Abstract
The utility model discloses a wall-through sealing device for a steel dam bottom shaft in the field of gates, which comprises a waterproof sleeve embedded into a wall. The bottom shaft penetrates through a central hole of the waterproof sleeve, an inner step is arranged on one inner side of the central hole close to water, a shaft sleeve is disposed in the waterproof sleeve in a matched manner, a wear-resistant lining is arranged on the inner side of the shaft sleeve, the wear-resistant lining is sleeved outside the bottom shaft, one side of the shaft sleeve axially is attached to the inner step, filler is arranged on the other side of the shaft sleeve and positioned in an annular gap between the bottom shaft and the waterproof sleeve, a pressure cap is arranged on one side of the central hole far away from the water, the pressure cap axially compresses the filler, and the pressure cap and the waterproof sleeve are connected via compression screws. Since the shaft sleeve and the wear-resistant lining are disposed in a hinge seat, the filler in the annular gap can be guaranteed to be constantly, peripherally and uniformly compressed between the waterproof sleeve and the bottom shaft to function in fine sealing, the problem that an existing water sealing device between a bottom shaft and a gate wall is difficult to realize reliable water sealing, and thereby the wall-through sealing device is fine in sealing and reliable in use.
Description
Technical field
The utility model relates to a kind of gate, is used for the water seal arrangement between lower shaft and the lock wall on particularly a kind of steel dam.
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 used widely.
In the prior art, a kind of gate is arranged, its publication number is: CN2581498Y, and its structure comprises gate flap, is fixed on the lower shaft and the drive unit of gate flap bottom, and it is protruding that the lock wall is passed at the two ends of lower shaft, its two axial ends is connected with drive unit, have some free bearings that are provided with vertically on the lower shaft, and have one group of water seal arrangement on gate flap and lower shaft, 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.Its weak point is: in the prior art, the water seal arrangement between lower shaft and the lock wall is difficult to realize reliable water seal, and its reason is, as simple employing packing seal, because the easy compressibilty of filler, after a period of time running, filler loses sealing function because of distortion easily.
The utility model content
The utility model is in the prior art, is difficult between lower shaft and the lock wall to realize the problem that seals propose a kind of steel dam lower shaft sealing device through walls, makes good seal between lower shaft and the lock wall, uses reliable.
For solving the problems of the technologies described above, technical solutions of the utility model are as follows: a kind of steel dam lower shaft sealing device through walls, comprise the waterproof jacket that is embedded in advance in the body of wall, lower shaft passes the centre bore of waterproof jacket, side near water in the described centre bore is provided with step in, be equipped with axle sleeve in the waterproof jacket, described axle sleeve inboard is provided with anti-wearing liner, anti-wearing liner is sleeved on outside the lower shaft, axle sleeve one side shaft is provided with filler to abutting in interior step in axle sleeve opposite side and the annular gap between lower shaft and waterproof jacket, and centre bore is provided with gland away from a side of water, described gland compresses filler vertically, is connected through housing screw between gland and the waterproof jacket.
In the utility model, axle sleeve and anti-wearing liner are arranged in the free bearing, can play good positioning action to lower shaft, avoid occurring axle and beat, can guarantee that like this filler in the annular gap can circumferentially be pressed between waterproof jacket and the lower shaft all the time equably, play good sealing function.Compared with prior art, the beneficial effects of the utility model are: it can guarantee the sealing through walls of lower shaft for a long time, avoids leaking, and makes its good seal, uses reliable.
For reducing wear, reduce friction factor, energy efficient, the dependability of raising device is provided with oil sealing between described axle sleeve and interior step, and the movable sealing face of described oil sealing is sleeved on the lower shaft outer round surface.Lubricating grease can be sealed in the oil sealing inboard, and lubricate between anti-wearing liner and lower shaft can reduce wearing and tearing between the two.Simultaneously, lubricating grease and oil sealing also have the effect of water seal concurrently.
For further improving sealing reliability, be provided with the O RunddichtringO between the internal circular surfaces of described interior step and the lower shaft.
Be easy disassembly, described gland comprises two half blocks, is connected with connecting bolt through engaging lug between two half blocks.Unclamp connecting bolt, two half blocks can be separated from each other from the lower shaft both sides and take out, and have made things convenient for dismounting.
For further facilitating installation, described gland edge circumferentially is evenly equipped with some radial openings, and described housing screw snaps in the radial opening and also with between the waterproof jacket is threaded.Housing screw can and be packed into from the side direction taking-up, can reduce the space that the gland end is reserved, and makes device compact more.
