Description

Technical Field

[0001] This utility model belongs to the field of tunnel surrounding rock monitoring technology, specifically a tunnel surrounding rock monitoring device. Background Technology

[0002] In underground rock engineering, the surrounding rock mass whose stress state changes due to excavation is called the host rock, also known as the host rock or ore-bearing rock. The rocks surrounding the ore body and the rock mass are both called the host rock. There are generally two situations regarding the relationship between the ore body and the host rock: the boundary between the ore body and the host rock is transitional, such as the relationship between disseminated replacement ore body and the host rock.

[0003] Existing methods for monitoring tunnel surrounding rock mostly rely on total stations. Compared to levels, total stations can simultaneously measure horizontal and vertical angles and typically have higher accuracy, while levels focus on determining the horizontal line of sight. With the development of the monitoring industry, some levels have become capable of automatic measurement; however, before measurement, the total station needs to be manually leveled, which affects monitoring efficiency.

[0004] Therefore, this utility model provides a surrounding rock monitoring device for tunnels. Utility Model Content

[0010] Preferably, a positioning block is fixed to the side wall of the adjusting block, and the two positioning blocks are arranged in a corresponding manner. Through the above structure, the positioning blocks protect the adjusting block and its internal components, preventing the adjusting block from hitting the bottom of the base under its own weight, which is beneficial to protecting the safety of the equipment components and extending the service life of the equipment.

[0011] Preferably, a fixing flange is fixed to the top of the chassis, and mounting holes are provided on the side wall of the fixing flange, with multiple mounting holes arranged in a corresponding manner.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown, an embodiment of the present invention provides a tunnel surrounding rock monitoring device, including a total station 1. A base 11 is provided at the bottom of the total station 1. Rotating blocks 12 are rotatably connected to the side wall of the base 11, and three rotating blocks 12 are arranged in a circular array. An adjusting block 13 is fixedly connected to the side wall of each rotating block 12. A leveling motor 14 is fixedly connected inside the adjusting block 13, and a drive gear 15 is fixedly connected to the output end of the leveling motor 14. A transmission gear 16 meshes with the side wall of the drive gear 15. A leveling gear 18 is provided on the side wall of the adjusting block 13, and a transmission rod 17 is fixedly connected between the transmission gear 16 and the leveling gear 18. During operation, the operator can level the total station 1 by driving the leveling motor 14. During the process, whenever the leveling motor 14 fixed inside the adjusting block 13 is driven... The drive gear 15, fixed to the output end of the leveling motor 14, will rotate. At this time, since the transmission gear 16 is meshed with the drive gear 15, and the transmission rod 17 is fixed between the leveling gear 18 and the transmission gear 16, the leveling gear 18 will rotate as the leveling motor 14 drives it. This rotation causes the adjusting screw of the total station 1 to rotate through contact until the total station 1 is leveled. The base 11 serves to hold the total station 1, and the rotating block 12 connects the adjusting block 13 to the base 11. Through the above structure, the leveling motor 14 rotates the leveling gear 18, thereby leveling the total station 1. This achieves automated leveling, enhances the automation level of the total station 1, helps reduce the monitoring difficulty of surrounding rock, and improves the efficiency of surrounding rock monitoring for staff.

[0026] like Figure 1 and Figure 2As shown, a housing 2 is installed on the top of the base 11. A lifting motor 21 is fixedly connected inside the housing 2, and a lead screw 22 is fixedly connected to the output end of the lifting motor 21. A limit rod 23 is fixedly connected to the bottom of the housing 2, and the limit rod 23 is positioned corresponding to the lead screw 22. A threaded cylinder 24 and a limit block 25 are fixedly connected to the side wall of the base 11, and the threaded cylinder 24 and the lead screw 22 are threadedly connected. The limit block 25 and the limit rod 23 are slidably connected. A limit plate 26 is rotatably connected to the bottom of the lead screw 22. A connecting block 27 is fixedly connected between the housing 2 and the limit plate 26. During operation, the operator can adjust the height of the base 11 and the total station 1 placed on top of the base 11 by driving the lifting motor 21. During the process, whenever the lifting motor 21 is fixedly connected to the housing 21, the operator can adjust the height of the total station 1 placed on top of the base 11. When the internal lifting motor 21 is driven, it can move the base 11 vertically through the threaded connection between the lead screw 22 and the threaded cylinder 24, and the sliding connection between the limiting rod 23 and the limiting block 25. Whenever the total station 1 and its adjacent components descend to the bottom, the limiting plate 26 can block them. At the same time, the two connecting blocks 27 fixed between the housing 2 and the limiting plate 26 can fix the limiting plate 26. Through the above structure, the lifting motor 21 drives the lead screw 22, thereby realizing the height adjustment of the base 11, which enhances the flexibility of the equipment, helps to solve the problem of inconvenient height adjustment of the total station 1, and helps to enhance the monitoring capability of the total station 1 and improve the efficiency of surrounding rock monitoring.

[0027] like Figure 3 and Figure 5 As shown, a fixing rod 31 is slidably connected to the side wall of the adjusting block 13, and two fixing rods 31 are arranged correspondingly. A fixing handle 3 and a fixing screw 32 are respectively fixed to the two ends of the fixing rod 31. A threaded groove 33 is opened on the side wall of the base 11, and multiple threaded grooves 33 are set to correspond to the size and position of the fixing screw 32. During operation, the operator can fix the adjusting block 13 and its internal components by tightening the fixing screw 32 into the threaded groove 33 to prevent it from shifting during operation. During the process, the operator can rotate the fixing rod 31 by using the fixing handle 3 fixed to the side wall of the fixing rod 31, thereby tightening the fixing screw 32 into the threaded groove 33. Through the above structure, the fixing screw 32 and the threaded groove 33 fix the position of the adjusting block 13, thereby preventing it from detaching or shifting during operation, improving the stability of the device. The fixing handle 3 provides convenience for the operator to fix and operate, improving the convenience of the equipment.

