Description

Technical Field

[0001] This utility model relates to the field of bridge erection technology, and specifically to a bridge. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. It can also be extended to refer to a structure built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. The construction of traditional bridges requires geological surveys and design, earthwork, foundation engineering, pier and abutment engineering, and bridge deck engineering. The erection of traditional bridges involves multiple processes and a long construction period, especially in complex geological, riverine, or marine environments. Furthermore, completed bridges are generally permanent and difficult to reuse. Especially in certain special circumstances, such as disaster relief, temporary bridge construction, and temporary near-shore passage construction, the long construction period and lack of reusability of traditional bridges make them unsuitable for these situations.

[0003] Based on the above, there is an urgent need to provide a bridge to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a bridge, and the specific technical solution is as follows:

[0005] A bridge includes a foundation platform, a bridge assembly, and a guide beam assembly. The bridge assembly is retractably mounted on the foundation platform, and the guide beam assembly is nested between the foundation platform and the bridge assembly. The guide beam assembly slides with both the foundation platform and the bridge assembly.

[0006] The basic platform is also equipped with a bridge propulsion locking device and a guide beam propulsion locking device. The bridge propulsion locking device is connected to the bridge assembly, and the guide beam propulsion locking device is connected to the guide beam assembly.

[0007] Furthermore, the guide beam assembly includes a guide beam and a guide beam guiding and limiting device. The guide beam is slidably connected to the base platform through the guide beam guiding and limiting device. The guide beam pushing and locking device is connected to the guide beam and is used to drive the guide beam to slide relative to the base platform.

[0008] Furthermore, the guide beam advancing and locking device includes a base and a drive device. The base is fixed to the foundation platform; the drive device is provided on the base and is connected to the guide beam.

[0009] Furthermore, the drive device includes a gear reducer, the output end of which is connected to a gear, which meshes with a rack on the guide beam.

[0010] Furthermore, the bridge assembly includes a bridge body and connecting structures. The connecting structures are located on both sides of the bridge body, and the two connecting structures and the bridge body cooperate to form a cavity. The guide beam is located in the cavity and slides with the bridge body.

[0011] Furthermore, a guide structure is provided between the bridge body and the guide beam. The guide structure includes a slider on the bridge body and guide wheels at both ends of the slider. The slider engages with the top surface of the guide beam, and the guide wheels engage with the side surface of the guide beam.

[0012] Furthermore, bridge guide components are symmetrically arranged at the ends of the bridge body along the extension and contraction direction of the bridge body, and the bridge guide components slide in conjunction with the foundation platform.

[0013] Furthermore, the bridge propulsion locking device includes a second base, a second drive device, and a limiting device. The second base is fixed on the foundation platform, the second drive device is disposed on the second base, and the second drive device is connected to the connecting structure. The limiting device is disposed on the second base and cooperates with the connecting structure to limit the extension and retraction of the bridge component.

[0014] Furthermore, the second driving device includes a gear reducer, the output end of which is connected to a gear, which meshes with a rack on the connecting structure.

[0015] Furthermore, the guide beam assembly also includes a support leg, which is telescopically disposed at the end of the guide beam.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] (1) This utility model provides a bridge, including a foundation platform, a bridge assembly, and a guide beam assembly. The bridge assembly is telescopically mounted on the foundation platform, and the guide beam assembly is nested between the foundation platform and the bridge assembly. The guide beam assembly is slidably engaged with both the foundation platform and the bridge assembly. The foundation platform is also equipped with a bridge propulsion locking device and a guide beam propulsion locking device. The bridge propulsion locking device is connected to the bridge assembly, and the guide beam propulsion locking device is connected to the guide beam assembly. The bridge provided by this utility model drives the guide beam to extend and retract along the foundation platform through the guide beam propulsion locking device, and drives the bridge body to extend and retract along the foundation platform and the guide beam through the bridge propulsion locking device. This enables the erection and retraction of the bridge. The structure is simple, the operation is convenient, the construction cycle is greatly shortened, and it can be reused, reducing construction costs. It is suitable for various complex working conditions.

[0018] (2) In this utility model, the guide beam assembly provides an intermediate support point for the main body of the bridge during its extension and contraction. This can effectively increase the extension length of the bridge while keeping the strength and stiffness of the bridge itself unchanged, thus ensuring the strength and stability of the bridge.

