Description

Technical Field

[0001] The utility model relates to the technical field of stay cable anchor protection, in particular to an anchor protection cover. Background Art

[0002] Cable-stayed bridges, thanks to their impressive spanning capacity, have become the predominant type of long-span bridge. The cable-stayed cables are the primary load-bearing components of cable-stayed bridges. Cable anchors are anchoring devices that ensure the reliable transmission of deck loads to the cables. Anchorage covers act as a safety barrier, protecting the cable anchorages from environmental corrosion. These covers play a crucial role in ensuring the structural safety of cable-stayed bridges.

[0003] At present, conventional anchor protection covers are connected to the anchors through annular structural bolts at the edge of their openings to achieve coverage and fixation of the anchors. However, although the anchor protection cover is fixed to the surface of the anchor by bolts, there is still a gap between the two, resulting in an inability to form a closed space inside the anchor protection cover. The inclined cable anchor will still be affected by environmental erosion. In case of rain, rainwater will enter the interior of the protection cover through the gap at the connection between the anchor protection cover and the anchor, which is not conducive to the protection of the inclined cable anchor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention proposes an anchor protection cover to solve the above problems.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] The anchor protection cover provided by the utility model comprises:

[0007] The protective cover body has an open bottom end and a sealing ring body is provided at the edge of the open end. The bottom side of the sealing ring body is provided with a ring groove. A sealing ring piece is installed in the ring groove for sliding up and down. The bottom side of the sealing ring piece is provided with a sealing layer and a spring is connected between the top side and the top wall of the ring groove. The spring can provide elastic force to push the sealing ring piece out of the bottom of the ring groove. The outer side of the sealing ring body is uniformly distributed with a plurality of insertion holes along the circumference. The bottom periphery of the sealing ring body is provided with a mounting ring body, and the mounting ring body is provided with a plurality of bolt holes.

[0008] A limiting column is slidably inserted into each of the insertion holes. When the limiting column is inserted into the insertion hole, it can press the sealing ring against the upper side thereof and compress the spring.

[0009] Furthermore, an inner wall of the annular groove on one side away from each insertion hole is provided with an end groove corresponding to each insertion hole, and the inner end of the limiting column can be inserted into the corresponding end groove through the insertion hole.

[0010] Furthermore, a sealing rubber ring is arranged around the limiting column.

[0011] Furthermore, the outer end of each of the limiting columns is respectively provided with an abutment block, and a control ring is coaxially installed on the outer side of the sealing ring body. The outer wall of the control ring is evenly distributed with a plurality of abutment teeth, and the number of the abutment teeth corresponds to the limiting column. One side of the rotation direction of the abutment teeth is smoothly connected with the outer wall of the control ring, and the other side is tilted outward and arched, and a limiting protrusion is provided on the edge of the side.

[0012] Furthermore, a handle is provided on the outer side of the control ring.

[0013] Furthermore, the outer wall of the control ring is provided with a sleeve, a positioning column is slidably inserted into the sleeve, and a positioning hole for inserting the positioning column is opened on the mounting ring body. When the positioning column is inserted into the positioning hole, each of the abutment blocks will be pushed outward along the inclined slope of the abutment teeth to move the inner end of the limit column out of the ring groove.

[0014] It can be seen from the above technical solution that the anchor protection cover provided by the utility model:

[0015] 1. After the mounting ring body is connected and fixed to the mounting position of the anchor, the sealing ring piece will be pushed toward the surface of the anchor under the elastic force of the spring, so that the sealing layer fully fits the surface of the anchor, so that the connection between the protective cover and the anchor is sealed and in contact with each other, which is conducive to maintaining the sealing inside the protective cover and improving the protection effect of the inclined cable anchor; the sealing ring piece is pressed into the ring groove by the limiting column, which can prevent the sealing ring piece from being pushed apart by the spring during the bolt connection of the connection between the mounting ring body and the anchor, which is conducive to reducing the difficulty of installing the protective cover and facilitating installation;

[0016] 2. By rotating the control ring, the abutment blocks of each limit column can be pushed outward by the corresponding push teeth, and the abutment blocks will be pulled outward along the inclined slope of the push teeth, thereby pulling the limit column outward. When the abutment blocks move to the highest point where the push teeth are arched outward, they will abut against the limit protrusions to limit the position. Only by rotating the control ring can all the limit columns be pulled out uniformly, and the limitation of the sealing ring piece can be cancelled at one time, which is conducive to improving installation efficiency.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] like Figure 1-3 As shown, the anchor protection cover provided in this embodiment includes a protection cover body 1 and a limiting column 2.

