Embodiment approach
[0022] As an embodiment of the present invention, an air storage box 13 is provided on one side of the No. 1 cylinder 21; the gas storage box 13 is used to store the gas produced by the compression of the No. The gas in the cylinder is delivered to the No. 1 cylinder 21 to realize the locking of the No. 1 cylinder 21. In the hoisting of objects, due to the heavy weight of the hoisted objects, the cylinder shaft in the No. 1 cylinder 21 is prone to shaking, thereby affecting the stability of object retrieval; 13 Store the gas produced by the No. 1 cylinder 21, and transport the gas to the No. 1 cylinder 21, and lock the No. 1 cylinder 21 to prevent the cylinder shaft in the No. 1 cylinder 21 from shaking, which will affect the stability of object lifting , thereby improving the safety of object lifting.
[0023] As an embodiment of the present invention, the number of teeth of the left gear in the differential 24 is less than that of the right gear in the differential 24, so t...

Abstract
The invention belongs to the technical field of lifting appliances, in particular to a lifting appliance. The lifting appliance comprises a lifting ring, a first shell and a second shell. The liftingappliance further comprises a driving unit, a grabbing unit, a clamping unit and a controller. On the one hand, the lifting ring is pulled, and according to the size of the object to be grasped, through the mutual cooperation between a first cylinder, a differential mechanism, a first worm, a first slide block, a rack, a first gear, a second worm, a third worm and a second slide block, the secondworm and the third worm rotate towards the side close to the first gear, so that the grasping unit tightly clamps the object, and the object is prevented from falling off in the lifting process, so that the lifting safety of the object lifting is improved; and on the other hand, during lifting of the lifting ring, a fixing plate presses a first air bag, and the gas generated by the first air bag is used for lifting the object, so that additional power equipment is avoided, the overall weight of the lifting tool is increased, the weight of the lifting tool for lifting the object is influenced,and the practicability of the lifting tool is improved.
Description
technical field [0001] The invention belongs to the technical field of slings, in particular to a sling. Background technique [0002] The spreader refers to the device for lifting heavy objects in the hoisting machinery; the most commonly used spreaders for lifting the finished items are hooks and slings, and others include rings, lifting suction cups, clamps and forks; they are widely used in the lifting industry. [0003] In the prior art, there is also a technical solution of a patent on a suspension. For example, a Chinese patent with application number 2015108369714 discloses a cylinder suspension, which includes a suspension ring, a cross bar, and a grabbing device. The suspension ring passes through the The cross bar is arranged above the grabbing device to provide a lifting point for suspending the grabbing device; the hanger also includes a clamping device; the grabbing device includes a left ratchet, a right ratchet Claws, the left and right pawls are symmetrica...
