Background Technology

[0002] When upgrading the signal system on an operational railway line, new bridge cable troughs need to be added. The traditional construction method is to re-weld angle steel brackets on the bridge passing platform. This method has many problems, such as high risk of working at height, difficulty in obtaining work permits, difficulty in manual installation, inaccurate control of bracket installation height, and low construction efficiency. As a result, it is difficult to guarantee the installation quality of irregular brackets at the bridge passing platform. Utility Model Content

[0003] In view of this, the present invention provides an efficient and safe installation of a special-shaped bracket for cable troughs at bridge abutments, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objectives, this utility model provides an efficient and safe installation of a cable trough irregular-shaped bracket for bridge passing platforms, including a mounting frame, a mounting plate, and bolts. The mounting frame can be installed on the bottom support leg of the bridge passing platform. The mounting frame includes a connecting plate that is installed in a fitted state on the bottom support leg of the bridge passing platform and a support plate that can support the cable trough. The mounting plate is disposed on the side of the connecting plate and the support plate, and is used to connect the connecting plate and the support plate; Each of the mounting plate, connecting plate, and support plate has a bolt on its opposite side, used to fix the connecting plate and support plate onto the mounting plate.

[0005] In the aforementioned irregular-shaped bracket for cable troughs at a bridge passing platform, the mounting plate may optionally include a first mounting plate connected to a support plate and a second mounting plate connected to a connecting plate, wherein the first mounting plate and the second mounting plate are slidably engaged, and the first mounting plate can be suspended from the top of the bridge passing platform.

[0006] In the aforementioned irregular support for cable troughs at a bridge abutment, the mounting plate may optionally include a baffle. Each baffle is rotatably provided corresponding to both the first and second mounting plates, with the ends of the two baffles rotatably connected. The baffle corresponding to the second mounting plate can fit against the side of the bottom leg of the bridge abutment.

[0007] In the aforementioned irregular-shaped support for cable troughs at a bridge abutment, optionally, the end of the first mounting plate is provided with a rotating plate that can switch from a state parallel to the first mounting plate to a state perpendicular to the first mounting plate, for switching the orientation of the bolts connecting the first mounting plate and the support plate. The bolts are threadedly connected to the rotating plate. When the rotating plate is perpendicular to the first mounting plate, the bolts can suspend the first mounting plate to the top of the bridge abutment.

[0008] In the aforementioned irregular-shaped support for cable troughs at a bridge abutment, optionally, the first mounting plate has two parallel limiting plates on the side away from the support plate, and the second mounting plate has a sliding plate on the side away from the connecting plate that can slide between the two limiting plates. The width of the sliding plate is longer than the width of the limiting plates. When the rotating plate is perpendicular to the first mounting plate, the tail of the bolt can abut against the sliding plate to limit the distance between the first mounting plate and the second mounting plate.

[0009] In the aforementioned irregular-shaped support for cable troughs at a bridge abutment, optionally, when the rotating plate is parallel to the first mounting plate and the two baffles are parallel to the first mounting plate, the bolts can fasten the first mounting plate to the support plate.

[0013] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] like Figure 1 and Figure 2 As shown in Embodiment 1, a high-efficiency and safe cable trough support bracket for bridge passing platform includes a mounting frame 1, a mounting plate 2, and bolts 3. The mounting frame 1 can be installed on the bottom support leg of the bridge passing platform. The mounting frame 1 includes a connecting plate 1-1 installed in a fitted state on the bottom support leg of the bridge passing platform and a support plate 1-2 that can support the cable trough. Mounting plate 2 is disposed on the side of connecting plate 1-1 and support plate 1-2, and is used to connect connecting plate 1-1 and support plate 1-2; Bolt 3 is provided on each of the opposite surfaces between mounting plate 2, connecting plate 1-1 and support plate 1-2, for fixing connecting plate 1-1 and support plate 1-2 onto mounting plate 2.

