Ballastless track panel fine adjustment machine and transmission shaft thereof

Abstract

The invention relates to the technical field of track construction, and provides a ballastless track panel fine adjustment machine and a transmission shaft thereof. The transmission shaft comprises asleeve, an inserting piece and a spring, wherein the inserting piece is arranged in the first end of the sleeve in a penetrating mode, the inserting section of the inserting piece and the interior ofthe sleeve form clamping connection in the circumferential direction, and a connecting piece is arranged at the extending end of the inserting piece. The spring sleeves the periphery of the transmission shaft, two ends of the spring are respectively connected with the sleeve and the connecting piece, in use, the connecting piece can stretch out and draw back along the length direction of the transmission shaft under the action of the spring, connection with an elevation screw rod or a transverse rotating shaft of the track panel is facilitated, and simultaneously connection effect is enhancedthrough elasticity of the spring. The ballastless track panel fine adjustment machine comprises the main frame, the vertical adjustment assembly and the transverse adjustment assembly, the adjustmentprocess is automatically carried out, the manual participation degree is low, the labor cost is saved, and the construction cost is reduced; the multiple ballastless track fine adjustment machines canbe controlled at the same time and adjusted independently, the automation degree is improved, the adjustment precision is high, and the construction speed is high.

Description

technical field [0001] The invention relates to the technical field of track construction, in particular to a ballastless track row fine adjustment machine and a transmission shaft thereof. Background technique [0002] Ballastless track refers to the track structure that uses concrete, asphalt mixture and other integral foundations to replace the loose-grained gravel track bed, also known as ballastless track, which is an advanced track technology in the world today. Among them, the double-block ballastless track is one of the most widely used ballastless track structures for high-speed passenger dedicated lines at home and abroad. [0003] At present, ballastless track passenger dedicated lines mostly use CRTSI double-block ballastless track, with a design speed of 350km / h. The safety, smoothness and comfort of high-speed train operation must be supported by good track geometry. Track fine adjustment is the key link of track precision control. According to the measurement...

Problems solved by technology

The manual adjustment method not only requires a lot of manpower and wastes labor costs, but also the accuracy is easily affected by human factors, and the consistency of adjustment accuracy cannot be guaranteed.

[0008] (2) It is adjusted through some complex mechanical equipment. When in use, the transmission shaft is driven to the set position by the complex transmission equipment, and then fine-tuned so that it can be connected with the elevation screw or the horizontal rotation shaft for further adjustment. However, This kind of mechanical equipment has complex structure, high equipment cost, and requires precise control of the position of the drive shaft, complex technical support, and low work efficiency
