Description

Technical Field

[0001] The utility model relates to the technical field of railway traffic safety, in particular to a quick-installed detection device for train approach alarm. Background Art

[0002] Railways need to be regularly inspected and maintained during operation. Currently, three protective measures are usually adopted during railway maintenance. The first is manual lookout, with 1-5 safety officers and 1 person in the station dispatching room to understand the train operation plan in real time, notify the site through walkie-talkies, arrange 2 remote lookouts at 2,000 meters each for the construction site, notify the site through walkie-talkies for incoming trains, arrange 2 safety officers at both ends of the construction site, and blow the horn for incoming trains, which causes a large waste of manpower, financial resources and material resources during railway maintenance and increases the labor cost of railway maintenance; the second is to use crossing alarms, which requires laying cables, the equipment is complex and not easy to move, and the installation is cumbersome, which increases the workload and labor intensity of the staff; the third is to receive train signals, which has the problem of inaccurate distance measurement and is prone to maintenance accidents. Therefore, the train approaching voice alarm system came into being. By installing the main body of the equipment 4-8 kilometers in front of the construction site, the construction site personnel can be warned and evacuated more than 2 minutes in advance, which increases the warning distance and time and greatly reduces the labor cost, making the construction site more intelligent and the personnel safer.

[0003] At present, the train approach voice alarm system mainly includes two parts: the train approach alarm detection device and the train approach alarm host. When the alarm host receives the train approach information from the detector, it determines that a train has entered the red danger zone and will pose a threat to the green protection zone, and will continue to alarm to remind relevant personnel. When the detector receives the departure information and determines that there is no vehicle in the red zone, the green protection zone is safe and the alarm is automatically lifted. The detector uses a single-point radar. A set of detectors is equipped with two sets of radars with a certain distance in between. When a train enters, the two sets of radars will detect in turn and use solar energy for power supply. However, the existing train approach alarm detection device still has some defects. The radar detector and the solar rack are fastened with too many bolts to the overall bracket, which greatly increases the complexity and time of installation and is not conducive to rapid deployment and maintenance. Based on this, we designed a quick-install train approach alarm detection device. Utility Model Content

[0022] During specific implementation, in order to ensure that the limit plate 102b is more stably located in the slot 102a, a permanent magnet sheet is embedded in the bottom of the slot 102a, and the limit plate 102b includes permanent magnet gaskets 102b-1 arranged on both sides of its lower surface and a handle 102b-2 arranged at its bottom. The permanent magnet gasket 102b-1 and the permanent magnet sheet at the bottom of the slot 102a attract each other. Under the attraction between the permanent magnet gasket 102b-1 and the permanent magnet sheet and the pressing state of the connecting column 103 on the limit plate 102b, the limit plate 102b can be more stably located in the slot 102a.

[0023] In a specific implementation, in order to facilitate the rotation of the connecting column 103 , through openings 102 c are provided on both sides of the top of the concave plate 102 .

[0024] In a specific implementation, in order to prevent the latch 4 from rotating, the handle 5 is arranged in an arc shape matching the connecting column 103 .

[0025] In specific implementation, in order to facilitate compression of the spring 704 when the positioning rod 702 moves, a disc 703 is provided on the outer wall of the positioning rod 702 located in the inner cavity of the hollow cylinder 701. The disc 703 abuts against one end of the spring 704, and the other end of the spring 704 is fixed on the inner wall of the hollow cylinder 701.

[0026] During specific implementation, in order to facilitate the fixation of the positioning rod 702 after being pulled outward, matching threads are provided on one side of the outer wall of the positioning rod 702 located in the inner cavity of the hollow cylinder 701 and on the outer inner wall of the hollow cylinder 701 penetrated by the positioning rod 702. After the positioning rod 702 is pulled outward so that its outer wall threads come into contact with the outer inner wall threads of the hollow cylinder 701, the positioning rod 702 can be rotated to form a threaded connection with the hollow cylinder 701, thereby fixing the positioning rod 702.

[0027] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows:

[0028] When in use, pinch the spring pin 6 inward to retract it into the latch 4, pull the handle 102b-2 to pull the latch 4 out of the connecting column 103, the bottom of the radar detector 3 loses its fixation with the connecting column 103, and the radar detector 3 can be taken out from it to complete the disassembly, and the positioning rod 702 is pulled outward to separate it from the positioning groove 801. After the thread of the outer wall of the positioning rod 702 is connected with the thread of the outer inner wall of the hollow cylinder 701, the positioning rod 702 is rotated to be screwed with the hollow cylinder 701 to achieve the limited fixation of the positioning rod 702. When the positioning rod 702 is loosened, it will not move under the elastic force of the spring 704. At this time, the bracket 8 can be taken out and disassembled together with the photovoltaic panel 9. Since the connecting column 103 and the concave plate 102 are rotatably connected together, the handle 102b-2 is pulled out to pull the limiting plate 102b out of the slot 102a. At this time, the connecting column 103 rotates inward to move closer to the column 1, which can reduce the occupied space of the overall device and facilitate transportation.

[0029] When installation is required, unfold the connecting column 103 again, and reinsert the limiting plate 102b into 102a to limit the connecting column 103, insert the bottom of the radar detector 3 on the connecting column 103, pinch the spring pin 6 inwards and then pass the plug 4 through the connecting column 103 and the radar detector 3. After the plug 4 passes through the connecting column 103, the spring pin 6 pops out and fixes the plug 4 on the connecting column 103. At the same time, the plug 4 fixes the radar detector 3 on the connecting column 103, insert the bracket 8 into the connecting frame 7, rotate the positioning rod 702 so that its thread is disengaged from the thread on the hollow cylinder 701, and under the action of the elastic force of the spring 704, the positioning rod 702 can be driven to move inward and inserted into the positioning groove 801, so that the bracket 8 and the connecting frame 7 can be positioned and fixed, and the installation of the photovoltaic panel 9 is completed.

[0030] The above description of the embodiments is to facilitate ordinary technicians in this technical field to understand and use the utility model. It is obvious that those familiar with the technology in this field can easily make various modifications to the embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the protection scope of the utility model.