[0015] To facilitate the installation of the cable trough and the bridge parking platform, the connecting plate 1-1 is attached to the bottom support leg of the bridge parking platform, and the support plate 1-2 is located on the other side of the bottom support leg of the bridge parking platform. The bolt 3 is passed through the connecting plate 1-1 and the support plate 1-2, so that the connecting plate 1-1 and the support plate 1-2 are clamped on the bottom support leg of the bridge parking platform. Then, the mounting plate 2 is placed on the side away from the support plate 1-2, and the bolt 3 is passed through the mounting plate 2, the connecting plate 1-1 and the support plate 1-2, so that the connecting plate 1-1 and the support plate 1-2 are fixedly installed on the mounting plate 2. At this time, the mounting bracket 1 is fixedly installed on the bottom support leg of the bridge parking platform. The other support legs of the bridge parking platform are all equipped with the mounting bracket 1 as described above. Then, the cable trough is placed on the support plate 1-2, and the connection between the cable trough and the bridge parking platform is completed. To ensure accurate height control during cable trough installation, when installing connecting plate 1-1 and support plate 1-2 with mounting plate 2, bolts 3 can be loosened first to control the sliding of the mounting frame on the bridge abutment support leg. Once the frame has slid to the appropriate height, bolts 3 can be tightened to complete the installation of mounting frame 1. After adjusting multiple mounting frames 1 to the same height as described above, the cable trough can be placed on support plate 1-2 to ensure accurate height control during cable trough installation.

[0016] like Figures 3 to 5 As shown, in Embodiment 2, the mounting plate 2 includes a first mounting plate 2-1 connected to the support plate 1-2 and a second mounting plate 2-2 connected to the connecting plate 1-1, and the first mounting plate 2-1 and the second mounting plate 2-2 are slidably engaged, and the first mounting plate 2-1 can be suspended on the top of the bridge passing platform.

[0017] To facilitate the adjustment of multiple mounting brackets 1 to a uniform height during cable trough installation, the first mounting plates 2-1 at both ends of the bridge waiting platform are suspended from the top of the platform. The distance between the first mounting plates 2-1 and the second mounting plates 2-2 is adjusted. The cable trough is then placed on the end supports 1-2 of the bridge waiting platform to support its ends. Subsequently, the distance between the first mounting plates 2-1 and the second mounting plates 2-2 on the other legs is adjusted so that the supports 1-2 on the other legs are in contact with the bottom surface of the cable trough, thus facilitating the adjustment of multiple mounting brackets 1 to a uniform height.

[0018] Mounting plate 2 also includes baffle 2-3, which is rotatably provided for both the first mounting plate 2-1 and the second mounting plate 2-2. The ends of the two baffles 2-3 are rotatably connected, and the baffle 2-3 corresponding to the second mounting plate 2-2 can fit against the side of the bottom support leg of the bridge abutment.

[0019] To ensure the mounting bracket 1 remains stable in the width direction when the first mounting plate 2-1 is suspended, a stabilizing plate 2-4 is fixedly mounted on the second mounting plate 2-2. The stabilizing plate 2-4 can contact the end face of the connecting plate 1-1. Loosen the bolts 3 between the second mounting plate 2-2 and the connecting plate 1-1 to ensure that the stabilizing plate 2-4 can detach from the end of the connecting plate 1-1. Rotate the second mounting plate 2-2 so that the stabilizing plate 2-4 faces the bottom of the connecting plate 1-1. Tighten the bolts 3 between the second mounting plate 2-2 and the connecting plate 1-1. Bolt 3 is inserted between the two, and the bottom of the stabilizing plate 2-4 is attached to the connecting plate 1-1, so that the second mounting plate 2-2 is kept in the rotated state. At this time, the baffle 2-3 corresponding to the second mounting plate 2-2 can be attached to the side of the bottom support leg of the bridge parking platform. By attaching the connecting plate 1-1, the support plate 1-2 and the baffle 2-3 to the bottom support leg of the bridge parking platform, the first mounting plate 2-1 is attached to the top of the bridge parking platform, so that the mounting frame 1 can maintain stability in the width direction when the first mounting plate 2-1 is suspended. To achieve the effect of adjusting the distance between the first mounting plate 2-1 and the second mounting plate 2-2, a baffle 2-3 is provided corresponding to both the first mounting plate 2-1 and the second mounting plate 2-2. The ends of the two baffles 2-3 are rotatably connected. By adjusting the included angle of the two baffles 2-3, the distance between the first mounting plate 2-1 and the second mounting plate 2-2 can be adjusted.

[0020] The end of the first mounting plate 2-1 is provided with a rotating plate 2-5 that can switch from a state parallel to the first mounting plate 2-1 to a state perpendicular to the first mounting plate 2-1. This rotating plate 2-5 is used to switch the orientation of the bolt 3 connecting the first mounting plate 2-1 and the support plate 1-2. The bolt 3 is threadedly connected to the rotating plate 2-5. When the rotating plate 2-5 is perpendicular to the first mounting plate 2-1, the bolt 3 can suspend the first mounting plate 2-1 to the top of the bridge abutment.

