[0037] The present utility model will be further described below in conjunction with the drawings.

[0038] A turnout is a track connection device that enables rolling stock to switch from one track to another. It is also one of the weak links in the track and is usually laid in large quantities at stations and marshalling yards. When cleaning and maintaining railway turnouts, an anti-extrusion device is usually placed between the rail and the switch rail to prevent the turnout from accidentally operating and squeezing equipment and operating personnel. At present, the anti-extrusion device in the railway industry is generally a wooden safety hammer. When cleaning and maintaining railway turnouts, the wooden safety hammer is placed on the slide plate of the turnout. However, during the operation, it is found that the wooden safety hammer is not stable and can only be placed on the flat surface of the slide plate. During the operation, the wooden safety hammer needs to be moved multiple times, and the wooden safety hammer has a single function and cannot play a warning and protective role.

[0039] Embodiment 1

[0040] As Figure 1 shown, to solve the above technical problems, the embodiment of the present application provides a turnout anti-extrusion structure, which includes a hammer head 10, a hammer body 20, and an alarm device 30; one end of the hammer head 10 is provided with a connection component 110 to connect the hammer head 10 to the stock rail of the turnout, and the other end of the hammer head 10 is provided with an alarm switch 120; the hammer body 20 is arranged on the side surface of the hammer head 10; the alarm device 30 is arranged in the hammer head 10, and the alarm device 30 is electrically connected to the alarm switch 120 to make the alarm device 30 emit an alarm when the switch rail of the turnout moves and touches the alarm switch 120.

[0041] As can be seen from the above, by setting the connection component 110, the hammer head 10 can be installed on the stock rail of the turnout, improving the stability of the anti-extrusion structure and preventing the anti-extrusion structure from being blown down by strong winds, etc. Compared with the existing safety hammer, which is limited by the slide plate of the turnout and can only be placed on the flat surface of the slide plate, the present utility model changes the placement method of the traditional safety hammer and can be unrestricted by the placement position. By setting the alarm switch 120 at the other end of the hammer head 10, when the switch rail moves relative to the stock rail due to accidental operation of the turnout, the alarm switch 120 is touched to trigger the alarm device 30 to emit an alarm, thereby playing a warning and protective role, reminding the operating personnel that the turnout has had an accidental operation at this time, and the operating personnel need to stop the operation and evacuate the scene, effectively protecting the operating safety of the operating personnel.

[0042] It should be noted that the turnout includes a switch, and the switch includes a switch rail, a stock rail, and a switching mechanism. The switch rail is connected to the switching mechanism through a switch rod. By operating the switching mechanism, the switch rail can be driven to move relative to the stock rail, thereby changing the position of the switch rail and determining the opening direction of the turnout; therefore, when the turnout has an accidental operation, the switching mechanism will drive the switch rail to move.

[0043] It should also be noted that the hammer head 10 can be in the shape of a cube, and the specific dimensions of the hammer head 10 are set according to actual needs; for example, the hammer head 10 can be 150mm x 100mm x 80mm. In addition, the hammer body 20 is perpendicular to the side surface of the hammer head 10.

[0044] It should also be noted that the alarm switch 120 is in a normally open state, and the alarm switch 120 is a push-button switch. When the switch rail moves and touches the alarm switch 120, the alarm switch 120 is pressed to close, thereby connecting the alarm device 30 and causing the alarm device 30 to emit an alarm sound.

[0045] Embodiment 2

[0046] As Figure 1 shown, the switch anti-extrusion structure includes a hammer head 10, a hammer body 20, and an alarm device 30; a connecting component 110 is provided at one end of the hammer head 10 to connect the hammer head 10 to the stock rail of the switch, and an alarm switch 120 is provided at the other end of the hammer head 10; the hammer body 20 is provided on the side surface of the hammer head 10; the alarm device 30 is provided in the hammer head 10, and the alarm device 30 is electrically connected to the alarm switch 120 to cause the alarm device 30 to emit an alarm when the switch rail of the switch moves and touches the alarm switch 120.

