Abstract
The utility model provides a can play safety protection's stop device when outage, it is at hanging flower basket top installation electro-magnet, is connected with the couple through the pull rod, installs the spring on the pull rod, leans on the electromagnetic force to make the couple pull back, leans on the spring action to make the couple open, hooks the support body horizontal pole, plays the purpose of safety stop.
Description
Affiliated technical field
The utility model relates to the elevator machinery safety device, especially the material elevator safety guard.
Background technology
" construction site safety inspection standard " (JGJ59-99) spells out: " hanging basket did not have the stop device button 9 minutes "; in the clause explanation, point out: " at the dangerous unreliable problem of breaking rope protecting existence; change hanging scaffold into; can not only use rope broken protector, must stop device safe in utilization." at present, all to be the mechanical mechanism execution do not shield and be limited to for the hanging basket sudden power that is in operation used safety stop device on the gig.
Summary of the invention
Do not have the problem of reliable and secure protection in order to overcome when outage hanging basket, the utility model provides a kind of safety stop device, can not only play the safety guard-safeguard effect when stopping layer, and can make hanging basket be parked in the support body optional position when sudden power.
The technical scheme that its technical matters that solves the utility model adopts is: alternating electromagnet is installed at the cage top, electromagnet armature is connected with pull bar, spring housing is on pull bar, spring and pull bar are arranged in the sleeve, the hinged hook of the pull bar other end, link up with an end and be hinged on the hanging basket top, whole power supply is by the control contactor control of winch.
Under electromagnet energising situation, armature overcomes spring pressure and is inhaled into, and by pull bar, the pulling hook makes it to enter in the hanging basket zone, and hanging basket just can move up and down.When supply disconnecton, linking is unclamped, and the elastic force of spring works, and pushing drawing rod outwards opens hook, hangs on the support body cross bar, plays the effect of safety guard-safeguard.
The beneficial effects of the utility model are, when hanging basket stops at arbitrary height, can both play safety protection function, and are simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model constructional drawing.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Fig. 4 is the C-C cutaway view of Fig. 1.

The specific embodiment
In Fig. 1, magnet coil (2) is fastened on the adapter plate (1) by bolt (3), armature (4) and pull bar welding, sleeve (6) is supported by stay bearing plate (13) and gusset (14), built-in spring (7), pull bar (8) one ends are installed slidiing pin (9), can slide up and down in the sliding tray of hook (10).
The power supply of magnet coil (2) is by the control contactor control of winch, when hanging basket moves to every layer, also cut off the power supply of magnet coil (2) when cutting off the power supply of winch, electromagnetic force disappears, extrapolated under the effect of spring (7), the promotion hook (10) of pull bar (8), hook (10) is hung on the hanging basket support body cross bar, reach the purpose of safety stop.When the hanging basket rising, during energized, coil (2) one energisings produce electromagnetic force, and armature (4) overcomes spring force and moves inwards, and pull bar (8) pulling hook (10) retracts hook (10), and hanging basket just can move up and down freely.
Claims (3)
1, a kind of material elevator safety stop device connects successively at hanging basket top electromagnet, pull bar, spring, hook, it is characterized in that: pull bar one end connects armature, the intermediate sleeve spring, and the other end connects hook.
2, safety stop device according to claim 1 is characterized in that: spring housing is on pull bar, and spring and pull bar are in sleeve.
3, safety stop device according to claim 1 is characterized in that: open sliding tray on the hook, pull bar is connected in the sliding tray of hook by bearing pin
