Description

A kind of arc Service gate

Technical field

The utility model relates to a kind of arc Service gate, belongs to water conservancy and hydropower equipment manufacturing technology field.

Background technology

Design specifications according to present water conservancy and hydropower industry; As the arc Service gate that is arranged in scouring sluice on the river course, sluice position when selecting port size; General all be provided with the width in aperture big than highly, be provided with more approachingly to I haven't seen you for ages, the purpose of work is the setting for the ease of arc Service gate log type gate leaf and its like this; The door body structure that is general arc Service gate all adopts two main beam structures, and respective support arms all adopts two support arm structures.The benefit that adopts described pair of main beam, two support arm structures is the material that arc Service gate gate flap and support arm are made in a large amount of saving of ability, reduces production costs.But when the ambient conditions that is limited to the scene makes that the aperture height size is big; When particularly the height dimension in aperture is more much bigger than width dimensions; If still adopt the arc Service gate of two main beams, two support arm structures; Will make special big of the length of cantilever segment of the above gate flap of arc Service gate upper branch arm, and then upper cantilever section amount of deflection is rolled up, thereby make its rigidity be difficult to satisfy code requirement.

The utility model content

The utility model technical problem to be solved is: provide a kind of under the height dimension in the aperture condition more much bigger than width dimensions, still can guarantee the arc Service gate of rigidity of the cantilever segment of the above gate flap of upper branch arm.

The technical scheme that adopts for solving the problems of the technologies described above is: a kind of arc Service gate; Comprise arc Service gate gate flap that contains main beam and support arm with the said arc Service gate of support gate flap of an openend; The openend of support arm is supported on respectively on the different main beam of the same end of arc Service gate gate flap; The main beam of arc Service gate gate flap is three; The two hatch frames of support arm openend for being made up of upper branch arm, middle support arm and lower branch arm, the upper branch arm of same support arm, middle support arm and lower branch arm are supported on respectively on three main beams of the same end of arc Service gate gate flap.

Further be, between the upper branch arm and middle support arm of same support arm, also be respectively arranged with many montants between middle support arm and the lower branch arm.

The optimal way of such scheme is, between the adjacent montant of upper branch arm and middle support arm, also be respectively arranged with at least one brace between the adjacent montant of middle support arm and lower branch arm.

Further be that the cross section of montant is and the I-shape construction of height such as corresponding support arm grade that the cross section of brace is the open web type structure that is made up of two channel-section steels.

Further be that the cross section of main beam is a box structure.

Further be that the cross section of upper branch arm, middle support arm and lower branch arm is a box structure.

The beneficial effect of the utility model is: through three main beams are set on arc Service gate gate flap and the distance between the adjacent main beam are widened as far as possible; Simultaneously the openend of corresponding support arm is set to two hatch frames of being made up of upper branch arm, middle support arm and lower branch arm; And make corresponding respectively being supported on three main beams of upper branch arm, middle support arm and lower branch arm; Can effectively reduce the length of the cantilever segment of the above arc Service gate of upper branch arm gate flap like this; Upper cantilever section amount of deflection is reduced; Even thereby make height dimension that described arc Service gate uses the aperture than under the much bigger condition of width dimensions, still can guarantee the rigidity of the cantilever segment of the above gate flap of upper branch arm.

Be labeled as among the figure: main beam 1, arc Service gate gate flap 2, support arm 3, upper branch arm 4, middle support arm 5, lower branch arm 6, montant 7, brace 8.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5 be the utility model provide a kind of under the height dimension in the aperture condition more much bigger than width dimensions, still can guarantee the arc Service gate of rigidity of the cantilever segment of the above gate flap of upper branch arm.Said arc Service gate comprises arc Service gate gate flap 2 that contains main beam 1 and the support arm 3 with the said arc Service gate of support gate flap 2 of an openend; The openend of support arm 3 is supported on respectively on the different main beam 1 of arc Service gate gate flap 2 same ends; The main beam 1 of arc Service gate gate flap 2 is three; The two hatch frames of support arm 3 openends for being made up of upper branch arm 4, middle support arm 5 and lower branch arm 6, the upper branch arm 4 of same support arm 3, middle support arm 5 and lower branch arm 6 are supported on respectively on three main beams 1 of arc Service gate gate flap 2 same ends.Through above-mentioned technical scheme; Three main beams 1 are being set on the arc Service gate gate flap 2 and the distance between the adjacent main beam 1 are being widened as far as possible; Simultaneously the openend of corresponding support arm 3 is set to two hatch frames of being made up of upper branch arm 4, middle support arm 5 and lower branch arm 6; And make corresponding respectively being supported on three main beams 1 of upper branch arm 4, middle support arm 5 and lower branch arm 6; Can effectively reduce the length of the cantilever segment of upper branch arm 4 above arc Service gate gate flaves 2 like this; The amount of deflection of this upper cantilever section is reduced, thereby, still can guarantee the rigidity of the cantilever segment of the above gate flap of upper branch arm even make height dimension that described arc Service gate uses the aperture than under the much bigger condition of width dimensions.

In order to make the upper branch arm 4, middle support arm 5 and the lower branch arm 6 that constitute support arm 3 can form firm a, intensity and stability can both satisfy the trussed construction of wanting, between the upper branch arm 4 and middle support arm 5 of same support arm 3, also be respectively arranged with many montants 7 between middle support arm 5 and the lower branch arm 6; Between the adjacent montant 7 of upper branch arm 4 and middle support arm 5, also be respectively arranged with at least one brace 8 between the adjacent montant 7 of middle support arm 5 and lower branch arm 6.

The ability that further takes the weight and carry for upper branch arm 4, middle support arm 5 and the lower branch arm 6 that improves main beam 1, formation support arm 3; Steel that again can use are minimum, and the cross section of the cross section of main beam 1 and upper branch arm 4, middle support arm 5 and lower branch arm 6 all is arranged to box structure.Same in that to bear same loading condition little; Improve the stock utilization of montant 7, brace 8 to greatest extent; Convenient simultaneously tight bar 1 is connected with lower branch arm 6 with corresponding upper branch arm 4, middle support arm 5; The cross section of montant 7 is changed to the I-shape construction with height such as corresponding support arm grade, and the cross section of brace 8 is changed to the open web type structure that is made up of two channel-section steels.
