Description

Technical Field

[0001] This utility model relates to the field of building material handling equipment, and in particular to a concrete slab flipping and handling device. Background Technology

[0002] A concrete slab turning and handling device is a mechanical device specifically designed for handling and turning concrete slabs. Through its mechanical structure and automated control system, it achieves efficient handling, turning, and unloading of concrete slabs, and is widely used in building construction, precast component production, and other fields. The device is designed to improve construction efficiency, reduce manual labor intensity, and ensure operational safety and reliability.

[0003] In existing concrete slab handling and flipping operations, manual handling or simple mechanical auxiliary equipment is usually used. The specific operation steps are as follows: workers move the concrete slabs from the storage location to the designated construction location. This usually requires the cooperation of multiple people and the use of tools such as crowbars and ropes to assist in the handling. In some cases, simple transport carts or handcarts are used. The concrete slabs are placed on the carts and the transport carts are pushed or pulled by manpower to reach the designated location. When it is necessary to flip the slabs, workers usually need to use crowbars or other tools to manually flip the slabs to the required angle. After reaching the designated location, workers need to manually unload the slabs from the transport equipment and place them at the construction location.

[0004] Existing technologies for manually handling and flipping concrete slabs require a large workforce, resulting in high labor intensity and low efficiency, especially when the slabs are heavy or the construction environment is complex, easily leading to worker fatigue and operational errors. Secondly, while simple mechanical auxiliary equipment can reduce some labor intensity, its functions are relatively limited, and manual intervention is still required during flipping and unloading, posing certain safety hazards.

[0030] Reference Figure 3The auxiliary unloading structure 8 includes a support plate 803, which is fixedly connected to the top of the adjusting plate 3. The support plate 803 provides an installation position for the threaded rod B804. The threaded rod B804 is connected through the outer side of the support plate 803. The threaded rod B804 is used to drive the threaded sleeve B805 to move. One end of the threaded rod B804 is rotatably connected to the inner side of the support plate 803 through a bearing. The bearing ensures that the threaded rod B804 can rotate smoothly. The other end of the threaded rod B804 is fixedly connected to a driven gear 706. The driven gear 706 meshes with the arc-shaped toothed plate 802, driving the threaded rod B804 to rotate. An extension block 801 is fixedly connected to the front of the base plate 1. The extension block 801 is used to support the arc-shaped toothed plate 802. The top of the extension block 801 is fixedly connected to the arc-shaped toothed plate 802. 2 meshes with driven gear 706, guiding the movement of driven gear 706. The front of driven gear 706 meshes with the back of arc-shaped toothed plate 802, realizing the rotation control of threaded rod B804.

The bottoms of threaded sleeve B805 and push plate 806 both contact the top of adjusting plate 3, ensuring that push plate 806 can smoothly push concrete slabs.

[0031] Reference Figure 4 The top of the adjusting plate 3 is equipped with a fixing structure 9, which includes a limiting block 902. A threaded rod C903 is threadedly connected to the front of the limiting block 902. The threaded rod C903 is used to move the abutment plate 901, thus fixing the concrete slab. The back of the threaded rod C903 is rotatably connected to the abutment plate 901 via a bearing. The abutment plate 901 contacts the concrete slab through a rubber pad, providing fixation and protection. A rubber pad is fixedly connected to the back of the abutment plate 901, serving as an anti-slip and cushioning device to prevent damage to the concrete. The front of the threaded rod C903 is fixedly connected to a knob 904. The knob 904 allows the operator to easily rotate the threaded rod C903. The bottom of the abutment plate 901 contacts the top of the adjusting plate 3 to ensure that the abutment plate 901 can move smoothly. The top of the adjusting plate 3 has two arc-shaped grooves 905, which provide sliding tracks for the balls 906. The bottom of the abutment plate 901 is fixedly connected to two balls 906, which slide in the arc-shaped grooves 905 to reduce the friction when the abutment plate 901 moves.

[0032] Working principle: First, the concrete slab is moved to the top of the adjusting plate 3, ensuring that the slab is placed stably and in the correct position. Next, by rotating the knob 904, the threaded rod C903 drives the abutment plate 901 forward. The abutment plate 901 makes close contact with the concrete slab through the rubber pad on its back, thus firmly fixing the slab to the adjusting plate 3. At this time, the ball bearing 906 slides in the arc-shaped groove 905, ensuring that the abutment plate 901 moves smoothly and stably.

[0033] Then, grasp the handle 5 and push the device to the appropriate position. During the movement, the device moves flexibly through the four corners of the bottom of the base plate 1. The rubber sleeve 6 provides the operator with a non-slip and comfortable grip, ensuring the convenience and safety of the pushing process. After reaching the designated position, turn the knob 904 again to make the threaded rod C903 drive the abutment plate 901 to move backward, releasing the fixation on the concrete slab. At this time, start the motor 701 through the control panel 10. The output shaft of the motor 701 drives the threaded rod A702 to rotate. The rotation of the threaded rod A702 causes the threaded sleeve A703 to move along its axis. The threaded sleeve A703 adjusts the angle of the adjusting plate 3 through the first connecting rod 704. At the same time, the slider 705 slides along the guide rod on the inner side of the second extension frame. The second connecting rod 707 assists in the smooth movement of the adjusting plate 3, realizing the angle change of the adjusting plate 3. During the angle adjustment of the adjusting plate 3, the driven gear 706 moves along the arc-shaped toothed plate 802. The rotation of the driven gear 706 drives the threaded rod B804 to rotate, and the rotation of the threaded rod B804 causes the threaded sleeve B805 to move along its axial direction. The threaded sleeve B805 drives the push plate 806 to move on the adjusting plate 3. When the angle of the adjusting plate 3 is adjusted to the appropriate position, the push plate 806 pushes the concrete slab out along one side of the adjusting plate 3, thereby realizing the unloading operation of the concrete slab.

[0034] After unloading is completed, the motor 701 is reversed via the control panel 10 to restore the adjusting plate 3 to a horizontal state. Then, the device is moved to the starting position, ready for the next handling and unloading operation. The entire process is simple to operate and can efficiently and safely complete the handling and flipping of concrete slabs. At the same time, the auxiliary unloading structure 8 enables rapid unloading, improving work efficiency.

[0035] 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.
