Description

TECHNICAL FIELD

[0001] The utility model relates to cable bridge design technical field, especially, relate to a welding type ladder cable bridge. BACKGROUND

[0002] When laying cables, cable bridge layout wiring is often needed. Cable bridge is used for accommodating cables, providing stable working environment for cables, and facilitating overall layout of cables to reduce maintenance difficulty. Among them, the ladder cable bridge is a relatively common cable bridge type, which is characterized by simple structure, high heat dissipation efficiency, good air permeability, low cost and other advantages, and is widely used in large diameter, high voltage power and low voltage power cable scenes.

[0003] The traditional ladder cable bridge is fixedly connected between the two ends of the ladder beam and the two side plates by welding. This traditional design not only damages the protective layer on the surface of the ladder beam and the side plate due to welding, but also cannot be disassembled after welding, which increases the difficulty of transportation and the maintenance cost. UTILITY MODEL CONTENT

[0004] Therefore, the utility model provides a welding type ladder cable bridge, which realizes initial positioning between the ladder beam and the side plate by using the jack and the connector, and then realizes welding-free assembly by using the latch with a steel ball to string and lock the ladder beam and the side plate, so as to avoid damaging the protective layer on the surface of the ladder beam and the side plate due to welding, and the welding-free assembly can be disassembled at any time, which reduces the difficulty of transportation and the maintenance cost.

[0005] A welding type ladder cable bridge, comprising:

[0006] The side plate is radially distributed left and right symmetrically, and the bottom end of the side plate is provided with a first limiting plate and a second limiting plate extending along the radial direction; the first limiting plate and the second limiting plate are parallel to each other and are provided with a first pin hole; the bottom end of the side plate is also provided with a first jack and a second jack; the first jack and the second jack are arranged at intervals;

[0008] The latch is arranged between the side plate and the ladder beam; the latch comprises a stop portion, a rod body connected to the stop portion, a steel ball mounted on the end of the rod body away from the stop portion, and an elastic element accommodated in the rod body and connected to the steel ball; the rod body is arranged on the first pin hole and the second pin hole in the axial direction.

[0009] In the aforementioned weld-free ladder-type cable tray, during assembly, the ends of the ladder beams are respectively aligned with the side plates, so that the first connector is inserted into the first socket and the second connector is inserted into the second socket, thus completing the initial positioning of the ladder beams and side plates. Next, the rod of the pin is axially inserted into the first and second pin holes, so that the first connector, the second connector, the first limiting plate, and the second limiting plate are connected and fixed in series, preventing the ends of the ladder beams from detaching from the side plates. Through this design, the initial positioning between the ladder beams and side plates is achieved using the sockets and connectors, and then the ladder beams and side plates are locked together using pins with steel balls, thus achieving weld-free assembly. This avoids welding damage to the protective layer of the ladder beams and side plates, and allows for easy disassembly, reducing transportation difficulty and maintenance costs.

[0010] In one embodiment, the side plate has connection holes at both ends; these connection holes are used to connect with expansion joints. The connection holes allow for quick connection between the side plate and the expansion joint, reducing installation difficulty.

[0011] In one embodiment, the bottom end of the side plate is further provided with an inwardly bent support portion; the support portion is located above the ladder beam and abuts against the end of the ladder beam. The support portion can form a limit at the end of the ladder beam, further improving the connection stability between the end of the ladder beam and the side plate.

[0012] In one embodiment, the pin further includes a pull ring connecting to the stop. The pull ring facilitates the operator in pulling the pin, reducing the workload.

[0013] In one embodiment, the end of the ladder beam is located between the first limiting plate and the second limiting plate. The first and second limiting plates clamp and position the end of the ladder beam, improving the stability of the ladder beam and the side plate.

[0014] In one embodiment, the solderless ladder-type cable tray further includes a cover plate connecting the side plates; the cover plate covers the top of the two side plates. The cover plate provides protection above the side plates, preventing liquids or debris from falling directly onto the cables.

