The specific content is as follows:

[0020] 1. By setting up the clamping assembly, when the steel strand needs to pass through the conical through-hole, by pulling the pull rod, the movement of the pull rod drives the movement of the sliding plate. Through the movement of the sliding plate, the movement of the fixed plate and the stabilizing rod can be driven. Through the movement of the stabilizing rod, the movement of the first clamping plate can be driven, so that the steel strand can pass through the conical through-hole. At the same time, the movement of the sliding plate squeezes the first spring, causing the first spring to deform. After the steel strand completely passes through the conical through-hole and the elastic cushion plate and the metal sealing ring are also inserted into the inside of the conical through-hole, by loosening the pull rod, the sliding plate returns to its original position under the action of the first spring. Through the movement of the sliding plate, the movement of the fixed plate and the stabilizing rod can be driven. Through the movement of the stabilizing rod, the movement of the first clamping plate can be driven, so that the first clamping plates on both sides can clamp and stabilize the steel strand, thus ensuring the stability of the steel strand.

[0021] 2. By setting up the conical through-hole, the elastic cushion plate and the metal sealing ring, through the outward expansion of the elastic cushion plate inside the conical through-hole, the sealing tube can seal the outer end of the conical through-hole, and at the same time, it can avoid the situation that the steel strand shakes violently due to the incomplete consistency between the size of the conical through-hole and the penetrated steel strand.

[0022] 3. By setting up the groove, the second damping block, the second spring and the second clamping plate, after the steel strand passes through the groove, the steel strand squeezes the second clamping plate. By the second clamping plate being squeezed, the second spring is squeezed, causing the second spring to deform. At the same time, the second spring is a compression spring in the prior art, so the second spring exerts a pressure on the second clamping plate, so that the second clamping plate plays an auxiliary role in clamping and stabilizing the steel strand, thus ensuring the stability of the steel strand once again.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-5 , the present invention provides a technical solution: an anchor structure for a bridge sling, including a body 1, and a groove 3 is opened inside the body 1; a plurality of second damping blocks 4 are symmetrically installed on both sides inside the groove 3, and the middle of the bottom surface of the second damping block 4 is fixedly connected with a second spring 5, and the bottom surface of the second spring 5 is fixedly connected with a second clamping plate 6; it also includes: a plurality of clamping assemblies 2 are arranged on one side surface of the body 1; wherein, the clamping assembly 2 includes a connecting rod 201 fixedly connected with the body 1, and the side surface of the connecting rod 201 far from the body 1 is fixedly connected with a sleeve 202; wherein, chutes 203 are symmetrically opened on both sides inside the sleeve 202, and a slide plate 204 is slidably connected inside the chutes 203. As Figures 1-5 shown, by setting the clamping assembly 2, an auxiliary effect of clamping and stabilizing the steel strand can be achieved, thereby improving the stability of the steel strand and avoiding the situation of the steel strand shaking. At the same time, after the steel strand passes through the groove 3, the steel strand will squeeze the second clamping plate 6. By the second clamping plate 6 being squeezed, the second spring 5 will be squeezed, so that the second spring 5 deforms. At the same time, the second spring 5 is a compression spring in the prior art, so that the second spring 5 will apply a pressure to the second clamping plate 6, so that the second clamping plate 6 will play an auxiliary role in clamping and stabilizing the steel strand, thereby ensuring the stability of the steel strand once again.

