Bent cap support transportation construction method and transportation device

Abstract

The invention relates to a cover beam support transportation construction method and a transportation device. The transport support is installed on the two transport vehicles, the loading position is determined through the theoretical center-of-gravity positions of the transport support and the bent cap support, and the two transport vehicles are controlled to carry the transport support to synchronously drive into the loading position. And when the pressure of the jacking capping beam supports of the two transport vehicles reaches the preset pressure, the current bearing pressure value is obtained in real time so as to judge the bearing balance of the two transport vehicles. And when the bearing pressure difference value of the two transport vehicles exceeds the preset difference value, the adjusted position of the transport support driven by the two transport vehicles corresponds to the actual gravity center of the bent cap support. Due to the fact that the loads of the two transport vehicles are more uniform, local excessive abrasion of the transport vehicles caused by uneven loads in traditional transport is avoided, the problem that the transport vehicles are not synchronous due to unbalanced loads is solved, and safety and stability in the transport process are improved.

Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a method and device for transporting and constructing a cap beam support. Background Art

[0002] In bridge construction, the construction of the main pier cap beam typically involves erecting a cap beam support on the pier before pouring concrete. Because cap beam construction requires high-altitude work, the support must possess large structural specifications to meet load-bearing requirements. However, these large supports have low reuse rates, and the installation and removal processes are cumbersome, requiring significant labor and time, resulting in low construction efficiency.

[0003] In order to improve the safety, quality and progress of cap beam construction, existing technologies such as patent CN205205687U and patent application CN118756582A propose to set a sliding device or moving wheels at the bottom of the cap beam bracket to realize the overall movement of the bracket after the construction is completed; the running mechanism disclosed in patent CN221778310U lifts the cap beam bracket by a mobile trolley and transports it to the next work station to realize recycling, which improves the construction efficiency and the reuse rate of the bracket to a certain extent, but only considers the adjustment of the installation position of the cap beam bracket.

[0004] However, due to the heavy weight and height of the cap beam support, it is very easy to experience instability such as shaking and tilting during transportation, and even cause safety accidents. Therefore, the stability of the transportation process is particularly important. However, the existing technology has not proposed an effective solution for transportation stability and cannot guarantee the reliability of the cap beam support during transportation. Therefore, a transportation and construction plan is urgently needed to improve the stability and safety of the cap beam support during transportation to meet the actual needs of efficient and reliable bridge construction. Summary of the Invention

[0005] Based on this, it is necessary to provide a cap beam support transportation construction method and transportation device that can improve the stability and safety during transportation to address the above problems.

[0008] In one embodiment, step S520 includes: controlling the transport vehicle to lift the cap beam support according to a preset load weight, and then removing the connection structure between the cap beam support and the pier and the abutment.

[0009] In one embodiment, step S540: controlling two transport vehicles to move synchronously along a preset trajectory to the next designed bridge position includes: S541: The transport vehicle stops after driving to the set distance from the designed bridge position and measures the relative position data between the cap beam support and the bridge pier, as well as the height difference data between the cap beam support and the abutment. S542: Start the transport vehicle and adjust the position of the cap beam support according to the relative position data and the height difference data, so that the cap beam support is aligned between the two bridge piers at the designed bridge location. After the bottom of the cap beam support is higher than the top surface of the pedestal by more than a first preset distance, control the transport vehicle to travel along the corresponding trajectory to the installation position at the designed bridge location. S543: Controlling the transport vehicle to lower the height of the cap beam support so that the distance between the bottom of the cap beam support and the top surface of the pier reaches a second preset distance, and measuring the position data between the cap beam support, the pier, and the bridge pier; S544: Control the movement of the transport vehicle according to the measured position data, so that the cap beam support moves to a preset position relative to the abutment and the pier; S545: Control the hydraulic jack of the transport vehicle to descend until the bottom of the cap beam support is fully supported on the pedestal.

[0010] In one embodiment, step S545 includes: S5451: After releasing the top connection mechanism between the transport support and the cap beam support, control the transport vehicle's hydraulic jack to descend until the bottom of the cap beam support is fully supported on the pedestal. Release the top connection mechanism to prevent the connection from affecting the fall of the cap beam support. S5452: Remove the bottom connection mechanism between the transport bracket and the cap beam bracket, and continue to lower the stroke of the transport vehicle's hydraulic jack until the transport bracket is completely separated from the cap beam bracket; S5453: When the clearance height is unobstructed, control the transport vehicle carrying the transport bracket to move synchronously and move out of the current designed bridge position.

[0011] In one embodiment, step S300: obtaining the current bearing pressure values ​​of the two transport vehicles includes: S310: Obtain the current bearing pressure value of each support point of the two transport vehicles and , and the total load of the two transport vehicles is 、 ; Step S400 includes: S410: Obtain the load ratio of the two transport vehicles based on the total load of the two transport vehicles , determine whether the load ratio exceeds a preset threshold; S420: If yes, then the current horizontal adjustment spacing is obtained according to the current bearing pressure value. ; Where k is the dynamic correction factor, the initial value k=1, and L is the lateral distance between the two transport vehicles; S430: Adjust the spacing according to the current horizontal direction Generate lateral movement instructions to control the synchronous lateral movement of two transport vehicles , so that the load ratio between the total loads of the two transport vehicles reaches a preset threshold.

