Description
Technical Field
[0001] This utility model belongs to the field of multi-anchor pile technology, specifically relating to a multi-anchor pile tension adjustment device. Background Technology
[0002] Anchor piles, as structural components resisting lateral tensile forces, are widely used in various scenarios such as ship mooring and securing, temporary fixing during disaster relief towing operations, and temporary towing protection for construction equipment. When the lateral tensile force to be resisted is large, steel wire ropes are often required for the anchor ropes, and the pile hole location must be selected in areas of dense rock or soil. When conditions are limited and the pile hole can only be drilled in areas of soft soil, and conventional single anchor piles cannot serve as reliable anchor points, multi-anchor piles, such as double or triple anchor pile schemes, can be used as reinforcement measures. The double anchor pile scheme involves the anchor piles arranged in a straight line, while the triple anchor pile scheme involves either a straight line or an inverted triangular arrangement. In both double and triple anchor pile schemes, the rear pile tows the front pile via a pull rope, and the stressed anchor rope 5 is directly attached to the front pile. Figure 1 As shown, taking the inverted triangle arrangement of three anchor piles as an example, the working mechanism of the multi-anchor pile scheme is as follows: When the pile head tilts in the direction of force under the tension of the anchor rope, resulting in significant deformation, the tension rope attached to the rear pile is tightened by the pressure of the front pile head, generating stress. This causes the rear pile to share the force with the front pile, enhancing the reliability of the anchor pile. According to the working mechanism of the multi-anchor pile, the tension of the tension rope has a significant impact on the reliability of the multi-anchor pile. Insufficient tension of the tension rope may even lead to the failure of the multi-anchor pile.
[0003] Multi-unit anchor piles are often used in scenarios with high stress and as temporary fixing measures. Their anchor ropes and tension ropes are generally made of steel wire rope. According to current common practice, when setting up the tension ropes, the length of the tension rope and the rope binding method are usually calculated in advance based on the spacing between the multi-unit anchor piles. After the anchor piles are in place, the tension rope is then looped between them. Because the tension rope is made of steel wire rope, it has high strength. If the pre-set length is too short, it will not be able to be smoothly looped between the anchor piles; if the pre-set length is too long, the multi-unit anchor piles cannot be linked to bear the force in time, leading to the failure of the multi-unit anchor piles. Therefore, to ensure the effectiveness of the multi-unit anchor piles, the tension of the tension rope should be adjusted promptly after it is looped.
[0004] Under current technological conditions, adjusting the tension of the traction rope requires unfastening each of the clamps on the wire rope, tightening it, and then retightening the clamps. This process is cumbersome. Since the wire rope tensioning is done manually without tools, the final tension quality cannot be guaranteed. Furthermore, the entire tensioning process requires at least two people: one to tighten the wire rope and the other to tighten the clamps, resulting in high operating costs. As a temporary fixation measure, the frequent unfastening and tightening of the wire rope clamps severely shortens the lifespan of both the wire rope and the clamps. While theoretically it's possible to tighten the wire rope using chain hoists or similar equipment, this significantly increases the difficulty and complexity of the construction operation, contradicting its intended purpose as a temporary fixation measure.

[0027] like Figure 2As shown in Figure 5, this utility model provides a multi-link anchor pile tension adjustment device, including a left fixed frame 6 and a right fixed frame 7 that are fixedly connected to each other.

A positioning adjustment nut 10 is screwed onto the screw sections of the two hook bolts 9, and the positioning adjustment nut 10 is located on the outside of the left fixing frame 6 and the right fixing frame 7.
[0039] The working principle of this utility model is as follows:
[0040] Anchor pipe 17 is inserted into anchor pipe sleeve 8, and left fixing frame 6 and right fixing frame 7 are fixed to anchor pipe 17 through anchor pipe sleeve 8. A rope loop is formed at the end of pull rope 3 using wire rope clamp 4. The rope loop is placed on the outside of anchor pipe 17 and passes through the inside of left fixing frame 6 and right fixing frame 7. The pull rope 3 located inside left fixing frame 6 and right fixing frame 7 is hooked to the hook sections of two hook bolts 9. At this point, mutual traction between anchor pipe 17 and pull rope 3 is achieved. When the tension of pull rope 3 needs to be adjusted, the positioning adjusting nuts 10 on both sides are rotated to allow the two hook bolts 9 to move left and right. The anti-torsion mechanism and displacement groove 14 prevent the hook bolts 9 from twisting during left and right movement. When the two hook bolts 9 approach each other, pull rope 3 is loosened; when the two hook bolts 9 move away from each other, pull rope 3 is tightened.
[0041] The specific operation method of this utility model is as follows, taking the inverted triangular arrangement of three anchor piles as an example:
[0042] (1) The rope loops at both ends of the pull rope 3, which has a pre-set total length and rope loop length, are respectively put on the outside of the two rear piles 2, and the middle part of the pull rope 3 is wrapped around the front pile 1.
[0043] (2) Pass the left fixing frame 6 and the right fixing frame 7 through the pull rope 3 respectively, so that the pull rope 3 inside the left fixing frame 6 and the right fixing frame 7 are respectively hooked on the hook section of the head of the two hook bolts 9;
[0044] (3) Fasten the left fixing bracket 6 and the right fixing bracket 7 together, and cover the anti-detachment clip 16;
[0045] (4) Put the anchor pipe sleeve 8 on the anchor pipe 17, so that the bolt through hole on the anchor pipe sleeve 8 faces the left fixing frame 6 and the right fixing frame 7.
[0046] (5) Secure the left fixing frame 6, the right fixing frame 7, and the anchor pipe sleeve 8 together with the fastening bolts 15 and fastening nuts;
[0047] (6) Use a wrench to turn the positioning adjustment nuts 10 on the left and right sides respectively, so that the hook bolt 9 moves left and right, adjust the opening degree of the pull rope 3 set, and make the pull rope 3 reach the ideal tension state.
[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
