Abstract
The utility model discloses a kind of overload rope-loosing protection device; described device comprises steel rope, cylindrically coiled spring, pressure sensor; the first end of described cylindrically coiled spring is connected with steel rope; second end is arranged on pressure sensor, and described pressure sensor is connected with controller by circuit.Overload rope-loosing protection device of the present utility model adopts cylindrically coiled spring, and this kind spring stress amplitude of deformation is comparatively large, can well touch electric elements proterctive equipment; In addition, the overload rope-loosing protection device after improvement also add steel rope pressure sensor, detects the pulling force of steel rope from system background, and when the numerical value that pressure sensor detects exceeds the value range of setting, equipment can send breakdown signal.
Description
Technical field
The utility model relates to a kind of safety guard, is specifically related to a kind of overload rope-loosing protection device of piler.
Background technology
Overload rope-loosing protection device is the fender guard controlling stacker loading platforms loading conditions, its effect is the pulling force size when bearing load on loading platform exceedes maximum permissible value by hoist rope, extension spring in tensile overload rope-loosing protection device produces different stroke, thus cut off lifting motor ring current or general supply, lifting mechanism is shut down thus proterctive equipment in time; When bearing load on loading platform is less than minimum permissible value by the pulling force size of hoist rope; spring in retraction overload rope-loosing protection device produces different stroke; thus cut off lifting motor ring current or general supply, lifting mechanism is shut down thus proterctive equipment in time.Traditional overload rope-loosing protection device controls by disk spring the different strokes that suffered by steel rope, different pulling force produces.Because belleville spring deflection is minimum, so there is very large defect in sensitivity.
Utility model content
For the problems referred to above, the purpose of this utility model be to provide a kind of highly sensitive, can proterctive equipment and the overload rope fender guard that can report to the police well.
The utility model is realized by following technical scheme:
A kind of overload rope-loosing protection device; described device comprises steel rope, cylindrically coiled spring, pressure sensor; the first end of described cylindrically coiled spring is connected with steel rope, and the second end is arranged on pressure sensor, and described pressure sensor is connected with controller by circuit.
Beneficial effect: traditional overload rope-loosing protection device controls by disk spring the different strokes that suffered by steel rope, different pulling force produces, because belleville spring deflection is minimum, so there is very large defect in sensitivity; And overload rope-loosing protection device of the present utility model adopts cylindrically coiled spring, this kind spring stress amplitude of deformation is comparatively large, well can touch electric elements proterctive equipment; In addition, the overload rope-loosing protection device after improvement also add steel rope pressure sensor, and when the numerical value that pressure sensor detects exceeds the value range of setting, equipment can send breakdown signal.
accompanying drawing illustrates:
Fig. 1 is the structural scheme of mechanism of the present embodiment.
Fig. 2 is the partial enlarged drawing of Fig. 1.
detailed description of the invention:
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
The two ends of loading platform are arranged on column, and loading platform is connected with steel rope, lifts by crane up-and-down movement by steel rope.Between steel rope and loading platform, be provided with an overload rope-loosing protection device, see Fig. 1, Fig. 2, a kind of overload rope-loosing protection device, comprises steel rope 1, cylindrically coiled spring 2, pressure sensor 3.Cylindrically coiled spring 2 first end is provided with a top cover 4, this top cover 4 links together with steel rope 1.In order to make cylindrically coiled spring 2 more firm, top cover 4 is also provided with a support 5, support 5 is provided with a through hole, this through hole is through top cover 4 and then be sleeved on top cover 4.This support 5 is fixed on loading platform again.Second end of cylindrically coiled spring 2 is arranged on pressure sensor 3, and pressure sensor 3 is connected with controller by wire again, thus will pass to the tension feedback of cylindrically coiled spring 2 from steel rope to controller in time, thus the electronic devices and components of proterctive equipment.The bottom of pressure sensor 3 is provided with a pole 6, and this pole 6 is connected with the connecting rod 8 on objective table 7.Overload rope-loosing protection device of the present utility model adopts cylindrically coiled spring, and this kind spring stress amplitude of deformation is comparatively large, can well touch electric elements proterctive equipment; In addition, the overload rope-loosing protection device after improvement also add steel rope pressure sensor, detects the pulling force of steel rope from system background, and when the numerical value that pressure sensor detects exceeds the value range of setting, equipment can send breakdown signal.
