Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a bridge pier correction and resetting device and a correction and resetting method. Background Art

[0002] Due to the influence of bridge engineering design, construction, environmental factors and human factors, the problem of bridge pier position deviation often occurs. The main reason for this is that the load not carried on the bridge is transmitted to the bridge pier through the construction, which in turn affects the pier and causes bending moment. After long-term influence, the deviation of the pier will become more and more serious. If the tensile stress exceeds a certain limit, it will cause obvious cracks.

[0003] The Chinese patent application number 2016210341897 discloses a partial deviation correction device for a bridge, including a vertical jack for lifting the bridge, a support part for sliding and resetting the bridge, a working platform located on the offset side of the bridge, a hydraulic oil pump installed on the working platform, a horizontal jack for providing lateral thrust for the offset bridge, and a transmission part for transmitting the lateral thrust, wherein the transmission part includes a top block, an oblique support connected to the top block and in contact with the bridge, a vertical support connected to the oblique support, a counterweight tray connected to the vertical support, and a counterweight block for fixing the vertical support. By setting up a working platform on the horizontal ground and using the horizontal jack and the transmission part to achieve partial deviation correction of the laterally offset bridge, the difficulty of the operation is greatly reduced and the damage to the bridge pier is reduced. However, during the correction process, the above-mentioned correction device can only apply local force to correct a certain fixed point of the pier. For very high piers, it is difficult to correct the pier columns at different heights. At the same time, the above-mentioned device can only correct the pier columns from a single direction. If the pier columns are to be corrected horizontally and vertically, the overall structure needs to be adjusted and moved, which results in a large workload and complicated operation.

[0008] The correcting assembly includes a correcting cylinder, which is fixedly arranged in the center of a mounting plate or a fixing frame.

[0014] The present invention also provides a correction and resetting method for a bridge pier correction and resetting device, comprising the following steps:

[0015] Step 1: Lift the beam using the jacks on the top of the support frames at both ends;

[0016] Step 2: Climbing along the bridge pier, the climbing motor drives the climbing gear plates at both ends to rotate, driving the fixed frame and the deviation correction mechanism to start climbing upward along the bridge pier at a uniform speed;

[0017] Step 3: Lateral correction and resetting: Use the detection assembly on the mounting plate to detect the lateral inclination of the bridge pier.

[0020] Beneficial effects of the present invention:

[0021] (1) By setting up a climbing component and a correcting component, the climbing motor will drive the transmission gear rotating rods at both ends through the driving gear, and the transmission gear will drive the climbing tooth plate to rotate through the rotating shaft. The climbing tooth plate and the climbing groove are engaged with each other to drive the fixing frame and the correcting mechanism to climb upward from the bottom of the pier. During the climbing process, since a set of correcting mechanisms are respectively provided on the mounting plate and the fixing frame, the two sets of detection components will respectively perform lateral and longitudinal inclination detection on the pier. When inclination is detected at a certain height of the pier, the corresponding correcting cylinder will push the push plate, and the push plate will apply lateral or longitudinal loads to the pier to make it move until it is reset, thereby realizing the lateral and longitudinal correction and reset process for any height of the pier.

