The utility model relates to a kind of modularization superposition type heavy vehicle wheel auxiliary support moving mechanism of road clearing equipment technical field, including supporting wheel frame, wheel shaft and gyro wheel group, supporting wheel frame includes a group of side support, several parallel support connecting rods are fixed between two side supports, the arc-shaped support portion capable of supporting heavy vehicle wheel is formed between each support connecting rod, and it further includes at least one modularization cushion block capable of being placed on arc-shaped support portion.The utility model is matched with modularization cushion block by the supporting wheel frame of split design, can sequentially stack modularization cushion block on supporting wheel frame, so as to match the wheel of different vehicle models and its various accident states (including flat tire, no tire, no tire and no steel ring, no hub etc.), wheel can be raised according to the actual situation of wheel and its various accident states, so that each wheel of accident vehicle is at the same height, while avoiding the relative motion of wheel and supporting wheel frame, thereby greatly improving the safety, rapidity and effectiveness when wrecker clears obstacles.

The utility model discloses an oxygen valve station device which comprises a main oxygen pipe, and the main oxygen pipe distributes oxygen to a first oxygen branch pipe and a second oxygen branch pipe through a valve set. And the valve group connected with the oxygen main pipe comprises a third oil-forbidding stop valve, an oxygen pressure gauge, a second oil-forbidding ball valve, a filter, an oxygen check valve, an oxygen flow meter and a pressure transmitter which are connected in sequence. According to the oxygen valve station device, modularization and integrated assembly are adopted, the oxygen valve station device adapts to the rapid installation characteristic of an on-site engineering project, the oxygen valve station device can be assembled in a factory area, the situation that the on-site dust environment pollutes an oxygen pipeline is avoided, and the use safety of the valve station is improved.
