[0002] After the cable is put into use, it may be damaged and need to be repaired. Because the cable tray is located at a high position, it is necessary to manually use a ladder to climb to the vicinity of the cable tray where the damaged cable is located, remove the baffle on the cable tray, and repair the damaged cable. However, the space reserved above the cable tray is small, and for safety reasons, the cable tray is usually firmly connected to the baffle, and the baffle is not easy to remove. The reserved space is only enough for laying cables, and the cable repair is more difficult.

[0003] Moreover, during the use of cables, the cables are piled together and generate high heat. The heat accumulated between the cables is not easy to dissipate, and excessive heat in the cables increases the possibility of short circuit. Summary of the invention

[0004] In order to overcome the disadvantages that cables piled together generate high heat, the heat accumulated between the cables is not easy to dissipate, and the excessive heat of the cables increases the possibility of short circuit, the present invention provides a quick-connect protective bridge for cable laying and a method of use.

[0008] Furthermore, the bearing assembly also includes a filter; all bearing frames are equipped with a deformable filter, and there is a flow space between the filter and the bottom surface of the bearing frame.

[0009] Furthermore, the bearing assembly also includes limiting buckles; all bearing frames are fixed with a number of limiting buckles for fixing the filter screen; all limiting buckles located in the same bearing frame are equipped with the filter screen.

[0010] Furthermore, all the limiting buckles are truncated cone-shaped as a whole.

[0011] Furthermore, the bearing assembly also includes a lifting rod; all the bearing frames are provided with a slide groove II and a through groove; all the through grooves are slidably connected with the lifting rod, and the lifting rod slides in the slide groove II at the same time.

[0012] Furthermore, the bearing assembly also includes a cleaning plate; the lifting rod is slidably connected to the cleaning plate, and the cleaning plate is slidably connected to the bearing frame.

[0013] Furthermore, the cleaning plate is provided with chamfers.

[0014] Furthermore, a method for using a quick-connect protective bridge for laying cables includes the following steps: Step 1: first place the cable bridge on a pre-installed mounting frame, then use bolts to connect the mounting frame to the cable bridge, and place the cover plate on the cable bridge to complete the installation of the cable bridge; Step 2: by adding a bearing frame at the hollow part of the cable bridge, the hollow part of the cable bridge is shielded by the bearing frame. When the cable needs to be repaired, the bearing frame only needs to be flipped down to expose the cables in the cable bridge; Step 3: by opening an installation groove on the bearing plate, adding an installation card in the installation groove Buckle, when installing the load-bearing frame, just snap the load-bearing frame into the installation buckle to complete the completion of the load-bearing frame; Step 4: By adding positioning rings on the two load-bearing frames in all load-bearing components, by opening a slide groove Ⅰ on the load-bearing frame, adding a limiting plate in the slide groove Ⅰ, and by inserting the limiting plate into the two positioning rings, the two load-bearing frames connected by the positioning rings become a whole, so that the load-bearing frame will not flip downward when affected by the weight of the cable; Step 5: By adding a filter screen in the load-bearing frame, there is a flow space between the filter screen and the bottom surface of the load-bearing frame, so that the heat accumulated between the cables can be dissipated into the flow space.

After the cable is placed on the curved filter screen, the cable is made to present an undulating state as a whole, allowing more cables to stay in the bearing frame. After the bearing frame is completely flipped downward, the cable is allowed to hang down from the hollow part of the cable bridge, which is convenient for manual maintenance of the cable.

[0020] The present invention adds a cleaning plate to the lifting rod. After the filter is removed from the limiting buckle, the supporting frame is in an inclined state. The cleaning plate is pushed and pulled repeatedly by humans to push and clean the dust in the circulation space, thereby preventing dust from accumulating in the circulation space and affecting the heat dissipation of the cable.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] A quick-connect cable laying protective bridge, such as Figure 1-Figure 5 As shown, it includes a mounting plate 1, a cover plate 2 and a bearing plate 3; mounting holes are opened on the mounting plate 1 and the bearing plate 3; two mounting plates 1 and three bearing plates 3 are connected by bolts to form a cable tray; the cable tray is provided with a cover plate 2;

[0030] It also includes a bearing assembly; a plurality of bearing assemblies are installed in the cable tray; the bearing assembly is composed of two bearing frames 4; and the adjacent bearing plates 3 are rotatably connected with the bearing frames 4.