[0012] In one embodiment, step S400 further includes: S440: Obtain the current coordinates of each support point of the two transport vehicles, and obtain the actual longitudinal center of gravity coordinates of the cap beam support and the transport support: ;in and are the longitudinal coordinates of each support point of the two transport vehicles, and the weight of the cap beam support is W g The total weight of the cap beam support and the transport support is W total ; S450: Based on the longitudinal coordinates of the joint load center of the two transport vehicles Calculate the longitudinal center of gravity offset: ; Among them, if , then the transport vehicle moves backwards, if , the transport vehicle moves forward; S460: According to the longitudinal center of gravity offset , synchronously control the longitudinal movement of the two transport vehicles so that the actual longitudinal center of gravity coordinates of the transport bracket and the cap beam bracket are aligned with the longitudinal coordinates of the joint load-bearing center of the two transport vehicles.

[0013] In one embodiment, step S400 further includes: S470: According to the longitudinal center of gravity offset and the current horizontal adjustment spacing Generate the synthetic motion of the two transport vehicles executed synchronously, and the direction of the synthetic motion is ; S480: According to the synthetic movement direction and and Control the synchronous movement of two transport vehicles.

[0014] In one embodiment, step S430 further includes: if the current horizontal adjustment spacing When the load is greater than the maximum adjustable threshold, the two transport vehicles are triggered to adjust and move to the maximum adjustment position, and the transverse adjustment component on the transport bracket is controlled to adjust the relative position between the transport vehicle and the transport bracket so that the load ratio between the total loads of the two transport vehicles reaches the preset threshold.

[0015] In one embodiment, step S460 further includes: if the current horizontal adjustment spacing When it is greater than the maximum adjustable threshold, the two transport vehicles are triggered to drive the transport bracket to adjust and move to the maximum adjustment position, and then the transport vehicles are controlled to move forward and backward relative to the transport bracket to adjust the relative position between the transport vehicle and the transport bracket, so that the overall actual center of gravity of the transport bracket and the cap beam bracket is consistent with the longitudinal coordinate of the joint load-bearing center of the two transport vehicles.

[0016] Compared with the existing technology, the above-mentioned cap beam support transportation and construction method has at least the following beneficial effects: During construction, the transport bracket is first installed on two transport vehicles. First, the theoretical center of gravity of the transport bracket and the cap beam bracket is calculated, and the loading position is determined based on this. The two transport vehicles carrying the transport bracket are controlled to enter the loading position synchronously. Due to problems such as processing errors and structural layout accuracy of the transport bracket and the cap beam bracket, the theoretical center of gravity of the cap beam bracket will be inconsistent with the actual center of gravity. Therefore, in order to address the possible deviation between the theoretical center of gravity and the actual center of gravity, a trial jacking pressure detection mechanism is introduced. When the jacking pressure of the two transport vehicles reaches the preset pressure, the current load-bearing pressure value is obtained in real time to judge the load balance of the two transport vehicles. When the load-bearing pressure difference between the two transport vehicles exceeds the preset difference, the jacking is released and the position of the transport vehicle is adjusted so that the adjusted position of the transport bracket driven by the two transport vehicles corresponds to the actual center of gravity of the cap beam bracket, effectively eliminating the center of gravity offset problem caused by processing errors, insufficient structural layout accuracy and other factors, and ensuring that the actual center of gravity of the cap beam bracket is consistent with the center of gravity of the transport device.

[0017] Because the loads on the two transport vehicles are more evenly distributed, excessive wear on the transport vehicles caused by uneven loads during traditional transportation is avoided, extending the service life of the equipment and reducing maintenance costs. This also eliminates the problem of transport vehicle asynchrony caused by unbalanced loads, effectively avoiding the risks of swaying and tilting of the cap beam bracket due to uneven loads during transportation, significantly improving the safety and stability of the transportation process.

[0018] A transport device is used in the cap beam support transport construction method in any of the above-mentioned embodiments, wherein the transport device includes a transport support and two transport vehicles, wherein the transport support includes a connecting support and two groups of support column assemblies arranged relatively spaced apart, wherein the connecting support is located between the two groups of support column assemblies and connects the two groups of support column assemblies; the two transport vehicles are respectively arranged at the bottom of the two support column assemblies and synchronously support the transport support.

DETAILED DESCRIPTION

[0035] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0036] See Figure 1 The transport device 10 in one embodiment of the present application can at least realize the overall transportation of the cap beam support 20, thereby facilitating the reuse of the cap beam support 20. Specifically, the transport device 10 includes a transport support 102 and at least two transport vehicles 104. The transport support 102 includes a connecting bracket 110 and two sets of support column assemblies 120 that are relatively spaced apart. The connecting bracket 110 is located between the two sets of support column assemblies 120 and connects the two sets of support column assemblies 120. The two transport vehicles 104 are respectively arranged at the bottom of the two support column assemblies 120 and synchronously support the transport support 102.

