DETAILED DESCRIPTION

[0021] The following is combined with Figure 1 -Attached Fig. 9 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Example 1: If an existing integrated tunnel monitoring device fails while working in a highway tunnel, due to the high location of the integrated tunnel monitoring device in the tunnel, when maintenance personnel repair or inspect the integrated tunnel monitoring device, the maintenance personnel need to carry the climbing device back and forth and climb up and down many times. This process will consume a lot of the maintenance personnel's time, causing the equipment to be in a faulty state for a long time, affecting the normal monitoring and emergency response functions of the tunnel.

[0023] An integrated tunnel monitoring device that is easy to maintain, please refer to the attached Figure 1 -Attached Figure 5As shown, it includes: a track 1, a patrol body 2 is arranged on one side of the track 1, two rotating frames 3 are rotatably connected to the patrol body 2, a rotating block 4 is rotatably connected to the rotating frame 3, a torsion spring is arranged at the rotation connection between the rotating frame 3 and the rotating block 4, and electric rollers are arranged on the rotating frame 3 and the rotating block 4, and the electric rollers on the rotating frame 3 and the rotating block 4 are in contact with the track 1; a fixed plate 5 is fixedly connected to the patrol body 2, a connecting frame 6 is arranged on the fixed plate 5, and the connecting frame 6 is provided with a supporting shell 7; two winding shafts 8 are both rotatably connected to the supporting shell 7, and the winding shafts 8 are wound with a first pull rope 9 and a second pull rope 10, and the first pull rope 9 and the second pull rope 10 both penetrate the connecting frame 6 and the supporting shell 7, and the first pull rope 9 and the second pull rope 10 are both in contact with the fixed plate 5. The fixed plate 5 is fixed; the control mechanism is arranged on the support shell 7, and is used to control the fixed plate 5 to drive the inspection body 2 to move; the unlocking mechanism is arranged on the upper part of the support shell 7, and is used to control the rotation of the rotating block 4; the locking mechanism is arranged in the support shell 7, and is used to lock the position of the support shell 7. The control mechanism includes: two motors 201, both of which are fixed to the support shell 7, and the output shaft of the motor 201 is fixed to the winding shaft 8, which is used to actively control the retraction and extension of the first pull rope 9 and the second pull rope 10; four fixed columns 202, both of which are fixed to the lower side of the connecting frame 6, and the fixed columns 202 are slidably matched with the fixed plate 5, and the first pull rope 9 and the second pull rope 10 respectively penetrate the adjacent fixed columns 202, which are used to maintain the stability of the inspection body 2 during the up and down movement.

[0024] In the above scheme, the problem that the inspection body 2 is located at a high position in the tunnel and the maintenance personnel need to carry the climbing device back and forth and climb up and down many times when working is solved; the device is provided with a control panel outside (which is an existing mechanism, not shown in the figure, and is manually operated by the maintenance personnel to control the device at close range through the control panel), the motor 201 and the unlocking mechanism are both connected to the control panel signal, the motor 201 is a stepping motor 201, and when the motor 201 is not started, its output shaft does not rotate under the action of external force, so that the first pull rope 9 and the second pull rope 10 are always in a taut state, ensuring that the fixing plate 5 and the connecting frame 6 are The relative position does not change. The fixed plate 5 is composed of a rectangular plate and four cylinders. The four cylinders on the fixed plate 5 are located at the four corners of the rectangular plate. The ends of the first pull rope 9 and the second pull rope 10 are respectively connected to the inner bottom surfaces of the adjacent cylinders on the fixed plate 5. The two first pull ropes 9 and the two second pull ropes 10 are synchronously retracted and released through two winding shafts 8, so that the inspection body 2 maintains a horizontal state when moving up and down, allowing maintenance personnel to perform daily inspections and fault repairs on the device while standing on the ground. The support shell 7 is U-shaped, and the support shell 7 does not contact the track 1 during the movement of the inspection body 2.

[0025] A rectangular hole is provided at the center of the connecting frame 6, and the rotating frame 3 and the rotating block 4 pass through the rectangular hole of the connecting frame 6. When the inspection body 2 is lowered, the locking mechanism controls the supporting shell 7 to act as a fulcrum through the track 1, so that the inspection body 2 moves downward at a uniform speed. The fixed column 202 is located in the cylinder on the fixed plate 5, and is used to make the inspection body 2 translate first and then lower when it leaves the track 1. At the same time, when the inspection body 2 is reset, the closer it is to the track 1, the more stable its own state is, which facilitates the restoration of the relative position of the electric roller on the track 1 and the rotating block 4.

