[0010] Within the optimal water level range, hoist the landscape stone from the transport ship by the floating crane ship and sail to the riverside ladder;

[0011] Fix the position of the floating crane ship, and hoist the landscape stone to the landscape stone installation position.

[0012] Further, when the floating crane ship hoists the landscape stone to the landscape stone installation position, the ship position of the floating crane ship is fixed by two stern anchors of the floating crane ship and two fixed cables of two ground bulls connected to the riverside ladder.

[0013] Further, the two stern anchors and the two fixed cables are arranged in a crosswise manner.

[0014] Further, a groove for embedding the sling of the floating crane ship is formed at the bottom of the landscape stone.

[0015] Further, a base is provided at the landscape stone installation position, and at least two support beams for placing the landscape stone are installed on the base.

[0016] Further, the support beams are arranged in the same direction as the groove.

[0017] The beneficial effect of the present invention lies in that the floating crane construction method for the giant landscape stone in the riverside ladder environment of the present invention detects the underwater terrain through an underwater robot, determines the optimal hoisting water level in combination with the working condition table of the floating crane ship, analyzes the shipping requirements at the same time, reasonably arranges the positions of the transport ship and the floating crane ship, and fixes the floating crane ship by combining the anchor chain and the ground bull to ensure the shipping passage.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Referring to Figures 1 to 4 as shown, the present invention provides a construction method for a giant landscape stone floating crane in a riverside ladder environment, including the following steps:

[0025] S1. Detect the underwater terrain changes at four locations of the riverside ladder through an underwater robot.

[0026] S2. Determine the working space on the river surface and plan the standing positions of the carrier ship 1 and the floating crane ship 2 for hoisting each landscape stone 3.

[0027] According to the shipping requirements, determine the available working space on the river surface and plan the standing positions of the carrier ship for each landscape stone and the floating crane ship.

[0028] S3. Based on the draft depth of the floating crane ship 2 after loading at different water levels and the underwater terrain changes, determine the positions that the floating crane ship 2 can reach at the riverside ladder 4 at different water levels.

[0029] S4. Based on the positions that the floating crane ship 2 can reach at the riverside ladder 4 at different water levels and the installation positions of the landscape stones 3 on the riverside ladder 4, calculate the working radius of the floating crane ship 2 at different water levels.

[0030] S5. Compare the working radius of the floating crane ship 2 at different water levels with the working condition table of the floating crane ship 2 to determine the optimal water level range for the hoisting operation of the floating crane ship 2.

[0031] Select several water levels, subtract the draft depth after the floating crane ship is loaded, combine with the detected terrain changes, determine the positions that the floating crane ship can reach at the ladder bank at different water levels, calculate the working radius at different water levels with the installation positions of the giant landscape stones, compare with the working condition table of the floating crane ship, and select the optimal water level range for the hoisting operation.

[0032] S6. Within the optimal water level range, hoist the landscape stone 3 from the carrier ship 1 by the floating crane ship 2 and sail to the riverside ladder 4.

[0033] As Figure 1 and Figure 3 shown, the bow of the floating crane ship is connected to the carrier ship through two fixed cables. The stern of the floating crane ship stabilizes the ship's body by throwing two stern anchors.

[0034] When the landscape stone is lifted over the bulkhead of the carrier ship, stop the hoisting. Release the steel cable fixed to the carrier ship, slowly sail to the position where it needs to be placed using its own power. At the same time, winch in the bow anchor and the stern anchor, and the crane slowly exits the water area of the carrier ship, then winch in the bow anchor and release the stern anchor until the floating crane ship sails to the shore.

[0035] S7, fixing the position of the floating crane 2, and hoisting the landscape stone 3 to the landscape stone 3 installation position.

[0036] When the floating crane 2 hoists the landscape stone 3 to the installation position of the landscape stone 3, the position of the floating crane 2 is fixed by two stern anchors 21 of the floating crane 2 and two fixing cables 22 connected to two ground bulls on the riverside ladder 4.

[0037] As a preferred embodiment, the two stern anchors 21 and the two fixing cables 22 are arranged crosswise.

[0038] Two stern anchors are thrown 80 meters away from the water foam line and handed over to the floating crane. Both stern anchors use anchor chains to prevent affecting the normal passage of passing ships. After the landscape stones are lifted from the carrier ship, two cross cables are extended from the bow of the floating crane and connected to the land bulls on the shore.

[0039] After the floating crane reaches the shore, the floating crane is fixed in place using the ground bulls on the shore, and the position of the ship is fixed using the rudder, and the landscape stone lifting begins.

[0040] The bottom of the landscape stone 3 is provided with a groove for the sling of the floating crane 2 to be embedded. The installation position of the landscape stone 3 is provided with a base, and the base is installed with at least two supporting beams for the landscape stone 3 to be placed. The supporting beams are arranged in the same direction as the groove.

[0041] A groove for the sling is carved into the bottom of the giant landscape stone. A supporting beam (i.e., an elevated I-beam) is set on the base and parallel to the groove to facilitate the smooth removal of the sling after it is hoisted into place.

[0042] After the landscape stone falls steadily to the base, the commander observes the posture of the landscape stone and the condition of the pier to ensure that they are correct. Then, the commander gives the order to remove the hook, and the crane slowly reels in the rope to complete the lifting.

[0043] The method for floating crane construction of giant landscape stones in a riverside ladder environment of the present invention detects underwater terrain through an underwater robot, determines the optimal lifting water level in combination with the working condition table of the floating crane, analyzes shipping requirements, rationally arranges the positions of the carrier ship and the floating crane, and fixes the floating crane by combining anchor chains and ground bulls to ensure shipping passage. This solves the problem that giant landscape stones in riverside spaces cannot be transported and lifted on land. The construction process is more convenient, fast, safe and reliable. Moreover, compared with traditional construction methods, the construction cost is lower and the construction speed is faster.

[0044] The above description is only a preferred embodiment of the present application and an explanation of the technical principles applied. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
