Problems solved by technology
[0002] A prefabricated concrete slab with T-shaped ribs developed by the applicant has many advantages such as convenient use and high strength. However, because the shape of the slab is a non-standard part, the existing lifting device needs to manually separate the lifting claws before placing it in use. Hoisting after the hoisting position, the disadvantage of this kind of sling is: when the accuracy of manual operation is not good, it is prone to hoisting crisis and low work efficiency

The invention provides a sling with a T-type rib and for a concrete slab. The sling comprises a support of a quadrangle shape, each right-angle portion is provided with two clamping devices, every two clamping devices form a set, and each clamping device comprises four connection plates. The four connection plates of each clamping device are connected in the structure that the first connection plate on the upper portion is hinged to one end of the second connection plate through a first hinge shaft, the other end of the first connection plate is hinged to one end of the third connection plate, and the other end of the second connection plate is hinged to one end of the fourth connection plate. The first hinge shafts and second hinge shafts of every two clamping devices are coaxial, the bending ends of every two longitudinally distributed clamping devices are connected through fixing rods, two second hinge shafts of every four longitudinally distributed clamping devices are fixedly provided with a connection cylinder, the inside of each connection cylinder is provided with a push rod in the length direction, the inside of each connection cylinder is at least provided with a baffle, and springs are disposed between the baffles and sliding blocks. The sling is used for overcoming defects in the prior art.
Description
technical field [0001] The invention relates to a hoisting appliance in the construction field, which is a special hoisting appliance for concrete slabs with T-shaped ribs. Background technique [0002] A prefabricated concrete slab with T-shaped ribs developed by the applicant has many advantages such as convenient use and high strength. However, because the shape of the slab is a non-standard part, the existing lifting device needs to manually separate the lifting claws before placing it in use. Lifting after the hoisting position, the disadvantage of this kind of sling is: when the accuracy of manual operation is not good, it is prone to hoisting crisis and the work efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a special spreader for concrete slabs with T-shaped ribs, which is used to solve the deficiencies in the prior art. [0004] In order to achieve the above object, the present invention is achieved through...