[0026] Workflow: When the device is used to monitor a highway tunnel, if the device fails and cannot be moved or undergoes routine maintenance, the operator first holds the control panel close to the bottom of the inspection body 2, and then uses the control panel to release the relative fixed state of the rotating frame 3 and the rotating block 4. The rotating block 4 rotates to make the electric roller on it lose contact with the track 1. At the same time, the locking mechanism fixes the support shell 7 on the track 1. The weight of the inspection body 2 acts on the first pull rope 9 and the second pull rope 10 through the fixing plate 5. The output shaft of the motor 201 is self-locking, and the winding shaft 8 does not rotate. Then the maintenance personnel start the two motors 20 through the control panel. 1. The output shaft of the motor 201 drives the winding shaft 8 to rotate, and the two winding shafts 8 rotate synchronously to release the first pull rope 9 and the second pull rope 10. The two first pull ropes 9 and the two second pull ropes 10 simultaneously suspend the four corners of the four fixed plates 5 for lowering operation. The fixed column 202 gradually moves out of the cylinder of the fixed plate 5, and the fixed plate 5 drives the inspection body 2 to move downward first. The rotating frame 3 and the rotating block 4 pass through the rectangular hole of the connecting frame 6, and then slowly move downward through the first pull rope 9 and the second pull rope 10. When the inspection body 2 moves to a position convenient for maintenance personnel to operate, the control panel turns off the motor 201, and the operator performs maintenance operations on the inspection body 2.

[0027] When the maintenance personnel complete the inspection of the inspection body 2, they restart the motor 201 through the control panel, the output shaft of the motor 201 reverses, the motor 201 winds up the first pull rope 9 and the second pull rope 10 through the winding shaft 8, the first pull rope 9 and the second pull rope 10 gradually pull the fixed plate 5 upward, and the inspection body 2 gradually returns to its initial position. As the inspection body 2 approaches the track 1, the four fixed columns 202 guide the two first pull ropes 9 and the two second pull ropes 10, so that the shaking of the fixed plate 5 gradually disappears, the fixed column 202 is reinserted into the cylinder on the fixed plate 5, the rotating frame 3 passes through the rectangular hole of the connecting frame 6 again and returns to its initial position, the control panel controls the unlocking mechanism to reset, the rotating block 4 rotates and resets, the locking mechanism resets synchronously, the support shell 7 loses contact with the track 1 and returns to its initial state, at this point all parts return to their initial positions, the inspection body 2 moves along the track 1, and continues to monitor the interior of the highway tunnel.

[0028] Please refer to the attached Figure 1 -Attached Figure 3 , Attachment Figure 5 and attached Figure 6 As shown, the unlocking mechanism includes: a first electric push rod 301, fixedly connected to the support shell 7, a connecting plate 302 fixedly connected to the telescopic end of the first electric push rod 301, the connecting plate 302 fixedly connected to two fixed support plates 303, a sliding plate 304 slidably connected to the lower part of the fixed support plate 303, a spring fixedly connected between the sliding plate 304 and the fixed support plate 303; four limit bending plates 305, respectively slidably connected to the upper part of the corresponding rotating frame 3, the limit bending plates 305 and the sliding plates 304 Extrusion fit, a spring is fixedly connected between the limit bend plate 305 and the rotating frame 3, a blind hole is provided on the rotating block 4, the blind hole of the rotating block 4 is limited by the limit bend plate 305, the rotating block 4 is limited by the limit bend plate 305, and the connection state of the inspection body 2 and the track 1 is controlled. The unlocking mechanism also includes: four reset bend plates 401, which are respectively fixedly connected to the corresponding limit bend plates 305, and the reset bend plate 401 is extruded and fitted with the rotating block 4 to assist the rotating block 4 in rotating and resetting.

