Description

Technical Field

[0001] This utility model relates to the field of granite slab laying technology, specifically an outdoor granite slab laying device. Background Technology

[0002] Granite slabs are widely used in outdoor architectural decoration and ground paving projects due to their aesthetic appeal and durability. However, the installation process of granite slabs presents numerous challenges. Traditional installation methods rely primarily on manual labor, requiring workers to move heavy granite slabs and precisely position and secure them during installation. This method is not only labor-intensive and inefficient but also prone to unevenness and slab damage due to human error, thus affecting the overall installation quality and lifespan.

[0003] Furthermore, laying granite slabs typically requires the collaboration of multiple people, increasing the complexity of construction and communication costs. In some complex paving scenarios, such as large plazas, sidewalks, or slopes, the limitations of traditional paving methods become even more apparent, making it difficult to meet the high demands of modern construction for efficiency and quality.

[0004] To address these issues, some auxiliary laying tools have emerged on the market. However, most of these tools are single-function and cannot simultaneously meet the multiple needs of slab handling, positioning, fixing, and adjustment. Therefore, developing a device that can efficiently and conveniently complete the laying of granite slabs is of great significance for improving construction efficiency, reducing labor intensity, and enhancing laying quality.

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-7 This embodiment provides an outdoor granite slab laying device, including a vertically arranged main frame 4. A right-angle clamp 9 is fixedly installed on the lower front surface of the main frame 4. An installation groove 5 is provided on the lower surface of the main frame 4. A rotating arm 12 is rotatably installed inside the installation groove 5. An L-shaped clamp 10 is provided at the front end of the rotating arm 12. The lower side of the rotating arm 12 is fixedly connected to the main frame 4 by a tension spring 6. A support is provided near the lower rear end of the main frame 4. A fixed shaft 7 is provided inside the support. Wheels 8 are rotatably connected to both ends of the fixed shaft 7. The granite slab is fixed to the main frame 4 by the right-angle clamp 9 and the L-shaped clamp 10. The design of the rotating arm 12 and the L-shaped clamp 10 allows the granite slab to be easily adjusted in position and angle. The tension spring 6 provides elastic support to ensure the stability and flexibility of the rotating arm 12. The design of the wheels 8 allows the device to be easily moved to a designated position, improving laying efficiency.

[0018] Connecting rods 3 are fixedly installed on both sides of the upper end of the main frame 4, and fixed hollow handles 1 are fixedly installed on the upper ends of the connecting rods 3. A rotating rod 2 is rotatably installed inside the fixed hollow handle 1, and a take-up roller 13 is fixedly installed on the middle surface of the rotating rod 2 between the two fixed hollow handles 1. The take-up roller 13 is connected to the rotating arm 12 by a steel wire rope. The design of the fixed hollow handle 1 allows the operator to easily grip the device for movement and operation. The design of the rotating rod 2 allows the take-up roller 13 to rotate flexibly, and the opening and closing of the rotating arm 12 is achieved by the winding and unwinding of the steel wire rope, improving the convenience of operation.

[0019] In this embodiment, rubber pads are provided on the inner sides of the L-shaped clamping rod 10 and the right-angle clamping plate 9 to increase friction and provide some protection for the granite slab. The L-shaped clamping rod 10 is telescopically fixed to the front end of the rotating arm 12. Specifically, the L-shaped clamp 10 is inserted into the rotating arm 12. A limiting mechanism 14 is provided on the upper surface of the front end of the rotating arm 12. The limiting mechanism 14 includes a pull rod 15, a compression spring 16, a limiting plate 17, and a sleeve 18. The sleeve 18 is fixedly installed on the upper end of the rotating arm 12. A blocking part extends inward from the upper end of the sleeve 18. A through hole is formed in the center of the blocking part. The pull rod 15 includes a pull rod body that is slidably connected to the through hole. A pull cap extends outward from the upper end of the pull rod body. A slider that is slidably connected to the sleeve 18 is provided at the lower end of the pull rod body. A compression spring 16 is sleeved on the outside of the pull rod 15. The two ends of the compression spring 16 abut against the blocking part and the slider, respectively. The lower end of the slider is fixedly connected to the limiting plate 17. A number of limiting grooves 11 are provided on the surface of the L-shaped clamp 10. The limiting grooves 11 are inserted into the limiting plate 17.

[0020] The design of the limiting groove 11 allows the L-shaped clamping rod 10 to be adjusted in position as needed. The insertion connection between the limiting plate 17 and the limiting groove 11 ensures the stability of the L-shaped clamping rod 10 and prevents accidental movement during laying. The compression spring 16 provides elastic support for the pull rod 15 and the limiting plate 17, allowing the limiting plate 17 to automatically reset. The sleeve 18 provides a stable sliding path for the limiting plate 17, ensuring that the limiting plate 17 can be accurately inserted into the limiting groove 11, thereby fixing the position of the L-shaped clamping rod 10.

[0021] When in use, the device is supported on the ground by wheels 8, which makes it easy to move and operate. The rotating arm 12 is connected to the main frame 4 by tension spring 6 and is in a natural hanging state. The L-shaped clamp 10 is inserted into the sliding groove on the inner side of the rotating arm 12 and fixed by the limiting mechanism 14.

[0022] The operator moves the device to the desired location for laying the granite slab by fixing the hollow handle 1 and placing the right-angle clamp 9 against the back of the granite slab. The operator then rotates the take-up roller 13 via the rotating rod 2, which pulls the rotating arm 12 upwards via the wire rope, adjusting it to a suitable angle to secure the granite slab inside the L-shaped clamp 10. Afterwards, the operator pushes the device by fixing the hollow handle 1, moving the wheel 8 to lay the granite slab in the predetermined position. During the laying process, the right-angle clamp 9 assists in fixing the granite slab, ensuring stability and accuracy. Adjusting the rotating arm 12 ensures the granite slab is positioned correctly.

[0023] When the position of the L-shaped clamp 10 needs to be adjusted, the operator pulls the limiting plate 17 through the pull rod 15 to disengage it from the limiting groove 11. After the position of the L-shaped clamp 10 is adjusted, the pull rod 15 is released, and the limiting plate 17 is reinserted into the limiting groove 11 under the action of the compression spring 16, fixing the L-shaped clamp 10 in the new position.

[0024] The overall structure of this utility model is compact, and the connections between the components are firm. The main components, such as the swivel arm 12, the tension spring 6, and the limiting mechanism 14, are all made of high-strength materials, which can withstand large construction loads, have a long service life, low maintenance costs, and are suitable for long-term use in complex outdoor environments.

[0025] 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.
