Description

Technical Field

[0001] The utility model relates to the technical field of vertical lifting ship machinery, in particular to a large-scale flat-plate gate inflation and water-stopping efficient replacement device. Background Art

[0002] An inflatable water-stop device is arranged on the water-facing surface downstream of the Three Gorges Shiplift Flat Gate. When the water-stop rubber in the inflatable water-stop device reaches its service life or is damaged and leaking, the gate needs to be lifted out of the gate slot to the locking position and locked for water-stop replacement. At this time, the gate is in a suspended parking state, with the bottom water-stop range completely suspended and the side water-stop range suspended within 10m above the ground.

[0003] Affected by the structural size and weight of the inflatable waterstop itself, its conventional replacement methods are mainly the following: Replacement method 1: Use the full-chamber rack construction from the bottom plate of the channel at the bottom of the portal body. This method has the outstanding characteristics of large construction platform construction volume, long construction period, high cost, and high safety risk. Replacement method 2: The bottom waterstop replacement adopts the welding arrangement of the bracket construction platform at the bottom of the portal body, and the side waterstop adopts the single-row rack construction method. In this way, the construction platform of the bottom waterstop requires 2 cranes to cooperate with the platform welding and disassembly on the portal body. Due to space constraints, the side waterstop can only be built with a single row of racks. The layout process involves welding and cutting of the portal structure and the cooperation of double cranes. The construction platform has the outstanding characteristics of complex construction, long construction period, high cost, and high safety risk.

[0004] Chinese patent document CN112030926A, publication / announcement date: 2020.12.04, discloses an efficient disassembly and assembly device for pressurized water-stop of large flat gate of vertical ship lift, in which the pressurized water-stop side water-stop 3 on the flat working gate 1 is disassembled and installed through the pressurized water-stop side water-stop replacement platform 5. During operation, in order to facilitate the disassembly and installation of the pressurized water-stop side water-stop 3, the pressurized water-stop side water-stop replacement platform 5 is arranged in front of the pressurized water-stop side water-stop 3. When the pressurized water-stop side water-stop 3 is removed and hoisted out, or the new pressurized water-stop side water-stop 3 is hoisted, the pressurized water-stop side water-stop 3 can only pass through the gap between the pressurized water-stop side water-stop replacement platform 5 and the flat working gate 1, which is inconvenient to lift.

DETAILED DESCRIPTION

[0027] See also Figure 1-8 A high-efficiency replacement device for a large flat-plate gate inflatable water-stop, comprising two sets of side water-stop replacement platforms 5 for replacing the pressurized side water-stops 3 on both sides of the flat-plate gate 1, and a bottom water-stop replacement platform 6 located below the flat-plate gate 1 for replacing the pressurized bottom water-stop 4. The two sets of side water-stop replacement platforms 5 are left-right symmetrical structures. The side water-stop replacement platforms 5 include a channel frame steel structure 51 and an operating frame steel structure 52. The operating frame steel structure 52 is fixedly connected to one side of the channel frame steel structure 51. A plurality of operating platforms 53 are arranged at intervals in the upper and lower parts of the operating frame steel structure 52. The operating platform 53 is movably installed with a protruding platform 54 at one end close to the pressurized side water-stop 3.

[0028] By arranging multiple working platforms 53 at upper and lower intervals in the working frame steel structure 52, an extension platform 54 is movably installed at one end of the working platform 53 close to the pressurized side water-stop 3. When the pressurized side water-stop 3 needs to be disassembled and installed, the extension platform 54 is extended, and personnel can stand on the extension platform 54 to install the pressurized side water-stop 3. When the pressurized side water-stop 3 needs to be lifted, the extension platform 54 is folded, and the lifting is more convenient.

[0029] For details, see Figure 2-5 The channel frame steel structure 51 includes side frames 511 and cross bars 512 on both sides. The front and rear sides of the side frames 511 on both sides are connected as a whole by multiple cross bars 512. A channel for people to climb up and down is formed between the side frames 511 on the left and right sides and the cross bars 512 on the front and rear sides. The channel for people to climb up and down is connected to the working platform 53. Through the above structure, multiple cross bars 512 form a ladder structure, which is convenient for workers to enter the working platform 53 through the frame steel structure 51.

[0030] See also Figure 3 At least two connecting rods 57 are fixedly connected to the top of the side water stop replacement platform 5 on the side close to the flat gate 1. It is convenient for the side water stop replacement platform 5 to be installed and fixed with the flat gate 1. When in use, the connecting rod 57 is installed on the top of the flat gate 1 by bolts.

