Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a real-time monitoring and measurement device. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Monitoring and measurement refer to the regular observation and measurement of the deformation and stability of the surrounding rock, surface, and support structure, as well as the dynamics of the surrounding environment during tunnel construction.

[0003] Conventional tunnel monitoring and measurement is carried out manually after blasting or excavation, using measuring instruments or total stations. This method is inefficient and poses an accident risk to personnel. Currently, laser measurement is widely used for this purpose.

[0004] Chinese Utility Model Patent Publication No. CN215573050U discloses a tunnel monitoring and measurement device with dustproof function, including a monitoring and measurement equipment body and a dustproof component. The dustproof component is disposed on the monitoring and measurement equipment body and includes a support plate. The support plate has a sliding groove inside. The tunnel monitoring and measurement device with dustproof function provided by this utility model has a sealing cylinder at the bottom of the monitoring and measurement equipment body. When dustproofing the monitoring and measurement equipment body, the positioning block is rotated so that the positioning block is aligned with the sliding groove. Then the monitoring and measurement equipment body can be placed inside the sealing cylinder. Then the sealing plate is rotated so that the sealing plate seals the sliding groove, thereby preventing dust from entering the monitoring and measurement equipment body. This avoids the trouble of disassembling and removing the electronic equipment on the monitoring and measurement equipment body when a large amount of dust is generated during construction, and the trouble of fixing it during measurement.

[0005] However, as shown in the disclosed content of the patent document, the main improvement point is in the dustproof design of the device. There is still considerable room for improvement in terms of personnel safety and ease of operation. Furthermore, traditional measuring devices and methods have a low frequency, mostly once a day. When dealing with multiple measurement tasks, staff need to repeatedly adjust the measuring angle, which affects the efficiency of monitoring and measurement.

[0006] Therefore, it is urgent to develop a technical solution to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this invention is to provide a real-time monitoring and measurement device that increases the frequency of monitoring and measurement during tunnel construction, reduces manual intervention, improves construction safety, prevents dust and foreign objects from entering the housing, and enhances the stability of device operation; it also increases the measurement range of the measuring instrument, supports and provides more measurement angles, provides strong data support for the New Austrian Tunneling Method (NATM) construction of tunnels, protects the measuring device, improves the safety of equipment and materials, and overall improves the work efficiency and operational safety of tunnel measurement.

[0008] To achieve the above objectives, this utility model provides the following technical solution;

[0009] A real-time monitoring and measuring device is installed inside a protective tube. The measuring device includes a housing, a measuring instrument, and a pushing and driving device that drives the measuring instrument to extend out of the housing. The pushing and driving device is installed inside the housing, and its actuator is connected to a movable frame. A rotary driving device is installed at the movable frame, and its actuator is connected to the measuring instrument.

[0010] During measurement, the drive device moves the movable frame, which in turn causes the rotary drive device to extend out of the housing and position the measuring instrument outside the protective tube. The rotary drive device drives the measuring instrument to rotate, enabling the measuring instrument to collect multiple data points of the cross section to be measured.

[0011] Furthermore, it also includes a main frame, and the shell also includes a base plate, a sleeve, and a cylinder; the base plate and the sleeve are installed at both ends of the main frame, and a cover is rotatably installed on the sleeve; the cylinder connects the base plate and the sleeve and covers the main frame inside.

[0012] Furthermore, it also includes a cover mechanism for opening and closing the cover, and an equipment frame is also installed on the main frame. The equipment frame is used to install the cover drive device and the push drive device of the cover mechanism.

[0013] Furthermore, the main frame is also equipped with an extension frame, which is slidably connected to the movable frame. The extension frame is also provided with several expansion holes, and a backup power supply and controller are provided in the expansion holes.

[0014] Furthermore, the cover mechanism also includes a clearance rod and a transmission rod that are driven and connected to the execution end of the cover driving device; one end of the transmission rod slides into the clearance rod, and the transmission rod is rotatably connected to the cover by a cover hinge.

[0015] Furthermore, the avoidance rod has a buffer cavity, one end of the transmission rod slides into the buffer cavity and is threadedly connected to a nut, and a spring is provided in the buffer cavity. The spring is wound around the transmission rod that extends into the buffer cavity, one end of the spring abuts against the end wall of the buffer cavity, and the other end abuts against the nut. When the cover driving device is reset, the avoidance rod retracts to the limit position, and the spring is compressed and pre-tightened to pull the transmission rod to close the cover.

[0016] Furthermore, the avoidance rod is an L-shaped rod, with its short side connected to the actuator of the cover driving device, and one end of the transmission rod sliding into the long side of the avoidance rod.

