Description

Technical Field

[0001] The present invention relates to the technical field of cable structure construction, and particularly to a lug cable clamp. Background Art

[0002] With the development of modern long-span buildings towards lightweight, cable net structure systems are increasingly used in building structures. Generally, the structural stiffness of a cable net is smaller than that of a conventional steel structure. Under wind loads and snow loads commonly encountered in building structures, large deformations will occur. Due to the deformation of the cable, the cable clamp will also deform, resulting in the lug structure on the cable clamp no longer being in the vertical direction, while the tension on the lug is in the vertical direction. Thus, a bending moment will appear at the connection position between the lug and the cable clamp. Usually, in such cases, ribs in the direction perpendicular to the ear plate are added in the design to resist the bending moment, which leads to an increase in the size and weight of the cable clamp. When the number of such cable clamps is large, it will bring an additional load to the entire cable net structure, and the economy will decline; at the same time, when the additional bending moment is large, the safety of the ear plate will also be significantly reduced. This results in the structure of the cable clamp of the lug being prone to damage and having a short lifespan. Summary of the Invention

[0003] In view of this, the present invention provides a lug cable clamp, which is a device that keeps the lug in the vertical direction and prevents the connecting mechanism from being damaged by bending due to the inclination of the main body mechanism along with the cable.

Detailed implementation manners

[0022] The following describes exemplary embodiments of the present invention with reference to the accompanying drawings. Various details of the embodiments of the present invention are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, descriptions of well-known functions and structures are omitted below for clarity and conciseness.

[0023] The "upper" and "lower" indicating the relative position relationship in this article are both based on Figure 1 and Figure 2 the perspective of

[0024] The lug cable clip of the present invention includes a main body mechanism, a connecting mechanism, and a movable mechanism. Among them, through holes are provided on the main body mechanism, and the connecting mechanism sequentially passes through the movable mechanism and the through holes and then connects with the main body mechanism; at least part of the movable mechanism is disposed in the through holes, and the movable mechanism is movably connected to the main body mechanism.

[0025] When the lug cable clip is in use, the main body mechanism is connected to the cable. When the cable is tilted due to an external force, the movable mechanism slides in the through hole of the main body mechanism, so as to ensure that the connecting mechanism remains in the vertical direction, thereby avoiding the generation of bending moments between the various mechanisms of the lug cable clip, reducing unnecessary bending-resistant structures, and prolonging the service life of the lug cable clip.

[0026] The main body mechanism includes a cable clip body 1 and a cable clip cover plate 2. The cable clip body 1 and the cable clip cover plate 2 are connected by bolts 3, and the cable clip cover plate 2 is disposed below both ends of the cable clip body 1.

[0027] As Figure 3 shown, the middle part of the cable clip body 1 is a disc-shaped structure, and both ends of the cable clip body 1 are strip-shaped structures, and both ends of the cable clip body 1 are symmetrically arranged with the middle part as the symmetry center.

[0028] A first arc-shaped groove 4 is provided on the lower surface of the cable clip body 1, and a second arc-shaped groove 5 corresponding to the first arc-shaped groove 4 is provided on the upper surface of the cable clip cover plate 2; the through hole is provided in the middle part of the cable clip body 1 and penetrates the cable clip body 1.

[0029] As Figure 1 shown, the number of cable clip cover plates 2 is 2.

[0030] The number of the first arc-shaped grooves 4 is 2. The two first arc-shaped grooves 4 are respectively located at both ends of the lower surface of the cable clamp body 1, and the two first arc-shaped grooves 4 are symmetrically arranged with the through hole as the axis of symmetry.

[0031] The corresponding number of the second arc-shaped grooves 5 is 2. The two second arc-shaped grooves 5 are respectively located on the upper surface of the cable clamp cover plate 2, and the two first arc-shaped grooves 4 are symmetrically arranged with the through hole as the axis of symmetry.

[0032] The first arc-shaped groove 4 and the second arc-shaped groove 5 form a closed arc-shaped groove for connecting with the cable.

[0033] The inner wall surface of the through hole is smoothed, which helps the moving mechanism to rotate more freely in the through hole and reduces wear.