[0021] To achieve the effect of suspending the first mounting plate 2-1 on the top of the bridge passing platform, the end of the first mounting plate 2-1 is provided with a rotating plate 2-5 that can switch from a state parallel to the first mounting plate 2-1 to a state perpendicular to the first mounting plate 2-1. This rotating plate 2-5 is used to switch the orientation of the bolt 3 connecting the first mounting plate 2-1 and the support plate 1-2. The bolt 3 is threadedly connected to the rotating plate 2-5. First, the bolt 3 is loosened to separate it from the support plate 1-2. Then, the first mounting plate 2-1 is rotated so that the stabilizing plate 2-4 aligns with the bottom of the connecting plate 1-1. Next, the rotating plate 2-5 is rotated from a state parallel to the first mounting plate 2-1 to a state perpendicular to the first mounting plate 2-1. At this time, the bolt 3 faces the support plate 2-1, which makes it easier for the bolt 3 to hold the top of the bridge passing platform, allowing the first mounting plate 2-1 to be suspended on the top of the bridge passing platform.

[0022] The first mounting plate 2-1 has two parallel limiting plates 2-6 on the side away from the support plate 1-2. The second mounting plate 2-2 has a sliding plate 2-7 on the side away from the connecting plate 1-1, which can slide between the two limiting plates 2-6. The width of the sliding plate 2-7 is longer than the width of the limiting plates 2-6. When the rotating plate 2-5 is perpendicular to the first mounting plate 2-1, the tail of the bolt 3 can abut against the sliding plate 2-7 to limit the distance between the first mounting plate 2-1 and the second mounting plate 2-2.

[0023] To achieve overall stability when adjusting the distance between the first mounting plate 2-1 and the second mounting plate 2-2, the first mounting plate 2-1 is provided with two parallel limiting plates 2-6 on the side away from the support plate 1-2, and the second mounting plate 2-2 is provided with a sliding plate 2-7 that can slide between the two limiting plates 2-6 on the side away from the connecting plate 1-1. When adjusting the distance between the first mounting plate 2-1 and the second mounting plate 2-2, the sliding plate 2-7 slides between the two limiting plates 2-6, and the sliding plate 2-7 is in contact with both limiting plates 2-6, so that the distance between the first mounting plate 2-1 and the second mounting plate 2-2 remains stable. To maintain the distance between the first mounting plate 2-1 and the second mounting plate 2-2, the width of the sliding plate 2-7 is longer than the width of the limiting plate 2-6. When the rotating plate 2-5 is perpendicular to the first mounting plate 2-1, the tail of the bolt 3 can abut against the sliding plate 2-7. After the height adjustment is completed, the bolt 3 is rotated so that the tail of the bolt 3 abuts against the sliding plate 2-7, clamping the sliding plate 2-7 on the first mounting plate 2-1, thus maintaining the distance between the first mounting plate 2-1 and the second mounting plate 2-2. In order to keep the rotating plate 2-5 perpendicular to the first mounting plate 2-1, the tail of the bolt 3 can abut against the sliding plate 2-7, and the tail of the bolt 3 contacts the plane of the sliding plate 2-7, so that the bolt 3, the sliding plate 2-7 and the first mounting plate 2-1 are locked together.

[0024] When the rotating plate 2-5 is parallel to the first mounting plate 2-1 and the two baffles 2-3 are parallel to the first mounting plate 2-1, the bolts 3 can fasten the first mounting plate 2-1 to the support plate 1-2.

[0025] To facilitate subsequent welding of the cable trough to the bridge bypass, the second mounting plate 2-2 is rotated to be parallel to the support plate 1-2, the rotating plate 2-5 is rotated to be parallel to the first mounting plate 2-1, and the two baffles 2-3 are pulled to be parallel to the mounting plate 2. At this time, the bolts 3 on the rotating plate 2-5 correspond to the threaded holes on the support plate 1-2. The bolts 3 are connected to the support plate 1-2, so that the connecting plate 1-1, the support plate 1-2, and the mounting plate 2 are fixedly connected by the bolts 3, thus forming a stable connection between the connecting plate 1-1, the support plate 1-2, and the mounting plate 2. This facilitates the subsequent welding of the cable trough to the bridge bypass. At the same time, the support plate 1-2 supports the cable trough, which prevents the cable trough from shaking during welding and increases safety.

[0026] Compared to Embodiment 1, Embodiment 2 has the advantage that when adjusting the installation height of the cable trough, only the height of the mounting brackets 1 at both ends of the bridge waiting platform needs to be determined. The height of the other mounting brackets 1 can be determined by fitting them to the bottom surface of the cable trough, which reduces the number of times the height of the mounting brackets 1 on the bottom legs of the bridge waiting platform needs to be measured, thus improving construction efficiency.

[0027] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