[0019] (3) In this utility model, the guide beam is driven to extend and retract along the foundation platform by the guide beam pushing and locking device, and the bridge body is driven to extend and retract along the foundation platform and the guide beam by the bridge pushing and locking device. No human intervention is required, which greatly improves the efficiency of bridge erection.

[0034] Example

[0035] See Figures 1-6 This embodiment provides a bridge, including a base platform 1, a bridge component 2, and a guide beam component 3. The bridge component 2 is retractably mounted on the base platform 1, and the guide beam component 3 is nested between the base platform 1 and the bridge component 2. The guide beam component 3 is slidably engaged with both the base platform 1 and the bridge component 2. In this embodiment, the base platform 1 is a stable working platform, serving as the foundation for installing the bridge component 2 and the guide beam component 3.

[0036] See Figure 5The guide beam assembly 3 includes a guide beam 3.1 and a guide beam guiding and limiting device 3.2. The guide beam 3.1 is slidably connected to the foundation platform 1 through the guide beam guiding and limiting device 3.2. In this embodiment, there is one guide beam 3.1 located in the middle of the foundation platform 1. Multiple guide beams 3.1 may also be provided, arranged parallel to each other along the length of the foundation platform 1, making the overall bridge structure more stable. Preferably, multiple sets of guide beam guiding and limiting devices 3.2 are evenly arranged along the length of the foundation platform 1. Each guide beam guiding and limiting device 3.2 includes a slider and guide wheels. The slider is fixedly mounted on the foundation platform 1, and guide wheels are provided at both ends of the slider. The slider slides against the bottom surface of the guide beam 3.1, and the guide wheels are in contact with the side of the guide beam 3.1 to limit the telescopic movement of the guide beam 3.1. More preferably, the guide beam guiding and limiting device 3.2 may also be a combination of rollers and guide wheels.

[0037] See Figure 5 The base platform 1 is provided with a guide beam pushing and locking device 5, which is connected to the guide beam 3.1 and is used to drive the guide beam 3.1 to slide telescopically relative to the base platform 1.

[0038] In this embodiment, the guide beam pushing and locking device 5 is disposed below the guide beam 3.1, and includes a base 5.1 and a driving device 5.2. The base 5.1 is fixed in a groove provided on the base platform 1, and the driving device 5.2 is provided on the base 5.1 and is connected to the guide beam 3.1. Preferably, see [reference needed]. Figure 7 and Figure 8 The drive device 5.2 includes a gear reducer, the output end of which is connected to a gear 5.2.1. The gear 5.2.1 meshes with a rack 5.2.2 on the bottom surface of the guide beam 3.1, thereby enabling the guide beam 3.1 to slide telescopically relative to the base platform 1. Preferably, the base 5.1 is also provided with a horizontal guide component 5.3 and a vertical guide component 5.4. The horizontal guide component 5.3 and the vertical guide component 5.4 are preferably guide wheels, which cooperate with the guide beam 3.1 to guide the guide beam 3.1. The drive form in this embodiment is not limited to a gear and rack structure; other drive forms, such as a winch and wire rope, can also be used.

[0039] See Figures 2-4 The bridge component 2 includes a bridge body 2.1 and connecting structures 2.2. The connecting structures 2.2 are located on both sides of the bridge body 2.1, and the two connecting structures 2.2 and the bridge body 2.1 cooperate to form a cavity. The guide beam 3.1 is located in the cavity and is slidably engaged with the bridge body 2.1. In this embodiment, preferably, see [reference needed]. Figure 6The connecting structure 2.2 is a frame structure and is fixedly connected to the main body of the bridge 2.1.

[0040] Preferred, see Figure 2 and Figure 5 A guide structure 2.3 is provided between the bridge body 2.1 and the guide beam 3.1. The guide structure 2.3 includes a slider mounted on the bridge body 2.1 and guide wheels at both ends of the slider. The slider engages with the top surface of the guide beam 3.1, and the guide wheels engage with the sides of the guide beam 3.1. The guide structure 2.3 serves two purposes: firstly, it cooperates with the guide beam guiding and limiting device 3.2 to guide and limit the telescopic sliding of the guide beam 3.1; secondly, it guides and limits the telescopic sliding of the bridge body 2.1 on the guide beam 3.1.

