Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to an intelligent monitoring system for dust in a high-altitude tunnel construction space. Background Art

[0002] Tunnel construction in high-altitude areas faces special environmental challenges such as low pressure, low oxygen and low temperature. The types of dust that may be generated during the construction process mainly include rock dust generated by blasting and mechanical excavation, and dust caused by the activities of construction equipment and transport vehicles. Dust monitoring and control are important links to ensure the health of construction workers and the safety of the construction environment. A corresponding dust intelligent monitoring system will be established during high-altitude tunnel construction, and dust monitors will be used for real-time monitoring. When the dust volume exceeds the predetermined value, an alarm will be issued to alert staff in relevant areas and the dust reduction system will be linked to reduce dust.

[0003] In the existing dust monitoring system, the dust monitor is generally placed directly in the construction space through a bracket to continuously monitor the dust amount in the construction space. The monitoring range of the dust monitor is limited, and the tunnel construction area is large. The amount of dust generated by construction at different locations is also different. It is often necessary to set up dust monitors at multiple points to ensure the monitoring accuracy. In order to ensure the accuracy of the monitoring data, it is necessary to set up multiple dust monitoring points and use multiple dust monitors. This means that as the progress of the tunnel project progresses, the construction space is changed, and the position of the dust monitor needs to be moved to ensure the normal operation of the entire dust intelligent detection system. The transfer of multiple dust monitors and the change and adjustment of the monitoring points are relatively cumbersome, resulting in the entire dust intelligent detection system being cumbersome to operate when the working area is changed. Therefore, the present application provides an intelligent monitoring system for dust in the construction space of a high-altitude tunnel to meet the needs. Summary of the invention

[0011] Optionally, the fixing assembly includes a bidirectional screw movably connected to the movable seat through a bearing, the outside of the bidirectional screw is provided with two sets of threads in opposite directions, and one end of the bidirectional screw extends to the outside of the movable seat and is fixedly connected to a handwheel, a partition is fixedly connected to the movable seat, symmetrically distributed clamping blocks are arranged between the partition and the limit plate, and the partition is provided with a sliding groove matching the shape of the mounting frame, and the clamping block is threadedly connected to the bidirectional screw.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a mounting frame, a moving seat and a moving wheel, multiple dust monitors can be installed at the same time through the mounting frame, and the position of the dust monitor on the mounting frame can be simply and conveniently adjusted, so that multiple dust monitors can move synchronously and change with the space of high-altitude tunnel construction. The monitoring points can be quickly adjusted and changed according to the construction situation, thereby meeting the needs of dust monitoring during high-altitude tunnel construction.

[0018] By setting the limit assembly, when the mounting frame is not locked, the position of the dust monitor between the mounting frames is determined by the limit assembly. In this state, the dust monitor will not slide freely between the mounting frames, but applying force to the dust monitor alone can also drive the dust monitor and the slide seat to produce corresponding displacement, which not only prevents the dust monitor from loosening and falling during the transfer of the entire dust concentration detection module, but also makes the adjustment operation of the monitoring point of the dust monitor easy and labor-saving.

[0019] By setting the limiting guide rail, the guide gap and the second weakened groove in the limiting assembly, the mounting frame and the limiting guide rail in the initial limiting state are mainly clamped and limited to the outside of the slide seat by the elastic force of the spring. When the slide seat is pulled to produce displacement, the mounting frame will be subjected to the tensile force to cause the spring to stretch and produce a certain displacement. At the same time, the limiting guide rail will also deform at the second weakened groove to cooperate with the displacement of the mounting frame, thereby avoiding the slide seat and making the displacement adjustment operation of the slide seat more labor-saving.

[0020] By setting the positioning blocks and positioning grooves as well as the fixing tubes and fixing columns in the limiting assembly, during the displacement adjustment process, each time the slide moves to a fixable point, the positioning blocks on the slide can form a snap connection with the positioning grooves on the limiting guide rail at that position, thereby bringing a certain resistance to the movement and adjustment process of the slide. At this time, the fixing columns on the slide correspond to the positions of the positioning grooves on the limiting guide rail, thereby helping the staff to position the slide and determine that it moves to a position where it can be fixed.

