The bottom of the fixed plate is connected to an inclined limiting top plate. A limiting Hall magnetic controller is disposed at a position close to the tail end of the limiting top plate. A limiting reporting magnetic controller is disposed below the limiting top plate. The limiting reporting magnetic controller, the breaker controlling limit switch and the limiting Hall magnetic controller are separately connected to the voice module. The intelligent limiting and voice alarm device is provided with the crooked pulling and inclined hoisting preventing device and the intelligent limiter total unit, thus preventing crooked pulling, inclined hoisting and breaking of a steel rope and lifting hook over-hoisting by the hoisting equipment.
Description
Technical field
The present invention relates to the spacing and phonetic alarm device of intelligence for a kind of weight-lifting equipment.
Background technology
Weight-lifting equipment has just become requisite lifting tool since the industrial revolution, in nation-building industry, accounts for consequence, also becomes one of sign of scientific and technological progress.But suspension hook often occurs in the use procedure of enterprise rushes to summit and shell is pushed up flat or steel rope is broken, its major cause: though 1. weight-lifting equipment top limited location bar and two little backstops, because backstop loosened screw causes inefficacy.2. stir backstop spacing be by the baffle plate on rope guide, to stir circuit fire stop cut off to obtain, because craneman often draws when the lifting cargo sideling, hang sideling, and lifting rope device is because holding strength that can't stand oblique pull, steel band is broken and lose effect, circuit fire stop has also just become a kind of ornaments.And operator has a kind of curing phychology sometimes, i.e. limited location switch above, just bold continuation is risen, and hardly realizes that the broken belt weight high-altitude of rushing to summit falls down, and easily causes human casualty accident.
Summary of the invention
The object of this invention is to provide the spacing and phonetic alarm device of intelligence for a kind of weight-lifting equipment, to overcome prior art above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
Spacing and the phonetic alarm device of intelligence for weight-lifting equipment, comprises adapter plate, and described adapter plate is provided with the total unit of Intelligent position limiter, and the total unit of described Intelligent position limiter comprises anti-askew device for hoisting, disconnected control limit switch, voice module and the circuit fire stop of skewing; The bottom of described adapter plate is connected with the spacing top board of an inclination, is provided with spacing Hall magnetic control approaching described spacing top board end, and the below of described spacing top board is provided with spacing report magnetic control; Spacing report magnetic control, disconnected control limit switch are all connected voice module with spacing Hall magnetic control.
Further, the described anti-askew device for hoisting that skews comprises limiting device and the anti-askew pendent switch that skews, and the both sides in the middle of described limiting device are respectively provided with a spring.
Further, the described anti-askew pendent switch that skews connects voice module.
Beneficial effect of the present invention is: the spacing and phonetic alarm device of described intelligence is provided with anti-askew device for hoisting and the total unit of Intelligent position limiter of skewing, prevent weight-lifting equipment askew skew to hang break steel rope and suspension hook is rushed to summit.

The specific embodiment
As Figure 1-4, spacing and the phonetic alarm device of intelligence for a kind of weight-lifting equipment, comprise adapter plate 1, described adapter plate 1 is provided with the total unit 2 of Intelligent position limiter, and the total unit 2 of described Intelligent position limiter comprises anti-askew device for hoisting 3, disconnected control limit switch 4, voice module 5 and the circuit fire stop 6 of skewing; The bottom of described adapter plate 1 is connected with the spacing top board 7 of an inclination, is provided with spacing Hall magnetic control 8 approaching described spacing top board 7 ends, and the below of described spacing top board 7 is provided with spacing report magnetic control 9; Spacing report magnetic control 9, disconnected control limit switch 4 are all connected voice module 5 with spacing Hall magnetic control 8.The described anti-askew device for hoisting 3 that skews comprises limiting device and the anti-askew pendent switch 10 that skews, and the both sides in the middle of described limiting device are respectively provided with a spring 11, and during installation, spring 11 is located at the both sides of steel rope 15.The described anti-askew pendent switch 10 that skews connects voice module 5.
During concrete use, the spacing and phonetic alarm device of described intelligence is applicable on all weight-lifting equipments, and the electric block of take is below introduced its installation and principle of work as object:
Adapter plate 1 is arranged between two steel ropes 15 of connecting shackle device 14 and is positioned at the lower end of cable guiding device clamping plate 13, when suspension hook rises to the spacing top board 7 nearly 400mm in lower end and approaches spacing report magnetic control 9, voice module 5 just can send the prompt tone of " approaching spacing; take care ", reminds operator to note.
If continued again, rise, suspension hook shell upper is pushed up spacing top board 7, touch the control limit switch 4 that will break, now contactless for hoisting coil cuts off, make motor out of service, the closed voice module 5 of connecting of disconnected control limit switch 4 open contacts, sends the warning of " spacing; to take care " simultaneously, and operator is informed on infrared shot-light directive ground simultaneously.
If disconnected control limit switch 4 lost efficacy, suspension hook continues to rise, and the thimble of circuit fire stop 6 is pushed, and the quarter-phase circuit of electrical motor is cut off, and motor has stopped running.Spacing Hall magnetic control 8 open contact under the induction of magnet being simultaneously placed on spacing top board 7 is connected, and voice module 5 sends the warning of " cutoff is spacing, takes care ", and infrared shot-light is directive ground also, informs that operator is spacing.
If operator by lifting thing askew skew to hang surpass 3.5 while spending, spring 11 distortion touch the built-in contact of limiting device, to cut off main contactor coil circuit, complete machine quits work, voice module 5 sends the prompt tone of " safety first; do not allow askew skewing to hang ", and infrared shot-light directive ground, informs operator simultaneously.
When lifting thing recovers normal, motor is again by normal operation.In sum, guaranteeing that rope guide is not easily broken falls, and suspension hook is not rushed to summit, and has protected the safety of operator and equipment.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