[0037] like Figure 2 As shown, specifically, the support column assembly 120 includes a plurality of spaced support columns 122. The number of support columns 122 is consistent with the number of oblique tube columns 202 of the cap beam support 20, and the spacing between two adjacent support columns 122 is greater than the spacing between two adjacent oblique tube columns 202. Specifically, the transport support 102 also includes two bottom support frames 130, each of which corresponds to the bottom of a support column assembly 120. The bottom of the bottom support frame 130 is formed with a support space 136 for accommodating the transport vehicle 104.

[0038] See Figures 3 to 5In one embodiment, the transport bracket 102 also includes a lateral movement adjustment component 300, which includes a support pad 310 and two lateral movement force sources 320. The two lateral movement force sources 320 are respectively arranged on opposite sides of the support pad 310. The support pad 310 is used to be placed on the support surface of the transport vehicle 104 so that the two lateral movement force sources 320 are respectively located on opposite sides of the transport vehicle 104. Each lateral movement force source 320 can extend toward the inner wall of the relative support space 136 and abut against the inner wall of the support space 136.

[0039] Specifically, the support pad 310 is a rubber pad. By setting the support pad 310 as a rubber pad, the friction between the transport bracket 102 and the transport vehicle 104 can be increased, and the pressure fluctuation caused by the small vibration of the transport vehicle 104 can be absorbed. In addition, the rubber deformation can adaptively compensate for the flatness error of the support surface.

[0040] Furthermore, the lateral adjustment assembly 300 also includes two connecting plates 330 and two thrust plates 340. The two connecting plates 330 are respectively connected to opposite sides of the support pad 310. Each lateral force source 320 is correspondingly mounted on a connecting plate 330. Each thrust plate 340 is rotatably disposed on an end of the lateral force source 320 away from the connecting plate 330. The thrust plates 340 can abut against the inner wall of the support space 136. The connecting plates 330 are rigid plates. The thrust plates 340 can be rigid plates or rubber plates.

[0041] In this embodiment, the lateral movement adjustment assembly 300 is an integral modular component that can be removed from the transport vehicle 104. When in use, the support pad 310 only needs to be placed on the transport vehicle 104 and the two lateral movement force sources 320 are located on opposite sides of the transport vehicle 104. Furthermore, since the support pad 310 is a rubber pad, it is easy to store and install on the transport vehicle 104.

[0042] See also Figure 6In one embodiment, the transport bracket 102 further includes connecting ropes 400. The connecting ropes 400 are arranged in multiple groups, each group containing multiple ropes. Each support column assembly 120 can be secured to the transport vehicle 104 via two of the connecting ropes 400. One end of each connecting rope 400 is secured to the support column assembly 120, while the other ends of each connecting rope 400 are mounted on the transport vehicle 104, one on each side of the two transverse force sources 320. The length of each connecting rope 400 is adjustable. In this embodiment, the connecting ropes 400 can be manual hoists, or alternatively, electric hoists, which are mounted on the transport vehicle 104 to control the rope length. In this embodiment, each support column 122 is equipped with four 5-ton manual hoists, two of which are connected to opposite sides of the transport vehicle 104. Lugs are welded to the support columns 122 of the transport bracket 102 for mounting the connecting ropes 400.

[0043] like Figure 1 and Figure 7 As shown, in one embodiment, the transport bracket 102 further includes a bottom connection mechanism 200. There are at least four bottom connection mechanisms 200, which are divided into two groups. The two bottom connection mechanisms 200 in each group are respectively connected to the outermost support column 122 and the inclined tube column 202. The length of each bottom connection mechanism 200 is adjustable. Specifically, the bottom connection mechanism 200 is located near the bottom of the support column assembly 120.

[0044] In one embodiment, the bottom connection mechanism 200 includes a first screw rod 210, a second screw rod 220, and an adjusting screw sleeve 230. The adjusting screw sleeve 230 has internal threads with opposite spiral directions formed at both ends. The first screw rod 210 and the second screw rod 220 are respectively threadedly connected to the ends of the adjusting screw sleeve 230. The end of the first screw rod 210 away from the adjusting screw sleeve 230 is rotatably connected to the support column assembly 120, and the end of the second screw rod 220 away from the adjusting screw sleeve 230 is detachably connected to the oblique tube column 202 of the cap beam support 20. By rotating the adjusting screw sleeve 230, the length of the bottom connection mechanism 200 can be steplessly adjusted within a certain range. Furthermore, the bottom connecting mechanism 200 also includes a first locking nut 240 and a second locking nut 250. The first locking nut 240 is threaded on the first screw 210 and can be locked on the adjusting screw sleeve 230. The second locking nut 250 is threaded on the second screw 220 and can be locked on the adjusting screw sleeve 230.

[0045] In one embodiment, opposite ends of the bottom connection mechanism 200 are rotatably connected to the support column assembly 120 and the inclined tube column 202 of the cap beam support 20. Specifically, the bottom connection mechanism 200 can rotate vertically relative to the cap beam support 20, that is, the rotation axis is set in the horizontal direction.

