Description
Technical field
The present invention relates to a kind of steel dam anchor gate, particularly the lower shaft bindiny mechanism 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 the lock wall and are extend in the lock chamber, are provided with headstock gear in the lock 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, the necessary split manufacturing of gate, 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, a kind of way is that the gate flap of adjacent cells section member and lower shaft correspondence are welded to connect, this problem of bringing is: when being welded to connect, the axiality of lower shaft is difficult to assurance, and the accurate location in the welding process is very difficult; After being welded to connect, it dismantles inconvenience, and free bearing can not be changed.Another kind of way is to adopt dismountable connected mode to connect the elementary section member, 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, 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 difficulty relatively.
In addition, in the prior art, because lower shaft passes the free bearing setting, so inevitable external diameter greater than lower shaft of the external diameter of free bearing, three sealings must be considered in this position, be respectively the sealing of the both ends of the surface of the outer circumference surface of free bearing and free bearing, need to adopt a plurality of notch cuttype seals to seal, its sealing also is difficulty comparatively.
Summary of the invention
The purpose of this invention is to provide a kind of steel dam anchor gate lower shaft bindiny mechanism, make it can not only carry out easily dismounting, can realize very easily sealing simultaneously.
The object of the present invention is achieved like this: a kind of steel dam anchor gate lower shaft bindiny mechanism, comprise the lower shaft that is formed by connecting by some elementary section lower shafts, elementary section gate flap correspondence is welded on the elementary section lower shaft, described lower shaft two ends are passed the lock wall and are extend in the lock chamber, the bottom in river course is fixed with some free bearings, cooperate the splined shaft that is equipped with external splines through bearing in the described free bearing, corresponding elementary section lower shaft end is welded to connect the spline housing with internal spline, splined shaft cooperates in the insertion spline housing, described free bearing external diameter, the external diameter of spline housing external diameter and corresponding units section lower shaft is equal, and the lower shaft two ends are provided with stopping means.
When the present invention installs, first free bearing is fixedly mounted on the concrete foundation of bottom, river course, then with splined shaft and one by one corresponding installation of free bearing, elementary section lower shaft and the splined shaft plug-in mounting that will be welded with spline housing are fixed again, and then adjacent gate flap are connected.This fixed form has guaranteed that whole device can disassemble into some unit member one by one, and free bearing also can be changed.Simultaneously, because the external diameter of free bearing external diameter, spline housing external diameter and corresponding units section lower shaft equates, so that the position that need to seal only is the periphery of spline housing periphery and free bearing, as long as employing line seal part abuts in the spline housing external surface and the free bearing external surface can be realized positiver sealing, do not need to adopt the sealing device of multiple tracks notch cuttype to seal on the whole.In addition, the bearing two ends need not to arrange separately bearing gland, simplify the structure.The lower shaft two ends are provided with stopping means, have guaranteed the location of lower shaft, and the splined shaft of plug-in mounting and spline housing can not break away from.Compared with prior art, beneficial effect of the present invention is: this technical scheme has guaranteed that lower shaft can not only carry out dismounting easily, can realize very easily simultaneously sealing, being connected the technical scheme that only is used for transmission with other field internal spline in the prior art compares, technical scheme of the present invention can also successfully solve the problem of lower shaft sealing, has obtained beyond thought effect.This device is exclusively used on the end transverse axis steel dam anchor gate.
As a further improvement on the present invention, be provided with sealing ring between described spline housing end face and the bearing face, be provided with the anti-attrition liner between spline housing end face and the free bearing end face.Sealing ring is sealed bearing better, and the anti-attrition liner can reduce the wearing and tearing between spline housing end face and the free bearing end face, has simultaneously sealing function concurrently.Install for convenient, described anti-attrition liner is fixed on the free bearing end face.
Cause corrosion in the elementary section lower shaft for avoiding water to enter, leak, be provided with waterproof bulkhead in the described elementary section lower shaft inner chamber.
As a further improvement on the present invention, be tightly connected through waterproof jacket between described lower shaft and the lock wall, cooperate the elementary section lower shaft installed one side is welded to connect spline head with external splines towards the river course with waterproof jacket, the spline housing with internal spline of corresponding units section lower shaft end welding cooperates installation with described spline head with external splines, spline head external diameter equates with elementary section lower shaft external diameter, also is provided with the anti-attrition liner on the step surface between spline head and the spline housing.This technical scheme has solved the problem of the easy accessibility of the elementary section lower shaft that passes lock wall part, so that installing with the scene in later stage, the Embedment Construction of concrete foundation do not conflict, guaranteed to seal easily between gate flap and the lock wall between lower shaft and the lock wall.
