Remote control locomotive car lifting jack system and control method

Abstract

The invention is suitable for the field of car lifting jacks, and provides a remote control locomotive car lifting jack system and a control method.The remote control locomotive car lifting jack system comprises at least four machine frames and a control system, and the control system lifts a maintenance locomotive by controlling the machine frames; the control system comprises a programmable logic controller (PLC), a touch screen human machine interface (HMI), a driving unit, a rack feedback unit, a remote controller unit and other switching devices. Protection of all the racks in the synchronous mode is interconnected, operation cannot be carried out as long as one fault occurs, and all the racks cannot move in the direction as long as one fault reaches the limit; meanwhile, the PLC automatically detects the position increment of each rack, the rack moving quickly waits for the rack moving slowly automatically, and it is guaranteed that the maximum increment error of each rack does not exceed 10 mm; each rack, the remote controller unit and the touch screen HMI are provided with scram buttons, so that the action of the rack can be quickly stopped through any one of the scram buttons in emergency; and the remote controller unit is adopted, so that an operator can realize wireless remote control in a relatively large range, and observation is facilitated.

Description

technical field [0001] The invention belongs to the field of locomotive cranes, and in particular relates to a remote-controlled locomotive crane system and a control method. Background technique [0002] Both vehicle manufacturing and maintenance require the use of cranes. The main function of the crane is to lift the vehicle, which is beneficial for the staff to work under the vehicle, and to facilitate the staff to install, replace or repair the parts at the bottom of the vehicle. After the work under the vehicle is completed, the crane is also responsible for lowering the vehicle back to the ground. [0003] In actual operation, four racks are needed to lift the locomotive that needs to be repaired, so it is particularly important to ensure the synchronous operation of multiple racks. In the prior art, multiple racks cannot be accurately controlled, and there are potential safety hazards. Contents of the invention [0004] The purpose of the embodiments of the presen...
