Background
The escalator saves the consumption of people moving among floors and improves the life of people. With the increasing widespread use of escalator, safety is also increasingly emphasized. There is a certain gap between the skirt plate and the steps of the escalator, and when the escalator is operating normally, it may happen that foreign matter enters the gap between the skirt plate and the steps, resulting in dangerous situations. Most of the prior anti-pinch devices of the escalator utilize apron plates arranged between steps to deform to trigger a safety switch, and national standards have strict requirements on the deformation of the apron plates after being stressed, so that the problem of insensitive triggering exists, and safety accidents are easy to cause.
The application therefore aims to achieve a tamper resistant escalator which is trigger-sensitive without the need for an irreversible triggering of the escalator to damage.
Disclosure of Invention

The sliding gap is slightly larger than the anti-clamping plate, and a certain sliding gap is formed between the anti-clamping plate and the anti-clamping plate for the anti-clamping plate to slide. The sliding notch is arranged at the transition position from the horizontal section to the inclined section of the escalator. The step is a region where the step is most likely to cause the intrusion of foreign matter, and most of the pinching accidents occur at this stage, so that a cleat is provided therein. Compared with the traditional method of starting a safety switch through apron board deformation, the anti-clamping plate mode is more sensitive to trigger, and when foreign matters invade between the apron board and the steps, the friction force caused by extrusion of the foreign matters drives the anti-clamping plate to synchronously move along with the steps. The clamping object is driven by the friction force of the anti-clamping plate to move, and the anti-clamping plate overcomes the friction force of the apron supporting plate to move relative to the apron supporting plate. The safety switch is triggered by the relative movement of the anti-splints relative to the apron supporting plate, so that the stop is realized. The mode has the advantages that firstly, triggering is generated by friction, and when a human body is clamped, the anti-clamping plate and the steps are driven to synchronously move, and the anti-clamping plate and the apron plate relatively move. The friction force applied to the human body is smaller, and the tearing injury can be avoided by adjusting the resistance. Secondly, the traditional mode can produce irreversible damage to the apron board, once triggering, the accessory needs to be maintained and replaced. By setting the specific triggering force, the safety switch can be prevented from being sensitive and affecting the normal operation of the escalator. In addition, the anti-splints have small injury to human bodies after triggering, are more sensitive and can not cause injury to people and ladders. The triggering force of each position of the anti-splints is the same, so that the triggering area is enlarged.

The structure realizes that the anti-splints are connected on the apron supporting plate in a sliding way. After the sliding block is placed into the sliding notch, a plurality of clamping blocks are installed through the guide groove. The warped edge interferes with the apron supporting plate in the left-right direction of the escalator. Through the clamp splice, prevent that splint can't deviate from the apron backup pad. The gap between the raised edge and the apron supporting plate plays a role in reducing friction force between the raised edge and the apron supporting plate.

Preferably, the adjusting device comprises an adjusting bolt in threaded connection with the mounting bracket, a locking nut for positioning the adjusting bolt and a limiting nut fixedly connected with the adjusting bolt, a convex point is arranged on the triggering bracket, and an adjusting spring is abutted between the convex point and the limiting nut. The structure plays a role in adjusting the sensitivity of the anti-splints, and the elastic force of the adjusting spring can be changed by adjusting the position of the adjusting bolt, so that the friction force required by triggering is changed. The locking nut is used for limiting the adjusting bolt, and looseness caused by vibration is avoided.

