Description

Technical Field

[0001] The utility model relates to the technical field of cable bridge structures, in particular to a cable bridge with adjustable isolation cavity capacity. Background Art

[0002] In the design of electrical system bridges, it is a conventional design to lay power cables and control cables on the same-layer bridge. Usually, a metal partition is added in the middle of the same-layer bridge for separation. However, the metal partition is directly welded and fixed on the bridge and directly positioned in the middle, so that the available capacity of the power cables and control cables on the same-layer bridge is the same. However, when the actual project is executed, the number and capacity of power cables and control cables laid on the same-layer bridge are different, resulting in the need to calculate the capacity of the bridge based on a certain cable with a larger number of cables. In this way, the bridge capacity of the other cable is very empty, resulting in a waste of bridge capacity, larger bridge specifications, and increased costs.

[0003] For example, in a project, power cables and control cables share the same layer of bridge with metal partitions in the middle. The power cables require a capacity of 100mm width and the control cables require a capacity of 400mm width. Because the metal partitions are directly welded in the middle of the bridge, the bridge specifications need to select a bridge with half the capacity of 400mm according to the required capacity of the control cables, that is, this bridge needs to be selected as an 800mm width bridge. Originally, the required capacity only required a bridge with a width of 100+400=500mm, but it was actually enlarged by 300mm, and the capacity was enlarged by about 1 / 4 to 1 / 3. The cost was also increased by about 1 / 5 to 1 / 4 accordingly. For buildings with space limitations, more space is occupied and it is more likely to interfere with other buildings.

[0004] CN216625153U provides a cable tray with an isolation cavity, which solves the problem that the partition in the cable tray cannot be flexibly adjusted by opening a rectangular through hole at the bottom of the tray and arranging a slider in the rectangular through hole to connect with the partition. However, this patent only targets a tray produced in a specific way, and is not feasible for any tray. It is not practical, has few limitations, has a high production cost, cannot be installed quickly, is not very convenient to adjust the capacity left and right, and increases the installation workload. In addition, a number of sliders are used for left and right separation, and the sliders are not of equal length to the tray. The power and control cables cannot be completely isolated in the tray on the same floor, which will cause interference and fail to meet the requirements of the specifications.

[0005] CN219498834U provides a multi-tube equipment bridge, which achieves the effect of adjusting the space of the first placement cavity and the second placement cavity by setting the partition plate to be inserted into the limit rod and the bidirectional screw rod. However, this adjustment method only adjusts one end of the bidirectional screw rod, and the limit rod end only plays an upper and lower limit role, which can easily adjust the partition plate to a tilted state, thereby affecting the size of the placement cavity, squeezing and interfering with the cable, and affecting the use of the bridge. Utility Model Content

[0006] The utility model provides a cable bridge with adjustable isolation cavity capacity, which can adjust the capacity of the isolation cavity while making the partitions more firmly fixed and less prone to shifting and tilting, thereby avoiding affecting the capacity of the isolation cavity and squeezing and interfering with the cables.

[0008] In some embodiments, the cross bar is provided with a scale for adjusting the installation position of the partition.

The first component has a through hole in the horizontal direction. The cross bar passes through the through hole and then penetrates the partition. The first component has a side hole in the vertical direction. The second component passes through the side hole and presses against the cross bar for locking.

[0011] In some embodiments, the first component is a nut, and the second component is a screw with an inner tip.

[0012] In some embodiments, two ends of the cross bar penetrate through the two side plates of the bridge frame and extend outward along the side plates. Two ends of the cross bar are provided with threads, and nuts are screwed into the threads to fix the cross bar.

[0013] In some embodiments, the separator is a metal separator.

[0014] In some embodiments, the crossbars include two, which are respectively disposed at two ends of the bridge frame, and the locking structure includes two groups, which are respectively disposed at two ends of the partition.

