[0004] In the above scheme, although the wall panels can be made vertical, they need to be placed vertically and the bottom side edges of the wall panels need to be accurately placed in the square grooves. Although this is convenient for subsequent lifting, it increases the time required for placing the wall panels. In addition, the wall panels are positioned using a square groove structure with concave support blocks. At this time, the area of ​​the wall panels in the square grooves is limited and the wall panels are in an upright state. At this moment, the stability of the wall panels is poor. Once a wall panel flips over, other wall panels are easily affected and flipped over, affecting the quality of the wall panels. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 6As shown, a prefabricated wall panel stacking rack includes a bottom bracket 1, on which a backrest plate 2 is arranged, and the backrest plate 2 is vertically connected to the bottom bracket 1. A wall panel 3 can be placed on the bottom bracket 1. At this time, the wall panel 3 may be in an inclined state. To prevent the wall panel 3 from slipping, a protrusion or a groove can be arranged on the bottom bracket 1. The protrusion or the groove forms a locking structure. At this time, the bottom side of the wall panel 3 will cooperate with the locking structure, which forms a triangular stable structure with the bottom bracket 1 and the backrest plate 2. Since the two adjacent There is no gap between the top and side edges of the wall panels 3, so a slidable door frame 4 is also provided on the bottom bracket 1, and a wall panel correction component is provided on the door frame 4. The door frame 4 can be moved to the wall panel 3 that needs to be lifted, and then the wall panel can be adjusted from an inclined state to a nearly vertical state by controlling the operation of the wall panel correction component. At this time, there is a gap between the top and side edges of two adjacent wall panels 3, and the connecting piece can be conveniently inserted into the gap so that the connecting piece clamps the corresponding wall panel, and then the wall panel can be lifted.

[0025] The wall panel correction component includes a boom 5 arranged on the door frame 4. When the door frame 4 is in a vertical state, the boom 5 is located above the door frame 4. Both ends of the boom 5 are connected with vertical arms 6. A correction clamp 7 is fixed to the lower end of each vertical arm 6. A lifting component 8 is connected between the boom 5 and the door frame 4. The lifting component 8 is an electric push rod with a telescopic structure. When the lifting component 8 is extended or shortened, the boom 5 can be adjusted to move upward or downward, thereby changing the horizontal height of the boom 5. When the boom 5 moves vertically, the correction clamp 7 also moves vertically accordingly. However, since the correction clamp 7 is connected to the door frame 4, the movement of the correction clamp 7 is relatively stable at this time, forming a connection structure for controlling the vertical movement of the correction clamp 7 when the lifting component 8 is extended or shortened.

[0026] When the correction clamp 7 is connected to the wall panel 3, it does not clamp the wall panel 3. The specific structure is as follows: the correction clamp 7 includes a vertical slide 9 arranged on the door frame 4, and the vertical slide 9 is connected to the lower end of the vertical arm 6. After the horizontal height of the boom 5 changes, the vertical slide 9 also moves vertically. At the same time, a sliding clamp is arranged on the vertical slide 9. The door frame 4 is located between the backrest plate 2 and the sliding clamp. The sliding clamp includes a horizontally extending support arm 10, and the support arm 10 is connected to a front stop rod 11 and a rear support rod 12. Rod 12, the front gear rod 11 and the rear gear rod 12 are all in a horizontal state, and at this time the front gear rod 11 and the rear gear rod 12 are both perpendicular to the support arm 10, and the lower part of the wall panel 3 can enter between the front gear rod 11 and the rear support rod 12. At this time, when the sliding clamp moves upward, it will apply a thrust to the wall panel, but because the bottom side of the wall panel 3 is stuck in the locking structure, the wall panel 3 is controlled to flip to a vertical state through the sliding clamp. When the wall panel 3 starts to flip, there is a gap between the upper ends of two adjacent wall panels 3.

