Abstract
The utility model discloses a roll change lift dolly, including the frame, lift platform, set up elevating system on the frame, elevating system includes connecting seat no. 1 and connecting seat no. 2 with lift platform fixed connection, connection piece no. 1, connection piece no. 2, the one end of connection piece no. 1 and connecting seat are one articulated, and the middle part of connection piece no. 1 articulates on the frame, and the one end of splicing no. 2 and connecting seat are two articulated, and the middle part of connection piece no. 2 articulates on the frame, the conduction pole, the other end of connection piece no. 1 and the other end of connection piece no. 2 are connected respectively to the both ends of conduction pole, conduct the piece, conduct two fixed connection of one end and connection piece of piece, the cylinder is fixed on the frame, and including the piston rod, the other end that stretches out the end with conduct the piece of piston rod is articulated, and same space changes the connecting rod form into, because the each point is the pin joint, even the roll focus is skew a lot, also can go up and down freely.
Description
Technical field
The utility model relates to a kind of roll change lift cart.
Background technology
Roller mill easily damages at work with the roller being unified into milling train, and therefore roll often needs to change, and existing work roll cooling roll changing carriage is changed.
As shown in Figure 1, the original elevating mechanism of roll changing carriage is guide colume type, air cylinder driven, and guide pillar slides up and down along guide pin bushing, because space limit, guide pin bushing limited length, because roll center of gravity is amesiality during roll change, the stressed of guide pillar can be partial to roll center of gravity side, guide pillar can amesialityly cause guide pillar and guide pin bushing one side-friction force to increase, guide pillar is easy to and guide pin bushing generation jam in lifting process, can not realize any lifting, even have stuck phenomenon.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of roll change lift cart, and lifting freely.
For achieving the above object, the utility model provides following technical scheme: a kind of roll change lift cart, comprises vehicle frame, hoistable platform, and described vehicle frame arranges elevating mechanism, and described elevating mechanism comprises the Connection Block one and Connection Block two that are fixedly connected with hoistable platform;
Brace one, brace two, one end and the Connection Block one of brace one are hinged, and the middle part of brace one is hinged on vehicle frame, and one end and the Connection Block two of contact pin two are hinged, and the middle part of brace two is hinged on vehicle frame;
Conductive bar, the two ends of conductive bar connect the other end of brace one and the other end of brace two respectively;
Conductive sheet, one end of conductive sheet is fixedly connected with brace two;
Cylinder, is fixed on vehicle frame, comprises piston rod, the external part of piston rod and the other end of conductive sheet hinged.
Preferably, hoistable platform one end is provided with the hook part preventing roll from dropping.
Preferably, described hoistable platform is placed with directive wheel.
Preferably, described conductive sheet and brace two are bolted.
Preferably, described conductive sheet is welded with brace two.
By adopting technique scheme, arranging Connection Block one and Connection Block two is to ensure that hoistable platform keeps stable when moving up and down, by the mode that conductive sheet and brace two are fixed, only adopt a cylinder just can complete the synchronization lifting of Connection Block one and Connection Block two, efficiency is higher, synchronism is good, more stable lifting; Same space, changes connecting rod form into, because each point is pin joint, even if roll deviation of gravity center is a lot, also can be elevated freely.
