Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a material stacking support device for construction sites, comprising a frame 1, which is an integrated material rack. A fixing plate 2 5 is fixedly connected to the middle of the frame 1 to increase the stability of the connection. Rollers are fixedly installed at the bottom of the frame 1 to facilitate its movement. An expansion component for increasing material stacking space is provided at the top of the frame 1. The expansion component includes lifting rods 2 that can be raised by four sets of lifting rods 2 to increase the stacking space. The lifting rods 2 are slidably connected to the top right side of the frame 1. A connecting rod 21 is fixedly connected to the left side of the lifting rods 2. Two sets of connecting rods 21 are fixedly connected between every two sets of lifting rods 2 to increase the stability of the two sets of lifting rods 2. The connecting rod 21 is slidably connected to the inner wall of the left side of the right side of the frame 1. A support ring 22 for driving the connecting rod 21 to rise and fall is fixedly connected to the outer wall of the right end of the connecting rod 21 near the inner wall of the left side of the right side of the frame 1.

[0031] Furthermore, the bottom end of the support ring 22 is hinged to a connecting block 23 that drives the support ring 22 to rise and fall. The connecting block 23 is set in an inclined shape, so that after the guide ring 28 pushes the left end of the inclined connecting block 23, the right end of the connecting block 23 moves upward and pushes the connecting rod 21 to move upward. The bottom end of the connecting block 23 is hinged to a guide ring 28 that drives the left end of the connecting block 23 to move and pushes the right end to rise and fall. The left side of the front bottom of the frame 1 is rotatably connected to a two-way threaded rod 27 that is threaded to the two sets of guide rings 28 and drives the two sets of guide rings 28 to move in opposite directions, thereby pushing the upper ends of the two sets of connecting blocks 23 to move upward. The left side of the two-way threaded rod 27, near the left side of the frame 1, is fixedly connected to a bevel gear 24 that drives the two-way threaded rod 27 to rotate. The middle left side of the frame 1 is fixedly connected to a fixed plate 4 that provides support.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The bottom end of the fixed plate 2 5 is provided with a support component, which includes a support plate 3 that increases the contact area with the ground to increase stability. The top front of the support plate 3 has a positioning groove 35 and two sets of positioning grooves. The positioning groove 35 provides space for the positioning block 32 to move. The top middle of the support plate 3 has a through groove 36 that provides space for the guide frame 33 to move.

[0033] Reference Figure 1 , Figure 2 and Figure 3A rotating rod 26, which drives two sets of bevel gears 25, is rotatably connected through the front and rear surfaces of the middle part of the fixed plate 4. A bevel gear 25 is fixedly connected to the outer wall of the rotating rod 26 near the left side of the bevel gear 24. Both the bevel gear 25 and the bevel gear 24 have two sets, respectively located on the front left and rear left sides of the frame 1. The two sets of bevel gears 25 can drive the two sets of bevel gears 24 to rotate simultaneously, thus simultaneously raising and lowering multiple lifting rods 2. A guide ring 28 is slidably connected to the top right side of the front inner wall of the frame 1, and the guide ring 28 is threaded. At the threaded part of the right outer wall of the bidirectional threaded rod 27, bevel gear 25 meshes with bevel gear 24. Bevel gear 25 can drive bevel gear 24 to rotate. The front and rear surfaces of the rotating rod 26 are fixedly connected to turntables that drive the rotating rod 26 to rotate. Multiple sets of bidirectional threaded rod 27, connecting block 23, connecting rod 21, and lifting rod 2 are provided. These multiple sets of bidirectional threaded rod 27, connecting block 23, connecting rod 21, and lifting rod 2 are symmetrically arranged at the rear of the frame 1 with the center line of the frame 1 as the axis of symmetry. By providing multiple sets, the stability of the lifting rod 2 in raising and lowering can be increased.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The bottom end of the second fixed plate 5 is fixedly connected to a positioning block 32 to increase the stability of the movement of the support plate 3. The positioning block 32 is slidably connected to the inner wall of the positioning groove 35. The left middle of the first fixed plate 4 is rotatably connected to a threaded rod 31 that is threadedly connected to the guide frame 33 and drives the guide frame 33 to move. The left side of the threaded rod 31 is also fixedly connected to a turntable to facilitate the rotation of the threaded rod 31. The bottom end of the second fixed plate 5 is slidably connected to a guide frame 33 that is set in an inclined position to drive the guide rod 34 to rise and fall. The bottom end of the second fixed plate 5 is close to the right side of the guide frame 33. A support block 37 is fixedly connected to the side of the threaded screw 31. The right end of the threaded screw 31 is rotatably connected to the left side of the support block 37. The top center of the guide frame 33 is threaded through and threaded to the outer wall thread of the threaded screw 31. The bottom of the guide frame 33 is set in an inclined shape. By setting it in an inclined shape, the guide rod 34 can be squeezed to make the guide rod 34 move upward or downward to drive the support plate 3. The inner wall center of the through groove 36 is fixedly connected to the guide rod 34, which drives the support plate 3 to rise or fall. The guide rod 34 is slidably connected to the inner wall of the guide frame 33.

[0035] Working principle: When it is necessary to expand the material storage space at the top of the frame 1, the rotating rod 26 can be rotated to drive the two sets of bevel gears 25 on its outer wall to rotate synchronously. Since the bevel gears 25 mesh with the bevel gears 24, the bevel gears 24 will rotate accordingly, thereby driving the bidirectional threaded rod 27 to rotate. The bidirectional threaded rod 27 is threadedly connected to two sets of guide rings 28, and its thread is bidirectional. During the rotation, the two sets of guide rings 28 will slide in opposite directions along the bidirectional threaded rod 27. The movement of the guide rings 28 will push the left end of the hinged and inclined connecting block 23, causing the right end of the connecting block 23 to move. The upward movement pushes the support ring 22 upward, causing the connecting rod 21 to rise and drive the lifting rod 2 to slide upward along the top right side of the frame 1. Since multiple sets of bidirectional threaded rods 27, connecting blocks 23, connecting rods 21, and lifting rods 2 are symmetrically arranged at the rear of the frame 1 with the center line of the frame 1 as the axis of symmetry, and two sets of connecting rods 21 are fixedly connected between every two sets of lifting rods 2, multiple sets of lifting rods 2 can rise synchronously and stably, forming a higher stacking space at the top of the frame 1 to place more materials, improving the capacity of the frame 1 to stack pipe materials, and further improving space utilization and flexibility.

[0036] In daily use, the rollers at the bottom of the frame 1 facilitate the movement of the entire device on the construction site, allowing it to be quickly placed in a suitable position for material stacking and retrieval. When it is necessary to enhance the stability of the frame 1, the turntable on the left side of the threaded screw 31 is rotated. The threaded screw 31 is threadedly connected to the top center of the guide frame 33, thereby causing the guide frame 33 to slide at the bottom of the fixed plate 2 5. The bottom of the guide frame 33 is inclined. During its movement, it will squeeze the guide rod 34 in the middle of the inner wall of the through groove 36. When the guide frame 33 moves in a specific direction, the guide rod 34 will move downward, thereby causing the connected support plate 3 to descend. After descending to contact the ground, it provides support, thereby increasing the contact area between the frame 1 and the ground, and thus improving the stability of the frame 1.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
