Flexible transverse displacement platform for rail vehicles

Abstract

The invention discloses a flexible transverse displacement platform for rail vehicles. The flexible transverse displacement platform comprises a displacement platform body, a walking device, a left bearing stand column, a right bearing stand column, a left conical positioning pin, a right conical positioning pin, a left heavy load linear guideway, a right heavy load linear guideway, a synchronous connection device and a displacement hydraulic device; the bottom of the displacement platform body is connected with the walking device, the two ends of the top of the displacement platform body are provided with the left heavy load linear guideway and the right heavy load linear guideway respectively, and the bearing stand columns are connected with each other through the synchronous connection device; the top of the left bearing stand column and the top of the right bearing stand column are provided with the left positioning pin and the right positioning pin respectively; the displacement hydraulic device is arranged on the portion, at the left side of the right bearing stand column, of the displacement platform body. The flexible transverse displacement platform for the rail vehicles is simple in structure and light in weight and suitable for the mutually inverse conversion of the transverse displacement between a standard rail and a non-standard rail of various rail vehicles, the cost is saved, the operator number is decreased, and therefore operators can operate more conveniently.

Description

technical field [0001] The invention relates to a rail vehicle flexible lateral displacement platform, which belongs to the technical field of rail vehicle assembly equipment. Background technique [0002] The international railway gauge has various specifications such as 1000mm, 1067mm, 1435mm, 1520mm, 1676mm, etc. The equipment of domestic rail transit enterprises is suitable for the design and manufacture of the standard gauge of 1435mm. There are more and more orders for non-standard gauge vehicles. In the process of rolling off the wheels of rail vehicles, in view of the difference between foreign gauges and domestic standard gauges, subject to cost and plant environment, many manufacturers adopt the three-track laying transformation method to realize standard gauge at the same time. And the function of non-standard rail, which brings many difficulties to the assembly operation of the rail vehicle body and bogie connection, mainly as follows: (1) The rail vehicle body i...

[0002] The international railway gauge has various specifications such as 1000mm, 1067mm, 1435mm, 1520mm, 1676mm, etc. The equipment of domestic rail transit enterprises is suitable for the design and manufacture of the standard gauge of 1435mm. There are more and more orders for non-standard gauge vehicles. In the process of rolling off the wheels of rail vehicles, in view of the difference between foreign gauges and domestic standard gauges, subject to cost and plant environment, many manufacturers adopt the three-track laying transformation method to realize standard gauge at the same time. And the function of non-standard rail, which brings many difficulties to the assembly operation of the rail vehicle body and bogie connection, mainly as follows: (1) The rail vehicle body is huge and heavy, and it is difficult for large-tonnage hoisting equipment to achieve lateral movement accuracy Requirements, and will cause repeated hoisting, high production costs

(2) For the rail vehicles that have been assembled, the chassis is equipped with brake pipelines and signal cables, which are difficult to lift with a spreader and are easy to cause damage to the pipelines and cables

(3) Ordinary cranes can only realize the function of erecting vehicles, but cannot realize the conversion between standard rails and non-standard rails, making the assembly of the vehicle body and bogies difficult or even impossible

However, in the actual operation process, it is difficult to guarantee the accuracy requirements of the millimeter level in the hoisting of the car crane, so there are many safety hazards in the hoisting process. In order to be able to get off the car, a considerable number of personnel must be equipped to coordinate the operation at the same time

There will be big problems in this kind of installation process, not only the assembly quality is poor, the assembly efficiency is low, but also a lot of manpower, material resources, and financial resources are wasted, and even affect the connection between the car body and the bogie of the rail vehicle, and there will be safety hazards , affecting product quality
