[0046] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the drawings in the embodiments of the present application, and the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those skilled in the art without creative work on the basis of the embodiments of the present application shall belong to the protection scope of the present application.

[0047] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0048] like Figure 1 and Figure 4 As shown, a cable laying and fixing device comprises a trough box 1 for accommodating a cable 5, and a cover 2 for closing the trough box 1 is arranged above the trough box 1. A plurality of fixing components 3 for fixing the cable 5 are sequentially arranged in the trough box 1 along the laying direction of the cable 5.

[0049] As a specific implementation, the trough box 1 described in this embodiment includes a first web 11, and the left and right ends of the first web 11 are respectively provided with first wing plates 12 extending upward perpendicularly to the first web 11, and the first web 11 and the first wing plates 12 together form a U-shaped structure with an opening facing upward. The cover 2 includes a second web 21 located above the trough box 1, and the two ends of the second web 21 are respectively provided with second wing plates 22 extending downward perpendicularly to the second web 21, and the second wing plates 22 are located on the outside of the trough box 1. The second web 21 and the second wing plates 22 together form a U-shaped structure with an opening facing downward, and are buckled on the upper end of the trough box 1.

[0050] like Figure 2 , Figure 3 and Figure 6 As shown, the fixing component 3 includes a first locking rod 31 and a second locking rod 32, and the first locking rod 31 and the second locking rod 32 are arranged in a line along a direction perpendicular to the trough box 1, and the lower ends of the first locking rod 31 and the second locking rod 32 are respectively fixedly connected to the first web 11 of the trough box 1. As a specific embodiment, in this embodiment, the lower ends of the first locking rod 31 and the second locking rod 32 are respectively fixedly connected to the first web 11 of the trough box 1 by welding. A second clamping assembly for fixing the topmost layer of cables 5 and a plurality of first clamping assemblies for fixing the remaining layers of cables 5 are arranged between the first locking rod 31 and the second locking rod 32.

[0051] like Figure 6 As shown, the first clamping assembly includes a first clamping member 33 respectively located on the upper and lower sides of the clamped cable 5, one end of the first clamping member 33 is provided with a first avoidance portion 3313 for accommodating the first locking rod 31, and the other end of the first clamping member 33 is provided with a second avoidance portion 3314 for accommodating the second locking rod 32.

[0052] like Fig.10 As shown, the second clamping assembly includes a first clamping member 33 located at the lower side of the clamped cable 5 and a second clamping member 34 located at the upper side of the clamped cable 5. One end of the second clamping member 34 is provided with a third avoidance portion 3413 for accommodating the first locking rod 31, and the other end of the second clamping member 34 is provided with a fourth avoidance portion 3414 for accommodating the second locking rod 32.

[0053] like Figure 3 As shown, the upper ends of the first locking rod 31 and the second locking rod 32 extend through the second web 21 of the cover 2 to the upper side of the cover 2, and the second web 21 is provided with an escape hole for accommodating the first locking rod 31 and the second locking rod 32. The first locking rod 31 and the second locking rod 32 are respectively provided with locking nuts 4 on the upper side of the cover 2, and under the pressing action of the locking nuts 4, the cables 5 at the uppermost layer are clamped and fixed by the second clamping assembly, and the cables 5 at the remaining layers are clamped and fixed by the first clamping assembly.

[0054] As a specific implementation method, Figure 3 and Figure 5 As shown, in this embodiment, a first clamping cylinder 211 coaxially arranged with the first locking rod 31 and a second clamping cylinder 212 coaxially arranged with the second locking rod 32 are respectively provided on the lower side surface of the second web 21 of the cover 2. Under the locking action of the locking nut 4, the lower ends of the first clamping cylinder 211 and the second clamping cylinder 212 are both pressed against the second clamping piece 34 of the second clamping assembly.

[0055] Furthermore, if Figure 8 As shown, the first avoidance portion 3313 is a through hole that penetrates the first clamping member 33 in the up-down direction, and the second avoidance portion 3314 is an avoidance notch with an arc structure with the first avoidance portion 3313 as the center. When the first locking rod 31 is inserted into the first avoidance portion 3313, the first clamping member 33 can rotate around the first locking rod 31 in the tank box 1.

[0056] As a specific implementation, in this embodiment, both ends of the first clamping member 33 are semicircular structures, and the length of the first clamping member 33 is equal to the inner width of the trough box 1 .

