Description

Technical Field

[0001] The utility model relates to the technical field of tamping integrated ship construction, in particular to a system for controlling the movement of a trolley for tamping integrated ship. Background Art

[0002] At present, there is no ship that integrates riprap, tamping and leveling at home and abroad, and meets the construction standards of the upper caisson installed directly on the foundation. The existing riprap and tamping ship with similar functions is respectively provided with a first track and a second track on the left and right sides of the main deck, and the slide trolley and the tamping platform trolley are arranged on the first track and the second track respectively, and the movement of the trolley is driven and pulled by the winches on both sides of the respective tracks. The above-mentioned existing trolley movement method also has the following shortcomings: the number of winches designed in the existing application technology is large, the total installed power is large, the main deck occupies a lot of space, the construction cost is high, and there is no space for the enclosure cabin arrangement; the tamping platform trolley and the riprap trolley are arranged on two tracks respectively, occupying a large space on the main deck of the ship; the tamping platform trolley can only be connected to the fixed anti-trap on the side of the ship, and there is no safety protection function of rotating into the main deck surface; at the same time, the riprap device of the ship extends out of the side, and the method of mooring the riprap ship on its outside to feed the riprap hopper is complicated, the safety risk is increased, and it is also greatly affected by wind and waves, the effective operation time is short, and the efficiency is low. Utility Model Content

[0003] The purpose of the utility model is to provide a system for controlling the movement of a tamping integrated ship trolley to solve the problems raised in the above background technology. The design form that each trolley needs two winches to pull it to move left and right is broken, and a short track and tamping platform trolley are pulled into or out of the main deck as a whole by a winch, thereby improving the safety of the trolley. At the same time, the innovative application of follow-up control technology solves the control technology problems of similar equipment in the industry and fills the gap.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A system for controlling the movement of a tamping integrated ship trolley, characterized in that it comprises a C-type track, a short track, a first traction winch, a second traction winch and a pulley mechanism, wherein the C-type track and the short track are both located on the same side of the ship, the short track is connected to one end of the C-type track, the first traction winch is connected to the deck on one side of the short track, and the second traction winch is connected to the deck near the other end of the C-type track; the pulley mechanism comprises a single-disc pulley mechanism, a three-disc pulley mechanism and a guide pulley mechanism;

[0006] The guide pulley mechanism includes a first guide pulley of the tamping platform vehicle and a second guide pulley of the tamping platform vehicle, both of which are arranged at the bottom of the tamping platform vehicle truss, and the connecting line of the two coincides with the center line of the track;

[0007] The single cake pulley mechanism includes a first single cake pulley, a second single cake pulley, a third single cake pulley, and a fourth single cake pulley. The first single cake pulley and the second single cake pulley are sequentially connected downstream of the first traction winch. The third single cake pulley is located outside the short track, parallel to the two guiding pulleys of the ramming platform vehicle, and at the same height from the main deck. The fourth single cake pulley is located on the center line between the C-shaped track and the short track at a height lower than the two guiding pulleys of the ramming platform vehicle.

[0008] The three cake pulley mechanism includes a first three cake pulley group, a second three cake pulley group, and a third three cake pulley group. The first three cake pulley group is located downstream of the second single cake pulley. The second three cake pulley group and the third three cake pulley group are both horizontally arranged, and the lower pulleys of the pulley groups are at the same height from the main deck as the second single cake pulley.

[0009] The first single cake pulley is arranged perpendicular to the main deck surface along the wire rope direction, more than 5 m away from the first traction winch. The second single cake pulley is horizontally arranged, 3 m away from the first single cake pulley. The connecting line between the center line of the outer pulley groove of the second single cake pulley and the center line of the upper pulley groove of the first single cake pulley is horizontal with the main deck. The third single cake pulley is 4 m outside the short track. The included angle between the connecting line of the fourth single cake pulley and the second single cake pulley and the horizontal direction is less than 6°.

[0010] The follow-up technology is applied to the moving conditions of the stone throwing trolley or the ramming platform vehicle on the C-shaped track. The two conditions are front and back processes and do not move simultaneously. The first traction winch and the second traction winch are both driven by frequency conversion motors. In the follow-up mode, in the frequency conversion control cabinets of the first traction winch and the second traction winch, the brake brakes of the two winches are interlocked. The interlock control is that when the frequency conversion motor of the first traction winch is powered on, the brake of the first traction winch is powered on and disengaged, and at the same time, the brake of the second traction winch is also interlocked and powered on and disengaged. The first traction winch motor drives the winch to operate and tow the trolley to move, and at the same time, the cable of the second traction winch is passively towed and follows. The cable of the second traction winch is passively towed and follows, and its frequency conversion motor rotates following due to the external force transmission of the drum and the gearbox. The follow-up rotation of the second traction winch motor will generate regenerative electric energy, and energy consumption braking is carried out by installing a discharge resistance unit component on the DC side of the frequency converter. The energy consumption braking includes two parts: a braking unit and a braking resistor. The braking resistance offsets a part of the rotational inertia of the cable of the second traction winch being towed, preventing the drum of the second traction winch following from continuing to rotate and causing rope chaos when the first traction winch decelerates or stops. The principle of the second traction winch driving the cable to move the trolley and the first traction winch following is the same as above.