[0017] Furthermore, the opening of the protective pipe is inclined in the direction of tunnel excavation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In practical use, the installation of the protective tube is relatively simple, allowing for rapid construction according to tunnel progress. It enables quick and safe deployment of measuring devices, increasing the frequency of monitoring and measurement during tunnel construction, reducing manual intervention, and improving construction safety. The casing protects the internal measuring instrument, enhancing the stability of measurement operations. The coordinated operation of the drive and rotation devices allows for multiple adjustments of the measuring instrument in multiple directions as needed, enabling multiple measurement operations and increasing the instrument's measurement range and efficiency. It also supports and provides more measurement angles to obtain more comprehensive and abundant tunnel data, providing data support for the adoption of the New Austrian Tunneling Method (NATM) in tunnel construction. The protective tube protects the measuring device awaiting retrieval after measurement, preventing rockfalls or other accidents and improving equipment safety. Overall, it improves the efficiency and operational safety of tunnel monitoring and measurement. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] refer to Figure 1-8 As shown, a real-time monitoring and measuring device is installed inside a protective tube 10. The measuring device includes a housing 1, a measuring instrument 4, and a pushing drive device 3 that drives the measuring instrument 4 to extend out of the housing 1. The pushing drive device 3 is installed inside the housing 1, and the actuator of the pushing drive device 3 is driven and connected to a movable frame 6. A rotary drive device 7 is installed at the movable frame 6, and the actuator of the rotary drive device 7 is driven and connected to the measuring instrument 4.

[0030] During measurement, the drive device 3 drives the movable frame 6 to move, which in turn drives the rotary drive device 7 to extend out of the housing 1 and position the measuring instrument 4 outside the protective tube 10. The rotary drive device 7 drives the measuring instrument 4 to rotate, so that the measuring instrument 4 can collect multiple data of the cross section to be measured.

[0031] Specifically, when the tunnel needs to be measured, the corresponding cross section to be measured and the installation point of the measuring device will be determined according to the tunnel excavation progress of tunnel 9. At the installation point, an installation hole is drilled from inside tunnel 9 into the rock stratum 91 to obtain the installation hole, which is used to install the protective pipe 10. If it is necessary to measure another interface to be measured, the measuring device can be removed from the protective pipe 10 and then installed in the protective pipe 10 at the installation point corresponding to the interface to be measured. The push drive device 3 can be an electric linear push rod, the rotary drive device 7 can be an electric rotary platform, and the measuring instrument 4 can be a laser rangefinder.

[0032] This real-time monitoring and measurement device features easy installation of a protective tube, allowing for rapid deployment according to tunnel progress. It enables quick and safe deployment of the measuring device, increasing the frequency of monitoring and measurement during tunnel construction, reducing manual intervention, and improving construction safety. The casing protects the internal measuring instrument, enhancing the stability of measurement operations. The coordinated operation of the drive unit 3 and the rotary drive unit 7 allows for multiple adjustments of the measuring instrument in multiple directions as needed, enabling multiple measurement operations. This increases the measuring instrument's measurement range and efficiency, supports and provides more measurement angles to obtain more comprehensive and abundant tunnel data, providing data support for the adoption of the New Austrian Tunneling Method (NATM) in tunnel construction. The protective tube protects the measuring device after measurement, preventing rockfalls or other accidents and improving equipment safety. Overall, it improves the efficiency and operational safety of tunnel monitoring and measurement.

[0033] In this embodiment, the main frame 21 is also included, and the shell 1 is also included, with a base plate 11, a sleeve 13 and a cylinder 12. The base plate 11 and the sleeve 13 are installed at both ends of the main frame 21, and a cover 14 is rotatably installed on the sleeve 13. The cylinder 12 connects the base plate 11 and the sleeve 13 and covers the main frame 21 inside.

[0034] Specifically, the main frame 21 can serve as the internal keel of the shell 1, safely and securely connecting the base plate 11 and the sleeve 13 to build the overall frame structure of the measuring device. It has strong stability and improves the structural strength. Together with the cylinder 12 and the cover 14, it further provides a complete structure and enhances the overall protection.

[0035] In this embodiment, a cover mechanism 5 for opening and closing the cover 14 is also included. An equipment rack 22 is also installed on the main frame 21. The equipment rack 22 is used to install the cover driving device 51 and the push driving device 3 of the cover mechanism 5.

[0036] Specifically, the cover mechanism 5 can realize the automatic opening and closing of the cover, further protecting the internal measuring instrument 4; the equipment frame 22 provides an installation position for the cover drive device 51 and the push drive device 3, optimizes the internal space layout of the housing 1, and facilitates the reduction of the overall volume to improve practicality and portability.

