The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.
[0020] The current prefabricated staircase stacking rack does not have a buffer protection structure when in use. Since the staircase itself is heavy, the impact force generated when placing the staircase will also be large. When the staircase is placed directly on the stacking rack, it may be damaged due to the strong impact force, which brings inconvenience to the staff;
[0021] In view of this, the utility model provides a prefabricated staircase stacking rack for construction sites, which can automatically perform buffering protection through the cooperation of the buffer device, thereby avoiding the phenomenon that when the prefabricated stairs are placed, the stairs are subjected to a large impact force and are damaged due to their own high weight, thereby ensuring the subsequent quality of use and facilitating subsequent use by the staff.

[0024] Specifically, when using the prefabricated stair stacking rack on the construction site, when the stairs need to be placed, the staff turns on the external power supply of the removing device 4. When the removing device 4 moves to a certain position, the prefabricated stairs can be placed on the top of the removing device 4. At this time, the buffer device 3 can perform a buffering and protective role. Then the staff turns on the external power supply of the adjusting device 2. At this time, the adjusting device 2 can change the overall spatial layout of the prefabricated stair stacking rack on the construction site, and then the prefabricated stairs can be placed again.
[0025] Embodiment 2: By Figure 1 , 2As can be seen from 3, the adjustment device 2 includes: a first hydraulic cylinder 201, the model of the first hydraulic cylinder 201 is not specifically limited, and it can meet the use requirements. A plurality of them are set and installed above the two sides of the base plate 1 respectively; two first brackets 204 are set and installed on the top of the base plate 1 respectively; a plurality of second brackets 203 are set and installed above the two first brackets 204 respectively; a plurality of support plates 202 are set and installed on the outer walls of the plurality of second brackets 203 respectively, and the plurality of support plates 202 located below are detachably connected to the output ends of the plurality of first hydraulic cylinders 201 located below, the tops of the plurality of support plates 202 located below are detachably connected to the bottoms of the plurality of first hydraulic cylinders 201 located above, and the bottoms of the plurality of support plates 202 located above are detachably connected to the output ends of the first hydraulic cylinders 201 located above; wherein the first hydraulic cylinder 201 can change the positions of the support plates 202 and other components through the support plates 202, thereby changing the height of the prefabricated stairs;
[0026] In the specific implementation process, it is worth pointing out that the first hydraulic cylinder 201 can change the position between the first bracket 204 and the second bracket 203, thereby changing the overall layout of the prefabricated staircase stacking rack at the construction site, so that the picking and placing work can be carried out more conveniently;
[0027] Specifically, based on the above-mentioned embodiment 1, when it is necessary to change the overall height layout of the prefabricated staircase stacking rack on the construction site, the staff turns on the external power supply of the first hydraulic cylinder 201. At this time, the first hydraulic cylinder 201 can change the position between the first bracket 204 and the second bracket 203 through the support plate 202, thereby changing the overall spatial layout of the prefabricated staircase stacking rack on the construction site, so that the prefabricated stairs can be taken and placed more conveniently.

[0032] In the specific implementation process, it is worth pointing out that the slide bar 402 can limit the position between the moving plate 404 and the horizontal plate 401, and the second hydraulic cylinder 403 can change the position between the moving plate 404 and the horizontal plate 401, so that the staff can more conveniently carry out the work of taking the prefabricated stairs;
[0033] Furthermore, a plurality of balls 5 are installed on the top of the plurality of horizontal plates 401, and the outer walls of the plurality of balls 5 are movably connected to the bottom grooves of the plurality of moving plates 404 respectively;
[0034] In the specific implementation process, it is worth pointing out that the ball 5 can reduce the friction between the moving plate 404 and the horizontal plate 401, thereby reducing the wear rate between the moving plate 404 and the horizontal plate 401;
[0035] Specifically, based on the above-mentioned embodiments one and two, when it is necessary to take the prefabricated stairs, the staff turns on the external power supply of the second hydraulic cylinder 403. At this time, the second hydraulic cylinder 403 can drive the moving plate 404 to slide along the top of the outer wall of the horizontal plate 401. At the same time, the slide bar 402 follows the moving plate 404 to slide along the inner wall of the horizontal plate 401. When the moving plate 404 moves to the appropriate position, the stairs can be taken.