[0029] In the above scheme, the purpose is to quickly release the contact state between the electric roller on the rotating block 4 and the track 1, so that the inspection body 2 can move down smoothly, and at the same time restore the connection between the electric roller and the track 1 after the inspection body 2 is reset; a sliding plate 304 and the two limit bending plates 305 on its lower side are squeezed and matched at the same time, which is used to simultaneously release the limit of the four limit bending plates 305 on the four rotating blocks 4, and the two fixed support plates 303 are respectively located on the front and rear sides of the connecting plate 302 and are distributed in a mirror image. The fixed support plate 303 and the sliding plate 304 are not in contact with the track 1, the first electric push rod 301 is connected to the control panel signal, and the distance between the sliding plate 304 and the limit bending plate 305 on its lower side is smaller than the telescopic distance of the telescopic end of the first electric push rod 301, which is used to make the inspection body 2 move downward smoothly, and the electric roller on the rotating block 4 can be connected to the track 1 smoothly. When the inspection body 2 is reset, the rotating block 4 rotates in advance, which makes it easier for the electric roller on the rotating block 4 to resume contact with the track 1. The elastic coefficient of the spring connected to the sliding plate 304 is greater than the elastic coefficient of the spring connected to the limit bent plate 305. The torsion spring at the connection between the rotating frame 3 and the rotating block 4 is always in a power storage state, so that the two rotating blocks 4 on the same rotating frame 3 swing away from each other under the action of the torsion spring elastic force after the limit contact. The upper side of the reset bent plate 401 is in an inclined state, and the spacing between the inclined parts of the two reset bent plates 401 at the same rotating frame 3 gradually decreases from top to bottom. By moving the limit bent plate 305, the limit of the rotating block 4 is quickly released, so that the inspection body 2 loses connection with the track 1, ensuring the stability of the connection state between the track 1 and the inspection body 2.

[0030] Working process: When the maintenance personnel inspect the device, the operator starts the first electric push rod 301 through the control panel, and the telescopic end of the first electric push rod 301 drives the connecting plate 302 to move downward, and the connecting plate 302 drives the sliding plate 304 to move downward through the fixed support plate 303, and the sliding plate 304 gradually approaches the two limit bent plates 305 below it, and then the sliding plate 304 contacts and pushes the limit bent plate 305 to move downward, and the limit bent plate 305 compresses the connected spring, and the limit bent plate 305 moves out of the blind hole of the rotating block 4, and the limit of the rotating block 4 is released, and the limits of the four rotating blocks 4 are released synchronously, and the inspection body 2 loses the connection with the track 1, and when the limit bent plate 305 moves downward to the limit, the fixed support plate 303 continues to move downward, and the spring between the fixed support plate 303 and the sliding plate 304 is compressed.

[0031] When the telescopic end of the first electric push rod 301 is extended to the limit, the control panel closes the first electric push rod 301, and then the above-mentioned lowering and maintenance operations of the inspection body 2 are repeated. As the inspection body 2 moves downward, the sliding plate 304 moves downward under the elastic force of the connected spring. When the sliding plate 304 loses contact with the limit bent plate 305, the limit bent plate 305 moves upward relative to the rotating frame 3 under the elastic force of the connected spring. The limit bent plate 305 pushes the rotating block 4 to swing and reset through the reset bent plate 401. The torsion spring connected to the rotating block 4 twists and stores force, and the limit bent plate 305 is reinserted into the blind hole of the rotating block 4. When the inspection of the inspection body 2 is completed, the above-mentioned reset operation of the inspection body 2 is repeated. In the process of the rotating frame 3 approaching the track 1, the sliding plate 304 pushes the limit bent plate again. 305 moves, the limits of the four rotating blocks 4 are released and they swing under the elastic force of the torsion spring, and at the same time, the limit bent plate 305 pushes the sliding plate 304 to move upward, and the sliding plate 304 re-compresses the connected spring. When the inspection body 2 returns to its initial position, the maintenance personnel controls the telescopic end of the first electric push rod 301 to retract and reset through the control panel, and the connecting plate 302 drives the fixed support plate 303 to move and reset, and the spring connected to the sliding plate 304 stretches, and the sliding plate 304 loses contact with the limit bent plate 305. Under the elastic force of the spring connected to the limit bent plate 305, the rotating block 4 is swung and reset through the reset bent plate 401, and the electric roller on the rotating block 4 and the track 1 return to the initial contact state, and the track 1 and the inspection body 2 return to the initial connection state. At this point, all parts are restored to their initial state and wait for the next maintenance.

