Further, the lifting assembly comprises a lifting arm and a lifting oil cylinder; the lifting oil cylinder is positioned below the lifting arm, the lifting arm and the lower end of the lifting oil cylinder are hinged with the transportation trolley, and the other end of the lifting oil cylinder is hinged with the lifting arm; the chain is arranged at the upper end of the lifting arm.
Further, the two transport trolleys are provided with lug plates, and two ends of the baffle rod are connected to the two transport trolleys through pin shaft lug plates.
Further, the lower parts of the frames of the two transport trolleys are respectively connected with a bogie through turntable bearings in a rotating mode, and wheel pair assemblies are respectively arranged below the bogies.
Further, two chains are arranged on each lifting arm.
Further, the end parts of the two transport trolleys, which are far away from each other, are provided with connectors.
Further, the lifting oil cylinder is positioned at one side of the lifting arm close to the lifting space.
Further, two ends of the connecting beam are welded and fixed on the two transport trolleys respectively.
The utility model has the beneficial effects that: the hydraulic support is placed into the hoisting space from the side surface during transportation, the other side is fixedly connected by the pin shaft through the baffle rod, and the hydraulic support is hoisted by the chain.

Detailed Description
The technical solution of the present utility model will be further described with reference to fig. 1 to 3 and examples, so that those skilled in the art can more clearly understand the content of the technical solution.
The embodiment of the low roadway hydraulic support conveying device comprises two conveying trolleys 1 positioned at the front part and the rear part; the ends of the two transport trolleys 1, which are far away from each other, are provided with connectors 8. The front side and the rear side of the two transport trolleys 1 are respectively provided with a connecting beam 4 and a baffle rod 12; the two ends of the connecting beam 4 are respectively welded and fixed on the two travelling trolleys 1. The two transport trolleys 1 are respectively provided with an ear plate, and two ends of the baffle rod 7 are connected to the two transport trolleys 1 through pin shaft ear plates. A hoisting space for placing the hydraulic support 3 is formed among the connecting beam 4, the baffle rod 7 and the two transport trolleys 1; lifting assemblies are arranged on the two transport trolleys 1, chains 6 are arranged on the lifting assemblies, and the other ends of the chains 6 are connected with the hydraulic supports 3.
The lifting assembly comprises a lifting arm 2 and a lifting oil cylinder 5; the lifting oil cylinder 5 is positioned below the lifting arm 2, the lifting arm 2 and the lower end of the lifting oil cylinder 5 are hinged with the transportation trolley 1, and the other end of the lifting oil cylinder 5 is hinged with the lifting arm 2; the chain is arranged at the upper end of the lifting arm 2. The lifting oil cylinder 5 is positioned at one side of the lifting arm 2 close to the lifting space. Two chains 6 are arranged on each lifting arm 2, and four chains are respectively connected with four corners of the hydraulic support. When the lifting cylinder stretches out or shortens, the hydraulic support can be lifted or lowered.
The lower parts of the frames of the two transport trolleys 1 are respectively connected with a bogie 11 in a rotating way through a turntable bearing 10, and wheel pair assemblies 9 are respectively arranged below the bogies 11. The bogie and wheel set assembly herein may take the form of a structure within a bogie steering mechanism as is commonly used in the art.
In this embodiment, in the advancing process of transportation, lift the hydraulic support through two lifting arms through "lift sedan-chair" mode, adopt the mode of middle part open crotch can furthest reduce the transport height, even transport the part and can wipe the track transportation, can reduce the transport height to the limit, the effect is very obvious. The transport device in this embodiment can be lowered by at least 300mm in transport height.
