Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety facility technology, and in particular to a section intrusion warning device for a railway platform lifting protection device. Background Technology
[0002] Railway platform lifting safety devices play a safety protection role on railway platforms, preventing passengers from entering dangerous areas while waiting for their trains.
[0003] Publication No. CN211236276U discloses an intelligent intrusion monitoring system for railway platform ends, comprising intrusion detection and alarm devices installed at both ends of the platform and back-end monitoring equipment installed in the control room. The intrusion detection and alarm devices consist of a column and, from top to bottom, a display screen facing the platform, a front-end camera, a scanning radar, a wireless sensor, a speaker, and a rear-end camera installed opposite the front-end camera. The rear-end camera, front-end camera, display screen, scanning radar, speaker, and wireless sensor are electrically connected to the back-end monitoring equipment. This monitoring system is used to monitor dangerous areas and issue warnings upon detecting unauthorized personnel entering, dissuading passengers from leaving. However, it has a drawback: the warning only exists on-site. Considering potential emergencies such as someone jumping onto the tracks, and the warning being canceled after crossing the rope as the person is no longer within the warning area, and requiring on-site personnel to issue emergency notifications, the staff in the back-end control room may not be able to react quickly enough, potentially leading to adverse situations. Utility Model Content
[0004] This invention aims to overcome the shortcomings of the prior art by providing a section intrusion warning device for a railway platform lifting protection device to solve the aforementioned problems.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This railway platform lifting protection device includes a box, a lifting frame that is movably installed in the box, and a rope connected to the lifting frame. The box is also equipped with a display screen, a scanning radar, a wireless sensor, and a speaker from top to bottom. A connecting arm is provided on the part of the rope that is placed in the box. An alarm is provided in the box located on one side of the connecting arm. When the rope is pulled, the connecting arm moves towards the alarm and triggers the alarm mechanism by contacting the alarm.
[0006] Further improvements include a connecting arm comprising a sleeve, a pin, and a retractable slider that can be compressed. The upper part of the sleeve has a passageway for a rope to pass through, and the passageway has an installation channel on the sleeve for the pin to pass through. The lower part has a movable channel for the slider to slide within. The pin is provided with a locking element to prevent it from disengaging from the installation channel. The slider is used to contact the alarm trigger end of the alarm.
[0007] Further improvements include two symmetrically distributed assembly planes on the upper part of the socket, with the caps of the locking element and the pin fitting into the corresponding assembly planes.
[0008] Further improvements include the addition of two symmetrically distributed locking rods on the outer circumference of one end of the pin that protrudes from the installation channel, and a locking channel at the center of the locking component. The locking channel has a first channel section for the pin to pass through and a second channel section for the locking rod to pass through. After the locking rod passes through the second channel section, the locking component is rotated to make the second channel section and the locking rod misaligned.
[0009] Further improvements were made, with the locking bar now angled from the outside in.
[0010] Further improvements include the following: the movable channel has symmetrically distributed guide grooves on both sides at the lower end of the sleeve; a guide rod that is threadedly connected to the slider and prevents the slider from separating from the sleeve moves within the guide groove; a protrusion is provided at one end of the guide groove and on the guide rod; and a spring is provided between the two protrusions.
[0011] The beneficial effects of this utility model are: The alarm of this invention is connected to an alarm system (linked to the monitoring room). A connecting arm is installed on the rope, so that when climbing and pulling the rope, the connecting arm will move along with it, that is, move towards the alarm. Moreover, the distance between the two is short, and the two will make contact the moment they are pulled. After contact, the alarm will immediately trigger the alarm mechanism to quickly notify railway staff to stop the dangerous behavior and also to stop the train from stopping.

Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings: Referring to the attached diagram: This type of railway platform lifting protection device includes a section intrusion warning device, comprising a housing 1, a lifting frame 2 movably installed inside the housing 1, and a rope 3 connected to the lifting frame 2. The housing 1 is also equipped with a top-down display screen 4, a scanning radar 5, a wireless sensor 6, and a speaker 7. A connecting arm 9 is installed on the portion of the rope 3 inside the housing 1. An alarm 8 is installed inside the housing 1 on one side of the connecting arm 9. When the rope 3 is pulled, the connecting arm 8 moves towards the alarm 8 and triggers the alarm mechanism of the alarm 8 by contacting it. The principle of this utility model is to use scanning radar 5 and on-site cameras on the platform to monitor whether passengers have entered the restricted area while waiting for the train, and to issue voice warnings through loudspeakers. On-site railway staff can also use voice warnings to dissuade passengers. The alarm 8 is connected to the alarm system (linked to the monitoring room). If a passenger does not heed the warnings for a certain period of time, it will send an alarm to the monitoring room. Upon receiving the alarm signal, the monitoring room will dispatch security personnel to intervene. However, considering the possibility of some dangerous situations, such as someone jumping into the track area, the alarm 8 needs to be triggered immediately. Due to the obstruction of rope 3, climbing requires the use of rope 3. Therefore, a connecting arm 8 is set on rope 3, and the alarm is also set inside the housing 1 and located on one side of the connecting arm 8. When rope 3 is pulled, the connecting arm 8 will move along with it, that is, move closer to the alarm 8. Moreover, the distance between the two is short, and the two will make contact at the moment of being pulled. After contact, the alarm 8 will immediately trigger the alarm mechanism to quickly notify railway staff to stop the dangerous behavior.
[0014] The connecting arm 9 includes a sleeve 91, a pin 92, and a retractable slider 93. The upper part of the sleeve 91 has a passageway 911 for the rope 3 to pass through, and the passageway 911 has an installation channel for the pin 92 to pass through. The lower part has a movable channel 913 for the slider 93 to slide within. The pin 92 is provided with a locking piece 10 to prevent it from disengaging from the installation channel. The slider 93 is used to contact the alarm trigger end of the alarm 8. The sleeve 91 is used to connect to the rope 3, and the pin 92 is locked with the locking piece 10 to prevent the sleeve 91 from shifting position on the rope 3. The slider 93 is used to contact the alarm 8, and the length of the slider 93 is greater than the length of the sleeve 91 to achieve quick contact. The retractability is taken into account that the force converted from the weight of the person is large when climbing, and the retraction can reduce the force, thereby also protecting the alarm 8.
[0015] The upper part of the sleeve 91 has two symmetrically distributed assembly planes 911. The caps of the locking member 10 and the pin 92 are in contact with the corresponding assembly planes 914. The arrangement of the assembly planes 914 provides a large contact area, so the caps of the locking member 10 and the pin 92 can be in complete contact with the assembly planes 914. This also ensures the stability of the locking member 10 and the pin 92 on the sleeve 91.
[0016] Two symmetrically distributed locking rods 921 are provided on the outer circumference of one end of the pin 92 that protrudes from the installation channel. A locking channel 101 is provided at the center of the locking member 10. The locking channel 101 has a first channel section 1011 for the pin 92 to pass through and a second channel section 1012 for the locking rods 921 to pass through. After the locking rods 921 pass through the second channel section 1012, the locking member 10 is rotated so that the second channel section 1012 and the locking rods 921 are misaligned. After locking and engaging with the locking member 10, the locking member 10 is prevented from disengaging from the pin 92. That is, when the locking member 10 is engaged with the pin 92, the locking rod 921 and the pin 92 pass together through the first channel section 1011 and the second channel section 1012 of the locking member 10. After passing through, the locking member 10 is rotated so that the second channel section 1012 and the locking rod 921 are misaligned, thus preventing the locking rod 921 from passing through the second channel section 1012. At the same time, the locking rod 921 also abuts against the end face of the locking member 10.
[0017] The locking rod 921 is inclined from the outside to the inside, that is, the through hole on the rope 3 through which the pin 92 passes is tapered, that is, the entrance end of the through hole is larger, so that the pin 92 can enter quickly and avoid getting stuck during installation.
[0018] The movable channel 913 has symmetrically distributed guide grooves 9131 on both sides of the lower part of the sleeve 91. A guide rod 931, which is threadedly connected to the slider 93 and prevents the slider 93 from separating from the sleeve 91, moves within the guide groove 9131. A protrusion 20 is provided on one end of the guide groove 9131 and on the guide rod 931. A spring 30 is provided between the two protrusions 20. This arrangement allows the slider 93 to slide and also reset itself. The combination of the guide rod 931 and the guide groove 9131 not only confines the slider 93 in the movable channel 913, but also provides guidance for movement. The spring 30 is compressed and deformed when the slider 93 contacts the alarm 8, and after release, the slider 93 resets itself due to its elasticity. The two protrusions 20 ensure the stable installation of the spring 30.
[0019] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
