Description

Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to a tie rod support device and system for a tie rod arch bridge. Background Art

[0002] A tie-arch bridge is a bridge that uses multiple hangers to connect the arch bridge and the bridge deck to maintain the balance of the bridge deck. It is widely used due to its beautiful shape, large span capacity, and strong adaptability to foundation conditions. The tie-arch bridge maintains the bridge deck in a flat state by using multiple hangers to pull the bridge deck. The pull of the hangers on the bridge deck is transmitted to the ground or piers at both ends through the arch bridge. This pull causes both ends of the arch bridge to be subjected to downward and horizontal components of force at the same time. The downward component of force acts directly on the ground or the piers, while the horizontal component of force needs to be offset by using multiple tie rods to connect the two sides of the arch bridge.

[0003] During the construction of a tied arch bridge, the support frame is often manufactured before the tie rods are installed. Manufacturing errors lead to large errors in the elevation of the support frame, and a large number of tie rods will become empty. In addition, during the operation period, external loads will cause the hanger beam to deform, which in turn causes the support frame on the beam to become detached from the tie rods. If the problem of empty support frames is solved by replacing the support frame during the operation period, the height of each tie rod must be accurately measured, and then the tie rod support frame must be manufactured and replaced in a targeted manner.

[0026] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0027] See also Figures 1-6 , Figure 1 This is a schematic diagram of the three-dimensional structure of the tied arch bridge; Figure 2 This is a first three-dimensional structural schematic diagram of a tie rod support device provided by an embodiment of the present utility model installed on a tie rod arch bridge; Figure 3 This is a second three-dimensional structural schematic diagram of the tie rod support device provided by an embodiment of the present utility model installed on a tie rod arch bridge; Figure 4 yes Figure 3 A magnified view of point A in the figure; Figure 5 This is a partial exploded schematic diagram of the structure of a tie rod support device provided by an embodiment of the present utility model installed on a tie rod arch bridge; Figure 6 yes Figure 5The tie rod support device 1 for a tie rod arch bridge of the present invention comprises at least two rows of bearing components and at least two columns of detection components. The at least two rows of bearing components are arranged in an array along the width direction of the arch bridge, and each row of bearing components is arranged in an array along the length direction of the arch bridge with at least two groups of bearing modules 11. The at least two columns of detection components are arranged in an array along the length direction of the arch bridge, and each column of detection components is arranged in an array along the width direction of the arch bridge with at least two groups of detection modules 12. The bearing module 11 comprises a support frame 111 and a concave pad 112. The support frame 111 is arranged in an array. The concave pad 112 is installed on the steel beam 22 on the boom crossbeam, and the concave pad 112 is installed on the support frame 111. The middle position of the concave pad 112 is provided with a recessed portion for supporting the tie rod 21. The concave pad 112 is slidably connected to the support frame 111 to adjust the supporting height of the concave pad 112 to the tie rod 21. The detection module 12 includes a detector 121 and a receiver 122. The detector 121 and the receiver 122 are respectively connected to the steel beam 22 on both sides of the tie rod 21 to detect the height of the tie rod 21 between two adjacent groups of support modules 11.

[0028] At least two groups of bearing modules 11 are arrayed in the length and width directions of the arch bridge to provide support for multiple tie rods 21 under the action of the bearing modules 11, wherein at least two groups of bearing modules 11 located on the same straight line provide support for multiple positions of the same tie rod 21, so that when the manufacturing error of the support frame 111 is large and the tie rod cannot contact the concave pad 112 and the tie rod 21 is empty, the height of the concave pad 112 is adjusted to make the concave pad 112 contact with the tie rod 21, thereby quickly solving the problem of the tie rod 21 being empty. Compared with the method of targeted replacement of each support frame in the prior art, the tie rod support device of the utility model does not need to replace the support frame, saving manpower and material resources, and can also quickly solve the system emptying problem and improve work efficiency.

[0029] Since the bearing module 11 adopts the support frame 111 and the concave pad 112 to provide support for the tie rod 21, after the support frame 111 is installed on the steel beam 22, the concave pad 112 can be installed on the support frame 111 to provide support for the tie rod 21 under the action of the concave pad 112. Since the same tie rod 21 is supported by at least two bearing modules 11, the force-bearing capacity of each part of the tie rod 21 can be improved. After the length of the tie rod 21 is lengthened, the support height of the tie rod 21 can be adjusted under the action of the concave pad 112 by adjusting the height of the concave pad 112 on the support frame 111 to avoid the manufacturing error of the support frame 111 and the phenomenon that the tie rod 21 is elongated, so that the tie rod 21 can remain in a straight state after the height is adjusted to share the horizontal component of the force on the arch bridge, thereby improving the service life of the arch bridge.

