The winding plant of the two group fixed pulley groups of band
Technical field
The utility model relates to a kind of winding plant, is specifically related to a kind of winding plant with two group fixed pulley groups.
Background technology
At present, the winding plant that in weight-lifting equipment, uses, form lifting appliance jointly by linking together with pulley gear, this device has improved work efficiency to a certain extent, but because its limitation, general winding plant just has one group of fixed pulley group, and is bigger for weight like this, when perhaps the object that will lift by crane is many, will lower work efficiency.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of rational in infrastructure, and is easy to operate, the winding plant of the two group fixed pulley groups of the band that can increase work efficiency.
The utility model be achieved in that comprise motor and with motor bonded assembly drop-gear box, the mouth of drop-gear box is by being installed in the corresponding connection with the left and right tooth wheel transmission device of left and right sides transmission shaft on the fixed mount of the left and right sides, and this gear system is connected with belt pulley in the fixed pulley group by belt.
Described fixed pulley group is provided with balance wheel.
Described balance wheel is provided with limit switch.
Described drop-gear box is provided with lubricating system.
The utlity model has following advantage: the utility model is owing to added one group of fixed pulley, and structurally more reasonable, it is also very convenient to operate, and has improved the efficient of work to a great extent.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprise motor 1 and with motor 1 bonded assembly drop-gear box 2, the mouth of drop-gear box 2 is by being installed in the left and right sides transmission shaft 7 and the 6 corresponding connections of left and right tooth wheel transmission device on the left and right sides fixed mount 8, and this gear system 6 is connected with belt pulley 10 in the fixed pulley group 3 by belt.
Described fixed pulley group 3 is provided with balance wheel 4.
Described balance wheel 4 is provided with limit switch 5.
Described drop-gear box is provided with lubricating system 9.
