A two-way traction trolley for a railway track bed operation device

Abstract

The invention provides a two-way traction trolley for a railway track bed operation device, which includes a trolley support (11), trolley wheels (10) are installed on both sides of the trolley support (11), and a frame bottom is installed above the trolley support (11). Beam (13), the front and rear of the trolley support (11) are respectively connected to the support frame by a drawbar, the front and rear of the trolley support (11) are equipped with a traction support fixing frame, and the drawbar and the trolley support (11) ) are connected by the traction support fixed frame, the trolley bracket (11) is connected with the frame bottom beam (13) by a hydraulic cylinder, and the frame bottom beam (13) and the trolley bracket (11) are also equipped with Depress cylinder (14). By controlling the flow supplied by each hydraulic cylinder, the towing car can be tilted up or down to meet the lifting or lowering of the towing car on the curved road section. By pressing down the cylinder, a vertical downward load can be applied to the towing car to ensure traction during operation. The stable operation of the trolley makes it difficult for the traction trolley to derail, thereby improving the quality of work such as sewage suction on railway track beds.

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...
