[0032] Example 2

[0033] On the basis of Example 1, Figure 1-Figure 2 As shown, the assembly includes two double-jointed I-beams 2, which are symmetrically arranged at the front and rear ends of the upper end of the steel pontoon 1, and the double-jointed I-beam 2 and the steel pontoon 1 are connected by welding.

Two steel pontoons 1 are symmetrically arranged on the left and right sides of the double-jointed I-beams 2 3;

[0035] The safety components include railings and reflective signs, which are arranged around the working area 5;

[0036] The fixed assembly includes two steel casings 6 and two winches 7, which are arranged in a one-to-one correspondence. The two steel casings 6 are arranged on the front and rear sides of one end of the steel pontoon 1 away from each other, and the two winches 7 are arranged on the front and rear parts of the upper end of the steel pontoon 1.

The double-jointed I-beam 2 3 and the steel pontoon 1 are overlapped for a certain length. The railings and reflective signs are used to ensure the safety of construction operators working on and near water. The movable tube of the steel casing 6 is floated up and down and fixed by the connecting rope connected to the winch. After the two steel pontoons 1 are assembled, a steel pontoon platform is formed. After the steel pontoon platform reaches the target construction position, the winch 7 is controlled to work so that the movable tube of the steel casing 6 sinks to the riverbed. Steel wire ropes 9 are set on the front and rear sides of the ends of the steel pontoons 1 that are away from each other, so that the two steel pontoons 1 The four top corners of the assembled steel pontoon platform are provided with steel wire ropes 9. The four steel wire ropes 9 are tightened to fix the steel pontoon platform. After the construction of the lead hole is completed, the movable tube of the steel casing 6 is pulled up by the winch 7, and the pulled steel wire ropes 9 are loosened. The steel pontoon platform is controlled by the steel wire ropes 9 to move to the next target construction position, and then the steel casing 6 is sunk and the steel wire ropes 9 are tightened, making the steel pontoon platform more stable. The steel pontoon platform can be used for the transportation of various materials on both sides. Specifically, the four steel wire ropes 9 can be connected to an electric winch respectively, and the movement of the steel pontoon platform can be automatically controlled by the electric winch, which improves the transportation efficiency and saves the construction period.

[0039] Example 3

[0040] On the basis of Example 2, Figure 1-Figure 3 As shown, the winch 7 includes a working shell 10, the outside of which is fixedly connected to a motor 11, a working chamber is provided inside the working shell 10, a guide opening 26 is provided at the lower end of the working shell 10, the working chamber is communicated with the guide opening 26, and wire pulleys 25 are symmetrically provided on the left and right sides of the guide opening 26. The motor 11 is fixedly connected to the motor shaft 12, which passes through the side end of the working shell 10 into the working chamber and is slidably connected to the winding wheel 22, the winding wheel 22 is connected to the connecting rope 23, and a connecting rope 23 is provided between the wire pulleys 25 on the left and right sides, and the connecting rope 23 is fixedly connected to the movable tube of the steel casing 6;

[0042] The beneficial effects of the above technical solution are:

[0043] When the winch 7 is working, the motor 11 is started, and the motor 11 drives the motor shaft 12 to rotate. The motor shaft 12 drives the winding wheel 22 automatically, and the winding wheel 22 drives the connecting rope 23 to move. The wire pulleys 25 on the left and right sides guide the movement of the connecting rope 23. The connecting rope 23 can drive the movable tube of the steel casing 6 to move. When the motor shaft 12 rotates, the pulley 13 is synchronously driven to rotate. The pulley 13 drives the pulley 2 15 to rotate through the conveyor belt 14. The pulley 2 15 drives the rotating rod 17 to rotate. The rotating rod 17 drives the threaded sleeve 18 to move along the length direction of the rotating rod 17. The threaded sleeve 18 drives the connecting block 21 to move through the fixed block 19. The connecting block 21 drives the winding wheel 22 to slide along the motor shaft 12. The winding wheel 22 moves and rotates, so that the connecting rope 23 is gradually wound around the winding wheel 22, ensuring that the connecting rope 23 on the winding wheel 22 is tightly arranged.

