[0004] 2. The current quick unloading principle basically relies on gravity, so it can only unload in the vertical direction, and it is powerless for quick unloading of large loads in horizontal or other directions;
[0005] 3. The current unloading operations all have disadvantages such as cumbersome process and high cost. They are only suitable for specific workplaces, and the promotion value is not high. Coupled with the influence of human factors, the safety cannot be guaranteed.

Embodiment 1

[0030] Reference attached Figure 1~4 : The multi-stage load reduction and quick-discharge device includes a lifting device for hooking and lifting goods and supporting plates 3 on both sides. One end of the supporting plates 3 on both sides is connected in series by the front fixing pin 2 and the other end is connected by the rear fixing pin. 8 are connected in series, and the rear fixing pin 8 is sleeved with a shaft sleeve 9 that separates and positions the supporting plates 3 on both sides. One end of the lifting device is a hook 1, and the other end is a connecting rod 5 integrated with the hook 1. The lifting device is rotatably installed in the housing composed of the support plates 3 on both sides through the front fixing pin 2, and the hook 1 extends On the housing, one side of the lifting device is equipped with a three-stage load reduction mechanism that can lock the connecting rod 5 to prevent the lifting device from rotating. The fixed ends of the three-stage load ...

Abstract

The invention relates to a multistage load-reducing quick unloading device, belonging to the field of cargo loading and unloading equipment. The multistage load-reducing quick unloading device comprises a lifting device for lifting cargoes and is characterized in that a hook (1) is arranged at one end of the lifting device, a connecting rod (5) which is integrally connected with the hook (1) is arranged at the other end of the lifting device, the lifting device is rotatably installed in a shell consisting of two supporting plates (3) through a front fixing pin (2), the hook (1) stretches out of the shell, a multistage load reducing mechanism which tightly presses the connecting rod (5) to prevent the lifting device from rotating is installed on one side of the lifting device, the fixed end of the multistage load reducing mechanism is fixedly arranged in the supporting plates (3) on the two sides, and a pull pin (6) which is used for breaking the balance of the multistage load reducing mechanism is arranged on one side of the movable end of the multistage load reducing mechanism. The multistage load-reducing quick unloading device has the advantages that the structure is simple, the device is convenient to operate and the quick and safe unloading of large loads in any direction can be realized through multistage load reduction.

Description

Technical field [0001] A multi-stage load-reducing and quick-unloading device belongs to the field of cargo handling equipment, and specifically relates to a large-load quick-unloading device capable of multi-stage load reduction. Background technique [0002] At present, the rapid unloading technology of large loads has been widely used in many fields such as port hoisting, construction and military industry. The existing technical solutions basically use gravity, which mainly has the following shortcomings: [0003] 1. The current large-load unloading device has a relatively complicated structure and relies too much on operator experience. Before unloading, manual adjustment and cooperation are required, and the unloading device is usually rotated to a specific position first; [0004] 2. The current principle of quick unloading basically relies on gravity, so it can only realize unloading in the vertical direction, and it is powerless for the rapid unloading of large loads in hor...
