Abstract

The utility model discloses a spring hydraulic internal supporting type parking anti-running device which comprises an executing mechanism, the executing mechanism is connected with an integrated block assembly through an executing pipe, the integrated block assembly is connected with an oil pump assembly through a first connecting pipe, the integrated block assembly is connected with an oil tank, the oil tank is connected with the oil pump assembly, and the oil tank is further connected with an energy accumulator. The energy accumulator is connected with the integrated block assembly through a second connecting pipe; during braking, hydraulic oil in the oil cylinder returns to the oil tank through the overflow valve, so that the braking capacity of the parking anti-slip device is convenient to adjust, the applicability of equipment is expanded, anti-slip is reliably carried out on a vehicle, and the safety of operation of a hump shunting yard is improved. When a vehicle is relieved, the spring and the working spring are installed in the oil cylinder, the oil cylinder is of a single-action type, hydraulic oil in the oil cylinder returns to an oil tank through the reversing valve during relieving, and the oil cylinder is novel in design, compact and simple in structure and safe and reliable in work.
