Abstract
The utility model relates to a device for preventing a coiling steel wire rope of a hoisting machine from being disordered and belongs to the technical field of mechanical equipment. An infrared emitter (3) and an infrared receiver (4) are respectively arranged at the two ends of a crane cantilever on the back side of a drawing steel wire rope drum (1), are connected with a driving motor through a control circuit, are horizontally arranged and are parallel to the axial direction of the drawing steel wire rope drum (1). When a hoisted object swings to a large extent or is hoisted in an inclining way, the loose steel wire rope enters an infrared emitting area, the receiver sends a signal, the signal is transmitted to the control circuit to stop the driving motor, and an alarm is connected to prompt an operator that a failure is caused at a position. The phenomenon that the steel wire rope is clamped and broken is eliminated substantially.
Description
Technical field
The utility model relates to the roller steel wire that the prevents elevator machinery random device of restricting away, belongs to mechanical equipment technical field.
Background technology
Elevator machinery handling object is undertaken by the reel Wound steel rope, and when the driving elevator in the elevator machinery or reinforced when climbing the car drop hook in normal operation, the steel rope on the reel can normal winding; Yet when the object of handling rocks and shakes when big, the lifting object that tilts draws steel rope askew; Haulage cable can not closely be wound on the reel; Steel rope occurs and become flexible, walk random, stuck, phenomenon such as strand is disconnected, responsible accident is produced in serious will causing, therefore; Be necessary to design a kind of roller steel wire that can prevent elevator machinery random device of restricting away, fundamentally stop the situation that steel rope is stuck, strand is disconnected and take place.
Summary of the invention
The purpose of the utility model provides a kind of roller steel wire that prevents elevator machinery random device of restricting away.
The utility model technical scheme: the rear side jib boom two ends of traction steel wire rope reel are respectively equipped with RF transmitter and receptor; RF transmitter is connected with drive motor through control circuit with receptor, RF transmitter and receptor be horizontally disposed with and with the axially parallel of traction steel wire rope reel.
Longitudinal interval distance between the infrared ray of RF transmitter emission and the outer cylinder body of traction steel wire rope reel is greater than the diameter of a haulage cable, less than the diameter sum of two haulage cables.
The utlity model has easy and simple to handle; When bigger or askew skewing when hanging situation appears rocking in the object of handling; Loosening steel rope gets into the infrared zone, and receptor just can go out a signal, is transported to control circuit and stops drive motor; And the connection siren horn, break down in this place of alert.Can fundamentally stop the situation that steel rope is stuck, strand is disconnected takes place.

Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 1 driving circuit schematic diagram.
The specific embodiment
The utility model can do further to describe to the utility model through following embodiment, yet the scope of the utility model be not limited to following embodiment through the technological practical implementation of explaining in the technical scheme.
Embodiment 1:
The rear side jib boom two ends of traction steel wire rope reel 1 are respectively equipped with RF transmitter 3 and receptor 4; RF transmitter 3 is connected with drive motor through control circuit with receptor 4, RF transmitter 3 be horizontally disposed with receptor 4 and with the axially parallel of traction steel wire rope reel 1; Longitudinal interval distance between the infrared ray of RF transmitter 3 emissions and the outer cylinder body of traction steel wire rope reel 1 is greater than the diameter of a haulage cable, less than the diameter sum of two haulage cables.
When the infrared zone of projector 3 and receptor 4 has no object, receptor 4 normal operation, the electrical motor that drives traction steel wire rope reel 1 is normal operation also; When bigger or askew skewing when hanging situation appears rocking in the object of handling; It is loosening that haulage cable 2 has part, and loosening steel rope gets into the infrared zone, and receptor 4 just moves and provide a signal; Be transported to control circuit; Stopping drive motor through control circuit, and connect siren horn, breaks down in this place of alert.
The driving circuit principle: the contact a of infrared remote receiver 4 is closed; Driving relay b coil gets electric, and the contact C of relay b becomes disconnection by closure, drives drop hook main contactor d coil losing electricity; Drive motor is shut down; Reaching the control purpose, and the contact e of relay b becomes the closed annunciator f that drives by disconnection and carries out the warning reminding operating personal, and the roller steel wire rope breaks down.
Claims (2)
1. a roller steel wire that prevents elevator machinery random device of restricting away; It is characterized in that: the rear side jib boom two ends of traction steel wire rope reel (1) are respectively equipped with RF transmitter (3) and receptor (4); RF transmitter (3) is connected with drive motor through control circuit with receptor (4), RF transmitter (3) and receptor (4) be horizontally disposed with and with the axially parallel of traction steel wire rope reel (1).
2. the roller steel wire that the prevents elevator machinery according to claim 1 random device of restricting away; It is characterized in that: the longitudinal interval distance between the infrared ray of RF transmitter (3) emission and the outer cylinder body of traction steel wire rope reel (1) is greater than the diameter of a haulage cable, less than the diameter sum of two haulage cables.
