Description

[0002] In recent years, the production scale of prefabricated components for high-speed railways has been expanding, among which the production demand for prefabricated concrete cover plates is huge. Since prefabricated components are not designed with lifting holes and cannot be equipped with lifting embedded parts, there are problems such as difficult transportation and heavy workload during the production process.

[0003] The general methods of transporting concrete cover slabs are divided into manual transport and auxiliary mechanical gripper transport. Existing auxiliary mechanical grippers mostly adopt a clamping structure. When working, the gripper is manually aligned with the side edge of the cover slab to grab and lift it, and a large working space is required. When the concrete cover slabs are stacked tightly, this type of machine cannot be used. In actual use, after the gripper grabs the cover slab, the friction between the gripper and the side edge of the cover slab cannot be controlled and will be affected by the environment, which may easily cause a safety hazard of slipping.

[0004] In addition, the existing lifting equipment has a large structure and size, which is not conducive to mechanical operation in a small space environment. This results in manual handling during construction, which affects the efficiency of transportation. Utility Model Content
