Abstract
Description
Technical Field
[0001] This invention relates to the field of escalator anti-pinch sensing and positioning technology, specifically to a positioning device for an escalator side anti-pinch sensing structure. Background Technology
[0002] Escalators are widely used in various buildings today, especially in shopping malls, train stations, and subway stations where people frequently go up and down stairs. Escalators greatly facilitate people's travel. In these high-traffic environments, escalators bear a heavy workload every day, and since everyone's safety awareness varies, it is essential to implement efficient and reliable safety measures for escalators.
[0003] Current escalators have a relative displacement between the skirt panel and the steps, preventing them from being fully assembled and leaving a gap. This gap presents a risk of pinching. Existing technologies typically install brush mechanisms between the skirt panel and the steps to prevent people from touching the escalator edge and getting pinched. However, shopping malls and similar venues often have many children who might playfully stick their feet through the brush, or adults might unintentionally place items (such as luggage or packages) or their feet under the brush, still posing a risk of pinching. Furthermore, escalators lack a location warning system to detect potential dangers before they occur. Early detection and location of these dangers would significantly alert people to move away, preventing pinching. Therefore, to address these issues, it is necessary to invent a positioning device for an anti-pinch sensor structure on the side of the escalator. Summary of the Invention
[0004] The purpose of this invention is to provide a positioning device for an escalator side anti-pinch sensing structure in order to solve the problems mentioned above.

[0007] A piston plate is fixedly installed on the outer side of the side plate. Multiple sets of piston cylinders are fixedly installed on the top of the piston plate. A push-pull plate is fixedly installed at the bottom of the T-shaped rod. An insert rod is fixedly installed at the bottom of the push-pull plate.

Multiple sets of piston two are slidably installed inside the piston plate. A moving rod inserted into the inner end of the piston two is fixedly connected to the inner end of the piston plate. A roller two is rotatably installed at the inner end of the moving rod.
[0008] In a preferred embodiment of the invention, a small gap is left between the side plates on both sides and the contact points of the steps, so they do not fit together.
[0009] In a preferred embodiment of the invention, a strip is fixedly installed on the left side of the side plate, and a groove adapted to the strip is provided on the right side of the side plate, with bolt holes provided at the positions of both the strip and the groove.
[0010] In a preferred embodiment of the invention, the partition is located above the steps, and the inner end of the partition is provided with closely spaced brushes that are inclined toward the steps.
[0011] In a preferred embodiment of the invention, a slot adapted to the detection rod is provided in the diaphragm, and the insertion end of the top of the detection rod is connected to the slot by a spring.
[0012] In a preferred embodiment of the invention, the outer side of the middle plate is rotatably connected to the turntable via a bearing, and the rotational power of the turntable is generated by a drive motor at the inner end of the turntable.
[0013] In a preferred embodiment of the invention, the straight section at the top of the T-shaped rod is provided with a transverse sliding groove adapted to the linkage rod, and the linkage rod is slidably installed in the transverse sliding groove.
[0014] In a preferred embodiment of the invention, the piston plate is located on the outer side of the side plate, above the top of the step, and both the piston plate and the piston cylinder have piston chambers, which are interconnected by a pipe.
[0015] In a preferred embodiment of the invention, the inner side of the side plate, above the step, has a movable groove for accommodating the movement of the second roller.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0017] 1. In this invention, by setting multiple sets of side plates located on both sides of the steps, and simultaneously setting a detection rod on the inner side of the side plates, when a passenger's body part or a passenger's belongings pass through the brush and reach the dangerous area below the crossbar during the forward movement of the steps, the roller one below the detection rod installed at the bottom of the crossbar will roll over the object as the steps move. At this time, the roller one will drive the detection rod to move upward and compress the spring a certain distance. During this process, the magnetic rod at the top of the detection rod will move upward and approach the proximity switch on the inner side of the side plate, thereby activating the positioning light and horn on the inner side of the side plate. The positioning light is responsible for lighting up to indicate and locate the area of the side plate where an object has entered the dangerous area edge of the gap between the side plate and the steps, while the horn will play a warning sound to inform the object to move away from the bottom of the crossbar and remove it from the brush. This design can provide early warning and location before the possible trapping risk occurs, playing an effective early warning and protection role.
