Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical transfer tools, specifically relating to a lightweight hydraulic lifting tool for building blocks. Background Technology

[0002] In the field of construction engineering, autoclaved aerated concrete (AAC) blocks are widely used in group buildings and large-scale projects due to their advantages such as lightweight, thermal insulation, strong construction adaptability, and high strength. However, in actual construction, the low efficiency and high loss rate of block handling have long plagued construction companies. Traditional handling methods mainly rely on manual operation, including workers manually carrying blocks to wheelbarrows and then transporting them to the usage site for unloading one by one. In hoisting operations, hoppers are usually used for block transportation, but this requires repeated manual loading and unloading, which is not only labor-intensive and inefficient but also prone to problems such as block breakage, chipping, and corner damage during handling, increasing the material waste rate. In addition, manual handling may cause hand injuries to operators, further affecting construction safety and progress. Although existing hopper hoisting methods can achieve a certain scale of transportation, the impact and collision caused by directly dumping blocks make it difficult to avoid material loss, which cannot meet the needs of large-scale, high-efficiency construction. Therefore, how to optimize the block handling process, reduce the loss rate, and improve transportation efficiency has become an urgent problem to be solved in construction technology.

[0016] Flexible adaptation to different handling needs: Batch handling mode (M-type clamping) is suitable for stacked blocks, while scattered handling mode (lifting rod bearing) is suitable for small quantities of blocks, meeting the needs of different construction scenarios. The clamping force can be adjusted by telescopic rods to adapt to blocks of different sizes, improving versatility.

[0017] Simple structure, economical and practical: It adopts a square steel welded frame + standard hydraulic components, which has low manufacturing cost, convenient maintenance, and is suitable for wide application on construction sites.

[0036] Conventional autoclaved aerated concrete (AAC) block transportation and use, such as Figure 4 As shown

[0037] 1. Initial Preparation

[0038] Connect the device to the hook of the crane or tower crane via the lifting ring 6 to ensure lifting stability. Check whether the hydraulic oil pump 4 is working properly, ensure that the telescopic rod 3 can extend and retract freely, and confirm that the anti-slip rubber pad 241 of the clamping part 24 is intact to prevent the block from slipping or being damaged. Hang the four sets of lifting rod hanging rings 55 on the corresponding hooks 52 respectively.

[0039] 2. Clamping blocks

[0040] Operate the crane to lower the device above the block pile to be transported, adjust the position so that the fixing component 1 is directly above the block pile, start the hydraulic oil pump 4 to push the hydraulic oil pump rod 41, so that the bracket 21 moves upward, driving the first connecting rod 22 and the second connecting rod 23 to move. Since the four sets of first connecting rods 22 and second connecting rods 23 are in two pairs of M-shaped symmetrical structures, their movement will cause the clamping part 24 to tighten inward, thereby clamping the block pile. If the block pile is wide, the clamping force can be adjusted by adjusting the telescopic rod 3 to ensure a stable grip.

[0041] 3. Hoisting and transporting blocks

[0042] After the blocks are clamped, the crane slowly lifts the lifting ring 6, so that the entire device and blocks rise together. During transportation, the movement is kept stable to prevent shaking that could cause the blocks to loosen or fall off.

[0043] 4. Unloading the blocks

[0044] Upon reaching the target position, the crane slowly lowers the device, allowing the block stack to land smoothly. The hydraulic oil pump 4 is operated to supply oil in reverse, causing the hydraulic oil pump rod 41 to retract and drive the support 21 to move downward. At this time, the first connecting rod 22 and the second connecting rod 23 unfold outward, the clamping part 24 is released, and the unloading is completed.

[0045] Small quantities and loose blocks are transported by direct hoisting, and when used... Figure 5 As shown

[0046] 1. Initial Preparation

[0047] The device is connected to the hook of a crane or tower crane via the lifting ring 6 to ensure lifting stability. The four sets of lifting rod hanging rings 55 are removed from the corresponding hooks 52.

[0048] 2. Clamping blocks

[0049] Operate the crane to lower the device above the block pile to be transported, adjust the position so that the fixing component 1 is directly above the block pile, and place a small number and scattered blocks on the lifting rod 53 and the lifting rod support 54.

[0050] 3. Hoisting and transporting blocks

[0051] The crane slowly lifts the lifting ring 6, raising the entire device along with the blocks. During transportation, it maintains a smooth movement to prevent shaking that could cause the blocks to loosen or fall off.

[0052] 4. Unloading the blocks

[0053] Upon reaching the target location, the crane slowly lowers the device to unload a small amount of loose blocks, and the four sets of lifting rod rings 55 are respectively hung on the corresponding hooks 52.

[0054] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
