Description

Technical Field

[0001] This utility model relates to the field of anchor cable force gauge installation technology, specifically an auxiliary device for installing anchor cable force gauges. Background Technology

[0002] Anchor cable force gauge installation refers to the construction process of accurately and securely assembling an anchor cable force gauge (a measuring instrument used to monitor the stress state of anchor cables) into the anchor cable system. Its core purpose is to monitor the changes in anchor cable tension in real time through the force gauge, providing data support for the structural safety of projects such as geotechnical engineering, slope protection, tunnel lining, and dam reinforcement. During installation, it is necessary to ensure that the force gauge is concentrically aligned with the anchor cable axis to avoid eccentric force affecting monitoring accuracy. At the same time, it is necessary to ensure reliable connection with the anchor cable and load-bearing body, and to take measures such as waterproofing and corrosion protection to ensure accurate monitoring data and long-term stable operation of the equipment.

[0003] In the existing technology, the existing anchor cable force gauge installation auxiliary device lacks the adaptive clamping and positioning function for the size of the force gauge. It is necessary to frequently change the special clamping components for force gauges of different sizes. This not only increases the amount of tools to carry and the preparation time before installation, but may also cause the force gauge and the anchor cable axis to be misaligned due to improper clamp adjustment during the replacement process. This will affect the accuracy of the tensile force monitoring data in the later stage, especially in complex working conditions, and may prolong the installation period due to compatibility issues. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the installation of anchor cable force gauges, so as to solve the problems mentioned in the background art. Existing anchor cable force gauge installation auxiliary devices lack size adaptive clamping and positioning functions, require frequent replacement of special clamping components, which not only increases the amount of tools to carry and preparation time, but also easily leads to misalignment of the force gauge with the anchor cable axis due to improper adjustment, affecting the accuracy of monitoring data, and prolonging the installation period under complex working conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for installing an anchor cable force gauge, comprising a protective shell and four sliding grooves formed inside the protective shell. A sliding plate is slidably connected inside the sliding grooves, and a sliding rod is connected to the front end of the sliding plate. A rotating plate is rotatably connected inside the protective shell, and an arcuate groove is formed at the front end of the rotating plate. The arcuate groove is movably connected to the sliding rod. An arcuate plate is mounted on the rotating plate. A movable groove is formed at the bottom of the protective shell. A screw is connected to the bottom of the rotating plate, and a rotating ring is threaded to the outer end of the screw. A handle is connected to the end of the screw away from the rotating plate. A guide plate is connected to the bottom of the protective shell, and the rotating ring is movably connected to the guide plate. By grasping the handle and swinging it, the handle drives the screw to swing, causing the rotating plate to rotate on the protective shell. This causes the arcuate groove to drive the sliding rod to slide the sliding plate on the sliding groove. The arcuate plate clamps the anchor cable force gauge. Rotating the rotating ring makes it fit tightly against the guide plate for positioning.

[0006] In the preferred embodiment of this technical solution, the front end of the protective shell is connected to an expansion cylinder, and the outer end of the expansion cylinder is provided with a threaded groove.

[0007] Based on the preferred embodiment of this technical solution, the outer end of the threaded groove is threadedly connected to an extension cylinder, and the outer end of the extension cylinder is connected to several anti-slip strips.

[0008] In the preferred embodiment of this technical solution, the front end of the arc plate is connected to a connecting plate, which is L-shaped.

[0009] In the preferred embodiment of this technical solution, the front end of the connecting plate is connected to a gathering plate, and four gathering plates are provided.

[0010] In the preferred embodiment of this technical solution, a magnetic block is connected to the rear end of the protective shell, and a dust cover is connected to the outer end of the protective shell.

[0011] Based on the preferred embodiment of this technical solution, when the arc plate clamps the anchor cable force gauge, it drives the connecting plate to move. The movement of the connecting plate drives the converging plate to move. The four converging plates converge the anchor cable, and the extension cylinder is rotated to move on the expansion cylinder through the threaded groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the linkage structure of the rotating plate and the arc groove, the guiding design of the sliding rod and slide plate within the groove, and the adaptive layout of the arc plate, flexible clamping of force gauges of different specifications is achieved. Swinging the handle allows the arc plate to automatically adapt to the size for centering and clamping, eliminating the need for frequent clamp changes and significantly reducing tool carrying and preparation time. Simultaneously, the cooperation between the rotating ring and the guide plate ensures stable clamping, effectively avoiding axis alignment deviations. This shortens installation and debugging time, improves the accuracy of initial monitoring data, and significantly enhances the versatility and practicality of the device in installation scenarios involving multiple force gauge specifications, reducing operational difficulty in complex working conditions.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides an embodiment of an auxiliary device for installing an anchor cable force gauge, including a protective shell 1 and four sliding grooves 21 inside the protective shell 1. A sliding plate 22 is slidably connected inside the sliding grooves 21, and a sliding rod 23 is connected to the front end of the sliding plate 22. A rotating plate 24 is rotatably connected inside the protective shell 1, and an arc groove 25 is formed at the front end of the rotating plate 24, which is movably connected to the sliding rod 23. An arc plate 26 is mounted on the rotating plate 24. A movable groove 27 is formed at the bottom of the protective shell 1. A screw 28 is connected to the bottom of the rotating plate 24, and a rotating ring 29 is threadedly connected to the outer end of the screw 28. A handle 210 is connected to the end of the screw 28 away from the rotating plate 24. A guide plate 211 is connected to the bottom of the protective shell 1, and the rotating ring 29 is movably connected to the guide plate 211. The handle 210 is swung, which drives the screw 28 to swing. The screw 28 swings, causing the rotating plate 24 to rotate on the protective shell 1. This causes the arc groove 25 to drive the sliding rod 23 to slide the slide plate 22 on the slide groove 21. The arc plate 26 clamps the anchor cable force gauge. The rotating ring 29 is rotated to make it fit tightly against the guide plate 211 for positioning. By setting the linkage structure between the rotating plate 24 and the arc groove 25, combined with the sliding guide design of the sliding rod 23 and the slide plate 22 in the slide groove 21, and the adaptive clamping layout of the arc plate 26, flexible clamping of force gauges of different specifications can be achieved. When the handle 210 drives the rotating plate 24 to rotate, the arc groove 25 drives the slide plate 22 to slide synchronously through the sliding rod 23, so that the arc plate 26 automatically adapts to the size of the force gauge to complete the centering clamping without the need to change the clamp. Meanwhile, the positioning and cooperation between the rotating ring 29 and the guide plate 211 ensures stable clamping, effectively reduces axis alignment deviation, shortens installation and commissioning time, improves initial monitoring accuracy, and significantly enhances the versatility of the device in various scenarios.

