Lifting device of folding arm type lifting equipment

Abstract

The invention provides a lifting device of folding arm type lifting equipment. The lifting device of the folding arm type lifting equipment comprises a hanging bracket and a swing frame. A locking device is arranged on the hanging bracket, and two or more positioning pin sets are arranged on the upper surface of the hanging bracket. A steel wire rope is arranged at the center of the hanging bracket. The swing frame is hinged to lifting arms of the folding arm type lifting equipment through swing frame hinged shafts, and swing frame driving devices are arranged on the lifting arms. The swing frame is provided with positioning pin sleeves for positioning pins in the positioning pin sets to be inserted. Through the arrangement, when cargo is lifted, the locking device is reliably connected with the cargo, and the steel wire rope tightens the hanging bracket to enable the positioning pins to be matched with the positioning pin sleeves, so that the cargo, the hanging bracket and the swing frame are connected into a whole; the swing frame driving devices adjust the posture of the swing frame timely to achieve rigid connection to the cargo, in the process from lifting to lowering of the cargo, the degree of freedom of the cargo is restricted, and the cargo is not able to freely move and not affected by external factors, so that the cargo is safely and reliably lifted; and the labor intensity and danger of workers are greatly reduced.

Description

technical field [0001] The invention relates to box body transportation equipment, in particular to a folding arm type hoisting equipment spreader. Background technique [0002] When transporting batches of goods, in order to ensure the safety of the transportation process and the convenience of transshipment, the goods are generally packed into boxes for transportation. For example, ocean shipping generally uses general-purpose boxes to transport goods, and transports specific goods. The specific box body can be made according to the needs. The hoisting of the box body on the land generally uses a reach crane or an ordinary telescopic boom crane. The crane grabs the box body through the box arm and moves the box body Hoist the container onto the transport vehicle or stack the container; in large ports, gantry cranes or mobile cranes are generally used to lift the container between the wharf and the container freighter; The ship crane is used to lift the box body.

[0002] When transporting batches of goods, in order to ensure the safety of the transportation process and the convenience of transshipment, the goods are generally packed into boxes for transportation. For example, ocean shipping generally uses general-purpose boxes to transport goods, and transports specific goods. The specific box body can be made according to the needs. The hoisting of the box body on the land generally uses a reach crane or an ordinary telescopic boom crane. The crane grabs the box body through the box arm and moves the box body Hoist the container onto the transport vehicle or stack the container; in large ports, gantry cranes or mobile cranes are generally used to lift the container between the wharf and the container freighter; The ship crane is used to lift the box body. When using the ship crane to lift the box body, first use two steel wire ropes with hooks at both ends to hook the box corners of the box body, and then hang the steel wire ropes on the hooks of the crane. This lifting method seems simple, but there is a danger of the hook coming out of the corner of the box. In addition, because the box has no rigid limit, the box will shake or swing due to the effect of wind when the box is hoisted. When operating on a ship, the shaking will be greater. This lifting method requires manual pulling and guiding of the box when lifting and lowering the box, which will increase the manual workload and make the guidance of the box People are in a dangerous situation for a long time; in order to overcome the defects of the flexible connection of the wire rope, there are also cases where the box is hoisted by a fully rigid connection, but if a rigid connection is used, the alignment between the hanger and the box is difficult to be accurate and needs to be adjusted continuously Hanger location, very inefficient
