Description
Technical field
The utility model relates to a kind of mechanism that promotes weight, particularly relates to a kind of manual puffer.
Background technology
Winch mainly applies to build, the material of hydraulic engineering, forestry, mine and harbour etc. goes up and down or flat dragging.At present, common puffer all need drive through HM Hydraulic Motor when promoting weight, not only wastes electric power, and complicated operation, and fault rate is high.Just do not have under the situation of propulsion source can't, thereby restricted production.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, easy to operate manual puffer.
In order to address the above problem, the utility model adopts following technical scheme:
Manual puffer; Comprise casing, worm screw, worm gear, transmission shaft, bearing seat, cylinder and crank, installation worm and worm gear in the casing, worm screw is connected with turbo drive; The casing outside is provided with crank; Crank is connected with worm screw, and transmission shaft is fixed together through positioning key and turbine and cylinder respectively, and cylinder one side is provided with bearing seat; Transmission shaft one end is installed on the casing, and an end is installed on the bearing seat.
Bearing is installed at described transmission shaft two ends respectively, is connected through bearing respectively between transmission shaft and casing and the bearing seat.
Bearing is installed at described worm screw two ends, is connected through bearing between worm screw two ends and the casing.
Described cylinder is provided with pressing plate, and pressing plate is through being bolted on the cylinder.
Compared with prior art, the beneficial effect of the utility model is:
The utility model reasonable in design, easy to operate, in that do not have under the situation of propulsion source also can manual operation, thereby enlarged range of use, saved the energy.
