Description

[0002] In areas of my country where railway bridges were built relatively early, especially in mountainous regions, the bridges are severely aging.

[0038] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0039] See Figures 1 to 12As shown, this embodiment provides a three-stage balanced structure railway beam transport equipment, including: a frame 1, a middle base frame 2, a small base frame 3, a track running device 4, and a small trolley 19. The middle base frame 2 is located at the bottom of the frame 1, and a core plate device 5 and a side bearing device 6 are arranged between the middle base frame 2 and the frame 1. The small base frame 3 is located at the bottom of the middle base frame 2, and a core plate device 5 and a side bearing device 6 are arranged between the small base frame 3 and the middle base frame 2. The track running device 4 is located at the bottom of the small base frame 3, and a core plate device 5 and a side bearing device 6 are arranged between the track running device 4 and the small base frame 3. The small trolley 19 is detachably connected to the small base frame 3 located at the end of the frame 1. The small trolley 19 is used to install the railway beam transport device, and the small trolley 19 has a track running mechanism 191. The three-stage balanced structure railway beam transport equipment provided in this application consists of a track running device 4, a small base frame 3, a middle base frame 2, and a vehicle frame 1 arranged sequentially from bottom to top. The track running device 4 and the small base frame 3 form one stage, the small base frame 3 and the middle base frame 2 form another stage, and the middle base frame 2 and the vehicle frame 1 form yet another stage, for a total of three stages. This beam transport equipment enables universal beam replacement and transport construction for railway bridges, suitable for complex and extreme environments such as high clearance areas, heavy loads, areas under bridges, and tunnels. Compared to single-stage and two-stage balanced structure beam transport vehicles, the three-stage balanced structure railway beam transport equipment has more track running devices 4 below the middle base frame 2. The increased number of track running devices 4 gives this beam transport equipment the characteristics of low clearance and heavy load structure transportation, enabling it to carry and transport large-section heavy-load beams, goods, and equipment. The beam transport vehicle carries beams longer than sixteen meters, a beam replacement working device, and a power control device, achieving integrated beam replacement and transport, improving work efficiency, reducing beam replacement time and costs, and representing a significant breakthrough in beam replacement technology. Meanwhile, a railway beam-changing device can be installed on the small trolley 19. This device is crucial for transferring the old beam to the new one after the new simply supported beam has been transported to its destination. The small trolley and the small base frame at the end of the frame are detachably connected, facilitating separation of the trolley from the frame and enabling the loading and transfer of the railway beam-changing device. This provides greater flexibility and reduces engineering difficulty. Furthermore, the track running device 4 and track running mechanism 191 enable this application to be carried out on railway tracks, meeting the requirements for transporting beams with large curve radii on railway lines. The core plate device 5 includes an upper core plate and a lower core plate. The upper core plate is located on the upper component of two adjacent components, and the lower core plate is located on the lower component. The connection method between the upper and lower core plates is existing technology and will not be described further here. The side bearing device 6 includes a plurality of balls that support the component above it and reduce friction when the component moves relative to the component below it. The side bearing device 6 is also prior art. The specific structure of the side bearing device 6 other than the balls will not be described in detail in this application.

[0040] See Figure 2 As shown, the small trolley 19 has a trolley base frame 192, and the track running mechanism 191 is disposed at the bottom of the trolley base frame 192; a core plate device 5 and a side bearing device 6 are disposed between the trolley base frame 192 and the track running mechanism 191; a railway transfer frame device (not shown in the figure) is supported on the trolley base frame 192, and a core plate device 5 and a side bearing device 6 are disposed between the railway transfer frame device and the trolley base frame 192; the trolley base frame 192 and the small base frame 3 located at the end of the frame 1 are connected by a coupler buffer device 15.

[0041] In this technical solution, the track traveling mechanism 191 has rollers that can travel on the track, thus ensuring that the trolley 19 can travel on the track. The trolley base 192 of the trolley 19 is used for load-bearing, and the railway transfer device can be installed on the trolley base 192.

[0042] In one possible implementation, the three-level balanced structure railway beam transport equipment includes a tail support device 20, which is connected to the frame 1 and supported on the rail or the railway beam transport device, playing a stabilizing support role and preventing the end support of the frame from becoming unstable when the simply supported beam moves to the end side of the frame.

[0043] Specifically, the tail support device 20 has two beams 24 spaced apart; the small base frame 3 at the end of the frame 1 is connected to a traction beam 25; the end of the traction beam 25 is provided with an end plate 26, which is used to connect a coupler buffer device 15, which is connected to the small trolley 19; the end plate 26 is provided with clearance parts on both sides, which are used to avoid the beams 24.

[0044] In this embodiment, the traction beam 25 extends out of the track running device 4. Adding the traction beam 25 facilitates connection with the trolley 19. The end plate 26 of the traction beam 25 has a large side area, which also facilitates the installation of the coupler buffer device 15. After the tail support device 20 is connected to the frame 1, sections of the two beams 24 of the tail support device 20 are located at the clearance portion of the end plate 26. This allows the tail support device 20 and the traction beam 25 to nest together, facilitating their assembly, preventing interference, and thus making the connection between the tail support device 20 and the frame 1 more secure.

