Abstract
The utility model discloses a kind of anti-wire rope inclined-pulling control setup, be arranged on below cylinder fixed pulley by riser, oblique pull angle is generally between 15 °-30 °, is determined by installation site.Be welded with base plate below riser, base plate be provided with push rod, travel switch, spring.It is characterized in that: base plate has push rod, push rod one end is hinged, the other end is connected with spring.Travel switch is drawn control line and is connected with the power controling box of electric block.Steel rope in fixed pulley hangs down in the outside of push rod.During wire rope inclined-pulling, encounter push rod, push rod is contacted with travel switch, outgoing signal, to controller, controls power-off by controller.The utility model structure is simple, easy for installation, and when lifting promotes, once there is oblique pull, control circuit gets final product power-off, and actv. protects electric block.
Description
Technical field
The present invention relates to the anti-wire rope inclined-pulling control setup of a kind of electric block.
Background technology
In operation, easily there is wire rope inclined-pulling in existing electric block, causes steel rope to be entangled to cylinder, cause steel rope to be scrapped, the fracture of bridge motor end cap, the phenomenon such as speed reduction gearing damage.
Summary of the invention
In order to solve the problem, power-off immediately when the present invention proposes a kind of wire rope inclined-pulling, extends the anti-oblique pull control setup in electric block service life.
Anti-wire rope inclined-pulling control setup provided by the invention, be arranged on below cylinder fixed pulley by riser, oblique pull angle is generally between 15 °-30 °, is determined by installation site.Be welded with base plate below riser, base plate be provided with push rod, travel switch, spring.It is characterized in that: base plate has push rod, push rod one end is hinged, the other end is connected with spring.Travel switch is drawn control line and is connected with the power controling box of electric block.Steel rope in fixed pulley hangs down in the outside of push rod.
During wire rope inclined-pulling, encounter push rod, push rod is contacted with travel switch, outgoing signal, to controller, controls power-off by controller.
Structure of the present invention is simple, easy for installation, and when lifting promotes, once there is oblique pull, control circuit gets final product power-off, and actv. protects electric block.
Accompanying drawing explanation
Fig. 1 is the present utility model structural arrangement schematic diagram.
Fig. 2 is electric block anti-wire rope inclined-pulling control setup partial enlarged drawing.
Description of reference numerals: 1-steel rope, 2-push rod, 3-travel switch, 4-control line, 5-crane AC contactless switch, 6-bridge motor, 7-relay, 8-movable motor ,-riser, 10-base plate, 11-fixed pulley, 12-power controling box.
Detailed description of the invention
The present invention below will further describe by reference to the accompanying drawings:
As shown in Figure 1, principle of work of the present invention is: when oblique pull occurs steel rope 1, and encounter push rod and push rod 2 is contacted with travel switch 3, triggered the normally closed contact of crane AC contactless switch 5 by control line 4, make bridge motor 6 power-off, bridge motor 6 can not work; Utilize travel switch 2 often to make war and control movable motor 8 power-off on oblique pull direction by relay 5, movable motor 8 can not work, thus plays a protective role.
