Description

Technical Field

[0001] The invention relates to a reservoir of a water conservancy and hydropower project, in particular to a ship moving method used in a shipyard in a water conservancy and hydropower project. Background Art

[0002] In the reservoirs of water conservancy and hydropower projects in northern my country, it is often necessary to place some special-purpose ships, such as mowing boats, salvage boats, speedboats, transport ships, etc. Since the weather in the north is relatively cold in winter, the water surface of the reservoir may freeze, and the above-mentioned ships do not need to work in winter. Therefore, in order to prevent these ships from freezing and being damaged in winter, the reservoir management department needs to build a boat parking lot at a suitable location on the shore of the reservoir to park these ships. However, the reservoirs in the north are different from those in the south. The reservoir scenes in the south are surrounded by many rivers. The use characteristics of various types of ships are that the ships basically do not need to be moved out of the water after being placed in the water. Even when the ships need to be repaired, they can be achieved by using docks. The special features of ship transfer in the docks of reservoirs in the north are: (1) It is inconvenient to build docks in reservoirs and the cost is high. It is impossible for ships to drive to the docks and stop by themselves. Ship transfer equipment is required. (2) There is a fixed two-way movement demand for ship transfer in reservoirs, that is, the ships need to be moved to the docks every winter, and the ships need to be moved from the docks to the reservoirs after the winter is over. Therefore, studying the ship transfer scheme that meets the needs of northern reservoirs is the key problem to be solved by the present invention. Summary of the invention

[0003] The present invention aims to provide a method for moving ships in a shipyard in a water conservancy and hydropower project, so as to realize convenient and low-cost ship moving in northern reservoirs and facilitate the management and operation of reservoir ships.

[0011] Step 1.3.2, multiple rows of rubber rollers are installed on a rectangular frame near the side of the shipyard, and the axes of the rubber rollers are perpendicular to the axis of the track;

[0012] Step 2, ship moving method:

[0013] Step 2.1, the ship moves from the reservoir to the boat dock:

[0014] 2.1.1, firstly, adjust the connection length of the connecting rod according to the size of the ship to adapt to ships of different lengths, and then operate the winch to send the ship moving vehicle along the track to below the preset water surface of the reservoir, so that the upper edge of the rubber roller is flush with the water surface of the reservoir area or exposed above the water surface;

[0015] 2.1.2, operate the ship so that its center line coincides with the center line of the boat moving vehicle, then drive into the water surface above the boat moving vehicle, and use the momentum of the ship's movement to place the bow on the rubber roller to stop the ship;

[0016] 2.1.3, operate the winch to pull the ship moving vehicle with ropes to move the ship along the track to the preset position in the ship parking building;

[0017] 2.1.4, operate the bridge crane to lift the ship and move it to the preset ship storage position;

[0024] Figure 2 It is a structural schematic diagram of the boat moving vehicle of the present invention. DETAILED DESCRIPTION

[0025] like Figure 1 , 2 As shown, the method for moving a ship at a shipyard in a water conservancy and hydropower project of the present invention comprises the following steps:

[0026] Step 1, construction of the ship moving system:

[0027] Step 1.1, construct a boat dock 1 on the bank of the reservoir, the floor of the boat dock 1 is higher than the normal water level 2 of the reservoir, the gate of the boat dock 1 is opened toward the reservoir area, and a bridge crane 3 and a winch 4 are installed in the boat dock 1;

[0028] Step 1.2, a reinforced concrete pier 6 is constructed on the bottom 5 of the shipyard building 1 facing the gate, and then two parallel tracks 7 are installed; the two parallel tracks 7 are installed from the shipyard building 1 along the slope of the embankment to the pier 6, and are fixedly connected to the pier 6;

[0029] Step 1.3, make a boat moving vehicle, such as Figure 2 As shown:

[0030] Step 1.3.1, the boat moving vehicle comprises two rectangular frames 8, 9, on which four track wheels 8.1, 9.1 matching two parallel tracks 7 are respectively installed, and a connecting rod 8.2, 9.2 is respectively hinged on both sides of the opposite ends of the two rectangular frames 8, 9, and a plurality of pin holes 8.3, 9.3 are opened at equal intervals on each connecting rod 8.2, 9.2. The two rectangular frames 8, 9 are connected as a whole through the connecting rods 8.2, 9.2 on the corresponding sides and the pin shaft 10 passing through the pin holes. A traction earring 11 for connecting with the rope of the winch 4 is installed on the rectangular frame 9 close to the side of the shipyard 1. ;

[0031] Step 1.3.2, two rows of rubber rollers 12 are installed on the rectangular frame 9 close to one side of the shipyard building 1, and the axes of the rubber rollers 12 are perpendicular to the axes of the two parallel tracks 7.

[0032] Step 2, ship moving method:

[0033] Step 2.1, the vessel 13 moves from the reservoir to the boat dock 1:

[0034] 2.1.1, firstly, the connection length of the connecting rods 8.2 and 9.2 is adjusted according to the size of the ship 13 to adapt to ships 13 of different lengths; that is, by adjusting the pin shaft 10 to penetrate into the pin holes at different positions, the length of the entire connecting rod after connection is adjusted; the purpose of this design is that since the ships in the reservoir are of different sizes and lengths, by adjusting the length of the connecting rod, ships 13 of different lengths can be accommodated to be parked on the ship moving vehicle;

[0035] Then operate the winch 4 to send the boat moving vehicle along the two parallel tracks 7 to below the preset water surface of the reservoir, so that the upper edge of the rubber roller 12 is flush with the water surface 14 of the reservoir area or exposed to the water surface;

[0036] 2.1.2, operate the ship 13 so that its center line coincides with the center line of the ship moving vehicle, then drive into the water surface above the ship moving vehicle, and use the momentum of the ship 13 to place the bow on the rubber roller 12 to stop the ship;

[0037] The function of the rubber rollers 12 is that when the ship 13 drives toward the ship moving vehicle, it first hits the rubber rollers 12 to avoid damage to the ship 13 due to a violent collision. At the same time, after the ship 13 hits the rubber rollers 12, the friction force can be increased, so that when the ship 13 is pulled upward, the ship 13 can gradually stop completely on the ship moving vehicle.

[0038] 2.1.3, operate the winch 4 to pull the ship moving vehicle through the rope to move the ship along two parallel tracks 7 to the preset position of the ship parking building 1;

[0039] 2.1.4, operate the bridge crane 3 to lift the ship 13 and move it to the preset ship storage position 15, and the ship transfer is completed;

[0040] Step 2.2, the vessel 13 moves from the boat dock 1 to the reservoir:

[0041] Step 2.2.1, when the ship 13 needs to be moved from the shipyard 1 to the reservoir, the bridge crane 3 is operated to lift the ship 13 from the ship storage position 15 and place it on the ship moving vehicle;

[0042] Step 2.2.2, operate the winch 4 to pull the ship moving vehicle along two parallel tracks 7 toward the reservoir through ropes. When the ship moving vehicle enters the water until the entire ship 13 floats and leaves the ship moving vehicle, operate the ship 13 to move away; then, operate the winch 4 to pull the ship moving vehicle along two parallel tracks 7 to the ship parking lot 1 through ropes, and the ship moving is completed.
