Description

Technical Field

[0001] This utility model relates to the technical field of underground engineering anchor cable construction equipment, and in particular to an isolation frame device for anchor cable construction. Background Technology

[0002] Anchor cable installation isolation frames are structures used to fix and separate steel strands during anchor cable construction. They ensure the steel strands are correctly positioned in the borehole, centered, guaranteeing uniform stress on the anchor cable and preventing localized stress concentration caused by strand misalignment, which could affect the anchoring effect and overall load-bearing capacity. Simultaneously, the isolation frame creates a uniform distribution of the steel strands within the hole, increasing the contact area between the strands and the borehole wall, and enhancing the friction and adhesion between the anchor cable and the surrounding soil and rock, thereby improving the anchoring force and making the anchor cable more secure. However, current isolation frames require binding each steel strand passing through the borehole with zinc-free lead wire on both sides of the isolation frame to prevent movement during construction. This can easily lead to inconsistent binding positions of the steel strands in different holes, resulting in ineffective fixing and potential twisting within the hole, causing uneven stress on the steel strands.

[0003] Therefore, it is necessary to provide a new isolation frame device for anchor cable construction to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an isolation frame device for anchor cable construction.

[0005] The anchor cable construction isolation frame device provided by this utility model includes an isolation plate, on which multiple pipe holes and several stranded wire holes are arranged in a ring around the multiple pipe holes.

[0006] Each of the stranded wire holes has an arc-shaped spherical cavity on its sidewall, and a guide groove is provided above the arc-shaped spherical cavity;

[0007] The isolation disk is equipped with a rotating ring that is rotatably connected, and the rotating ring is connected to multiple sets of abutment components that are distributed in a ring and respectively set in each arc-shaped spherical cavity;

[0008] The abutting assembly includes a steel ball and an arc-shaped spring. The arc-shaped spring is disposed inside an arc-shaped spherical cavity, and one end of the arc-shaped spring is fixedly connected to the inner wall of the arc-shaped spherical cavity. The other end of the arc-shaped spring extends into the stranded wire hole and is fixedly installed with a steel ball.

[0009] Preferably, the rotating ring has a T-shaped cross-section, and the insertion end of the rotating ring is inserted into the T-shaped groove of the isolation plate and rotatably connected to the T-shaped groove. Multiple L-shaped connecting rods are fixedly installed on the rotating ring, and the vertical ends of the L-shaped connecting rods are fixedly connected to the corresponding steel balls.

[0010] Preferably, the rotating ring has a mounting cavity, and a locking component for locking the rotating ring in the position of the isolation disc is installed in the mounting cavity.

[0011] Preferably, the locking assembly includes an insertion post inserted into the mounting cavity, and a sliding rod coaxially mounted on the top of the insertion post. The sliding rod extends out of the top of the mounting cavity and is fixedly mounted with a pull rod, and a strong spring is sleeved on the sliding rod.

[0012] Preferably, one end of the strong spring is fixedly connected to the inner top wall of the mounting cavity, and the other end of the strong spring is fixedly connected to the upper cylindrical surface of the insertion post.

[0013] Preferably, the isolation disc has a locking hole.

[0014] Preferably, the diameter of the strand hole is larger than the diameter of the steel strand.

[0015] Compared with related technologies, the anchor cable construction isolation frame device provided by this utility model has the following beneficial effects:

[0016] In this invention, after the steel strand passes through the strand hole, the upper pull rod drives the insertion post to slide out of the locking hole. At this time, the rotating ring rotates under the action of the arc spring force, and the steel ball sliding along the outside of the arc-shaped spherical cavity abuts against the part of the steel strand that has passed through the strand hole, making the steel strand more firmly connected to the isolation plate. This also reduces the hidden danger of fatigue failure of the steel strand due to local stress concentration after long-term use. Furthermore, through the cooperation of the rotating ring and multiple sets of abutting components, the steel strand in each strand hole can be positioned at once, avoiding the problem of inconsistent binding positions of the steel strands when using zinc-free lead wire to bind each steel strand later.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides an isolation frame device for anchor cable construction. The isolation frame device includes an isolation plate 1, an abutment component 2, and a rotating ring 3. The isolation plate 1 has multiple pipe holes 1a and several stranded wire holes 1b arranged in a ring around the multiple pipe holes 1a. The pipe holes 1a are used to pass through the grout inlet / outlet pipes, and the stranded wire holes 1b are used to pass through the steel strands. The diameter of the stranded wire holes 1b is larger than the diameter of the steel strands.