[0021] By setting the fixing column and the fixing tube in the fixing component and the limiting component, the position of the mounting frame can be locked through the adjustment of the fixing component, thereby ensuring the stability of the overall structure of the mounting frame during operation. In the process of locking displacement of the mounting frame, the fixing tube on the mounting frame is pulled to dock with the fixing column outside the sliding seat, thereby realizing the locking of the sliding seat and the dust monitor, so that the structure of the fixing component and the limiting component are matched, and the fixing structure of the position of the mounting frame and the dust monitor is cleverly matched and easy to use.

[0022] By setting up the reinforcement component, when the fixed component locks the mounting frame, the displacement of the connecting head at the end of the mounting frame drives the reinforcement component to work, so that the movable seat drives the positioning pin to sink, and the positioning pin is inserted into the soil under the movable seat, thereby forming an auxiliary fixation for the entire dust concentration monitoring module. The displacement effect of the mounting frame brought about by the use of the fixed component is further utilized, so that the correlation between the various structural components in the entire solution is stronger, the structural design is ingenious, and the operation is simple.

[0047] like Figure 1 As shown, an embodiment of the present invention provides an intelligent monitoring system for dust in a high-altitude tunnel construction space, including a dust concentration monitoring module, a harmful gas monitoring module, a temperature and humidity monitoring module, a communication system, a monitoring platform, a video monitoring system, a personnel positioning system, an alarm and a dust reduction system. The dust concentration monitoring module, the harmful gas monitoring module and the temperature and humidity monitoring module are used to monitor the dust concentration, harmful gas and temperature and humidity in the tunnel construction space respectively; the video monitoring system is used to monitor the specific working conditions of the tunnel construction space, and cooperate with the personnel positioning system to confirm the specific location of the staff in the tunnel construction space; the alarm is used to sound an alarm to remind the staff to pay attention, and the dust reduction system is used to quickly reduce the dust concentration in the tunnel construction space.

[0048] The monitoring platform is used to control and coordinate the working conditions of the equipment in the entire intelligent detection system. The dust concentration monitoring module, harmful gas monitoring module, temperature and humidity monitoring module, video monitoring system, personnel positioning system, alarm and dust reduction system and the monitoring platform all transmit signals through the communication system. The communication system is mainly composed of wireless communication facilities. The high-altitude tunnel is affected by its geographical location, with high altitude, complex terrain, many steep mountains and slopes. The long-term permafrost makes it difficult to install wired communications. Due to the obstruction of mountains and gullies, it is difficult to select lines for wired communications, the installation speed is slowed down, the line consumption is increased, and the line maintenance is difficult. Therefore, wireless communication is selected as the communication system. The above-mentioned harmful gas monitoring module, temperature and humidity monitoring module, communication system, monitoring platform, video monitoring system, personnel positioning system, alarm and dust reduction system are all existing technologies, and their principles and usage methods are the same as those of the existing technologies, which will not be elaborated here.

[0049] In this embodiment, if Figures 2 to 15 As shown, the dust concentration monitoring module includes two groups of mounting frames 1, two ends of the mounting frames 1 are provided with movable seats 2, and evenly distributed dust monitors 3 are sleeved between the mounting frames 1, and evenly distributed springs 20 are fixedly connected between the middle areas of the mounting frames 1. The springs 20 are always in a stretched state, providing a pulling force toward the dust monitors 3 for the two groups of mounting frames 1, ensuring the clamping and limiting effect of the middle area of ​​the mounting frames 1 on the dust monitors 3. The mounting frame 1 is the support and installation area of ​​the entire dust concentration monitoring module, and is used to form a frame structure for assembling the dust monitors 3, so that multiple dust monitors The detector 3 has the ability to adjust the position under the action of the mounting frame 1, and can move synchronously with the mounting frame 1 as a whole, making the displacement operation of multiple dust monitors 3 simple and convenient. The bottom end of the mobile seat 2 is provided with evenly distributed moving wheels 4, and the top of the mobile seat 2 is symmetrically installed with a limit plate 30. The outside of the limit plate 30 is fixedly connected with a push-pull rod. When the entire dust concentration monitoring module needs to be moved, holding the push-pull rod and applying force can drive the moving seat 2 and the mounting frame 1 as a whole to move under the action of the rolling moving wheels 4, thereby realizing the transfer of the position of the entire dust concentration monitoring module.

