Description

Technical Field

[0001] The utility model relates to the technical field of anchor cables, in particular to an anchor cable recovery device. Background Art

[0002] Anchor cables are a crucial piece of equipment used in civil engineering and building construction, primarily for reinforcing and stabilizing structures. Typically made from high-strength steel wire rope or rebar, they effectively resist both tensile and shear forces and are widely used in projects such as bridges, tunnels, subways, slope support, and high-rise buildings.

[0003] Common anchor cables are not recyclable, and the non-recyclable anchor cables contain a large number of steel strands used temporarily for foundation pit support, which are permanently left underground, causing serious underground pollution, wantonly encroaching on space outside the red line, and resulting in material waste;

[0004] Therefore, a variety of recyclable anchor devices have appeared on the market, such as a recyclable anchor disclosed in Chinese Patent Publication No. CN220246908U and a recyclable anchor disclosed in Chinese Patent Authorization Announcement No. CN114319347B.

[0005] In view of this, the present invention proposes a recyclable anchor cable structure which is different from the above structure and can also solve the problem of the anchor cable being non-recyclable. Utility Model Content

[0006] The purpose of the utility model is to provide an anchor cable recovery device, which has the advantages of convenient anchor cable recovery, resource saving and pollution reduction.

[0007] In order to achieve the above objectives, the solution of the present invention is:

[0008] An anchor cable recovery device comprises a bearing body, a bearing sleeve, a hard rubber ring, a connecting frame, an annular seat, a main cable and a recovery cable;

[0009] The bearing sleeve is arranged on the top of the bearing body;

[0010] The main body of the bearing sleeve is in the shape of a cylinder that passes through from top to bottom, and the top edge of the main body of the bearing sleeve forms an arc-shaped retaining ring that extends upward and contracts radially inward;

[0011] The hard rubber ring, the connecting frame and the annular seat are all accommodated in the bearing sleeve, and the lower ends of the main rope and the recovery rope are inserted into the bearing sleeve;

[0012] The outer diameter of the hard rubber ring is not larger than the inner diameter of the main body of the bearing sleeve, and not smaller than the inner diameter of the top through hole of the arc-shaped retaining ring;

[0013] The connecting frame is located below the hard rubber ring and includes a soft portion in the middle and a plurality of rigid portions radially connected to the outer periphery of the soft portion. The center of the soft portion is connected to the recovery cable, while the middle of each rigid portion is connected to the main cable. One end of each rigid portion away from the soft portion is connected to the bottom of the hard rubber ring.

[0014] The connecting frame is placed above the annular seat on the top of the carrier. One end of the rigid part of the connecting frame connected to the hard rubber ring is located on the outer periphery of the annular seat and forms a movable space between the connecting frame and the top surface of the carrier.

[0015] Furthermore, it also includes a connecting plate; the connecting plate is located in the annular middle part of the hard rubber ring, and the outer periphery of the connecting plate has a plurality of circumferentially spaced connecting blocks connected to the hard rubber ring, and the connecting plate is provided with a clearance hole for the main rope and the recovery rope to pass through.

[0016] Furthermore, the annular seat extends toward the arc-shaped retaining ring, and a plurality of grooves are recessed on the top of the annular seat for the rigid part to pass through; the number of the connecting blocks is the same as the number of the rigid parts, and they are also located in the grooves, and the connecting plate is located inside the annular seat.

[0017] Furthermore, the outer periphery of the soft portion is provided with four rigid portions which are evenly spaced apart in the circumferential direction.

[0018] Furthermore, the rigid part is connected to the bottom of the hard rubber ring through a connecting column.

[0019] Furthermore, the top outer edge of the hard rubber ring is provided with an arc chamfer.

[0020] After adopting the above technical solution, when the recyclable anchor cable is in use, the carrier serves as the anchoring section. During the use of the anchor cable, each main cable is fixed by tightening. During the tightening of the main cable, the bottom of the main cable is connected to the rigid part of the connecting frame, and each main cable is forced to move upward, and at the same time drives all the rigid parts of the connecting frame to move upward, and one end of each rigid part will act on the hard rubber ring, so that the lower surface of the hard rubber ring is subjected to an upward force. After the hard rubber ring is subjected to force as a whole, it will fit tightly against the arc-shaped retaining ring of the bearing sleeve and be limited by the arc-shaped retaining ring that is radially retracted at the upper end. That is, the hard rubber ring does not deform when each main cable moves upward, and the overall outer diameter of the hard rubber ring is always larger than the diameter of the through hole formed in the middle part of the upper end of the arc-shaped retaining ring of the bearing sleeve. The hard rubber ring will not be pulled out, and the main cable is in a tightened state.

