Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, outriggers for lifting machines. Outrigger contains a jack. on the rod of which there is a base plate and hingedly mounted hinged shoes, on the shaft of which the pliers are installed levers, the rotation of which is limited by projections, the supporting elements on the levers, stops, springs. When the jack rod moves, the supporting elements, rolling along the grooves of the copiers, release the shoes, which under the action of their own weight unfold about the axis and occupy a horizontal position. 6 Il.

FIELD OF THE INVENTION The invention relates to lifting and transport machinery, in particular, to outrigger lifting machines.

The purpose of the invention is the convenience of operating a lifting machine. Figure 1 shows the outrigger in the transport position; figure 2 is the same in the working position; on fig.Zuzed. 1 in FIG. figure 4 - node C in figure 2; figure 5 is a section aa in figure 3; figure 6 - section bb in figure 2.

An outrigger is mounted on the frame of the lifting machine 1, containing a jack 2, on the rod 3 of which a support is installed with limited swing, consisting of a base plate 4 and pivotally fastened to it by means of an axis 5 of the folding shoes 6. Levers 8 are mounted on the shaft 7 whose turn is limited by the protrusions 9 and 10, made in the shoes. On the levers there are supporting elements 11, which in the transport position cooperate with copiers 12 mounted on the housing of the jack 2. On the supporting plate 4 there are stops 13, the working surfaces of which are perpendicular to the longitudinal axis of the levers in the working position. A lever 14 is attached to the shaft 7 and cooperates with a latch 15, which, under the influence of the spring 16, tends to turn the shaft 7 with the levers 8 into the operating position.

The outriger works as follows.

In the transport position of the anvils, the supporting elements 11, interacting with the profile grooves 17 of the copiers 12, through the screws 8, abutting against the lower protrusions 9, hold the shoes 6 in the raised position, which is necessary to ensure the minimum dimensions of the transport machine 1.

When the ram 3 of the jack is driven, the elements 11, rolling around along the grooves 17 of the copiers 12, release the shoes 6, which, under the action of their own weight, unfold relative to the axis 5 and occupy a horizontal position. In case if the effort from the own weight of the shoes 6 is not enough to turn them, the supporting elements 11 turn the levers 8 to their interaction

With the upper protrusions 10 and due to the influence of the copier 12 forcibly deploy the shoes 6 in a horizontal position. The angle of rotation of the shoes from the transport to the horizontal position is limited constructively by the hinge connection with the axis 5.

After turning the pads 6 into the working position of the spring 16, acting on the clamps 15 and levers 14, the shaft 7 is turned by levers 8 against the stop into the upper projections of the shoes 6. The end surfaces of the levers 8 are located opposite the stops 13 of the base plate 4 and when mounting the ground, resting against the working surfaces of the stops 13, prevent the folding of the folding shoes 6

The implementation of the end of the rod 3 in the form of a ball bearing provides self-support on an uneven surface. The total supporting area of the plate 4 and the shoes 6 ensures the stability of the transport vehicle 1 when hung on loose soil.

When translating the support into the transport position, the rod 3 of the jack 2, retracted, lifts the support, while the supporting elements 11, run over the copiers 12, turn the levers 8, which come out of contact with the stops 13 and, affecting the protrusion 9, unfold the shoes in transport position.

Claims (1)

Invention Formula An outriger of a lifting machine that contains a jack with a support plate fixed on its rod with folding shoes, each of which has a lever fixed to a horizontal shaft, and an installation mechanism for the shoes in a working position, characterized in that it is equipped with a copier with a symmetrical made by relative grooves relative to the longitudinal axis of the jack, fixed on the jack body, supporting elements mounted on the free ends of the levers with the ability to interact with the profile channels the aforementioned copier, and stops mounted on a base plate for interactions with the end surface of the levers, spring-loaded with respect to the shoes made with protrusions to limit the rotation of the levers in the vertical plane. //////////// / RL1 n f / rtl / / / / ///, s n f A .3 f3 § 14 Figm
