Detailed Implementation

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0028] In one embodiment, such as Figures 1-4As shown, a railway track crossing device includes a base support component 200, a rotating rod component 300, and two prying structures for prying up the rail body 100. The rotating rod component 300 is rotatably connected to the base support component 200 near its bottom. The two prying structures are located at the bottom of the rotating rod component 300. Each prying structure includes a base support pry bar 400, an inner protective abutment component 500, and a switching adjustment component 600. The base support pry bar 400 is fixed to the bottom of the rotating rod component 300 and can pass through the bottom of the rail body 100. The base support pry bar 400 has a hollow structure. The inner protective abutment component 500 is rotatably located at the end of the base support pry bar 400 away from the rotating rod component 300. The switching adjustment component 600 is slidably disposed inside the bottom support pry bar 400. One end of the switching adjustment component 600 is connected to the inner protective abutment component 500, and the other end of the switching adjustment component 600 extends to and is connected to one side of the rotating rod component 300. The switching adjustment component 600 is used to drive the inner protective abutment component 500 to rotate around its connection with the bottom support pry bar 400, so as to switch it between a horizontal state and a vertical state. When the inner protective abutment component 500 is in the vertical state, the inner protective abutment component 500 abuts against the recess on the side wall of the rail body 100. The rotating rod component 300 has an outer buffer elastic part 330 that is arched in a semi-circular state on the side wall facing the inner protective abutment component 500.

[0029] In this embodiment of the invention, railway maintenance personnel place the device on one side of the railway rail. The rail body 100 is supported by sleepers. The bottom support lever 400 passes through the bottom of the rail body 100 between two sleepers. At this time, the inner protective abutment component 500 is at the same level as the bottom support lever 400. The inner protective abutment component 500 and the rotating rod component 300 are respectively located on both sides of the rail body 100. The maintenance personnel operate the switching adjustment component 600 and move the switching adjustment component 600 within the cavity of the bottom support lever 400 to switch the adjustment. The component 600 acts on the inner protective abutment assembly 500 and causes it to rotate, switching the inner protective abutment assembly 500 from a horizontal state to a horizontal state. The inner protective abutment assembly 500 rests against the recessed part of the rail body 100 away from the rotating rod component 300. A prying groove is formed between the outer buffer elastic part 330 and the inner protective abutment assembly 500, and the rail body 100 is placed in the prying groove. The track maintenance worker steps on the bottom support component 200 and holds the top of the rotating rod component 300 with his hands and applies force to it. The rotating rod component 300 and the bottom support... Both the pry bar 400 and the inner protective abutment component 500 rotate around the connection between the rotating rod component 300 and the bottom support component 200, prying upwards the rail body 100. Using leverage to pry up the rail body 100 is relatively labor-saving. Simultaneously, because the rail body 100 is located in the prying groove formed between the outer buffer elastic part 330 and the inner protective abutment component 500, it effectively prevents the rail body 100 from falling off the bottom support pry bar 400 after being pried up, thus avoiding injury to maintenance personnel. Because the outer buffer elastic part 330 is semi-circularly arched, its… When subjected to impact, the outer buffer elastic part 330 can buffer the impact by changing its shape. Therefore, when prying up the rail body 100, the deformation of the outer buffer elastic part 330 can provide a certain buffer space for the vibration of the rail body 100. Furthermore, by applying the prying force in a reciprocating manner, the impact force can be used to reduce the connection force between the rail body 100 and the sleeper. The outer buffer elastic part 330 can buffer the vibration of the rail body 100 from being transmitted to the rotating rod component 300 and the bottom support component 200, thus ensuring the stability of the entire device during the process of prying up the rail body 100.

[0030] In one embodiment, such as Figures 1-5As shown, the inner protective abutment assembly 500 includes an abutment part, an abutment support arm 520, and a switching shaft 530. The switching shaft 530 is rotatably mounted on the end of the bottom support pry bar 400 away from the rotating rod component 300. One end of the abutment support arm 520 is fixedly connected to the switching shaft 530, and the other end is connected to the abutment part. The abutment part contacts the side wall of the rail body 100 away from the rotating rod component 300 in an elastic pressing manner. The switching shaft 530 is provided with a switching connection part 540, and the switching connection part 540 is connected to the switching adjustment component 600. In this embodiment of the invention, the cutting... The adjustment component 600 moves within the base support lever 400 to act on the switching connection part 540. The switching connection part 540 drives the switching shaft 530 to rotate. The supporting arm 520 moves with the switching shaft 530 to switch between horizontal and vertical states. This ensures that the supporting arm 520 and the supporting part do not interfere with the rail body 100 when the base support lever 400 passes through the bottom of the rail body 100. When the rail body 100 is pried up, the supporting arm 520 and the supporting part prevent the rail body 100 from detaching from the front end of the base support lever 400.