[0030] At least two groups of detection modules 12 are arrayed in the length and width directions of the arch bridge to detect the degree of delamination at various locations of the tie rod 21 under the action of the detection modules 12, wherein at least two groups of detection modules 12 located on the same straight line detect multiple positions of the same tie rod 21 to avoid the phenomenon of local delamination caused by manufacturing errors of the support frame 111 and uneven force at different positions of the tie rod 21, which in turn causes the tie rod 21 to be unable to share the horizontal force of the arch bridge and affects the overall force of the arch bridge.

[0031] Since the detection module 12 detects the height of the tie rod 21 by means of a detector 121 and a receiver 122, that is, the detector 121 and the receiver 122 are respectively installed on the steel beam 22 on both sides of the tie rod 21, and the detection module 12 is located between two adjacent groups of load-bearing modules 11, so that the detector 121 sends a detection signal and the receiver 122 receives the information, the receiver 122 analyzes the received signal to determine the height of the tie rod 21 between the two adjacent groups of load-bearing modules 11, so that when the height of the tie rod 21 is detected to be lower than a preset value, an alarm for the tie rod 21 being empty is triggered, so that the operator can determine the position of the tie rod 21 being empty according to the alarm signal and adjust the two adjacent groups of load-bearing modules 11 at the empty position, that is, the concave pads 112 in the two groups of load-bearing modules 11 are adjusted upward to increase the support height of the concave pads 112 on the tie rod 21, so that the tie rod 21 after the height adjustment can remain in a straight state to share the horizontal component of the force on the arch bridge, thereby improving the service life of the arch bridge.

[0032] In the above embodiment, the detector 121 can be any of a laser transmitter and an acoustic wave transmitter, and the receiver 122 can be any of a laser receiver 122 and an acoustic wave receiver 122. After the detector 121 emits a detection signal, the receiver 122 receives it. When the height of the tie rod 21 changes, the tie rod 21 interferes with the detection signal, and the height change of the tie rod 21 can be detected by analyzing the detection signal. For example, the laser transmitter emits multiple laser beams in the vertical direction, which are received by the laser receiver 122. When the height of the tie rod 21 changes, the tie rod 21 blocks some of the laser beams, causing the laser receiver 122 to be unable to receive these portions of the laser beams. The height of the tie rod 21 can be determined by analyzing the received laser beams.

[0033] In the above embodiment, the detection module 12 also includes a pressure sensor arranged on the concave pad 112 to detect the pressure of the concave pad 112. When the pressure is zero, it proves that the tie rod 21 is empty, and at this time it is necessary to increase the height of the concave pad 112 on the support frame. Conversely, when the pressure exceeds the preset value, it proves that the pressure is too high, and at this time it is necessary to lower the height of the concave pad 112 on the support frame.

[0034] When the concave pad 112 is used to support the tie rod 21, the tie rod 21 can be placed in the recessed portion of the concave pad 112 to increase the contact area between the concave pad 112 and the tie rod 21, thereby avoiding excessive wear of the concave pad 112 due to the contact area being too small, and improving the service life of the concave pad 112.

[0035] Compared with the method of replacing the support frame using a huge amount of engineering and a long engineering cycle, the utility model supports multiple positions of the same tie rod 21 through the support module 11, and uses the detection module 12 to detect multiple positions of the same tie rod 21, so that when part of the position of the tie rod 21 is stretched and becomes empty, the detection module 12 detects the extent of the emptying of the tie rod 21, and triggers an alarm when the height value of the tie rod 21 is lower than the preset value, so that the operator can adjust the support module 11 according to the alarm position, so that the concave pad 112 increases the support height of the tie rod 21, so that the tie rod 21 after the height adjustment can remain in a straight state, so that the tie rod 21 can share the horizontal component of the force for the arch bridge, thereby improving the service life of the arch bridge. The adjustment process is simple and the adjustment speed is fast, and it will not affect the city's traffic.