[0047] As can be seen from the above, by providing the connecting component 110, the hammer head 10 can be installed on the stock rail of the switch, improving the stability of the anti-extrusion structure and preventing the anti-extrusion structure from being blown down by strong winds or the like. Compared with the existing safety hammers that are restricted by the switch slide plate and can only be placed in the plane position of the slide plate, the present invention changes the placement method of the traditional safety hammer and can be unrestricted by the placement position. By providing the alarm switch 120 at the other end of the hammer head 10, when the switch rail moves relative to the stock rail during a switch misoperation and touches the alarm switch 120, the alarm device 30 is triggered to emit an alarm, thereby playing a warning and protective role, reminding the operating personnel that a switch misoperation has occurred at this time, and the operating personnel need to stop the operation and evacuate the site, effectively protecting the operating safety of the operating personnel.

[0048] It should be noted that the switch includes a switch machine, and the switch machine includes a switch rail, a stock rail, and a switching mechanism. The switch rail is connected to the switching mechanism through a switch rod. By operating the switching mechanism, the switch rail can be driven to move relative to the stock rail, thereby changing the position of the switch rail and determining the opening direction of the switch; therefore, when a switch misoperation occurs, the switching mechanism will drive the switch rail to move.

[0049] It should also be noted that the hammer head 10 can be in the shape of a cube, and the specific dimensions of the hammer head 10 are set according to actual needs; for example, the hammer head 10 can be 150mm x 100mm x 80mm. In addition, the hammer body 20 is perpendicular to the side surface of the hammer head 10.

[0050] It should also be noted that the alarm switch 120 is in a normally open state, and the alarm switch 120 is a push-type switch. When the switch rail moves and touches the alarm switch 120, the alarm switch 120 is pressed to close, thereby connecting the alarm device 30 and causing the alarm device 30 to emit an alarm sound.

[0051] As Figure 1 shown, in some embodiments, the connecting component 110 includes a magnetic member 1101 and an insulating film 1102; the magnetic member 1101 is disposed at one end of the hammer head 10; the insulating film 1102 is disposed at one end of the magnetic member 1101 away from the hammer head 10.

[0052] By providing the magnetic member 1101 for magnetic adsorption connection with the stock rail, the connection method is simple and convenient, not only stable, but also can move within a large range without being restricted by the switch slide plate, greatly improving the practicability and reliability; by providing the insulating film 1102 to protect the magnetic member 1101, preventing the magnetic member 1101 from being damaged by bumping during use, and at the same time playing an insulating role to improve safety.

[0053] It should be noted that the magnetic member 1101 is a magnet.

[0054] In some embodiments, the thickness of the insulating film 1102 is 2 mm.

[0055] By limiting the thickness of the insulating film 1102, it is ensured that the insulating film 1102 can not only play a protective role, but also be magnetically connected to the rail, thereby avoiding the thickness of the insulating film 1102 being too thin to play a protective role, and also avoiding the thickness of the insulating film 1102 being too thick, so that the magnetic member 1101 cannot be magnetically connected to the rail.

[0056] As Figure 1 shown, in some embodiments, the turnout anti-squeezing structure further includes a power supply device 40, and the power supply device 40 includes a battery 410 and a charging interface 420; the battery 410 is disposed in the hammer body 20 and is electrically connected to the alarm device 30; the charging interface 420 is disposed on the hammer body 20 and is electrically connected to the battery 410.

[0057] By providing the battery 410 to supply power to the turnout anti-squeezing structure, the charging interface 420 is used to charge the battery 410. In addition, by disposing the battery 410 in the hammer body 20, the internal space of the hammer body 20 is reasonably utilized, and there is no need to separately provide an installation space for the battery 410.

[0058] It should be noted that the battery 410 is a rechargeable lithium battery 410, and the rechargeable lithium battery 410 has the advantages of high energy density, long cycle life, low self-discharge rate, no memory effect, fast charge and discharge ability, environmental protection and safety.

[0059] It should also be noted that the charging interface 420 is a 5V, 500MA interface.

[0060] like Figure 1 , Figure 2 As shown, in some embodiments, the alarm device 30 includes an alarm speaker 310 electrically connected to a battery 410 ; wherein the alarm switch 120 is electrically connected to the alarm speaker 310 and the battery 410 to control the operation of the alarm speaker 310 .

