Abstract
The utility model discloses a kind of sensor construction be applied in the test of tower machine weight, it is characterized in that, be provided with the first fixed pulley, described first fixed pulley is connected with balance rope, hoisting rope and rope rolling; Described first fixed pulley is connected with sensor by cable wire; Described sensor body is fixed on a support, and one end is provided with deformation spring; Described hoisting rope one end connects the first fixed pulley, and has connected weight via the second fixed pulley, the 3rd fixed pulley.This structure effectively calculates tower crane lifting weight by a kind of method that installs and measures newly, namely utilizes installation position displacement sensor, measures the deformation quantity in cable wire, indirectly draws lifting weight.
Description
Technical field:
The utility model relates to a kind of sensor construction be applied in the test of tower machine weight.
Background technology:
The scheme of existing measurement tower crane lifting weight has a lot, and the most frequently used scheme utilizes wire ropes for tower cranes inner at tower body, with tower body tower joint fixed weight sensor, measures steel wire rope tension.And the program is combined sensor, be connected with pulley (dead sheave); When tower machine runs, steel rope is stressed gives pulley pressure, thus measures the gravity that tower machine pulls.Also there is following defect in the program:
1) because its mounting structure is complicated, different tower machine when mounted a angle is difficult to fix, therefore does not have universality during tower machine for different model.
2) because it is mounted on the cross bar that stress comparatively concentrates, when this is in lifting, very easily produce deformation, make the fixing difficulty of installation.
3) program indirectly calculates lifting weight according to rope angulation a, but because of angle a too small, cause the extremely small change of a all can cause the inaccurate of result of a measurement, error is larger.
Utility model content:
In view of above-mentioned technical matters, the utility model provides a kind of sensor construction be applied in the test of tower machine weight, this structure effectively calculates tower crane lifting weight by a kind of method that installs and measures newly, namely installation position displacement sensor is utilized, measure the deformation quantity in cable wire, indirectly draw lifting weight.
Concrete technical scheme of the present utility model is as follows:
Be applied in the sensor construction in the test of tower machine weight, it is characterized in that, be provided with the first fixed pulley, described first fixed pulley is connected with balance rope, hoisting rope and rope rolling; Described first fixed pulley is connected with sensor by cable wire; Described sensor body is fixed on a support, and one end is provided with deformation spring; Described hoisting rope one end connects the first fixed pulley, and has connected weight via the second fixed pulley, the 3rd fixed pulley.
In such scheme, described sensor is displacement pickup.
The beneficial effects of the utility model are as follows:
1. structure is simple, is easy to install.
2., for different tower machine class, only need find out coefficient k and the b of its correspondence, there is good comformability.
3. error reduces greatly.
Accompanying drawing illustrates:
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, the sensor construction be applied in the test of tower machine weight described in the utility model.It is provided with the first fixed pulley 1, and this first fixed pulley connects 1 and is connected to balance rope 2, hoisting rope 3 and rope rolling 4; Described first fixed pulley 1 is connected with sensor 6 by cable wire 5.This sensor 6 is displacement pickup, and its sensor 6 body is fixed on a support 7, and one end is provided with deformation spring 8.In addition, hoisting rope 3 one end connects the first fixed pulley 1, and takes turns via the second fixed pulley 9, the 3rd surely sliding 10 and connected weight 11.
Structure according to technique scheme, when tower machine is at hoisting heavy, cable wire is one of its Main Load supporting region, there is more significant linear relationship between its deformation quantity and weight, therefore only need detect deformation wherein, and founding mathematical models.
1) foundation of math modeling:
Due to the material behavior of cable wire, it is stressed roughly follows Hook's law with deformation, therefore can Modling model
F＝kx+b
Find out proportionality coefficient k corresponding to different tower machine and coefficient of correction b again and can draw weight.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
