It may also be understood that the features described in conjunction with the individual embodiments may be used in other embodiments.

[0028] To solve the above problems, Figures 1 to 5As shown, the present invention provides a beam erection device, including a frame 1 and a lifting mechanism, the lifting mechanism including a main beam 24, a first lifting assembly 21 and a second lifting assembly 22, the main beam 24 is connected to the front end of the frame 1, the main beam 24 is used to extend along the width direction of the bridge body 31, the two first lifting assemblies 21 are respectively connected to the two ends of the main beam 24 in the length direction, the two second lifting assemblies 22 are slidably connected to the main beam 24 along the length direction of the main beam 24, and are located between the two first lifting assemblies 21, the first lifting assembly 21 has a first hook 211 at the lower end, the second lifting assembly 22 has a lifting beam 221 extending along the length direction of the bridge body 31 at the lower end, the lifting beam 221 has second hooks 222 at both ends along the length direction, the first hook 211 and the second hook 222 are both used to lift the truss 33 or the bridge deck 32.

[0029] In this embodiment, a frame 1 is set as the main body of the beam-raising device, and a main beam 24 extending along the width direction of the bridge body 31, that is, the Y-axis direction, is set at the front end of the frame 1, that is, one end in the positive direction of the X-axis. Two groups of first lifting assemblies 21 and two groups of second lifting assemblies 22 are provided on the main beam 24, wherein the two groups of first lifting assemblies 21 are respectively arranged at the two ends of the main beam 24 along the positive and negative directions of the Y-axis, and the two groups of second lifting assemblies 22 are arranged on the main beam 24, and their positions are located between the two groups of first lifting assemblies 21, and the two groups of second lifting assemblies 22 can slide relative to the main beam 24 along the Y-axis direction. A first hook 211 is provided at the lower end of the first lifting assembly 21, and a beam 221 extending along the X-axis direction is provided at the lower end of the second lifting assembly 22, and second hooks 222 are provided below both ends of the beam 221 along the X-axis direction. When working, first, as shown in Figure 3 As shown, the first lifting component 21 and the second lifting component 22 located in the negative direction of the Y-axis of the beam erecting device are used in combination to lift the beam piece 33 to be installed in the negative direction of the Y-axis. There is a first hook 211 and two second hooks 222 acting on the beam piece 33. The three force points enable the beam piece 33 to be lifted stably, and the two second hooks 222 can move in the Y-axis direction with the second lifting component 22 to adjust the lifting angle of the beam piece 33 so that the angle of the beam piece 33 is consistent with the angle of the previously installed beam piece 33, so as to facilitate the connection of the beam piece 33 to the previously installed beam piece 33. At the same time, the first lifting component 21 and the second lifting component 22 located in the positive direction of the Y-axis of the beam erecting device are used in combination to lift the beam piece 33 to be installed in the positive direction of the Y-axis. After the beam pieces 33 on both sides are installed, as shown in FIG. Figure 4As shown, two second lifting assemblies 22 are used to jointly lift the bridge deck 32, and four second lifting hooks 222 work together to allow the bridge deck 32 to rise smoothly until it is connected to the previous bridge deck 32. The present invention uses two first lifting assemblies 21 and two second lifting assemblies 22 in combination, so that one beam erection device can complete the lifting work of the bridge, thereby improving work efficiency, and the speed of multiple lifting assemblies on one beam erection device is better controlled, and the coordinated use can improve the efficiency of bridge erection.

[0030] Alternatively, if Figure 5 As shown, telescopic cylinders 4 are provided on the lower surfaces of the left and right sides of the front end of the frame 1, and the two telescopic cylinders 4 are located on the front side of the main beam 24. The fixed ends of the telescopic cylinders 4 are rotatably connected to the frame 1, and the telescopic ends of the telescopic cylinders 4 are connected with steel wire ropes and third hooks in sequence. The third hook is used to hoist the truss piece 33, and the hoisting position of the third hook is the same as the hoisting position of the first hook 211.

