Description

Technical Field

[0001] The invention relates to the technical field of navigation marks, and in particular to a mechanized special hoisting device for a floating drum. Background Art

[0002] Channel maintenance and management in the shipping industry is an important part of the stable operation and development of the shipping industry. The normal operation of navigation marks, which are important landmarks of ship navigation channels, is an important part of channel maintenance. There are three aspects of navigation mark maintenance: one is to set up navigation marks; the second is to remove navigation marks; and the third is navigation mark maintenance and upkeep. All three work contents have the work link of lifting the navigation mark buoy, that is, lifting the navigation mark buoy from the ship to the water or lifting the navigation mark buoy from the water to the deck of the ship. There are two existing methods of lifting the buoy: one is to manually hook the crane hook to the lifting ring on the buoy. Since it is an on-water operation, this operation method poses a greater threat to the life safety of construction workers; the other is to mechanically put the winch wire rope on the bottom of the navigation mark buoy, and then use the winch to directly drag the navigation mark buoy onto the ship deck. In addition to the personal safety issue, this method has a relatively large damage to the hull and buoy during the construction process due to the direct contact and friction between the navigation mark buoy and the hull, and the swaying of the hull on the water, which causes collisions between the navigation mark buoy and the hull. To this end, we propose a mechanized floating drum special lifting device. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-2 As shown, the present invention provides a technical solution: a mechanized floating drum special lifting device, comprising an annular hanging beam 1, and a universal wheel supporting mechanism 5, an alignment and straightening mechanism 6 and a rotary driving device 4 arranged on the annular hanging beam 1;

[0027] The ring beam 1 is connected to the lifting equipment through a lifting rope. The ring beam 1 is wrapped around the buoy and connected to the lifting ring on the buoy through no less than two evenly distributed hooks 3. The ring beam 1 is an annular box-shaped steel structure, and four evenly distributed steel lifting rings 2 are installed on its upper part. The lifting rings 2 are used to connect the ring beam 1 to the crane. Directly below the lifting rings 2, four double-ear hooks 3 are evenly distributed on the bottom of the ring beam 1, which are used to connect the ring beam 1 to the navigation buoy. The number of double-ear hooks 3 matches the number of lifting rings on the buoy and is not limited to four.

[0028] like Figure 3-4As shown, at least two evenly distributed universal wheel support mechanisms 5 are arranged at the bottom of the annular hanging beam 1. The annular hanging beam 1 contacts the floating drum through the universal wheel support mechanisms 5 and rolls along the floating drum. Four universal wheel support mechanisms 5 are installed at the bottom of the annular hanging beam 1. The universal wheels are welded to the annular hanging beam 1 and arranged at an azimuth angle of 45° with the hook 3. They play the role of supporting the deadweight of the special sling, and at the same time can ensure that the relative spacing between the sling and the floating drum is correct, providing conditions for subsequent alignment and rotation of the hook.

[0029] like Figure 3-4 As shown, the annular beam 1 is provided with no less than three evenly distributed alignment and straightening mechanisms 6, which push the side wall of the buoy through an electric push rod so that the center line of the annular beam 1 and the center line of the navigation mark buoy are within a specified error range; the alignment and straightening mechanism 6 and the rotary drive device 4 are both controlled by an electrical control system, and the electrical control system adopts wired remote control or wireless remote control.

[0030] There are four universal wheel supporting mechanisms 5 , which are arranged at an azimuth angle of 45° with the hook 3 .

[0031] The alignment and straightening mechanism 6 is composed of an electric push rod, a lever mechanism and a clamping wheel. One end of the lever mechanism is connected to the electric push rod, and the other end is connected to the clamping wheel. The operation of the electric push rod drives the lever mechanism to set one end of the clamping wheel to push the side wall of the floating drum, so that the center line of the annular suspension beam 1 and the center line of the navigation mark floating drum are within the specified error range.

