Abstract
The utility model discloses a gram makes trapeze rod -type measuring force device, including the body of the tower body, still included and risen pulley and fixed pulley, it is equipped with wire rope to rise between pulley and the fixed pulley, fixed pulley passes through the lever mechanism and links to each other with the body of the tower body, still include the force transducer continuous with the lever mechanism who locates on the body of the tower body. The utility model discloses wire rope the time applys power on fixed pulley holding the loading lotus, through lever plate's leverage, converts power to single direction's pressure, applys on force transducer. The size that be stressed is obtained by the signal of telecommunication of force transducer output to calculate the power that receives on the fixed pulley, calculate the power of bearing from this on the wire rope, thereby can obtain the loop wheel machine magnitude of load. The utility model discloses simple structure, it is accurate to measure, and the error is little, and the commonality is strong, and debugging and maintenance are convenient, have reduced the degree of difficulty that the control program was compile.
Description
Technical field
The utility model relates to a kind of crane lever device for measuring force, belongs to mechanical equipment technical field.
Background technology
When the multiplying power that hoists of existing crane is 3 according to the applicant understood, generally there are 3 kinds of dynamometry modes.One, stress sensor in hydraulic circuit.Two, motor output shaft adds torque sensor.Three, tower body head lifting pulley axle adds force snesor.
Above-mentioned three kinds of common at present methods, method one, requires higher to hydraulic circuit, and can not be applied to electric crane.Method two, layout and installation and subsequent maintenance inconvenience.Method three, because the cornerite angle of steel rope on lifting pulley changes greatly, need add two place's strain-gaugies in the horizontal and vertical directions, not only error is large, and brings very large difficulty to follow-up debugging and writing of program.
Utility model content
The purpose of this utility model is: for above-mentioned prior art Problems existing, proposes a kind of crane lever device for measuring force.
In order to reach above object, a kind of crane lever device for measuring force, comprises tower body body; It is characterized in that: also comprise lifting pulley and dead sheave; Steel rope is provided with between described lifting pulley and dead sheave; Described dead sheave is connected with tower body body by leverage; Also comprise the force snesor be connected with leverage be located on tower body body.
Further, described leverage comprises the lever plate of shape in obtuse angle.
Further, described lever plate has three point of connection, and described three point of connection are connected with dead sheave, tower body body and force snesor respectively.
Further, described force snesor is connected with the point of connection of lever plate by pressure cushion block.
Power is applied on dead sheave when bearing load by the utility model steel rope, by the leverage of lever plate, power is converted to the pressure of single direction, is applied on force snesor.The electric signal exported by force snesor obtains the size of pressure, thus calculates the power that dead sheave is subject to, and calculates the power that steel rope bears thus, thus can obtain loop wheel machine magnitude of load.The utility model structure is simple, and measure accurately, error is little, highly versatile, debugging and easy to maintenance, reduces the difficulty that control program is write.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1-steel rope; 2-lifting pulley; 3-dead sheave; 4-lever plate; 5-pressure cushion block; 6-force snesor; 7-tower body body.
Detailed description of the invention
As shown in Figure 1, a kind of crane lever device for measuring force, comprises tower body body 7; Also comprise lifting pulley 2 and dead sheave 3; Steel rope 1 is provided with between described lifting pulley 2 and dead sheave 3; Described dead sheave 3 is connected with tower body body 7 by leverage; Also comprise the force snesor 6 be connected with leverage be located on tower body body 7.
Leverage described in the utility model comprises the lever plate 4 of shape in obtuse angle.Described lever plate 4 has three point of connection, and described three point of connection are connected with dead sheave 3, tower body body 7 and force snesor 6 respectively.Described force snesor 6 is connected with the point of connection of lever plate 4 by pressure cushion block 5.
Power is applied on dead sheave when bearing load by the utility model steel rope, by the leverage of lever plate, power is converted to the pressure of single direction, is applied on force snesor.The electric signal exported by force snesor obtains the size of pressure, thus calculates the power that dead sheave is subject to, and calculates the power that steel rope bears thus, thus can obtain loop wheel machine magnitude of load.The utility model structure is simple, and measure accurately, error is little, highly versatile, debugging and easy to maintenance, reduces the difficulty that control program is write.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
