Abstract
The utility model discloses a steel cable load detection device comprising a winding drum, a motor and two winding drum bases, wherein two ends of the winding drum are mounted on the winding drum bases respectively; the winding drum is connected with the motor through a gear box; a pressure detection sensor is mounted below each winding drum base, and is connected with the signal input terminal of a PLC; the first control output end of the PLC is connected with the motor through a power amplifier; the second control output end of the PLC is connected with an alarming device; a maximal load limit value is preset in the PLC; and the PLC receives the detected value of the pressure detection sensor in a real-time manner, and compares the detected value with the preset value to judge whether the steel cable is overloaded or not. When the steel cable is overloaded, the motor is controlled to brake to avoid danger, and the alarming device gives an alarm. Through the adoption of the technical scheme, the serious consequence of damage of the steel cable and equipment caused by overloading of a load-carrying object can be avoided efficiently.
Description
Technical field
The utility model relates to a kind of detecting device, especially a kind of cable wire load detecting device.
Background technology
Winch is through rotating drum, with the weight-lifting equipment that is wrapped in the cable wire generation tractive force on the reel.It is a device of being accomplished traction work by mechanical powered drive reel, coiling rope; At present, be main with electric winch, electric winch is made up of motor, coupler, drg, gear case and reel, is installed on the equipment rack jointly.For lifting altitude and the frequent situation of the big work of the volume of goods loaded and unloaded, good speed adjustment features can make empty hook descend fast; To installation in position or responsive material, can use less speed.But at present, the cable on the winch of use does not have load detecting device, and whether the object that the staff can not in time find to draw at the tolerance range of winch, can cause the overweight damage equipment of loading, the serious safety misadventure that very likely also can cause.
The utility model content
The utility model is in order to solve non-detectable problem after the present cable wire load detecting device load, a kind of cable wire load detecting device to be provided for this reason.
The technical scheme of the utility model: a kind of cable wire load detecting device; Comprise reel, motor and two reel bases, the two ends of reel are installed in respectively on two reel bases, and reel is connected through change speed gear box with motor; Equal setting pressure detecting sensor below two reel bases; Press detection sensor is connected with the signal input part of PLC, and first control output end of PLC is connected with motor through power amplifier, and second control output end of PLC connects a warning device.Said warning device comprises the combination of any or the two of buzzer phone, photoelectric display clock.
The beneficial effect of the utility model is:
In PLC, be preset with the load threshold limit value, and receive the detected value of press detection sensor in real time, detected value and preset value are compared; If comparative result is that detected value is greater than preset value; Then explanation is that cable wire has overloaded, and PLC prevents dangerous generation through first control output end control motor braking; And, drive warning device and report to the police simultaneously through the second control output end mouth output alarm signal of PLC.The technical scheme of the utility model has effectively prevented the loads overload to cause the serious consequence of cable wire and device damage.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the utility model cable wire load detecting device structural representation.
The specific embodiment
Disclosed all characteristics in this specification sheets, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Cable wire load detecting device as shown in Figure 1; Said cable wire load detecting device comprises reel 2, motor 5 and two reel bases 1; The two ends of reel 2 are installed in respectively on two reel bases 1; Reel 2 and motor 5 are connected through change speed gear box, equal setting pressure detecting sensor 6 below two reel bases 1, and press detection sensor 6 is connected with the signal input part of PLC7; First control output end of PLC7 is connected with motor 5 through power amplifier 8, and second control output end of PLC7 connects a warning device.During work, starter motor 5, motor 5 rotating band movable reels 2 rotate, and under the rotation of reel 2, cable wire 3 winding reel 2 together rotates, and realizes that cable wire 3 affects loading to reach the purpose that loading is risen.
The utility model is owing to adopted setting pressure detecting sensor under the reel base; Press detection sensor is connected with PLC; The control output end of PLC is connected with motor and warning device, and whether can make overloads to detect automatically to cable wire load is taked the emergency braking measure and in time report to the police.In PLC, be preset with the load threshold limit value, and receive the detected value of press detection sensor in real time, detected value and preset value are compared; If comparative result is that detected value is greater than preset value; Then explanation is that cable wire has overloaded, and PLC prevents dangerous generation through first control output end control motor braking; And, drive warning device and report to the police simultaneously through the second control output end mouth output alarm signal of PLC.The technical scheme of the utility model has effectively prevented the loads overload to cause the serious consequence of cable wire and device damage.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
