Embodiment Construction

[0018] The present invention is further described below in conjunction with accompanying drawing:

[0019] see figure 1 , a manual hydraulic multi-point synchronization mechanism, including a first handle 11, a second handle 21, a hand pump, a shuttle valve 3 and a hydraulic cylinder 12; the first handle 11 and the second handle 21 are connected with a hand pump, and the two The pistons 121 in each hand pump are connected to the shuttle valve 3, and the shuttle valve 3 is connected to the hydraulic cylinder 12;

[0020] The hand pump includes several pistons 121, and the piston rod of each piston is hinged to the ends of the first handle 11 and the second handle 21 respectively.

[0021] The number of pistons is three, and the ends of the pistons are connected to the shuttle valve 3 through hydraulic hoses, and the shuttle valve 3 is connected to the hydraulic cylinder 12 through hydraulic hoses 6 .

[0022] A joint 9 is installed on the hydraulic hose between the shuttle va...

Abstract

A manual hydraulic multi-point synchronization mechanism and its operation method, including a first handle, a second handle, a hand pump, a shuttle valve and a hydraulic cylinder; the first handle and the second handle are connected with a hand pump, and the two hand pumps The pumps are all connected to the shuttle valve, and the shuttle valve is connected to the hydraulic cylinder; it solves the problem that when the helicopter multi-point hanging release system releases cargo in the air, it can drive multiple cargo hooks to release simultaneously without being damaged due to the swing of the cargo hook with the helicopter key technical issues.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pressure, and in particular relates to a manual hydraulic multi-point synchronization mechanism and an operation method thereof. Background technique [0002] At present, the air delivery system of domestic helicopter transportation hanging goods is developing towards the direction of three-point or multi-point hanging. For the multi-point hanging delivery system, when the goods are delivered in the air, when the electrical delivery fails, the manual emergency delivery mechanism is used to release the goods. During the helicopter hanging transportation, if three or more cargo hooks cannot be opened simultaneously, it will cause some cargoes to be released while some cargoes are suspended on the helicopter, causing the center of gravity of the helicopter to exceed the safe range, causing the The helicopter lost its balance and a major safety accident occurred. Therefore need a kind of not only c...
