Further, the safety baffle both ends are provided with the sleeve, be provided with guide bar and the guide post that is used for vertical direction to go up and down in the sleeve respectively.

Furthermore, the fixed step ladder is a steel plate type stair or a steel beam type stair.

Further, the escalator step width size of the escalator is not less than 50 cm.

Furthermore, a safety handrail is arranged on the outer side of the escalator or the fixed step ladder.

The utility model has the advantages that:

1. the device of the utility model applies the escalator and the fixed step ladder to the building stairs simultaneously, which not only can provide more convenient upstairs service for people who do not have the elevator or are difficult to upstairs; meanwhile, the ladder can be shared with a fixed step ladder on one side in a certain occasion, and more flexible and spacious stair space is provided.

2. The lifting baffle device in the device can automatically rise, stop and automatically fall back before the escalator operates so as to ensure that the escalator step is consistent with the steel step ladder; the complete function of the stairs walking downstairs is ensured, and the clamping accident caused by friction and shearing with a static fixed stepping ladder is avoided; meanwhile, the escalator can be lowered into the lifting interlayer to be hidden when not running; is more intimate and convenient.

3. The utility model discloses well overhead gage device adopts worm gear's transmission structure, has utilized the one-way driven reverse self-locking function of worm gear, can avoid the uncontrolled condition that descends and damage when the overhead gage receives the heavy load.

4. The invention can solve the problem that the old and new buildings within ten floors are difficult to go upstairs; the old building does not need to invest hundreds of thousands of additional vertical elevators; the device does not need to wait for going upstairs, and is energy-saving, safe and convenient.

Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-5, the specific structure of the present invention is: a multifunctional combined safety stair comprises an escalator 3 and a fixed step 6, wherein the escalator 3 and the fixed step 6 are arranged in a corridor 1 between stair platforms 2; the escalator 3 and the fixed step 6 are arranged in parallel at two sides of the corridor 1, and a lifting interlayer 8 is arranged between the escalator 3 and the fixed step 6; a lifting baffle device 5 is arranged in the lifting interlayer 8; the lifting baffle device 5 comprises a lifting driving motor 501 arranged at the bottom of the stair platform 2, a worm 502 is arranged on the lifting driving motor 501, and a worm wheel 503 matched with the worm 502 is arranged on one side of the worm 502; the other side of the worm wheel 503 is provided with a single-sided toothed plate 504 matched with the worm wheel, and the single-sided toothed plate 504 is arranged on a safety baffle 505; the safety barrier 505 is disposed in the lifting mezzanine 8.

In order to make the lifting of the safety barrier 505 more stable, sleeves 506 are arranged at two ends of the safety barrier 505, and guide rods 507 and guide columns 508 for vertical guide lifting are respectively arranged in the sleeves 506.

Preferably, the fixed step ladder 6 is a steel plate type ladder or a steel beam type ladder.

Preferably, the width dimension of the escalator step 4 of the escalator 3 is not less than 50 cm.

Preferably, a safety handrail 7 is provided outside the escalator 3 or the fixed step 6.

The device has the following working principle that when the escalator works, the lifting driving motor drives the worm to rotate to drive the worm gear to rotate and further lift the single-face toothed plate matched with the worm gear, and the safety baffle gradually rises to the upper parts of the escalator and the fixed step ladder in the corridor through the lifting interlayer to play a role in protection and separation; when the escalator stops operating, the lifting driving motor rotates reversely to drive the safety baffle to descend, so that the escalator steps and the fixed stepping ladder of the escalator are shared, and the escalator is suitable for more upstairs operation.
