Description

Technical Field

[0001] This utility model belongs to the field of rail transit technology, specifically relating to movable signal lights for rail transit. Background Technology

[0002] In urban three-dimensional transportation systems, the intersections of rail transit and surface transportation are key nodes in traffic management. Some rail transit trains need to cross surface roadways, and in these areas, rail transit traffic lights play an indispensable role. Due to the constant flow of vehicles and pedestrians on surface roads, coupled with the high speed of rail transit trains, any traffic conflicts can easily lead to serious traffic accidents.

[0003] The role of traffic lights in rail transit is crucial. For ground vehicles and pedestrians, the lights, through striking red, yellow, and green color changes and clear text or graphic markings, clearly indicate when they can proceed and when they must stop. For example, when the light is red, ground vehicles must stop behind the safety line, and pedestrians should also stop on the crosswalk to avoid entering the rail transit train's operating area; when the light turns green, it indicates that ground traffic can proceed normally. For rail transit trains, the lights are a vital basis for drivers to judge whether it is safe to pass through the intersection; only when the lights permit can the train safely cross the level crossing. In this way, rail transit traffic lights effectively coordinate the traffic order of ground vehicles and rail transit trains, ensuring the safety of ground vehicles and pedestrians while also ensuring the smooth operation of rail transit trains, greatly reducing the probability of traffic accidents, and guaranteeing the efficient operation of the urban transportation system and the safety of citizens' travel.

[0004] The existing rail transit signal lights are at a fixed height, but the operating environment of rail transit signal lights is complex. The visual height of the train drivers and motor vehicle drivers they face is different, which leads to the signal lights being in the blind spot of some drivers or requiring them to make great efforts to adjust their vision to see them clearly. When the train is traveling at high speed, it is difficult to obtain signal information in a timely and accurate manner, which increases the risk of traffic safety. Utility Model Content

[0005] The purpose of this utility model is to provide a movable signal light for rail transit, which aims to solve the problem that existing rail transit signal lights have a fixed height, but the operating environment of rail transit signal lights is complex, and the visual height of the train driver and the motor vehicle driver is different. As a result, the signal light is in the blind spot of some drivers or they have to make great efforts to adjust their vision to see it. When the train is traveling at high speed, it is difficult to obtain signal information in a timely and accurate manner, which increases the risk of driving safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a movable signal light for rail transit, comprising a signal light body, the bottom surface of which abuts against a base, a column welded to the top surface of the base, a remote control module connected to the top surface of the column by bolts and threads, the remote control module being electrically connected to a motor via a power line, the motor being mounted on the upper surface of the column, the motor shaft being threadedly connected to the transverse end surface of a gear, the other side of the gear being sleeved within a bearing provided on the surface of the column, the gear meshing with a gear plate, the other side of the gear plate being connected to the inner wall surface of the signal light body column, and a slider connected to the other side of the inner wall surface of the signal light body column, the slider being slidably connected within a limiting groove opened on the surface of the column.

[0007] As a preferred embodiment of the movable signal light for rail transit of this utility model, the motor, gear, and toothed plate form a meshing connection structure.

[0008] As a preferred embodiment of the movable signal light for rail transit of this utility model, a "T"-shaped limiting groove is longitudinally formed on the surface of the column away from the gear, and the shape and size of the limiting groove are adapted to the slider.

[0009] As a preferred embodiment of the movable signal light for rail transit of this utility model, a rectangular groove is longitudinally formed at the bottom of the signal light column, and the shape and size of the groove are adapted to the column.

[0010] As a preferred embodiment of the movable signal light for rail transit of this utility model, the base has mounting brackets connected to both sides of the base, a top plate connected to the upper inner wall surface of the mounting brackets, a spring connected to the bottom surface of the top plate, the bottom surface of the spring connected to the top of the base plate, a limiting rod connected to the top surface of the base plate, the upper surface of the limiting rod movably inserted into the surface of the top plate, casters installed on the bottom surface of the base plate, and the surfaces of the rectangular blocks on both sides of the top of the base plate are threadedly connected to the surface of the mounting brackets using screws.

