[0025] Example:

[0026] like Figure 1As shown, the utility model proposes a water vertical and horizontal transportation system used for the construction of the upper structure of a high-pile dock, including two steel pipe pile foundations 1, the bottom of the steel pipe pile foundation 1 penetrates into the bottom of the mud surface line 23 and is higher than the water surface line 24, and the steel pipe pile foundation 1 bears the weight of the construction hoisting objects, the weight of the equipment, the operating strength, the influence of geology and working conditions, etc. It also includes a bottom cross beam 2 arranged on the steel pipe pile foundation 1, a foundation beam 3 and a pedestrian bridge 4 are installed on the bottom cross beam 2, a gantry track 5 is fixedly installed on the foundation beam 3, and a water gantry crane 7 is installed on the gantry track 5. The bottom cross beam 2 transmits the weight of the construction hoisting objects, the weight of the equipment, the operating strength, the influence of geology and working conditions, etc. The foundation beam 3 serves as the foundation of the water gantry crane 7, fixes the gantry track 5, and transmits the weight of the construction hoisting objects, the weight of the equipment, the operating strength, the influence of geology and working conditions, etc. The pedestrian bridge 4 is used for construction personnel and maintenance personnel to pass. A first driving device is provided on the steel pipe pile foundation 1 for driving the water gantry crane 7 to move along the gantry track 5. The water gantry crane 7 is a main equipment for hoisting components, materials, and tools, and the longitudinal displacement of the hoisted objects is achieved through the first driving device.

[0027] A cable laying platform 6 is arranged on one of the steel pipe pile foundations 1. The cable laying platform 6 is used to lay the cables of the water gantry crane 7. The water gantry crane 7 is equipped with an electric winch 8, and the electric winch 8 is equipped with a second driving mechanism for driving the electric winch 8 to move along the water gantry crane 7. The electric winch 8 is used to hoist the main equipment of components, materials, and tools, and the horizontal displacement of the hoisted weight is achieved through the second driving mechanism.

[0028] A steel wire rope 9 is fixedly installed on the electric hoist 8, and a trim box 10 is fixedly installed on one end of the steel wire rope 9, and a hook 11 is fixedly installed on the trim box 10. Components, materials, and tools are hoisted by the hook 11.

[0029] When lifting cargo, the following steps should be followed:

[0030] Step 1: Before operating the equipment system, technical explanations must be conducted to clarify the weight, specifications, dimensions and other information of the items to be transferred, and operators must receive pre-shift education on operating procedures, construction methods, safety precautions, etc.;

[0031] Step 2: The operator operates the water gantry crane 7 and the electric winch controller to move the water gantry crane 7 to the object to be transferred, and the electric winch 8 is synchronously put into place;

[0032] Step 3: Lower the wire rope 9 connected to the hook 11, lower the hook 11 above the hanging object, and the construction personnel fix the hanging object on the hook 11;

[0033] Step 4: Test lifting, that is, lifting the heavy object to no more than 0.5 meters, and then braking when it descends close to the ground. The lifting object should be ensured to be stable and the wire rope 9 should be checked for normal use before the next step can be carried out;

[0034] Step 5: The operator operates the controllers of the water gantry crane 7 and the electric winch 8 to transfer the hanging object to the target position;

[0035] Step 6: Install or place the hanging objects. The process should be carried out smoothly and orderly.

[0036] Step 7: The water gantry crane 7 is reset, moved to a safe parking area, the limiter is locked, and the safety cables are fixed.

[0037] like Figure 2-Figure 4 As shown, an anti-sway component is installed in the trim box 10, and the anti-sway component applies resistance to the wire rope 9 in the opposite direction of the swaying direction of the wire rope 9. Due to the particularity of the operating environment of the water gantry crane 7 on the dock compared to the gantry crane on the ground, special attention should be paid to the sea breeze problem. The water gantry crane 7 needs to consider the wind force level, which will affect the stability and safety of the hoisting. When the sea breeze is strong, the sea breeze will blow the hoisted cargo to move, and at this time it will drive the wire rope 9 to swing. The swing of the cargo may cause damage to the packaging, structural damage or functional failure, especially for precision instruments or fragile items. And the swinging of the cargo may hit nearby facilities, ships or personnel, causing personal injury or property loss.