[0022] (2) By setting up a detection component, when the climbing component drives the fixed frame to climb upward along the support frame, the pressure plate is pushed by the pressure spring and pushes the slide bar outward. At the same time, the roller will be against the side wall of the pier and roll upward along the side wall of the pier during the climbing process. During this process, the roller will always be against the side wall of the bridge. Its slight horizontal movement will be fed back to the horizontal displacement of the metal pad through the detection rod. At the same time, the photoelectric sensor can monitor the displacement change distance of the metal pad in real time. Once the distance exceeds the threshold set in advance, it can be determined that the pier has tilted at this height, and a control signal is sent to cooperate with the correction component to correct and reset the pier. In this way, the tilt detection of the pier at different heights can be realized through the change of the photoelectric signal, which greatly improves the detection accuracy.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 , Figure 2 and Figure 4 As shown, a device for correcting and resetting a bridge pier comprises a beam body 1 and a pier 2, wherein the beam body 1 is mounted on the upper end of the pier 2, support frames 3 are symmetrically arranged on both sides of the pier 2, the bottom ends of the support frames 3 are fixedly installed on the ground through fixed bases 301, jacks 302 are fixedly arranged on the tops of the support frames 3, the output ends of the jacks 302 are in contact with the bottom of the beam body 1, a group of fixing frames 4 are symmetrically arranged on the support frames 3, climbing components 5 are symmetrically arranged between the fixing frames 4, each group of climbing components 5 cooperates with the corresponding support frames 3, mounting plates 6 are symmetrically arranged in the support frames 3, the mounting plates 6 and the fixing frames 4 form a rectangle and enclose the pier 2 in the rectangle, and correction mechanisms are arranged on the mounting plates 6 and the fixing frames 4, the correction mechanisms comprise correction components 7 and detection components 8, and the correction components 7 and detection components 8 are relatively arranged on both sides of the pier 2.

[0035] like Figure 5 and Figure 6As shown, the climbing component 5 includes a shell 501, in which a pair of driving gears 504 and a pair of transmission gears 505 are rotatably installed in the inner cavity of the shell 501, the driving gears 504 are meshed with each other, and the transmission gears 505 are located at both ends and meshed with the corresponding driving gears 504, and a climbing motor 509 is fixedly installed on the outer wall of the shell 501, and the output end of the climbing motor 509 is connected with one of the driving gears 504, and a rotating shaft 506 is sleeved in the transmission gear 505, one end of the rotating shaft 506 passes through the shell 501 and is fixedly connected with a shaft sleeve 507, and climbing tooth plates 508 are evenly arranged on the outside of the shaft sleeve 507 at equal intervals, and climbing grooves 303 are evenly spaced on both sides of the support frame 3, and the climbing tooth plates 508 are engaged with the climbing grooves 303, and the climbing motor 509 drives the climbing tooth plates 508 at both ends to rotate to drive the fixing frame 4 and the correction mechanism to climb vertically along the pier 2.

[0036] like Figure 4 As shown, the correcting assembly 7 includes a correcting cylinder 701, which is fixedly arranged at the center of the mounting plate 6 or the fixing frame 4. The output end of the correcting cylinder 701 is connected to a push plate 702 and faces the pier 2. Both ends of the push plate 702 are fixedly connected to guide rods 703. The guide rods 703 slide through the corresponding mounting plate 6 or the fixing frame 4. The end of the guide rod 703 is fixedly connected to a baffle 704. A return spring 705 is arranged on the outside of the guide rod 703, and the return spring 705 is fixedly connected to the baffle 704.

[0037] Specifically, by setting up the climbing component 5, the climbing motor 509 will drive the transmission gear 505 rotating rod at both ends through the driving gear 504, and the transmission gear 505 will drive the climbing tooth plate 508 to rotate through the rotating shaft 506. The climbing tooth plate 508 and the climbing groove 303 are engaged with each other, so as to drive the fixing frame 4 and the correction mechanism to climb upward from the bottom end of the pier 2. During the climbing process, since a group of correction mechanisms are respectively provided on the mounting plate 6 and the fixing frame 4, the two groups of detection components 8 will respectively perform lateral and longitudinal inclination detection on the pier 2. When the inclination is detected at a certain height of the pier 2, the corresponding correction cylinder 701 will push the push plate 702, and the push plate 702 will be used to apply a lateral or longitudinal load to the pier 2, so that it moves until it is reset, thereby realizing the lateral and longitudinal correction and reset process for any height of the pier 2.

[0038] like Figure 7 and Figure 8As shown, the detection component 8 includes a cylinder 801, which is fixedly installed at the center of the corresponding mounting plate 6 or the fixing frame 4. A rod sleeve 802 is extended from the front end of the cylinder 801, and a slide rod 803 is coaxially slidably installed in the rod sleeve 802. A rotating bracket 804 is fixedly connected to the front end of the slide rod 803. A roller 805 is rotatably installed in the rotating bracket 804, and the roller 805 rests on the side wall of the pier 2. The rear end of the slide rod 803 extends into the cylinder 801 and is connected to a pressure plate 806. A retaining ring 807 is circumferentially arranged in the cylinder 801, and a pressure spring 808 is arranged between the pressure plate 806 and the retaining ring 807.