[0024] In the embodiments of this utility model, please refer to Figures 1 to 4 Each of the stranded wire holes 1b has an arc-shaped spherical cavity 1c on its sidewall, and a guide groove 1d is provided above the arc-shaped spherical cavity 1c. A rotating ring 3 is installed on the isolation disk 1 and is rotatably connected. Multiple sets of abutment components 2 are connected to the rotating ring 3 and are respectively arranged in each arc-shaped spherical cavity 1c. The abutment component 2 includes a steel ball 21 and an arc-shaped spring 22. The arc-shaped spring 22 is arranged in the arc-shaped spherical cavity 1c, and one end of the arc-shaped spring 22 is fixedly connected to the inner wall of the arc-shaped spherical cavity 1c. The other end of the arc-shaped spring 22 extends into the stranded wire hole 1b and is fixedly installed with a steel ball 21. Multiple L-shaped connecting rods 31 are fixedly installed on the rotating ring 3, and the vertical end of the L-shaped connecting rod 31 is fixedly connected to the corresponding steel ball 21.

[0025] The isolation disc 1 has a locking hole 1f, and the rotating ring 3 has a mounting cavity 3a. A locking component 4 for locking the rotating ring 3 in the position of the isolation disc 1 is installed in the mounting cavity 3a. The locking component 4 includes an insertion post 41, which is inserted into the mounting cavity 3a. A sliding rod 42 is fixedly installed on the top of the insertion post 41. The sliding rod 42 extends out of the top of the mounting cavity 3a and is fixedly installed with a pull rod 44. A strong spring 43 is sleeved on the sliding rod 42. One end of the strong spring 43 is fixedly connected to the inner top wall of the mounting cavity 3a, and the other end of the strong spring 43 is fixedly connected to the upper cylindrical surface of the insertion post 41.

[0026] It should be noted that: during the process of the steel strand passing through the stranding hole 1b, rotating the rotating ring 3 causes the L-shaped connecting rod 31 to rotate the steel ball 21 into the arc-shaped spherical cavity 1c. This causes the steel ball 21 to slide into the arc-shaped spherical cavity 1c and compress the arc-shaped spring 22. Simultaneously, the insertion post 41 slides along the upper surface of the isolation plate 1 until it aligns with the locking hole 1f. Under the elastic force of the strong spring 43, the insertion post 41 is driven to insert into the locking hole 1f, thus completing the storage of the steel ball 21. Because the steel ball 21 is stored in the arc-shaped spherical cavity 1c, the stranding hole 1b is fully exposed, allowing the steel strand to pass through it. After the steel strand passes through the stranding hole 1b, the upper... Pull rod 44 drives insertion post 41 to slide out of locking hole 1f. At this time, rotating ring 3 rotates under the action of arc spring 22, and steel ball 21 sliding out of arc spherical cavity 1c abuts against the steel strand passing through strand hole 1b, making the steel strand more firmly connected to isolation plate 1. It also reduces the hidden danger of fatigue failure of steel strand due to local stress concentration after long-term use. Furthermore, through the cooperation of rotating ring 3 and multiple sets of abutting components 2, the steel strand in each strand hole 1b can be positioned at one time, avoiding the problem of inconsistent binding positions of each steel strand when using zinc-free lead wire to bind each steel strand later.

[0027] Since the diameter of the strand hole 1b is larger than the diameter of the steel strand, the problem that the grout can only come out from the gap between the strand hole 1b and the steel strand during grouting is eliminated, which can easily cause the grout return to be blocked and lead to uneven local grout return in the channel.

[0028] In this embodiment, the rotating ring 3 has a T-shaped cross-section, and the insertion end of the rotating ring 3 is inserted into the T-shaped groove 1e of the isolation disk 1 and rotates in connection with the T-shaped groove 1e, which improves the stability of the rotating ring 3 rotating along the T-shaped groove 1e of the isolation disk 1.

[0029] The working principle of the anchor cable construction isolation frame device provided by this utility model is as described above.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
