Description

Technical Field

[0001] This utility model relates to the field of cable trays, and more specifically, to a cable tray that is easy to disassemble and maintain. Background Technology

[0002] In power transmission and distribution systems, cable trays, as important facilities for carrying and protecting cables, are widely used in various fields such as construction, industry, and transportation.

[0003] Traditional cable trays typically use bolts to fasten the protective plates to the main body of the tray. This method has many drawbacks. On the one hand, during cable inspection, replacement, and other maintenance work, tools such as wrenches are needed to remove each bolt one by one, which is cumbersome and time-consuming, resulting in long maintenance times and significantly impacting work efficiency. Especially in scenarios requiring frequent maintenance, labor costs increase significantly. On the other hand, during long-term operation, the protective plates are prone to loosening due to environmental vibration and external impacts, which may even cause components to fall off, posing safety hazards. At the same time, bolts and other components are easily lost, further increasing the difficulty and cost of maintenance.

[0004] Therefore, it is necessary to redesign an easily disassembled and maintained cable tray to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a cable tray that is easy to disassemble and maintain.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable tray that is easy to disassemble and maintain includes a tray plate, a protective plate on the upper part of the tray plate, two through slots symmetrically opened on the upper end face of the protective plate, and mounting cavities opened on both sides of the tray plate. Two limiting blocks are symmetrically fixedly installed on the inner side wall of each mounting cavity. A fixing shaft is rotatably installed on the inner side wall of each mounting cavity. A fixing device is connected to each fixing shaft, and the output ends of the two fixing devices are respectively connected to the protective plate and to the two limiting blocks in corresponding positions.

[0008] In a preferred embodiment, each of the fixing devices has a winding wheel with a groove on one side and a fixed shaft movably connected in the groove. A steel rope is fixedly connected to the winding wheel, and one end of the steel rope passes through the corresponding mounting cavity and through groove and extends outward to install a locking block. A plurality of limiting grooves are provided on the side of the winding wheel away from the groove, and the limiting block is inserted into the corresponding limiting groove. A drive shaft is fixedly installed on one side of the winding wheel, and one end of the drive shaft passes through the inner wall of the corresponding mounting cavity and extends outward.

[0009] In a preferred embodiment, two card slots are symmetrically formed on the upper end face of the bridge deck plate, and the two card slots are respectively communicated with the two through slots, and the two clamping blocks are respectively abutted against the two card slots.

[0010] In a preferred embodiment, springs are fixedly connected to the inner side walls of each of the mounting cavities, and the two springs respectively abut against one side of the two winding wheels.

[0011] In a preferred embodiment, a rotating wheel is fixedly installed at one end of each of the transmission shafts away from the winding wheel.

[0012] In a preferred embodiment, each of the through slots is in a Chinese character 'zhong' shape.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting devices such as a fixing device, a card slot, and a spring, and through the linkage design of a rotating wheel, a winding wheel, and a steel wire rope, an operator only needs simple pressing and rotating actions to quickly complete the fixing and disassembly of the protection plate without using additional tools. Compared with the traditional cable bridge fastened by bolts, this operation method can shorten the single maintenance time and reduce the working intensity of maintenance personnel.

[0015] 2. By setting devices such as a spring, a limiting block, and a limiting slot, using the mechanical locking of the limiting block and the limiting slot, and cooperating with the elasticity of the spring, it effectively prevents the separation of the limiting block and the limiting slot. During normal use, the limiting block is embedded in the limiting slot to prevent the winding wheel from reversing, ensuring that the protection plate will not loosen due to factors such as vibration and external collision.

[0016] In summary, when the present utility model is in use, the operation is simple. Through the linkage of the rotating wheel, the winding wheel, and the steel wire rope, an operator only needs to press and rotate without tools to quickly complete the disassembly and assembly of the protection plate, greatly shortening the maintenance time and reducing the working intensity of maintenance personnel. At the same time, mechanical locking of the limiting block and the limiting slot is adopted, combined with the elastic reset of the spring to prevent their separation. During use, the reversal of the winding wheel can be avoided, ensuring the stability of the protection plate and guaranteeing the safe operation of the cable bridge.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-6 A cable tray that is easy to disassemble and maintain includes a cable tray plate 1, a protective plate 2 on the upper part of the cable tray plate 1, two through slots 13 symmetrically opened on the upper end face of the protective plate 2, and mounting cavities 6 respectively opened on the inner side of both sides of the cable tray plate 1. Two limiting blocks 11 are symmetrically fixedly installed on the inner side wall of each mounting cavity 6. A fixing shaft 8 is rotatably installed on the inner side wall of each mounting cavity 6. A fixing device is connected to each fixing shaft 8, and the output ends of the two fixing devices are respectively connected to the protective plate 2, and the output ends of the two fixing devices are respectively connected to the two limiting blocks 11 with corresponding positions.