[0027] The rear support rod 12 includes a bottom rod 121 and a flip rod 122. The bottom rod 121 is fixed on the support arm 10. The bottom rod 121 is parallel to the front gear rod 11. The flip rod 122 is hinged at the free end of the bottom rod 121. Specifically, a hinge plate 123 is provided near the rear end of the flip rod 122. At the same time, a notch is provided at the front end of the bottom rod 121. The hinge plate 123 is located in the notch. A short shaft 124 is fixed at the center of the hinge plate 123. The short shaft 124 is connected to the front end of the bottom rod 121. , so that the flip rod 122 can flip toward the front gear rod 11, and the maximum angle formed between the flip rod 122 and the front gear rod 11 is 180°. At this time, the flip rod 122 is parallel to the front gear rod 11 and the two are in contact, that is, when the flip rod 122 is parallel to and in contact with the bottom rod 121, the flip rod 122 can only flip toward the front gear rod 11, but cannot flip in the direction away from the front gear rod 1. In this way, when the sliding clamp moves upward, a thrust can be applied to the wall panel through the rear support rod 12.

[0028] During the movement of the sliding clamp, since the flip rod 122 first contacts the wall panel 3, the wall panel 3 cannot move at this time, so the flip rod 122 flips toward the front stop rod 11. When it flips and moves to a point where it no longer forms a mutual obstruction with the wall panel, the flip rod 122 needs to be reset before the wall panel can be located between the rear support rod 12 and the front stop rod 11. Therefore, a waist-shaped opening is provided on the bottom rod 121, and the waist-shaped opening extends along the length direction of the bottom rod 121. A tension reset spring 13 passes through the waist-shaped opening, and the two ends of the tension reset spring 13 are respectively connected to the front stop rod 11. It is connected to the flip rod 122. When the flip rod 122 flips toward the front gear rod 11, the rear end of the flip rod 122 moves away from the front gear rod 11. At this time, the rear end of the flip rod 122 is separated from the bottom rod 121, and a pulling force is applied to the stretching reset spring 13, so that the stretching reset spring 13 changes from a normal state to a stretched state. When the wall panel 3 and the flip rod 122 no longer form mutual obstruction, the stretching reset spring 13 flips and resets the flip rod 122 under the action of its own restoring force. At this time, the wall panel 3 is located in the area between the flip rod 122 and the front gear rod 11.

[0029] In addition, when controlling the vertical slide 9 to move vertically, in order to maintain the stability of the movement, two positioning sleeves 14 are fixed on the door frame 4, and the vertical arm 6 passes through the positioning sleeves 14 on the corresponding side. The door frame 4 includes a crossbeam 15 and a door post 16. There are two door posts 16, and the upper ends of the two door posts 16 are respectively connected to the two ends of the crossbeam 15. The two positioning sleeves 14 are respectively fixed on the two door posts 16, and the central axis of the positioning sleeves 14 is parallel to the door post 16. The lifting component is fixed at the middle position of the crossbeam 15, and a displacement seat 17 is connected to the foot end of the door frame 4 (that is, the lower end of the door post). The displacement seat 17 is connected to the bottom bracket 1. When the displacement seat 17 moves in the horizontal direction, the displacement seat 17 can drive the door frame 4 to move horizontally. At this time, the wall panel correction assembly also moves accordingly. Finally, the bottom rod on the wall panel correction assembly contacts the wall panel, causing the flip rod to flip, and finally the wall panel is located between the flip rod and the front gear rod.

[0030] The above-mentioned displacement seat 17 includes a bottom base 171 and a locking plate 172. The locking plate 172 is hinged to the side of the bottom base 171. The locking plate 172 is fixedly connected to the foot end of the door frame 4. At the same time, a guide rail 18 is arranged on the bottom bracket 1. The cross-section of the guide rail 18 is "T"-shaped, and a rail groove is arranged on the lower surface of the bottom base 171. The guide rail 18 fits in the rail groove so that the bottom base 171 can move along the length direction of the guide rail 18. A horizontally extending pipe through-hole is also arranged on the bottom base 171, and a screw assembly passes through the through-hole. A drive motor 19 is fixed on the bottom bracket 1. The output shaft of the drive motor 19 is connected to the screw 20 on the screw assembly. The drive motor 19 can control the bottom base 171 to slide along the length direction of the guide rail 18 through the screw assembly, thereby driving the door frame 4 and the wall panel straightening assembly to move horizontally.