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0031] In the design of electrical system bridges, it is a conventional design to lay power cables and control cables on the same bridge. Usually, metal partitions are added in the middle of the same bridge to separate them. In the current bridges, the metal partitions are directly fixed in the middle, so that the power cables and control cables on the same bridge can use the same capacity. However, when the actual project is executed, the number and capacity of power cables and control cables laid on the same bridge are different, which leads to the need to calculate the capacity of the bridge based on a certain type of cable with a larger number of cables. In this way, the bridge capacity of another type of cable is very empty, resulting in a waste of bridge capacity, larger bridge specifications, and increased costs. At the same time, in the existing bridges that can adjust the capacity of the isolation cavity, the partition is only fixed at one end, and the other end is only limited in the vertical up and down direction. Therefore, during use, when the bridge is subjected to external force, the partition will tilt, which will change the capacity of the isolation cavity. In severe cases, the cables will be squeezed, affecting the use of the bridge.

[0032] To solve the above problems, refer to Figure 1-8 The present embodiment provides a cable bridge with adjustable isolation cavity capacity, including an upper cover 1 and a bridge body 2. The bridge body 2 is a U-shaped groove that passes through from front to back. The upper cover 1 covers the opening of the U-shaped groove to form the bridge. A metal partition 3 is provided in the bridge. The metal partition 3 divides the interior of the bridge into two isolation cavities 4, which are used to accommodate power cables and control cables respectively.

[0033] Two cross bars 5 are arranged in the bridge frame at intervals along a direction perpendicular to the protected metal partition 3, respectively arranged at the two ends of the bridge frame, and the two ends of the cross bar 5 pass through the two side plates of the bridge frame and extend outward along the side plates, and the two ends of the cross bar 5 are provided with threads, and nuts are screwed into the threads to fix the cross bar.

[0034] Two locking structures 6 are provided on one side of the two ends of the metal partition 3 close to the cross bar 5 and correspond to the two cross bars 5 respectively. The locking structures 6 can be unlocked and locked on the cross bar 5 to fix the metal partition 3 to the cross bar 5.

[0035] Specifically, the locking structure includes a first component 61 and a second component 62. The first component 61 is fixed to the metal partition 3. The first component 61 has a through hole 611 in the horizontal direction. The cross bar 5 passes through the through hole 611 and then penetrates the metal partition 3. The first component 61 has a side hole 612 in the vertical direction. The second component 62 passes through the side hole 612 and presses against the cross bar 5 for locking.

[0036] Among them, the first component 61 adopts a nut with a threaded hole on the side, the threaded hole surface of the nut is welded to the metal partition, the threaded hole of the nut is the through hole 611, and the threaded hole is the side hole 612. The second component 62 adopts a screw with an inner point screw made of stainless steel material, and the screw with an inner point screw passes through the threaded hole and presses against the cross bar 5 for locking.

[0037] In the cable bridge of this embodiment, the metal partition 3 can be unlocked and locked on the cross bars 5 at both ends. When the isolation chamber 4 needs to be adjusted, the screw is loosened from the upper end, the metal partition 3 is moved left and right to the positioned position, and then the screw is tightened to push the screw against the cross bar 5 to fix it, thereby completing the installation of the bridge again. The cable bridge of this embodiment can not only adjust the capacity of the isolation chamber, thereby reducing the waste of space, but also the two ends of the metal partition 3 are fixed on the cross bar 5 one by one, so the metal partition 3 can be fixed more firmly, and will not be offset or tilted in actual working conditions to change the capacity of the isolation chamber 4 and cause the extrusion of the cable.

[0038] In order to accurately locate the adjustment position of the metal partition, the bridge can adjust the capacity of the two isolation chambers according to the specific capacity requirements of the power cable and the control cable. In this embodiment, the crossbar 5 is provided with a scale to adjust the installation position of the metal partition 3. When installing and adjusting the capacity of the isolation chamber 4, the specific scale can be located according to the specific capacity requirements of the cable, so as to accurately adjust the capacity of the isolation chamber 4. At the same time, the scale can further ensure that when the metal partition 3 is installed, it can be aligned without skewing.

[0039] The cable tray of this embodiment can adjust the capacity of the left and right isolation chambers 4 at will in a fixed width of the cable tray, and the metal partition 3 is firmly installed, the adjustment method is simple, and the installation is fast on site. When the required cable capacity is different, it is not necessary to calculate the volume of the cable tray with more capacity, and only the metal partition 3 needs to be adjusted to adjust the capacity of the isolation chamber 4, thereby reducing the space occupied, and completely separating the power cable and the control cable from each other without interference, meeting the requirements of relevant specifications.

[0040] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