[0046] See Figure 1 and Figures 8 to 10 In one embodiment, the transport bracket 102 further includes a support beam 140, which is disposed on top of the support column assembly 120. The transport bracket 102 further includes a top connection mechanism 500, which is disposed on the support beam 140. The top connection mechanism 500 includes a transverse limiting unit 510 and a longitudinal limiting unit 520. The transverse limiting unit 510 is capable of transverse movement and abutting against the side of the support bracket 204 of the cap beam bracket 20, while the longitudinal limiting unit 520 is capable of longitudinal movement and abutting against the end surface of the support bracket 204 of the cap beam bracket 20. In this embodiment, the transverse movement direction is the direction from one support column assembly 120 toward the other support column assembly 120, and the longitudinal movement direction is the forward direction of the transport vehicle 104, which is also a direction intersecting the transverse movement direction. During use, the lower portion of the cap beam support 20 is rigidly connected to the transport support 102 via the bottom connection mechanism 200, and the upper portion of the cap beam support 20 is limited in the transverse and longitudinal directions relative to the transport support 102 via the transverse limiting unit 510 and the longitudinal limiting unit 520, respectively. Furthermore, since both the transverse limiting unit 510 and the longitudinal limiting unit 520 are movable and adjustable, they can be easily adjusted according to the actual position of the cap beam support 20 and the transport support 102, and can also be easily separated from the transport support 102 after transportation is completed.

[0047] In this embodiment, each supporting beam 140 is provided with two top connection mechanisms 500, which are arranged opposite to each other in the longitudinal direction and are respectively located on opposite sides of the supporting corbel 204. The top connection mechanisms 500 on the two supporting beams 140 are symmetrically arranged.

[0048] Specifically, the transverse limiting unit 510 includes a limiting power source 511, a transverse member 512, a first elastic member 513, and a first limiting plate 514. The first limiting plate 514 is disposed on the side of the transverse member 512 facing the support corbel 204 of the cap beam support 20 via the first elastic member 513. The first elastic member 513 is used to provide an elastic force for the first limiting plate 514 toward the support corbel 204. The limiting power source 511 is used to drive the transverse member 512 to move along the transverse direction toward or away from the support corbel 204. The longitudinal limiting unit 520 includes a second limiting plate 521, a second elastic member 522, and a mounting member 523. The mounting member 523 is mounted on the supporting crossbeam 140. The second limiting plate 521 is disposed on the side of the mounting member 523 facing the support corbel 204 via the second elastic member 522. The second elastic member 522 is capable of providing an elastic force for the second limiting plate 521 toward the support corbel 204. By providing the first elastic member 513 and the second elastic member 522 , the first limiting plate 514 and the second limiting plate 521 can be elastically abutted against the cap beam support 20 .

[0049] In this embodiment, the limiting power source 511 is a component such as a hydraulic rod, an electric push rod, etc. that can drive the transverse member 512 to move.

[0050] In this embodiment, the longitudinal limiting unit 520 further includes a longitudinal moving member 524, and the second limiting plate 521 is disposed on the longitudinal moving member 524 via a second elastic member 522. The top connection mechanism 500 further includes a linkage unit 530, which is disposed on the mounting member 523. The transverse moving member 512 and the longitudinal moving member 524 are connected via the linkage unit 530. When the transverse moving member 512 moves toward the support bracket 204, the linkage unit 530 can drive the longitudinal moving member 524 to move along the longitudinal direction toward the support bracket 204. The provision of the linkage unit 530 enables synchronous movement of the first limiting plate 514 and the second limiting plate 521.

[0051] In other embodiments, a longitudinal moving force source may be provided, and the linkage unit 530 may be omitted, so that the longitudinal moving force source directly drives the longitudinal moving member 524 to move.

[0052] like Figure 6 and Figure 11 As shown, in one embodiment, the transporter 104 is a self-propelled modular transporter 104. Depending on the actual working conditions, different modules can be selected and combined to form transporters 104 of various tonnages and shapes to meet the needs of various working conditions. For example, in this embodiment, the self-propelled modular transporter 104 can be raised and lowered. The electronic steering of the self-propelled modular transporter 104 is computer-controlled, and each bogie can be independently steered and rotated in any direction, sideways, or on-site. The wheel bogies are steered by an electro-hydraulic multi-directional steering system, which provides longitudinal, lateral, and center-slew drive steering programs.

[0053] In one embodiment, the transport vehicle 104 is equipped with multiple pressure sensors for detecting the support pressure of the transport support 102 and the cap beam support 20 at various support points. This allows for subsequent determination of support stability based on the detected pressure data, and allows for adjustment of the relative position of the transport vehicle 104 based on the detected pressure data to ensure stability during transportation. For example, the pressure sensors are located opposite the bottom support member 134.

[0054] See Figure 12 The cap beam support transportation construction method in one embodiment of the present application can at least improve the safety and stability of the transportation process. Specifically, the cap beam support transportation construction method includes: like Figure 1 As shown, a support bracket 204 is welded at the design elevation of the cap beam support 20 to ensure that the support brackets 204 on the two inclined tube columns 202 of the cap beam support 20 are arranged relative to each other and at the same level. Since the transport bracket 102 is needed to support the installation of the cap beam support 20 during subsequent transportation, a structure for connecting to the transport bracket 102 needs to be installed on the cap beam support 20.

