Specific implementation mode
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the claims and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
Refering to fig. 1-4, it is a kind of shield machine segment unloader described in the utility model, including bottom bracket 1 and symmetrical
At least a pair of of unloading unit (illustrating a unloading unit in figure) set on 1 both sides of the bottom bracket.Each unloading unit
Including master arm 2, oil cylinder 3, auxiliary support arm 4 and section of jurisdiction bracket 5,
One end of master arm 2 is hinged by first axle 61 and bottom bracket 1, and the other end is held in the palm by the second axis 62 with section of jurisdiction
Frame 5 is hinged；Auxiliary support arm one end is hinged by third axis 63 and bottom bracket 1, and the other end is held in the palm by the 4th axis 64 with section of jurisdiction
Frame 5 is hinged.Preferably, the distance between the distance between first axle 61 and third axis 63 and the second axis 62 and the 4th axis 64 phase
Together.In this way, bottom bracket 1, master arm 2, section of jurisdiction bracket 5 and auxiliary support arm 4 form four-bar mechanism.
One end of oil cylinder 3 is hinged by the 5th axis 65 and bottom bracket 1, and the other end passes through the 6th axis 66 and the main support
Arm 3 is hinged.Preferably, the 5th axis 65 is located at third axis 63 in the side of first axle 61, and the 6th axis 66 is located at master arm
2 in a part for section of jurisdiction bracket 5.In this way, oil cylinder and master arm form toggle.
In addition, for the ease of hinged, it is convex that first lug 11, the second lug 12 and third are respectively set on bottom bracket 1
The 4th lug 21 is arranged on the master arm 2 for ear 13, and wherein first axle 61 is arranged in first lug 11, and third axis 63 is set
It sets on the second lug 12, the 5th axis 65 is arranged on third lug 13, and the 6th axis is arranged on the 4th lug.
The tricks of the above-mentioned unloading unit of the shield machine segment unloader is adjusted according to the quantity of section of jurisdiction.In off working state
Under, oil cylinder 3 is in retracted mode, and section of jurisdiction bracket 5 is in low level；Section of jurisdiction is transported to 5 top of section of jurisdiction bracket when servicing train,
When needing to unload section of jurisdiction, oil cylinder 3 stretches out, and master arm 2 is pushed to be rotated around first axle 61, and then drives section of jurisdiction bracket 5 and auxiliary
4 position of support arm increases, and section of jurisdiction is lifted from service train, service train can sail out of；Conduct oneself with dignity by section of jurisdiction, oil cylinder 3 is retracted
To original state, the unloaded operation of section of jurisdiction is completed.
It can be seen that the shield machine segment unloader is by hydraulic oil cylinder driving toggle and four-bar mechanism, with band
Dynamic section of jurisdiction bracket lifting, carries out the unloading of section of jurisdiction, is not only simple in structure, and has the advantages that dependable performance, failure rate are low etc., together
When can greatly improve service train service efficiency, can be widely used in shield machine technical field of engineering machinery.
