Technical Field

The invention relates to an escalator protection device, in particular to a sliding type anti-pinch escalator.

Background

The staircase saves the consumption of people moving between floors and improves the life of people. With the increasing wide application of escalators, the safety is also increasingly emphasized by people. There is a certain gap between the skirt panel and the steps of the escalator, and when the escalator is normally operated, it may occur that foreign materials enter the gap between the skirt panel and the steps, thereby causing a dangerous situation to occur. Most of the existing escalator anti-pinch devices trigger a safety switch by utilizing the deformation of an apron plate arranged between steps, and the national standard has strict requirements on the deformation of the stressed apron plate, so that the problem of insensitive triggering exists, and safety accidents are easily caused.

The invention is therefore based on the object of providing an anti-jamming escalator which is sensitive to triggering and does not require irreversible triggering which damages the escalator.

Disclosure of Invention

The invention overcomes the defects that the existing escalator anti-pinch triggering structure is an irreversible triggering structure, is limited by the strength requirement of an elevator and has slow triggering, and provides a sliding type anti-pinch escalator which can realize a more sensitive anti-pinch function, can prevent the anti-pinch triggering contact from being reused and is beneficial to rapidly restoring the normal operation of the escalator.

In order to solve the technical problems, the invention adopts the following technical scheme:

the utility model provides a staircase is prevented pressing from both sides by gliding formula, the apron board of staircase is equipped with the breach of sliding including the apron planking that is close to the step and the apron backup pad of keeping away from the step on the apron planking, be equipped with the pinch-proof plate on the breach of sliding, be equipped with the guide way that corresponds with the pinch-proof plate in the apron backup pad, the pinch-proof plate passes through guide way sliding connection in the apron backup pad, pinch-proof plate elastic connection has safety switch.

The sliding gap is slightly larger than the anti-pinch plate, and the anti-pinch plate generate a certain sliding gap for sliding. The sliding notch is arranged at the transition position from the horizontal section to the inclined section of the escalator. The steps have height variation differences at the positions, are areas most prone to foreign matter intrusion, and most clamping accidents occur at the stage, so that the clamping prevention plate is arranged. Compare the traditional way of starting safety switch through the skirtboard deformation, the pinch-proof plate mode in this application triggers more sensitively, invades between skirtboard and the step when the foreign matter, will drive pinch-proof plate along with step simultaneous movement because of the frictional force that its extrusion brought. The object to be clamped is driven by the friction force of the anti-pinch plate to move, and the anti-pinch 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-pinch plate relative to the apron supporting plate, so that the machine is stopped. The mode has the advantages that firstly, the trigger is generated by friction force, and when a human body is clamped, the anti-pinch plate is driven to synchronously move with the step and relatively move with the apron plate. The friction force on the human body is smaller, and the tearing injury can be avoided by adjusting the resistance. Secondly, the traditional way can produce irreversible damage to the apron board, once triggered, the accessory needs to be repaired and replaced. Through setting for the specific size of triggering strength, can avoid safety switch too sensitive, influence the normal work of staircase. In conclusion, the anti-pinch plate has small injury to the human body after being triggered, is more sensitive and can not cause injury to people and ladders. The force triggered by each position of the anti-pinch plate is the same, so that the triggering area is enlarged.

Preferably, one side of the anti-pinch plate close to the apron supporting plate is fixedly connected with a plurality of clamping blocks, the clamping blocks extend into the guide grooves, the clamping blocks extend towards the raised edges of the apron supporting plate, and gaps are formed between the raised edges and the apron supporting plate. How sliding connection of pinch-off preventive plate has been realized in the apron backup pad to the structure. After the clamping block is placed in the sliding notch, a plurality of clamping blocks are installed through the guide groove. The raised edges interfere with the apron supporting plates in the left and right directions of the escalator. Through the clamp splice, the pinch-proof plate can't deviate from the apron backup pad. The clearance between the raised edge and the apron supporting plate plays a role in reducing the friction force between the raised edge and the apron supporting plate.

Preferably, one side of the anti-pinch plate, which is far away from the apron outer plate, is fixedly connected with a trigger support, a mounting support is fixed on the apron support plate, a safety switch and an adjusting device are arranged on the mounting support, an adjusting spring is arranged between the adjusting device and the trigger support, the mounting support is abutted to a contact on the safety switch, and an idle stroke is arranged between the contact and the safety switch. The structure realizes the setting of the safety switch and the installation of the adjusting device. Certain elasticity is provided between the adjusting device and the anti-pinch plate, so that the anti-pinch plate is prevented from being too sensitive.

