Description

Technical Field

[0001] This utility model relates to the field of surrounding rock loosening zone technology, specifically a surrounding rock loosening zone measuring device. Background Technology

[0002] The loosening zone of the surrounding rock has a different meaning from the collapse arch and collapse height. The inner boundary of the loosening zone is measured from the surface of the roadway where the radial stress is zero. The size of the loosening zone is mainly related to the strength of the surrounding rock and the original rock stress. When the original rock stress is the same, the loosening zone is larger when the surrounding rock strength is low, and vice versa.

[0003] However, existing measuring equipment requires manual handling for measurement and testing. If it is accidentally dropped, it will damage the measuring device, resulting in inaccurate measurement results, reduced measurement precision, and decreased testing efficiency.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN209673789U discloses a tunnel surrounding rock loosening zone measuring device with good protective effect. The device includes a measuring device body, with concave blocks movably connected to both sides. A first spring is fixedly connected to the top and bottom of the left side of the movable rod. The left side of the first spring is fixedly connected to the inner wall of a fixed plate. A first sliding groove is formed at the top and bottom of the inner cavity of the fixed plate, near the clamping rod. A fixed plate is fixedly connected to the top of the measuring device body. Both sides of the top of the plate are equipped with tie rods. Through the coordinated use of concave blocks, fixed plates, tie rods, pull blocks, trapezoidal blocks, sliding rods, transmission rods, pulleys, movable rods, and locking rods, the transmission rods are engaged in the inner cavity of the fixed grooves, and the locking rods are engaged in the inner cavity of the locking grooves. This achieves the effect of preventing the device from falling and being damaged. It solves the problem that existing measuring devices for loosened rock zones require manual handling for measurement and testing, and that accidental drop will damage the measuring device and lead to inaccurate measurement results. This enhances the accuracy of the measurement and improves the efficiency of the test.

[0005] The aforementioned device utilizes the cooperation of multiple components to prevent damage from falling during use. However, the assembly and cooperation of these multiple components increases the manufacturing cost of the equipment and the difficulty of subsequent maintenance. Utility Model Content

[0006] The purpose of this utility model is to provide a measuring device for loosened rock, so as to solve the problems mentioned in the background art, such as the loosened rock measuring device being prone to damage due to falling, resulting in inaccurate measurement, low detection efficiency, and some protective devices having high manufacturing costs and difficult maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for loosened rock rings, comprising a fixing plate, an mounting base and a fixing base being provided on the upper surface of the fixing plate, the fixing base being provided on the side end of the mounting base, and a connecting rod being provided on the inner side of the fixing base; a protective shell being provided on the outer surface of the connecting rod, and a detection mechanism for easy protection being provided on the inner side of the protective shell.

[0008] Furthermore, a buffer spring is provided at the end of the connecting rod away from the protective shell, and a fixing seat is provided on the outer surface of the buffer spring.

[0009] Furthermore, a buffer rod is provided on the inner side of the fixed base, and a connecting rod is provided on the outer surface of the buffer rod.

[0010] Furthermore, the testing mechanism includes a testing instrument, which is disposed on the inner side of the first protective shell, and a second protective shell is disposed at the end of the testing instrument away from the first protective shell.

[0011] Furthermore, a movable rod is provided on the outer surface of the second protective shell, and a positioning seat is provided on the outer surface of the movable rod.

[0012] Furthermore, a fixed seat is provided on the outer surface of the positioning seat, a helical rod is provided on the inner side of the positioning seat, and a rotating rod is provided on the outer surface of the helical rod.

[0013] Furthermore, a helical rod is provided on the outer surface of the rotating rod, and the helical rod is located at the output end of the servo motor.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) Through the detection mechanism, the accurate measurement and effective protection of the loosened zone of the surrounding rock are realized. The detector, as the core component, is firmly placed between the first protective shell and the second protective shell. This double-layer protection structure not only enhances the impact resistance of the detector, but also prevents damage caused by accidental drop or collision, thereby ensuring the accuracy and reliability of the measurement data. (2) The movable rod on the outer surface of the protective shell is combined with the positioning seat, which enables the detection mechanism to be flexibly adjusted and positioned according to actual measurement needs, further improving the flexibility and efficiency of measurement. In addition, the use of the screw rod and the rotating rod, driven by the servo motor, realizes the automatic rotation and precise positioning of the detection mechanism, which greatly simplifies the operation process and reduces the difficulty and error of manual operation; (3) The buffer springs and buffer rods effectively absorb the impact force that may be generated during the use of the equipment, further protecting the detection mechanism from damage. At the same time, the design of these buffer components also takes into account the stability and durability of the equipment, ensuring the stable performance of the equipment under long-term use. (4) The synergistic effect of the buffer spring and the buffer rod not only provides buffering when the equipment is subjected to vertical impact, but also reduces the impact of vibration in the horizontal direction, which significantly improves the adaptability and reliability of the equipment in complex geological environments.

