Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, Fig. 2, Fig. 3, a kind of electric block with emergent release function, comprise mechanical drive and the control setup 200 of electric block, the side of mechanical drive and control setup 200 is provided with motor 300, one end of motor 300 is provided with other magnetic draw gear 303, the centre of other magnetic draw gear 303 be provided with motor 300 do not work or power failure state time side magnetic braking device 304 be close to the retarding spring 311 of electric motor end cap 310, the top of electric motor end cap 310 is provided with the fixed mount 306 for fixing emergent releasing bracket 312, emergent release push rod 307 acts on side magnetic braking device 304 by emergent releasing bracket 312, motor 300 braking force reduces and enables to occur that load is transferred safely to ground by the electric block of emergency situations, meet an urgent need release push rod 307 through the cored screw 305 offered in the middle part of electric motor end cap 310 near side magnetic braking device 304, due to the effect of emergent release spring, motor under normal circumstances, emergent release push rod and side magnetic braking device keep suitable distance, emergent release push rod 307 is connected emergent release spring 308, emergent releasing bracket there is emergent release lever 309.
In addition, motor 300 inside include motor stator 302, around rotor axis of electric rotate Rotor Assembly 301.Emergent release push rod 307 works by emergent releasing bracket 312, and the quantity of emergent release push rod 307 is two.Emergent release push rod 307 is symmetric on electric motor end cap 310, adopts detachable connection between emergent release lever 309 and emergent release push rod 307.
Mechanical drive and control setup 200 side are connected with chain bag 600, the opposite side of mechanical drive and control setup 200 is provided with the button switch assembly 800 controlling moving direction, the inner holding of chain bag 600 has load chain 500, and the below of load chain 500 is provided with end position spring 400.The upper end of load chain 500 is provided with hook 100, and the lower end of load chain 500 is provided with lower suspension hook 700, and hook 100 and lower suspension hook 700 are provided with safety tongue above.
Use procedure of the present utility model is: motor internal includes motor stator 302, Rotor Assembly 301, motor do not work or power failure state time side magnetic braking device 304 on Friction disk be close to electric motor end cap 310 because retarding spring 311 acts on, make motor be in braking mode. when motor normal electric work time other magnetic draw gear 303 produce electromagnetic traction power and electric motor end cap 310 left in side magnetic braking device 304 traction and makes motor normal operation. emergency release is installed on electric motor end cap 310, emergency release comprises cored screw 305, fixed support 306, emergent release push rod 307, emergent release spring 308, emergent release lever 309, emergent releasing bracket 312, wherein emergent release lever 309 is removable under normal circumstances, emergent releasing bracket 312 be install with on fixed support 306 and emergent releasing bracket 312 can only be promoted to ring-chain hoist direction, on electric motor end cap 310, symmetry is equipped with two cored screws 305, two emergent release push rods 307 are symmetric and are through in two cored screws 305, between emergent release push rod 307 and cored screw 305, symmetry is respectively equipped with an emergent release spring 308.When motor normally works, emergent release push rod 307 leaves side magnetic braking device 304 because of emergent release spring 308, when there is emergency situations motor dead electricity or burning and cannot work, the load that often may hoist still is positioned in the air, now emergent release lever 309 is threaded onto on emergent releasing bracket 312, hand push is had to meet an urgent need release lever 309 to a angle, emergent release push rod 307 pushes up to side magnetic braking device 304 by emergent releasing bracket 312, the Friction disk on side magnetic braking device 304 is made to depart from electric motor end cap 310, because braking force is more and more less, rotor slowly rotates due to the Action of Gravity Field of lifted weight, hung load can be made slowly to drop to platform or ground, thus the emergent release function of electric block under the emergency situations such as burn-down of electric motor or power failure suddenly can be realized, improve the safety performance of electric block.
