Abstract
Description
Technical Field
[0001] This utility model belongs to the field of handling rack technology, specifically relating to a multi-layer stacking handling rack for construction materials. Background Technology
[0002] Multi-layer stacking and handling racks for construction materials are transportation tools designed for construction sites. They feature a multi-layered structure for the centralized storage and efficient transport of various building materials. The main body of the rack is typically constructed of a high-strength metal frame, with each layer connected by corner posts or longitudinal tubing to form a stable load-bearing structure. Casters or drive mechanisms are installed at the bottom of the frame for flexible movement. Multi-layer stacking and handling racks for construction materials not only improve transportation efficiency, increasing the capacity of a single transport several times over, reducing the number of round trips, and significantly shortening the construction period, but also optimize space utilization and save aisle space. These racks are widely used in construction sites, logistics warehousing, and industrial manufacturing.
[0003] Chinese Patent Publication No. CN219565159U discloses a construction material handling device, including a handling vehicle with a placement space for placing construction boards. The handling vehicle is equipped with several clamping components that clamp and limit the bottom of the construction boards, arranged at intervals. The handling vehicle also has several pressing components that press and limit the top of the construction boards. These pressing components cooperate with the clamping components to fix the position of the construction boards. This construction material handling device utilizes the pressing components to clamp and limit the top corners of the construction boards. Through the cooperation of the pressing and clamping components, each construction board placed on the handling vehicle is clamped and fixed, effectively solving the problem of difficult separation operations and easy damage to the construction boards caused by stacking them layer by layer.
[0004] In practical use, this utility model typically achieves material classification and storage through a layered design. However, the existing multi-layer stacking and handling racks for construction materials have fixed layer heights and lack flexible adjustment mechanisms. Workers find it difficult to conveniently place construction materials on higher shelves, especially when handling heavy or large materials, which requires multiple people to work together, leading to increased time and labor costs. This structural rigidity directly weakens the ease of operation of the handling rack and makes it difficult to meet the core needs of construction sites for efficient and flexible material transfer. Utility Model Content
[0005] This utility model proposes a multi-layer stacking and handling rack for construction materials to solve the problem of the difficulty in conveniently placing construction materials in different compartments of the handling rack in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer stacking and handling rack for construction materials, comprising:
[0007] The load-bearing plate and two support plates;
[0008] The mounting shaft is rotatably connected between two support plates. The two support plates are respectively arranged on both sides of the upper end of the bearing plate. Multiple mounting plates are provided on both sides of the mounting shaft. A common placement plate is provided between two mounting plates on the same side.
[0009] Multiple positioning shafts are rotatably connected to both ends of multiple placement plates. The ends of the multiple positioning shafts pass through the multiple mounting plates and extend to the outside. Multiple counterweights are provided at the bottom of the multiple placement plates.
[0010] A rectangular groove is formed inside the support plate, and a first screw is rotatably connected inside the rectangular groove. The external threads on both sides of the first screw are arranged in opposite directions.
[0011] To facilitate the positioning of multiple placement plates, the upper sides of the bearing plate are further provided with fixing rings. The two fixing rings are located on one side of multiple positioning shafts, and the bottom ends of the two fixing rings are provided with sliding plates. The bottom ends of the two sliding plates extend to both sides of the rectangular groove and are respectively provided with threaded holes adapted to the first screw. The first screw passes through the two threaded holes and is threadedly connected to the side wall of the threaded holes.
[0012] In a preferred embodiment, a drive groove is provided on one side of the support plate, and a servo motor is provided in the drive groove. One end of the first screw extends into the drive groove and is disposed on the output end of the servo motor.
[0013] In a preferred embodiment, a locking rod is provided through the support plate located on one side, and a plurality of mounting plates located on one side are provided with locking holes adapted to the locking rod, with one end of the locking rod located in the locking hole on one side.
[0014] In a preferred embodiment, a limiting ring is provided at one end of the locking rod, and a limiting spring is sleeved on the outside of the locking rod. The limiting spring is respectively provided on one side of the support plate and the limiting ring.
[0015] In a preferred embodiment, clamping plates are provided on both sides of the upper end of the plurality of placement plates, and multiple guide plates are provided at the bottom end of the plurality of clamping plates. Multiple guide grooves adapted to the guide plates are opened on both sides of the upper end of the plurality of placement plates. The plurality of guide plates are respectively located in the plurality of guide grooves and are each provided with a compression spring. The other end of the plurality of compression springs is respectively provided on one side of the plurality of guide grooves.
