The invention discloses a crawler bridge structure which comprises a crawler bridge body, a differential lock mechanism and a brake pump system, a differential mechanism, a first half shaft and a second half shaft are arranged in the crawler bridge body, the brake pump system comprises a hydraulic cylinder, a brake pump and a brake pipe, and the brake pump system is arranged outside the crawler bridge body. The differential mechanism comprises a differential mechanism shell, a universal joint pin, planetary gears, a first half axle gear, a second half axle gear and a jaw assembly, the universal joint pin is movably connected with the differential mechanism shell through the planetary gears, and the first half axle gear and the second half axle gear are connected with the corresponding planetary gears in a meshed mode. The first half shaft and the second half shaft are detachably connected with the first half shaft gear and the second half shaft gear correspondingly, the differential lock mechanism is arranged on the side, close to the brake pump system, of the crawler bridge body, and the differential lock mechanism is movably connected with the jaw assembly and the hydraulic cylinder. The device is simple in structure, small in occupied space and convenient to maintain, the use cost is greatly reduced, and the device has high popularization value.
