Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1
As shown in fig. 1-3, a steel wire rope lap winding detection device includes a rope blocking rod 1, where the rope blocking rod 1 includes a connecting rod 1.1 and an extension lever 1.2;
the connecting rod 1.1 is fixed on a hinge shaft seat 7 through hinge shafts 3 at two ends of the connecting rod, one end of the extension lever 1.2 is connected with the connecting rod 1.1, and the other end of the extension lever is connected with the bracket 2 through a sensor 4;
the support 2 is also provided with a support plate 2.1;
the supporting plate 2.1 is fixed on the connecting rod 1.1 through tension springs 6 on two sides of the supporting plate.
The connecting rod 1.1 and the extension lever 1.2 are arranged perpendicular to each other.
The connecting rod 1.1 rotates around a hinge shaft seat 7 through an adjusting bolt 5 above the connecting rod.
The hinge shaft seat 7 is fixed on the bracket 2 through mounting seats 8 at two sides of the hinge shaft seat.
The rope blocking rod 1, the hinge shaft 3, the hinge shaft seat 7 and the mounting shaft 8 are modules, so that the quick replacement is convenient.
The number of the sensors 4 is a plurality, and the sensors are used for transmitting signals to the PLC and controlling the operation of the device.
In the device, a rope blocking rod 1 is fixed on a hinge shaft seat 7 through a connecting rod 1.1 by a hinge shaft 3, and the hinge shaft seat 7 is fixed on a support 2 through a mounting seat 8. The rope blocking rod 1 rotates around the hinge shaft seat 7, the connecting rod 1.1 is fixedly connected to the supporting plate 2.1 through the tension spring 6, the connecting rod 1.1 keeps in contact with the adjusting bolt 5 through the elasticity of the tension spring 6, and the rope blocking rod 1 keeps stable when the crane runs. The extension lever 1.2 is in contact with two sensors 4. Wherein, the rope blocking rod 1, the hinge shaft 3, the hinge shaft seat 7 and the mounting shaft 8 are a module which can be replaced quickly.
Adjusting the adjusting bolt 5 enables the connecting rod 1.1 to rotate around the hinge shaft seat 7, the gap S between the rope blocking rod 1 and the winding drum can be correspondingly changed, and after the gap S is adjusted, the distance between the sensor 4 and the extension lever 1.2 is adjusted, so that the adjustment of the detection sensitivity is realized.
Specifically, when the steel wire rope is wound or jumps out of the rope groove, the rope blocking rod 1 is pushed to slightly rotate around the hinge shaft seat 7 when the winding drum rotates, and the action is amplified through the extension lever 1.2. The end of the extension lever 1.2 will be far from the sensor 4 and any one sensor 4 will give a signal to the PLC controller. The PLC controller gives an alarm signal and stops the operation of the hoisting mechanism.