[0034] The inner wall of the through hole can be treated by methods such as hard chromium plating, which can not only improve the corrosion resistance but also reduce the friction coefficient. The inner wall of the through hole can also achieve the same purpose by bonding a mirror stainless steel plate.

[0035] The through hole includes a frustum-shaped first through hole 9 and a second through hole 12 that are connected and arranged from top to bottom.

[0036] The first end of the first through hole 9 is located on the upper surface of the cable clamp body 1, the second end of the first through hole 9 is located inside the cable clamp body 1, and the inner diameter of this first end is greater than the inner diameter of this second end; the first end of the second through hole 12 is located inside the cable clamp body 1, the second end of the second through hole 12 is located on the lower surface of the cable clamp body 1, and the inner diameter of this first end is less than the inner diameter of this second end.

[0037] The second end of the first through hole 9 is connected to the first end of the second through hole 12.

[0038] The diameter of the second end of the first through hole 9 is the same as the diameter of the first end of the second through hole 12.

[0039] The diameter of the first end of the first through hole 9 and the diameter of the second end of the second through hole 12 can be the same or different.

[0040] The moving mechanism includes a spherical washer 13. The spherical washer 13 has a structure with a larger upper part and a smaller lower part, and at least part of the spherical washer 13 is arranged in the first through hole 9.

[0041] By adjusting the depth of the spherical washer 13 entering the first through hole 9, the distance between the connecting plate 10 and the cable clamp body 1 is adjusted.

[0042] The material of the spherical washer 13 can be ordinary steel, bearing steel or other steels that meet the use requirements according to the working conditions. The surface of the spherical washer 13 can adopt processes such as heat treatment, hard chromium plating, and bonding lubricating materials to reduce the friction coefficient of the sliding surface.

[0043] Such asFigure 2 As shown, the connecting mechanism includes a suspension rod 6. The suspension rod 6 passes through the spherical washer 13 and the through hole and then is connected to the main body mechanism.

[0044] The suspension rod 6 and the spherical washer 13 can be integrally designed or detachably assembled.

[0045] One end of the suspension rod 6 is provided with a pin hole, and the other end of the suspension rod 6 is provided with a connecting plate 10. A pin shaft hole 11 is provided on the connecting plate 10; a split pin 7 is arranged in the pin hole, and the hexagon nut 8 can be prevented from falling off by the split pin 7.

[0046] The load to be transmitted can be connected to the connecting plate 10 through the pin shaft hole 11.

[0047] On the suspension rod 6, a hexagon nut 8 is also sleeved between the pin hole and the spherical washer 13. The suspension rod 6 is tightly connected to the main body mechanism through the hexagon nut 8.

[0048] The number of the hexagon nuts 8 can be one or more. When the suspension rod 6 and the spherical washer 13 are detachably assembled, the spherical washer 13 is fixed in the suspension rod 6 and the through hole through the hexagon nut 8. In addition, by adjusting the screwing depth of the nut 8, the spatial position of the pin hole 11 can be adjusted to digest the vertical displacement deviation generated in the previous construction.

[0049] When the lug cable clamp provided by the present invention is in use, first, the distance between the cable clamp main body 1 and the connecting plate 10 is determined according to actual needs. The spherical washer 13 is placed in the first through hole 9, and then the cable clamp main body 1 and the cable clamp cover plate 2 are separated by the bolt 3. After that, the cable is placed in the first arc-shaped grooves 4 at both ends of the cable clamp main body 1, and then the cable clamp cover plate 2 and the cable clamp main body 1 are fastened by the bolt 3, so that the cable is placed in the arc-shaped groove with closed surroundings at both ends formed by the first arc-shaped groove 4 and the second arc-shaped groove 5. At the same time, the load to be transmitted is fixed to the connecting plate 10, and thus the load can be transmitted. When the cable tilts due to an external force, the spherical washer 13 rotates freely in the first through hole 9, so as to ensure that the suspension rod 6 and the load are still in the vertical direction, thereby avoiding the generation of bending moments between the various mechanisms of the lug cable clamp, reducing unnecessary bending-resistant structures, and prolonging the service life of the lug cable clamp.

[0050] The above specific embodiments do not constitute a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