[0031] In one embodiment, such as Figures 1-5 As shown, the switching connection part 540 is a gear component, and the switching adjustment part 600 includes a switching action rod 610 and an adjusting screw part 640. The switching action rod 610 is disposed inside the bottom support pry bar 400 and can slide within it. A switching rack 620 is provided at the end of the switching action rod 610 facing the inner protective support assembly 500, and the switching rack 620 meshes with the switching connection part 540. The other end of the switching action rod 610 is provided with a tail helical part 630, and the tail helical part 630 extends to the side of the rotating rod component 300. The adjusting screw part 640 is rotatably mounted on the rotating rod part. The adjusting screw portion 640 is spirally inserted through the tail screw portion 630 on the side wall of component 300. In this embodiment of the invention, the end of the adjusting screw portion 640 has a handwheel. The maintenance personnel turn the handwheel at the end of the adjusting screw portion 640 to make it rotate. The adjusting screw portion 640 causes the switching action rod 610 to move along the length direction of the bottom support pry bar 400 through its own rotation and its cooperation with the tail screw portion 630. The switching rack 620 moves with the switching action rod 610 and drives the switching shaft 530 to rotate through its meshing with the switching connection portion 540, thereby causing the support arm 520 and the support portion to rotate.

[0032] In one embodiment, such as Figures 1-5As shown, the supporting part includes a housing part 510 and a supporting plate 550. The side of the housing part 510 away from the rail body 100 is fixedly connected to the end of the supporting arm 520. The supporting plate 550 is provided on the end face of the housing part 510 facing the rail body 100, and a through rod 552 is provided on the supporting plate 550. The end of the through rod 552 away from the supporting plate 550 passes through the housing part 510 and extends to the back of the housing part 510. The end of the through rod 552 away from the supporting plate 550 is provided with a tail plate part 553. The tail plate part 553 is connected to the housing part 510. The back of 10 is connected by a retaining spring portion 554; in this embodiment of the invention, when the retaining portion contacts the recessed part of the side wall of the rail body 100, the retaining plate 550 is in direct contact with the recessed part of the side wall of the rail body 100, and the retaining spring portion 554 is always in a stretched state and has the tendency to push the through rod 552 and the tail plate portion 553 toward the rail body 100, so that the retaining plate 550 always has pressure against the side wall of the rail body 100, which not only leaves space for the vibration of the rail body 100, but also plays a role in buffering the vibration of the rail body 100.

[0033] In one embodiment, such as Figures 1-5 As shown, the through rod 552 is also provided with a cone block 551, and the side of the cone block 551 facing the tail plate 553 is inclined. Side-pressing movable members 560 are provided on both the upper and lower side walls of the housing 510. One end of the side-pressing movable member 560 extends into the housing 510 and is provided with an inner wedge block 562. The inner wedge block 562 contacts the inclined surface of the cone block 551. The other end of the side-pressing movable member 560 is provided with a top block 561, and the top block 561 is connected to the outer wall of the housing 510 by a tensioning spring 563. In this embodiment of the invention, when the abutment... When the plate 550 abuts against the recessed part of the side wall of the rail body 100, the rail body 100 applies a pushing force to the abutting plate 550 so that the abutting plate 550 moves toward the tail plate part 553. The through rod 552 and the cone block 551 move with the abutting plate 550. The inclined surface of the cone block 551 pushes the inner wedge block 562 laterally by contacting the inner wedge block 562. The inner wedge block 562 is subjected to force and acts on the top block 561 through the side pressing movable member 560. The top block 561 can abut against the side wall of the recessed part to avoid the rail body 100 from vibrating too much up and down and to prevent it from falling off the top side of the abutting part.

[0034] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the lever assembly 300 includes two lever frames 310 and a handle portion 320 located on top of the lever frames 310. The handle portion 320 is located between the two lever frames 310 and its end is fixedly connected to them. Each lever frame 310 corresponds to one of the bottom support levers 400. The bottom support assembly 200 includes a base portion 210 and two rotating seats 220. The two rotating seats 220 are symmetrically arranged on the base portion 210 and are rotatably connected to the sides of the two lever frames 310 respectively. The base portion 210 also has... A ground-penetrating unit 230 is provided that can penetrate the ground. In this embodiment of the invention, the maintenance personnel hold the handle 320 and apply force to it. The handle 320 is subjected to force and drives the lever frame 310 to rotate around its connection with the rotating seat 220. At this time, the base 210 is pressed and applies pressure to the ground. The bottom of the ground-penetrating unit 230 can penetrate the ground, which can effectively ensure the stability of the bottom support component 200 and prevent the bottom support component 200 from moving horizontally when the rail body 100 is pried up, which would cause the entire device to become unstable and overturn.

