Abstract
The utility model discloses a steel dam bed shaft in the technical field of steel dam gates. The steel dam bed shaft comprises a hollow tubular shaft body, wherein an inner flange is arranged at one end of the shaft body, an outer flange is arranged at the other end of the shaft body, shaft sleeves are sleeved on the shaft body at intervals, the shaft sleeves and the shaft body are welded and connected into a whole, and the shaft sleeves are made of stainless steel materials. When the steel dam bed shaft is installed, the shaft sleeves are passed through a hinged seat from one end of the inner flange, the shaft body can be arranged in the hinged seat, the shaft sleeves and the shaft body are sealed and fixed, the shaft sleeves are smooth in surfaces, and the steel dam bed shaft is easy to machine and convenient to install. Compared with the prior art, the steel dam bed shaft has the advantages that the hinged seat and the bed shaft can be ensured to be conveniently connected, and the steel dam bed shaft is reliable in use and long in service life, and is easy to prevent corrosion and rusting.
Description
Technical field
The utility model relates to a kind of gate, particularly a kind of lower shaft of steel dam anchor gate.
Background technology
In China's urban water conservancy engineering, in the fields such as water conservancy projects construction and environmental renovation, irrigation, flood control, steel dam is just by utilization widely.
Steel dam anchor gate of the prior art, its structure comprise gate flap, are fixed on the lower shaft and the drive unit of gate flap bottom, and it is overhanging that the lock wall is passed at the two ends of lower shaft; Its overhanging end is connected with drive unit; Have some free bearings that distribute vertically on the lower shaft, and on gate flap and lower shaft, have one group of water seal arrangement, this device contains the water seal arrangement between lower shaft and the lock wall; The bottom seal device of lower shaft, the side seal device between gate flap and the lock wall.
For making things convenient for the dismounting of lower shaft, the steel dam lower shaft can be divided into multistage, is connected by flange each other; Promptly inner flange is set at hollow axis body one end; The other end is provided with outward flange, connects an outward flange at inner flange one end, is connected with the outward flange of adjacent axis body through the outward flange that inner flange one side connects in addition again; Because the external diameter of inner flange is less than the external diameter of axis body, so it can insert smoothly in the axis hole on the free bearing and installs.Because lower shaft and free bearing need mate installation, the finish of lower shaft is had relatively high expectations, and lower shaft contacts with water for a long time, its requirement for anticorrosion is higher, and lower shaft of the prior art still can not reach above-mentioned requirements.
The utility model content
The purpose of the utility model provides a kind of steel dam lower shaft, and the work plane that itself and free bearing are assembled is corrosion-resistant and highly polished.
The purpose of the utility model is achieved in that a kind of steel dam lower shaft, comprises the tubulose axis body of hollow, and axis body one end is provided with inner flange, and the axis body other end is provided with outward flange, and spacer sleeve is equipped with axle sleeve on the said axis body, and said axle sleeve and axis body are welded to connect and are one.
Above-mentioned axle sleeve can be processed by stainless steel material.When it is installed, axle sleeve is passed free bearing, can axis body be installed in the free bearing from inner flange one end, sealing and fixing between axle sleeve and the axis body, the axle sleeve any surface finish is easy to processing, easy for installation.Compared with prior art, the beneficial effect of the utility model is: this device can guarantee that free bearing and lower shaft are easy to connect, uses reliably, is easy to realize anticorrosion, anti-corrosion, the long service life of lower shaft.
Cause corrosion and sedimentation for reducing in the water entering axis body, two ends are respectively equipped with shrouding in the said axis body.Through shrouding sealing lower shaft inner space, avoid water and silt to get into.
For ease of welding, be welded to connect between said inner flange, outward flange and the axis body, the welding position in the axis body is provided with gasket ring.Gasket ring can stop that welding slag and motlten metal get in the axis body, make welding more convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 inner flange, 2 axis bodies, 3,6 shroudings, 4 axle sleeves, 5,8 gasket rings, 7 outward flanges.
The specific embodiment
Shown in Fig. 1-4, be a kind of steel dam lower shaft, comprise the tubulose axis body 2 of hollow, axis body 2 one ends are provided with inner flange 1, and axis body 2 other ends are provided with outward flange 7, and spacer sleeve is equipped with axle sleeve 4 on the said axis body 2, and said axle sleeve 4 is welded to connect with axis body 2 and is one; Above-mentioned axle sleeve 4 is processed by stainless steel material; Two ends are respectively equipped with shrouding 3,6 in the axis body 2; Be welded to connect between inner flange 1, outward flange 7 and the axis body 2, the welding position in the axis body 2 is provided with gasket ring 5,8.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