[0057] Here, in the first clamping assembly, the opening direction of the second avoidance portion 3314 of the first clamping member 33 located at the lower side may be the same as or different from the opening direction of the second avoidance portion 3314 of the first clamping member 33 located at the upper side. Figure 7 As shown, in this embodiment, the opening direction of the second avoidance portion 3314 of the first clamping member 33 located at the lower side is different from the opening direction of the second avoidance portion 3314 of the first clamping member 33 located at the upper side.

[0058] By providing a through hole at one end of the first clamping member 33 and a relief notch at the other end, when installing the first clamping member 33, the first clamping member 33 can be firstly made parallel to the length direction of the trough box 1, and the first locking rod 31 can be inserted into the through hole as the first relief portion 3313, and then the first clamping member 33 can be moved up and down to a suitable height position, and then the first clamping member 33 can be rotated to make the second locking rod 32 snap into the relief notch as the second relief portion 3314. In this way, during installation, the cable 5 does not need to be moved or given up significantly, which is convenient for installation.

[0059] Furthermore, if Figure 7 and Fig.10 As shown, a plurality of arc-shaped clamping grooves for accommodating the cables 5 are evenly distributed along the length direction on the side of the first clamping member 33 and the second clamping member 34 facing the clamped cable 5 .

[0060] Furthermore, if Figure 8 As shown, the first clamping member 33 includes a first clamping plate 331 made of a rigid material and a first protective pad 332 fixedly arranged on the inner side of the first clamping plate 331 (with the side facing the clamped cable 5 as the inner side) in a detachable manner, the first protective pad 332 is made of an elastic material, and the clamping groove on the first clamping member 33 is arranged on the first protective pad 332.

[0061] As a specific implementation, the first protection pad 332 described in this embodiment is made of soft rubber material.

[0062] As a specific implementation method, Figure 8As shown, in this embodiment, the first clamping plate 331 is provided with a first mounting groove 3311 on the side facing the clamped cable 5, and the first protection pad 332 is provided in the first mounting groove 3311. The first protection pad 332 is provided with a first connecting block 3321 on the side facing away from the clamped cable 5, and a first mounting hole 3312 is provided on the bottom surface of the first mounting groove 3311. The first connecting block 3321 is inserted into the first mounting hole 3312 and is fixedly connected to the first clamping plate 331 by a first bolt 333. For example, as Fig. 9 As shown, the first clamping plate 331 is provided with a first bolt 333 that penetrates the first mounting hole 3312 along the width direction of the first clamping plate 331, and the first bolt 333 is fixedly connected to the first clamping plate 331 by a threaded connection, and the first connecting block 3321 is provided with a first connecting hole 3322 for accommodating the first bolt 333.

[0063] Exemplarily, three first connection blocks 3321 are disposed on the first protection pad 332 , and correspondingly, three first mounting holes 3312 corresponding to the first connection blocks 3321 are disposed on the first clamping plate 331 .

[0064] like Fig.11 As shown, the second clamping member 34 includes a second clamping plate 341 made of a rigid material and a second protective pad 342 fixedly arranged on the inner side of the second clamping plate 341 (with the side facing the clamped cable 5 as the inner side) in a detachable manner, and the second protective pad 342 is made of an elastic material, and the clamping groove on the second clamping member 34 is arranged on the second protective pad 342.

[0065] As a specific implementation, the second protection pad 342 described in this embodiment is made of soft rubber material.

[0066] As a specific implementation method, Fig.11As shown, in this embodiment, a second mounting groove 3411 is provided on the side of the second clamping plate 341 facing the clamped cable 5, and the second protection pad 342 is provided in the second mounting groove 3411. A second connecting block 3421 is provided on the side of the second protection pad 342 facing away from the clamped cable 5, and a second mounting hole 3412 is provided on the bottom surface of the second mounting groove 3411. The second connecting block 3421 is inserted into the second mounting hole 3412 and is fixedly connected to the second clamping plate 341 by a second bolt 343. Exemplarily, the second clamping plate 341 is provided with a second bolt 343 that penetrates the second mounting hole 3412 along the width direction of the second clamping plate 341, and the second bolt 343 is fixedly connected to the second clamping plate 341 by a threaded connection, and the second connecting block 3421 is provided with a second connecting hole 3422 for accommodating the second bolt 343.

[0067] Exemplarily, three second connection blocks 3421 are provided on the second protection pad 342 , and correspondingly, three second mounting holes 3412 corresponding to the second connection blocks 3421 are provided on the second clamping plate 341 .

