[0025] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0026] In this application, all component models and structures not explicitly specified are existing technologies known to those skilled in the art. Those skilled in the art can make settings according to actual needs, and no specific limitations are made in the embodiments of this application.

[0027] Specifically, such as Figs. 1-3 As shown, this embodiment of the invention provides a steel truss girder floating towing and sliding construction device, including a floating vessel 1. Multiple support frames 5 for supporting steel trusses are evenly arranged on the deck of the floating vessel 1. Several floating airbags 4 are evenly arranged on the bottom surface of the floating vessel 1. The gas in the floating airbags 4 is controlled by an air pump 6 that can be inflated and inhaled. The air pump 6 is located on the deck. A water level line 3 is also provided on the side of the floating vessel 1.

[0028] This invention supports the steel truss beam by setting up a temporary support frame on the floating vessel 1. The steel truss beam is moved horizontally from one end of the river to the other by waterway. While moving along the waterway, the size of the floating airbag 4 is adjusted according to the floating height of the floating vessel 1 to regulate the buoyancy of the floating vessel 1. This allows the steel truss beam to be transported smoothly in the waterway, reducing construction costs and saving construction time.

[0029] During construction, workers operate the floating vessel 1 and use the support frame 5 on the floating vessel 1 to support the steel truss beam. As the floating vessel 1 moves across the river, the steel truss beam moves simultaneously to the opposite bank. When the floating vessel 1 reaches the opposite bank, the steel truss beam will be fully connected to the bridge pier on the opposite bank, completing the smooth transportation of the steel truss beam.

[0030] When transporting, the workers drive the floating boat 1, and according to the height of the water level line 3, it is judged whether the buoyancy of the floating boat 1 on the water surface needs to be increased or reduced, so that the height of the steel truss can be ensured to remain unchanged during transportation.

[0031] When starting transportation, the floating air bag 4 is opened in part, and the distribution of the opened floating air bag 4 is uniform. When increasing or reducing, it is necessary to ensure that the distribution of the opened floating air bag 4 after increasing or reducing is uniform, so as to ensure the stability of the floating boat 1, and the stability of the steel truss transportation.

[0032] In the present application, a plurality of water quantity sensors 8 are uniformly arranged on the water level line 3, and each floating air bag 4 is connected with the air pump 6 through an electromagnetic valve.

[0033] The present application uses a processor to adjust the buoyancy of the floating boat 1, so that the floating boat 1 remains on the same water level line 3, so that the steel truss on the floating boat 1 is at a fixed height.

[0034] The specific working mode is: the processor can obtain the current state of the floating boat 1, including the inclination state of the floating boat 1, according to the water quantity detected by the water quantity sensor 8 and the position corresponding to the water quantity sensor 8. Then according to the state of the floating boat 1, it is judged whether the buoyancy should be reduced or increased, and which place the buoyancy should be reduced or increased, so as to determine the floating air bag 4 that needs to be adjusted, and then according to the control source of the floating air bag 4 that needs to be adjusted, that is, the electromagnetic valve and the air pump 6 corresponding to each floating air bag 4, the floating air bag 4 is subjected to air extraction or inflation treatment, so that the processor adjusts the buoyancy of the floating boat 1.

[0035] In addition, in order to save costs, the number of water quantity sensors 8 is twice the number of the side of the floating boat 1, and one water quantity sensor 8 is arranged at each end of each side of the floating boat 1. Through the values and positions of the left and right two water quantity sensors 8, the current state of the floating boat 1 can be clearly obtained.

[0036] In the present application, the values detected by each water quantity sensor 8 of the same side of the floating boat 1 are all within the set range, which indicates that the current state of the floating boat 1 is normal and does not need to be adjusted. Of course, the set range of the values detected by the water quantity sensors 8 of each side of the floating boat 1 is the same.

[0037] In the present application, in order to further adjust the state of the floating boat 1 through data, the bottom of the support frame 5 is connected with the surface of the floating boat 1 through a pressure sensor 7; the pressure sensor 7 is signal connected with the processor, and the pressure sensor 7 is electrically connected with the power supply.

[0038] The present application determines the required buoyancy by receiving the pressure given by the steel truss, and then controls the electromagnetic valve and the air pump 6 to make the floating air bag 4 to obtain the corresponding buoyancy through the processor according to the required buoyancy, so as to control the state of the floating boat 1.

[0039] The working process is that the processor receives the data of the pressure sensor 7, and converts the data of the pressure sensor 7 into the size of the pressure, and combines the size of the comprehensive force, which is originally set, and the size of the comprehensive force is calculated according to the gravity of the steel truss and the gravity of the support frame 5. Thus, in order to determine the size of the comprehensive force in the range of the required size, it is necessary to adjust the size of the buoyancy, so that we can obtain a range of the size of the buoyancy. According to the range, the electromagnetic valve and the corresponding air pump are uniformly controlled to make the floating air bag 4 uniformly provide the buoyancy to the floating boat 1, so as to control and adjust the state of the floating boat 1.

[0040] In the present application, since the floating air bag 4 needs to provide uniform buoyancy, the bottom surface of the floating boat 1 is sequentially provided with a plurality of air bag lines 9 from inside to outside, the innermost air bag line 9 is a straight line, and the remaining air bag lines 9 are annular; the air bag line 9 is provided with the floating air bag 4.

[0041] The annular air bag line 9 can effectively uniformly distribute the floating air bag 4, so that the floating air bag 4 is uniformly distributed at the bottom of the floating boat 1, so that the floating boat 1 has uniform buoyancy, thereby ensuring the stable transportation of the steel truss.

[0042] Each of the air bag lines 9 is uniformly provided with a plurality of floating air bags 4.

[0043] In the present application, in order to better support the steel truss and ensure that the bottom surface of the steel truss is not damaged during transportation, the support frame 5 comprises a support column 5-1, and the top of the support column 5-1 is provided with a supporting pad for supporting the steel truss.

[0044] In order to reinforce the support column 5-1 and make the support frame 5 stable and firm, the support frame 5 further comprises a plurality of stabilizing plates 5-2 and a plurality of fixing rods 5-3, the stabilizing plates 5-2 are uniformly arranged along the circumference of the top of the support column 5-1, the top of the stabilizing plate 5-2 is connected with the supporting pad, and the fixing rods 5-3 are uniformly arranged along the circumference of the bottom of the support column 5-1, and the bottom of the fixing rod 5-3 is fixed on the surface of the floating boat 1.

[0045] In the application, in order to quickly and effectively determine the butt joint stability of the steel truss girder and the bridge piers on the opposite banks of the river, the floating ship 1 is respectively provided with a limiting ring 2 on the left and right sides in the moving direction. The application can make the steel truss girder smoothly butt joint the bridge piers on the two sides by limiting the movement track of the floating ship 1, so that the contact stability of the steel truss girder and the bridge piers can be quickly and effectively determined during the construction.

[0046] During the construction, the positionally opposite positioning rods are arranged near the bridge piers at both ends of the river, the positioning rods are fixed, and the corresponding positioning rods are connected through chains, generally, thick iron chains or titanium alloy chains, chains of materials with high hardness commonly used in engineering, or connecting rods can be used, the chains or connecting rods pass through the limiting ring 2, so that the floating ship 1 moves along the length direction of the chains or connecting rods during the driving, and the floating ship 1 is limited, so that the effect of quickly and effectively determining the contact stability of the steel truss girder and the bridge piers is achieved.

[0047] The above is only the preferred embodiment of the application, and does not limit the application, and any simple modification, change and equivalent structure change of the above embodiment according to the technical essence of the application are still within the protection scope of the technical scheme of the application.
