Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to FIGS. 1-2, the present invention provides

A mechanical delay door opening protection device for the middle floor of a high-altitude elevator comprises an elevator car 1, a plurality of floor sliding doors 2 arranged in the floor are arranged along the up-down moving direction of the elevator car 1, the elevator cage 1 is provided with a jacking part 3, a pressure delay damper 4 is arranged in the floor at one side of the floor sliding door 2, the input end of the pressure delay damper 4 close to the top pressing part 3 is provided with a pulley 5, the input end of the pressure delay damper 4 far away from the top pressing part 3 is provided with a first hinged end 6, a swing locking rod 7 for limiting the transverse movement of the sliding door 2 of the corresponding floor is arranged in the floor below the pressure delay damper 4, a second hinged end 8 is arranged on the swing locking rod 7, and a connecting rod 9 is hinged between the first hinged end 6 and the second hinged end 8;

the working principle of the structure is as follows:

the elevator car 1 moves up and down in the height direction and the pressure delay damping 4 will take the following two actions:

the first action is as follows: when the elevator car 1 rapidly passes through the corresponding middle floor, one end of the top pressure part 3, which is used for pressing the pressure delay damper 4, is contracted, and the passing time is short (usually about 1 second), the top pressure part 3 rapidly presses one end of the pressure delay damper 4 and then resets, the other end of the pressure delay damper 4 does not have reaction time, and the other end does not do any action, so that the swing locking rod 7 cannot be unlocked, and the floor sliding door 2 of the corresponding floor cannot be opened; the floor sliding door 2 is protected from being opened by mistake.

And the second action: when elevator car 1 stops one of them floor sliding door 2 position of middle floor (long-time stop, for example after 3 seconds), roof splenium 3 lasts roof pressure time delay damping 4's one end, make the 4 other ends of pressure time delay damping possess reaction time, the other end slowly stretches out, it stretches out and draws back to drive first hinged end 6 outside, first hinged end 6 pulling connecting rod 9 this moment, connecting rod 9 pulling swing locking pole 7 overturns to the outside, swing locking pole 7 that is used for the restriction to correspond 2 lateral shifting of floor sliding door is opened (accomplishes the unblock) originally, it can cross 7 positions of swing locking pole to correspond floor sliding door 2 this moment and open the action, be used for ensuring that elevator car 1 stops when middle floor sliding door 2 position, the middle floor sliding door 2 that corresponds just can the unblock.

Pressure time delay damping 4 transversely sets up in the floor.

Be provided with first slope spigot surface 301 and second slope spigot surface 302 on top splenium 3.

In the utility model, a fillet is arranged at the included angle between the first inclined guide surface 301 and the second inclined guide surface 302;

the first inclined guide surface 301 and the second inclined guide surface 302 are provided in order to allow the pressing portion 3 to smoothly pass over or press one end of the pressure delay damper 4 in the height direction.

Swing lock pole 7 is including setting up at the intraformational third hinge end 701 of corresponding building, it has lock pole 702 to articulate on the third hinge end 701.

Second hinged end 8 sets up the middle part position of swing lock pole 7.

Swing lock pole 7 set up in for 4 opposite sides of pressure time delay damping of first hinged end 6.
