Description

Technical Field

[0001] This invention relates to the technical field of building construction, specifically to a masonry loading and unloading clamp and a masonry transportation device. Background Technology

[0002] With the continuous development of cities, since the beginning of the 21st century, with the rapid pace of economic development and urban construction in my country, the number of buildings in cities has gradually increased. Frame structures and brick-concrete structures now occupy a significant share in urban architecture. To better divide space and provide a higher quality living environment, a large number of masonry walls are often incorporated into frame and brick-concrete structures. Traditionally, the loading, unloading, and horizontal and vertical transportation of masonry materials are done manually, with cranes used in conjunction with manual lifting. This method of manual labor combined with lifting equipment is not only slow but also physically demanding, inefficient, and costly. Furthermore, safety cannot be guaranteed during horizontal and vertical transportation, and flexible transport and accurate placement are often difficult to achieve during construction. Summary of the Invention

[0050] The masonry loading and unloading clamp of this embodiment can clamp masonry materials in the front-to-back direction using the first and second clamping plates, and then position the masonry in the left-to-right direction using the first and second fixing plates. Other hoisting equipment can then be used for loading, unloading, and horizontal and vertical transportation of the masonry materials. The overall structure of the device is safer, more stable, simpler, and easier to operate. It ensures the safety of masonry materials during loading, unloading, and horizontal and vertical transportation, improves construction efficiency, and effectively avoids the low efficiency and personnel safety issues associated with conventional manual labor or manual labor combined with hoisting equipment.
