[0032] See also Figures 1 to 4 As shown, according to the first aspect of an embodiment of the present application, a bracket is provided for use in a monitoring system, the bracket comprising a frame unit and a fastener 2; the frame unit comprises a first end and a second end, the first end is used to install the monitoring system, and the second end is provided with a through hole; the fastener 2 comprises a block 201 and a stud 202, one end of the stud 202 is connected to the block 201, the block 201 is used to be installed in the existing slide 6 of the subway tunnel segment, and the other end of the stud 202 passes through the through hole at the second end of the frame unit to fix the frame unit with the monitoring system installed on the existing slide 6 of the subway tunnel segment.

[0033] The fastener 2 is placed into the existing chute 6 of the subway tunnel segment through the narrow end of the block 201 of the fastener 2. The stud 202 of the fastener 2 is rotated 90 degrees to rotate the block 201 so that the block 201 is clamped in the existing chute 6 of the subway tunnel segment. Then, the nut on the stud 202 of the fastener 2 is tightened to fix the bracket installed with the monitoring system in the existing chute 6 of the subway tunnel segment. Using the existing chute 6 of the subway tunnel segment as the connection point of the monitoring system avoids the need to install the monitoring system through drilling into the subway tunnel segment, thus ensuring the original load-bearing structure system of the subway tunnel segment and the service life of the subway tunnel segment. There is no safety hazard. The bracket of the present application is easy to install and adjust and can be reused, which greatly saves production costs.

[0034] Among them, the frame unit is generally a right-angle structure to ensure that the monitoring system is horizontal; the frame unit includes a first end and a second end, the first end is used to install the monitoring system, that is, the first end is a support end for installing the monitoring system, and the second end is processed with a through hole, and the stud 202 of the fastener 2 passes through the through hole of the second end. At the same time, the fastener 2 cooperates with the existing slide groove 6 of the subway tunnel segment, and the stud 202 of the fastener 2 extends out of the frame unit and is fastened by a nut, that is, the second end is a connecting end, which is used to fix the frame unit with the monitoring system installed on the existing slide groove 6 of the subway tunnel segment, thereby ensuring the structural strength of the subway tunnel segment.

[0035] Specifically, the monitoring system in this embodiment is a prism, but in other embodiments it can also be used to install a total station, etc.

[0036] The block 201 includes a narrow end and a long end. The length of the narrow end is less than the groove width of the existing slide groove 6 of the subway tunnel segment, and the length of the long end is greater than the groove width of the existing slide groove 6 of the subway tunnel segment. The block 201 is rotated at a preset angle so that the long end of the block 201 is clamped in the existing slide groove 6 of the subway tunnel segment.

[0037] In this embodiment, the preset angle is 90°. That is, the block 201 is placed into the existing chute 6 of the subway tunnel segment via its narrow end, then rotated 90° counterclockwise or clockwise, with its long end engaging the existing chute 6. This allows the block 201 to slide only within the existing chute 6 but not fall out of it. This utilizes the existing chute 6 of the subway tunnel segment and enables installation of the monitoring system without damaging the original structural strength of the subway tunnel segment.

[0038] Specifically, the block 201 may be rectangular, elliptical, or rhombus-shaped. In this embodiment, the block 201 is rhombus-shaped.

[0039] The frame unit includes a support part 1, which includes a connecting plate 101 and a support plate 102. The connecting plate 101 is connected to the support plate 102, and the support plate 102 rotates relative to the connecting plate 101. The support plate 102 is used to install the monitoring system. A first driving member 104 is provided between the connecting plate 101 and the support plate 102. The first driving member 104 extends or shortens to drive the support plate 102 to rotate counterclockwise or clockwise to make the monitoring system horizontal.

[0040] Among them, the connecting plate 101 is connected to the support plate 102, and the support plate 102 rotates relative to the connecting plate 101, that is, a notch is processed on one end surface of the support plate 102 to form two oppositely arranged bosses on the end surface of the support plate 102, one end of the connecting plate 101 is arranged at the notch, and corresponding shaft holes are opened on the boss and the end of the connecting plate 101, and the connecting shaft 103 is inserted into the boss of the support plate 102 and the shaft mounting hole on the connecting plate 101, so that the support plate 102 rotates relative to the connecting plate 101, so that the support part 1 forms an adjustable type; the connecting plate 101 and the support A first driving member 104 is provided between the plates 102. The extension or contraction of the first driving member 104 drives the support plate 102 to rotate counterclockwise or clockwise. That is, when the first driving member 104 is extended, the support plate 102 rotates counterclockwise; when the first driving member 104 is contracted, the support plate 102 rotates clockwise. Since the inner surface of the subway tunnel segment is an arc-shaped surface, fine-tuning is performed by extending or contracting the first driving member 104 to keep the monitoring system level, reduce installation errors, and avoid cumulative errors within the entire monitoring range.