[0041] See Figure 1 or Figure 3 In this embodiment, a bridge guide assembly 2.4 is symmetrically arranged at the tail end of the bridge body 2.1 (the end closest to the retraction direction of the bridge body 2.1) along the extension direction of the bridge body 2.1. The bridge guide assembly 2.4 slides in conjunction with the base platform 1. Preferably, the bridge guide assembly 2.4 includes guide wheels disposed on the bridge body 2.1. Through the cooperation of the guide wheels with the base platform 1, the extension and retraction movement of the bridge body 2.1 relative to the base platform 1 is guided and limited.

[0042] In this embodiment, see Figure 1 and Figure 6 The base platform 1 is also equipped with a bridge propulsion locking device 4, which is connected to the bridge assembly 2 and is used to drive the bridge assembly 2 to telescopically move relative to the base platform 1 or the guide beam 3.1. Preferably, multiple sets of the bridge propulsion locking device 4 are provided, symmetrically arranged on both sides of the bridge assembly 2 along the telescopic direction of the bridge assembly 2; preferably, see [reference needed]. Figure 6 The bridge propulsion locking device 4 includes a base 4.1 and a drive device 4.2. The base 4.1 is fixed on the foundation platform 1, and the drive device 4.2 is disposed on the base 4.1 and connected to the connecting structure 2.2. Preferably, the drive device 4.2 includes a gear reducer, the output end of which is connected to a gear. A rack is provided on the side beam of the connecting structure 2.2, and the gear meshes with the rack to realize the telescopic movement of the bridge body 2.1.

[0043] Preferably, in this embodiment, the base 4.1 is further provided with a limiting device 4.3. The limiting device 4.3 includes a vertical limiting guide wheel 4.3.1 and a horizontal limiting guide wheel 4.3.2. The vertical limiting guide wheel 4.3.1 is disposed on the upper and lower surfaces of the side beam of the connecting structure 2.2 to limit the connecting structure 2.2 in the vertical direction. The horizontal limiting guide wheel 4.3.2 is disposed on the side of the side beam to limit the connecting structure 2.2 in the horizontal direction (referring to the direction perpendicular to the extension and contraction direction of the bridge body 2.1 in the horizontal plane).

[0044] See Figures 1-4 The guide beam assembly 3 further includes a support leg 3.3, which is telescopically disposed at the head of the guide beam 3.1 (near the end of the guide beam 3.1 extending outwards). The support leg 3.3 provides support for the guide beam 3.1. A driving device is provided between the support leg 3.3 and the guide beam 3.1. The driving device drives the support leg 3.3 to extend and retract vertically relative to the guide beam 3.1. The driving device is preferably a hydraulic cylinder.

[0045] Specifically, refer to Figure 1 , Figure 3 and Figure 4 The bridge erection steps provided in this embodiment are as follows:

[0046] Step 1: See Figure 1 Bridge component 2, guide beam component 3, bridge propulsion locking device 4 and guide beam propulsion locking device 5 are installed on the foundation platform 1, with guide beam component 3 located in the cavity below the main body of the bridge 2.1.

[0047] Step 2: When the bridge is ready for erection, the guide beam 3.1 is extended by the guide beam pushing and locking device 5. After the guide beam 3.1 has been extended, the guide beam pushing and locking device 5 locks the guide beam 3.1 (in this embodiment, when the guide beam 3.1 needs to be locked, the gear reducer stops working, and the gear meshes with the rack on the guide beam 3.1, thus locking the guide beam 3.1 and restricting its movement); after the guide beam 3.1 is locked, the support leg 3.3 below the guide beam 3.1 extends under the action of the drive device and contacts the ground, maintaining support to the ground, see [link to relevant documentation] Figure 3 .

[0048] Step 3: The bridge body 2.1 is pushed out along the guide beam 3.1 by the bridge pushing and locking device 4. After the bridge body 2.1 is in place, the bridge body 2.1 is locked by the connection structure 2.2 cooperating with the bridge pushing and locking device 4. (In this embodiment, when the bridge body 2.1 needs to be locked, the gear reducer stops working, and the gear meshes with the rack of the connection structure 2.2, thus locking the bridge body 2.1 and restricting its movement.) The bridge erection is complete. See [link to documentation]. Figure 4 .

[0049] The bridge can be pulled back by using the reverse operation steps.

[0050] The bridge provided by this utility model can be quickly erected and quickly withdrawn, with high work efficiency, reusable, and suitable for various complex working conditions.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
