Technical Field

The utility model relates to an excavator technical field particularly, relates to an excavator railway gondola car walking loading and unloading is with raising structure.

Background

An excavator, also known as an excavating machine (excavating shovel), is an earth moving machine that excavates material above or below a bearing surface with a bucket and loads the material into a transport vehicle or unloads the material to a stockyard.

The materials excavated by the excavator mainly comprise soil, coal, silt, soil subjected to pre-loosening and rocks. In view of the development of construction machines in recent years, the development of excavators is relatively fast, and the excavator has become one of the most important construction machines in construction.

The common excavator structure comprises a power device, a working device, a swing mechanism, a control mechanism, a transmission mechanism, a walking mechanism, auxiliary facilities and the like, wherein the transmission mechanism transmits the power of an engine to executing elements such as a hydraulic pump, a hydraulic cylinder and the like through the hydraulic pump to push the working device to act, so that various operations are completed.

The excavator structure comprises a lower mechanism and an upper mechanism, wherein the lower mechanism of the excavator comprises a left walking frame, a right walking frame and a middle frame, the middle frame is rigidly connected with the left walking frame and the right walking frame, a rotary support is arranged on the middle frame, and the upper mechanism is rotatably arranged on the rotary support. The upper mechanism circumferentially rotates on the rotating support, and the travelling mechanism moves below the upper mechanism; however, the design of the excavator cannot be adapted to the railway train track for operation, and the excavator is extremely inconvenient to use. Therefore, in order to meet the requirement that the excavator works on the railway train track, a lifting structure is produced, and the lifting structure can improve the working height of the excavator matched with a train carriage. When the excavator structure is used for shoveling coal cinder, the coal cinder is not easy to clean due to the fact that a bucket of the excavator is large in size.