[0016] In a preferred embodiment, each of the multiple placement plates is provided with a limiting plate at its bottom end, baffles are provided on both sides of the upper end of each of the multiple placement plates, and protective frames are provided on both sides of the upper end of each of the multiple limiting plates. The multiple protective frames pass through the multiple placement plates and extend to the outside.
[0017] To facilitate the handling or placement of construction materials, the bottom ends of the multiple placement plates are rotatably connected to second screws, and the multiple limiting plates are provided with threaded grooves that are adapted to the second screws. The multiple second screws pass through the multiple threaded grooves and are threadedly connected to the threaded grooves.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. This utility model, through multiple mounting plates set on both sides of the mounting shaft, and in conjunction with multiple rotatable positioning shafts, can drive the mounting plates to synchronously adjust the placement plates by rotating the mounting shaft, thereby realizing the adjustment of the height and position of each layer of placement plates. This allows construction materials to be conveniently placed in different compartments of the multi-layer stacking and handling rack, or to be taken out from the multi-layer stacking and handling, saving time and manpower for the handling of construction materials, and making the multi-layer stacking and handling rack for construction materials more convenient to use;
[0020] 2. This utility model, through the installation of liftable protective frames on both sides of multiple placement plates, significantly improves operational safety and flexibility. When workers load and unload materials, the protective frames can be lowered to be flush with the placement plates, eliminating the obstruction of the transport path by traditional fixed fences. This allows construction materials to be directly pushed into or moved out of the shelf. During transportation, the protective frames can form a rigid barrier, effectively preventing construction materials from slipping due to bumps. This significantly improves the practicality and efficiency of multi-layer transport racks in complex construction scenarios. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example 1:
[0030] Please see Figure 1-6 This utility model provides a multi-layer stacking and handling rack for construction materials, comprising:
[0031] Load-bearing plate 1 and two support plates 2;
[0032] The mounting shaft 3 is rotatably connected between two support plates 2. The two support plates 2 are respectively set on both sides of the upper end of the bearing plate 1. Multiple mounting plates 4 are provided on both sides of the mounting shaft 3. The same placement plate 5 is provided between two mounting plates 4 on the same side.
[0033] Multiple positioning shafts 6 are respectively set at both ends of multiple placement plates 5. The ends of the multiple positioning shafts 6 pass through multiple mounting plates 4 and extend to the outside. Multiple counterweights 7 are provided at the bottom of the multiple placement plates 5.
[0034] A rectangular groove is formed inside the bearing plate 1, and a first screw 8 is rotatably connected inside the rectangular groove. The external threads on both sides of the first screw 8 are arranged in opposite directions.
[0035] Specifically, such as Figure 1 and Figure 2 As shown, the upper end of the bearing plate 1 is provided with two fixing rings 9 on both sides. The two fixing rings 9 are located on one side of the multiple positioning shafts 6 respectively. The bottom end of the two fixing rings 9 is provided with a sliding plate 22. The bottom end of the two sliding plates 22 extends to both sides of the rectangular groove and is provided with threaded holes that are compatible with the first screw 8. The first screw 8 passes through the two threaded holes and is threadedly connected to the side wall of the threaded hole.
[0036] By rotating the first screw 8, the sliding plates 22 and the fixing rings 9 on both sides can be moved in opposite directions. The two fixing rings 9 will abut against one end of the multiple positioning shafts 6 on both sides, thereby locking the angle and height of the multiple placement plates 5 and ensuring the stability of the handling of construction materials.
[0037] Specifically, such as Figure 2 As shown, a drive groove is provided on one side of the support plate 1, and a servo motor 10 is provided in the drive groove. The servo motor 10 is existing technology and will not be described in detail here. One end of the first screw 8 extends into the drive groove and is set on the output end of the servo motor 10. When the servo motor 10 is started, its output end will drive the first screw 8 to rotate.
[0038] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, a locking rod 11 is provided through the support plate 2 on one side, and a number of mounting plates 4 on one side are provided with locking holes 12 that are adapted to the locking rod 11. One end of the locking rod 11 is located in the locking hole 12 on one side. By installing the locking rod 11 into the corresponding locking hole 12, the angle of the mounting shaft 3 and the multiple mounting plates 4 can be limited, so as to prevent them from rotating or shifting during transportation or loading and unloading, thus ensuring the stability of the multi-layer stacking and handling rack for construction materials.
