Description

Technical Field

[0001] The present invention relates to the technical field of cable trays, and particularly to an anti-sway cable tray. Background Art

[0002] In modern power transmission and distribution systems, cable trays, as key facilities for supporting and carrying cables, have exposed many drawbacks in dealing with cable sway problems; currently, strong wind weather is a common cause of cable sway. In some coastal areas, open fields and other regions, strong winds frequently strike, and the wind force acting on the cable surface will cause large-amplitude sway of the cable. This sway will cause continuous friction between the cable and the cable tray, and both the cable and the cable tray are prone to wear and damage.

[0003] When most existing cable trays are designed, they mainly focus on the load-bearing and supporting functions of cables, lacking sufficient consideration for suppressing cable sway. Their internal structures are often relatively simple, such as trough-type cable trays; the cable will swing repeatedly in the trough, and only rely on the rigid structure of the cable tray itself to limit the sway amplitude of the cable, but the anti-sway effect brought by this structure is limited, and it is also easy to cause secondary damage to the cable due to rigid collision.

[0004] In summary, there is an urgent need for a new cable tray structure design that allows the cable to swing within a certain range to release the energy under the action of wind force, and at the same time enables the cable to return to the static state in time when swinging, so as to avoid wear caused by excessive cable sway and damage caused by rigid collision, and ensure the reliable operation of the cable; in view of this, we propose an anti-sway cable tray.

[0048] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0049] Please refer to Figures 1-12 , the above technical solutions of the present invention are described in detail through the following embodiments:

[0050] A cable anti-sway bridge, as shown in the structure of Figures 1-4 , includes an L-shaped bracket 1, and further includes:

[0051] A U-shaped support 2, which is detachably installed on the L-shaped bracket 1 by screws. As shown in the structure of Figure 4 , in this embodiment, the L-shaped bracket 1 is provided with an adjustment groove for installing screws, which can be adapted to the position adjustment during actual use.

[0052] An anti-sway part, as shown in the positional relationship of Figure 1 , includes a bracket assembly 3 detachably installed in the U-shaped support 2. The bracket assembly 3 includes a U-shaped base frame 31 with baffles 32 installed at both ends, and a cover plate 33 is installed between the two end baffles 32; a clamping seat unit 8 is slidably installed in the U-shaped base frame 31 along the swinging direction of the cable body 5, and at the same time, side baffle units 4 for blocking the swinging of the cable body 5 are provided on both sides of the clamping seat unit 8 in the U-shaped base frame 31.

[0053] In addition, in this application, as shown in Figure 1, Figure 5 and Figure 6 In the positional relationship shown, support blocks 6 are installed on the inner walls on both sides of the bracket assembly 3, and an airbag 7 is inserted between the two side blocking units 4. At the same time, it is necessary to keep the airbag 7 supported on the clamping seat unit 8 and the support blocks 6 on both sides, that is, after the bracket assembly 3 is installed and closed, the airbag 7 will maintain a horizontal position.

[0054] As Figures 6-11 shown in the structure, the side blocking unit 4 includes a bottom block 41 provided with a rotating groove 411, and a baffle 42 is rotatably installed in the rotating groove 411 through a rotating shaft 43. And in this embodiment, in order to obtain the elastic force for the two side baffles 42 to converge inward and obtain the deflection function of moving outward, as Figure 11 shown, a torsion spring groove 424 is provided at the bottom end of the baffle 42, and a torsion spring body 44 is sleeved on the rotating shaft 43 at the position of the torsion spring groove 424; when the cable body 5 does not swing, the two side baffles 42 will remain as Figure 6 shown under the action of the torsion spring body 44. When the cable body 5 swings, the two side baffles 42 will be deflected by the extrusion of the clamping seat unit 8, and this structure avoids the problem of cable damage caused by rigid contact friction.

[0055] It should be noted that in this embodiment, in order to avoid the rigid contact and provide a deflectable baffle 42, it will increase the swing amplitude of the cable. Although it can release the energy of the wind force, the large-range swing of the cable is not conducive to reliable operation; therefore, it is considered that while releasing the stress, it is necessary to keep the cable recover to rest in a timely and effective manner, that is, to avoid the problems of rigid collision wear and continuous excessive swing; therefore, as Figures 5-10 shown in the structure, an insertion port 423 is inserted on the baffle 42, and a convex block 422 is provided on the outer side of the baffle 42 above the insertion port 423. The airbag 7 horizontally passes through the two insertion ports 423 and maintains the positional relationship as Figure 6 shown, so that both ends of the airbag 7 can be horizontally lifted. When the clamping seat unit 8 swings with the cable body 5, after the two side baffles 42 are deflected, the convex block 422 will squeeze both ends of the airbag 7, and since the airbag 7 is in a fixed position, the inflation of the bladder part above the clamping seat unit 8 will occur after both ends are pressed.