[0031] In this embodiment, two telescopic cylinders 4 are arranged on the lower surface of one end of the frame 1 facing the positive direction of the X-axis. The two telescopic cylinders 4 are respectively located at the two ends of the frame 1 along the positive and negative directions of the Y-axis, and are used to respectively hoist the trusses 33 on both sides of the bridge body. The fixed end of the telescopic cylinder 4 is rotatably connected to the connection of the frame 1. The telescopic cylinder 4 can rotate arbitrarily relative to the frame 1 and below the frame 1. The telescopic end of the telescopic cylinder 4 is connected to a steel wire rope, and the other end of the steel wire rope is provided with a third hook. When working, Figure 5 As shown, the truss 33 and the bridge deck 32 have been connected to the previous section of the bridge body 31. At this time, the truss 33 and the bridge deck 32 need to be connected together. Since the truss 33 is only connected to the previous truss 33 in the negative direction of the X-axis at this time, the end of the truss 33 facing the positive direction of the X-axis is not subject to external force, and the projection of the truss 33 on the plane where the Y-axis and Z-axis are located is a right triangle, and its right-angled sides extend along the Y-axis and Z-axis directions. Then, the center of gravity of the truss 33 will be offset in the direction away from the center of the frame 1 under the action of its own gravity. At this time, the third hook is connected to the truss 33, and the connection position is the same as the lifting position of the first hook 211, that is, Figure 5 At point a in the figure, since the two telescopic cylinders 4 are located on the front side of the main beam 24, and the lifting position is located at the end of the truss 33 away from the bridge deck 32, the telescopic cylinders 4 and the wire rope are inclined to pull the third hook, the telescopic cylinders 4 contract, and the third hook tightens the truss 33. The force applied by the third hook to the truss 33 includes a component force toward the center of the frame 1. This component force acts on the truss 33 to prevent the center of gravity of the truss 33 from shifting toward the outside of the frame 1, making it easier to connect the truss 33 to the bridge deck 32 later.

[0032] Specifically, the fixed end of the telescopic cylinder 4 can be connected to the frame 1 through a universal wheel.

[0033] Alternatively, if Figure 1As shown, the main beam 24 is used to slide relative to the frame 1 along the length direction of the bridge body 31.

[0034] In this embodiment, by setting the main beam 24 to be able to slide in the X-axis direction relative to the frame 1, the first lifting assembly 21 and the second lifting assembly 22 can be driven to move in the X-axis direction to adjust the positions of the hoisted trusses 33 and the bridge deck 32 in the X-axis direction, thereby facilitating the connection of the trusses 33 and the bridge deck 32 to the trusses 33 and the bridge deck 32 of the previous section of the bridge body 31.

[0035] Alternatively, if Figure 1 , Figure 4 and Figure 5 As shown, the frame body 1 is a hollow frame structure, and a beam storage plate 11 is provided inside the frame body 1 , and the beam storage plate 11 is used to load the bridge deck 32 .

[0036] In this embodiment, the bridge deck 32 includes an upper and lower side, the upper bridge deck is connected between the upper ends of the two trusses 33, and the lower bridge deck is connected between the lower ends of the two trusses 33. By setting the frame 1 as a hollow structure, a beam storage plate 11 is provided inside the frame 1. During operation, the upper and lower bridge decks can be first hoisted into the beam storage plate 11 through the second lifting assembly 22, and then the lower bridge deck 32 and the upper bridge deck 32 can be hoisted and installed in turn, avoiding directly hoisting and installing the upper and lower bridge decks 32 from the ship, which would cause conflicts in position.

[0037] Alternatively, if Figure 1 and Figure 4 As shown, a third lifting assembly 23 is also provided on the main beam 24. The third lifting assembly 23 is located between the two second lifting assemblies 22 and is used to move along the length direction of the main beam 24. The third lifting assembly 23 is used to lift the bridge deck connecting plate.

[0038] In this embodiment, a third lifting assembly 23 is arranged on the main beam 24, and the third lifting assembly 23 is located between the two second lifting assemblies 22. The third lifting assembly 23 can slide on the main beam 24 along the Y-axis direction without affecting the operation of the second lifting assembly 22. The third lifting assembly 23 lifts the bridge deck connecting plate from the ship, and the third lifting assembly 23 moves in the Y-axis direction to facilitate the installation position of the corresponding bridge deck connecting plate. Since the bridge deck connecting plate is lighter than the truss 33 and the bridge deck 32, the power of the third lifting assembly 23 is smaller than that of the first lifting assembly 21 and the second lifting assembly 22, the lifting speed is faster, and energy waste is avoided.

