Description
Technical field
The utility model relates to a kind of steel dam anchor gate, particularly the lower shaft bindiny mechanism of steel dam anchor gate.
Background technology
In prior art, there is a kind of steel dam anchor gate, its structure mainly includes lower shaft, lower shaft is arranged on a plurality of free bearings that river course bottom is fixedly installed, lower shaft two ends extend in lock chamber through lock wall, are provided with headstock gear in lock chamber, and the end of lower shaft is connected with connecting lever one end, the connecting lever other end is connected with the cylinder piston rod external part of headstock gear, for blocking the gate flap of water, is welded on lower shaft.When headstock gear is worked, can drive lower shaft to rotate by connecting lever, gate flap is erected block water or fell after discharge water.At present, for width, reach tens meters, the river course of up to a hundred meters even, the necessary split manufacture of gate, on-the-spot installation, that is to say that gate flap and lower shaft are divided into some elementary sections manufactures, then elementary section gate flap is welded to connect into elementary section member with elementary section lower shaft in factory, during on-the-spot 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: while being welded to connect, the axiality of lower shaft is difficult to assurance, and the accurate location in 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 elementary section member, for example will between adjacent gate flap, with bolt, be connected, between adjacent lower shaft, use flange, bolt is connected, because lower shaft is installed through free bearing, support and connection rotationally between the two, and the flange having welded in advance can not pass free bearing, therefore, need in the elementary section lower shaft of that section through free bearing, inner flange be set, after it passes free bearing, the outward flange that again external diameter is greater than to lower shaft external diameter is installed and is connected with inner flange, 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 bottom, river course, must consider how to seal between flange and gate flap, and the external diameter of flange is greater than the external diameter of lower shaft, at flange connections, form step, sealing is difficulty relatively.
In addition, in prior art, because lower shaft is through free bearing setting, so the external diameter of free bearing must be greater than the external diameter of lower shaft, three sealings must be considered in this position, be respectively the sealing of the outer circumference surface of free bearing and the both ends of the surface of free bearing, need to adopt a plurality of notch cuttype seals to seal, its sealing is also comparatively difficult.
Utility model content
The purpose of this utility model is to provide a kind of steel dam anchor gate lower shaft bindiny mechanism, makes it can not only carry out easily dismounting, can realize very easily sealing simultaneously.
The purpose of this utility model is achieved in that a kind of steel dam anchor gate lower shaft bindiny mechanism, comprise the lower shaft being formed by connecting by some elementary section lower shafts, elementary section gate flap correspondence is welded on elementary section lower shaft, described lower shaft two ends extend in lock chamber through lock wall, the bottom in river course is fixed with some free bearings, in described free bearing, through bearing fit, the splined shaft with external splines is installed, corresponding elementary section lower shaft end is welded to connect the spline housing with internal spline, splined shaft coordinates in insertion spline housing, described free bearing external diameter, the external diameter of spline housing external diameter and corresponding units section lower shaft equates, lower shaft two ends are provided with stopping means.
When the utility model is installed, first free bearing is fixedly mounted in the concrete foundation of bottom, river course, then by splined shaft and free bearing corresponding installation one by one, then the elementary section lower shaft and the splined shaft plug-in mounting that are welded with spline housing is fixed, then adjacent gate flap is 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 is equal, making the position that need to seal is only the periphery of spline housing periphery and free bearing, as long as employing line seal part abuts in spline housing external surface and 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, bearing two ends, without bearing gland is set separately, simplify the structure.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 depart from.Compared with prior art, the beneficial effects of the utility model are: this technical scheme has guaranteed that lower shaft can not only carry out dismounting easily, can realize very easily sealing simultaneously, only be connected and compare for the technical scheme of transmission with other field internal spline in prior art, the technical solution of the utility model can also successfully solve the problem of lower shaft sealing, has obtained beyond thought effect.This device is exclusively used on end transverse axis steel dam anchor gate.
As further improvement of the utility model, between described spline housing end face and bearing face, be provided with sealing ring, between spline housing end face and free bearing end face, be provided with anti-attrition liner.Sealing ring is sealed bearing better, and anti-attrition liner can reduce the wearing and tearing between spline housing end face and free bearing end face, has sealing function concurrently simultaneously.For convenience of installing, described anti-attrition liner is fixed on free bearing end face.
For avoiding water to enter, in elementary section lower shaft, cause corrosion, leak, in described elementary section lower shaft inner chamber, be provided with waterproof bulkhead.
As further improvement of the utility model, between described lower shaft and lock wall, through waterproof jacket, be tightly connected, coordinate the elementary section lower shaft of installing one side is welded to connect the spline head with external splines towards river course with waterproof jacket, the spline housing with internal spline of corresponding units section lower shaft end welding coordinates installation with the described spline head with external splines, spline head external diameter equates with elementary section lower shaft external diameter, is also provided with anti-attrition liner on the step surface between spline head and spline housing.This technical scheme has solved the problem through the easy accessibility of the elementary section lower shaft of lock wall part, the Embedment Construction of concrete foundation and the scene in later stage are installed does not conflict, guaranteed, between lower shaft and lock wall, between gate flap and lock wall, can seal easily.