[0039] Furthermore, a detection rod 809 is fixedly provided in the center of the pressure plate 806 , the end of the detection rod 809 passes through the retaining ring 807 and is fixedly provided with a metal pad 810 , a photoelectric sensor 811 is fixedly provided on the inner wall of the cylinder 801 , and the metal pad 810 is arranged opposite to the photoelectric sensor 811 .

[0040] Specifically, by setting up the detection component 8, when the climbing component 5 drives the fixed frame 4 to climb upward along the support frame 3, the pressure plate 806 is pushed by the pressure spring 808, and will push the slide bar 803 outward. At the same time, the roller 805 will be against the side wall of the pier 2 and roll upward along the side wall of the pier 2 during the climbing process. During this process, the roller 805 will always be against the side wall of the bridge, and its slight movement in the horizontal direction will be fed back to the horizontal displacement of the metal pad 810 through the detection rod 809. At the same time, the photoelectric sensor 811 can monitor the displacement change distance of the metal pad 810 in real time. Once the distance exceeds the threshold set in advance, it can be determined that the pier 2 has tilted at this height, and a control signal is sent to cooperate with the correction component 7 to correct and reset the pier 2, so that the tilt detection of the pier 2 at different heights can be realized through the change of the photoelectric signal, which greatly improves the detection accuracy.

[0041] like Figure 7 As shown, a limit block 8031 ​​is provided on the outer side of the slide rod 803 along the length direction, and a limit groove 8021 corresponding to the limit block 8031 ​​is provided on the inner wall of the rod sleeve 802, and the limit block 8031 ​​is adapted to be slidably installed in the limit groove 8021.

[0042] Specifically, in order to ensure that the roller 805 can always roll vertically along the correct path on the side wall of the pier 2, by utilizing the sliding cooperation between the limit block 8031 ​​and the limit groove 8021, not only can the slide bar 803 slide horizontally normally in the rod sleeve 802, but the limit block 8031 ​​will also impose a rotation constraint on the slide bar 803, so that it can only slide, thereby avoiding unnecessary rotation of the slide bar 803, and further ensuring that the rotating bracket 804 and the roller 805 can always maintain the correct rolling path.

[0043] like Figure 4 As shown, the fixing frame 4 is respectively provided with a first slot 401 and a second slot 402 , and wing plates 502 are extended from both ends of the shell 501 . The wing plates 502 are fixedly connected to the fixing frame 4 through the first slot 401 , and both ends of the mounting plate 6 are fixedly connected to the fixing frame 4 through the second slot 402 .

[0044] Specifically, the shell 501 and the connecting parts of the mounting plate 6 and the fixing frame 4 all use locking bolts, and the connection is reliable and stable. At the same time, when it is necessary to change the correction direction of the correction component 7 and the detection direction of the detection component 8, the locking bolts can be removed to change the position of the relative fixing frame 4 or mounting plate 6.

[0045] like Figure 3 and Figure 5 As shown, a limit guide rail 304 is vertically arranged on the inner wall of the support frame 3 along the height direction, and a limit sleeve 503 is fixedly arranged on the side wall of the shell 501 , and the limit sleeve 503 is slidably matched with the limit guide rail 304 .

[0046] Specifically, during the climbing process, the limiting sliding sleeve 503 will always keep sliding in the limiting guide rail 304 to prevent the fixing frame 4 from shaking during the climbing process, thereby improving the stability of the fixing frame 4 during the climbing process.