[0038] The anti-sway component includes a traction rope 12 fixedly installed in the trim box 10, and a plurality of installation boxes 13 are fixedly installed at the other end of the traction rope 12, and two adjacent installation boxes 13 are fixedly connected by a connecting block. When the cargo swings under the influence of the sea breeze, the trim box 10 will be driven to swing synchronously. At this time, the installation box 13 inside the trim box 10 is connected to the trim box 10 by the traction rope 12. The connection method here is a flexible connection, so that under the gravity of the installation box 13, the installation box 13 can maintain a vertical state. At this time, the shaking trim box 10 will have a certain angle with the installation box 13. The gravity inside the trim box 10 can be decomposed into a pulling force in the opposite direction of the shaking of the trim box 10, thereby reducing the shaking degree of the trim box 10. However, in order to resist stronger sea breezes, it is necessary to continuously increase the gravity of the installation box 13, which leads to an increase in the energy consumption of the electric winch 8, which is not conducive to energy saving and emission reduction.

[0039] The anti-sway component also includes a counterweight assembly fixedly installed in the installation box 13, and the counterweight assembly includes two support rods 14 fixed in the installation box 13, and a first connecting plate 15 is rotatably installed on the support rods 14, and a counterweight block 16 is fixedly installed on the first connecting plate 15. When the first connecting plate 15 rotates, it will drive the counterweight block 16 to rotate, and the rotating counterweight block 16 will generate centrifugal force, which will act on the support rods 14 and then on the installation box 13, so that the pulling force applied by the installation box 13 to the balance box 10 can be increased in disguise through the rotating counterweight block 16, so as to resist stronger sea wind.

[0040] The anti-sway component also includes a stamping mechanism installed on the installation box 13, and the stamping mechanism drives multiple counterweights 16 to perform periodic reciprocating swings. The stamping mechanism includes a motor 17 fixedly installed on the installation box 13 located at the bottom, an eccentric wheel 18 is fixedly installed on the output shaft of the motor 17, and a connecting rod 19 is rotatably installed on the eccentric wheel 18. A transmission rod 20 is slidably installed in multiple installation boxes 13, and the other end of the connecting rod 19 is rotatably connected to the transmission rod 20. A plurality of second connecting plates 21 are fixedly installed on the transmission rod 20, and the second connecting plates 21 correspond to the installation boxes 13 one by one. The second connecting plates 21 are located inside the installation box 13, and a driving rod 22 is rotatably installed on the second connecting plate 21, and the driving rod 22 corresponds to the first connecting plate 15 one by one and is rotatably connected. The starting motor 17 drives the eccentric wheel 18 to rotate, and the rotating eccentric wheel 18 will drive the connecting rod 19 to rotate. The rotation of the connecting rod 19 can drive the transmission rod 20 to slide in the installation box 13, thereby driving the second connecting plate 21 to slide back and forth, and then pushing the driving rod 22 to rotate. The rotating driving rod 22 will push the two first connecting plates 15 located in the same installation box 13 to rotate periodically. The rotation process is a small amplitude approaching and moving away from each other, so that the counterweight block 16 can rotate and generate sufficient centrifugal force to act on the installation box 13, so that the installation box 13 can produce sufficient pulling force on the balancing box 10 to overcome the lateral force on the balancing box 10 that causes the balancing box 10 to rotate.

[0041] The working principle of this embodiment is as follows: the operator operates the water gantry crane 7 and the electric winch controller to move the water gantry crane 7 to the object to be transferred, the electric winch 8 is synchronously in place, the wire rope 9 connected to the hook 11 is lowered, the hook 11 is lowered above the hanging object, the construction personnel fix the hanging object on the hook 11, the operator operates the water gantry crane 7 and the electric winch 8 controller to transfer the hanging object to the target position, when the hanging cargo is shaken by the sea breeze, the starting motor 17 drives the eccentric wheel 18 to rotate, and the rotating eccentric wheel 18 drives the connecting rod 19 to rotate, through The rotation of the connecting rod 19 can drive the transmission rod 20 to slide in the installation box 13, thereby driving the second connecting plate 21 to slide back and forth, and then driving the driving rod 22 to rotate. The rotating driving rod 22 will drive the two first connecting plates 15 located in the same installation box 13 to rotate periodically. The rotation process is to approach and move away from each other in a small range, so that the counterweight block 16 can rotate and generate sufficient centrifugal force to act on the installation box 13, so that the installation box 13 can produce enough pulling force on the trim box 10 to overcome the lateral force on the trim box 10 that causes the trim box 10 to rotate. The gravity inside the trim box 10 and the pulling force on the trim box 10 caused by the counterweight block 16 can be decomposed into a pulling force in the opposite direction of the shaking of the trim box 10, thereby reducing the shaking degree of the trim box 10.

[0042] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
