Problems solved by technology
Most of the time, the containers are stacked so high that the operator cannot directly observe the holes on the upper surface of the container, so there is a lot of blindness in the hole operation, which not only wastes time, but also often causes collisions, which makes the spreader structure prone to advance failure phenomenon

Embodiment 1
[0024] In the present invention, the spreader mechanism applicable to container transfer, such as image 3 As shown, it includes an L-shaped hook 1 and a rectangular groove 11. The L-shaped hook 1 is symmetrically arranged at the four corners of the spreader base plate 2. The spreader base plate 2 is provided with a through hole that is connected with the connecting rod. Tool bottom plate 2 is all provided with the through hole that cooperates with it in L-shaped suspension hook 1 sliding section. The rectangular groove 11 is arranged on both sides of the container, and the L-shaped hook 1 is provided with a through hole to cooperate with the tie rod 3, and the tie rod 3 is connected to the oil cylinder 7 through the flange plate 4 and the threaded fastener 5 , the pull rod 3 can move bidirectionally on the bar-shaped sliding surface 8 through the expansion and contraction of the oil cylinder 7, the flange plate 4 is welded on one end of the pull rod 3, and the hinge seat 6 of...

The invention discloses a lifting tool for transferring packing boxes. The lifting tool comprises a lifting tool bottom plate (2) and four lifting hooks. The lifting tool bottom plate (2) is rectangular, the four lifting hooks are located below the lifting tool bottom plate (2), and projections of the four lifting hooks on the lifting tool bottom plate (2) are distributed at the four corners of the rectangle of the lifting tool bottom plate (2). The lifting hooks are driven by an oil cylinder (7). The oil cylinder (7) is connected with a pull rod (3) and used for driving the pull rod (3) to move. The pull rod (3) is connected with the lifting hooks and used for driving the lifting hooks to move. The oil cylinder (7) and the pull rod (3) are both located above the lifting tool bottom plate (2). Holes are formed in the four corners of the lifting tool bottom plate (2), and the lifting hooks are connected with the pull rod (3) through the holes. The lifting tool can be well matched with the packing boxes, the interval change of the lifting hooks can meet the use requirements of the packing boxes, and high safety is achieved.
Description
technical field [0001] The invention belongs to the field of hoisting machinery design, and more specifically relates to a spreader used for container transfer, especially suitable for lifting operations such as lifting and transfer of containers in industries such as machinery, chemical industry, port, ship and sea. Background technique [0002] As we all know, the use of containers to transfer bulk materials is an essential and important way. As an international standard container, the structure of the spreader is relatively mature, and a rigid structure with both telescopic and slewing is generally used, usually as figure 1 As shown, that is, a cylindrical lock head is connected to the turn lock placed on the bottom plate of the spreader, and the turn lock is connected to the power device through an intermediate mechanism. The four corners of the upper panel of the container are provided with rectangular through holes, and the length of the lock head is larger than that o...