[0028] The protective cover body 1 has an open bottom end and a sealing ring body 11 is provided at the edge of the open end. A ring groove 111 is provided on the bottom side of the sealing ring body 11. A sealing ring piece 12 is installed in the ring groove 111 for sliding up and down. The sealing ring piece 12 fits tightly with the inner wall of the ring groove 111. A sealing layer 121 is installed on the bottom side of the sealing ring piece 12. The sealing layer 121 can be an elastic rubber layer. A spring 13 is connected between the top side of the sealing ring piece 12 and the top wall of the ring groove 111. The spring 13 can provide a Elastic force is provided to push the sealing ring sheet 12 out of the bottom of the ring groove 111, so that the sealing layer 121 can be in close contact with the surface of the anchor when the bottom of the protective cover body 1 is in contact with the surface of the anchor. A plurality of insertion holes 14 are evenly distributed on the outer circumference of the sealing ring body 11, and a mounting ring body 15 is provided on the outer periphery of the bottom side of the sealing ring body 11. A plurality of bolt holes 151 are provided on the mounting ring body 15. The bolt holes 151 are aligned with the bolt holes at the connection of the anchor, and the protective cover body and the anchor can be connected by screwing in the bolts.

[0029] A limiting post 2 is slidably inserted into each insertion hole 14 . By pushing the sealing ring 12 into the ring groove 111 , when the limiting post 2 is inserted into the insertion hole 14 , the sealing ring 12 can be pressed against its upper side and the spring 13 can be compressed.

[0030] Before installing the protective cover body 1 on the anchor, first push the sealing ring piece 12 into the annular groove 111, and insert each limiting column 2 into the insertion hole 14 to press the sealing ring piece 12 into the annular groove 111 to prevent the sealing ring piece 12 from being pushed out by the spring 13. After the mounting ring body 15 is connected and fixed to the installation position of the anchor by bolts, each limiting column 2 is pulled outward to make its inner end away from the annular groove 111, thereby canceling the limitation of the sealing ring piece 12. The sealing ring piece 12 will be pushed toward the surface of the anchor under the elastic force of the spring 13, so that the sealing layer 121 fully fits the surface of the anchor, so that the connection between the protective cover and the anchor is sealed and in contact, which is conducive to maintaining the sealing inside the protective cover and improving the protection effect of the inclined cable anchor.

[0031] The utility model presses the sealing ring piece 12 into the ring groove 111 through the limiting column 2, which can prevent the sealing ring piece 12 from being pushed apart by the spring 13 during the bolt connection of the mounting ring body 15 and the anchor, thereby reducing the difficulty of installing the protective cover and facilitating installation.

[0032] Preferably, the protective cover body 1 can be made of a transparent material so that staff can view the internal situation of the protective cover from the outside.

[0033] Preferably, an inner wall of the annular groove 111 away from each insertion hole 14 is provided with an end groove 112 corresponding to each insertion hole 14, and the inner end of the limiting column 2 can be inserted into the corresponding end groove 112 through the insertion hole 14, so that the rod surface of the limiting column 2 is evenly pushed by the sealing ring sheet 12, preventing the inner end of the limiting column 2 from being bent.

[0034] Furthermore, a sealing rubber ring 21 is provided around the limiting column 2. When the limiting column 2 is pulled outward, the sealing rubber ring 21 can fill the gap between the insertion hole 14 and the limiting column 2, thereby improving the sealing effect.

[0035] Since it is time-consuming to pull out each limiting column 2 one by one, in order to improve the installation efficiency of the protective cover, in one embodiment, the outer end of each limiting column 2 is respectively provided with an abutment block 22, and the outer side of the sealing ring body 11 is coaxially rotatably installed with a control ring 16, and the outer wall of the control ring 16 is evenly distributed with a plurality of abutment teeth 161, and the number of abutment teeth 161 corresponds to the limiting column 2. One side of the rotation direction of the abutment teeth 161 is smoothly connected with the outer wall of the control ring 16, and the other side is tilted outward and arched, and a limiting protrusion 162 is provided on the edge of the side.

[0036] During specific use, by rotating the control ring 16, the abutment blocks 22 of each limiting column 2 can be pushed outward by the corresponding pushing teeth 161, and the abutment blocks 22 will be pulled outward along the inclined slope of the pushing teeth 161, thereby pulling the limiting column 2 outward. When the abutment blocks 22 move to the highest point of the outward arch of the pushing teeth 161, they will abut and limit with the limiting protrusion 162. It is only necessary to rotate the control ring 16 to pull out all the limiting columns 2 at the same time, and cancel the limitation of the sealing ring sheet 12 at one time, which is conducive to improving installation efficiency.

[0037] Preferably, a handle 163 is provided on the outer side of the control ring 16 to facilitate the rotation of the control ring 16 .

[0038] Furthermore, the outer wall of the control ring 16 is provided with a sleeve 164, and a positioning column 165 is slidably inserted into the sleeve 164. A positioning hole 152 for inserting the positioning column 165 is opened on the mounting ring body 15, and when the positioning column 165 is inserted into the positioning hole 152, each abutment block 22 will be pushed outward along the inclined slope of the abutment tooth 161 to make the inner end of the limit column 2 move out of the ring groove 111, so that the control ring 16 can be fixed after the control ring 16 is rotated to release the limit on the sealing ring sheet 12, thereby preventing the control ring 16 from rotating uncontrollably.
