Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
As shown in Figure 1 and Figure 2; a kind of electric block oblique pull detection protection device; including electric block body 1, be located at the reel 2 of electric block body 1, the steel wire rope 3 being located on described reel 2, have rope outlet 41 rope guide 4 and and described steel wire rope 3 connect suspension hook 5 and power-supply controller of electric 6, also include the oblique pull testing agency 7 whether oblique pull operationally occurs for detecting the described steel wire rope 3 being arranged in described rope outlet 41. Former and later two rope outlet 41 places of electric block body 1 are equipped with oblique pull testing agency 7, and oblique pull testing agency 7 and power-supply controller of electric 6 wireless connections are to control the duty of electric block. Steel wire rope 3 can be fitly arranged on reel 2 to prevent steel wire rope 3 chaotic overlapping by rope guide 4, rope guide 4 can not rotate itself, when reel 2 rotates, wind with steel wire rope 3, driven by thread groove and be axially moveable, the steel wire rope 3 being wound around introduces, draws the helicla flute of reel 2 at any time exactly, and steel wire rope 3 is discharged by the rope outlet 41 of rope guide 4. Rope guide 4 includes arc pressuring plate and described arc pressuring plate is fixed the end rope guide block of connection, multiple middle rope guide block and adjacent two rope guide blocks are fixed the fixing parts of connection, outer conductor rope mouth that described rope outlet 41 includes being located on described arc pressuring plate and be located on the rope guide block of described end and described outer conductor rope mouth position accordingly in conductor rope mouth. Fixing parts include connecting plate and trip bolt. Fixing parts are by end rope guide block, and middle rope guide block and arc pressuring plate are fixedly connected into one, simple in construction.
Embodiment one as shown in Figure 3, oblique pull testing agency 7 includes the touching formula switch 701 being located on described rope guide 4 and being positioned at described steel wire rope 3 both sides, and when steel wire rope 2 oblique pull occurs and exceedes the oblique pull scope of permission, steel wire rope 2 contacts with touching formula switch 701. Touching formula switch 701 disconnection, and send out-of-work signal to the power-supply controller of electric 6 on electric block body 1. Power-supply controller of electric 6 cuts off working power, makes electric block quit work, thus protecting electric block. When steel wire rope 2 returns to normal condition from heeling condition, touching formula switch 701 closes again, and send the signal worked on to the power-supply controller of electric 6 on electric block body 1, power-supply controller of electric 6 receives the signal worked on that touching formula switch 701 transmission comes, and makes electric block work on. The method effectively detected the oblique pull situation of electric block and serves the effect of protection electric block.
Embodiment two as shown in Figure 4, oblique pull testing agency 7 includes pillar load sensor (702), the sliding tray 703 being located on described rope outlet 41 side, the slip impact block 704 being located in described sliding tray 703, be located at described slip impact block 704 end for the guide wheel 705 contacted with described steel wire rope 3, for limit described slip impact block 704 to the limiting section 706 of described pillar load sensor 402 direction sliding distance and for described slip impact block 704 reset back-moving spring 707. When oblique pull occurs steel wire rope 3, steel wire rope 3 first contacts the guide wheel 705 rubbed contact with for reducing, and then pushes guide wheel 705 to pillar load sensor 702 in the lump together with the slip impact block 704 being positioned at sliding tray 703. When slip impact block 704 touches pillar load sensor 702; pillar load sensor 702 sends out-of-work signal to the power-supply controller of electric 6 on electric block body 1; power-supply controller of electric 6 cuts off working power, makes electric block quit work, thus protecting electric block. There is below sliding tray 703 limiting section 706, limit the distance that slip impact block 704 slides to pillar load sensor 702, it is prevented that slip impact block 704 damages pillar load sensor 702 because clashing. It is provided with elastic reset part 707 between pillar load sensor 702 and slip impact block 704, after slip impact block 704 touches pillar load sensor 702, is pushed away counter for sliding shoe 704 so that steel wire rope 3 resets by elastic reset part 707. After steel wire rope 3 resets, pillar load sensor 702 sends the signal worked on to the power-supply controller of electric 6 on electric block body 1, and power-supply controller of electric 6 receives the signal worked on that pillar load sensor 702 transmission comes, and makes electric block work on. Limiting section 706 includes being located at the confined planes bottom described sliding tray 703, makes to leave between slip impact block 704 and elastic reset part 707 gap of necessity. Wherein, elastic reset part 707 is disc spring. The method effectively detected the oblique pull situation of electric block and serves the effect of protection electric block.
The advantages such as this utility model has simple in construction, easy to operate, and oblique pull Detection results is good.
