The cable clamp is generally divided into two half cable clamps, the two half cable clamps can be oppositely combined and sleeved on the main cable through bolts, and the cable clamp can be connected with a sling. The cable clamp has the function of transmitting the load of the sling connected with the cable clamp to the main cable, and meanwhile, the extrusion force generated on the main cable by the bolt fastening force of the cable clamp is used for obtaining reliable friction force, so that the downward sliding force generated on the cable clamp by the sling is offset.

Wherein, in order to improve the strength of the connection between the first bolt seat 3 and the first half clamp 1, a first flat plate 32 is welded to the outer wall of the first half clamp 1. To increase the strength of the connection between the second bolt seat 4 and the second half clamp 2, a second flat plate 42 is welded to the outer wall of the second half clamp 2.

As shown in fig. 3-6, the first bolt seat 3 may further include a first sealing plate 33, and the first sealing plate 33 is welded between the first support 30 and the first plate 32, and is sequentially welded to the plurality of first standing plates 31; the second bolt seat 4 may further include a second closing plate 43, and the second closing plate 43 is welded between the second support 40 and the second plate 42, and is in turn welded to the plurality of second standing plates 41.

As shown in fig. 6, the connecting member 5 is an ear plate provided with a mounting hole 50, and the mounting hole 50 is used for connection with an external object.

Wherein, the external object can be an existing sling. When the connecting member 5 is an ear plate, the cable clamp structure of the present embodiment is a pin hinge type cable clamp.

In order to ensure the stability of the ear plate against external objects, the present embodiment preferably has a thickness not less than the wall thickness of the first half clip 1 and not less than the wall thickness of the second half clip 2.

The wall thickness of the first half clamp 1 and the wall thickness of the second half clamp 2 can be both 30-40 mm, and the thickness of the lug plate is not less than 60 mm.

In this embodiment, the mounting hole 50 of the ear plate may be further attached with a reinforcing plate 7, and the reinforcing plate 7 is provided with a circular hole which is communicated with the mounting hole 50.

As shown in fig. 6, the second half clamp 2 comprises a left arc panel 20, a middle arc panel 21 and a right arc panel 22 which are welded in sequence; the ear plate is welded to the outer wall of the middle cambered plate 21.

When the ear plate is welded on the outer wall of the middle arc panel 21, after the cable clamp structure of the embodiment is applied between the main cable and the suspension cable, the first half clamp 1 is located above the second half clamp 2, and thus the cable clamp structure of the embodiment is an up-down involutory pin hinge type cable clamp.

For a split pin hinge clip, the teeth 60 may be integrally formed with the second upright plate 41 when the second bolt seat 4 includes the second upright plate 41. And in order to improve the stability of the convex teeth 60, the thickness of the second vertical plate 41 connected with the convex teeth 60 may be equal to the thickness of the convex teeth 60 to stably support the convex teeth 60.

It should be noted that, in order to improve the welding convenience between the ear plate and the second half clip 2, there are various structural forms of the second half clip 2. For example, the second half clip 2 may include two half-arc panels, where the top of the ear plate is an arc surface, one of the half-arc panels of the second half clip 2, the top of the ear plate, and the other half-arc panel are connected in a smooth transition manner to form the second half clip 2, where a weld between the second half clip 2 and the ear plate is located between the half-arc panel and the side of the ear plate, and in practical applications, the weld is located at a stress concentration portion of the cable clip structure, so that the connection strength of the ear plate is insufficient, and the fatigue performance of the cable clip structure is seriously affected. Furthermore, even if a plurality of stiffening ribs are added between the half-cambered plate and the lug plate, the phenomenon of insufficient connection strength is difficult to compensate.

In this embodiment, the connecting block 210 and the middle arc panel 21 are integrally formed, and the ear plate is welded to the connecting block 210, so that the weld joint is prevented from being located at the stress concentration portion of the cable clamp structure, and the stress transmission between the second half clamp 2 and the ear plate is uniform.

Therefore, in this embodiment, the connecting block 210 integrally formed with the middle arc-shaped panel 21 can not only improve the welding convenience and stability between the ear plate and the middle arc-shaped panel 21, but also avoid the stress concentration position of the cable clamp structure at the weld joint position at the top of the ear plate, thereby ensuring that the joint of the ear plate and the second half clamp 2 has sufficient transverse bending rigidity, and effectively ensuring the tensile strength of the external object connected to the mounting hole 50 by the ear plate.

As shown in fig. 6, in order to improve the welding stability between the lug plate and the connection block 210, a welding groove 2100 is provided at the connection portion of the connection block 210 with the lug plate, and an inner wall of the welding groove 2100 is inclined inward from the groove opening to the groove bottom. Correspondingly, the top of the ear plate is provided with a blade part 51 matched with the welding groove 2100.

In order to further improve the connection strength of the ear plate, the connection block 210 is preferably made of a material with stronger strength, such as Z35 steel plate or forged steel.

In summary, the cable clamp structure of the present embodiment may be an up-down pin hinge cable clamp, which is formed by the first half clamp 1 and the second half clamp 2 being closed to each other and fixedly connected by a connecting bolt. Moreover, a first supporting piece 30, a first vertical plate 31 and a first flat plate 32 are fixed outside the first half clamp 1 by welding, and the outer walls of the first supporting piece 30 and the first half clamp 1 are welded by penetration angle welding. And a second support member 40, a second vertical plate 41, a second flat plate 42, a connecting block 210 and an ear plate are fixed outside the second half clamp 2 in a welding mode, wherein the welding seams among the outer wall of the second half clamp 2, the connecting block 210 and the ear plate are penetration welding seams.