[0055] Specifically, the entire structure of the support bracket 204 is pre-welded and spliced ​​on the ground, then hoisted as a whole to the design elevation of the cap beam support 20 and welded and fixed. Furthermore, a support plate is welded at the design elevation of the cap beam support 20, and the support bracket 204 is hoisted as a whole onto the support plate and then welded and fixed. Since the cap beam support 20 has relatively arranged inclined tube columns 202, the support brackets 204 on the two sets of relatively arranged inclined tube columns 202 should be located at the same elevation to ensure synchronous support in the later stage.

[0056] like Figures 3 to 6 As shown, S100: installing the transport bracket 102 onto two transport vehicles that are spaced apart.

[0057] Specifically, 3D modeling software is used to calculate the center of gravity of the transport bracket 102. Two transport vehicles 104 are then driven to the bottom of the transport bracket 102 at a predetermined distance. The positions of the transport vehicles 104 are adjusted so that the fixed areas at the center of the vehicles are precisely aligned with the center of gravity of the transport bracket 102. The combined centers of the two transport vehicles 104 are aligned horizontally and vertically at the center of gravity of the transport bracket 102. Once the transport vehicles 104 are in place, the transport bracket 102 is secured to the two transport vehicles 104.

[0058] Furthermore, lugs are welded to the transport bracket 102, and one end of a connecting rope 400 is connected to the transport bracket 102, while the other end is tightened and secured to the frame of the transport vehicle 104. Each transport vehicle 104 is equipped with at least three connecting ropes 400, each of which is spaced apart around the corresponding transport vehicle 104. The connecting ropes 400 limit the longitudinal and lateral displacement of the transport vehicle 104 and the transport bracket 102.

[0059] Furthermore, the two transverse moving force sources 320 are controlled to extend synchronously until the two push plates 340 respectively abut against the bottom support frame 130 of the transport bracket 102 .

[0060] S200: According to the loading position corresponding to the theoretical center of gravity position of the cap beam support 20, the two transport vehicles 104 are controlled to carry the transport support 102 to move into the loading position synchronously.

[0061] like Figure 1 and Figure 2 As shown, specifically, after the transport vehicle 104 has installed the transport bracket 102, it drives into the loading position directly below the cap beam bracket 20, and adjusts the fixed area of ​​the joint center of the two transport vehicles 104 bodies to align with the theoretical center of gravity of the cap beam bracket 20, so as to ensure that the placement of the loaded transport bracket 102 and the cap beam bracket 20 conforms to the load-bearing characteristics of the transport vehicle 104 platform, so that the load-bearing capacity of the transport vehicle 104 is maximized and the use state of the transport vehicle 104 is optimal. Furthermore, based on the theoretical center of gravity of the cap beam bracket 20 and the positions of the two transport vehicles 104, the support point position directly below the center of the cap beam bracket 20 and corresponding to the supporting bracket 204 is staked out to facilitate the transport vehicle 104 to align more quickly with the theoretical center of gravity of the cap beam bracket 20.

[0062] S300: Control the two transport vehicles 104 to synchronously lift the transport bracket 102 to support the cap beam bracket 20, so that when the lifting pressure of the two transport vehicles 104 reaches a preset pressure, obtain the current bearing pressure value of the two transport vehicles 104; wherein, the preset pressure is less than the weight of the cap beam bracket 20.

[0063] Specifically, the transport vehicle 104 is controlled to lift the frame using its hydraulic lifting system to lift the cap beam support 20 as a whole. The preset pressure can be 5%-15% of the weight of the cap beam support 20. In this embodiment, the preset pressure can be 5%-15% of the combined weight of the cap beam support 20 and the transport support 102, preferably 10% of the combined weight. The support pressure gauge readings at various locations on the transport vehicle 104 are then checked.

[0064] Furthermore, step S300: obtaining the current bearing pressure values ​​of the two transport vehicles 104 includes: S310: Obtain the current bearing pressure value of each support point of the two transport vehicles 104 and , the total load of the two transport vehicles 104 is 、 In this embodiment, the two transport vehicles 104 are defined as vehicle A and vehicle B, and the total load of vehicle A is , the total load of car B is .

[0065] S400: If the difference between the current bearing pressure values ​​of the two transport vehicles 104 is greater than or equal to the preset difference, the two transport vehicles 104 are controlled to release the jacking, and the positions of the two transport vehicles 104 are adjusted according to the current bearing pressure value, and then step S300 is executed in a loop until the current bearing pressure of the two transport vehicles 104 is less than the preset difference.

[0066] In one embodiment, step S400 includes: S410: Obtain the load ratio of the two transport vehicles 104 based on the total load of the two transport vehicles 104 , determining whether the load ratio exceeds a preset threshold. Specifically, the preset threshold range is between 0.95 and 1.05. If the load ratio is greater than 1, it means that the load of vehicle A is greater than that of vehicle B. Otherwise, it means that the load of vehicle A is less than that of vehicle B.

[0067] S420: If yes, then the current horizontal adjustment spacing is obtained according to the current bearing pressure value. Wherein, k is the dynamic correction factor, the initial value k=1, and L is the lateral distance between the two transport vehicles 104. A Greater than P B , the left car has a large pressure, the center of gravity is biased to the left, and needs to move to the left. B Greater than P A , the pressure on the right car is greater, so the center of gravity is biased to the right and needs to move to the right.