The structure realizes how the anti-clamping plate 4 is connected on the apron supporting plate 2 in a sliding way. After being placed into the sliding notch 3, a plurality of clamping blocks 7 are installed through the guide grooves 5. The raised edge 8 interferes with the apron supporting plate 2 in the left-right direction of the escalator. The clamping-proof plate 4 can not be separated from the apron supporting plate 2 through the clamping blocks 7. The gap between the raised edge 8 and the apron support plate 2 acts to reduce friction therebetween.
As shown in fig. 5 and 6, a trigger bracket 9 is fixedly connected to one surface of the anti-splints 4, which is far away from the apron outer plate 1, a mounting bracket 10 is fixed on the apron support plate 2, a safety switch 6 and an adjusting device are arranged on the mounting bracket 10, an adjusting spring 11 is arranged between the adjusting device and the trigger bracket 9, the mounting bracket 10 is abutted against a contact 12 on the safety switch 6, and an idle stroke is arranged between the contact 12 and the safety switch 6. The arrangement described enables the setting of the safety switch 6 and the installation of the adjusting device. The adjusting device and the anti-clamping plate 4 have certain elastic force, so that the anti-clamping plate 4 is prevented from being too sensitive. As shown in fig. 7, the adjusting device comprises an adjusting bolt 13 screwed on the mounting bracket 10, a locking nut 14 positioned on the adjusting bolt 13, and a limit nut 15 fixedly connected on the adjusting bolt 13, wherein a bump 16 is arranged on the triggering bracket 9, and an adjusting spring 11 is abutted between the bump 16 and the limit nut 15.

The step is a region where the step is most likely to cause the intrusion of foreign matter, and most of the pinching accidents occur at this stage, so that the anti-pinching plate 4 is provided therein. Compared with the traditional method of starting the safety switch 6 through the deformation of the apron board, the mode of triggering the anti-clamping plate 4 is more sensitive, and when foreign matters invade between the apron board and the steps, the friction force caused by the extrusion of the foreign matters drives the anti-clamping plate 4 to synchronously move along with the steps.

The advantage of this approach is that firstly, the triggering is generated by friction, and when the human body is clamped, the anti-clamping plate 4 is driven to move synchronously with the steps and move relatively with the apron. The friction force applied to the human body is smaller, and the tearing injury can be avoided by adjusting the resistance. Secondly, the traditional mode can produce irreversible damage to the apron board, once triggering, the accessory needs to be maintained and replaced. By setting the specific magnitude of the triggering force, the safety switch 6 can be prevented from being sensitive enough to influence the normal operation of the escalator. In conclusion, the anti-splints 4 have small injury to human bodies after triggering, are more sensitive and can not cause injury to people and ladders. The triggering force of each position of the anti-splints 4 is the same, so that the triggering area is enlarged.
Example 2:
the distinguishing technical features of this embodiment from embodiment 1 are that:

The structure serves to reduce friction. When the foreign matter invades, external force is exerted on the anti-clamping plate 4, the anti-clamping plate 4 is attached to the apron supporting plate 2, and the friction force between the anti-clamping plate and the apron supporting plate is large. The application reduces the friction force between the two plates by ventilating between the two plates to form a gas layer between the two plates. Specifically, when the two plates are in the zero position, the blocking blocks 21 of the two air flow channels 19 are not opposite, and the air flow can be normally discharged. When the plates slide relative to each other, the blocking piece 21 is opposite, the end of the vent hole 20 is blocked, and the air flow escapes from the gap between the plates and is discharged from between the plates, so as to generate an air layer. In a normal running state, the air flow passes through the vent hole 20, friction force between the two plates is not influenced, after the sum of static friction force between the anti-clamping plate 4 and the apron supporting plate 2 and friction force of the adjusting spring 11 is reached, the two plates start to move relatively, the static friction force is larger than the dynamic friction force, the friction force between the two plates can be reduced by the action of the air layer, and only the elastic force of the adjusting spring 11 is provided, so that friction force received by an invasive part of a human body is greatly reduced, and larger damage caused by continuous tearing is avoided. The relatively large force during starting also has better sensitivity control, so that the escalator can normally run. The airflow channels 19 are arranged in an array, and the distances between adjacent airflow channels 19 are equal. The structure reduces the uniformity of the air layer and reduces the friction between the two plates. The air outlet of the blower is connected with an air guide pipe which extends into the vent hole 20.
