Beneficial effects of the present invention:

(1) In the emergency braking device for a lift elevator according to the present invention, four guide structures are provided at the four corners of the elevator body, and the guide structures and the limit structure are slidably connected, which increases the difference between the guide structure and the limit structure. The contact area between the guide structure and the limit structure makes the sliding of the guide structure and the limit structure more stable, makes the elevator body more stable during the lifting process, and effectively avoids the uneven placement of construction items on the elevator body. The quality of the elevator is higher, that is: during the lifting process of the elevator body, the elevator body drives the sliding between the storage box and the guide rail, and at the same time rolls between the guide wheel and the limit groove, the two ends of the guide wheel are truncated, and the cross section of the limit groove The trapezoidal shape increases the contact area between the guide wheel and the limit slot, effectively preventing the uneven placement of items from causing the storage box and the guide rail to shift, and at the same time, the sliding friction between the storage box and the guide rail is transformed into the guide wheel and the limit slot. The rolling friction between the two guide wheels makes the sliding more flexible, and the gear between the two guide wheels is connected with the guide shaft in rotation, so that the gear and the rack mesh and roll, and then the four corners of the elevator body are vertically oriented. Carry out the guide limit, so that the four gears are on the same horizontal plane, so that the four sets of guide wheels roll synchronously with the limit groove.

(2) In the emergency braking device for an elevator according to the present invention, the inside of the guide structure is provided with a non-slip structure for limiting the guide structure and the limit structure, and the drive structure is arranged inside the guide structure. When the sliding speed between the structure and the limiting structure is abnormal, the guiding structure controls the driving structure to drive the anti-skid structure to brake the guiding structure, so that the elevator is braked urgently, which improves the running stability of the elevator and avoids the breakage of the elevator wire rope or other abnormalities. Accident occurs; when the elevator wire rope on the motor body breaks or the system fails, the rolling speed of the gear and rack is too fast, and the rolling speed of the guide wheel and the limit groove is too fast, so that the guide wheel rotates rapidly, and the guide wheel rotates rapidly. The bumps of the sliding block interfere with the slider, and the slider and the storage box are slidably connected, thereby reducing the volume of the accommodating cavity. When the pressure inside the accommodating cavity changes too much, the airflow cannot be completely discharged from the trachea, thereby driving the pusher. The block slides with the storage box, so that a second return spring connected to the push block is extended, so that the push block contacts the button switch, so that the button switch is connected to the first hydraulic cylinder, and the storage box is provided with a plurality of When the second reset spring connected to the sliding block drives the sliding block to reset, the air immediately enters the accommodating cavity completely, so that there is enough air flow to push the push block, and at the same time, the air pipe is used to promote the air circulation, and the elevator components are carried out. Cooling, thus improving the stability of use, the first hydraulic cylinder is extended, the first hydraulic cylinder pushes the drive rod and the guide shaft to slide, so that the drive rod pushes the transmission block and the guide shaft to slide, so that the transmission block pushes the rubber pad against the gear, the gear The friction between the gear and the guide shaft increases, which reduces the speed between the gear and the guide shaft until it stops. When the gear and the guide shaft cannot rotate, the gear and the rack are engaged in the limit, so that the storage box and the guide rail cannot slide. Perform emergency braking on the elevator body.

(3) In the emergency braking device for an elevator according to the present invention, the cleaning structure is arranged inside the guide structure, which is convenient for cleaning the waste chips inside the limit structure through the cleaning structure, so that the transmission between the guide structure and the limit structure is facilitated. More stable, that is: when the rack needs to be cleaned, the second hydraulic cylinder drives the sliding sleeve and the storage box to slide to a suitable position, so that the cleaning sleeve can contact the rack, and when the storage box moves, the cleaning sleeve and the rack are rolled, The rotating shaft on the cleaning sleeve is connected to the shrapnel, so that the scope of activity of the cleaning sleeve is larger, which is convenient for cleaning the serrated rack. At the same time, the trachea blows the rack to make the cleaning effect better. The transmission is more stable.

(4) In an elevator emergency braking device according to the present invention, the lubricating structure is arranged on the guiding structure, so that when sliding between the guiding structure and the limiting structure, lubricating oil is applied to the limiting structure through the lubricating structure, This avoids high-altitude operations, and at the same time makes the lubricating oil more effective; that is, unscrew the end cap and add lubricating oil to the interior of the storage bucket, adjust the depth of the storage bucket screwed into the storage box according to the single application amount, and the gears interfere with the fiber cotton sleeve. The sliding between the driving piston and the end cover makes the fiber cotton sleeve and the interior of the storage barrel conduct, and the piston is reset by the first return spring, so that the lubricating oil is evenly applied to the gear, and then applied to the rack through the gear, and then Makes the application of lubricating oil more even.