[0036] In an embodiment of the present utility model, the carrying module 11 also includes a shock-absorbing spring 113, sliders are provided on both sides of the concave pad 112, and sliding grooves for the sliders to slide are opened on both sides of the support frame 111. The two ends of the shock-absorbing spring 113 are respectively against the support frame 111 and the concave pad 112.

[0037] By arranging a shock-absorbing spring 113 between the support frame 111 and the concave pad 112, when the concave pad 112 supports the tie rod 21, the concave pad 112 can float up and down under the action of the shock-absorbing spring 113 to adapt to the change in the force on the bridge deck 2. That is, when the load on the bridge deck 2 changes, the force on the tie rod 21 will change. Frequent changes in the force on the tie rod 21 will cause the tie rod 21 to be stretched. Therefore, under the action of the shock-absorbing spring 113, the force on the tie rod 21 can be buffered to reduce the force change on the tie rod 21 and improve the service life of the tie rod 21.

[0038] In an embodiment of the present utility model, the carrying module 11 also includes an adjusting screw 115, a support pad, a reversing gear 116 and an adjusting member. The bottom of the adjusting screw 115 is rotatably connected to the support frame 111 through the reversing gear 116, and the top of the adjusting screw 115 is threadedly connected to the support pad. The adjusting member is located on the side of the support frame 111 and is rotatably connected to the adjusting screw 115 through the reversing gear 116. The two ends of the shock-absorbing spring 113 are respectively abutted against the support pad and the concave pad 112.

[0039] By rotatably connecting the adjusting screw rod 115 with the support frame 111 and threading the supporting pad with the screw rod, the supporting pad is driven to move up and down along the adjusting screw rod 115 under the rotation of the adjusting screw rod 115. By connecting the reversing gear 116 with the adjusting screw rod 115 and connecting the adjusting member with the reversing gear 116, the adjusting member can drive the adjusting screw rod 115 to rotate from the side of the support frame 111. By arranging the shock-absorbing spring 113 between the concave pad 112 and the supporting pad, when the screw rod rotates and drives the supporting pad to rise and fall, the supporting pad drives the concave pad 112 to rise and fall synchronously through the shock-absorbing spring 113, thereby adjusting the support height of the concave pad 112 on the tie rod 21, and under the action of the shock-absorbing spring 113, the force on the tie rod 21 can be buffered, thereby reducing the force change of the tie rod 21 and improving the service life of the tie rod 21.

[0040] In an embodiment of the present utility model, the adjusting member includes any one of a Z-shaped adjusting handle and a driving motor 117. When the adjusting member adopts a Z-shaped adjusting handle, the detection module 12 detects whether the tie rod 21 is empty, and when it is detected that the tie rod 21 is empty, the operator adjusts the supporting modules 11 at both ends of the empty position, and manually rotates the Z-shaped adjusting handle to drive the adjusting screw 115 to rotate, thereby realizing the adjustment of the support height of the concave pad 112, and supporting the empty tie rod 21 to a straightened height, so that the tie rod 21 shares the horizontal component of the force for the arch bridge.

[0041] When the adjusting member adopts the driving motor 117, the detection module 12 detects whether the tie rod 21 is empty. When it is detected that the tie rod 21 is empty, the operator adjusts the supporting modules 11 at both ends of the empty position, and controls the rotation of the driving motor 117 to drive the rotation of the adjusting screw 115, thereby realizing the adjustment of the support height of the concave pad 112, and supporting the empty tie rod 21 to the straightened height, so that the tie rod 21 shares the horizontal component of the force for the arch bridge.

[0042] In another embodiment of the present invention, a first sleeve is provided on the concave pad, and a second sleeve is provided on the load-bearing beam. The first sleeve and the second sleeve are socketed together. A hydraulic hole connected to the second sleeve is opened on the side of the load-bearing beam. The load-bearing module 11 also includes a hydraulic cylinder installed on the load-bearing beam, and the hydraulic cylinder is connected to the hydraulic hole.

[0043] When the detection module 12 detects that the tie rod 21 is emptied, the operator adjusts the support modules 11 at both ends of the emptied position, controls the extension of the hydraulic cylinder to squeeze the oil into the second sleeve and drive the first sleeve to rise, thereby adjusting the support height of the concave pad 112 and supporting the emptied tie rod 21 to a straightened height, so that the tie rod 21 shares the horizontal component of the arch bridge.

