Abstract
The utility model discloses a crane power takeoff device with a swinging pulley. The crane power takeoff device comprises a pulley base which is fixedly connected with a hoisting end of a crane boom; a swinging pulley is arranged at the lower end of the pulley base and comprises a pulley bracket and a pulley body; the pulley body is connected with the pulley bracket through a pin shaft sensor; the pin shaft sensor is electrically connected with an electric control system of the crane. According to the crane power takeoff device, the swinging pulley with the pin shaft sensor is adopted, the pulley is wound with a steel wire rope and is used for pulling and hoisting, the steel wire rope is pulled during hoisting, the tension is converted into pressure of the pulley, the pressure of the pulley totally acts on the pin shaft, and then the force is converted into an electric signal to be transmitted back to the electric control system of the crane. Compared with a three-pulley power takeoff mode in the prior art, the crane power takeoff device is simple in structure and is safe, effective and accurate in power takeoff; and the cost is reduced by about 80 percent.
Description
Technical field
The utility model relates to elevator machinery technical field, is specifically related to a kind of hoisting crane power takeoff with swinging pulley.
Background technology
Tape guide pulley lift is mainly used in heavy industry and manufacturing, port machine manufacturing etc.The general lift heavy of this hoisting crane is larger, generally uses many steel ropes and pulley to realize while hoisting as far as possible laborsaving.In order to obtain steel rope actual load, need set up special-purpose taking power apparatus at above-mentioned hoisting crane, to guarantee the safe handling of hoisting crane.
The power taking mode of the craning weight of same load three pulley power taking modes that adopt in prior art: three pulleys are installed in hoist rope both sides more, utilizing lift heavy is that the lateral pressure of the stressed generation of steel rope makes pressure sensor generation elastic deformation, there is following defect in this mode: complex structure, and cost is high; Pulley in steel rope and power takeoff rubs, and affects the efficiency of lifting mechanism; Steel rope is easy to wear, has certain potential safety hazard; Acquisition of signal mode is not direct, the bigger error of measured data.In improved technical scheme, pulling force sensor is arranged on to hoist rope end, when running into lift heavy overbalance in crane hook fast lifting or affected by external force, easily causes the phenomenon of wirerope-winding.Therefore, be necessary the power takeoff of existing hoisting crane to carry out structural development.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of hoisting crane power takeoff with swinging pulley is provided, and this apparatus structure is simple, and power taking is safe and effective and more accurate, and cost is lower.
For achieving the above object, the technical solution of the utility model is: a kind of hoisting crane power takeoff with swinging pulley, it is characterized in that, described hoisting crane power takeoff comprises the pulley base being fixedly connected with crane arm support lift heavy end, the lower end of described pulley base is provided with swing pulley, described swing pulley comprises pulley bracket and pulley body, and described pulley body is connected with pulley bracket by bearing pin sensor, and described bearing pin sensor and crane electric control system are electrically connected.
In order to show more intuitively steel rope actual load, preferred technical scheme is that described bearing pin sensor and load telltale are electrically connected.
Advantage of the present utility model and beneficial effect are:
This hoisting crane power takeoff adopts the swing pulley with bearing pin sensor, pulley lay winding wire ropes is used for pulling lift heavy, steel rope tension during lift heavy, and pulling force is converted to the pressure of pulley, the pressure of pulley all acts on bearing pin, and now power is converted to electric signal and sends back crane electric control system.Compare with three pulley power taking modes of the prior art, simple in structure, power taking is safe and effective and more accurate, and cost declines approximately 80%.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model hoisting crane power takeoff;
Fig. 2 is the use constitution diagram of the utility model hoisting crane power takeoff;
In figure: 1, pulley base; 2, pulley bracket; 3, pulley body; 4, bearing pin sensor; 5, hoisting crane power takeoff.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, embodiment is a kind of hoisting crane power takeoff 5 with swinging pulley, hoisting crane power takeoff 5 comprises the pulley base 1 being fixedly connected with crane arm support lift heavy end, the lower end of pulley base 1 is provided with swing pulley, swing pulley and comprise pulley bracket 2 and pulley body 3, pulley body 3 is connected with pulley bracket 2 by bearing pin sensor 4, and bearing pin sensor 4 is electrically connected with crane electric control system.
In the present embodiment, bearing pin sensor 4 is electrically connected with load telltale.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
