Abstract
Description
Technical Field
[0001] This utility model relates to the field of anchor cable and anchorage technology, specifically to an anchor cable and anchorage for a mining hoist. Background Technology
[0002] Hoist anchors are key components used for fixing and hoisting equipment in mining and engineering machinery. Existing types and specifications can be divided into: (1) Circular anchors, common models such as YJM15-N or YJM13-N, which use a through-hole jack for tensioning and have excellent self-anchoring performance. They are suitable for scenarios requiring high load-bearing capacity, such as fixing the base of a hoist. (2) Flat anchors, models such as BJM15-N, are suitable for lateral prestressing requirements with limited space and can optimize stress distribution.
[0003] In practical use, the anchor cable of the hoist, as disclosed in the prior art (announcement number: CN217712631U), is a spherical anchor cable for mining. However, the installation structure of the anchor ring and the wedge needs further improvement to achieve a stable installation. During the hoisting process of the steel strand, the wedge cannot be positioned and sleeved inside the anchor ring, causing the wedge to easily move inside the sleeve hole of the anchor ring. This results in significant wear between the anchor ring and the wedge, as well as between the wedge and the steel strand, affecting the safe hoisting operation.
[0004] Therefore, there is a need to provide a mine hoist anchor cable anchor. Utility Model Content
[0005] In view of the problems existing in the prior art, this utility model provides a mine hoist anchor cable anchor, which aims to improve and solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mine hoist anchor cable anchor, comprising an anchor liner, an anchor ring, a wedge, and a spiral reinforcement. The anchor liner has a central and circumferential opening as a first sleeve hole. The anchor ring is embedded in the bottom of the anchor liner. The anchor ring also has a central and circumferential opening as a second sleeve hole. The first and second sleeve holes are correspondingly arranged and coaxially. A symmetrical slot is formed at the bottom of the second sleeve hole. The wedge is closed and clamped around the outside of the steel strand and fitted inside the second sleeve hole. The top of the wedge abuts against the bottom of the first sleeve hole. The bottom of the wedge is set as a retaining edge, which is engaged with the bottom of the second sleeve hole. One side of the retaining edge that contacts each other is set as a locking block. After the wedge is closed, the two locking blocks are joined together and inserted into the slot. The upper part of the anchor liner is set as a spiral reinforcement. The clamped steel strand passes sequentially through the second sleeve hole, the first sleeve hole, and through the central part of the spiral reinforcement, forming an anchor for the hoisting steel strand.
[0007] Preferably, after the clamping pieces are closed, one end of the side guard is symmetrically provided with an insertion slot, and one end of the side guard is symmetrically provided with an insertion block. After the clamping pieces are closed, the insertion block is inserted into the inside of the insertion slot, and then a locking block is inserted into the inside of the locking slot to securely connect and fix the insertion block to the insertion slot.
[0008] Preferably, the clamping pieces after being enclosed are arranged in a conical or cylindrical structure.
[0009] Preferably, the second sleeve hole is configured to match the shape of the clamping piece after it is closed, and the second sleeve hole is configured as a conical through hole structure.
[0010] Preferably, the inner diameter of the clamping piece after being enclosed is equal to the inner diameter of the sleeve hole.
[0011] In summary, this utility model provides a mine hoist anchor cable anchor. This utility model patent adopts a method in which the clamping piece is sleeved inside the sleeve hole after being enclosed, and the first locking block is locked into the first locking slot, forming a movable positioning and installation of the clamping piece in the circumferential and upward directions. This ensures that the clamping piece is positioned and installed inside the sleeve hole, avoids the clamping piece moving on the anchor ring, reduces the wear between the clamping piece and the anchor ring, and avoids the safety problem of the steel strand shaking during the hoisting process.
