Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a three-way four-way turnout. Background Technology

[0002] A three-way turnout uses a set of switch machines to drive two sets of switch rails to alternately contact or separate from the corresponding stock rails, enabling trains to safely switch between one main line and two sidings. The core logic of the three-way turnout is to use a set of switch machines to control two sets of switch rails in conjunction, and to complete the switching of "main line open - siding closed" or "siding open - main line closed" according to instructions, while always ensuring that only one line is fully connected.

[0003] When switching tracks using existing three-way turnouts, switch machines are used. However, the switch machine's track is relatively complex, the maintenance cost is high, and there are often stones on the platform that are difficult to clean. If not cleaned in time, it will shorten the normal service life of the equipment.

[0004] Therefore, this application provides a three-way four-direction turnout to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a three-way four-direction turnout to solve the problem of switching by using a switch machine. However, the switch machine has a relatively complex track and high maintenance cost. At the same time, there are many stones on the platform, which are difficult to clean. If they are not cleaned in time, the normal service life of the equipment will be shortened.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: The three-way four-way turnout includes a base, a reinforcing plate is installed on the top of the base, a track plate is fixedly connected to the top of the reinforcing plate, a straight turnout is installed on the top of the track plate, a guide rail is provided on the top of the track plate, and a curved turnout is slidably provided on the top of the track plate.

[0007] Optionally, a mudguard is installed in the middle slot of the curved turnout, and a toothed column is fixedly connected in the middle slot of the curved turnout.

[0008] Optionally, the mudguard is positioned above the toothed column, and the number of toothed columns is set to multiple.

[0009] Optionally, a locking plate is movably inserted into the top of the curved turnout, and a gear is installed inside the front end of the base via a servo motor, with the gear column meshing with the gear.

[0010] Optionally, a sealed box is installed at the bottom of the base, and the gear is located inside the sealed box.

[0011] Optionally, a positioning plate is embedded inside the base, and a groove is provided on the top of the positioning plate.

[0012] Optionally, the top height of the locking plate exceeds the horizontal plane of the curved turnout before being inserted into the slide groove, and the two sides of the slide groove are set as inclined surfaces.

[0013] Optionally, an electromagnetic sensor is installed on the bottom inner wall of the positioning plate, and a limit plate is installed on the bottom of the track plate.

[0014] Optionally, a roller is installed at the bottom of the limiting plate, and a shovel plate is installed on one side of the limiting plate.

[0015] Optionally, the number of rollers is set to multiple sets, and the end of the shovel plate is set to be arc-shaped.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects: The above scheme includes the following settings: This utility model replaces the complex switch machine by using a servo motor, gear and toothed column meshing drive, which simplifies the structure and reduces maintenance costs. At the same time, it eliminates the safety hazards caused by turnout misalignment by using a locking plate and an electromagnetic sensor for dual positioning, coupled with remote video confirmation. This utility model features a shovel plate that automatically cleans dust and stones from the guide rail as the turnout moves, preventing jamming and extending the equipment's service life. Rollers assist the turnout's movement, reducing friction and ensuring smooth switching. A reinforcing plate strengthens the stability of the base.

[0017] Compared to traditional three-way turnouts, this invention does not rely on a complex switch machine system. By combining mechanical structure with electromagnetic induction, it achieves precise and automated turnout switching, which not only reduces the initial investment and subsequent maintenance costs of the equipment, but also reduces the probability of failures caused by track aging and foreign object obstruction.

[0018] The inclined surface of the locking plate and the slide groove of this utility model can be matched to lock the turnout without additional power when positioning. The signal feedback of the electromagnetic sensor and the remote video monitoring form a dual verification mechanism to eliminate the risk of train operation caused by misoperation or positioning deviation. The reinforcing plate is made of titanium alloy, which enhances the load-bearing capacity of the base while taking into account the need for lightweight, and is suitable for the passage needs of trains of different tonnages.

[0028] like Figures 1 to 6 As shown, an embodiment of this utility model provides a three-way four-way turnout, including: a base 1, a reinforcing plate 2 installed on the top of the base 1, a track plate 3 fixedly connected to the top of the reinforcing plate 2, a straight turnout 4 installed on the top of the track plate 3, a guide rail 5 opened on the top of the track plate 3, and a curved turnout 6 slidably arranged on the top of the track plate 3.

[0029] like Figures 1 to 6 As shown, a mudguard 7 is installed in the middle slot of the curved turnout 6, and a toothed column 8 is fixedly connected in the middle slot of the curved turnout 6. The mudguard 7 is positioned above the toothed column 8, and there are multiple toothed columns 8. A locking plate 9 is movably inserted into the top of the curved turnout 6. A gear 10 is installed inside the front end of the base 1 through a servo motor. The toothed column 8 is meshed with the gear 10. A sealing box 11 is installed at the bottom of the base 1. The sealing box 11 has a moisture-proof and dust-proof function for the gear 10 and the servo motor. The gear 10 is located inside the sealing box 11. The sealing box 11 protects the gear 10 and the servo motor. The mudguard 7 shields the toothed column, improving the dust and moisture resistance of the components.

[0030] like Figures 1 to 6 As shown, a positioning plate 12 is embedded inside the base 1. A groove 13 is provided on the top of the positioning plate 12. The top height of the locking plate 9 exceeds the horizontal plane of the curved turnout 6 before being inserted into the groove 13. The two sides of the groove 13 are set as inclined surfaces. An electromagnetic sensor 14 is installed on the bottom inner wall of the positioning plate 12. A limit plate 15 is installed on the bottom of the track plate 3. A roller 16 is installed on the bottom of the limit plate 15. A scraper 17 is installed on one side of the limit plate 15. The number of rollers 16 is set to multiple sets. The end of the scraper 17 is set as an arc shape, which can efficiently remove debris in the guide rail without scratching the surface of the guide rail, ensuring the smooth movement of the turnout.

[0031] The working principle of the technical solution provided by this utility model is as follows: When a train is about to arrive and the position of the curved turnout 6 needs to be adjusted, the motor built into the base 1 is activated to drive the gear 10 to rotate. The gear 10 then drives the toothed column 8 at the front end of the mudguard 7, which is meshed with it, to rotate. The toothed column 8 then moves the curved turnout 6 to the left until the locking plate 9 slides through the top of the positioning plate 12 and inserts into the slide groove 13 along the inclined surface on one side of the slide groove 13, touching the electromagnetic sensor 14. Only then will the electromagnetic sensor 14 send a signal to the electrically connected signal transmitter, which sends a signal to the backend to notify the train that it can pass through the turnout. As the curved turnout 6 moves to the left, the titanium alloy roller 16 at the bottom of the limiting plate 15 rolls and moves horizontally within the guide rail 5 to limit the movement and reduce friction. At the same time, the scraper plate 17 removes dust from the guide rail 5 to prevent jamming.

[0032] The locking plate 9 slides on the inner wall of the curved turnout 6 and falls naturally under gravity. Only when the locking plate 9 is fully inserted into the slide groove 13, and the staff confirms by observing the top of the locking plate 9 and the electromagnetic sensor 14 at the bottom of the locking plate 9 being touched through an external remote video, can it be determined whether the curved turnout 6 is in proper use. Only then can the signal light be turned on to allow the train to enter directly, thus avoiding safety hazards caused by the existing curved turnout 6 malfunctioning due to aging of the track. At the same time, the reinforcing plate 2 is set between the straight turnout 4 and the base 1. It is made of titanium alloy and is responsible for reinforcing the base 1. The mudguard 7 is used to directly shield the tooth column 8 and gear 10 from dust and dirt.
