Description

Technical Field

[0001] This utility model relates to the field of mining engineering, and in particular to an anchor cable force gauge that can prevent sinking. Background Technology

[0002] In many fields such as geotechnical engineering, mining, and water conservancy and hydropower, anchor cables are widely used as a key support and reinforcement component. Anchor cable force gauges, which can prevent subsidence, are important tools for monitoring the stress state of anchor cables. Their measurement data plays a decisive role in ensuring the stability and safety of engineering structures.

[0003] Existing anchor cable force gauges designed to prevent sinking have some problems that need to be solved in practical applications. For example, during installation, due to the lack of effective fixing and adjustment devices, it is difficult to accurately position the anchor cable force gauges designed to prevent sinking, which affects the accuracy of the measurement data. When the anchor cable force gauges designed to prevent sinking are deviated, they may cause compression of the anchor cable, affecting the measurement results, or even causing damage to the anchor cable force gauges designed to prevent sinking.

[0004] Therefore, it is necessary to provide a new anchor cable force gauge that can prevent sinking to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anchor cable force gauge that can prevent sinking.

[0006] The anchor cable force gauge provided by this utility model for preventing sinking includes: a force gauge, a base plate, a telescopic structure, and a drive structure. A wire is fixedly connected to one side of the force gauge, and a controller is fixedly connected to one end of the wire. The base plate is fixedly connected to the bottom of the force gauge. Limit plates are installed at equal intervals on the side of the base plate. A telescopic structure for adjusting the telescopic length of the limit plates is installed inside the base plate. The telescopic structure includes: a rotating cylinder and a first gear. The rotating cylinder is rotatably connected at equal intervals inside the base plate. The first gear is fixedly connected to the outer wall of the rotating cylinder. A drive structure for driving the rotating cylinder to rotate is installed inside the base plate.

[0007] Preferably, the telescopic structure further includes: a threaded rod, an internal spline, a sliding groove, and an external spline. The inside of the rotating drum is threaded with a threaded rod. The outer wall of the threaded rod is provided with an internal spline. The bottom plate is provided with sliding grooves at equal intervals for the threaded rod to slide. The inside of the sliding groove is provided with an external spline. The external spline is slidably connected to the internal spline. The threaded rod slides in the sliding groove through the internal spline.

[0008] Preferably, the drive structure includes: a worm gear, a face gear, and a worm. The worm gear is rotatably connected to the bottom of the base plate, and the face gear is fixedly connected to the top of the worm gear. The face gear meshes with the first gear. The worm is rotatably connected to the bottom of the base plate, and the worm meshes with the worm gear.

[0009] Preferably, the end of the threaded rod away from the sleeve is fixedly connected to the limiting plate.

[0010] Preferably, one end of the worm gear extends out of the base plate and is fixedly connected to a knob.

[0014] Compared with related technologies, the anchor cable force gauge that can prevent sinking provided by this utility model has the following beneficial effects:

[0015] Convenient positioning adjustment:

[0016] With the help of a drive and telescopic structure consisting of a knob, worm, worm wheel, face gear, first gear, rotating drum and threaded rod, the operator can easily adjust the extension and retraction of the limit plate by simply turning the knob, thereby accurately positioning the anchor cable force gauge that can prevent sinking. The operation is simple and convenient, which greatly saves manpower and time costs and improves work efficiency.

[0017] High stability:

[0018] The unique anti-sinking and positioning adjustment principle allows the limiting plate to fit tightly with the surrounding support structure according to the actual situation, providing stable support force and effectively preventing the anchor cable force gauge from sinking or shifting during operation. This ensures the stability and continuity of measurement data and guarantees the smooth progress of measurement work even in complex geological conditions and harsh working environments.

[0024] 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 for explaining the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 4 An anchor cable force gauge that can prevent sinking includes: a force gauge 1, a base plate 4, a telescopic structure and a drive structure. A wire 2 is fixedly connected to one side of the force gauge 1, and a controller 3 is fixedly connected to one end of the wire 2. The base plate 4 is fixedly connected to the bottom of the force gauge 1. Limiting plates 5 are installed at equal intervals on the side of the base plate 4. A telescopic structure for adjusting the telescopic length of the limiting plates 5 is installed inside the base plate 4. The telescopic structure includes: a rotating cylinder 6 and a first gear 7. The rotating cylinder 6 is rotatably connected at equal intervals inside the base plate 4. The first gear 7 is fixedly connected to the outer wall of the rotating cylinder 6. A drive structure for driving the rotating cylinder 6 to rotate is installed inside the base plate 4. A protective cylinder 16 for protecting the worm gear 14 is fixedly connected to one end of the base plate 4 near the worm gear 14. The four corners of the bottom of the base plate 4 are designed with bevels, and the plane of the bevels is parallel to the side of the limiting plates 5.

