Description

Technical Field

[0001] This invention relates to the technical field of material stacking devices at construction sites, and specifically to a material stacking and turnover device for construction. Background Technology

[0002] Construction site reusable materials are indispensable "current assets" in construction projects. They are not disposable items but are repeatedly used during construction, providing strong support for project progress. Common reusable materials include formwork, scaffolding, and safety nets. Currently, when construction site reusable materials are not in use, they are often simply piled on the ground or stacked using timber support structures. However, this method has significant drawbacks in transportation: when using forklifts to move stacked reusable materials, the forklift forks are difficult to accurately insert into the bottom or gaps in the timber supports, making it impossible to lift the materials in one go. Furthermore, when moving them on the ground, manual handling is required, which is time-consuming, labor-intensive, and inefficient. Improper handling may even cause materials to slip and be damaged. Summary of the Invention

[0003] The purpose of this invention is to provide a stacking and turnover device for building construction materials. This device solves the technical problems of time-consuming and labor-intensive material transfer, low efficiency, and damage due to slippage in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A material stacking and turnover device for construction includes a movable chassis, support rods, a storage assembly, and a lifting and adjusting assembly. The lifting and adjusting assembly is mounted on the movable chassis and is used to control the vertical movement of multiple support rods. The storage assembly is located on top of the multiple support rods. The storage assembly includes a support plate, an anti-slip layer, and limiting columns. The anti-slip layer is fixedly mounted on the support plate, and the multiple limiting columns are arranged at the top corner of the support plate. An extension hole is provided on one side of the support plate, and an extension member can be detachably installed in the extension hole, connecting two adjacent storage assemblies.

[0005] Preferably, the movable chassis includes a base, wheels, and a vertical adjustment assembly. The vertical adjustment assembly is disposed at the bottom of the base, and the wheels are disposed at the bottom of the vertical adjustment assembly. The vertical adjustment assembly is used to adjust the installation height of the wheels.

[0006] Preferably, the vertical adjustment assembly includes a limiting slider, a vertical lead screw, a drive ring, and a mounting plate. A groove is provided on the base, and the limiting slider is slidably installed in the groove. One end of the vertical lead screw is fixedly installed at the bottom of the limiting slider, and the other end of the vertical lead screw is fixedly installed on the mounting plate. The traveling wheel is fixedly installed at the bottom of the mounting plate. The drive ring is rotatably installed at the bottom of the base. The drive ring and the vertical lead screw are connected by a threaded power connection. When the drive ring is rotated, the vertical lead screw drives the limiting slider to slide in the groove.

[0007] Preferably, the support rod is U-shaped, and a slot is provided on the movable chassis for vertical sliding of the support rod.

[0008] Preferably, four wheels are provided, and the wheels are omnidirectional wheels.

[0009] Preferably, a mounting groove is provided at the bottom of the support plate, and the top of the support rod is disposed in the mounting groove.

[0010] Preferably, the lifting and adjusting assembly includes a dual-output motor, a worm gear, a turbine, and an adjusting screw. Both ends of the adjusting screw are rotatably mounted on a movable chassis. The worm gear is fixedly mounted on the adjusting screw. The support rod is threadedly connected to the adjusting screw. The worm gear is rotatably mounted on the movable chassis. One end of the worm gear is fixedly connected to one end of the dual-output motor, and the other end of the worm gear is connected to the turbine.

[0011] Preferably, the extension member is linear or L-shaped.

[0012] Preferably, a clamping element is adjustablely provided on the support rod, the clamping element being used to clamp the material placed on the storage assembly.

[0013] A method for using a material stacking and turnover device for construction work includes the following steps: Step 1: Material stacking. Based on the size of the materials to be stacked, assemble a movable chassis of the corresponding size and shape, and fix the two ends of the extension piece in the corresponding extension hole so that multiple storage components are fixedly connected. Step two, material transfer: When horizontal movement is required, the operator pushes multiple connected movable chassis to move them horizontally; when lifting is required, multiple lifting and adjusting components are used to lift the stored components, and then a forklift or hoisting equipment is used to lift the multiple stored components simultaneously.

[0014] In this invention, the extension component can connect multiple storage components into a whole, which facilitates the overall stacking and transportation of large and irregularly shaped materials. It eliminates the need to customize special equipment for different materials, reduces equipment investment costs, and improves resource utilization.

[0015] By driving the support rod to move vertically through the lifting and adjusting components, a stable operating gap can be formed between the storage components and the movable chassis. This solves the problem of forklift forks being difficult to insert accurately in traditional stacking methods, allowing the transfer equipment to quickly position and lift materials at once without repeated manual adjustment or handling. This significantly shortens the transfer preparation time, greatly improves operational efficiency, and reduces manpower input and labor intensity.

[0016] The anti-slip layer in the storage components increases the friction between the turnover materials and the support plate. Combined with the limiting columns at the corners, it can limit the stacked materials in the horizontal direction, effectively preventing the materials from slipping due to bumps or tilting during movement or transfer. Compared with the instability of traditional square timber supports, the structured support design of this device makes the material stacking more stable, reduces the risk of material deformation and damage caused by improper support, and reduces construction cost waste.

[0017] The mobile chassis is equipped with omnidirectional wheels, enabling the device to flexibly adapt to the material transfer needs of different areas on the construction site and complete short-distance movement without relying on large equipment. The vertical adjustment component at the bottom can adjust the height of the wheels by rotating the drive ring, and can be individually leveled for uneven ground to ensure that the device always remains horizontal and stable, avoiding tilting of material stacks due to ground problems and improving the applicability of the device in complex construction environments.

