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 prior art, there is a kind of steel dam anchor gate, its structure mainly includes lower shaft, lower shaft is arranged on multiple free bearings that bottom of river channel is fixedly installed, lower shaft two ends extend in lock chamber through lock wall, and be provided with headstock gear in lock chamber, 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, is welded on lower shaft for the gate flap blocking water.When headstock gear works, drive lower shaft to rotate by connecting lever, gate flap is erected and blocks water or discharged water after falling.At present, tens meters are reached for width, the even river course of up to a hundred meters, the necessary split manufacture of gate, in-site installation, that is gate flap and lower shaft to be divided into some elementary sections to manufacture, then elementary section gate flap is welded to connect into elementary section component with elementary section lower shaft in factory, during in-site installation, a kind of way is welded to connect the gate flap of adjacent cells section component and lower shaft correspondence, this problem brought is: when being welded to connect, the axiality of lower shaft is difficult to ensure, 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 adopts dismountable connected mode to connect elementary section component, such as be connected between adjacent gate flap with bolt, with flange between adjacent lower shaft, bolt is connected, because lower shaft is through free bearing installation, support and connection rotationally between the two, and the flange welded in advance can not pass free bearing, therefore, need to arrange inner flange in the elementary section lower shaft of that section through free bearing, pass after free bearing until it, the outward flange again external diameter being greater than lower shaft external diameter is installed with inner flange and is connected, then adjacent elementary section lower shaft could be connected.The problem that this structure is brought is: adopt Flange joint, although be easy to dismounting, lower shaft is arranged on bottom of river channel, 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, form step at flange connections, sealing relative difficulty.
In addition, in prior art, because lower shaft is arranged through free bearing, 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 multiple notch cuttype seal to seal, its sealing is also comparatively difficult.
Summary of the invention
The object of this invention is to provide a kind of steel dam gate bottom shaft bindiny mechanism, make it can not only carry out dismounting easily, sealing can be realized very easily simultaneously.
The object of the present invention is achieved like this: a kind of steel dam gate bottom shaft bindiny mechanism, comprise the lower shaft be 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, through bearing fit, the splined shaft with external splines is installed in described free bearing, corresponding elementary section lower shaft welding edges is connected with 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 is equal, lower shaft two ends are provided with stopping means.
When the present invention installs, first free bearing is fixedly mounted in the concrete foundation of bottom of river channel, then splined shaft and free bearing one_to_one corresponding is installed, then the elementary section lower shaft and splined shaft plug-in mounting that are welded with spline housing are fixed, then adjacent gate flap is connected.This fixed form ensure that whole device can become some unit member by broken, 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, make to need the position carrying out sealing to be only the periphery of spline housing periphery and free bearing, as long as adopt line seal part to abut in spline housing external surface on the whole and free bearing external surface can realize positiver sealing, do not need to adopt the sealing device of multiple tracks notch cuttype to seal.In addition, bearing two ends, without the need to arranging bearing gland separately, simplify the structure.Lower shaft two ends are provided with stopping means, ensure that the location of lower shaft, and the splined shaft of plug-in mounting and spline housing can not depart from.Compared with prior art, beneficial effect of the present invention is: this technical scheme ensure that lower shaft can not only carry out dismounting easily, sealing can be realized very easily simultaneously, with other field internal spline in prior art connect only for transmission technical scheme compared with, technical scheme of the present invention successfully can also solve the problem of lower shaft sealing, achieves beyond thought effect.This device is exclusively used on 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 bearing face, between spline housing end face and free bearing end face, be provided with anti-attrition liner.Sealing ring can 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.
Enter in elementary section lower shaft for avoiding water and cause corrosion, leak, in described elementary section lower shaft inner chamber, be provided with waterproof bulkhead.
As a further improvement on the present invention, be tightly connected through waterproof jacket between described lower shaft and lock wall, coordinate the elementary section lower shaft installed to be welded to connect spline head with external splines towards side, river course with waterproof jacket, the spline housing with internal spline of corresponding units section lower shaft welding edges coordinates with the described spline head with external splines to be installed, spline head external diameter is equal with elementary section lower shaft external diameter, and the step surface between spline head and spline housing is also provided with anti-attrition liner.This technical scheme solves the problem of the easy accessibility of the elementary section lower shaft through lock wall part, the Embedment Construction of concrete foundation is not conflicted with the in-site installation in later stage, ensure that between lower shaft and lock wall, can seal easily between gate flap and lock wall.