[0044] Example 4

[0045] On the basis of Example 3, an emergency brake mechanism is further included, which includes a gear 1 27, which is fixedly connected to the wire pulley 25 on the side close to the motor 11, and the gear 1 27 is meshed with the gear 2 28, and the gear 2 28 is rotatably set in the working chamber, and the gear 2 28 is fixedly connected to the disk 29, and a sliding groove 30 is provided in the disk 29, and a sliding shaft 31 is slidably provided in the sliding groove 30, and a spring 1 32 is fixedly provided between the sliding shaft 31 and the sliding groove 30, and the sliding shaft 31 is fixedly connected to the operating rod 33, and the operating rod 33 is correspondingly provided with a switch 34, and the switch 34 is mounted at the lower end of the mounting plate 24, and the mounting plate 24 is fixedly set in the working chamber, and the switch 34 is connected to the telescopic rod 39 through a connecting line 35, and the telescopic rod 39 is mounted at the upper end of the mounting plate 24, and the telescopic rod 39 is fixedly connected to the connecting rod 40;

[0046] A slide groove 44 is provided at the upper end of the mounting plate 24, and the slide groove 44 is slidably connected to the matching block 16. A spring 2 42 is fixedly provided between the slide groove 44 and the matching block 16. The matching block 16 is fixedly connected to the pushing block 20. The pushing block 20 is slidably connected to the sealing cavity of the sealing tube 36. A corrugated section 37 is provided in the middle of the sealing tube 36.

The connecting block 2 43 is fixedly connected to the connecting rod 40 and the sliding block 45. The sliding block 45 is slidably connected to the inclined end of the matching block 16.

[0047] The beneficial effects of the above technical solution are:

[0048] When the motor 11 is damaged or the power supply to which it is connected fails to supply power, the connecting rope 23 cannot drive the steel casing 6. At this time, the steel casing 6 will fall. In this case, the steel casing 6 drives the connecting rope 23 to move rapidly, and the connecting rope 23 drives the wire wheel 25 to rotate. The wire wheel 25 drives the gear 1 27 to rotate, and the gear 1 27 drives the gear 2 28 to rotate. The gear 2 28 drives the disc 29 to rotate. When the speed of the wire wheel 25 reaches a certain value, the sliding shaft 31 slides along the sliding groove 30 under the centrifugal action, and the spring 1 32 is compressed. The sliding shaft 31 drives the operating rod 33 to move, increasing the rotation radius of the operating rod 33. At this time, the operating rod 33 can contact the switch 34, and the control switch 34 is turned on. The switch 34 drives the telescopic rod 39 to work through the connecting wire 35. The telescopic rod 39 extends, driving the connecting rod 40 to extend, and the connecting rod 40 drives the connecting block 2 43 to move upward. The connecting block 2 43 drives the fixed plate 41 and the air cushion 38 to move upward, and the connecting block 2 43 drives the sliding block 45 along The inclined end of the mating block 16 slides, and the mating block 16 slides to the left. The slide groove 44 guides the sliding of the mating block 16. The setting of the spring 2 42 stabilizes the movement of the mating block 16. When the mating block 16 slides, it drives the pushing block 20 to move. The pushing block 20 slides along the sealed cavity of the sealing tube 36, pushing the air in the sealed cavity into the air cushion 38, making the air cushion 38 larger until the air cushion 38 contacts the motor shaft 12. The setting of the air cushion 38 is convenient for wrapping with the motor shaft 12, increasing the contact area of the air cushion 38 and the motor shaft 12. At the same time, as the air cushion 38 moves upward and the internal air pressure of the air cushion 38 gradually increases, the contact force between the air cushion 38 and the motor shaft 12 is increased, so that the friction between the air cushion 38 and the motor shaft 12 is large enough to brake the motor shaft 12, so that the connecting rope 23 cannot move, and the steel casing 6 no longer falls. The setting of the emergency braking mechanism can also prevent the steel casing 6 from falling rapidly when the motor 11 cannot work.

[0049] Example 5

[0050] On the basis of Example 2, Figure 3-Figure 4 As shown, it also includes;

[0051] Weighing sensor 1: Weighing sensor 1 is set on one of the steel pontoons 1 to detect the gravity borne by the steel pontoon 1;

[0052] Weighing sensor 2: Weighing sensor 2 is set on another steel pontoon 1 and is used to detect the gravity borne by the other steel pontoon 1;

[0053] Alarm: The alarm is installed on the steel pontoon 1;

[0054] Controller: The controller is electrically connected to the weighing sensor 1, the weighing sensor 2 and the alarm;

[0055] The controller controls the alarm based on the detection values of the weighing sensor 1 and the weighing sensor 2, including the following steps:

[0056] Step 1: The controller calculates the theoretical deformation of the double-jointed I-beam 1-2 according to the gravity of the steel pontoon 1 equipped with the weighing sensor 1 detected by the weighing sensor 1, the gravity of the steel pontoon 1 equipped with the weighing sensor 2 detected by the weighing sensor 2, and formula (1). The controller first compares the theoretical deformation of the double-jointed I-beam 1-2 with the preset deformation. If the calculated theoretical deformation of the double-jointed I-beam 1-2 is greater than the preset deformation, the controller controls the alarm to operate.

