Description

Technical Field

[0001] This invention relates to the field of bridge construction equipment technology, and in particular to a railway beam transport device. Background Technology

[0002] In areas of my country where railway bridges were built relatively early, especially in mountainous regions, bridges are severely aging. With the increase in railway speed and expanded transport capacity, the strength and rigidity of these old bridges can no longer meet the requirements of modern railways, necessitating replacement with newer, stronger, and more durable bridges. During the replacement or construction of existing railway bridges, beam transport equipment is indispensable. Existing beam transport equipment is generally adapted to road conditions outside of existing railway lines and is ill-suited for transporting beams along the large curve radii on existing railway lines. Therefore, existing beam transport equipment is significantly limited in its application to existing railway lines, creating a substantial demand for dedicated railway beam transport equipment.

[0003] Existing railway beam transport equipment generally includes a car body and running gear. The replacement of simply supported beams is carried out through the cooperation of the railway beam transport equipment and the railway beam replacement device. Existing railway beam transport equipment is generally large. During the replacement of simply supported beams, the old simply supported beam needs to be disassembled and transported away, and then the new simply supported beam needs to be installed in the original installation position of the disassembled beam. When loading the old, disassembled simply supported beam onto the railway beam transport equipment or moving the new simply supported beam to the rear of the car, the weight of the beam will cause the rear of the car to sink, causing one end of the car front to tilt upwards. This makes the entire car body unstable and prone to tipping over, creating a safety hazard.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] This invention provides a railway beam transport device.

[0006] The present invention adopts the following technical solution:

[0052] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] See Figures 1 to 15As shown, the present invention provides a railway beam transport device, comprising: a car body and a small trolley 2. The car body includes a frame 1 and a track running device a connected to the frame 1. The frame 1 is used to carry the simply supported beam to be transported. A corresponding number of track running devices a can be set according to the length of the frame 1, and each running device is equipped with at least one shock-absorbing device a1. A support device 6 is provided on the frame 1, which is used to support a railway beam transfer device 3. The small trolley 2 is detachably connected to the car body. The small trolley is used to install the railway beam transfer device 3, and the small trolley 2 has the track running device a. The small trolley 2 has a structure basically the same as the track running device a, and its function is to carry and transport the railway beam transfer device, with a load-bearing capacity superior to that of the track running device a. The track running device a is equipped with hook and buffer devices b at both ends, and the small trolley 2 is equipped with one hook and buffer device b at one end near the vehicle body. When the beam replacement operation is performed, the frame 1 and the small trolley 2 are connected by the hook and buffer device b. When the operation is not performed, the hook and buffer device b and the support device 6 are disconnected, and the frame 1 and the small trolley 2 can be separated for easy transfer.

[0057] like Figure 1 As shown, the railway beam transport equipment of this application has a support device 6 on the frame 1. The support device 6 allows the frame 1 to be supported on the railway beam replacement device 3. During the operation of replacing the simply supported beam, when the simply supported beam is moved to the rear of the car, the support device 6 allows the rear of the car to be supported on the railway beam replacement device 3. This ensures that when the rear end of the car is subjected to the gravity of the simply supported beam, the front end of the car will not tilt upwards, making the entire car body stable and less prone to tipping over, thus reducing safety hazards.

[0058] like Figure 2 As shown, the support device 6 includes a main body 61 and a movable part 62. The movable part 62 is connected to the main body 61 and can move up and down along the main body 61 to support the railway transshipment rack device 3. The railway transshipment rack device 3 has a bottom beam. When the heights of the car frame 1 and the railway transshipment rack device 3 are different, the support device 6 can be adjusted to raise or lower it, so that the support device 6 can be stably supported on the upper surface of the bottom beam. In this way, the support device 6 can adapt to different scenario requirements.

[0059] The main body 61 is provided with a threaded hole (not shown), such as Figure 2As shown, the movable part 62 includes a lead screw 621 and a support plate 622. The lead screw 621 is threaded into the threaded hole, and the support plate 622 is connected to the bottom end of the lead screw 621. The support plate 622 is used to support the railway transfer frame device 3. The support plate 622 can be annular, and its outer diameter is larger than that of the lead screw. The use of the support plate 622 increases the contact area between the lower surface of the main body 61 and the upper surface of the bottom beam of the railway transfer frame device 3, thus improving the stability of the vehicle body. In practical applications, multiple support plates 622 can be set as needed to increase the stability of the connection.