[0031] The bearing assembly also includes a mounting clip 5; all bearing plates 3 are provided with a plurality of mounting grooves; all mounting grooves on the bearing plates 3 are fixedly connected with mounting clips 5, the number of mounting clips 5 is consistent with the number of bearing frames 4, and the mounting clips 5 replace the bearing plates 3 and are rotatably connected with the bearing frames 4.

[0032] The bearing assembly also includes a positioning ring 6 and a limiting plate 7; positioning rings 6 are provided on opposite sides of all bearing frames 4; a slide groove Ⅰ41 is provided on the left bearing frame 4; a limiting plate 7 is slidably connected in the slide groove Ⅰ41, and the limiting plate 7 cooperates with the positioning ring 6 by plugging and unplugging.

[0033] The bearing assembly further includes a filter screen 101 ; all the bearing frames 4 are equipped with a deformable filter screen 101 , and there is a flow space between the filter screen 101 and the bottom surface of the bearing frame 4 .

[0034] The bearing assembly further includes a limiting buckle 102 ; four limiting buckles 102 are fixedly connected in all the bearing frames 4 ; and all the limiting buckles 102 in the same bearing frame 4 are equipped with a filter screen 101 .

[0035] All the limiting buckles 102 are in a frustum shape as a whole, which is convenient for the filter screen 101 to be disassembled and installed.

[0036] For the convenience of writing, the cable tray composed of the mounting plate 1 and the bearing plate 3 in the present invention is described and written as a cable tray.

[0037] Before carrying out the cable laying operation, it is necessary to complete the installation of the cable tray first. When installing the cable tray, first place the cable tray on the pre-installed mounting frame, then use bolts to connect the mounting frame to the cable tray, place the cover plate 2 on the cable tray, and complete the installation of the cable tray. After completing the installation of the cable tray, manually remove the cover plate 2 on the cable tray and start the cable laying operation. Manually lay the cable into the cable tray, remove the cover plate 2 and place it on the cable tray to complete the laying of this part of the cable.

[0038] After the cable starts to be used, it may be damaged and need to be repaired. Because the cable tray is located at a high position, it is necessary to manually use a ladder to climb to the vicinity of the cable tray where the damaged cable is located, remove the cover plate 2 on the cable tray, and repair the damaged cable. Such cable trays will be or a large part of them will be installed indoors, such as an indoor corridor of a building. At this time, their position is generally relatively close to the ceiling, and the space reserved above them is small. For safety reasons, the cable tray is usually firmly connected to the baffle, and the baffle is not easy to remove. The reserved space is only enough for laying cables, and the cable maintenance is relatively difficult. By adding a bearing frame 4 at the hollow part of the cable tray, the hollow part of the cable tray is shielded by the bearing frame 4. When the cable needs to be repaired, the bearing frame 4 only needs to be flipped down to expose the cables in the cable tray, which is convenient for manual maintenance.

[0039] By opening an installation groove on the bearing plate 3 and adding an installation buckle 5 in the installation groove, when installing the bearing frame 4, the bearing frame 4 can be completed by simply snapping the bearing frame 4 into the installation buckle 5, thereby reducing the installation strength of the bearing frame 4.

[0040] Taking into account that the cable has a certain weight, and the weight of the cable is applied to the supporting frame 4, the supporting frame 4 will flip downward due to the influence of the weight, thus affecting the use of the supporting frame 4. By adding positioning rings 6 to the two supporting frames 4 in all supporting components, by opening a slide groove Ⅰ41 on the supporting frame 4, and adding a limiting plate 7 in the slide groove Ⅰ41, and by inserting the limiting plate 7 into the two positioning rings 6, the two supporting frames 4 connected by the positioning rings 6 become a whole, so that the supporting frame 4 will not flip downward when affected by the weight of the cable.

[0041] Taking into account that during the use of cables, the cables are piled together and generate high heat, the heat accumulated between the cables is not easy to dissipate, and excessive cable heat will increase the possibility of short circuit. By adding a filter 101 in the load-bearing frame 4, there is a flow space between the filter 101 and the bottom surface of the load-bearing frame 4, so that the heat accumulated between the cables can be dissipated into the flow space, thereby reducing the accumulation of heat between the cables and the possibility of cable short circuit. By adding a limiting buckle 102 in the load-bearing frame 4, by installing the filter 101 on the limiting buckle 102, and by setting the limiting buckle 102 as a whole to be a truncated cone, it is convenient to plug and unplug the filter 101, and to disassemble and install the filter 101.

