Description

Technical Field

[0001] The utility model belongs to the technical field of cable bridges, and in particular relates to a connection structure of a bridge. Background Art

[0002] Cable bridges are primarily used to support, protect, manage, and dissipate heat from cables and wires. To facilitate transportation and installation, they are typically cut into multiple sections and connected together using a connecting structure to create a cohesive whole, allowing cables or wires to be laid.

[0003] At present, the Chinese utility model with the publication number CN220156155U discloses a connection structure between cable bridges. During the actual installation of the bridge, due to the differences in the installation scenarios, the two sections of the bridge are often at different angles. However, the connection structure of the existing bridge is generally based on the angle between the two sections of the bridge, so it is cut and processed on site and cannot be freely adjusted. And when the bridges are connected, if there is a certain angle between the bridges, when the cables or wires laid inside the bridge are pulled, the cables or wires will easily slide toward the inner circle of the bridge and thus pile up together. Therefore, this bridge connection structure with an angle cannot directly pull and lay the cables or wires, and the cables or wires need to be manually sorted out. Therefore, it is more troublesome to install and has low practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a connection structure of a bridge, which has the advantages of being easy to freely adjust according to a variety of different angles of the two sections of the bridge and preventing cables or wires from piling up near the inner circle of the bridge, so that the cables or wires can be evenly laid out on the bridge.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: a connection structure of a bridge frame, including a first connecting frame plate, one end of the first connecting frame plate is slidably sleeved with a second connecting frame plate, a limiting slide groove is provided inside the second connecting frame plate, and a sliding rod slidably connected to the limiting slide groove is welded to one end of the first connecting frame plate close to the second connecting frame plate, and the internal thread of the sliding rod is connected to a limiting bolt clamped with the second connecting frame plate.

[0006] By adopting the above technical solution, the first connecting frame plate slides inside the second connecting frame plate according to the position of the bridge, thereby rotating to a variety of different angles, and the position is locked and fixed by limiting bolts, so that the ends of the first connecting frame plate and the second connecting frame plate that are away from each other are respectively connected and installed with bridges at two different angles, thereby improving the convenience of installation and facilitating practical use. By using a spacer plate to separate the cables or wires laid inside the first connecting frame plate and the second connecting frame plate, when pulling the cables or wires, the rotating shaft and the conical sleeve rotate inside the spacer plate, thereby reducing the friction when the cables or wires are dragged. This prevents the cables or wires from sliding toward the inner ring of the bridge and piling up together, thereby improving the efficiency of laying cables or wires on the bridge.

[0007] The utility model is further configured as follows: a spacer plate is welded inside the first connecting frame plate and inside the second connecting frame plate at one end away from the first connecting frame plate, a rotating shaft is rotatably connected inside the spacer plate, and conical sleeves are symmetrically fixedly sleeved at both ends of the surface of the rotating shaft, and the narrow end faces of the two conical sleeves are close to each other.

[0008] The above technical solution is adopted to prevent the cables or wires from sliding toward the inner circle of the bridge and piling up, thereby improving the efficiency of laying cables or wires on the bridge.

[0009] The utility model is further configured as follows: two ceiling screws are symmetrically welded to one end of the first connecting frame plate and the second connecting frame plate that are away from each other.

[0010] The above technical solution makes it easy to hoist the bridge connection structure so as to connect and install it with the bridge.

[0011] The utility model is further configured as follows: the bottom of the first connecting frame plate is rotatably connected to a ball that is slidably connected to the inside of the second connecting frame plate.

[0012] By adopting the above technical solution, the friction force of the first connecting frame plate sliding inside the second connecting frame plate is reduced, and the sliding stability is improved.

[0013] The utility model is further configured as follows: two connecting plates are symmetrically provided at the ends of the first connecting frame plate and the second connecting frame plate that are away from each other, and mounting screw holes are opened at the ends of the first connecting frame plate and the second connecting frame plate that are away from each other and the interior of the connecting plates, and mounting bolts are threadedly connected to the first connecting frame plate and the second connecting frame plate respectively through the mounting screw holes.

[0014] By adopting the above technical solution, the mounting bolts are passed through the interior of the mounting screw holes, so that the two ends of the mounting screw holes can be respectively installed on the bridge frame and one end of the first connecting frame plate and the second connecting frame plate, thereby connecting the bridge frames at both ends of the first connecting frame plate and the second connecting frame plate.

[0015] The utility model is further configured as follows: a non-slip sleeve is adhered to the surface fixing sleeve of the conical sleeve.

[0016] By adopting the above technical solution, the friction force on the surface of the conical sleeve is increased, thereby improving the anti-slip property of the cable when it is laid on the top.

[0017] The present invention is further configured such that surfaces of the first connecting frame plate and the second connecting frame plate are both electroplated with a corrosion-resistant layer.

