Abstract
The invention discloses a method for opening and closing a cable-stayed arc-shaped gate by using a hydraulic hoister. Hoisting heads at two ends of the hydraulic hoister are respectively provided with a cross-shaped hinge joint, two hinged shafts of the cross-shaped hinge joints are mutually vertical, the hydraulic hoister is respectively connected with an arc-shaped gate hoisting lug and an upper support of the hydraulic hoister through the two cross-shaped hinge joints; the arc-shaped gate hoisting lug can be arranged at the optimal force bearing position of the arc-shaped gate on the basis of reducing a force loading arm of a cantilever as far as possible, and the axial line of the hoisting lug of the arc-shaped gate is ensured to be vertical to a longitudinal symmetrical center plane of the arc-shaped gate, thus the arc-shaped gate can be opened and closed; and the support of the hydraulic hoister is arranged in the optimal suspension length on the basis of reducing a bending moment internal force of a cantilever section, so as to keep the axial line of the hinged shafts of the upper support of the hydraulic hoister to be vertical to the longitudinal symmetrical center plane of the arc-shaped gate. Overcoming the conflicts of the upper hoisting point and the lower hoisting point of the hydraulic hoister in arrangement positions during the arrangement of large-orifice and large-span arc-shaped gates, the manufacturing and installation cost of the arc-shaped gate is saved.
Description
Technical field
The present invention relates to Segment gate method for opening and closing in the hydraulic engineering, especially relate to the oblique arcing shape gate of hydraulic hoist method for opening and closing.
Background technology
In the design of hydraulic engineering metal construction, Segment gate opens and closes the normal hydraulic hoist that adopts.As Fig. 5, shown in Figure 6, the hanger of gate often adopts cylinder hinge and headstock gear to hang head to be connected, and the headstock gear other end links to each other with cylinder bearing on being fixed on the gate pier side wall.According to Segment gate constraints, obviously in the gate opening/closing process, the headstock gear central axis must with the vertical symmetrical centre plane parallel of gate.Therefore, the position of upper and lower two suspension centres of headstock gear is the contradiction that gate is arranged always.One, aspect the gate structure stress condition, following suspension centre is near more apart from the support arm fulcrum, and the structure stress condition of gate beam is good more, because the acting force arm of semi girder load is short, the moment of flexure internal force of crossbeam is just little, can save material.Its two, the braced structures of headstock gear upper bracket stressed aspect, the vertical symmetrical centre of pivot distance gate plane is near more, the cantilever segment of fulcrum embedded part is just long more, the moment of flexure internal force of this section is just big, causes waste of material.For big aperture particularly the Segment gate of large span arrange that this contradiction is particularly outstanding.Therefore, how adopting simple method to solve above-mentioned contradiction, is the problem that those skilled in the art study always, but yet there are no the report of all relevant this respects.
Summary of the invention
The object of the invention is to provide the oblique arcing shape gate of a kind of simple hydraulic hoist method for opening and closing.
For achieving the above object, the present invention can take following technical proposals:
The oblique arcing shape gate of hydraulic hoist of the present invention method for opening and closing, hanging of hydraulic hoist two ends a cross articulated joint is installed respectively on the head, two hinges of described cross articulated joint are vertical mutually, and hydraulic hoist is connected with the hanger of Segment gate and the upper bracket of hydraulic hoist respectively by described two cross articulated joints;
The hanger of Segment gate can be arranged in the stressed position of Segment gate the best, is as the criterion with the arm of force that reduces overhung load as far as possible, as long as keep the hanger axis of Segment gate vertical with the vertical symmetrical centre of Segment gate plane;
The hydraulic hoist upper bracket is arranged as far as possible and is approached gate pier side wall position, that is: as far as possible away from the vertical symmetrical centre of Segment gate plane, be as the criterion with the moment of flexure internal force that reduces cantilever segment, as long as keep the hinge axis of hydraulic hoist upper bracket vertical with the vertical symmetrical centre of Segment gate plane.
Advantage of the present invention just is at big aperture, when the large span Segment gate is arranged, the contradiction that upper and lower two suspension centres of hydraulic hoist exist on position is hung head by described cross articulated joint with the hydraulic hoist two ends and is hinged with Segment gate hanger, gate pier side wall headstock gear bearing respectively; Because two hinges of cross articulated joint are vertical mutually, satisfy the constraint consistency condition of how much motions of gate system, therefore, the hanger of Segment gate can be arranged in best stressed active position as far as possible, and be not subjected to the restriction of headstock gear upper bracket position, to shorten the acting force arm of gate semi girder load, reduce the moment of flexure internal force of Segment gate crossbeam; Simultaneously, the hydraulic hoist upper bracket also can be arranged the best length of hanging as far as possible, is not subjected to a restriction of body hanger position, to reduce the moment of flexure internal force of bearing cantilever segment.Like this, Segment gate because the two-way rotary action of cross articulated joint satisfies how much kinematic constraint conditions of total system, has solved above-mentioned contradiction well in opening-closing process, saved manufacturing, the installation cost of Segment gate.Because the hydraulic hoist central axis no longer needs to keep and the vertical symmetrical centre plane parallel of gate, but allows to present an angle, therefore be referred to as tiltedly to draw.

The specific embodiment
Shown in Fig. 1-4, the oblique arcing shape gate of hydraulic hoist of the present invention method for opening and closing, take a cross articulated joint 2 respectively to be installed on the head hanging of hydraulic hoist 1 two ends, two hinges 3,4 of described cross articulated joint 2 are vertical mutually, and hydraulic hoist 1 is connected with the hanger 8 of Segment gate 5 and the upper bracket 9 of hydraulic hoist 1 respectively by described two cross articulated joints 2; The hanger 8 of Segment gate 5 can be arranged in the optimum position of Segment gate 5, is as the criterion with the arm of force that reduces overhung load as far as possible, as long as keep hanger 8 axis of Segment gate 5 vertical with the vertical symmetrical centre of Segment gate plane 6; Hydraulic hoist 1 upper bracket 9 also can be arranged as far as possible and approach gate pier side wall 7 positions, the moment of flexure internal force that hang length to reach best, reduces cantilever segment is as the criterion, as long as keep the hinge axis of hydraulic hoist 1 upper bracket 9 vertical with the vertical symmetrical centre of Segment gate plane 6.