[0031] Further, referring to Figures 2 and 3, two handrails 56 are fixedly connected to the left and right sides of the top of the channel frame steel structure 51. The handrails 56 are formed by bending round tubes and welded to the left and right sides of the top of the channel frame steel structure 51 to facilitate operators to enter the channel of the frame steel structure 51.

[0032] In a preferred embodiment, see Figure 4-6 , the working frame steel structure 52 is provided with two hinge shafts 55 on the side close to the pressurized side water stop 3 and above the working platform 53, and one end of the extension platform 54 is hinged on the two hinge shafts 55, so that the extension platform 54 can be folded onto the working platform 53, or turned over and extended from the working platform 53. The extension platform 54 is hinged to the working frame steel structure 52 through the two hinge shafts 55. When the pressurized side water stop 3 needs to be disassembled and installed, the extension platform 54 is turned over and extended, and personnel can stand on the extension platform 54 to install the pressurized side water stop 3. When the pressurized side water stop 3 needs to be hoisted, the extension platform 54 is turned over and folded onto the working platform 53.

[0033] For clarification, see Figure 6 In order to limit the position of the extension platform 54 when it is turned over and extended, the hinge shaft 55 needs to be as far away from the right edge of the working frame steel structure 52 as possible. In this way, when the extension platform 54 is turned over and extended, the extension platform 54 can be limited by the hinge shaft 55 and the right edge of the working platform 53. More specifically, combined with Figure 5 When the extension platform 54 is unfolded, the left end of the extension platform 54 is limited by the hinge shaft 55, and the lower side of the extension platform 54 abuts against the right edge of the working platform 53, so that the extension platform 54 will not rotate further downward. In order to facilitate the rotation of the extension platform 54, a fillet centered on the hinge shaft 55 is set at one end of the extension platform 54 connected to the hinge shaft 55.

[0034] In addition, in addition to the above-mentioned structure, the extension platform 54 can also be extended by setting two horizontal slide grooves on the upper side of the working platform 53 in the working frame steel structure 52, and the extension platform 54 can be translated, slid and retracted through the slide grooves on the left and right sides.

[0035] See also Figure 1 , 7 8. The bottom water stop replacement platform 6 includes a top steel frame 61 and a lower steel basket 62. The lower steel basket 62 is fixedly connected to the lower side of the top steel frame 61, and the length of the lower steel basket 62 is less than the length of the top steel frame 61, so that the two ends of the top steel frame 61 form extended ears 63. Through the above structure, when in use, the ears 63 on both sides are placed on the concrete base 7 on both sides below the flat gate 1. The steel basket is similar to a hanging basket structure, and personnel stand in the lower steel basket 62, which provides sufficient activity space for operators to replace water stops.

[0036] Furthermore, a hot vulcanizer bearing base 64 is provided in the middle of the lower steel structure basket 62, and the hot vulcanizer bearing base 64 is used to place the hot vulcanizer. The water-stop rubber has a joint in the middle of the lower side of the flat gate 1, and the two sections of the water-stop rubber are vulcanized and connected into a whole by the hot vulcanizer.

[0037] Furthermore, the top steel frame 61 is provided with a placement platform 65 on one side close to the flat gate 1. Specifically, the placement platform 65 is a long strip of steel plate welded on the top steel frame 61 for spreading and placing the bottom water stop and the pressure plate.

[0038] The working principle or use process of the utility model is as follows:

[0039] See also Figure 1 When replacing the water stop, lift the flat gate 1 out of the gate slot to the top of the gate body locking support beam 2. Then hoist the bottom water stop replacement platform 6 to the bottom of the flat gate 1, and the ears 63 on both sides of the bottom water stop replacement platform 6 are placed on the concrete base 7 on both sides below the flat gate 1. When placing the bottom water stop replacement platform 6, the bottom water stop replacement platform 6 is close to the flat gate 1, which is convenient for disassembly and installation operations.

[0040] Then, the side water-stop replacement platforms 5 on both sides are hoisted in sequence. First, the side water-stop replacement platform 5 is hoisted against the flat gate 1, and then the connecting rod 57 is installed on the top of the flat gate 1 by bolts, so as to stabilize the side water-stop replacement platform 5. In this way, the pressurized side water-stop 3 is replaced by the side water-stop replacement platform 5, and the pressurized bottom water-stop 4 is replaced by the bottom water-stop replacement platform 6. When the pressurized water-stop side water-stop 3 needs to be disassembled and installed, the extension platform 54 is extended, and personnel can stand on the extension platform 54 to install the pressurized water-stop side water-stop 3. When the pressurized water-stop side water-stop 3 needs to be hoisted, the extension platform 54 is retracted.
