Loading machine auxiliary parking device with load as power source

The utility model provides a loading machine auxiliary parking device with load as a power source. The loading machine auxiliary parking device comprises a vehicle frame working machine body, a hydraulic cylinder and a parking brake. A brake caliper braking piston is configured on the parking brake, the front portion of the vehicle frame working machine body is provided with a material loading hopper, the hydraulic cylinder is supported on the material loading hopper, an oil pipe is connected between the hydraulic cylinder and the brake caliper braking piston, and a magnetic valve is installed on the oil pipe. When a loading machine is loaded, the brake caliper braking piston is pushed through pressure of the hydraulic cylinder to enable a transmission shaft to stop transmitting and achieve the braking effect. The loading machine auxiliary parking device has the advantages that safe, reliable, quick and balanced parking and braking are achieved when load of the loading machine is large.
