Description
Technical field
This utility model relates to water conservancy projects, is specifically related to a kind of folding type hydraulic dam support bar.
Background technology
Hydraulic pressure dam is important water conservancy projects, and it is easy to use, is widely used.In long term production, existing liquid
Setting-out dam drawback progressively manifests, and is mainly manifested in: 1, dam body back support bar whole installation, when dam body is opened, support bar need to be along base
Seat sliding backward, stops when support bar bottom runs into river course sandstone, easily causes dam body folding fault；2, existing hydraulic pressure dam need
Join large hydraulic top, directly contribute dam holistic cost and promote；3, the hydraulic stem arm of force of existing hydraulic pressure dam is long, has caused closing effect
Rate is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in construction, and operation is efficient, stable, and can be notable
Reduce the folding type hydraulic dam support bar of manufacturing cost.
For solving above-mentioned technical problem, this utility model one folding type hydraulic dam support bar, including upper support arm and
Lower support arm；The top of described upper support arm is provided with pin-and-hole；Described lower support arm upper end is provided with square slotted eye A, described
Lower support arm lower end is provided with down square slotted eye B；Described square slotted eye A is from top to bottom sequentially provided with the second alignment pin, turns
Axle, the first alignment pin, be provided with auxiliary hydraulic top, described auxiliary hydraulic top and the second alignment pin and connect outside described lower support arm, institute
Stating the second alignment pin can be flexible in shape slotted eye A up；Upper square slotted eye A is inserted and respectively with the below described upper support arm
Two alignment pins and rotating shaft are flexibly connected；Tilting below described lower support arm have main hydraulic top, and described main hydraulic top top is provided with
Axle sleeve, described axle sleeve and the first alignment pin are flexibly connected；Under described, square slotted eye B is provided with the 3rd alignment pin.This utility model
Pin-and-hole hinged with dam body, the 3rd alignment pin is hinged with pedestal；Second alignment pin be connected with auxiliary hydraulic top and can stretch flexibly with
Realizing spacing to upper support arm, rotating shaft is spacing to upper support arm and upper support arm can be along axis of rotation.When the second alignment pin, turn
Axle is the most spacing to upper support arm and can realize the support of dam body under main hydraulic top lifting after support arm；During dam body Guan Bi, main
Hydraulic top and auxiliary hydraulic top simultaneously close off, and auxiliary hydraulic top drives the second alignment pin retraction, and the second alignment pin releases upper support arm limit
Position, upper support arm with rotating shaft for fulcrum turn clockwise downward support arm side overlapping, synchronization main hydraulic top retraction, lower support
Arm puts down；Treating that main hydraulic top completely closes, dam body opens flood discharge.Upper support arm of the present utility model and lower support arm are collapsible,
Both joint portions are unsettled, it is to avoid river course sandstone accident jam and cause dam body can not act the accident closed, be suitable to complex environment
Operation.
Preferably, described first alignment pin is arranged on the position of 1/3 above lower support arm.It meets the base that the short arm of force is arranged
Reach on plinth to close efficiency optimization state.
Preferably, described pin-and-hole, the second alignment pin, rotating shaft, the 3rd alignment pin are separately positioned on support arm and lower support
On the cross central line that arm is total.This technical scheme is used to can ensure that the steadiness that dam body supports.
To sum up, this utility model simple in construction, operation is efficient, is remarkably improved rising of hydraulic pressure dam and closes efficiency, reduces liquid
Setting-out dam manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of utility model works state.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As in figure 2 it is shown, this utility model one folding type hydraulic dam support bar, including upper support arm 3 and lower support arm
4；The top of described upper support arm 3 is provided with pin-and-hole 3a；Described lower support arm 4 upper end is provided with square slotted eye A, described lower
Brace 4 lower end is provided with down square slotted eye B；Described square slotted eye A is from top to bottom sequentially provided with the second alignment pin 4a, rotating shaft
4b, the first alignment pin 4c, be provided with auxiliary hydraulic top 8, described auxiliary hydraulic top 8 and the second alignment pin 4a outside described lower support arm 4
Connecting, described second alignment pin 4a can be flexible in shape slotted eye A up；Upper square slotted eye A is inserted below described upper support arm 3
And be flexibly connected with the second alignment pin 4a and rotating shaft 4b respectively；Tilting below described lower support arm 4 have main hydraulic top 5, described master
Hydraulic top 5 top is provided with axle sleeve 5a, described axle sleeve 5a and the first alignment pin 4c and is flexibly connected；Under described, square slotted eye B is arranged
There is the 3rd alignment pin 4d.
Described first alignment pin 4c is arranged on the position of 1/3 above lower support arm 4.
Described pin-and-hole, the second alignment pin 4a, rotating shaft 4b, the 3rd alignment pin 4d are separately positioned on support arm 3 and lower support
