Abstract

The prefabricated lock bypass closure consists of a barrier structure and a movement mechanism, together placed in a supporting frame, with which it forms an integral assembly unit. The supporting frame also contains the bearings and seals of the barrier structure. The barrier structure can be made of plastic instead of steel, preferably polypropylene. The prefabricated lock bypass closure can be used for new construction and reconstruction of lock structures, preferably as a backup closure for quick repairs in case of malfunctions.

Description

The present invention relates to a prefabricated lock of by-pass locks embedded in a transport frame.

All types of lock lock bypasses are relatively complicated devices with complex construction and technological parts. All parts of the technology, the barrier structure, bearings, gaskets, moving mechanism and its mounts are gradually attached to the anchoring points of the building part, which is therefore highly articulated. Demanding and precise assembly work is carried out directly on the construction site, in often unfavorable conditions and in dependence on individual phases of construction, while the reconstruction or replacement of the closure is a demanding and unpleasant operation.

These drawbacks are overcome by the prefabricated lock of the locks of the locks according to the invention, which consists in that the individual parts of the prefabricated lock of the locks bypass are supported in a supporting frame of rolled steel profiles to which the bearings of the barrier structure and at least preferably, for example, linear hydraulic motors, wherein the barrier structure is provided with at least one eye for receiving the movement mechanism. If the barrier structure is a tumbler, the bearings are in the form of guide grooves which are part of the support frame and can preferably be lined with a sliding material. The barrier structure can be made of plastic, preferably polypropylene.

The main advantage of the prefabricated lock by-pass closures according to the invention is the consistent separation of assembly and construction works and their transfer to workshop conditions with higher quality, productivity and work hygiene. By arranging all the functional parts of the bypass closure into a single assembly, the construction part is also considerably simplified and the number of anchoring points is reduced. Forces are not transferred to the building part from the moving mechanism, but only from the water pressure. The installation time is kept to a minimum, including the time of replacement of the cap in case of a possible failure.

The accompanying drawings show exemplary embodiments of a prefabricated bypass lock according to the invention. FIG. 1 shows a prefabricated lock bypass lock with a multi-flap barrier structure. Giant. 2 also shows an axonometrically prefabricated lock bypass lock with a tumbler gate structure.

Example 1

The prefabricated lock bypass lock (Fig. 1) with a damper structure 2 ^with four multi-flap shutter flaps connected to each other by a drawbar 2 The bearings 2 of the individual flaps with horizontal pivot axes are rigidly connected to the supporting frame 3 ^. The flaps are actuated by a moving mechanism 5, which is a rectilinear hydraulic motor attached to the uppermost of them by the eye. To the support frame 1, the movement mechanism 5 is mounted in a grip 4 fixedly connected to the support frame.

The hinges J3, which are used for transport and storage during assembly, are also fixed to it.

Example 2

The prefabricated cap bypass locks (Fig. 2), the weirs 2 ^e s tumbler. The bearings 2 are in the form of grooves 7 which are part of the support frame 1.

Fixed to the support frame 1 is also a fixture 4 of the moving mechanism 5 formed by a linear hydraulic motor. The weirs 2 ^te said movement mechanism 5 mounted ý eye. Hinges 8 fixedly attached to the support frame 3 serve for the trans port and the mounting during assembly.

The prefabricated lock of the locks bypasses can be used for new constructions and reconstructions of locks, where they are stored in pre-built grooves in the masonry. It is advantageously used for repeated assemblies and replacements instead of damaged bypass caps. The barrier structure may consist of a tumbler, segment, flap or multi-flap closure. The control can be hydraulic or mechanical. In addition to steel, the material of the barrier structure may also be plastics, preferably polypropylene.