[0050] The limiting component is used for preliminary limiting the dust monitor 3 between the mounting frames 1, and the limiting component is connected to the inner side wall of the mounting frame 1; the fixing component is used for fixing the relative position between the two groups of mounting frames 1, and the fixing component is connected to the moving seat 2; the reinforcement component is used for assisting in fixing the relative position between the moving seat 2 and the ground of the tunnel construction space, and the reinforcement component is connected to the moving seat 2. The limiting component is used for preliminary limiting the dust monitor 3 between the mounting frames 1 to prevent the dust monitor 3 from sliding around at will, and plays a certain limiting role on it, but does not lock and fix the dust monitor 3. A handle is provided on the outside of the dust monitor 3, and the dust monitor 3 can be held by holding the dust The handle outside the monitor 3 can be used to pull the dust monitor 3 to make the dust monitor 3 slide between the mounting frame 1 to adjust the monitoring point of the dust monitor 3. The fixed component can lock the dust monitor 3 after the adjusted position by locking the mounting frame 1, thereby ensuring the stability of the dust monitor 3 during the subsequent monitoring work. The reinforcement component is affected by the structure in the fixed component, so that the fixed component can drive the reinforcement component to work while fixing the position of the mounting frame 1 and the dust monitor 3. After the mobile seat 2 and the mounting frame 1 are moved to the construction space of the tunnel, they are inserted into the ground of the construction space to reinforce the position of the mobile seat 2 and the mounting frame 1.

[0051] In this embodiment, if Figure 2 and Figures 10 to 15As shown, the limiting assembly includes a limiting guide rail 5 fixedly connected to the inner side wall of the mounting frame 1, a guide gap 22 is provided in the middle of the limiting guide rail 5, and a second weakened groove 24 is provided at the connection between the limiting guide rail 5 and the inner side wall of the mounting frame 1. The second weakened groove 24 makes the limiting guide rail 5 thinner and weaker at this location, so that the limiting guide rail 5 can be bent and deformed at this location after being subjected to external force. The limiting guide rail 5 is bent in a C shape toward the inner side wall of the mounting frame 1 in the area toward the guide gap 22 and forms a contact area 31. The opening makes the middle part of the limit guide rail 5 present an open structure, so that the middle area of ​​the limit guide rail 5 can be displaced after being acted upon by an external force, and then the limit guide rail 5 is deformed to a certain extent at the second weakened groove 24, so as to avoid that the structure of the limit guide rail 5 cannot be deformed, thereby generating a large resistance to the slide 25 in the initial limit state, making the position adjustment operation of the dust monitor 3 and the slide 25 laborious. At the same time, the guide gap 22 is always mounted on the outside of the fixed column 28, so as to form a limiting and guiding effect on the slide 25 during the entire adjustment process of the slide 25.

[0052] The bottom of the dust monitor 3 is sleeved with a slide 25, which is sleeved between the limiting guide rails 5. The outer side of the slide 25 is provided with a limiting convex strip 26 that matches the shape of the contact area 31, and the limiting convex strip 26 is fixedly connected with evenly distributed fixing columns 28, and the inner side wall of the mounting frame 1 is fixedly connected with a fixing pipe 23 that matches the size of the fixing column 28. The outer side of the slide 25 is provided with positioning blocks 27 that are symmetrically distributed on both sides of the limiting convex strip 26, and the outer side of the limiting guide rail 5 is provided with a positioning groove 21 that matches the shape of the positioning block 27. During the movement and adjustment process of the slide 25 and the dust monitor 3 between the limiting guide rails 5, each time the slide 25 and the dust monitor 3 move to a fixable point, the positioning block 27 on the slide 25 can be embedded in the positioning groove 21 at the position, and the staff can judge whether the slide 25 has moved to a fixable position according to the feel during the adjustment process.