[0031] A fixing plate 205 is fixedly connected to the middle of the surface of the skateboard 204. On both sides of the bottom surface of the fixing plate 205, stabilizing rods 206 are symmetrically installed. A first clamping plate 207 is fixedly connected to the bottom surface of the stabilizing rod 206. First damping blocks 208 are symmetrically arranged inside the sleeve 202. A first spring 209 is fixedly connected to the middle of the bottom surface of the first damping block 208. The bottom surface of the first spring 209 is fixedly connected to the skateboard 204. A pull rod 210 is fixedly connected to the middle of the top surface of the skateboard 204. The pull rod 210 penetrates through the sleeve 202. The stabilizing rod 206 is slidably connected to the sleeve 202. As Figure 4 shown, by pulling the pull rod 210, the movement of the skateboard 204 is driven by the pull rod 210. Through the movement of the skateboard 204, the movement of the fixing plate 205 and the stabilizing rod 206 can be driven. Through the movement of the stabilizing rod 206, the movement of the first clamping plate 207 can be driven, so that the steel strand can pass through the tapered through-hole 7. At the same time, the movement of the skateboard 204 will squeeze the first spring 209, so that the first spring 209 deforms. Then, the steel strand is completely passed through the tapered through-hole 7. At the same time, after the elastic cushion plate 8 and the metal sealing ring 9 are also inserted into the tapered through-hole 7, by loosening the pull rod 210, the skateboard 204 returns to its original position under the action of the first spring 209. Through the movement of the skateboard 204, the movement of the fixing plate 205 and the stabilizing rod 206 can be driven. Through the movement of the stabilizing rod 206, the movement of the first clamping plate 207 can be driven, so that the first clamping plates 207 on both sides can clamp and stabilize the steel strand, thus ensuring the stability of the steel strand. At the same time, the first spring 209 is a rubber composite spring in the prior art.

[0032] A plurality of tapered through-holes 7 are formed in one side surface of the body 1. An elastic cushion plate 8 is fitted and connected inside the tapered through-hole 7. A metal sealing ring 9 is fixedly connected to the top surface of the elastic cushion plate 8. As Figure 5 shown, by the elastic cushion plate 8 expanding outwards inside the tapered through-hole 7, the sealing tube can seal the outer end of the tapered through-hole 7, and at the same time, it can avoid the situation that the sizes of the tapered through-hole 7 and the penetrated steel strand are not completely consistent and the steel strand shakes violently.

[0033] Working principle: Before using this kind of anchor structure for bridge suspension cables, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 5As shown in the figure, first, when the steel strand needs to pass through the tapered through-hole 7, by pulling the pull rod 210, the movement of the pull rod 210 drives the movement of the sliding plate 204. Through the movement of the sliding plate 204, the movement of the fixing plate 205 and the stabilizing rod 206 can be driven. Through the movement of the stabilizing rod 206, the movement of the first clamping plate 207 can be driven, so that the steel strand can pass through the tapered through-hole 7. At the same time, the movement of the sliding plate 204 squeezes the first spring 209, causing the first spring 209 to deform. After the steel strand completely passes through the tapered through-hole 7 and the elastic cushion plate 8 and the metal sealing ring 9 are also inserted into the interior of the tapered through-hole 7, by loosening the pull rod 210, the sliding plate 204 returns to its original position under the action of the first spring 209. Through the movement of the sliding plate 204, the movement of the fixing plate 205 and the stabilizing rod 206 can be driven. Through the movement of the stabilizing rod 206, the movement of the first clamping plate 207 can be driven, so that the first clamping plates 207 on both sides can clamp and stabilize the steel strand, thus ensuring the stability of the steel strand.

[0034] Secondly, by the outward expansion of the elastic cushion plate 8 inside the tapered through-hole 7, the sealing tube can seal the outer end of the tapered through-hole 7, and at the same time, it can avoid the situation where the sizes of the tapered through-hole 7 and the penetrated steel strand are not completely consistent and the steel strand shakes violently.

[0035] Finally, after the steel strand passes through the groove 3, the steel strand squeezes the second clamping plate 6. By the second clamping plate 6 being squeezed, the second spring 5 is squeezed, causing the second spring 5 to deform. At the same time, the second spring 5 is a compression spring in the prior art, so the second spring 5 exerts a pressure on the second clamping plate 6, so that the second clamping plate 6 plays a role in assisting in clamping and stabilizing the steel strand, thus ensuring the stability of the steel strand once again.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
