Description

Technical Field

[0001] The present invention relates to the technical field of track structure installation, in particular to a suspension track connection structure. Background Art

[0002] The suspended monorail system is an aerial rail train with tracks above the train, supported in the air by steel or concrete columns. By moving ground traffic into the air, it can alleviate urban traffic problems without the need to expand the city's existing road facilities. Moreover, since it only moves the tracks into the air, rather than lifting the entire road surface into the air like elevated light rail or ride-on monorail, it overcomes the shortcomings of other rail transit systems and has many outstanding features and advantages in construction and operation.

[0003] Suspension track beams typically come in two cross-sections: I-shaped and open-bottomed box-shaped. When using the open-bottomed box-shaped cross-section, webs are used to ensure the stability and integrity of the connection between the track beams. Specifically, the webs are precisely fitted to the inside and outside of the track beam connection line. Through a reliable connection process, the webs and track beams are tightly integrated, effectively transferring loads and ensuring the safety and stability of the suspended track system during operation.

[0004] In the prior art, when two curved webs are used to connect the curves of the track beam, the train's running trajectory changes when passing through the curve and is affected by centrifugal force. This centrifugal force is transmitted through the track beam, thereby exerting greater stress on the outer web. In actual operation, the train frequently passes through curves, and the outer web is prone to deformation due to long-term and continuous exposure to this greater stress. The deformed web will change the geometric shape of the track beam, destroying the smoothness of the track.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0030] like Figures 1 to 8 As shown, a suspension track connection structure of the present invention includes a front track beam 1, a rear track beam 2 is provided on one side of the front track beam 1, and the adjacent cross sections of the front track beam 1 and the rear track beam 2 can be plugged into each other, and the bottoms of the front track beam 1 and the rear track beam 2 are symmetrically fixedly connected with an arc-shaped cross beam 20, and the outer web 7 and the inner web 8 are provided on both sides of the front track beam 1 and the rear track beam 2, respectively. A driving component for driving the outer web 7 and the inner web 8 to move closer to each other is provided between the upper parts of the outer web 7 and the inner web 8, and a positioning component is provided between the lower parts of the outer web 7 and the inner web 8 and the arc-shaped cross beam 20. The positioning component makes the outer web 7 and the inner web 8 fit more firmly to the inner and outer sides of the front track beam 1 and the rear track beam 2, and a reinforcement component for reinforcing the outer web 7 is provided on the outer side of the outer web 7.

[0031] During operation: When the web is connected to the track beam curve, the train will be affected by centrifugal force due to the change of its running trajectory when passing through the curve. The centrifugal force will be transmitted through the track beam, and then exert greater stress on the outer web, which is prone to deformation, affecting the stability and comfort of the train operation; the existing adjacent cross sections of the front track beam 1 and the rear track beam 2 are butted together to form a stable track beam structure as a whole, and a butt seam is formed at the cross section. The drive assembly can be placed above the front track beam 1 and the rear track beam 2, and the outer web 7 and the inner web 8 are kept located on the outside and inside of the connection between the front track beam 1 and the rear track beam 2 respectively. The outer web 7 and the inner web 8 are both arc-shaped, and the degree of arc is determined by the front track beam 1 and the rear track beam 2. The arc angle of the beam 2 is set to match, so when the driving component is started, the outer web 7 and the inner web 8 move close to each other until the inner side of the outer web 7 is tightly fitted against the outer side of the front track beam 1 and the rear track beam 2, and the outer side of the inner web 8 is tightly fitted against the inner side of the front track beam 1 and the rear track beam 2, and the front track beam 1 and the rear track beam 2 are clamped at the connecting seams by the outer web 7 and the inner web 8, thereby achieving the preliminary connection of the track; then, when the outer web 7 and the inner web 8 move close to each other and completely fit in the connecting seams, the clamping component further clamps the outer web 7 and the inner web 8 to the arc cross beam 20 from the bottom, so that the entire connection structure forms a tighter and more stable whole, and the bearing capacity of the track connection structure is significantly increased. The outer web 7 and the inner web 8 are firmly fixed to the curved cross beam 20, so that the track connection can be strengthened and the train can be more comfortable. It can withstand various external forces generated by the running of the train, maintain the stability of the track connection, reduce the shaking and vibration caused by loose connection, provide a stable operating environment for the train, and improve the riding comfort of passengers; through the reinforcement component, during the normal use of the track, when the track is subjected to external force, the external force will be evenly transferred to the auxiliary plate 21 and the support beam 22, reducing the direct impact of the external force on the outer web 7, and maintaining the stability of the outer web 7. The stable connection of the outer web 7 can effectively reduce the vibration of the track during the operation of the train. The train will generate impact energy on the track when it is running. The reinforcement component reduces the vibration amplitude of the track by dispersing and bearing this impact energy, making the train run more smoothly and further improving the riding comfort of passengers.