[0053] During the movement and adjustment of the position of the slide 25, the limit guide rail 5 is in contact with the outside of the slide 25, and cooperates with the mounting frame 1 to form a clamping limit for the slide 25, thereby indirectly realizing the initial limit of the dust monitor 3. In this state, the mounting frame 1 only relies on the elastic force of the spring 20 to clamp the outside of the slide 25, but does not lock the slide 25. Pulling the handle on the dust monitor 3 can drive the dust monitor 3 and the slide 25 to move. During the movement, the slide 25 is in the first The second weakened grooves 24 are bent and deformed, and cooperate with the displacement of the mounting frame 1, so that the mounting frame 1 and the limiting guide rail 5 form an avoidance outside the slide 25, which is convenient for the displacement of the slide 25 between the limiting guide rails 5 and the adjustment of the monitoring point of the dust monitor 3. After the dust monitor 3 is moved to the selected monitoring point through the slide 25, the mounting frame 1 is clamped and fixed by the fixing assembly, and the fixing column 28 on the slide 25 is embedded in the fixing tube 23 to form a limiting fixation for the slide 25.

[0054] In this embodiment, if Figures 2 to 6As shown, the fixing assembly includes a bidirectional screw 14 movably connected to the moving seat 2 through a bearing, two sets of threads in opposite directions are opened on the outside of the bidirectional screw 14, and one end of the bidirectional screw 14 extends to the outside of the moving seat 2 and is fixedly connected to a hand wheel 11. The bearing between the bidirectional screw 14 and the moving seat 2 ensures that the bidirectional screw 14 can rotate in the moving seat 2. Holding the hand wheel 11 and rotating it can drive the bidirectional screw 14 to rotate. A partition 6 is fixedly connected to the moving seat 2, and a symmetrical partition is sleeved between the partition 6 and the limit plate 30. The cloth clamping block 12 is provided with a slide groove 32 which is adapted to the shape of the mounting frame 1. The opening of the slide groove 32 ensures that the mounting frame 1 can move in the moving seat 2. At the same time, the existence of the slide groove 32 also forms a limit and guide for the mounting frame 1 to a certain extent to ensure the range of movement of the mounting frame 1. The clamping block 12 is threadedly connected to the bidirectional screw 14. During the process of rotating the bidirectional screw 14, the bidirectional thread on the outside of the bidirectional screw 14 can synchronously push the two groups of clamping blocks 12 to move, so that the two clamping blocks 12 are close to or separated. Both ends of the mounting frame 1 are provided with limiting extrusion areas 15 corresponding to the positions of the clamping blocks 12. The clamping blocks 12 are U-shaped, and a first pressing surface 13 is provided on the inner side wall of the clamping blocks 12. The clamping blocks 12 are U-shaped and matched with the shapes of the limiting extrusion areas 15 on the two sets of mounting frames 1 to ensure the clamping and limiting effect of the clamping blocks 12. The outside of the limiting extrusion area 15 is provided with a first pressure surface 16 matched with the shape of the first pressing surface 13. When the two clamping blocks 12 are away from each other, there is no contact between the clamping blocks 12 and the mounting frame 1. The mounting frame 1 and the limiting guide rail 5 are in a preliminary limiting state for the dust monitor 3 and the slide 25. When the hand wheel 11 is turned to fix the position of the mounting frame 1 by the fixing assembly, the bidirectional screw 14 passes through its outer The bidirectional thread pushes the two groups of clamping blocks 12 to approach each other, and the first pressing surface 13 on the clamping block 12 is in contact with the first pressure surface 16 outside the limiting extrusion area 15, and the limiting extrusion area 15 is squeezed until the inner wall of the clamping block 12 is in contact with the outer wall of the limiting extrusion area 15, and the clamping block 12 forms a complete clamping limit for the limiting extrusion area 15, and the mounting frame 1 follows the limiting extrusion area 15 and is affected by the clamping and fixing action of the clamping block 12, and the fixing column 28 on the slide 25 passes through the guide gap 22 and is inserted into the fixing tube 23, so as to fix the slide 25, so that the mounting frame 1 is fixed through the work of the fixing component, and the position of the slide 25 and the dust monitor 3 is fixed synchronously by the displacement of the mounting frame 1 during the fixing process.