[0057] ;in, is the theoretical deformation of double-jointed I-beam 1-2, is the detection value of weighing sensor 1, is the detection value of weighing sensor 2, is the acceleration due to gravity, which is 9.8 , is the length of the web of the double I-beam. The number of double I-beams is 2. is the thickness of the web of the double I-beam. is the width of the web of the double I-beam. is the elastic modulus of double-jointed I-beam 2, is the contact area between the double I-beam 2 and the steel pontoon 1, is the cross-sectional area of the steel pontoon 1;

[0058] Step 2: If the calculated theoretical deformation of the double-jointed I-beam 1-2 is less than the preset deformation, the controller starts to calculate the theoretical safety factor of the double-jointed I-beam 1-2 according to the theoretical deformation of the double-jointed I-beam 1-2 calculated in step 1 and formula (2). The controller compares the calculated theoretical safety factor of the double-jointed I-beam 1-2 with the preset safety factor. If the calculated theoretical safety factor is less than the preset safety factor, the controller will calculate the theoretical safety factor of the double-jointed I-beam 1-2 according to the formula (2).

[0059] The theoretical safety factor of the double-jointed I-beam 2 is less than the preset safety factor, and the controller controls the alarm to sound an alarm;

[0060] ;

[0061] is the theoretical safety factor of double I-beam = 2, is the density of the river water where the steel pontoon 1 is located, is the Poisson's ratio of the double-jointed I-beam 2, It is the constraint coefficient of the flange of double I-beam 2 to the web, and its value is 1-1.23.

[0062] The beneficial effects of the above technical solution are:

[0063] Since the two steel pontoons 1 bear different gravity, the drafts of the two steel pontoons 1 are also different, but the double I-beam 1 2 and the double I-beam 2 3 connect the two steel pontoons 1 into a whole. Therefore, the two steel pontoons 1 reach the same draft under the action of the double I-beam 1 2 and the double I-beam 2 3. The weighing sensor 1 is set on one of the steel pontoons 1 to detect the gravity borne by the steel pontoon 1; the weighing sensor 2 is set on the other steel pontoon 1 to detect the gravity borne by the other steel pontoon 1; the controller is based on It is said that the gravity of the steel pontoon 1 installed with the weighing sensor 1 detected by the weighing sensor 1, the gravity of the steel pontoon 1 installed with the weighing sensor 2 detected by the weighing sensor 2 and the formula (1) are used to calculate the theoretical deformation of the double-jointed I-beam 1 2. If the theoretical deformation of the double-jointed I-beam 1 2 is greater than the preset deformation, the controller can directly control the alarm to work, indicating that there is a risk in the connection between the double-jointed I-beam 1 2 and the steel pontoon 1, and the difference in the weight bearing of the two steel pontoons 1 should be reduced or the double-jointed I-beam 1 2 should be reinforced.

[0064] If the theoretical deformation of the double-jointed I-beam 2 is less than the preset deformation, the alarm does not sound. The controller starts to calculate the theoretical safety factor of the double-jointed I-beam 2 according to the theoretical deformation of the double-jointed I-beam 2 calculated in step 1 and formula (2) (the theoretical safety factor is the ratio between the maximum shear stress to which the double-jointed I-beam 2 is subjected during deformation and the shear stress of the double-jointed I-beam 2. If the calculated maximum shear stress to which the double-jointed I-beam 2 is subjected after deformation is greater than the shear stress of the double-jointed I-beam 2, it indicates that there is a risk of fracture of the double-jointed I-beam 2 during deformation). The controller compares the calculated theoretical safety factor of the double-jointed I-beam 2 with the preset safety factor. If the calculated theoretical safety factor of the double-jointed I-beam 2 is less than the preset safety factor, the controller controls the alarm to sound, indicating that even if the double-jointed I-beam 2 is within the deformation range, the double-jointed I-beam 2 is prone to fracture during deformation, and the double-jointed I-beam 2 should also be reinforced in time.

[0065] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