[0060] The main body 61 is provided with at least two threaded holes, which are spaced apart sequentially along the width direction of the vehicle body. Lead screws 621 of at least two movable parts 62 are respectively connected to corresponding threaded holes. The lead screws 621 pass through the threaded holes and are threadedly connected to them. Multiple threaded holes are provided, allowing a corresponding number of lead screws 621 to pass through their respective threaded holes. The cooperation of multiple threaded holes and multiple lead screws 621 makes the overall structure more stable.

[0061] The lead screw 621 has a rotating engagement part (not shown) at the end opposite to the support plate 622. The rotating engagement part can be a groove with a Phillips head or a slotted head, such as on a screw cap. A special tool can be inserted into the rotating engagement part, and rotating the tool will cause the lead screw 621 to rotate. During rotation, the lead screw 621 drives the main body 61 to move up and down. The lead screw 621 can be completely concealed inside the railway transshipment device 3.

[0062] The frame 1 includes an end beam 122 and two side beams, which are spaced apart. The end beam 122 is located at the end of the side beams and connects the two side beams. The main body 61 is connected to the end beam 122. The lead screw 621 extends out of the end beam 122 for easy connection via a lead screw.

[0063] like Figure 2 As shown, the main body 61 includes a wedge-shaped block 611 and a flat thick plate 612. The tip of the wedge-shaped block 611 is connected to the end beam 122, and the flat thick plate 612 is connected to the other end of the wedge-shaped block 611. A threaded hole is provided in the flat thick plate 612, and the threaded hole penetrates the flat thick plate 612 along its thickness direction. The main body 61 can be connected to the end beam 122 of the vehicle body by welding or fasteners. The flat thick plate 612 has a certain thickness, which facilitates the setting of the threaded hole. The threaded hole is relatively long, which facilitates rotation within it and facilitates connection using a lead screw.

[0064] In one possible implementation, such as Figure 6As shown, the side beam includes a detachably connected first side beam 111 and a second side beam 121, wherein two spaced-apart first side beams 111 form the main frame 11. An end beam 122 connects to two second side beams 121 respectively. The end beam 122 and the spaced-apart second side beams 121 form the towing frame 12, which is detachably connected to the main frame 11. Figure 2 As shown, the support device 6 is disposed on the end beam 122. Specifically, the support device 6 is disposed on the end beam 122 at the end of one of the traction frames 12. Multiple crossbeams 112 are sequentially spaced between the two first side beams 111, and the multiple crossbeams 112 are arranged in parallel. The crossbeams 112 and side beams ensure the structural strength of the main frame 11, enabling the frame 1 to normally bear the simply supported beam. Before transporting the railway beam transport equipment to the designated location, the main frame 11 and the two traction frames 12 can be disassembled and transported separately. The disassembled main frame 11 and traction frames 12 are shorter, facilitating road transport. After transport to the designated location, the main frame 11 and the two traction frames 12 are then connected and fixed. The frame 1 of the railway beam transport equipment of this application is a detachable structure, solving the problem of traditional railway beam transport equipment having excessively long bodies and difficult transportation.

[0065] like Figure 5 As shown, the first side beam 111 includes an upper side beam 1111 and a lower reinforcing beam 1112. A reinforcing plate is provided in the middle of the upper side beam 1111. The reinforcing plate extends outward along the width direction of the frame 1. In the direction from the middle of the reinforcing plate to both sides, the reinforcing plate gradually moves closer to the upper side beam 1111. The lower reinforcing beam 1112 is connected to the upper side beam 1111. The reinforcing plate makes the upper side beam 1111 form a fish-belly-shaped structure that is larger in the middle and smaller on both sides, resulting in higher structural strength, less deformation under heavy loads, and better durability.

[0066] In one possible implementation, such as Figure 13 , Figure 14 and Figure 15As shown, the frame 1 includes a connecting device 4. The first side beam 111 is provided with a first insertion structure 1113, and the second side beam 121 is provided with a second insertion structure 1211. The first insertion structure 1113 has multiple first insertion plates 1113a, and the second insertion structure 1211 has multiple second insertion plates 1211a. When the first side beam 111 and the second side beam 121 are connected, the second insertion structure 1211 is inserted into the first insertion structure 1113, with each second insertion plate 1211a and each first insertion plate 1113a interleaved. The connecting device 4 connects the first insertion plates 1113a and the second insertion plates 1211a to connect and fix the first insertion structure 1113 and the second insertion structure 1211. The first insertion structure 1113 and the second insertion structure 1211 can be fixed to both ends of the first side beam 111 and the corresponding second side beam 121 by welding. This connection structure has high strength, is easy to assemble and disassemble, and can significantly improve work efficiency.