[0037] In this embodiment, the main frame 21 is also provided with an extension frame 23, which is slidably connected to the movable frame 6. The extension frame 23 is also provided with a plurality of extension holes 231, and a backup power supply 8 and a controller are provided on the extension holes 231.

[0038] Specifically, the expansion rack 23 has a double-sided expansion structure. One side is used to slide and connect the movable rack 6, and the other side is used to install the backup power supply 8 and the controller to avoid accidental power outages. The expansion rack 23 can also be expanded to include, but is not limited to, the backup power supply 8 that can be expanded as needed to achieve wireless operation. Through the expansion hole 231, modules including but not limited to lighting, heat dissipation, and wireless can be further expanded as needed.

[0039] The expansion rack 23 and equipment rack 22 are installed on both sides of the main frame 21, further optimizing the internal structure and making the structure more compact.

[0040] In this embodiment, the cover mechanism 5 further includes a clearance rod 52 and a transmission rod 53 that are driven and connected to the execution end of the cover driving device 51; one end of the transmission rod 53 slides into the clearance rod 52, and the transmission rod 53 is rotatably connected to the cover 14 by a cover hinge 54.

[0041] Specifically, the cover driving device 51 can be an electrically driven linear push rod. The cover driving device 51 drives the stop rod 52 to move, which in turn pushes the transmission rod 53. The transmission rod 53 pushes the cover 14 open. The cover hinge 54 is used to connect the transmission rod 53 and the cover 14 to achieve smooth opening and closing of the cover 14.

[0042] In this embodiment, the avoidance rod 52 has a buffer cavity 521. One end of the transmission rod 53 slides into the buffer cavity 521 and is threadedly connected to the nut 531. A spring 522 is provided in the buffer cavity 521. The spring 522 is wound around the transmission rod 53 that extends into the buffer cavity 521. One end of the spring 522 abuts against the end wall of the buffer cavity 521, and the other end abuts against the nut 531. When the cover driving device 51 is reset, the avoidance rod 52 retracts to the limit position, and the spring 522 is compressed and pre-tightened to pull the transmission rod 53 to close the cover 14.

[0043] Specifically, the opening and closing action of the cover 14 can be broken down as follows:

[0044] The actuator of the cover drive device 51 continuously pushes the stop rod 52, and the spring 522 is released in the buffer cavity 521 until the other end wall of the buffer cavity 521 abuts against the nut 531; the stop rod 52 pushes the nut 531, which in turn drives the cover hinge 54 to push the cover 14 open until the cover is opened to a predetermined angle. In the event of an accidental rockfall or other incident in the tunnel, the opened cover 14 can protect the measuring instrument 4 to a certain extent.

[0045] The actuator of the cover drive device 51 continuously retracts and pulls the stop rod 52. The spring 522 is compressed in the buffer cavity 521 and then pushes the nut 531 in the opposite direction, causing the transmission rod 53 to extend into the buffer cavity 521. The spring 522 compresses and pushes the nut 531 until the actuator of the cover drive device 51 retracts to the initial position. The compressed spring 522 continuously pushes the nut 531, thereby driving the cover hinge 54 to close the cover 14.

[0046] Because the spring 522 has elasticity, in the event of an unexpected power outage or drive failure, if the cover 14 is closed, the cover 14 can be opened manually, and the spring 522 will be further compressed to perform related maintenance and repair work. This also prevents the cover 14 from being unable to open due to power loss in the event of shutdown or unexpected conditions. During the opening and closing process of the cover 14, the spring 522 acts as a buffer between the stop rod 52 and the transmission rod 53, as well as a pre-tightening function for the cover 14.

[0047] In this embodiment, the avoidance rod 52 is an L-shaped rod, the short side of the avoidance rod 52 is driven to be connected to the execution end of the cover driving device 51, and one end of the transmission rod 53 slides into the long side of the avoidance rod 52.

[0048] Specifically, by adopting an L-shaped rod, the short side of the avoidance rod 52 allows the installation position of the transmission rod 53 to be closer to the housing 1, avoiding interference between the avoidance rod and the measuring instrument 4, and facilitating the transmission rod 53 to push the cover 14. The overall structure is more compact and the space utilization is more reasonable.

[0049] In this embodiment, the opening of the protective pipe 10 is inclined towards the tunnel 9 excavation direction. Specifically, the inclined orientation of the measuring pipe opening 10 can further improve the angle and distance coverage of tunnel measurements, enabling measurements to be taken at a greater distance from the completed tunnel excavation site.

[0050] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
