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.

The utility model discloses a detachable and reusable casing hanger, and belongs to the technical field of oil and gas drilling and production equipment. The hanger aims at solving the problem that an existing hanger cannot be disassembled without damage and reused. The C-shaped casing hanger body is made of an elastic metal material and provided with a notch, and the annular retention sleeve is arranged above the C-shaped casing hanger body. During installation, the retention sleeve is rotated to apply axial pressure to the hanger body, so that the hanger body moves downwards along the inclined surface of the inner wall of the casing head and is tightened in the radial direction, and a casing is clamped; and during disassembly, the retention sleeve is reversely rotated to relieve the pressure, and the hanger body is automatically bounced off and loosened by virtue of self elasticity. The device is simple in structure and convenient to mount and dismount, can realize complete lossless dismounting and reutilization, and remarkably reduces the operation cost and the material consumption.