[0041] Specifically, the first driving member 104 is an electric push rod, a hydraulic cylinder, a pneumatic telescopic rod or a manual telescopic rod. In this embodiment, the first driving member 104 is a manual telescopic member, including a threaded barrel and a screw. One end of the threaded barrel is hingedly connected to the connecting plate 101, and the other end of the threaded barrel is threadedly connected to one end of the screw, and the other end of the screw is threadedly connected to the bottom of the support plate 102. The manual telescopic member can be extended or shortened by rotating the screw.

[0042] The frame unit further includes a translation assembly 3 , which is disposed on the support plate 102 of the support portion 1 . A monitoring system is disposed on the translation assembly 3 , and the translation assembly 3 is used to adjust the horizontal position of the monitoring system.

[0043] The monitoring system is installed on the translation assembly 3. Through the setting of the translation assembly 3, the monitoring system can move horizontally relative to the support plate 102, which can achieve fine adjustment of the horizontal position, and is also conducive to reducing installation errors.

[0044] The translation assembly 3 includes a base 301, a guide rod 302, a screw 303 and a frame 304. A threaded hole and a guide hole are respectively provided at the bottom end of the frame 304. Bearing seats are respectively provided at both ends of the screw 303. The screw 303 passes through the threaded hole and is installed on the support part 1 through the bearing seat. Bases 301 are respectively provided at both ends of the guide rod 302. The guide rod 302 passes through the guide hole and is installed on the support part 1 through the base 301. A monitoring system is provided on the top of the frame 304.

[0045] Among them, during installation and arrangement, there is one lead screw 303 and two guide rods 302, which are arranged on both sides of the lead screw 303; at the same time, threaded holes and guide holes are processed at corresponding positions at the bottom end of the frame 304, which respectively cooperate with the lead screw 303 and the guide rod 302. The reason for setting two guide rods 302 is to make the horizontal movement of the frame 304 smoother due to the symmetry of the structure.

[0046] By rotating the lead screw 303 in a first direction, the frame 304 moves toward the side of the connecting plate 101; by rotating the lead screw 303 in a second direction, the frame 304 moves toward the side away from the connecting plate 101; and here, the first direction and the second direction are opposite to each other; by rotating the lead screw 303, the frame 304 is driven to translate in the horizontal direction, thereby achieving fine adjustment of the horizontal position.

[0047] Specifically, the screw 303 can be rotated manually or electrically. When it is rotated electrically, a motor is installed at the end of the screw 303, and the motor drives the screw 303 to rotate.

[0048] The frame unit further includes a height adjustment component 4 , which is disposed on the translation component 3 . A monitoring system is disposed on the top of the height adjustment component 4 , and the height adjustment component 4 is used to adjust the height position of the monitoring system.

[0049] Among them, by installing the height adjustment component 4 on the translation component 3 and then installing the monitoring system on the height adjustment component 4, fine adjustment of the horizontal position and height position of the monitoring system is achieved.

[0050] The height adjustment assembly 4 includes a second driving member 401 and a sliding rod 404. A sliding hole is opened at the end of the frame 304 away from the support plate 102. One end of the sliding rod 404 is at least partially located in the sliding hole. The sliding rod 404 slides relative to the frame 304. The other end of the sliding rod 404 is connected to the connecting rod 403. The second driving member 401 is arranged at the end of the frame 304 close to the support plate 102. The second driving member 401 rotates relative to the frame 304. A monitoring system is provided at the top of the connecting rod 403, and a pulley 402 is provided at the bottom of the connecting rod 403. The pulley 402 is provided on the second driving member 401. The rotation of the second driving member 401 drives the pulley 402 to move along the driving fin on the second driving member 401 to adjust the height of the monitoring system.

[0051] Among them, by rotating the screw 303 in the forward direction, the connecting rod 403 moves toward the side away from the support plate 102 and at the same time moves toward the side of the frame 304 under the cooperation of the slide rod 404 and the slide hole, at this time the monitoring system is raised; by rotating the screw 303 in the reverse direction, the connecting rod 403 moves toward the side close to the support plate 102 and at the same time moves away from the side of the frame 304 under the cooperation of the slide rod 404 and the slide hole, at this time the monitoring system is lowered; the height adjustment is achieved by rotating the screw 303.

[0052] Specifically, the outer circumference of the second driving member 401 is provided with a spiral drive fin with a variable diameter, the diameter of which increases as it approaches the frame 304. A pulley 402 at the bottom end of the connecting rod 403 cooperates with the drive fin on the second driving member 401. In other words, by rotating the second driving member 401, the pulley 402 can move along the drive fin, thereby achieving height adjustment of the monitoring system.

[0053] More specifically, the second driving member 401 can be manually driven or electrically driven. When electrically driven, a motor is installed at the end of the second driving member 401 to drive the second driving member 401 to rotate.

[0054] The frame unit further includes an angle adjustment component, which is disposed at the top end of the connecting rod 403 of the height adjustment component 4 and is used to adjust the rotation angle of the monitoring system.