[0068] For example, set k=1, if P A =550kN, P B =450kN, L=3m, then , adjust car A and car B to move synchronously towards the direction of car A, reduce the support arm of car B, and increase the support arm of car A.

[0069] In this embodiment, the two transport vehicles 104 are moved and the new pressure difference is measured. , compared with the previous test results, the adjustment effect ratio is ,in, If α is less than the preset constant, for example, α is less than 0.5 or less than 0.3, it proves that the adjustment effect is insufficient. Therefore, in the next adjustment, the dynamic correction factor is increased, for example, k 新=1.2k; if the sign of ΔP′ is reversed, it means overshoot, then the dynamic correction factor should be adjusted to reduce, for example, k 新 =0.8k; otherwise the dynamic correction factor k remains unchanged.

[0070] S430: Adjust the spacing according to the current horizontal direction Generate lateral movement instructions to control the two transport vehicles 104 to move horizontally synchronously , so that the load ratio between the total loads of the two transport vehicles 104 reaches a preset threshold.

[0071] Specifically, the two transport vehicles 104 are controlled to move laterally synchronously. Then, continue to lift the cap beam support 20 and obtain the pressure value of each supporting point of the two transport vehicles 104, and repeat steps S410 and S420 until the load ratio between the total loads of the two transport vehicles 104 reaches a preset threshold.

[0072] Furthermore, in order to ensure that the two transport vehicles 104 run synchronously, a PID controller may be used to dynamically adjust the speeds of the two transport vehicles 104 to improve the synchronization of the movement of the two transport vehicles 104 .

[0073] In one embodiment, the two transport vehicles 104 are controlled to move laterally synchronously. After that, continue to lift the cap beam support 20 and obtain the pressure value of each support point of the two transport vehicles 104, and recalculate the pressure value of each support point on the two transport vehicles 104. , according to the current The value of controls the transverse adjustment component on the transport bracket 102 to adjust the relative position between the transport vehicle 104 and the transport bracket 102.

[0074] Specifically, step S430 further includes: if the current horizontal adjustment spacing When the load ratio of the two transport vehicles 104 is greater than the maximum adjustable threshold, the two transport vehicles 104 are triggered to adjust to the maximum adjustment position, and the lateral adjustment component 300 on the transport support 102 is controlled to adjust the relative position between the transport vehicle 104 and the transport support 102, so that the load ratio between the total load of the two transport vehicles 104 reaches the preset threshold. Make adjustments. Due to the limitation of the installation position of the top connection mechanism 500, and the limitation of the position of the support beam 140 and the support bracket 204, there is an adjustment distance limitation between the cap beam bracket 20 and the transport bracket 102 to avoid affecting the stable support of the support beam 140 on the support bracket 204. The reason why the transport vehicle 104 is adjusted first to drive the transport bracket 102 to adjust as a whole relative to the cap beam bracket 20 is to avoid the need to add the step of unlocking the transport vehicle 104 and the transport bracket 102 due to the adjustment of the transport bracket 102, and to add the step of fixing the installation between the transport vehicle 104 and the transport bracket 102 after the adjustment. This application will only adjust the relative position relationship between the transport bracket 102 and the transport vehicle 104 through the transverse adjustment component 300 when the adjustment of the transport bracket 102 relative to the cap beam bracket 20 fails to meet the adjustment support pressure requirement.

[0075] In one embodiment, step S400 further includes: S440: Obtain the current coordinates of each support point of the two transport vehicles 104, and obtain the actual longitudinal center of gravity coordinates of the cap beam support 20 and the transport support 102: ;in and are the longitudinal coordinates of the supporting points of the two transport vehicles 104, and the weight of the cap beam support 20 is W g The total weight W of the cap beam support 20 and the transport support 102 is total ; S450: Based on the longitudinal coordinates of the joint carrying centers of the two transport vehicles 104 Calculate the longitudinal center of gravity offset: ; Among them, if , then the transport vehicle 104 moves backward, if , the transport vehicle 104 moves forward; S460: Synchronously control the longitudinal movement of the two transport vehicles 104 according to the longitudinal center of gravity offset so that the actual longitudinal center of gravity coordinates of the transport bracket 102 and the cap beam bracket 20 are aligned with the longitudinal coordinates of the joint load-bearing center of the two transport vehicles 104.

[0076] In one embodiment, after step S460, the following steps are further included: obtaining the current coordinates of each support point of the two transport vehicles 104 again, obtaining the current actual longitudinal center of gravity coordinates of the cap beam support 20 and the transport support 102, and evaluating the longitudinal coordinates of the joint bearing center of the two transport vehicles 104. If the difference is within the preset range, the adjustment is completed. If the difference exceeds the preset range, step S450 and step S460 are re-executed.

