Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, and in particular to a defect treatment device for box girder bridges. Background Technology

[0002] In the construction of long-span box girder bridges, the handling of concrete defects is a crucial step in ensuring bridge quality. Concrete defect handling typically employs a formwork system, where a moving mechanism suspends the formwork via ropes to move it to the construction location. However, in windy weather, the formwork is prone to swaying, making construction impossible and impacting the construction schedule. Furthermore, the moving mechanism requires a high degree of balance, increasing the cost of construction equipment. Utility Model Content

[0003] Therefore, it is necessary to provide a defect handling device for box girder bridges, which improves the stability of the manned platform and the balance of the device by improving the support mechanism and the manned mechanism.

[0004] This application provides a defect treatment device for box girder bridges, comprising:

[0005] A moving mechanism capable of moving along a first direction, the moving mechanism having a bearing surface;

[0006] A support mechanism is disposed on the bearing surface, the support mechanism extending out of the bearing surface at both ends along a second direction, the second direction being perpendicular to the first direction;

[0007] Two manned mechanisms are provided, with the manned mechanisms respectively installed at both ends of the support mechanism extending from the bearing surface; the top end of the manned mechanism is connected to the support mechanism, and the bottom end of the manned mechanism extends along a third direction, which is perpendicular to the first direction and the second direction; each manned mechanism is provided with multiple manned platforms spaced apart along the third direction.

[0008] In some other embodiments, the manned mechanism includes:

[0009] A first suspension frame, the top end of which is connected to the support mechanism, the bottom end of which extends in a third direction, and the first suspension frame is provided with at least one of the manned platforms.

[0010] The second suspension frame has its top end connected to the bottom end of the first suspension frame, and its bottom end extends in a third direction. The second suspension frame is provided with at least one of the manned platforms.

[0011] The second suspension frame protrudes from the first suspension frame in a direction closer to the other manned mechanism, and the manned platform is disposed on the portion of the second suspension frame that protrudes from the first suspension frame.

[0012] In some other embodiments, the first suspension frame and the second suspension frame are configured as an integral structure.

[0013] In some other embodiments, the manned mechanism further includes:

[0014] A staircase is provided on the outside of the first suspension frame and the second suspension frame; the staircase extends along the third direction.

[0015] In some other embodiments, the manned mechanism is detachably connected to the support mechanism.

[0016] In some other embodiments, the support mechanism includes:

[0017] Multiple support beams are spaced apart on the bearing surface along the first direction, and both ends of each support beam extend out of the bearing surface along the second direction. The manned mechanism is connected to each of the support beams.

[0018] In some other embodiments, the support mechanism further includes:

[0019] The inclined tie beams are located on the side of the support beam away from the moving mechanism, and the two inclined tie beams and the corresponding support beams form a triangular structure.

[0020] In some other embodiments, the support mechanism further includes:

[0021] A support frame is disposed on the side of the support beam away from the moving mechanism and located in the middle of the support beam; one end of the inclined beam is connected to the end of the support beam, and the other end is connected to the end of the support frame away from the support beam.

[0022] In some other embodiments, the support mechanism further includes:

[0023] A traction structure, one end of which is connected to the support frame and the other end of which is connected to the end of the support beam along the second direction, is used to pull the end of the support beam away from the manned mechanism.

[0024] In some other embodiments, the pulling structure is configured as a hand-operated hoist.

[0025] The aforementioned box girder bridge defect treatment device utilizes a moving mechanism that travels along the bridge deck, thereby moving the supporting mechanism. By installing personnel carriers at both ends of the supporting mechanism, defects on both sides of the box girder bridge's facade can be treated simultaneously, improving work efficiency. Furthermore, the two personnel carriers, located at opposite ends of the moving mechanism, act as counterweights, further enhancing the mechanism's balance. Moreover, by incorporating multiple vertically spaced personnel platforms on the personnel carriers, operators can stand on platforms at appropriate heights to treat defects at different elevations without needing to raise or lower the platforms. Compared to traditional rope-suspended basket structures, this device is less prone to swaying, improving adaptability to different construction environments. Attached Figure Description

