In the embodiment, the pressing block 46, the capsule 4151, the fixing frame 4152, the bag breaking needle 4153, the liquid storage bag 4154 and the catalytic liquid 4155 are adopted for matching, the capsule 4151 is compressed by the pressing block 46, the fixing frame 4152 and the bag breaking needle 4153 are driven to move by matching with the deformation of the capsule 4151, and the liquid storage bag 4154 is punctured by the bag breaking needle 4153, so that the catalytic liquid 4155 and the gas inside the capsule 4151 are subjected to chemical reaction and expansion to buffer a huge external force, and the condition that the impact force of pressing down is too large, so that the equipment is damaged and huge economic loss is generated is prevented, and the safety of the equipment is further improved.

The working principle of the derailing prevention safety mechanism of the building construction hoist is described in detail below.

As shown in fig. 1-7, when in use, firstly, the pressure generated when the elevator ascends and descends is transmitted to the second spring pillar 325 through the fixer 327 and the supporting plate 326, the second spring pillar 325 presses the second connecting rod 324 in cooperation with the second spring pillar 325, the first spring pillar 323 is pressed by the movement of the second connecting rod 324 and the first connecting rod 322, the first spring pillar 323 and the second spring pillar 325 are pressed, the elastic modulus changes to generate a reverse acting force to push the fixer 327 to be in closer contact with the elevator body 2 to prevent the elevator body 2 from derailing, meanwhile, the air bag 3262 is compressed by the force of the fixer 327, the first magnetic pole 32621 is driven to move by the change of the internal pressure of the air bag 3262, then, the moving plate 32641 is pushed to move by the characteristic that like magnetic poles of the first magnetic pole 32621 and the second magnetic pole 32642 repel each other, the hemispherical air bag 32633 is compressed by the change of the air pressure of the hemispherical air bag 32633, the pushing plate 32634 is pressed to drive the antirust liquid in the antirust liquid tank 32631 to flow, the catalytic liquid 4155 and the gas in the liquid storage bag 4151 are chemically reacted by matching with the deformation of the bag 4151, driving the fixing frame 4152 and the bag breaking needle 4153 to move and then puncturing the bag 4154 by the bag breaking needle 4153 when the gravity acceleration of the pressure is too high and the over-limit impact is generated when the elevator body 2 descends, so that the catalytic liquid 4155 and the gas in the bag 4151 are chemically reacted, the expansion is generated, and huge external force is buffered, so that the equipment is prevented from being damaged.

The present invention has been described in general terms in the foregoing, but it will be apparent to those skilled in the art that modifications and improvements can be made thereto based on the present invention. Therefore, modifications or improvements are within the scope of the invention without departing from the spirit of the inventive concept.
