The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the crane span structure of hoisting crane is by the end at two parallel girders 6 end carriage 5 to be installed respectively to be constituted, and trolley track 2 all is housed on each girder 6, and carriage device 1 is installed on the trolley track 2.The concrete formation of carriage device 1 is, please refer to Fig. 3 and Fig. 4, parallel installation two cover dolly jack up units on the trolley frame 1-11 that places on the trolley track 2, the concrete structure of dolly jack up unit is, reel 1-4 is installed on trolley frame 1-11, the retarder 1-3 that hoists is housed on reel 1-4, on the retarder 1-3 that hoists, lifting motor 1-2 is housed, hoist brake 1-1 is housed on lifting motor 1-2; On reel 1-4, also be wound with steel rope 1-5, on steel rope 1-5, mounted suspension hook 1-6.
Connect above-mentioned, wheeling mechanism also is installed on trolley frame 1-11, the concrete structure of wheeling mechanism is, parallel installation two cover drive cars on trolley frame 1-11, the concrete structure of drive car is, dolly retarder 1-10 is installed on trolley frame 1-11, vehicle motor 1-9 is installed on dolly retarder 1-10, car brake 1-8 is installed on vehicle motor 1-9.Set of wheels 1-12 all is housed on drive car, and frame is equipped with an adapter shaft 1-7 between set of wheels 1-12.
Connect above-mentioned, one cover cart actuating device all is housed on four terminations of crane span structure end carriage 5, and the concrete structure of cart actuating device is cart retarder 4 to be installed on the end carriage 5 of crane span structure, cargo motor 3 is installed on cart retarder 4, bigger vehicle brake 7 is installed on the cargo motor 3.
The utility model has three-dimensional motion, includes hoisting of the operation of cart device and carriage device operation and dolly jack up unit.It drives the complete machine operation by cargo motor 3 by cart retarder 4.