[0011] As a preferred embodiment of the movable signal light for rail transit of this utility model, a rectangular through groove is longitudinally formed on the surface of the top plate, and the shape and size of the through groove are adapted to the rectangular block on the top of the bottom plate. The top plate, spring, bottom plate and limiting rod form an elastic connection structure.

[0012] As a preferred embodiment of the movable signal light for rail transit of this utility model, the rectangular blocks on both sides of the top of the base plate are provided with threaded grooves, and the shape and size of the threaded grooves are adapted to the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the cooperation between the column, remote control module, motor, gear, toothed plate, slider and limit groove, the remote control module starts the motor to drive the gear to rotate according to the actual traffic conditions and the driver's field of vision height required. This causes the meshing toothed plate and the signal light body to be adjusted in height, thereby meeting the needs of drivers at different field of vision heights to drive safely on the track according to the traffic signal lights.

[0015] By utilizing the cooperation between the base, mounting frame, top plate, spring, bottom plate, limit rod, casters, and screw, the height of the casters connected to the traffic light can be adjusted when the traffic light does not need to be moved. The casters are then stored inside the mounting frame. This increases the contact area between the mounting frame and the ground, thereby stabilizing the traffic light and preventing it from tipping over, which could affect the safety of rail transit.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides the following technical solution: a movable signal light for rail transit, including a signal light body 1, the bottom surface of the signal light body 1 abutting against a base 2, a column 3 welded to the top surface of the base 2, a remote control module 4 connected to the top surface of the column 3 by bolt threads, a motor 5 electrically connected to the remote control module 4 by a power line, a surface of the motor 5 mounted on the upper surface of the column 3, a shaft surface of the motor 5 threadedly connected to the transverse end surface of a gear 6, another side surface of the gear 6 sleeved in a bearing provided on the surface of the column 3, a gear plate 7 meshing with the surface of the gear 6, another side surface of the gear plate 7 connected to the inner wall surface of the column of the signal light body 1, a slider 8 connected to the other side surface of the inner wall of the column of the signal light body 1, and a sliding block 8 slidably connected in a limiting groove 9 opened on the surface of the column 3. In this design, the signal light body 1 and the base 2 form a movable arrow signal light body, and a large number of related components are provided in the movable arrow signal light body. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0025] The main model of the mobile arrow traffic light in this solution is: PHYD300-2-J.

[0026] In use: The solar panel on the surface of the base 2 collects solar energy, which is then used to power the signal light body 1 connected above. The signal light body 1 is connected to the signal control system next to the track via a cable, and the status of the main signal equipment is synchronized in real time (such as automatically switching to the mobile signal light to take over the command when the main signal light fails). According to the traffic conditions, the high-brightness LED beads on the surface of the signal light body 1 form arrow patterns (such as left, right, straight, etc.), and the light is focused by an optical lens to ensure that the signal is clearly visible at a distance.

[0027] Preferably, the motor 5, gear 6, and toothed plate 7 form a meshing connection structure.

[0028] In actual use, the starter motor 5 drives the gear 6 to rotate, thereby causing the toothed plate 7 that is meshed with the gear 6 to move upward in parallel.

[0029] Preferably, a "T"-shaped limiting groove 9 is longitudinally formed on the surface of the column 3 away from the gear 6, and the shape and size of the limiting groove 9 are adapted to the slider 8.

[0030] In practical use, when the column of the signal light body 1 is driven to move upward, the slider 8 connected to the other side of the inner wall of the signal light body 1 slides together in the limiting groove 9 opened on the surface of the column 3, so that the signal light body 1 moves upward stably.

[0031] Preferably, a rectangular groove is formed longitudinally at the bottom of the signal light body 1, and the shape and size of the groove are adapted to the column 3.