[0045] See Figure 8As shown, the traction beam 25 has an inverted T-shaped structure design, including a middle beam 27, end plates 26, reinforcing beams 28, front follower plate seats 29, rear follower plate seats 30, and reinforcing plates 34. The middle beam 27 has a knife-handle-shaped structure, with the knife head welded and fixed to the end plate 26; the reinforcing beams 28 are welded and fixed to both the middle beam 27 and the end plate 26; two front follower plate seats 29, two rear follower plate seats 30, and four reinforcing plates 34 are symmetrically arranged on both sides of the middle beam 27. The front follower plate seats 29 and rear follower plate seats 30 are fixed using standard parts, and the reinforcing plates 34 are welded and fixed.

[0046] See Figure 4 As shown, the intermediate frame 2 includes a first intermediate beam 21, a first end bolster beam 22, and a first middle bolster beam 23; the first end bolster beam 22 is disposed on both sides of the end of the first intermediate beam 21; the first middle bolster beam 23 is disposed on both sides of the middle of the first intermediate beam 21; a side bearing device 6 is disposed between the first end bolster beam 22 and the small frame 3, and a core plate device 5 is disposed between the end of the first intermediate beam 21 and the small frame 3; a core plate device 5 is disposed between the portion of the first intermediate beam 21 located between the two first middle bolster beams 23 and the frame 1, and a side bearing device 6 is disposed between the portion of the first intermediate beam 21 on which the first middle bolster beam 23 is mounted and the frame 1.

[0047] Specifically, the thickness of the first intermediate beam 21 gradually decreases from the middle to both ends. The first intermediate beam 21 is a concave box girder structure. Since the middle part of the first intermediate beam 21 is the main load-bearing area, the gradual decrease in thickness from the middle to both ends ensures that the middle part has sufficient load-bearing capacity.

[0048] See Figure 5 As shown, the first intermediate beam 21 has a first web 211, a first lower cover plate 212, and a first upper cover plate 213; the first web 211 is disposed between the first upper cover plate 213 and the first lower cover plate 212, and the first web 211 is connected to the first upper cover plate 213 and the first lower cover plate 212 respectively; the first upper cover plate 213 has an integrally formed first extension plate extending vertically to both sides in the middle; the first middle bolster beam 23 is fixed to the lower side of the first extension plate.

[0049] In this technical solution, the first intermediate beam 21 is welded together from a first web 211, a first lower cover plate 212, and a first upper cover plate 213, meaning the first intermediate beam 21 is a hollow structure, which ensures structural strength while reducing its own weight. In the prior art, the first extension plate is welded to the main body of the first upper cover plate 213, while this application uses integral molding, which makes the structural strength of the first intermediate beam 21 higher. The first intermediate beam 21 also includes a first partition plate 214, which is a transverse through-stiffener connected between the left and right first webs 211. The arrangement of the first partition plate 214 further enhances the structural strength of the first intermediate beam 21.

[0050] Specifically, the first lower cover plate 212 includes a first intermediate lower cover plate and a first end lower cover plate; the first end lower cover plate is disposed on both sides of the first intermediate lower cover plate; in the direction from the first intermediate lower cover plate to both ends of the first intermediate beam 21, the first end lower cover plate gradually approaches the first upper cover plate 213, and the first end lower cover plate is arc-shaped.

[0051] In this embodiment, the first intermediate lower cover plate is a square plate, and its area is the main load-bearing surface. The first end lower cover plates on both sides of the first intermediate lower cover plate are arc-shaped mainly to avoid the small base frame 3 located below them.

[0052] See Figure 6 As shown, the small base frame 3 includes a second intermediate beam 31, a second end pillow beam 32, and a second middle pillow beam 33; the second end pillow beam 32 is disposed on both sides of the end of the second intermediate beam 31; the second middle pillow beam 33 is disposed on both sides of the middle of the second intermediate beam 31; a side bearing device 6 is disposed between the second end pillow beam 32 and the small base frame 3, and a core plate device 5 is disposed between the end of the second intermediate beam 31 and the small base frame 3; a core plate device 5 is disposed between the portion of the second intermediate beam 31 located between the two second middle pillow beams 33 and the middle base frame 2, and a side bearing device 6 is disposed between the portion of the second intermediate beam 31 on which the second middle pillow beam 33 is installed and the middle base frame 2.

[0053] In this technical solution, the small base frame 3 is formed by welding the second intermediate beam 31, the second end pillow beam 32, and the second middle pillow beam 33.

[0054] See Figure 7As shown, the second intermediate beam 31 has a second web 311, a second lower cover plate 312, and a second upper cover plate 313; the second web 311 is disposed between the second upper cover plate 313 and the second lower cover plate 312, and the second web 311 is connected to the second upper cover plate 313 and the second lower cover plate 312 respectively; the second upper cover plate 313 has a second extension plate integrally formed in the middle, extending vertically to both sides; the second middle bolster beam 33 is fixed to the lower side of the second extension plate.