[0055] In this embodiment, if Figures 6 to 9As shown, the reinforcement component includes a movable seat 9 mounted inside the moving seat 2, and the bottom end of the movable seat 9 is fixedly connected with evenly distributed positioning pins 10, which pass through the bottom of the moving seat 2, and the length of the positioning pins 10 is greater than the height of the moving wheel 4. The length of the positioning pins 10 is such that when the positioning pins 10 are partially received inside the moving seat 2, it will not affect the normal movement of the moving wheel 4 driving the moving seat 2, and after the positioning pins 10 are completely extended from the moving seat 2, the bottom end of the positioning pins 10 can be inserted into the soil at the corresponding position below the moving seat 2, thereby forming an auxiliary fixation for the entire dust concentration monitoring module, thereby ensuring the stability of the entire module when it is fixed in the working position. The two sides of the movable seat 9 are connected and fixed to the bottom of the inner wall of the movable seat 2 by an elastic edge 17. The connection between the elastic edge 17 and the movable seat 9 is bent in a C shape and is provided with a first weakening groove 18. The setting of the first weakening groove 18 makes the thickness of the elastic edge 17 at this location thinner and weaker, so that it can be formed after being subjected to external force. When not subjected to external force, the elastic edge 17 limits the movable seat 9 by its own elastic force to keep the movable seat 9 close to the position of the partition 6 in the movable seat 2, while keeping the positioning pin 10 in the storage state in the movable seat 2.

[0056] Connecting heads 7 are provided at both ends of the mounting frame 1, and a ball wheel 8 is sleeved on the bottom of the connecting head 7. The bottom of the ball wheel 8 is in close contact with the bottom surface of the inner wall of the movable seat 2, and the end of the connecting head 7 is bent upward at 90° and contacts with the bottom surface of the partition 6. The connecting head 7 and the ball wheel 8 cooperate to form an end structure of the mounting frame 1, and a connection limit is formed between the movable seat 2 to ensure the stability of the connection between the mounting frame 1 and the movable seat 2. During the displacement adjustment of the mounting frame 1, the ball wheel 8 rolls to convert the sliding friction between the mounting frame 1 and the inner wall of the movable seat 2 into rolling friction, so that the resistance encountered by the mounting frame 1 during the displacement adjustment process is smaller, and a second pressure surface 19 is provided on the surface of the connecting head 7 close to the movable seat 9, and a second pressure surface 19 is provided on the movable seat 9. The second pressing surface 29 is adapted to the shape of the pressing surface 19. While the fixing component fixes the positions of the mounting frame 1 and the dust monitor 3, the connecting head 7 on the mounting frame 1 approaches each other following the displacement of the mounting frame 1. The second pressure-bearing surface 19 on the connecting head 7 follows the displacement of the connecting head 7 to form an extrusion on the second pressing surface 29 on the movable seat 9. After the second pressing surface 29 is extruded, the movable seat 9 is driven to sink as a whole, and the elastic edge 17 is bent and deformed at the first weakened groove 18 to cooperate with the sinking of the movable seat 9. After the movable seat 9 sinks, it drives the positioning pin 10 to descend. When the mounting frame 1 is completely fixed, the bottom end of the positioning pin 10 moves to below the bottom end of the moving wheel 4 and is inserted into the soil in the construction space, thereby forming an auxiliary fixation for the entire dust concentration monitoring module.

