Engineering machinery railway running auxiliary device

Abstract

The invention provides an engineering machinery railway running auxiliary device. The device comprises a rack, two hydraulic motors and four lifting devices, wherein a plurality of rail wheels are rotatably installed on the lower portions of the two sides of the front end and the rear end of the rack respectively; the two hydraulic motors are in transmission connection with the rail wheels; and the four lifting devices are used for lifting the bottom surface of a vehicle frame of an excavator or the bottom surface of an axle of a loader. Two brake devices I and two brake devices II are arranged on the rack and used for braking. When the engineering machinery railway running auxiliary device is used, the excavator or the loader can be used to hang the engineering machinery railway running auxiliary device on a rail, then the excavator or the loader runs to the upper portion of the rail, the bottom faces of the vehicle frame of the excavator or the axle of the loader are supported by thelifting devices, and the excavator or the loader is lifted to be separated from the ground. Then the hydraulic motors are controlled to drive the engineering machinery railway running auxiliary device to lift the excavator or the loader to run on the rail, and the engineering machinery railway running auxiliary device is mainly suitable for railway emergency maintenance work.

Description

technical field [0001] The invention relates to an auxiliary configuration of construction machinery, in particular to an auxiliary device for construction machinery vehicles such as excavators or loaders whose inner wheelbase is larger than the total width of two rails of the railway, running on the railway. Background technique [0002] Current construction machinery such as excavators and loaders do not have the function of running on the railway. When the railway is damaged due to disasters such as landslides and mudslides, the above-mentioned construction machinery cannot pass because it does not have the function of running on the railway. When the railway travels to the emergency repair site, it can only be transported to the emergency repair site by road or railway truck. Some emergency repair sites are not accessible by road, so construction machinery such as excavators and loaders cannot be transported to the emergency repair site by road, and can only be transporte...

Problems solved by technology

[0002] Current construction machinery such as excavators and loaders do not have the function of running on the railway. When the railway is damaged due to disasters such as landslides and mudslides, the above-mentioned construction machinery cannot pass because it does not have the function of running on the railway. When the railway travels to the emergency repair site, it can only be transported to the emergency repair site by road or railway truck. Some emergency repair sites are not accessible by road, so construction machinery such as excavators and loaders cannot be transported to the emergency repair site by road, and can only be transported to the emergency repair site by railway trucks. However, there are many disadvantages in the transportation of railway wagons, such as the difficulty of loading and unloading excavators, loaders and bulldozers on the wagons, poor maneuverability and high cost. However, when the railway is damaged due to disasters such as landslides and mudslides, the railway circuit will often be damaged, which limits the use of railway freight cars.
