Description

Technical Field

[0001] The invention belongs to the field of cable lowering devices, and in particular relates to an auxiliary cable lowering device in anchor cable construction. Background Art

[0002] Cable anchor construction is a crucial civil engineering technology, which is widely used in infrastructure construction such as bridges, tunnels, subways and high-rise buildings. Its main function is to enhance the stability and bearing capacity of the structure through the prestressing effect of the cable anchor. However, in actual construction, due to the layout position of the cable anchor, tension control and construction accuracy requirements, construction workers often face the challenge of how to ensure the stable positioning of the lower cable (i.e. the lower end of the cable anchor).

[0003] In traditional anchor cable construction methods, construction workers usually rely on manual operation and simple fixing devices to complete the positioning and tension adjustment of anchor cables. It is common to adjust the position of anchor cables by manual tools, and then fix them in the predetermined position with mechanical devices (such as bolts, clamps, etc.). Although these traditional methods can meet basic requirements in some cases, their application in many modern projects has exposed some significant limitations.

[0004] First, low positioning accuracy is a key issue. Due to reliance on manual operation, construction workers often need to visually observe and estimate the exact position of the anchor cable, making it difficult to make high-precision adjustments. Especially in complex projects such as large bridges and tunnels, the difficulty of precise positioning is further increased due to environmental restrictions and changes in construction conditions. Even with the use of some basic mechanical tools, errors are still inevitable, which may cause the anchor cable position to deviate from the design requirements or even shift, which in serious cases will affect the stability and safety of the structure.

[0005] Human error is also a major shortcoming of traditional methods. Since a large number of manual operations are involved in the construction process, whether in the positioning, adjustment or locking of the anchor cable, it is easy to be affected by factors such as the operator's experience, skills and attention, leading to errors. Especially in harsh construction environments, manual operations are more susceptible to interference from external factors (such as weather, light, line of sight, etc.), increasing the uncertainty and risk of operations.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0036] In this embodiment, a guide cylinder 9 is fixedly connected to the top of the base 1, a push rod 10 is connected to the top of the rotating plate 3, a guide groove is provided on the circumferential side of the inner wall of the guide cylinder 9, and the push rod 10 slides inside the guide groove, and the guide groove is an arc groove 11 on the side close to the bottom plate, and a straight groove extends above the arc groove 11. By providing the guide grooves of the arc groove 11 and the straight groove, combined with the cooperative work of the push rod 10 and the guide cylinder 9, the device can realize the rotation of the rotating plate 3 during the sliding of the combined plate up and down. This design allows the device to achieve the rotation effect of the anchor cable in the drill hole by utilizing the rotation function of the rotating plate 3 after clamping the anchor cable, effectively improving the coordination between the anchor cable and the grouting and the construction efficiency.

The roller 20 design between the slider 14 and the clamping block 19 further improves the smoothness of clamping, reduces friction, makes the clamping and locking process more stable, and avoids the phenomenon of loose clamping or position deviation.