[0032] The alignment and straightening mechanism 6 is installed on the upper part of the annular suspension beam 1 and is located directly above the universal wheel supporting mechanism 5 .

[0033] The alignment and straightening mechanism 6 is installed on the upper part of the annular beam 1, just above the universal wheel support mechanism 5. The alignment and straightening mechanism 6 is composed of an electric push rod, a lever mechanism and a clamping wheel. After the annular beam 1 falls on the spherical top of the floating drum, the alignment and straightening mechanism 6 is started to straighten the special sling, so that the center line of the special sling and the center line of the navigation mark floating drum are within the specified error range, providing conditions for further slewing hook action. The specified error range can be -15mm to 15mm, which can be set according to needs.

[0034] like Figure 5 As shown, the annular suspension beam 1 is provided with no less than two evenly distributed slewing drive devices 4, which drive the annular suspension beam 1 to rotate relative to the floating drum, so that the hook 3 on the annular suspension beam 1 hooks the lifting ring on the floating drum.

[0035] The slewing drive device 4 is composed of a driving motor, a reduction gearbox and a driving wheel. The driving motor drives the driving wheel to rotate along the floating drum through the reduction gearbox, and drives the hook 3 of the annular hanging beam 1 to rotate and hook the lifting ring of the floating drum.

[0036] The driving wheel is a hub made of a steel structure, and a rubber rim is mounted on the hub to increase friction.

[0037] The slewing drive device 4 is installed at the bottom of the annular beam 1, and is arranged at an azimuth angle of 20° with the universal wheel support mechanism 5. The slewing drive device 4 is installed at the bottom of the annular beam 1, and is arranged at an azimuth angle of 20° with the universal wheel support mechanism 5. The slewing drive device 4 consists of a drive motor, a reduction gearbox and a drive wheel. The drive wheel is a hub made of steel structure, and the rubber wheel rim mounted on the hub is used to increase friction. After the alignment is successful, the slewing drive device 4 is started to rotate the special sling until the hook 3 enters the lifting ring 2 on the floating drum and stops automatically.

[0038] Special lifting equipment operation process:

[0039] 1. Use wire rope to connect the crane and this special lifting device;

[0040] 2. Start the crane and put the special lifting device on the navigation mark buoy from above the navigation mark buoy;

[0041] 3. Place the special lifting device on the spherical part of the navigation mark buoy, and preliminarily correct the location of the annular hanging beam 1 so that the universal wheel support mechanism 5 can correctly contact the spherical part of the buoy to support the weight of the main body;

[0042] 4. Determine the order of starting the alignment and righting mechanisms 6 according to the contact angle between the special spreader and the float, until all four alignment and righting mechanisms 6 are in place, confirming that the center line of the special spreader and the center line of the navigation mark float are within the specified error range;

[0043] 5. Start the rotary drive device 4 to drive the special lifting device to perform rotary motion, so that the hook 3 is accurately inserted into the floating drum ring 2;

[0044] 6. Start the crane to lift the navigation mark buoy to the designated position and end the operation process.

[0045] In the present invention, the buoy can be covered from the top of the buoy, and the universal wheel support mechanism 5 supports the weight of the sling itself and is placed on the spherical top of the buoy. The sling is buckled directly above the buoy through the alignment action of the alignment mechanism 6, and the rotary mechanism is driven to make the hook 3 set at the lower part of the annular suspension beam 1 hook the lifting ring 2 on the upper part of the spherical surface of the buoy. When the electrical control system detects that the sling is correctly connected to the buoy, it sends a connection success signal to notify the operator to start the crane to complete the operation of lifting the buoy. The use of this sling can avoid the dangerous operation of manually hanging the hook 3, reduce the risk of direct contact between the buoy and the hull, avoid human damage to the hull and the buoy during the operation, improve the degree of mechanized construction, and at the same time reduce the labor intensity and improve the safety of construction personnel.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