[0028] like Figure 5As shown, a mounting rod 4 is slidably connected to the side wall of the base 11. A mounting screw 42 and a mounting handle 41 are fixed to the top and bottom of the mounting rod 4, respectively. The mounting screw 42 is threadedly connected to the total station 1. During operation, the operator can fix the total station 1 by tightening the mounting screw 42 to the bottom of the total station 1. During the process, the operator can rotate the mounting rod 4 with the help of the mounting handle 41 to tighten the mounting screw 42 to the bottom of the total station 1. Through the above structure, the mounting rod 4, mounting handle 41 and mounting screw 42 are set to fix the total station 1, while preventing the mounting rod 4, mounting handle 41 and mounting screw 42 from disengaging. This improves the stability and practicality of the equipment and helps to reduce the difficulty of operating the equipment.

[0029] like Figure 3 and Figure 4 As shown, a positioning block 5 is fixedly connected to the side wall of the adjusting block 13, and the two positioning blocks 5 are arranged correspondingly. During operation, due to the presence of the rotating block 12, the adjusting block 13 and the base 11 are rotatably connected. The operator can fix the total station 1 when the adjusting block 13 is not fixed. At the same time, whenever the adjusting block 13 rotates relative to the base 11 under its own weight, the positioning block 5 fixed to the side wall of the adjusting block 13 can prevent the adjusting block 13 from impacting the bottom of the base 11 by contacting the bottom of the base 11. Through the above structure, the positioning block 5 protects the adjusting block 13 and its internal components, and prevents the adjusting block 13 from impacting the bottom of the base 11 under its own weight, which is beneficial to protecting the safety of the equipment components and extending the service life of the equipment.

[0030] like Figure 1 As shown, a fixing flange 6 is fixedly connected to the top of the casing 2. The side wall of the fixing flange 6 is provided with mounting holes, and multiple mounting holes are arranged in a corresponding manner. During operation, the operator can leave bolts at predetermined positions and fix the fixing flange 6 to the predetermined position of the surrounding rock through the bolts and mounting holes, thereby fixing the device in the predetermined position. Through the above structure, the fixing flange 6 is set to fix the device, thereby allowing the device to be lifted off the ground. This helps to solve the problem of the difficulty in constructing surrounding rock monitoring equipment under special circumstances and enhances the applicability of the device.

[0031] like Figure 1 As shown, a gasket 7 is fixed to the top of the fixed flange 6, and the gasket 7 is set to correspond to the size of the fixed flange 6 and the mounting hole. During operation, when the worker fixes the fixed flange 6 to the surrounding rock, the gasket 7 fixed to the top of the fixed flange 6 can optimize the contact relationship between the fixed flange 6 and the surrounding rock by deforming under force. Through the above structure, the gasket 7 optimizes the contact relationship between the fixed flange 6 and the surrounding rock, which helps to improve the stability of the equipment and reduce equipment shaking.

[0032] During operation, the operator can level the total station 1 by driving the leveling motor 14. During this process, whenever the leveling motor 14, which is fixed inside the adjusting block 13, is driven, the drive gear 15, fixed to the output end of the leveling motor 14, will rotate. At this time, since the transmission gear 16 meshes with the drive gear 15, and a transmission rod 17 is fixedly connected between the leveling gear 18 and the transmission gear 16, the leveling gear 18 will rotate as the leveling motor 14 is driven. This rotation, through contact, will cause the adjusting screw of the total station 1 to rotate until the total station 1 is leveled. The base 11 serves to hold the total station 1, and the rotating block 12 connects the adjusting block. The function of base 11 and base 13 is that the height of base 11 and total station 1 placed on top of base 11 can be adjusted by driving lifting motor 21. During the process, whenever lifting motor 21, which is fixed inside the housing 2, is driven, lifting motor 21 can make base 11 move vertically by means of the threaded connection between lead screw 22 and threaded cylinder 24, and the sliding connection between limit rod 23 and limit block 25. Whenever total station 1 and its adjacent components descend to the bottom, limit plate 26 can block them. At the same time, the two connecting blocks 27 fixed between housing 2 and limit plate 26 can fix limit plate 26. Workers can fix the adjusting block 13 and its internal components by tightening the fixing screw 32 into the threaded groove 33 to prevent displacement during operation. During this process, workers can rotate the fixing rod 31 using the fixing handle 3 fixed to the side wall of the fixing rod 31, thereby tightening the fixing screw 32 into the threaded groove 33. Workers can also fix the total station 1 by tightening the mounting screw 42 into the bottom of the total station 1. During this process, workers can rotate the mounting rod 4 using the mounting handle 41, thereby tightening the mounting screw 42 into the bottom of the total station 1. Due to the presence of the rotating block 12, the adjusting block 13 and the base 11 are rotatably connected. The operator can fix the total station 1 when the adjusting block 13 is not fixed. At the same time, whenever the adjusting block 13 rotates relative to the base 11 under its own weight, the positioning block 5 fixed to the side wall of the adjusting block 13 can prevent the adjusting block 13 from impacting the bottom of the base 11 by contacting the bottom of the base 11. The operator can leave bolts at the predetermined position and fix the fixing flange 6 to the predetermined position of the surrounding rock through the bolts and mounting holes, thereby fixing the equipment in the predetermined position. During the process of fixing the fixing flange 6 to the surrounding rock, the gasket 7 fixed to the top of the fixing flange 6 can optimize the contact relationship between the fixing flange 6 and the surrounding rock by deforming under force.