[0042] Example 2

[0043] On the basis of Example 1, Figure 5 As shown, the bearing assembly also includes a lifting rod 110; all the bearing frames 4 are provided with a slide groove II 42 and a through groove 43; all the through grooves 43 are slidably connected with the lifting rod 110, and the lifting rod 110 slides in the slide groove II 42 at the same time.

[0044] The bearing assembly further includes a cleaning plate 111 ; the lifting rod 110 is slidably connected to the cleaning plate 111 , and the cleaning plate 111 is slidably connected to the bearing frame 4 .

[0045] The cleaning plate 111 is provided with chamfers to improve the cleaning effect of the cleaning plate 111 .

[0046] A method for using a quick-connect protective bridge for laying cables, comprising the following steps:

[0047] Step 1: first place the cable tray on the pre-installed mounting frame, then use bolts to connect the mounting frame to the cable tray, place the cover plate 2 on the cable tray, and complete the installation of the cable tray;

[0048] Step 2: by adding a bearing frame 4 to the hollow part of the cable tray, the bearing frame 4 is used to cover the hollow part of the cable tray. When the cables need to be repaired, the bearing frame 4 can be turned down to expose the cables in the cable tray;

[0049] Step 3: By opening a mounting groove on the carrier plate 3 and adding a mounting buckle 5 in the mounting groove, when installing the carrier frame 4, the carrier frame 4 only needs to be snapped into the mounting buckle 5 to complete the installation of the carrier frame 4;

[0050] Step 4: by adding positioning rings 6 to the two carrying frames 4 in all the carrying components, by opening a slide groove Ⅰ41 on the carrying frame 4, adding a limiting plate 7 in the slide groove Ⅰ41, and by inserting the limiting plate 7 into the two positioning rings 6, the two carrying frames 4 connected by the positioning rings 6 become a whole, so that the carrying frames 4 will not turn down when affected by the weight of the cable;

[0051] Step 5: By adding a filter 101 in the supporting frame 4, there is a flow space between the filter 101 and the bottom surface of the supporting frame 4, so that the heat accumulated between the cables can be dissipated into the flow space.

[0052] Before laying the cable, a slide groove II 42 and a through groove 43 are provided on the load-bearing frame 4, and a lifting rod 110 is slidably connected in the through groove 43. The lifting rod 110 slides in the slide groove II 42 at the same time. The lifting rod 110 is manually pushed toward the middle of the load-bearing frame 4, and the lifting rod 110 slides in the slide groove II 42 and the through groove 43. During the movement of the lifting rod 110, the lifting rod 110 pushes upward, and the filter screen 101 is lifted up by the lifting rod 110, and the filter screen 101 begins to bend and deform. After the lifting rod 110 is manually pushed to the middle of the load-bearing frame 4, the lifting rod 110 stops moving, and then the laying of the cable is started. The cable is placed in the load-bearing frame 4. The filter screen 101 is in a bent state at this time. After the cable is placed on the bent filter screen 101, the cable is in an undulating state as a whole, so that more cables can stay in the supporting frame 4. When the cable is repaired, the limiting plate 7 is manually pushed so that the limiting plate 7 no longer connects the two supporting frames 4 connected by the positioning ring 6 as a whole. Then, the supporting frame 4 is manually pulled downward through the limiting plate 7, and the supporting frame 4 begins to flip downward. In the above manner, more cables can stay in the supporting frame 4. After the supporting frame 4 completes the downward flip, the cable is allowed to hang down from the hollow part of the cable tray, which is convenient for manual maintenance of the cable.

[0053] After the cable tray is used for a long time, a large amount of dust accumulates in the cable tray and the supporting frame 4. The dust blocks the filter 101 and the circulation space, affecting the heat dissipation of the cable. After the cable maintenance is completed, the filter 101 is manually removed from the limiting buckle 102, and the dust on the filter 101 is cleaned to prevent the dust from blocking the filter 101 and affecting the heat dissipation of the cable. A cleaning plate 111 is added to the lifting rod 110. After the filter 101 is removed from the limiting buckle 102, the supporting frame 4 is in an inclined state. The cleaning plate 111 is manually pushed and pulled repeatedly to allow the cleaning plate 111 to push and clean the dust in the circulation space to prevent the dust from accumulating in the circulation space and affecting the heat dissipation of the cable.

[0054] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
