Description

Technical Field

[0001] The utility model belongs to the technical field of sound and light alarm equipment, and in particular relates to an adjustable sound and light alarm equipment for rail transportation. Background Art

[0002] In rail transit systems, sound and light alarms can send clear warning signals to staff and passengers. When a train is about to enter or exit a station, the sound and light alarm equipment detects the approach of the train and sounds an alarm to remind passengers on the platform to pay attention to safety and not to approach the edge of the track. At track construction sites, sound and light alarm equipment can warn construction workers and passers-by to pay attention to the construction area to avoid accidents. The adjustable sound and light alarm can flexibly adjust the installation height, angle and direction according to different usage scenarios and needs.

[0003] After searching, a Chinese utility model patent (authorization announcement number CN218198302U) disclosed a rail transit train approach alarm sensor device, which fixes the rail holder by rotating the fixing screw through the fixing nut. After the fixation is completed, the mounting groove on the base is sleeved on the fixing screw. After the sleeve is completed, the washer is sleeved on the top of the fixing screw, and then the nut is screwed on to complete the installation of the shell, shell cover, approach alarm sensor and base. When installing the sound and light alarm, it is necessary to screw multiple sets of screws and nuts to install and fix the sound and light alarm. This makes it necessary to screw multiple sets of nuts to disassemble the sound and light alarm for maintenance or replacement later, which makes the installation and disassembly of the sound and light alarm more troublesome, greatly reducing the efficiency of disassembly and replacement.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-5The adjustable sound and light alarm device for rail transit shown includes:

[0024] A mounting plate 1 is provided with a mounting base 2 on the top of the mounting plate 1, a sound and light alarm 3 is fixed in the mounting base 2, an alarm light 4 is provided on the top of the sound and light alarm 3, and a fixing assembly for fixing the sound and light alarm 3 is provided in the mounting base 2, and the positive and negative threaded screws 5 of the fixing assembly are rotated to drive the two groups of clamping blocks 6 on the surfaces of the positive and negative threaded screws 5 to move, so that the two groups of clamping blocks 6 are close to each other to clamp and fix the sound and light alarm 3;

[0025] The cleaning component is arranged inside the top of the sound and light alarm 3. The alarm light 4 moves in the multiple groups of arc blocks 7 of the cleaning component, so that the alarm light 4 is wiped by the cleaning sponge 8 on the surface of the arc block 7 when it moves up and down.

[0026] The fixing assembly includes a slider 9 and a self-locking hand crank 10. The forward and reverse screw rods 5 are rotatably connected to the mounting base 2. The two sets of blocks 6 are connected to the surface of the forward and reverse screw rods 5 through the screw nut and the other end of the block 6 is movable through the opening on the surface of the bottom plate 11 inside the mounting base 2. The bottom of the block 6 is slidably connected to the slide groove provided in the mounting base 2 through the slider 9. The self-locking hand crank 10 is connected to one end of the forward and reverse screw rods 5 located outside the mounting base 2. When the self-locking hand crank 10 is screwed, the forward and reverse screw rods 5 can be driven to rotate and the self-locking hand crank 10 has a self-locking function. When the self-locking hand crank 10 is rotated to the specified position, the rod body will automatically lock to avoid the self-locking hand crank 10 from loosening after screwing, causing unstable clamping.

[0027] The top of the mounting base 2 is provided with a mounting opening 12 , and after the bottom of the sound and light alarm 3 is inserted into the mounting opening 12 , the sound and light alarm 3 is fixed by engaging with the card slots 13 on the surface of the sound and light alarm 3 through two groups of card blocks 6 .

[0028] The cleaning component includes a cylinder 14 and a movable strip 15. The cylinder 14 is arranged in the sound and light alarm 3 and the piston rod of the cylinder 14 is connected to the movable strip 15. The bottom of the alarm light 4 is connected to the movable strip 15 and the two ends of the movable strip 15 are slidably connected to the slide groove provided in the sound and light alarm 3. A plurality of movable grooves 16 are provided in the top of the sound and light alarm 3. The arc block 7 is slidably connected in the movable groove 16. The cylinder 14 is a micro cylinder, which has a fast response speed and occupies a small space.

[0029] A fixed plate 17 is provided in the movable groove 16, and a guide rod 18 is slidably passed through the middle of the fixed plate 17. One end of the guide rod 18 is connected to the arc block 7. A slide plate 19 is fixedly sleeved on the surface of the guide rod 18, and both ends of the slide plate 19 are slidably connected to the slide grooves provided in the movable groove 16. The guide rod 18 can guide the moving direction of the arc block 7 when the arc block 7 moves, thereby enhancing the stability of the movement of the arc block 7.

[0030] The surface of the guide rod 18 is covered with a spring 20, and the two ends of the spring 20 are respectively connected to the fixed plate 17 and the slide plate 19. When the arc block 7 moves, the spring 20 can be squeezed, and under the action of the elastic force of the spring 20, the side of the arc block 7 with the cleaning sponge 8 is in contact with the protective shell of the alarm light 4.

[0031] When installing the sound and light alarm 3 of this adjustable sound and light alarm device for rail transit, the mounting plate 1 can be screwed and fixed to the edge of the track by bolts, and the bottom of the sound and light alarm 3 can be inserted into the mounting port 12 of the mounting base 2 and contacted with the bottom plate 11, and then the self-locking hand crank 10 is screwed to drive the positive and negative threaded screws 5 to rotate so that the two groups of card blocks 6 move on the surface of the positive and negative threaded screws 5 and approach each other. The card blocks 6 are engaged with the card grooves 13 on the surface of the sound and light alarm 3 under continuous movement, thereby fixing the sound and light alarm 3. When the sound and light alarm 3 needs to be disassembled, it is only necessary to screw the self-locking hand crank 10 in the opposite direction to make the two groups of card blocks 6 move away from each other and disengage from the card grooves 13, thereby completing the disassembly, which is more convenient and greatly improves the efficiency of disassembly and installation of the sound and light alarm 3.

[0032] When it is necessary to clean the protective shell on the surface of the alarm light 4, the cylinder 14 can be started to work, and the piston rod of the cylinder 14 pushes the movable strip 15 to move upward and drives the alarm light 4 to move, and the top of the alarm light 4 passes through the multiple groups of arc blocks 7, and the dust on the surface of the protective shell of the alarm light 4 is wiped by the cleaning sponge 8 on the surface of the arc block 7. Under the continuous movement of the alarm light 4, the protective shell of the alarm light 4 squeezes the arc block 7 outward so that the arc block 7 moves into the movable groove 16 through the guide rod 18 and squeezes the spring 20. Under the action of the elastic force of the spring 20, the side of the arc block 7 with the cleaning sponge 8 is in contact with the protective shell of the alarm light 4, so that the dust covered on the surface of the protective shell can be wiped clean under the continuous movement of the alarm light 4, thereby avoiding the problem that the alarm light 4 is located next to a track with people coming and going for a long time, so that a large amount of dust will adhere to the surface of the protective shell, which affects the light transmittance of the protective shell and cannot transmit light and signals well.