[0032] In practical use, the groove at the bottom of the signal light body 1 is used to easily fit onto the surface of the column 3, thereby facilitating the adjustment of the height of the signal light body 1 with the cooperation of the remote control module 4 and the motor 5 installed on the column 3.

[0033] Preferably: mounting brackets 10 are connected to both sides of the base 2, the upper inner wall surface of the mounting brackets 10 is connected to the top plate 11, the bottom surface of the top plate 11 is connected to the spring 12, the bottom surface of the spring 12 is connected to the top of the base plate 13, the top surface of the base plate 13 is connected to the limiting rod 14, the upper surface of the limiting rod 14 is movably inserted into the surface of the top plate 11, the bottom surface of the base plate 13 is equipped with casters 15, and the surfaces of the rectangular blocks on both sides of the top of the base plate 13 are threadedly connected to the surface of the mounting brackets 10 using screws 16.

[0034] In practical use, the universal wheels 15 connected to the mounting brackets 10 on both sides of the base 2 can be used to move the base 2 to a suitable position and place it, and move the signal light body 1 to the designated area.

[0035] Preferably, a rectangular through groove is formed longitudinally on the surface of the top plate 11, and the shape and size of the through groove are adapted to the rectangular block on the top of the bottom plate 13. The top plate 11, spring 12, bottom plate 13 and limiting rod 14 form an elastic connection structure.

[0036] In practical use, the caster wheel 15 is driven upward by the spring 12 connected at the top. When the base plate 13 is driven upward by the spring 12, the limiting rod 14 connected at the top slides upward together on the inserted top plate 11, thereby limiting the range of movement of the base plate 13, so that the caster wheel 15 moves away from the ground it is in contact with.

[0037] Preferably, the rectangular blocks on both sides of the top of the base plate 13 have threaded grooves, and the shape and size of the threaded grooves are adapted to the screw 16.

[0038] In practical use, the screw 16, which is threaded between the mounting bracket 10 and the rectangular plate of the base plate 13, is unscrewed, thereby facilitating the adjustment of the height of the caster wheel 15 within the mounting bracket 10 via the elastically connected spring 12.

[0039] Working principle: In the field of rail transit, to meet the needs of placing traffic lights, the universal wheels 15 connected to the mounting brackets 10 on both sides of the base 2 can be used to move the base 2 to the appropriate position. After the traffic light body 1 is moved to the designated area, the screw 16 threaded between the mounting bracket 10 and the rectangular plate of the base plate 13 is unscrewed. This causes the universal wheels 15 threaded to the lower end of the mounting bracket 10 to be driven upward by the spring 12 connected to the top. When the base plate 13 is driven upward by the spring 12, the limiting rod 14 connected to its top slides upward together on the inserted top plate 11, thereby limiting the movement range of the base plate 13. This causes the universal wheels 15 to move away from the ground. At this time, the bottom of the mounting bracket 10 and the base 2 are stably pressed against the ground, providing stable support for the traffic light body 1 above. This prevents the traffic light body 1 from being unstable under the influence of strong winds, which would affect subsequent traffic guidance.

[0040] Simultaneously, when the arrow pattern on the surface of the signal light body 1 changes under the control of the signal control system via the connected cable, the remote control module 4 connects to control the motor 5. After directing the motor vehicle, the motor 5 starts and drives the gear 6 to rotate, thereby causing the toothed plate 7 connected to the gear 6 to move upward in parallel. The movement of the gear 6 causes the column of the connected signal light body 1 to move together. When the column of the signal light body 1 is driven upward, the slider 8 connected to the other side of the inner wall of the main body of the signal light body 1 slides in the limiting groove 9 opened on the surface of the column 3, thereby making the signal light body 1 move upward stably, thereby adjusting the height of the signal light body 1. The height of the signal light body 1 is adjusted in conjunction with the field of vision of the rail transit driver, which facilitates the command of both rail transit and motor vehicles in the application scenario of intersecting.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
