Problems solved by technology
[0004] Regarding the above-mentioned related technologies, the inventor believes that: when the electric hoist chain is rewound, due to the longer length of the reel, the same length of the chain on the reel Winding at the position of the reel, the other positions on the reel have less chain winding, which makes the reel vulnerable to uneven force and damage, resulting in a shorter service life of the reel

Embodiment Construction
[0034] The following is attached Figure 1-3 The application is described in further detail.
[0035]The embodiment of the present application discloses a double power driven electric hoist.
[0036] refer to figure 1 and figure 2 , the electric hoist includes a hoist housing 1, a walking trolley 2 fixedly connected to the housing 1, a reel 11 is rotatably connected in the housing 1, a chain 12 is wound on the reel 11, and the bottom wall of the housing 1 is an opening , for the chain 12 to slide down, and the lower end of the chain 12 is fixedly connected with a suspension hook 121 . Both ends of the reel 11 are coaxially connected with a rotating shaft 111, and the rotating shafts 111 are coaxially connected with a shaft coupling 13, a reducer 14, and a motor 15. The coupling 13 connects the reducer 14 and the reel 11 coaxially, and the motor 15 The output shaft is connected to the reducer 14, and the side of the motor 15 facing away from the reducer 14 is connected wit...

The invention relates to a dual-power drive type electric hoist which comprises a hoist shell and a walking trolley arranged on the shell. A winding drum is rotationally arranged in the shell, a chain is wound on the winding drum, a hinged column is arranged at one end of the bottom of the shell, a hinged plate is hinged to the lower end of the hinged column, a sliding block sliding in the length direction of the winding drum is slidably arranged on the hinged plate, the chain slidably penetrates through the hinged plate, a driving assembly driving the hinge plate to rotate away from one end of the hinged column is arranged on the shell, and the driving assembly is used for driving the hinged plate to rotate around the hinged column and then driving the sliding block to abut against the chain and slide. According to the dual-power drive type electric hoist provided by the invention, by arranging the hinged plate and the sliding block, the hinged plate is driven by the driving assembly to rotate, so that the sliding block exerts single-direction force on the chain when the winding drum winds or unwinds the chain, the chain is evenly wound on the winding drum and evenly unwound on the winding drum, the winding drum is evenly stressed, damage to the winding drum is reduced, and then the service life of the winding drum is prolonged.
Description
technical field [0001] The present application relates to the technical field of hoisting machinery, in particular to a dual-power driven electric hoist. Background technique [0002] At present, in warehouses, factories, docks, workshops, etc., electric hoists are mostly used for lifting and lifting, so as to transfer or transport heavy items in time, and electric hoists are a kind of lifting machinery that is common in most lifting operations. [0003] Related technology such as the announcement number CN101830406A discloses a new type of double power drive electric hoist for cranes. A set of motors, reducers and brakes with the same parameters are installed at both ends of the drum. On the control circuit, the two motors are connected to each other. Connected in parallel in the circuit, the two motors are controlled by the same control electromagnet, the same overcurrent relay and ammeter are connected to the branch of each motor, and the overcurrent relay in the branch o...