[0021] When the anchor cable needs to be recovered, a pulling force is applied to the recovery cable. When the recovery cable is subjected to the pulling force, the soft part of the connecting frame fixedly connected to the bottom of the recovery cable is driven. The soft part is deformed by the pulling force, and the soft part moves upward, driving the inner ends of the connected rigid parts to move upward, so that the rigid parts of the connecting frame are tilted, that is, the outer connecting end of the rigid part and the hard rubber ring will move downward in the active space, thereby the lower surface of the hard rubber ring is subjected to downward pulling force, the hard rubber ring is deformed, and the overall outer diameter becomes smaller. When the outer diameter of the hard rubber ring is smaller than the diameter of the arc-shaped retaining ring through hole at the upper end of the bearing sleeve, the hard rubber ring will be pulled out of the interior of the bearing sleeve, so that the recovery cable and the main cable can be recovered, so that the recovery cable and the main cables are pulled out as a whole. During the recovery process, only the bearing body and the bearing sleeve are reserved, which greatly increases the recovery rate and avoids the problem of incomplete recovery.

DETAILED DESCRIPTION

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] like Figures 1 to 5 As shown, an anchor cable recovery device of this embodiment includes a bearing body 1, a bearing sleeve 2, a hard rubber ring 3, a connecting frame 4, an annular seat 5, a main cable 6 and a recovery cable 7.

[0030] The bearing sleeve 2 is provided on the top of the bearing body 1; the two can be welded and fixed into one.

[0031] The main body 21 of the bearing sleeve 2 is cylindrical and extends from top to bottom, and the top edge of the main body 21 of the bearing sleeve 2 forms an arcuate retaining ring 22 that extends upward and contracts radially inward; the arcuate retaining ring 22 can be integrally formed on the upper part of the main body 21 of the bearing sleeve 2.

[0032] The hard rubber ring 3 , the connecting frame 4 and the annular seat 5 are all accommodated in the bearing sleeve 2 , and the lower ends of the main rope 6 and the recovery rope 7 are passed through the bearing sleeve 2 .

[0033] The outer diameter of the hard rubber ring 3 is not larger than the inner diameter of the main body 21 of the bearing sleeve 2 , and is not smaller than the inner diameter of the top through hole 221 of the arc-shaped retaining ring 22 .

[0034] The connecting frame 4 is located below the hard rubber ring 3 and includes a soft portion 41 in the middle and several rigid portions 42 radially connected to the outer periphery of the soft portion 41. The center of the soft portion 41 is connected to the recovery cable 7, while the center of each rigid portion 42 is connected to the main cable 6. The end of each rigid portion 42 away from the soft portion 41 is connected to the bottom of the hard rubber ring 3.

[0035] The soft portion 41 may be a rubber component, and the rigid portion may be made of metal.

[0036] The connecting frame 4 is also placed above the annular seat 5 on the top of the carrier 1. One end of the rigid portion 42 connecting the connecting frame 4 to the hard rubber ring 3 is located on the periphery of the annular seat 5, and a movable space 8 is formed between the connecting frame 4 and the top surface of the carrier 1.

[0037] In this way, when the recyclable anchor cable is in use, the carrier body 1 serves as an anchoring section. During the use of the anchor cable, each main cable 6 is tightened and fixed. During the tightening of the main cable 6, the bottom of the main cable 6 is connected to the rigid part 42 of the connecting frame 4. Each main cable 6 is forced to move upward, and at the same time drives all the rigid parts 42 of the connecting frame 4 to move upward, and one end of each rigid part 42 will act on the hard rubber ring 3, so that the lower surface of the hard rubber ring 3 is subjected to an upward force. After the hard rubber ring 3 is subjected to force as a whole, it will tightly fit the arc-shaped retaining ring 22 of the carrier sleeve and be limited by the arc-shaped retaining ring 22 radially retracted at the upper end. That is, the hard rubber ring 3 does not deform when each main cable 6 moves upward, and the overall outer diameter of the hard rubber ring 3 is always larger than the diameter of the through hole 221 formed in the middle part of the upper end of the arc-shaped retaining ring 22 of the carrier sleeve. The hard rubber ring 3 will not be pulled out, and the main cable 6 is in a tightened state.

