SU69530A1 - Device for stepped lifting loads with a jack - Google Patents

Description

The invention relates to well-known devices for lifting loads by means of a jack mounted on a jack-beam and supporting a supporting nadjack beam between two columns supported by shoes and employees for successive attachment of a support and jack jack at different levels. In such devices, the lifting is carried out in a series of successive operations with the corresponding alternate fastening of the supporting beams.

To communicate a certain horizontal movement to the load, the connection of each column with a base box and a support beam with a jack is made hinged.

FIG. 1 and 2 the general view of the proposed device is shown in two projections, and FIG. 3-8 are axonometric projections of the individual components of the device, namely: in FIG. 3 and 4 - columns, in FIG. 5 - bashmak with a hinge, in FIG. b - sub-double beam, in (Fig. 7 - jack,. in Fig. -8 - support on the beam with hinged support for cargo.

The operation of the proposed sleep device of FIG. 1 and 2, in which the starting and ending positions of the load and parts of the device during lifting are shown in dotted lines. As it rises, the gap between the columns from the shoe to the subcomplete beam is filled with a cage made of scraps of I-beams and channel beams, fastened together by short electric welding seams.

Subject invention

A device for stepped lifting of loads using a jack, comprising two columns supported on shoes, which are used to successively mount the supporting and jack-type beams at different levels, characterized in that, in order to communicate to the lifted load of some horizontal movement, the connection of each column with the shoe and the support beam with the jack is articulated.