[0018] By adopting the above technical solution, the corrosion resistance of the first connecting frame plate and the second connecting frame plate is improved, thereby being able to adapt to harsh environments for laying and protecting cables.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. The first connecting frame plate slides inside the second connecting frame plate according to the position of the bridge frame, thereby rotating to a variety of different angles, and is locked and fixed in position by limiting bolts, so that the ends of the first connecting frame plate and the second connecting frame plate that are away from each other are respectively connected and installed with bridge frames at two different angles, thereby improving the convenience of installation and facilitating practical use;

[0021] 2. By using spacers to separate the cables or wires laid inside the first and second connecting frames, when the cables or wires are pulled, the rotating shaft and the tapered sleeve rotate inside the spacers, thereby reducing the friction when the cables or wires are dragged. This prevents the cables or wires from sliding toward the inner ring of the bridge and accumulating together, thereby improving the efficiency of laying cables or wires on the bridge.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 、 Figure 2 A bridge connection structure includes a first connecting frame plate 1, one end of the first connecting frame plate 1 is slidably sleeved with a second connecting frame plate 2, a limiting slide groove 3 is provided inside the second connecting frame plate 2, and a sliding rod 4 slidably connected to the limiting slide groove 3 is welded to the end of the first connecting frame plate 1 close to the second connecting frame plate 2, and the internal thread of the sliding rod 4 is connected to a limiting bolt 5 that is clamped with the second connecting frame plate 2. The first connecting frame plate 1 slides inside the second connecting frame plate 2 according to the position of the bridge, thereby rotating to a variety of different angles, and is locked and fixed in position by the limiting bolt 5, so that the ends of the first connecting frame plate 1 and the second connecting frame plate 2 that are away from each other are respectively connected and installed with bridges at two different angles, thereby improving the convenience of installation and facilitating practical use.

[0029] refer to Figure 1 The first connecting frame plate 1 and the second connecting frame plate 2 are symmetrically welded with two ceiling screws 9 at one end away from each other. It is convenient to hoist the bridge connection structure so as to connect and install it with the bridge.

[0030] refer to Figure 1 The bottom of the first connecting frame plate 1 is rotatably connected to a ball 10 that is slidably connected to the inside of the second connecting frame plate 2. The friction of the first connecting frame plate 1 sliding inside the second connecting frame plate 2 is reduced, and the sliding stability is improved.

[0031] refer to Figure 1 、 Figure 2 Two connecting plates 11 are symmetrically provided at the ends of the first and second connecting frame plates 1 and 2 that are spaced apart from each other. Mounting screw holes 12 are provided at the ends of the first and second connecting frame plates 1 and 2 that are spaced apart from each other, as well as within the connecting plates 11. Mounting bolts 13 are threadedly threaded through the mounting screw holes 12 and are respectively bolted to the first and second connecting frame plates 1 and 2. The mounting bolts 13 pass through the mounting screw holes 12, allowing the ends of the mounting screw holes 12 to be mounted on the bridge and one end of the first and second connecting frame plates 1 and 2, respectively, thereby connecting the bridge at both ends of the first and second connecting frame plates 1 and 2.

[0032] A brief description of the usage process: By pushing the first connecting frame plate 1 to slide inside the second connecting frame plate 2, the first connecting frame plate 1 drives the sliding rod 4 to slide inside the limiting slide groove 3. Then, by rotating the limiting bolt 5 and engaging the sliding rod 4 with the thread, the limiting bolt 5 is affixed to the second connecting frame plate 2. The friction between the second connecting frame plate 2 and the limiting bolt 5 is used to lock and secure the first connecting frame 1. In this way, the end of the first connecting frame plate 1 away from the second connecting frame plate 2 can be rotated to a variety of different angles according to the position of the bridge, so that it can be connected to the bridge. The end of the second connecting frame plate 2 away from the first connecting frame plate 1 can be connected to another bridge, thus completing the installation of the bridge connection at two different angles.

[0033] Example 2:

[0034] refer to Figure 1 、 Figure 3 A bridge connection structure, wherein a spacer plate 6 is welded inside the first connecting frame plate 1 and inside the second connecting frame plate 2 at one end away from the first connecting frame plate 1. A rotating shaft 7 is rotatably connected to the interior of the spacer plate 6. Conical sleeves 8 are symmetrically fixedly sleeved on both ends of the surface of the rotating shaft 7, and the narrow end faces of the two conical sleeves 8 are close to each other. The cables or wires laid inside the first connecting frame plate 1 and the second connecting frame plate 2 are separated by the spacer plate 6. When the cables or wires are pulled, the rotating shaft 7 and the conical sleeve 8 rotate inside the spacer plate 6, thereby reducing the friction when the cables or wires are dragged. This prevents the cables or wires from sliding toward the inner ring of the bridge and piling up, thereby improving the efficiency of laying cables or wires on the bridge.

[0035] refer to Figure 3 The surface fixing sleeve of the conical sleeve 8 is adhered with an anti-skid sleeve 14. The friction force on the surface of the conical sleeve 8 is increased, and the anti-skid property when the cable is laid on the top is improved.

[0036] refer to Figure 1 The surfaces of the first connecting frame plate 1 and the second connecting frame plate 2 are both electroplated with a corrosion-resistant layer, thereby improving the corrosion resistance of the first connecting frame plate 1 and the second connecting frame plate 2, thereby being able to adapt to harsh environments for laying and protecting cables.

[0037] A brief description of the usage process: By welding spacer plates 6 to the interior of the first connecting frame plate 1 and the second connecting frame plate 2, cables or wires can be placed inside the spacer plates 6. The cables or wires are then placed at the center of the tops of the two tapered sleeves 8 by the inclined surfaces approaching each other. When the cables or wires are pulled, the rotating shaft 7 and the tapered sleeves 8 rotate inside the spacer plates 6, thereby reducing the friction when the cables or wires are pulled. At the same time, the spacer plates 6 can separate the cables or wires and prevent them from stacking together.
