Abstract

The utility model relates to a stereo garage fitting, particularly an anti-drop device for a stereo garage, which comprises a steel framing longitudinal beam and a chain, wherein an anti-drop rack is fastened below the steel framing longitudinal beam and is provided with an electromagnet, a safety clamp, a microswitch and a long slide plate. The long slide plate is provided with a groove. The lower end of the chain is fastened and connected with an anti-drop hook provided with a groove. The safety clamp has one staged side; after the safety clamp rotates a preset position, the front end of the safety clamp is below the groove of the anti-drop hook, and the staged side is just fastened to the groove of the long slide plate. The lower end of the anti-drop hook is fastened and connected with a chassis. The utility model has the advantages of good anti-drop effect, small driving force and high safety.

Description

The multi-storied garage anti-drop device

One, technical field

The utility model relates to a kind of multi-storied garage accessory, relates in particular to a kind of multi-storied garage anti-drop device.

Two, background technology

Multi-storied garage commonly used at present falls for preventing ride, often establishes a hook below steel hook longeron and makes anti-drop device.This anti-drop device is simple in structure, and anti-fall effect is better.But its shortcoming is: the hook volume is big, and required driving force is big when anti-fall.

Three, summary of the invention

The utility model is at above-mentioned situation, and purpose is to provide a kind of small and exquisite sensitivity, and required driving force is little, the multi-storied garage anti-drop device of good reliability.

For achieving the above object, the technical solution of the utility model is: the multi-storied garage anti-drop device, comprise steel structure longeron, chain, steel structure longeron below is fastened with anti-fall, on anti-fall electromagnet is housed, microswitch and long slide plate, be fixed in insurance card on anti-fall by rotating shaft, be wound with torsion spring in the rotating shaft with reset function, have groove on the long slide plate, electromagnet is gone up set bull stick control insurance card rotation by it, and the chain lower end is fastening to be connected with anti-fall hook, anti-fall hook is provided with groove, insurance card its on one side shape be staged, insurance card its front end of back that rotate in place is in the groove below, Yi Bian and it is staged and just in time is fixed on the groove.

The utility model optimal technical scheme is: short slide plate is housed on anti-fall, and anti-fall hook can be upper and lower mobile in the cavity that is made of long slide plate, short slide plate; The fastening ride that is connected with in anti-fall hook lower end.

After the utility model adopts technique scheme, its beneficial effect is: in case abnormal conditions take place, when ride falls, insurance card can be blocked anti-fall hook groove, thereby play the effect that prevents that ride from falling, and just in time be fixed on the long slider groove because of insurance card is shaped as stepped one side, thereby required driving force is little.

Four, description of drawings

Fig. 1 is the utility model overall structure front view;

Fig. 2 is the right view of steel structure longeron described in the utility model and anti-fall and upper-part thereof.

Five, the specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises steel structure longeron 1, chain 7, steel structure longeron 1 below is fastened with anti-fall 2, and electromagnet 3, microswitch 5, long slide plate 10 and short slide plate 11 are housed on anti-fall 2, is fixed in insurance card 4 on anti-fall 2 by rotating shaft 13.Be wound with the torsion spring 12 with reset function in the rotating shaft 13, torsion spring 12 1 ends are fixed in long slide plate 10 bottoms, and the other end is fixed in insurance card 4.Have groove 10a on the long slide plate 10, electromagnet 3 rotates by bull stick set on it 6 control insurance card 4, microswitch 5 contacts fastening anti-fall hook 8, the fastening ride 9 that is connected with in anti-fall hook 8 lower ends of being connected with in chain 7 lower ends with insurance card 4 after insurance card 4 rotate in place.Anti-fall hook 8 can be upper and lower mobile in the cavity that is made of long slide plate 10, short slide plate 11, guaranteed anti-fall hook 8 upper and lower mobile up rightness on the one hand, and the ride 9 that anti-fall on the other hand hook is 8 times also is difficult for double swerve.Anti-fall hook 8 is provided with groove 8a, on one side insurance card 4 its be shaped as staged, insurance card 4 its front end of back that rotate in place is in groove 8a below, Yi Bian and its staged just in time is fixed on the groove 10a.

The utility model operating principle is: ride 9 is after the lifting instruction is sent, and electromagnet 3 is switched on, and insurance card 4 is opened, microswitch 5 closures, after three-dimensional garage control system is received signal, just control the electric motor starting that links to each other with chain 7, chain 7, anti-fall hook 8, ride 9 rise.Insurance card 4 is in the control turning down of electromagnet 3 at this moment, and the torsion spring 12 that is wound in rotating shaft 13 tightens.After rising puts in place, by 3 outages of three-dimensional garage control system control electromagnet.Insurance card 4 is turning under the effect of torsion spring 12 below the groove 8a, Yi Bian and its staged just in time is fixed on the groove 10a, (dotted line position among the figure).Microswitch 5 was opened and was confirmed insurance card 4 positions this moment.So in a single day, abnormal conditions take place, when ride 9 fell, insurance card 4 just can be blocked anti-fall hook 8, played anti-ride 9 effect of falling.
