FIELD OF THE INVENTION The invention relates to hydraulic structures, in particular, safety devices for the airlock of the gateway.

The purpose of the invention is simplification. s device instructions.

FIG. shows the gateway with the safety device of the gates of the lower head at the time of the ship's pile, plan view; in fig. 2 - section A-A on 10 ug. one; on fig.Z - section bb in fig.G; 4 shows a safety device at the moment of its beginning, a plan view; 5 - the same, with the rod extended and the fixed body of the hydraulic shock absorber fixed; Fig. 6 - the same, when sliding the housing of the hydraulic auger onto the rod {the moment of its termination); rfa of FIG. 7 is a section bb of FIG. A; on Fig - section 20 GGD on fig.Z; figure 9 is a cross-section dD in figure 6; in fig. 10 - safety device in dimetry; Fig. II is a diagram of the operation of the hydraulic shock absorber at the time of the start of the stem drawing; 35 in FIG. 12 - the same, at the moment of sliding the body of the hydraulic shock absorber onto the rod.

The safety device gate 1 of gateway 2 contains hydraulic shock absorbers 3, installed against each other's JQ in the niches of the walls of gateway 2. Each hydraulic shock absorber 3 consists of a housing 4 in which a piston 5 with a stem 6, a system of oil lines 7 and throttles 8 are placed (FIG. and 12). The safety device is equipped with a guide frame 9, in which the housing 4 of the hydraulic shock absorber 3 is installed. It can be moved on the supporting and running elements 10. The end stops AND are connected to the housing A of the hydraulic shock absorber 3, which cooperate with sliding clamps 12 placed in the guide frame 9. Rod 6 the hydraulic shock absorber is equipped with a chassis frame 13 with additional stops 14, made in the form of two elements mounted at the ends of the chassis frame 13 adjacent to the guide frame 9. Limiters 15 are placed on the running frame Paivbi 9 guiding surfaces in its middle part. The flexible tool body 16 (rope), the end of which is thrown over the guide block 17, is attached to the U-shaped auxiliary frame 18, the ends 19 of which are placed in the limit guides 20 on the body 4 of the hydraulic shock absorber 3, made 35

with end stops 21, the second ones are equipped with buffers 22 and retractable latches 23. The chassis frame 13 is equipped with end stops 24, which interact with retractable latches 23 of the L-shaped frame 18. The latter is made with an emphasis 25, for example, a spring buffer that interacts with the stop 26 fixed on the guide frame 9 in its final position, and to return it and the body 4 of the hydraulic shock absorber 3 to its original position and to tension the working body 6 after the vessel has been piled up, a return counterweight 27 connected by a cable block bond in 28 with n -shaped frame 18 (Figure 10). The guide frame 9 is installed in the guide rails 29.

The safety device operates as follows.

The safety device of gate 1, before introducing the vessel into gateway 2, is prepared for the perception of the ship’s pile energy, i.e. The rod 6 of the hydraulic shock absorber 3 is pushed into the housing 4. The latter is fixed to the end stops 11 by the sliding clamps 1 in the extreme position (FIGS. 4, 10 and P). The chassis frame .13 with the rod is fixed in an L-shaped frame 18 by sliding clamps 23 for the end stops 24 (FIG. 7). The flexible member is pulled over a U-shaped frame 18 and a cable block system 28 using a return counterweight 27 (FIG. 10). .

Naval the vessel on the flexible working body 16 when approaching the gate at the entrance to the gateway 2 causes its tension. The guide block 17 is bent, the rope of the flexible working body 16 transmits the force to the U-shaped frame 8j, which in turn, with the help of the clamp 23 and the stops 24, carries the chassis 13 with the rod

6 and a piston 5. The latter squeezes the oil from the rod part through the choke 8 through the system of oil lines

7c in the piston part, as a result of which a braking force occurs (FIG. P). After the movement of the rod 6 with the running frame 13 before the contact of the stops 14 with the limiters 15

and the L-shaped frame 18 along the guides 20 until the buffers 22 come into contact with the stops 21, the limit switches are triggered (not shown in FIGS. 5 and 8), and the sliding locks

12 and 23 release the end stops 1 on the housing A of the hydraulic shock absorber 3 and, accordingly, the stops 24 of the chassis frame 13.

The housing 4 of the hydraulic shock absorber 3 is fascinated by the U-shaped frame 18 while further stretching the flexible member 16, the end of which is embedded in the U-shaped frame 18, and slides over the rod 6, moving in the guide frame 9, resting on the supporting and running elements 10 (Fig.6, 9 and 12). At the same time, the oil already from the piston part (Fig. 12) is throttled into the stem part, creating a braking force. In this case, the rod 6 remains stationary.

For a ship pass (Figures 2 and 3) after Emptying the gateway 2 in case of insufficient surface clearance under the safety device, 5 the latter can be raised to the required height beyond the niche limits using lifting mechanisms. Before the next vessel enters the gateway 2, the hydraulic shock absorber 3 is returned by the counterweight 27 to the initial position, the hull 4 being fixed to the extendable stops. 11 with locking pins 12 in the guiding frame 9, and running frame 13 with stops 24 in a U-shaped frame 18 with locking pins 23.