[0018] 2. In this invention, by setting a middle plate, the drive motor is started to drive the turntable to rotate, which in turn drives the linkage rod to move circumferentially. At this time, because the T-shaped rod is guided and limited by the guide sleeve, and the linkage rod slides within the straight section of the top of the T-shaped rod, the linkage rod can compress and drive the T-shaped rod to move vertically up and down when it moves circumferentially. Therefore, during the turntable's clockwise rotation, the T-shaped rod completes a vertical movement first down and then up, eventually returning to the origin. Based on this, by setting a moving rod, when the proximity switch detects the upward displacement of the magnetic rod, it indicates that an object has entered the danger zone below the partition. At this time, according to the above-mentioned functional principle that the T-shaped rod completes a vertical movement first down and then up and eventually returns to the origin when the turntable rotates clockwise once. The drive motor is started, which drives the turntable to rotate. This causes the bottom end of the T-shaped rod to push and pull the insert rod downwards and then upwards, creating a state of positive pressure followed by negative pressure inside the piston cylinder. Since the piston plate and the piston chamber inside the piston cylinder are connected by a pipe, the piston in the piston plate will first drive the moving rod to push the roller two towards the middle of the step, thus pushing out the object that has passed under the crossbar to eliminate the danger. After the object is pushed out, the roller two on the moving rod will return to its original position under the pull of the piston two. In this design, since the power for the roller two to push the object away from the danger zone is from air pressure, it has a certain degree of buffering, thus avoiding injury caused by hard pushing.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] The following will combine Figures 1-6 A detailed description is provided of a positioning device for an anti-pinch sensing structure on the side of an escalator according to an embodiment of the present invention.
[0028] Example:
[0029] Reference Figure 1 , 23, 4, A positioning device for an anti-pinch sensing structure on the side of an escalator includes a step 1. Multiple sets of interlocking side plates 2 are provided on both sides of the step 1. A small gap is left between the side plates 2 and the step 1, preventing them from fitting together. A strip 3 is fixedly installed on the left side of the side plate 2, and a groove 4 adapted to the strip 3 is provided on the right side of the side plate 2. Bolt holes are provided at the positions of both the strip 3 and the groove 4. A transverse partition 5 is fixedly installed on the inner side of the side plate 2, located above the step 1. The inner end of the partition 5 is provided with brushes 6 that are inclined towards the step 1 and are densely distributed. A detection rod 7 is inserted and installed on the lower inner left side of the partition 5. A slot adapted to the detection rod 7 is opened in the partition 5. The insertion end of the top of the detection rod 7 is connected to the slot through a spring. A roller 8 is rotatably installed at the bottom of the detection rod 7. A magnetic rod 9 inserted into the top of the partition 5 is fixedly installed at the top of the detection rod 7. A proximity switch 10, a horn 11 and a positioning light 12 are fixedly installed on the inner side of the side plate 2 above the partition 5.
[0030] By setting multiple sets of side plates 2 on both sides of the step 1, and installing detection rods 7 on the inner side of the side plates 2, when a passenger's body part or belongings pass through the brush 6 and reach the danger zone below the crossbar 5 during the forward movement of the step 1, the roller 8 below the detection rod 7 installed at the bottom of the crossbar 5 will roll over the object as the step 1 moves, causing the roller 8 to push the detection rod 7 upwards, compressing the spring and moving it a certain distance. During this process, the magnet at the top of the detection rod 7... The lever 9 moves upwards towards the proximity switch 10 on the inner side of the side panel 2, thereby activating the positioning light 12 and the horn 11 on the inner side of the side panel 2. The positioning light 12 illuminates to indicate and locate the edge of the dangerous area between the side panel 2 and the step 1, while the horn 11 plays a warning sound, informing the user to remove the object from under the crossbar 5 and away from the brush 6. This design can provide early warning and location before the possible clamping risk occurs, playing an effective early warning and protection role.
[0031] Reference Figure 1 , 2 5. A middle plate 13 is fixedly installed on the outer side of the side plate 2. A turntable 14 is rotatably installed on the outer side of the middle plate 13. The outer side of the middle plate 13 is rotatably connected to the turntable 14 through a bearing. The rotation power of the turntable 14 comes from the drive motor at the inner end of the turntable 14. A pair of guide sleeves 15 are fixedly installed on the outer side of the middle plate 13. A T-shaped rod 16 is inserted and installed on the guide sleeve 15. A linkage rod 17 is fixedly installed on the outer side of the turntable 14, sliding on the straight section at the top of the T-shaped rod 16. A transverse sliding groove adapted to the linkage rod 17 is opened on the straight section at the top of the T-shaped rod 16, and the linkage rod 17 is slidably installed in the transverse sliding groove.
[0032] By setting the middle plate 13, the drive motor is started to drive the turntable 14 to rotate, which in turn drives the linkage rod 17 to move circumferentially. At this time, since the T-shaped rod 16 is guided and limited by the guide sleeve 15, and the linkage rod 17 slides within the straight section of the top of the T-shaped rod 16, the linkage rod 17 can squeeze and drive the T-shaped rod 16 to move up and down in a straight line when it moves circumferentially. Therefore, during the clockwise rotation of the turntable 14, the T-shaped rod 16 completes the straight line movement of first down and then up and finally returns to the origin.
