Gantry crane tire automatic inflation and deflation system

The invention discloses an automatic inflation and deflation system for a gantry crane tire, which is mounted on a gantry crane and comprises an inflation pump mounted on the gantry crane; the first electromagnetic valve is communicated with the inflator pump; the first multi-way pipe is communicated with the first electromagnetic valve; the air pressure sensor is mounted between the multi-way pipe and the first electromagnetic valve; the plurality of air tap joints are communicated with the first multi-way pipe fitting, and the air tap joints are mounted on an inflation nozzle of a tire; and the controller is electrically connected with the inflator pump, the first electromagnetic valve and the air pressure sensor. According to the device, the tires on the two sides of the gantry crane are always kept consistent in tire pressure, the tedious degree of detection is reduced, automatic inflation and deflation of all the tires can be carried out at a time, and labor saving and convenience of inflation and deflat