[0015] In one embodiment, the cover plate and the side plate are detachably connected by screws. This screw connection facilitates assembly and disassembly, reducing the difficulty of inspection and maintenance. Attached Figure Description

[0040] Example 1

[0041] like Figures 1 to 9 As shown, it is a weld-free ladder-type cable tray 100 according to Embodiment 1 of this utility model.

[0042] like Figures 1 to 4 As shown, the weld-free ladder-type cable tray 100 includes: a side plate 10, a ladder beam 20 connecting the side plate 10, and a pin 30 passing through the side plate 10 and the ladder beam 20. The side plate 10 and the ladder beam 20 together form a storage groove structure for accommodating cables, and the pin 30 is used to detachably lock the ladder beam 20 to the side plate 10.

[0043] The following text, combined with Figures 1 to 9 Further explanation is provided regarding the aforementioned weld-free ladder-type cable tray 100.

[0044] like Figure 1 and Figure 2 As shown, there are two side plates 10, which are symmetrically distributed in the radial direction.

[0045] like Figure 5 As shown, the bottom end of the side plate 10 is provided with a first limiting plate 11 and a second limiting plate 12 extending radially. The first limiting plate 11 and the second limiting plate 12 are parallel to each other and each is provided with a first pin hole 13. Figure 5 and Figure 6 As shown, the bottom end of the side panel 10 is also provided with a first socket 14 and a second socket 15. The first socket 14 and the second socket 15 are spaced apart.

[0046] Specifically, such asFigure 5 As shown, in this embodiment, the first insertion hole 14 is disposed adjacent to the first limiting plate 11, and the second insertion hole 15 is disposed adjacent to the second limiting plate 12. When manufacturing the side plate 10, the limiting plate can be obtained at the same time as forming the insertion hole by cutting, punching, or other methods. In other embodiments, the insertion hole and the limiting plate can also be disposed alternately.

[0047] Considering that in practical applications, cable trays need to have a clearance between two cable trays and be bridged together using expansion joints, and to facilitate installation and expansion, a combination of... Figure 1 and Figure 6 As shown, in this embodiment, the side plate 10 has connection holes 16 at both ends. The connection holes 16 are used to connect with the expansion joint. The connection holes 16 allow the side plate 10 to be quickly connected with the expansion joint, reducing the difficulty of installation.

[0048] like Figure 7 and Figure 8 As shown, both ends of the ladder beam 20 are provided with a first connector 21 and a second connector 22. Combined with... Figure 2 and Figure 3 As shown, the first connector 21 mates with the first socket 14, and the second connector 22 mates with the second socket 15. Meanwhile, as... Figure 8 As shown, both the first connector 21 and the second connector 22 are provided with a second pin hole 23.

[0049] In this embodiment, as Figure 3 As shown, the end of the ladder beam 20 is located between the first limiting plate 11 and the second limiting plate 12. The first limiting plate 11 and the second limiting plate 12 clamp and position the end of the ladder beam 20, improving the stability of the ladder beam 20 and the side plate 10. In other embodiments, a space for accommodating the first limiting plate 11 and the second limiting plate 12 can also be provided on the inner side of the ladder beam 20 (e.g., ...). Figure 8 As shown, a strip-shaped groove is provided at the bottom of the ladder beam 20. When the ladder beam 20 is connected to the side plate 10, the first limiting plate 11 and the second limiting plate 12 abut against the inner side of the ladder beam 20.

[0050] like Figure 9 As shown, the pin 30 includes: a stop portion 31, a rod body 32 connecting to the stop portion 31, a steel ball 33 installed at the end of the rod body 32 away from the stop portion 31, and an elastic member (not shown) housed within the rod body 32 and connected to the steel ball 33. Figures 1 to 3 As shown, the rod 32 is axially inserted through the first pin hole 13 and the second pin hole 23.

[0051] For ease of assembly and disassembly, in this embodiment, as follows: Figure 9As shown, the pin 30 may also include a pull ring 34 connecting to the stop portion 31. The pull ring 34 facilitates the operator in pulling the pin 30, reducing the workload.

