Abstract
The invention relates to mining electric technologies, in particular to a magnetic induction overwinding preventing device for a winch. The device aims at protecting the winch reliably when the winch overwinds, immediately stopping the winch from operating, guaranteeing personnel security and running of the winch. The device comprises a magnetic sensor installed on a track roadbed. No tracks are distributed on the installation area of the magnetic sensor, and the installation area is located in a winch safety position. A normally open contact of the magnetic sensor is connected with an intermediate relay ZJ in series. A contact of the intermediate relay ZJ is connected to a control loop of a winch motor. The magnetic induction overwinding preventing device has the advantages that the transport accident rate is reduced, the serious transport accident of winch overwinding is effectively avoided, and safety production can be realized smoothly; meanwhile, various material and part investment caused by accidents is reduced, the production cost is reduced, it is ensured that the winch operates safely and efficiently, and remarkable economic benefits are gained.
Description
Technical field
The present invention relates to a kind of mine electrical technology, particularly relate to winch transport overwinding safety gears.
Background technology
In the existing winch transportation in mine; generally be provided with " a slope third gear " protection, the protection of hypervelocity hanging beam, pull hanging beam protection, overcurrent protection etc.; but because reliable and effective protection cannot be realized when a variety of causes causes lifting vehicle to exceed the pulleying of perch winch in practical operation, in actual production process, still can not meet the demand of transportation safety completely.The safety of winch pulleying to personnel causes high risks, and damage equipment is comparatively serious simultaneously, affects the safety in production in mine.
Summary of the invention
The object of the invention is, when winch pulleying, to provide failure-free to protect, stop winch running immediately, ensure the running of personal security and equipment.
For achieving the above object, the technical solution used in the present invention is:
A kind of winch magnetic induction overwinding safety gears; comprise the sensor be arranged on track bed; rail-free distribution above the installing zone of sensor; installing zone is positioned at winch shear position; the open contact of sensor is connected with intermediate relay ZJ, and the contact of intermediate relay ZJ is connected in the control loop of winch motor.
According to described a kind of winch magnetic induction overwinding safety gears, described sensor is vortex type proximity switch, and the installing zone length of sensor is 0.1-0.5m, has orbit distribution before and after installing zone, and installing zone is at least equipped with a sensor.
According to described a kind of winch magnetic induction overwinding safety gears, described sensor is arranged on the side of track bed, and the induction end of sensor is towards the inner side of track.
According to described a kind of winch magnetic induction overwinding safety gears, described sensor is arranged on above track bed, and upward, induction end is arranged in track bed and does not leak outside the induction end of sensor.
Advantage of the present invention is: use winch magnetic induction overwinding-proof fender guard, reduce shipping accident rate, effectively prevent the appearance of winch pulleying transport serious accident, ensure carrying out smoothly of safety in production; Decrease the input of the various material accessories caused because of accident simultaneously, save production cost, ensure winch shear high-efficiency operation, economic benefit is obvious.

Detailed description of the invention
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Pulleying refers to that winch is in the process of improving material, forgets and stops winch or lifting winch hypervelocity and other reason, and make the material of lifting, exceeded the position that it should stop, had a strong impact on production safety because of operating personal.This device, when perch crossed by mine car, can stop winch timely automatically, prevention shipping accident.
This device, as a kind of winch magnetic induction overwinding safety gears, mainly comprises the sensor 3 be arranged on track bed 4.Sensor 3 is vortex type proximity switch, such as ferromagnetic switch 5.When sensor 3 is close to the right edge of wheel or wheel hub, the open contact of sensor 3 will close.
Above the installing zone of sensor 3, rail-free 1 distributes, and prevents misoperation.Installing zone is positioned at winch shear position.As Figure 2-3, the open contact of sensor 3 is connected with intermediate relay ZJ, and the open contact of intermediate relay ZJ is connected in the control loop of winch motor.
As shown in Figure 1, winch vehicle front is perch.The installing zone length of sensor 3 is 0.1-0.5m, has track 1 to distribute before and after installing zone, and installing zone is at least equipped with a sensor 3.The side that sensor 3 can be arranged on track bed 4 is for sense vehicle wheel to inside edge, and the induction end of sensor 3 is towards the inner side of track 1; Sensor 3 also can be arranged on above track bed 4, and for induction wheel pair, upward, induction end is arranged on track bed 4 li to the induction end of sensor 3, not protruding, prevents from damaging.
In order to prevent sensor 3 misoperation from causing mistakenly stop machine, installing zone should forbid vehicle to pass through, and both sides install guard rail additional or establish poster, prevents metal objects from passing through.
The ferromagnetic sensor installed in track; when lifting vehicle crosses perch; ferromagnetic sensor sensing wheel of vehicle passes through; magnetic induction signal is converted into electric signal; intermediate relay ZJ connected by ferromagnetic switch 5, and intermediate relay ZJ adhesive forms path makes open contact close, and the control loop then controlling winch switch forms the power-off of path master cock; prevent vehicle from breaking through perch, reach the object of protection personnel and equipment.
Embodiment recited above is only be described the preferred embodiment of the present invention; not design of the present invention and protection domain are limited; under the prerequisite not departing from design concept of the present invention; the various modification that in this area, common engineering staff make technical scheme of the present invention and improvement, all should fall into protection scope of the present invention.