[0032] like Figures 3 and 4 As shown, in one embodiment of the present invention, the driving assembly includes a positioning slide 9, the inner wall of the positioning slide 9 is rotatably connected to a bidirectional threaded rod 11, the bidirectional threaded rod 11 is divided into two sections and the outer walls are threadedly connected to an internal threaded slider 10, the internal threaded slider 10 is slidably connected to the inner wall of the positioning slide 9, one end of the bidirectional threaded rod 11 is fixedly connected to a knob 12, and one side of the two internal threaded sliders 10 is respectively fixedly connected to the inner side of the outer web 7 and the inner side of the inner web 8.

[0033] During operation: the positioning slide 9 is firmly installed in a suitable position above the front track beam 1 and the rear track beam 2, providing stable support and guidance for the entire driving process, and turning the knob 12. The rotation of the knob 12 will drive the bidirectional threaded rod 11 to rotate in the inner wall of the positioning slide 9. The two sections of the thread of the bidirectional threaded rod 11 rotate in opposite directions, and the two internal threaded sliders 10 will move in opposite directions. One of the internal threaded sliders 10 drives the outer web 7 to move toward the outside of the connection between the front track beam 1 and the rear track beam 2, and the other internal threaded slider 10 drives the inner web 8 to move toward the inside of the connection between the front track beam 1 and the rear track beam 2. The outer web 7 and the inner web 8 complete the clamping of the connecting seam between the front track beam 1 and the rear track beam 2, and realize the initial connection of the track.

[0034] like Figures 3 and 4 As shown, in one embodiment of the present invention, both sides of the positioning slide 9 are fixedly connected with limiting blocks 13, and the tops of the front track beam 1 and the rear track beam 2 are fixedly connected with positioning grooves 14, and the limiting blocks 13 can be embedded in the inner wall of the positioning groove 14.

[0035] During operation: When the positioning slide 9 is placed above the front track beam 1 and the rear track beam 2, the two limit blocks 13 can be embedded in the two positioning grooves 14 so that the positioning slide 9 can be located at the center of the connecting seam between the front track beam 1 and the rear track beam 2, providing a stable reference for the outer web 7 and the inner web 8, so that they can symmetrically and evenly clamp the track connection when moving, ensuring a firm and reliable connection.

[0036] like Figures 4 and 5 As shown, in one embodiment of the present invention, the positioning assembly includes a plurality of trapezoidal blocks 15, which are symmetrically fixedly connected to the bottom positions of the sides of the outer web 7 and the inner web 8, and the bottom of the arc-shaped crossbeam 20 is symmetrically slidably connected to the sliding plate 17, and one side of the sliding plate 17 is fixedly connected to the connecting block 16, and one end of the connecting block 16 is a slope.

[0037] like Figure 5 As shown, in one embodiment of the present invention, the bottom of the arc-shaped beam 20 is symmetrically fixedly connected to a fixed plate 18 , and a plurality of first springs 19 are fixedly connected between one side of the sliding plate 17 and one side of the fixed plate 18 .