[0068] like Fig.10 As shown, the third avoidance portion 3413 and the fourth avoidance portion 3414 on the second clamping member 34 are both through holes penetrating the second clamping member 34 in the up-down direction.

[0069] Furthermore, if Figure 3 and Fig.10 As shown, both ends of the second clamping member 34 along the length direction are respectively a plane, and the length of the second clamping member 34 is equal to the inner width of the trough box 1.

[0070] Furthermore, if Figure 3 As shown, a limiting boss 121 is provided at the upper end of the inner side surface of the first wing plate 12 (the side opposite to the two first wing plates 12 is the inner side), and the limiting boss 121 determines the upper limit position of the second clamping member 34 relative to the trough box 1.

[0071] Here, the reason for setting the limiting boss 121 is that when the cover 2 is in a locked state, each fixing component 3 will also be in a locked state under the pressing action of the cover 2, but once the cover 2 is opened, each fixing component 3 will be in an open state. During the laying process or in the future maintenance process, it is necessary to turn over and search the cables 5. If the limiting boss 121 is not provided, the turning and searching process will affect the fixing components 3 that have already completed the arrangement of the cables 5 nearby. By providing the limiting boss 121, when the cover 2 is opened, although the fixing components 3 are in an open state, the existence of the limiting boss 121 limits the range of movement of the fixing components 3, so when the cables 5 are turned over and searched, it will not affect the remaining fixing components 3.

[0072] Furthermore, in order to prevent the limiting boss 121 from affecting the installation of the first clamping assembly and the second clamping assembly, as shown in FIG. Figure 3 As shown, the cross section of the limiting boss 121 is a right triangle structure. The lower side of the limiting boss 121 is a limiting plane, and the inner side of the limiting boss 121 (the side opposite to the two limiting bosses 121 is the inner side) is a guiding inclined surface extending obliquely outward and upward.

[0073] Taking the installation process of the second clamping member 34 as an example, when installing the second clamping member 34, the edge of the second clamping member 34 is placed against the guide slope. At this time, pressing down the second clamping member 34 allows the second clamping member 34 to interact with the guide slope, thereby causing the second wing plate 22 to elastically deform, and the second clamping member 34 is able to move downward. After the second clamping member 34 is completely moved below the limiting boss 121, the second wing plate 22 will return to its original state under the action of its own elastic restoring force.

[0074] When arranging the cable 5, the operation process is as follows:

[0075] First, as Fig.12 As shown, the first locking rod 31 is inserted into the first avoidance portion 3313 of the first clamping member 33, and the first clamping member 33 is rotated so that the first clamping member 33 is parallel to the length of the trough box 1. At this time, the first clamping member 33 can move up and down from the gap between the cable 5 and the edge of the trough box 1.

[0076] Second, if Fig.13 As shown, the first clamping member 33 is moved downward along the gap between the cable 5 and the edge of the trough box 1 until the first clamping member 33 moves down to the bottom of the trough box 1 .

[0077] Third, if Fig.14 As shown, the first clamping member 33 is rotated to allow the second locking rod 32 to be clamped into the second avoidance portion 3314 of the first clamping member 33 .

[0078] Fourth, if Fig.15 As shown, the first locking rod 31 is inserted into the first avoidance portion 3313 of another first clamping member 33, and the first clamping member 33 is rotated to be parallel to the length of the trough box 1. Then the first clamping member 33 is moved downward until the first clamping member 33 is located above the bottom layer of cables 5.

[0079] Fifth, if Fig.16 As shown, the first clamping member 33 is rotated to allow the second locking rod 32 to be clamped into the second avoidance portion 3314 of the first clamping member 33 .

[0080] Sixth, repeat the operations from the first step to the fifth step until the first clamping member 33 in the second clamping assembly is installed.

[0081] Seventh, such as Fig.17 As shown, the second clamping member 34 is mounted on the first locking rod 31 and the second locking rod 32 so that the first locking rod 31 and the second locking rod 32 are respectively inserted into the third avoidance portion 3413 and the fourth avoidance portion 3414 of the second clamping member 34 .

[0082] Eighth, close the upper cover 2 and tighten the locking nut 4.

[0083] Other embodiments obtained by those skilled in the art by combining, splitting, reorganizing, etc. the embodiments of the present application on the basis of the embodiments provided in the present application do not exceed the protection scope of the present application.

The above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
