[0002] With the rapid development of the domestic economy, urban construction is accelerating, and traffic congestion in cities is serious. In order to ease the pressure of ground traffic and facilitate citizens' travel, major cities have begun to build urban rail transit. With the strong support of local governments for urban rail transit, the urban rail transit network has gradually developed and improved, and has ushered in a networked operation model. At the same time, networked operation has brought many challenges to urban rail transit management, and the pressure on track operation and maintenance is one of them. When a platform screen door fails in rail transit, the protective alarm device is first used to prevent passengers from direct contact with rail transit and tracks.

[0003] However, there are some problems with the prior art: the alarm of the existing protective alarm device is installed on the pole tube by using multiple bolts, and the warning plate is also installed on the frame by using multiple bolts. Therefore, when the alarm and the warning plate need to be disassembled for maintenance, multiple bolts need to be unscrewed one by one, and the operation process is relatively cumbersome. Therefore, we propose a protective alarm device for rail transit operation and maintenance. Utility Model Content

[0023] The staff operates the first buckle assembly 6, and then the first buckle assembly 6 is buckled and fixed on the mounting block 5, so that the alarm 3 is easy to be installed on the rod barrel 1. When the alarm 3 needs to be disassembled for maintenance, the staff re-operates the first buckle assembly 6 so that the alarm 3 can be disassembled from the rod barrel 1, which is convenient for disassembling and maintaining the alarm 3. The staff operates the second buckle assembly 7, and then one end of the connecting block 8 is inserted into the through-slot. After the insertion is completed, the connecting block 8 is fixed in the through-slot by the second buckle assembly 7, so that the warning plate 4 is installed on the mounting frame 2. When the warning plate 4 needs to be disassembled for maintenance, the staff operates the second buckle assembly 7 so that the connecting block 8 is not fixed, and then the warning plate 4 can be disassembled from the mounting frame 2, which is convenient for disassembling and maintaining the warning plate 4. The warning plate 4 is used to warn passers-by to prevent passers-by from approaching, and the alarm 3 is alarmed by sensor induction, which is used to remind passers-by who have not seen the warning plate 4.

[0024] Specifically, the first buckle assembly 6 includes a first fixed frame 601, one end of which is fixedly installed on one end of the alarm 3, and two groups of guide rods 602 are fixedly installed in the first fixed frame 601; two groups of first sliding sleeves 603 are slidably sleeved on the two groups of guide rods 602, and two groups of connecting plates 604 are arranged in the first fixed frame 601, and two groups of mounting holes are opened on the connecting plates 604, and the two groups of mounting holes are respectively fixedly sleeved on the first sliding sleeves 603 of the two groups of guide rods 602; a first reset spring 605 is arranged between the two groups of connecting plates 604, and buckle blocks 606 are fixedly installed on the two groups of connecting plates 604; an insertion groove is opened at one end of the mounting block 5, and the first buckle grooves are opened at the upper and lower ends of the insertion groove, one end of the two groups of connecting plates 604 are inserted into the insertion groove together, and the buckle block 606 is buckled into the first buckle groove.

[0025] The staff member pinches the two groups of connecting plates 604 together, thereby driving the first return spring 605 to compress and drive the first sliding sleeve 603 to slide on the surface of the guide rod 602, and also drives the two groups of buckle blocks 606 to approach each other. After the two groups of connecting plates 604 are pinched together, one end is then inserted into the insertion groove, and at the same time, the buckle block 606 is also driven to be inserted into the insertion groove. After the connection plates 604 are inserted, the two groups of connecting plates 604 are then relaxed. Due to the action of the first return spring 605, the two groups of connecting plates 604 are separated from each other, so that the buckle block 606 is buckled in the first buckle groove, which makes it easy to install the alarm 3 on the rod barrel 1. The staff member pinches the two groups of connecting plates 604 together again, so that the buckle block 606 can be moved out of the first buckle groove, and then the alarm 3 can be removed from the rod barrel 1.

[0026] Furthermore, the first sliding sleeve 603 slides on the surface of the guide rod 602, so that the connecting plate 604 is guided when moving.

[0027] Specifically, the second buckle assembly 7 includes a second fixed frame 701, the lower surface of the second fixed frame 701 is fixedly installed on the upper surface of the cross bar, the upper surface of the second fixed frame 701 is provided with two groups of fixing holes, and the second sliding sleeve 702 is fixedly installed in the two groups of fixing holes, a buckle rod 703 is slidably arranged in the second sliding sleeve 702, and a pull plate 704 is fixedly installed on the upper surface of the buckle rod 703; a second return spring 705 is elastically connected to the lower surface of the pull plate 704, and the lower ends of the two groups of second return springs 705 are jointly fixedly installed on the upper surface of the second fixed frame 701, two groups of insertion holes are provided at the upper end of the insertion slot, two groups of second buckle grooves are provided on the upper surface of the connecting block 8, and the two groups of second buckle grooves are respectively connected to the two groups of insertion holes, and the lower ends of the two groups of buckle rods 703 are respectively inserted through the two groups of insertion holes to the buckle grooves.

[0028] The staff pulls the pull plate 704 upward, thereby driving the second return spring 705 to stretch and drive the buckle rod 703 to slide in the second sliding sleeve 702, and the buckle rod 703 slides in the second sliding sleeve 702, so that the lower end moves from the through slot and the insertion hole to the second fixed frame 701, and moves to the second fixed frame 701 through the buckle rod 703, and then one end of the connecting block 8 is inserted into the through slot, and the two groups of second buckle slots are connected with the two groups of insertion holes respectively. After the connection, the pull plate 704 is then relaxed. Due to the action of the second return spring 705, the lower end of the buckle rod 703 is inserted through the insertion hole to the buckle groove, so that the connecting plate 604 is fixed in the through slot, and the staff disassembles and pulls the pull plate 704, so that the buckle rod 703 can be moved out of the buckle groove, so that the connecting block 8 is not fixed.
