Summary of the invention
In view of this, the present invention is intended to propose a kind of hoisting crane and base hook connecting device thereof, when approaching the over-the-road transportation maximum width to solve the base width, surpasses the problem that the over-the-road transportation maximum width requires because of stretching out of hook causes base transportation width.
For achieving the above object, technical scheme of the present invention is achieved in that
On the one hand; The invention provides a kind of base hook connecting device; Comprise the connecting element that is arranged on the said base, with said connecting element bonded assembly hangers and be connected the counterweight pallet on the said hangers; Said connecting element comprises the free bearing that is arranged on said base top, and said hangers is that first end and said free bearing are hinged, second end extends downward the attaching parts of said chassis outer side by said base top, and said counterweight pallet is connected with second end of said hangers.
Further, said connecting element comprises also and is arranged on said chassis outer side and towards the hook of upper shed, second end of said hangers also is provided with the link plate with said hook corresponding matching that second end of said hangers hangs on the said hook through said link plate.
Further, said counterweight pallet detouchable is connected on second end of said hangers, and said detouchable is connected to hinged or bolted connection.
Further, said counterweight pallet is non-removable to be connected on second end of said hangers, said non-removable be connected to welding or riveted joint.
Further; Said hangers comprises two blocks of L shaped steel plates that laterally arrange and is connected the connecting panel between these two blocks of L shaped steel plates; Said link plate is also for being connected the platy structure between said two blocks of L shaped steel plates; And first end at said two blocks of L shaped steel plates is provided with and cooresponding first mounting hole of said free bearing, is provided with and counterweight pallet bonded assembly second mounting hole at second end of said two blocks of L shaped steel plates.
Further, said link plate is provided with and said link plate and the vertical reinforcement gusset of said L shaped steel plate with the outside of said L shaped steel plate.
On the other hand, the present invention also provides a kind of hoisting crane that is provided with above-mentioned base hook connecting device.
With respect to prior art; The present invention has following advantage: base hook connecting device of the present invention and base are the detouchable relations; Through change to base hook connection mode, can make the base hook can satisfy fixing central counterweight pallet and the not ultra wide requirement of base transportation, and when transportation; Hangers can transport separately, also can with the transportation that links together of counterweight pallet.
