Dam, jacking system is generally two hydraulic jacks.Support system is generally linkage, and with locked cylinder (on hydraulic pressure dam
It is raised to locked during final position), to ensure when hydraulic cylinder is not having pressure oil, what hydraulic pressure dam can be stablized is in terminal position
Put.These conventional hydraulics folding dam structure is relatively complicated, and support bar is not two power bars, easily by bending stress.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hydraulic foldable dam of the forked type bar with mechanical self-latching,
The device efficiently solves conventional hydraulic and folds dam complex structure, can only rely on other locked hydraulic cylinder to fix lacking for door leaf
Fall into.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of hydraulic foldable dam of forked type bar with mechanical self-latching, including the dam foundation, and the door leaf being flexibly connected with the dam foundation, institute
State and support meanss are provided between the dam foundation and door leaf, the support meanss there are two groups, every group of lower link for including being connected with the dam foundation, with
And the upper connecting rod being connected with door leaf, the upper connecting rod and lower link are flexibly connected.
Further improvement is that, provided with the hydraulic cylinder being fixedly connected with the dam foundation, the hydraulic cylinder below the support meanss
Provided with piston rod, a rotating shaft has been crossed on the top of the piston rod, and the upper connecting rod lower end and lower link upper end all
Concatenation forms forked type bar structure in this rotating shaft.
Further improvement is that, the dam foundation and door leaf are respectively equipped with attachment means, the attachment means by connecting plate and
The interval insertion support meanss in the middle of the projection composition on connecting plate, the projection are disposed on, and use rotating shaft string respectively
Connect.
Further improvement is that, when the angle α of the upper connecting rod and lower link formation increases in the range of 0 ° to 180 °,
Hydraulic cylinder is all to produce motive force, promotes door leaf to rise；When angle α is 180 °, hydraulic cylinder is not rotated pair by connecting rod pair and made
With；When angle α is more than 180 °, hydraulic cylinder 5 is by the secondary pulling force effect of connecting rod.
Further improvement is that, during the pulling force effect of the hydraulic cylinder under tension connecting rod pair, hydraulic cylinder is in maximum row
Journey position, just forms self-locking.
Further improvement is that, described upper connecting rod and lower link is the double link structure be arrangeding in parallel.
Further improvement is that, the two ends of the rotating shaft are provided with the clamp nut for being used for preventing that upper and lower connecting rod from coming off.
The beneficial effects of the utility model are：
1) structure is compacter, directly supports door leaf relative to supporting cylinder, the stroke of hydraulic cylinder can be very long；
2) due to mechanical self-latching structure, therefore two locked hydraulic cylinders are reduced；
3) all connecting rods are all two power bars, and structure is relatively reliable, and connecting rod is only stressed or pulling force, relative to hydraulic pressure in upper figure
Dam, lower link is by very big bending stress；
4) support meanss are double link structure, more firmly, and will not be produced in motion process with hydraulic cylinder support bar
Interference.
5) hydraulic cylinder greatly reduces support force, reduces the chi of hydraulic cylinder directly in the support of upper and lower strut motion vice division chief
It is very little, improve reliability.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, a kind of hydraulic foldable dam of forked type bar with mechanical self-latching, including the dam foundation 1, and it is movable with the dam foundation 1
The door leaf 2 of connection, provided with two groups of support meanss between the dam foundation 1 and door leaf 2, every group of lower link 3 including being connected with the dam foundation 1, with
And the upper connecting rod 4 being connected with door leaf 2, upper connecting rod 4 and lower link 3 are flexibly connected.It is provided with to fix with the dam foundation 1 below support meanss and connects
A rotating shaft 7, and lower end and the lower link of upper connecting rod 4 are crossed in the hydraulic cylinder 5 connect, the top of the piston rod 6 of the hydraulic cylinder 5
3 upper end is all concatenated in this rotating shaft 7, forms forked type bar structure.
The dam foundation 1 and door leaf 2 are respectively equipped with attachment means, and attachment means are by connecting plate 8 and are disposed on connecting plate 8
Projection 9 is constituted, the interval insertion support meanss in the middle of projection 9, and is concatenated respectively with rotating shaft 7.The two ends of rotating shaft 7, which are provided with, to be used for
Prevent the clamp nut 10 that upper and lower connecting rod comes off.
Particularly, upper connecting rod 4 and lower link 3 are the double link structure be arrangeding in parallel.
When hydraulic pressure dam door leaf 2 fell, the angle α of upper and lower connecting rod formation is the acute angle of very little, with the liter of hydraulic cylinder 5
Rise, angle α slowly increases, until 180 °, during this, hydraulic cylinder 5 is all to produce power, promotes door leaf 2 to rise, hydraulic cylinder
5 in itself by the secondary pressure of connecting rod.When angle α is 180 °, hydraulic cylinder 5 is not rotated pair by connecting rod pair and acted on.When angle α is big
When 180 °, hydraulic cylinder 5 is by the secondary pulling force effect of connecting rod.
This hydraulic cylinder 5 is exactly that hydraulic cylinder 5 is changed into pulling force from being stressed, now hydraulic cylinder when being more than 180 ° using angle α
5 are in maximum travel position, just form self-locking.Now hydraulic cylinder 5 becomes a connecting rod by pulling force, with the lower company being stressed
The formation wishbone of bar 3, supports whole door leaf 2 to be in the position jointly, and can not move, and now hydraulic pressure dam is in mechanical self-latching shape
State.