Preferably, the adjusting device comprises an adjusting bolt in threaded connection with the mounting support, a locking nut for positioning the adjusting bolt and a limiting nut fixedly connected with the adjusting bolt, the triggering support is provided with a salient point, and an adjusting spring is abutted between the salient point and the limiting nut. The structure plays the effect of adjustment pinch-proof plate sensitivity, through adjustment adjusting bolt's position, can change adjusting spring's elasticity size, changes the frictional force that triggers needs. The locking nut is used for limiting the adjusting bolt, and looseness caused by vibration is avoided.

Preferably, the apron supporting plate is provided with an apron plate reinforcing rib, and the mounting bracket is fixedly connected to the apron plate reinforcing rib through a fastener.

Preferably, the trigger support is L-shaped, a notch is formed in the short edge of the trigger support, a trigger reinforcing rib is arranged on the trigger support, and the trigger reinforcing rib is inserted into the notch to form a convex point. The convex points play a role in positioning the adjusting spring, and the adjusting spring is prevented from deviating and falling.

Preferably, one side of the apron supporting plate facing the anti-pinch plate and one side of the anti-pinch plate facing the apron supporting plate are provided with corresponding airflow channels, the airflow channels are matched to form an air vent, the apron supporting plate is further provided with a blower, the blower ventilates the air vent, the tail end of the airflow channel is provided with a blocking block, when the anti-pinch plate slides, the blocking blocks on the anti-pinch plate and the apron supporting plate are matched to block the air vent, and airflow blown out by the blower passes through the anti-pinch plate and the apron supporting plate and reduces friction force between the two plates.

The structure serves to reduce friction. When the foreign matter invaded, external force was applyed on the pinch-proof plate, and the pinch-proof plate laminating is on the apron backup pad, and frictional force between the two is great. The application makes the one deck gas layer of formation between the two through ventilating between two boards, reduces the frictional force between the two. Specifically, when the two plates are in zero positions, the blocking blocks of the two airflow channels are not opposite, and airflow can be discharged normally. When the two plates slide relatively, the blocking blocks are opposite, the tail ends of the vent holes are blocked, airflow escapes from the gap between the two plates and is discharged from the gap between the two plates, and an air layer is generated. Under normal operating condition, the air current passes through in the air vent to do not influence the frictional force between the two boards, after reaching the static frictional force between pinch-proof plate and the apron backup pad and the frictional force of adjusting spring, two boards begin relative motion, the more kinetic friction power of static frictional force is bigger, frictional force between two boards also can receive the gas layer effect and diminish, only has adjusting spring's elasticity effect, so the frictional force that the invasion part of human body received reduces greatly, avoid lasting the tearing and lead to the fact great damage. And relatively large force during starting also has better sensitivity control, so that the escalator can normally run.

Preferably, the gas flow channels are arranged in an array with equal spacing between adjacent gas flow channels. The structure reduces the uniformity of the gas layer and reduces the friction between the two plates.

Preferably, the air outlet of the blower is connected with an air guide pipe, and the air guide pipe extends into the vent hole.

Compared with the prior art, the invention has the beneficial effects that: (1) the triggering of the anti-pinch plate is triggered relatively to the traditional deformation, and the triggering force of each position is the same, so that the triggering area is enlarged; (2) the anti-pinch plate is triggered more sensitively, and personal injury is reduced; (3) the anti-pinch plate is simple to reset after being triggered, so that the escalator is prevented from being injured, and the restarting work of the escalator can be quickly recovered.

the utility model provides a staircase is prevented pressing from both sides by gliding formula, as shown in fig. 1 to 3, the apron board of staircase is equipped with the breach 3 that slides on the apron planking 1 including the apron planking 1 that is close to the step and the apron backup pad 2 of keeping away from the step, be equipped with on the breach 3 that slides and prevent pinch plate 4, be equipped with the guide way 5 that corresponds with prevent pinch plate 4 on the apron backup pad 2, prevent pinch plate 4 through 5 sliding connection of guide way on apron backup pad 2.

As shown in fig. 4, one side of the anti-pinch plate 4 close to the apron supporting plate 2 is fixedly connected with a plurality of clamping blocks 7, the clamping blocks 7 extend into the guide grooves 5, the clamping blocks 7 extend towards the raised edges 8 of the apron supporting plate 2, and gaps are arranged between the raised edges 8 and the apron supporting plate 2. The structure realizes how the anti-pinch plate 4 is connected on the apron supporting plate 2 in a sliding way. After the sliding block is placed in the sliding gap 3, a plurality of clamping blocks 7 are installed through the guide grooves 5. The raised edge 8 interferes with the apron support plate 2 in the left and right directions of the escalator. Through the clamping block 7, the anti-pinch plate 4 cannot be separated from the apron supporting plate 2. The clearance between the raised edge 8 and the apron support plate 2 plays a role in reducing the friction force between the raised edge and the apron support plate.