[0044] In an embodiment of the present invention, the number of support frames 111 and concave pads 112 is at least two, and connecting flanges are provided on the upper and lower sides of the support frame 111. At least two support frames 111 are stacked and connected through the connecting flanges, and at least two concave pads 112 are respectively slidably connected to the corresponding support frames 111.

[0045] By arranging connecting flanges on the upper and lower sides of the support frame 111, the support frame 111 can be connected to the steel beam 22 at the bottom of the bridge deck 2 through the upper connecting flange to fix the support frame 111 to the bottom of the bridge deck 2. Since there are multiple pull cylinders in the vertical reverse direction, support frames 111 that match the number of tie rods 21 can be used for connection, that is, the top layer support frame 111 is fixedly connected to the bottom of the bridge deck 2 through the upper connecting flange, the middle layer support frame 111 is fixedly connected to the lower connecting flange of the top layer support frame 111 through the upper connecting flange, and the bottom layer support frame 111 is fixedly connected to the lower connecting flange of the top layer support frame 111 through the upper connecting flange. It is fixedly connected to the lower connecting flange of the middle layer support frame 111, so that multiple support frames 111 are stacked and fixed, so that the concave pads 112 corresponding to the top layer provide support for the tie rods 21 of the top layer, the concave pads 112 corresponding to the middle layer provide support for the middle tie rods 21, and the concave pads 112 corresponding to the bottom layer provide support for the tie rods 21 of the bottom layer. Then, when the detection module 12 detects that any tie rod 21 is empty, the operator can adjust the height of the corresponding concave pads 112 to straighten the empty tie rod 21, so that the tie rod 21 shares the horizontal component of the arch bridge, thereby improving the service life of the arch bridge.

[0046] In an embodiment of the present utility model, the tie rod support device 1 also includes a gantry crane assembly 13, the gantry crane assembly 13 includes a first gantry crane 131, a second gantry crane 132 and a sling 133, the first gantry crane 131 includes a first support plate, a first support leg and a connecting rod, the first support leg is fixedly connected to the first support plate to support the first support plate, the connecting rod is fixed to the side of the first support plate, the second gantry crane 132 includes a fixedly connected second support plate and a second support leg, the second support plate is provided with a socket for connecting the connecting rod, the first support leg and the second support leg are both provided with a rolling wheel 134, and the sling 133 is installed on the first gantry crane 131 and the second gantry crane 132 to pull the tie rod 21.

[0047] When replacing the existing support frame, the gantry crane assembly 13 can be used to pull the tie rod 21 to pull the tie rod 21 up to a certain height from the concave pad 112. At this time, the operator can dismantle the existing support frame and install the support frame 111 of the present invention on the boom crossbeam, thereby realizing rapid dismantling of the existing support frame and rapid installation of the support frame 111 of the present invention on the boom crossbeam to prevent the tie rod 21 from being stretched and becoming empty during subsequent use, so that the tie rod 21 can remain in a straight state after the height is adjusted to share the horizontal component of the force on the arch bridge, thereby improving the service life of the arch bridge.

[0048] When pulling the tie rod 21, the first gantry crane 131 and the second gantry crane 132 are moved to the maintenance channel 23 of the bridge deck 2, and the connecting rod is inserted into the socket to assemble the first gantry crane 131 and the second gantry crane 132 into a whole. The sling 133 is extended from the maintenance channel 23 to the bottom of the bridge deck 2, and the sling 133 is locked with the tie rod 21. Then, the tie rod 21 can be pulled up from the existing support frame by pulling the sling 133, so that the operator can replace the existing support frame.

[0049] In an embodiment of the present invention, the gantry crane assembly 13 also includes at least two cranes 135, at least two cranes 135 are installed on the first support plate and / or the second support plate, and the sling 133 is wound on the crane 135, so that the sling 133 is controlled to pull the tie rod 21 under the action of the crane 135, so as to pull the tie rod 21 from the concave pad 112, so as to facilitate the operator to disassemble and replace the existing support frame.

