Problems solved by technology

[0006] The present invention mainly solves the problem in the prior art that in the past, the U-turn construction operation of the laying equipment is carried out through rail transportation, and the traction of a locomotive is used to carry out large-scale operation on the existing line through a triangular line with a small winding diameter, so as to realize the purpose of U-turn of the laying equipment. This construction method takes a long time and is inefficient, and at the same time occupies a large amount of freight resources, which seriously hinders the normal operation of the railway network and other technical problems; it provides an in-situ U-turn operation for laying equipment, which changes the previous construction method , a self-propelled turntable vehicle that releases operational pressure for railway freight and wins time for laying construction units

Embodiment

[0064] A self-propelled turntable car, characterized in that it includes a walking trolley 1 and a car body 2 arranged on the walking trolley 1, the car body 2 is provided with a rotary drive device 3 that can pass through the car body 2 Drive it to do the upper turntable body 4 of horizontal rotation. The traveling trolley 1 comprises a trolley frame 5 and four traveling wheel devices 6 arranged at the bottom of the trolley frame 5, the car body 2 is fixed with the trolley frame 5 by fixing bolts, and the trolley frame 5 is also provided with The frame 5 is vertically provided with at least two telescopic extension leg devices 7 . The traveling wheel device 6 includes a traveling wheel frame 8 and two traveling wheels 10 fixed on the traveling wheel frame 8 driven by a reduction motor 9 fixed on the traveling wheel frame 8 . The extended leg device 7 includes a single leg frame 11 and extended legs 12 fixed at both ends of the single leg frame 11 . At least two rotary row w...

Embodiment approach

[0069] Step 1. Vertical change rack:

[0070] Step 1.1. The distance between two hydraulic flip-mounting gantry frames is 25000mm. One is located at the front end of the car body, 9000mm from the front end, and the other is located at the rear end of the car body, 12000mm from the rear end. as follows Figure 4 shown.

[0071] Step 1.2. The foundation at the vertical replacement frame must be solid, the settlement of the foundation must not exceed the relevant standards, and at least two layers of sleepers should be placed.

[0072] Step 1.3. The two columns of the replacement frame are perpendicular to the horizontal plane, the verticality is ≤2 / 1000, the center of the replacement frame coincides with the center of the line, and the error is ≤10mm.

[0073] Step 2. The arm is separated from the car body, such as Figure 5 , Figure 6 and Figure 7 as shown,

[0074] Step 2.1. The bridge erecting machine is located at the track laying position, and the No. 0 column is r...

Abstract

The invention relates to a turntable vehicle, in particular to a structural improvement of a self-propelled turntable vehicle. The invention is characterized in that the self-propelled turntable vehicle comprises traveling trolleys (1) and a vehicle body (2) arranged on the traveling trolleys (1), an upper turntable body (4) which can be driven by a rotary driving device (3) to horizontally rotate on the vehicle body (2) is arranged on the vehicle body (2), and a traveling wheel device (6) with a sensor is installed at the lower part of the upper turntable body. Thereby, the invention has theadvantages that: 1. the design is reasonable, the structure is simple, the noise is low and the vehicle is very practical; and 2. the previous construction method is changed, the operation stress is released for railway freight and time is saved for the laying and erecting construction units.

Description

technical field [0001] The invention relates to a turntable car, in particular to the structural improvement of a self-propelled turntable car. Background technique [0002] In order to meet the needs of social and economic development, and meet the requirements of cargo owners and passengers for safety, accuracy, speed, convenience and comfort, railways in various countries have carried out large-scale modernization and technological transformation. [0003] From the perspective of the world, there are already more than ten national railway passenger trains with a maximum speed of 200 kilometers per hour. Among them, in 1996, Russia determined the maximum speed of passenger trains on existing railways to be 200 kilometers per hour; There are four levels of speed-up: 145 km / h, 177 km / h, 200 km / h, and 240 km / h. [0004] After six times of speed-up reconstruction, my country's railways have formed a nationwide express passenger transport network and a large-capacity freight ...
