Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

A mobile polymorphic ventilation facility, as shown in figures 1-5, comprising: a plurality of groups of lifting upright columns 2 are uniformly arranged side by side; an upper cross beam 4 and a lower cross beam 5 are respectively and fixedly arranged between the upper end and the lower end of the adjacent lifting upright columns 2. Wherein, the lifting upright post 2 is of a double-layer structure, as shown in figure 2, the outer layer and the inner layer are both sleeved square tubes 7; the lower end of the inner square tube 7 and the bottom of the inner tube of the outer square tube 7 are supported by a hydraulic jack 8, and the height of the inner square tube 7 is adjusted by operating a hydraulic handle up and down.

Further comprising: two groups of auxiliary frames symmetrically arranged on the two groups of lifting upright posts 2 on the outer side; each group of auxiliary frames comprises: the middle part of the side beam is fixedly connected with the outer ends of the lower cross beams 5 at two sides; two ends of the C-shaped frame 1 are rotatably connected with the tops of the side beams through rotating shafts and bearings; and the adjusting plates 9 are respectively detachably fixed between the two adjacent groups of lifting upright posts 2 and on the C-shaped frame 1.

As shown in fig. 1 and 3, the lifting columns 2 have three groups, and are respectively fixedly connected with the upper cross beam 4 and the lower cross beam 5 through bolts. A connecting baffle is detachably fixed between the adjacent adjusting plates 9, so that air leakage can be effectively reduced.

The upper cross beam 4 and the lower cross beam 5 are provided with clamping grooves, and the upper edge and the lower edge of the adjusting plate 9 are provided with convex blocks matched with the clamping grooves; the adjusting plate 9 is fixedly connected with the lifting upright post 2 through bolts, and the arrangement mode is convenient to detach and adjust.
