The transmission design is simple and direct, so that the lifting device is widely applied to occasions such as factories, warehouse, wharfs, power stations, logging yards and the like, and is good lifting equipment for lifting and carrying articles.
However, the above-mentioned hoisting device has a great disadvantage that since the brake of the motor with the brake is mounted at the tail end of the motor, the motor shaft frequently rotates forwards and backwards, the motor shaft is easily damaged due to fatigue and easily fails in a life cycle, and once the spline part at the front end of the motor fails, the brake at the tail end of the motor loses the braking capability, so that the hoisting device is out of control, heavy objects fall freely, and great danger is caused to life and property.
[ Utility model ] content
The utility model aims at providing a braking safe and reliable and be convenient for maintain wire rope electric block's hoist device to the not enough of above-mentioned prior art.
Therefore, the utility model adopts the following technical scheme:
the utility model provides a hoisting device of wire rope electric block, including left branch strut wallboard, right branch strut wallboard, be located the reel between left branch strut wallboard and the right branch strut wallboard, be located the middle transmission shaft of reel, the wire rope of winding on the reel, fix two unification brake motors on right branch strut wallboard and be fixed in the reducing gear box of left branch strut wallboard and being located the reel, the right-hand member of middle transmission shaft links to each other through its output shaft of first shaft coupling and two unification brake motors, the left end of middle transmission shaft passes through the second shaft coupling and links to each other with its input shaft right-hand member of reducing gear box, the box of reducing gear box and the hookup of the transmission cover spline that is fixed in the reel inner wall, its improvement point is outside its input shaft left end of reducing gear box wears out left branch.
Compared with the prior art, the utility model discloses following beneficial effect has:
the opposite end (left end) of the input shaft of the reduction gearbox for the connecting end of the second coupling is additionally provided with the plane brake, and under the working condition that the output shaft of the two-in-one brake motor is frequently rotated forwards and backwards, when the brake of the two-in-one brake motor fails, the plane brake can brake the whole hoisting device, so that the serious consequence caused by out-of-control of the hoisting device is avoided, the life safety is ensured, and the property loss is avoided.
Because the external plane brake is positioned outside the supporting wallboard, the plane brake is convenient to disassemble and assemble without interference, is convenient to maintain and work, avoids impurities such as lubricant and the like from polluting the working surface of the plane brake, and ensures the braking performance.