[0017] 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.

[0018] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: a measuring device for loosened rock rings, including a fixing plate 1, an mounting base 2 and a fixing base 3 on the upper surface of the fixing plate 1, the fixing base 3 being disposed on the side end of the mounting base 2, and a connecting rod 4 being disposed on the inner side of the fixing base 3; a protective shell 5 being disposed on the outer surface of the connecting rod 4, and a detection mechanism for easy protection being disposed on the inner side of the protective shell 5.

[0019] The detection mechanism allows for precise measurement of the loosened rock zone. The protective shell 5 effectively prevents external factors from interfering with or damaging the detection mechanism. When the equipment is subjected to external impact, the buffer spring 6 acts as a shock absorber, reducing damage to the internal structure. The fixed seat 3 on the outer surface of the buffer spring 6 ensures stable installation. The buffer rod 7 on the inner side of the fixed seat 3, in conjunction with the connecting rod 4, further enhances the equipment's buffering capacity under external force, improving its stability and durability. The detector 8 in the detection mechanism is located inside the protective shell 5, preventing direct exposure to the external environment and reducing the impact of dust and moisture, ensuring normal operation and measurement accuracy. The movable rod 10 on the outer surface of the protective shell 9 allows for flexible adjustment of its position, facilitating operation and maintenance of the detector 8. The positioning seat 11 on the outer surface of the movable rod 10 ensures the protective shell 9 remains stable after adjustment. The rotating rod 13 drives the spiral rod 12 to rotate, enabling precise adjustment of the positioning seat 11 and better control of the protective shell 9's position.

[0020] Example 2: Based on Example 1, please refer to... Figure 2 - Figure 5 The buffer rod 7 is also disclosed, and its specific structure is as follows: a buffer spring 6 is provided at the end of the connecting rod 4 away from the protective shell 5, a fixed seat 3 is provided on the outer surface of the buffer spring 6, a buffer rod 7 is provided on the inner side of the fixed seat 3, a connecting rod 4 is provided on the outer surface of the buffer rod 7, and the detection mechanism includes a detector 8, which is located on the inner side of the protective shell 5, and a protective shell 9 is provided at the end of the detector 8 away from the protective shell 5.

[0021] Depend on Figure 4 It can be seen that the buffer rod 7, together with the connecting rod 4, the buffer spring 6, and the fixed seat 3, constitute a multi-level buffer system. When the equipment encounters an external impact, the buffer spring 6 first absorbs part of the impact energy, and then the buffer rod 7 further dissipates the residual stress through its own deformation. This graded buffer mechanism significantly reduces the direct impact of the impact force on the core detection mechanism. The specially designed buffer rod 7 is made of a high-elasticity alloy material, and its surface is specially treated to form a friction-reducing coating, which not only ensures the structural stability under repeated deformation, but also reduces the frictional loss between it and the connecting rod 4, effectively extending the service life of the equipment.

[0022] Example 3: Based on Example 1, please refer to... Figure 3 - Figure 6The movable rod 10 was also disclosed, and its specific structure is as follows: the outer surface of the protective shell 2 9 is provided with the movable rod 10, the outer surface of the movable rod 10 is provided with the positioning seat 11, the outer surface of the positioning seat 11 is provided with the fixed seat 3, the inner side of the positioning seat 11 is provided with the spiral rod 12, the outer surface of the spiral rod 12 is provided with the rotating rod 13, the outer surface of the rotating rod 13 is provided with the spiral rod 12, and the spiral rod 12 is located at the output end of the servo motor 14.

[0023] Depend on Figure 6 It can be seen that the protective combination formed by the protective shell 2 9 and the movable rod 10, through the precise cooperation of the positioning seat 11 and the screw rod 12, realizes the reliable protection of the detector 8 under complex working conditions. At the same time, the rotating rod 13 driven by the servo motor 14 ensures the smoothness and positioning accuracy of the adjustment process. While maintaining a compact structure, it greatly improves environmental adaptability and ease of operation.
