Description

one

The invention relates to shipbuilding, in particular, to lifts for the delivery of welders and welding equipment to hard-to-reach spaces of ship hull sections during a set welding operation to a web in a high-performance boat method.

The proposed construction hoist can also be used in other areas of the industry when performing welding and assembly work under conditions similar to those given.

A construction elevator is known, which contains a portal mounted on rails with a vertical platform that mixes along the vertical direction and carries work sites. The purpose of the invention is to deliver workers to hard-to-reach places and narrow spaces formed vertically on the section brackets.

This is achieved by the fact that the platforms are mounted on rail conductors with the possibility of movement along the platform and are made retractable in the direction of movement of the portal.

FIG. 1 shows the proposed construction elevator in the working position; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one.

The lift consists of a movable portal 1 with vertical guides 2, a lifting platform 3, a lifting drive 4 with counterweights 5. On the portal are mounted staircases 6 with transition platforms. The platform has rail tracks

7, which can move telescopic retractable fixed platforms

8. On the platform, power supply sources 9 for welding semiautomatic devices are also installed.

In the area of staircases with transitional platforms, at the adjacent end of the platform, automatic doors 10 are installed, opening only with a fixed platform for communication with the open side of the staircases. for entry and decoder welders.

The lift works as follows.

Claims (1)

The platform 3 rises along the vertical guides of the portal 1 to a predetermined height level and stops. Portal 1 moves along the rail tracks to the section, on the stand with the required angle MfM, approaches the ends of the brackets (stiffeners) section of the portal and automatically stops. Platforms 8 of the mouth are pushed along the horizon onto rail tracks x 7 along the platform so that the extension to the part of the platform is opposite the free space between two adjacent section brackets. Thereafter, the platform 8 is fixed from moving along the rails of the platform. The telescopic part of the platform is manually extended into the space between the compartment brackets and fixed with a locking device. After adjustment, installation and fixation of all the sites, welding works are carried out on the section, while the welders are located on the sliding platforms 8 in the spaces between the brackets of the section. Upon completion of the welding work at this level of the section, the sliding parts of the platforms are removed from the space between brackets, the welding cables and equipment are removed, the platform with the welders moves to the next level, and the cycle of work is repeated. Ladder marches 6 are attached to the portal metal constructions, through which welders are provided with entry and exit from any level of platform 3 in height due to the constant alignment of the level of automatic doors on the platform with the open side of the flight of stairs. Claims of the invention A construction hoist containing a portal mounted on rails with a vertical platform that is mixed along a vertical guideway, carrying working platforms, characterized in that, for the purpose of delivering a group of welders to hard-to-reach braces formed vertically on the section, the squares are mounted on rail conductors movable along the platform and retractable in the direction of movement of the portal. 1