[0012] After the clamping piece is fitted into the second sleeve hole, it is engaged with the first slot by the first clamping block, further securing the insertion block and the slot. This improves the positioning of the clamping piece on the anchor ring, reduces wear on the clamping piece, anchor ring, and steel strand during the lifting process, and achieves the technical effect of safe lifting. By using the clamping piece that is enclosed and fitted into the second sleeve hole, the anchoring force of the steel strand is increased, improving the safe use of the steel strand during the lifting process and solving the wear problem.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figures 1 to 4 As shown:
[0020] This utility model relates to a mine hoist anchor cable. To address the issue of positioning the clamping piece 3 on the anchor ring 2, preventing the clamping piece 3 from moving inside the anchor ring 2 and reducing wear on the anchor ring 2, and to ensure stable lifting of the steel strand 11 during the hoisting process, avoiding vibration and safety issues, the specific solution adopted in this patent includes an anchor liner plate 1, an anchor ring 2, clamping pieces 3, and spiral reinforcement 4. The anchor liner plate 1 has a first-hole 5 in its center and circumference. The anchor ring 2 is embedded in the bottom of the anchor liner plate 1. The anchor ring 2 also has a second-hole 6 in its center and circumference. The first-hole 5 and the second-hole 6 are correspondingly arranged and coaxially aligned. The second-hole 6... A symmetrical bayonet opening 7 is made at the bottom. The clamping piece 3 is closed and held on the outside of the steel strand 11 and fitted inside the sleeve hole 6. The top of the clamping piece 3 is installed in contact with the bottom of the sleeve hole 5. The bottom of the clamping piece 3 is set as a retaining edge 12. The retaining edge 12 is installed in contact with the bottom of the sleeve hole 6. The side of the retaining edge 12 that is in contact with each other is set as a locking block 13. After the clamping piece 3 is closed, the two locking blocks 13 are inserted into the inside of the bayonet opening 7. The upper part of the anchor plate 1 is set as a spiral rib 4. The clamped steel strand 11 passes through the sleeve hole 6, the sleeve hole 5 and through the middle of the spiral rib 4 in sequence to form an anchor for the lifting steel strand 11.
[0021] The specific operating principle is as follows: The steel strand 11 passes through the second sleeve hole 6, the first sleeve hole 5, and through the middle of the spiral reinforcement 4 in sequence. The steel strand 11 located at the bottom of the anchor ring 2 is clamped and installed with a clamping plate 3. The clamping plate 3 connects the steel strand 11 and is sleeved inside the second sleeve hole 6. The bottom of the second sleeve hole 6 is symmetrically provided with a locking slot 7. The bottom of the clamping plate 3 is set as a retaining edge 12. The side of the retaining edge 12 that contacts each other is set as a locking block 13. After the clamping plate 3 is sleeved inside the second sleeve hole 6, the locking block 13 is locked into the locking slot 7, forming a movable positioning installation of the clamping plate 3 in the circumferential and upward directions. This ensures that the clamping plate 3 is positioned and installed inside the second sleeve hole 6, avoids the clamping plate 3 moving on the anchor ring 2, reduces the wear between the clamping plate 3 and the anchor ring 2, and avoids the safety problem of the steel strand 11 shaking during the lifting process.
[0022] In at least one embodiment, after the clamping piece 3 is closed, a slot 14 is symmetrically opened on one end of the side guard 12, and a plug block 15 is symmetrically provided on the other end of the side guard 12 after the clamping piece 3 is closed. After the clamping piece 3 is closed, the plug block 15 is inserted into the inside of the slot 14, and then inserted into the inside of the slot 7 by the locking block 13, so as to securely connect and fix the plug block 15 and the slot 14.
[0023] Specifically, to further ensure the clamping piece 3 is fixedly installed on the anchor ring 2 after being enclosed, a symmetrical insertion port 14 is opened at the end of one side of the retaining edge 12, and a symmetrical insertion block 15 is set at the end of the retaining edge 12 on the other side. After the clamping piece 3 is enclosed, the insertion block 15 is inserted into the insertion port 14. After the clamping piece 3 is sleeved into the sleeve hole 6, it is locked into the slot 7 by the locking block 13. This further fixes the insertion block 15 and the insertion port 14, improves the positioning and installation of the clamping piece 3 on the anchor ring 2, reduces the wear of the clamping piece 3, the anchor ring 2 and the steel strand 11 during the lifting process, and achieves the technical effect of safe lifting and use.
[0024] In at least one embodiment, to further enhance the anchoring effect, the enclosed clamp 3 is arranged in a conical column structure; the sleeve hole 6 is matched with the shape of the enclosed clamp 3, and the sleeve hole 6 is arranged in a conical column through hole structure; by using the enclosed clamp 3 and the sleeve hole 6 to fit together and be installed, the anchoring force of the steel strand 11 is enhanced, the safe use of the steel strand 11 during the lifting process is improved, and the wear problem is solved.
[0025] In at least one embodiment, in order to achieve a stable anchoring force, the inner diameter of the clamping piece 3 after being enclosed is equal to the inner diameter of the sleeve hole 5. This serves to further limit the clamping piece 3 by the anchor liner plate 1 during the lifting process, thereby improving the clamping and anchoring effect of the clamping piece 3 on the steel strand 11.
[0026] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
