Description

Technical Field

[0001] This utility model relates to the field of anchor cable isolation frame technology, and in particular to a detachable anchor cable isolation frame device. Background Technology

[0002] Prestressed anchor cables are prestressed components consisting of several strands of steel wire or strand arranged in a certain pattern to anchor unstable rock masses. They are made by drilling through weak rock layers or sliding surfaces, anchoring one end to hard rock layers (called the inner anchor head), and tensioning the other free end (called the outer anchor head).

[0003] Anchor cable bundling requirements:

[0004] 1) Stack the cut steel strands and inlet and return slurry pipes on the work platform, and number the different inlet and return slurry pipes and steel strands at the inlet section and distinguish them with different colors;

[0005] 2) At intervals in the anchoring section, the steel strands are fixed with isolation frames and tight rings to make them shaped like a date pit;

[0006] 3) To ensure the anchor cable is centered, it is tied with wire at regular intervals along the length of the anchor cable. When tying, ensure that the steel strands are parallel to the grouting pipe and that there is no crossing.

[0007] 4) Put a guide cap on the end of the anchor cable.

[0008] The function of the isolation frame is:

[0009] 1) Expand the steel strands to form a lotus root-like structure, thereby increasing the anchoring force of the anchor cable;

[0010] 2) Straighten the steel strands so that they are not tangled and that the force is evenly and fully distributed.

[0011] The isolation frames currently used, such as Figure 7 As shown, due to frequent overlapping operations on site, and collisions and crushing by large machinery during handling, the isolation frame is easily damaged. Since the damaged isolation frame has other isolation frames and cable ring devices at both ends, and the complete isolation frame structure cannot be disassembled, it is impossible to replace the damaged equipment. If replacement is required, the isolation frame, cable rings, and binding wires must be removed up to the end to complete the replacement, greatly increasing the workload. This application is proposed to address these shortcomings. Utility Model Content

[0012] The purpose of this invention is to provide a detachable anchor cable isolation frame device, which solves the problems of difficulty in replacing the isolation frame after installation and the large amount of work required for replacement.

[0013] To address the aforementioned problems, this utility model provides a detachable anchor cable isolation frame device, comprising an outer ring and an inner disc. The outer ring includes two sets of semi-outer rings and a rotating structure connecting the two sets of semi-outer rings. The semi-outer rings can be rotated open and are provided with a locking structure. The locking structure is used to lock the two sets of semi-outer rings together, thus giving the outer ring two states: a merged state and an unfolded state. During disassembly, it is only necessary to adjust it to the unfolded state for disassembly, without disassembling the surrounding isolation frame. The semi-outer rings are provided with outer ring grooves, and the inner disc is provided with inner disc grooves and tube fixing holes. After the inner disc and the outer ring are combined, the inner disc grooves and the outer ring grooves form a slot for fixing the anchor cable.

[0014] According to one embodiment of the present invention, the inner disk includes two sets of half inner disks and a rotating structure two connecting the two sets of half inner disks.

[0015] According to one embodiment of the present invention, the outer ring and the inner disc are fitted together by a flexible tenon and mortise structure.

[0016] Optionally, the tube fixing holes are provided in multiple sets, that is, multiple independent holes are provided.

[0017] Optionally, the tube fixing hole is a plum blossom-shaped through hole.

[0018] According to one embodiment of the present invention, the locking structure includes a snap-fit ​​structure.

[0019] According to one embodiment of the present invention, the locking structure includes an ear plate and a bolt assembly connected to the outer half ring.

[0020] Optionally, the inner half of the disc is provided with a locking structure.

[0021] The beneficial effects of this utility model are that by setting the outer ring and inner plate as a rotatable and unfoldable structure, when the isolation frame is damaged due to collision or other reasons after installation, it can be replaced simply by unfolding and disassembling the damaged outer ring and inner plate without disassembling the surrounding isolation frame, thereby greatly improving the replacement efficiency. Furthermore, when only the outer ring or inner plate is damaged, the outer ring or inner plate can be replaced separately, reducing costs. Attached Figure Description

[0030] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0031] Example 1:

[0032] A detachable anchor cable isolation frame device, such as Figure 1 It includes the outer ring 1 and the inner ring 2.

