Abstract
The utility model discloses a miter gate with a bottom pivot at the top of the gate, which comprises a gate flap and a top crossbeam arranged on the gate flap. One end of the top crossbeam is provided with an extended section longer than the gate flap; the bottom pivot is arranged below the extended section; and a pillow seat is arranged at the top of the extended section. In the utility model, the bottom pivot is arranged at the top of the miter gate; the severe working environment in which the conventional bottom pivots are immersed in water is completely changed; the miter gate with the bottom pivot at the top of the gate is simpler than the common miter gates in design, manufacture, mounting, running and maintenance, has better use performances, is particularly suitable to be used in medium and small ship lock construction projects and has wide application foreground.
Description
Technical field
The utility model relates to a kind of miter gate, belongs to water conservancy gate engineering foundation construction technique field, is specifically related to the miter gate of pivot of a kind of end on the door top.
Background technology
Along with the continuous growth of demands such as China's urban water use, the construction of view ship lock, environmental renovation, various water conservancy gates have obtained using widely.Particularly in ship lock is built, miter gate with its reasonable structural arrangement, advantages such as flexible operation is reliable, hoisting capacity is little, material saving, become most widely used a kind of type in various other ship lock of level.
Miter gate is made up of two gate flaves, and around the vertical axis rotary opening and closing of its end, when gate flap was positioned at closed condition, it supported mutually along the mitered suture of two gate flaves, overlooks and sees the gate plan view, forms " people " font pattern.In the miter gate structure, the most complicated part of structure is top pivot and end pivot, and during gate opening/closing, gate flap is around the theoretical line axle rotation of top pivot and end pivot center of rotation.Routine is that end pivot is arranged in the bottom rotating shaft of miter gate in the heart, because end pivot is immersed in the water all the year round, condition of work is abominable, in case damage, gate just can not turn round, and change or repair end pivot, the water in the lock chamber must be drained only, with the gate dismounting, waste time and energy, be very much difficulty.
The utility model content
Goal of the invention: at the deficiency that existing miter gate exists, the purpose of this utility model provides the miter gate of pivot of a kind of end on the door top, with the thorough working environment that improves end pivot, makes at ordinary times maintenance, easy to lubricate, increases the reliability of gate work.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is:
Pivot of a kind of end is at the miter gate on door top, comprises gate flap and is arranged on head piece on the gate flap, is provided with the extension that exceeds gate flap length at an end of described head piece, is provided with end pivot below the extension.
On the side of described gate flap framework lower end, be provided with adjustable hinge.
At least also being provided with 1 bolster seat between pivot of the described end and adjustable hinge links to each other with gate flap.Preferably be provided with 2, crossbeam first-selected and on the gate flap links to each other.Top in the extension can be provided with the bolster seat equally.
Described head piece is provided with and is used for the crossette that links to each other with hydraulic hoist.
The end of the present utility model pivot is at the miter gate on door top, gate flap is made up of girder steel framework and outside weld panel, is provided with some crossbeams on gate flap, and the top of gate flap is head piece, in axis of rotation one side, head piece length exceeds gate flap length, exceeds part and is the extension, on the top of extension the bolster seat has been installed, be used to bear the horizontal supporting counter-force of head piece when closing state, and it is passed to reinforced concrete foundation, the following end pivot of then having installed of extension is used for the weight of grantee's word strobe.Below the gate flap framework, be provided with an adjustable hinge, its center line can be adjusted to consistent with end pivot center line, in order to the rotation gate flap.In each beam top of the centre of gate flap framework, the bolster seat has been installed equally, be used to bear the horizontal supporting counter-force of crossbeam when closing state, and it is passed to reinforced concrete foundation.Correct position at the gate head piece also is installed with crossette, is used for linking to each other with hydraulic hoist.
The utility model is the improvement to existing miter gate structure.At the lock top of miter gate two sides correct position, hydraulic hoist is installed, the piston rod hanger in its oil cylinder links to each other with crossette.When hydraulic hoist piston rod moving linearly, miter gate is just swung along the rotation centerline of end pivot and adjustable hinge, reaches the purpose that Qi Menhe closes door.
Beneficial effect: the utility model is arranged on end pivot at the top of miter gate, thoroughly having changed pivot of original end is immersed in the abominable working environment in the water all the year round, all simple from design, manufacturing, installation and operation, maintenance aspect than ordinary people word strobe, and functional performance is better, suit especially in middle-size and small-size ship lock construction project, to use, have a extensive future.
Description of drawings
Fig. 1 is the structural representation of the end of the present utility model pivot at the miter gate on door top.
Fig. 2 is the vertical view of the end of the present utility model pivot at the miter gate on door top.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained.
As depicted in figs. 1 and 2, be the miter gate of the end of the present utility model pivot on the door top.This end pivot is at the miter gate on door top, comprises gate flap 1 and is arranged on head piece 2 on the gate flap 1, is provided with the extension that exceeds gate flap 1 length at an end of head piece 2, is provided with end pivot 4 below the extension, is provided with bolster seat 3 on the top of extension.On gate flap 1 framework lower end side, be provided with adjustable hinge 5.At least also being provided with 1 bolster seat 3 between end pivot 4 and adjustable hinge 5 links to each other with gate flap 1.Preferably be provided with 2, crossbeam first-selected and on the gate flap 1 links to each other.Head piece 2 is provided with and is used for the crossette 6 that links to each other with hydraulic hoist.
The end of the present utility model pivot is at the miter gate on door top, gate flap 1 is made up of girder steel framework and outside weld panel, on gate flap 1, be provided with some crossbeams, the top of gate flap is head piece 2, in axis of rotation one side, head piece 2 length exceed gate flap length, exceed part and be the extension, on the top of extension bolster seat 3 has been installed, be used to bear the horizontal supporting counter-force of head piece 2 when closing state, and it is passed to reinforced concrete foundation, the following end pivot 4 of then having installed of extension is used for the weight of grantee's word strobe.Below gate flap 1 framework, be provided with one adjustable hinge 5, its center line can be adjusted to consistent with end pivot 4 center lines, in order to the rotation gate flap.In each beam top of the centre of gate flap framework, bolster seat 3 has been installed equally, be used to bear the horizontal supporting counter-force of crossbeam when closing state, and it is passed to reinforced concrete foundation.Correct position at head piece 2 also is installed with crossette 6, is used for linking to each other with hydraulic hoist.
The utility model is the improvement to existing miter gate structure.At the lock top of miter gate two sides correct position, hydraulic hoist is installed, the piston rod hanger in its oil cylinder links to each other with crossette 6.When hydraulic hoist piston rod moving linearly, miter gate is just swung along the rotation centerline of end pivot 4 and adjustable hinge 5, reaches the purpose that Qi Menhe closes door.
