SU43611A1 - The device separating the shaft with hydraulic lifts from the lowering chamber of the gate of hydraulic structures - Google Patents

Description

It is known in hydraulic structures to use hydraulic lifts, so-called dives for maneuvering the gates of these structures. These hydraulic lifts are different with respect to the closures and to the body of the structure, and may, for example, be located in a special shaft.

The proposed invention is a device that separates the shaft from the lowering chamber of the gate and aims to obtain sufficient water resistance while ensuring the necessary movements of the connecting rod.

Lifting mechanisms for the gates of the dam shown in FIG. 1-4, consist of hydraulic oscillating cylinders 19 with pistons and connecting rods connected to the body of the bolt 27, and are placed under the lowering chamber 20 of the sector bolt in vertical waterproof shafts 22 arranged in the body of the dam and provided with maintenance and repair accessory 23 In dams that do not have bychosis, inspection passages run along the entire dam and end with vertical exits at its ends. In rafts with intermediate bulls, observation tunnels connect the vertical shafts with a number of these bulls. FIG. Figures 1 and 2 show bridges 24 of the Poaret dam type for repairing the dam.

Under each gate, depending on its length and weight, two or more shafts are arranged, with one or several hydraulic cylinders placed in each shaft (r 5-7). Each span of the dam, i.e. the distances to the mecchu of adjacent dam bulls, may consist of one or more sector gates with two or more shafts for hydraulic lifts. If, due to local conditions, the presence of bulls in the river is unacceptable, then the entire length of the dam from coast to coast is divided into the required number of sectoral gates in contact with each other.

FIG. 8-16 depict another embodiment of a dam using Example 5 of the invented device. Internal circular valves pass the flow of the river through the dam body, for which holes 2 / rectangular section are arranged in the dam, separated from each other by transverse walls 25, 25. Within the limits of movement of the gates, the ceiling of each hole has a notch of 24 segmented shape (in section across the dam) with the center coinciding with the center of rotation of the gates. Each shutter serves several openings and for its passage through the transverse walls, through holes 26 are made in them in Gzid half of the circle, and the diameters of these semi-circles are located at an angle of 45 °

to horizontal. Adjacent closures are separated from each other by deaf transverse walls 25 with niches 27 of the same semicircular cross section in order to accommodate the supporting structures of the closures. The carrier structure of the closures consists of transverse trusses of a sector-shaped grid with lattice filling (Fig. 12). The sectoral outline of the transverse truss is formed by two radial rods converging at right angles and a third rod running along an arc of a circle. The load-bearing structure of the skin along an arc of a circle consists of longitudinal beams connected to the arc rods of transverse trusses. The internal grid system is selected depending on the height of the closures. In gates of small heights, transverse trusses may consist of three external rods without an internal lattice or have a solid wall (Fig. 13). The transverse trusses are located at the ends of the closures along the middle longitudinal walls of the blind walls and along the remaining length of the closures along the middle longitudinal axes of the transverse walls, section ush, and through holes for the water. The bearings for the axes of the valves rest on the diametrical surfaces of the semicircular niches and cuts in the transverse walls inclined at an angle of 45. To repair the valves, the holes in the body of the dam are closed on the side of the upper and lower tails of the shield. The shields are put in place with the help of locomotive cranes moving along a crane track laid on the crest of the dam.

FIG. 14-16 show a cross section of a dam with external pie and internal segment gates. External sectoral gates in dams of this type have a minimum height sufficient to allow ice flow (1-2 m) without raising the level of the upstream. When the seals along the front wall along the axis of rotation and at the ends of the gate, such dimensions of the valves ensure that the lowering chamber is always dry and that stationary hydraulic cylinders are placed to raise the shutter not in the shafts, but in the lowering chamber itself (Fig. 14-15). shutters, despite their small

height, spans of arbitrary length. The repair barrier of external gates is designed as separate shields with rods attached to a two-light service and road bridge. The flaps are lowered by rotating the rods with a crane moving along the upper shaft of the bridge.

The proposed device separating the shaft of the hydraulic lift from the chamber is as follows (Figs. 17-30). The metal cover / is attracted by bolts to the flange of the pipe 2, embedded in the masonry of the dam. A longitudinal slot 3 is arranged in order to pass the swinging rod-rod of the hydraulic lift in the lid, the length of which corresponds to the swing amplitude of this rod. A hollow cylinder 4 is bolted to the cover, so that its longitudinal axis coincides:; with the axis of the slot. For the passage of the rod 7 / connecting rod through the cylinder in its wall, at the top and at the bottom, two longitudinal slits 5-6 are made, with the upper slit 5 coinciding with the slit in the cover. Inside the cylinder, the piston 7 moves, hollow on the sides and solid in the middle part. In the middle of the solid part of the piston, a hole 78 is drilled (fig. 21) and a continuous insert 8 is inserted into it (fig. 22-22). This liner is placed so that its longitudinal axis lies in the same plane: With the longitudinal axis of the piston and intersects with it at a right angle. The hole in the piston drilled for a solid liner is closed on both sides by plugs 9 (Fig. 23,23) with cylindrical outer surfaces that coincide with the cylindrical surfaces of Piston 7 and countersunk screws W attached to it (Fig. 21). For a cylindrical rod 7 / connecting rod, a hole 77 is drilled in a solid liner 8 corresponding to the diameter of the rod. In addition, in order to allow the connecting rod to swing, cuts 72 are made in the solid part of the piston. Such a structure, separating the shaft from the chamber, gives free translational and swinging movement of the connecting rod.

The moving parts of the piston and the solid cylinder visible from above are protected from water leaching of grease and rust by a rubber tire 75 having an appearance of an overturned funnel. The narrow part of the tire is fastened by means of a clamping ring J4 (Fig. 24) with an oil seal 75 (Fig. 25, 25), which is put on the rod of the connecting rod, and a wide part of the tire is pressed against the cover by a ring J6, bolted on.
