Two-way trailer wagon for railway ballast bed operation device

Abstract

The invention provides a two-way trailer wagon for a railway ballast bed operation device. The trailer wagon comprises a wagon support (11), wagon wheels (10) are installed on the two sides of the wagon support (11), a frame bottom beam (13) is installed above the wagon support (11), the front and the rear of the wagon support (11) are respectively connected with a supporting frame through traction rods, the front and the rear of the wagon support (11) are respectively provided with a traction supporting and fixing frame, the traction rods are connected with the wagon support (11) through the traction supporting and fixing frames, the wagon support (11) and the frame bottom beam (13) are connected with hydraulic cylinders, and a downward-pressing cylinder (14) is further installed between the frame bottom beam (13) and the wagon support (11). By controlling the feeding flow of each hydraulic cylinder, the trailer wagon can be obliquely lifted or descended so as to meet the requirement that the trailer wagon needs to be lifted or descended on a curved road segment, plummet loads can be applied to the trailer wagon through the downward-pressing cylinder, running stability of the trailer wagon in operation is guaranteed, the trailer wagon is not prone to running off rails, and therefore the quality of operation such as dirt suction of railway ballast beds can be improved.

Description

technical field [0001] The invention relates to a traction trolley, in particular to a bidirectional traction trolley which can be used for a railway track bed operating device. Background technique [0002] When working on the railway track bed, different operating devices are required, such as track bed sewage suction device, track bed snow removal device, etc. These operating devices need to be installed on a trolley that is easy to lift or lower, can pass through curves, and can run smoothly. Foreign tractors used for railway track bed operations often have problems such as jumping or derailment during the operation process, which affects the quality and efficiency of the operation and increases the maintenance cost of railway lines. The requirements for operating speed and quality are getting higher and higher, and the devices in the prior art are difficult to meet such requirements. Contents of the invention [0003] It is set in the present invention that the trans...