[0055] In this embodiment, the second intermediate beam 31 is formed by welding the second web plate 311, the second lower cover plate 312, and the second upper cover plate 313. That is, the second intermediate beam 31 is a hollow structure, which ensures structural strength while reducing its weight. The integral molding of the second extension plate and the second upper cover plate 313 further enhances the structural strength of the second intermediate beam 31. The second intermediate beam 31 also includes a second partition plate, which is a transverse through-stiffener connected between the left and right second web plates 311. The second partition plate further strengthens the structural strength of the second intermediate beam 31.

[0056] See Figure 3 and Figure 12 As shown, each of the small base frames 3 is provided with two track traveling devices 4 at its bottom; the track traveling device 4 includes at least three rotating shafts 7, and each rotating shaft 7 is provided with track mating wheels 8 at both ends.

[0057] In this technical solution, there are two smaller base frames 3 under the central base frame 2. Since each smaller base frame 3 has two track running devices 4, and each track running device 4 has at least six track wheels 8, there are at least twenty-four track wheels 8 under the central base frame 2. In contrast, the primary and secondary balanced structure beam transport vehicles do not have a central base frame 2, but at most one smaller base frame 3, with only two running devices under each smaller base frame 3. This results in a maximum of sixteen transport wheels for the primary and secondary balanced structure beam transport vehicles. In comparison, the tertiary balanced structure railway beam transport equipment has more track wheels 8, thus its load-bearing capacity is greater. A braking device 16 is also installed on the track running device 4. The structure of the braking device 16 is widely disclosed in existing technology, and will not be described in detail here.

[0058] In one possible implementation, the three-level balanced structure railway beam transport equipment includes a transport platform 9; a guide rail 10 is provided on the frame 1, the guide rail 10 extends along the length direction of the frame 1; the transport platform 9 is slidably connected to the guide rail 10, and the transport platform 9 can move along the guide rail 10.

[0059] In this embodiment, the frame 1 is provided with two compartmentalized guide rails 10, which are fixedly connected to the frame 1 by welding. There are also two transport platforms 9. The transport platforms 9 are used to place the simply supported beams to be transported. The transport platforms 9 are slidably connected to the guide rails 10 so that the transport platforms 9 can slide along the frame 1 with the simply supported beams, so that the simply supported beams can be transferred to the beam replacement equipment for subsequent beam replacement work.

[0060] In one possible implementation, the three-stage balanced structure railway beam transport equipment includes a power control room 14, which is located at one end of the frame 1. The power control room 14 is fixed to the frame 1 by welding.

[0061] See Figure 10 As shown, the frame 1 includes a crossbeam 11, a bolster beam 12, and two side beams 13 spaced apart; each of the crossbeams 11 and the bolster beam 12 is disposed between the two side beams 13, and the two ends of the crossbeam 11 are respectively connected to the two side beams 13, and the two ends of the bolster beam 12 are respectively connected to the two side beams 13; a core plate device 5 is disposed between the bolster beam 12 and the middle frame 2.

[0062] In this technical solution, the crossbeam 11, the bolster beam 12, and the side beam 13 can be fixed together by welding to form the frame 1. The frame 1, composed of the crossbeam 11, bolster beam 12, and side beam 13, ensures a simple structure while also providing good load-bearing capacity. The crossbeams 11 located at both ends of the side beam 13 can also serve as end beams 17. The bolster beam 12 and the middle underframe 2 are connected by a core plate device 5, which includes an upper core plate and a lower core plate. The upper core plate is mounted on the bolster beam 12, and the lower core plate is mounted on the middle underframe 2. The connection between the upper and lower core plates achieves the connection between the frame 1 and the middle underframe 2. The connection method between the upper and lower core plates is prior art and will not be described in detail here.

[0063] See Figure 11 As shown, the lower edge of the side beam 13 is provided with several clearance notches 18, which are used to avoid the second end bolster beam 32 of the small base frame 3. Since the lower edge of the side beam 13 extends downwards for a long time and is already lower than the second end bolster beam 32 of the small base frame 3, if the clearance notches 18 are not provided, the side beam 13 and the second end bolster beam 32 of the small base frame 3 will overlap during assembly, resulting in a high beam transport vehicle of this application. When the clearance notches 18 are provided, and the second end bolster beam 32 of the small base frame 3 is located within the clearance notches 18, the height of the beam transport equipment of this application will be reduced, the center of gravity will be lowered, and the beam transport equipment will be more stable when moving.

[0064] See some possible implementations. Figure 1 and Figure 11As shown, the side beam 13 includes an upper side beam 131 and a lower side beam 132. A guide rail 10 for the movement of the transport platform 9 is provided on the upper side beam 131, and the lower side beam 132 is fixed to the upper side beam 131. The guide rail 10 is welded to the upper surface of the upper side beam 131 and is used to guide and support the transported goods. The upper side beam 131 can be a box girder structure with a constant cross-sectional area, while the lower side beam 132 can be a box girder structure with a varying cross-sectional area. That is, both the upper side beam 131 and the lower side beam 132 are hollow structures. This design ensures load-bearing capacity while reducing the weight of the frame 1.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0066] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