[0052] Brief description of working principle:

[0053] like Figure 3 and Figure 4 As shown, during assembly, the ends of the ladder beam 20 are respectively connected to the side plate 10, so that the first insertion part 21 is inserted into the first insertion hole 14, and the second insertion part 22 is inserted into the second insertion hole 15. At this time, the initial positioning of the ladder beam 20 and the side plate 10 is completed. Next, the rod 32 of the pin 30 is inserted axially into the first pin hole 13 and the second pin hole 23, so that the first insertion part 21, the second insertion part 22, the first limiting plate 11, and the second limiting plate 12 are connected and fixed in series, so that the ends of the ladder beam 20 cannot be separated from the side plate 10.

[0054] To further clarify, in this embodiment, both the first limiting plate 11 and the second limiting plate 12 are located inside the side plate 10. Simultaneously, the ends of the first insertion portion 21 and the second insertion portion 22 are flush with the outer surface of the side plate 10, and the pin 30 is located inside the side plate 10. Therefore, after the cable tray is assembled, the outer side of the side plate 10 can remain flat, making it less prone to collision with external objects. Furthermore, the pin 30 is hidden inside the side plate 10, making it less likely to be touched and detached. It can be understood that in other embodiments, the first limiting plate 11 and the second limiting plate 12 may also be located outside the side plate 10, with the ends of the first insertion portion 21 and the second insertion portion 22 penetrating through the side plate 10 to extend to the outer side of the side plate 10, and the pin 30 located on the outer side of the side plate 10.

[0055] The aforementioned weld-free ladder-type cable tray 100 uses sockets and connectors to achieve initial positioning between the ladder beam 20 and the side plate 10. Then, the ladder beam 20 and the side plate 10 are connected and locked together using pins 30 with steel balls 33. This achieves weld-free assembly, avoids welding damage to the protective layer of the ladder beam 20 and the side plate 10, and can be disassembled at any time, making transportation easier and maintenance costs lower.

[0056] Example 2

[0057] like Figure 10 and Figure 11 As shown, it is a weld-free ladder-type cable tray 100 according to Embodiment 2 of this utility model.

[0058] The difference between this embodiment and Embodiment 1 is that: Figure 10 and Figure 11As shown, in this embodiment, the solderless ladder-type cable tray 100 further includes a cover plate 40 connecting the side plates 10. The cover plate 40 covers the top of the two side plates 10. The cover plate 40 can form a shielding protection above the side plates 10 to prevent liquids or debris from falling directly onto the cables.

[0059] In this design, the cover plate 40 can be connected to the side plate 10 by means of pins 30, screws, clips, etc.

[0060] For example, such as Figure 11 As shown, in this embodiment, the cover plate 40 and the side plate 10 are detachably connected by screws. This screw connection facilitates assembly and disassembly, reducing the difficulty of inspection and maintenance.

[0061] The other structures in this embodiment are the same as in Embodiment 1, and it can also achieve the beneficial effects of Embodiment 1.

[0062] Example 3

[0064] The difference between this embodiment and Embodiment 2 is as follows: Figure 10 and Figure 11 As shown, in this embodiment, the bottom end of the side plate 10 is further provided with an inwardly bent support portion 17. The support portion 17 is located above the ladder beam 20 and abuts against the end of the ladder beam 20. The support portion 17 can form a limit at the end of the ladder beam 20, further improving the connection stability between the end of the ladder beam 20 and the side plate 10.

[0065] In other embodiments, the support portion 17 may be disposed below the ladder beam 20 and abut against the end of the ladder beam 20. In this case, the support portion 17 forms a support structure for the end of the ladder beam 20, further improving the connection stability between the end of the ladder beam 20 and the side plate 10.

[0066] The other structures in this embodiment are the same as in Embodiment 2, and it can also achieve the beneficial effects of Embodiment 2.

[0067] 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.

[0068] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