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See Figure 1 , Figure 1 This illustration shows a structural schematic diagram of a box girder bridge defect treatment device provided in one embodiment of this application. This embodiment provides a box girder bridge defect treatment device for treating concrete defects on the exterior facade of a box girder bridge 100. Specifically, the box girder bridge 100 includes a box girder 110, a bridge deck 120, and a guardrail 130. The bridge deck 120 is located at the upper end of the box girder 110, and the bridge deck 120 and the box girder 110 are aligned along the front-to-back direction (…). Figure 1 The bridge deck 120 spans the river (perpendicular to the plane of the paper), with guardrails 130 positioned on both sides of the bridge deck 120. Generally, the width of the bridge deck 120 is greater than the width of the box girder 110.

[0040] The defect handling device for box girder bridge includes a moving mechanism 1, a supporting mechanism 2, and at least two manned mechanisms 3. The moving mechanism 1 is movable along a first direction and has a bearing surface 11. The supporting mechanism 2 is disposed on the bearing surface 11, and extends out of the bearing surface 11 at both ends along a second direction, which is perpendicular to the first direction. Manned mechanisms 3 are respectively disposed at the two ends of the supporting mechanism 2 extending out of the bearing surface 11. The top end of the manned mechanism 3 is connected to the supporting mechanism 2, and the bottom end of the manned mechanism 3 extends along a third direction, which is perpendicular to both the first and second directions. Multiple manned platforms 31 are spaced apart along the third direction for each manned mechanism 3. The first direction is specifically as follows... Figure 1 The front and back directions shown, the second direction is specifically as follows: Figure 1 The left and right directions shown, and the third direction specifically as shown Figure 1 The up and down directions are shown in the diagram.

[0041] In this embodiment, two manned mechanisms 3 are provided, one at each end of the support mechanism 2 extending from the bearing surface 11. It is understood that more than two manned mechanisms 3 may be provided, with two or more manned mechanisms 3 provided at one end of the support mechanism 2. In this case, the multiple manned mechanisms 3 should be arranged in a front-to-back direction.

[0042] The box girder bridge defect handling device provided in this application embodiment uses a moving mechanism 1 that moves along the bridge deck 120, driving the support mechanism 2 to move. By setting up manned mechanisms 3 at both ends of the support mechanism 2, defects on both sides of the box girder bridge 100 can be handled simultaneously, improving work efficiency. Furthermore, the two manned mechanisms 3, located at opposite ends of the moving mechanism 1, act as counterweights, further facilitating the balance of the moving mechanism 1. Moreover, by setting up multiple vertically spaced manned platforms 31 on the manned mechanism 3, operators can stand on platforms 31 at appropriate heights to handle defects at different heights without needing to raise or lower the manned platforms 31. Compared to traditional rope-suspended basket structures, this device is less prone to swaying, improving adaptability to the construction environment.

[0043] Specifically, the mobile mechanism 1 can use a flatbed trailer or other pallet truck as its walking system, as long as it has a flat bearing surface 11. The walking system can be moved by any type of powered vehicle such as a tractor or forklift, without the need for a dedicated engineering vehicle.

[0044] In some embodiments, the manned mechanism 3 includes a first suspension frame 32 and a second suspension frame 33. The top end of the first suspension frame 32 is connected to the support mechanism 2, and the bottom end of the first suspension frame 32 extends downward. The first suspension frame 32 is provided with at least one manned platform 31. The top end of the second suspension frame 33 is connected to the bottom end of the first suspension frame 32, and the bottom end of the second suspension frame 33 extends downward. The second suspension frame 33 is also provided with at least one manned platform 31. The second suspension frame 33 protrudes from the first suspension frame 32 towards another manned mechanism 3, and the manned platform 31 is located on the portion of the second suspension frame 33 that protrudes from the first suspension frame 32. During operation, the first suspension frame 32 faces the exterior of the bridge deck 120 and the guardrail 130, and the operator stands on the manned platform 31 on the first suspension frame 32 to perform defect repairs on the exterior of the bridge deck 120 and the guardrail 130. With the second suspension frame 33 facing the outer facade of the box girder 110, operators stand on the personnel platform 31 on the second suspension frame 33 to perform defect treatment on the outer facade of the box girder 110. By setting the second suspension frame 33 to protrude from the first suspension frame 32, it is adapted to the narrower box girder 110, allowing the second suspension frame 33 to be close to the box girder 110, thus making it easier for operators to treat the box girder 110.

