Abstract
The invention discloses a steel dam gate convenient to install, and belongs to the technical field of gates. The steel dam gate convenient to install comprises a bottom shaft. The bottom shaft is supported on a plurality of hinged bases which are fixedly arranged at the bottom of a watercourse. The two ends of the bottom shaft penetrate through walls to be inserted into hoist rooms. A hoist is arranged inside each hoist room. The end portions of the bottom shaft are connected with the hoists through connecting levers. Gate leaves for stopping water are connected to the bottom shaft. The bottom shaft is connected with the walls through sealing supporting pieces. Each hinged base comprises an arc section. The bottom shaft is supported on the arc sections in a rotatable mode. The central angle of each arc section is 90 degrees to 180 degrees. A water stop piece is arranged on one side of the upper stream of the watercourse and abuts against the outer side of the bottom shaft. According to the steel dam gate convenient to install, unit-separating manufacturing according to the number of the hinged bases is not required, the number of the hinged bases can not be limited, a steel dam is wholly placed in the hinged bases after assembly is finished, taking-in-position after the assembly can be achieved, therefore, the assembly construction site and the assembly working space position are free, site installation workloads are greatly reduced, and the steel dam gate convenient to install can easily achieve sealing.
Description
Technical field
The present invention relates to a kind of water conservancy projects, particularly a kind of steel dam anchor gate.
Background technology
In the prior art, a kind of steel dam anchor gate is arranged, its structure mainly includes lower shaft, lower shaft is installed on a plurality of free bearings that river course bottom is fixedly installed, the lower shaft two ends are passed body of wall and are extend in the hoist chamber, are provided with headstock gear in the hoist chamber, and the end of lower shaft links to each other with connecting lever one end, the connecting lever other end links to each other with the cylinder piston rod external part of headstock gear, is welded on lower shaft for the gate flap that blocks water.When headstock gear is worked, can drive lower shaft by connecting lever and rotate, gate flap is erected block water or fell after discharge water.At present, reach tens meters for width, even up to a hundred meters river course, gate must the split manufacturing, the on-the-spot installation, that is to say that gate flap and lower shaft are divided into some elementary sections makes, then the elementary section gate flap is welded to connect into the elementary section member with the elementary section lower shaft in factory, during on-the-spot the installation, the elementary section lower shaft need to be passed corresponding free bearing, lower shaft and free bearing are the larger member of volume, operation easier is large during connection, and accurately the location is very difficult; For can field-strip, the elementary section member can be adopted dismountable connected mode connect, for example will be connected with bolt between the adjacent gate flap, use flange between the adjacent lower shaft, bolt is connected, because lower shaft passes free bearing and installs, rotationally support and connection between the two, the work plane of free bearing is complete circle, and the good flange of in advance welding can not pass free bearing, therefore, need in the elementary section lower shaft of that section that passes free bearing, inner flange be set, after it passes free bearing, again the outward flange of external diameter greater than the lower shaft external diameter is connected with the inner flange installation, then adjacent elementary section lower shaft could be connected.The problem that this structure is brought is: adopt flange to connect, although be easy to dismounting, lower shaft is arranged on the bottom, river course, must consider how to seal between flange and the gate flap, and the external diameter of flange forms step greater than the external diameter of lower shaft at flange connections, and sealing is also relatively difficult.
Summary of the invention
The purpose of this invention is to provide a kind of convenient steel dam anchor gate of installing, can install more easily.
The object of the present invention is achieved like this: a kind of convenient steel dam anchor gate of installing, comprise lower shaft, lower shaft is supported on a plurality of free bearings that river course bottom is fixedly installed, the lower shaft two ends are passed body of wall and are extend in the hoist chamber, be provided with headstock gear in the hoist chamber, the end of lower shaft links to each other with headstock gear through connecting lever, is connected to lower shaft for the gate flap that blocks water; Link to each other through seal support part between lower shaft and the body of wall; Described free bearing comprises arc section, and lower shaft is rotatably supported on the arc section, and the central angle of described arc section is 90 °-180 °, and upstream, river course one side is provided with sealing part and abuts in the lower shaft outside.
When the present invention works, can drive lower shaft by headstock gear rotates, gate flap is erected or fell, realization is blocked water and is discharged water, and water mainly passes to body of wall by support member to the thrust of gate flap, and free bearing bears the part weight of lower shaft and gate flap, when gate flap rotates, curved working face and wearing piece play local supporting role, guarantee that lower shaft and gate flap are indeformable, use reliable.When the lower shaft site operation was installed, lower shaft can be welded and fused, and also can directly be connected through outward flange, during installation, as long as be shelved on free bearing from the free bearing top, and need not to pass free bearing with axial manner, therefore can not produce interference between flange and the free bearing, be very easy to installation.Compared with prior art, not inventing does not need to adopt the mode of wearing axle to install, steel dam does not need the quantity subdivision manufacturing according to free bearing, free bearing quantity can be unrestricted, integral body was put into free bearing and is got final product after the steel dam assembly unit was finished, can first assembly unit in place again, so the locus of the place of assembling construction and consolidation service is all very free, greatly reduce the on-site installation work amount.Because free bearing is not that integral body is wrapped in the lower shaft periphery, as long as being set outside lower shaft and between the upstream, river course, sealing part can realize sealing, nothing is interfered between free bearing and the sealing part, so that this device also is easy to realize sealing.
For further guaranteeing that this device uses reliably, cooperate between described arc section and the lower shaft to be provided with wearing piece, described free bearing both sides are respectively equipped be used to the block that stops wearing piece.Certainly, wearing piece also can be fixed on the curved working face in other way, for example adopts groove to fix or adopts screw to fix.Wearing piece plays a part to support and is wear-resisting, and it can be bearing shell.
As a further improvement on the present invention, the arc section two ends of described free bearing are positioned on the same level height.Also can be following structure: in the height at the arc section two ends of free bearing, the height that is positioned at downstream, river course one side be higher than the height of upstream, river course one side.As long as guarantee that free bearing can support lower shaft on the whole.
As a further improvement on the present invention, the arc section end that is positioned at the downstream, river course on the described free bearing is provided with an extension.This extension can be the part of circular arc, also can be straightway, and it can guarantee that lower shaft is difficult for deviating from outside the arc section, uses more safe and reliable.
Among the present invention, can be line seal between sealing part and the lower shaft.Its sealing is simple and convenient, uses reliable, with low cost.