[0033] Reference Figure 1 , 2 3, 4, 5, 6. A piston plate 19 is fixedly installed on the outer side of the side plate 2. Multiple sets of piston cylinders 20 are fixedly installed on the top of the piston plate 19. The piston plate 19 is located on the outer side of the side plate 2 above the top of the step 1. Both the piston plate 19 and the piston cylinders 20 have piston chambers, and the piston chambers in the piston plate 19 and the piston cylinders 20 are interconnected through pipes. A push-pull plate 21 is fixedly installed at the bottom of the T-shaped rod 16. An insert rod 22 is fixedly installed at the bottom of the push-pull plate 21. A piston 1 23 is slidably installed in the piston cylinder 20, and the bottom end of the insert rod 22 is fixedly connected to the piston 1 23. Multiple sets of piston 24 are slidably installed in the piston plate 19. A moving rod 25 inserted into the inner end of the piston 24 is fixedly connected to the inner end of the piston plate 19. A roller 27 is rotatably installed at the inner end of the moving rod 25. An movable groove 26 for accommodating the movement of the roller 27 is opened on the inner side of the side plate 2 above the step 1.
[0034] By setting the shift rod 25, when the proximity switch 10 detects the upward displacement of the magnetic rod 9, it indicates that an object has entered the danger zone below the partition 5. At this time, based on the functional principle that the T-shaped rod 16 completes a linear movement from bottom to top and finally returns to the origin after the turntable 14 rotates clockwise once, the drive motor is started to drive the turntable 14 to rotate. This causes the bottom end of the T-shaped rod 16 to drive the push-pull plate 21 to push and pull the insertion rod 22 from bottom to top. This causes the insertion rod 22 to drive the piston 23 to generate a state of positive pressure followed by negative pressure in the piston cylinder 20. Due to the piston plate 19 The piston chamber inside the piston cylinder 20 is connected to the piston chamber through a pipe. During this process, the piston 24 inside the piston plate 19 will first drive the shift rod 25 to push the roller 27 towards the middle of the step 1, thereby pushing out the object that has passed under the cross plate 5 to eliminate the danger. After the object is pushed out, the roller 27 on the shift rod 25 will return to its original position under the pull of the piston 24. In this design, since the power of the roller 27 to push the object away from the danger zone comes from air pressure, it has a certain buffering effect, thereby avoiding the injury caused by hard pushing.
[0035] The implementation principle of the positioning device embodiment of the escalator side anti-pinch sensing structure of this application is as follows:
[0036] First, by setting multiple sets of side plates 2 on both sides of the step 1, and simultaneously installing detection rods 7 on the inner side of the side plates 2, when a passenger's body part or belongings pass through the brush 6 and reach the danger zone below the crossbar 5 during the forward movement of the step 1, the roller 8 below the detection rod 7, which is inserted and installed at the bottom of the crossbar 5, will roll over the object as the step 1 moves, causing the roller 8 to push the detection rod 7 upwards, compressing the spring and moving it a certain distance. During this process, the top of the detection rod 7... The magnetic rod 9 moves upward and approaches the proximity switch 10 on the inner side of the side plate 2, thereby activating the positioning light 12 and the horn 11 on the inner side of the side plate 2. The positioning light 12 illuminates to indicate and locate the edge of the dangerous area between the side plate 2 and the step 1, while the horn 11 plays a warning sound to inform that the object should be removed from the brush 6 away from the bottom of the crossbar 5. This design can provide early warning and location before the possible clamping risk occurs, playing an effective early warning and protection role.
[0037] Furthermore, by setting the middle plate 13, the drive motor is started to drive the turntable 14 to rotate, which in turn drives the linkage rod 17 to move circumferentially. At this time, since the T-shaped rod 16 is guided and limited by the guide sleeve 15, and the linkage rod 17 slides within the straight section of the top of the T-shaped rod 16, the linkage rod 17 can compress and drive the T-shaped rod 16 to move vertically in a straight line when it moves circumferentially. Therefore, during the clockwise rotation of the turntable 14, the T-shaped rod 16 completes a downward and then upward linear movement and finally returns to the origin. Based on this, by setting the moving rod 25, when the proximity switch 10 detects the upward displacement of the magnetic rod 9, it indicates that an object has entered the danger zone below the partition 5. At this time, according to the functional principle that the T-shaped rod 16 completes a downward and then upward linear movement and finally returns to the origin when the turntable 14 rotates clockwise, the drive motor is started. The motor drives the turntable 14 to rotate, which in turn causes the bottom end of the T-shaped rod 16 to push and pull the push-pull plate 21 downward and then upward, thus pushing and pulling the insertion rod 22. This causes the insertion rod 22 to drive the piston 23 to generate a state of positive pressure followed by negative pressure in the piston cylinder 20. Since the piston plate 19 and the piston chamber in the piston cylinder 20 are connected to each other through pipes, the piston 24 in the piston plate 19 will first drive the shift rod 25 to push the roller 27 towards the middle of the step 1, thereby pushing out the object that has passed under the crossbar 5 to eliminate the danger. After the object has been pushed out, the roller 27 on the shift rod 25 will return to its original position under the pull of the piston 24. In this design, since the power of the roller 27 to push the object away from the danger zone comes from air pressure, it has a certain buffering effect, thus avoiding the injury caused by hard pushing.