[0027] It should be noted that the protective sleeve 16 effectively protects the part of the worm gear 14 that extends out of the base plate 4, avoiding damage from debris such as gravel, ensuring the normal operation of the drive structure, reducing equipment failures and maintenance frequency, extending the overall service life of the anchor cable force gauge 1, and reducing equipment replacement and maintenance costs.

[0028] Please see Figure 1 and Figure 4 The telescopic structure also includes: threaded rod 8, internal spline 9, sliding groove 10 and external spline 11. The rotating cylinder 6 is threaded with threaded rod 8 inside. The outer wall of the threaded rod 8 is provided with internal spline 9. The bottom plate 4 is provided with sliding groove 10 at equal intervals for the threaded rod 8 to slide. The sliding groove 10 is provided with external spline 11 inside. The external spline 11 is slidably connected with the internal spline 9. The threaded rod 8 slides in the sliding groove 10 through the internal spline 9. The end of the threaded rod 8 away from the sleeve is fixedly connected to the limiting plate 5.

[0029] It should be noted that the sliding connection between the internal spline 9 and the external spline 11 prevents the threaded rod 8 from rotating with the rotation of the sleeve, restricting the threaded rod 8 to slide only along the long axis of the external spline 11. By rotating the sleeve, the threaded rod 8, which is threadedly connected to the sleeve, can be extended or retracted, thereby controlling the movement of the limiting plate 5.

[0030] Please see Figure 1 and Figure 4 The drive structure includes: a worm gear 12, a face gear 13, and a worm 14. The worm gear 12 is rotatably connected to the bottom of the base plate 4, and the face gear 13 is fixedly connected to the top of the worm gear 12. The face gear 13 meshes with the first gear 7. The worm 14 is rotatably connected to the bottom of the base plate 4 and meshes with the worm gear 12. One end of the worm 14 extends out of the base plate 4 and is fixedly connected to a knob 15. The side wall of the knob 15 is provided with anti-slip texture.

[0031] It should be noted that the anti-slip texture on the side wall of knob 15 increases friction, making it easier for staff to operate. Even in complex working environments, knob 15 can be easily turned to adjust the equipment, improving the operating experience and work efficiency.

[0032] The working principle of the anchor cable force gauge that prevents sinking provided by this utility model is as follows:

[0033] Measurement principle:

[0034] When the anchor cable is under stress, the force is transmitted to the force sensor 1. The force sensor 1 converts the sensed force into an electrical signal, which is transmitted to the controller 3 through the wire 2 fixedly connected to one side of the sensor. The controller 3 analyzes and processes the received electrical signal and finally displays the stress value of the anchor cable in an intuitive digital or graphical form, thereby achieving accurate monitoring of the stress state of the anchor cable.

[0035] Principles of preventing sinking and adjusting positioning:

[0036] To prevent the anchor cable dynamometer from sinking and achieve accurate positioning, the operator only needs to turn the knob 15, which is fixedly connected to one end of the worm 14. Since the worm 14 and the worm wheel 12 are meshed, when the knob 15 drives the worm 14 to rotate, the worm wheel 12 will also rotate. The face gear 13, which is fixedly connected to the top of the worm wheel 12, will also rotate. The face gear 13 will then mesh with the first gear 7, thereby driving the first gear 7 to rotate. This will cause the rotating cylinder 6, which is fixedly connected to the first gear 7, to start rotating. The rotating cylinder 6 is internally threaded with a threaded rod 8, and the threaded rod 8 has internal splines on its outer wall. The threaded rod 8 is slidably connected to the external spline 11 in the groove 10 of the base plate 4. This restricts the threaded rod 8 to slide only along the long axis of the external spline 11 and not to rotate with the rotating drum 6. As the rotating drum 6 rotates, the threaded rod 8 performs telescopic movement. Because the end of the threaded rod 8 away from the rotating drum 6 is fixedly connected to the limiting plate 5, the limiting plate 5 will move with the telescopic movement of the threaded rod 8. By adjusting the position of the limiting plate 5, it can be made to make close contact with the surrounding support structure, thereby providing stable support force, effectively preventing the anchor cable force gauge from sinking, and achieving accurate positioning.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. 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.