[0077] In another embodiment, step S460 includes: S461: Set the initial moving step length to , control the two transport vehicles 104 to drive the transport bracket 102 to move synchronously with the initial moving step length ;in, It can be 0.1-1; S462: Re-acquire the pressure data of all support points and recalculate the actual longitudinal center of gravity coordinates of the cap beam support 20 and the transport support 102: ; S463: According to the new , get the rate of change of center of gravity ; Then according to the rate of change of center of gravity , recalculate the longitudinal center of gravity offset ; S464: Control the two transport vehicles 104 to drive the transport bracket 102 to move synchronously by the longitudinal center of gravity offset Repeat steps S462 to S464 until Within the accuracy threshold.

[0078] In one embodiment, step S460 further includes: if the current horizontal adjustment spacing When it is greater than the maximum adjustable threshold, the two transport vehicles 104 are triggered to drive the transport bracket 102 to adjust and move to the maximum adjustment position, and the transport vehicle 104 is controlled to move forward and backward relative to the transport bracket 102 to adjust the relative position between the transport vehicle 104 and the transport bracket 102, so as to make the overall actual center of gravity of the transport bracket 102 and the cap beam bracket 20 consistent with the longitudinal coordinate of the joint load-bearing center of the two transport vehicles 104.

[0079] In one embodiment, step S400 further includes: S470: According to the longitudinal center of gravity offset and the current horizontal adjustment spacing Generate a synthetic motion of the two transport vehicles 104 that is executed synchronously, and the direction of the synthetic motion is ; S480: According to the synthetic movement direction and and The two transport vehicles 104 are controlled to move synchronously.

[0080] In one embodiment, the two transport vehicles 104 can be controlled to move horizontally in one movement adjustment. Then adjust vertically .

[0081] In another embodiment, after the two transport vehicles 104 are controlled to move laterally, the cap beam support 20 is lifted and the longitudinal movement is obtained according to the newly detected pressure data. After the adjustment is completed, lift the cap beam support 20 again and get the pressure data according to the new test. , and repeat this cycle until both the longitudinal coordinate and the lateral load meet the accuracy requirements.

[0082] like Figure 11 As shown, in one embodiment, the transport vehicle 104 can move in different directions by adjusting the direction of the moving wheels. Specifically, the transport vehicle 104 is a self-propelled module transport vehicle 104.

[0083] In the above method, load data can be directly obtained in real time through the pressure sensor, without the need for additional coordinate calculation, and the response speed is fast. When making lateral adjustments, it does not rely on the precise measurement of geometric coordinates, but is based on the principle of force balance, and is insensitive to interference such as mechanical installation errors. Even if the cap beam support 20 has a complex shape or uneven load distribution, as long as the loads of the two vehicles are balanced, the lateral center of gravity can be aligned. The goal of the longitudinal displacement adjustment is to align the center of gravity of the transport support 102 and the cap beam support 20 with the load-bearing center of the two vehicles in the longitudinal direction. The longitudinal adjustment is based on static precise positioning of geometric coordinates to ensure position alignment. The lateral adjustment is based on dynamic and rapid adjustment of force balance to ensure load balance. The longitudinal and lateral adjustments are independently controlled by coordinates and loads respectively, avoiding the coupling effect during two-dimensional linkage adjustment, such as lateral movement may cause longitudinal position changes; and there is no need to design a complex multivariable coupling controller, the algorithm is simple to implement, and easy to implement in engineering. This decoupling control strategy reduces system complexity and improves adjustment efficiency, and is suitable for the synchronous support and precise positioning scenarios of large equipment such as this application.

[0084] In one embodiment, the method for transporting and constructing the cap beam support 20 further includes: S510: detachably connect the transport bracket 102 to the cap beam bracket 20.

[0085] like Figure 1 and Figure 7 Specifically, after adjusting the length of the bottom connecting mechanism 200 according to the distance between the cap beam support 20 and the transport support 102, the bottom connecting mechanism 200 is connected to the cap beam support 20. Furthermore, the adjusting screw sleeve 230 of the bottom connecting mechanism 200 is screwed, and then the second screw rod 220 is connected to the oblique tube column 202 of the cap beam support 20. The adjusting screw sleeve 230 is screwed again until the first screw rod 210 and the second screw rod 220 are respectively pressed against the support column 122 and the oblique tube column 202.

[0086] like Figure 1 and Figure 8 As shown, specifically, the lateral limiting unit 510 and the longitudinal limiting unit 520 are controlled to elastically abut against the supporting corbel 204 from the side wall and end surface of the supporting corbel 204 respectively, so as to limit the lateral and longitudinal relative displacement.

[0087] S520: dismantling the connection structure between the cap beam support 20 and the bridge pier and the abutment; S530: Control the transport vehicle 104 to lift the cap beam support 20 away from the bearing surface, and continue to obtain the current bearing pressure values ​​of the two transport vehicles 104 to perform a load test; S540: If the current bearing pressure values ​​of the two transport vehicles 104 are less than the preset difference, the two transport vehicles 104 are controlled to run synchronously along the preset trajectory to the next designed bridge position.