[0032] Please refer to the attached Figure 6 and attached Figure 7As shown, the locking mechanism includes: two rotating plates 501, which are rotatably connected to the support shell 7, and a torsion spring is provided at the rotation connection between the rotating plate 501 and the support shell 7. The rotating plate 501 is rotatably connected to the friction plate 503, and the friction plate 503 is pressed and matched with the track 1 to fix the position of the support shell 7 on the track 1; a sliding frame 502, which is slidably connected to the connecting plate 302, and a spring is fixed between the connecting plate 302 and the sliding frame 502, and the sliding frame 502 is pressed and matched with the friction plate 503 to actively control the friction plate 503 and the sliding frame 502 to move the sliding frame 502 to the support shell 7. The track 1 is fitted, the sliding frame 502 is provided with two inclined surfaces distributed in a mirror image, the spacing between the two inclined surfaces of the sliding frame 502 gradually decreases from top to bottom, the inclined surface of the sliding frame 502 is pressed and matched with the friction plate 503, and the torsion spring at the rotating connection between the rotating plate 501 and the support shell 7 is always in a power storage state, so that the friction plate 503 is suspended and does not actively contact the track 1, and the locking mechanism also includes: two limit plates 601, both fixed to the lower side of the connecting plate 302, the limit plates 601 are pressed and matched with the track 1, and are used to assist in limiting the position of the support shell 7. According to claim 8, an integrated tunnel monitoring device that is easy to maintain, the minimum spacing between the two limit plates 601 is equal to the width of the track 1, the lower part of the limit plate 601 is in an inclined state, and the spacing between the inclined parts of the two limit plates 601 gradually increases from top to bottom, which is used to fix the support shell 7 in the center on the track 1.

[0033] In the above scheme, it is intended to solve the problem that during the lowering process of the inspection body 2, the support shell 7 moves on the track 1, causing the inspection body 2 to shake significantly; the torsion spring at the rotating connection between the rotating plate 501 and the support shell 7 is always in a power storage state, and the friction plate 503 does not contact the track 1, which hinders the normal movement of the inspection body 2 on the track 1, and the projection of the swing range of the opposite ends of the two rotating plates 501 on the horizontal plane is always within the range of the projection of the two inclined surfaces of the sliding frame 502 on the horizontal plane. The elastic coefficient of the spring connected to the sliding frame 502 is greater than the elastic coefficient of the torsion spring connected to the rotating plate 501, and the cross-section of the friction plate 503 is L-shaped, which is used to increase the contact area between the friction plate 503 and the track 1.

[0034] Working process: during the extension of the telescopic end of the first electric push rod 301, the telescopic end of the first electric push rod 301 drives the connecting plate 302 to move downward, and the connecting plate 302 drives the sliding frame 502 to move downward through the spring, and the two inclined surfaces of the sliding frame 502 push the two rotating plates 501 to swing downward, and the torsion spring connected to the rotating plate 501 is twisted, and the rotating plate 501 makes the friction plate 503 contact and fit the track 1, and the friction plate 503 fixes the support shell 7 on the track 1 in the left and right directions through the fit and friction with the track 1. When the track 1 contacts the sliding frame 502, the spring connected to the sliding frame 502 is compressed, and the support shell 7 is fixed in the up and down directions on the track 1. When the connecting plate 302 moves downward to the limit, the first electric push rod 3 01 is fully extended, the first electric push rod 301 is closed, and the connecting plate 302 fixes the support shell 7 in the front and rear directions on the track 1 through two limit plates 601. At this point, the position of the support shell 7 on the track 1 is completely fixed, ensuring the stability of the inspection body 2 during the lowering for maintenance or inspection. When the inspection body 2 is repaired or inspected, the telescopic end of the first electric push rod 301 is retracted and reset, the connecting plate 302 and the limit plate 601 are moved and reset, the spring connected to the sliding frame 502 is extended, the sliding frame 502 is moved and reset and loses contact with the friction plate 503, the rotating plate 501 is swung and reset under the action of the torsion spring elastic force, and the friction plate 503 loses contact with the track 1. At this point, all parts are reset and wait for the next maintenance.

[0035] In the above embodiment, the connection relationship between the connection frame 6 and the support shell 7 can be regarded as a fixed connection. However, in the lower embodiment, the connection relationship between the connection frame 6 and the support shell 7 is a rotational fit.