[0035] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the base portion 210 is provided with two upright members 240, and the top of the upright member 240 has an upper plate portion 270. The ground-penetrating unit 230 includes a spike mounting plate 231 and two connecting arms 234. The spike mounting plate 231 is located on the side of the base portion 210, and the end face of the spike mounting plate 231 facing the ground has multiple spike members 232. One end of each of the two connecting arms 234 is slidably mounted on the two upright members 240, and the other end of the connecting arms 234 is connected to the spike mounting plate 234. 1. Fixed connection: The portion of the connecting arm 234 connected to the upright member 240 is connected to the upper plate portion 270 via a pull-out spring member 260. The base portion 210 is also provided with a stepping part 250, which is connected to the spike rod mounting plate 231. When the stepping part 250 moves towards the rail body 100 on the base portion 210, it acts on the spike rod mounting plate 231, causing it to move downwards along the upright member 240. In this embodiment of the invention, in the initial state, the pull-out spring... When the spring member 260 is in a stretched state, pulling out the spring member 260 allows the connecting arm 234 to be pulled upwards, making the spike mounting plate 231 flush with the base portion 210. When the maintenance personnel pry up the rail body 100 using the rotating rod component 300, the bottom support pry bar 400, and the inner protective abutment component 500, the maintenance personnel step on the foot pedal 250 and move it towards the ground-penetrating unit 230. The foot pedal 250 acts on the spike mounting plate 231 and moves it downwards, thus causing the spike mounting plate 231 to move downwards. It can penetrate the ground, effectively restricting the horizontal movement of the spike mounting plate 231 and the base part 210. At the same time, the worker's feet are pressed against the stepping part 250 and the base part 210, further increasing the stability of the entire device. After the worker's feet are removed from the stepping part 250, the stepping part 250 no longer restricts the upward movement of the spike mounting plate 231. Under the elastic force of the spring member 260 being pulled out and restoring its deformation, the spike mounting plate 231 moves back and the spike member 232 is removed from the ground. The entire device can be quickly transported or moved.

[0036] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the upper surface of the base portion 210 has at least one guide groove. The stepping portion 250 includes a push plate 251 and a stepping plate portion 252. The bottom of the push plate 251 has at least one slider 253 that slides with the guide groove. The stepping plate portion 252 is located at the end of the push plate 251 away from the ground-penetrating unit 230. The end of the push plate 251 facing the ground-penetrating unit 230 has an inclined push head 254. The spike mounting plate 231 is provided with an upper wedge block 233, and the upper wedge block 233 abuts against the inclined surface of the push plate 251. In this embodiment of the invention, the worker steps on the stepping plate portion 252 and pushes the push plate 251 towards the ground. When the surface-piercing unit 230 moves, the inclined jacking head 254 at the front end of the jacking plate 251 contacts the inclined surface of the upper wedge block 233, which can push the upper wedge block 233 and the spike rod mounting plate 231 downward. The spike rod 232 follows the spike rod mounting plate 231 downward and pierces the ground to ensure the stability of the entire device when prying up the rail body 100. When the slider 253 moves to the end of the guide groove, the end wall of the guide groove can block the movement of the slider 253 and the jacking plate 251. After the spike rod 232 pierces the ground, the maintenance personnel only need to step on the foot plate 252 to limit the movement of the bottom support component 200, thus ensuring the stability of the device when prying up the rail body 100.

[0037] The above embodiment provides a railway track crossing device, wherein the inner protective abutment component 500 is at the same level as the bottom support lever 400, and the inner protective abutment component 500 and the rotating rod component 300 are respectively located on both sides of the rail body 100; the operator operates the switching adjustment component 600 and causes the switching adjustment component 600 to move in the inner cavity of the bottom support lever 400, the switching adjustment component 600 acts on the inner protective abutment component 500 and causes it to rotate, the inner protective abutment component 500 is... When the horizontal position is switched to the horizontal position, the inner protective abutment component 500 abuts against the recessed part of the rail body 100 away from the rotating rod component 300. A prying groove is formed between the outer buffer elastic part 330 and the inner protective abutment component 500, and the rail body 100 is placed in the prying groove. The worker's feet are on the bottom support component 200, and his hands are on the top of the rotating rod component 300, applying force to it. The rotating rod component 300, the bottom support pry bar 400, and the inner protective abutment component 500 are all around the rotating rod component 300. The connection between the rail body 100 and the bottom support component 200 is rotated and pried upwards. Using leverage, the rail body 100 is pried up with less effort. Furthermore, because the rail body 100 is positioned in the prying groove formed between the outer buffer elastic part 330 and the inner protective abutment component 500, it effectively prevents the rail body 100 from detaching from the bottom support pry bar 400 after being pried up, thus avoiding injury to maintenance personnel. Since the outer buffer elastic part 330 is semi-circularly arched, it changes shape upon impact. The outer buffer elastic part 330 is designed to buffer the impact. Therefore, when the rail body 100 is pried up, the deformation of the outer buffer elastic part 330 can provide a certain buffer space for the vibration of the rail body 100. Furthermore, by applying the prying force in a reciprocating manner, the impact force can be used to reduce the connection force between the rail body 100 and the sleeper. The outer buffer elastic part 330 can also buffer the vibration of the rail body 100 from being transmitted to the rotating rod component 300 and the bottom support component 200, thus ensuring the stability of the entire device during the process of prying up the rail body 100.
