Description

Technical Field

[0001] This utility model belongs to the field of soil reinforcement technology, and in particular relates to an auxiliary cable-laying device for high slopes. Background Technology

[0002] Retaining walls are a common type of support structure in various engineering constructions, possessing numerous advantages such as simple structure, small footprint, convenient construction, and low cost. However, the anchor cable construction of ultra-high retaining walls involves high-altitude operations, making cable threading at height difficult. Generally, cranes are used for auxiliary cable threading, but this involves large machine shifts and limited operating space for workers, hindering rapid cable threading. Three major drawbacks exist: anchor cables may bend and deform during hoisting due to lack of protection; manual adjustment of anchor cables and cable holes at height is time-consuming and has a high deviation rate on steep slopes; and there is a risk of fall from height when manually unlocking anchor cables. Therefore, there is an urgent need for an auxiliary cable-laying device for high slopes that can solve these problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an auxiliary cable lowering device for high slopes, which is especially suitable for anchor cable construction of ultra-high retaining walls.

[0010] Furthermore, the support mechanism includes:

[0011] A fixing knob is located at the lower end of the semi-enclosed guide groove;

[0012] The connecting part is connected to the fixing button at its front end.

[0013] Furthermore, the connecting portion includes:

[0015] The docking component is connected to the other end of the telescopic component.

[0016] Furthermore, the locking adjustment element is a turnbuckle.

[0017] The advantages and positive effects of this utility model are as follows: Due to the adoption of the above technical solution, the semi-enclosed guide channel ensures that the anchor cable is protected throughout the process, avoiding bending damage; the combination of the hoisting interface and the support mechanism enables the overall device to be quickly hoisted and firmly fixed, reducing the time for high-altitude adjustment; the combination of the locking adjustment component and the end restraint device provides double protection against slippage of the anchor cable during transportation, significantly improving construction safety; the connection part realizes the modular design of the support mechanism, which is convenient for folding, storage, disassembly and maintenance, and extends the service life of the device; the telescopic component flexibly adjusts the height and inclination angle of the guide channel to adapt to slopes with different gradients.

[0023] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.

[0024] like Figures 1-2 As shown, this utility model provides a high slope auxiliary cable lowering device for use in conjunction with the operating platform 70 for anchor cable 60 construction, including:

[0025] A semi-enclosed guide channel 10 is used to place the anchor cable 60;

[0026] The semi-enclosed guide channel 10 has a U-shaped or C-shaped cross section, which is used to restrain the radial deformation of the anchor cable 60 when it is lifted during construction.

[0027] At least two hoisting interfaces 20 are provided at the upper end of the semi-enclosed guide channel 10;

[0028] At least two lifting interfaces 20 are symmetrically welded to the upper end face of the semi-enclosed guide channel 10, with the center distance being 1 / 3 to 1 / 2 of the length of the guide channel to ensure balance when lifted. The locking adjustment component 40 can be directly connected to the semi-enclosed guide channel 10 or connected to the lifting interface 20.

[0029] At least one support mechanism 30 is provided at the lower end of the semi-enclosed guide groove 10 for connecting and fixing the operating platform 70;

[0030] A locking adjustment element 40 is provided at one end of the semi-enclosed guide groove 10.

[0031] The other end of the locking adjustment member 40 is connected to the end restraint 50 and is used to restrain the anchor cable 60.

[0032] The end restraint 50 is a ring or claw structure, which is linked with the locking adjustment member 40 and can be sleeved on the end of the anchor cable 60.

[0033] Using the above-mentioned device, the semi-enclosed guide channel ensures that the anchor cable is protected throughout the process, avoiding bending and damage; the combination of the hoisting interface and the support mechanism enables the overall device to be quickly hoisted and firmly fixed, reducing the time for high-altitude adjustments; the combination of locking adjustment components and end restraints provides double protection to prevent the anchor cable from slipping during transportation, significantly improving construction safety.

[0034] In order to clarify the rigid connection method between the support mechanism and the guide channel and solve the problems of easy shaking and inaccurate positioning of the device in complex slope environments, this embodiment provides an implementation method.

[0035] like Figure 2 As shown, in one embodiment, the support mechanism 30 includes:

[0036] The fixing torque 31 is located at the lower end of the semi-enclosed guide groove 10;

[0037] The fixing torque 31 is a flange or welded base, with its central axis perpendicular to the length direction of the semi-enclosed guide groove 10.

[0038] The connecting part 32 is connected to the fixing button 31 at its front end.

[0039] The front end of the connecting part 32 is connected to the fixing torque 31 via a universal joint, allowing ±30° deflection adjustment.

[0040] Using the above-mentioned device, the fixed torsion provides a stable force point, enhancing the overall integrity of the device, and the connection part realizes a modular design of the support mechanism, which facilitates folding, storage, disassembly and maintenance, and extends the life of the device.

[0041] To address the challenges of varying cable hole locations and angles on high slopes and to solve the problem of rapid and accurate alignment between the guide groove and the cable hole, this embodiment provides an implementation method.

[0042] like Figure 3 As shown, in one embodiment, the connecting portion 32 includes:

[0043] Telescopic component 33, one end of which is connected to the fixing knob 31, is used to adjust its own length;

[0044] The docking part 34 is connected to the other end of the telescopic part 33.

[0045] Using the above-mentioned device, the telescopic component can flexibly adjust the height and inclination of the guide channel to adapt to slopes with different gradients; the docking component can realize "one-click locking" of the operating platform, which greatly shortens the positioning time and improves construction efficiency.

[0046] To address the balance between cost and reliability, this embodiment provides an implementation method.

[0047] In one embodiment, the locking adjustment element is a turnbuckle.

[0048] Using the above-mentioned device, the turnbuckle has a simple structure, low cost, and strong vibration resistance, ensuring reliable anchor cable restraint / release action.

[0049] The following description, in conjunction with a preferred embodiment, illustrates the content involved in the above embodiments.

[0050] First, the construction workers placed the anchor cable into the semi-enclosed guide channel at the ground assembly station, tightened the end restraint on the end of the anchor cable, and locked it with a turnbuckle to a pre-tightening torque of 50 N·m. Then, the crane hook connected to the symmetrically distributed lifting interfaces on the semi-enclosed guide channel and lifted the device to the high-arm drilling rig operating platform at a speed of ≤1 m / s. The operators simultaneously adjusted the hydraulic cylinder of the telescopic component in the support mechanism to ensure that the deviation between the center of the guide channel outlet and the center of the slope cable hole was ≤2 mm and that the tilt angle was consistent. Next, the connecting piece at the end of the telescopic component was locked to the platform fixing interface with a spring steel anti-detachment buckle. After confirming that the positioning was correct, the trapezoidal thread handle of the turnbuckle was rotated counterclockwise 2-3 turns to release the end restraint, and the anchor cable slid into the cable hole along the guide channel. Finally, the anti-detachment buckle was pressed to release the platform lock, the telescopic component was reset to its initial length, and the device was lifted back to the ground by the crane, completing the single anchor cable installation cycle.

[0051] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
