Example Embodiment

[0076] The present invention will be described in detail based on Figures 1-12. The railroad turnout integral moving device moves the pre-paved turnout I horizontally to the position to be replaced. A number of guiding slide rails 42 are arranged within the horizontal movement range of the pre-paved turnout I, including at least 5-15 groups of mobile units, each group moving The unit is equipped with two switch-changing trolleys II, which are respectively arranged on the slide rails 42 at both ends of the two adjacent turnout sleepers (two equal-length turnout sleepers should be selected) of the pre-paved turnout I, that is, each slide rail 42 is equipped with two switch car Ⅱ. Each switch trolley Ⅱ is composed of three parts: hydraulic lifting device, horizontal moving block, and vertical adjusting block; hydraulic lifting device uses hydraulic device to lift or lower the switch, and horizontal moving block uses gear set variable force drive mechanism to complete horizontal mo...

Abstract

The invention relates to an integrally-moving device for railway turnout junctions, which solves the problems that a turnout junction rail jack, a rail car and a rail crane are needed in the existing railway turnout junction replacement method, the cost is high, transportation resources are occupied when vehicles run, a great amount of blocking time is used during replacement in fault removal, a great amount of labor and material resources are needed and the construction process is unsafe. In the integrally-moving device for railway turnout junctions, a turnout junction to be laid is integrally moved to a position to be replaced by a sliding rail, and a plurality of guide sliding rails are distributed in a transversely moving range of the turnout junction to be laid; the technical points are as follows: the device at least comprises 5-15 groups of moving units, each group of the moving units are provided with two turnout junction replacement dollies which are respectively distributed on sliding rails at two ends of each of two adjacent switch ties (preferentially, two switch ties with equal length) of the turnout junction to be laid, and each turnout junction replacement dolly consists of a hydraulic pressure lifting device, a transverse moving device, a longitudinal adjusting device. The device has the advantages of economy, safety, convenience and rapidness and the like.

Description

technical field [0001] The invention relates to a small-scale mechanical equipment for replacing railway turnouts, which is an integral mobile device for railway turnouts with the advantages of economy, safety, convenience and speed. Background technique [0002] With the development of social economy, train speed, axle load, traction fixed number and total passing weight are constantly increasing, and the service life of railway turnouts is shortened, so the replacement is becoming more and more frequent. The current railway turnout replacement mostly adopts the lateral movement method, which uses steel rails as slide rails, and inserts lateral movement pulleys between the pre-paved turnout steel rails and the slide rails to pull the turnouts into place laterally. Then, use the turnout lifter to lift the turnout and withdraw the lateral movement pulley and slide rail, place the longitudinal adjustment pulley under the turnout pillow, lower the turnout and make longitudinal ...
