Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a trough type cable bridge. Background Art

[0002] In modern buildings and industrial facilities, trough cable trays are widely used as a key cable management solution for laying and protecting wires and cables. This type of cable tray usually consists of a frame and a removable cover, designed to provide a safe and orderly path for cables while ensuring that the cables are protected from environmental factors such as dust and moisture.

[0003] After searching the trough type cable tray disclosed in Chinese patent CN214100690U, it was found that the patent ensures the connection effect between the protective shell and the card plate by slidingly connecting the card plate to the protective shell, and then fixing the card plate with bolts, and conducts the heat to the thermal grease layer through the thermal conductive graphite sheet and then to the thermal conductive silicone sheet, and then conducts the heat to the copper plate through the thermal conductive mud for heat dissipation, thereby ensuring the heat dissipation effect of this cable tray.

[0004] However, the existing trough-type cable tray still has some shortcomings. When fixing the card plate with bolts, it is necessary to align the threaded holes on the protective shell and the card plate. Since this cable tray is provided with an alignment mechanism, it is more troublesome to install the bolts, resulting in low installation efficiency. When the cable needs to be inspected or repaired, the cover plate needs to be repeatedly disassembled and installed, which can easily cause the bolts to loosen or be damaged, further reducing the reliability of the seal and increasing maintenance costs and workload.

[0008] Furthermore, in order to position the top cover when the bridge frame shell and the top cover are connected and to facilitate fixing the top cover, the connecting mechanism includes a slide groove arranged on the top cover, the slide groove matches one end of the bridge frame shell, a support frame outside the bridge frame shell, a fixed block is fixed on the top of the support frame, a groove is arranged inside the fixed block, a telescopic spring is arranged inside the groove, one end of the telescopic spring is connected to the clamping column, and a clamping groove is arranged on the top cover, and the clamping groove matches the clamping column.

[0009] Furthermore, in order to limit the moving distance of the card block and prevent the card block from escaping from the groove and affecting the normal use of the card block, a connecting rod is connected to one side of the card column, and one end of the connecting rod passes through the fixed block and is connected to the limit block.

[0010] Furthermore, in order to fix the top cover and ensure the connection effect between the top cover and the bridge frame shell, a through hole is provided on the top cover, the through hole is provided on one side of the slot, a bolt is provided on the outside of the through hole, and the bolt passes through the through hole to be connected to the bridge frame shell.

[0011] Furthermore, in order to inspect the cables inside the bridge shell without disassembling the top cover and ensure the airtightness of the trough-type cable bridge, the closing mechanism includes an opening provided at the top of the top cover, an inspection cover is placed inside the opening, one side of the inspection cover and the top cover are connected by a hinge, a buckle is provided on the other side of the inspection cover, and a lock is provided on the top cover, and the buckle matches the lock.

[0012] Furthermore, in order to be able to measure the external temperature of the cable and to promptly remind the monitoring personnel to take action when the temperature is abnormal, so as to prevent the cable from catching fire due to excessive temperature, a temperature sensor is provided on the inner wall of the bridge shell. The temperature sensor is electrically connected to the controller, which is arranged on the outside of the bridge shell and has an antenna.

The card slot 307 matches the card column 306. A connecting rod 6 is connected to one side of the card column 306. One end of the connecting rod 6 passes through the fixed block 303 and is connected to the limit block 7. By setting a limit plate, the outward movement distance of the card column 306 can be limited to prevent the card block from being ejected from the inside of the groove 304, and it is convenient to move the card block by pulling the limit plate, making the movement of the card block easier. A through hole 8 is provided on the top cover 2, and the through hole 8 is provided on one side of the card slot 307. A bolt 9 is provided on the outside of the through hole 8, and the bolt 9 passes through the through hole 8 and is connected to the bridge frame shell 1.

[0028] like Figure 1-Figure 3 As shown, the closing mechanism 5 includes an opening 501 arranged at the top of the top cover 2, and the inspection cover 4 is placed inside the opening 501. One side of the inspection cover 4 is connected to the top cover 2 by a hinge 502. A buckle 503 is provided on the other side of the inspection cover 4. A lock 504 is provided on the top cover 2. The buckle 503 matches the lock 504. A temperature sensor 10 is provided on the inner wall of the bridge shell 1. The temperature sensor 10 is electrically connected to the controller 11. The controller 11 is arranged on the outside of the bridge shell 1. A wireless transmission module is provided in the controller 11, which can send signals to the monitoring end. An antenna 12 is provided on the controller 11. By setting the antenna 12, the distance range over which the controller 11 can send signals is expanded.

[0029] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0030] In actual application, by placing the cable inside the bridge housing 1, and then placing one end of the top cover 2 inside the slide groove 301, when the slot 307 on the top cover 2 moves to the block, under the action of the telescopic spring 305, the block will be placed inside the slot 307, and the top cover 2 can be preliminarily connected and fixed.