[0033] like Figure 2 The outer ring 1 includes two sets of semi-outer rings 11 and a rotating structure 12 connecting the two sets of semi-outer rings 11. The rotating structure 12 can be a hinge or a hinge support or other structure that can realize the rotatable connection between the semi-outer rings 11. The semi-outer rings 11 can be rotatably opened. The semi-outer rings 11 are provided with a locking structure. The locking structure is used to lock the two sets of semi-outer rings 11 when they are combined. The semi-outer rings 11 are provided with an outer ring groove 13.

[0034] The outer ring 1 has two states: a merged state and an unfolded state. The merged state is when the half outer ring 11 merges into a circular shape, and the unfolded state is when the half outer ring 11 rotates and unfolds. During disassembly, it can be disassembled simply by adjusting it to the unfolded state, without having to disassemble the surrounding isolation frame, thus greatly improving the replacement efficiency.

[0035] Since the outer ring 1 is located outside the isolation frame and is easily damaged by collisions, in this embodiment, only the outer ring 1 is set as a structure that can be unfolded and disassembled.

[0036] The locking structure can be selected from two types, one of which is as follows: Figure 2 The locking structure includes a snap-fit ​​structure 14 or a tenon-and-mortise structure. The snap-fit ​​structure 14 includes a male and a female snap respectively disposed on the two outer ring halves 11, which engage to achieve a fixed connection between the two outer ring halves 11; another structure is as follows Figure 3 It includes a lug 15 and a bolt assembly 16 connected to the outer half ring 11. The lug 15 can be set on the outer circular surface or on the end face and is fixed by the bolt assembly 16.

[0037] like Figure 4 The inner plate 2 is provided with an inner plate groove 21 and a tube fixing hole 22. After the inner plate 2 is combined with the outer ring 1, the inner plate groove 21 and the outer ring groove 13 form a slot 3 for fixing the anchor cable.

[0038] In this embodiment, multiple sets of pipe fixing holes 22 are provided for fixing pipe fittings such as grouting pipes, injection pipes, and ventilation pipes.

[0039] Example 2:

[0040] Unlike in Embodiment 1, in this embodiment, the inner plate 2 is also configured as a rotatable and unfoldable structure, which facilitates the overall replacement of the isolation frame.

[0041] Specifically, such as Figure 5 The inner disk 2 includes two sets of semi-inner disks 23 and a rotating structure 24 connecting the two sets of semi-inner disks 23. The rotating structure 24 can be a hinge or other structure that can achieve a rotating connection between the semi-inner disks 23.

[0042] In this embodiment, the tube fixing hole 22 is a plum blossom-shaped through hole. When the semi-inner plate 23 is unfolded, the plum blossom-shaped through hole opens accordingly, which makes the installation of the inner plate 2 more convenient and eliminates the need for perforation.

[0043] Optionally, a locking structure is provided on the semi-inner disc 23, and the locking structure can be one of the two structures in Embodiment 1.

[0044] Usage steps:

[0045] Open the half inner plate 23 of the inner plate 2, place the grouting pipe, grouting pipe and ventilation pipe and other pipe fittings into the pipe fixing hole 22, fix the pipe fittings with the pipe fixing hole 22, and connect the two half inner plates 23 using the locking structure.

[0046] The anchor cable is placed in the inner plate groove 21 to distribute and fix the anchor cable evenly.

[0047] The outer ring 1 wraps around the inner plate 2, and the groove 13 of the outer ring and the groove 21 of the inner plate are used to form a slot 3 for fixing the anchor cable. Then, the half outer ring 11 is connected by a locking structure.

[0048] The above method allows for the replacement of damaged isolation frames without removing other isolation frames and overhead wire rings.

[0049] Example 3:

[0050] Based on embodiment 1 or 2, in this embodiment, as Figure 6 The outer ring 1 and the inner plate 2 are connected by a flexible tenon and mortise structure. The outer circle of the inner plate 2 is provided with several flexible protrusions 25, which can be made of rubber or plastic. The flexible protrusions 25 are located on both sides of the groove 21 of each inner plate. The inner wall of the outer ring 1 is provided with grooves that match the flexible protrusions 25. After the outer ring 1 and the inner plate 2 are nested and installed, the flexible protrusions 25 are located in the grooves, which can play a role in positioning the two and preventing the outer ring 1 and the inner plate 2 from rotating relative to each other.

[0051] In other embodiments, an ear plate with bolt holes may be provided on the end faces of the outer ring 1 and the inner plate 2. The ear plate is provided with flexible protrusions 25 and grooves, and the inner and outer rings are connected by bolts.

[0052] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
