Detailed Description
The following describes embodiments of the present invention in detail with reference to the drawings, which are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are provided, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-8, since the gate hole in this embodiment has a width of 9.0m and a height of 8.0m, a designed water head of 19m, and a designed water head of 9.43m at the downstream, the double-hanging-point inverted hydraulic hoist of the present invention is used to operate a down-the-hole working gate structure, so as to reduce the installation height of the frame, reduce higher equipment protruding out of the dam face, improve the landscape coefficient of the dam face, and facilitate the daily maintenance work of the dam.
Specifically, the invention comprises a pair of racks 1 arranged on the top of the dam, and each rack 1 is provided with a reverse hanging type hydraulic hoist 2 positioned in a dam body installation cavity. The piston rod of the hydraulic hoist 2 is connected with the frame 1, and the cylinder body of the hydraulic hoist 2 is connected with the top of the door body 3. When the gate is in a closed water retaining state, the door body 3 is located in the door groove, a bottom sill 4.1 is arranged at the bottom of the door groove, a vertical main rail 4.2 and a vertical reverse rail 4.3 are correspondingly arranged on the front side and the rear side of the door groove respectively, a main wheel 3.1, a side guide wheel 3.2 and a reverse sliding block 3.3 which are matched with the main rail 4.2 and the reverse rail 4.3 are arranged on the door body 3, and further, in order to seal the gate, main water stop 3.4 (comprising bottom water stop, side water stop and top water stop) is further arranged on the door body 3. When the door body 3 is in a closing water retaining state, the bottom water is compressed by the self weight of the gate, and the side water and the top water are retained by prepressing, adding water and pressing. However, in the process of closing the door by moving water, the main water stop 3.4 is separated from the water stop seat on the door lintel, so that the water jet phenomenon occurs, and the gate is vibrated. In order to avoid the phenomenon, a water-jet-proof water-stop 3.5 matched with the door body 3 is arranged on the breast wall of the door slot. Because the water-jet-proof seal 3.5 is fixed on the chest wall, the position of the water-jet-proof seal can not be changed along with the opening and closing of the gate, when the working gate is opened and closed and the local opening controls the leakage, the water-jet-proof seal 3.5 is always attached to the door body 3, and the water jet at the position and the gate vibration caused by the water jet can be effectively prevented. Meanwhile, the piston rod of the double-lifting-point hydraulic hoist 2 is rigidly hinged with the lifting lug of the door body 3, so that the vertical creeping vibration of the gate is avoided, and the gate is favorable for starting and stopping the moving water.
Under the normal condition, when the gate is subjected to water stop inspection and replacement and door body anticorrosion treatment, the inverted hydraulic hoist and the related frame need to be detached through hoisting equipment, and then the door body is hoisted to the top of the dam, so that the time and the labor are wasted. Therefore, the maintenance platform 5 positioned above the gate slot is additionally arranged in the dam body installation cavity, when in maintenance, the inspection and replacement, the anticorrosion treatment and the like of the water stop of the door body can be carried out only by lifting the door body 3 to a position 0.5m above the maintenance platform 5 by the aid of the inverted hydraulic hoist 2, and maintenance efficiency is greatly improved.
When overhauing the door body 3, in order to provide great overhaul space for change main wheel 3.1 etc. still install along vertical setting's activity main rail 6.1 and activity anti rail 6.2 on overhauing platform 5, above-mentioned activity main rail 6.1 and main track 4.2 position are corresponding, and activity anti rail 6.2 and anti rail 4.3 position are corresponding. During installation, the lower part of the movable main rail 6.1 is connected with the top of the main rail 4.2 and the embedded part 6.3 connected with the lower part of the movable main rail through the internode bolt 6.4, the side surface of the movable main rail 6.1 is connected with the embedded part 6.5 which is embedded in the gate pier in the positive direction of the movable main rail through the internode bolt, and then the gap is adjusted through epoxy mortar, so that the installation accuracy of the movable main rail 6.1 is ensured. The movable counter rail 6.2 is installed with the movable main rail 6.1, and a pedestrian passageway 6.6 is further formed in the middle web plate of the movable counter rail 6.2. In addition, a hand-operated telescopic locking device 7 positioned on the left side or the right side of the door body 3 is installed on the maintenance platform 5 and used for fixing the position of the lifted door body 3.
In the invention, a mounting platform 8 close to the top of the dam body is also arranged in the dam body mounting cavity, a hydraulic pump station 9 connected with the hydraulic hoist 2 is arranged on the mounting platform, and the hydraulic pump station 9 comprises an electro-hydraulic proportional automatic deviation correcting mechanism with the precision controllable within +/-2 mm and is used for solving the synchronous problem of opening and closing of the double lifting points of the door body 3. In this embodiment, the initial point of the hydraulic hoist 2 is set in the state where the working gate is closed, so that the initial position of the door opening is in a completely synchronous state, and only automatic deviation correction is performed in the door opening process.
In consideration of the problems of equipment installation, scrapping, secondary lifting installation of updated equipment and the like, the gantry crane rotary crane 10 for overhauling is installed on the dam crest, so that the field installation is facilitated, and the installation cost is saved.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