[0036] Example 2: Based on Example 1, please refer to the attached Figure 2 , Attachment Figure 8 and attached Fig. 9 As shown, it also includes: a stable reset mechanism, which is arranged on the support shell 7, and is used to control the inspection body 2 to move downward stably. The stable reset mechanism includes: a second electric push rod 701, which is rotatably connected to the support shell 7, and the telescopic end of the second electric push rod 701 is rotatably connected to the connecting frame 6. The connecting frame 6 and the support shell 7 are rotatably matched to control the relative state of the connecting frame 6 and the support shell 7; two weight blocks 702, which are both rotatably connected to the connecting frame 6, and two sliding support plates 703 are slidably connected to the connecting frame 6. A spring is fixed between the sliding support plate 703 and the connecting frame 6, and the sliding support plate 703 is squeezed and matched with the weight block 702, and the sliding support plate 703 is squeezed and matched with the support shell 7, and is used to change the rotation center of the connecting frame 6 according to the tilt direction of the support shell 7.

[0037] In the above scheme, it is intended to solve the problem that if there is an inclined track on the track 1, the inspection body 2 is damaged and cannot be moved at the inclined track of the track 1, and the inspection body 2 loses connection with the track 1 and is lowered, the inspection body 2 itself is unstable and cannot be accurately reset; the second electric push rod 701 is connected to the control panel signal, and the force of the swing of the weight block 702 on the sliding support plate 703 is greater than the maximum elastic force of the spring connected to the sliding support plate 703. The spring connected to the sliding support plate 703 is only used to restore its central position in the left and right directions on the connecting frame 6, and the support shell 7 The lower part is provided with two left and right rotating shafts, and four U-shaped grooves are provided on the connecting frame 6. The sliding support plate 703 and the U-shaped grooves corresponding to the connecting frame 6 form a square frame. The rotating shaft of the supporting shell 7 is located in two adjacent square frames on the same side of the connecting frame 6. The side length of the square frame on the connecting frame 6 is equal to the diameter of the rotating shaft of the supporting shell 7. By moving the sliding support plate 703, the rotating axis of the connecting frame 6 and the supporting shell 7 is switched, so that the device can stably lower the inspection body 2 at different inclined positions of the track 1. The stability of the inspection body 2 during movement and the accuracy of resetting of the device are improved.

[0038] Working process: when the inspection body 2 enters the uphill position of the track 1, the weight block 702 swings to the left, and the weight block 702 pushes the sliding support plate 703 to move to the left, and the sliding support plate 703 compresses the connected spring. At this time, the two square frames on the left side of the connecting frame 6 become U-shaped grooves, and the two square frames on the right side of the connecting frame 6 rotate and cooperate with the left rotating shaft of the supporting shell 7. If the inspection body 2 moves to the uphill position of the track 1 and is damaged, the inspection body 2 cannot continue to move, and the above-mentioned operation of releasing the limit and swinging the rotating block 4 is repeated. Then the maintenance personnel first start the second electric push rod 701 and the right motor 201, and the right motor 201 rotates to release the first and second pull ropes 9 and 10 on the right side, and the telescopic end of the second electric push rod 701 gradually extends, and the connecting frame 6, the inspection body 2 and the fixed plate 5 rotate with the left rotating shaft of the supporting shell 7, and the connecting frame 6 swings clockwise (from front to back), and the right rotating shaft of the supporting shell 7 moves out from the two U-shaped frames on the right side of the connecting frame 6. When the fixed plate 5 and the connecting frame 6 After rotating to the horizontal state, the control panel turns off the second electric push rod 701 and starts the left motor 201, and repeats the operations of lowering, repairing and resetting the above-mentioned inspection body 2. When the relative positions of the fixing plate 5 and the connecting frame 6 are restored, the control panel turns off the left motor 201 and starts the second electric push rod 701. The telescopic end of the second electric push rod 701 contracts and drives the connecting frame 6 to swing upward and reset. When the connecting frame 6 is swung and reset, the right side rotating shaft of the support shell 7 enters the two U-shaped frames on the right side of the connecting frame 6. The control panel turns off the second electric push rod 701 and the right side motor 201, and then repeats the above-mentioned reset operation of the sliding plate 304, so that the connection between the track 1 and the inspection body 2 is restored to the initial state. The inspection body 2 continues to move along the track 1 to monitor the highway tunnel. When the inspection body 2 moves to the horizontal position of the track 1, the weight block 702 swings and resets, and at the same time, the sliding support plate 703 moves and resets under the elastic force of the connected spring. At this point, all parts are restored to their initial positions.