[0045] Optionally, the first suspension bracket 32 ​​and the second suspension bracket 33 are configured as an integral structure to facilitate assembly and improve the connection strength between the two.

[0046] Specifically, the first suspension frame 32 and the second suspension frame 33 are configured as a frame structure, including multiple crossbeams and longitudinal beams. The manned platform 31 can be erected on the crossbeams, which allows for flexible selection of crossbeams of appropriate height for erecting the manned platform 31. The first suspension frame 32 and the second suspension frame 33 can share a portion of the longitudinal beams. For the second suspension frame 33, longer crossbeams can be used.

[0047] To facilitate operators climbing onto the manned platform 31, the manned mechanism 3 also includes a step ladder 34, which is located outside the first suspension frame 32 and the second suspension frame 33 and extends in the vertical direction.

[0048] In some embodiments, the manned mechanism 3 and the support mechanism 2 are detachably connected. During assembly, the manned mechanism 3 and the support mechanism 2 are assembled separately. Then, the support mechanism 2 is fixed to the moving mechanism 1. A crane or other lifting device is then used to lift the manned mechanism 3 to the left and right sides of the box girder bridge 100. Finally, the top of the manned mechanism 3 is connected and fixed to the support mechanism 2. After assembly, the lifting device can be removed, and the moving mechanism 1 can drive the manned mechanism 3 to perform operations without occupying the lifting device for an extended period.

[0049] The following is combined Figure 1 and Figure 2 The structure of support mechanism 2 will be described. Figure 2 A schematic diagram of the moving mechanism 1 and the support beam 21 provided in one embodiment of this application is shown.

[0050] In some embodiments, the support mechanism 2 includes multiple support beams 21, which are spaced apart on the bearing surface 11 in the front-to-back direction. Both ends of each support beam 21 extend out of the bearing surface 11 in the left-to-right direction. The personnel carrying mechanism 3 is connected to each support beam 21. The support beams 21 can be made of I-beams, which have high structural strength.

[0051] In this embodiment, four support beams 21 are provided. Of course, more or fewer support beams 21 may be provided depending on the support strength requirements. The specific number of support beams 21 is not limited here.

[0052] In some embodiments, the support mechanism 2 further includes a tie beam 22, which is disposed on the side of the support beam 21 away from the moving mechanism 1. The two tie beams 22 and the corresponding support beam 21 form a triangular structure to provide tension and fixation for the support beam 21, which helps to prevent the support beam 21 from deforming under the pressure of the carrying mechanisms 3 at both ends.

[0053] In some embodiments, the support mechanism 2 further includes a support frame 23, which is disposed on the side of the support beam 21 away from the moving mechanism 1 and located in the middle of the support beam 21; one end of the inclined beam 22 is connected to the end of the support beam 21, and the other end is connected to the end of the support frame 23 away from the support beam 21.

[0054] Optionally, the support frame 23 extends in the front-to-back direction, connecting multiple support beams 21 and connecting all the diagonal bracing beams 22 to one support frame 23, thereby connecting all the support beams 21 and all the diagonal bracing beams 22 into an integrated structure, thereby improving the structural strength of the entire support mechanism 2.

[0055] In some embodiments, the support mechanism 2 further includes a traction structure 24, one end of which is connected to the support frame 23, and the other end is connected to the end of the support beam 21 in the left-right direction, for pulling the end of the support beam 21 away from the manned mechanism 3. When the moving mechanism 1 needs to move, the traction structure 24 pulls the left and right ends of the support beam 21 upward, thereby slightly raising the support beam 21 and preventing it from colliding with the guardrail 130.

[0056] Specifically, the tensioning structure 24 can be configured as a hand-operated hoist. Of course, the tensioning structure 24 can also adopt other structural forms, as long as it can pull up the end of the support beam 21.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