[0018] The lifting and adjusting assembly uses a dual-output motor with a worm gear drive to achieve synchronous lifting of multiple support rods, ensuring balanced force on the stored components and preventing device jamming or material displacement due to uneven force during lifting. The overall structure features a modular design with reliable connections between components. Operation can be completed simply by controlling the motor to start or stop or rotating the drive ring, requiring no professional skills, lowering the barrier to entry for operators and improving the convenience of on-site operations.

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 6 The illustrated material stacking and turnover equipment for construction includes a movable chassis 1, a support rod 2, a storage component 3, a lifting and adjusting component 4, and an extension component 5; the materials to be stacked are placed on the storage component 3.

[0021] The movable chassis 1 includes a base 10, wheels 11, and a vertical adjustment assembly. The vertical adjustment assembly is located at the bottom of the base 10, and the wheels 11 are located at the bottom of the vertical adjustment assembly. The vertical adjustment assembly is used to adjust the installation height of the wheels 11. Specifically, the vertical adjustment assembly includes a limiting slider 12, a vertical lead screw 13, a drive ring 14, and a mounting plate 15. A groove 16 is provided on the base 10, and the limiting slider 12 is slidably installed in the groove 16. One end of the vertical lead screw 13 is fixedly installed at the bottom of the limiting slider 12, and the other end of the vertical lead screw 13 is fixedly installed on the mounting plate 15. The wheels 11 are fixedly installed at the bottom of the mounting plate 15. The drive ring 14 is rotatably installed at the bottom of the base 10. The drive ring 14 and the vertical lead screw 13 are connected by a threaded power connection. When the drive ring 14 is rotated, the vertical lead screw 13 drives the limiting slider 12 to slide within the groove 16. When the ground is uneven, the operator can adjust the vertical adjustment components to make the top of the movable chassis 1 level and stable.

[0022] In one embodiment, four casters 11 are provided, and the casters 11 are omnidirectional wheels. The four casters 11 are arranged at the four corners of the bottom of the base 10.

[0023] The support rod 2 is U-shaped and has slots on the movable chassis 1 for vertical sliding at both ends. Driven by the lifting and adjusting assembly 4, the two ends of the support rod 2 move vertically along the slots, causing the bottom surface of the storage assembly 3 to separate from the top surface of the base 10, forming an operating gap. Forklifts or other transfer equipment can lift and transfer the storage assembly 3 through this operating gap.

[0024] The storage component 3 is positioned on top of multiple support rods 2, and under normal conditions, the bottom surface of the storage component 3 is in contact with the top surface of the movable chassis 1. The storage component 3 includes a support plate 30, an anti-slip layer 31, and limiting posts 32. The anti-slip layer 31 is fixedly mounted on the support plate 30, and the multiple limiting posts 32 are arranged inside the top corners of the support plate 30. Specifically, a mounting groove corresponding to the support rods 2 is provided at the bottom of the support plate 30, and the top of the support rods 2 is positioned within the mounting groove to ensure reliable installation.

[0025] The lifting and adjusting assembly 4 is mounted on the movable chassis 1 and is used to control the vertical movement of multiple support rods 2. The lifting and adjusting assembly 4 includes a dual-output motor 40, a worm gear 41, a worm wheel 42, and an adjusting screw 43. Both ends of the adjusting screw 43 are rotatably mounted on the movable chassis 1 via bearings. The worm gear 41 is fixedly mounted on the adjusting screw 43. The support rods 2 are threadedly connected to the adjusting screw 43. The worm gear 41 is rotatably mounted on the movable chassis 1 via a support. One end of the worm gear 41 is fixedly connected to one end of the dual-output motor 40, and the other end is poweredly connected to the worm wheel 42. When the dual-output motor 40 is energized and rotates, it drives the two worm gears 41 to rotate synchronously. The worm wheel 42, which meshes with the worm gears 41, rotates accordingly, thereby driving the adjusting screw 43 to rotate, and ultimately driving the support rods 2 to move vertically.

[0026] An extension hole 6 is provided on one side of the support plate 30. An extension component 5 can be detachably installed within the extension hole 6, connecting two adjacent storage components 3 to form a single unit. The extension component 5 is linear or L-shaped. When the material to be stacked is safety netting, a single storage component 3 is used for storage without connection via the extension component 5. When the material to be stacked is scaffolding steel pipe or ordinary formwork, the storage components 3 are spliced ​​or not, depending on their length, with the spliced ​​length matching the length of the material. When the material to be stacked is L-shaped formwork, multiple storage components 3 of corresponding shape and size are spliced ​​according to the dimensions of the L-shaped formwork.

[0027] A clamping element 7 is adjustablely installed on the support rod 2. The clamping element 7 is used to clamp the material placed on the storage component 3. The clamping element 7 is a pressure block that is slidably installed on the support rod 2. The pressure block is fixedly connected to the support rod 2 by bolts. The stability of the material transfer process is improved by the clamping of multiple pressure blocks.

[0028] A method for using a material stacking and turnover device for construction work includes the following steps: Step 1: Material stacking. Based on the size of the material to be stacked, assemble the corresponding number of movable chassis 1 so that the overall size and shape of the multiple movable chassis 1 after assembly are adapted to the material. Fix the two ends of the extension piece 5 in the corresponding extension hole 6 with fasteners so that the multiple storage components 3 are fixedly connected.

[0029] Step 2, material transfer: When horizontal movement is required, the operator pushes or uses mechanical devices to move multiple connected movable chassis 1 horizontally; when lifting is required, multiple lifting adjustment components 4 are used to lift the storage components 3 simultaneously, and then a forklift or lifting equipment is used to lift the multiple storage components 3 simultaneously.

[0030] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