[0050] In order to solve the technical problems in the prior art, the present invention also provides a tie rod 21 adjustment system for a tie rod arch bridge, which is applied to the above-mentioned tie rod support device 1. The tie rod 21 adjustment system includes a bearing mechanism and a detection mechanism. The detection mechanism is configured to detect whether the height of the tie rod 21 is less than a preset value. The bearing mechanism is configured to adjust the support height of the tie rod 21 when the detection mechanism detects that the height of the tie rod 21 is less than the preset value. Compared with the method of replacing the tie rod 21 with a huge amount of engineering and a long engineering cycle, the present invention supports the tie rod 21 through the bearing mechanism and detects the height of the tie rod 21 using the detection mechanism, so that when the detection mechanism detects that the tie rod 21 is empty, the bearing mechanism is controlled to adjust the support height of the tie rod 21, so that the tie rod 21 after the height adjustment can remain in a straight state, so that the tie rod 21 shares the horizontal component of force for the arch bridge, thereby improving the service life of the arch bridge. The adjustment process is simple and the adjustment speed is fast, and it will not affect the traffic in the city.

[0051] See also Figure 7 , Figure 7This is a flowchart of the steps of the tie rod support method provided by the embodiment of the present invention. In order to solve the technical problems in the prior art, the present invention also provides a tie rod support method for a tie rod arch bridge, which is applied to the above-mentioned tie rod support device. The tie rod support method includes the following steps:

[0052] S1: The detection module detects the height of the tie rod in real time and compares the detected height of the tie rod with the preset value;

[0053] S2: When the tie rod height is detected to be greater than a preset value, the detection module is triggered to continue detecting the tie rod height;

[0054] S3: When the detected tie rod height value is less than a preset value, the carrier module is triggered to adjust the support height of the tie rod.

[0055] In the above steps, the detection module detects the height of the tie rod by means of a detector and a receiver, that is, the detector and the receiver are respectively installed on the steel beams on both sides of the tie rod, and the detection module is located between two adjacent groups of bearing modules, so that the detector sends a detection signal and the receiver receives information, and the receiver analyzes the received signal to determine the height of the tie rod between the two adjacent groups of bearing modules, so that when the tie rod height is detected to be lower than the preset value, the tie rod emptying alarm is triggered, so that the operator can determine the position of the tie rod emptying according to the alarm signal, and adjust the two adjacent groups of bearing modules at the emptying position, that is, the concave pads in the two groups of bearing modules are adjusted upwards to raise or lower the support height of the concave pads for the tie rod, so that the tie rod after the height adjustment can remain in a straight state to share the horizontal component of the arch bridge, thereby improving the service life of the arch bridge.

[0056] The detector can be a laser transmitter or an acoustic wave transmitter, and the receiver can be a laser receiver or an acoustic wave receiver. After the detector emits a detection signal, the receiver receives it. When the tie rod height changes, the tie rod interferes with the detection signal, and the height change of the tie rod can be detected by analyzing the detection signal. For example, a laser transmitter emits multiple laser beams in a vertical direction, which are received by a laser receiver. When the tie rod height changes, the tie rod blocks some of the laser beams, preventing the laser receiver from receiving these portions of the laser beams. The tie rod height can be determined by analyzing the received laser beams.

[0057] In the above embodiment, the bearing module provides support for the tie rod in the form of a support frame and a concave pad, so that after the support frame is installed on the steel beam, the concave pad can be installed on the support frame to provide support for the tie rod under the action of the concave pad. Since the same tie rod is supported by at least two bearing modules, the force-bearing capacity of each part of the tie rod can be improved. After the length of the tie rod is stretched, the support height of the tie rod can be adjusted under the action of the concave pad by adjusting the height of the concave pad on the support frame to prevent the tie rod from being stretched and becoming empty. After the height is adjusted, the tie rod can remain in a straight state to share the horizontal component of the force on the arch bridge, thereby improving the service life of the arch bridge.

[0058] When using a concave pad to support the tie rod, the tie rod can be placed in the recessed portion of the concave pad to increase the contact area between the concave pad and the tie rod, avoid excessive wear of the concave pad due to too small a contact area between the two, and increase the service life of the concave pad.

[0059] Compared with the method of replacing the support frame using a huge amount of engineering and a long engineering cycle, the utility model supports multiple positions of the same tie rod through the support module, and uses the detection module to detect multiple positions of the same tie rod, so that when part of the position of the tie rod is stretched and becomes empty, the detection module detects the extent of the tie rod being empty, and triggers an alarm when the height value of the tie rod is lower than the preset value, so that the operator can adjust the support module according to the alarm position, so that the concave pad increases the support height of the tie rod, so that the tie rod can remain in a straight state after the height is adjusted, so that the tie rod can share the horizontal force for the arch bridge, thereby increasing the service life of the arch bridge. The adjustment process is simple and the adjustment speed is fast, and it will not affect the city's traffic.
