Description
Technical Field
The invention relates to gate installation in hydraulic engineering, in particular to a device for bidirectional small-stroke adjustment in the bottom shaft installation process of a bottom shaft driven turning plate type steel gate.
Background
In recent years, bottom shaft driven turning plate type steel gates are increasingly used in hydraulic engineering river channel improvement pump gate projects. In the installation engineering of the bottom shaft driving turnover plate type steel gate, after the construction of a gate chamber bottom plate and a gate pier retaining wall is finished, the steel gate is installed, the bottom shaft is generally installed firstly, then a gate leaf structure is installed on the bottom shaft, and the bottom shaft is connected with a hydraulic hoist through a wall penetrating sleeve and a support arm. In the running process of the gate, the hydraulic hoist drives the bottom shaft to drive the gate leaf to turn over, so that the aim of regulating and controlling the water level is fulfilled.
When the bottom shaft is installed, the bottom shaft is firstly hung to the bottom plate surface of the brake chamber to be installed in a sectionalized mode through hanging, and after the bottom shaft is spliced into a whole on site manually, the bottom shaft precision is adjusted and positioned. Due to the influence of structural characteristics, errors generated by bottom shaft installation can be amplified at two side edges of the gate leaf, so that the relative errors between the gate leaf and the water-stop faced steel plate are increased, and once the design requirements cannot be met, the defects of water leakage, unstable operation, gate shake, abnormal sound and the like are easily generated in the operation process of the gate, and normal use is influenced. Since such defects cannot be eliminated by subsequent maintenance, they have a great impact on both the engineering quality and the service life of the gate. Therefore, the precision requirement of the installation of the bottom shaft is high, and the error range of the general design requirement is within 3 mm.
When the bottom shaft is adjusted and positioned, the bottom of the bottom shaft is generally 200-300 mm away from the bottom plate surface of the sluice chamber, and the distance is only 206mm for a 6m sluice. Since the overall height of conventional jacks generally exceeds this dimension, the jack cannot be placed directly below the bottom shaft on the chamber floor plane for adjustment of the elevation direction. Meanwhile, the whole weight of the bottom shaft of the 6m gate is generally about 5 tons, so that the bottom shaft is difficult to adjust in the horizontal direction.
In the prior art, the spliced bottom shaft is firstly hoisted and placed on two H200 multiplied by 8 multiplied by 12 section steel with the length of about 500mm, lifting jacks are adopted in hoist chambers at two sides of a lock chamber to respectively support two ends of the bottom shaft for adjusting the elevation direction, and after one end of the bottom shaft is initially lifted in place, the bottom shaft and a reserved dowel bar of the lock pier are firstly fixed by spot welding, and then the other end of the bottom shaft is adjusted. And after the elevation directions of the two ends are adjusted in place, carrying out rechecking on the elevation directions, if the elevation has errors, repeating the process until the accuracy of the elevation directions meets the requirement, supporting the bottom of the bottom shaft by adopting H200 section steel and a cushion block, and then carrying out adjustment on the horizontal direction. When the horizontal direction is adjusted, the horizontal deviation of the axis is measured firstly, the side of the jack is placed on the gate pier wall at the side needing to be adjusted, the side edge of the jack is propped, and the bottom shaft is pushed to the designed position. After the horizontal positions of the two sides of the bottom shaft are adjusted, the axial position of the bottom shaft is rechecked. If the deviation exists, the above process is repeated.
The above method has the following defects: 1. because the equipment installation platform is required to be reserved in the hoist chamber, the basal plane is generally lower than the bottom of the bottom shaft by more than 600mm, and when the elevation adjustment is carried out, the jacking height of one jack is insufficient, so that the jack can be jacked by only 2 jacks in relay mode, and because the operation space is small, the two jacks can be jacked by relay mode, so that great potential safety hazards exist. 2. The adjustment of the elevation direction and the horizontal direction of the bottom shaft can generate mutual interference influence, the bottom shaft cannot be in place at one time, and the installation speed is greatly related to the experience and the level of an installer. 3. The installation process is slow, the error control difficulty is high, and the adjustment is generally required to be carried out for at least 3 times. 4. The installation operation environment is limited, the elevation direction needs 2 jack relay thrusts, the horizontal direction needs to adjust the jack position to perform lateral thrusts, the labor intensity of construction operators is high, and the safety is poor.
Therefore, there is a need for an adjustment mounting device that can be used between the bottom of the bottom shaft and the bottom plate surface of the brake chamber, and that can perform bidirectional adjustment in the elevation direction and the horizontal direction of the bottom shaft, so as to solve the above-mentioned problems.
