Abstract
The utility model discloses an ultra-large down-the-hole arc-shaped water gate which comprises an arc-shaped gate and a gate wall, wherein the arc-shaped gate is composed of a gate flap, inclined supporting arms and supporting hinges; a set of main cross beams, of which the quantity is not less than four, are arranged on the gate flap from top to bottom; each of the main cross beams is respectively in rigid connection with two inclined supporting arms which are symmetrical to each other on left and right sides, so as to form a main cross beam inclined supporting arm frame structure; the inclined supporting arms are divided into two sets which are symmetrical to each other on the left and right sides; the rear ends of the inclined supporting arms in each set are all connected with two brackets fixed on the gate wall through the supporting hinges; and more than two lifting lugs are arranged at the top of the gate flap of the arc-shaped gate. Multiple main cross beam inclined supporting arm frame structures are adopted by the ultra-large down-the-hole arc-shaped water gate and are used for reducing the loads distributed to each of the main cross beams and the supporting arms, so as to overcome the difficulties in manufacturing, welding, transporting and mounting the gate and to reduce the difficulties in manufacturing, transporting and mounting a hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of water conservancy and hydropower building sluicing facility, especially a kind of ultra-large type down-the-hole arc sluice.
Background technology
At present, in sluice, down-the-hole arc sluice adopts the two main beam allotment arm frame construction patterns of single suspension centre more.Along with the development of science and technology, the scale of down-the-hole arc sluice is increasing, and area is near 200m
2Swing type hydraulic machine list suspension centre capacity has reached 7500kN, by traditional down-the-hole arc sluice pattern design, the headstock gear capacity will exceed present existing technical level, and the sectional dimension of gate girder and support arm is large, cause gate manufacturing, welding, transportation and difficulty is installed, become the bottleneck of its development of restriction, secondly, civil engineering must arrange the concrete continuous beam of supporting arc door behind the lock wall, invest also larger.
Summary of the invention
The purpose of this utility model is: a kind of ultra-large type down-the-hole arc sluice is provided, and it can reduce manufacturing, welding, transportation, the installation and maintenance difficulty of Segment gate and corresponding opening and closing device, saves the investment of civil engineering concrete, to overcome the deficiencies in the prior art.
The utility model is achieved in that ultra-large type down-the-hole arc sluice, comprises Segment gate, the lock wall, and Segment gate is comprised of gate flap, oblique support arm and a hinge; Gate flap is comprised of one group of main beam, panel, secondary crossbeam and longeron; Tiltedly support arm is divided into symmetrical two groups, and the front end of two groups of oblique support arms all rigidly connects with main beam and forms one group of oblique support arm framework of main beam, the rear end of two groups of oblique support arms all by prop up cut with scissors respectively be fixed on the lock wall on two brackets be connected; Gate flap top at Segment gate is provided with plural hanger.
Hanger and two groups of oblique support arms all relatively the lock centerline hole be arranged symmetrically with.
The quantity of main beam and every group of oblique support arm equates, and main beam and every group of oblique support arm quantity are more than 4.
Owing to adopting above-mentioned technical scheme, compared with prior art, the utility model adopts the oblique support arm frame construction of many main beams, reduce the load that is assigned to every girder and support arm by the oblique support arm frame construction of many main beams pattern, with the difficulty of the manufacturing, welding, transportation and the installation that solve gate; And the many suspension centres of gate locating, each suspension centre is connected with the head that hangs of multi-cylinder swing type hydraulic machine, has reduced the keying capacity of single cylinder swing type hydraulic machine, to solve the difficulty of hydraulic cylinder manufacturing, transportation and installation; The center of circle of the center of rotation of gate and arc upstream face coincides, make the total water pressure that acts on the arc upstream face always by a center of rotation of hinge, to reduce force of opening and closing, current can reduce current to the impact of both sides lock wall by the Segment gate upstream face during sluicing; Gate adopts oblique support arm, greatly reduces a hinge center to the distance of lock wall, and civil engineering only arranges bracket at the lock wall and gets final product the supporting arc door, need not to arrange continuous beam, has effectively saved construction investment.The utility model is simple in structure, and is with low cost, and result of use is desirable.