[0067] like Figure 14 As shown, the number of second insert plates 1211a in the second insertion structure 1211 is twice the number of first insert plates 1113a in the first insertion structure 1113. Two second insert plates 1211a spaced apart form an insert plate group, and a joint is formed between the two second insert plates 1211a in each insert plate group. In the coupled state, each first insert plate 1113a is inserted into the joint b of the corresponding insert plate group. The number of first insertion structures 1113 can be set according to actual needs. The more first insert plates 1113a provided, the higher the connection strength between the first insertion structure 1113 and the second insertion structure 1211. Correspondingly, the same number of insert plate groups are provided to accommodate the number of first insert plates 1113a.

[0068] like Figure 14 and Figure 15 As shown, both the first insert plate 1113a and the second insert plate 1211a are provided with multiple through holes c. Each through hole c on the first insert plate 1113a and the second insert plate 1211a is opposite to the first insert plate 1113a and the second insert plate 1211a. Multiple connecting devices 4 pass through the corresponding through holes c on the first insert plate 1113a and the second insert plate 1211a respectively to connect the first insert plate 1113a and the second insert plate 1211a.

[0069] like Figure 14 and Figure 15As shown, the connecting device 4 includes a connecting pin 41 and an end limiting member 42. The connecting pin 41 includes a pin shaft and a cap body (not shown). The cap body is connected to one end of the pin shaft. The pin shaft passes through the through hole c on the first insert plate 1113a and the second insert plate 1211a. The end limiting member 42 is detachably connected to the end of the pin shaft opposite to the cap body.

[0070] like Figure 15 As shown, an annular groove 411 is provided at the end of the pin opposite to the cap body, and the end limiting member 42 is engaged with the annular groove 411. In the engaged state, the end limiting member 42 and the cap body limit and fix the first insertion structure 1113 and the second insertion structure 1211, making the pin difficult to disengage and ensuring a tight connection.

[0071] like Figure 15 As shown, the end limiting member 42 includes two semi-rings 421, which are respectively engaged with the annular groove 411. The semi-rings 421 are connected to the first insert plate 1113a or the second insert plate 1211a. The inner diameter of the two semi-rings 421 is smaller than the outer diameter of the pin and larger than the inner diameter of the annular groove 411. The two semi-rings 421 can be closed to form a ring and engaged with the annular groove 411, allowing them to be easily engaged within the annular groove 411.

[0072] like Figure 15 As shown, a connecting hole 4211 is provided on the semi-ring 421. A fastener (not shown) passes through the connecting hole 4211 and is connected to the first insert plate 1113a or the second insert plate 1211a. Threaded holes can be provided at corresponding positions on the first insert plate 1113a or the second insert plate 1211a at both ends. The fastener can be a screw, with the screw shank passing through the connecting hole 4211 and connecting to the threaded hole at the corresponding position on the first insert plate 1113a or the second insert plate 1211a for connection and fixation. The screw head is limited to the side of the semi-ring 421 facing away from the first insert plate 1113a or the second insert plate 1211a.

[0073] The semi-ring 421 is provided with a plurality of connecting holes 4211, which are arranged sequentially at intervals along the length of the semi-ring 421. A plurality of fasteners pass through the corresponding connecting holes 4211 and are connected to the first insert plate 1113a or the second insert plate 1211a. The pin is fixed in place by the plurality of fasteners along the length of the semi-ring 421, so that the pin is tightly fixed and prevented from moving during the use of the railway beam transport equipment, which would cause the connection structure to become unstable and cause safety hazards.

[0074] like Figure 15As shown, the first insertion structure 1113 includes a first end plate 1113b and two first side plates 1113c perpendicularly disposed on both sides of the first end plate 1113b. Each first insertion plate 1113a is located between the two first side plates 1113c, and the first insertion plate 1113a is perpendicularly connected to the first side plates 1113c and the first end plate 1113b, with the first insertion plate 1113a extending out of the first side plates 1113c. The fact that the first insertion plate 1113a partially extends out of the two first side plates 1113c facilitates alignment when the first insertion structure 1113 and the second insertion structure 1211 are connected. The three end faces of the first insertion plate 1113a are respectively connected between the first end plate 1113b and the two first side plates 1113c, resulting in a connection structure with high strength and durability. The first end plate 1113b, the two first side plates 1113c and the first insert plate 1113a in the first plug-in structure 1113 can be welded together or integrally formed. The integrally formed structure has higher strength and better durability than the welded connection structure.