[0039] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a limiting ring 13 is provided at one end of the locking rod 11, and a limiting spring 14 is sleeved on the outside of the locking rod 11. The limiting spring 14 is respectively provided on one side of the support plate 2 and the limiting ring 13. The limiting ring 13 cooperates with the limiting spring 14 to ensure that the locking rod 11 is always located in the locking hole 12.
[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, multiple placement plates 5 are provided with clamping plates 15 on both sides of their upper ends, and multiple clamping plates 15 are provided with multiple guide plates 16 at their bottom ends. Multiple guide grooves adapted to the guide plates 16 are opened on both sides of the upper ends of multiple placement plates 5. The multiple guide plates 16 are located in the multiple guide grooves and are each provided with a compression spring 17. The other end of the multiple compression springs 17 is respectively set on one side of the multiple guide grooves. The multiple guide plates 16 can respectively restrict the movement of the multiple clamping plates 15, and the multiple compression springs 17 can respectively restrict the position of the multiple guide plates 16. In this way, the multiple clamping plates 15 can abut against the end of the construction material and limit its position, thus ensuring the stability of the multi-layer stacking and handling rack for handling construction materials.
[0041] Example 2:
[0042] Please see Figure 1-6 This utility model provides a multi-layer stacking and handling rack for construction materials, comprising:
[0043] Load-bearing plate 1 and two support plates 2;
[0044] The mounting shaft 3 is rotatably connected between two support plates 2. The two support plates 2 are respectively set on both sides of the upper end of the bearing plate 1. Multiple mounting plates 4 are provided on both sides of the mounting shaft 3. The same placement plate 5 is provided between two mounting plates 4 on the same side.
[0045] Multiple positioning shafts 6 are respectively set at both ends of multiple placement plates 5. The ends of the multiple positioning shafts 6 pass through multiple mounting plates 4 and extend to the outside. Multiple counterweights 7 are provided at the bottom of the multiple placement plates 5.
[0046] A rectangular groove is formed inside the bearing plate 1, and a first screw 8 is rotatably connected inside the rectangular groove. The external threads on both sides of the first screw 8 are arranged in opposite directions.
[0047] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, each of the multiple placement plates 5 has a limiting plate 18 at its bottom end, and each of the multiple placement plates 5 has a baffle 19 on both sides of its upper end. Each of the multiple limiting plates 18 has a protective frame 20 on both sides of its upper end. The multiple protective frames 20 pass through the multiple placement plates 5 and extend to the outside. The baffle 19 and protective frame 20 at the upper end of the placement plate 5 can prevent construction materials from slipping due to bumps during transportation.
[0048] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the bottom ends of multiple placement plates 5 are rotatably connected to second screws 21, and multiple limiting plates 18 are provided with threaded grooves that are adapted to the second screws 21. The multiple second screws 21 pass through multiple threaded grooves respectively and are threadedly connected to the threaded grooves.
[0049] By rotating the second screw 21, the limiting plate 18 can be moved up and down. The limiting plate 18 will move the upper protective frame 20 up and down. This not only makes it convenient to place or take out construction materials, but also protects the construction materials and prevents them from falling during transportation.
[0050] See Figure 1-6When using a multi-layer stacking transport rack to handle construction materials, firstly, multiple second screws 21 need to be rotated. The second screws 21 will drive multiple limit plates 18 and multiple protective frames 20 to move downwards respectively. Then, by rotating the mounting shaft 3, multiple mounting plates 4 are driven to rotate. The multiple mounting plates 4 will drive multiple positioning shafts 6 and multiple placement plates 5 to rotate respectively, thereby adjusting the height and position of the multiple placement plates 5. Construction materials can be conveniently placed on the multiple placement plates 5. During placement or transportation, by placing the locking rods 11 into the locking holes 12 on the multiple mounting plates 4 respectively, the positions of the multiple mounting plates 4 and multiple placement plates 5 can be stably locked, ensuring their stability during transportation or loading and unloading. When the construction materials are placed, the servo motor 10 is started. The output end of the servo motor 10 will drive the first screw 8 to rotate. The first screw 8 will drive the sliding plates 22 on both sides and the fixing ring 9 to move in opposite directions, which can limit the position of the positioning shafts 6, thereby limiting the angle and position of the multiple placement plates 5, ensuring the stability of the multi-layer stacking transport rack in handling construction materials.
[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