[0055] Among them, through the setting of the angle adjustment component, the monitoring system can not only adjust the horizontal position and height position, but also realize angle adjustment with the height direction as the rotation center, so that the monitoring system is at the monitoring point.

[0056] The angle adjustment component includes a fixed shaft 503 and a third driving member 501. The fixed shaft 503 is arranged at the top of the connecting rod 403 of the height adjustment component 4. A base plate 504 is arranged on the fixed shaft 503. The base plate 504 rotates relative to the fixed shaft 503. The base plate 504 is at least partially processed with gear teeth along the circumferential direction. The third driving member 501 is arranged at the top of the connecting rod 403 of the height adjustment component 4. The third driving member 501 is provided with a first gear 502. The first gear 502 cooperates with the gear teeth on the base plate 504.

[0057] Among them, the fixed shaft 503 is arranged at the top of the connecting rod 403 of the height adjustment component 4, that is, the fixed shaft 503 is fixed on the connecting rod 403 and is immovable relative to the connecting rod 403. A base plate 504 is provided on the fixed shaft 503, and the base plate 504 rotates relative to the fixed shaft 503, that is, the base plate 504 has rotational freedom relative to the fixed shaft 503, and the base plate 504 is at least partially processed with gear teeth along the circumferential direction, that is, a gear structure is formed. The third driving member 501 is arranged at the top of the connecting rod 403 of the height adjustment component 4. Here, the third driving member 501 is arranged parallel to the fixed shaft 503, and the third driving member 501 is provided with a first gear 502 that meshes with the gear teeth. By rotating the third driving member 501 clockwise or counterclockwise, the first gear 502 can be engaged with the gear teeth on the base plate 504 to realize the rotation of the base plate 504, thereby realizing the angle adjustment of the monitoring system installed on the base plate 504.

[0058] Specifically, in order to avoid interference between the substrate 504 and the first gear 502, the substrate 504 is set to be stepped, and a spacing space is formed between the large diameter end and the first gear 502 to avoid interference. The small diameter end is used to connect with the fixed shaft 503, and gear teeth are machined on part of the outer peripheral surface of the small diameter end to cooperate with the first gear 502.

[0059] Specifically, the third driving member 501 can be rotated manually or electrically. When it is rotated electrically, a motor is installed at the end of the third driving member 501 to drive the third driving member 501 to rotate.

[0060] A more detailed working process is:

[0061] Install the monitoring system on the base plate 504 of the bracket unit; place the narrow end of the fastener 2 into the existing chute 6 of the subway tunnel segment, and rotate the block 201 90° counterclockwise or clockwise through the stud 202 on the fastener 2, so that the long end of the block 201 is stuck in the existing chute 6 of the subway tunnel segment; install the frame unit, so that the stud 202 of the fastener 2 passes through the through hole on the connecting plate 101 of the frame unit, screw the nut on the stud 202 of the fastener 2, and tighten it to fix the frame unit on the existing chute 6 of the subway tunnel segment; the operator manually rotates the first driving member 104 to adjust the monitoring system to a horizontal level, which can be achieved by installing it on the support plate 102 Use a spirit level to determine whether it is horizontal; manually rotate the second drive member 401 to adjust the horizontal and height movement of the monitoring system. If the horizontal position and height position are exactly at the determined position, there is no need to adjust the translation component 3; directly adjust the angle adjustment component, manually rotate the third drive member 501 to drive the base 504 to rotate with the connecting rod 403 as the rotation center, and adjust the rotation angle of the monitoring system to the observation point; if the height position is appropriate after adjustment by the height adjustment component 4, but the horizontal position has deviations, then the horizontal position is adjusted by the translation component 3, which is achieved by rotating the screw 303, and then the angle of the monitoring system is adjusted by the angle adjustment component. By using the above adjustment method, the monitoring system is exactly at the observation point to obtain more accurate monitoring data.

[0062] According to a second aspect of an embodiment of the present application, a monitoring system is provided, comprising any one of the above-mentioned brackets.

[0063] The fastener 2 is placed into the existing chute 6 of the subway tunnel segment through the narrow end of the block 201 of the fastener 2. The stud 202 of the fastener 2 is rotated 90 degrees to rotate the block 201 so that the block 201 is clamped in the existing chute 6 of the subway tunnel segment. Then, the nut on the stud 202 of the fastener 2 is tightened to fix the bracket installed with the monitoring system in the existing chute 6 of the subway tunnel segment. Using the existing chute 6 of the subway tunnel segment as the connection point of the monitoring system avoids the need to install the monitoring system through drilling into the subway tunnel segment, thus ensuring the original load-bearing structure system of the subway tunnel segment and the service life of the subway tunnel segment. There is no safety hazard. The bracket of the present application is easy to install and adjust and can be reused, which greatly saves production costs.

[0064] The monitoring system of this application has the following advantages:
