Technical Field

The invention relates to an escalator system, in particular to a handrail inlet device applied to the escalator system.

Background

At present, the escalator system is used in places such as supermarkets, markets, movie yards and the like to realize the ascending and descending of floors, and the handrail entrance device is provided with door wings and an outer frame for a handrail which moves in a reciprocating manner, so that objects, particularly small hands of children, are prevented from being clamped at the entrance of the handrail. However, the door wing is not firmly arranged, and is easily broken through by brute force and opened by impact, so that the escalator system is forced to stop operation, and if a human hand is clamped, life danger is caused.

Disclosure of Invention

The present invention is directed to overcome the above-mentioned disadvantages and to provide a handrail entry safety device, which is difficult to open the door wings and effectively protects the door wings.

The purpose of the invention is realized by the following technical scheme: the handrail entrance safety protection device comprises an outer frame and an inner frame, wherein an outer wing door and an inner wing door which are arranged side by side from outside to inside are arranged at the handrail entrance of the inner frame, a safety limiting block is arranged on the inner wall of the inner frame and below the inner wing door and is arranged on a fixed seat through a return spring, and the upper plane of the safety limiting block and the contact part of the upper plane of the safety limiting block and the lower end part of the inner wing door are in a taper shape from outside to inside.

The outer frame is connected with the inner frame through an energy storage fastener, and the inner frame is of a split structure and is connected through a clamping strip buckle.

After the structure is adopted, through the design of the inner door and the outer door of the outer wing door and the inner wing door and the configuration of the safety limiting block, if the outer wing door and the inner wing door are directly pressed on the outer wing door, the outer wing door and the inner wing door cannot be opened, and objects cannot enter the handrail entrance; if the inner wing door is pressed strongly, the lower end part of the inner wing door is scratched in an arc shape on the upper plane of the safety limiting block by the pressing force, the safety limiting block is enabled to compress the return spring downwards, the inner wing door is opened, the outer wing door is also opened at the same time, the escalator emergency stop switch can be immediately triggered to enable the escalator to stop suddenly, even if an object enters the handrail inlet, the object can be initially blocked by the outer wing door and can be treated in time, no danger is caused, and particularly, the personal safety is effectively protected.

Detailed Description

The invention is described in further detail below with reference to the figures and embodiments.

Referring to fig. 1, 2 and 3, the handrail entrance safety protection device applied to the escalator system comprises an outer frame 1 (made of metal material) and an inner frame 2 (made of plastic material), wherein an outer flap door 4 (a large door, an outer door) and an inner flap door 5 (a small door, an inner door, and a handrail just passing through) are arranged at a handrail entrance 11 (through a common door pin 3) of the inner frame 2 side by side from outside to inside, a safety limit block 6 is arranged on the inner wall of the inner frame 2 and below the inner flap door 5, the safety limit block 6 is arranged on a fixed seat 8 (also arranged on the inner frame 2) through a return spring 7, and the upper plane of the safety limit block 6 and the contact part of the lower end part of the inner flap door 5 are in a taper shape from outside to inside (gradually) upwards (as shown in fig. 3, so as to block and prevent the inner flap door from being opened easily). Wherein, the outer wing door 4 is protected by the inner wing door 5 from the outside, and the inner wing door 5 is blocked by the outer wing door 4 from the inside.

As shown in fig. 2 and 3, the outer frame 1 and the inner frame 2 are connected by energy storage fasteners 10 (including energy storage screws, gaskets, and lock nuts), and the inner frame 2 is a split structure and is connected by a snap fastener 9, which is convenient for the installation of the inner and outer wing doors. The safety limiting block 6 is designed to be of a T-shaped structure.

According to the invention, through the arrangement of the inner and outer double doors of the outer wing door 4 and the inner wing door 5 in parallel (the two side parts of the inner and outer double doors are both the common door pin 3, the inner core of the outer wing door is larger than that of the inner core of the inner wing door), and the safety limit block 6, if the outer wing door is directly pressed on, the outer wing door and the inner wing door cannot be opened due to the blocking of the inner wing door, and objects cannot enter the handrail inlet (the outer wing door and the inner wing door cannot be easily opened); if the inner wing door is pressed strongly, the lower end part of the inner wing door is pressed downwards in an arc shape on the upper plane of the safety limiting block by the pressing force, so that the safety limiting block downwards compresses the return spring 7, the inner wing door is opened, and the outer wing door is also opened simultaneously (even if the inner wing door is opened by strong impact), at the moment, the connected escalator emergency stop switch can be immediately touched to stop the escalator system suddenly, objects can be initially blocked by the outer wing door even entering the handrail inlet, can be treated in time, cannot cause danger, and particularly effectively protects the personal safety (particularly hands and feet of people from being injured).