[0088] After the positions of the transport vehicle 104, the transport support 102 and the cap beam support 20 are adjusted, the transport support 102 is connected to the cap beam support 20 to ensure stability during transportation. At the same time, the connection between the cap beam support 20 and the pier and the platform support is removed to facilitate the overall transportation of the cap beam support 20. Before transportation, the cap beam support 20 is lifted off the platform by trial jacking, and the current bearing pressure values ​​of the two transport vehicles 104 are obtained for test load and evaluation. If it is within the preset difference range, the operation is started. If it is not within the preset difference range, the cap beam support 20 needs to be placed back on the platform surface, and the position of the transport vehicle 104 needs to be readjusted to reduce problems caused by unbalanced load during transportation.

[0089] Specifically, step S520 includes controlling the transport vehicle 104 to lift the cap beam support 20 at a preset load weight, and then removing the connection structure between the cap beam support 20 and the piers and abutments. For example, the cap beam support 20 may be supported at 10% of its weight to facilitate removal of the connection structure between the cap beam support 20, the piers, and the abutments.

[0090] In one embodiment, step S540: controlling the two transport vehicles 104 to move synchronously along a preset trajectory to the next designed bridge position includes: S541: The transport vehicle 104 stops after traveling to a set distance from the designed bridge position, and measures the relative position data between the cap beam support 20 and the bridge pier, and the height difference data between the cap beam support 20 and the pier; S542: Start the transport vehicle 104, and adjust the position of the cap beam support 20 according to the relative position data and the height difference data, so that the cap beam support 20 is located between the two bridge piers at the designed bridge position, and after the bottom of the cap beam support 20 is higher than the top surface of the pedestal to a first preset distance, control the transport vehicle 104 to travel along the corresponding track to the installation position at the designed bridge position; specifically, the first preset distance can be 20 cm.

[0091] S543: Control the transport vehicle 104 to lower the height of the cap beam support 20 so that the distance between the bottom of the cap beam support 20 and the top surface of the pedestal reaches a second preset distance, and measure the position data between the cap beam support 20 and the pedestal and the pier; specifically, the second preset distance is smaller than the first preset distance. In this embodiment, the second preset distance can be 5 cm.

[0092] S544: Control the transport vehicle 104 to move according to the measured position data, so that the cap beam support 20 moves to a preset position relative to the abutment and the pier; S545: Control the hydraulic jack of the transport vehicle 104 to descend until the bottom of the cap beam support 20 is fully supported on the base.

[0093] Specifically, slowly lower the stroke of the hydraulic jack of the transport vehicle 104, observe the gap between the bottom pad beam of the cap beam support 20 and the pedestal, and when the bottom of the bottom pad beam is supported on the pedestal and bears the force, the lowering work of the transport vehicle 104 onboard jack should be stopped.

[0094] In one embodiment, step S545 includes: S5451: After releasing the top connection mechanism between the transport support 102 and the cap beam support 20, control the hydraulic jack of the transport vehicle 104 to descend until the bottom of the cap beam support 20 is fully supported on the pier. Release the top connection mechanism to prevent the connection from affecting the fall of the cap beam support 20. Specifically, after the cap beam support 20 is in place, recheck the accuracy of the position of the cap beam support 20. After ensuring that it is correct, use the connection structure to connect the cap beam support 20 to the pier and the pier.

[0095] S5452: Remove the bottom connection mechanism between the transport bracket 102 and the cap beam bracket 20, and continue to lower the stroke of the hydraulic jack of the transport vehicle 104 until the transport bracket 102 is completely separated from the cap beam bracket 20.

[0096] S5453: When the clearance height is unobstructed, the transport vehicle 104 is controlled to carry the transport bracket 102 and move synchronously out of the current designed bridge position.

[0097] During construction, the transport bracket 102 is first installed on two transport vehicles 104. First, the theoretical center of gravity of the transport bracket 102 and the cap beam bracket 20 is calculated, and the loading position is determined based on this. The two transport vehicles 104 are controlled to carry the transport bracket 102 into the loading position synchronously. Due to problems such as processing errors and structural layout accuracy of the transport bracket 102 and the cap beam bracket 20, the theoretical center of gravity and the actual center of gravity of the cap beam bracket 20 may be inconsistent. Therefore, in order to address the possible deviation between the theoretical center of gravity and the actual center of gravity, a trial jacking pressure detection mechanism is introduced. When the jacking pressure of the two transport vehicles 104 reaches the preset pressure, the current load-bearing pressure value is obtained in real time to determine the load balance of the two transport vehicles 104. When the difference in bearing pressure between the two transport vehicles 104 exceeds the preset difference, the jacking is released and the position of the transport vehicle 104 is adjusted so that the adjusted position of the transport bracket 102 driven by the two transport vehicles 104 corresponds to the actual center of gravity of the cap beam bracket 20, effectively eliminating the center of gravity offset problem caused by processing errors, insufficient structural layout accuracy and other factors, and ensuring that the actual center of gravity of the cap beam bracket 20 is consistent with the center of gravity of the transport device 10.

[0098] Because the loads on the two transport vehicles 104 are more evenly distributed, excessive wear on the transport vehicles 104 caused by uneven loads during traditional transportation is avoided, extending the equipment's service life and reducing maintenance costs. Furthermore, the problem of asynchrony between the transport vehicles 104 due to unbalanced loads is eliminated, effectively avoiding the risk of swaying and tilting of the cap beam support 20 due to uneven loads during transportation, significantly improving the safety and stability of the transportation process.