[0047] The working principle of the present invention is as follows: Figure 1-Figure 8 As shown, when in use, first support and fix the support frame 3 on both sides of the pier 2, and use the jacks 302 on the top of the support frames 3 at both ends to lift the beam body 1, so that the pier 2 is no longer subjected to the pressure of the beam body 1, which is convenient for correction. The climbing motor 509 is started, and the transmission gears 505 at both ends are driven to rotate through the driving gear 504. The transmission gear 505 will drive the climbing tooth plate 508 to rotate through the rotating shaft 506. The climbing tooth plate 508 and the climbing groove 303 are engaged, which can drive the fixing frame 4 and the correction mechanism to climb upward from the bottom of the pier 2. During the climbing process, the pressure plate 806 is pushed by the pressure spring 808, which will push the slide bar 803 outward. At the same time, the roller 805 will be against the side wall of the pier 2 and roll upward along the side wall of the pier 2 during the climbing process. During this process, the roller 805 will always be against the bridge. On the side wall, any slight movement in the horizontal direction will be fed back to the horizontal displacement of the metal pad 810 through the detection rod 809. At the same time, the photoelectric sensor 811 can monitor the displacement change distance of the metal pad 810 in real time. Once the distance exceeds the threshold set in advance, it can be determined that the pier 2 has tilted at this height, and a control signal is sent to cooperate with the correction component 7 to correct the pier 2 and reset it. The correction cylinder 701 will push the push plate 702, and the push plate 702 will be used to apply a lateral or longitudinal load to the pier 2 to make it move until it is reset, thereby realizing the lateral and longitudinal correction and reset process of the pier 2 at any height.

[0048] The present invention also provides a correction and resetting method for a bridge pier correction and resetting device, comprising the following steps:

[0049] Step 1: Lift the beam 1 by using the jacks 302 on the top of the support frames 3 at both ends;

[0050] Step 2: Climbing along the bridge pier 2, the climbing motor 509 drives the climbing gear plates 508 at both ends to rotate, driving the fixing frame 4 and the deviation correction mechanism to start climbing upward along the bridge pier 2 at a uniform speed;

[0051] Step 3: Lateral correction and resetting: the detection assembly 8 on the mounting plate 6 is used to detect the lateral inclination of the pier 2. When the inclination is detected, the correction cylinder 701 pushes the push plate 702 to apply a lateral load to the pier 2, so that the pier 2 moves laterally and resets;

[0052] Step 4: Longitudinal correction and resetting. The detection assembly 8 on the fixed frame 4 is used to detect the longitudinal inclination of the pier 2. When the inclination is detected, the push plate 702 is pushed by the correction cylinder 701 to apply a longitudinal load to the pier 2, so that the pier 2 moves longitudinally and resets.

[0053] Step 5: After the beam body 1 is reset and the pier 2 is corrected and reset, the beam body 1 is lowered and re-mounted on the reset pier 2 using the jacks 302 at both ends, and finally the support frame 3 is removed.

[0054] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.

A method for correcting and resetting a bridge pier according to any one of claims 1 to 6, characterized in that: The following steps are involved: Step 1: Lifting the beam body (1) by using the jacks (302) on the top of the support frames (3) at both ends to lift the beam body (1); Step 2: Climbing along the bridge pier (2), the climbing motor (509) drives the climbing gear plates (508) at both ends to rotate, driving the fixing frame (4) and the deviation correction mechanism to start climbing upward along the bridge pier (2) at a uniform speed; Step 3: Lateral correction and resetting, using the detection assembly (8) on the mounting plate (6) to detect the lateral inclination of the bridge pier (2), and when inclination is detected, the correction cylinder (701) pushes the push plate (702) to apply a lateral load to the bridge pier (2), so that the bridge pier (2) moves laterally and resets; Step 4: longitudinal correction and resetting, using the detection assembly (8) on the fixing frame (4) to detect the longitudinal inclination of the bridge pier (2). When the inclination is detected, the correction cylinder (701) pushes the push plate (702) to apply a longitudinal load to the bridge pier (2), so that the bridge pier (2) moves longitudinally and is reset. Step 5: After the beam body (1) is reset and the pier (2) is corrected and reset, the beam body (1) is lowered using the jacks (302) at both ends and re-mounted on the reset pier (2), and finally the support frame (3) is removed.
