Abstract
The utility model provides an anti-inclined pull device for electric hoists. The device is designed to put sensors into two umbrella faces. The contact surfaces make insulation sealing clipped so as to get an insulated box, which is fixed on the side of the splint. On the central position of the upper umbrella surface, an inclined pull bracket is fastened on the side of the splint in order to make the bracket more secure. The wire rope on the fixed end of the external housing for the wire rope spool of the electric hoist passes and gets clamped through the guide groove fixed inside the wire rope splint. A sensor is arranged inside another umbrella surface via the conductive metal ball. Two conductive poles are available with the sensor and a conductor which is located inside the other umbrella surface. When the wire rope gets inclined, the conductive metal ball rolls and contacts with the conductor. Then the sensor transfers signals to the controller which controls the power-off.
Description
Technical field:
The utility model relates to a kind of electric block when promoting weight, operates against regulations and the anti-a kind of outage limiting device that tiltedly draws.
Background technology:
Existing electric block is when promoting weight, because out of plumb promotes or operative employee's error in judgement, operate and cause the damage of electric block rope guide against regulations, even the overlapping row of steel rope is around deviating from from reel, hold the reel axis body, make electric block self outer cover draw bad, scrap, even cause motor to damage.
Summary of the invention:
Task of the present utility model is to propose a kind of can control when electric block tiltedly draws to cut off the power supply immediately, is convenient to install, and is easy to operate, prolongs the electric block inclined drawing prevention device of electric hoist in service life.Task of the present utility model is finished like this, inclined drawing prevention device of electric hoist, it comprises electric block, the steel rope that twines in the reel, it is characterized in that: described anti-oblique drawing device is that sensor is contained in two umbrella covers, its contact surface insulated enclosure fastens forms the side that a non-conductive box-like body is fixed on clamping plate, the center design of one of them exumbrella has one tiltedly to draw support to be fastened on the side of clamping plate, so that make it more firm, in the guide groove of the steel rope on the electric block cable drum outer cover fixed end in the fixing steel wire clamping plate by clamping.Sensor be by conductive metal balls be placed in the umbrella cover with its another umbrella cover in electric conductor form two conductive electrode, the steel rope back conductive metal balls that tilts is rolled with after electric conductor contacts thereupon, sensor passes the signal along to controller, by controller control outage.The utlity model has following effect: this inclined drawing prevention device of electric hoist is convenient to install, and is easy to operate, and during motor lifting work, once take place tiltedly to draw, control circuit can cut off the power supply, and has protected electric block effectively.
Description of drawings:
Fig. 1 is the utility model structural representation;
Drawing explanation: 1, exumbrella, 2, box, 3, tiltedly draw support, 4, steel rope, 5, clamping plate, 6, guide groove.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing; Sensor is made up of conductive metal balls and electric conductor umbrella cover, conductive metal balls is placed on one and is inverted 1 li of umbrella cover, another umbrella cover is another electric conductor, two umbrella covers snap together the phase-contact surface insulation, form a face area non-conductive box-like 2, be fixed on the side of clamping plate 5 by drift bolt box-like 2, the center design of one of them exumbrella has one tiltedly to draw support 3, by being bolted to the side of clamping plate 5, so that make it more firm, the steel rope fixed end on the electric gourd drum outer cover passes through in the guide groove 6 of 5 li on clamping plate.When electric block promotes weight; steel rope takes place tiltedly to draw; conductive metal balls in the box is rolled thereupon and is contacted with electric conductor; sensor output closure signal; the normally closed contact of the rising ac contactor coil in the control circuit disconnects; the outage of rising ac contactor coil, last lifting motor quits work, and has protected electric block effectively.
Claims (2)