[0011] The follow-up control technology is brake interlock control. The control of the two traction winches includes separate local operation, remote single control, and remote linkage control.

[0012] A system for controlling the movement of the ramming and leveling integrated ship trolley of the present utility model breaks through the design deficiencies of the prior art. By innovatively utilizing the drive of two winches and the conversion of the cable system of the pulley mechanism, the movement of the ramming trolley and the stone throwing trolley on the same side track is realized. At the same time, only one winch is used to tow the short track and the ramming trolley to rotate in or out of the main deck as a whole, improving the safety of the ramming trolley. After optimizing multiple winches, the total power configuration of the ship is reduced, effectively saving the construction cost. Most importantly, by reducing the number and layout position of the trolleys, the working length of the track is increased, the construction distance of the trolley on the underwater foundation working section is improved, and the storage area of the surrounding material bin on the main deck of the ship is effectively increased, greatly improving the production efficiency and significantly saving the construction and maintenance costs. At the same time, the innovative application of the follow-up control technology solves the control technology problems of similar equipment in the industry and fills the gap.

The included angle between the connection line of the fourth single-pulley 18 and the second single-pulley 16 and the horizontal direction is less than 6°. Embodiment 2

[0027] This embodiment provides a method for the ram platform vehicle 1 to move.

[0028] In the middle of the lower bottom surface of the main steel structure frame of the ram platform vehicle 1, two pulleys are horizontally installed as the first guiding pulley 8 and the second guiding pulley 9 of the ram platform vehicle, which are respectively used for the cable systems of the first traction winch 5 and the second traction winch 6 to pull the ram platform vehicle 1 to move on the C-shaped track 3. Its function is to increase the pulling force multiple on the ram platform vehicle through the pulleys to overcome the sliding friction resistance of the ram platform vehicle, and at the same time serve as the traction point for pulling the ram platform vehicle to move. After the ram platform vehicle 1 is integrally moved onto the short track 4, the ram platform vehicle 1 is connected to the first traction winch 5 through the cable system. Under the traction of the first traction winch 5, the main steel structure frame of the ram platform vehicle 1 and the lower short track 4 rotate together with the steel bottom plate into the main deck of the ship. The bottom plate is connected to the bottom of the short track 4 and is fixed to the deck through the rotating shaft 7.

[0029] As Figure 3 shown, when the ram platform vehicle 1 rotates together with the short track 4 and rotates outwards from the inside to the outside, the cable connection relationship is as follows: the wire rope of the first traction winch 5 passes through the first single-pulley 15, the second single-pulley 16, the first three-pulley group 12, and the third three-pulley group 14, and then the rope end is fixed on the base of the first three-pulley group 12. When rotating inwards from the outside to the inside, the cable connection relationship is that the wire rope of the first traction winch 5 passes through the first single-pulley 15, the second single-pulley 16, the second three-pulley group 13, and the third three-pulley group 14, and then the rope end is fixed on the base of the second three-pulley group 13.

[0030] The No. 1 single-pulley sheave 15 is arranged perpendicular to the main deck surface along the direction of the steel wire rope, and is more than 5 m away from the No. 1 traction winch 5. Its function is to be unaffected by the change in the wire rope payout angle of the drum of the No. 1 traction winch 5, and always restrict and keep the passing steel wire rope in a parallel state; the No. 2 single-pulley sheave 16 is arranged horizontally, about 3 m away from the No. 1 single-pulley sheave 15. The connecting line between the center line of the outer groove of the No. 2 single-pulley sheave 16 and the center line of the upper groove of the No. 1 single-pulley sheave 15 is horizontal with respect to the main deck; the No. 2 triple-pulley sheave group 13 and the No. 3 triple-pulley sheave group 14 are both arranged horizontally, and the lower sheaves of the sheave groups are at the same height from the main deck as the No. 2 single-pulley sheave 16.

[0031] As Figure 4 shown, when the ramming platform vehicle 1 moves under the condition of the C-shaped track 3, after the ramming platform vehicle 1 rotates outwards together with the short track 4 from the inside, the track is locked, and the wire rope of the No. 1 traction winch 5 is disassembled and retracted; the cable connection relationship for the movement of the ramming platform vehicle 1 is: the wire rope of the No. 1 traction winch 5 passes through the No. 1 single-pulley sheave 15, the No. 2 single-pulley sheave 16, the No. 3 single-pulley sheave 17 and the No. 1 guiding sheave 8 of the ramming platform vehicle and is fixed on the No. 1 fixed cable lug 19; the wire rope of the No. 2 traction winch 6 directly passes through the No. 2 guiding sheave 9 of the ramming platform vehicle and is fixed on the No. 2 fixed cable lug 20.