[0038] When it is necessary to recover the anchor cable, a pulling force is applied to the recovery cable 7. When the recovery cable 7 is subjected to the pulling force, the soft part 41 of the connecting frame 4 fixedly connected to the bottom of the recovery cable 7 is driven. The soft part 41 is deformed by the pulling force, and the soft part 41 moves upward to drive the inner ends of the connected rigid parts 42 to move upward, so that the rigid parts 42 of the connecting frame 4 are tilted, that is, the rigid part 42 and the outer connection end of the hard rubber ring 3 will move downward in the movable space 8. As a result, the lower surface of the hard rubber ring 3 is subjected to downward pulling force, and the hard rubber ring 3 is deformed, and the overall outer diameter becomes smaller. When the outer diameter of the hard rubber ring 3 is smaller than the diameter of the through hole 221 of the arc-shaped retaining ring 22 at the upper end of the bearing sleeve, the hard rubber ring 3 will be pulled out of the bearing sleeve 2, so that the recovery cable 7 and the main cables 6 can be recovered, so that the recovery cable 7 and the main cables 6 are pulled out as a whole. During the recovery process, only the carrier 1 and the bearing sleeve 2 are reserved, which greatly increases the recovery rate and avoids the problem of incomplete recovery.

[0039] In order to improve the integrity of each main cable 6 and the hard rubber ring 3, a connecting plate 9 is further provided in this embodiment.

[0040] The connecting plate 9 is located in the annular middle of the hard rubber ring 3, and has a plurality of circumferentially spaced connecting blocks 10 on the outer periphery thereof connected to the hard rubber ring 3, and a clearance hole 91 is provided on the connecting plate 9 for the main rope 6 and the recovery rope 7 to pass through.

[0041] In this embodiment, the connecting plate 9 can be made of metal, and the connecting block 10 can be a hard rubber component. The two ends of the connecting block 10 can be welded to the connecting plate 9 and the hard rubber ring 3 respectively to form a whole.

[0042] Therefore, when the main cable 6 moves upward, the hard rubber ring 3, the connecting plate 9 and the connecting block 10 can be driven to move upward as a whole; the aperture of the clearance hole 91 can be slightly larger than the outer diameter of the main cable 6, that is, it has both a clearance function and a certain limiting function. Each main cable 6 passes through the clearance hole 91 on the connecting plate 9, which can improve the overall stability of each main cable 6.

[0043] In this embodiment, the outer periphery of the flexible portion 41 is provided with four rigid portions 42 evenly spaced circumferentially. This allows the connecting frame 4 to form a "cross" shape. Accordingly, four main cables 6 are provided. These four main cables 6 are connected to the four rigid portions 42 to apply upward or downward force to the lower surface of the hard rubber ring 3, thereby driving the hard rubber ring 3 upward or deforming.

[0044] Of course, the number of the rigid parts 42 may be 3, 5, etc., and is not limited to this embodiment.

[0045] In this embodiment, the annular seat 5 is provided to elevate the connecting frame 4 so that the rigid portion 42 can tilt and move within the bearing sleeve 2. Furthermore, the annular seat 5 is extended toward the arc-shaped retaining ring 22, and a plurality of grooves 51 are formed on the top of the annular seat 5 for the rigid portion 42 to pass through. In this embodiment, there are four grooves 51, and the number of the connecting blocks 10 is the same as the number of the rigid portions 42, both of which are located in the grooves 51. Thus, the connecting plate 9 can be installed inside the annular seat 5, facilitating product assembly.

[0046] In this embodiment, the rigid portion 42 can also be connected to the bottom of the hard rubber ring 3 via a connecting column 421. The provision of the connecting column 421 can make it easier for the rigid portion 42 to drive the hard rubber ring to deform.

[0047] In this embodiment, the top outer edge of the hard rubber ring 3 may be provided with an arcuate chamfer 31. This allows the outer edge to abut against the lower surface of the arcuate retaining ring 22 when the main cable 6 is forced to move the hard rubber ring 3 upward, thereby enhancing the snug fit. Furthermore, when the recovery cable 7 is forced to deform and move the hard rubber ring 3 upward, the arcuate chamfer 31 facilitates the removal of the hard rubber ring 3 from the through-hole 221 of the bearing sleeve 2.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, equivalent changes and modifications that do not depart from the principles of the present invention should still fall within the scope of protection of the present invention.