[0038] During operation: When the track connection operation is performed, the outer web 7 and the inner web 8 move toward the arc-shaped crossbeam 20 under the action of the driving assembly, and the trapezoidal block 15 also moves accordingly. As the outer web 7 and the inner web 8 continue to approach the arc-shaped crossbeam 20, the trapezoidal block 15 gradually approaches the connecting block 16. When the inclined surface of the trapezoidal block 15 contacts the inclined surface of one end of the connecting block 16, the trapezoidal block 15 continues to move, which will generate an oblique squeezing force on the inclined surface of the connecting block 16. Under the action of this squeezing force, the connecting block 16 will drive the sliding plate 17 to slide along the bottom of the arc-shaped crossbeam 20 toward the fixed plate 18. At the same time, the first spring 19 between the sliding plate 17 and the fixed plate 18 will be compressed. When the trapezoidal block 15 moves to a certain position, After passing the highest point of the inclined surface of the connecting block 16, the connecting block 16 and the sliding plate 17 rebound rapidly under the action of the elastic force of the first spring 19. At this time, the connecting block 16 will be stuck in a specific position of the trapezoidal block 15, usually at the right-angled side of the trapezoidal block 15, to form a fixed position. This fixed position prevents the outer web 7 and the inner web 8 from moving away from the arc-shaped crossbeam 20, thereby firmly fixing the outer web 7 and the inner web 8 at the corresponding positions of the arc-shaped crossbeam 20, thereby achieving stable reinforcement of the track connection and enhancing the overall structural strength and stability of the track.

[0039] like Figures 6 to 8 As shown, in one embodiment of the present invention, the reinforcement component includes two auxiliary plates 21, both of which are attached to the outer side of the outer web 7, and a support beam 22 is fixedly connected between the inner walls of the auxiliary plates 21, forming a triangle between the auxiliary plates 21 and the support beam 22, and binding components are provided on both sides of the auxiliary plates 21 to connect the auxiliary plates 21 to the outer walls of the front track beam 1 and the rear track beam 2.

[0040] During operation: the auxiliary plates 21 are connected to the outer web 7 in a vertical relationship. The two auxiliary plates 21 of the reinforcement assembly are fixedly connected to the outer side of the outer web 7. During the installation phase of the overall device, they will be moved to the connection position of the front track beam 1 and the rear track beam 2 together with the outer web 7. After the outer web 7 is initially positioned, the auxiliary plates 21 are tightly connected to the outer wall of the track beam with the help of the binding components on both sides; during normal use of the track, the auxiliary plates 21 rely on the stable triangular structure formed with the support beam 22 to effectively disperse and withstand the external force acting on the track, and maintain a relatively static and stable state.

[0041] like Figures 6 to 8As shown, in one embodiment of the present invention, the binding assembly includes a plurality of side connecting plates 23, and the side connecting plates 23 are respectively fixedly connected to one side of the auxiliary plate 21, and one end of the side connecting plate 23 is fixedly connected to a hinge 24, and the inner wall of the hinge 24 is hinged with a hinge rod 25, and a second spring 30 is fixedly connected between the hinge 24 and one side of the hinge rod 25, and the outer sides of the front track beam 1 and the rear track beam 2 are fixedly connected with a connecting frame 27, and one end of the connecting frame 27 is fixedly connected to a fixed block 26.

