Description

. The invention relates to hydraulic engineering and can be used to install and remove closures of hydraulic structures.

A device for maneuvering hydraulic gates is known, comprising a drive, a beam, guide wheels, a gripper assembly tl.

It is also known a device for maneuvering the gates of a hydraulic structure, comprising a frame connected to a lifting mechanism, a clutch mechanism mounted on the frame with a gate mounted in the grooves of the structures f2j.

A disadvantage of the known devices is that, in the case of using wheel locks, this leads to their complication due to the presence of complex wheel bearing and running gears, and in the case of using sliding locks, reliability is reduced, operation due to the possibility of jamming of the shutter and difficult operation , due to the need for a mechanism of significant carrying capacity;

The purpose of the invention is to increase the reliability of operation and simplify operation. The goal is to achieve a tendency that the device is equipped with hydraulic cylinders and wheels with 1: 1 carriages mounted on the frame with the ability to move the cylinders perpendicular to the frame plane, and the slots for the ramlide are made at the bottoms of the lower edge of the gate.

FIG. 1 schematically depicted

10 is a device coupled with a bolt in the groove during the maneuvering process; 2 — view A in FIG. If on fig.Z section bb in fig. 2

The device consists of a frame 1, with a mobile lifting mechanism connected to the suspension (suspension and mechanism are not shown in the drawing), serving a series of flat closures 2. To the frame 1 from the pressureless side

20 attached balancing wheeled undercarriage 3, which are located in the slots 4.

The wheeled trolleys 3 are mounted in the bushings 5, which can be moved by the hydraulic cylinder b 25 in the axle box 7 relative to PAMJ 1.

The frame 1 is equipped with a control link 8 which can be connected to a 30 gate 9 on the flat gate 2. The clutch 8 is driven by a hydraulic cylinder 10. The hydraulic system of the device operates from an oil pressure unit .11, which is powered and controlled by a mobile lifting mechanism. The groove 4 has paths 12 for moving the wheeled undercarriage bodies 3 along it and an additional recess with the supporting shelf 13 for resting the gate 2 on them when it receives a hydrostatic load. The device works as follows. To install the bolt into the hole attached to the suspension in front of the movable lifting mechanism, the device is brought to the stand in the gate (special storage area) gate 2 and the coupling 8, moved by the hydraulic cylinder 10, is connected to the attachment unit. Then the hydraulic cylinders 6 of the wheeled undercarriage 3 are shifted in the box boxes 7, due to which the frame 1, in the white. the pressure face of the bolt 2 moves it to a position in which it does not touch the support flange 13 of the groove 4. In this position, the device is installed in the grooves 4 of that hydraulic hole in which the bolt 2 is to be installed and lowers along them to the threshold. At the same time, the movement of the shutter, perception; the thrusting head and supported on the frame 1 occurs on the wheeled undercarriage 3, which rolls along the path of 12 slots 4. After lowering the device with the shutter. The 2 wheeled undercarriage 3 is driven by hydraulic cylinders 6 to frame 1, the bolt 2 is displaced in the direction of the bottom runner under the action of pressure, and rests on the support shelf 13 of the groove a. 4. The wheeled carts 3 are unloaded. A gap is formed between the free-flow side of the shutter 2 and 1. By the hydraulic cylinder 10, the coupling 8 detaches the shutter 2 from the frame 1, after which the device is removed by a mechanism from the groove 4, in which the shutter 2 resting on the flanges 13 of the groove 4 remains, blocking the hydraulic hole. Removing shutter 2 is performed in the reverse order. Such an implementation of the proposed device will improve the reliability of its work and simplify operation. Apparatus for maneuvering gates of a hydraulic structure, comprising a frame connected to a lifting mechanism, a clutch mechanism mounted on the frame with a slide installed in the structure construction abutments, characterized in that, in order to increase reliability and simplify operation, it is equipped with hydraulic cylinders and wheel carriages mounted on the frame with the ability to move the cylinders perpendicular to the plane of the frame, and at the heights from the bottom edge of the gate us grooves for accommodating the frame.
