Four-supporting-point side bearing balancer for paving and erecting machine vehicle

Abstract

The invention relates to a four-supporting-point side bearing balancer for a paving and erecting machine vehicle. The four-supporting-point side bearing balancer for the paving and erecting machine vehicle is characterized in that the periphery of each core plate is provided with a hydraulic side bearing device; each hydraulic side bearing device comprises a cylinder body; the cylinder body is arranged in the inner part of a side beam in an inverted mode; the cylinder body is internally provided with an upper side bearing in a seal mode; the space between the upper side bearing and the cylinder body is internally used for pouring hydraulic oil; the cylinder body wall of the space is provided with a screw block and a pipe joint which are communicated with the space; a lower side bearing is arranged below the upper side bearing; the lower side bearing is arranged in a lower side bearing box; two vertically symmetrical hydraulic side bearing devices act as a first pair of hydraulic side bearing devices, and the other two hydraulic side bearing devices act as a second pair of side bearing devices; a pipe joint on one cylinder body of each pair of hydraulic side bearing devices is connected with a first oil pipe, and a pipe joint on the other cylinder body is connected with a second oil pipe; the first oil pipe and the second oil pipe are connected through a tee; tees in the two pairs of hydraulic side bearing devices are connected through a third oil pipe; oil circuits of the four hydraulic side bearing devices are connected integrally and are communicated; and the oil pipe between two cylinder bodies of the first pair of hydraulic side bearing devices is provided with a screw plug.

Description

technical field [0001] The invention relates to a bearing device, in particular to a four-point side bearing load balancing device for railway track laying machines and bridge erecting machines. Background technique [0002] The vehicle used for track laying machine and bridge erecting machine is one of the special vehicles, mainly composed of car body, bogie, air brake device, coupler buffer device, hand brake device and other parts. A large number of existing track-laying machines and bridge-erecting vehicles in my country use the front bogie as a five-axis integrated (or four-axis integrated) side bearing four-point structure, and the rear bogie uses a center plate load. The structural form of the combined four-axle bogie. The different bearing modes of the above-mentioned front and rear bogies not only ensure the stability and heavy load requirements during track laying and bridge erection operations, but also meet the adaptability of vehicles to the line during rail tra...

AI Technical Summary

Problems solved by technology

However, the front five-axis integrated (or four-axis integrated) bogie and the car body are carried by four side bearings to transmit the vertical force, and it is difficult to guarantee the contact surface of the four side bearings in the manufacturing process. On the same level, the axles of the bogie are unevenly loaded, causing hidden dangers to the safety of the vehicle during track laying and bridge erection operations of the laying machine, and reducing the dynamic performance of the vehicle during rail transportation