[0056] In this embodiment, in order to better obtain the effect of the bladder part expanding and pressing the clamping seat unit 8, a pressing block 34 as Figure 9 shown is installed inside the cover plate 33, and a clamping groove 341 is provided on the pressing block 34. When the cover plate 33 is closed, the clamping groove 341 of the pressing block 34 will be clamped on the airbag 7, so that the airbag 7 at this part has an inflation tendency to press the clamping seat unit 8 downward.

[0057] In this embodiment, side sliding grooves 301 for inserting and mounting bottom blocks 41 and baffle plates 42 are provided on the U-shaped chassis 31, and a moving groove 302 is provided on the U-shaped chassis 31 between the two side sliding grooves 301; as Figure 12 shown in the structure, the clamping seat unit 8 includes a support plate 81 rotatably mounted with a clamping plate 82, and a cable slot 801 for clamping the cable body 5 is provided between the clamping plate 82 and the support plate 81. In order to facilitate maintaining the horizontal position of the clamping seat unit 8, a sliding block 811 is provided at the bottom of the support plate 81. In this embodiment, the sliding block 811 is of a cylindrical structure with a convex disk at the end, which is convenient for installation, so that the sliding block 811 is slidably mounted in the moving groove 302.

[0058] In Figure 10 shown in the structure, in this embodiment, in order to obtain a better deflection limiting function of the side blocking unit 4 and a larger deflection range, a limiting abutting block 421 bent outward is provided at the top of the baffle plate 42, and the retaining frame 32 is provided with a swinging cavity 321 for the limiting abutting block 421 to deflect and limit, so that the baffle plate 42 can be based on the limiting abutting block 421 against the swinging cavity 321 under the action of the torsion spring body 44, which is beneficial to assembly and maintaining structural stability. When not swinging, it is in the state as Figure 5 shown; in this embodiment, the cover plate 33 is rotatably mounted on one side retaining frame 32 and is fixed by inserting and mounting with an insertion rod 35 at the other end.

[0059] In this embodiment, since a deformation and movement process needs to be provided to cope with the problem of rigid wear, therefore, as Figure 10 、 Figure 11 shown in the structure, a recessed groove 311 is provided on the U-shaped chassis 31 outside the side sliding groove 301, and a mounting hole 412 is provided on the bottom block 41; a bolt 9 for threaded mounting in the mounting hole 412 is inserted in the recessed groove 311, and a spring 10 is sleeved on the bolt 9 inside the side sliding groove 301; when swinging occurs, the installed bolt 9 will extend outward simultaneously with the spring 10. Therefore, the recessed groove 311 is provided to provide this extension path to avoid affecting the installation of the U-shaped bracket 2.

[0060] The working principle of the cable anti-swing bridge in this embodiment is: as Figure 1 shown in the attached drawings, the anti-swing part can be quickly installed on the U-shaped bracket 2 through screws and fixed on the substrate to be installed through the L-shaped bracket 1; when assembling the anti-swing part, first slide the clamping seat unit 8 into the moving groove 302, and after centering, insert the side blocking units 4 into the two side sliding grooves 301 in sequence, and install the bolt 9 and the spring 10 to complete the fixation; then clamp each cable body 5 on the clamping seat unit 8 in sequence, install the support block 6, pass the airbag 7 through the insertion port 423 and keep it attached to the support block 6 and the clamping seat unit 8, and close the cover plate 33 so that the card slot 341 on the pressing block 34 snaps into the airbag 7. At this time, the airbag is in a non-expanded state;

[0061] When the wind acts on the cable body 5 and causes it to swing, the clamp unit 8 will be driven to swing left and right. At this time, the baffle 42 will be squeezed and deflected, and at the same time, the spring 10 will tend to be compressed. This part of the structure provides a deformation displacement space, avoiding rigid friction and also being able to provide a reset function. However, considering that the spring will cause it to continue to swing, although rigid friction is avoided, continuous swinging is also not conducive to the operation of the cable. Therefore, the present application is provided with an airbag 7 to achieve cooperation. The deflection of the baffle 42 will cause the convex block 422 to squeeze the airbag 7, and cause the bladder part above the clamp unit 8 to expand. The pressure brought by the expansion will force the cable to return to rest. At the same time, when the wind force is large, the deformation provided by the spring 10 and the airbag 7 can avoid the problem of the cable being rigidly damaged.

[0062] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0063] In addition, if there are descriptions such as "first" and "second" involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