[0032] The No. 1 guiding sheave 8 of the ramming platform vehicle and the No. 2 guiding sheave 9 of the ramming platform vehicle are both arranged at the bottom of the truss of the ramming platform vehicle 1, and the connecting line between the two coincides with the center line of the track; the No. 3 single-pulley sheave 17 is located 4 m outside the short track 4, is parallel to the No. 1 and No. 2 guiding sheaves of the ramming platform vehicle, and is at the same height from the main deck. Embodiment 3

[0033] This embodiment provides a method for the movement of the stone-throwing trolley 2.

[0034] As Figures 5 - 6 shown, when the stone-throwing trolley 2 moves under the condition of the C-shaped track 3, after the ramming platform vehicle 1 rotates outwards together with the short track 4 from the inside, the track is locked, and the wire rope of the winch is disassembled and retracted; the cable connection relationship for the movement of the stone-throwing trolley 2 is: the wire rope of the No. 1 traction winch 5 passes through the No. 1 single-pulley sheave 15, the No. 2 single-pulley sheave 16, the No. 3 single-pulley sheave 17, and then passes through the bottom of the ramming platform vehicle 1 and is directly connected to the No. 1 fixed eye plate 10 of the stone-throwing trolley 2; the wire rope of the No. 2 traction winch 6 is directly connected to the No. 2 fixed eye plate 11 of the stone-throwing trolley 2;

[0035] When the stone-throwing trolley 2 moves under the condition of the C-shaped track 3, after the ramming platform trolley 1 rotates inward from outside to inside together with the short track 4, the short track is locked, and the steel wire rope of the first traction winch is disassembled and retracted; the cable connection relationship for the movement of the stone-throwing trolley 2 is as follows: the steel wire rope of the first traction winch 5 passes through the first single-sheave pulley 15 and the second single-sheave pulley 16, passes through the gap between the short track 4 and the C-shaped track 3, and is directly connected to the first fixed eye plate 10 of the stone-throwing trolley 2 after passing through the fourth single-sheave pulley 18; the steel wire rope of the second traction winch 6 is directly connected to the second fixed eye plate 11 of the stone-throwing trolley 2.

[0036] The described fourth single-sheave pulley 18 is located on the center line between the tracks at the connection of the C-shaped track 3 and the short track 4, and its height is lower than the first and second guiding pulleys of the ramming platform trolley, so as to prevent the ramming platform trolley 1 from being restricted during movement; the included angle between the connection line of the fourth single-sheave pulley 18 and the second single-sheave pulley 16 and the horizontal direction is less than 6°. Embodiment 4

[0037] The follow-up control adopted in Embodiment 1 and Embodiment 2 specifically adopts the following method:

[0038] When the stone-throwing trolley 1 or the ramming platform trolley 2 moves on the C-shaped track 3, the follow-up technology is applied. These two working conditions are sequential processes and do not move simultaneously; the first traction winch 5 and the second traction winch 6 are both driven by frequency conversion motors. In the follow-up mode, in the frequency conversion control cabinets of the first traction winch 5 and the second traction winch 6, the brake brakes of the two winches are interlocked and controlled; the interlocked control is that when the frequency conversion motor of the first traction winch 5 is powered on, the brake of the first traction winch 5 is powered on and disengaged, and at the same time, the brake of the second traction winch 6 is also interlocked and powered on and disengaged; the motor of the first traction winch 5 drives the winch to operate and pull the trolley to move, and at the same time, the cable of the second traction winch 6 is passively pulled and follows; for the cable of the second traction winch 6 being passively pulled and following, its frequency conversion motor rotates following due to the external force transmission of the drum and the gearbox. The follow-up rotation of the motor of the second traction winch 6 will generate regenerative electric energy, and energy consumption braking is carried out by installing a discharge resistance unit component on the DC side of the frequency converter; the energy consumption braking includes two parts: a braking unit and a braking resistor. The braking resistance offsets a part of the rotational inertia of the cable of the second traction winch 6 being pulled, preventing the drum of the second traction winch 6 that follows from continuing to rotate and causing rope entanglement when the first traction winch 5 decelerates or stops; the principle of the second traction winch 6 driving the cable to move the trolley and the first traction winch 5 following is the same as above.

[0039] The follow-up control technology is the interlocked control of the brakes. The control of the two traction winches includes individual local operation, remote single control, and remote linkage control.