[0022] Please see Figure 2-5 A further solution based on this embodiment is as follows: the front end of the protective shell 1 is connected to an extension tube 31, the outer end of the extension tube 31 is provided with a threaded groove 32, the outer end of the threaded groove 32 is threadedly connected to an extension tube 33, and the outer end of the extension tube 33 is connected to a plurality of anti-slip strips 34. The extension tube 33 provides a convenient grip for the anchor cable retraction operation, and the anti-slip strips 34 increase the friction of the hand to avoid slipping during the retraction operation, ensuring stable control of the retraction force and assisting in the precise implementation of the retraction action.

[0023] Please see Figure 1-5 A further solution based on this embodiment is as follows: A connecting plate 35 is connected to the front end of the arc plate 26. The connecting plate 35 is L-shaped, and a gathering plate 36 is connected to the front end of the connecting plate 35. Four gathering plates 36 are provided. The L-shaped connecting plate 35 stably transmits the clamping force of the arc plate 26 to the gathering plate 36. The right-angle structure ensures that the force transmission direction is accurate and that the gathering plate 36 moves synchronously with the arc plate 26, providing power linkage for anchor cable gathering. The four gathering plates 36 are symmetrically distributed and form an enclosing gathering structure as the connecting plate 35 moves. This can center and tighten the anchor cable, prevent the anchor cable from deviating, and ensure that the anchor cable is aligned with the axis of the force gauge. The core function is to achieve the gathering and positioning function.

[0024] Please see Figure 1-5 A further solution based on this embodiment is as follows: a magnetic block 37 is connected to the rear end of the protective shell 1, and a dust cover 38 is connected to the outer end of the protective shell 1. The magnetic block 37 is convenient to be adsorbed and fixed on the metal parts when the device is idle, reducing the clutter of storage. The dust cover 38 prevents dust from adsorbing on the magnetic block 37, thereby extending the service life of the magnetic block 37.

[0025] In another embodiment of this solution, the dust cover 38 can be replaced with a positioning plate with mounting screws. The magnetic block 37 is used for initial positioning, and then the mounting screws are used to fix the positioning plate in the confirmed position to improve the stability of the device.

[0026] Please see Figure 1-5 A further solution based on this embodiment is as follows: When the arc plate 26 clamps the anchor cable force gauge, it drives the connecting plate 35 to move. The movement of the connecting plate 35 drives the tightening plate 36 to move. The four tightening plates 36 tighten the anchor cable. The extension cylinder 33 is rotated so that it moves on the expansion cylinder 31 through the threaded groove 32. The tightening plate 36 is linked with the arc plate 26 to realize the clamping of the force gauge and the tightening of the anchor cable are completed synchronously, ensuring the coaxiality of the two. The position of the extension cylinder 33 can be adjusted by the thread to enhance the control force of the tightening action, assist the tightening plate 36 to tighten the anchor cable more accurately, and improve the tightening stability.

[0027] Working principle: During installation, the device is first positioned on the metal part by the magnetic block 37 at the rear end of the protective shell 1 (or the dust cover 38 can be replaced with a positioning plate and fixed with screws to enhance stability). The dust cover 38 can protect the magnet from attracting debris. During operation, hold the handle 210 and swing it to drive the screw 28 to rotate the rotating plate 24 inside the protective shell 1. The arc groove 25 on the rotating plate 24 simultaneously pushes the sliding rod 23, so that the slide plate 22 slides smoothly along the sliding groove 21, thereby driving the arc plate 26 to automatically adapt to the size of the force gauge, completing the flexible centering clamping of the anchor cable force gauge. It can adapt to different specifications of force gauges without changing the clamp. During the clamping process, the arc plate 26 simultaneously drives the four convergence plates 3 through the L-shaped connecting plate 35. 6. The moving and symmetrically enclosing clamping plate 36 forms a clamping structure, which tightens the anchor cable in the center, ensuring that the anchor cable and the axis of the force gauge are precisely aligned. After clamping, the rotating ring 29 at the outer end of the screw 28 is rotated to make it fit tightly against the guide plate 211. The clamping state is locked by positioning and locking to prevent loosening and displacement during installation. If the clamping control force needs to be adjusted, the extension tube 33 can be held and rotated (the outer anti-slip strip 34 prevents slippage). The position can be adjusted by rotating the threaded groove 32 on the expansion tube 31. The front end of the longer anchor cable can be further clamped. The whole system achieves rapid installation of the force gauge and precise positioning of the anchor cable through mechanical linkage, adaptive clamping and synchronous clamping design, which greatly improves the installation efficiency and accuracy in various scenarios.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