As shown in fig. 5 and 6, one side fixedly connected with that the anti-pinch plate 4 is far away from the apron outer plate 1 triggers the support 9, the apron support plate 2 is fixed with a mounting support 10, the mounting support 10 is provided with a safety switch 6 and an adjusting device, an adjusting spring 11 is arranged between the adjusting device and the triggering support 9, the mounting support 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. Said construction enables the setting of the safety switch 6 and the mounting of the adjusting device. Have certain elasticity between adjusting device and the pinch-off preventive plate 4, avoid pinch-off preventive plate 4 too sensitive.

The structure plays the effect of adjustment pinch-proof plate 4 sensitivity, through adjustment adjusting bolt 13's position, can change adjusting spring 11's elasticity size, changes the frictional force that triggers the needs. The locking nut 14 is used for limiting the adjusting bolt 13 and avoiding looseness caused by vibration. An apron plate reinforcing rib 17 is arranged on the apron supporting plate 2, and the mounting bracket 10 is fixedly connected to the apron plate reinforcing rib 17 through a fastener. The trigger support 9 is L-shaped, a notch is formed in the short edge of the trigger support 9, a trigger reinforcing rib 18 is arranged on the trigger support 9, and the trigger reinforcing rib 18 is inserted into the notch to form a convex point 16. The convex points 16 play a role in positioning the adjusting spring 11, and prevent the adjusting spring 11 from deviating and falling.

The sliding gap 3 is slightly larger than the anti-pinch plate 4, and the two generate a certain sliding gap for the anti-pinch plate 4 to slide. The sliding notch 3 is arranged at the transition position from the horizontal section to the inclined section of the escalator. The steps have a difference in height at this position, which is the area most likely to cause the intrusion of foreign objects, and most of the clamping accidents occur at this stage, and therefore the anti-pinch plate 4 is provided here. Compare the traditional way of starting safety switch 6 through the skirtboard deformation, the 4 modes of anti-pinch plate in this application trigger more sensitively, invade between skirtboard and the step when the foreign matter, will drive anti-pinch plate 4 along with step simultaneous movement because of the frictional force that its extrusion brought. The object to be clamped is driven by the friction force of the anti-pinch plate 4 to move, and the anti-pinch plate 4 overcomes the friction force of the apron supporting plate 2 to move relative to the apron supporting plate 2. The safety switch 6 is triggered by the relative movement of the apron supporting plate 2 generated by the anti-pinch plate 4, so that the machine is stopped. The advantage of the mode is that firstly, the trigger is generated by friction force, when a human body is clamped, the anti-pinch plate 4 is driven to synchronously move with the step and move relative to the apron plate. The friction force on the human body is smaller, and the tearing injury can be avoided by adjusting the resistance. Secondly, the traditional way can produce irreversible damage to the apron board, once triggered, the accessory needs to be repaired and replaced. By setting the specific size of the triggering force, the situation that the safety switch 6 is too sensitive and influences the normal work of the escalator can be avoided. To sum up, the anti-pinch plate 4 has little harm to the human body after being triggered, is more sensitive and can not cause harm to people and ladders. The triggering force of each position of the anti-pinch plate 4 is the same, so that the triggering area is enlarged.

Example 2:

The structure serves to reduce friction. When the foreign matter invaded, external force was applyed on anti-pinch plate 4, and anti-pinch plate 4 laminating is on apron backup pad 2, and frictional force between the two is great. The application makes the one deck gas layer of formation between the two through ventilating between two boards, reduces the frictional force between the two. Specifically, when the two plates are in the zero position, the blocks 21 of the two airflow channels 19 are not opposite, and the airflow can be discharged normally. When the two plates slide relatively, the blocks 21 are opposite, the tail ends of the vent holes 20 are blocked, and air flow escapes from the gap between the two plates and is discharged from the gap between the two plates to generate an air layer. Under normal operating conditions, the air current passes through in the air vent 20 to do not influence the frictional force between the two boards, after reaching the static frictional force between pinch-proof plate 4 and the apron backup pad 2 and the frictional force of adjusting spring 11 and summing up, two boards begin relative motion, the static frictional force is bigger than the kinetic friction power, frictional force between two boards also can receive the gas layer effect and diminish, only has adjusting spring 11's elasticity effect, so human invasion partial frictional force that receives reduces greatly, avoid lasting the tearing and lead to the fact great damage. And relatively large force during starting also has better sensitivity control, so that the escalator can normally run. The gas flow channels 19 are arranged in an array with equal spacing between adjacent gas flow channels 19. The structure reduces the uniformity of the gas 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.

The above-described embodiments are merely preferred embodiments of the present invention, which is not intended to be limiting in any way, and other variations and modifications are possible without departing from the scope of the invention as set forth in the appended claims.
