Description

Technical Field

[0001] This utility model relates to the field of stacking crane technology, specifically a concrete brick stacking crane. Background Technology

[0002] Stacker cranes are engineering machines specifically designed for stacking, handling, and loading / unloading goods. They are widely used in construction projects, ports, storage yards, logistics centers, and other scenarios. They are particularly adept at handling packaged, palletized, or containerized goods, enabling vertical lifting and horizontal movement of goods to complete multi-layer stacking operations.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN216613916U) discloses a stacker crane, comprising a base. Two fixed brackets are fixedly mounted on the upper surface of the base, and an mounting plate is fixedly mounted between the two brackets. Two guide plates are fixedly mounted on the lower surface of the mounting plate, and an electric push rod is fixedly mounted on the lower surface of the guide plate. A connecting plate is fixedly mounted on the lower surface of the electric push rod, and a long plate is fixedly mounted on the lower surface of the connecting plate. A moving device is provided on the lower surface of the base, comprising a support column. An anti-slip pad is fixedly mounted on the lower surface of a pad block. A through groove is formed inside the support column, and a connecting rod is rotatably mounted inside the through groove. A caster wheel is fixedly mounted on the free end of the connecting rod, and a first spring is fixedly mounted between the connecting rod and the base. This invention solves the problem of disassembling and transporting the stacker crane, which is extremely inconvenient.

[0004] Although the aforementioned patent improves the efficiency of lifting by using components such as guide plates, electric push rods, and connecting rods, and by cooperating with each component to utilize multiple pressure plates, and by cooperating with the first spring, base, and connecting rod to improve the disassembly and transportation efficiency of the stacker crane, in the stacking and lifting of materials, it is often necessary to lift goods of different sizes. Although this component can improve efficiency through multiple pressure plates, the lifting size is relatively closed. When stacking large-sized goods, it is also necessary to change the lifting mold, which increases costs and the labor intensity of operators, which is not conducive to improving the applicability of the device.

[0005] Therefore, this utility model provides a concrete brick stacking crane to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] This utility model provides a concrete brick stacking crane, such as Figures 1-5 As shown, the concrete brick stacking crane includes a clamping seat 1, a clamping assembly is provided inside the clamping seat 1, and a lifting assembly is provided at the top of the clamping seat 1.

[0029] The clamping assembly includes a bidirectional lead screw 2 rotatably connected to the inner wall of the clamping seat 1, a displacement seat 3 threadedly sleeved on the outer wall of the bidirectional lead screw 2, a drive groove 4 opened in the middle of the clamping seat 1, a driven tooth 5 fixedly sleeved on the outer wall of the bidirectional lead screw 2 at the drive groove 4, a pneumatic motor 6 installed on the outer wall of the clamping seat 1, and a drive gear 7 coaxially driven at the output end of the pneumatic motor 6.

[0030] The clamping assembly also includes a pneumatic clamp 8 installed at the bottom of the displacement seat 3. A clamping plate 9 is slidably connected to the inner wall of the pneumatic clamp 8, and an anti-slip strip is fixedly connected to the outer wall of the clamping plate 9.

[0031] Specifically, the clamping seat 1, in conjunction with the clamping assembly, enhances stability during the stacking and lifting of concrete bricks through the coordinated operation of its components, preventing the risk of falling during transportation. When lifting stacked bricks of different sizes, the pneumatic motor 6 is activated, causing it to rotate. The output of the pneumatic motor 6, via a coaxially driven drive gear 7, drives the driven gear 5 located in the drive groove 4 in the center of the clamping seat 1. Because the two mesh and the diameter of the drive gear 7 is smaller than that of the driven gear 5, the drive gear 7 slowly rotates the driven gear 5, thus improving the stability of the driven gear 5 and the bidirectional lead screw 2 during rotation. When the bidirectional lead screw 2 rotates, its outer wall is threaded with a displacement seat 3, which slides and limits the rotation of the drive gear 5. The two displacement seats 3 will also move in opposite directions, thereby adjusting the positions of themselves and the pneumatic clamps 8 installed below them. By adjusting the positions, the applicability of the device can be improved, expanding its application range for lifting and stacking. This avoids the need to change clamps according to different stacking sizes, further improving stacking efficiency and reducing the labor intensity of operators. Through the pneumatic clamps 8 and the sliding clamps 9 on their inner walls, compressed gas can be used to make the clamps 9 slide quickly inside the pneumatic clamps 8, thereby quickly clamping the bricks to be lifted. Since multiple anti-slip strips are fixedly connected to the outer wall of the clamps 9, the contact area with the bricks can be increased by using the anti-slip strips, avoiding the phenomenon of loose clamping, and further improving the safety and stability of lifting. This component has a simple structure, strong practicality, and can improve the applicability and work efficiency of the device.

[0032] The lifting assembly includes a crane 10, with a lifting boom 11 rotatably connected to the output end of the crane 10, and a winch 12 installed at the bottom end of the lifting boom 11.

[0033] The output end of the winch 12 is fixedly connected to the top of the clamping seat 1 via a steel strand 13. A support plate 14 is fixedly connected to the side wall of the lifting arm 11, and an air pump 15 is installed on the top of the support plate 14.

[0034] One of the output ends of the air pump 15 is fixedly connected to the input end of one of the pneumatic clamps 8 via an air pipe 16, and the upper top ends of the two pneumatic clamps 8 are fixedly connected via a connecting pipe 17.

[0035] Another output end of the air pump 15 is fixedly connected to an elastic hose 18, and the end of the elastic hose 18 is fixedly connected to the input end of the pneumatic motor 6.

[0036] Specifically, the lifting assembly allows for stable transport of concrete bricks during the stacking process through the coordinated operation of its components, ensuring rapid stacking. The crane 10 and its end connecting plate facilitate quick and stable connection to various environments, guaranteeing stability during lifting and preventing tipping due to excessive weight. The rotating lifting arm 11 at the output end of the crane 10 expands the lifting range and allows for rapid lifting of goods from different directions. The lifting arm 11, in conjunction with the winch 12, drives the steel strand 13 to wind up and down, adjusting the height of its end clamp 1 to allow for longitudinal stacking of the stacked bricks, minimizing space requirements. Meanwhile, by increasing the number of stacks, the support plate 14 installed on the side wall of the lifting arm 11 can provide sufficient stability for the air pump 15, ensuring the stability of the air pump 15 during use. The air pump 15 can then deliver compressed air to the interior of the pneumatic clamp 8 via the air pipe 16, enabling the pneumatic clamp 8 to quickly clamp the bricks. Since the upper tops of the two pneumatic clamps 8 are connected by the connecting pipe 17, the two clamps can operate simultaneously when the gas is delivered to the interior of the pneumatic clamp 8, maintaining equal clamping force and preventing tilting to one side during clamping. Through the setting of the elastic hose 18, the air pump 15 can deliver compressed air to the pneumatic motor 6, enabling it to run quickly and drive the two displacement seats 3 to adjust their positions, so as to quickly adapt to different concrete brick stacks.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