[0039] Alternatively, if Figure 1 As shown, a lifting ring 12 is provided at the rear end of the frame body 1, and a lifting ear is provided on the upper surface of the bridge body 31, and the lifting ring 12 is detachably connected to the lifting ear.

[0040] In this embodiment, a lifting ring 12 is provided at the rear end of the frame 1, i.e., at the lower part of the end facing the negative direction of the X-axis, and a lifting ear detachably connected to the lifting ring 12 is provided on the bridge body 31. The lifting ring 12 and the lifting ear are used together. When connected together, they can provide pulling force for the beam erecting equipment to prevent the beam erecting equipment from tilting due to the excessive weight of the hoisted truss 33 or the bridge deck 32. After the hoisting is completed, the lifting ring 12 and the lifting ear are disassembled to facilitate the removal of the bridge erecting equipment.

[0041] Alternatively, if Figure 1 As shown, a plurality of legs 13 are provided on the lower surface of the frame body 1 , and the plurality of legs 13 are used to support the upper surface of the bridge body 31 .

[0042] In this embodiment, a plurality of legs 13 are provided on the lower surface of the frame body 1 so that the bridging equipment can be stably supported on the bridge body 31 .

[0043] Alternatively, if Figure 1 , Figure 2 and Figure 6 As shown, the upper surface of the bridge body 31 is provided with a track beam 5 extending along the length direction of the bridge body 31, and a sliding cylinder and a telescopic block 6 are provided on the track beam 5. The telescopic block 6 is slidably connected to the track beam 5, and the sliding cylinder is drivingly connected to the telescopic block 6. The telescopic block 6 is used to telescope in the vertical direction, and the upper surface of the telescopic block 6 is used to abut against the lower surface of the frame 1.

[0044] In this embodiment, a track beam 5 extending along the X-axis direction is set on the upper surface of the bridge body 31, and a telescopic block 6 is provided on the track beam 5. The telescopic block 6 can be telescoped along the Z-axis direction. A sliding cylinder is also provided on the track beam 5. The telescopic block 6 can slide along the track beam 5 in the X-axis direction under the drive of the sliding cylinder. When working, the telescopic block 6 extends to the upper end of the telescopic block 6 to lift the frame 1. The sliding cylinder drives the telescopic block 6 to move in the X-axis direction, and drives the frame 1 to move in the X-axis direction to change the position of the frame 1 in the X-axis direction, so that after a section of the bridge body 31 is erected, the frame 1 can move in the positive direction of the X-axis to continue to erect the next section of the bridge body 31.

[0045] Specifically, there can be multiple telescopic blocks 6, and multiple telescopic blocks 6 make the frame 1 rise and fall more smoothly. The telescopic block 6 can be a structure such as a hydraulic cylinder. The upper surface of the track beam 5 can be provided with a slide groove extending along the X-axis direction, and the telescopic block 6 is embedded in the slide groove and slides along the X-axis direction.

[0046] Alternatively, if Figure 1 , Figure 2 and Figure 6 As shown, a plurality of pads 7 are provided under the track beam 5 , and the pads 7 are used to be connected to the upper surface of the bridge body 31 . The positions of the plurality of pads 7 are used to correspond to the positions of the partition plates of the bridge body 31 .

[0047] In this embodiment, multiple pads 7 are arranged under the track beam 5. The positions of the pads 7 correspond to the positions of the partitions in the bridge body 31. The pads 7 are located directly above the partitions. All the gravity of the beam erection equipment acts on the partitions through the pads 7. The partitions have high structural strength and good supporting performance, which prevents the track beam 5 from exerting pressure on the bridge body 31 and damaging the bridge body 31 between two adjacent partitions.

[0048] Optionally, the first lifting assembly 21 and the second lifting assembly 22 both include a winch and a steel wire, one end of the steel wire is used for lifting, and the other end is drive-connected to the winch, and the winch is connected to the main beam 24 .

[0049] In this embodiment, a steel wire rope and a winch are provided, and the winch is connected to the main beam 24, so that the winch drives the steel wire rope to pull the hook up and down to play a lifting role.

[0050] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