[0061] like Figure 1 , Figure 2 As shown, in some embodiments, the turnout anti-extrusion structure further includes a warning device 50 disposed on the top of the hammer body 20 , the warning device 50 is electrically connected to the power supply device 40 , and the warning device 50 is connected in parallel with the alarm device 30 .

[0062] By arranging the warning device 50 in parallel with the alarm device 30 , flexibility and practicality are improved, and the warning device 50 and the alarm device 30 can work independently.

[0063] like Figure 1 , Figure 2 As shown, in some embodiments, the warning device 50 includes a lamp post 510 and a warning light 520; the lamp post 510 is arranged on the top of the hammer body 20; the warning light 520 is arranged on the lamp post 510, and the lamp post 510 is arranged inside the lamp post 510 and is electrically connected to the battery 410.

[0064] Warning light 520 not only serves as emergency lighting but also as a warning, especially at night. Nighttime operations often involve emergency situations such as breakdowns and snow removal, putting workers under intense stress. Anti-crush structures are difficult to spot in low visibility and can easily be left behind at the turnout. Therefore, the warning light 520 serves as a reminder that someone is working there and effectively prevents the anti-crush structure from being left behind at the turnout operation site, potentially preventing accidents.

[0065] It should be noted that the lamp post 510 is a transparent lamp post 510 .

[0066] like Figure 1 , Figure 2 As shown, in some embodiments, the warning light 520 includes a flash light 5201 and a highlight light 5202 ; the flash light 5201 is disposed inside the lamp post 510 ; and the highlight light 5202 is disposed on the top of the lamp post 510 .

[0067] The warning effect is enhanced by setting a flash light 5201, and the flash light 5201 is used to clearly remind people that someone is working here; the lighting effect is improved by using a strong light 5202, and strong light is provided for emergency lighting.

[0068] It should be noted that the flash lamp 5201 is an LED lamp. Additionally, in order to enhance the warning effect at night, the flash lamp 5201 can be a dual-color LED lamp. For example, the flash lamp 5201 is a red and blue dual-color flash lamp 5201.

[0069] As Figure 1 , Figure 2 shown, in some embodiments, the flash lamp 5201 is connected in parallel with the spotlight 5202. The warning device 50 further includes a first switch 530 and a second switch 540. The first switch 530 is electrically connected to the flash lamp 5201 and the battery 410 to control the operation of the flash lamp 5201. The second switch 540 is electrically connected to the spotlight 5202 and the battery 410 to control the operation of the spotlight 5202.

[0070] By connecting the flash lamp 5201 in parallel with the spotlight 5202, the flexibility and practicality of the warning device 50 are improved, enabling the flash lamp 5201 and the spotlight 5202 to operate independently.

[0071] It should be noted that the first switch 530 and the second switch 540 are normally open switches.

[0072] It should also be noted that a shunt switch can be used instead of the first switch 530 and the second switch 540. The flash lamp 5201 and the spotlight 5202 are respectively connected to the shunt switch, enabling the warning device 50 to have multiple operating states. For example, a two-way three-section shunt switch is used instead of the first switch 530 and the second switch 540. The flash lamp 5201 and the spotlight 5202 are respectively connected to the two-way three-section shunt switch. The two-way three-section switch is used to control the flash lamp and the spotlight 5202, enabling the warning device 50 to have three operating states: only the flash lamp 5201 is on, only the spotlight 5202 is on, and both the flash lamp 5201 and the spotlight 5202 are on simultaneously.

[0073] In some embodiments, the hammer head 10 is a plastic hammer head, and the hammer body 20 is a plastic hammer body.

[0074] It should be noted that the hammer head 10 is a nylon hammer head. The nylon block has the advantages of super wear resistance, good toughness, good insulation, light weight, corrosion resistance, and good mechanical strength, solving the problems of the existing wooden hammers being easily cracked, damaged, low in strength, unstable, and having a low safety factor due to environmental factors such as temperature, humidity, thermal expansion and contraction, usage frequency, and human external force.

[0075] It should also be noted that the hammer body 20 is a PVC hammer body, and an insulating rubber layer is provided on the outer wall of the hammer body 20, which has good strength and anti-slip properties and is convenient to carry.

[0076] Although the present utility model has been described with reference to the preferred embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
