The utility model provides an avoidance-free solid parking space which solves the problems of heavy weight and high cost. The avoidance-free solid parking space is characterized in that a revolving pillar is a four-truss type revolving pillar, wherein four supporting pillars of the revolving pillar are round pipes. The two adjacent supporting pillars serve as operation rails of a lifting sliding sleeve. When the loads are equal, the weight of the four-truss type revolving pillar is less than that of a square-pipe type revolving pillar and cost is lower. The lifting sliding sleeve in a box iron shape covers the operation rail. All idler wheels on the lifting sliding sleeve walk on the rail and each idler wheel is a saddle-type idler wheel. All the idler wheels are divided into three sets including a walking idler wheel set, a positioning idler wheel set and a swinging idler wheel set. A pair of positioning idler wheels is symmetrically installed on the inner sides of two groove walls of box iron to form the positioning idler wheel set. The swinging idler wheel set is composed of a pair of swinging idler wheel devices. The avoidance-free solid parking space has the advantages that the weight of equipment is greatly reduced, cost is greatly reduced and stability of the lifting sliding sleeve in the lifting process is greatly improved.
