Running deviation correcting device and rail-type engineering machine applying same

Abstract

The invention discloses a running deviation correcting device. The running deviation correcting device comprises an executing mechanism (1), a signal conversion component (2) and a controller (3), wherein the executing mechanism (1) comprises an executing component (11) and a horizontal pin shaft (12), which are hinged, a corner of the executing component (11) relative to the horizontal pin shaft (12) corresponds to a deviation angle of a vehicle wheel (02) of a rail-type engineering machine relative to a rail (01); the signal conversion component (2) is used for converting a corner signal of the executing component (11) relative to the horizontal pin shaft (12) into an electric signal; and the controller (3) is used for receiving the electric signal, calculating a deviation result of the vehicle wheel (02) relative to the rail (01) and regulating a speed of the vehicle wheel (02) such that a running direction of a whole vehicle trends to be parallel with the direction of the rail (01). The running deviation correcting device disclosed by the invention has a simple structure and can be used for controlling the running direction of the vehicle wheel in real time. The invention further discloses a rail-type engineering machine including the running deviation correcting device.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a walking deviation correction device for rail-type engineering machinery. In addition, the present invention also relates to a rail-type engineering machine comprising the above-mentioned walking deviation correcting device. Background technique [0002] Rail crane is a kind of loading and unloading machinery used for cargo loading and unloading and stacking operations in wharf or freight yard. The driving mechanism of the whole vehicle is an important part of the crane, which is used to make the crane walk along the track smoothly. [0003] When the rail crane walks along the track, it is difficult for the driving mechanism on both sides of the gantry to ensure that the running speed of each wheel is exactly the same, which leads to a certain angle between the overall walking direction of the vehicle and the track, and then causes the inside of the wheel rim to be...

Problems solved by technology

[0005] However, since the proximity switch in the deviation correction device of the above-mentioned rail crane has a threshold for distance detection, that is, the proximity switch can only output a closing signal when the wheels of the whole vehicle deviate to a certain extent, so the real-time detection of this deviation correction device The detection is not strong; and because the output signal is only a switch value, the deviation correction device needs to convert it into an analog output first, and then the offset of the rail crane can be calculated and analyzed by the controller. Therefore, this walking deviation correction device The control process is more complex