[0057] The working principle of the technical solution provided by the present invention is as follows: when in use, hold the handle on the outside of the moving seat 2, push the moving seat 2 and the mounting frame 1 as a whole to move to the monitoring position of the tunnel construction space under the action of the moving wheel 4, and adjust the position of the dust monitor 3 on the mounting frame 1 according to the specific conditions of the tunnel construction space. At this time, the clamping block 12 is located on the outside of the limiting extrusion area 15, and the mounting frame 1 is not limited and fixed. The limiting guide rail 5 is attached to the outside of the slide 25 under the action of its own elastic force, and the slide 25 is initially limited. To a certain extent, the slide 25 is limited, but the slide 25 is not fixed and locked. The slide 25 can slide between the limiting guide rails 5.

[0058] Holding the handle outside the dust monitor 3, the entire dust monitor 3 together with the slide 25 slides between the limit guide rails 5. During the sliding process, each time the slide 25 moves to a fixed point, the positioning block 27 on the slide 25 docks with the positioning groove 21 on the limit guide rail 5 to form a limit. Continue to pull the dust monitor 3, the mounting frame 1 will move, and drive the limit guide rail 5 away from the outside of the slide 25, releasing the limit on the slide 25, until the slide 25 moves to the specified monitoring position, and the fixed column 28 corresponds to the position of the fixed tube 23 on the mounting frame 1.

[0059] By turning the handwheel 11, the bidirectional screw 14 rotates and pushes the two groups of clamping blocks 12 to move and approach each other through the bidirectional threads on its outside. The first pressing surface 13 on the clamping block 12 is in contact with the first pressure surface 16 on the outside of the limiting extrusion area 15, and the limiting extrusion area 15 is squeezed until the inner wall of the clamping block 12 is in contact with the outer wall of the limiting extrusion area 15. The clamping block 12 forms a complete clamping limit for the limiting extrusion area 15. The mounting frame 1 follows the limiting extrusion area 15 and is affected by the clamping and fixing action of the clamping block 12. The two groups of mounting frames 1 approach each other, and the limiting guide rail 5 further squeezes and limits the outside of the slide 25. Under the action of the extrusion force, the limiting guide rail 5 bends and deforms at the second weakened groove 24, and the opening size of the guide gap 22 is further increased. The fixing column 28 on the slide 25 passes through the guide gap 22 and is inserted into the fixing tube 23 to fix the slide 25.

[0060] While the clamping block 12 clamps and fixes the limiting extrusion area 15 to fix the sliding seat 25, the connecting head 7 on the mounting frame 1 approaches each other following the displacement of the mounting frame 1, and the second pressure surface 19 on the connecting head 7 follows the displacement of the connecting head 7 to form an extrusion on the second pressing surface 29 on the movable seat 9. After the second pressing surface 29 is squeezed, the movable seat 9 is driven to sink as a whole, and the elastic edge 17 is bent and deformed at the first weakened groove 18 to cooperate with the sinking of the movable seat 9. After the movable seat 9 sinks, it drives the positioning pin 10 to descend. When the mounting frame 1 is completely fixed, the bottom end of the positioning pin 10 moves to the bottom of the movable wheel 4 and is inserted into the soil in the construction space, forming an auxiliary fixation for the entire dust concentration monitoring module.

[0061] The dust concentration monitoring module, harmful gas monitoring module and temperature and humidity monitoring module work synchronously to continuously monitor the dust concentration, harmful gases and temperature and humidity in the tunnel construction space. Once an abnormal value occurs, a signal is sent to the monitoring platform through the communication system. The monitoring platform also controls the alarm through the communication system to sound an alarm and start the dust reduction system to reduce dust. At the same time, the monitoring platform continuously remotely monitors the tunnel construction space through the video monitoring system. In case of an emergency, the location of the staff is promptly confirmed through the personnel positioning system to complete the working process of the intelligent monitoring system for dust in the entire high-altitude tunnel construction space.

[0062] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
