Here, the above description can be understood by those skilled in the art in conjunction with the erection process of the two channel steels 5, which is specifically as follows;

when the two lying channel steels 5 are placed on the support frame 21 in a lying posture, the support frame 21 is higher than the uppermost end of the turning-over component 23, namely, the two channel steels 5 are not subjected to standing and turning-over; in the process of controlling the movable element 25 and making the support frame 21 and the bottom frame 22 move relatively, the turnover component 23 gradually rises and penetrates through the gap on the support frame 21, for example, the roller 24 arranged on the support frame 21, and a roller gap 241 for the turnover component 23 to freely pass through is formed between two adjacent rollers 24; when the supporting frame 21 and the bottom frame 22 approach and move relatively, the turning-over component 23 gradually penetrates through the roller gap 241, and the following position relation relative to the channel steel 5 exists; firstly, when the first slope 2314 and the second slope 2316 just penetrate through the roller gap 241, the inclined surfaces of the first slope 2314 and the second slope 2316 are respectively attached to and contacted with the two channel steels 5, and in the process that the turnover assembly 23 continuously rises, because the first slope 2314 and the second slope 2316 have preset inclination angles and the channel steels 5 have self weights, under the action of gravity, the two channel steels 5 respectively slide to the first accommodating space 2317 and the second accommodating space 2318 along the inclination directions of the slopes, in the present case, the first accommodating space 2317 and the second accommodating space 2318 can be understood as being used for finally finishing standing of the channel steels 5, in order to ensure that the channel steels 5 can stably stand in the first accommodating space 2317 and the second accommodating space 2318, in the present embodiment, the transverse widths of the first accommodating space 2317 and the second accommodating space 2318 are the same, and the widths are matched with the widths of the channel steels 5 after standing, that is, the transverse width of the baffle 2312 and the inner side surface of the support portion is limited, so that the channel steel 5 is guaranteed not to shake left and right after standing. Meanwhile, it should be noted that, in this embodiment, the maximum displacement of the turning-over component 23 passing through the roller gap 241 is limited to the position where the upper end surface of the base portion 2311 is located below the upper end surface of the support frame, and here, it can be understood by those skilled in the art that, in order to realize that the channel steel 5 can roll on the roller 24 and transfer a station after turning-over and standing, that is, the bottom of the space where the maximum displacement of the turning-over component 23 is an accommodation space is just located on the roller surface of the roller 24, and meanwhile, the lower end surface of the channel steel 5 standing is only in surface contact with the roller 24, so that the channel steel 5 can move on the roller 24 after standing. For this reason, in order to further guarantee the removal flow degree of channel-section steel 5 on roller 24, in this embodiment, the equal smooth surface of medial surface of preferred baffle 2312 medial surface and supporting part sets up, and this kind of setting can guarantee that channel-section steel 5 when being located the accommodation space translation, the smooth frictional force that reduces its and baffle 2312 and supporting part medial surface that sets up in accessible surface to reach the more smooth and easy effect of this channel-section steel 5 removal. Here, it is also conceivable that a roller surface or a ball surface may be provided on both the inner surface of the stopper 2312 and the inner surface of the support portion in order to reduce the frictional force between the channel 5 and the stopper 2312 and the inner surface of the support portion during the movement, and the frictional resistance of the channel 5 during the movement may be further reduced by this arrangement.

In the embodiment, the surface of the slope is smooth, that is, in the present case, the surfaces of the slope surface one 2314 and the slope surface two 2316 are smooth, and when the slope surface one 2314 and the slope surface two 2316 contact the channel steel 5, the back surface of the channel steel 5 contacts the slope surface one 2314 and the slope surface two 2316 and respectively slides to the first accommodating space 2317 and the second accommodating space 2318 along the inclined surface, where those skilled in the art can understand that the slope surface one 2314 and the slope surface two 2316 have two functions, one of which is that, through a preset inclination angle, the channel steel 5 has a self-gravity effect in a lifting process in cooperation with the turnover assembly 23, and a guiding effect is achieved on the movement of the channel steel 5; secondly, through the smooth surface arrangement, the stable effect of the channel steel 5 in the moving process is achieved, and the channel steel falls into the first accommodating space 2317 and the second accommodating space 2318 smoothly and stably.

In addition, in the present embodiment, the inclination angle of the slope is 30 ° to 75 °, and here, the skilled person will understand without objection that the range of values includes any number of angular values, i.e. 30 ° or 31 ° or 32 ° or … … 75 °; it should be understood that, by limiting the inclination angle of the slope, the channel steel 5 can be ensured to smoothly slide into the first accommodating space 2317 and the second accommodating space 2318 through the self gravity in the process of turning over and erecting; when inclination is big more, it is steady more in its landing to the accommodation space, here, both can understand that, when inclination is big more, opening deviation of domatic upper shed department with the accommodation space is little for channel-section steel 5 is smooth-going more when falling into the accommodation space in-process, the effectual result of use that improves this kind of lift platform truck.
