Description

Technical Field

[0001] This utility model relates to the field of connection device technology, and in particular to a cable duct connection device between a bridge and a roadbed. Background Technology

[0002] With the further development of urbanization, the demand for electricity in cities is increasing, and the scale of cables along municipal roads is also gradually expanding. When cables cross bridges, they are generally laid in protective conduits under the pedestrian walkways. According to site surveys and relevant engineering design data, cable conduit laying is limited by the space of the pedestrian walkways on the bridge section and the length of the pedestrian walkways on the roadbed section after the bridge. Common problems at the connection between the bridge and roadbed sections include: large conduit width, inability to connect to cable manholes; significant changes in elevation at the connection section, making turning difficult for cable laying; and cable manhole covers located in the roadway, affecting traffic flow and hindering maintenance. Furthermore, current methods of connecting and assembling conduits using bolts cannot achieve simultaneous fixing of multiple conduits, greatly reducing construction efficiency. Utility Model Content

[0003] The technical problem this invention aims to solve is that traditional cable conduit connection methods have many inconveniences and may lead to loosening at the cable conduit connection, thereby affecting the stability and safety of the cable.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cable duct connection device between a bridge and a roadbed, comprising a Z-shaped duct group and two straight duct groups. The two straight duct groups are located at both ends of the Z-shaped duct group and are connected to each other by a connection mechanism. The connection mechanism includes a connecting plate located between the Z-shaped duct group and the straight duct group. Multiple connecting sleeves are provided on the connecting plate. Threaded rods are rotatably connected to both sides of the connecting plate and two guide rods are fixedly connected to the threaded rods located above and below the threaded rods, respectively. Multiple sets of first semicircular clamps and second semicircular clamps are threadedly connected to the threaded rods, and the first semicircular clamps and second semicircular clamps are located on both sides of the connecting sleeves, respectively.

[0005] As a further improvement of this utility model, both ends of the Z-shaped pipe assembly and one end of the two straight pipe assemblies are sleeved on the outside of the connecting sleeve and located between the first semicircular clamp and the second semicircular clamp.

[0006] As a further improvement of this utility model, a knob is fixedly connected to one end of the threaded rod, and a bearing seat that is fixedly connected to the connecting plate is rotatably connected to the other end of the threaded rod away from the knob.

[0007] As a further improvement of this utility model, both guide rods pass through multiple sets of first semicircular clamps and second semicircular clamps, and both the first semicircular clamps and the second semicircular clamps are slidably connected to the guide rods.

[0008] As a further improvement of this utility model, the threaded rod body is provided with multiple sets of bidirectional external threads, and the surface of the threaded rod body is provided with a forward thread at the first semicircular clamping plate and a reverse thread at the second semicircular clamping plate.

[0009] The beneficial effects of this utility model are:

[0010] (1) This utility model effectively solves the problem that the traditional cable pipe connection device has a large pipe arrangement width at the junction of bridge and roadbed and cannot be connected to the cable working well by adopting a combination design of Z-type pipe arrangement group and straight pipe arrangement group.

[0011] (2) The connection mechanism design of this utility model makes the connection of cable pipes more secure, avoiding cable stability and safety problems caused by loosening. Furthermore, through the combined use of the threaded rod and the semi-circular clamp, multiple cable pipes can be quickly and easily fixed at one time, significantly improving construction efficiency.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This utility model provides the following: Figure 1-3 The cable duct connection device between the bridge and the roadbed shown includes a Z-shaped duct group 1 and two straight duct groups 2. The two straight duct groups 2 are located at both ends of the Z-shaped duct group 1 and are connected to each other by a connection mechanism. The connection mechanism includes a connecting plate 3 located between the Z-shaped duct group 1 and the straight duct group 2. Multiple connecting sleeves 4 are provided on the connecting plate 3. Threaded rods 5 are rotatably connected to both sides of the connecting plate 3 and two guide rods 6 are fixedly connected to the connecting plate 3, located above and below the threaded rods 5 respectively. Multiple sets of first semicircular clamps 7 and second semicircular clamps 8 are threadedly connected to the threaded rods 5, and the first semicircular clamps 7 and second semicircular clamps 8 are located on both sides of the connecting sleeves 4 respectively.

[0020] like Figure 1 As shown, in this utility model, both ends of the Z-shaped pipe assembly 1 and one end of the two straight pipe assemblies 2 are sleeved on the outside of the connecting sleeve 4 and located between the first semicircular clamp 7 and the second semicircular clamp 8.

[0021] like Figure 3 As shown, in this utility model, one end of the threaded rod 5 is fixedly connected to a knob 9, and the end of the threaded rod 5 away from the knob 9 is rotatably connected to a bearing seat 10 that is fixedly connected to the connecting plate 3. Both guide rods 6 pass through multiple sets of first semicircular clamping plates 7 and second semicircular clamping plates 8, and both the first semicircular clamping plates 7 and the second semicircular clamping plates 8 are slidably connected to the guide rods 6. The threaded rod 5 is provided with multiple sets of bidirectional external threads. The surface of the threaded rod 5 is provided with a forward thread at the first semicircular clamping plate 7 and a reverse thread at the second semicircular clamping plate 8.

[0022] Working Principle: In practical implementation, this invention first places the Z-shaped pipe assembly 1 and the straight pipe assembly 2 in predetermined positions, ensuring that the Z-shaped pipe assembly 1 and the straight pipe assemblies 2 at both ends are correctly aligned with the connecting sleeve 4. Then, due to the bidirectional external thread design of the threaded rod 5, rotating the knob 9 on the threaded rod 5 causes multiple sets of first semicircular clamping plates 7 and second semicircular clamping plates 8 to move towards the connecting sleeve 4, thereby clamping the Z-shaped pipe assembly 1 and the straight pipe assembly 2, thus achieving uniform and firm fixation of the cable ducts. The guide rod 6 ensures that the first semicircular clamping plates 7 and second semicircular clamping plates 8 can move smoothly along the guide rod 6 during the clamping process, avoiding damage to the ducts caused by uneven clamping force. Finally, through the combined use of the threaded rod 5 and the first semicircular clamping plates 7 and 8, multiple cable ducts are quickly and simultaneously fixed, significantly improving construction efficiency and ensuring the stability and safety of the cables.