[0042] During operation: When performing the track reinforcement installation operation, the operator holds the auxiliary plate 21 with both hands, applies appropriate and uniform force, and pushes it smoothly toward the track beam. The auxiliary plate 21 gradually approaches the outer side of the outer web 7 until it fits tightly. This fitting process ensures that there is no gap between the auxiliary plate 21 and the outer web 7, providing a stable reference for the installation of subsequent binding components. As the auxiliary plate 21 moves, the multiple side plates 23 fixed on one side of it move synchronously. When the auxiliary plate 21 continues to approach the track beam, one end of the hinged rod 25 will contact the fixed block 26 on the outer connecting frame 27 of the track beam. At this time, the operator continues to push the auxiliary plate 21, and the fixed block 26 generates a force on the hinged rod 25, so that The hinged rod 25 rotates around the hinge point of the hinge 24. During the rotation of the hinged rod 25, the second spring 30 fixedly connected between the hinge 24 and one side of the hinged rod 25 is subjected to pressure and is gradually compressed. The hinged rod 25 moves along one side of the fixed block 26. When it is no longer in contact with the fixed block 26, under the reaction of the second spring 30, the hinged rod 25 quickly returns to its original position, and at this time one end of it is precisely engaged with one end of the fixed block 26. At this point, the binding assembly is installed, and the auxiliary plate 21 is firmly connected to the track beam.

[0043] like Figures 7 and 8 As shown, in one embodiment of the present invention, a pair of connecting seats 28 are fixedly connected to one side of the connecting frame 27 , and a positioning pin 29 is fixedly connected to the inner wall of the connecting seat 28 .

[0044] During operation: When the hinged rod 25 returns to its original position and one end of it is engaged with one end of the fixed block 26, the other side of the hinged rod 25 is restricted by the positioning pin 29. During the operation of the track, if the auxiliary plate 21 and the outer web 7 are subjected to impact force, this impact force may cause the hinged rod 25 to have a tendency to rotate, but due to the restriction of the positioning pin 29, the hinged rod 25 cannot rotate at will, thereby ensuring the stability of the binding assembly, ensuring that the auxiliary plate 21 is always firmly connected to the track beam, and providing reliable protection for the safe operation of the track.

[0045] like Figure 2As shown, in one embodiment of the present invention, the cross-section of the front track beam 1 is symmetrically fixedly connected with an arc-shaped embedding plate 3, and the cross-section of the rear track beam 2 is symmetrically provided with an embedding groove 4. The arc-shaped embedding plate 3 and the embedding groove 4 are slidingly connected and adapted to each other. One side of the arc-shaped cross beam 20 connected to the bottom of the front track beam 1 is symmetrically fixedly connected with a protrusion 5, and one side of the arc-shaped cross beam 20 connected to the bottom of the rear track beam 2 is symmetrically provided with a groove 6, and the protrusion 5 and the groove 6 are clamped together.

[0046] During operation: Before the track beams are assembled, the front track beam 1 and the rear track beam 2 are in a relatively separated state. When the connection operation begins, the operator will slowly move the front track beam 1 or the rear track beam 2 so that the two are gradually closer. The arc-shaped splicing plate 3 on the front track beam 1 will gradually approach the splicing groove 4 on the rear track beam 2, guiding the front track beam 1 and the rear track beam 2 to dock in the correct direction, ensuring that the positions of the two in the horizontal and vertical directions are accurately aligned.

[0047] like Figure 2 As shown, in one embodiment of the present invention, a protrusion 5 is symmetrically fixedly connected to one side of the arc-shaped cross beam 20 connected to the bottom of the front track beam 1, and a groove 6 is symmetrically opened on one side of the arc-shaped cross beam 20 connected to the bottom of the rear track beam 2, and the protrusion 5 and the groove 6 are clamped together.

[0048] During operation: the protrusion 5 on the arc-shaped cross beam 20 at the bottom of the front track beam 1 gradually approaches the groove 6 on the arc-shaped cross beam 20 at the bottom of the rear track beam 2, and the protrusion 5 will be embedded in the groove 6, realizing the fixed connection between the front track beam 1 and the rear track beam 2 in the vertical direction. The front track beam 1 and the rear track beam 2 are formed into a stable and firm overall structure through the sliding connection between the arc-shaped embedding plate 3 and the embedding groove 4 and the clamping connection between the protrusion 5 and the groove 6, completing the connection and installation process and facilitating the subsequent reinforcement connection process.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