[0026] Each fixing device has a winding wheel 9. A chute 14 is formed on one side of the winding wheel 9, and the fixed shaft 8 is movably connected in the chute 14. A steel rope 4 is fixedly connected to the winding wheel 9. One end of the steel rope 4 penetrates through the corresponding mounting cavity 6 and through slot 13 and extends outward to install a clamping block 5. A plurality of limiting slots 12 are formed on the side of the winding wheel 9 away from the chute 14, and the limiting block 11 is inserted into the corresponding limiting slot 12. A transmission shaft 10 is fixedly installed on one side of the winding wheel 9, and one end of the transmission shaft 10 penetrates through the inner side wall of the corresponding mounting cavity 6 and extends outward. A rotating wheel 3 is fixedly installed at one end of each transmission shaft 10 away from the winding wheel 9.

[0027] On the inner side wall of each mounting cavity 6, a spring 7 is fixedly connected, and the two springs 7 respectively abut against one side of the two winding wheels 9. The elastic characteristic of the spring 7 enables the limiting slot 12 on the winding wheel 9 to engage with the limiting block 11.

[0028] On the upper end face of the bridge plate 1, two card slots 15 are symmetrically formed, and the two card slots 15 are respectively communicated with the two through slots 13, and the two clamping blocks 5 respectively abut against the two card slots 15. Each through slot 13 is in a Chinese character 'zhong' shape. The Chinese character 'zhong' shaped through slots 13 symmetrically formed on the protective plate 2 provide a precise guiding path for the movement of the clamping block 5. The vertical section guides the clamping block 5 to vertically lift and lower, and the horizontal section allows the clamping block 5 to slide horizontally and be inserted into the card slot 15, ensuring the stable movement of the clamping block 5 during the fixing and disassembling process, avoiding deviation or jamming, improving the operation fluency. The card slot 15 on the bridge plate 1 is communicated with the through slot 13. When the clamping block 5 is inserted into the card slot 15, the protective plate 2 can be tightly connected to the bridge plate 1, enhancing the overall structural stability and preventing the protective plate 2 from loosening or falling off during use.

[0029] When the utility model is in use, during installation:

[0030] Pass the steel rope 4 and the clamping block 5 through the through slot 13 on the protective plate 2, and engage the clamping block 5 in the card slot 15 of the bridge plate 1.

[0031] Place the protective plate 2 on the upper part of the bridge plate 1, and ensure that the through slot 13 on the protective plate 2 is accurately aligned with the mounting cavities 6 on both sides of the bridge plate 1.

[0032] Press the rotating wheel 3. The rotating wheel 3 drives the transmission shaft 10 to push the winding wheel 9 to compress the spring 7. At this time, the fixed shaft 8 completely slides into the chute 14 on one side of the winding wheel 9, causing the limiting block 11 to脱离 the limiting slot 12 and解除 the locking restriction on the winding wheel 9.

[0033] Rotate the rotating wheel 3. Through the transmission shaft 10, drive the winding wheel 9 to rotate around the fixed shaft 8. As the winding wheel 9 rotates, the steel rope 4 wound thereon is gradually wound up, pulling the protective plate 2 to move downward and abut tightly against the bridge plate 1.

[0034] When the compression rotating wheel 3 stops, the elastic potential energy of the spring 7 pushes the winding wheel 9 to slightly reset. The limiting groove 12 on the side of the winding wheel 9 rotates to the position corresponding to the limiting block 11. The limiting block 11 is inserted into the limiting groove 12 to prevent the winding wheel 9 from rotating in the opposite direction, thus completing the firm fixation of the protective plate 2 on the cable tray plate 1.

[0035] Removal of protective plate 2:

[0036] First, compress the take-up reel 9 so that the limiting block 11 on the side of the take-up reel 9 disengages from the limiting groove 12, thereby releasing the lock on the take-up reel 9.

[0037] Reverse rotation wheel 3 drives take-up wheel 9 to rotate in the opposite direction, steel rope 4 is released, and locking block 5 loses the tension of steel rope 4 and exits from locking slot 15.

[0038] Align the locking block 5 with the through slot 13 and disengage it from the through slot 13. The protective plate 2 will lose its connection with the cable tray plate 1. The protective plate 2 can be directly lifted to repair the cables inside the cable tray.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
