large amount of time consumption in the construction process and the inspection process.

[0004] Another construction method is to use a large-scale ruler to mark the sleeper spacing on both sides of the rail bottom edge, and to pry the sleeper to coincide with the rail bottom edge mark line by removing the T-shaped bolt. Then, the square ruler and the line hammer are used to conform, and the error that may occur when the steel tape is drawn is checked. The main construction process flow is: basic strand mark line → square ruler mark opposite mark line → fastener removal → sleeper movement → fastener installation → position conformity acceptance. It should be noted that this method is mainly suitable for straight sections and cannot be operated in curved sections. Moreover, when using the steel tape to draw the mark line, the starting point scale control is manually operated, which is easy to produce errors, resulting in the misplacement of all sleepers within one foot range. Similarly, due to the large proportion of long sleeper type track bed in each project, a large amount of time is consumed in the construction process and the inspection process. This method requires more construction personnel, and the professional and technical requirements for the construction personnel are high.

[0005] In summary, the existing sleeper construction positioning method is difficult to meet the requirements of efficient, high-precision, wide applicability and low-cost track construction, and it is necessary to develop a new sleeper positioning technology to overcome the defects of the existing technology.