[0075] like Figure 14 As shown, the second insertion structure 1211 includes a second end plate 1211b and two second side plates 1211c perpendicularly disposed on both sides of the second end plate 1211b. Each second insertion plate 1211a is located between the two second side plates 1211c, and the second insertion plate 1211a is perpendicularly connected to the second side plates 1211c and the second end plate 1211b, respectively, with the second insertion plate 1211a extending out of the second side plates 1211c. The fact that the second insertion plate 1211a partially extends out of the two second side plates 1211c facilitates alignment when the first insertion structure 1113 and the second insertion structure 1211 are connected. The three end faces of the second insertion plate 1211a are respectively connected between the second end plate 1211b and the two second side plates 1211c, resulting in a connection structure with high strength and durability. The connection between the second end plate 1211b, the two second side plates 1211c and the second plug plate 1211a in the second plug structure 1211 can be a welded connection or an integral molding. The integral molding structure has higher strength and better durability than the welded connection structure.

[0076] In the combined state, the opposing first side plate 1113c and second side plate 1211c are located in the same plane. Each second insert plate 1211a and each first insert plate 1113a are staggered and inserted together. The end faces of the first side plate 1113c and the second side plate 1211c are connected and located in the same plane, forming a configuration as shown below. Figure 13 The shape shown.

[0077] In one possible implementation, such as Figure 1 As shown, two rails 13 are provided on the upper side of the frame 1, and the two rails 13 are connected and fixed to the frame 1 by welding. A rolling transport platform 8 is provided on the upper side of the rails 13. The rolling transport platform 8 can reciprocate along the extension direction of the frame 1 on the frame 1. The rolling transport platform 8 is used to transport new beams or old beams. At least one rolling transport platform 8 can be provided, or two, three or more can be provided according to actual needs. For example, there are two rolling transport platforms 8. When transporting a simply supported beam, the simply supported beam is placed on the rolling transport platform 8, and the two rolling transport platforms 8 are respectively set at both ends of the simply supported beam to support it.

[0078] The rolling transport platform 8 has two wheel sets, which are respectively located on both sides of the rolling transport platform 8 and on the two side beams of the frame 1. Each wheel set consists of multiple rollers, which are parallel to each other and have horizontally arranged axles. The multiple rollers provide horizontal support for the moving surface of the rolling transport platform 8, allowing the rolling transport platform 8 to move stably on the frame 1.

[0079] In one possible implementation, a core plate device d and a side bearing device e are provided between the small trolley 2 and the railway transfer rack device 3. The core plate device d and the side bearing device e enable relative movement between the small trolley 2 and the railway transfer rack device 3 while providing stable support. Figure 7 and Figure 8 As shown, the core plate device d has a lower core plate d1, an upper core plate d2, and a center pin d3. The lower core plate d1 and the upper core plate d2 are connected by the center pin d3. In practical applications, an anti-detachment center pin d3 can be selected for better structural stability. The side bearing device e has a lower side bearing e1, a side bearing mounting seat e2, and a side bearing adjusting pad e3. The lower side bearing e1 is disposed inside the side bearing mounting seat e2, and an adjusting pad is disposed on the lower side of the lower side bearing e1 for adjusting the height of the lower side bearing e1. The core plate device d and the side bearing device e are commonly used structures in existing railway beam transport equipment and are mature existing technologies. This application will not elaborate on their working principles.

[0080] In one possible implementation, the vehicle body includes several trolley systems, each trolley system being arranged sequentially at intervals along the length of the frame 1. Typically, there are two trolley systems, arranged one after the other. The frame 1 has sufficient length to accommodate both trolley systems simultaneously. The two trolley systems are connected via the frame 1. However, the number of trolley systems is not limited to two; it can also be three or more. When there are multiple trolley systems, they are arranged sequentially at intervals below the frame 1 along its length. Each trolley system includes a small base frame 5 and a track running device a. The frame 1, the small base frame 5, and the track running device a are arranged longitudinally. A core plate device d and a side bearing device e are arranged between adjacent pairs of the frame 1, the small base frame 5, and the track running device a.
